Abstract
A furniture drive for moving a furniture front relative a furniture carcass includes a base body to be fixed to the furniture carcass, and an actuating arm pivotally supported on the base body about at least one first pivoting axis in a mounted condition. The actuating arm includes a plurality of levers hingedly connected to one another, and at least two of the levers of the actuating arm are configured to be releasably connected to the base body of the furniture drive. At least the levers of the actuating arm are symmetrically arranged with respect to a notional middle plane of the actuating arm.
Claims32
A furniture drive for moving a furniture front relative to a furniture carcass, the furniture drive comprising:
- a base body to be fixed to the furniture carcass;
- and
- an actuating arm pivotally attached to the base body about a first pivoting axis in a mounted condition, the actuating arm including a plurality of levers hingedly connected to one another,
- wherein at least two of the levers of the actuating arm are configured to be releasably connected to the base body of the furniture drive, and the plurality of levers of the actuating arm are symmetrically arranged with respect to a notional middle plane of the actuating arm, the notional middle plane extending along a length of the actuating arm and being perpendicular to a width direction of the actuating arm, and
- wherein:
- at least two of the levers of the actuating arm, in at least one pivoting position of the actuating arm are nested into each other, so that the at least two of the levers are arranged in a gap-free manner relative to one another in a side view;
- or
- at least one of the levers is U-shaped in a cross-section, and another of the levers is configured to be at least partially arranged between vertical limbs of the U-shape.
