Drive bolt lock for two-wing door, has contact element displaceably mounted at base part of bolt slide between two end positions, and spring applying force to contact element in direction of push bolt

摘要

The lock has a bolt slide including a base part (2), which is driven by a drive of an opened counter box (1) for opening an inactive leaf of a door in a direction of a push bolt. The base part includes a contact element (3) at an end (2e) facing towards the push bolt. The bolt slide applies a force to the push bolt, and pushes away the push bolt over the inactive leaf by the contact element during opening the door. The contact element is displaceably mounted at the base part between two end positions. A spring (4) applies the force to the contact element in a direction of the push bolt.
