Abstract

An exercise apparatus to simulate climbing is described that includes such features as arm handles that move in synchronism with the motion of foot pedals to provide a total body workout; side handrails; a mounting step; linear foot movement at a simulated climbing angle; a three point support structure using a vertical support column; pedal track covers; a mechanism to provide constant resistance to pedal motion; and pedal impact absorption.

Claims

1. An exercise apparatus comprising:

a frame adapted for placement on a horizontal surface;

a first substantially linear track secured to said frame;

a second substantially linear track secured to said frame in parallel with said first track wherein said first and second tracks are secured to said frame at an incline from said horizontal surface;

a first and a second foot pedal assembly, each including a foot pedal, wherein said foot pedal assemblies are engaged with said first and second tracks respectively for movement along said tracks such that said foot pedals move substantially linearly along and in parallel with said tracks; and

a load mechanism, operatively connected to said first pedal assembly and said second pedal assembly, including a transmission operatively connected with said first and second foot pedal assemblies and a resistance device operatively connected to said transmission effective to provide a constant resistance to the downward movement of said first and second pedals independent of the speed of said pedal assemblies;

wherein a connection mechanism connects said first pedal assembly to said second pedal assembly and to said transmission;

wherein said connection mechanism includes a first flexible member attached to said first and said second pedal assemblies and to said transmission; and

wherein said connection mechanism includes a second flexible member connecting said first pedal assembly to said second pedal assembly with said second flexible member engaged with said frame effective to cause said first pedal assembly to move downwardly along said first track when said second pedal assembly is moved upwardly along said second track.

2. The apparatus of claim 1 wherein said transmission includes a first and a second oneway clutch each rotatably secured to said frame and engaged with said first flexible member.

3. The apparatus of claim 2 wherein said first connection mechanism includes an idler pulley secured for rotation on said frame and said first flexible member is engaged with said idler pulley intermediate its engagement with said first oneway clutch and said second oneway clutch.

4. The apparatus of claim 1 wherein said second flexible member is engaged with an idler pulley secured for rotation on said frame.

5. The apparatus of claim 1 including a control mechanism operatively connected to said resistance device effective to vary said resistance to the downward movement of said first and second pedals in order to maintain a constant speed of said movement of said pedals.

6. The apparatus of claim 5 wherein said resistance device is an alternator and said control mechanism provides a load signal to said alternator effective to vary the output of said alternator to maintain a constant pedal speed.

7. The apparatus of claim 1 wherein said incline is approximately 30 degrees.
