DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a hanging door in a building or furniture.

[0002]

2. Description of the Related Art A conventional hanging door suspended from a door so as to be slidable left and right is disclosed, for example, in Japanese Utility Model Publication No. Sho 62-548.
As shown in Japanese Patent Publication No. 2, since all the mechanical parts of the locking device are mounted in the hanging door, the hanging door is thick and heavy, and it is not easy to slide it smoothly. In particular, it is difficult to make the door thin, lightweight and inexpensive, as in recent furniture.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and makes the entire door thin, light and inexpensive so that the hanging door can be slid lightly and smoothly. It is an object of the present invention to obtain a locking device.

[0004]

In order to achieve the above object, according to the present invention, there is provided a suspension door suspended so as to be slidable left and right. In a closed position, the suspension door closes a frontage. and in open position, hanging door is moved from the frontage part, so as to be accommodated in the door pocket space formed between the front and rear door pocket wall, wherein the both the front and rear door pocket wall hanging When a locking device with a rod that protrudes and retracts toward the surface of the door is attached and the hanging door is in the closed position,
By the locking operation of at least one of the locking devices ,
The rod is engaged with a part of the hanging door to prevent the movement of the hanging door.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described. As shown in FIG. 1, a roller (3) having a guide groove on its peripheral surface is rotatably supported on the upper end of the hanging door (1) by a plurality of brackets (2) and (2). The roller (3) can move the suspension door (1) between the closed position and the open position by rolling on the rail (4). Although both ends of the rail (4) are not shown,
It is attached to a side panel or a frame member of furniture.

As shown in FIG. 2, a front door pocket wall (6) and a rear door pocket wall forming a door pocket space (5) in which the hanging door (1) is to be housed, before and after the hanging door (1). (7) The hanging door
They are installed in parallel with the smallest possible space between them (1).

[0007] That is, the base end of the double door pockets (6) (7)
The inner end of the frame member (8) is fixedly abutted on the front and rear surfaces of the vertical ridges (9) on the inner surface, and the free ends of both wall bodies (6) and (7) are provided with a gap therebetween to be in an unsupported state. It has become.

The cylinder lock shown in FIG. 3 is located at a position where the free ends of the two wall members (6) and (7) are aligned with each other in the vertical intermediate portion.
(10) is embedded so that the key insertion port (11) comes to the outer surface. At the inner end of the key insertion port (11), a rod (12) is provided which is protruded and retracted by the rotation operation of the inserted key, and this rod (12) is immersed in the wall body except when locking, It does not come into contact with the hanging door (1).

The hanging door (1) is provided with a locking hole (13) into which the rod (12) can be fitted at a position corresponding to the cylinder lock (10) in the completely closed position shown in FIG. . Therefore, when the key is inserted into the cylinder lock (10) and pressed and then turned, the rod (12) fits into the locking hole (13), and the hanging door
The movement of (1) becomes impossible, and the hanging door (1) is fixedly held at that position.

[0010] Instead of fitting the rod (12) into the locking hole (13), the rod (12) is brought into contact with the left end of the suspension door (1), and
The movement of (1) may be prevented, and the locking hole (13) may be omitted.

[0011]

(A) Front door pocket (6) and rear door pocket
(7) Both cylinder locks (8) are provided,
(1) Can be locked freely from inside or outside.

(B) When the hanging door is in the closed position, the rod is engaged with a part of the hanging door by the locking operation, and when unlocked, the rod of the cylinder lock is completely removed from the hanging door. Does not hinder the movement of the door.

(C) Since the mechanism of the locking device is not provided in the suspension door, the entire suspension door can be manufactured thin, light and inexpensively.

Claims (1)

(57) [Claims] 1. A hanging door suspended to be slidable to the left and right, in a closed position, the hanging door closes a frontage portion, and in an open position, the hanging door moves from the frontage portion and moves forward and backward. of so as to be accommodated in the door pocket wall door pocket space formed between the on both the front and rear door pocket wall, fitted with a locking device comprising a rod infested towards the surface of the hanging door, hanging door Is in the closed position, at least
The locking device for a hanging door, wherein the locking operation of any one of the locking devices causes the rod to engage with a part of the hanging door to prevent the movement of the hanging door.
