To change the open / close plate B from the open state to the closed state, it is only necessary to push and close the open / close plate B by hand. At this time, the upper end of the hook 16 of the hook mechanism 14 comes into contact with the locking member 20 as shown in FIG.
Only the hook 16 retreats into the hook casing 15 once against the urging force of the coil spring 18 along the inclined surface 16a provided in the hook casing 15. Then, the opening and closing plate B is closed and the inclined surface 16 is closed.
When "a" has passed the locking member 20, the hook 16 projects again from the hook casing 15 and is locked by the locking member 20, so that the closed state of the opening / closing plate B is locked. At this time, since the space between the hook 16 and the connector 17 is configured to be slidable in the vertical direction by the slot 16 b and the retaining pin 19, only the hook 16 is retracted into the hook casing 15. Therefore, the connecting rod 11 does not retreat downward, and the latch mechanism 1 does not operate at all.

Therefore, in the above-described handle device for furniture or the like, the handle 5 which is supported by the rotation operation shaft 4 of the latch mechanism 1 and rotates the rotation operation shaft 4 from the outer wall side of the opening and closing plate B,
Since the handle portion 6, the spacer 7, and the handle shaft 8 are divided so as to be freely engageable, and the handle portion 6 and the handle shaft 8 are also configured to be freely engageable, FIG. When the handle 5 is formed by the handle portion 6 and the handle shaft 8 excluding the spacer 7 as shown in FIG. 4, the front and rear length of the handle 5 corresponding to the thin opening / closing plate B is reduced, and the handle 5 is opened and closed. The appearance can be improved without much protruding to the outer wall side of the plate B. As shown in FIG. 6B, a plurality of (two in the figure) spacers 7 having the same shape are prepared, and a plurality of (two) spacers 7 are interposed between the spacer 7 and the handle shaft 8. If this is done, the front and rear length of the handle 5 becomes longer corresponding to the thicker opening / closing plate B, so that the rear end surface of the handle portion 6 does not contact the outer wall surface of the opening / closing plate B and hinders rotation of the handle 5. Never come. As described above, in the above-described handle device for furniture or the like, the handle 5 having the above-described configuration allows
Versatility not affected by the thickness of the opening / closing plate B can be obtained.

In the above-described embodiment, the slider 3 of the latch mechanism 1 caused by the opening and closing of the opening and closing plate B is connected by the connecting rod 11 as a handle device for furniture or the like corresponding to the thickness of the opening and closing plate B. It is configured to be locked to the locking member 20 on the main body A side such as furniture via the hook mechanism 14, but can be locked to the locking member 20 only by the latch mechanism 1 without using the hook mechanism 14.
