Abstract
Abstract An access pathway is provided as a device that may be temporarily or portably deployed for wheelchair users accompanied by an assistant. The device, which is a pathway that may be carried by the user or provided at a site when required, is installed in cooperation with a pre-existing anchor at the site, and may be subject to temporary loan, such as from a central community service provider or a library. A convenient and inexpensive system is thus provided that achieves wheelchair access in many circumstances.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
139 words
A wheelchair access system comprising: a wheelchair pathway including an anchor device (8,9) at a predetermined position therein adapted to cooperate with an extraneous anchor means (19) thereby securing the pathway over a barrier of stairs within a community; at least one said anchor means (19) installed at a barrier of stairs, and wherein said anchor device (8,9) includes at least one anchor plate (8) having a common location with respect to each barrier of stairs for temporarily securing a wheelchair pathway over a barrier of stairs, wherein the barrier of stairs connects an upper level with a lower lever; and the anchor device comprising a connector (9) cooperating with the anchor plate (8) of the pathway, and said connector (9) further cooperating with said anchor means (19) which is at a predetermined location adjacent the barrier of stairs.
Claim 2
Dependent Claim
139 words
A wheelchair access system comprising: a wheelchair pathway including an anchor device (8,9) at a predetermined position therein adapted to cooperate with an extraneous anchor means (19) thereby securing the pathway over a barrier of stairs within a community; at least one said anchor means (19) installed at a barrier of stairs, and wherein said anchor device (8,9) includes at least one anchor plate (8) having a common location with respect to each barrier of stairs for temporarily securing a wheelchair pathway over a barrier of stairs, wherein the barrier of stairs connects an upper level with a lower lever; and the anchor device comprising a connector (9) cooperating with the anchor plate (8) of the pathway, and said connector (9) further cooperating with said anchor means (19) which is at a predetermined location adjacent the barrier of stairs.
