The invention relates to a self-assembling telescopable structure comprising a plurality of members which can be slipped and unslipped into and from each other. For the assemblage and disassembling of the structure releasable fastening members are provided for the several component parts and reversible lifting means acting between the internal component part and its next intermediary component part. By outstretching such means it is possible to effect the unslipping of the internal component part from its next. By subsequently fastening the internal component to the external one or to an intermediate component and binding mutually the other intermediate components, it becomes possible, by contraction of said lifting means to have the mutually bound intermediate components into the unslipped internal component part. By repeating these steps, the structure is assembled, whereas, by reverting the step sequence the disassembling of the structure is obtained.
A self-assembling telescopable structure comprising a plurality of component parts each having a height substantially equal for all of them, and which can be slipped and unslipped into and from an external component part, intermediate component parts and innermost component part, characterized in that there are provided first releasable fastening means between the top ends of the component parts when they are slipped into one another, second releasable fastening means between the top end of the innermost component part and the top end of any of the intermediate and the outermost component part when the innermost component part is slipped from its next intermediate component part, third releasable fastening means between the top end of each component part, the innermost one excepted, and the bottom end of the next intermediate or innermost component part, and reversible lifting means acting between the top end of the innermost component part and the bottom end of the next intermediate component part adapted controllably to cause the unslipping of the innermost component part from the next intermediate component part and the slipping of the innermost component part into its next intermediate component part, said third fastening means comprising angle members and means for releasably affixing same to the associated components.
