Abstract
A handle ( ) supported pivotably but axially tight on an installation body ( ) has a polygonal bar ( ) mounted for rotation within a handle neck ( ) for actuating a closing mechanism. Two drivers ( ) movable relative to each other are engageable in a non-positive and/or a positive way between neighboring surfaces ( ) either directly or by means of coupling elements ( ) so that a torque transmission from the handle ( ) to the polygonal bar ( ) is free but is blocked from the polygonal bar ( ) to the handle ( ) as at least one coupling element ( ) is displaced in the direction of the attack. A main portion of a polygonal driver ( ) may be concentrically enclosed by a two-shell handle driver ( ) having wings ( ) with front faces ( ) which drive e.g. pairs of spring-loaded roller pins ( ) held in a wedge-shaped confining zone ( ). Corner areas of indentations ( ) of the polygonal driver ( ) serve to attack the roller pins ( ). Central parts ( ) of the handle driver ( ) may guide a compression spring ( ) which loads engaging balls ( ) in an outward direction; recesses ( ) of the installation body ( ) are associated to the balls ( ) at enclosing surfaces ( ).
