ABSTRACT:
A telescoping door closer or strut is disclosed wherein a sliding rod is automatically held at any desired position of extension or retraction with respect to an associated housing. An automatic brake and hold mechanism for retaining the rod in the desired position includes an annular disk-like brake mounted on the rod and pivotable from a transverse position where the rod slides freely therethrough and an oblique position where the rod is cramped and retained by the brake. One edge or side of the brake is restrained to cause it to pivot into the oblique position upon movement of the rod in a first direction. A stop attached to the housing engages the opposite side of brake to keep it in the transverse position upon movement of the rod in the opposite direction.
