Description

[Technical field]

[0001] The present invention relates to a lock-linked animal stand that is attached to a lock installed in a private room such as a public toilet. [Background technology]

[0002] Storage racks have been proposed to prevent small items from being left behind in private rooms such as public restrooms. Patent Document 1 discloses a hook for hanging small items that appears by converting the translational motion of a slide latch into rotational motion. Patent Document 2 discloses a storage rack installed on a lock such as a slide latch or a strike lock. Patent Document 3 discloses a storage rack that can be attached to an already installed strike lock. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Application No. 58-062314 [Patent Document 2] Patent Publication No. 2006-028900 [Patent Document 3] Patent Publication No. 2019-031847 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Documents 1 and 2, because the slide latch and the storage table are integrated into one structure, it is not possible to attach a storage table to a private room where a slide latch is already installed. In Patent Document 3, a storage table can be attached to a rotating strike lock by additional work, but a rotating storage table cannot be attached to a widespread slide latch. Next, a problem with attaching a storage table by additional work is that a malfunction may occur in the interlocking between the existing lock and the storage table, causing a "lock failure" in which the private room cannot be locked or unlocked. Another problem is the phenomenon of "locking out" in which the lock unintentionally locks due to impact when the door is closed without being fully unlocked when leaving the private room. This phenomenon occurs less frequently with a slide latch type door, but adding a rotating storage table may increase its frequency. Therefore, an object of the present invention is to provide a storage rack that can be attached in addition to an already installed slide latch, and to prevent lock failure and lockout. [Means for solving the problem]

[0005] The lock-linked storage stand, which can be installed in addition to an already installed slide latch, has a conversion part that converts the rotation of the rotatable storage stand into translational motion, and the translational motion converted by the conversion part is transmitted to the latch to operate the latch.

[0006] To prevent lock failure, the lock-linked object stand is provided with a control means that enables the sliding latch to be locked and unlocked by either the rotational operation of the object stand or the translational operation of the latch.

[0007] In order to prevent lockout, the lock-linked storage stand is provided with a rotatable storage stand, a lock for locking the door by rotating the storage stand, and a restricting means for restricting the locking operation caused by the rotation torque of the storage stand due to its own weight. Effect of the Invention

[0008] By providing a conversion section that converts rotational motion into translational motion as a unit, the lock-linked device stand can be installed by performing a simple additional operation on an existing slide latch.

[0009] The lock-linked storage stand is provided with a portion where the latch can be directly and manually operated, and further, a structure is provided for cutting off the link between the rotational movement of the storage stand and the translational movement of the latch, thereby making it possible to manually operate the latch and preventing lock-out.

[0010] Lockout can be prevented by making the thrust force required to translate the latch greater than the torque of its own weight that rotates the inverted storage platform to a horizontally stable position. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a lock-linked animal stand according to the present invention will be described in detail with reference to the accompanying drawings. EXAMPLES

[0013] FIG. 1 is a schematic perspective view of a lock-linked animal stand A according to the present invention attached to a door C, and the lock-linked animal stand A is attached to a slide latch B that has already been attached to the door C by additional work. In FIG. 1, the latch 51 of the slide latch B (hidden by the lock-linked animal stand A in FIG. 1 and not visible) is attached to the door C, and the corresponding strike 52 is attached to the support D, which is a wall, but the latch 51 may be attached to the support D and the strike 52 may be attached to the door C. In FIG. 1, the door C is in a locked state, and when the storage table U10 constituting the storage table U10 is rotated in the direction of the arrow 10a from this state, the latch 51 retreats from the strike 52, and the door C is unlocked. In this way, the rotational motion of the storage table U10 is converted into the translational motion of the latch 51, and the door C is locked and unlocked.

[0014] FIG. 2 is an explanatory diagram of the lock-linked animal stand A according to the present invention, in which FIG. 2(a) is a perspective view of the slide latch B, FIG. 2(b) is a perspective view of the lock-linked animal stand A attached to the latch 51 from above, and FIG. 2(c) is a perspective view of the lock-linked animal stand A attached to the latch 51 from below. In FIG. 2(a), the slide latch B attached to the door C is composed of a latch base 50, a latch 51, and a strike 52, and the latch 51 is provided so as to be capable of translational movement in the direction of an arrow 51a relative to the latch base 50. The strike 52 is provided on the support D, and the door C is locked (locked) to the support D by inserting the latch 51 into the strike 52. (Hereinafter, the door C is locked, or the door C is in a locked state.) Also, the door C is unlocked (unlocked) from the support D by retracting the latch 51 from the strike 52. (Hereafter, door C is unlocked, or door C is in an unlocked state.) In FIG. 2(b), the lock-linked animal storage stand A has the tray 10 upside down, with the back cover 11 facing up. Therefore, it cannot be used as a storage stand. If the storage stand U10 is now rotated around the rotation axis 21a in the direction of the arrow 10b, the tray 10 will face up and it will be usable as a storage stand. At this time, the latch 51 is inserted into the strike 52, and door C will be in a locked state. (FIG. 2(c))

[0015] FIG. 3 is an exploded perspective view of the lock-linked animal stand A according to the present invention, and shows the tray 10 in an upside-down state, similar to FIG. 2(b). Here, the tray 10 on which the article is placed and the back cover 11 are screwed together by the mounting hole 11a, the mounting screw hole 10g, and the screw 11b. The reinforcing plate 14 is screwed together with the tray 10 by the mounting hole 14a and the mounting screw hole 10h. The screw part 21b of the shaft 21 is screwed into the shaft hole 20c provided in the table seat 20b of the frame 20 constituting the rotation support part U20. The shaft 21 is passed through the shaft hole 12a of the table 12, and the table 12 is supported so as to be rotatable around the axis of the shaft 21. The shaft 21 is sandwiched between the tray 10 and the back cover 11, and the retaining frame 10e provided on the tray 10 and the retaining frame (not shown) provided on the back cover 11 enter the retaining groove 21c. This restricts the movement of the shaft 21 in the thrust direction. The cam pin 13 is inserted into the cam pin hole 12c provided in the table 12. A retaining frame 10f provided on the tray 10 and a retaining frame (not shown) provided on the back cover 11 fit into the retaining groove 13a provided in the cam pin 13. This restricts the movement of the cam pin 13 in the thrust direction. The table 12 rotates around the rotation axis 21a together with the tray 10 and the back cover 11. The tray 10, the back cover 11, and the table 12 form a storage stand U10.

[0016] The frame 20 has an arc hole 20a formed around the rotation shaft 21a of the storage table U10, and a cam pin 13 is inserted into the arc hole 20a. The cam pin 13 rotates around the center of the rotation shaft 21a along the arc hole 20a. The frame 20, which is a housing that covers the latch 51, has a notch 20g that allows the latch 51 to be directly contacted. The latch 51 can also be translated by inserting a finger into the notch 20g and pressing the latch 51. A screw 23b with a guide bush 24 is inserted into the sliding guide 30e of the conversion panel 30 that constitutes the conversion unit U30, and the conversion panel 30 is attached to the frame 20 by the screw 23b with the pressing plate 23 sandwiched therebetween. The pressing plate 23 is screwed into the frame 20 by the screw 23c. (See also FIG. 2(c)) Stoppers 20d that restrict the rotation of the storage table U10 are provided at both ends of the frame 20. The top cover 22 is provided with a mounting hole 22a for screwing onto the door C, and a flange 22b that covers the frame 20. The conversion panel 30 is provided with a cam groove 30a, into which the cam pin 13 is inserted. Therefore, when the cam pin 13 rotates around the rotation axis 21a, the rotational motion is converted into translational motion in the direction of the arrow 51a by the cam locus of the cam groove 30a. The details of the action of converting the rotational motion into translational motion by the cam groove 30a and the cam pin 13 will be described with reference to FIG. 4.

[0017] The bracket 40 constituting the transmission unit U40 is attached to the latch 51 with double-sided tape or the like, and the bracket 40 and the conversion panel 30 are engaged with the mounting screw hole 40a by matching the mounting hole 30b with the screw 40b. As a result, the translational motion of the conversion panel 30 in the direction of the arrow 51a is transmitted to the latch 51 via the bracket 40.

[0018] Although the double-sided tape joining of the bracket 40 and the latch 51 is excellent in terms of space saving and ease of installation, a possible problem is peeling off of the adhesive. If peeling occurs, the latch 51 will not operate even if the storage table U10 is rotated, and the door C cannot be locked or unlocked. As a measure to deal with such interlocking failure, the present invention provides a control means for translating the latch 51 independently of the rotation of the storage table U10. The control means is the aforementioned cutout portion 20g, and when a force is applied from the cutout portion 20g to the latch 51 in the direction of the arrow 51b in the unlocked state of the door C in FIG. 2(b), the latch 51 moves in that direction and the door C is locked. Also, when a force is applied to the tip of the latch 51 in the direction of the arrow 51c in the locked state of the door C in FIG. 2(c), the latch 51 moves in that direction and the door C is unlocked. In this way, by providing the cutout portion 20g in the frame 20, a safety measure against interlocking failure can be implemented.

[0019] FIG. 4 is an explanatory diagram of the operation of the lock-linked animal stand A according to the present invention, and FIG. 4(a), (b), and (c) are plan views showing the operation of the lock-linked animal stand A. FIG. 4(a) illustrates a state in which the latch 51 is inserted into the strike 52 and the door C is locked. When the storage stand U10 is rotated from this state in the direction of the arrow 10a in the first rotation range (approximately 90 degrees) 10c, FIG. 4(b) is obtained. In the state of FIG. 4(b), the latch 51 is retracted from the strike 52 and the door C is in an unlocked state. When the storage stand U10 is further rotated in the direction of the arrow 10a in the second rotation range (90 degrees) 10d, FIG. 4(c) is obtained. In FIG. 4(c), the door C is in an unlocked state as in FIG. 4(b), but the storage stand U10 has moved from the unstable inverted state of FIG. 4(b) to a stable state.

[0020] 4(d), (e), and (f) are plan views of the conversion panel 30 for explaining the cam locus, which correspond to the state of the lock-linked animal storage stand A in FIG. 4(a), (b), and (c), respectively. Here, the cam locus of the cam groove 30a is set so that the total rotation range of 180 degrees of the storage stand U10 is approximately halved and the translation amount of the latch 51 in the second rotation range 10d is smaller than that in the first rotation range 10c when the storage stand U10 is divided into the first and second rotation ranges 10c and 10d. Here, if the ratio of the translation amount of the latch 51 to the rotation amount of the storage stand U10 is defined as the translation ratio, the translation ratio in the second rotation range 10d is set smaller than the translation ratio of the latch 51 in the first rotation range 10c. Specifically, in the first rotation range 10c during the transition from the state of Fig. 4(d) to the state of Fig. 4(e), the conversion panel 30 moves by L1, but in the second rotation range 10d during the transition from the state of Fig. 4(e) to the state of Fig. 4(f), the conversion panel 30 does not move. Then, the latch 51 retreats from the strike 52 by the first rotation range 10c, and the door C is unlocked.

[0021] These movement amounts are set by the trajectory of the cam groove 30a and the rotation diameter of the cam pin 13 (the length from the center of the rotation shaft 21a to the cam pin 13) centered on the rotation shaft 21a, and the setting of the movement amount in the first rotation range 10c will be described first. In the state of FIG. 4(d) in which the door C is locked, the position of the cam pin 13 in the cam groove 30a is the first contact point 30C. In the state of FIG. 4(e) in which the door C is unlocked, the position of the cam pin 13 in the cam groove 30a is the second contact point 30d. At this time, if the length of the translational motion direction 51a of the line segment connecting the first contact point 30c and the second contact point 30d is L2 and the rotation diameter of the cam pin 13 is L3, the difference between L2 and L3 is the movement amount L1 of the conversion panel 30. Now, the trajectory of the cam groove 30a is set so that L1 is longer than L3 (L2 is set to be longer than twice L3), so the movement amount L1 of the conversion panel 30 is the amount obtained by enlarging the movement amount L3 (rotation diameter) of the cam pin 13. In this way, the rotation diameter of the cam pin 13 is enlarged to become the translation amount of the latch 51. Next, in the second rotation range 10d, the rotation trajectory 12b of the cam pin 13 in FIG. 4(e) and the trajectory of the cam groove 30a coincide with each other. Therefore, in the second rotation range 10d, the conversion panel 30 is in a non-conversion region (idling region), and the conversion panel 30 does not move even if the cam pin 13 rotates from the state in FIG. 4(e) to the state in FIG. 4(f).

[0022] By such a cam locus, the conversion panel 30 moves sufficiently in the first rotation range 10c from FIG. 4(d) to FIG. 4(e), and the latch 51 retreats from the strike 52 and the door C is unlocked. This allows the user to open the door C quickly. And, since the load for moving the conversion panel 30 is not applied to the storage table U10 from FIG. 4(e) to FIG. 4(f), the user can put the storage table U10 in the stable state of FIG. 4(c) with a light operation. If the rotation diameter is increased, the latch 51 can be moved sufficiently without increasing the amount of movement. However, if the rotation diameter is increased, a problem occurs in that the lock-linked object storage table A becomes large. In the present invention, the lock-linked object storage table A can be made compact by devising the cam locus.

[0023] Next, as another problem, for example, when the storage table U10 does not transition from the state shown in Fig. 4(b) to Fig. 4(c) and the door C is closed after leaving the restroom, the storage table U10 may return to the state shown in Fig. 4(a) due to the impact. If the unmanned restroom is locked in this way (herein we call this a "lockout lock"), the manager must take the trouble of unlocking the door C using a special tool.

[0024] When the torque that rotates the storage unit U10 in the direction opposite to the direction of the arrow 10a due to a moment force including impact is called the weight rotation torque, two types of regulating means are prepared as a method of preventing the lockout lock caused by the locking operation due to the weight rotation torque in the present invention. The first regulating means uses friction, which is an adjustment mechanism that sets the friction that resists the weight rotation torque larger than the weight rotation torque. A specific adjustment mechanism sets the friction force between the cam groove 30a and the cam pin 13 larger than the force that moves the conversion panel 30 due to the weight rotation torque. For example, using the idea of ​​the friction angle in cam coupling, when the inclination angle of the cam groove 30a with the cam pin 13 shown in FIG. 4(g) is set to θ, the tangent of the inclination angle θ is set to be smaller than the friction coefficient (static friction or kinetic friction) of the conversion cam by the cam groove 30a and the cam pin 13. In reality, in addition to the friction due to the cam coupling, sliding friction also occurs between the conversion panel 30 and the frame 20 and between the latch 51 and the latch base 50, so the inclination angle θ may be made larger in consideration of these. Alternatively, the frictional force may be adjusted by selecting the material of the conversion cam rather than the inclination angle θ.

[0025] As explained with reference to Fig. 4(e), in the second rotation range 10d, the rotation trajectory 12b of the cam pin 13 and the trajectory of the cam groove 30a coincide with each other. Therefore, no friction due to the cam occurs in the second rotation range 10d, and even if an impact is applied to the storage table U10 in the inverted state shown in Fig. 4(b), the storage table U10 will transition to rotation in the second rotation range 10d. Even if an attempt is made to transition to the first rotation range 10c, the state shown in Fig. 4(a) will not occur due to the influence of the above-mentioned friction, and lockout will not occur.

[0026] FIG. 5 is an explanatory diagram of another example of the lock-linked animal stand A according to the present invention, and the lock-linked animal stand A in FIG. 5 has a second restricting means for preventing lockout. In the perspective view of FIG. 5(a), the storage stand U10 is supported so as to be rotatable 90 degrees around the rotation axis 21a. In addition, the storage stand U10 has a shape that is balanced left and right with respect to the rotation axis 21a, and the storage stand U10 does not rotate around the rotation axis 21a due to imbalance. FIG. 5(b) and (c) are operation explanatory diagrams, and FIG. 5(b) shows the state in which the door C is locked, and FIG. 5(c) shows the state in which the door C is unlocked. In the present invention, the rotation of the storage stand U10 is converted into the translational motion of the latch 51, but there is an advantage in that the relationship between the rotation amount of the storage stand U10 and the translation amount of the latch 51 can be changed by changing the cam locus of the cam groove 30a. Therefore, in the example of FIG. 5, unlike the examples up to FIG. 4, the door C is structured to be opened and closed by a simple operation of rotating the storage table U10 by 90 degrees instead of 180 degrees.

[0027] In the example of FIG. 5(a), the storage table U10 is symmetrical with respect to the rotation axis 21a and has a counter balancer shape that maintains rotation balance, so the torque of rotation by its own weight is extremely small. Therefore, even if the friction of the cam groove 30a is small or the inclination angle of the cam groove 30a with the cam pin 13 is large, the lockout lock will not occur. It is also possible to provide a counterweight 15 as a counter balancer at the end of the storage table U10 on the short side of the rotation axis 21a as shown in FIG. 4(d) even if the storage table U10 is not symmetrical with respect to the rotation axis 21a. In this way, the second restricting means is a torque adjustment means for adjusting the torque of its own weight that reduces the locking force of the lock generated by the torque of rotation by its own weight, and is a counter balancer that moves the center of gravity of the storage table U10 closer to the center of rotation support.

[0028] Furthermore, the problem of lockout occurs not only when the slide latch B is used for locking, but also when the strike lock E is used for locking. Figure 5(e) shows an example in which a storage stand U10 is attached to a strike lock E having a case 60, a rotating part 61, and a locking part 62, and by providing a counterweight 15 to the storage stand U10, the occurrence of lockout caused by the rotational torque of its own weight is suppressed.

[0029] FIG. 6 is an explanatory diagram of the installation of the lock-linked animal stand A on a door C according to the present invention. In FIG. 6(a), the latch 51 is supported on the latch base 50 attached to the door C (not shown) so as to be slidable in the direction of the arrow 51a. Then, the bracket 40 is attached to the surface of the latch 51 with adhesive tape or the like. In FIG. 6(b), the conversion panel 30 and the bracket 40 are screwed together with the screw 40b through the mounting hole 30b and the mounting screw hole 40a. Here, the bracket 40 can be omitted and the conversion panel 30 can be directly attached to the latch 51. However, the conversion panel 30 receives forces in various directions from the cam pin 13, and if the forces are directly transmitted to the latch 51, it will lead to a failure of the slide latch B. Therefore, in the present invention, as explained using FIG. 3, the slide guide 30e of the conversion panel 30 is reliably guided by the frame 20 at the rotation support part U20 so as to be capable of only translational movement, thereby preventing unnecessary forces from being applied to the slide latch B. Also, by configuring the conversion panel 30 and bracket 40 to be screwed together, it is easy to attach the lock-linked animal stand A to the door C. In Fig. 6(c), the frame 20 is screwed to the door C with the screw 20f. (The position of the screw 20f is shown in Fig. 2(c).) In Fig. 6(d), the flange 22b of the top cover 22 is placed over the frame 20. In Fig. 6(e), the top cover 22 is screwed to the door C with the mounting hole 22a and the screw 22c. In this way, the lock-linked animal stand A can be attached to the slide latch B with a simple process. Furthermore, by attaching the top cover 22 so as to cover the conversion panel 30, the conversion panel 30 is protected and the reliability of the attachment of the lock-linked animal stand A to the door C is increased.

[0030] FIG. 7 is an exploded perspective view of a modified example of the present invention, in which the conversion panel 30 provided in the exploded perspective view in FIG. 3 is replaced with a conversion panel 31. The major feature of the conversion panel 31 is that it is provided with a free running area L4 (31f) (FIG. 8). FIG. 8 is an explanatory diagram of the operation of the lock-linked animal stand A using the conversion panel 31, and FIGS. 8(a), (b), and (c) are plan views showing the operation of the lock-linked animal stand A. FIG. 8(a) illustrates a state in which the latch 51 is inserted into the strike 52 and the door C is locked. When the storage stand U10 is rotated from this state in the direction of the arrow 10a in the first rotation range (approximately 90 degrees) 10c, it becomes FIG. 8(b). In the state of FIG. 8(b), the latch 51 is retracted from the strike 52 and the door C becomes unlocked. When the storage stand U10 is further rotated in the direction of the arrow 10a in the second rotation range (90 degrees) 10d, it becomes FIG. 8(c). In FIG. 8(c), the latch 51 is further retracted from the strike 52 than in FIG. 8(b), and the inverted and unstable state of FIG. 8(b) is changed to a stable state.

[0031] 8(d), (e), and (f) are plan views of the conversion panel 31 explaining the cam locus, and correspond to the states of the lock-linked animal stand A in FIG. 8(a), (b), and (c), respectively. When moving from the state of FIG. 8(d) to the state of FIG. 8(e), the conversion panel 31 moves by L1, and when moving from the state of FIG. 8(e) to the state of FIG. 8(f), the conversion panel 31 also moves by L1. Here, in the state of FIG. 8(e), the cam pin 13 is located in the free running area L4 (31f) of the cam groove 31a. The width L5 (31h) of the cam groove 31a in the free running area L4 is set larger than the cam pin movement width L6 (31i) in the free running area in the rotation locus 12b, and the width L5 (31h) of the cam groove 31a in the free running area L4 is larger than the width L7 (31j) of the cam groove 31a other than the free running area L4. Therefore, when the cam pin 13 is located in the free running region L4, the conversion panel 31 is free relative to the cam pin 13, and the latch 51 can move translationally in the direction of the arrow 51a independently of the movement of the storage table U10.

[0032] The reason for providing the free running area L4 (31f) in the conversion panel 31 will be explained. Returning to FIG. 1, consider the case where the storage table U10 is rotated without the door C being fully closed. At this time, the latch 51 collides with the frame 52a of the strike 52 (FIG. 9(a)) or the edge of the support D, and the movement is restricted. However, the storage table U10 has a long rotating arm, and a large stress is applied to the latch 51, causing the adhesion between the latch 51 and the bracket 40 to shift. Such a phase shift in adhesion between the latch 51 and the bracket 40 results in a "failure to interlock" in which the door C cannot be locked even when the storage table U10 is rotated. (The door C is not locked even in the state of FIG. 8(d).) As explained using FIG. 2(b) and (c), if the adhesion between the latch 51 and the bracket 40 is peeled off, the latch 51 can be locked and unlocked by directly applying a force to the latch 51 in the direction of the arrows 51b and 51c. However, in the case of adhesive phase misalignment rather than peeling, the storage platform U10 and the latch 51 are interlocked while still out of phase, so the storage platform U10 becomes a load and it becomes difficult to directly operate the latch 51. Therefore, in the present invention, the storage platform U10 is returned from the state of Fig. 8(a) to the state of (b) to position the cam pin 13 in the free running area L4 (31f), and then a force is applied from the notch 20g in the direction of the arrow 51b to lock the door C. The length of the free running area L4 is set sufficiently larger than the movement amount L1 of the conversion panel 31 (double L1 in Fig. 8(e)), so the latch 51 can be inserted into the strike 52 within that area.

[0033] Another advantage of providing the free running area L4 (31f) is maintainability. When inspecting the sliding state of the latch 51, it is necessary to operate the latch 51 with the load on the lock-linked object stand A set to zero. In such a case, the sliding state can be inspected by palpating the latch 51 through the notch 20g after placing the stand U10 in the state shown in FIG. 8(b).

[0034] Adjustment cams 31g are provided at both ends of the free running area L4 (31f). If the cam pins 13 in the cam groove 31a are arranged as shown in FIG. 8(e), the cam pins 13 can move in the entire area of ​​the cam groove 31a even without the adjustment cams 31g. However, if the latch 51 is moved directly from the notch 20g, the arrangement of the cam pins 13 in the cam groove 31a will be different from that shown in FIG. 8(e) (for example, FIG. 8(g)). In such a case, the storage table U10 is rotated in the direction opposite to the arrow 10a to guide the cam pins 13 with the adjustment cams 31g, so that the latch 51 can move in the unlocking direction. In other words, the latch 51 is directly pressed to lock the door C, but the door C can be unlocked by rotating the storage table U10.

[0035] As a method for preventing the lockout even in the conversion panel 31, when the inclination angle between the cam groove 31a and the cam pin 13 shown in Fig. 8(h) is set to θ, the tangent of the inclination angle θ is set to be smaller than the friction coefficient (static friction or kinetic friction) of the conversion cam formed by the cam groove 31a and the cam pin 13. In reality, in addition to the friction due to the cam connection, sliding friction also occurs between the conversion panel 31 and the frame 20 and between the latch base 50 of the latch 51, so the inclination angle θ may be made larger in consideration of these. Alternatively, the friction force may be adjusted by selecting the material of the conversion cam rather than the inclination angle θ.

[0036] As mentioned above, if the storage unit U10 is rotated without the door C being fully closed, the movement of the latch 51 is restricted, causing an interlocking failure in the lock-linked storage unit A. As a countermeasure to this, the present invention provides the notch 20g and the free running area L4 (31f). Instead of measures to be taken after such an interlocking failure, measures to prevent the interlocking failure from occurring will be described with reference to FIG.

[0037] 9(a), a position restriction surface 41c is provided as a means for preventing interlocking failure at the end of the bracket 41. Since the position restriction surface 41c abuts against an end surface 51d of the latch 51, even if stress is applied from the direction of the arrow 51e, the adhesive phase shift between the latch 51 and the bracket 41 will not occur.

[0038] 9(a), a stress absorbing spring is provided between the bracket 41 and the conversion panel 32 as a means for preventing misalignment, and even if the storage table U10 is forcibly rotated when the latch 51 is not moving, the force is absorbed by the spring. Specifically, a coil spring portion 42a of a stress absorbing spring such as a torsion spring 42 is hooked on a spring hook 41d of the bracket 41. A pressing end 42c of the torsion spring 42 is hooked on a pressing hook 41f of the bracket 41, and a charging end 42b is hooked on a charging hook 41e in a charged state. The long mounting hole 41a of the bracket 41 and the mounting screw hole 32b of the conversion panel 32 are screwed together with a screw 41b that penetrates the guide bush 25.

[0039] One of the pair of guide bushes 25 is inserted into a hole surrounded by the mounting elongated hole 41a and the charging end 42b in the charging direction. Therefore, the conversion panel 32 and the bracket 41 can elastically slide in the longitudinal direction of the mounting elongated hole 41a. When the storage table U10 is rotated and the conversion panel 32 moves in the direction of the arrow 51f (the door C lock direction), the guide bush 25 pushes the charging end 42b in the direction of the arrow 51f. As a result, the bracket 41 also moves in the direction of the arrow 51f, and the latch 51 is inserted into the strike 52. (The door C is locked.) When the latch 51 collides with the frame 52a of the strike 52 and cannot move in the direction of the arrow 51f, the charging end 42b bends and the guide bush 25 slides in the mounting elongated hole 41a. Therefore, the conversion panel 32 can continue to move in the direction of the arrow 51f. In this way, a mechanism is provided in which the rotational force of the storage stand U10 is absorbed by the stress absorbing spring, so that malfunction of the lock-linked storage stand A due to unintentional operation can be prevented.

[0040] FIG. 9(b) shows an example in which a stress absorbing spring is provided on the rotating table of the storage table U10 as a means for preventing linkage failure. The rotation stopper shaft 16 provided on the first table 18 and connected to the tray 10 and the back cover 11 with the retaining groove 16a does not extend to the cam groove 32a of the conversion panel 32, unlike FIG. 7. Instead, the cam pin 17 provided on the second table 19 is inserted into the cam groove 32a of the conversion panel 32. The first table 18 and the second table 19 are supported by the shaft 21 penetrating the shaft holes 18a and 19e so as to be rotatable around the axis of the shaft 21. The coil spring portion 43a of a stress absorbing spring such as a torsion spring 43 is fitted into the spring core 19a of the second table 19. The pressing end 43c of the torsion spring 43 is received by the pressing hook 19c, and the charging end 43b is hung on the charging hook 19b in a charged state. The action pin 18b of the first table 18 is inserted into the arc hole 19d of the second table 19.

[0041] The action pin 18b is inserted into a hole surrounded by the arc hole 19d and the charge end 43b in the charge direction. When the storage table U10 is rotated in the direction of the arrow 10b (door C lock direction), the first table 18 rotates in the direction of the arrow 10b, and the action pin 18b pushes the charge end 43b in the direction of the arrow 10b. This causes the second table 19 to rotate in the direction of the arrow 10b, and the latch 51 is inserted into the strike 52 by the action of the cam pin 17 and the cam groove 32a. (Door C is locked.) When the latch 51 collides with the frame 52a of the strike 52 and the second table 19 cannot rotate in the direction of the arrow 10b, the charge end 43b is deflected and the action pin 18b slides in the arc hole 19d. Therefore, the first table 18 can continue to rotate in the direction of the arrow 10b. In this way, a mechanism is provided in which the rotational force of the storage stand U10 is absorbed by the stress absorbing spring, so that malfunctions of the lock-linked storage stand A due to unintentional operation can be prevented.

[0042] As described above, the lock-linked animal storage stand A is used by being attached to the latch 51 of the slide latch B equipped on the door C or the support D, and is composed of the storage stand U10, the rotation support part U20 that rotatably supports the storage stand U10, the conversion part U30 that converts the rotational motion of the storage stand U10 by the rotation support part U20 into translational motion, and the transmission part U40 that transmits the translational motion converted by the conversion part U30 to the latch 51, and the latch 51 is operated by rotating the storage stand U10. In addition, a restricting means is provided that restricts the locking operation of the slide latch B or the striking lock E due to the self-weight rotation torque of the storage stand U10. Furthermore, a control means is provided that can operate the latch 51 independently of the rotation of the storage stand U10. Furthermore, a linkage failure prevention means is provided that eliminates linkage failure caused by the movement of the latch 51 being restricted. As a result, a lock-linked animal storage stand A with high operability has been realized. [Industrial Applicability]

[0043] The present invention has a structure in which the lock-linked storage stand A is attached to a slide latch B provided on the door C or support D, so it can be applied to private rooms equipped with the widely used slide latch B. In addition, since the slide latch B can be moved by rotating the lock latch B, the force required to lock and unlock the door C can be reduced, making public toilets barrier-free. Note that if the purpose is to reduce the operating force, the effect of the present invention is great even if a rotating knob is provided instead of the storage stand U10. [Explanation of symbols]
