FIELD: construction.SUBSTANCE: lock for nonworking door leaf of double door corresponding to the invention includes lock housing (23), catch (17) and control wedge (18). This control wedge is designed with possibility of liner movement to the position, in which it is protruded from the lock, and to the position, in which it is retruded inside the lock. In addition the lock contains lever (20), drive member (21) and spring system (27). By its first end lever (20) is attached with possibility of turn to control wedge (18), this is specified by position (25), and by its second edge it is attached with possibility of turn to drive member (21), this is specified by position (24). Drive member (21) is also attached with possibility of turn to lock housing (23), this is specified by position (22), and this drive member contains control cam (26) connected to catch (17).EFFECT: lever and drive element are designed with possibility of transmission of spring system force to control wedge so that the force parallel to liner movement of control wedge is the highest, when control wedge is in protruded position, and the lowest, when it is retruded inside the lock.10 cl, 5 dwg |
