<p>Door locking handle assembly of a pull-out and side-swinging rotatable locking shaft (5) having a catch plate (4) which is easily mounted on either side of a door, and a handle (8) folded into the casing can be projected outward and operated smoothly regardless of the thickness of the catch plate. A longitudinal groove (60) is provided in an outer surface of the locking shaft (5) (which is connected with the handle (8) through a cross pivot (7)) to open to its rear-end side, and has its front-end portion crossed with a circumferential groove (61) in the outer surface of the shaft (5); and provided in an inner surface of a cylindrical portion (3) (in which the shaft (5) is received) of the casing (2) is a drop-prevention projection (62) which passes through the longitudinal groove (60) to engage with the circumferential groove (61), the projection (62) being so arranged as to be misaligned with the longitudinal groove (60) when the shaft (5) rotates to travel between its locking and its unlocking position.</p> |
