ABSTRACT:
A door-handle assembly comprising a rotatable spindle, a core retainer, a knob and an interchangeable lock core. The spindle and the retainer are so designed that the retainer is selectably oriented either upwardly or downwardly with respect to the spindle. The knob and therefore the lock core are then inverted in view of the invertable retainer so that a key for manipulating the lock core is used with its key cuts similarly either upwardly or downwardly oriented during use.
