Door lock

A door lock comprising a lock body (14) fitted with a front plate (13);

• the lock body has a dual-action bolt (15) that can be moved with reciprocal linear motion between a withdrawn position and a protruding locking position out from the lock body through a bolt opening (16) in the front plate (13), said bolt being spring-loaded towards said protruding position, said dual-action bolt (15) comprising a body part (22) fitted with a shaft (29) longitudinal to the front plate, as well as two bolt pieces (23) pivotably supported on the body part around its shaft, said bolt pieces comprising a projection (24) facing away from the body part in the longitudinal direction of the shaft (29), said projection having a counter surface (25) arranged to cooperate with the inner surface (30) of the front plate;
• said door lock further comprising deadbolting means (17) that can be moved to a deadbolting position in which they prevent the dual-action bolt from being moved from the protruding position to the withdrawn position in the lock body (14),
• characterised in that both bolt pieces (23) comprise a second projection (26) which, in relation to the support of the bolt piece on the shaft, is arranged on the opposite side in the direction of the shaft (29) compared to said away-facing projection (24), said second projection having a second counter surface (31) that is arranged to cooperate with the inner surface (30) of the front plate.
