DETAILED DESCRIPTION OF THE INVENTION
[0029] Referring to FIG. 1, an inflatable gymnastic auxiliary
apparatus 10 in accordance with a first embodiment of the invention
is shown comprising an elongated body 20 and an air valve 22.
[0030] Referring also to FIG. 2 and FIG. 3, the elongated body 20
has a circular cross section. Further, the elongated body 20
comprises an enclosed inner shell 30 and an outer shell 40
surrounding the enclosed inner shell 30. The enclosed inner shell
30 is made of an environmentally friendly material, such as
polyurethane or natural rubber, and covered with a layer of cloth
covering 34, defining therein an air chamber 32. The outer shell 40
is also made of an environmentally friendly material, such as
polyurethane or natural rubber, having its inner surface adhered to
the outer surface of the enclosed inner shell 30. Thus, the cloth
covering 34 is disposed in between the enclosed inner shell 30 and
the outer shell 40. Further, the elongated body 20 has a uniform
diameter extending along the length.
[0031] The air valve 22 is installed in elongated body 20 in
communication with the air chamber 32. Thus, air can be pumped
through the air valve 22 into the air chamber 32 to inflate the
elongated body 20. Subject to the design of the cloth covering 34,
the elongated body 20 will not be excessively inflated.
[0032] Thus, when pumping air through the air valve 22 into the air
chamber 32 to inflate the elongated body 20, the user can control
the air pressure in the air chamber 32 to regulate the amount of
deformation of the elongated body 20 for providing a different
hardness-softness subject to the actual requirement. During
application, the user can use the inflatable gymnastic auxiliary
apparatus 10 to perform different postures, for example, the user
can rest the back on the inflatable gymnastic auxiliary apparatus
10, or rest the chest and the abdomen on the inflatable gymnastic
auxiliary apparatus 10, or directly hug the inflatable gymnastic
auxiliary apparatus 10. When using the inflatable gymnastic
auxiliary apparatus 10 to perform any posture, the inflatable
gymnastic auxiliary apparatus 10 can give a pressure back to the
user, achieving the effects of exercise. After each use, the user
can discharge the air pressure out of the air chamber 32, as shown
in FIG. 4, to reduce the size of the inflatable gymnastic auxiliary
apparatus 10 for delivery or storage.
[0033] Further, the materials selected for the inflatable gymnastic
auxiliary apparatus 10 include two layers of polyurethane or
natural rubber and one cloth layer sandwiched between the two
layers of polyurethane or natural rubber. Thus, the fabrication of
the inflatable gymnastic auxiliary apparatus does not waste any
time in waiting for foam molding, improving the fabrication
efficiency.
[0034] To fit different application requirements and to provide
different application effects, the cross section of the elongated
body 20 is not limited to a circular shape. For example, the
elongated body 20 can be made having a semicircular cross section
as shown in FIG. 5, or a multilateral cross section, as shown in
FIG. 6. Further, the elongated body 20 can be made having different
diameters at different segments, for example, the elongated body 20
can be made having big diameter portions 202 and small diameter
portions 204 alternatively arranged along the length, as shown in
FIG. 7. Further, the elongated body 20 can be made having anti-slip
beads 42 evenly distributed over the outer surface of the outer
shell 40, as shown in FIG. 8, for positive resting of the human
body. Alternatively, the elongated body 20 can be made having
massaging beads 44 evenly distributed over the outer surface of the
outer shell 40, as shown in FIG. 9, for giving a massaging effect
to the user when the user presses his (her) body on the elongated
body 20. Further, the outer shell 40 of the elongated body 20 can
be made to exhibit a series of graphic elements by means of
printing or any other techniques, enhancing user's performance.
[0035] Further, the elongated body can be made having more than one
enclosed inner shell set therein. According to a second embodiment
of the present invention as shown in FIG. 10, the inflatable
gymnastic auxiliary apparatus 50 comprises an elongated body 60,
which has two enclosed inner shells 62 set therein, and two air
valves 66 respectively installed in the two distal ends of the
elongated body 60 and respectively connected to the two enclosed
inner shells 62. This design allows the user to separately adjust
the air pressure in each of the two enclosed inner shells 62 so
that the elongated body 60 can have a different hardness-softness
at a different location.
[0036] According to a third embodiment of the present invention as
shown in FIG. 11, the inflatable gymnastic auxiliary apparatus 70
comprises an elongated body 80, which has three enclosed inner
shells 82 set therein, and three air valves 86 installed in the
elongated body 60 at different locations and respectively connected
to the three enclosed inner shells 82. As the middle part of the
elongated body 80 is most frequently used part, the enclosed inner
shell 82 that is set on the middle is relatively shorter than the
other two enclosed inner shells 82, i.e., the length of the air
chamber 84 on the middle is relatively shorter than the other two
air chambers 84 so that the middle part of the elongated body 80
can be relatively harder than the other part of the elongated body
80 to meet actual status of use for better performance.
[0037] Although particular embodiments of the invention have been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
