Most muscular replicator/multiflexer
One embodiment of an exercise device for the chest wherein to a base two large rotating sheaves are placed in a horizontal plane, turned by poles in the vertical plane to which rotating handles are attached. A cord attached to a pulley wraps around each sheave as the poles are rotated from a position of from behind the back to in front of the chest of the exerciser (or vice versa). The sheaves are placed in horizontal planes above or below the exerciser. Thus two functions of the chest, transverse adduction and medial rotation of the arms are multiplexed into one movement.

BACKGROUND1. Field Of Invention
This invention relates to exercise machines, specifically to pectoral muscle developers.
2. Prior Art
Although the pectorals represent the third largest muscle group in the body behind the legs and back, it is one of the hardest to reach when exercising. The following exercises represent the current state of the art in developing the chest: the bench press and pushups, the cable crossover machine, cable and dumbbell flyes, dips and the pec deck. Each is deficient in some regard.
In the bench press, the pectoral muscles are called upon only in the very beginning of the movement, as the humerus is drawn forward. The shoulder muscles and triceps soon take over and the pectorals are no longer involved. Many people frustrated with their lack of progress in developing the chest resort to using too much weight in the bench press and as a result hurt their shoulders. All the limitations of the bench press apply to pushups and dips as well.
The cable crossover machine provides resistance over the full course of the exercise movement but is effective only in the vertical plane. There is no resistance in response to any horizontal movement, thereby excluding many chest muscle fibers.
In cable and dumbbell flyes sideways resistance and pectoral involvement diminish as the arms move upward and the direction of the opposing force points downward (although this effect is lessened when a cable is used).
The pec deck provides resistance throughout as the arms are adducted transversely, yet does not account for the full range of pectoral involvement in moving the arms.
The “Gyrotonic” exerciser was designed to work the arms, and cannot be modified to work the chest in the manner of the “Most Muscular Replicator/Multiflexer.” The reasons why are discussed in the “Description of Invention” section under “Advantages.”
SUMMARYThe arsenal of chest building equipment today is incomplete, comparable to the dilemma that faced Arnold Schwartzenegger when it came to building arms. He realized that all of his biceps muscle fibers were not being called upon in performing the barbell curl because the biceps not only flex the elbow but supinate the forearm. His innovation was to supinate the forearm as he curled with a dumbbell, with stupendous results. Likewise, the pectoral muscles not only adduct the arms transversely, but also rotate the arms medially. The fusion of these two functions into one movement is accomplished uniquely by this embodiment of the “Most Muscular Replicator/Multiflexer.”
In accordance with one embodiment of my invention, two grooved wheels of sufficient circumference to take up an effective length of slack are placed in a horizontal plane, turned by variable-height poles to which rotating handles are attached. The position of the handles are horizontally adjustable. A cord attached to a pulley wraps around each wheel as the poles are moved from a position from behind the back to in front of the exerciser. The pulleys raise a sled holding weights along a vertical track. In one embodiment, a platform with two slots to accommodate the movement of the poles is fitted over the wheels to support the exerciser. The planetary motion thus formed in negative and positive opposition to the resistance of the weights isolates the chest and seamlessly engages it in medial rotation and transverse adduction. Note too that by simply turning around the exerciser can reverse the direction of the resistance.
DRAWINGS FiguresThe following is a brief description of the drawings:
Physical Structure
Referring to
The poles 26 are fitted into grooved wheels 30 and secured with a bolt (best shown in
Operation—
An exerciser stands on platform 20 between two slots and against a back brace 22,23 which may be aligned towards either the front or back of the machine to reverse the direction of positive and negative resistance. The cushioned support is adjusted in both horizontal and vertical planes as desired. A belt may be easily looped over the cushioned support for additional optional restraint. The arms are medially rotated as far behind the back as is comfortable and the rotating handles 24 are grasped (one at a time if necessary). The rotating handles 24 keep the hands and arms from being twisted (while at the same time allowing for supination and pronation of the arm if desired) and transfer force to the pole assembly 26,28. By adjusting the horizontal distance of the handle 24 to the pole 26,28, the leverage may be changed. The poles 28 turn the grooved wheels 30 around which a cord connected by a pulley 33 to a weight sled 34 is wound. The sled 34 elevates along a track comprised by welded pulley frame 36. As the handles are brought together by positive resistance, they are slowly returned to the starting position employing negative resistance.
ADVANTAGESThrough this embodiment two major functions of the pectoral muscle, transverse adduction and medial rotation, are seamlessly combined into one movement. A unique full circle of sustained resistance is brought to bear on the pectorals.

Operation—
An exerciser adjusts the desired height and depth of the cushioned support 23 to the back brace stanchion 22. From behind his back, the exerciser grasps the rotating handles B 54 that have been adjusted in the proper horizontal and vertical planes to the overhead poles 52, one at a time if necessary. The revolving handles 54 turn the poles 52 that rotate the overhead wheels 50 around which cords attached through pulleys to a weight sled 34 wind.
CONCLUSION, RAMIFICATION AND SCOPEThus the reader will see that in at least two embodiments of the “Most Muscular Replicator/Multiflexer” chest exerciser that the chest is isolated and worked to a highly efficient degree.
While my above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of two preferred embodiments thereof. Many other variations are possible. For example in the second embodiment
Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents
Claims
