A driver device for a panel to be moved along a travel path is disclosed. The driver device has a driver member, which is adapted to be stationarily mounted to a member guided along the travel path. Furthermore, the driver device has a spring element, which is mounted to the guided member and is propped up at a side of the panel to be moved facing the guided member. At least with regard to a direction of the pre-tensioning of the spring element, the driver member is loosely coupled to the panel to be moved. The spring element is pre-tensioned such as to press the guided member and the driver member away from each other.

A magnetic drive system for driving a door leaf in a driving direction is disclosed. The drive system includes a row of magnets disposed in the driving direction and having a longitudinal direction, the magnets being arranged so that magnetizations of the magnets reverse in accordance with a predetermined pattern; and a coil arrangement comprising a plurality of coil cores and a plurality of coils, the coils being wound around respective coil cores and spaced apart from each other in the longitudinal direction of the row of magnets. When energized, the coils interact with the magnets to generate a thrust force for driving the door leaf in the driving direction. The magnets in the row of magnets are disposed relative to the coil cores so that a total magnetization of the magnets has no abrupt polarity reversal in the driving direction with respect to the coil cores.

A magnetic drive system for a door leaf is disclosed. The drive system includes a carrying slide for carrying the door leaf; a row of magnets disposed in the driving direction and having a length L and a longitudinal direction, the magnets being arranged so that magnetizations of the magnets reverse at a predetermined interval in the longitudinal direction; a coil arrangement comprising coil cores and coils which are wound around respective coil cores; and a displacement measuring system comprising a first magnetically sensitive position sensor and a second magnetically sensitive position sensor which is separated from the first position sensor by a distance A. The distance A is larger than the difference between the length L and the travel path V and smaller than the length L.

A linear drive based on linear motors, for panels, in particular sliding doors, movable along a respective travel path. A linear drive for at least one panel, in particular a sliding door leaf, movable along a travel path, has at least one linear motor for this at least one panel. The linear motor is provided with a stator member and a carriage. Furthermore, the linear drive 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 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 linear drive has a switch for switching-off the energy supply to the at least one linear motor.

A suspension for at least one panel, which is movable along a travel path, has a guiding profile configured to longitudinally extend along the travel path and to have sidewall sections. The sidewall sections are configured to extend in a direction of the longitudinal extension of the guiding profile and parallel to a vertical extension of the movable panel. In addition, at an end facing away from the movable panel, the sidewall sections are connected to each other by means of a horizontal wall section. At an end facing the guiding profile, the at least one movable panel is received in a guided and supported manner in the guiding profile. A driver member of a linear drive system is operatively connected to the movable panel. In the guiding profile, in a space between the horizontal wall section and the driver member, a reception space is formed, into which a driving profile is fitted and stationarily mounted to the guiding profile, the linear drive system, at least partially, being accommodated in the driving profile and the driving profile being disposed in the guiding profile above a guide of the movable panel.

摘要:
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.
