Abstract

This telescopic tube (10) consists of a first and a second continuous band (32, 36), wound respectively spirally and helically, with the turns of each band resting flat against one another in the retracted position of the tube. The turns of the respective bands are at right angles to one another. In order to lengthen the tube, the turns of the first band are spaced apart from one another, and the turns of the second band are inserted between the spaced-apart turns of the first band, so as to act as spacers for these latter turns. A mechanism is described here which produces the lengthening and the retraction of the tube, which is used especially as a pushing jack (10). <IMAGE>
