Door closer mounting arrangement
First Claim
1. An arrangement for mounting a door closer to a stationary or movable door frame having a channel rail, characterized in that the channel rail is provided with longitudinally extending undercut grooves, the undercut grooves form transversely extending guide means, means are provided for suspending the door closer at the channel rail, at least a portion of said suspending means is adapted to be received in the undercut grooves behind the transversely extending guide means, and means adapted to be supported at the door closer are provided for alignment with an end face of the channel rail for exact positioning of the door closer along the channel rail and for pressing said suspending means against said transversely extending guide means so as to securely position the door closer relative to the channel rail.

Abstract
An arrangement for mounting a door closer to a stationary or movable door frame. The door frame is provided with a channel rail having longitudinally extending undercut grooves which form transverse guide tongues. Guide projections provided on the door closer are adapted to be received in the undercut grooves so as to be disposed behind the guide tongues. At least one thumbscrew is supported at the door closer and arranged so as to press the guide projections against the guide tongues to thereby mount the door closer at the channel rail.
