A positionally adjustable leg for a stand construction between two structures comprises a part lying against a first structure 5 and, at the other end, an attachment to the second structure 4. The leg of the stand construction is constituted by three arms 1, 2, 3, which are each arranged to support one of the structures against the other. The arms are articulately fixed to the end of the second structure 4 in such a way that they are pivotable relative to the structure 4 about at least two essentially parallel rotational axes B, B' running transversely relative to the longitudinal direction of the arm, the connecting distances between the hinge points of the arms forming a triangle on the end of the second structure 4. The arms are directed from their hinge points in the direction of the part 6 lying against the first structure 5, such that they converge. Each of the arms 1, 2, 3 is articulately fastened to the end of the part 6 lying against the first structure 5 in such a way that they are pivotable relative to the said part 6 about a rotational axis D running transversely relative to the longitudinal direction of the arm, at least one of the arms 1, 2, 3 being arranged such that it is variable in length. <IMAGE>
