The overflow is integrated in the divider and the recess is preferably formed integrally from the divider. Manufacturing, assembly and cleaning costs are reduced. The recess and thus the arranged on her overflow are from accessible to both sinks.

Through the recess, a substantially horizontal surface is formed, which connects the adjacent side walls of the two sinks together and has overflow openings.
For example, the overflow openings are substantially vertically aligned. The opening area of the overflow openings corresponds to the regulations or recommendations regarding the overflow volume flow to be guaranteed. The horizontal surface preferably extends from the side wall of the first sink to the associated side wall of the adjacent sink. The horizontal surface extends in the longitudinal direction parallel to the separating web, preferably by a multiple of the distance between the two side walls.

In the area of the recess is on the bottom of the sink Overflow connection piece fixable, to the one overflow line is connectable. The overflow pipe can through a hose or a Be formed tube. The overflow connection can ribs for Plugging the overflow line or a connecting element to the Have connect the overflow line. Preferably the overflow line detachably connectable.

The spill port is from the top of the sink by means of a through a hole in the recess passing through the fixing means releasably fixable. The fixing means may for example by a Threaded sleeve may be formed with an external or internal thread in the overflow connecting piece can be screwed.

The recess can be covered with a cap whose shape matches the contour of the recess adjacent region of the divider is adjusted. The cap can be made of plastic, aluminum or stainless steel, for example exist and preferably has rounded edges to the risk of injury, especially during assembly and / or the Prevent cleaning.

The cap is releasably attachable or detachable in the separating web or the recess can be inserted. As a result, the assembly and / or Cleaning costs reduced.

In the cap is an elastically deformable expansion leg exhibiting Spreizbolzen screwed, which when attaching the cap on the Divider by means of the expansion leg in a predetermined position is latched. The expansion pin is preferably in one of the cap fixed, for example glued or welded, or in one piece formed by the cap threaded bolt, an interior or Having external thread, screwed. By the screwing is the cap in terms of their height and thus their distance to that of the recess formed horizontal surface adjustable.

The cap defines together with the recess or with the of the Recess formed horizontal surface the overflow volume flow determining overflow opening surfaces. By the possibility of Height adjustment of the cap is also the overflow volume flow adjustable.

The sink is preferably made in one piece, whereby the manufacturing cost is reduced. Preferably, the sink is made of a Composite produced, at least partially one Polymer plastic has. Such composites are becoming common also referred to as composite materials and can in addition to a Binding material have a silicate filler material.
