A pull-out guide for drawers has a carcass rail, a drawer rail, and a central rail which is moveably mounted between the carcass rail and the drawer rail. At least one carriage is mounted in a moveable manner between at least two rails of the pull-out guide. A synchronization apparatus avoids running faults of the pull-out guide, and the synchronization apparatus has at least one synchronization wheel which interacts firstly with the one carriage and secondly with a running surface which is arranged on one of the rails. The synchronization wheel is in the form of a gear with two pinions with different diameters. The first pinion and the second pinion are connected to one another in a rotationally fixed manner, wherein, when one pinion moves, the other pinion also moves.

Pull-out guide for drawers

The invention relates to a flap drive system for a flap which is movably mounted on a furniture carcass. The flap drive system is arranged on a sidewall of the furniture carcass. The flap drive system includes a mechanical actuating unit having an actuating arm that can be connected to the flap and an accumulator acting upon the actuating arm, and an electric drive, fastened on the mechanical actuating unit for driving the flap. The electric drive has at least one electric motor, and a gear stage which allows the transmission of force from the electric drive onto the mechanical actuating unit. The gear stage is designed as a separate component, and has a housing that is independent from the mechanical actuating unit and the electric drive or an independent mounting plate.

Flap drive system

The invention relates to a furniture flap drive comprising an electric drive having an electric motor and a mechanical actuating unit having an actuating arm, the mechanical actuating unit and the electric drive being separate components and being releasably fastenable to each other. The actuating unit has a bearing in which the electric drive can be suspended, the suspended electric drive being swivelable about the bearing towards the actuating unit. A locking device is mounted at a distance to the bearing and can be used to lock the electric drive, in a preferably releasable manner, with the actuating unit once the latter has been swiveled open.

Furniture flap drive that can be swiveled open

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.

Furniture drive for driving a movable furniture part

A furniture flap drive is provided with a first component having an electric motor and with a second component having an adjustment arm, wherein the first component and the second component can be fastened releasably to each other, and a force transmission device is provided to move the adjustment arm, wherein a positioning device can be used to adjust the position of the force transmission device, and wherein the first component can be fastened to the second component in at least two, preferably at least three, different positions of the adjustment arm.
