[0002] Sliding door safety device
[0004] Technical field
[0006] [0001] The present invention relates to security devices for sliding doors, and specifically, to a security device for a sliding door that opens and closes to the left and to the right, said device being designed to prevent fingers from or other parts of the body are damaged by being caught between a frame on the opening side and a frame on the side of the sliding door when the sliding door is opened and closed.
[0008] Previous technique
[0010] [0002] In general, sliding doors that open and close to the left and right, double-leaf sliding doors and simple sliding doors, and so on, are known. These sliding doors have a problem that fingers or other body parts can be inadvertently damaged when caught between the opening side frame and the sliding door frame, when the sliding door is opened and closed.
[0011] [0003] Thus, various safety devices have been suggested to prevent a finger or other part of the body from being damaged by being trapped between the frame on the opening side and the frame located on the side of the sliding door when it is opened. and the sliding door is closed, as can be seen, for example, through PTL 1 and PTL 2.
[0012] [0004] In the safety device described in PTL 1, a stop, whose tip protrudes when falling on one of the rails of the sliding door, is mounted on a frame located on the side of the base, so that can go up and down. The stop is forced to go down as necessary to limit the sliding door's movement, preventing the fingertips from being trapped between the sliding door and the frame.
[0013] [0005] The security device described in PTL 2 includes a main body constructed so that it can be attached to a portion located near a rear end of the upper part of a sliding door, said body being equipped with a coil spring to accumulate a repulsive force contrary to the closing direction upon movement of the sliding door in the opening direction, a rotating main gear connected consecutively to said coil spring, an oil damper located adjacent to the coil spring, to control the repulsive forces of the coil spring by rotating a sub gear coupled to the main gear, a frame coupled to the main gear and having a rear end or both front and rear ends coupled to a device on a B-frame body of an aperture A for deployment in a sliding door operating direction. Movement in the closing direction is controlled by the oil damper so that the sliding door does not close abruptly, thus preventing finger tips from being trapped.

[0019] [0006] PTL 1: Unexamined Japanese Patent Application, Publication No. 2006-2346 PTL 2: Unexamined Japanese Patent Application, Publication No. 11-152955
[0021] Summary of the invention
[0023] Technical problem
[0025] [0007] As described above, in the invention described in PTL 1, the stop must be kept raised or lowered manually. In this way, the problem can arise that the task is cumbersome and is carried out, forgetting the change of position, which can be dangerous, since the safety device does not work.
[0026] [0008] On the other hand, in the invention that is described in PTL 2, taking into account that an oil damper is used, when the sliding door is closed the problem occurs that the resistance presented by the oil damper is left feel and requires exerting great force to close.
[0027] [0009] Thus, a technical problem arises that must be solved in order to provide a safety device for a sliding door, so that the device automatically prevents fingers or other parts of the body from being trapped, even when it has not been operated. the stopper manually, and allows the sliding door to close smoothly without resisting when the sliding door is closed. The resolution of said problem constitutes one of the objects of the present invention.
[0029] Solution to the problem
[0031] [0010] The present invention is suggested to achieve the object described above, and the invention described in claim 1 provides a security device for a sliding door, capable of moving from one side to the other to cover and uncover an opening, including said device a guide frame and an approach plate that is fixed independently to the side of the opening and to the side of the sliding door, so that they are facing each other, where the guide frame includes a main configured guide element so as to have a C-shaped cross section with a top wall member connecting and securing the front and rear side wall plate member pair and the upper end sides of the wall plate member pair front and rear and incorporating a guide passage, so that the approach plate passes between the pair of elements of the side wall plates, providing each of the elements of the pair of front and rear wall plate elements being attached to a limiting groove and installing a slow-moving groove extending in a left-right direction along a moving direction of the door slide and a locking groove consecutively connected to the slow moving groove and having a stop element, and a disk rolling element comprising a disk element and a penetrating shaft element longitudinally through the center of the disk element, in order to integrate with the disk element, the shaft element movably engaging the inside of the limiting grooves in the left-right direction, and the disk element being positioned so that it protrudes towards the inside of the guide passage, and where the approach plate includes a contact face that, when colliding with the disk element with a predetermined force or greater than this, moves the shaft element from the inside of the slow moving groove towards the stop element of the locking groove, to block the movement of the disk rolling element in the left-right direction and prevent the approach plate from moving together with the sliding door towards the closing side.
[0032] [0011] According to this structure, when the sliding door is slowly closed normally to make the contact face of the approach plate and the outer peripheral surface of the disk element of the disk rolling element contact each other , the disc rolling element is guided in the slow moving groove so that it rolls and moves in the closing direction of the sliding door (substantially horizontal direction: direction A). This operation causes the approach plate to also move together with the disk rolling element in the closing direction of the sliding door, thus allowing the sliding door to close completely. On the contrary, when the sliding door initiates an abrupt closing, the contact face of the approach plate will abruptly come into contact with the outer peripheral surface of the disk element located on the disk rolling element with a predetermined or greater force than the itself, and the rolling disk element will move in one direction (direction C) of a vector resulting from the closing direction of the sliding door (substantially horizontal direction: direction A) and a direction orthogonal to the contact face of the sheet approach (direction B) and the shaft member moves from inside the slow moving slot into the locking slot. The disc rolling element then travels along the locking groove of the guide frame and then becomes locked between the stopper of the locking groove and the contact face of the approach plate to pass into the locked state, automatically inhibiting any further movement of the approach plate towards the closing side together with the sliding door. In this way, it is possible to prevent a finger or other part of the body from being inadvertently caught during the opening / closing operation of the sliding door and to prevent a great noise from being produced.
[0033] The invention described in claim 2 provides the security device for the sliding door, in which, in the structure described in claim 1, the contact face is realized as an inclined surface so that it rises from a front face of a direction of movement of the approach plate in a direction towards a rear side of the direction of movement.
[0034] According to this structure, when the sliding door starts to close abruptly, the contact face of the approach plate comes into abrupt contact with the outer peripheral surface of the disk element located on the disk rolling element with a predetermined force or greater than it, and the disk rolling element moves smoothly in the direction (direction C) of the vector resulting from the closing direction of the sliding door (substantially horizontal direction: direction A) and the direction orthogonal to the inclined contact face of the approach plate (direction B) and the shaft element moves smoothly from inside the slow-moving groove towards the stop element.
[0035] [0014] The invention described in claim 3 provides the security device for the sliding door in which, in the structure described in claim 1 or 2, the slow moving slot of the limiting slot is configured as a slit-shaped groove, and the locking groove of the limiting groove is inclined at a predetermined angle from the opening side to the closing side of the slow-moving groove.
[0036] According to this structure, when the locking groove is made to be inclined with respect to the slow moving groove, the contact face of the approach plate comes into abrupt contact with the outer peripheral surface of the disk element of the disk rolling element with a predetermined force or greater than it. When the disk rolling element escapes in the direction (direction C) of the vector resulting from the closing direction of the sliding door (substantially horizontal direction: direction A) and the direction orthogonal to the inclined contact face of the approach plate ( direction B), the shaft element can be guided towards the stop element by the inclined face arranged in the locking groove and reliably locked.
[0037] [0016] The invention described in claim 4 provides the security device for the sliding door in which, in the structure described in claims 1, 2, or 3, the stop element limits the movement of the element shaft of the disc rolling element towards the closing side of the sliding door.
[0038] [0017] According to this structure, the shaft element which has been moved into the locking groove can be reliably stopped by the stop element and can always be safely locked in a certain position.
[0039] [0018] The invention described in claim 5 provides the security device for the sliding door in which, in the structure described in claims 1, 2, 3, or 4, the locking groove is configured as an elongated hole connected to the stop member and as a curved surface protruding outward and away from the slow moving slot.
[0040] [0019] According to this structure, with the elongated hole of the locking slot configured as a curved surface that protrudes outward and away from the slow moving slot, as is the case with the disk rolling element, if it occurs a design error between the direction (direction C) of the vector resulting from the closing direction of the sliding door (substantially horizontal direction: direction A) and the direction orthogonal to the inclined contact face of the approach plate (direction B) and the orientation of the lock groove, the error is absorbed by said curved surface, and the disk rolling element can be smoothly moved into the lock groove to be securely locked.
[0041] [0020] The invention described in claim 6 provides the security device for the sliding door in which, in the structure described in claims 1, 2, 3, 4, or 5, the locking groove is configured as a branch of a series of branches that branch off, including the slow moving slot.
[0042] [0021] According to this structure, it is possible to make a configuration such that, when the disk rolling element moves in the closing direction and the shaft element is locked once on the stop element located inside the the lock slot, the lock is not released unless the approach plate is returned to the opening direction until the approach plate is disengaged from the lock slot together with the disk rolling element. Thus, the lock can be performed reliably.
[0043] [0022] The invention described in claim 7 provides the safety device for the sliding door in which, in the structure described in claims 1, 2, 3, 4, 5, or 6, the stop element of the locking slot is made with an inclined shape relative to the slow moving slot.
[0044] [0023] According to this structure, to release the state in which the disc rolling element moves towards the closing direction and the shaft element of the disk rolling element is locked inside the locking groove, when The force holding the contact face of the approach plate and the disk element of the disk rolling element is no longer exerted, the axle element disengages from the stop element of the locking groove to return to the interior of the groove slow moving, the lock being easily released to allow movement in the closing direction again.
[0045] [0024] The invention described in claim 8 provides the security device for the sliding door in which, in the structure described in claims 1, 2, 3, 4, 5, or 6, the limitation slot includes a closing direction end slot that allows the disc rolling element to escape away from the approach plate when the approach plate is moved to a predetermined direction relative to the guide frame to allow further displacement of the approach plate approach towards a closing direction, as well as an end slot in the opening direction that allows the disc rolling element to escape away from the approach plate when the approach plate returns to a predetermined position relative to the guide frame to allow further movement of the approach plate in the opening direction.
[0046] [0025] According to this structure, the sliding door is allowed to be moved by the approach plate from inside the guide frame to a closed position to then return to an open position with the approach plate passing through the interior of the guide frame.
[0047] [0026] The invention described in claim 9 provides the security device for the sliding door in which, in the structure described in claims 1, 2, 3, 4, 5, 6, 7, or 8, the Limiting groove includes a disc rolling element retraction groove that causes the disc rolling element to retract and be retained outside of the guide passage.
[0048] According to this structure, when the safety device is not required, the disk rolling element is allowed to escape into the retraction groove of the disk rolling element to be located outside the guide passage. This overrides the safety device, and allows the use so that the approach plate does not collide with the disk rolling element even as it passes through the interior of the guide passage. On the other hand, when the safety device is required, the disk rolling element is made to return from inside the retraction slot of the disk rolling element to the slow moving slot, thereby making the security device return to a valid state for use.
[0049] [0028] The invention described in claim 10 provides the security device for the sliding door in which, in the structure described in claims 1, 2, 3, 4, 5, 6, 7, 8, or 9 , the pair of front and rear side wall plate elements and the upper wall element of the guide main body are each formed as a separate body.
[0050] [0029] According to this structure, the pair of elements of the front and rear side wall plates and the upper wall element of the guide main body can be made individually, which facilitates their manufacture. Also, each of them is made as a separate element, which facilitates the design and assembly of the main body of the guide and the rolling disk element.
[0052] Advantageous effects of the invention
[0054] [0030] According to this structure, when the sliding door starts to close abruptly, the contact face of the approach plate abruptly collides with the outer peripheral surface of the disk element belonging to the disk rolling element with a predetermined force or higher than it, and the disc rolling element moves to a direction (Direction C) of a vector resulting from the closing direction of the sliding door (substantially horizontal direction: Direction A) and a direction orthogonal to the contact face of the approach plate (Direction B), the shaft member is moved from the inside of the slow-moving slot into the stop member of the locking slot, and the disk rolling member is very soon trapped between the stopper member of the slot lock and the contact face of the approach plate to automatically go into a locked state, preventing any further movement of the approach plate towards the closing side together with the sliding door. In this way, it is possible to prevent a finger or other part of the body from being inadvertently caught during the opening / closing operation of the sliding door and prevent a loud noise from being produced.

[0078] Description of the achievements
[0080] [0032] To achieve the objective of providing a security device for a sliding door, so that the device automatically prevents the entrapment of a finger or other part of the body, even when the stop is not operated manually, and that allows the sliding door closes smoothly without resisting when the sliding door is closed, said safety device for a sliding door capable of making movements in both directions, in order to cover and uncover an opening, is achieved by configuring the device so that said device include a guide frame and an approach plate that are separately fixed on the opening side and on the side of the sliding door so that they are facing each other, where the guide frame includes a main body of the guide configured in shape having a C-shaped cross section, with a top wall connecting and securing the pair of front wall plate elements and rear and upper ends of the pair of front and rear side wall plate elements and is provided with a guide passage where the approach plate passes between the pair of side wall plate elements and the pair of front limiting grooves and rear with which the pair of front and rear side wall plate elements are respectively provided and where each of them has a slow moving groove, arranged to extend from left to right along a direction of movement of the sliding door, a locking slot consecutively connected to the slow moving slot and having a stop element, a disk rolling element consisting of a disk element and a shaft element penetrating longitudinally through the center of the element disc to integrate with the disc element, where the shaft element is movably coupled inside the front and rear slow-moving groove pair in left-right direction and the disk element is located so that it protrudes into the guide passage, and the plate The approach includes a contact face which, upon collision with the disk element of the disk rolling element with a predetermined force or greater than it, moves the shaft element of the disk rolling element from within the slow moving groove. towards the stop element of the locking groove in order to block the movement of the disk rolling element in the left-right direction and prevent the approach plate from moving together with the sliding door towards a closing side.
[0081] [0033] Various embodiments for the implementation of the present invention will be described in detail in the following paragraphs, based on the attached figures. It should be noted that, in the following description, the same components are assigned the same reference numerals throughout the description of the embodiments. Likewise, the representations, such as front-back, upper-lower, left-right, etc., which indicate directions, are not intended to be absolute, and are suitable as an orientation about the part of the security device for the sliding door of the present An invention being reflected, but when that orientation changes, it should be interpreted as having been changed based on the change in orientation.
[0083] Realizations
[0085] [0034] Figures 1 to 4 show a first embodiment of a security device 10 for a sliding door (hereinafter simply referred to as security device 10) according to the present invention. Figure 1 is a side view of the security device 10 seen from the front, Figure 2 is a side view of the security device 10 seen from the direction of the line AA of Figure 1, Figure 3 is an external view in perspective of the security device 10, and figure 4 is an exploded perspective view of the security device 10. In the following description, the description is made by taking, in figure 3, an arrow in the direction ab as the direction front-rear of the safety device 10, a arrow in the direction cd as the right-left direction of the security device 10, and an arrow in the direction ef as the up-down direction of the security device 10. Also, the description is made by taking the direction of an arrow c as the position fully closed, an arrow in the direction d as the fully open position, and further a surface shown in Fig. 1 as the front face.
[0086] [0035] In Figures 1 to 4, the safety device 10 is configured as a guide frame 11 that is fixed in the appropriate position of an upper body of the frame that forms the opening of a door, window or the like, not shown, and an approach plate 12 that is fixed in a suitable place on a sliding door, which is also not shown, that covers and reveals the opening. Note that, depending on the mode of use, the guide frame 11 can be attached to one side of the sliding door and the approach plate 12 can be attached to one side of the body of the sliding door frame. In any case, the guide frame 11 and the approach plate 12 are fixed in the appropriate positions so that they face each other, and can also slide and engage each other.
[0087] [0036] The guide frame 11 includes a main body of the guide 13 and a rolling disk element 14 incorporated into the main body of the guide 13.
[0088] [0037] The main body of the guide 13 has a pair of front and rear side wall plate elements 13a and 13b and an upper wall element 13c connecting the upper end sides of the pair of plate elements. front and rear side wall 13a and 13b, and has a guide passage 20 where the approach plate 12 passes between the pair of elements of the front and rear side wall plates 13a and 13b to form a C-shaped cross section in a side view.
[0089] [0038] The upper wall element 13c has, as shown in figure 4 (and in figure 2, figure 3), a horizontal connecting plate element 113c and a vertical plate element 213c falling vertically from the center of the horizontal connecting plate element 113c in an integrated way, which in a side view appears configured in a T-shape.
[0090] [0039] On the left and right sides of the horizontal connecting plate element 113c of the upper wall element 13c are plate-shaped connecting base elements 313c, 313c configured to extend from the vertical plate member 213c in the left-right direction (the direction of the arrow cd in FIG. 3). In each of the connecting base members 313c, 313c a vertical penetrating connecting hole 22 is made.
[0091] [0040] Additionally, on the horizontal connection base plate 113c, three toothed elements 24 are configured which are substantially equidistant at positions on each of the front and rear sides through the vertical plate element 213c so as to separate in the left right direction. Note that the width of each toothed element 24 in the left-right direction is L1. Also, the number of teeth of the toothed element 24 from the front and rear sides is substantially equivalent to the plate thickness t of the side wall plate elements 13a and 13b (see Figure 4), and thus the toothed element 24 is configured so that the notches are in a position that is in contact with the vertical plate member 213c.
[0092] The vertical plate element 213c has substantially equidistant connection holes 26, configured so that they can be penetrated in the front-rear direction. Also, the vertical plate element 213c has a toothed element 28 configured from a lower end towards an upper end (the side of the upper wall element 13c). The position of toothed element 28 corresponds substantially to a locking position (stopper element 38b2) of a locking groove 38b located in a limiting groove 38, which is described in greater depth below. The toothed element 28 forms a space that allows the disk rolling element 14 that has moved upward (in the direction of arrow e) through the locking groove 38b to escape to the side of the upper wall element 13c without colliding. with the vertical plate member 213c.
[0093] The pair of elements of the front and rear side wall plates 13a and 13b are configured in substantially symmetrical shapes. On one side of the upper end of this pair of front and rear side wall plate elements 13a and 13b, convex elements 30 are located in correspondence with toothed elements 24 of the upper wall element 13c. Each convex element 30 is configured so that the width L1 in the left-right direction is equal to the width L1 of each toothed element 24 of the upper wall element 13c in the left-right direction, and is configured such that it protrudes towards up over a length substantially equal to the thickness of the plate t of the upper wall element 13c. This allows the convex elements 30 of the pair of side wall plate elements 13a and 13b to precisely fit the respective toothed elements 24 of the upper wall element 13c, and the inner surfaces of the pair of side wall elements 13a and 13b come into close contact with both surfaces of the vertical plate member 213c. Therefore, when the pair of front and rear side wall plate elements 13a and 13b are combined with the top wall element 13c, as shown in Figure 2 and Figure 3, the guide passage is formed. 20 with its bottom side and the two left and right sides open between the pair of front and rear side wall plate elements 13a and 13b.
[0094] Also, of the pair of front and rear side wall plate elements 13a and 13b, the front side wall plate element 13a is provided with coupling holes 32 in correspondence with the respective coupling holes 26 of the coupling element. vertical plate 213c located on the upper wall element 13c, and the rear side wall plate element 13b is provided with coupling holes 34 in correspondence with the respective coupling holes 26 of the vertical plate element 213c of the upper wall element 13c . And in a state in which the pair of front and rear side wall plate elements 13a and 13b and the top wall element 13c are combined, when the coupling screws 36 are screwed from one side wall plate element 13a sequentially through the coupling holes 32 and the coupling holes 26 into the coupling holes 34 for tightening and fixing, the pair of front and rear side wall plate elements 13a and 13b and the top wall element 13c can be fully fixed.
[0095] [0044] Furthermore, in each of the pairs of front and rear side wall plate elements 13a and 13b, a constraint groove 38 is configured substantially symmetrically shaped and arranged to be hollowed out in the anterior-posterior direction.
[0096] The limiting slot 38 is configured by: a slow moving slot 38a configured as a slot with an elongated hole designed to extend along a direction of movement of the sliding door, ie, the left-right direction (the direction of the arrow cd in figure 3); and a locking slot 38b connected consecutively to the slow moving slot 38a, designed to be one of the branches branching off the root of the slow moving slot 38a, and which is configured as an elongated hole.
[0097] The slow moving slot 38a is configured, as shown in FIG. 5, so that it is inclined with respect to a lower side 40 of the pair of front and rear side wall plate elements 13a and 13b rising from a full opening side (the side of arrow d in figure 3) towards a full closing side (the side of arrow c in figure 3) and forming an angle 01. Note that angle 01, in the present realization, it is substantially 2.19 degrees.
[0098] [0047] In the same way as described in Fig. 5, the locking groove 38b is configured as a curved surface R which arches continuously from one end of the opening direction 38a1 of the slow moving groove 38a. Note that the arcuate curved surface R is configured as the curved surface R with a curvature that is substantially equal to that of a circle drawn with a radius R1 taking as the center O1, a point away downward from a lower side 40a of the pair of Front and rear side wall plate elements 13a and 13b at a distance S1 and away from a right side 40b towards a left side 40c of the pair of front and rear side wall plate elements 13a and 13b at a distance S2. In the present embodiment, S1 equals 50 millimeters, S2 equals 35.1 millimeters, and R equals 65 millimeters.
[0099] [0048] The disk rolling element 14 has a disk element 14a configured in the form of a disk located inside the guide passage 20 of the main body of the guide 13 and a shaft element 14b penetrating through the center of the disk element 14a in the anterior-posterior direction and is integrated with disk element 14a, with both ends engaged and located within the front and rear limiting grooves 38 of the main body of the guide 13. The shaft element 14b is configured so that its diameter is substantially equivalent to a dimension that allows movement in the constraint groove 38 when engaged within the constraint grooves 38, that is, a dimension equivalent to the width of the groove of limiting slots 38. On the other hand, the disk element 14a is configured to have a diameter that does not allow contact with the lower surface of vertical plate element 213c of upper wall element 13c when shaft element 14b travels within constraint groove 38 .
[0100] [0049] An example of an assembly method of the guide frame 11 configured above will be described below. First, prior to the assembly of the main body of the guide 13, the front and rear ends of the shaft element 14b belonging to the rolling disk element 14 are coupled to the limitation grooves 38 configured in the pair of plate elements. front and rear side wall 13a and 13b. Also, the convex elements 30 of the pair of front and rear side wall plate elements 13a and 13b closely fit within the toothed elements 24 of the upper wall element 13c to pass into a state in which the pair of elements of front and rear side wall plate 13a and 13b is located on the front and rear sides of the top wall member 13c.
[0101] [0050] Then, the fixing screws 36 are screwed and fixed from one side of the side wall plate element 13a, through the fixing holes 32 and the fixing hole 26, into the fixing holes 34. From In this way, the pair of front and rear side wall plate elements 13a and 13b and the top wall element 13c are integrally fixed, and the guide passage 20 extending in the left-right direction is configured inside the guide main body 13. Simultaneously, the disk rolling element 14 is also mounted inside the guide main body 13. The disk rolling element 14 mounted inside the guide main body 13 is positioned in such a way that the disk element 14a protrudes into the guide passage 20 and the shaft element 14b is retained so that it can move within the limitation groove 38.
[0102] [0051] The approach plate 12 is configured to have a plate thickness slightly less than the width of the guide passage 20 of the main body of the guide 13 in the anterior-posterior direction, and integrally has a plate element of control 12a circulating inside the guide passage 20 in the left-right direction (the arrow in the direction cd of figure 3) and a connecting element 12b located at one end (bottom side end) of the plate element control plate 12a and located outside the guide passage 20. Also, the control plate element 12a has a contact face 12c that rests, towards the inside of the guide passage 20, on the outer peripheral surface of the control element. disk 14a on disk rolling element 14 so as to face disk plate element 14a.
[0103] [0052] The contact face 12c of the approach plate 12 is configured, as shown in Figure 6, as an inclined surface that rises from the full closing side towards the full opening side so that the angle formed with one face of the upper end 112b of the coupling element 12b being 02. Note that the angle 02, in the embodiment, is 71.5 degrees.
[0104] [0053] In the previously configured safety device 10, the guide frame 11 is attached in the appropriate place of the body of the upper frame forming the opening of a door, window or the like, and the approach plate 12 is fixed to a place of the sliding door, covering and uncovering the opening. In this case, the guide frame 11 and the approach plate 12 are located in a positional relationship such that when the guide frame 11 moves together with the sliding door to open or close it, in an open / close direction ( In the direction of the arrow cd in FIG. 3), the control plate element 12a of the approach plate 12 passes through the inside of the guide passage 20 of the guide frame 11.
[0105] [0054] Figure 7 shows some diagrams in which the operation of the security device 10 of the first embodiment above is described. Next, by means of FIG. 7, the operation of the security device 10 described in FIGS. 1 to 6 will be described. In the security device 10 of this embodiment, when the sliding door is moved towards the fully opening side, the Approach 12 also moves to the fully open side in conjunction with the sliding door. Also, the disk rolling element 14 of the guide frame 11 rolls to one side of the end of the opening direction 38a1 of the limitation slot 38 by the inclination (angle 01) of the slow-moving slot 38a rising from the side of full opening (arrow side d) to the full closing side (arrow side c), and stops at the end of the opening direction 38a1.
[0106] [0055] Next, when the sliding door is moved from the fully open side to the fully closed side, the approach plate 12 also moves to the fully closed side together with the sliding door. When the approach plate 12 is moved to a position midway to the full closing side, as shown at (a) in Figure 7, the contact face 12c of the approach plate 12 rests on the outer peripheral surface. of the disk element 14a of the disk rolling element 14.
[0107] In this contact, if the contact face 12c of the approach plate 12 rests slowly and normally on the disk element 14a of the disk rolling element 14 at low speed, the approach plate 12 slowly presses the rolling element disk 14 in the closing direction (horizontal direction). Then, the disk rolling element 14 is moved together with the approach plate 12 towards the full closing side as the axle element 14b rolls into the slow moving slot 38a. Also, as shown in (b) in Fig. 7, when the shaft member 14b of the disk rolling member 14 reaches the end of the closing direction 38a2 of the slow moving slot 38a, the sliding door reaches the state of full closure, completely covering the opening.
[0108] On the contrary, when the sliding door starts to close abruptly, the contact face 12c of the approach plate 12 collides with the outer peripheral surface of the disk element 14a of the disk rolling element.
[0109] 14 with a predetermined force or greater than it. Next, the rolling disk element 14 is moved, by means of a force exerted on the side of an approach plate 12 with a vector resulting from a closing direction of the sliding door (substantially horizontal direction: Direction A) and an orthogonal direction to the inclined contact face 12c of the approach plate 12 (Direction
[0110] B) as shown in Figure 7 (a), towards a direction of said resulting vector (Direction C) and, as shown in (c) in Figure 7, the axis element 14b is displaced from inside the slow-moving slot 38a along curved surface R into locking slot 38b. Also, the disk rolling element 14 is pushed by the approach plate 12, and moves from one end of the full opening side 38b1 to the closing element. stop 38b2 of locking groove 38b. When the shaft element 14b of the disk rolling element 14 moves towards the stopper element 38b2, contacting the stopper element 38b2 and the shaft element 14b causes the movement of the disk rolling element 14 to stop, and the plate approach 12 also stops in that position in conjunction with the sliding door. That is, the sliding door is prevented from going to the fully closed state, and this stop prevents a finger or other part of the body from being trapped between the sliding door and a pillar or bar, and also prevents the sliding door from colliding with the pillar during opening, causing a great noise.
[0111] [0058] Likewise, in order to make the sliding door leave the inactivity state in order to make the transition to the complete closed state again, the approach plate 12 returns, together with the sliding door, to the fully open side at a distance S3 shown at (c) in figure 7. Next, the disc rolling element 14 returns to the full opening side at distance S3 due to the inclined shape of the locking groove 38b, and soon falls from the inside of locking slot 38b into slow moving slot 38a to return into slow moving slot 38a. Subsequently, the sliding door moves back to the full closing side, the disk rolling element 14 is again pushed by the approach plate 12 in the closing direction (horizontal direction), and moves together with the approach plate 12 towards the full closing side as the shaft member 14b rolls into the slow moving slot 38a. Next, as shown in (b) in Figure 7, the shaft element 14b of the disk rolling element 14 very soon reaches the end of the closing direction 38a2 of the slow-moving groove 38a, and upon reaching this point, the sliding door goes to the fully closed state, completely covering the opening.
[0112] Likewise, when the sliding door is opened again, the sliding door moves towards the fully open side. Next, following the displacement of the approach plate 12 towards the full opening side, the disk rolling element 14 also rolls down the inclination of the slow moving slot 38a to return to the opening direction end 38a1 of the slot. slow moving 38a. Subsequently, the device waits until the sliding door closes again. So when it is closed, the same movement is repeated.
[0113] Therefore, according to this safety device 10 of the first embodiment, when the sliding door is slowly closed normally, it can be closed to the fully closed position. On the contrary, when the sliding door is abruptly closed, the shaft element 14b automatically moves from the interior of the slow-moving slot 38a into the locking slot 38b by the inclination of the contact face 12c of the approach plate 12, and the disk rolling element 14 is very soon caught between the stop element 38b2 of the locking groove 38b and the contact face 12c of the approach plate 12, thus initiating the locking state. Then, the approach plate 12 is prevented from moving further together with the sliding door towards the closing side, and thus it is possible to prevent a finger or other part of the body from being inadvertently caught during the opening / closing operation. of the sliding door, as well as preventing a great noise from being produced.
[0114] [0061] Likewise, after locking, said lock is automatically released when the sliding door travels the distance S3 and the operation can be carried out again until it reaches the complete closed state, thereby simplifying its operation.
[0115] Furthermore, the shape of the locking groove 38b is configured as the curved surface R with a curvature equivalent to that of a circle drawn with a radius R1. In this way, when the disc rolling element 14 moves towards the side of a locking slot 38b, the shaft element 14b moves into the locking slot 38b along said curved surface R. This allows that the movement is smooth.
[0116] Additionally, by changing the shape of the curved surface R of the locking groove 38b and the shape of the gradient of the contact face 12c of the approach plate 12, that is, the angle 02, the area Operation of the lock operation and other operations can be easily changed.
[0117] Note that the direction of each of the vectors described above can be freely changed by adjusting the angle of inclination of the guide frame 11 or the approach plate 12. And by changing the direction of each vector, it is also possible to variably adjust the operating speed of the sliding door that has started to lock.
[0118] [0065] Additionally, the angle of inclination of the guide frame 11 or of the approach plate 12 can be easily adjusted by an adjustment mechanism using a screw or the like.
[0119] Additionally, the spontaneous sound that occurs when the disk rolling element 14 and the approach plate collide sharply with each other can be absorbed by arranging a shock absorbing mechanism (such as a rubber or a shock absorber) between the frame of guide 11 or the approach plate 12 and a window or window frame. With absorption, silencing can also be achieved.
[0120] [0067] Figures 8 and 9 show a second embodiment of the security device 10 according to the present invention. Figure 8 is a side view of the security device 10 seen from the front, and Figure 9 is a side view of the security device 10 seen from the direction of a line BB of Figure 8. In the configuration of this second embodiment The structure of the limitation groove 38 of the guide frame 11 and the shape of the gradient (angle 02) of the contact face 12c in the approach plate 12 are modified, and the rest of the structures are identical to those of the figures 1 to 7, and thus identical components are assigned the same reference numerals, with any redundant description omitted.
[0121] In Fig. 8 and Fig. 9, as in the first embodiment, the limiting slots 38 provided to the pair of front and rear side wall plate elements 13a and 13b, respectively, are configured to have forms substantially symmetrical and are hollowed in the anterior-posterior direction.
[0122] [0069] Each of the limiting grooves 38 comprises: a slow moving groove 138a configured to extend along a direction of movement of the sliding door, that is, the left-right direction (the direction of the arrow cd ); and a locking slot 138b consecutively connected to the slow moving slot 138a and configured to extend rising from the root of said slow moving slot 138a, that is, one end of the closing direction 138a1, toward a closing side of the Sliding door.
[0123] The slow moving slot 138a is configured, as shown in Figure 10, to tilt with respect to the underside 40 of the pair of front and rear side wall plate elements 13a and 13b from one side. from full opening (the side of arrow d) to the side of full closing (the side of arrow c) and forms an angle 01. Note that angle 01 in the present embodiment is substantially 2.5 degrees. Also, the slow moving slot 138a is provided with a slot 138c at the end of the opening direction, said slot being further inclined, with a curved surface, from the end end of the slow moving slot 138a in the downward direction. Note that the curved surface of the slot at the end of the opening direction 138c is configured as a curved surface with a curvature substantially equivalent to that of a circle drawn with a radius R2 taking, as the center O2, a point away in the downward direction of the bottom side 40a of the pair of front and rear side wall plate elements 13a and 13b by the distance S1 and away from the right side 40b towards the left side 40c of the pair of front and rear side wall plate elements 13a and 13b by distance S2. In the present embodiment, S1 is 50.7 millimeters, S2 is 31.4 millimeters, and R2 is 61 millimeters.
[0124] [0071] Similarly, as shown in Fig. 10, the locking groove 138b is configured as a continuously arcuate curved surface from the opening direction end groove 138c. Note that the curved surface is configured as a curved surface with a curvature substantially equivalent to that of a circle drawn with a radius R3 and taking O2 as the center. In the present embodiment, the radius R3 is 65 millimeters.
[0125] [0072] The approach plate 12 includes the control plate element 12a and the connection element 12b, and the control plate element 12a comprises the contact face 12c which rests, inside the guide passage 20, on the outer peripheral surface of the disk element 14a integrated into the disk rolling element 14 to face the disk plate element 14a.
[0126] [0073] The contact face 12c of the approach plate 12 is configured, as shown in figure 11, as an inclined surface that rises from the full closing side towards the full opening side so as to configure the angle 02 with the upper end face 112b of the connecting element 12b. Note that angle 02 in this embodiment is 60 degrees.
[0127] [0074] Figure 12 shows some diagrams in which the operation of the security device 10 of the second embodiment above is described. Next, by means of figure 12, the operation of the security device 10 shown in figures 8 and 9 will be described. Similarly, in the security device 10 of this second embodiment 2, when the sliding door is moved towards the opening side complete, the approach plate 12 also moves to the full opening side in conjunction with the sliding door. Similarly, the disk rolling element 14 of the guide frame 11 rolls to the side of an end slot of the opening direction 138c of the limitation slot 38 by the inclination (angle 01) of the slow-moving slot 38a, rising from the fully open side (arrow side d shown in figure 3) to the fully closed side (arrow side c shown in figure 3), and stops inside the groove at the end of the opening address 138c.
[0128] [0075] Then, when the sliding door is moved from the fully open side to the fully closed side, the approach plate 12 also moves to the fully closed side together with the sliding door. When the approach plate 12 is moved to an intermediate position of the full closing side, as shown at (a) in FIG. 12, the contact face 12c of the approach plate 12 rests on the outer peripheral surface of the insert member. disc 14a integrated in disc rolling element 14.
[0129] When this contact is made, if the contact face 12c of the approach plate 12 rests slowly and normally on the disk element 14a of the disk rolling element 14 at low speed, the approach plate 12 slowly presses to the disc rolling element 14 in the closing direction (horizontal direction). The disc rolling element 14 then travels in conjunction with the approach plate 12 toward the full closing side as the shaft element 14b rolls into the slow moving slot 138a from the inside of the end slot. from the opening direction 138c and moves into the slow moving slot 138a towards the full closing side together with the approach plate 12. Also, as shown in (b) of Figure 12, when the shaft member 14b of the disk rolling member 14 reaches one end of the closing direction 138a2 of the slow moving slot 138a, the sliding door goes into the full closed state, completely covering the opening.
[0130] [0077] On the contrary, when the sliding door begins to close abruptly, the contact face 12c of the approach plate 12 collides with the outer peripheral surface of the disk element 14a of the disk rolling element 14, with a force default or higher than it. Subsequently, as with the vectors described in figure 7 (a), the rolling disk element 14 is moved by a force exerted on one side of the approach plate 12 with a vector resulting from a closing direction of the sliding door (substantially horizontal direction: Direction A) and a direction orthogonal to the inclined contact face 12c of the approach plate 12 (Direction B), towards a direction of said resulting vector (Direction C) and, as described in (c) in FIG. 12, the shaft member 14b travels from within the opening direction end slot 138c along the curved surface into the locking slot 138b. Also, the disk rolling element 14 is pushed by the approach plate 12, and moves past a full opening side end 138b1 to a stop element 138b2 of the locking groove 138b. When the shaft element 14b of the disk rolling element 14 moves to the stopper element 138b2, the contact between the stopper element 138b2 and the shaft element 14b causes the movement of the disk rolling element 14 to stop, and the plate approach 12 also stops in that position, together with the sliding door. That is, the sliding door is prevented from going to the fully closed state, and this stopping prevents a finger or other part of the body from being caught between the sliding door and a pillar or bar, and also prevents the sliding door from colliding with the pillar when opening, causing a great noise.
[0131] [0078] Also, in order to get the sliding door released from the stop state and goes back to the fully closed state, the approach plate 12 returns smoothly to the fully open side together with the sliding door. Next, the disc rolling element 14 loses the trapping force caused by the stop element 138b and the approach plate 12, falling from inside the locking slot 138b into the slow moving slot 138a to return into the slow motion slot 138a. Then, when the sliding door moves to the full closing side again, the disk rolling element 14 is again pushed by the approach plate 12 in a closing direction (horizontal direction), and moves together with the approach plate 12 toward the full closing side as the shaft member 14b rolls into the slow moving groove 138a. Subsequently, as shown in (b) of Fig. 12, the shaft element 14b of the disk rolling element 14 very soon reaches the end of the closing direction 138a2 of the slow moving slot 138a and when it reaches it, the sliding door goes into the fully closed state, completely covering the opening.
[0132] Likewise, when the sliding door is opened again, the sliding door moves towards the fully open side. Subsequently, following the displacement of the approach plate 12 towards the fully open side, the disk rolling element 14 also rolls down the inclination of the slow moving slot 138a to be returned to the slot at the end of the opening direction 138c . Subsequently, the device remains on hold until the sliding door closes again. Then, when it closes, the same movement is repeated.
[0133] [0080] Therefore, it also happens in the safety device 10 of this second embodiment that when the sliding door is normally closed slowly, it can be closed to the fully closed position. On the other hand, when the sliding door is abruptly closed, the shaft member 14b automatically moves from the inside of the opening direction end slot 138c into the locking slot 138b by the inclination of the contact face. 12c of the approach plate 12, and the disk rolling element 14 is very soon trapped between the stop element 138b2 of the locking groove 138b and the contact face 12c of the approach plate 12, thus inducing a locked state . Subsequently, the approach plate 12 can no longer be moved together with the sliding door towards the closing side, and in this way it is possible to prevent a finger or other part of the body from being inadvertently trapped during the door opening / closing operation. slider and prevent loud noise.
[0134] Also, after being locked, the lock is automatically released when the sliding door is gently turned back and the operation of moving to the complete closed state can be performed again, thus achieving simplification of the operation.
[0135] [0082] Furthermore, the shape of the locking groove 138b is configured as a curved surface with a curvature equivalent to that of a circle drawn with radius R3. Thus, when the disk rolling element 14 escapes towards the side of a locking slot 138b, the shaft element 14b moves into the locking slot 138b along said curved surface. This allows the movement to go smoothly.
[0136] [0083] Additionally, by changing the shape of the curved surface of the locking groove 138b and the shape of the slope of the contact face 12c of the approach plate 12, that is, the angle 02, the area Operation of the lock operation and other operations can be easily changed.
[0137] [0084] Figures 13 and 14 show a third embodiment of the security device 10 according to the present invention. Figure 13 is a side view of the security device 10 seen from the front, and Figure 14 is a side view of the security device 10 seen from the direction of a line CC of Figure 13. In the configuration of this third In embodiment, the structure of the constraint groove 38 of a guide frame 11 and the structure and shape of the slope (angle 02 and angle 04) of the contact faces 12c1 and 12c2 in the approach plate 12 are modified and the The rest of the structures are identical to those of Figures 1 to 7, which is why the same reference numbers have been assigned to the identical components, omitting redundant descriptions.
[0138] [0085] In Figure 13 and Figure 14, as in the first embodiment and in the second embodiment, the limiting grooves 38 with which the pair of front and rear side wall plate elements 13a and 13b have been provided respectively, they are configured such that they have substantially symmetrical shapes and can be hollowed out in the anterior-posterior direction.
[0139] [0086] Each of the limiting grooves 38 consists of: a slow moving groove 238a arranged to extend along a moving direction of the sliding door, that is, the left-right direction (the direction of the arrow CD); a locking slot 238b consecutively connected to the slow moving slot 238a; a neutral position slot 238c; a closing direction end slot 238d; and an opening direction end slot 238e.
[0140] The slow moving slot 238a is configured, as shown in Figure 15, to be inclined with respect to the underside 40a of the pair of front and rear side wall plate elements 13a and 13b from a side of full opening (the direction of arrow d shown in Fig. 3) towards the full closing side (the direction of arrow c shown in Fig. 3) and presents angle 01. Note that angle 01 in the present embodiment it is substantially two degrees. Also, the slow moving slot 238a has configured and connected at one end of the closing direction the slanting closing direction end slot 238d, with a retracted curved surface, from a terminating end of the moving slot. 238a and upward, and has configured and connected at one end of the closing direction the inclined neutral position slot 238c, with a projecting curved surface, from an end end of the slow moving slot 238a and into downward direction and the opening direction end slot 238e inclined, with a retracted curved surface, upward from the neutral position slot 238c. Note that the closing direction end slot 238d and the opening direction end slot 238e allow the disk rolling element 14 to escape in an upward direction (side of the upper wall element 13c) so that the approach 12 can access and pass through a bottom side of the disk rolling element 14. Therefore, although not shown, the toothed elements 28 (see FIG. 4) that allow the disk rolling element 14 to escape are configured on one side of the lower end of the vertical plate member 213c of the upper wall member 13c so as to correspond with the locking slot 38b, the closing direction end slot 238d, and the closing direction end slot. opening 238e.
[0141] In the same way as shown in figure 15, the locking slot 238b is configured continuously from the neutral position slot 238c so that it is inclined at an angle 03 with respect to the lower side 40a of the pair of front and rear side wall plate elements 13a and 13b in order to rise from the fully open side (arrow side d) to the fully closed side (arrow side c). Note that the angle 03 of the locking slot 238b is approximately 25.15 degrees in the present embodiment.
[0142] [0089] The approach plate 12 includes, as in the first and second embodiments, the control plate element 12a and the connection element 12b. The approach plate 12 is equipped with the contact faces 12c1 and 12c2 on the left and right sides of the control plate element 12a, respectively, and the contact faces touch the outer peripheral surface of the disk element 14a on the rolling element. disk 14 of the respective guide passages 20 so that they face disk element 14a. Note that the inclination (angle 02) of the contact face 12c1 is 45 degrees and that the inclination (angle 04) of the contact face 12c2 is 80 degrees in the present embodiment.
[0143] [0090] Figure 17 and Figure 18 show respective diagrams that describe the operation of the security device 10 of the third previous embodiment. Next, referring to Figures 17 and 18, the operation of the security device 10 shown in Figure 13 and in Figure 14 will be described. Also, in the security device 10 of this third embodiment, when the sliding door moves towards the full opening side, the approach plate 12 also moves towards the full opening side together with the sliding door. Similarly, the disk rolling element 14 of the guide frame 11 rolls to the side of an end slot of the opening direction 238e of the limitation slot 38 by inclination (angle 01) of the slow-moving slot 238a rising from the full opening side (side of arrow d shown in FIG. 3) to the full closing side (side of arrow c shown in FIG. 3), and stops inside the neutral position slot 238c.
[0144] [0091] Then when the sliding door moves from the full opening side to the full closing side, the approach plate 12 also moves to the full closing side together with the sliding door. When the approach plate 12 is moved to a middle position located on the full closing side, as shown in (a) of Figure 17, the contact face 12c1 of the approach plate 12 comes into contact with the surface. outer peripheral of the disk element 14a integrated in the rolling disk element 14.
[0145] [0092] When this contact occurs, if the contact face 12c1 of the approach plate 12 slowly and normally comes into contact with the disk element 14a of the disk rolling element 14 at low speed, the disk rolling element 14 is slowly pushed by the approach plate 12 towards a closing direction (horizontal direction). Next, the shaft member 14b rolls and enters into the slow moving slot 238a from inside the neutral position slot 238c and travels through the inside of the slow moving slot 238a towards the closing side. complete in conjunction with the approach plate 12. Also, upon reaching one end of the closing direction of the slow moving groove 238a, as shown in (b) of Figure 17, the shaft element 14b of the disk rolling element 14 rises into the closing direction end slot 238d to escape an upper end of the approach plate 12. This allows the approach plate 12 to move further in the complete closing direction in conjunction with the sliding door as shown in (c) of figure 17. Subsequently, the disk rolling element 14 will roll due to the inclination (angle 01) of the slow moving slot 238a towards an end slot of the opening direction 238e of the limiting slot 38 and is brought back to stop within the neutral position slot 238c.
[0146] On the contrary, when the sliding door begins to close with force, the contact face 12c1 of the approach plate 12 abruptly collides with the outer peripheral surface of the disk element 14a on the rolling disk element 14 with a force default or higher than it. Subsequently, as happened with the vectors described in figure 7 (a), the rolling disk element 14 is moved by a force exerted on one side of the approach plate 12 with a vector resulting from a closing direction of the sliding door (substantially horizontal direction: Direction A) and a direction orthogonal to the inclined contact face 12c1 of the approach plate 12 (Direction B), in the direction of said resulting vector (Direction C) and, as shown in (d) In FIG. 17, shaft member 14b moves from inside neutral position slot 238c into locking slot 238b. Also, the disk rolling element 14 is pushed by the approach plate 12, and moves towards a stop element 238b2 of the locking groove 238b. When the shaft element 14b of the rolling disk element 14 moves towards the stopper element 238b2, the contact between the stopper element 238b2 and the shaft element 14b causes the movement of the rolling disk element 14 to stop, and the plate approach 12 also stops in that position together with the sliding door. That is, the sliding door is prevented from going to the fully closed state for once, and this stop prevents a finger or other part of the body from being caught between the sliding door and a pillar or bar, and also prevents the sliding door collide with the pillar when opening, causing a great noise.
[0147] [0094] Also, to cause the sliding door to be released from the stopped state and to transition back to the fully closed state, the approach plate 12 is gently returned to the fully open side together with the sliding door. Next, the disc rolling element 14 loses the trapping force caused by the stop element 238b2 and the approach plate 12, falling from inside the locking slot 238b into the slow moving slot 238a to return to the interior of the slow moving groove 238a. Subsequently, when the sliding door moves back to the full closing side, the disk rolling element 14 is again pushed by the approach plate 12 in a closing direction (horizontal direction), and moves together with the approach plate 12 to the fully closed side as the shaft member 14b rolls into the slow moving slot 238a. Next, as shown in (b) of Fig. 17, the shaft element 14b of the disk rolling element 14 very soon reaches the end of the closing direction of the slow-moving groove 238a. Subsequently, after the operation of (b) in Figure 17, the approach plate 12 and the sliding door are allowed to move towards the full closing side.
[0148] [0095] Likewise, when the sliding door is opened again, the sliding door moves towards the fully open side. Subsequently, the approach plate 12 is also moved towards the fully open side together with the sliding door. When the approach plate 12 is moved to a central position on the fully open side, as shown in (a) in Figure 18, the contact face 12c2 of the approach plate 12 comes into contact with the outer peripheral surface of the disk element 14a of the disk rolling element 14. Also, the shaft element 14b of the rolling element of disk 14 reaches the end of the closing direction of the slow motion slot 238a. Subsequently, the rolling disk element 14 is displaced by a force exerted on the side of an approach plate 12 with a vector resulting from an opening direction of the sliding door (substantially horizontal direction) and a direction orthogonal to the contact face inclined 12c2 of the approach plate 12, towards a direction of said resulting vector and, as shown in (b) in figure 18, ascends into the slot of the end of the opening direction 238e to escape from the plate approach 12. As shown at (c) in FIG. 18, this allows approach plate 12 to move further towards a full opening direction in conjunction with the sliding door. Next, the disk rolling element 14 rolls by inclination of the opening direction end slot 238e towards a closing direction end side and stops again within the neutral position slot 238c.
[0149] [0096] Therefore, in the safety device 10 of this third embodiment, the approach plate 12 can change to the position of the guide frame 11 to move to the full closing side and the full opening side. This allows the security device 10 to be in a free position in which the sliding door can pass.
[0150] [0097] Also, in the security device 10 of the third embodiment, when the sliding door is slowly closed normally, it can be closed to the fully closed position. On the other hand, when the sliding door is closed with force, the axis member 14b automatically moves from the neutral position slot 238c into the locking slot 238b by the slope of the contact face 12c1 of the plate. approach 12, and the disk rolling element 14 is very soon trapped between the stop element 238b2 of the locking groove 238b and the contact face 12c1 of the approach plate 12, thereby causing a locking state. Subsequently, the approach plate 12 is prevented from moving together with the sliding door further towards the closing side, and thus it is possible to prevent a finger or other part of the body from being inadvertently caught during the opening / closing operation of the sliding door and to prevent a great noise from being produced.
[0151] [0098] Also, after a locking operation, the lock is automatically released when the sliding door returns smoothly, and the operation of placing it in the fully closed state can be performed again, thus achieving the simplification of the operation.
[0152] Furthermore, the shape of the locking groove 238b is configured as the inclined surface. Thus, when the disk rolling element 14 escapes to the side of a lock slot 238b, the shaft element 14b moves into the lock slot 238b along the inclined surface. This allows the movement to go smoothly.
[0153] [0100] Additionally, by changing the shape of the inclined surface of the locking groove 238b and the shape of the slope of the contact face 12c1 of the approach plate 12, that is, the shapes of angle 03 and angle 02 , the operating area of the locking operation and other operations can be changed very easily.
[0154] [0101] Note that, although the case of a sliding door has been described in each of the previous embodiments, this sliding door includes a ^{sho ji} paper sliding door ^, a ^{fu su ma} paper sliding door ^, a window and other elements of these types.
[0155] [0102] Likewise, the locking slots 38b, 138b, and 238b and the disk rolling element 14 are locked when the sliding door is abruptly moved towards the full closing side, but the safety device 10 can be fixed by reversing this orientation, and the sliding door can lock when it is abruptly moved to a full opening side.
[0156] [0103] Likewise, although it has been indicated in each of the previously described embodiments that the safety device 10 is configured to supervise at all times the function of whether the sliding door opens or closes abruptly when it opens or closes When this supervision of the safety device 10 is not required, the supervision carried out by the safety device can be canceled and performed again when necessary. The mechanism of Monitoring switching can be configured, for example, as shown in Figure 19, providing, to each limiting slot 38; the slow moving slot 38a configured to extend along a direction of movement of the sliding door, that is, the left-right direction (the direction of the arrow cd); locking slot 38b consecutively connected to slow moving slot 38a; a neutral position slot 38c; an opening direction end slot 38e; a disk rolling element removal groove 38f; and a locking groove 38g, and disposing the contact faces 12c1 and 12c2 that are in contact on the surface of the outer periphery of the disk element 14a on the disk rolling element 14 inside the guide passage 20 so as that the contact faces face the disk element 14a.
[0157] [0104] Regarding the removal groove of the disc rolling element 38f and the locking groove 38g, when the rolling disc element 14 is located in this removal groove of the disc rolling element 38f or in the slot of lock 38g, said disk rolling element 14 is placed in a state of retracting to a position higher than the upper surface of the approach plate 12 passing through the interior of the guide passage 20. And even in the case that the approach plate 12 passes through the inside of the guide passage 20, the approach plate 12 does not come into contact with the disk rolling element 14. Therefore, if the supervision carried out by the safety device 10 were not necessary, with the rolling element of disc 14 located within the removal groove of the disc rolling element 38f, the monitoring performed by the safety device 10 may be invalidated. Furthermore, as the disc rolling element moves from the disc rolling element removal slot 38f into the locking slot 38g, the locking slot 38g retracts below the disc rolling element removal slot. 38f and the shaft element 14b of the disk rolling element 14 falls into this removal groove of the disk rolling element 38f to be locked in said position. This allows a state to exist in which the monitoring performed by the security device 10 is canceled to be reliably locked out.
[0158] [0105] On the other hand, when the safety device 10 is required, the shaft element 14b integrated in the rolling disk element 14 moves from the inside from the locking groove 38g toward the retracting groove of the disc rolling element 38f, and is returned from inside the retracting groove of the disc rolling element 38f through the opening direction end slot 38e into the neutral position slot 38c, thus allowing the safety device 10 to be returned to a valid state of use.
[0159] [0106] In addition to what has been indicated above, the present invention can be modified in various ways, provided that said modifications do not depart from the spirit of the present invention, and it goes without saying that the present invention covers said modifications.
