Lock for doors and windows

摘要

When closing the door the bolt (32) automatically moves by spring force into a secured closure position. An operating slider (30) set parallel to the rebate (1) can be operated by both keys and press buttons to drive the bolt through a bolt slider or swivel lever (44). The operating slider, biased by spring force in the bolted position is locked by a button-controlled detent member (51, 52) and acts on a tumbler operating lever (11). The swivel lever can sit rotatable on a bolt slider (36).
