  • Lock, particularly mortise lock
    Patent number: 5301525
    Abstract: A lock, particularly a mortise lock, with bolt (9) and preferably catch (43) and a step-up lever (27) which acts on the bolt (9) and is equipped with a closure engagement opening (30) and is pivoted below the axis of rotation of the closure bit, for the closing of the bolt (9) in forward and backward direction while obtaining a lengthening of the closing stroke; in order to optimize the design, it is proposed that the path of movement of the closing engagement opening (30) extend approximately over a quarter-circle (V) of the cylindrical head (7) of a profiled-cylinder insertion opening (4).
