Pivot drive and piece of furniture

A pivot drive for a movable piece of furniture has an actuating arm which is mounted so that it can be pivoted about an axis of rotation, a spring assembly having at least one spring guided linearly in one working direction and a pressure-exerting component connected to the spring assembly and movable along a control curve, and a housing on or in which the pivot drive is mounted and a piece of furniture.

Drive unit

A drive unit for closing a leaf of a door or a window comprises an energy accumulator for providing a closing force for closing the leaf, a damping device which counteracts the closing force and has an electric motor which can be operated as a generator and can be coupled to an actuating element of the drive unit, and a control device for controlling the electric motor. The control device is designed to determine a nominal path curve which indicates a position of the leaf or a closing speed of the leaf in dependence upon time, and to perform the control of the electric motor in order to damp the closing movement of the leaf on the basis of the established target path curve.

Clamping bar arm for concealed door closer
10815713 · 2020-10-27 ·

A clamping bar arm for a concealed door closer preferably includes a mounting base, an adjustment arm, a clamp block, a pair of clamp fasteners and a pair of adjustment fasteners. The mounting base includes a mounting plate and an adjustment extension. The pair of adjustment fasteners are threaded through the adjustment extension. A pivot pin is inserted into a top of the adjustment extension. The adjustment arm includes a clamp arm and a stop projection, which extends downward from one end of the adjustment arm. A closer spindle notch is formed in an opposing end of the clamp arm to receive a closer spindle of a concealed closer. The clamp block is secured to an opposing end of the adjustment arm with a pair of clamp fasteners. An adjustment pivot hole is formed through the clamp arm to receive the pivot pin.

Braking device

A braking device for a movable door wing comprising an electric motor operated as a generator wherein its motor shaft is rotatable by a movement of the door wing and which outputs a motion-dependent motor voltage, and a braking circuit to which the motor voltage is applied or can be applied and via which the electric motor can be short-circuited in order to dampen a movement of the door wing. In addition, it is provided that the braking device comprises a safety device with a current sensor which is designed to detect amperage generated by the electric motor. The safety device is designed to modify the braking circuit depending on the detected amperage in such a way that upon reaching or exceeding a predetermined or predeterminable overload amperage, the current in the braking circuit is reduced.
