Abstract
A lock has a bolt and a key-operated barrel at right angles, and with their axes coplanar. A pinion has teeth which engage teeth on the bolt and teeth on an extension of the barrel. The pinion, bolt and barrel are in a longitudinally split housing, held together by screws, the pinion having a slot to receive one of the screws. The barrel lock moves a latch plate transverse to its axes, so as to extend into a slot in the housing to prevent movement of the barrel.
Claims25
A right angle door lock comprising:
- (a) a housing,
- (b) a key-operated barrel assembly axially slidable in said housing;
- (c) an axially slidable bolt in said housing;
- (d) means mounting said barrel assembly and said bolt with their axes intersecting and coplanar, and
- (e) means engaging said bolt and said barrel assembly for causing conjoint movement thereof, comprising a pinion coplanar with said barrel assembly and said bolt, said barrel assembly and said bolt comprising racks, said racks being substantially coplanar;
- (f) whereby said lock may be of small thickness transverse to the plane of said axes.
