Abstract
An arrangement of a pull-out guide can be fastened to a piece of furniture, and the pull-out guide has a first rail, a second rail that is movably mounted on the first rail, and a rail synchronization device. The rail synchronization device includes a toothed rack connected to the first rail, a toothed wheel meshing with the toothed rack, and a bearing block connected to the second rail. The toothed wheel is rotatably mounted in the bearing block, and a driver for a drawer drive device is connected to the toothed rack of the rail synchronization device.
Claims22
An arrangement comprising:
- an extension guide to be fastened to an item of furniture, the extension guide including a first rail and a second rail movably mounted on the first rail;
- a rail synchronization device including a toothed rack connected to the first rail, a toothed wheel meshing with the toothed rack, and a bearing block connected to the second rail, the toothed wheel being rotatably mounted in the bearing block;
- and
- an entrainment member fixed to the toothed rack so as to be immovable relative to the toothed rack, the entrainment member comprising an entrainment plate and an entrainment pin on the entrainment plate so as to be immovable relative to the entrainment plate, the entrainment pin being configured to engage a drawer drive device,
- wherein the toothed rack rests on the entrainment member such that the entrainment member supports the toothed rack, and
- wherein the bearing block receives the toothed rack so as to support a portion of the toothed rack such that the toothed rack is free of any direct support between the entrainment plate and the bearing block.
