Description

Background Art

[0001] Devices are known for moving movable furniture parts, in particular devices for guiding the movement of movable furniture parts, which are fastened, for example, to a guide or to the relevant piece of furniture. The known devices usually comprise a force accumulator, by means of which the movable furniture part is supported during an opening and / or closing movement relative to the furniture body. In order to eject the furniture part from the closed position in the opening direction, the device is first triggered from a ready position with the force accumulator charged, so that the force accumulator is activated. Summary of the invention

[0002] The object of the invention is to improve a device for the assisted movement of a movable furniture part with the aid of a force accumulator, in particular with regard to the reliable setting of a ready position of the device.

[0003] This object is achieved by the independent claims.

[0004] Advantageous and advantageous variants of the invention are indicated in the dependent claims.

[0005] The invention is based on a device for moving a furniture part in an opening direction relative to a furniture body of the furniture, wherein the furniture part is movable in the opening direction and in a closing direction opposite to the opening direction via a guide. The device is in particular an ejection device, for example a drawer or door or flap ejection device, which has a touch-lock function for a drawer or furniture flap. The guide is preferably a known rail guide, which is designed as a partial or complete extension, or a flap or door fitting. The device can be functionally coupled to or include an automatic retraction mechanism for gently or softly retracting the furniture part or drawer, door or flap or door into the closed position of the drawer or flap or door in a damped, force-assisted manner.

[0006] The device comprises a force accumulator which can be charged and an ejector which can be driven in an opening direction under the action of the force accumulator which is unloaded, wherein the force accumulator can be locked in the charged state so that the furniture part can be moved in an opening direction from a closed position on the furniture body by means of a device mounted on the furniture after unlocking of the charged force accumulator, wherein the ejector is kinematically coupled to the furniture part, wherein the force accumulator can be charged as the ejector is moved back in the closing direction, wherein a synchronizing mechanism of the device is provided which can be coupled to a synchronizing mechanism of another corresponding device arranged on the furniture for moving the furniture part in the opening direction in order to synchronize the unlocking of the charged force accumulator of the device. The synchronizing mechanism particularly relates to a latching function on a relatively wide furniture part on which two identical ejection devices spaced apart in the width direction are present. The two devices work together when ejecting the furniture part, wherein their force accumulators jointly provide a cumulative total ejection force acting on the furniture part. Failure to trigger both devices together results in that the force of only one of the two force accumulators is used for ejection. Particularly in the case of fully loaded furniture parts, this can mean that the furniture parts are not ejected.

[0007] The core of the present invention is that the synchronization mechanism of the device can be reversibly shifted in the opening direction and the closing direction, wherein, after the charged force accumulator is unlocked, the synchronization mechanism is moved from the starting position in the opening direction to the shifting position, so that the synchronization component used for synchronization can be moved, wherein, in order to return the synchronization mechanism to the starting position, a stop member is provided, and a movement coupling can be established between the ejector and the synchronization mechanism in the closing direction by means of these stops, so that when the force accumulator is charged again, the synchronization mechanism is driven from the shifting position or from a position between the shifting position and the starting position in the closing direction to the starting position.

[0008] Thus, if the synchronization mechanism has not yet reached the starting position, the synchronization mechanism is advantageously returned to the starting position reliably and forcibly controlled by the mechanical stop function. In this case, the ejector moves in the closing direction and loads the force accumulator. This is the case when the furniture part is closed. Here, when the furniture part is closed, the ejector also moves in the closing direction, for example mechanically and firmly coupled to the furniture part being closed, and thus also loads the force accumulator. Preferably, the part of the device that is coupled to the ejector movement, for example the ejector when closing the furniture part, drives the synchronization mechanism, for example, to the starting position. It may also be the case that when a pulling force acts on the synchronization part in the closing direction, the synchronization mechanism only needs to be driven briefly by the stopper, and this pulling force is then sufficient to cause the remaining movement to reach the starting position. Therefore, for the next push-out movement, the furniture part is closed, the force accumulator is loaded, and the synchronization mechanism is in its starting position necessary for synchronization.

[0009] The invention solves in particular the problem that, for example due to component tolerances, material changes or other influences, the movement of the synchronization mechanism from the shifted position back to the starting position does not occur or is not completed despite the presence of a retraction force, for example caused by a return element such as a return spring. This can occur, for example, when there is an excessive friction effect that acts on the movement of the synchronization mechanism in a braking or holding manner. For the release impulse for the movement, usually only relatively weak forces are required, for example by driving an ejector, in order to drive the synchronization mechanism from its rest position, for example caused by static friction, thereby bringing the synchronization mechanism to the starting position.

[0010] Advantageously, a reset element is provided, which acts on the synchronizing mechanism and provides a reset force in order to bring the synchronizing mechanism into the starting position. The reset element provides a reset force on the synchronizing mechanism in the direction of the starting position, which is preferably permanently established. The reset element is preferably a reset force accumulator or a tension element, such as a tension spring, for example a helical spring, which acts on the synchronizing mechanism in a prestressed or pulling manner in the closing direction. Since the reset force is designed to be relatively weak relative to the force accumulator for the ejection movement of the furniture part, since this reset force must be overcome by the force accumulator during the ejection process in order to eject the furniture part and therefore a force component that is as small as possible should be formed to counteract the ejection force, it often or spontaneously occurs that the reset force is not sufficient or not always sufficient to pull the synchronizing mechanism back into the starting position, for example due to friction forces on the synchronizing mechanism. Therefore, at the latest when the furniture part and thus the ejector are moved in the closing direction, the synchronizing mechanism is forcibly brought into the starting position by means of the stop. Usually, after the first pressure impulse, for example, an ejector acts on the synchronization mechanism by means of a stop, thereby overcoming in particular the effect of static friction, so that the restoring force provided by the restoring element is then sufficient to move the synchronization mechanism into the starting position solely through the action of the restoring element. Otherwise, the stop would act accordingly, for example even at the same time producing a braking effect on the movement of the synchronization mechanism into the starting position, even if the frictional resistance is too high.

[0011] Preferably, a permanent connection is established between the reset element and the synchronization mechanism. Thus, in addition to the stop, the reset element also acts when the furniture part is closed in order to bring the synchronization mechanism to the starting position. For example, an effective reset force can be transmitted to the synchronization mechanism.

[0012] The reset element is advantageously designed to apply a tensile force to the synchronization mechanism in the closing direction. This allows a force to be reliably applied to reset the synchronization mechanism, for example using a slightly prestressed helical tension spring. The level of the tensile force is lower than the level of the ejection force of the force accumulator acting in the opening direction, preferably several times lower. The tensile force preferably acts permanently on the synchronization mechanism in the closing direction.

[0013] Another advantage is that the stop element comprises a stop surface on the synchronization mechanism, which contacts the mating stop surface when the ejector moves in the closing direction. By means of the stop surfaces that are appropriately matched to each other, a planar contact can be achieved when the force accumulator is loaded, for mechanically coupling or reliably driving the synchronization mechanism in the closing direction. The stop surface and the mating stop surface are preferably perpendicular to the movement direction of the synchronization mechanism.

[0014] It is also advantageous if the stop has a projection on the outer contour of the moving part, which can be coupled to the ejector. The projection can be designed in a simple and space-saving manner. The projection has, for example, a stop surface that is transverse and perpendicular to the movement direction of the synchronization mechanism.

[0015] An advantageous variant of the invention is that the force accumulator acts on an ejector which is movable in the closing direction and in the opening direction and which, after the charged force accumulator is unlocked, drives the ejector in the opening direction. The ejector is thus moved according to the distance required for charging and unloading the force accumulator. In contrast, the ejector can be moved, in particular, over a greater movement distance in the opening direction, in order, for example, to move the furniture part further in the opening direction after the force accumulator has been unloaded. A special ejector-force accumulator can act on the ejector, for example, in order to exert a tensile force on the ejector which acts in the opening direction.

[0016] The ejector acts in particular between the ejector and the furniture component.

[0017] Advantageously, there is at least temporary movement coupling between the ejector and the pusher in the closing direction for charging the force accumulator and in the opening direction for force-assisted ejection of the furniture part in the opening direction.

[0018] When the stopper is configured between the ejector and the synchronization mechanism, another advantageous modification is produced. Like this, the time point of the start and end of the path length in the closing direction and / or the stopper that acts can be variably set or determined.

[0019] Typically or preferably, the force accumulator, i.e. the force accumulator for ejection, has a bearing point located on the device and a bearing point acting on the ejector. In addition to the stop on the synchronization mechanism, further stops are preferably present on the ejector. The stop on the ejector is preferably present on the end section of the ejector, viewed in the longitudinal direction of the ejector or in the direction of movement of the ejector, which end section faces the fixed bearing point of the force accumulator.

[0020] Alternatively, a stop is configured between the ejector and the synchronization mechanism.

[0021] Another advantageous modification is that, for synchronization, an elongated connecting part is connected to the synchronization mechanism, so that the movement of the synchronization mechanism in the opening direction causes the rotational movement of the connecting part in the first rotational direction. The linear movement of the synchronization mechanism is converted into the rotational movement of the connecting part by a suitable transmission element. The connecting part is preferably connected to one of the two synchronization mechanisms at its opposite ends in a kinematically coupled manner. Here, the connecting part spans the interval between two devices on the furniture. In this way, when the ejector moves, in order to unlock the loaded force accumulator, the preferably linear movement of the synchronization mechanism (which the synchronization mechanism performs) can be reliably transmitted to the corresponding synchronization mechanism on another or other device corresponding to the device on the furniture part through the rotating connecting part. The rotation of the connecting part causes the linear movement of the other synchronization mechanism in the opening direction, and thus causes the locking of the other force accumulator on the other device to be released at the same time. Then the two force accumulators together and synchronously generate their force action on the furniture part in the opening direction. As a result, the furniture part is reliably ejected under the cumulative force action of the two force accumulators. By means of the inherently rigid connecting element, the synchronous movement transmission eliminates the possibility of a triggering latch when pressing on a furniture part in the triggering or access area of ​​a single device, which would otherwise usually mean that another device is not triggered or another force accumulator is not unlocked.

[0022] The movement of the synchronization mechanism in the closing direction causes the rotational movement of the connecting part in the second rotational direction, such as when resetting the synchronization mechanism in the closing direction. This also advantageously synchronizes the force action of the reset part or the entrained movement performed by the synchronization slide through the stop.

[0023] Advantageously, the device has a touch-lock function for unlocking the charged force accumulator. This is a proven and user-friendly design. Advantageously, no gripping means for pulling on the outside of the furniture part is required to open the furniture part, because with the touch-lock function, pressing the furniture part from the outside is sufficient to trigger and unlock the ejection force accumulator and subsequently close the furniture.

[0024] The invention is also realized as a piece of furniture having a furniture carcass and a furniture part which is movable relative to the furniture carcass via a guide, wherein a device according to one of the above designs is present.

[0025] If the guide element is designed as an articulated element, for example a flap fitting or a door hinge, the piece of furniture is a piece of drawer furniture or a piece of furniture with a pivotable flap or door. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] exist Figure 1 5 shows a piece of furniture 50 having a box-shaped furniture body 51 and a drawer 53, which is movably guided by a guide 52. The drawer 53 includes a drawer bottom 54, a drawer front 55, two opposite side walls 56 and a drawer rear wall 57.

[0045] For guiding the drawer 53, there are two guides 52 with the same function between each side wall 56 of the drawer 53 and the associated body side wall 58. Two identical devices 1, 2 according to the invention (shown in dashed lines) are arranged on the bottom surface of the drawer bottom 54, which are used together and synchronously to move or push out the furniture part designed as a drawer 53 in the opening direction M1.

[0046] The device 1 is used to eject the drawer 53 from the closed position relative to the furniture carcass 51 in the opening direction M1 of the drawer 53 with force assistance along a partial distance of the opening movement of the drawer 53. The drawer 53 can be movably arranged on the furniture carcass 51 in the opening direction M1 and in the opposite closing direction M2 by means of a guide 52, for example two identical partial or full extensions. The device 1 can be arranged alternatively on the furniture carcass 51 or on the guide 52 of the furniture 50.

[0047] The same applies to the device 2 , and in the following reference will be made in particular to the device 1 .

[0048] The device includes a base plate 3, a force unit 4, a latch member 5, an ejector 6 and a force accumulator 7 (see Figure 2) as a basic main component. A guide rail 8 is constructed in the base plate 3. A recess 9 for receiving a moving part 10 is also provided in the base plate 3, on which the force accumulator 7 preferably acts. The moving part 10 can also be called an ejector. The force accumulator 7 includes at least exactly one coil spring 11, preferably two coil springs 11, 12 that can be used separately, which are fixed to the moving part 10 at one end. The other ends of the coil springs 11, 12 are advantageously connected to a support portion 13, wherein the length of the tensioned coil springs 11, 12 and thus their preload can be adjusted by an operating section 14. An elastic rod 15 is arranged on the moving part 10, which is preferably guided in a heart-shaped curve 16 formed in the base plate 3 with a bent end section. In addition, the elastic rod 15 can be moved along a guide slot 17 of the ejector 6. During the movement of the elastic rod 15 along the guide slot 17 in the ejector 6 and / or the heart-shaped curve 16 in the base plate 3, the synchronization mechanism designed as a synchronization plate 18 moves together. The synchronization plate 18 can be moved linearly in the directions P1 and P2. The synchronization plate 18 is connected to the base plate 3 via a spring 19. When the synchronization plate 18 moves, the synchronization element 18a is in a rotation D1, the direction of rotation depending on the movement of the synchronization plate 18 in the direction P1 or P2. The synchronization element 18a is in a rotation D1. Figure 15-17 The other end (not shown) is connected to another device 2 or to the synchronization plate 18 of the device 2 accordingly.

[0049] The base plate 3 is covered by a cover element 20 , wherein the cover element 20 forms a matching plate which corresponds almost to the base plate 3 , so that the interior of the device 1 is closed on both sides and on the peripheral narrow edges, wherein individual areas are open to the outside.

[0050] The cover part 20 has a control cover 21, which is formed in two parts or is formed integrally with each other. The control cover 21 preferably has another heart-shaped curve (not shown), which in the assembled state preferably provides a guide corresponding to the heart-shaped curve 16 for the other angled end of the elastic rod 15 in the base plate 3. This makes it possible to reliably guide the elastic rod ends of the elastic rod 15 on both sides.

[0051] The guide rail 8 is designed in the base plate 3 in order to move the latching member 5 along the guide rail 8. The guide rail 8 preferably has two separately designed guide rails 8 in the width direction of the base plate, which is oriented perpendicularly to the opening and closing movement of the ejector 6. The guide rail 8 can be divided into two guide areas 22, 23, preferably into exactly two guide areas. The first guide area 22 is constructed in the base plate 3 to be sunken compared to the plane side of the ejector 6. The second guide area 23 preferably extends in the opening direction P1 and the closing direction P2 of the ejector 6. The direction P1 is related to the direction M1, and the direction P2 is related to the direction M2.

[0052] The two guide regions 22 , 23 oriented at an angle to one another together form, for example, an L-shape, wherein the longer leg forms the second guide region 23 and the shorter leg forms the first guide region 22 .

[0053] exist Figure 3 The receiving portion for the second end of the force unit 4 in the base plate 3 can be seen. The first end of the force unit 4 is connected to the connecting section 24 of the latch member 5 (see Figure 4 ). The latching member 5 also has a guide mechanism 25, which is preferably permanently movable in the second guide area 23 of the guide rail 8. The guide mechanism 25 protrudes at the latching member 5 and is preferably in the form of a cylinder or a bolt. Preferably, there are guide mechanisms 25 on both sides of the latching member 5, which can be moved along the guide rail 8 spaced apart in the width direction. Advantageously, the guide mechanism 25 can be supported and moved along the second guide area 23 of the guide rail 8. The latching member 5 also has a guide part 26, which is moved from the first guide area 22 into the second guide area 23 during the opening movement of the ejector 6. As a result, the hook section 27 of the latching member 5, which is located above the guide part 26 in the direction of the ejector 6, can be pivoted in the direction of the ejector 6. The latching member 5 also has a hook profile 28 that can interact with the ejector 6. The hook profile 28 is preferably oriented transversely to the opening and closing direction of the ejector 6.

[0054] The ejector 6 has a recess 29 on the bottom surface facing the substrate 3 (see Figure 5 ). The recess 29 is preferably groove-shaped, wherein the longitudinal extension L of the recess 29 is oriented in the opening and closing direction of the ejector 6. The connecting section 24 of the latching member 5 is preferably received in the recess 29. The recess 29 has a surface with an edge profile 30 formed in the width direction and the height, which can be coupled and decoupled with the hook profile 28 of the latching member 5.

[0055] A stop member 31 is constructed on the ejector 6, which cooperates with the drawer 53 or the drawer rail of the guide 52. After the loaded force accumulator 7 that remains locked is unlocked, the ejector 6 is moved during the opening movement of the movable part 10, and the ejector moves the drawer 53 in the opening direction P1 by means of the stop member 31, using the force of the loaded force unit 4 and / or the force accumulator 7. During the closing movement P2, a section of the drawer 53 or the drawer rail is pressed against the stop member 31 of the ejector 6, thereby loading the movable part 10 or the ejector, and thus loading the force accumulator 7 and the force unit 4 acting on the ejector.

[0056] exist Figure 6 In the figure, the device is shown in the closed position. Figures 6 to 8 The cover member 20 is not shown in the figure. In addition, the control cover 21 is Figure 6 Not shown. Figure 7 , 8 , 10, 11, 13 and 14, in order to better observe the arrangement of the latching member 5 in the guide rail 8, only the ejector 6 and the latching member 5 are partially shown.

[0057] according to Figures 6 to 8 It can be seen that the latching member 5 is covered from above by the ejector 6 in the closed position. The connecting section 24 of the latching member 5 is received in the recess 29 of the ejector 6, wherein the edge contour 30 of the recess 29 does not interact with the hook contour 28 of the latching member 5. The guide part 26 of the latching member 5 in the closed position is in the first guide area 22, so that the force unit 4 is maximally tensioned. The guide mechanism 25 is supported on the guide rail 8 in the second guide area 23.

[0058] The elastic rod 15 is arranged in the arcuate section of the heart-shaped curve portion 16, wherein the elastic rod 15 cannot move in the opening direction P1 because the synchronization plate 18 blocks this movement (see Figure 6 ). The device 1 has reached the zero position and the drawer 53 rests on the furniture body 51 in the closed position.

[0059] The drawer 53 is intentionally opened or ejected by the user from the outside. The user uses the touch-lock function and pushes the drawer 53 or the drawer front 55 of the drawer 53 inward in the closing direction M2, thereby causing the ejector 6 to move along the closing direction P2 with the moving part 10. Through the moving part 10, the elastic rod 15 is also moved in the closing direction P2, whereby the elastic rod 15 is no longer blocked by the synchronous plate 18. The spring end surrounds the end face of the synchronous plate 18, which can now move in the opening direction P1. The accumulator 7 is therefore unloaded, and the elastic rod 15 moves in the opening direction P1 along the heart-shaped curve portion and the side wings on the synchronous plate 18. When the elastic rod 15 moves in the opening direction P1, the synchronous plate 18 and the ejector 6 also move in the opening direction P1. The drawer 53 is driven or ejected. Then it reaches the first open position (see Fig. 9 ). In the first open position, the accumulator 7 is unloaded.

[0060] exist Fig.10 and Fig.11, the guide part 26 of the latching member 5 is still in the first guide area 22 of the guide rail 8, so the hook section 27 has not yet deflected in the direction of the ejector 6. By making the edge contour 30 of the recess hit the hook profile 28 of the latching member 5, the latching member 5 moves in the opening direction P1, whereby the guide part 26 moves along the guide rail 8 into the second guide area 23. The latching member 5 can be pivoted around the guide mechanism 25, which rests on the guide rail 8 in the second guide area 23. When the latching member 5 is pivoted, the hook section 27 can be deflected upward in the direction of the ejector 6, wherein the hook section 27 hooks onto the end contour 32 of the ejector 6. Once the guide part 26 of the latching member 5 reaches the second guide area 23 of the guide rail 8, the force unit 4 can be unloaded. As a result, the latching member 5 is moved in the opening direction P1. Since the hook section 27 of the latching member 5 hooks onto the ejector 6, the ejector 6 also moves in the opening direction P1 until it reaches the second open position (see Figure 12 to Figure 14 ). The drawer 53 moves in the opening direction P1 by the stop member 31 of the ejector 6.

[0061] In the second open position, the force unit 4 is unloaded. Fig.14 As can be seen in the figure, the edge contour 30 of the recess 29 rests on the hook contour 28 of the latching member 5. In addition, the guide mechanism 25 and the guide part 26 are located in the second guide area 23 of the guide rail 8, wherein the guide mechanism 25 is horizontally spaced apart from the guide part 26. Compared with the guide part 26, the guide mechanism 25 is further forward in the opening direction P1.

[0062] In the first open position (see Fig. 9 ) to the second open position (see Fig.12 ), during the opening movement of the ejector 6, the elastic rod 15 first moves along the first straight region 33 of the guide slot 17 of the ejector 6. The elastic rod 15 is fixedly arranged according to the position on the heart-shaped curve portion 16. With further movement in the opening direction P1, the elastic rod 15 moves to the right or in the direction of the force unit 4 through the lateral region 34 of the guide slot 17 and then moves along the second straight region 35. The elastic rod 15 thus reaches the right section of the heart-shaped curve portion 16 (see Fig.12 ), and the synchronous plate 18 can be pulled back to the starting position by the spring 19.

[0063] During the closing movement of the ejector 6 in the closing direction P2, i.e., in particular when the drawer is pushed closed by the user and the drawer drives the ejector 6 in the closing direction P2, the spring rod 15 is first moved along the second straight region 35 of the guide slot 17, optionally with the aid of an automatic retraction mechanism providing a force-operated damping, until the spring rod 15 abuts against the transition between the second straight region 35 and the lateral region 34. When the spring rod 15 abuts against the transition, then during the further closing movement of the ejector 6, the spring rod 15 and thus also the displacement element 10 can be moved in the closing direction P2 by means of the force accumulator 7, wherein the force accumulator 7 is charged. In this case, the spring rod 15 is guided along the section 36 extending straightly to the right of the heart-shaped curve 16 until the end of this section 36, after which the spring rod 15 follows the heart-shaped curve 16 and moves to the left in the direction of the spring 19. The spring rod 15 thus also reaches the first straight region 33 of the guide slot 17. The elastic rod 15 is locked in the heart-shaped curve portion 16, so that in the further closing movement of the ejector 6, the elastic rod 15 moves along the first straight region 33. In the further closing movement of the ejector 6, the closed position is reached (see Figure 6 ).

[0064] When the ejector 6 is moved in the closing direction P2, the force unit 4 is directly loaded by the hook section 27 resting against the end contour 32 of the ejector 6. Here, the guide mechanism 25 and the guide part 26 can be moved along the second guide area 23 of the guide rail 8 until the guide part 26 reaches the first guide area 22 and pivots downward. As a result, the hook section 27 of the latching member 5 no longer rests against the end contour 32 of the ejector 6, so that the ejector 6 can move relative to the latching member 5 in the closing direction. Here, the connecting section 24 of the latching member 5 moves along the recess 29 of the ejector 6. If the synchronizing plate 18 is not pulled in the closing direction P2 by the tensioned spring 19, the stop on the moving part 10 contacts the mating stop on the synchronizing plate 18 when the force accumulator 7 is loaded. As a result, the synchronizing plate 18 returns to its starting position.

[0065] Fig.15 It is shown that there is a stop 37 which has a stop surface 38 on the sliding part 10 or the ejector and a stop surface 39 on the synchronization plate 18. Fig.15 The two stop surfaces 38 and 39 are separated or spaced apart from each other by a few millimeters in the moving direction of the moving element 10 or in the direction P1 or P2. This is because the synchronization plate 18 is retracted in the starting position due to the active tension spring force of the spring 19 and is ready for the synchronization process.

[0066] The stop element 37 has a protruding projection 10 a on the outer contour of the sliding part 10 that can be coupled to the ejector 6 .

[0067] The synchronous plate 18 can reciprocate along the directions P1 and P2. When a tension F1 (see FIG. 1 ) is applied to the synchronous plate 18 by a spring 19 such as a spiral spring along the direction P2, Fig.15 ) and moves to the Fig.15 starting position.

[0068] Fig.16 and 17 The entraining contact between the stop surfaces 38 and 39 is shown when the synchronization plate 18 is still in the adjustment position despite the spring 19, ie remains in the adjustment position or is blocked after the synchronization movement. Fig.16 , 17 This can occur, for example, due to friction effects if the force of the spring 19 is not sufficient to move the synchronizing plate 18 from the Fig.16 , 17 When the drawer 53 is closed and the ejector 6 is thereby moved and the moving part 10 is moved in the direction P2, the moving part 10 drives the synchronizing plate 18 together to the starting position. Here, the stop surface 38 is pressed against the stop surface 39 and pushes the synchronizing plate 18 in the direction P2. The synchronizing plate 18 is forced to return to the starting position with the help of the force F1.

[0069] After this, when the drawer is still closed, the synchronous plate 18 is in the starting position. Then, when the drawer is operated to be closed next time, the synchronous plate 18 can be driven by the force accumulator 7 that is loaded to unlock through the touch lock function.

[0070] Without the stop 37 , it cannot be reliably ruled out that the synchronizing plate 18 remains in the adjusted position and that no synchronization occurs during the next locking process.
