Lock Mechanism with a Key Removal Interlock and an Interlock of Key Removal from a Lock Mechanism

Abstract

It is the object of this invention to provide a lock mechanism with a key removal interlock, and an interlock of key removal from a lock mechanism, for locks with a cylinder, enabling removal of the key from the lock in only one angular position. A lock mechanism with a key removal interlock, comprising a cylinder 1 with two concentric sleeves, an inner sleeve 2 and an outer sleeve 3, with locking components 5 radially arranged angularly in rows 4 along the axis of the cylinder 1 and positioned in channels 6 formed in the inner sleeve 2 and the outer sleeve 3, unlocked with a cylindrical key with an internal guiding bore and positioned on the key outer surface decoding elements, is characterized in that at least two radially arranged angularly rows 4 of locking components 5 are positioned in the inner sleeve 2 and the outer sleeve 3 with different angular spacing. An interlock of key removal from a lock mechanism, comprising a cylinder 1 with two concentric sleeves, an inner one 2 and an outer one 3, with locking components 5 radially arranged angularly in rows 4 along the axis of the cylinder 2 and positioned in channels 6 formed in the inner sleeve 2 and the outer sleeve 3, unlocked with a key with a cylindrical shank with an internal guiding bore and positioned on the outer key surface decoding elements, is characterized in that at least in one row 4 of locking components 5 the number of channels 6 is different than in the remaining rows 4 of locking components 5.
