  However, the lock body and the receiving portion require a certain amount of built-in dimensions in the depth direction. When the sliding doors move relative to each other, the lock body of the front sliding door passes in front of the rear sliding door, and the receiving portion of the rear sliding door passes through the back surface of the front sliding door. For this reason, in order to properly incorporate them, and to prevent the lock body or the receiving part from interfering with the rear or front sliding door, the vertical wall or the sliding door is thickened, or the sliding door is longer than the distance from the lock body to the receiving part. A clearance must be secured in between. Therefore, the entire surface of the sliding door is lowered and the appearance is impaired, giving a heavy impression, and if the sliding door has a function such as a white board, the locking material is not provided because the face material is thin in the first place. There was nothing else to do. In addition, when applied to an open storage or the like, the gap between the front sliding door and the side plate of the housing becomes large at the time of closing according to the clearance between the sliding doors, so that the structure for concealing this is also large. It was inconvenient.

There are cases where it is configured. In such a case, as another embodiment, the lower eaves 2c (3c) is configured only by the eaves main bodies 21 and 31 without using the end eaves or the corner members, and as shown in FIG. 6 is attached to the portion to be the summing portion of 3, ie, the vicinity of the end portion of the heel body 31 which is the lower heel 3c, and the lock body 5 shown in FIG. 9 is a portion facing the continuous recess 2x of the rear sliding door 2 shown in FIG. 9 where the operating rod 51 arrives at the summoning, that is, a portion provided near the end of the rod main body 21 that is the lower rod 2c. It may be selectively inserted into the portion 106. The mounting hole 105h shown in the figure is drilled in the upright surface of the recessed portion 31c of the frame portion 31b having a U-shaped cross section of the bag main body 31, but the distance to the receiving portion 106 is considered when the lock body 5 is assembled. Needless to say, a spacer or the like can be interposed as required. The receiving part 106 is perforated on the downward surface of the frame part 21b having a U-shaped cross section of the bag main body 21.

Even in this configuration, the same state of incorporation as shown in FIG. 7 is obtained, and the lock body 5 (particularly the engaging portion 51b) of the front sliding door 3 and the face material 2a of the rear sliding door 2 are superposed with each other. Even if it becomes, like the said embodiment, the sliding doors 2 and 3 can be moved relatively without interfering with each other, and it is not influenced by the thickness of the face materials 2a and 3a of these sliding doors 2 and 3 By incorporating the key body 5 and the receiving portion 106 into the sliding doors 2 and 3, the clearance between the front and rear sliding doors 2 and 3 can be minimized. As described above, the end wall and the corner member are not indispensable requirements. If the sliding door has an upper or lower wall, a continuous recess and a receiving part are secured on the rear sliding door wall, and the front sliding door wall is secured. Since the present invention can be implemented simply by incorporating the lock body into the predetermined relationship, the present invention can be widely applied to various sliding doors. Of course, the face material and the ridge may be integrated.

In the above embodiment, since the structure for locking the upper storage portion is adopted, the locking structure of the present invention is applied to the lower arm, but the operability is considered when the housing of the storage portion is placed directly on the floor. Thus, the locking structure of the present invention is preferably applied to the upper collar. In this case, the present invention can be applied to the upper eyelid if the structure of the sliding doors 2 and 3 is turned upside down including the positions of the continuous recess, the lock body, and the receiving portion of the illustrated embodiment.

In the above embodiment, the sliding door has a whiteboard function. However, even if the sliding door is a simple decorative board or the like, the same effects as described above can be obtained.

Furthermore, in the above embodiment, the operating rod is provided with an engaging portion at a position displaced laterally from the lock body via the take-out portion. You may position an engaging part in the back of a lock main body.

Furthermore, the present invention can be applied to a storage device other than the open storage structure as described above, and also includes a case where the side of the sliding door is made of wood, etc., without departing from the spirit of the present invention.
