Abstract

A lower support frame (A) mounts a lower body support structure (B) and an upper body exercise structure (C) thereon. The upper body exercise structure includes an upper frame (30) which is selectively and adjustably mounted on the lower support frame. A flywheel (40) is rotatably mounted in the upper frame. A belt (52) and selectable number of weights (62) drag along the flywheel for selectively adjusting the effort required to maintain rotation of the flywheel. Flexible cables (70, 72) are each wrapped around a pulley (84). A one-way clutch (86) selectively connects the pulley with the flywheel for providing rotational driving force thereto as the cable is pulled. A rewind spring (92) rewinds the cable back onto the pulley. The relative positions of the lower body support structure (B) and the upper body exercise structure (C) are selectively adjustable such that the exercise apparatus is usable in training for walking or running (FIG. 1), ski poleing (FIG. 4), canoeing or kayaking (FIG. 5), rowing (FIG. 6), and other sports.

Claims

1. An exercise apparatus comprising:

(a) a lower support frame including an upstanding frame portion extending upward to at least about the height of an athlete'"'"'s waist;

(b) a lower body support structure operatively connected with the lower support frame, the lower body support structure including;

(i) a lower support assembly supported on the lower support frame;

(ii) a longitudinally extending rail mounted horizontally on the lower support assembly and extending parallel to a floor on which the exercise apparatus is disposed;

(iii) an athlete supporting seat mounted to the support rail to be selectively and fixedly positioned therealong;

(iv) a telescopic member pivotally connected at one end with the longitudinally extending rail;

(v) a foot supporting structure connected with an other end of the telescopic member such that telescopic member adjusts a distance between the foot supporting structure and the longitudinally extending rail;

(vi) an angular adjustment mechanism for selectively fixing a relative angular relationship between the telescopic member and the longitudinally extending rail;

(c) an upper frame;

(d) a flywheel rotatably mounted adjacent a top of the upper frame;

(e) an adjustable drag means for selectively adjusting the effort required to maintain rotation of the flywheel;

(f) a drive means for selectively rotating the flywheel, the drive means being mounted contiguous to the flywheel;

(g) an adjustable mounting means for selectively mounting the upper frame to the lower support frame such that the flywheel and drive means are adjustably mounted above the athlete'"'"'s head;

(h) flexible cables extending downward from the drive means to at least one handle such that pulling the cables downward and rearward with effort as determined by the adjustable drag means causes the drive means to rotate the flywheel.

2. The exercise structure as set forth in claim 1 wherein the lower body support structure includes exercise means for exercising the lower body in conjunction with exercise of the upper body.

3. The exercise apparatus as set forth in claim 1 wherein the drive means includes a first pulley about which a first of the flexible cables is wrapped and a second pulley about which a second of the flexible cables is wrapped, a first one-way clutch which is connected between the first pulley and the flywheel, and a second one-way clutch which is operatively connected between the second pulley and the flywheel, and wherein the handle is an elongated member connected with the first and second cables such that an athlete can move the elongated member in a manner analogous to rowing, canoeing, or kyacking.

4. The exercise apparatus as set forth in claim 1 further including an angular velocity measuring means for measuring the speed with which the flywheel is currently rotating, a work calculating means for calculating the current amount of work being expended from the measured flywheel speed and an indication of the amount of drag applied by the adjustable drag means.

5. The exercise apparatus as set forth in claim 4 further including an energy calculating means for calculating the total amount of energy expended since the beginning of an exercise session from the calculated current amounts of work and a display means for displaying an indication of at least one of the calculated amount of work and energy.

6. An exercise apparatus comprising:

(a) a lower support frame including;

(i) a pair of parallel lower support rails;

(ii) an upstanding frame portion extending upward from the lower support rails;

(b) a lower body support structure including;

(i) lower supports movably supported on the lower support rails to be selectively and fixedly positional therealong;

(ii) a longitudinally extending rail mounted above the lower supports and extending parallel to the lower support rails;

(iii) an athlete supporting seat mounted to the support rail to be selectively fixedly positioned therealong;

(iv) a telescopic member pivotally connected at one end with the longitudinally extending rail;

(v) a foot supporting structure connected with an other end of the telescopic member such that telescopic adjustment of the telescopic member adjusts a distance between the foot supporting structure and the longitudinally extending rail;

(vi) an angular adjustment mechanism for selectively fixing a relative angular relationship between the telescopic member and the longitudinally extending rail;

(c) an upper body exercise structure including;

(i) an upper frame selectively mounted on the lower support frame upstanding portion;

(ii) a flywheel rotatably mounted on the upper frame,

(iii) an adjustable drag means for selectively adjusting the effort required to maintain rotation of the flywheel;

(iv) a drive means for selectively rotating the flywheel;

(v) flexible cables extending from the drive means to at least one handle such that pulling the cables with effort as determined by the adjustable drag means causes the drive means to rotate the flywheel.

7. The exercise apparatus as set forth in claim 6 wherein the lower support frame includes an upper extending portion and wherein the upper frame includes a plurality of generally U-shaped recesses for selectively engaging the lower frame upper extending portion in any one of a plurality of height relationships, whereby the height of the upper body exercise structure and the relative angle at which the cables are pulled is selectively adjustable.

8. The exercise apparatus as set forth in claim 6 wherein the foot support structure includes a rounded surface for selectively receiving the athlete'"'"'s feet thereunder and foot receiving loops on an opposite surface thereof.

9. The exercise apparatus as set forth in claim 6 wherein the angular adjustment mechanism includes at least one arcuate member which extends from the longitudinally extending rail, the arcuate member having a plurality of apertures therein and the telescopic member having at least one aperture which is selectively positioned in alignment with one of the arcuate member apertures as the telescopic member is pivoted, and a pin means for selective insertion through aligned arcuate member and telescopic member apertures.

10. The exercise apparatus as set forth in claim 6 further including:

an angular velocity measuring means for measuring the speed with which the flywheel is rotating and generating a speed signal indicative of the measured speed;

a drag signal means for generating a drag signal indicative of the amount of drag applied by the adjustable drag means;

a work calculating means for calculating the current amount of work being expended from the speed signal and the drag signal; and

,

a display means for displaying the current calculated amount of work being expended.

11. The exercise apparatus as set forth in claim 10 further including a rewind spring operatively connected with the pulley for rewinding the cable thereonto.

12. The exercise apparatus as set forth in claim 11 wherein the rewind spring is a spiral coil spring having one end operatively connected with the pulley and the other end operatively connected with the frame.

13. The exercise apparatus as set forth in claim 12 further including a protection plate disposed between the frame and the spring for preventing injurious interaction therebetween.

14. The exercise apparatus as set forth in claim 10 wherein the pulley has a peripheral groove for receiving the cable therein and further including cable restraining means extending from the frame closely adjacent the periphery of the pulley to prevent the cable from jumping from the peripheral groove.
