Abstract:
A method for arranging a drive unit in a revolving door, the drive unit being arranged at a ceiling element of the revolving door and configured to drive a turnstile of the revolving door, includes: arranging an adapter element at the ceiling element; arranging an electronically commutated multipole motor at an adapter element; and adjusting, by the adapter element, the multipole motor relative to the turnstile of the revolving door.
Abstract:
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.
Abstract:
A swing leaf operator having a closer portion. The closer portion has an output shaft, on which a cam disc is torsion-resistantly disposed, as well as a pressure roller. A closer spring presses the pressure roller against a running surface of the cam disc. The pressure roller is disposed such that, during an opening or closing of a swing leaf coupled to the output shaft, the pressure roller is moved along a path. The path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, in different modes of operation of the swing leaf operator at a respective opening angle of the swing leaf, a very similar or identical torque is respectively applied to the output shaft. The swing leaf operator has a drive motor in operational connection with the output shaft.
Abstract:
The invention relates to linear drives (1), which are based on linear motors, for panels, in particular sliding doors, movable along a respective travel path.An inventive linear drive (1) for at least one panel, in particular a sliding door leaf (4), movable along a travel path, has at least one linear motor for this at least one panel. The linear motor is to provided with a stator member (3) and a carriage (2). Furthermore, the linear drive (2) has a control circuit. The control circuit is adapted to stop the linear motor in the event of failure of power supply to the linear motor, by means of switching-off the linear motor and operating it as a generator. Thereupon, in terms of its displaceability, this movable panel is enabled by the control circuit. In addition, the inventive linear drive (1) has switching means for switching-off the energy supply to the at least one linear motor.
Abstract:
A coil former for a linear motor stator for an automatic door having a coil arrangement, which, upon appropriate activation, is able to produce an interaction with a linear motor rotor, which causes thrust forces, with a body for the reception of a winding wire to form a coil, and at least one flange terminating the body at the front side, wherein the at least one flange of the coil former has at least one wire reception, which is able to receive a predetermined length of the winding wire and is able to, at least partially, release it again.
Abstract:
A suspension system for at least one panel movable along a travel path is disclosed. The suspension system has at least two carriages for the at least one movable panel. The at least two carriages are stationarily mounted at an upper section of the at least one movable panel and are disposed to extend essentially in a direction transversely to the travel path and parallel to a vertical extension of the at least one movable panel. Rollers are freely rotatably disposed at each carriage. The rollers are disposed to roll on a running surface of a running rail of the suspension.
Abstract:
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.
Abstract:
A hydraulic swinging-leaf door drive for swinging doors includes an actuating piston, which acts on a drive shaft. A hydraulic pump acts on the actuating piston by way of a hydraulic circuit. The hydraulic circuit is designed as a closed circuit.
