Benefits of technology

[0007]It is another object of the present invention to provide an inflatable gymnastic auxiliary apparatus, which has a small size, convenient for delivery and storage.
[0008]It is still another object of the present invention to provide an inflatable gymnastic auxiliary apparatus, which facilitates rapid fabrication, improving the fabrication efficiency.
[0010]Subject to the above-stated design, the user can adjust the pressure in each enclosed inner shell to regulate the amount of deformation of the elongated body for providing a different hardness-softness subject to the actual requirement. During application, the user can use the inflatable gymnastic auxiliary apparatus to perform different postures. When using the inflatable gymnastic auxiliary apparatus to perform any posture, the inflatable gymnastic auxiliary apparatus can give a suitable pressure back to the user, achieving the effects of exercise. After each use, the user can discharge the air pressure out of each enclosed inner shell to reduce the size of the inflatable gymnastic auxiliary apparatus for delivery or storage.
[0011]Further, the fabrication of the inflatable gymnastic auxiliary apparatus utilizes well developed known techniques, avoiding long waiting time during fabrication and improving the fabrication efficiency.

Problems solved by technology

However, as the rolling auxiliary apparatus is made of a soft foam material, it does not allow adjustment of the hardness-softness and has a big size, not convenient for delivery or storage.
Further, when fabricating this design of rolling auxiliary apparatus, it wastes much waiting time during foam molding, lowering the fabrication efficiency.

first embodiment

[0029]Referring to FIG. 1, an inflatable gymnastic auxiliary apparatus 10 in accordance with 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 ...

second embodiment

[0035]Further, the elongated body can be made having more than one enclosed inner shell set therein. According to 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.

third embodiment

[0036]According to 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.

Abstract

An inflatable gymnastic auxiliary apparatus includes an elongated boy having an enclosed inner shell and an outer shell surrounding the enclosed inner shell, and an air valve installed in the elongated body in communication with the air chamber in the enclosed inner shell for enabling the elongated body to be inflated. Thus, the user can adjust the pressure in each enclosed inner shell to regulate the amount of deformation of the elongated body for providing a different hardness-softness subject to the actual requirement. After each use, the user can discharge the air pressure out of each enclosed inner shell to reduce the size of the inflatable gymnastic auxiliary apparatus for delivery or storage.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to gymnastics gears and more particularly, to an inflatable gymnastic auxiliary apparatus.[0003]2. Description of the Related Art[0004]Rhythmic exercise (such as Yoga or Pilates) is mainly for training the core muscle groups of the human body. As the health and strength of the core muscle groups take an important role in controlling the health of the whole body and the functioning of the internal organs, training the strength of the core muscle groups by means of exercising the limbs can refine body curves, correct bad posture and improve blood circulation.[0005]When performing rhythmic exercises, different gymnastic auxiliary apparatuses may be used to help body stretching. Taiwan Publication Number M369777 discloses a gymnastic auxiliary apparatus entitled “Rolling auxiliary apparatus for rhythmic exercises”. This rolling auxiliary apparatus is made of a soft foam material. When the human...
