  • Patent number: 8272907
    Abstract: A sectionalized sports board including a plurality of board sections and a post-tensioning apparatus incorporated into a board stringer and operatively disposed between the sections along the longitudinal axis of each section. The post-tensioning apparatus includes a post-tensioning cable slidably inserted into a cable chase disposed in each of the board sections, and a cable tension adjustment for selectively coupling the sections into a configuration for use of the board or for separating the board sections so that they can be folded into a compact collapsed configuration. The post-tensioning cable is permanently anchored at its ends, and when the post-tensioning cable is in a stressed condition, the board sections are abutted to provide a useable and rigid board configuration, and when the post-tensioning cable is unstressed, the board sections may be folded into a compact collapsed configuration.
