Abstract:
A lock for door or window, said lock comprising:a lock housing including a selvage having an opening;a latch bolt, mounted for slidable movement in said lock housing, which in a normal position is held projecting out of said opening by a force exerted by a bolt spring and can be retracted into an opening position against the bolt spring force,a hub capable of turning, which is held in an initial position by a force exerted by a hub spring, and which is capable of turning against the hub spring force in an opening direction by means of an operator,a mechanical connection between the hub and the latch bolt such that by turning the hub in the opening direction, the latch bolt is retracted into the opening position against the bolt spring force,and a translating part which is capable of moving essentially at a right angle to the direction of motion of the latch bolt from an unlocked position to a locked position and is connected operationally with the hub, said translating part including a front edge facing toward said selvage and a rear edge facing away from said selvage, said front edge including an active part interacting with the latch bolt,wherein the rear edge of said translating part abuts said mechanical connection to define the normal position of said latch bolt when said translating part is in said unlocked position, and said translating part can be moved from said unlocked position into said locked position by turning the hub from its initial position in a direction of rotation opposite the opening direction and with this motion of the translating part the active part of the translating part forcibly pushes the latch bolt into an extended position in which the latch bolt projects out of the lock further than in the normal position.
