ABSTRACT:
A power cell for lifting masses by inflation of the cell by a gaseous or liquid medium, the cell being hollow and, in the pressure-free state, substantially a single plane. The cell includes two parallel polygonal surfaces, preferably squares, invariant in shape, interconnected by wall segments which vary in shape as the cell is inflated, the side wall segments forming partial cylindrical surfaces. The side wall segments and the polygonal surfaces are joined by transition wall surfaces to form a closed body. Various embodiments of the transition wall surfaces forming corner segments, are disclosed, wherein, in the pressure-free state of the cell, the extensions of the peripheries of adjoining side wall segments may intersect substantially rectilinearly, in a convex arc, in a concave arc, or in an obtuse angle.
