Description

[Detailed description of the invention] This invention relates to the improvement of the sliding door device of the storage body, and its purpose is to install a steel or glass plate sliding door or a hinged door at the front edge of the storage body opening of a certain standard size. When installing a steel sliding door at the front of the storage unit in a storage unit that can be selectively installed, the thickness of the sliding door must be regulated so that it does not exceed a certain level, and a glass plate sliding door or hinged door is installed. Similarly, it can be attached between upper and lower rails that are installed in grooves of a predetermined size on the upper and lower front edges of the opening of a storage body which is opened at the front.

Conventionally, sliding doors other than glass plate sliding doors, especially steel sliding doors, have been provided with a locking device on the back side of the front sliding door so that they can be locked into the locking hole in the rear sliding door, and the components that make up the locking device are It is impossible to make the front sliding door more compact than a certain level due to mechanical and manufacturing reasons, so the front sliding door has to be extremely thick compared to the rear sliding door because it covers the locking device, and from an external perspective. Since the rear sliding door is made to have the same thickness as the front sliding door, it is impossible to install a sliding door with a locking device on the front edge of the opening, which has been regulated to a certain size in advance to allow the installation of glass plate sliding doors and hinged doors. The dimensions of the edges had to be made longer in the front, and as a result, when storage units with the same standard dimensions were installed in parallel, only the storage unit with the sliding door with a locking device protruded forward, which was unfavorable in terms of indoor layout. .

This proposal was devised to eliminate the above-mentioned drawbacks, and the main point is that in sliding doors with a locking device, by providing a locking device on the back side of the rear sliding door of the front and rear sliding doors, it is possible to lock the sliding door. This eliminates the need to cover the locking device in a box shape, and allows the front sliding door as well as the rear sliding door to have any thickness, making it possible to install it on the front edge of the opening of a storage body with standard dimensions. At the point.

To explain the embodiment with reference to the attached drawings below, the rear sliding door 1 has a reinforcing rib 2 formed by bending one side (front sliding door side) and the upper edge, and the other side has a reinforcing rib 2 formed inside the opening of the storage body A when closed. A folded piece 4 is formed to come into contact with the door stop 3 on the front edge side, and a locking device B consisting of a suitable interlocking mechanism is provided on the back side. For example, an actuating plate 6 is connected to a lock 5 attached to the back surface of the other side, one end of a connecting rod 7 is rotatably or fixed to the actuating plate 6, and a bent piece 8 formed at the other end is attached to the rear sliding door. 1. One end of the lock member 9 is rotatably provided on one side of the rear surface (the side where the front sliding door and the joint part are connected). When the lock 5 is operated, the lock member 9 is rotated via the actuating plate 6 and the connecting rod 7, and the other end of the lock member is bent to form an opening 12 on one side of the rear sliding door 1. This hook 9' can be fitted into a locking hole of a locking plate 13 provided on the back side of the side end of the front sliding door 1', so that both sliding doors 1, 1' can be moved forward and backward. It can be locked and closed. The lock member 9 is a hole 1 formed in a bent piece 15' of a support plate 15 welded and fixed to the back surface of the rear sliding door 1.
The bent mounting pieces 9'' and 9'' of the locking member 9 are fitted to the bent pieces 6 and 16, and the connecting rod 7 is provided by penetrating the bent piece 15' of the support plate 15. The piece 15' is further formed into an extended bent piece as shown by the dashed line in the figure, and a coil spring 17 is interposed between the extended bent piece and the lock member 9, so that the lock member 9 is kept open so that its hook 9' is always open. 1
The locking device B may be biased in the direction of protruding from the locking device 2, and the locking device B is not limited to the above-mentioned configuration, and may be a locking device of various mechanisms. Note that 18 in FIG. 1 indicates the rails provided in the grooves formed above and below the front edge A' inside the opening of the storage body A.
9 is a back support plate attached to the back side of the lock.

According to the storage sliding door of the present invention as described above, since the locking device B is provided on the rear surface of the front and rear sliding doors, even if the locking device has a bulky shape, this Since the locking device cannot be seen from the outside even if the rear sliding door is not covered with a back plate, the length of the bending rise of the reinforcing rib 2 of the rear sliding door 1, that is, the thickness of the rear sliding door 1 has nothing to do with the locking device. Also, since nothing is attached to the back of the front sliding door 1', it can be made to any thickness. Therefore, it cannot be locked like a conventional sliding door with a locking device. The thickness of the front sliding door installed with the device becomes large and is extremely different from the thickness of the rear sliding door, spoiling the appearance, or the front edge of the opening of the storage body whose thickness is unified to a certain standard size. A storage body that has fixed dimensions and is designed to allow installation of a steel sliding door with a steel locking device, a glass plate sliding door, or a hinged door without causing any drawbacks such as the impossibility of installation in part A'. It can be attached to the front edge A' inside the opening. Moreover, by providing the locking member 9 on the back side of one side (front sliding door side) of the rear sliding door 1 and installing the lock 5 on the back side of the other side, even though the locking device is provided on the back side of the rear sliding door 1, , lock 5
The front sliding door 1' and the rear sliding door 1 can be opened and closed in the lateral direction with the key inserted in the front sliding door, and opening and closing operations can be performed in the same way as when a conventional front sliding door is provided with a locking device.
