Abstract

A sink includes a basin including a base wall and lateral walls adjoining the base wall. The basin includes a receiving area which is delimited by the base wall and the lateral walls. An insert plate separate from the basin is inserted into the receiving area. A lifting device is configured to move the insert plate relative to the basin in a height direction and includes a lifting unit with a variable length. The lifting unit includes a lifting mechanism which is embodied as a feed chain or a spindle drive.

First claim

The invention claimed is:

1. A sink, comprising:
a basin including a base wall and lateral walls adjoining the base wall, said basin including a receiving area delimited by the base wall and the lateral walls;
an insert plate separate from the basin and inserted into the receiving area; and
a lifting device configured to move the insert plate relative to the basin in a height direction, said lifting device including a lifting unit with a variable length, said lifting unit including a lifting mechanism embodied as a feed chain or a spindle drive,
wherein the lifting device includes a receiving housing arranged under the base wall, and wherein the feed chain or the spindle drive is arranged in an interior of the receiving housing when the lifting device is in a retracted position.

2. The sink of claim 1 , wherein the lifting unit includes a housing which circumferentially surrounds the lifting mechanism, said housing formed from multiple housing segments which are movable relative to one another in the height direction.

3. The sink of claim 2 , wherein the housing segments are rigid.

4. The sink of claim 2 , wherein the housing segments form a telescopic housing as the housing.

5. The sink of claim 1 , wherein the lifting device includes a motor for driving the lifting mechanism, said motor being arranged in the receiving housing of the lifting device.

6. The sink of claim 1 , wherein the base wall has an opening for passage of the lifting unit such that the lifting unit it is arranged on both sides of the opening.

7. The sink of claim 6 , wherein the opening is provided in a central location of the base wall.

8. The sink of claim 1 , wherein the lifting device includes a separate attenuation unit to acoustically decouple the lifting device from the base wall.

9. The sink of claim 8 , wherein the attenuation unit is a rubber attenuator or an acoustic foam.

10. The sink of claim 8 , wherein the attenuation unit rests directly on a lower surface of the base wall and is connected to the receiving housing of the lifting device.

11. The sink of claim 1 , wherein the insert plate has an upper surface with a surface area which is at least 80% of a surface area of the receiving area in a horizontal plane, but is less than 99% of the surface area of the receiving area.

12. The sink of claim 1 , wherein the insert plate has an upper surface with a surface area which is at least 90% of a surface area of the receiving area in a horizontal plane, but is less than 99% of the surface area of the receiving area.

13. The sink of claim 1 , wherein the insert plate has an upper surface with a surface area which is at least 95% of a surface area of the receiving area in a horizontal plane, but is less than 99% of the surface area of the receiving area.

14. A sink, comprising:
a basin including a base wall and lateral walls adjoining the base wall, said basin including a receiving area delimited by the base wall and the lateral walls;
an insert plate separate from the basin and inserted into the receiving area; and
a lifting device configured to move the insert plate relative to the basin in a height direction, said lifting device including a lifting unit with a variable length, said lifting unit including a lifting mechanism embodied as a feed chain or a spindle drive,
wherein the spindle drive includes at least two separate spindles which are coupled to one another.

15. The sink of claim 14 , wherein the at least two separate spindles are guided into one another.

16. The sink of claim 14 , wherein the lifting device includes a cover, said insert plate being arranged on the cover, wherein an upper one of the at least two separate spindles has an upper end which is connected to the cover.

17. The sink of claim 16 , wherein the cover is a cover plate.

18. The sink of claim 16 , further comprising an infinite rotation unit, said upper one of the at least two separate spindles being connected in one of two ways, a first way in which the upper one of the at least two separate spindles is connected to the cover by the infinite rotation unit such that, when the lifting unit is raised in the height direction, the upper one of the at least two separate spindles is infinitely rotatable relative to the cover about an axis of rotation which is oriented in the height direction, a second way in which the upper one of the at least two separate spindles is connected to the cover in a rotationally fixed manner and the upper one of the at least two separate spindles is connected infinitely rotatably to another one of the at least two separate spindles of the spindle drive.

19. The sink of claim 18 , wherein the infinite rotation unit is a ball bearing.

20. A sink, comprising:
a basin including a base wall and lateral walls adjoining the base wall, said basin including a receiving area delimited by the base wall and the lateral walls;
an insert plate separate from the basin and inserted into the receiving area; and
a lifting device configured to move the insert plate relative to the basin in a height direction, said lifting device including a lifting unit with a variable length, said lifting unit including a lifting mechanism embodied as a feed chain or a spindle drive,
wherein the lifting device incudes a receiving housing which is arranged underneath the base wall, said lifting device including a motor for driving the lifting mechanism, said motor being arranged in the receiving housing of the lifting device, and
wherein the spindle drive includes at least two separate spindles which are coupled to one another, said motor being connected to a lower one of the at least two separate spindles such that the lower one of the at least two separate spindles is movable by the motor in a rotation about an axis of rotation oriented in the height direction.
