Abstract

An apparatus which serves as a physical exerciser and as a means of locomotion is built up of a chassis and at least two, but preferably three wheels, one of which is positively driven. The rider occupies a seat and actuates a linearly reciprocable drive member, the motion of which is transmitted to the driven wheel via a link, the linear movement being transformed into rotatory movement.

Claims

1. Physical exercise apparatus comprising a plural wheel vehicle having a chassis, at least one of the wheels being adapted to be positively driven, a stationary seat for a rider on the vehicle, two linearly reciprocable drive members on the vehicle forward of said seats, a link for transmitting the linear movement of each said drive member to the driven wheel while transforming said linear movement to rotatory movement of the driven wheel, and each of said linearly reciprocable drive members is provided at a different level on the vehicle.

2. The apparatus of claim 1 in which the vehicle is in the form of a tricycle having a forward wheel by which the vehicle may be steered and a pair of rearward wheels.

3. The apparatus of claim 1 in which the vehicle is four-wheeled and is provided with a pair of forward steerable wheels and a pair of rearward wheels.

4. The apparatus of claim 1 in which the vehicle is in the form of a tricycle provided with a pair of forward steerable wheels and a single rearward wheel.

5. The apparatus of claim 4 in which one of the rearward wheels is arranged to be positively driven.

6. The apparatus of claim 4 in which both rearward wheels are arranged to be positively driven.

7. The apparatus of claim 1 in which the chassis includes an upper rail and a lower rail of suitable cross-sectional configuration each defining a firm guidance, an endless chain slung about two spaced apart sprockets mounted at the ends of said rails, a movable member connected to said endless chain, said member being movable longitudinally with respect to one of the rails, means for transmitting the linear movement of the movable member to at least one of the wheels of the vehicle while transforming said linear movement to rotational movement of the driven wheel.

8. The apparatus of claim 7 in which the movable member disposed within the upper rail is provided with a transversely extending handle adapted for manual operation and the movable member associated with the lower rail is provided with pedals adapted for reciprocable linear movement through the agency of the rider'"'"'s feet.

9. The apparatus of claim 7 or 8 including at least one steerable wheel, the upper rail is tiltable about its longitudinal axis, mechanical means being provided for transferring such tilt to the at least one steerable wheel of the vehicle.

10. The apparatus of claims 7 or 8 in which the movable member disposed within the upper rail is connected to the chain through a bearing link to permit tilting of the movable member without affecting the orientation of the chain.

11. Physical exercise apparatus, as set forth in claim 1, wherein said two elongated rails comprise first rails, second rails mounted on said support member in a fixed manner below said first rails, a linear reciprocal drive member mounted on said second rails and being linearly reciprocal thereof, means connecting said drive member on said second rails to at least one of the wheels of said vehicle for transforming the linear movement of said drive member on said second rails into the rotational movement of said wheel, and pedals attached to said drive member on said second rails for moving said drive member in the linear reciprocating direction on said second rail, using the rider'"'"'s leg power.

12. Physical exercise apparatus, as set forth in claim 11, including means for combining the linear reciprocating movement of said drive member associated with said first rails and said drive members associated with said second rail so that the movement of said drive members can be transferred to at least certain wheels of said vehicle and at the same time said drive members can be operated independently of one another.

13. Physical exercise apparatus, as set forth in claim 11, wherein means for interrelating the linear reciprocating movements of said drive member associated with said first rails and said drive member associated with said second rail forcing said drive member associated with said second rail to move when the said drive member associated with said first rail is moved for use in forcibly displacing the legs of the rider while driving the apparatus.

14. Physical exercise apparatus, as set forth in claim 11, wherein said seat is located approximately at the level of said second rail, said being stationary seat includes a fixed back support against which the rider can rest his back.

15. Physical exercise apparatus, as set forth in claim 11, including braking means located on said support member adjacent said second rail for effecting braking of said vehicle, with pedals at any position along the rails without removing the feet from the pedals.

28. Physical exercise apparatus, as set forth in claim 11, including a pair of sprockets spaced apart mounted at both ends of the rails in the linear reciprocal direction, a chain trained around said sprockets, said drive member connected to said chain, said sprockets being rotatable in both directions, and said drive member being arranged to move freely along the full length of said rails.

29. Physical exercise apparatus, as set forth in claim 28, wherein said vehicle having a forward end away from the rider and a rearward end nearer the rider, said drive member being movable in the direction toward the forward end and toward the rearward end, and said sprocket closer to the rear end of said vehicle being capable of free rotation without the transmitting of movement when said drive member moves in the rearward direction.

16. Physical exercise apparatus capable of being driven while steered and of being braked while steered comprising a plural wheel vehicle including a support member having a seat thereon for a rider of the vehicle, a linearly reciprocal drive member mounted on said support member, two transversely extending handle bars cantilevered outwardly from and extending transversely of the linear reciprocal direction of said drive member, said support member including at least two elongated rails extending in the linear reciprocal direction for supporting and guiding said drive member in the linear reciprocal direction, said rails mounted on said support member at a height corresponding approximately to the driver'"'"'s shoulders, said rails being in parallel relation, and a bearing supporting each of the opposite ends of said rails and said rails being rotatable supported in said bearings for rotating about an axis extending through and between said bearings.

17. Physical exercise apparatus, as set forth in claim 16, said handle bars being arranged to be tilted by the rider'"'"'s hands and, in turn, to tilt said rails, and a steering mechanism for at least one of said wheels via a mechanical linkage interconnecting said guide rails and said steering mechanism for steering said vehicle.

18. Physical exercise apparatus, as set forth in claim 17, including a pair of sprockets spaced apart in the linear reciprocal direction, a chain trained around said sprockets, said drive member connected to said chain, said sprockets being rotatable in both directions, and said drive member being arranged to move freely along the full length of said rails.

19. Physical exercise apparatus, as set forth in claim 18, wherein said vehicle having a forward end and a rearward end, said drive member being movable in the direction toward the forward end and toward the rearward end, and said sprocket closer to the rear end of said vehicle being capable of free rotation without the transmission of movement when said drive member moves in the forward direction.

20. Physical exercise apparatus, as set forth in claim 19, including a bearing for connecting said drive member to said chain for enabling the tilting of said drive member without affecting the orientation of said chain.

21. Physical exercise apparatus, as set forth in claim 16, wherein said handle bars can be pushed and pulled in the linear reciprocal direction and can independently be tilted perpendicularly to the linear reciprocal direction at the same time, where both movements does not affect each other.

22. Physical exercise apparatus, as set forth in claim 16, including braking means located on said support member adjacent said elongated rail and associated with said handle bars so that the braking of said vehicle can be effected by the rider while holding said handle bars, at any position of the handle along the rails.
