摘要

Operating handle (5) for a lock fixed in or on a door leaf comprises a nut rotatably mounted about an axis, and at least one latch which can be displaced against the action of a spring. The handle displaces the latch by rotating a square (2) engaging in the nut. The lock-side end (5b) of a neck (5a) fixed to the handle acts on a rotating disk (4) fixed to the door (3) by a housing (6). The disk is rotated by displacement of the handle and produces the rotational movement of the square. Preferred Features: The neck of the handle is a flat plate, a double rod, or a round part.
