Patent ID: 7568239

Claim:
A combination of a sink and a sink accessory, which is adapted to be placed on the sink, wherein the sink accessory comprises an underside surface and a positioning element adjacent the underside surface, wherein the positioning element comprises at least a first bearing surface with which the sink accessory is placed, in a first position, on at least one first supporting surface of the sink, wherein the positioning element of the sink accessory comprises at least one second bearing surface, separate from the first bearing surface and the underside surface, with which the sink accessory is placed, in a second position, on a second supporting surface of the sink or on a supporting surface of another sink accessory, wherein the second bearing surface of the positioning element of the sink accessory is arranged at a different height level of the sink accessory than the first bearing surface and the underside surface, wherein the positioning element of the sink accessory comprises at least one lower surface, separate from the first bearing surface, the second bearing surface, and the underside surface, wherein the lower surface of the positioning element of the sink accessory is arranged at a lower height level of the sink accessory than the first bearing surface, the second bearing surface, and the underside surface when the sink accessory is placed in the first and second positions, wherein the positioning element of the sink accessory comprises: at least one first positioning surface separate from the first bearing surface and disposed at an angle thereto and separate from the second bearing surface and disposed at an angle thereto, which cooperates with a first positioning surface of the sink when the sink accessory is placed on the sink in order to fix the sink accessory in a working position relative to the sink, in order to guide the sink accessory in the course of a displacement relative to the sink along a direction of displacement or in order to limit the displacement path of the sink accessory relative to the sink, and at least one second positioning surface separate from the first bearing surface and disposed at an angle thereto and separate from the second bearing surface and disposed at an angle thereto, which cooperates with a second positioning surface of the sink or with a positioning surface of another sink accessory when the sink accessory is placed on the sink or on the other sink accessory in order to fix the sink accessory in a working position relative to the sink or relative to the other sink accessory, in order to guide the sink accessory laterally in the course of a displacement relative to the sink or relative to the other sink accessory along a direction of displacement, or in order to limit the displacement path of the sink accessory relative to the sink or relative to the other sink accessory, wherein the second positioning surface is arranged at a different height level of the sink accessory than the first positioning surface.
