ABSTRACT:
There is disclosed an improved handle assembly which relates to a pop-out T-handle lock assembly of the type having a cylinder front handle which mates with a cylinder housing, which in turn houses a cylinder lock and related extension rod therein.
The improved handle assembly is formed by providing an inner handle secured to the cylinder housing at the front end thereof, the inner handle having a pair of opposed attachment flanges extending outwardly therefrom. Each of the attachment flanges includes a screw receiving channel formed along the inner surface thereof, and the cylinder front handle is provided with a pair of opposed threaded apertures in spaced apart relation traversing side walls thereof and positioned to be in registry with the screw channels formed in the inner handle when the cylinder front handle is mounted to the inner handle. A pair of threaded screws are provided for removably engaging the cylinder front handle to the inner handle, the threaded screws being received through the threaded apertures and through the screw receiving channels formed in the inner handle. The assembly permits the easy removal of the cylinder front handle to gain access to the inner handle and the related cylinder housing and associated lock and extension rod.
