ABSTRACT:
A load bearing structural assembly comprising a threaded lead screw having a central axis, the lead screw having a mounting mechanism and an anchor mechanism affixed to one end thereof; the lead screw having mounted thereon a first drive nut having an opening therethrough, the first drive nut having a predetermined load bearing capacity, the structural assembly having a second drive nut having an opening therethrough the second nut affixed to the first drive nut, the second nut having a much greater predetermined load bearing capacity than the first drive nut; the structural assembly having a collet having an interior and exterior, the collet in communication with the exterior surface of the second drive nut upon the interior of the collet, having an opening therethrough, having a transmission mechanism affixed to the first drive nut and the collet, when the transmission mechanism subjects a load upon the first drive nut in a direction along the lead screw, such load will be subjected upon the collet which will further capture the second drive nut within the opening at the interior of the collet and force the second drive nut to clamp down on the lead screw sufficiently to prevent rotation of the lead screw and to pass the load from the transmission mechanism to the lead screw to the anchor mechanism, and from the anchor mechanism to the mounting mechanism, thereby resolving the axial loading of the lead screw.
