FRICTION TYPE EXERCISING DEVICE WITH SEPARATE HANDGRIP
EXERCISER
Abstract
An exercise apparatus includes a platform adapted to be mounted
by a person and rotate responsove to a twisting motion executed by
such person. An arm extends generally upward relative to the
platform and is disposed for being grasped by the person on the
platform. The platform and the arm undergo coordinated
counterrotating motion in response to the twisting motion, thus
providing muscle toning and exercise to a user. A latching device
is provided to latch the platform after it has reached its limit of
rotational excursion and to unlatch it in response to a manually
supplied force whereby to obtain additional exercise for hand and
arm muscles. A valve is provided to control the amount of fluid
passing from a resilient fluid type hand exerciser on the arm. The
apparatus has a structure for limiting the rotation of the arm and
the platform. The resilient hand exerciser may have a spring
substituted for the resilient fluid type hand exerciser, to require
the user to exert a larger twisting force to rotate the platform
against a friction brake.

Description
SUMMARY OF THE INVENTION
This invention refers to an exercise apparatus which is
particularly adapted for use by golfers, baseball pitchers and
other persons who wish to exercise their main body muscles and also
their arm and hand muscles. It has been recently stated by many
authorities that the most desirable exercise apparatus is one in
which many muscles of a person are in motion and are stressed for
extended periods of time. Typical of a preferred apparatus of this
type is, of course, the bicycle type exercising device which may be
an actual bicycle operated over a road or the stationary type
bicycle apparatus used in the home or in an exercise studio. The
bicycle type apparatus provides primarily exercise to the leg
muscles of an operator and while stimulating, on account of such
exercise, the heart muscle to produce increased blood flow, there
are other muscles in the human body which are not to any measurable
extent in use with this type of device.
The present exercise apparatus is one which provides a different
type of exercise by requiring a person to execute a twisting
motion, such as is required during pitching a ball or playing golf.
To this end, the apparatus disclosed hereafer comprises a platform
adapted to undergo limited rotational excursion in response to a
person disposed on the platform executing a twisting motion. An arm
extending forwardly from the platform is grasped by the person and
responsive to the motion of the platform, the arm is urged into
counterrotation, thus providing an exercise which sould greatly
contribute to the loosening of body muscles and subjecting the body
and arm of the user to a rapid and forceful motion inherent in the
aforementioned sports. Furthermore, the present apparatus is
designed with a means for strengthening the hand and arm muscles of
the user by providing a hand grip to be squeezed cyclically during
such exercise.
The above described features and objectives are obtained in a very
simple and expedient manner. There is no requirement for electric
motors or driven parts. In this manner the present invention
discloses a most versatile and useful exercise apparatus which has
wide application not only among persons interested in physical
fitness, but also among persons engaging in various sports such as
golf, baseball, basketball and the like. The broad principle of the
present invention together with a preferred embodiment thereof will
be more clearly apparent from the following description when taken
in conjunction with the accompanying drawing.

DETAILED DESCRIPTION
Referring now to the figures and FIGS. 1, 2 and 3 in particular,
the exercise apparatus is designed so that a person standing or in
knee bent position on the rotatably mounted platform 10 grasps with
one or both hands the handle bar 12 or the vertical extension 14 of
an arm 15. Responsive to the person executing a body twisting
motion, the platform is caused to rotate in one direction, such as
is indicated by the arrow A, FIG. 1, while the arm 15 is caused to
undergo a coordinated counterrotation, see arrow B. As illustrated
in FIG. 1, the arm 15 is in its central position, but it will be
understood from the description hereinafter that the platform 10
and arm 15 are adapted to undergo bidirectional motion from this
central position. The rotational excursion of the platform and arm
is limited, typically being 30 degrees for the platform in either
direction from the central position, but this value shall in no way
be interpreted as limiting since, quite obviously, the rotational
excursion may be made greater or smaller to suit the conditions
desired.
Referring now also to the other figures, the handle bar 12 is
mounted upon the vertical extension 14 of the arm 15 which is
constructed with a lower horizontal section 16 extending from
beneath the platform 10. The horizontal section 16 of the arm 15 is
sufficiently long to cause the vertical extension 14 to clear the
peripheral surface of the platform 10 and the underlying support
structure.
The exercise apparatus is supported upon a floor by a set of feet
18, FIG. 3, which depend from a horizontal base plate 20. The arm
15 is pivotally anchored by a pin 22, extending vertically through
the arm section 16 into the base plate 20 at its lower end and into
a top support plate 24 at its upper end. The top plate 24 and base
plate 20 are secured in fixed spaced relation by a set of posts 26,
and these parts in combination form the stationary support for the
movable platform and arm. A pair of tubular spacers 28 encircling
the pin 22 retain the horizontal section 16 of the arm 15 in
predetermined horizontal position between the plates 20 and 24. The
pivot pin 22 is situated adjacent the free end of the arm 15 and
toward the rear of the exercise apparatus. In order to stabilize
the other end of the arm 15, a cross bar 30 is mounted upon the
horizontal section 16, FIG. 5, forward of the pin 22. A pair of
spaced rollers 32 journalled in the cross bar and adapted to roll
on the top surface of the plate 20 provide the stability for the
arm while permitting angular excursion of the arm 15.
A yoke 34 is slidably mounted upon the horizontal section 16. A pin
36 depends from the platform 10 and engages an aperture 37 in the
yoke 34. As the platform 10 rotates, the pin 36 via yoke 34 pivots
the arm section 16 about the pin 22. The yoke reciprocates along
the arm section 16 as the platform is rotated from its central
position to an angular displacement and returned. Angular
displacement .theta. of the arm is increased by moving the pin 36
toward the pivot pin 22 and is decreased by moving the pin toward
the center of rotation of the platform 10. Upon going beyond the
center of rotation of the platform, the arm will no longer
counterrotate, but undergo an angular excursion in the same
direction as the platform.
The platform 10 is mounted upon a ball bearing 40 which is nested
in the top plate 24, FIG. 3. A circular aperture 42 in the top
plate 24 guides the platform 10 in a circular path by virtue of
three depending rollers 44 fastened to the platform 10 and
cooperating with the vertical edge of the aperture 42, FIGS. 3 and
4. A lower flange 45, which is an integral part of each roller 44,
projects beneath the top plate 24 to prevent lifting of the
platform 10.
With the particular arrangement for instance, the arm rotates about
pin 22 by an angle .theta. either side from the central position
when the platform counterrotates about its center by the larger
angle .theta.'. A latch pin 50, FIG. 6, is provided to latch the
rotated arm 15 and platform 10 in either extreme position. The pin
50 is secured to a leaf spring 52 which allows the pin to run up a
ramp 54 as the arm section 16 approaches and drop into an aperture
56 of the arm section 16 to lock the arm in position. For
unlatching, the person performing the exercise squeezes the
appropriate hand grip 58, left or right on the handle bar 12, which
when squeezed to the predetermined extent raises through a flexible
cable 60 the lever 64 (FIG. 3) in the direction of arrow 65 to lift
the leaf 52 and consequently the pin 50 out of the aperture 56. The
lever 64 is pivotally fastened at 66. If the latching feature is
not desired, it can be disabled by rotating the respective handle
72 from position C to position D, FIG. 6, thus rotating an
eccentric cam 70 about pivot 71 to raise the leaf 52 and pin 50 to
the dotted position indicated by arrow 74.
The hand grip 58 includes resilient means, such as an air bulb 76
or spring means 76A, FIG. 8, to restore the lever and cable to its
normal non-actuated position. The latching and hand grip means are
designed primarily to provide exercise for the hand and arm muscles
of the person using the exercise apparatus. For requiring the use
of a predetermined amount of force, the bulb 76 may include an
adjustable vent valve which acts differentially, i.e., fluid is
expelled from the bulb slowly requiring increased force, but
admitted to the bulb rapidly, see for instance my copending
application for U.S. Letters Patent Ser. No. 189,354 filed Oct. 14,
1971. Alternatively, a compression spring 76A with or without force
adjusting means may be used, see FIG. 8. Still further, the
purchaser of the apparatus may be provided with a set of springs to
enable him to substitute increasingly forceful springs as the
exercise progresses.
A further feature of the present apparatus resides in the provision
of means for varying the resistance or "drag" of the platform to
rotational displacement. To this end, a friction shoe 80, FIG. 7,
is positioned for being urged into frictional contact with the
underside of the platform 10. The shoe is mounted to an arm 82
which extends through an aperture 83 in the top plate 24. The arm
82 is secured to a lever 84 which is supported by a centrally
located pivot 85. The opposite end of the lever 84 is constructed
to receive a helical spring 88 which is adapted to be compressed
beneath a washer 90 fastened to the lower end of an adjusting screw
92 threaded into the plate 24. By rotating the screw 92 the shoe 80
is urged into variable frictional contact with the underside of the
platform 10, thus requiring the expenditure of a greater or smaller
twisting effort to cause the desired rotational excursion of the
platform 10.
For providing vertical adjustment of the arm 15 as is required for
persons of different height, a slot 100 (FIG. 3) forms a bifurcated
lower end of the tube 102 which mounts the handle bar. The tube 102
is secured within the vertical extension 14 of the arm 15. Upon
tightening a nut 104 which draws a threaded wedge 106 into the tube
102, the bifurcated end is expanded against the inside of vertical
extension 14 to obtain a locking action.
It will be apparent to those skilled in the art that while two
latching arrangements are shown, one left and one right, the
apparatus may readily be redesigned to include only a single latch
with the manual gripping means located centrally.
When the latching arrangement is disabled the angular excursion of
the platform and arm still remains limited. As illustrated, the
edges 96, FIGS. 1 and 2, of the wrap around enclosure 98 limit the
motion of the arm. In order to prevent a sudden stop of the motion
of the platform and arm, padding may be used to soften the impact
or, alternatively, friction means are used to retard the motion of
the platform and arm as the limit of their angular excursions is
reached.
A further feature of the present apparatus will comprise a counting
means for counting the quantity of rotational motions imparted to
the platform. This may include a single counter for all motions or
separate counters for left and right rotation. The counter can be
coupled to the hand grip device 58 to separate or combine the
number of unlatching operations.
Instead of the yoke 34 and pin 36 mechanism described and
illustrated hereinabove, it will be apparent that other mechanisms
can be used to achieve coordinated counterrotation between the arm
15 and platform 10. Typical of such an alternative embodiment is
the use of two meshed gears in which case the platform is coupled
to one gear and the arm is pivotally fastened and rotated
responsive to the motion of the second gear. In this latter case,
if desired, it is possible to shorten the distance from the center
of rotation of the platform to the arm 15 as the arm undergoes its
angular rotation.
It will be apparent that the foregoing exercise apparatus
constitutes a most versatile and effective exercise and training
apparatus, useful for general fitness exercises, but also for
imparting the desired exercises to golfers and other and similar
sports enthusiasts. The striking simplicity of the present
apparatus renders it ideally suited for installation in the home,
office and professional establishments.
