Claims
- 1. Apparatus for assisting transit of a person seated in a chair transport device in either direction between a lower level and an upper level including:
- a pair of separate spaced-apart longitudinally extended pathways having upper and lower ends disposed between the lower level and the upper level, each pathway having a width sufficient to accommodate a support on one side of a chair, in which the separation of the pathways is sufficient to provide an access path for at least one assistant who guides the chair with respect to the pathways, and in which each pathway includes at least one stop for maintaining the location of the chair at a predetermined location along the length of the pathways, the stop being at a location along the length of the pathways intermediate and spaced from the upper and lower ends thereof.
- 2. The apparatus of claim 1 in which the lower ends of the supports on each side of the chair include one of a sliding mechanism and a rolling mechanism.
- 3. The apparatus of claim 1 in which at least one of the pathways includes an upwardly extending curb section longitudinally included on at least one side edge thereof.
- 4. The apparatus of claim 1 in which the pathways are disposed such that the lower end of the pathway is elevated above the lower level and each pathway includes a first stop comprising an upwardly extending extension of the lower end.
- 5. The apparatus of claim 1 in which the stop comprises a shape that in its longitudinal cross-section is essentially triangular and protrudes above the extended pathways.
- 6. The apparatus of claim 1 in which the stop comprises an opening within the length of each pathway, the opening adapted to receive temporarily therein the lower end of a support on a side of the chair.
- 7. The apparatus of claim 6 in which the lower ends of the supports on each side of the chair include a wheel and in which the opening in the pathways is sufficiently wide to receive a segment of the wheel and extends a length within the pathways less than the diameter of the wheel.
- 8. The apparatus of claim 6 in which the lower ends of the supports on each side of the chair include a wheel and in which the opening in each pathway is sufficiently wide to receive the wheel and extends a length within the pathways greater than the diameter of each wheel and the pathway further includes a back plate forming with the opening a recess that receives the wheel.
- 9. The apparatus of claim 1 in which the chair includes one wheel at each side thereof.
- 10. The apparatus of claim 1 in which the chair includes two wheels at each side thereof.
- 11. The apparatus of claim 9 or claim 10 in which the wheels of the chair are adjustable in their separation distance to accommodate the separation distance of the side pathways.
- 12. The apparatus of claim 1 in which the stop is a pivoted retractable brake disposed along the length of the pathways.
- 13. The apparatus of claim 12 in which the brake is pivoted at a lower end.
- 14. The apparatus of claim 12 in which the brake is pivoted at the upper end.
- 15. The apparatus of claim 12 in which the brake is pivoted at an intermediate section of the pathways and spaced from the ends.
- 16. The apparatus of claim 12 or claim 13 or claim 14 or claim 15 in which the brake includes a spring in operative combination with the pivot to maintain the brake in a position such that the brake stops the movement of the chair on the pathways.
- 17. The apparatus of claim 12 or claim 13 or claim 14 or claim 15 in which the brake is in operative relationship with a means to retract the brake from its stop position.
- 18. The apparatus of claim 1 in which a rest stop is provided at an interval along the length of each pathway corresponding to approximately the length of each pathway that spans two to three steps.
- 19. The apparatus of claim 1 in which a rest stop is provided at the midpoint along the length of each pathway.
- 20. The apparatus of claim 1 in which each pathway is disposed at an angle greater than approximately 45.degree. with respect to a horizontal line at the lower level.
- 21. An access device for providing assistance in the transit between an upper level and a lower level of a person seated in a chair transport device, including:
- a chair transport device in which a person may be seated having a support on each side;
- a pair of separate spaced-apart longitudinally extended pathways having upper and lower ends disposed to allow passage between the upper level and the lower level, each pathway having a width sufficient to accommodate a support on one side of a chair, and in which the separation of the pathways is sufficient to provide an access path for at least one assistant who guides the chair with respect to the pathways, in which each pathway includes at least one rest stop for maintaining the location of the chair at a location along each length of the pathway, the rest stop being one of an opening in, recess within or protrusion from the surface of each pathway that is adapted to maintain the location of the chair at the rest stop, the stop being intermediate and spaced from the upper and lower ends thereof, and in which
- the chair includes a tilt that allows the chair to pivot with respect to the rest stop such that the support on the side of the chair is enabled to traverse thereover.
