When furniture shakes or falls over,
In the conventional locking device, a force greater than the locking force of the locking device acts on one or both doors due to the swinging of the door, whereby the locking device comes off and the door opens naturally, and the door is damaged, The stored articles may pop out and damage the articles. In addition, it is conceivable to use a key attached to the door to prevent the door from opening unnecessarily in response to such a large shaking, etc. Therefore, there is a problem that it takes more trouble than necessary and is troublesome. The present invention solves the problems of the above-described conventional door opening prevention bracket, and does not open the door due to the force in the direction of opening the door directly from the outside of the door even manually due to an earthquake or large vibration. As long as the doors attached to furniture such as cupboards and closets do not open naturally, the doors can be opened to prevent the furniture from falling over and the damage caused by the stored items jumping out. The purpose is to provide metal fittings.

In this case, the locking claw 20 is locked to the link 40 by the pin 33, and the two latch bolt pieces 11.12 are combined by the pin 32 to be integrated and stored in the case 1. At this time, link 40
A lock lever 30 is supported at the rear end of the housing.
Assemble with 7 interposed. In this manner, the locking tool bodies A and B are assembled, and the doors D1. It is attached to the back side of D2 with screws or the like so as to face each other. In this case, the locking claw 20 of the locking body A faces the locking claw 3 of the locking body B, and the locking claw 20 of the locking body B locks the locking body A. The two doors D1. When D2 is completely closed as shown in the figure, the locking claw 20 and the locking claw 3 are not locked to each other, but when the door starts to open, they are locked to each other. The interval is determined.

B, like the conventional latch bolt, the latch bolt 10 protrudes by the action of the spring 27, but when the door is closed, the latch bolts 10 come into contact with the other door, and the latch bolt temporarily stops from the protruding state against the spring 27. It is pushed in, the door is closed, and the state as shown in FIG. 1 is obtained. And when opening the door, the depression H of the handle H
When the finger is inserted into the inside of the lock lever 30a and pulled forward, the operation piece of the lock lever 30 is naturally pulled by the finger, and the lock lever 30 is rocked in the direction of the arrow. The projection 22 fitted and locked in the recess 14 with the piece 20 as a fulcrum using the pin 32 as a fulcrum is guided in an arc shape and is made to move in an arc to be swung in the upright direction. 20 and the locking claw 3 are completely separated from each other and do not lock each other, so that the door can be freely opened and closed.
