  • Patent number: 6377010
    Abstract: A electromotive drive for a furniture item, in particular lifting device; includes a housing, a drive motor mounted to the housing, a reduction gear unit interacting with the motor, a rotating spindle driven by the reduction gear unit and carrying a spindle nut which is secured against executing a rotational movement so as to move in a linear direction. A flanged tube is mounted to the housing and accommodates a lifting tube which is mounted to the spindle nut so as to be movable between retracted and extended positions when the spindle rotates and the nut is moved in a linear direction. At least one gas spring is arranged within the flanged tube for assisting the lifting tube during a movement of the lifting tube to the extended position, with the gas spring having a piston rod which is movable in retracted and extended positions in synchronism with the lifting tube.
