Abstract

A supporting device for a data display unit (32) consists of a base plate (26) which can be swivelled about a vertical axis (24) and on which a supporting plate (30), on which the data display unit (32) stands, is longitudinally displaceable. A slide, which supports the bearing specifying the swivel axis of the base plate (26), is additionally linearly displaceable (38).

10. A supporting device as claimed in claim 1,

characterised in that the base part (26) is designed as a plate.

11. A supporting device as claimed in claim 10, characterised in that the guide between the base part (26) and the supporting part (30) is formed by guide grooves (50, 52) formed in the base plate top or by guide ribs which co-operate with guide rollers (88, 90) which are matched therewith and are mounted on the supporting part (30).

12. A supporting device as claimed in claim 1,

characterised by a friction wheel drive (70-74) which operates the rotatable part of the axial/radial bearing (64) and is supported by the slide (66).

13. A supporting device as claimed in claim 1,

characterised by a friction wheel drive (76-80) which is supported by the slide (66) and acts on the slide guide (58, 60) or a surface of the piece of furniture (18) that is parallel to the direction of movement of the slide (66).

14. A supporting device for a data display unit, which device is provided with a supporting part which is rotatable about a vertical axis and is displaceable in a horizontal plane and on which the data display unit can be placed, characterized in that the supporting part (30) is guided so as to be longitudinally displaceable on a base part (26) which, for its part, is connected via an axial/radial bearing (68;

102,

     104) having a vertical axis to a piece of furniture (10, 12;

18;

     44) provided with the supporting device, said axial/radial bearing being fitted on a slide (66;

     100) which runs on a guide (46,48;
