[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door locking device for a sliding door such as a cabinet, in which the lock is provided at either the left or right end of the door.

[0002]

[Prior Art]

 As a conventional locking device for a sliding door in furniture or the like, there is known a device in which a lock is provided at a central portion when the inner and outer doors are closed.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned prior art, especially in the case of a large cabinet, if there is a lock at the center of the outer door where the outer door overlaps, the puller is attached to the end even when unlocked. There was a problem that I had to move and use the puller to open the door. Also, if a lock is attached to the central part where the inner and outer doors overlap, the thickness of the door cannot be reduced by any means, and in order to increase the number of types of locks in particular, the door must be made thicker. Due to this, when the outer dimensions are the same, the inner dimensions cannot be widened, resulting in a problem that the inner volume is reduced. In view of this point, the present invention has a simple structure in which the lock is provided at the outer end of the outer door when the door is closed, and the key plate is pivoted by the locking operation of the lock to close the center when the door is closed. The inner and outer doors are locked by engaging a key plate stopper provided on the other end of the inner door, and a lock is provided near the puller, so the door can be opened and closed smoothly. It is an object of the present invention to provide a door locking device for furniture that can be used.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and in a locking device for a sliding door in furniture or the like, a puller and a lock are provided on the end side when the outer door is closed. A key plate that can be rotated by an appropriate angle by turning the lock is provided extending from the end part to the center part, and when other inner doors are closed, a key plate stop is provided on the center side, and the lock, key plate, and key plate are provided. We adopted the technical means of enabling the outer door and inner door to be locked and unlocked by locking.

[0005]

[Action]

 According to the present invention, by adopting the above technical means, the lock for locking and unlocking is provided near the puller of the door on the end side when the door is closed with a simple structure. This makes it easier to open and close the door, and especially when holding items, it is much easier to open and close than the conventional technology.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic perspective view showing a closed state of a sliding door type bookshelf which is an embodiment. 1 is a main body top plate, 2 is a main body side plate, 3 is an outer door, 4 is an inner door, 5 Is a puller, 6 is a lock, 7 is a key plate, 8 is a first key plate contact, 9 is a second key plate contact, 10 is a key plate stopper, and the outer and inner doors 3 and 4 can slide left and right. In this embodiment, the lock 6 is provided near the puller 5 at the right end. Next, one embodiment of a specific configuration of the lock 6 provided on the outer door 3 and the key plate 7 will be described in detail with reference to FIG. FIG. 2 is an exploded view of each member, and a key plate receiver 12 is fixed to an appropriate position on the back side portion 11 of the outer door 3 by appropriate spot welding or the like. Then, the key plate 7 having an approximately U-shaped cross section provided with an engaging hole 14 so that it can be engaged with the loose fitting insertion projection 13 of the key plate receiver 12 is loosely inserted as shown in the drawing. The key plate 7 has a first hole portion 17 for attaching a first key plate pad 8 made of an elastic material such as a resin or a synthetic rubber for softening a metallic sound at an end portion 15 on the lock 6 side. And the other end 16 is formed with a second hole 18 to which a second key plate contact 9 made of the same material as the first key plate pad 8 is attached. The first key board pad 8 is provided with an inclined portion 20 so that the key board 7 can be pivotally moved upward by the dead bolt 19 of at least the lock 6, and the second key board pad 9 has a keyed portion at the end thereof. A locking surface 21 for engaging the plate stopper 10 is provided. Needless to say, the lock 6 can be variously selected as long as it is a lock provided with a commercially available dead bolt, and can be attached near the pull tab 5. FIG. 3 shows the above-described assembly assembled and unlocked. As shown, the loose fitting insertion projection 13 of the key plate receiver 12 fixed to the back side 11 of the outer door 3 is shown. The key plate 7 is assembled by being inserted loosely into the engagement hole 14 of the key plate 7 and being rotatable by the dead bolt 19 of the lock 6. A key plate stopper 10 is fixed to the front end of the inner door 4. This may be an appropriate fixing means, for example, a hole is formed at the end of the outer door 3 and one end of the key plate stopper 10 is inserted and spot-welded to fix it. It is possible to design a product in which the existing part is bent to provide a locking part. FIG. 4 shows the locked state. As shown in the figure, the key plate 7 is held in the key plate receiver 12 in a free state, and when the lock 6 is locked, the dead bolt 19 is rotated upward, The key plate 7 is rotated upward through the inclined portion 20 of the first key plate pad 8, and the second key plate pad 9 is locked to the key plate stopper 10 provided at the end of the inner door 4. It keeps the door closed.

[0007]

[Effect of the device]

 The present invention can obtain the following effects based on the above configuration. (1) Conventionally, when the sliding door is closed, since the lock is attached to the portion where the inner and outer doors overlap, the lock is attached to the portion where the thickness of the door becomes thicker. Narrows. On the other hand, in the case of the present invention, when the sliding door is closed, the lock is attached near the pull handle on the end side of the outer door where the inner and outer doors do not overlap, so that the door is thin Since it will be locked, the inner dimensions can be made wider than conventional ones. (2) Compared with the conventional one, when the sliding door on the outside is closed, a lock is provided at the non-overlapping end, so that the types of locks that can be used can be increased.
