For example, in the case of beauty purpose, the length of the stretchable body is desirably set longer than the stretchable body for toys. Think. In other words, in the case of cosmetic purposes, it is desirable to set the length of the stretchable body longer so that the stretchable body does not extend over the entire length unless a larger amount of air is blown.

  However, because the stretchable body is made of a material with low rigidity such as paper, if the stretchable body is long, the stretchable body does not stretch straight due to its own weight when it is blown and stretched, and it hangs down or bends. In addition to the poor appearance, there is a risk that a sense of accomplishment and exhilaration cannot be felt. In addition, when the stretchable body is long, when it is wound in a spiral shape, it is not properly (cleanly) wound and its shape is lost, and not only the appearance is bad, but also the stretchable body may be quickly deteriorated.

That is, the length L1 of the expansion / contraction body 2 is set so that the amount of air required for extending the expansion / contraction body 2 over the entire length L1 becomes an appropriate amount of air set in advance according to the purpose of use. In this embodiment, health promotion and beauty are intended for use, and it is set longer (for example, about 1 m) than a normal blowback.

  The linear body 3 is a wire rod that has elasticity and is disposed straight along the longitudinal direction of the stretchable body 2. That is, it is made of a stainless steel wire, and in a state where no external force is applied (a state where air is not blown into the expansion / contraction body 2), the wire is wound in a spiral shape or coil shape, and when it is straightened to release the external force, it returns to a spiral shape. The elastic force to act acts, and the elastic force (elastic coefficient) is set to a predetermined value. That is, the expiratory force required to stretch the telescopic body 2 becomes an appropriate value set according to the purpose of use, in other words, the force (expired air pressure) for blowing air from the mouth blowing body 5 is an appropriate value ( If it is not greater than or equal to (predetermined value), the elastic force is set to a predetermined value so that the stretchable body 2 does not stretch.

  Here, when one linear body 3 cannot accurately obtain a predetermined elastic force, or when a plurality of linear bodies 3 can obtain a predetermined elastic force more accurately and easily, A linear body 3 is provided. In other words, the plurality of linear bodies 3 are arranged so that the stretchable body 2 does not extend unless the force for blowing air from the mouth blowing body 5 is equal to or greater than an appropriate value (predetermined value). Such a linear body 3 is accommodated and disposed in the stretchable body 2 on the inner ring side where the stretchable body 2 is wound in a spiral shape.

  The exclusive pipe body 4 is a substantially cylindrical shape, and is an exclusive pipe section in which one end 41 side is coaxially connected to the one end 21 of the stretchable body 2. That is, as shown in FIG. 4, a cylindrical body made of a thick paper material having a predetermined material is inserted into one end 21 of the stretchable body 2, and the one end 41 side of the special tube 4 is inserted into one end of the stretchable body 2. The edge 21a reaches the vicinity of the other end portion 42 (mouth blowing body 5) of the exclusive pipe body 4. In other words, in this embodiment, the one end 41 side of the special tube 4 is inserted long into the one end 21 of the expansion / contraction body 2, whereby the one end 21 side of the expansion / contraction body 2 is long supported by the special tube 4. The stretchable body 2 extends straightly. The inner diameter and the length of the special tube 4 are set so that the user can easily have the air and the blower 5 can easily blow air into the stretchable body 2.

  The blow-back support 6 is a long body having a substantially U-shaped cross section, and extends and projects from the one end 41 of the special tube 4 with the one end 61 connected to the special tube 4, and the stretchable body 2 extends. In this state, the elastic body 2 is formed so as to accommodate and support the one end 21 side and guide the elastic body 2 to the side of the exclusive pipe 4 when the elastic body 2 is wound.

  Specifically, as shown in FIGS. 3 and 6, a long body having a substantially U-shaped cross section, and one end portion 61 of the blow-back support 6 is connected to the main tube 4 together with the stretchable body 2. Yes. That is, as shown in FIG. 2, the one end 61 is located on one end edge 21 a of the elastic body 2, and the connection tape 7 is attached so as to cover the one end edge 21 a of the elastic body 2 over the entire circumference. One end 21 of the body 2 and one end 61 of the blow-back support 6 are connected to the special tube 4.

  In such a connected state, the blow-back support 6 extends straightly from the one end 41 so as to be coaxial with the exclusive tube 4. Here, the length of the blowback support 6, that is, the protruding length L <b> 2 from the one end portion 41 of the exclusive pipe body 4 shown in FIG. 5 is based on the length L <b> 1 of the stretchable body 2. The elastic body 2 is set so as to support the one end 21 side (from the one end 21 to the center side) in a state so that the elastic body 2 does not hang down or bend and does not obstruct use or storage. ing.

  The cross-sectional shape (cross-sectional shape perpendicular to the longitudinal direction) of the blowback support 6 is formed so as to accommodate the one end 21 side of the stretchable body 2 in a state where the stretchable body 2 is stretched. That is, as shown in FIG. 6, the telescopic body 2 having a gutter-like cross section and a substantially circular cross section is accommodated, and the bottom 2 a of the telescopic body 2 is in contact with the bottom surface 6 a of the blow-back support 6. The both sides of the stretchable body 2 are formed so as to surround the sides 6b of the blow-back support 6.

  Furthermore, the cross-sectional shape of the blow-back support 6 is formed so as to guide the stretchable body 2 to the exclusive tube 4 side when the stretchable body 2 is wound. That is, as shown in FIG. 3, the spiral part 2A around which the expansion / contraction body 2 is wound is accommodated in the blowback support 6 and both side parts 2A1 of the spiral part 2A are blown back support 6. Is formed so as to be in contact with both side surface portions 6b (so that the spiral portion 2A is sandwiched between both side surface portions 6b of the blow-back support 6).

  As a result, as shown in FIG. 7, during the rewinding, the spiral portion 2 </ b> A (expandable body 2) is guided to the side of the special tube 4 by the blow-back support 6, and the axis of the expandable body 2 is the main tube 4. The stretchable body 2 is sequentially wound so as to coincide with the axial center of. As a result, the spiral portion 2A does not protrude laterally or loses its shape, and the stretchable body 2 is wound with the axial centers overlapping to form a spiral spring portion 2A as shown in FIG. And fit in the blow-back support 6.

  In the blowback 1 having such a configuration, when the user blows air from the mouth blower 5, as shown in FIG. 5, the air flows into the stretchable body 2, the stretchable body 2 extends, and the air is not blown. Then, as shown in FIGS. 1 and 2, the elastic body 2 is wound back into a spiral shape by the elastic force of the linear body 3. At this time, if the force (expired air pressure) for blowing air from the mouth blowing body 5 is not equal to or higher than the appropriate value (predetermined value) set according to the purpose of use, the stretchable body 2 does not continue to stretch, Accordingly, if the air amount set in advance is not blown, the stretchable body 2 does not extend over the entire length L1. Therefore, by repeating the expansion / contraction (blow-back) of the stretchable body 2 using such blowback 1, exercise and training can be performed with an appropriate blowing force according to the purpose of use.

  And in the state which the expansion-contraction body 2 extended, as shown in FIG. 5, when the support member 6 for blowing back accommodates and supports the one end part 21 side of the expansion-contraction body 2, and the expansion-contraction body 2 is wound, As shown in FIG. 7, the blowback support 6 guides the stretchable body 2 to the side of the special tube 4.

  As described above, according to the blowback 1, since the one end 21 side of the stretchable body 2 is accommodated and supported by the blowback support 6 in a state where the stretchable body 2 is stretched, the stretchable body 2 is long. Even so, it is possible to prevent / suppress the stretchable body 2 from hanging or bending. Further, when the stretchable body 2 is wound, the stretchable body 2 is guided to the side of the special tube 4 by the blow-back support 6, so even if the stretchable body 2 is long, the stretchable body 2 is properly ( It can be rolled up (without breaking the shape). In this way, even if the stretchable body 2 is long, proper use is possible, the appearance is good, a sense of accomplishment and a refreshing feeling can be felt, and deterioration of the stretchable body 2 can be suppressed.
