<p>The present invention is for a collapsible training device. The device comprises two vertical slide bars (2, 3) and along them movably arranged both a weight stack (1) and a carriage (9) by which various parts of the training device may be connected to the weight stack. The weight stack (1) comprises several plates which at their outer ends are movably arranged at the slide bars. Each plate of the weight stack has at its outer end an essentially semi-circular slide bushing for contacting against the respective slide bar (2, 3). The device also comprises a sitting board which may be set at any selected height by support legs. The support leg means comprises one into the other telescopically displaceable upper and lower leg whereby the outer legs (32, 33) are permanently joined to each other by at least one bar (28) having one on the bar movable catch (34) which is arranged to cooperate with slits (31) at the inner legs (29, 30). <IMAGE></p> |
