Abstract:
1. A door lock comprising: a lock body, a front plate fitted to the lock body and formed with a bolt opening, a dual-action bolt that is movable linearly relative to the front plate between a withdrawn position in the lock body and a protruding locking position in which the bolt projects from the lock body through the bolt opening in the front plate, said bolt being spring-loaded towards said protruding position and comprising a body part, a shaft projecting from the body part in a longitudinal direction relative to the front plate, and two bolt pieces pivotably supported on the shaft of the body part, and a deadbolting means that can be moved to a deadbolting position in which it prevents the dual-action bolt from being moved from the protruding position to the withdrawn position, and wherein each bolt piece comprises a bolt part that projects through the bolt opening when the bolt is in the protruding position, a first projection extending away from the bolt part in a longitudinal direction of the shaft and having a first counter surface arranged to directly cooperate with an inner surface of the front plate when the bolt is in the protruding position, and a second projection which, in relation to the support of the bolt piece on the shaft, is arranged on an opposite side of the bolt part in an opposite longitudinal direction of the shaft as compared to the first projection and having a second counter surface arranged to cooperate with the inner surface of the front plate, and wherein a portion of the first projection and a portion of the second projection share a same plane.
