ABSTRACT:
A sales and presentation area has an essentially annular region rotatably mounted in the horizontal direction, divided into ring segments able to be moved individually in the vertical direction, and set into horizontal rotational movement via drives during use of the ring segments by customers. A changing section along the path of the moving annular region is kept inaccessible for customers from the exterior of the annular region. A lifting and lowering device is provided beneath the changing section. The ring segments slide over the lifting and lowering device in the course of the rotational movement of the annular region and rest on the lifting and lowering device during a standstill of the annular region for moving the ring segments in the vertical direction. The ring segments may be pushed in the radial direction into rooms below the sales and presentation area.
