ABSTRACT:
A door locking apparatus has a grip bar mounted on the main handle for operating a door locking bolt. The grip bar is movable forward and rearward. A pair of links are located within the handle, facing the grip bar and forming therewith an isoceles triangle, the base of which is the grip bar. The intermediate portion of each link is pivotally attached to the handle. These links are interconnected to each other at their forward end portions, and are connected at their base end portions to the grip bar, for relative movement therebetween. Consequently, the grip bar can be given a parallel motion even when the same is gripped at any portion.
