Abstract
A compact push-pull right-angle lock especially suited for use on patio doors and on windows has a cylindrical bolt with rack teeth on its central section, a barrel lock assembly, and a rotatable disk all contained in a horizontally split case. The bolt can be extended in either direction by the right angled linear motion of the barrel lock assembly. Linear motion of the barrel lock assembly is transferred to linear motion of the bolt through a disk that is free to rotate some fifty degrees about a shaft. The barrel lock assembly is loosely linked to a crank pin set perpendicularly to the plane of the disk and the bolt rack is meshed with an arcuate section of a pinion gear on the disk located some ninety degrees from the crank pin. The bolt can be locked in either extended position by means of a cam lug which cna be moved from the barrel lock assembly housing into locking recesses in the case by rotational movement of the keyed barrel lock. Means are also provided for replacement of the barrel lock when necessary.
