Abstract
A door latching assembly readily adaptable to a standard cylindrical lock provision includes a unitary bolt/handle member substantially shielded by a fixed cover with at least a portion of the handle confined within a retainer member which defines alternate positions of the bolt and establishes a slot with the cover to provide a guide for the handle. Mating lock receiving openings in the handle, retainer member and cover provide for the application of either one or two lock devices to immobilize the bolt in a door locking position. By the symmetrical formation or assembly of certain components and the selective positioning of the lock receiving openings, the mechanism of this invention may be alternately utilized in either a left-hand or right-hand door lock installation without any structural modification of the components.
