In the case of a height-adjustable piece of furniture other than the one above, there is a seter-like arrangement as the adjustment mechanism, which can be adjusted with spindles or also as power pumps and springs -cherenwinlceXs. the ■ des itotri; © Bs & raftw © g © 0 zmt Itesstellwög uM iSöisit die zu

Finally, a height-adjustable table is known in which between two cheek-like legs, which remain on the floor and are connected to each other, and the height-adjustable table parts, springs are arranged. Locking and unlocking take place step by step with the help of a snub bar, which engages in bores perpendicular to the direction of movement. One disadvantage of this arrangement is that with unequal loads: the springs are unevenly pressed against each other. and so the 3? ica at uen two leg © "unequal raises .senkt respectively *." so that the elevating parts jam in their guides, txa & daii on the other hand a in © continuous bin division _v the table height is not iaöglieh; Asleep borrowed is a high verse divisible
