Counter-gravity chin up and all body exercise machine

Abstract

A counter gravity exercise machine includes a frame, a seat beam for supporting a user, pivotally connected to the frame at a first pivot point on the frame, a link connected to the seat beam, wherein the link has an upper link end and a lower link end, an adjustment slider-slidingly connected to the seat beam and the link at the lower link end, wherein sliding user adjustment changes resistance via change in a mechanical advantage, a handle arm pivotally connected to the, link at a fourth pivot point and wherein the handle arm rotates and is rotably mounted on a second pivot, and an upright beam having an upper upright beam end and a lower upright beam end, wherein the lower upright beam end is connected to the frame and the upper upright beam end is connected to the second pivot point.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This application is entitled to the benefit of Provisional Patent Application No. 60 / 774,078 filed on Feb. 14, 2006.BACKGROUND OF THE INVENTION FIELD OF THE INVENTION [0002] This invention relates generally to fitness exercise machines for training upper body and lower body exercises utilizing the user's weight as a source of the resistance. [0003] Description of Related Art including information disclosed under 37 CFR 1.97 and 1.98 [0004] Potts, U.S. Pat. No. 4,846,458, discloses an upper body exercise apparatus to assist an exerciser to do chin-ups and dips. The apparatus includes a frame having a base, a platform parallel to the base for the exerciser to stand on, chin-up handles and dip handles extending from the frame, a system to oscillate the platform vertically between a lower position and an upper position while maintaining the platform parallel to the base and while avoiding any angular displacement, a pneumatic cylinder for ...

AI Technical Summary

Benefits of technology

"The present invention is an exercise machine that can be used for various upper and lower body exercises. It has a resistance adjustment to change the amount of resistance the user feels upon doing various exercises. The machine has a handle adjustment that changes the position of a handle arm to accommodate different body-size users and various exercises and their motion range. The machine also has a seat frame that is pivotally connected to the base frame at a first pivot point on the base frame, and a handle arm that is also pivotally connected to the base frame at a second pivot point on the base frame. The handle arm and the seat frame are linked such that when the handle arm is moved, the seat frame moves simultaneously. The link is pivotally connected to the handle arm and the seat frame at each end, making the resistance adjustment for adjusting the amount of resistance for various exercises. The machine is designed to make chin up and dip exercises safer than the existing machines by lowering the seat / knee pad to the ground and making the lowest position of the pad be the natural default position for the users to get on and off."

Problems solved by technology

While the pad may be lowered for the user to get on using the pneumatic control, the pneumatic system is costly and requires maintenance.

The machine uses weights to change the amount of the resistance, and multiple pads and their support frame require a complex structure.

This invention uses weights to assist the user, and the pad is positioned at its highest point of the range while the user is not on, an inconvenience and a danger.
