Abstract:

A four point locking system for a storage cabinet having a pair of outwardly pivotable doors which provide access to the cabinet interior. The locking system includes a lock bar vertically disposed in each door and adapted to be moved downwardly into the bottom lintel of the cabinet. A plunger bracket is pivotably mounted within the top of the cabinet and includes plunger flanges which move down through the top lintel of the cabinet into each door to lock the top portion of the cabinet doors while simultaneously moving the lock bars downwardly to lock the bottom portion of the cabinet doors. The pivotable movement of the plunger bracket is controlled by a lock push bar which is directly connected to a lock push button extending through the front of the cabinet. An extension spring is utilized to bias the push bar and plunger bracket towards the unlocked position while compression springs attached to the lock bars bias the bars upwardly to their unlocked position. Thus, the doors are locked at both an upper and lower position.
