    [0004] OBJECT OF THE INVENTION
    [0006] The present invention provides an automatic closing and opening device for doors. More in particular, the present invention discloses a more secure closing device that allows the automatic closing of the door, without the need to pass the key, significantly reducing the force necessary to exert on the door so that the automatic closing is executed, thus maximizing safety and reliability. Additionally, the device can be opened by key or by remote electromagnet excitation.
    [0008] BACKGROUND OF THE INVENTION
    [0010] Some automatic door closing devices, which do not have the need to pass the key to execute the closing, are known in the state of the art. The devices known to the applicant are based on taking advantage of the movement of a handle when closing the door and using said movement to force springs so that when the door is closed, said springs release the bolts that are inserted into a strike. or closing plate and thus immobilizes the door. This has the drawback that the latch needs to make more effort to retract and requires a greater effort to close the door, which is why a greater blow of the door against the frame is necessary when closing. An example of this system is that disclosed by the European patent application EP0280845 A2 "Lock with rocker clutch with elastic accumulation".
    [0012] There are other embodiments that provide an automatic closure by means of a hook that rotates and is inserted into the strike, and can be opened by electromechanical means. However, they have great drawbacks in their manufacture due to their great complexity, since they require a great variety of components and parts. An example of these automatic closing systems is German patent application DE 2014104139.
    [0014] Another type of automatic closing devices describes fixing the door from the frame strike, without resolving the opening from the door but from the frame, so they are not valid for entrance doors, but for other applications such as anti-panic systems.
    [0015] This type of anti-panic device is disclosed, for example, in patent applications WO2017149544 or British patent GB1399058.
    [0017] DESCRIPTION OF THE INVENTION
    [0019] The present invention aims to solve some of the problems mentioned in the state of the art.
    [0021] More specifically, the present invention discloses a high-security anti-theft closing and opening device for a door, which executes the closing automatically, without the need to pass a key, exerting minimal effort on the door without the need for large knocks or knocks. stresses on the door frame when closing, thus maximizing safety and reliability.
    [0023] More in particular, the present invention discloses an automatic opening and closing device for doors, comprising a strike and at least one lock, where the strike comprises a closure plate connected to the frame of a door, and the lock understands:
    [0024] - a box,
    [0025] - an anchoring piece fixed to the box rotatably with respect to an anchoring axis comprising a housing, an elongated pivot portion, and a guide located in the portion distal to the anchoring axis, said guide presenting a stop,
    [0026] - a latch connected to the box in a rotatable manner with respect to a latch axis, comprising a portion projecting to the box and a portion housed in the box, where the portion housed is housed in the housing of the handle that serves as a support point of said latch, and the protruding portion interacts with the strike to open or close the door,
    [0027] - an anchor spring fixed to the box and attached to the anchor piece to exert a restoring force that opposes the rotation of the anchor piece when it is pushed by the cam,
    [0028] - a latch spring that exerts a restoring force that opposes the latch turning when it is pushed by the cam,
    [0029] - a stem comprising a head projecting to the box, a base adjacent to the head, said base comprises a spring and is fixed to the box, the stem also comprises a cover attached to said stem, where the cover is in direct contact with the stop of the unlocking piece, where the head with the cover has longitudinal freedom of movement with respect to the base fixed to the box and the contact with the stop and the cover resist the restoring force of the anchor spring.
    [0031] When the door opens, the stem is pushed outwards by the spring and as a consequence, the cover, which is integral with the stem, moves pushing the anchor piece outwards, thus releasing the anchoring piece from the latch, in such a way that it is configured to allow said latch to rise when it comes into contact with the striker again when the door closes.
    [0033] When the door is closed, the head comes into contact with the closing plate attached to the door frame and as a consequence moves inside the box pushing the spring, said spring pushes the lid, releasing by means of the covers the anchor part of the stop, allowing the spring to exert the restoring force on the anchor piece, moving the support point of the anchor piece on the latch, finally allowing the spring to exert the restoring force and turn the latch closing the door.
    [0035] Note that overcoming the spring pressure of the anchor piece does not require great efforts, but the simple contact of the stem head with the door frame will start a simple mechanism where the pressure of the anchor piece spring is released and consequently the it exerts the pressure of the latch spring to close the door, without great efforts or blows on the frame, by means of great ease of operation and assembly.
    [0037] Likewise, it should be noted that once closed, the latch will have the force of the latch spring and again the anchoring of the anchoring piece, so it will have two alternative security pieces opposing the opening turn of the latch, so if it breaks some of the springs would follow the automatic closing device closed with an important anti-theft security
    [0039] Preferably, in order to open the door, an actuating element will be necessary that pushes the pivot of the anchoring piece and subsequently pushes the end of the latch inside the box, consequently releasing the latch from the support that represents the housing in the anchoring piece, to later provide a torque to overcome the force exerted by the latch spring.
    [0040] More preferably, to perform the opening, at least one unlocking cam connected to the box rotatably with respect to an axis, and designed to rotate by means of an actuating element to push the pivot of the unlocking piece and subsequently the latch, can be used. , opening the door.
    [0042] The unlocking cam may comprise a first cam portion intended to be actuated by an actuating element to make it rotate, a second cam portion having a first contact area to contact the pivot of the anchor piece and rotate the piece. anchoring, and a second contact area to contact the area housed in the latch and rotate the latch.
    [0044] It can also comprise at least one spring fixed to the box and joined to the unlocking cam to exert a restoring force that opposes the rotation of the cam, and return it to an initial rest position.
    [0046] Note that when the latch has lowered to its closed position, the springs of the anchoring cams pull them, making them rotate to their initial or "vertical" position, anchoring the lock and preventing the latch from opening.
    [0048] Preferably the box may comprise inside a cylinder body comprising a body and a socket rotatably housed inside the body and has a housing for inserting a key rotatably into the housing in a first opening rotation direction, said spindle comprising a cam cylinder that protrudes outside the body, to rotate jointly with the joint when the key rotates inside the housing in a first opening rotation direction. Said cylinder cam would be the actuating element to rotate the unlocking cam by turning a mechanical key.
    [0050] Note that when activating the door opening by turning the key in the first direction of rotation, the cylinder cam pushes the first portion of the unlocking cam, rotating the cam in the opposite direction until, first, push the contact area of the part of anchoring by making it pivot, moving the support point on the latch, releasing it and subsequently the rotation of the cam pushes the latch overcoming the restoring force of the latch spring and as a consequence it pivots in the first opening rotation direction, rising up to the stop defined by the geometry of the box, allowing how consequently opening the door. Subsequently, the cam spring exerts the restoring force on the cam, returning to an initial position at rest.
    [0052] More preferably, and in a combinable way with the mechanical opening with the cylinder, the device can have an electronic actuating element. This can be an electromagnet or a coil as an actuating element of the unlocking cam, by means of a shaft driven by electrical excitation with a remote control. In this case, the thrust of the shaft will actuate the mechanism explained above by means of the mechanical key.
    [0054] Preferably, the striker consists of a closure plate attached to the frame comprising a plurality of holes, an L-shaped stop configured to contact the sloping distal end of the latch, and a projecting flange.
    [0056] Said strike fixed to the frame can have an elongated longitudinal distance with respect to the frame with a plurality of holes intended to close a door with a plurality of latches from multiple locks arranged vertically.
    [0058] Alternatively, the strike may be of the hinge type, with a U-shape, more specifically, the strike may further comprise:
    [0059] - a contact plate intended to come into contact with the door comprising two fins that extend in a transverse direction to the contact plate defining a rear fin and a front fin.
    [0060] - a rod connecting the contact plate with the closing plate and fixed to the frame, configured to allow a relative hinge-type movement of the contact plate with the closing plate fixed to the frame.
    [0061] - a striker spring inserted into the rod and configured to exert a joining force between the contact plate and the closing plate, said spring allows a separation between the plates of approximately 5-30 °, and the joining force of the spring The striker plate is intended to keep the contact plate retracted against the closure plate attached to the frame. Preferably said separation is 20 °.
    [0063] Thus, when the door is in an open position, the strike spring keeps the closing plate and the contact plate attached to each other to allow the latch to enter an opening in the plate when the door is closed. contact by raising the handle.
    [0064] When the door continues the closing movement, it comes into contact with the rear wing of the door, exerting pressure on the contact plate, and consequently overcoming the force of the striker spring, forcing the contact plate to move against the side surface. or transverse door.
    [0066] As a consequence, the contact plate moves the head of the lock and said head moves inside, triggering the closing of the lock explained above until the latch spring turns the latch to a lower position, closing the lock and consequently the door. attached to the contact plate.
    [0068] Finally, when the door is closed, the distal section of the L-shaped latch fixes the contact plate in the closed position, overcoming the force of the strike spring, and the two wings are projected on the inside and outside of the door. door, allowing greater security against possible theft, making access to the interior difficult to force the latch.
    [0070] When the door is opened by mechanical means or by electromagnet, the above-mentioned opening is activated, the latch rises and the distal L-section of the latch stops holding the contact plate, allowing the door to open.
    [0072] Note that consequently the joining force exerted by the strike spring will favor the opening of the door by exerting a restoring force that tries to join the contact plate with the closing plate, as a consequence facilitating a comfortable opening of the door.
    [0074] Preferably, the striker comprises a striker stop connected to the lock plate in a rotatable manner and located between the contact plate and the lock plate, specifically above the latch when the lock is closed with the latch turned in a lower position.
    [0076] Additionally, the contact plate may have a stop opening, shaped by the transverse geometry of the stop and said opening located in a position higher than the strike stop.
    [0078] Consequently, when the lock is opened, the latch pushes the strike stop, said stop when rotating the contact plate enters through the stop opening, allowing free movement of the contact plate and therefore the strike spring exerts the unopposed joining force of the closing stop or the distal L-section of the latch.
    [0080] Note that when the door is closed, said closing stop provides additional security, since if the handle is forced or even cut with a saw, the stop will keep the strike in the closed position, consequently, blocking a possible forced opening, since it prevents the union of the closing plate with the contact plate.
    [0082] The hinge-type strike may also have a movable stop (42) with a spring and said stop attached to a plate. The movable stop can move longitudinally on a cylinder located on the closing plate fixed to the frame so that if it is inserted towards the inside of the hinge-type strike it is located just above the strike stop. In such a way that the movable stop is rotated and the protruding end of the plate is anchored on the movable stop of the strike, preventing it from moving back due to the force of the spring.
    [0084] Note that being in this position prevents the door from being opened from the outside even with the key, since by preventing the lifting of the strike stop it also prevents the lifting of the latch and the door cannot be opened, neither from the outside nor from inside, even if the key is used. If the stop is turned until the plate is released from the strike stop, the movable stop is moved by the spring force to a position in which the strike stop is free and therefore the door can be opened both from the outside and from the inside.
    [0086] Note that this is an added security for people who want complete security when they are inside the house, since it prevents entry from the outside if the strike is not unbolted.
    [0088] In a combinable way with any of the above, the closing plate fixed to the frame can have an elongated longitudinal distance with respect to the frame with a plurality of holes intended to close a door with a plurality of latches from multiple locks arranged vertically.
    [0089] The device can simultaneously close all locks by a linked, or "multipoint" mechanism. Preferably, each unlocking cam can have a rigidly coupled gear that rotates integral with said unlocking cam, moving a transmission during the turning of the key or that of the electromagnet for closing, communicating the same movement to a plurality of lock boxes. lock arranged vertically, by means of movement strips.
    [0091] Preferably, the multipoint lock can have a different configuration in relation to the unlocking stem, which, while being similar and performing the same function explained above, in this case the stem spring is inside said stem and pushes the stem both towards the outside of the lock as a locking piece of an inward gear rack. Said rack transmission meshes with a gear arranged on the same unlocking camshaft and transmits the movement to the different locks placed.
    [0093] This rack transmission has a slotted area where a protruding area of the transmission locking piece is inserted when the door is closed due to the fact that this locking piece is pushed by the stem spring into said groove preventing movement transmission with a rack and therefore the forcing of the lock if some of the transmission elements between the different locks were to be activated.
    [0095] To open the lock, it is done by turning the cylinder spindle by means of the key. Initially, when the spindle is rotated, it carries a cam, here we have represented it outside the spindle, but it can also be done preferably inside the cylinder to facilitate the placement of the cylinder in the lock. Said cam, with the rotation of the spindle, moves a locking piece, taking it out of the slot and allowing, as the spindle continues to rotate, that when the cylinder cam comes into contact with the unlocking cams, the lock is opened as described above. , as the rack transmission has been unlocked.
    [0097] More preferably, and in a combinable way with the mechanical opening with the cylinder, the device can have an electronic actuating element. These can be two electromagnets or coils as actuating element of the unclamping cam and the locking piece by means of a shaft driven by electrical excitation with a remote control. In this case, the thrust of the electromagnet shaft will act first, unlocking the transmission with rack and then the electromagnet for the movement of the unlocking cams will actuate the mechanism explained above by means of the mechanical key.

    [0120] PREFERRED EMBODIMENT OF THE INVENTION
    [0122] Figure 1 shows a front view of the inside of a box (1) of the lock (1a) in a first embodiment of the device for the automatic closing of the door, where the interior of the box (1) of a lock can be clearly seen (1a) when in the closed state, said box (1) comprises a cylinder (2) with a cam (30) intended as an actuating element for the opening mechanism, by turning a mechanical key.
    [0124] Furthermore, said box comprises an anchoring piece (11) fixed to the box (1) rotatably with respect to an anchoring axis (5) comprising a housing (18), an elongated pivot portion (20), and a guide (21 ) located in the distal portion with respect to the anchoring axis (5), said guide (21) presenting a stop (19).
    [0126] The box (1) also contains a latch (7) connected to the box (1) in a rotatable manner with respect to a latch axis (4), comprising a protruding portion (71) to the box (1) and a portion housed (72) in the box (1), where the housed portion (72) is housed in the housing (18) of the anchoring piece (11) and where said housing (18) serves as a point of support and blocking of the latch ( 7), the projecting portion (71) has in a distal section a projection (73) transverse and inclined with respect to the box (1) -
    [0128] The box (1) further comprises a disengagement cam (10) connected to the box (1) in a rotary manner with respect to an axis (9) destined to rotate by actuation of the cam (30) by the rotation of a mechanical key, said cam comprises a first cam portion (100) intended to be actuated by the key to make it turn, a second cam portion (101) presenting a first contact area (102) to contact the pivot (20 ) of the anchoring piece and rotating the anchoring piece (11), and a second contact area (103) to contact the area housed in the latch (72) and rotating the latch (7).
    [0129] Figure 1 also shows a spring (17) fixed to the box (1) and attached to the anchor piece (11) to exert a restoring force that opposes the rotation of the anchor piece (11) when it is pushed by the cam (10), and a spring (8) that exerts a restoring force that opposes the rotation of the latch when it is pushed by the cam (10), and a spring (16) fixed to the box (1) and attached to the release cam (10) to exert a restoring force that opposes the rotation of the release cam (10).
    [0131] Thus, as shown in figure 2, when the door is opened by turning the key in the cylinder (2) in a first direction of rotation, the cam (30) pushes the first portion (100) of the locking cam. unlocking (10) by rotating the cam in the opposite direction until, first, push the pivot (20) of the anchoring piece (11), making it pivot, moving the support point of the housing (18) on the latch (7), and then the Rotation of the unlocking cam (11) pushes the housed area (72) of the latch (7) overcoming the restoring force of the latch spring (8) and as a consequence it pivots in the first opening rotation direction, rising up to the stop defined by the geometry of the box (1), thus allowing the door to open.
    [0133] Once open, the cam spring (16) exerts the restoring force on the unlocking cam (10), returning to an initial position at rest, whereby the anchoring piece (11) returns to its initial vertical position.
    [0135] Figure 3 shows a view of the strike (2a) of the previous embodiment, where a closure plate (20) is shown intended to be fixed to the door frame, said closure plate (20) comprises a plurality of holes (25), an L-shaped stop (26) configured to contact the sloped distal end of the latch (72), and a projecting flange (27).
    [0137] Additionally, figure 1 shows a stem (22) comprising a head (13) projecting to the box (1), a base (12) adjacent to the head (13), said base (12) comprises a spring (15) and is fixed to the box (1), the stem (22) also comprises a cover (14), where the cover (14) is in direct contact with the stop (19) of the unlocking piece (11), when The lock (1a) is closed or open but not when it is in the opening process, so that said contact of the stop (19) and the cover (14) resist the restoring force of the spring (17), keeping the anchoring piece ( 11) at rest and vertical. When it is in the opening process, the head (13) comes out of the lock and therefore releases the latch (7) from the anchor piece (11) by means of the force exerted on the area (19) by the cover ( 14), allowing said latch to rise.
    [0138] When the door is closed, the stop (26) of the closing plate (20) comes into contact with the inclined face of the latch (7) forcing it to rise. The head (13) and the cover (14) have freedom of longitudinal movement with respect to the base (12) fixed to the box (1), therefore, the head (13) then comes into contact with the projecting flange (27) of the closing plate (20) attached to the door frame and as a consequence it moves into the box (1) pushing the spring (12) which in turn pushes the cover (14), releasing the piece anchor (11) of the stop (14), and as a consequence allowing the spring (17) to exert the restoring force on the anchor piece (11), moving the support point of the latch (7) on the anchor (11), finally allowing the spring (8) to exert the restoring force and turn the latch, closing the door.
    [0140] Note, that. Once the lock (1a) is closed, it has two independent security systems, on the one hand, the latch spring (8) and, as an auxiliary system, the housing (18) of the anchoring piece (11) in a vertical position acting as a point of support and preventing a forced opening of the latch (7).
    [0142] Figure 4 shows a front view of the interior of the lock box in a second embodiment where the lock further comprises an electronic actuator element composed of an electromagnet and an actuator shaft electronically excited by said electromagnet.
    [0144] Figure 5 shows a perspective view of a third embodiment of the device, comprising the lock described above and comprising an alternative U-type strike (2b) with hinge-type movement. The third embodiment shown by figure 5 comprises a striker (2b) comprising a contact plate (31) intended to come into contact with the door and wherein said contact plate (31) comprises two wings (32,33) that are They extend transversely to the contact plate defining a rear fin (33) and a front fin (32). Said contact plate also has a slot (43) intended to allow the head (13) of the stem (15) of the lock to penetrate.
    [0146] Figure 6 shows a rod (34) joining the contact plate (31) with the closure plate (35) configured to allow a relative hinge-type movement of the contact plate (31) with the closure plate (35 ) attached to the frame.
    [0147] The striker (2b) further comprises a striker spring (36) inserted into the rod (34) and configured to exert a joining force between the contact plate (31) and the closing plate (35), said spring (36) allows a separation between the plates (35,31) of substantially 20 ° and the binding force of the strike spring (36) is intended to keep said plates together by means of a restoring force exerted by said spring (36).
    [0149] Therefore, when the door is in an open position, the strike spring (36) keeps the closing plate (35) and the contact plate (31) joined together, to allow that, when the door is closed, the The latch (71) can enter an opening (37) that the contact plate (31) presents by raising the latch (71) by means of the inclination that it presents in its distal portion (73).
    [0151] When the door continues the closing movement, it comes into contact with the rear flap (33) of the door, exerting pressure on the contact plate (31), and as a consequence the force of the strike spring (36) overcomes, forcing the plate contact (31) to move against the transverse or lateral surface of the door.
    [0153] As a consequence, the contact plate moves the head of the lock and said head (13) moves inside, triggering the closing of the lock explained above until the restoring force of the spring (8) of the latch turns the latch (71) towards a lower position closing the lock.
    [0155] Finally, when the door is closed, the distal section of the latch (73) that has an L shape fixes the contact plate (31) in the closed position, overcoming the force of the strike spring (36), and the two wings (32 , 33) are projected on the inside and outside of the door respectively, allowing greater security against possible theft, making access to the interior difficult to force the latch.
    [0157] When the door is opened by mechanical means or by electromagnet, the aforementioned opening is activated, the latch (7) rises and the L-shaped distal section (72) of the latch stops holding the contact plate (31), allowing the door to open.
    [0158] Note that consequently the binding force exerted by the strike spring (36) will favor the opening by pushing the contact plate (31) against the closing plate (35) facilitating a comfortable opening.
    [0160] Figure 6 shows a side view of the described embodiment, where it is shown that the strike (1b) comprises a strike stop (38) connected to the closure plate (35) in a rotatable manner and located between the contact plate ( 31) and the closing plate (35), specifically above the latch (71) when the lock is closed with the latch (71) turned in a lower position.
    [0162] Figure 6 also shows that the contact plate (31) has a stop opening (37), which defines the transverse geometry of the stop (38) and said opening (37) located in a position higher than the strike stop (38) .
    [0164] Consequently, when the lock is opened, the latch (71) pushes the strike stop (38), said strike stop (38) enters through the stop opening (37), allowing the free movement of the place. of contact (31) and consequently the strike spring (36) exerts the joining force without the opposition exerted before by the closing stop before being pushed by the latch, nor by the hold exerted by the distal section (72) L-shaped handle (7), consequently allowing the door to be opened comfortably.
    [0166] Note that when the door is closed, said closing stop (38) exerts additional security, since, if the distal portion that protrudes from the latch (7) is forced or even cut with a saw, the stop ( 38) of the striker will keep the striker (1b) in the closed position, blocking a possible forced opening.
    [0168] In the preferred embodiment of the hinge-type strike (2b) described above, the strike further comprises a movable stop (42) with a spring (41) and said stop (42) attached to a plate (40). The movable stop (42) intended to move longitudinally on a cylinder located on the closing plate fixed to the frame so that if it is inserted towards the inside of the hinge-type strike, it is located just above the strike stop (38). So that the movable stop (42) is rotated and the protruding end of the plate (40) is anchored on the movable stop (42) of the strike, preventing it from moving back due to the force of the spring (41).
    [0169] Note that being in this position prevents the door from being opened from the outside even with the key, since by preventing the lifting of the strike stop it also prevents the lifting of the latch and the door cannot be opened, neither from the outside nor from inside, even if the key is used. If the stop (42) is turned until the plate (40) is disengaged from the strike stop (38), the movable stop (42) is moved by the force of the spring to a position in which the strike stop is free and therefore both the door can be opened both from the outside and from the inside.
    [0171] Note that this is an added security for people who want complete security when they are inside the house, since it prevents entry from the outside if the strike is not unbolted.
    [0173] Figure 7 and Figure 8 show a fourth embodiment of the device that allows all the locks to be simultaneously closed by a linked or "multipoint" mechanism. Said embodiment presents a second rear unlocking cam that has a coupled gear (201), which rotates in solidarity with said second unlocking cam, moving a transmission (200) during the turning of the key or the electromagnet for closing and communicating the same movement to a plurality of vertically arranged lock boxes, by transmission (200).
    [0175] Figure 9 shows a fifth embodiment, more specifically of the "multipoint" type, which comprises a different configuration in relation to the unlocking rod (13), which, although similar and performing the same function explained above, in this case the spring (207 ) is on the inside of the stem and pushes both the stem out of the lock and a locking piece (202) inward. Said rack transmission (200) meshes with a gear (201) arranged on the same axis of the unlocking cams and transmits the movement to different locks arranged vertically.
    [0177] This multipoint embodiment, with a rack transmission, has a slotted area (206) where a projecting area of the transmission locking piece (202) is inserted when the door is closed due to the fact that this locking piece (202) is pushed by the spring (207) into said slot (206) preventing the movement of the transmission with rack (200) and therefore the forcing of the lock if some of the transmission elements between the different locks.
    [0178] To open the lock, the cylinder spindle (3) is turned by means of the key. According to the present embodiment, the cylinder (3) comprises a cam (203), which rotates integrally, said cam (203) with the rotation of the cylinder (3) displaces the locking piece (202), taking it out of the slot (206) and allowing, as the rotation continues, that when the cam (203) contacts the unlocking cams, the opening of the lock is performed as described above, since the transmission with rack has been unlocked.
    [0180] In said preferred embodiment, the device further comprises two electromagnets (204 and 205) as actuating element of the unlocking cam and of the locking piece (206) by means of a shaft operated by electrical excitation with a remote control. In this case, the thrust of the electromagnet shaft (206) will first act by unlocking the rack transmission and then the electromagnet for the movement of the unlocking cams (204) will actuate the mechanism previously described by means of the mechanical key.
