Lock

Abstract

The present disclosure relates to a lock for installation in a door leaf defining a first plane. The lock comprises a housing; and a bolt moveable relative to the housing between a retracted position, and an extended position in which a distal portion of the bolt protrudes from an opening in the housing. The bolt is resiliently biased into the extended position. The distal portion of the bolt comprises at least one shoulder sloped in a plane parallel to the first plane, such that the bolt is moveable into the retracted position in response to a force applied to the shoulder. The lock further comprises a first lock mechanism operable to move the bolt between the retracted and extended positions; and a second lock mechanism operable to move the bolt between the retracted and extended positions. At least one of the first and second lock mechanisms is operable independently of the other of the first and second lock mechanisms. The bolt is moveable into the retracted position independently of each of the first and second lock mechanisms.

Dependencies are inferred from the claim text.
