Abstract
An exercising device which employ the principle of isotonic exercise in conjunction with isometric impact exercise. The exercising device comprises two spaced apart pivotably mounted levers to which the exerciser applies a rotational force; an adjustable resilient force, such as a spring, selectively opposing the rotation of the levers. The resisting force varies during the pivoting of the levers such that as the levers pass dead center the force applied by an exerciser reaches a maximum value and after passing dead center thereby permitting the levers to be rapidly rotated by the resisting force; and a lever stopping member for suddenly stopping the rapidly rotating lever.
Claims8
An exercising and development apparatus for use with the limbs of an exerciser employing the principle of isotonic exercise combined with the principle of isometric impact exercise comprising:
- a frame;
- a force resisting means;
- a first lever means being pivotably mounted on said frame and supporting said force resisting means;
- a second lever means pivotally mounted on said frame at a point spaced apart from the pivot point of the first lever means;
- means connecting the second lever means to said force resisting means, said first and second lever means being pivoted on the frame by the exertion of forces by a first limb of the exerciser on said first lever means and a second limb of the exerciser on said second lever means, said force resisting means offering a varying resistance during the pivoting of said first and second lever means by the exerciser such that as said first and second lever reach dead-center the force on the force resisting means reaches a maximum value, the pivoting of the lever means providing the limbs of the exerciser with isotonic exercise;
- and
- restricting means for limiting the pivoting of said first and second lever means, the force resisting means after said first and second lever means have passed dead center, then free to exert force against said first and second lever means impacting said lever means against said limiting means so as to apply to the limbs of the exerciser isometric impact exercise.
