ABSTRACT:
A lock mechanism is provided with a housing having a closable flap pivoted thereon. The flap carries a key releasable lock cylinder equipped with locking elements and a locking bolt slidable under the action of a return spring. The locking bolt comprises a shoulder cooperating with a stud mounted on a cam plate which pivots to bring the bolt into the open position against the action of the return spring, whereby the bolt is disengaged from a fixed abutment. The cylinder and cam plate can occupy a locking position (v) in which the locking elements are resiliently urged into a locked position within locking grooves formed in the closable flap so that the stud locks the bolt. When the cylinder and cam plate are moved to a second position (F) angularly displaced from the locking position (v) the stud frees the locking bolt so that the bolt can move for the purpose of locking or unlocking the flap whether or not the key is present in the lock mechanism.
