Abstract

The present invention relates to a low-impact, time-efficient way to exercise both the cardio-respiratory system and the muscular system, particularly the abdominal and back muscles. The exerciser uses his muscles to oscillate a pivoted carriage within a frame. In one embodiment, the exerciser pedals a crank to pump hydraulic fluid through a hydraulic circuit to a hydraulic cylinder connected between the carriage and the frame so as to urge the carriage to oscillate with respect to the frame. A limit sensor detects when the carriage is positioned at one extreme of its oscillation and signals the hydraulic circuit to reverse the flow of hydraulic fluid to the hydraulic cylinder.

Claims

1. An exercise apparatus comprising:

(a) a frame;

(b) a carriage, suspended from the frame for oscillatory motion relative thereto; and

(c) a motor, adapted to receive at least some of its required input energy in the form of human motion, connected to the frame and the carriage so as to urge the carriage to move relative to the frame, wherein the motor includes;

(i) an input transducer for receiving energy in the form of human motion;

(ii) an actuator having a cylinder with a piston and connected to the frame and the carriage so as to urge the carriage to move relative to the frame, wherein the cylinder is double-acting having;

I. an extension port; and

II. a retraction port,

whereby hydraulic fluid supplied to the extension port urges the piston to extend from the cylinder and hydraulic fluid supplied to the retraction port urges the piston to retract into the cylinder; and

(iii) a hydraulic pump connected to;

I. the input transducer to receive at least some of its required input energy therefrom; and

II. the cylinder to exchange hydraulic fluid therewith.

10. An apparatus as claimed in claim 1, wherein the motor includes a hydraulic circuit that connects the hydraulic pump to the extension port and the retraction port, the hydraulic circuit having:

(a) a first state in which the pump draws hydraulic fluid from the retraction port and supplies hydraulic fluid to the extension port, whereby the piston is urged to extend from the cylinder; and

(b) a second state in which the pump draws hydraulic fluid from the extension port and supplies hydraulic fluid to the retraction port, whereby the piston is urged to retract into the cylinder.

11. An apparatus as claimed in claim 10, wherein:

(a) the motor includes a limit sensor operable to generate a signal when the carriage is positioned at one extreme of its oscillation relative to the frame; and

(b) the hydraulic circuit is operable to change its state in response to the signal.

12. An apparatus as claimed in claim 11, wherein the hydraulic circuit provides mechanical advantage between the input transducer and the actuator.

13. An apparatus as claimed in claim 12, wherein the hydraulic circuit maintains the piston in its current position with respect to the cylinder when the motor stops receiving input energy in the form of human motion.

14. An apparatus as claimed in claim 12, wherein the hydraulic circuit allows the piston to slowly return to a rest position in the cylinder when the motor stops receiving input energy in the form of human motion.

15. An apparatus as claimed in claim 12, wherein the carriage includes at least one of:

(a) a harness adapted to secure a person;

(b) a seat;

(c) a platform adapted to support a person; and

(d) a handlebar.
