Abstract: A self-cleaning handle, in particular a door handle, door knob or similar, includes a handle surface which can be rotated by a drive in relation to a cleaning unit, to perform a self-cleaning process. To achieve simple construction and operation, the handle surface is configured from a large number of surface segments, which are arranged around the periphery of a cleaning unit, and these surface segments can be rotated about their longitudinal axes.

Abstract: A device for gathering and compacting compactible goods such as paper towels, includes a housing provided with an opening for supplying the goods, with a holder for acccomodating the compactible goods and a compacting element that is pivotable about an arbor and which extends above the holder. The goods between the holder bottom and the compacting element are compactible by means of the compacting element. A drive extends from the compacting element which, to pivot the compacting element, and meshes with a denticulated element that curves about the arbor, serving as a center of curvature.

Abstract: The invention relates to a device for cleaning a toilet seat (12). In order to achieve a satisfactory cleansing consuming as little energy as possible, the inventive device comprises a mobile cleaning unit (18) which can be moved along the toilet seat (12) by means of water power.

Abstract: The invention relates to a device (10) for gathering and compacting compactible goods such as paper towels. Said device comprises a housing (12) provided with an opening (14) appointed for supplying the goods, with a holder (16) for holding the compactible goods, and with a compacting element (18). Said compacting element extends above the holder, can pivot around an arbor (22) and can compact the goods between the holder bottom and the compacting element. The aim of the invention is to permit, with a high degree of reliability, a problem-free compacting of goods using constructively simple measures. To this end, the invention provides that a drive (34) with a gearing (36) exits the compacting element (18). In order to pivot the compacting element, said gearing meshes with a denticulated element (42) that curves around the arbor (22) serving as a center of curvature.
