Abstract
The present invention relates to a locking device for a multi-stage drawer of a new structure which is simple in structure and reliable in operation and which is vertically installed inside a side wall (3) adjacent to an opening (2) of a case (1) The stopper 14 is mounted on the outer side of the side wall 8 of the drawer 6 and the stopper 14 is mounted on the stopper 14, And a stepped portion 22 which gradually slides down or rises in the vicinity of the outer cover 7 of the drawer 6 and a guide rail And a locking piece 28 protruding from an upper portion or a lower portion of a stepped portion 22 of the guide rail 20 of the side wall 8 of the drawer 6.
Description
The present invention relates to a locking apparatus for a multi-stage drawer, and more particularly, to a locking apparatus for a multi-stage drawer with a new structure which is simple in construction and easy to manufacture and reliable in operation.
When two or more drawers are pulled out simultaneously from a file box or other multi-stage drawer, the center of gravity of the drawer may be pulled forward and the drawer may fall down, It is desired that the drawer be provided with a locking device which, when one drawer is pulled out, causes the other drawers to remain closed without being withdrawn.
As a conventional locking device for a multi-stage drawer, there is known a domestic utility model registration No. 20-0437406, which is characterized in that a drawer, which is stacked in a multi-stage at the rear of a drawer, And a stopper of a predetermined type is mounted on a rear end of each drawer. When a user takes out one of the drawers, the rotating bar is elastically rotated and the rotating bar is separated from the stopper of the drawer engaged with the rotating bar The stoppers mounted at the rear of the other drawers are instantly released from engagement with the rotary bar. However, due to the resilient restoring force of the spring, the rotary bar resiliently returns to the stoppers of these other drawers, The withdrawal is stopped.
However, in the conventional multi-stage drawer locker, when the drawer is pulled out, when the drawer is retracted and the other one of the drawers is pulled out, There was a disadvantage that a large amount of operation noise was generated at the time of withdrawing the drawer in the office requiring the quietness. In addition, in order to move the rotary bar and the fixing bar away from the stopper engaged with the rotary bar and return the same to the original position by the elastic force of the spring and precisely perform the locking action with respect to the other drawers, In addition, the mounting positions of the stoppers in the vertical direction of the respective stacked drawers must be precisely matched. Therefore, there is a problem in that the manufacture is troublesome. In the case where precise processing or precise positioning is not performed, There has been a problem that there is a high possibility of malfunction.
The present invention has been made in view of the problem of the locking device for a multi-stage drawer as described above. The present invention is a new structure in which a detailed structure is simple and easy to manufacture, operation reliability is high, In order to provide a locking device for a multi-stage drawer.
