HEIGHT ADJUSTABLE STOOL

Abstract: Height adjustable stool with a seat (6) mounted on a vertical profile (2) which is connected to an underbody or a legs (5), where the profile (2) is vertically displaceable in section in square case (1) fastened in the underbody, in that the profile (2) has at least two legs protruding from the center of the case (1) towards two corners in the case (1) and that a screw (4) through the case (1) is adapted to, at tightening, to press against the center of the case (1) so that the legs of the profile (2) are wedged against the inside corners of the case.

Description: Height adjustable stool The present invention relates to a height adjustable stool. Height adjustable stools exist in many different principles, some with screw threads as in previous piano stools, and some with various other principles for adjustability. The stool according to the present invention provides a height adjustable stool with the veiy simple and safe principle. The stool according to the present invention is defined with the features set forth in the claims. The drawing shows on figure 1 a side view of a stool with the seat in the lower position, figure 2 shows a corresponding side view with the seat lifted, and figure 3 shows a section III-III in figure 2. The stool includes an under body or legs 5 which surround and are fastened to a case 1. Inside the case 1 a vertical profile 2 is arranged having a seat 6 fastened to the top. The vertical profile 2 can advantageously be formed of two angles each of which with the tip against the other, while the legs of one angle rest against the corresponding right angles in the case 1 and the legs of the other angle rest against the opposite other angles in the case 1. A screw 3 with a gripping handle 4 runs through the vertical part of a leg 5 and through the case 1. The inside end of the screw 3 rests against the inside corner of one profile 2. The end of the screw 3 can advantageously be pointed to dig into the profile 2 while tightened. Tightening of the screw 3 will cause the profile 2 to press so strongly against the opposite wall of the case 1, that the profile is wedged in the inside corner of the case 1, and thereby assure that the seat 6 will not be able to be moved, even if a person sits on the seat 6. By loosening of the screw 3, on the other hand, can the seat 6 with the profile 2 simply be adjusted to the desired height, whereupon the screw 3 again is tightened and locks the seat in this position.

Claims: Patent Claim Height adjustable stool with a seat (6) mounted on a vertical profile (2) which is connected to an underbody or a legs (5), characterized in that the profile (2) is vertically displaceable in section in square case (1) fastened in the underbody, in that the profile (2) has at least two legs protruding from the center of the case (1) towards two comers in the case (1) and that a screw (4) through the case (1) is adapted to, at tightening, to press against the center of the case (1) so that the legs of the profile (2) are wedged against the inside comers of the case.
