Abstract

Hand-powered and controlled two-wheeled cycle for use of disabled persons having reduced leg functions. The cycle provides a rapid and efficient means of mobility for leg-disabled persons. A preferred embodiment comprises a cycle having a low rider position, hand-powered and controlled front-drive crank and variable gear propulsion means, braking means, and remotely controlled outrigger means.

Claims

1. A two-wheeled, hand-powered and hand-controlled cycle for leg disabled riders having a front wheel and a rear wheel arranged in the same vertical plane and axially in the same horizontal plane comprising:

(a) a rigid support frame having a low center of gravity;

(b) a combination manual steering and powering means for said front wheel of said cycle having hand cranks which extend one from each side of a transverse axles of said steering and powering means and which include handle end knobs which are aligned axially with each other permitting rotary power motion and steering;

(c) a retractable wheeled outrigger assembly;

(d) a seating means; and

(e) a rigid full leg support means for said rider comprising two bars extending from the seating means to its terminus where the feet of said rider rest whereby the seating means is supported by the two bars.

2. A cycle according to claim 1 wherein said retractable outrigger assembly has at least one outrigger wheel.

3. A cycle according to claim 2 wherein said outrigger assembly has two wheels.

4. A cycle according to claim 2 having a braking means and a brake control means.

5. A cycle according to claim 2 wherein said seating means and leg support means are positioned in a horizontal plane a height above the ground not exceeding the height of the horizontal plane of the axles of the front and rear wheels.

6. A cycle according to claim 4 wherein said powering means has adjustable multiple gear means.

7. A cycle according to claim 6 wherein said gear means

further comprises a large gear assembly on the combination steering and powering means and a smaller gear assembly on the hub of said front wheel.

8. A cycle according to claim 7 wherein said leg support means is adjustable.

9. A cycle according to claim 7 wherein said seating means is adjustable.

10. A cycle according to claim 6 wherein said leg support means supports a rider'"'"'s legs in essentially a horizontal position where said legs are parallel to one another.

11. A cycle according to claim 6 wherein said outrigger assembly has a remote control means which is hand activated.

12. A cycle according to claim 6 wherein said brake control means is located in juxtaposition to the combination steering and powering means and to the retractable outrigger assembly.

13. A cycle according to claim 6 wherein said brake means is affixed to one of the front wheel, the rear wheel, and both the front and rear wheels.

14. A cycle according to claim 5 wherein said seating means permits the leg disabled rider to ride in a recumbent position.

15. A cycle according to claim 8 wherein said adjustable leg support means is telescoping.

16. A cycle according to claim 7 wherein said gear means has 21 speeds.

17. A cycle according to claim 1 wherein said frame means is chrome molybdenum.

18. A two-wheeled, hand-powered and hand-controlled cycle for leg disabled riders having a front wheel and a rear wheel arranged in the same vertical plane and axially in the same horizontal plane comprising:

(a) a rigid support frame having a low center of gravity;

(b) a combination manual steering and powering means for said front wheel of said cycle having cranks which extend from the axle of said steering and powering means parallel to each other permitting rotary power motion and steering capability;

(c) a rigid full leg support and seating means comprising two telescoping parallel bars extending the length of the rider'"'"'s legs between the buttocks and the feet whereby a seat of the cycle is supported by said bars; and

(d) a retractable wheeled outrigger means.

19. A cycle according to claim 18 wherein said leg support and seating means is essentially positioned in the same or lower horizontal plane as the axles of the front and rear wheels.

20. A cycle according to claim 18 wherein said cycle has a breaking means and a brake control means, adjustable multiple gear means, and adjustable leg support and seating means.
