Abstract
A multiple exercise unit capable of providing a user with a wide range of strength and conditioning exercises. The exercise unit provides resistance through an isokinetic device which utilizes a clutch mechanism. Lines extend out of the isokinetic device and attach to various exercise elements such that a variety of upper and lower body strength exercises may be performed.
Claims21
An exercise apparatus comprising:
- (a) a positionable bench;
- (b) a horizontal member extending below said bench;
- (c) a vertical member extending upwardly from a first end of said horizontal member;
- (d) a loading device operable to apply a drag on a moveable element forming part of the loading device, said loading device situated on said horizontal or vertical member, said loading device comprising a rotatable centrifugal force sensitive force generating brake member that provides a resistive force proportional to the speed of rotation of the rotatable member, said loading device comprising a housing having sidewalls that define an interior cylindrical contact surface and function as a brake drum, a braking rotor rotatably mounted within said housing and coaxially aligned relative to said interior cylindrical contact surface, at least one brake shoe pivotally mounted on said braking rotor, at least one brake pad secured to said at least one brake shoe and having an exterior cylindrical contact surface configured to mate with said interior cylindrical contact surface;
- (e) an exercise operable element connected to said loading device by a flexible line means, said exercise operable element being mounted such that upon movement of said exercise element, said line means is pulled away from said loading device, said moveable element of said loading device is moved and said line means is loaded;
- and
- (f) a line extending means outside said loading device for multiplying the rate at which said line means is pulled away from said loading device, wherein said line means extends through said line extending means.

- (c) a vertical member extending upwardly from a first end of said horizontal member;
- (d) a loading device operable to apply a drag on a moveable element forming part of the loading device, said loading device situated on said horizontal or vertical member, said loading device comprising a rotatable centrifugal force sensitive force generating brake member that provides a resistive force proportional to the speed of rotation of the rotatable member, said loading comprising a housing having sidewalls that define an interior cylindrical contact surface and function as a brake drum, a braking rotor rotatably mounted within said housing and coaxially aligned relative to said interior cylindrical contact surface, at least one brake shoe pivotally mounted on said braking rotor, at least one brake pad secured to said at least one brake shoe and having an exterior cylindrical contact surface configured to mate with said interior cylindrical contact surface;
- (e) an exercise operable element configured so it is suitable for grasping and displacing in a vertical direction, said exercise element extending over said bench and comprising a slidable carriage, said carriage having said line means secured thereto, said carriage configured such that it slides in an essentially vertical plane on said vertical member
- (f) a line extending means outside said loading device for multiplying the rate at which said line means is pulled away from said loading device, wherein said line means extends through said line extending means;
- and
- (g) an exercise operable element having an L-shaped configuration with a middle portion of said L-shaped configuration being pivotably attached to a vertically extending member attached to a second end of said horizontal member.
