US5275502A — Accordian folding surfacing module

Claim 1

Independent Claim 147 words

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.

Claim 2

Dependent Claim 147 words

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.

Claim 3

Dependent Claim 28 words

The surfacing module of claim 1 wherein the sections are connected such that the sections may rotate through an angle of 360 degrees with respect to each other.

Claim 4

Dependent Claim 11 words

The surfacing module of claim 1 wherein the sections are ridged.

Claim 5

Dependent Claim 19 words

The surfacing module of claim 1 further comprising securing means to secure each hinge pin in its inserted position.

Claim 6

Dependent Claim 18 words

The surfacing module of claim 1 further comprising several essentially identical sections similarly connected to form a roadway.

Claim 7

Dependent Claim 26 words

The surfacing module of claim 5 wherein the surfacing module may be folded upon itself such that the sections are all in a relatively stacked orientation.

Claim 8

Dependent Claim 22 words

The surfacing module of claim 1 wherein the protruding annularly apertured shapes of the sections have an exterior shape that is lobed.

Claim 9

Dependent Claim 41 words

The surfacing module of claim 7 wherein the lobing is longitudinally aligned with respect to the aperture and is located on the portion of the annular aperture opposite the edge of the section to which the annularly apertured structure is affixed.

Claim 10

Dependent Claim 27 words

The surfacing module of claim 8 wherein the module may be folded upon itself with all sections in vertical alignment and each being supported by said lobing.

Claim 11

Dependent Claim 71 words

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.

Claim 12

Dependent Claim 71 words

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.

Claim 13

Dependent Claim 29 words

The portable roadway of claim 10 further comprising a hinged coupling means having an attached exterior shape that is lobed at the opposing longitudinal edges of the planar sections.

Claim 14

Dependent Claim 32 words

The portable roadway of claim 11 wherein the planar sections thereof may be folded upon themselves with all sections folding in a vertical alignment and each section being supported by said lobbing.

Claim 15

Dependent Claim 19 words

The portable roadway of claim 10 wherein the hinged coupling means comprises at least two hinges between each section.
