2. Description of the Related Art A conventional latch device in this type of lateral open type cabinet is, for example, an actual open flat 62-17636.
As can be seen in Japanese Patent No. 5, a latch is attached to one side of the front end of the drawer so that it can move left and right, and a latch provided in the middle of the front of the bottom plate is slid to move the latch horizontally in the release direction. It is designed to let you.

However, in the above-described conventional latch device, since the latch function (locking function) works only on one side end of the drawer and the other side can be freely drawn out, a wide cabinet can be used. The strain may occur due to the pop-out operation of the drawer, the excessive pull-out operation, or the like, and the latch may be disengaged or the latch device may be damaged.

Further, in the conventional latch device, the operating direction of the knob is the same as the left and right direction as the moving direction of the latch, which is completely different from the pulling-out direction of the drawer. There is also a drawback that it requires a latch release operation and a pull-out operation).

According to a second aspect of the present invention, a puller is pivotally supported at an intermediate position between the left and right latches so as to be rotatable frontward about a horizontal pivot shaft, and When the vertical rising parts formed on both left and right ends are brought into contact with the rear surface of the operating rod part of the latch that can rotate about the vertical axis, when pulling out the drawer, rotate the puller in the pulling direction. With this, the engagement of the left and right latches is released, and then the turning operation of the pulling hand naturally shifts to the pulling operation, so that the drawer can be pulled out.

If the front cover attached to the front end of the bottom plate of the drawer is equipped with the latch and the puller as in the third aspect of the invention, the processing for pivotally supporting the latch and the puller on the drawer body is unnecessary. Therefore, the drawer main body is easily manufactured from steel, and the front end surface of the bottom plate is formed by a separate front cover made of, for example, synthetic resin (the resin makes it easy to form the latch and pivot of the puller). It is well dressed and has a latch mechanism built into it.
