BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] The present invention relates to an exercise device and more
particularly an exercise device with a wheel rotatable relative to
an axle having outwardly extending handles gripped by the user
wherein disc-like members situated adjacent the sides of the wheel
are fixed to the axle such that the rotating wheel does not rub
against the hands of the user to cause irritation or
discomfort.
[0006] 2. Description of Prior Art Including Information Disclosed
Under 37 CFR 1.97 and 1.98
[0007] Wheeled type exercise devices have been known in the art for
many years. For example, U.S. Pat. No. 3,809,393, issued May 7,
1974, discloses an exercising apparatus in which hand-held
platforms on wheels are moved about a surface while supporting in
varying degrees the weight of the upper body portion of a person
while exercising. The platforms are supported by at least three
swivel casters adapted to be independently moved about a floor
while being gripped by the hands of the user. The platforms define
a longitudinal axis around which the swivel casters are
symmetrically and fixedly disposed.
[0008] However, the individual hand-held platform devices of U.S.
Pat. No. 3,809,393 may be difficult to use. The devices tend to
move away from each other, and out from under the user, as the
user's body extends and retracts. When that occurs, the devices may
no longer be in position to support the weight of the user.
[0009] To overcome that problem, devices in the form of a single
wheel and axle have been developed. The axle extends as handles on
opposite, sides of the wheel so that the device can be gripped by
both hands of the user at the same time to provide better control
and stability. In use, the handles are grasped one in each hand of
the user upon assuming a kneeling position. By extending and
retracting the body, the wheel is moved back and forth along the
floor such that it rotates relative to the axle while supporting
the weight of the person's upper body portion on the handles,
thereby effectively exercising the muscles.
[0010] As disclosed in U.S. Pat. No. 3,752,475, issued Aug. 14,
1974, an improvement to the single wheel and axle device mentioned
above takes the form of an exercise wheel rotatable about a central
axis is provided with spring in operative association with the
wheel and axle to provide for increasing resistance to the rotation
of the wheel in one direction to further enhance the exercise
provided by the device.
[0011] Another version of the spring-loaded exercise wheel is
disclosed in U.S. Patent Publication No. 2012/0157274 of Jun. 21,
2012. That device includes a main wheel formed of a first angled
wheel part, and a second angled wheel part coupled to the first
wheel part with a flat band therebetween. The device includes a
pair of handles designed to be simultaneously gripped by the user
as the wheel rotates relative to the handles.
[0012] However, in the above devices, rotating the wheel relative
to the handles means that the side walls of the wheel move relative
to the user's hands which are grip the handles proximate the wheel.
As the wheel rotates in one direction and then back to its original
position in the reverse direction, the sides of the wheel rub
against the hands of the user, causing discomfort and
irritation.
[0013] It is therefore a main object of the present invention to
provide a wheel and axle type exercise device wherein rotation of
the wheel relative to the handles does not cause discomfort or
irritation to the skin of the hands gripping the handles.
[0014] It is another object of the present invention to provide a
wheel and axle type exercise device including a circular or
disc-like member radially extending from and fixedly mounted to the
axle at a position adjacent the side of the wheel, such that the
member does not move relative to the hands as the wheel
rotates.
[0015] It is another object of the present invention to provide a
wheel and axle type exercise device wherein the edge of the tread
surface of the wheel is defined by an inwardly directed channel and
the circular or disc-like member has an outer rim adapted to be
received in and freely move relative to the channel.
[0016] It is another object of the present invention to provide a
wheel and axle type exercise device wherein a coil spring is
operably interposed between the Wheel and the axle such that
rotation of the wheel relative to the axle in a first direction
increases the tension on the spring.
[0017] It is another object of the present invention to provide a
wheel and axle type exercise device wherein a coil spring is
operably interposed between the wheel and the axle such that
rotation of the wheel relative to the axle in the reverse direction
decreases the tension on the spring.

DETAILED DESCRIPTION OF THE INVENTION
[0047] As illustrated in the drawings, the present invention
relates to an exercise device, generally designated A, which
includes a wheel 10 and an axle assembly, the axle assembly being
generally designated B. Axle assembly B includes a hollow
cylindrical axle 12, preferably made of metal, and first and second
handle sections 14A and 14B extending from opposite sides of axle
12, outwardly from the sides of wheel 10. A coil spring 16 is
situated within wheel 10, surrounding axle 12, and more
particularly hub 25. Spring 16 is operably connected between wheel
10 and axle 12 such that the wheel and the axle can move relative
to each other to alter the tension on spring 16.
[0048] Axle assembly B also includes first and second generally
circular or disc-like members 18A, 18B. Members 18A and 18B are
generally parallel to each other and are fixedly mounted to and
radially extend from point proximate the opposite ends axle 12.
Members 18A, 18B move with axle 12 as a unit. Member 18A and 18B
cannot move relative to axle 12 or to each other.
[0049] As is best seen in FIGS. 6, 7 and 13, each of the members
18A, 18B preferably has a generally concave exterior surface. Each
member includes a rim with a radially outwardly directed
circumferential protrusion 20. Each member also has a central
opening 22 to accommodate the axle assembly.
[0050] As best seen in FIGS. 6, 7, 8 and 11, wheel 10 has a rigid
support structure including generally planar, spaced side support
panels 24A, 24B and a central support member 24C. The support
panels 24A 24B and central support member 24C all of extend in a
direction generally perpendicular to the axis of axle 12, and are
generally parallel to each other. Various reinforcing cross members
extend in a direction generally parallel to the axis of axle
12.
[0051] The wheel support structure is mounted on cylindrical hub 25
which is situated within the central portion of the wheel. Hub
portion 25 surrounds axle 12 and is surrounded by and supports coil
spring 16.
[0052] The support structure of wheel 10 also includes a rigid
curved outer surface 26. Outer surface 26 extends between the ends
of side support panels 24A and 24B and outwardly a short distance
beyond the planes of those panels. As seen in FIG. 12, the support
structure for wheel 10, including outer support surface 26, can be
formed of two halves, with the outer support surface in two parts
26A and 26B. The support surface halves can be assembled to form
the device and fastened together by glue or other conventional
means.
[0053] Wheel 10 has an exterior tread surface 28, fabricated of a
high friction material such as rubber, which is formed over and
supported by outer surface 26 of the support structure. Preferably,
tread surface 28 has a pattern of tread lines cut into it to
increase the friction between the wheel and the floor or other
surface upon which the device is being used.
[0054] As best seen in FIGS. 8 and 12, each edge of outer support
surface 26 overlaps and extends beyond the side support panels 24
and is defined by an inwardly facing peripheral channel 30. Each of
the members 18A, 18B is aligned with a different one of the edges
of outer support surface 26. Each channel 30 is adapted to freely
moveably receive the protrusion 20 of the rim of the member 18
aligned therewith, such that the members 18 and the wheel 10 can
freely move relative to each other.
[0055] Accordingly, members 18 will remain in a fixed position with
respect to the axle assembly as the wheel 10 is moved relative to
the axle assembly. In that way, the hands of the user, when
gripping handle sections 14A and 14B and linearly moving the device
along the floor or other surface, are shielded from the movement of
the wheel and hence from any abrasion of the skin which could
result from the rotating wheel coming in contact with the user's
hands.
[0056] As best seen in FIGS. 8, 10 and 11, axle 12 extends
outwardly of side support panels 24A and 24B at either end. Each
side support panel has a central opening and is mounted on and
fixed to a different collar 32A, 32B. The axle assembly includes
hollow cylindrical members 34A, 34B fixed to axle 12 which extend
through collars 32A, 32B at either end of the axle such that the
collars and wheel 10, can rotate relative to axle 12.
[0057] Handle support members 36A, 36B are removeably received in
the opposite ends of axle 12. Handle sections 14A, 14B are mounted
over members 36A, 36B, respectively. As can be seen from FIG. 12,
each handle section 14A and 14B can be provided in two halves with
a grip portion molded around the halves.
[0058] Each of the handle support members 36A and 36B has a longer
portion, over which the handle section is received, and a shorter
portion, which is received within the end of axle 12. The axis of
the longer portion and the axis of the shorter portion of each
handle support member are not collinear. Instead, the longer and
shorter portions are situated at an obtuse angle with respect to
each other. Thus, the axes of the handle sections 14A and 14B are
situated at an obtuse angle with respect to axle 12, as seen in the
drawings.
[0059] Coil spring 16 is situated within wheel 10 around axle 12
and hub 25. It is operably connected between the axle 12 and wheel
10. FIGS. 9 and 10 show the spring mounted to the axle, with and
without hub 25.
[0060] As best seen in FIGS. 6 and 7, spring 16 has a first end 38
and a second end 40. The first end 38 engages panel 24B of the
wheel support structure. The second end 40 of spring 16 is attached
to the axle 12 of assembly B. As the device is moved by the user in
one direction along a surface, the wheel rotates relative to the
axle and the tension on spring increases. As the device is moved by
the user in the other direction along a surface, the wheel rotates
relative to the axle in the opposite direction and the tension on
spring decreases.
[0061] In use, the user of the exercise device positions him or
herself on bended knees on a surface, such as a floor. The user
grips the handle sections of the device with both hands, one on
each side of the wheel, with the hands proximate the wheel,
adjacent to radially extending members 18. He or she situates the
device in front of him or her such that the tread surface of the
wheel frictionally engages the floor. The user then extends his or
her body to move the device relative to the floor surface in a
first direction, away from the user. That causes the wheel to
rotate relative to the gripped handle sections, thereby increasing
the tension on the spring. However, since members 18 adjacent the
sides of the wheel are fixed on the handle sections and therefore
remain stationary relative to the axle as the wheel rotates, the
device does not rub against the hands of the user and hands of the
user cannot be irritated or discomforted by the rotation of the
wheel.
[0062] Thereafter, the user retracts his or her body back toward
its original position, rotating the wheel relative to the gripped
handle sections in the opposite direction, to decrease the tension
on the spring. Again, since members 18 are fixed on the handle
sections and remain stationary relative to the axle as the wheel
rotates, and the hands of the user cannot be irritated or
discomforted by the rotation of the wheel. The back and forth
motion of the user is repeated to exercise the body of the user
without rubbing the hands of the user.
[0063] While only a single preferred embodiment of the present
invention has been disclosed for purposes of illustration, it is
obvious that many modifications and variations could be made
thereto. It is intended to cover all of those modifications and
variations which fall within the scope of the present invention, as
defined by the following claims.
