Window shade with bi-directionally operating actuating elements
[15] The invention relates to a blind having an actuating member operating in both directions.
[16] It is known to use blinds to control the light entering the interior of a vehicle. Such blinds generally have a winding shaft, which is arranged invisible from the outside and on which the edge of the window shade web is fixed. The blind web is subjected to initial stress in the direction of winding the blind web by a spring drive. The blind web extends through slits provided in a window sill, upper roof edge or rear window shelf.
[17] Pull rods that are guided at the ends of the one or more guide rails are provided to maintain the tension of the blind web. If two guide rails are used, the pull rod is guided at both ends, and in general, because the car window is not an exact rectangle, it extends or shortens like a telescope during its retraction and extension.
[18] Displacement of the pull rods of the guide rods against the action of the spring drive is achieved with the aid of a linear-shaped flexible actuating member. They are designed similar to Bowden cables and consist of cylindrical cores or cylindrical core members, which support ribs extending spirally from the outside thereof. A kind of toothed rack is formed in this way, which has teeth all around. The outer diameter of the actuating member is selected such that the actuating member can be guided substantially without buckling in the guide groove of the guide rail without coming out of the slit of the guide groove.
[19] In the devices known to date, the individual ends of the actuating member and the guide body of the pull rod running in the guide groove are flush connected. This planar connection can only deliver pressure.
[20] A gear motor is provided for extension and retraction, the output shaft of which supports a gear wheel that meshes with the actuating member. Displacement of the actuating member causes the blind web to be pulled out of the winding shaft and the blind web to extend. During this process, the blind web is kept taut by the spring drive.
[21] The contraction is achieved by changing the direction of rotation, and the electric motor pulls the operating member out of the guide groove so that the pull rod can move in the direction toward the winding axis.
[22] In order to make the space requirement of the take-up shaft as small as possible, the take-up shaft is manufactured to have a small outer diameter. Therefore, a large number of turns are required to completely wind the blind web. Even when the spring stroke uses a relatively long spring drive, the winding end torque is quite different from the winding torque at the start. In addition to this, when the blind is completely wound, the effective diameter, ie the lever arm is large. If the blind web has proper tension when fully deployed, the force to pull back the pull rod relatively weakens towards the end of the contraction motion.
[23] In an undesirable state, the pull rod may come to a stop before it is fully retracted. The small clamping force of the guide bodies of the guide rail helps to hold it. As the width changes, the guide bodies must be subjected to initial stresses to ensure that no rocking occurs, because these bodies are subjected to significant friction in the guide rails.
[24] Based on the above, it is an object of the present invention to make blinds for automobiles which can transmit the pulling and pushing forces of the pull rod's actuating members.
[25] According to the invention this object is achieved by a blind having the features of claim 1.
[26] In the new blind, the blind web is wound by a winding shaft and preferably by a spring drive on the winding shaft. The pull rod device is attached to the edge of the blind web away from the take-up shaft, from which the guide body moves in one or more guide grooves of the guide rail. The guide body and the actuating member each have a coupling halves, which half permit one or more couplings. Within the intended scope of the present invention, this connection may be a snap-in connection that is closed once operated.
[27] An important advantage of this device is that the pull rod device and the operating member can be installed completely independently of one another in the process of mounting the blinds according to the invention. According to the design, only after the installation is completed automatically during the first operation or after the installation is completed by a separate assembly step, the coupling between the guide bodies with respect to the operation member is completed or bite together.
[28] However, the coupling can also be designed to be connected and disconnected during operation as many times as desired. This embodiment preferably does not match the retracted end position of the actuating member to the structural end position of the pull rod device. Such a condition may arise if the actuating member needs to simultaneously perform other functions such as opening and closing of a flap for the slit from which the blind web is pulled through it. In other examples, there is the possibility of operating another blind web that is wound around a separate winding shaft using the same operating member. Such automotive blinds are known from German patent DE 100 57 763 A and incorporated herein by reference.
[29] A coupling that is only connected once is a snap-in connection, for example a device for coupling several times consists of two coupling halves, which in a broad sense are hook-shaped.
[30] In order to achieve perfect connection and disconnection, one of the coupling halves can only be displaced longitudinally in the guide rail and the other half can only be moved transversely in addition.
[31] A crank mechanism is provided to engage and disengage this coupling in the correct position during operation. The crank mechanism may consist of a control shoulder, which is for example a rim of an opening additionally formed in the guide groove.
[32] The force required to engage and disengage the coupling halves can be obtained from the driving force. For this purpose, the surfaces on the coupling halves that can be joined together are suitably designed to extend obliquely. Fixed control surfaces may be used for release. The last mentioned embodiment prevents the force from continuing in the release direction to increase friction and wear on the guide rails.
[33] If the coupling is made to engage and disengage as many times as desired during operation, the actuating member can also be used to perform other functions after release by overtravel. To this end, the other end of the actuation member is usefully provided in the corresponding coupling half, so that the two ends of the actuation member are equally implemented.
[34] The spring motor of the take-up shaft can be provided relatively very weakly due to the special pull- and push-resistant coupling with the actuating member.
[35] Further improvements of the invention are the subject matter of the dependent claims. In this regard, combinations of features for which a particular embodiment is not indicated should also be considered to be claimed.

[37] 1 schematically shows a rear view of a passenger car 1 with a roof 2, a trunk 3, and two C-shaped pillars 4, 5. A rear window opening 6 is located between the two C-shaped pillars 4, 5, bounded by a rear roof edge 7 at the top and a window ledge at the bottom. Bounded by The rear window 9 is placed in the rear window opening and glued, for example in a known manner, using a window rubber strip.
[38] A shelf 10 extending horizontally between the lower window edge 8 and the rear seat back (not shown) is located at the inner front of the rear windshield 9 inside the passenger car. A straight outlet slit 11 extends from the shelf.
[39] The outlet slit 11 is part of the rear blind 12, the basic structure of which is very schematically illustrated in FIG. 2.
[40] The rear blind 12 has a blind web 13, which is shown in an expanded state in FIG. 1. It has a trapezoidal shape to cover the rear window whose overall shape is trapezoidal.
[41] As shown in FIG. 2, the winding shaft 16 is rotatably installed under the shelf 10. One edge of the blind web 13 is fixed on the take-up shaft 16. The other edge away from the winding shaft 16 is connected with the pull rod device 17.
[42] The take-up shaft 16 is subjected to initial tension in the direction of winding the blind web 13 by the spring motor 18 in the take-up shaft 16.
[43] Two guide members 19 are shown of the pull rod device 17, which can be displaced substantially telescopically. The telescopically displaceable guide member 19 runs on two guide rails 20, 21, which extend into the vehicle on the other side of the lateral edges of the window opening 6 and are not visible from the outside. .
[44] The operating member 22 runs inside the two guide rails 20, 21. The guide rails 20, 21 lead to guide tubes 23, 24 under the shelf, through which the guide rails 20, 21 are connected to the gears 26 of the gear motor 27. The actuating member 22 extends through the guide rails 20, 21 and the guide tubes 23, 24.
[45] The actuating member 22 has a linear flexibility similar to a Bowden cable with a cylindrical core member 29 as shown in an enlarged view in FIG. 3 and with ribs 30 extending spirally outward of the member. It is absent. A kind of toothed rack with inclined teeth is formed. With the help of the ribs 30, the operating member 22 mates with the output gear wheel 31 shown in dashed lines, which is fixed so as not to rotate relatively on the output shaft 32 of the gear motor 27. It is installed.
[46] The two actuating members 22 extend tangentially past the gear wheel 31 on the opposite side. Thereby they move in synchronization in the opposite direction.
[47] The design of the two guide rails 20, 21 follows the enlarged view of FIG. 3. Each guide rail is a kind of tube with a guide groove 33, which is open outwardly on one side as a guide slit 34. The guide rail forms a back 35 at the opposite side 34. The fixing flange formed of one part on the guide rails 20 and 21 is not shown in the drawings for the sake of clarity.
[48] Each operating member 22 is connected to the pull rod 17 by a pull-and-push resistance coupling 36. The pull rod device 17 comprises a guide member 19 which has a cylindrical shank 37 which can be telescopically displaced into the intermediate part of the pull rod device. At their ends, the adjacent individual guide rails 20, 21, shank 37 are turned into thin necks 38, which are guided through the slit 34 into the guide grooves 33. Extrude At the inner end, the necked member 38 supports the guide body 39, the cross-sectional shape of the body mating with the cross section of the guide groove 33. The guide body 39 can displace in the longitudinal direction in the guide groove 33, but cannot rotate around an axis extending parallel to the longitudinal axis of the shank 37.
[49] The coupling 36 consists of two coupling halves 41, 42. The coupling half 42 is a plate-shaped member, which is pivotably mounted on the guide body 39. To this end, the guide body 39 is provided with transverse slits (not shown) on the side facing the actuating member 22, so that a forked mouth is formed. Coupling half 42 lies in this forked mouth. The coupling half is held pivotably by a hinged bolt 43 which extends past the corresponding hole of the guide body 39 and the coupling half 42. The axis of the hinge formed by the bolt 43 extends at right angles to the longitudinal axis of the shank 37.
[50] At the free end away from the guide body 39, the coupling half 42 is designed in the shape of a hook. The mouth of the hook is open in the direction towards the slit 34. In particular, each end of the coupling half 42 consists of the following faces: The first face 44 extends parallel to the longitudinal axis of the shank 37. It starts at the side of the coupling half 42 next to the slit 34 and extends about one third into the guide groove 33. The face 45 is adjacent the face 44 and extends at an angle of about 45 ° in the direction towards the rear wall 35 or the actuating member 22. At the end adjacent to the rear wall 35, the face 45 changes to a face extending in the direction towards the slit 34. Finally, face 47 adjoins face 46 and reaches obliquely to rear wall 35. However, faces 44, 45, 46, 47 extend vertically on the same plane.
[51] The coupling half 41 is a kind of bushing, which is clamped in place on the core member 28. The tongue 48 is crimped on the outer circumferential side of the coupling half 41 and extends into the slit 34 to prevent the coupling half from rotating.
[52] At the end remote from the actuating member 22, the coupling half 41 is designed to complement the coupling half 42. It is located parallel to the opposite side of the face 44 with the front end of the coupling half positioned farthest in engagement. The front face 49 changes to a face 51 extending parallel to the face 45. Face 52 is adjacent to face 51 extending parallel to face 46, and finally face 53 is implemented parallel to face 47. Faces 49, 51, 52, 53 extend perpendicular to the ground of the drawing.
[53] The transverse dimension of the tongue-shaped coupling half 42 is such that its side face 54 extends a short distance from a portion of the guide groove 33 adjacent the rear face 35. Due to this arrangement, the coupling half 42 cannot be released from the hooked connection with the coupling half 41 because the play between the flank 54 and the wall of the guide groove 33 is not possible. ) Is less than the lift required to release the hook.
[54] The function of the illustrated device is as follows:
[55] Assume that coupling 36 is shown in FIG. 3. As the blind 12 extends further, the gear motor 27 is pushed forward on the two guide rails 20, 21 in the direction toward which the actuating members 22 face the upper ends of the individual guide rails 20, 21. It works. In this process, a pushing force or pressure is transmitted from the coupling half 41 to the coupling half 42. This pushing force causes the two sides 44, 49 to meet horizontally so that no tilting force can be transmitted to the coupling half 42, and if there is a tilting force it should be done well, face 46. 47 is a force that allows the tip between 47 and 49 to enter deeper into the inlet between the faces 52 and 53, since the two faces 44 and 49 are only along the sides of the hinged bolt 43, for example. This is because pushing force is generated. The pushing force exerted by the actuating member 22 acts directly on the pull rod device 17, causing the blind web 13 of other material to be released from the take-up shaft 16 against the action of the spring motor 18.
[56] To retract the blind 12, the motor 27 operates in the opposite direction of rotation. As a result, the operation member 22 moves backward from the guide rails 20 and 21. The pull rod device 17 follows the same as the actuation member 22 retracts, because the pulling force to wind the blind web 13 continues to be acted upon by the spring motor 18.
[57] If the force exerted on the pull rod device 17 by the spring motor 18 is not sufficient, the individual actuating members transmit a pulling force to the pull rod device. This force transmission is provided by coupling halves 41, 42 which are joined together by a hook of coupling 36. In order to transmit the pulling force, a suitable pulling force is transmitted through the faces 46, 52, so that each end of the pull rod device 17 is pushed to follow the retraction of the actuating member 22. Since the two faces 46 and 52 are oriented obliquely with respect to the longitudinal extension of the guide rails 20 and 21, a component of a force is formed which tries to separate the two coupling halves 41 and 42 from each other. However, it cannot be separated, because the coupling half 42 is supported by the side surface 54 on the wall of the guide groove 33 and the coupling half 41 is next to the slit 34. It is supported on another wall.
[58] Release of the coupling 36 is possible only in a position in which the slit-shaped opening 7 in the path of the guide rails 20, 21 is provided in the rear wall 35 as shown in FIG. 4. The force acting to separate, effective on the faces 46, 52 in the transverse direction with respect to the longitudinal extension of the guide rail 21, causes the upper coupling half 42 to move away from the slit 34 as shown. By pivoting, the two upper coupling halves 41 and 42 can be disengaged.
[59] From this point on, the actuating member 22 continues its running alone, and the pull rod device 17 stops at this time.
[60] Thus, the operating member 22 can perform a stroke that moves farther than the pull rod device 17. To this end, the other of the actuating members 22 to perform other functions or operations, for example to close the flap (not shown) against the slit or to unfold the second blind web as described in the patent application mentioned above. Ends can be used.
[61] The coupling 36 is again engaged when the actuating member 22 moves upward from that shown in FIG. 4. During this process, face 49 comes into contact with the edges that end in the direction that face 44 faces slit 34. This forms a pushing force and further forms a torque around the hinged bolt 43. Two actions take place together in the pull rod device to be lifted up, and after the shoulder 58 of the opening 57 located in the direction of movement is coupled with the coupling half 42 out of the opening 57 with respect to FIG. Pivot the upper coupling half counterclockwise again until it returns to the configuration according to FIG.
[62] In the embodiment described above, the faces 46, 52 of the coupling halves 41, 42 have a force of release until the actuating member 22 pulls the guide member 19 of the pull rod device 17. It is designed to keep working. Depending on the choice of angles of the faces, how the closing connection works, and how large the force that the actuating member 22 needs to pull, a somewhat greater separation force is created, which is the rear wall 35 of the guide rail. Tends to push the coupling half 42 against the. If this action is not desired, the embodiment according to FIGS. 5 and 6 can be selected.
[63] The structure of the embodiment according to FIGS. 5 and 6 is similar to that of the embodiment described above, so that the members corresponding to each other functionally use the same reference numerals. Accordingly, the following description is limited only to substantial differences.
[64] According to the embodiment of FIG. 5, the coupling half 42 is hinged directly to the guide member 19 with the aid of the hinged bolt 43. The guide body 39 previously used as a connection between the guide member 19 and the coupling half 42 is omitted.
[65] The coupling half 42 is plate-shaped and has a hook-shaped configuration that opens in a direction toward the slit 34 at its end facing the actuating member 22.
[66] In the pushing direction, the inlet of the hook is bounded by a face 61 extending through the actuating member 28 at right angles to the actuation axis. In the direction toward the slit side of the guide rails 20, 21, the face 61 changes to the inclined surface 62, which protrudes from the guide slit 34. At the tip 63 located next to the slit 34, the face 63 is in contact with the face 64, which face 64 extends in the direction towards the guide member 19. The exact configuration can be seen in FIG.
[67] At the inwardly positioned end, ie the end adjacent to the backside 35, the face 61 changes to a face 65 extending parallel to the back face 35. A right angle is formed between these faces 61 and 65. Face 65 terminates at face 66, which extends parallel to face 61, but is only about half the length.
[68] The face 67 also extends parallel to the face 65, starts at face 66 and ends at face 68, and is acute in the direction towards the actuating member 28 or the back face 35.
[69] Coupling half 41 is secured firmly and immovably in a manner complementary as before. The coupling half 41 also forms a hook, the inlet of which is bounded by faces 69, 71, 72. The face 69 extends at right angles to the longitudinal axis of the guide rails 20, 21, the face 71 extends in the longitudinal direction of the guide rail, and the face 72 extends at an acute angle. The hook inlet is bounded in this way, opening in the direction towards the rear face 35 of the guide rails 20, 21. Coupling halves 41 are bounded to the outside by faces 73, 74, 75, 76. Among them, face 73 is adjacent to face 69 and extends parallel to face 71. Face 74 is parallel to and at a distance from face 69 starting at face 73. The face 75 abuts the face 74 at a bend in the position facing the slit 34 and extends at an acute angle with respect to the longitudinal axis of the guide rails 20, 21. Finally, the face 76 adjacent the face 75 is parallel to the back face 35 and extends out of the slit 34.
[70] Finally, a stop 78 having an obliquely extending control surface 79 is provided for controlling the release process. In the manner described below, the control surface 79 acts in conjunction with the surface 64. The stationary control surface 79 has a face 64 also located at the height of the slit-shaped opening 57. The stop 78 is attached to the vehicle body next to the slit 34.
[71] The function of the device according to FIGS. 5, 6 is as follows:
[72] First, as shown in FIG. 5, it is assumed that the coupling 36 is coupled. In this state, the face 66 is horizontal and smoothly contacts the face 69 when the pull rod device 17 is pulled by the actuating member 28. Since the two faces 66, 69 extend perpendicular to the longitudinal axis of the guide rails 20, 21, no component of force is formed by the faces which tends to separate the faces 66, 69. Only the force acting on the coupling half 42 tangentially to the hinged bolt 43 generates a small torque in the clockwise direction.
[73] However, if the pull rod device 17 is to be pulled against the front end or front face 74 by a spring drive that is placed on the winding shaft and tends to wind the blind web 13, the face 74 ) Lies horizontally with respect to the face 61 of the coupling half 42. These two faces that engage each other extend at right angles to the longitudinal axis of the guide rails 20, 21, whereby no separation force component is formed. In this state, the faces 68 and 72 are spaced apart from each other. No force is thereby created to pivot the coupling half 42.
[74] During contraction, when the motion sharpens, the coupling halves 41 pull the coupling halves 42 in the direction towards the blind axis, and the faces 66 and 69 of the hooks contact each other as shown. The coupling half 42 is used at the same time as a guide member for the guide member 19, and for this reason the coupling half extends outwards through the slit 34 as shown. Unlike the previous embodiment, the hinge by the hinged bolt 43 is located outside the guide rails 20, 21.
[75] During the movement of the pull rod device 17, ie the guide member 19, the coupling half 41 moves further past the stop 78, and the tip 63 of the coupling half 41 is moved. It hits the control surface 79. The special arrangement of the control surface 79 shown in FIG. 5 causes the coupling half 42 to pivot in the counterclockwise direction with respect to what is shown. The coupling halves 41 securely fixed to the actuating member 28 cannot follow this deflection movement. For this reason, the two coupling halves 41 and 42 are separated from each other, resulting in a state according to FIG. 6. As shown, during the pivoting movement, the coupling half 42 exits back through the elongated slit 57. The faces 66, 69 are disengaged so that together with the coupling half 41, the actuating member 28 can continue to move straight in the direction of travel without further accompanying the coupling half 42.
[76] Otherwise, the design of the coupling halves 42 and the position of the faces are determined such that the coupling halves 41, 42 cannot be disengaged from each other anywhere except the elongated opening 57.
[77] However, if the blind web 13 is to be extended, the coupling half 41 on the right side of FIG. 6 approaches the coupling half 42 stationary at the stop 78. During movement, the edge between the faces 74 and 75 abuts the face 62, which face component tends to rotate the coupling half 42 clockwise around the hinged bolt 43. Inclined to form At the same time, the pull rod device 17 together with the coupling half 42 is pushed away from the stop 78 so that the control surface 79 of the stop 78 pivots on the coupling half 42. You no longer interfere with your workout.
[78] The pivoting movement of the coupling half 42 ends with the face 74 lying horizontally with respect to the face 61. These faces extend at right angles to the longitudinal extension of the guide rails 20, 21, so that virtually no pivoting force component occurs due to the shape of the faces. Only a small force component is left, so that the vector of force that occurs during the pulling or pushing of the coupling halves 41, 42 extends from the hinged bolt 43 by a predetermined radial distance.
[79] These residual force components are shown by the hinged bolts 43 as guide rails 20 and 21 as shown in the preceding figures, ie the axis of action of the force between the two coupling halves 41 and 42. application of the force, can be avoided. Finally, it will be appreciated that the pairs of faces 61, 74; 66, 69 can be aligned to form a force component that extends correspondingly inclined and that cancels the torque around the hinged bolt 43.
[80] Embodiments as shown in the preceding figures show couplings that can be engaged and disengaged as often as desired, with the coupling 36 passing through the shoulder 58 in each direction.
[81] If the actuation member 22 does not need to overrun, but if a subsequent return to the initial or rest position of the pull rod device 17 is required, the coupling shown schematically in FIG. 7 can be used. have. This coupling is a snap-in connection which, once operably engaged, cannot be released later.
[82] At the end away from the core member 28, the lower coupling half 41 has two hooks 80, 81, which are spaced apart from each other by the slit 82. The guide member 39 is a ring shape having a hole 83, which extends in a funnel shape in the direction toward the coupling half 41. Thus, the guide member 39 is also another coupling half corresponding to the coupling half 42 of the previous embodiment at the same time.
[83] The coupling 36 according to FIG. 7 can cause the pull rod device to be automatically arranged on the guide rails 20, 21, and to allow the operating member 22 to pass back and forth independently of the guide rails 20, 21. Can be. As soon as the two members are placed in the correct manner, the guide member 39 is pushed past the hooks 80 and 81 in the direction towards the actuating member 22, which hooks are thereby pressed. When the pushing is finished, the hooks return by their elastic force to their initial position and are caught behind the guide member 39. In this way, the coupling 36 is engaged and is able to transmit the pulling and pushing force from the actuating member 22 to the pull rod device 17.
[84] The vehicle blind has a pull rod device, which can be reliably moved in a direction away from the take-up shaft and in a direction toward the take-up shaft by an operating member running through the guide rail. For this purpose, a reliably coupling is provided between the pull rod device and the individual actuating members.
