Office equipment comprising a supporting member and a top adjustable in height

Abstract

Abstract For the height adjustability of the plate (2), two toothed wheel lifting gears (6, 7) are attached to a support part (1). These gears (6, 7) are composed of a threaded shaft (9), two toothed wheels (10, 11) in engagement with said threaded shaft and a smooth auxiliary shaft (12). The plate (2) is supported on shaft pieces (13, 14) of the toothed wheels (10, 11) by a bearing. The shaft pieces (13) of the one toothed wheel (10) are coupled to each other by a connecting shaft (15). Installed on the connecting shaft (15) is a backgear (17), the drive shaft (18) of which permits the height adjustment of the plate (2) by means of a crank (19). Since only two toothed wheel lifting gears (6, 7) are arranged on the support side, the plate (2) can be constructed as an unsupported component. <IMAGE>
