Abstract

PROBLEM TO BE SOLVED: To provide a simple structured latch device which prevents a slide door from moving unexpectedly. SOLUTION: A latch device 7 in reverse L-shape as viewed from the front is formed with an operating lever 8 extending vertically on the outside of a knob body 4 and a latch part 11 which extends horizontally from the upper end of the operating lever 8 and engages and disengages from a hole-shaped engaging part 10 in a vertical frame 1a of a cabinet main body through a through hole 9 drilled at the edge of a vertical side frame 2a of a slide door. A holder part 13 provided projectedly on the operating lever 8 at its middle part in vertical direction is faced toward the inside of the knob body 4 from an inserting hole drilled in one side plate part of the knob body 4. Also, when a platy energizing spring 14 projected from the lower surface of the latch 11 is brought into contact with the upper side plate of the knob body 4 to open and move the slide door, the operating lever 8 is rotated by fingers applied to the holder part 13 about the center of a pin 18 so as to disengage the latch part 11 automatically from the engaging part 10.

According to this structure, when the sliding door is moved in the closing direction, even if the operator puts his / her finger on the handle, no force acts on the operating rod, and the latch is operated by the force of the biasing spring at the closed position. The part is engaged with the engaging part, so that careless opening movement of the sliding door can be prevented. Then, when moving the sliding door in the opening direction, the operator inserts a finger into the handle and moves it away from the vertical frame of furniture. At this time, since the finger facing the handle body is hooked on the handle portion, the operating rod is rotated, the latch portion is rotated against the force of the biasing spring, and the latch portion is disengaged from the engagement portion. This brings about an effect that the operation of moving the sliding door in the opening direction and the operation of releasing the latch can be performed at once. In addition, since the latch device of the present invention has a simple configuration in which the operating rod with the latch portion is disposed near the outside of the handle, it is possible to provide a compact and low-priced device.
