Also has the advantage of being usable.

  By attaching a movable pin for locking with a spring to a locking / unlocking device that can simultaneously unlock and unlock multiple drawers such as cabinets and furniture by operating cylinder locks, levers, etc., locked with some drawers pulled out Even if the drawer that was pulled out is pushed in, the locking projection and unlocking device that can be easily closed while lifting the movable pin for locking and engaged with the latch with a simple structure with few parts is realized. .

  FIG. 1 is a side view of an embodiment of the apparatus of the present invention, and shows a state in which all drawers are locked by engaging a movable pin for locking and a slide rail latch that are housed in a drawer and attached to an elevating rod. It is a thing.

  FIG. 2 is a side view of the embodiment of the device of the present invention, in which the movable pin for locking attached to the lifting / lowering rod is detached from the latch of the drawer slide rail and all the drawers are unlocked and can be pulled out. It is the one shown.

  FIG. 3 is a side view of an embodiment of the apparatus of the present invention showing that the drawer is pushed in while lifting the movable pin for locking the latch projection of the drawer slide rail attached to the lifting / lowering rod while the drawer is being stored. It is a thing.

  FIG. 4 is a three-dimensional view of the embodiment of the device of the present invention, which clearly shows the small number of parts and the ease of assembly of the locking and unlocking device of the present invention.

  FIG. 5 is a three-dimensional view of an embodiment of the device of the present invention showing a state in which a slide rail with a locking latch is attached to a drawer.

  FIG. 6 is a side view of an embodiment of the device according to the present invention, which is an embodiment of a locking / unlocking device in which a latch is provided on a lift and a movable pin for locking with a spring property that engages with the latch is attached to a drawer side. An embodiment in which the operation of the device of the present invention is enabled by a slide rail is shown.

  The locking / unlocking device of the present invention can be manufactured at low cost because the manufacturing cost of the locking / unlocking device can be greatly reduced due to the small number of parts and the ease of assembly. It can also be applied to applications such as cabinets or furniture with multi-stage drawers on the market.
