Abstract: The invention relates to an installing mechanism and its deinstalling tool for a control turning handle (150) of a lock on an actuating rod (17) comprising two assemblies (E1, E2) that interact via a bayonet-type assembly by an axial engagement in the direction of the leaf then a rotation in a circular arc branch, in a second direction opposite the first direction around the axis of the rod, of the second assembly (E2) on the first set (E1), characterized in that each circular arc branch comprises an engagement limit stop upon which an associated stub rests, and a retractable stop for rotationally blocking the associated stub in the circular arc branch. The invention is particularly for use in a hygienic handle.

Abstract: The invention relates to a hygienic, turning control element which is used to actuate a mechanism, such as a door opener. More specifically, the invention relates to a hygienic turning handle (12) which is intended to be fitted to a door and which is used to control the actuation of a mechanism, such as a lock. The invention is of the type that consists of a hub (18), a main body (20) and a left-hand form actuation segment (26) comprising an essentially C-shaped inner concave surface which extends from the plane of the door. The invention is characterized in that, in the handle (12) rest position, the concavity of the actuation segment (26) is essentially oriented upwards and can receive part of the arm, the wrist or the back of the hand of a user.
