An actuation handle assembly for a door or window, comprising:
- an installation body arranged to be installed on a door or a window;
- a handle having a handle neck, the handle being rotatably connected with the installation body, wherein the handle has a driver that is arranged to form an operative connection with an actuation element in the door or window;
- first and second detent elements respectively arranged to engage with each other in at least one functional position of the handle in a force-locking and/or positive-locking manner, wherein the first detent element is a detent recess formed on a detent ring which can be moved in an axial direction (A) and is mounted on the handle neck in a non-rotatable manner, and wherein the second detent element is a detent projection provided on a counter detent ring that is mounted on the installation body in a non-twisting manner, wherein the detent projection corresponds to the detent recess;
- and
- a compression spring positioned in the handle neck and arranged to push the detent ring against the counter detent ring in the axial direction (A);
- wherein the handle neck is provided with a guide sleeve, which receives the driver in a non-rotatable manner in a central position with respect to a rotary axis (D) of the handle and which is provided with guide elements along its inner circumference;
- wherein the detent ring has an identically shaped opening with respect to the driver in a central position as aligned with the rotary axis (D) of the handle and additionally has guide elements located along its outer circumference;
- wherein the detent ring is inserted into the guide sleeve with an opening in the detent ring serving as a receptacle for the driver- and guide elements of the detent ring engage with guide elements on the guide sleeve in an axially-movable fashion;
- wherein the installation body comprises a base body having a recess located therein which is aligned centrally with the rotary axis (D) of the handle, the base body also having at least two passage holes located therein which are arranged to serve as receptacles for fastening screws, and wherein the base body has a top side and a bottom side;
- wherein the installation body further comprises a covering element that is rotatably mounted on the top side of the base body, the covering element being moveable between a first rotary position with respect to the base body in which the covering element covers the base body and a second rotary position with respect to the base body in which the covering element allows access to the passage holes in the base body;
- wherein the covering element is rotatably mounted on the base body using a flange ring;
- and
- wherein the flange ring and the counter detent ring each have fitted key elements that are respectively arranged to facilitate the flange ring and the counter detent ring to engage each other in a non-twisting manner.
