US 9,834,955 B2 · Installation body for door and/or window handles

Abstract

An installation body used as an axially fixed and rotatable receptacle for a handle. The handle consist of a circumferential engagement groove in a neck section of the handle that is in contact with the installation body. The installation body is composed of a base body with a passage opening aligned centrally with an axis (D), a guide bushing for the neck section of the handle, whereas the guide bushing is arranged inside the passage opening of the base body and locking mechanism, which fixates the handle inside base body in a releasable manner. The locking mechanism uses locking balls, which are adjustable arranged radially in the direction of the axis inside the guide bushing. The latter is positioner the passage opening of the base body in a direction (A) in an adjustable manner, wherein the guide bushing, or the base body, has a circumferential inclined surface that is acted upon by a pressure spring the direction (A).

An installation body with an axially fixed and rotatable receptacle for removably receiving a handle, the handle being equipped with a circumferential engagement groove around a neck section thereof for engagement with the installation body, the installation body comprising:

a base body having a passage opening therein which is centrally located with respect to an axis, the base body having a circumferentially inclined surface located therein;
a guide bushing for the neck section of the handle, the guide bushing normally being positioned within the passage opening of the base body;
and
a locking mechanism for releasably locking the handle in place with the neck of the handle located inside the base body, the locking mechanism comprising:
a plurality of locking balls positioned inside the guide bushing in such a manner that they can be shifted radially with respect to the axis;
and
a pressure spring arranged to load the guide bushing in the axial direction, whereby the locking balls located inside the guide bushing are urged in the axial direction by the pressure spring causing the locking balls to be pushed against the inclined surface and move in a radially inward direction with regards to the axis to engage the circumferential engagement groove in the neck section of the handle when the neck section of the handle is inserted into the base body.
