Abstract
A walker for assisting physically challenged persons to move around. The walker comprises a frame with wheels mounted on it for traveling over a surface. Oxygen tank supports are mounted on the seat and are adapted to receive oxygen bottles therein. A counterbalance is mounted on the frame to counteract the weight of any oxygen bottles received in the tank supports and thereby maintain the stability and balance of the walker.
Claims20
A walker for assisting physically challenged persons to be mobile, the walker comprising:
- a frame having a front end and a rear end;
- wheels mounted on the frame to allow the walker to be moved over a surface;
- a first tank support mounted on the frame proximate the front end thereof and adapted to receive an oxygen bottle therein;
- wherein the first tank support comprises a pair of coaxially aligned, spaced apart first and second supports each adapted to engage an outer surface of an oxygen bottle, said first and second supports being connected together by a bar that is mounted on the frame by at least one clamping member;
- and wherein the clamping member includes;
- an arm;
- and
- a pair of plates mounted on said arm, the plates being movable toward each other to engage a portion of the frame of the walker;
- and the plates being movable away from each other to release said portion of the frame of the walker;
- and
- a counterbalance mounted on the frame proximate a rear end thereof and a spaced distance from the first tank support;
- whereby the stability of the walker during motion is enhanced.
