Locking device with a catch for preventing rotation of a latch bolt

Abstract

The present invention relates to a locking device comprising an elongated face plate (30) for mounting on a door, the face plate comprising an opening (31) for a latch bolt, a latch bolt (10) having a bolt body (11) with a first end (11A) and a second end (11B), the bolt body (11) comprising a first surface (12) and a second surface (13) that are on opposite sides of the first end (11A), wherein the latch bolt (10) is configured to move from an extended position with the first end (11A) protruding from the opening (31) in the face plate (30) to a retracted position, and wherein the bolt body (11) is further configured to rotate around an axis that is parallel to the face plate (30) in response to a force applied to the first surface (12), and wherein further the second surface (13) is curved for sliding along an edge (33) of the opening (31) in the face plate (30) during rotation of the bolt body (11), and the locking device (1) further comprising a first blocking surface (14) on the second end (11B) of the latch bolt (10), and a first catch (22) movable to a blocking position in which the first catch (22) engages the first blocking surface (14) for preventing the rotation of the bolt body (11).
