Furthermore, the invention relates to a method for disassembling such an assembly. Finally, the invention relates to a method for assembling such an assembly. Background Technology
[0002] A lock for retaining a first component to a second component is known from CN 107487232B. The lock includes a retaining body having a socket for receiving a protruding portion of the second component. The retaining body has a wall forming the boundary of the socket. The lock also has a locking element slidably disposed within the retaining body. The locking element has a protrusion, wherein the locking element has a first position in which the protrusion protrudes from the wall by a first amount into the socket (locked position), and the locking element has a second position in which the protrusion protrudes from the wall by a second amount into the socket, wherein the second amount is less than the first amount, or, in the second position, the protrusion does not protrude from the wall (released position). The protrusion is movable relative to the retaining body in a retraction direction from the first position to the second position.
[0003] A lock for retaining a first component to a second component is also known from US 8,780,797. A lock for retaining a first component to a second component is also known from CN104512280. A lock for retaining a first component and a second component is also known from KR 101403858 B1. Summary of the Invention
[0004] In view of this background, the problem to be solved by the present invention is to provide a lock for holding a first component to a second component, which can be more easily operated by a worker.
[0005] This problem is solved by the lock according to the invention, the components according to the invention, and the method according to the invention. Preferred embodiments are given in the description below.
[0006] The basic concept of the lock according to the invention is that the retraction direction is the rotational retraction direction, and in some sense the opposite of the pushing direction, in which the locking element can move. For example, in CN 107487232, pushing the locking element causes the protrusion to move in the same direction as the pushing direction. Here, the retraction direction is the same as the pushing direction. However, this means that space needs to be provided at the opposite end of the retaining body so that the protrusion can be at least partially moved out of the socket when the locking element is pushed. However, the basic concept of the invention is that the retraction direction of the protrusion is opposite to the direction of the pushing movement of the locking element.
[0007] This basic concept of the invention is achieved by providing a lock according to the invention having at least one rod. According to the invention, the rod has a first end and a second end arranged opposite to the first end, wherein a protrusion is attached to the first end of the rod or forms part of the first end of the rod. According to the invention, the rod is connected to a retainer via a swivel joint, or the rod is connected to an attachment via a swivel joint, wherein the attachment is attached to the retainer.
[0008] The rotating junction is located between the first and second ends of the rod.
[0009] According to the invention, applying a force toward the socket to the second end causes the rod to rotate within the rotating junction. This causes the protrusion to move in the retraction direction. In other words, providing the rod allows the force applied to the second end of the rod to be converted into movement of the protrusion in the opposite direction. Pushing the locking element causes the protrusion to be pulled out.
[0010] The lock has a retainer with a socket for receiving a protruding part of a second component. The retainer can be a separate body capable of being attached to the first component. The retainer can be made, for example, by injection molding. However, the retainer can also be made as part of the first component.
[0011] The retainer has walls that form the socket boundary. The retainer may have more than one wall forming the socket boundary. For example, if the socket has a rectangular cross-section, the retainer will have a first wall, a second wall, a third wall, and a fourth wall, all forming the socket boundary and giving the socket a rectangular shape between them. In a preferred embodiment, the socket has a bottom wall. The socket is preferably cul-de-sac shaped, having an opening that allows a protruding part of a second component to be inserted into the remainder of the socket defined by the walls. The bottom wall can serve as a constraint on pushing the protruding part of the second component into the socket. The protruding part of the second component may only be pushed into the socket before its tip contacts the bottom wall of the socket. However, a design where the socket has no bottom wall is also feasible. A design where the walls of the retainer forming the socket boundary have openings is also feasible. The walls forming the socket boundary can also be more like a frame.
[0012] The retainer described in this invention has a wall forming the boundary of the socket so as to define a reference plane within the retainer relative to which the position of the protrusion of the locking element, which can describe the locked position and the released position, can be described.
[0013] In a preferred embodiment, a wall forming the socket boundary is arranged on a first member of the retainer, wherein another wall is further provided on the other side of the socket and facing this wall, wherein this additional wall is arranged on a second member of the retainer. In a preferred embodiment, the first member of the retainer has an upper surface arranged in a first plane, wherein the second member of the retainer has an upper surface arranged in a second plane, wherein the first plane is above the second plane. In a preferred embodiment, the first member of the retainer is longer than the second member of the retainer.
[0014] In a preferred embodiment, the retainer has an outward-facing surface that is flush with the outward-facing surface of the rod. In another preferred embodiment, a first component of the retainer has an outward-facing surface that is flush with the outward-facing surface of the rod. This flush alignment of the retainer's outward-facing surface with the rod prevents the rod from being pushed by a large object. The flush alignment of the retainer's outward-facing surface with the rod requires the rod to be pushed by an element having the same size as or smaller than the rod's outward-facing surface. In a preferred embodiment, when the rod is in the first position, no portion of the second end of the rod protrudes beyond the outward-facing surface of the retainer.
[0015] In a preferred embodiment, the wall forming the socket boundary may have a hole or a recess, and the locking element may protrude into the socket through the hole or recess. According to the invention, the locking element has a second position, wherein in the second position, the protrusion is in a released position, wherein in the released position... A second protrusion, smaller than the first, extends from the wall into the socket. Or the protrusion does not protrude from the wall.
[0016] In a preferred embodiment, where the wall forming the socket boundary has a hole or recess, the locking element in the second position is at least partially, preferably completely, disposed within the hole or recess. Therefore, in a preferred embodiment, when the locking element moves from the first position (locked position) to the second position (released position), the locking element moves deeper into the hole or recess. This includes the option that the locking element protrudes at least partially from the wall forming the socket boundary on the opposite side compared to the socket. This wall may have a first surface forming the socket boundary and a second surface disposed on the opposite side of the wall and thus away from the socket. The locking element may protrude from this second surface in the second position. This depends on the size of the locking element and the wall thickness. If the locking element is thicker than the wall thickness, the locking element will partially protrude from the second surface of the wall (the surface away from the wall) in the second position.
[0017] An embodiment in which the locking element is not disposed within the hole or recess in the first position is feasible. In such an embodiment, the locking element not disposed within the hole or recess in the first position will move into the hole or recess as it moves from the first position to the second position. This includes the option that the locking element protrudes at least partially from the wall forming the socket boundary on the opposite side (the second surface of the wall) compared to the socket. An embodiment in which the locking element is partially disposed within the hole or recess in the first position, but the locking element moves deeper into the hole or recess as it moves from the first position to the second position, is also feasible. This includes the option that the locking element protrudes at least partially from the wall forming the socket boundary on the opposite side (the second surface of the wall) compared to the socket.
[0018] In a preferred embodiment, the retainer has a first wall forming a socket boundary, wherein in the locked position, a protrusion extends from the first wall into the socket by a first amount, and wherein in the released position... A second protrusion, smaller than the first, extends from the wall into the socket. Or the protrusion does not protrude from the first wall. In this preferred embodiment, the retainer has a second wall forming the boundary of the socket, wherein the second wall is arranged opposite to the first wall, and wherein the second wall has a hole or recess, wherein the protrusion has a tip, and wherein the protrusion can be positioned such that the tip of the protrusion engages with the hole or recess in the second wall. In a first alternative, when the protrusion is in a locked position, the tip of the protrusion engages with the hole or recess in the second wall. In a second alternative, the tip of the protrusion engages with the hole or recess in the second wall in a forward position, wherein in the forward position, the protrusion protrudes from the first wall into the socket by an amount greater than a first amount.
[0019] In a preferred embodiment, the recess is provided in such a way that a section of the second wall protrudes toward the first wall relative to the other sections of the second wall.
[0020] The lock according to the invention has a locking element. The purpose of the locking element is to retain the protruding part of the second component in the socket once the protruding part of the second component has been inserted into the socket. For this purpose, the locking element has a protrusion. The locking element has a first position, wherein in the first position, the protrusion protrudes from the wall into the socket by a first amount. This position of the protrusion is called the locked position. The locking element also has a second position, wherein when the locking element is in the second position, the protrusion protrudes from the wall into the socket by a second amount, wherein the second amount is less than the first amount, or alternatively, when the locking element is in the second position, the protrusion does not protrude from the wall into the socket at all. When the locking element is in the second position, the position of the protrusion is called the released position.
[0021] The form and shape of the protrusion can be selected based on the form and shape of the protruding part of the second component received in the socket. According to the invention, it is desirable for the protrusion in the locked position to prevent the protruding part of the second component from retracting from the socket, while the protrusion in the released position allows the protruding part of the second component to retract from the socket.
[0022] According to the invention, the protrusion can move relative to the retainer from the locked position to the released position in the rotational retraction direction, for example, in the circumferential direction of the rotational movement.
[0023] In a preferred embodiment, the rod is a longitudinal element. A longitudinal element is understood to have a length, a height, and a width, wherein the maximum length is at least twice, preferably at least three times, and more preferably at least four times greater than the maximum width and / or maximum height of the element. In a preferred embodiment, the rod is a solid element that functions similarly to a bar.
[0024] According to the invention, the rod has a first end and a second end arranged opposite to the first end, wherein a protrusion is attached to the first end of the rod. The protrusion can be attached directly and rigidly to the first end of the rod; it can even be integrally formed with the rod. This would mean that the protrusion will follow the movement path of the first end during its movement.
[0025] In one alternative embodiment of the invention, the rod is connected to the retainer via a swivel junction, wherein the swivel junction is disposed between a first end and a second end. In a second alternative embodiment of the invention, the rod is connected to an attachment via a swivel junction, wherein the attachment is attached to the retainer.
[0026] The rod, junction, and attachment can all be part of a one-piece component, such as a molded component. In a preferred embodiment, the junction is provided by a torsion bar. The rod, torsion bar, and attachment can all be part of a one-piece component, such as a molded component.
[0027] According to the invention, applying a force toward the socket to the second end of the rod causes rotational movement of the rod in the rotating junction, resulting in movement of the protrusion in the rotational retraction direction. By introducing the rod, the invention provides the possibility that a force applied in one direction (e.g., a thrust applied to the locking element) can be converted into movement of the protrusion of the locking element in the opposite direction by the rotation of the rod in the rotating junction.
[0028] In a preferred embodiment, the attachment has a first end attached to the junction and a second end located away from the first end. In a preferred embodiment, a locking protrusion is arranged at the second end of the attachment protrusion, wherein the locking protrusion can engage with a portion of the retainer to retain the attachment in a predetermined position within the retainer.
[0029] In a preferred embodiment, a guide arm is disposed at the second end of the attachment, wherein the guide arm is disposed in a channel in the retainer.
[0030] In a preferred embodiment, the retainer is made of a plastic material. In a preferred embodiment, the retainer is formed by injection molding. In a preferred embodiment, the locking element is made of a plastic material. In a preferred embodiment, the locking element is formed by injection molding. For example, the locking element can also be formed by stamping from a blank.
[0031] In a preferred embodiment, the retainer and / or locking element, and most preferably the entire lock, is designed to be mirror-symmetric about the plane of the split protrusion and including the retraction direction.
[0032] In a preferred embodiment, the protruding part of the second component is introduced into the socket along the linear insertion direction.
[0033] In a preferred embodiment, the axis of rotation around which the rod rotates in the rotating junction is not parallel to the linear insertion direction, and is preferably perpendicular to the linear insertion direction.
[0034] In a preferred embodiment, the retainer and / or locking element, and most preferably the entire lock, is designed to be mirror-symmetric about a plane including the retraction direction and the linear insertion direction.
[0035] In a preferred embodiment, the protrusion of the locking element is designed in a wedge shape. In a preferred embodiment, the protrusion of the locking element has a pointed tip. In a preferred embodiment, the wedge-shaped protrusion of the locking element has its thinnest portion at the tip, and then increases in thickness as it moves away from the tip. The wedge-shaped protrusion may have a push-back surface on its underside, which may contact the protrusion when the protruding member moves upward and if the protrusion is in or near the release position. For example, if the protrusion has moved from the locked position to the release position and has reached or is near the release position, and is in the path of the protrusion, then when the protrusion contacts the push-back surface of the wedge-shaped protrusion, the push-back surface of the protrusion may cause the protrusion to push the protrusion further in the release direction.
[0036] In a preferred embodiment, the protrusion may have a pull-out surface on its underside, the pull-out surface pointing towards the wall and arranged at an angle to the release direction, wherein the pull-out surface may contact the protrusion when the protrusion moves upward and if the protrusion is in or near the locked position. For example, if the protrusion is in or near the locked position and is in the path of the protrusion, then when the protrusion contacts the pull-out surface, the pull-out surface may cause the protrusion to pull the protrusion further away from the wall and against the release direction. This arrangement can be used, for example, to contact the tip of the protrusion with a hole or recess in the second wall of the socket. This arrangement can secure the protrusion in the socket. The more attempts are made to pull the protrusion out of the socket, the more the protrusion is pulled out, and prevents the protrusion from being pulled out of the socket.
[0037] In a preferred embodiment, the locking element has a spring. The spring may be a torsion bar in the junction. Alternatively or supplemented, a spring, such as a leaf spring or a coil spring, may be provided. In a preferred embodiment, the spring is tensioned when the rod moves to bring the locking element from a first position to a second position. If the spring is tensioned when the rod moves to bring the locking element from the first position to the second position, once the force is removed, the spring will push the rod and thus push the locking element back toward the first position.
[0038] In a preferred embodiment, when the locking element is in the second position, the spring is loaded. The loading of the spring preloads the locking element to move from the second position to the first position.
[0039] In a preferred embodiment, the lever is part of the locking element. In a preferred embodiment, the protrusion, the lever, and—if present—the locking protrusion of the lever and the guide arm of the lever are all part of the locking element and are integrally formed, for example by injection molding or by stamping from a blank.
[0040] In a preferred embodiment, the rotating junction defines a rotation axis, and the rod rotates about the rotation axis, wherein the rotation axis is not parallel to the insertion direction, which is the direction along which the protruding part of the second component intends to be inserted into the socket. In a preferred embodiment, the insertion direction is parallel to the direction extending from the surface of the wall forming the socket boundary.
[0041] In a preferred embodiment, a torsion bar is configured to extend from the rod, having an end that is held in a retainer or attachment. The torsion bar can serve as a spring to preload the protrusion into a locked position. If the rod rotates, causing the protrusion to move from the locked position toward the released position, the torsion bar is loaded. If the force applied to the rod that causes the rod to rotate and move the protrusion from the locked position toward the released position is reduced or canceled, the loaded torsion bar causes a return movement of the rod and causes the protrusion to move toward the locked position, preferably into the locked position.
[0042] In a preferred embodiment, the retainer has a recess, and the attachment has a portion disposed within the recess. In a preferred embodiment, the circumferential wall of the recess forming the retainer and the circumferential wall of the portion of the attachment disposed within the recess are adapted to each other to prevent rotation of the attachment. In a preferred embodiment, the recess is polygonal, preferably square, triangular, or rectangular. In a preferred embodiment, the portion of the attachment disposed within the recess is polygonal, preferably square, triangular, or rectangular.
[0043] In a preferred embodiment, the recess has a bottom wall and a channel extending further from the bottom wall into the retainer. In a preferred embodiment, the attachment has a portion disposed in the recess and having an abutting surface against the bottom wall, wherein the attachment has an arm extending into the channel. In a preferred embodiment, the arm has a locking protrusion. In a preferred embodiment, the locking protrusion engages with a portion of the retainer opposite to the bottom wall, such that engagement of the locking protrusion with this portion prevents the attachment from being pulled out of the recess.
[0044] In a preferred embodiment, the retainer has an attachment protrusion that can be used to attach the retainer to the first component.
[0045] In a preferred embodiment of the component according to the invention, the first component has a recess, and the retainer is at least partially disposed within the recess. An attachment protrusion may be used to define the position of the retainer within the recess of the first component, for example, determining how deep the retainer can be inserted into the recess. The attachment protrusion may project laterally from the retainer and may form surface contact with a lateral surface of the first component surrounding the recess of the first component, thereby defining the position of the retainer within the recess of the first component. The retainer may be glued or welded to the first component. In a preferred embodiment, the retainer is attached to the first component by gluing or welding the attachment protrusion to the first component. Furthermore, as an alternative or supplement, the retainer may be wedged or pressed into the recess of the first component. Ribs may be provided on the outward-facing surface of the retainer, particularly on the wall or the attachment protrusion, which facilitates wedging into the recess of the first component.
[0046] The component according to the invention has a first part and a second part, wherein the first part is connected to a retainer of the lock (to be understood to include those embodiments in which the retainer is an element of the first part), wherein the second part includes a protruding part having an opening or a recess, the protruding part being arranged in a socket, and wherein a protrusion of a locking element is in a locked position and is at least partially arranged inside the protruding part.
[0047] In a preferred embodiment, the protruding member is a U-shaped protruding member. In a preferred embodiment, the protruding member may be part of a hook. In a preferred embodiment, the protruding member may have a wedge-shaped portion at its end, which forms the tip of the protruding member and wherein the protruding member has a recess at the end of the wedge-shaped portion, which is preferably designed as a step following the wedge-shaped portion.
[0048] In a preferred embodiment, the protruding part is a metal wire. In an alternative embodiment, the protruding part is a part stamped from a metal sheet.
[0049] In a preferred embodiment, the first component is part of the vehicle, such as a rear seat cushion. In a preferred embodiment, the second component of the assembly is part of the vehicle, such as the vehicle frame, floor, or wall. In a preferred embodiment, the lock according to the invention is used to attach a portion of the cushion, particularly a rear seat cushion, to the vehicle body.
[0050] The method for disassembling an assembly according to the invention is characterized in that a force applied to the second end of the rod is directed in the opposite direction to the retraction direction. This force causes the rod to rotate around a protrusion of the retainer or in the rotating junction, and causes the protrusion to move in the retraction direction to a release position, wherein in the release position, the protrusion of the locking element is arranged outside the U-shaped protrusion. As part of the method according to the invention, the U-shaped protrusion is removed from the socket.
[0051] The method for assembling components according to the present invention provides: In the first step, the protruding part of the second component is arranged inside the lock's socket, and the protrusion of the locking element is in a first position and is at least partially arranged inside the protruding part. In the second step, the first component is connected to the lock's retainer.
[0052] This provides an opportunity whereby the protrusion of the second component can be delivered pre-assembled, with the lock attached to the protrusion of the second component by means of a protrusion for attaching the locking element, which is in a first position and at least partially arranged inside the protrusion. Attachment to the first component is then performed by attaching the lock's retainer to the first component. While in the prior art, the lock is typically attached to the first component before the assembly is completed, this assembly method first assembles the lock to the second component and then attaches the lock's retainer to the first component.

Detailed Implementation
[0054] Figure 1 A lock 1 is shown for holding a first component to a second component. The lock 1 includes a retaining body 2 and a locking element 3. The retaining body 2 has a socket 4 for receiving a U-shaped protrusion 5 of the second component. The retaining body has a wall 6 forming the boundary of the socket, as well as additional walls 7 and a bottom wall 10. The socket is a cul-de-sac.
[0055] The locking element 3 has a protrusion 11. The locking element 3 has Figure 1 , 4 The first position is shown in Figures 6 and 7. In the first position of the locking element 3, the protrusion 11 protrudes from the wall 6 into the socket 4 by a first amount. This position of the protrusion 11 is called the locked position.
[0056] Locking element 3 has a second position (such as...) Figure 5 and 8 (As shown). In the second position, the protrusion 11 protrudes a second amount from the wall 6 into the socket 4, where the second amount is smaller than the first amount. This position of the protrusion 11 is referred to as the release position.
[0057] In the locked position, the protrusion 11 is positioned inside the U-shaped protrusion 5 and prevents the protrusion 5 from being retracted (pulled out) from the socket 4 (see...). Figure 6 , 7In the release position, protrusion 11 is positioned outside the U-shaped protrusion 5 and allows the protrusion 5 to be retracted (pulled out) from the socket 4 (see...). Figure 8 ).
[0058] The protrusion 11 can move from the locked position to the released position relative to the retainer 2 in the rotational retraction direction A.
[0059] The lock 1 has a lever 12. The lever 12 has a first end 14 and a second end 15 arranged opposite to the first end 14. A protrusion 11 forms part of the first end 14 of the lever 12.
[0060] like Figure 3 , 7 As shown, rod 12 has two torsion bars 17, which serve as part of the junction. The corresponding torsion bars 17 are arranged between rod 12 and attachment 23. The protrusions of attachment 23 are supported in corresponding recesses 18 within retainer 2.
[0061] The retainer 2 has a recess 24 (see Figure 2 The attachment has a portion 25 disposed in the recess 24. The recess is square, and the portion 25 of the attachment 23 disposed in the recess 24 is square.
[0062] The recess 24 has a bottom wall 26 and a channel 27 extending further from the bottom wall 26 into the retainer 2. In a preferred embodiment, the attachment 23 has a portion 25 disposed in the recess 24 and having an abutting surface 28 abutting against the bottom wall 26, wherein the attachment 23 has an arm 20 extending into the channel 27. The arm 20 has a locking protrusion 21. The locking protrusion 21 engages a portion of the retainer 2 facing away from the bottom wall 26 such that engagement of the locking protrusion 21 with this portion prevents the attachment 23 from being pulled out of the recess 24.
[0063] Figure 5 and 8 Lock 1 without attachment 23 and torsion bar 17 is shown to better understand the movement of lever 3.
[0064] from Figure 6 As can be best seen from the image, the wall 6 forming the boundary of the socket 4 is arranged on the first part of the retainer 2. Figure 6 On the left side of the socket 4, another wall 7 is provided on the other side of the socket 4 and facing the wall, wherein the other wall 7 is arranged on the second part of the retainer 2. Figure 6 (Right-hand side of the image). The first component of the retainer 2 has an upper surface arranged in a first plane, and the second component of the retainer 2 has an upper surface arranged in a second plane, wherein the first plane is above the second plane. The first component of the retainer 2 is longer than the second component of the retainer 2.
[0065] from Figure 4 and Figure 5 As can be best seen, the retainer 2 has an outer surface 43 that is flush with the outer surface 44 at the second end 15 of the rod 3. The first component of the retainer 2 has an outer surface 43 that is flush with the outer surface 44 at the second end 15 of the rod 3. This flush arrangement of the outer surface 43 of the retainer 2 with the outer surface 44 of the rod 3 prevents the rod 3 from being pushed by a large object. The flush arrangement of the outer surface 43 of the retainer 2 with the outer surface 44 of the rod 3 requires that the rod 3 be pushed by a component with the same size as or smaller than the outer surface of the rod 3. For example, from... Figure 1 , 4 As can be seen from Figures 6 and 7, when rod 3 is in the first position, no part of the second end 15 of rod 3 protrudes beyond the outward-facing surface of the retainer 2.
[0066] from Figure 6 , 7 Starting from the first position of the locking element shown, applying a force toward the second end 15 of the lever 12 towards the socket 4 causes the lever 12 to rotate about the axis of the torsion bar 17 and the protrusion 11 to move in the retraction direction A. In doing so, the protrusion 11 can move from the locked position (…). Figure 6 , 7 ) to release position ( Figure 8 )move.
[0067] Torsion bar 17 acts as a spring. In the first position of locking element 3 ( Figure 6 , 7 As the locking element 3 moves from the first position to the second position, the torsion bar 17 is torn and thus subjected to load.
[0068] In the disassembly method, starting from the first position of locking element 3, as follows: Figure 6 , 7 As shown A force directed toward the socket 4 is applied to the second end 15, which causes the rod 12 to rotate about the axis of the torsion bar 17 and thus about the rotational junction, and the protrusion 11 to enter the second position in the rotational retraction direction A. Figure 8 The movement of ), wherein in the second position, the protrusion 11 is in the release position, wherein in the release position: The protrusion 11 either protrudes a second amount from the wall 6 into the socket, where the second amount is smaller than the first amount. Either protrusion 11 does not protrude from wall 6, as well as Remove the U-shaped protruding part 5 from the socket 4.
[0069] Figure 5The retainer 2 is shown to have a first wall 6 forming the boundary of the socket 4, wherein in the locked position, a protrusion 11 protrudes from the first wall 6 into the socket 4 by a first amount, and wherein in the released position: The protrusion 11 protrudes from the first wall 6 into the socket 4 by a second amount, wherein the second amount is smaller than the first amount.
[0070] The retainer 2 has a second wall 7 forming the boundary of the socket 4, wherein the second wall 7 is arranged opposite to the first wall 6, and wherein the second wall 7 has a recess 30. The protrusion 11 has a tip 31, wherein the protrusion 11 can be positioned to engage with the recess 30 in the second wall 7 (e.g., Figure 6 (As shown). The tip 31 of the protrusion 11 preferably engages with the recess 30 in the second wall 7 when the protrusion 11 is in the locked position. The recess 30 is provided in such a way that a section 32 of the second wall 7 protrudes toward the first wall 6 relative to the other sections 33 of the second wall 7.
[0071] Figure 6 The wedge-shaped protrusion 11 is shown to have a push-back surface 34 on its underside, which can contact the protrusion 5 when the protrusion 5 moves upward and if the protrusion 11 is in or near the release position. For example, if the protrusion 11 has already moved from the locked position (e.g., Figure 5 If the protruding member 5 moves toward the release position and has reached or is close to the release position, and is in the path of the protruding member 5, then when the protruding member 5 contacts the push surface 34 of the wedge protrusion 11, the push surface 34 of the protrusion 11 can cause the protruding member 5 to push the protrusion 11 further toward the release direction A.
[0072] Figure 6 The wedge-shaped protrusion 11 is shown to have a pull-out surface 35 on its underside, which points toward the wall 6 and is arranged at an angle to the release direction, wherein when the protruding member 5 moves upward and if the protrusion 11 is in or near the locked position ( Figure 6 When the protrusion 11 is in or near the locked position, the pull-out surface 35 can contact the protruding part 5. For example, if the protrusion 11 is in or near the locked position... Figure 6 And since the protruding part 5 is in the path of the protruding part 5 at that position, when the protruding part 5 contacts the pull-out surface 35, the pull-out surface 35 can cause the protruding part 5 to pull the protrusion 11 further away from the wall 6 in the opposite direction of the release direction.
[0073] Figure 9 and 10 Another embodiment of lock 1 is shown, in which the same reference numerals are used for the same parts. Figure 9 and Figure 10 The embodiments show that the torsion bar 17 and Figure 3 Compared to its modified shape (compared to) Figure 3 The design of the torsion bar is more rounded, and the attachment 23 has been slightly redesigned.
[0074] Figure 1 , 2 Figures 4, 5, 6, and 8 show that the wall 6 forming the boundary of the socket 4 has a hole 40. (As shown...) Figure 6 As shown in the best embodiment, the locking element 3 protrudes into the socket 4 through the hole 40. The locking element 3 has a second position (e.g., Figure 5 and 8 (As shown). In the second position, the protrusion 11 protrudes a second amount from the wall 6 into the socket 4, wherein the second amount is smaller than the first amount. Figure 6 As shown, the locking element is partially disposed in the hole 40 in the second position. When the locking element 3 is in the first position (locked position; for example)... Figure 6 Move to the second position (release position, e.g.) Figure 8 When this occurs, the locking element moves deeper into hole 40. For example... Figure 5 and Figure 8 As best shown, the locking element protrudes at least partially from the wall 40 forming the boundary of the socket 4 on the opposite side compared to the socket 4. The wall 6 may have a first surface 41 forming the boundary of the socket 4 and a second surface 42 disposed on the opposite side of the wall 6 and thus away from the socket. The locking element 3 protrudes from this second surface 42 in a second position (see...). Figure 5 and 8 The locking element 3 is partially disposed within the hole 40 in the first position (see...). Figure 6 However, as the locking element 3 moves from the first position to the second position (see...), Figure 5 and 8 As it moves, locking element 3 moves deeper into hole 40.
[0075] like Figure 1 As shown in the best embodiment, the retainer 2 has features that allow it to be attached to the first component ( Figure 1 Attachment protrusions 45, 46, and 47 (not shown in the image). Figure 11 A cross-sectional view of the component according to the invention is shown. A retainer 2 is disposed in a recess 50 of a first member 51. An attachment protrusion 46 defines the position of the retainer 2 within the recess 50 of the first member 51, i.e., determines the depth to which the retainer 2 is inserted into the first member 51. The attachment protrusion 46 protrudes laterally from the retainer 2 and makes surface contact with the lateral surface of the first member 51 surrounding the recess 50 of the first member 51, thereby defining the position of the retainer 2 within the recess 50 of the first member 51. The retainer is attached to the first member 51 by gluing the attachment protrusion 46 to the first member 51. Furthermore, the retainer is wedged into the recess 50 of the first member 51. Ribs 52 are provided on the outward-facing surface of the retainer, which facilitates wedging into the recess of the first member.
