Sink attachment for arranging on a sink

A sink attachment for arranging on a sink, comprising a coupling device for coupling the sink attachment to a coupling sidewall of a basin of the sink in a working position,

• wherein the coupling device comprises an inner coupling element that is configured to be seated, in the working position, on an inner side of the coupling sidewall facing the interior of the basin and comprises an outer coupling element that is configured to be seated, in the working position, onto an outer side of the coupling sidewall facing away from the interior of the basin,
• wherein the sink attachment comprises a second inner coupling element that is configured to be seated, in a second working position in which the sink attachment is rotated about an angle of 180° with respect to the first working position, onto the inner side of the coupling sidewall, and comprises a second outer coupling element that is configured to be seated, in the second working position, onto the outer side of the coupling sidewall,
• wherein the inner coupling element and the outer coupling element are arranged on a base body of the sink attachment, the base body having a supporting face, and wherein the sink attachment is formed substantially symmetrical with respect to a rotation of 180° about an axis of rotation running perpendicular to the supporting face of the sink attachment through the center of gravity thereof, and/or wherein the sink attachment is formed substantially mirror symmetrical with respect to a longitudinal medium plane of the sink attachment running parallel to a longitudinal direction of the sink attachment and perpendicular to the supporting surface of the sink attachment.

A combination comprising a sink having at least one basin and a sink attachment for arranging on a sink, comprising a coupling device for coupling the sink attachment to a coupling sidewall of a basin of the sink in a working position,

• wherein the coupling device comprises an inner coupling element that is configured to be seated, in the working position, on an inner side of the coupling sidewall facing the interior of the basin and comprises an outer coupling element that is configured to be seated, in the working position, onto an outer side of the coupling sidewall facing away from the interior of the basin,
• wherein the sink attachment is coupled by means of the coupling device to a coupling sidewall of the basin of the sink,
• wherein the sink attachment comprises a base body, on which the inner coupling element and the outer coupling element of the coupling device are arranged,
• wherein the inner coupling element and the outer coupling element, together with the base body, bound a receiving space for an upper rim region of the coupling sidewall, wherein an underside of the base body connects an upper edge of the inner coupling element facing the base body to an upper edge of the outer coupling element facing the base body, and
• wherein the underside of the base body in the working position of the sink attachment is spaced apart from the coupling sidewall of the basin.
