Exercise device

An exercising device including an inflatable flexible toroidal member such as a tire tube, a substantially rigid platform disposed over and supported by the toroidal member, and foot treads positioned on the platform. The exercising device can be used not only for jogging, running, or jumping in place, but with the addition of an exercising board and an exercising stand, can also be used for sit-ups and the like.

BACKGROUND OF THE INVENTION 
This invention relates to an exercise device, and more particularly to a 
resilient exercise device permitting in place exercising. 
With a continuous increased awareness of the importance of exercising, 
numerous exercising devices are readily available to provide assistance in 
carrying out various exercises. One of the most popular types of exercices 
is that of jogging. However, normally, jogging requires a large area or 
track, and in most cases this exercise must be done on the outside. As a 
result, many people are prevented from jogging because of the lack of 
suitable outdoor facilities. In order to alleviate this situation, many 
types of indoor jogging apparatus are available to permit jogging in place 
so as to permit indoor jogging. For example, mechanized treadmills and the 
like are readily available. 
Most of the apparatus utilized for jogging are quite costly, cumbersome, 
and are not very convenient. For example, some of these devices have a 
flat surface on which the individual runs or jumps. The running or jumping 
is usually quite noisy thereby causing a disturbance to those around the 
jogger. Also, because of the flat surface, there is a hard impact on the 
bottom of the feet of the jogger. Additionally, when jogging outside on a 
terrain other than a flat hard surface, the ground is uneven. This uneven 
ground actually benefits the jogger since it requires greater exertion due 
to the shifting of the center of gravity of the body and the constant 
muscular action necessary to maintain body balance. However, most indoor 
jogging apparatus are of the flat surface type and thereby avoid the 
benefits available from jogging on an uneven ground surface. 
Accordingly, it would be convenient to have an exercising device which can 
be utilized for indoor jogging, walking, or jumping in place, and which 
would avoid or reduce the pounding impact noise to thereby eliminate the 
disturbance to others. At the same time, the device should be resilient to 
avoid the hard impact of the jumping exercising to thereby soften the blow 
to the feet of the jogger. Also, it would be convenient to provide a 
flexible surface which simulates the uneven terrain of an outside jogging 
track to thereby provide increased use of the jogger's muscles. 
Additionally, many types of exercising devices are dedicated to one 
particular type of exercise. When one wants to vary the types of 
exercises, he must use many separate and independent pieces of equipment. 
This results in a costly situation as well as a space problem since each 
of these devices must occupy a separate part of a gym or other exercise 
room. 
It would therefore also be convenient to have an exercise device which in 
addition to providing the benefits of indoor jogging and the like, can 
also be utilized to accommodate other pieces of exercising equiment to 
thereby effectively produce an exercising device having broader 
capabilities than a simple jogging apparatus. 
SUMMARY OF THE INVENTION 
Accordingly, it is an object of the present invention to provide an 
exercising device which avoids the aforementioned problems of prior art 
devices. 
Another object of the present invention is to provide an exercising device 
which can be utilized for jogging, running, or jumping in place, and which 
provides a flexible surface to thereby eliminate the hard impact on the 
feet of a jogger. 
Still a further object of the present invention is to provide an exercising 
device which permits jogging, running or jumping in place, and avoids the 
disturbing pounding noise normally associated with such activities. 
Another object of the present invention is to provide an exercising device 
which permits jogging, running, or jumping in place, and simulates a rough 
terrain to thereby require greater exertion and greater use of the user's 
muscles in order to maintain the center of gravity of the user's body in 
an upright balanced position. 
Yet a further object of the present invention is to provide an exercising 
device which can be used for jogging in place, and can also be used to 
accommodate other pieces of exercising equipment, such as an exercising 
board and an exercising stand. 
A further object of the present invention is to provide an exercising stand 
which can be utilized for various exercises, and which can accommodate 
other pieces of exercising equipment, such as an exercising board and an 
exercising resilient platform. 
Briefly, in accordance with the present invention, there is provided an 
exercising device having an inflatable flexible toroidal member such as a 
tire tube. A substantially rigid platform is disposed over and supported 
by the toroidal member. Foot treads are positioned on the platform. 
In one embodiment of the present invention, the platform itself can have a 
degree of flexibility by forming it of a plurality of elongated rigid 
slats which are separated from each other by resilient spacers. 
The toroidal member can be wrapped, by means of an adhesive wrap, to 
maintain it in its toroidal configuration thereby avoiding bulges. 
Furthermore, in order to accommodate an oval shaped platform, a band can 
be placed around the midsection of the toroidal member to reshape it into 
an oval configuration corresponding to the platform. 
The present invention further contemplates the use of an exercising board 
which can be balanced across the toroidal member. One end of the 
exercising board can be elevated by inserting it into an exercising stand. 
The exercising stand includes a base with a pair of upstanding sidewalls 
and a top wall. A shelf is positioned between the upstanding walls and 
spaced below the top wall. The top wall is rearwardly displaced from the 
shelf to permit easy access to the shelf. A pair of facing channels are 
formed into the sidewalls to form a slot which receives and holds the 
exercising board in the elevated position.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring now to FIGS. 1-4, there is generally shown an exercising device 
at 10 having a lower resilient assembly 12 and an upper platform assembly 
14. The lower assembly 12 includes an inflatable toroidal member 16, such 
as a tire tube, which can be inflated by means of a standard valve 
assembly 18. In order to maintain the toroidal member 16 in an annular 
configuration and avoid bulges thereon, the toroidal member 16 can be 
transversely wrapped with a strip 20 with adjacent transverse sections of 
the strip overlapping to thereby completely cover the entire surface of 
the toroidal member, as best shown in FIG. 3. The particular strip 20 can 
be any type of wrapping material, such as an elastic band 22, and can 
include an adhesive surface 24 on one side to provide self sticking inner 
surface for the wrapping strip. 
A heavy duty resilient band 26 can be placed about the mid section of the 
toroidal member 16 to diametrically squeeze the mid section thereby 
reshaping the toroidal member into an oval configuration, as best shown in 
FIG. 4. The band 26 can be either a continuous endless band or it can be 
made into a loop when the ends 28, 30 are fastened together in a 
conventional manner. The material of the band 26 can be of any heavy duty 
rubber or plastic material. Furthermore, the shape of the toroidal member 
16 can be structured into various configurations using such a band 26. 
The platform assembly 14 as can best be seen in FIGS. 1 and 2, comprises a 
base section 32 formed of a plurality of elongated slats 34 with adjacent 
slats being spaced apart by resilient members or pads 36, 38. The slats 34 
can typically be made of wood with the resilient pads 36, 38 being made of 
rubber, plastic or similar resilient material. The resilient pads, 36, 38 
can be of rectangular shape positioned in two spaced apart rows, with one 
row of the pads 36 being adjacent one side of the base section 32, and the 
other row of the pads 38 being positioned adjacent the other side of the 
base section 32. The portions transversely between each pair of spacers or 
pads 36, 38 are left empty to provide a space between adjacent slats 34. 
The spacers 36, 38 can be glued or cemented between adjacent slats. The 
slats 34 are configured so that their upper surfaces 40 lie in a common 
upper plane, and their lower surfaces 42 lie in a lower common plane. The 
corner edges of the base section 32 are champhered at 44. 
Axial holes or keyways 46, 48 are respectively formed through both the 
entire stack of adjacent slats 34 and the interspersed spacers 36, 38. 
Keyway 46 passes through the spacers 36, while the keyway 48 is positioned 
to pass through the spacers 38. 
Rods 50, 52 pass through the respective keyways 46, 48 and are held at 
opposing ends by means of the clamping washers 54, which are crimped onto 
the ends of the rods 50, 52. The rods 50, 52 serve to retain and hold the 
stack of elongated slats and spacers together. Preferably, the rods 50, 52 
are resilient, being fabricated from rubber, plastic and like material. 
Beneath the base section 32 are base pads 56, 58 formed of resilient 
material, such as rubber or plastic. The base pads 56, 58 are elongated 
with their elongated axis lying parallel to the elongated axis of the 
slats 34. The base pads 56, 58 have a width spanning a number of slats 34. 
The length of the base pads 56, 58 is slightly shorter than the elongated 
length of the slats 34. 
The base pads 56, 58 are secured directly onto the slats 34 of the base 
section 32, using suitable glue, cement and the like. The base pads 56, 58 
are spaced apart on the base section 32 leaving the mid section of the 
base section 32 exposed. As shown in FIG. 4, the corners of the base pads 
56, 58 may overlie the edges of the oval shaped toroidal member 16. 
However, the center spacing between the base pads is free. Accordingly, 
the wrapped toroidal member 16 is secured directly onto the base pads 56, 
58, using suitable glue, cement and the like, whereby the portions of the 
toroidal member 16 between the base pads 56, 58 are free. The base section 
32 formed with the elongated slats 34 is thus positioned over the base 
pads 56, 58 to overhang the base pads 56, 58 as well as overhang the oval 
shaped toroidal member 16, as can best be seen in FIG. 4. 
Placed over the base section 32 is an elongated strip 60 having its 
elongated axis perpendicular to the elongated axis of the individual slats 
34. Accordingly, the strip 60 is placed transversely across each of the 
slats 34 and is of a length substantially equal to the length of the base 
section 32. The width of the strip 60 is approximately equal to or 
slightly less than the transverse spacing between the resilient spacers 
36, 38. The strip 60 is typically made of a pliant material, such as 
canvas. 
Positioned on top of the strip 60, are two treads 62, 64. Each of the 
treads is formed of a multilayer construction with each of the lower 
layers 66, 68 respectively being of a firm material such as a wooden pad. 
A soft cushion material is placed respectively on top of the wooden pads, 
such as the layers 70, 72 formed of rubber or plastic material. The treads 
62, 64 are elongated with their elongated axis being parallel to the 
elongated axis of the slats 34. The width of each tread 62, 64 spans a 
number of slats and approximately equals the corresponding width of the 
pads 56, 68 positioned therebeneath. The length of the treads 62, 64 is 
less than the length of each of the slats, being approximately equal to 
the length of the pads 56, 58 therebeneath. 
When assembled, glue or other adhesive material can be used to hold the 
various sections together. Specifically, the layers forming the treads 62, 
64 can be secured together by means of adhesive. The treads themselves are 
secured onto the slats 34 and the strip 60, as well securing the strip 60 
onto the slats 34, by means of a suitable adhesive 73 so that the treads 
62, 64 are parallel to the slats 34, as shown in FIG. 8. As stated above, 
the base section 32 is adhesively secured to the base pads 56, 58 which in 
turn are adhesively secured to the toroidal resilient member 16. 
With the parts assembled, an individual user can walk, jump, or run in 
place with the user's feet positioned on top of the treads. When exerting 
the user's weight on one foot, the tread under that foot will press down 
onto the base section 32. Although the base section 32 is substantially 
rigid, because of the slat construction and the resiliency provided by the 
spacers 36, 38 between the slats 34, portions of the base section 34 
beneath the tread receiving the weight of the user will slightly flex with 
respect to the remaining portions of the base section which do not have 
any weight thereon. The strip 60 will serve to smooth or spread out the 
load from the particular slats receiving the weight onto the next few 
slats to thereby distribute the load. 
By means of the device heretofore described, the individual user can 
exercise by jogging or jumping in place. The specific pounding normally 
associated with jogging or jumping will not produce the normal loud noises 
because of the flexibility of the toroidal member or tube on the bottom of 
the exercising device. Therefore, there will be little or no disturbance 
to other people in the area. 
At the same time, because of the presence of the flexible toroidal member 
16, the jogger will not pound down on a very hard surface, but will jump 
onto a resilient surface which will absorb some of the jumping impact 
force. This makes the jogging or jumping easier than on a hard surface. 
However, even though the toroidal member 16 is flexible in order to absorb 
some of the initial impact of the jumping or jogging, at the same time the 
platform assembly will provide a sufficiently rigid surface to support the 
jogger so that the user will not fall off or lose his balance when jogging 
on the device. 
Because the toroidal member 16 does flex, additional muscle structure of 
the user is utilized when jogging, since the surface beneath each foot of 
the user will give and will thereby simulate an outdoor terrain which is 
somewhat uneven and not completely uniformly flat. This will supply the 
benefit of additional muscular exertion on the part of the jogger. 
In addition to the particular exercises which can be achieved directly on 
the jogging device 10 shown in FIGS. 1-4, by utilizing additional external 
equipment in association with the jogging device 10 of FIGS. 1-4, numerous 
other exercises can also be achieved. Specifically, referring now to FIG. 
5, there is shown an exercising board 74 formed of an elongated rigid 
board member 76 having a cushion or pad 78 provided along a substantial 
portion of its midsection. The pad 78 is secured on the board member by 
glue, cement or like adhesive means in a conventional manner. 
At one end of the board 74, there is provided a pillow 80 fabricated from a 
resilient or cushion type material. The opposite end 82 of the board 74 is 
free of any material. The board itself can be utilized for various 
exercises, such as for example, situps, legups, etc. In doing these 
exercises, it would be helpful if the user would have the ability of 
having his feet held during the situps. Also, it would be beneficial to 
have the ability of elevating the foot end 82 of the exercising board 74. 
To achieve these capabilities, there is also provided an additional 
exercising device, shown as an exercising stand 84 in FIGS. 6 and 7. It 
should be appreciated, that FIGS. 6 and 7 show an enlarged view of the 
exercising stand 84 as compared with the view taken of the exercising 
board 74 in FIG. 5. The relative sizes is better appreciated in FIG. 8, as 
will hereinafter be explained. 
The exercising stand 84 includes a base member 86 with two opposing 
upstanding sidewalls 88, 90 mounted thereon. The sidewalls 88, 90 
terminate in a top wall 92 spanning the sidewalls 88, 90. Positioned 
beneath the top wall 92 and extending between the sidewalls 88, 90, there 
is a transverse shelf 94. Both the top wall 92 and the shelf 94 are 
covered with a cushion material, such as rubber or carpeting 96, 98, 
respectively. 
The upper portions of the respective sidewalls 88, 90, extending from the 
shelf 94 to the top wall 92, are rearwardly directed and upwardly tapered, 
as shown best in FIG. 8. In this manner, the top wall 92 is rearward of 
the shelf 94 so as to expose the shelf 94 and facilitate the placing of 
feet of the user onto the shelf 94 without interference from the top wall 
92. At the same time, the top wall 92 can be held from the rear by an 
exerciser without interference from the shelf 94. 
Directly beneath the shelf 94 are an opposing pair of channels 100, 102 
facing each other, and extending into and across the entire width of the 
walls 88, 90. The two channels 100, 102 define a receiving slot for 
receiving the foot end 82 of the exercising board 74. 
The exercising board 74 in conjunction with the exercising stand 84, as 
well as the exercising device 10 shown in FIG. 1, can all be combined for 
use as a single exercising unit, as shown in FIG. 8. More specifically, 
the exercising board 74 can be secured onto the exercising device 10 of 
FIG. 1 by sliding it beneath the base section 32. Specifically, it can be 
placed in the space between the adjacent base pads 56, 58 so that it is 
positioned directly on the wrapped toroidal member 16 and beneath the 
slats 34, with the slats 34 resting on the cushion 78. The exercising 
board 74 is placed with its midsection positioned and balanced over the 
toroidal member 16 and the band 26. If desired, the band 26 can be 
repositioned 90 degrees into alignment with the strip 60 so that the band 
26 would overlie the cushion 78 and board 74 for a better securement 
against the toroidal member 16. The foot end 82 of the board 74 is then 
slid through the opposing channels 100, 102 of the exercising stand 84 so 
that it is elevated. The pillow 80, positioned at the other end of the 
board 74, rests on the floor. 
Using the arrangement shown in FIG. 8, an individual can lie down onto the 
base section 32 and place the heels of his feet on the shelf cushion 98 of 
the exercising stand 84 and have his toe portions retained behind the 
cushion 96 of the top wall 92. His head can then be placed on the pillow 
80, and he can then do various types of situp exercises. Additionally, 
other types of exercises could be done with this arrangement, including 
feet lifts, knee bends from a lying position, etc. 
It should be appreciated, that by utilizing the toroidal member 16 beneath 
the exercising board 74, the board 74 will not be as hard, and there will 
be some flexure in the toroidal member 16 as the individual continuously 
does his exercises. This flexure relieves some of the rigidity beneath the 
individual doing the exercises, thereby making it more convenient and less 
painful, while at the same time not losing any of the muscular benefits 
derived from the exercises. 
Although the exercising board 74 and stand 84 were shown for use in 
conjunction with the exercising device 10 of FIGS. 1-4, it should be 
appreciated that the exercising stand 84 or board 74 can also be used 
independently. However, because of their ability to be combined, cost and 
space is reduced. 
Although the oval shape of the toroidal member 16 was shown elongated in 
one direction, it should be appreciated that the base section 32 could be 
elongated in the opposite direction making it longer in the direction of 
the slats 34. Accordingly, the oval shape of the toroidal member 16 would 
be placed in the opposing direction, as indicated above with respect to 
the repositioning of the band 26. 
There has been described heretofore the best embodiment of the invention 
presently contemplated. However, it is to be understood that various 
changes and modifications may be made thereto without departing from the 
spirit of the present invention.
