Description

The present invention relates to a storage device that can secure a maximum opening at the time of opening as much as possible when arranging a plurality of sliding doors in an opening of a housing so that the sliding doors can be pulled apart.

As this type of locking device, for example, a device disclosed in Patent Document 1 is known. In this structure, a plurality of sliding doors are associated with each other through a related mechanism between an open state where they overlap each other and a closed state where the polymerization is almost eliminated, and a lock for holding the sliding doors in a closed state. Is provided in part.

Specifically, it has an interlocking member that associates three sliding doors so that they can be interlocked, and one end of the interlocking member rotates in a closed state among the sliding doors located on the back side more than the edge adjacent to the other sliding doors. It is pivotably attached, and the intermediate part and the other end part of the interlocking member are slidable up and down via a roller on the guide part provided respectively from the same edge part of the sliding door located in the middle and the sliding door located on the front side. A roller that moves together in the guide portion of the sliding door by aligning and operating a locking member that protrudes on the back side when the lock is operated by disposing the lock in the proximity of the guide portion in the sliding door located on the front side An engaging member is engaged with the support shaft of the shaft to prevent the interlock member from moving upward.

Thus, the thing of the patent document implement | achieves the fully closed and fully open state effectively only by operating the sliding door of an edge part. Further, by prohibiting the operation of the sliding door by restraining the related mechanism, it is not necessary to make a separate step on the housing side for locking.

However, in such a structure, since the locking member protrudes on the back surface of the lock, when the front sliding door is opened, the sliding doors cross over the position where the locking member interferes with the adjacent intermediate sliding door. It cannot be moved relative. For this reason, it is inevitable that an undrawn portion is generated between the sliding door on the front side and the intermediate sliding door, and this is a factor that limits the maximum opening. Although it is possible to accommodate the part of the locking member by bulging the face plate part of the sliding door forward, thereby avoiding the above interference, the appearance is damaged and the interference is completely eliminated. It is difficult.

Moreover, since the thing of the said patent document 1 is a structure which restrains the supporting shaft of a roller directly by the locking member of a lock, when a sliding door is forcibly operated in the opening direction in a locked state, it is impossible for a support shaft or a lock. There is also a problem that a heavy load is easily applied.

Further, the above-mentioned locking member restrains the rotation operation of the interlocking member by applying a vertical surface to the support shaft, but the rotation operation of the interlocking member when in a posture close to the horizontal is horizontal. Rather, the vertical direction has a larger velocity component, so even if the horizontal direction is restricted, it is easy for backlash to remain in the up and down direction, which adds to the load on the spindle and lock and reduces the quality of the storage device. Is easy to connect.

FIG. 2 shows the three sliding doors from the back side. The lock device A is associated with each sliding door 1 by the related mechanism 5 on the back surface, and is located on the right side because it is reversed in FIG. 2 (hereinafter, FIG. 3 and FIG. 5). The related mechanism 5 is constrained by the locking mechanism 6 provided in FIG. 8), and the locked state of the three sliding doors 1 to 3 is realized.

As shown in FIGS. 2 to 4, the related mechanism 5 forms guide rails 24 and 34 that are vertically extending guide portions 24 and 34 on the respective rear surfaces of the intermediate sliding door 2 and the sliding door 3 located on the rear surface side. One end portion 51a of a long interlocking member 51 formed by bending a part is attached to the rear surface of the sliding door 1 positioned on the front side so as to be rotatable around the support shaft m1, and is attached to the intermediate portion 51b via the support shaft m2. The roller 52 is engaged with the guide rail 24 of the intermediate sliding door 2 so as to be vertically slidable, and the roller 53, which is a rotor attached to the other end 51c via the support shaft m3, is attached to the guide rail 34 of the rear sliding door 3. They are slidable up and down. The mounting position of the one end 51a is from the edge 11 on the opposite side of the edge 12 adjacent to the intermediate sliding door 2 in the sliding door 1 on the front side, and the positions of the guide rails 24, 34 are also the respective sliding doors 2, 3 is set from the edge portions 21 and 31 on the same side. The imaginary line connecting the one end portion 51a and the other end portion 51c of the interlocking member 51 when the sliding doors 1 to 3 are in a closed state is set in a state inclined to approximately 15 ° to 20 ° with respect to the horizontal, The intermediate part 51b is located on the virtual line.

On the other hand, as shown in FIGS. 1 to 3, the locking mechanism 6 includes a lock 61 as a locking portion attached using a reinforcing portion formed on the back surface of the face plate portion of the sliding door 3 positioned on the back side in the depth direction, and the back surface. It consists of a restraining portion 62a provided at a position engaging with the related mechanism 5 on the back surface of the sliding door 3 on the side, and a transmission portion 63 for transmitting the operating force input to the lock 61 to the restraining portion 62a.

In this embodiment, the lock 61 is a cylinder lock type, and the dead bolt 61a is moved up and down on the back side of the sliding door 3 by a key operation. The restraining portion 62a is formed on a part of the locking member 62 rotatably attached to the support shaft m4 set on the guide rail 34 of the sliding door 3 on the back side and in the vicinity of the lower end thereof. The member 62 has a substantially crank shape using a steel plate, and an intermediate portion thereof is rotatably supported by the support shaft m4. The tip portion displaced from the support shaft m4 has a hook shape to form the restraining portion 62a. ing.

The transmission part 63 is attached to a first link 64 having one end 64a connected to the dead bolt 61a and the other end 64b hanging substantially vertically downward, and is rotatably attached to the back surface of the sliding door 3 on the back side around the support shaft m5. A second link 65 connecting the other end 64b of the first link 64 and the base end portion 62b displaced from the support shaft m4 of the locking member 62 is provided. That is, when the first link 64 is driven up and down by the dead bolt 61a in accordance with the operation on the lock 61, the locking member 62 is rotated while the second link 65 is rotating, and the restraining portion 62a is moved to the interlocking member 51. Near the other end 51c, a nearly horizontal operation is given between the open position in FIG. 3 and the restrained position in FIG.

And in this embodiment, the rib 51r bent to the back surface side is formed as a lock receiving part in the rigid body part displaced from the other end part 51c to which the roller 53 is axially attached among the interlocking members 51 as shown in FIG. Then, the upward surface 51d of the rib 51r is set as a locked portion with which the locking portion 62a of the locking member 62 is engaged, and at a predetermined position in the guide rail 34 from the groove bottom of the guide rail 34 to the back surface side. A tongue-like support portion 34a that rises is provided. That is, when the other end portion 51c of the interlocking member 51 is lowered downward in the closed state of the sliding doors 1 to 3, the roller 53 is supported by the support portion 34a, and the lock 61 is operated at that position. As shown in the figure, the restraining portion 62a enters above the upward surface 51d at substantially the same position in the thickness direction of the sliding door 3, and the upward movement of the interlocking member 51 is restricted by the downward surface 62ax, and the sliding doors 1 to 3 are locked. I try to keep it in a state.

On the other hand, when the latch 33 is released by operating the handle 33 of the sliding door 3 on the back side shown in FIGS. 3 and 6 in the unlocked state, and operating in the opening direction as it is, both rollers 52 and 53 respectively correspond to the corresponding guide rails 24. , 34, the rollers 52, 53 move upward along the guide rails 24, 34 as the interlocking member 51 rotates about the support shaft m1. Then, as shown in FIG. 3 to FIG. 8 and FIG. 9 to FIG. 10, the opening of the housing 4 is opened, and the sliding doors 1 to 3 are almost overlapped at the maximum opening position.

In this case, it is avoided that the support shaft m1 interferes with the intermediate sliding door 2 and the support shaft m2 with the rear side sliding door 3, respectively, and the edges 11, 12, and 13 of the sliding doors 1 to 3 are substantially aligned. In order to make the interlocking member 51 of this embodiment, as shown in FIG. 11, one end 51a and an intermediate part 51b are brought out at positions displaced from the steel plate main body 51x in the thickness direction. The one end portion 51a and the intermediate portion 51b have a parallel plate shape. As shown in FIGS. 12 and 13, the interlocking member 51 has one end portion in a state where the support shafts m1, m2, and m3 are substantially aligned (that is, the guide rails 24 and 34 and the rollers 52 and 53 are approximately aligned). 51a from the sliding door 1 located on the front side and the sliding door 2 located in the middle through the gap between the sliding doors 1 and 21 is taken out of the edges 11 and 21, and the middle portion 51b is located on the rear side and the sliding door 2 located in the middle. Inserted into a position corresponding to the guide rail 24 of the sliding door 2 located in the middle through the clearance of the sliding door 3 and the other end 51c inserted into a position corresponding to the guide rail 34 of the sliding door 3 located on the back side. It is trying to become.

In addition, about the edge parts 12, 22, and 32 of an other side, as shown in FIG. 10, although the sliding door 12 located in the front side and the sliding door 22 located in the middle will be in the state substantially aligned, it is located in the back side. In the relationship between the sliding door 3 and the intermediate sliding door 2, if these edge portions 22 and 32 are completely overlapped, the handle 33 of the rear sliding door 3 cannot be operated. A required unacceptable d is provided.

The lock device A of the present embodiment configured as described above is configured such that a plurality of sliding doors 1, 2, and 3 are connected via an associated mechanism 5 between an open state in which the plurality of sliding doors 1, 2, and 3 are overlapped with each other and a closed state in which the overlap is substantially eliminated. When the locking mechanism 6 for holding the sliding doors 1 to 3 in a closed state is provided, the locking mechanism 6 is provided on the face plate portion of the sliding door 3 located on the back side in the depth direction. The lock 61 is provided with at least a restraining portion 62 a that is provided on the back surface of the sliding door 3 on the back side and is operated by an operation input to the lock 61 to restrain the related mechanism 5.

In this way, by operating the sliding doors 1 and 3 at the ends, the fully closed and fully opened states can be effectively realized through the relative movement of the sliding doors 1 to 3, and the sliding door 1 can be realized through the restraint on the related mechanism 5. Since the operations of .about.3 are prohibited, it is possible to eliminate the need for special preparation on the housing 4 side for locking. And as the structure for that, since the lock 61 is provided in the sliding door 3 on the back side and the related mechanism 5 is constrained from here, at least the intermediate sliding door adjacent to the edge 11 of the sliding door 1 on the front side at the time of opening. It is possible to remove the cause of the undrawn portion between the two edge portions 21 without causing the face plate portion to bulge, and without damaging the appearance as compared with the configuration in which the lock 61 is provided on the front sliding door 1. The maximum opening can be effectively secured.

In this case, the related mechanism 5 is attached at least to the sliding door 1 positioned on the front side in the depth direction so that the one end 51a can be rotated and the other end 51c can be slid up and down on the guide portion 32 provided on the sliding door 3 on the back side. Since the interlocking member 51 is mainly used, the structure is simple and the movement is smooth, and if the weight of the interlocking member 51 is used, an automatic closing function can be easily provided.

And since the locking mechanism 6 is restraining the upper surface 51d of the rib 51r which is the site | part displaced from the other end part 51c of the interlocking member 51 by the restraint part 62a, the sliding doors 1 and 3 open in a locked state. It is possible to effectively avoid an unreasonable load from acting on the other end 51c that bears the slide function when operated in the direction.

In particular, in this embodiment, the other end portion 51c of the interlocking member 51 has a roller 53 that is a rotor that can rotate around the support shaft m3, and the roller 53 is engaged with the guide rail 34 that is a guide portion so as to be slidable up and down. At the same time, the upward surface 51d of the rib 51r, which is a rigid portion of the interlocking member 51 displaced from the support shaft m3, is restrained by the restraining portion 62a, so that the support shaft m3 and thus the smoothness of the operation are secured. The roller 53 can be effectively protected from damage due to the load.

In this case, a support portion 34a is provided at a position that supports the weight of the other end side of the interlocking member 51 in the closed state of the sliding doors 1 to 3, and the interlocking member 51 is supported on the support portion 34a. Since the moving operation is restrained by the restraining portion 62a, the weight of the interlocking member 51 is shared and supported by the support portion 34a, and the restraining portion 62a restrains only the substantial upward motion of the interlocking member 51. In this way, the load applied to the restraining portion 62a can be reduced, and an appropriate locked state can be realized without difficulty.

Further, the interlocking member 51 is configured to take a posture close to horizontal when the sliding doors 1 to 3 are closed, and the rotation of the interlocking member 51 when in the posture close to horizontal is a speed in the vertical direction rather than the horizontal direction. Focusing on the point that the component is large, the restraining portion 62a is configured to restrain the upward movement of the interlocking member 51 by the downward surface 62ax, so that there is some assembling error or the like in the interlocking member 51. In addition, the sliding doors 1 to 3 can be locked with little play. Specifically, the ratio of the speed component at the inclination angle of 15 ° to 20 ° is vertical movement: horizontal movement = approximately 3: 1, and the sliding door even if the interlocking member 51 slightly moves up and down due to rattling at the time of locking. The horizontal movement of 1 to 3 hardly appears.

By the way, when attaching the one end part 51a of the interlocking member 51 to the sliding door 1 located on the front side, the supporting shaft m1 protrudes on the back surface of the sliding door 1, but the intermediate sliding door 2 adjacent to the supporting shaft m1. In this embodiment, as described above, the support shaft m1 is rotatably attached to the edge 11 opposite to the edge 12 adjacent to the intermediate sliding door 2 so as not to interfere with the edge 11. In this case, when the other end 51c of the interlocking member 51 is extended to the edge 12 opposite to the edge 11 where the support shaft m1 is provided in the sliding door 3 located on the back side together with the lock 61, the interlocking member 51 is provided. Becomes longer, the turning radius becomes larger, the guide rails 24 and 34 become longer, and a sliding door with a low height causes a problem in the maximum opening. On the other hand, in this embodiment, one end portion 51a of the interlocking member 51 is closed from the edge portion 11 on the opposite side to the edge portion 12 adjacent to the intermediate sliding door 2 in the closed state among the sliding doors 1 positioned on the front surface side. At the same time, the other end 51c of the interlocking member 51 is engaged with the guide rail 34 provided on the same side of the sliding door 3 located on the back side so as to be slidable up and down. The dimension of the interlocking member 51, that is, the turning radius can be effectively suppressed.
