Abstract
Abstract An exercising machine and method is disclosed wherein a rigid body supporting platform is supported at one end at a level such that the supporting surface is inclined at an angle to the horizontal. The support is constituted by a U-shaped tubular frame member and a standard portion which is secured to the U-shaped frame member. The rigid body supporting platform has a notch at one end thereof through which the standard passes and means are provided for rotatably mounting the U-shaped frame member on the underside of the supporting platform. A pair of crank and pedal means are rotatably mounted such that a downward weight on the underside of the platform by the weight of the user urges the standard towards the user and the legs of the U-shaped member away from the weight to thereby stabilize the platform. A flexible non-extensible strap has a handle at one end and is adjustably connected to the standard so that the tendency of the user to slide downwardly due to gravity and due to exertion of pedaling on the pedals is opposed by the user exerting a force on the standard in a direction urged by the weight and to urge the user's body up the incline surfaces. Thus, both the upper torso of the user is isometrically exercised at the same time that the lower torso and legs are being exercised by pedaling activity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
An exercise machine comprising, in combination, a rigid body supporting platform, means for supporting one end of said platform at a level such that it is inclined at an angle to the horizontal, said means supporting said one end of said platform including a U-shaped tubular frame member having a horizontal bar and a pair of legs, a standard mounted on one end of said rigid body supporting platform, means securing said standard to said U-shaped frame member at an angle other than 180 degrees, a pair of crank and pedal means, hub means for rotatably mounting said pair of crank and pedal means on the end of said standard, and means rotatably mounting said horizontal bar of said U-shaped frame on the underside of said rigid supporting platform such that a downward weight on the upper side of said platform urges said standard toward the weight and the legs of said U-shaped member away from said weight.
Claim 2
Dependent Claim
158 words
An exercise machine comprising, in combination, a rigid body supporting platform, means for supporting one end of said platform at a level such that it is inclined at an angle to the horizontal, said means supporting said one end of said platform including a U-shaped tubular frame member having a horizontal bar and a pair of legs, a standard mounted on one end of said rigid body supporting platform, means securing said standard to said U-shaped frame member at an angle other than 180 degrees, a pair of crank and pedal means, hub means for rotatably mounting said pair of crank and pedal means on the end of said standard, and means rotatably mounting said horizontal bar of said U-shaped frame on the underside of said rigid supporting platform such that a downward weight on the upper side of said platform urges said standard toward the weight and the legs of said U-shaped member away from said weight.
Claim 3
Dependent Claim
80 words
The invention defined in claim 1, including a flexible non-extensible strap means connected at one end to the upper end of said standard proximate said hub, and a handle secured to the other end of said non-extensible strap to enable the user to exert a force on said standard in the direction urged by said weight and to urge said user's body up the inclined surface of said rigid body supporting platform while exercising with said crank and pedal means.
Claim 4
Dependent Claim
23 words
The invention defined in claim 1, including notch means formed in the end of said body supporting platform through which said standard passes.
Claim 5
Dependent Claim
17 words
The invention defined in claim 1, wherein said standard includes means for lockably adjusting the length thereof.
Claim 6
Dependent Claim
12 words
The invention defined in claim 1, wherein said angle is about 121/2°.
Claim 7
Independent Claim
103 words
A method of simultaneously exercising the upper and lower limbs and torso of the human body comprising, inclining said human body on an inclined platform so that the head of said human body is below the heart thereof, performing a pedaling exercise with the lower limbs and, simultaneously with said pedaling motion performing an isometric exercise between the arms and a point between the lower limbs and a point above said platform, said isometric exercise urging said human body up said inclined platform against the combined force of gravity and said pedaling exercise tending to slide said human body down said inclined platform.
Claim 8
Independent Claim
103 words
A method of simultaneously exercising the upper and lower limbs and torso of the human body comprising, inclining said human body on an inclined platform so that the head of said human body is below the heart thereof, performing a pedaling exercise with the lower limbs and, simultaneously with said pedaling motion performing an isometric exercise between the arms and a point between the lower limbs and a point above said platform, said isometric exercise urging said human body up said inclined platform against the combined force of gravity and said pedaling exercise tending to slide said human body down said inclined platform.
Claim 9
Dependent Claim
22 words
The method defined in claim 6 including adjusting the degree of exertion required to perform said pedaling exercise and said isometric exercise.
