Abstract:
1. A pivot fixture for pivotable parts comprising a guide unit ( 20 ) with a guide tube ( 22 ) and an arrest unit ( 40 ) with an engagement rod ( 41 ) slidably disposed in the guide tube ( 22 ), the guide tube ( 22 ) having an adjustment area ( 25 ), and the engagement rod ( 41 ) being provided with conical control cam structures ( 54 ) oriented in a longitudinal direction ( 5 ) and formed on, or fixed to, the engagement rod ( 41 ) for movement therewith, an expansion body ( 71 ) with a friction surface ( 94 ) slidably disposed on the engagement rod ( 41 ) and the friction surface ( 94 ) being arranged adjacent an inner wall section ( 23 ) of the guide tube ( 22 ) and abutting the inner wall section ( 23 ) when the expansion body ( 71 ) is disposed in the adjustment area ( 25 ), the control cam structure ( 54 ) having inclined control surfaces ( 58 , 59 ) which are conically inclined in opposite directions so as to form a central bulge and the expansion body ( 71 ) having a constricted area ( 79 ) with inclined engagement surfaces ( 81 , 82 ) extending axially from the constricted area ( 79 ) so as to form widening conical engagement surfaces extending in opposite directions from the constricted area ( 79 ) through which the engagement rod ( 41 ) with the control cam structure ( 54 ) extends for expanding the expansion body ( 71 ) into engagement with the guide tube ( 20 ) when the control cam structure ( 50 ) enters the expansion body ( 71 ) from either side of the constricted area ( 79 ) thereof and a return spring ( 101 ) arranged between, the expansion body ( 71 ) and the engagement rod ( 41 ) on which the expansion body ( 71 ) is axially supported.
