Patent number: 8732904Abstract: A door closer is described, which has an output shaft, on which a cam disc is torsion-resistantly disposed, and has a pressure roller. By means of an operational connection, a closer spring presses the pressure roller against a running surface of the cam disc. In relation to an axial center of the output shaft, the pressure roller is disposed such that, during opening or closing of a swing leaf coupled to the output shaft, the pressure roller is movable along a path. Due to the fact that the path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, at a respective opening angle of the swing leaf, in different modes of operation of the door closer, a very similar or identical torque is respectively applied to the output shaft.Type: GrantFiled: December 11, 2007Date of Patent: May 27, 2014Assignee: Dorma GmbH + Co.

Patent number: 8572896Abstract: A linear drive for sliding doors, particularly linear drives based on linear motors. A linear drive, for at least one part which is movable along a movement path, particularly a sliding door leaf, has at least one linear motor for the at least one part. A stator part of the linear motor is received in a receiving profile so as to be prevented from falling out. The receiving profile is constructed to be arranged at a fastening device, which is arranged in turn on the installation side of a wall portion or top portion. Accordingly, the stator part and receiving profile form a module or unit, which can be mounted in its entirety. Therefore, a person performing the mounting can use the receiving profile for mounting, which helps to reduce the risk of damaging the stator part.Type: GrantFiled: August 15, 2008Date of Patent: November 5, 2013Assignee: Dorma GmbH + Co.
