Claims
- 1. A pathway enabling transit of a four-wheeled wheelchair along a route over an uneven terrain surface formed from matter that is resistant to the rolling traction of the wheelchair, comprising a pair of longitudinally extended flexible pathways traversing the route, each having a width capable of receiving thereon the front and side wheels at one side of the wheelchair, said paths being essentially parallel to and separated apart from each other a sufficient lateral distance such that the pathways are capable of separately receiving the front and rear side wheels on each opposite side of the wheelchair, said pathways being formed from a material that is relatively porous with respect to matter forming the terrain surface said pathways being further connected and maintained the predetermined distance apart by spacer sections at longitudinal distance intervals along the route.
- 2. The pathway of claim 1 in which the separation distance between the paths forms an opening permitting access to a footpath in the terrain surface for an assistant who assists the person in the wheelchair over the route in the terrain defined by the pathway.
- 3. The pathway of claim 1, including an upwardly extending side curb extending from a longitudinal edge thereof.
- 4. The pathway of claim 1 anchored at a terminal, longitudinal end section thereof to a fixed support in the terrain environment.
- 5. The pathway of claim 1 formed from a flexible material capable of being wound into a roll when not extended over the terrain.
- 6. The pathway of claim 5 comprising a longitudinally extended flexible mat material sufficient in length to extend from Point A to Point B such that a route between the two points is formed when the material is unrolled over the terrain.
- 7. The pathway of claim 5 formed from a metal chain link material.
- 8. The pathway of claim 5 formed from a wire mesh material.
- 9. The pathway of claim 5 formed from a flexible material including therein a plurality of holes in a perforated configuration.
- 10. The pathway of claim 1 including a plurality of holes in the material which permit the pathways to be conformable to the terrain surface and which allow matter of the terrain surface to migrate therethrough.
- 11. The pathway of claim 10 in which the holes are substantially curvilinear.
- 12. The pathway of claim 10 in which the holes are formed in a grid-like pattern.
- 13. The pathway of claim 10 in which the holes are multi-sided.
- 14. The pathway of claim 10 in which the aggregate area of the holes is from approximately 20% to approximately 80% of the surface area otherwise defined by the material of the pathway.
- 15. The pathway of claim 1 formed from a material including a flexible polymer.
- 16. The pathway of claim 15 formed from a UV resistant polymer.
- 17. The pathway of claim 1 formed from a material comprising a fiber composition.
- 18. The pathway of claim 1 in combination with a destination pod to which the route leads, the pod being at a location on the terrain distant from the beginning point of the route, the destination pod comprising an extended wheelchair tractionable surface on the terrain sufficiently large to allow positional movement of a wheelchair.
- 19. The pathway of claim 1 in which the pathways are formed from a mat material including a plurality of nibs downwardly projecting toward the terrain surface from the lower surface of the mat material along an extended length and width of the material and with respect to which, the matter of the terrain surface migrates upwardly to the lower surface of the mat material.
- 20. The pathway of claim 19 in which the mat includes a plurality of openings in a pattern in the surface thereof.
