Abstract:
An adjustable base structure comprising:a. a plate having a center region; b. means for supporting a selected object on the plate center region; c. at least three legs each having first and second ends; d. a pivotal connection between the first end of each leg and the plate; e. a flexible cable having a predetermined total length consisting of a selected first length and a selected second length, the cable connecting to said at least three legs; and f. means for storing the cable first length inside a selected leg and connecting the legs with the cable second length and thereby independently adjusting the pivoting of said at least three legs to an operative mode in which the relative positions of the legs are dependent on the selected cable first and second lengths, so that the legs are independently pivotable relative to each other and to the plate to enable placement of the second ends of the legs on uneven terrain with the plate being oriented substantially horizontal.
