The innovation be-triWi is one of several. Parts of existing fittings, with the use of which is made possible, simply and inconspicuously, for example Bar stool seats can be rotated fully over the fixed base. The fitting was also used for many other types of seating and seating other utility furniture where the turning of a piece of furniture is required.

Apart from the most widespread system, according to which bar stool seats can be rotated over a central column below, preferably made of steel or wood, which is either firmly anchored to the floor or can be provided with a protruding cross base for variable positioning, whereby for the purpose of When turning, a cylindrical cup is attached centrally under the karst support plate, into which a suitably prepared recess is introduced in the column, but whatever the presence of this central column as the extremely stable construction of this pin, on which the entire leverage of the loaded seat is printed, is a Rotary fitting consisting of two sheet steel disks is known, in which these round sheet steel disks are non-detachable in their center, but are screwed together so that they can be twisted against each other. The two steel discs must, then both on specially prepared, flat. Bar stool components are fastened by screwing. The proposed rotary fitting differs from the known fitting described by its considerably simpler design, and also he; its use makes its use less flexible.

transferred directly to the bar stool legs.

In the drawing, an AUsfahrungsWiTv der'Nerung is shown, for example. Figure 1 shows a bar stool with a raised seat part in perspective Representation, whereby the installation of the multi-part fitting is emphasized. Figure 2 shows the installation of the multi-part fitting in a vertical section

Screw connection, after first the Zapfen.® is passed through a prepared, drilled hole over time in the bar stool seat plate a permanent connection between the bar stool seat and the bar stool base. In order to have the possibility of rotating from seat to foot frame, it is allowed

The screw nut®, however, is only slightly removed. A possible, unprofitable The loosening of this screw nut (§) in long-term use of the bar stool can be prevented, preferably by applying a second screw nut or by subsequent riveting of the screw thread, as can be done, for example, by precisely guided hammer blows using a center pin on the threads.

While the bar stool seat and leg frame are held together by means of the metal plate® with its tenon® and the screw nut (6), a further possibility of this joining together can be achieved by pressing a threaded screw firmly into the seat plate by pressing between the screw head and the screw nut is fixed, the screw neck is passed through a sufficiently large hole in the metal plate (T), the application of another screw nut finally ensures the hold of the rotatable connection, guarantee for even and quiet turning of the bar stool seat as well as for picking up the when "occupying "this seat resulting leverage in a
