Abstract

The vehicle has a support component which has two wheels and a frame work supporting a seat above and forward of the two wheels, a second steering component which has a wheel and means for steering the wheel and means disposed just above ground level for connecting the components so that a provisionally ambulatory medical patient who is either weak from disease or injury or who is partially crippled can mount the self-supporting vehicle and ride it from point to point without changing from a standing position.

Claims

1. A patient vehicle comprising a support component comprising two spaced wheels, a seat, and means for supporting said seat on said wheels;

a steering component comprising a wheel having steering means;

means connecting said components and defining a center line dividing said vehicle into right and left parts, said means having a portion offset to one side of the center line of the vehicle to allow clearance for the feet of the user;

said seat being positioned over the rear portion of said offset portion such that a patient may mount the seat without stepping over said offset portion.

2. The vehicle of claim 1 having means disposed on said steering component to prevent the turning of the wheel past a predetermined angle, to preserve the stability of the vehicle.

3. The vehicle of claim 2 wherein said means disposed on the steering component to prevent the turning of the wheel past a pre-determined angle comprises a pair of rearwardly extending spurs disposed to engage said means connecting said components.

4. The vehicle of claim 1 wherein said seat is adjustable.

5. The vehicle of claim 1 wherein said offset portion is disposed just above ground level.
