Claim:
A door closer ( 10 ) comprising: a frame bracket ( 7 ) and a door bracket ( 4 ); a spring-loaded cylinder ( 12 ) and piston rod assembly ( 16 ) extendable between an open and a closed positions; a door-waiter ( 34 ) pivotably supported adjacent a first end ( 18 ) of the piston rod ( 16 ) connected to one of the frame bracket and the door bracket; the door-waiter ( 34 ) is capable of retaining the spring-loaded cylinder ( 12 ) and piston rod assembly ( 16 ) by rotating about its pivotal support adjacent the first end ( 18 ) of the piston rod ( 16 ) and engaging an at least one radial step ( 66 ) formed along an inner wall of the door-waiter ( 34 ) with an end surface of the cylinder ( 12 ) allowing the door to be held in at least one partially opened position without full extension of the piston rod assembly; and wherein a release lever ( 82 ) is pivotably supported at a pivot joint adjacent the first end ( 18 ) of the piston rod ( 16 ) and a push rod ( 84 ) abutting the release lever ( 82 ) and positioned substantially axially aligned along the inner sidewall ( 37 ) between the door-waiter ( 34 ) and the cylinder ( 12 ) and the push rod ( 84 ) disengages the end surface of the cylinder ( 12 ) from the at least one radial step ( 66 ).
