5 is stably moved in the guide groove 72, and the latch member 63 descends against the biasing force of the spring 92. As a result, the latch 7 held by the latch receiver 3 is released from the latch receiver 3, and the door D can be opened with good operability. Further, the handle 5 is provided with the latch 7 via two bolts 90, 90 screwed to the two leg portions 24, 24.
Since it is disengaged from the latch receiver 3, it is possible to improve the operational stability of the latching device 99, and various handles such as biaxial and triaxial can be used, and the flexibility of the design of the attachable handle can be increased.

It is locked to the bridge 3. Therefore, the careless opening of the door D can be reliably prevented, and the stored items can be prevented from being scattered outside even in the event of an earthquake or the like.

The latch receiver 3 may be attached to the lower surface of the horizontal top plate 20 as in the present embodiment, or may be attached to a vertical surface such as a side plate or an upper surface such as a bottom plate. At this time, the protruding direction of the latch 7 is the lock body 2. By changing the direction of, change to side, downward, etc.

作でき、操作性を向上しうる。As described above, in the door latch lock device of the present invention, the handle is such that the handle can be moved away from the outer surface of the door, and the door is detached from the latch receiver by the move of the handle. And a lock body having a latch for opening, and the latch is locked to a latch receiver when the door is closed. Therefore, when the door is closed, the latch is locked by the latch receiver, so even if furniture or the like falls over in the event of an earthquake, the door can be reliably prevented from opening, and the stored items will not be scattered. In addition to preventing breakage, the latch is separated from the latch receiver by the separation movement of the handle portion of the handle, so only one operation of pulling the handle is required to open the door. Etc. can be easily operated and the operability can be improved.

Since the rod is interposed between the latch and the handle when it is provided, the handle can be provided at any position on the door, and the rod is arranged apart from the inner surface of the door. Therefore, this rod is not exposed to the outside, it is possible to prevent the deterioration of the appearance,
Compared to the one built in the door, the door does not need to be made thicker than necessary, maintenance is easy, and there is no need to provide a hole for a rod to pass through at the edge of the door. Can be realized.
