Abstract
A standard 'diamond back' lock configuration, as used in drawer locks, includes a dead bolt with an angled slot. The angled slot provides an improved camming action which produces the same amount of linear dead bolt motion with 90.degree. of lock plug rotation as a conventional, non-angled slot with 180.degree. of rotation. In addition, since only 90.degree. of rotation is necessary to fully extend or retract the dead bolt, a user can ascertain whether the lock is engaged or not by the relative orientation of the keyway entry. Also, with 90.degree. of lock plug rotation, key retention at the unlocked position can be provided as an added feature of the lock.
