Description
BACKGROUND OF THE INVENTION
[0001] The present invention generally relates to abdominal
exercise devices. More particularly, the present invention relates
to a portable abdominal exercise device for use in association with
a chair, and which can be stored and transported easily.
[0002] Abdominal exercises, such as crunches or sit-ups, are
performed to strengthen the abdominal and lower back muscles. It is
well-known that performing abdominal exercises can strengthen the
back to avoid back injuries, and trim the waist of the exerciser.
These abdominal exercises are performed by bringing the torso
towards the bent knees of the exerciser. Such exercises can be
performed while sitting in a chair, or lying on the ground. When
lying on the ground, gravity provides resistance to raising the
torso towards the knees resulting in increased strength to the
abdominal muscles. The resistance of gravity while performing such
exercises when seated in a chair only has an effect when raising
the torso away from the knees, thus lessening the desired effect on
the abdominal muscles.
[0003] There exist many abdominal muscle exercising machines. Some
of these are large and cumbersome and restricted to the gym or home
setting. Others are more portable, but still rather complicated in
use or generally ineffective. Moreover, even many of these
"portable" exercise devices are not very compact for storage and
transportation, such as when traveling.
[0004] Accordingly, there is a continuing need for an abdominal
exercise device which is portable and which can be disassembled for
ease of transportation such as when traveling. Such an abdominal
exercise device should assist a user thereof in obtaining
resistance, and thus target the abdominal muscles, when in the
seated position. The present invention fulfills these needs and
provides other related advantages.
SUMMARY OF THE INVENTION
[0005] The present invention resides in a portable exercise device
for use in association with a backrest of a chair. The abdominal
exercise device of the present invention is small, can be
disassembled for transportation, and is relatively inexpensive.
[0006] The abdominal exercise device of the present invention
includes one or more elastomeric resistance bands which are adapted
to encircle the backrest of the chair. The one or more elastomeric
resistance bands are preferably connected to a back support plate.
Typically, the back support plate includes means on opposing edges
thereof for removably receiving ends of the resistance bands. In a
particularly preferred embodiment, such means comprise slots
extending from edges of the back support plate to apertures formed
in the back support plate. A portion of the resistance band can be
inserted into the slot, and ends of the resistance bands are
enlarged with respect to the apertures so as not to pass
therethrough. Although as few as a single resistance band may be
used, preferably multiple resistance bands are utilized so that the
amount of the resistance can be varied.
[0007] An elongated strap adapted to fit a torso of a user is
typically connected to the back support plate, although the
resistance bands may be directly connected to the elongated strap.
The back support plate includes a pair of spaced apart apertures
which removably accept the strap therethrough in looped fashion.
The strap has free ends including means which are adapted to be
releasably coupled to one another. Preferably, the strap is
adjustable in length and includes padded sections for user
comfort.
[0008] In use, the one or more elastic bands are stretched over the
backrest of the chair and coupled to the back support plate. The
elongated strap is connected to the back support plate, and coupled
to the torso of the user. As the user moves his or her torso away
from the backrest and towards his or her knees, the elastomeric
bands resist this movement causing the muscles to experience
resistance.
[0009] Other features and advantages of the present invention will
become apparent from the following more detailed description, taken
in conjunction with the accompanying drawings, which illustrate, by
way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] As shown in the accompanying drawings for purposes of
illustration, the present invention resides in a portable abdominal
exercise device, generally referred to by the reference number 10,
which is particularly adapted for use in association with a
backrest 12 of a chair 14 to provide resistance to a user 16 seated
in the chair 14 while performing abdominal exercises.
[0018] With reference to FIGS. 1 and 2, an exercise device 10
embodying the present invention is coupled to the backrest 12 of a
chair 14 and to a user 16 seated in the chair 14. As the user 16
bends forward so that a torso of a user is brought towards the
knees of the seated user, the device 10 of the present invention
provides resistance to this movement and causes additional
strengthening of the abdominal and lower back muscles so as to
enhance the effect of the exercise.
[0019] With reference now to FIGS. 3-5, the device 10 is comprised
of three general components. At least one, and preferably multiple,
resistance bands 18 comprised of an elastomeric material which is
capable of being stretched and returned to its rested state are
provided. The resistance bands 18 are of such a length so as to
extend around the backrest 12 of a chair 14, as illustrated in
FIGS. 1, 2 and 6. The resistance bands 18 can be comprised of
bungee-type material, surgical tubing, or any other similar
material. The resistance bands 18 may be provided in different
lengths so as to accommodate backrests 12 of different dimension,
or to enable the user 16 to have greater motion during the
abdominal exercise. However, it has been found that a majority of
backrests 12 are of a certain range in width, and the range of
movement for the typical seated crunch is preferably limited, so
the resistance bands 18 are typically offered in a single length.
It will be appreciated by those skilled in the art, that the
provision of multiple resistance bands 18 allows the user 16 to
alter the resistance by using more or less resistance bands 18 as
need dictates.
[0020] The resistance bands 18 are preferably connected to a back
support plate 20. Although the resistance bands 18 may be
permanently attached to the back support plate 20, in a
particularly preferred embodiment, the resistance bands 18 are
removably connected to the back support plate 20 so that the
resistance of the device 10 can be altered, and the device 10 can
be easily disassembled for compact storage and transportation, such
as when traveling. Accordingly, the back support plate 20 includes
means for removably attaching to the free ends 22 of the resistance
bands 18. In a particularly preferred embodiment, as illustrated,
opposing edges of the back support plate 20 include a plurality of
slots 24 which extend to apertures 26. The free ends 22 of the
resistance bands 18 are enlarged. In a particularly preferred
embodiment, surgical-type tubing comprises the resistance bands 18.
Steel or plastic balls are inserted into the open free end to
enlarge the end 22. The elastomeric tubing is slid through the slot
24 until the enlarged end 22 contacts the aperture 26. As the
enlarged end 22 is larger than the aperture 26, it cannot pass
therethrough and thus the free ends 22 of the resistance bands 18
are releasably held to the back support plate 20. Such arrangement
is shown in FIGS. 4 and 5.
[0021] As shown in the various figures, an elongated strap 28 is
connected to the back support plate, generally opposite the
resistance bands 18. To facilitate transport and storage of the
device 10, the strap 28 is preferably removably attached to the
back support plate 20. In this regard, the back support plate 20
includes spaced apart slots 30 which are configured to receive the
strap 28 therethrough, as shown in FIG. 4. The strap 28 may be
comprised of leather, canvas, cloth or other suitable material.
Free ends of the strap 28 include means, such as the illustrated
mating clip ends 32 and 34, for being removably attached or
otherwise coupled to one another so as to permit the strap 28 to be
secured about a torso of the user 16, such as illustrated in FIG.
1. The strap 28 is also preferably adjustable in length so as to
accommodate user 16 of different sizes. Preferably, the coupling
means 32 and 34 also includes means for adjusting the length of the
strap, such as looping the ends 36 of the strap through an
elongated slot member of the clip portions 32 and 34. The strap 28
also preferably includes padded sections 38 which are typically
positioned about the shoulders or arms of the user 16, as
illustrated in FIGS. 1 and 2, to provide comfort to the user.
[0022] In use, as shown in FIGS. 1, 2 and 6, the desired number of
resistance bands 18 are attached to the back support plate 20, as
described above. The strap 28 is looped through the slots 30 of the
back support plate 20. The device 10 is positioned over a backrest
12 of a chair 14 by extending the one or more resistance bands 18
behind the backrest 12, with the back support plate 20 positioned
in front of the backrest 12. The user 16 then sits in the chair and
secures the strap 28 securely about his or her torso area while
seated in an upright position, as illustrated in FIG. 1. The user
16 then performs abdominal seated crunches by moving his or her
torso away from the backrest 12 and towards his or her knees. The
resistance bands 18 resist this forward motion and serve to
exercise the abdominal muscles and lower back muscles as the user
16 performs these exercises.
[0023] It will be appreciated by those skilled in the art that the
device 10 of the present invention is simple in operation and
relatively inexpensive. Furthermore, the device 10 is small so as
to be portable. Due to its design, the device 10 can be
disassembled so that it can be easily transported and stored. The
device 10 of the present invention also provides varying resistance
by changing the number or type of resistance bands 18.
[0024] Although several embodiments have been described in detail
for purposes of illustration, various modifications may be made
with out departing from the scope and spirit of the invention.
Accordingly, the invention is not to be limited, except as by the
appended claims.
