Abstract
A portable, foldable surfacing module is disclosed for use by road vehicles as a road surface over previously impassable terrain. The surfacing module employs hinged sections that are rotatable through 360 degrees relative to each other and are foldable upon each other in accordian fashion for convenient storage, transport, deployment and retrieval.
Claims13
A folding surfacing module, comprising:
- first and second sections, said sections being essentially identical rectangular planar sections, each having attached at least one protruding annularly apertured shape longitudinally aligned along each of two opposing edges of the sections;
- at least one joining member interposed between said sections, said joining member having a pair of parallel annular apertures, the joining member being aligned between the sections such that one joining member aperture is in alignment with the protruding annularly apertured shape of one section and the other parallel joining member aperture is in alignment with the protruding annularly apertured shape of the other section;
- a first hinge pin to pivotably connect said first section with said joining member by being inserted into their aligned annular apertures;
- a second hinge pin to pivotably connect said second section with said joining member by being inserted into their aligned annular apertures.
1 more element
A portable roadway for use by road vehicles comprising:
- a multiplicity of essentially symmetrical planar sections of rectangular shape that are joined at opposing section edges by hinged coupling means that connect said sections in longitudinal alignment and allow the coupled sections to move through 360 degrees relative to each other to facilitate deployment or retrieval from a moving road vehicle and to accommodate said vehicle's travel over previously impassable terrain.
