ABSTRACT:
A door closer and a connector are joined to a door panel and a door frame. The connector includes an arm and a restraining device such as a track or a link. The arm has an arm base fast on a shaft projecting from the closer for rotation about a first axis and has an arm extension at one end connected to the restraining device and at the other end pivoted to the arm base for rotation relative thereto about a second axis parallel to and spaced from the first axis. A shoulder on the arm base and an abutment on the arm extension come into contact in one position of relative rotation of the arm base and the arm extension. If desired, there may also be a locking device engaging both the arm base and the arm extension and precluding relative rotation therebetween about the second axis. Further, there may be a damping device such as a friction brake for partially inhibiting relative rotation about the second axis.
