Description

  The present invention relates to a drawer device mounted on a fixture such as a desk or cabinet used in a work space such as an office.

  In many cases, this type of drawer device is provided with a locking device in order to prevent the stored items from being stolen.

  In the locking device, there are a plurality of drawers arranged adjacent to each other in the upper and lower sides and a drawer that can be locked together, and a drawer that can lock each drawer individually. These are selected and applied according to the user's request, and are particularly suitable for use by assigning the drawer to an individual when a lock device is provided for each drawer individually.

  As a locking device that can lock the drawer individually, the dead bolt that interlocks with the locking operation of the cylinder lock is protruded from the left or right side of the drawer toward the side, and the engagement is provided on the fixture. Many are locked by being inserted into the holes (see Patent Documents 1 to 3).

  According to this structure, the locking device can be configured easily and inexpensively. However, since one side of the drawer is fixed, if the drawer body is wide left and right or the drawer itself has low rigidity, locking on the side of the drawer on the non-locking side There is a problem that the forward / backward moving part becomes large, rattling is likely to occur, and it cannot be stably and reliably locked.

On the other hand, in conjunction with the locking operation of the cylinder lock, a pair of left and right dead bolts protrude outward from the left and right side surfaces of the drawer, and each fits into an engagement hole provided in the fixture. There is something which is made to do (refer patent document 4).
According to this structure, since both sides of the drawer can be fixed at the time of locking, as described above, even if the drawer is wide left and right or low in rigidity, it can be locked stably and reliably. Can do.
