Abstract
A handle (10) supported pivotably but axially tight on an installation body (20) has a polygonal bar (30) mounted for rotation within a handle neck (12) for actuating a closing mechanism. Two drivers (15, 35) movable relative to each other are engageable in a non-positive and/or a positive way between neighboring surfaces (17, 37) either directly or by means of coupling elements (36, 40, 42) so that a torque transmission from the handle (10) to the polygonal bar (30) is free but is blocked from the polygonal bar (30) to the handle (10) as at least one coupling element (36) is displaced in the direction of the attack. A main portion of a polygonal driver (35) may be concentrically enclosed by a two-shell handle driver (15) having wings (52) with front faces (19) which drive e.g. pairs of spring-loaded roller pins (36) held in a wedge-shaped confining zone (55). Corner areas of indentations (31) of the polygonal driver (35) serve to attack the roller pins (36). Central parts (50) of the handle driver (15) may guide a compression spring (38) which loads engaging balls (47) in an outward direction; recesses (27) of the installation body (20) are associated to the balls (47) at enclosin…
