Patent

CA 2152020

A window lock includes a lock base fixed to a first window sash and a lock catch fixed to a second window sash. A lock casing is mounted for linear reciprocation on the lock base. A pivotal locking member is mounted on the lock base so as to selectively engage the lock catch. A linkage mechanism interconnects the lock casing with the pivotal locking member and transforms the linear reciprocation of the lock casing into pivotal reciprocal movements of the locking member. A safety mechanism is provided to selectively prevent accidental or unauthorized linear reciprocation of the lock casing. The lock casing substantially surrounds the lock base, the linkage mechanism, and the safety mechanism, thereby providing the window lock with an aesthetically pleasing appearance suitable for modern decors.
