Most muscular replicator/multiflexer
Abstract
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.

FEDERALLY SPONSORED RESEARCH
[0002] Not applicable
SEQUENCE LISTING OR PROGRAM
[0003] Not applicable.
BACKGROUND
[0004] 1. Field Of Invention
[0005] This invention relates to exercise machines, specifically to
pectoral muscle developers.
[0006] 2. Prior Art
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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).
[0011] 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.
[0012] 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."
SUMMARY
[0013] The 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."
[0014] 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.

DETAILED DESCRIPTION OF FIRST EMBODIMENT
Physical Structure
[0028] Referring to FIG. 1, the first embodiment has a platform 20
on which an exerciser stands. I contemplate that the platform in
this embodiment is made of aluminum, but other materials are also
suitable. The platform has slots through which two pole assemblies
26,28 equipped with rotating handles 24 arise. Integrated into the
handles of this embodiment are ball bearings and beveled gears FIG.
6 that enable it to rotate. (Although in other embodiments ball
bearings alone are contemplated). Returning to FIG. 1, the sleeve
26 of pole 28 can telescope vertically and the rotating handle 24
attaches to the sleeve at variable horizontal lengths. The top of
the platform FIG. 1 is fitted with four holes through which bolts
secure a back brace 22 and 23 to face either forwards or backwards.
The back brace is comprised of a stanchion 22 and a cushioned
support 23. The stanchion 22 has holes along its lateral sides to
secure the cushioned support 23 at variable heights. The cushioned
support 23 has holes on its lateral extensions to attach it to the
stanchion 22 at variable depths. The platform 20 is fitted to rest
on frame bars 40 and 42 like a box top, with two holes on each side
and front flap through which bolts attach it to bars 40 and 42 of
the flame. Note that in this embodiment, the horizontal bars that
comprise the frame 31,38 and 42 and contemplated to be made of
steel have welded flanges through which bolts connect them to
lateral bars 40.
[0029] The poles 26 are fitted into grooved wheels 30 and secured
with a bolt (best shown in FIG. 4). Referring to FIGS. 1 and 2, the
wheels are upheld by support beam 31. Eyelets welded to the wheels
FIG. 4 anchor the cords on one end and a welded nut connects them
to a unitized weight sled 34 at the other. FIGS. 1 and 2 show that
this is mediated by two sets of pulleys 33, one of which rests on
rear frame bar 38 and the other perched on welded pulley frame 36
The welded pulley frame 36 fits over the rear frame bar 38 in a
sleeve construction that in this case locks it in place FIG. 5 with
the help of four bolts.
Operation--FIG. 1
[0030] 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.
ADVANTAGES
[0031] Through 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.
[0032] FIG. 11 is a prior art figure of the "Gyrotonic" exerciser
which uses radial motion applied to rotors to work the arms. The
"Gyrotonic" exerciser was designed to work the arms, and cannot be
modified to exercise the chest in the manner that the "Most
Muscular Replicator/Multiflexer" does. The reason for this is that
when the arm system of the "Gyrotonic" is placed in the horizontal
plane needed to facilitate both medial rotation and transverse
adduction FIG. 11, the radial extension 44 (Gyrotonic part number)
displaces the exerciser in the circle described by the path of the
handle. In the "Most Muscular Replicator/Multiflexer," the radial
element (the grooved wheel or sheave) is in a different plane from
the exerciser where it causes no obstruction. Thus with the "Most
Muscular Replicator/Multiflexer," the path of motion conforms to
the "wheelhouse" of the exerciser, while with the "Gyrotonic" the
arm would be compelled along an impossible track, imperiling the
rotator cuff. Also with the "Gyrotonic," the intercession of the
exerciser's body prevents communication of the handles at either
the top or the bottom of the movement.
DETAILED DESCRIPTION OF SECOND EMBODIMENT
Physical Structure
[0033] Referring to FIG. 7, the second embodiment is equipped with
a back brace 22, 23 that is attached to either anterior frame bar
43 or back brace support beam 44, depending on the direction of
negative or positive resistance that is desired. Anterior flame bar
43, back brace support beam 44 and posterior frame bar 45 are
attached with bolts through welded flanges to lateral frame bars
46. Longitudinal frame bars 56 fit over the sleeves of anterior
frame bar 43 and posterior flame bar 45 and are locked in place
with two bolts each The four longitudinal bars 56 in turn form
sleeves that the unitized top frame piece 48 fits into and is
locked into place with two bolts on each corner. Two long heavy
duty bolts pass through the notched shafts of the overhead pole 52
and the overhead wheels 50 and secure both to the crossbeam of the
unitized top frame piece 48. Two cords anchored by eyelets wrap
around the overhead wheels 50 as they rotate and elevate a weight
sled 34 along the track provided by the two rear longitudinal flame
bars 56. This is mediated by two pulleys 33 that perch on the
unitized top frame piece 48. Two rotating handles B 54 turn the
overhead poles 52.
Operation--FIG. 7
[0034] 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 SCOPE
[0035] Thus 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.
[0036] 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 FIGS. 7 and 8 the overhead pole 52
and the crossbeam of the unitized top frame piece 48 may be
designed with auxiliary parallel holes through which a safety chain
may be drawn. Or the flame may be designed in both the first and
second embodiments to support the grooved wheels 30,50 in bunk bed
fashion with corresponding horizontal and vertical elongations of
the poles 28, 52.
[0037] Accordingly, the scope of the invention should be determined
not by the embodiments illustrated, but by the appended claims and
their legal equivalents
