ABSTRACT:
A lock for a door has a housing with an opening, a latch bolt and a further latch bolt both mounted to the housing for parallel displacement relative to the housing. A latch follower formed as part of a latch is connected to the latch bolt as is a changer, with the parallel displacement occurring due to the action of one of the latch follower via the latch and the changer via a key. A lock cylinder is situated in the housing opening. Two drive rods and associated control plates are provided along and a changer lever hinged to one of the control plates and connected to the lock cylinder. The lock cylinder can drive the changer via the changer lever and its hinged control plate. One side of the lock has, therefore, two drive rods.
