Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction of a latch device for a drawer in a cabinet.

A door plate is installed in the opening at the front of the cabinet body, and this door plate can be opened upward and rotated to store the cabinet in a substantially horizontal position. Some have a shaped drawer that can be moved back and forth.

In order to move the drawer of this type of cabinet back and forth, you must put your hand on the front edge of the shelf part of the drawer, so the latch device that connects and disconnects the drawer from the cabinet body is also located near the front edge of the shelf part. It is necessary to provide
For this purpose, it is necessary to make the structure of this latch device compact.

The object of the present invention is to provide a latch device with such a compact structure.

Next, an embodiment of the present invention will be described. In the figure, reference numeral 1 indicates a main body of a file storage cabinet made of a thin metal plate. At the front opening of the main body 1, there are vertically multi-tiered structures between the left and right side plates 2, 2 of the main body. Door plates 3... are arranged, and each door plate 3 is mounted so as to be able to rotate upwardly around its left and right upper ends, and is configured so that the door plate 3 can be stored in the main body 1 in a horizontal state. .

4 is a left and right side plate 2 for each door plate 3 arrangement location,
A front-open type shelf-shaped drawer is provided between the drawer 4 and the drawer 4 so as to be movable back and forth via a pair of left and right suspension devices 5.The drawer 4 has upwardly protruding side plates at both left and right ends of the left and right longitudinal shelf parts 6. While providing 7,7,
Separators 8 are removably provided between the upper surface of the shelf section 6 and the rear panel section in parallel with the side panels 7, 7.

the drawer side rail 9 of the suspension device 5;
9 is fixed to the outer surface of the left and right side plates 7, 7 of the drawer 4,
The main body side rails 10, 10 are the main body 1 left and right side plates 2, 2.
It is fixed to the inner surface, and the drawer side rail 9 is suspended from the main body side rail 10 via an intermediate rail 11, rollers 12, and balls 13 so as to be movable back and forth. Reference numeral 14 denotes a main body side rail 1 that prevents the intermediate rail 11 from moving forward when the drawer 4 is pulled out to the frontmost position.
This is the stopper part at 0.

Reference numeral 15 denotes a latch device which is provided longitudinally in the left-right direction at the front end of the lower surface of the shelf board portion 6 of each drawer 4 and can be engaged with and detached from the main body side rail 10, and is connected to the operating portion 16, the connecting rod 17, and the locking piece 18. Become. A case 16' of the operating section 16 is fixed to the lower surface of the left and right longitudinal reinforcing section 6' formed by bending the front end of the shelf section 6 into an upward convex strip, and is fitted into the case 16' so as to be slidable back and forth. The rear part of the inserted pushbutton 19 is formed into a pair of upper and lower inclined guide parts 20, 20, while both ends are connected to the case 1.
The middle part of the spring stopper 21 that is inserted and locked in the upper and lower inclined guide parts 20, 20 is placed between the upper and lower inclined guide parts 20, 20, and the compression spring 22 is inserted between the push button 19 and the spring stopper 21. Case 1
6' Press and bias toward the front side. Furthermore, a connecting rod 17 that is slidable left and right at right angles to the back and forth movement of the push button 19 is fitted into the rear part of the case 16', and an abutment 23 that is fitted and fixed to the connecting rod 17 is fitted to the upper and lower inclined guide portions 20, 20. Slidingly abutting and connecting rod 1
A spring 24 biases the locking piece 18 connected to the main body side rail 10 to lock it to the stopper 14 of the main body side rail 10. Reference numeral 25 denotes a guide body that supports the locking piece 18 that protrudes from and retracts from the side end surface of the shelf plate portion 6 so as to be slidable on the lower surface of the reinforcing portion 6'.

With this configuration, in order to pull out the drawer 4 as shown in the second row of FIG. Then, hold the top surface of the front edge of the shelf-like drawer 4 stored in parallel below the horizontal door plate 3 with your hand, and at the same time press the push button 19 with your thumb or the like as shown in the arrow in FIG. When pushed in the direction A, the inclined guide part 20 at the rear of the push button 19 also retreats, and the abutment 23 that comes into contact with it is forcibly moved in the direction of the arrow B, and the connecting rod fixed to the abutment 23 moves backward. 17 moves in the direction of arrow B, and the tip of the locking piece 18 attached thereto sinks inward from the side end of the drawer from the back surface of the stopper part 14 of the main body side rail 10 (see the two-dot chain line in FIG. 3). As a result, the engagement between the drawer 4 and the cabinet body 1 is released, and the drawer 4 can be freely moved back and forth.
Note that when the drawer 4 is pushed into the cabinet body 1, the inclined surface at the tip of the locking piece 18 is pressed against the stopper part 14, and the connecting rod 17 is pressed against the spring 2.
4, it can move laterally in the direction of arrow B in FIG. Furthermore, the upper and lower inclined guide portions 2 behind the push button 19
0 is formed in a V-shape across the left and right sides (both sides of the forward and backward movement of the connecting rod 17) in the case 16' as in the embodiment shown in FIG. If the left and right movable dimensions are made to be different sizes on the left and right, this push button 19
By inserting the locking piece 18 into the case 16' by changing the left and right directions, the amount of lateral movement of the locking piece 18 can be selected.

In this way, the present invention provides a door plate in the front opening of the main body of the cabinet so that it can be opened and closed upwards, and a separate front-opening shelf-like drawer is installed at each location of the door plate on both the left and right sides of the main body. A suspension is provided between the plates so as to be movable back and forth, and an operation part case equipped with a push button that protrudes forward from the front edge and is biased is fixed to the lower surface of the front edge of the shelf part of the drawer, and the shelf part A locking piece is provided on the lower surface from the side end surface of the suspension to move laterally in and out of the stopper part of one of the rails on the main body side of the suspension, and a connecting rod is connected to the locking piece. a direction in which the locking piece is unlocked from the stopper portion in response to the backward movement of the push button, and the abutment of the connecting rod, which is fitted and inserted so as to be able to move laterally, and the inclined guide portion formed at the rear of the push button; The operating part, connecting rod, and locking piece of the latch device can be arranged linearly on the lower surface of the front edge of the shelf part of the drawer, and are connected to the inclined guide part at the rear of the push button. The abutment of the rod can reliably change the backward movement of the push button into the lateral movement of the locking piece, and has the effect of making the structure extremely compact.
