Abstract

Disclosed is a rowing machine (10) having two resistance mechanisms or flywheels (44, 49). The dual resistance is applied through the movable handle (19) and movable seat (12). The handle (19) is interconnected by means of a cord (28) to the first flywheel (44), and the seat (12) is interconnected by means of a cord (29) to the second flywheel (49). The seat (12) is mounted upon an inclined track (11) and is anatomically contoured. The resistance mechanisms (44, 49) are adjusted by means of drag straps (53, 54) and an adjuster (55). The inclination of the track (11) and the position of the foot plates (23) is adjustable.

Claims

1. An exercise apparatus, comprising:

(a) a seat slidably mounted upon an inclined track having a forward end and a rear end, the track being inclined at an angle;

(b) a first flywheel resistance means interconnected to a handle, wherein a user pulling upon said handle applies force against resistance of said first flywheel resistance means;

(c) a second flywheel resistance means interconnected to said seat, wherein a user pushing against a foot plate and said seat applies force against resistance of said second flywheel resistance means;

(d) means for adjusting the resistance of said first and second flywheel resistance means; and

(e) a support column, the support column being affixed to the track and extending between the track and a horizontal support surface, said support column being configured to support said handle, the support column further comprising;

(i) an inner member, the inner member having a first outer dimension, the inner member being formed so as to have a plurality of diametrically opposed orifices passing through the inner member;

(ii) an outer member, the outer member having a second inner dimension, the second inner dimension being greater than the first outer dimension, the outer member being formed so as to have a plurality of diametrically opposed orifices passing through the outer member, the inner member being slidably positionable within the outer member, the inner member being adjustably secured to the outer member by means of at least one shafted fastener passing through at least one pair of aligned orifices on the inner and outer members, thereby establishing a lengthwise dimension of the support column and the angle of inclination of the track;

2. The exercise apparatus according to claim 1, wherein said flywheel assemblies include one-way drive means.

3. The exercise apparatus according to claim 1, wherein said seat includes a rear support portion.

4. The exercise apparatus according to claim 1, further comprising friction brake means for fictionally restraining motion of said first and second flywheel assemblies.

5. The exercise apparatus according to claim 4, wherein said friction brake means comprises a dragstrap and said resistance adjustment means comprises a buckle attached to said dragstrap and slidably mounted upon a frame member of said exercise apparatus, wherein the position of said buckle controls a restraining force of said dragstrap.

6. The exercise apparatus according to claim 5, wherein said foot plate is mounted upon a support frame of said exercise apparatus and are pivotable, the position of said foot plates upon said support frame being adjustable.

7. The exercise apparatus according to claim 6, wherein said seat is elevated approximately one foot from floor level.

8. The exercise apparatus according to claim 7, wherein a shaft upon which said flywheel resistance means is mounted includes a torsional spring for biasing said apparatus toward a starting position.

9. A rowing machine exercise apparatus, comprising:

(a) a seat having a rear support portion, said seat being slidably mounted upon an inclined track having a forward end and a rear end, wherein said track is positioned at a level above floor level and a first and second foot plate is pivotably mounted below the level of said track such that each foot plate is able to swivel about a pivot point, the extent of the pivoting motion being adjustable;

(b) a first shaft member rotatably mounted on said frame, a first one-way clutch means, a first flywheel and a first torsional spring mounted on said shaft, said first flywheel being interconnected to a handle by means of a first cord;

(c) a second shaft member rotatably mounted on said frame, a second one-way clutch means, a second flywheel, and a torsional spring being mounted on said shaft, said second flywheel being interconnected to said seat by means of a second cord; and

(d) a support column, the support column being affixed to the track and extending between the track and a horizontal support surface, said support column being configured to support said handle, the support column further comprising;

(i) an inner member, the inner member having a first outer dimension, the inner member being formed so as to have a plurality of diametrically opposed orifices passing through the inner member;

(ii) an outer member, the outer member having a second inner dimension, the second inner dimension being greater than the first outer dimension, the outer member being formed so as to have a plurality of diametrically opposed orifices passing through the outer member, the inner member being slidably positionable within the outer member, the inner member being adjustably secured to the outer member by means of at least one shafted fastener passing through at least one pair of aligned orifices on the inner and outer members, thereby establishing a lengthwise dimension of the support column and the angle of inclination of the track; and

(e) resistance adjustment means for adjusting resistance of said first and second flywheels such that a person residing in the seat may engage in a reciprocating rowing motion, each foot plate being rotatable within present limits as the person moves back and forth along the inclined track.

10. An exercise apparatus, comprising:

(a) a seat slidably mounted upon an inclined track having a forward end and a rear end, the track being inclined at an angle;

(b) a first flywheel resistance means interconnected to a handle, wherein a user pulling upon said handle applies force against resistance of said first flywheel resistance means;

(c) a second resistance means interconnected to said seat, wherein a user pushing against a foot plate and said seat applies force against resistance of said second resistance means;

(d) means for adjusting the resistance of said first and second flywheel resistance means; and

(e) a support column, the support column being affixed to the track and extending between the track and horizontal support surface, said support column being configured to support said handle, the support column further comprising;

(i) an inner member, the inner member having a first outer dimension, the inner member being formed so as to have a plurality of diametrically opposed orifices passing through the inner member;

(ii) an outer member, the outer member having a second inner dimension, the second inner dimension being greater than the first outer dimension, the outer member being formed so as to have a plurality of diametrically opposed orifices passing through the outer member, the inner member being slidably positionable within the outer member, the inner member being adjustably secured to the outer member by means of at least one shafted fastener passing through at least one pair of aligned orifices on the inner and outer members, thereby establishing a lengthwise dimension of the support column and the angle of inclination of the track.
