Abstract

An exercise machine utilizing a dynamically controlled resistance technique. The machine employs two pivoting torque arms. Movement of a first torque arm is initiated by a user while performing an exercise routine. A strap and pulley system is utilized to guide a mobile member along the second torque arm to change the resistance perceived by the user. Weights can be added to the mobile member to further increase the perceived resistance. Hand levers are positioned to be operated by the user, which levers function to effect the movement of the mobile unit at any instant during the exercise routine.

Claims

1. A dynamically controlled resistance exercise machine, comprising:

a frame;

a torque arm, said torque mounted for pivotal movement and mechanically linked to said frame;

a mobile housing mounted for sliding movement on said torque arm;

first and second hand controlled levers for controlling the movement of said mobile housing on said torque arm;

first and second control lines extending from said first and second hand control levers; and

an array of guide rods and pulley belts mounted on said torque arm, wherein said first and second control lines are attached to said guide rods.

2. The dynamically controlled resistance exercise machine as recited in claim 1, wherein said guide rods are mounted for rotational movement.

3. The dynamically controlled resistance exercise machine as recited in claim 1, including an array of sprockets mounted on said guide rods.

4. The dynamically controlled resistance exercise machine as recited in claim 1, including a plurality of pegs mounted on said torque arm.

5. The dynamically controlled resistance exercise machine as recited in claim 1, further including an auxiliary torque arm, said auxiliary torque arm being mounted at one end for pivotal movement and including means for linking it to said torque arm, said auxiliary torque arm further including means for mechanically linking the second end to said frame, said auxiliary torque arm further being further linked to said first and second hand controlled levers for controlling the movement of said auxiliary torque arm, whereby movement of said auxiliary torque arm interacts with said torque arm and said mobile housing.

6. A dynamically controlled resistance exercise machine, comprising:

a frame;

a first torque arm, said first torque arm mounted for pivotal movement and mechanically linked to said frame;

a second torque arm, said second torque arm pivotally mounted to said first torque arm;

a mobile housing mounted for sliding movement on said second torque arm;

first and second hand controlled levers for controlling the movement of said mobile housing on said torque arm;

first and second control lines extending from said first and second hand control levers; and

an array of guide rods and pulley belts mounted on said second torque arm, wherein said first and second control lines are attached to said guide rods.

9. A dynamically controlled resistance exercise machine as recited in claim 6, including a plurality of pegs mounted on said second torque arm.

10. The dynamically controlled resistance exercise machine as recited in claim 6, wherein said first torque arm is mounted at one end for pivotal movement and including means for linking it to said second torque arm, said first torque arm further including means for mechanically linking the second end to said frame, said first torque arm being further linked to said first and second hand controlled levers for controlling the movement of said first torque arm, whereby movement of said first torque arm interacts with said second torque arm and said mobile housing.

7. The dynamically controlled resistance exercise machine as recited in 6, wherein said guide rods are mounted for rotational movement.

8. A dynamically controlled resistance exercise machine as recited in claim 7, including an array of sprockets mounted on said guide rods.

11. A dynamically controlled resistance exercise machine, comprising:

a frame;

a bench mounted on said frame

a first torque arm, said first torque arm mounted for pivotal movement and mechanically linked to said frame;

a second torque arm, said second torque arm pivotally mounted to said first torque arm;

a mobile housing mounted for sliding movement on said second torque arm;

first and second hand controlled levers mounted on said bench for controlling the movement of said mobile housing on said second torque arm;

first and second control lines extending from said first and second hand control levers; and

an array of guide rods and pulley belts mounted on said second torque arm, wherein said first and second control lines are attached to said guide rods.

12. The dynamically controlled resistance exercise machine as recited in claim 11, wherein said guide rods are mounted for rotational movement.

13. A dynamically controlled resistance exercise machine as recited in claim 11, including an array of sprockets mounted on said guide rods.

14. A dynamically controlled resistance exercise machine as recited in claim 11, including a plurality of pegs mounted on said second torque arm.

15. The dynamically controlled resistance exercise machine as recited in claim 11, wherein said first torque arm is mounted at one end for said pivotal movement and including means for linking it to said second torque arm, said first torque arm further including means for mechanically linking the second end to said frame, said first torque arm being further linked to said first and second hand controlled levers for controlling the movement of said first torque arm, whereby movement of said first torque arm interacts with said second torque arm and said mobile housing.
