    Abstract: This invention relates to a quarter point return mechanism for a manually driven revolving door. Revolving door leaves extending outwardly from a shaft are partially enclosed between opposed curved sidewalls. The return mechanism has a number of elements including an actuator, a rack arranged to be linearedly displaced by the actuator, and a pinion engaging the rack and being rotatable in opposite directions. The pinion is rotatably connected to the central shaft of the door. When the pinion is rotated in one direction, rotation is transmitted to the shaft. When the pinion is rotated in the opposite direction, the rotation is not transmitted to the shaft. Also included is a circumferential displacement sensor which operates the actuator when the outer ends of the door leaves are in a position circumferentially displaced from the sidewalls. The return mechanism returns the door leaves to a rest position in which the door leaves are in contact with the curved sidewalls.

    Abstract: A braking device for a moveable door leaf comprises an electrical brake motor being operated as a generator, the motor shaft of which is rotatable by a movement of the door leaf and which can be controlled for regulating the closing speed of the door leaf by means of an electronic evaluation and control unit, which is at least partially providable with electrical energy by an electric motor being operated as a generator, particularly the brake motor, and/or by means of an additional generator unit. The electronic evaluation and control unit is thus operable in a sleep mode and is cyclically displaceable into a waking state depending on the closing speed of the door leaf, wherein the wake-up frequency with which the electronic evaluation and control unit is cyclically awakened during a respective closing movement of the door leaf is less at relatively lower closing speeds of the door leaf than at relatively greater closing speeds of the door leaf. A door closer with a mechanical energy storage and a correspondingly designed braking device is also disclosed.

    Abstract: A door closing device (10) for an automatic closing of a door leaf (B) coupled with a floor and/or a doorpost (S) so as to swing. The door closing device (10) comprises a fixed unit (12) that is fixed on the floor and/or the doorpost (S), a translating unit (14) and a rotating unit (16) on which the door leaf (B) is fixed. The coupling of the three units (12, 14, 16) and the presence of spring (38) are such that, when the rotating unit (16) rotates in a first sense of rotation, the translating unit (14) is caused to translate in a direction and such that, when the translating unit (14) translates in an opposite direction, the rotating unit (16) is caused to rotate in an opposite sense of rotation.

    Abstract: A furniture drive is provided for driving a movable piece of furniture. The drive includes an electric motor, an actuator that can be moved back and forth between two end positions to apply a force on the piece of furniture to be driven, and a gearbox connected between the electric motor and actuator. The gearbox has at least one gear stage configured as an eccentric gearbox and includes two gear wheels that mesh with each other. One of the two gear wheels is firmly connected or coupled to the actuator, and the other gear wheel is coupled to the electric motor such that the eccentric gearbox has two limit positions which correspond to the end positions of the actuator. Upon a rotation of the gear wheels, starting from the limit positions, the gear ratio decreases over a deformed rotational angle range.
