Abstract

An exerciser provides low impact exercise for the upper and lower body of an operator. The apparatus includes an upper portion having moving rungs simulating a hand-over-hand motion to exercise one'"'"'s upper body and a lower portion having moving platforms simulating a stair-like climbing motion to exercise one'"'"'s lower body. The upper and lower portions are oriented at different angles to maximize user comfort, the angle of the lower portion in particular providing clearance for one'"'"'s knees during use. The exerciser also includes a variable speed control to adjustable vary the speed of the moving rungs and platforms, thereby adapting to the needs of various users.

Claims

1. An exerciser comprising:

a first mechanism for exercising the upper body of an operator, said first mechanism including hand support means which move in a first path for, simulating a hand-over-hand motion;

a second mechanism rigidly connected to said first mechanism for exercising the lower body of the operator, said second mechanism including foot support means which move in a second path for simulating a stair-like climbing motion; and

means for powering said first and second mechanisms.

2. The apparatus as defined by claim 1 wherein said second path is different than said first path.

3. The apparatus as defined by claim 2 wherein said second path is at a lower angle from horizontal than said first path.

4. The apparatus as defined by claim 1 wherein said means for powering includes a speed adjustment means for varying the speed of said hand support means and said foot support means.

5. The apparatus as defined by claim 4 including a friction clutch means for preventing the weight of an operator from increasing the speed of said means for powering beyond a predetermined rate.

6. The apparatus as defined by claim 4 including a programmable means for controllably presetting multiple speeds of said hand support means and said foot support means, and time durations for each speed.

7. The apparatus as defined by claim 5 wherein said hand support means includes rungs and wherein said foot support means includes platforms.

8. The apparatus as defined by claim 1 including a friction clutch means for preventing the weight of a person from increasing the speed of said first and second mechanisms beyond a predetermined rate.

9. The apparatus as defined by claim 1 including a programmable means for controllably presetting multiple speeds of said hand support means and said foot support means, and time durations for each speed.

10. The apparatus as defined by claim 1 wherein the angle of said first path from horizontal is between about 60°

to 75°

.

11. The apparatus as defined by claim 1 wherein the angle of said second path from horizontal is between about 45°

to 60°

.

12. The apparatus as defined by claim 1 wherein said foot support means includes multiple platforms.

13. The apparatus as defined by claim 12 wherein said second mechanism includes a pair of endless chains attached to the ends of each of said multiple platforms, and further includes a pair of axle means defining an upper and lower axis of rotation for movably carrying said endless chains, the lower of said axle means including a split shaft.

14. The apparatus as defined by claim 1 including a sheet of flexible material fastened to each of said foot support means so that said flexible material drapingly extends between successive parts of said foot support means.

15. The apparatus as defined by claim 1 wherein said hand support means includes multiple rungs and wherein said foot support means includes multiple platforms.

16. The apparatus as defined by claim 15 wherein said first mechanism includes a first pair of endless chains attached to the ends of each of said rungs for carrying said rungs along said first path and wherein said second mechanism includes a second pair of endless chains attached to the ends of each of said platforms for carrying said platforms along said second path.

17. The apparatus as defined by claim 1 including a photocell positioned to shine a beam across a lower portion of one of said paths and including means for detecting interruption of said beam, said photocell operably connected to stop said first and second mechanisms.

18. The apparatus as defined by claim 1 wherein said first and second mechanisms are pivotally interconnected between a folded position for shipping and an upright position for use.

19. An exerciser comprising:

a first portion for exercising the upper body of an operator including hand support members which move in a first path at a first angle from horizontal for simulating a hand-over-hand motion;

a second portion rigidly connected to said first portion for exercising the lower body of ) an operator including foot support members which move in a second path at a second angle from horizontal for simulating stair-like climbing motion, said second angle being different than said first angle; and

means for powering said first and second mechanisms.

20. The apparatus as defined by claim 19 wherein said first angle is between about 60°

and 75°
