Description

TECHNICAL FIELD The present invention relates to a blowback, and more particularly to a blowback that can be used for purposes such as health promotion, treatment, and beauty.

Blowbacks have long been known as blowback toys. In this blowback, a linear spring material is arranged along the longitudinal direction of a cylindrical expandable body (bag-shaped part), and when air is blown from one end of the expandable body, the expandable body stretches and air is not blown. In this state, the stretchable body is spirally wound by the elastic force of the spring material.

Such blowbacks have conventionally been used mainly as toys for children, but blowbacks that can be used for purposes such as health promotion, treatment, and beauty are known (see, for example, Patent Document 1). . This blowback can maintain good sanitary conditions even after repeated use over a long period of time by detachably attaching a mouthpiece made of an antibacterial soft material to the blowing part.

Utility Model Registration No. 3137944

By the way, a metal wire having a circular (round) cross section has been used as a conventional spring material. For this reason, the conventional blowback has a low durability and deteriorates due to repeated use, and there are cases where it cannot be used properly. In other words, the elasticity of the spring material deteriorates due to repeated expansion and contraction of the stretchable body and the spring material, and the stretchable body may not be wound back into a spiral shape properly.

As a result, it becomes impossible to stretch the stretchable body with the appropriate predetermined expiratory force (exhale force) and expiratory volume (exhale volume), and the exercise effect (health promotion effect, beauty improvement effect, etc.) by using the blowback is reduced. There was a possibility that it could not be obtained properly. In particular, under the recent epidemic of the new corona, people are often indoors, and therefore, the frequency of using blowbacks that allow them to exercise indoors is increasing, so it is possible to use blowbacks properly for a longer period of time. is desired.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a blow-back that can be properly used for a longer period of time.

In order to solve the above-mentioned problems, the invention of claim 1 provides a cylindrical and deformable extensible body, a linear body having elasticity and arranged along the longitudinal direction of the extensible body, and a cylindrical body. a mouthpiece connected to one end of the extensible body, and a tubular mouth-blowing body connected to the opposite end of the extensible body of the extensible body and into which a user blows air by holding the mouthpiece in one's mouth; When air is blown into the extensible body, the extensible body is stretched, and in a state where air is not blown, the extensible body is spirally wound by the elastic force of the linear body, and the cross section of the linear body is horizontally long. and the linear body is arranged so that the lateral surface is along the stretchable body.

The invention of claim 2 is characterized in that, in the blowback of claim 1, the cross section of the linear body has a shape obtained by crushing a circle from above and below.

According to the first aspect of the present invention, the linear body has a laterally long cross section and the linear body is disposed so that the lateral surface follows the expandable body, so that it can be used properly for a longer period of time. . That is, since the linear body with a laterally long cross section is arranged along the longitudinal direction of the elastic body with the horizontal surface along the elastic body, the durability and stability are improved, and it can continue to be used like a spiral spring. Extends and rewinds stably. Therefore, even if the extensible body and the linear body are repeatedly stretched and contracted, the linear body is less likely to weaken and deteriorate, and can be used stably and appropriately for a longer period of time.

For example, according to experiments conducted by the inventors of the present application, when used (expanded and contracted) several times a day, the conventional blowback with a circular cross section of the linear body deteriorates in a few days. Therefore, it was confirmed that this blowback does not deteriorate even after one week of use (it stably stretches into an appropriate shape and rolls back). Since the durability and stability are improved in this way, the elastic body can be repeatedly expanded and contracted with an appropriate predetermined expiratory force and expiratory volume, and the exercise effect (health promotion effect and beauty effect) by using blowback can be achieved. improvement effect, etc.) can be properly maintained for a long time.

Moreover, since the cross section of the linear body may be oblong, it is possible to extend the blowback life easily and at low cost. In addition, since the cross section of the linear body is oblong, even if the user touches the tip of the linear body, it is possible to reduce injury to the user and improve safety.

According to the second aspect of the invention, since the cross section of the linear body has a simple shape in which a circle is crushed from above and below, the linear body and blowback can be manufactured easily and at low cost. becomes possible. For example, a linear body can be manufactured by simply crushing a wire having a circular cross section from above and below.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the illustrated embodiments.

1 and 2 are a plan view and a front view showing a contracted state of the expandable body 2 of the blowback 1 according to the embodiment of the present invention. This blowback 1 is a blowback that can be used particularly for purposes such as health promotion, treatment, and beauty. Prepare.

The stretchable body 2 is a cylindrical and deformable bag-shaped part, and is made of paper or the like having materials (characteristics) such as predetermined thickness, strength, density (weight per unit area), and durability. It is As shown in FIG. 3, the extensible body 2 is set to have a substantially circular cross section and an inner diameter slightly larger than the outer diameter of the exclusive tube body 4 when inflated by blowing air. As will be described later, such a stretchable body 2 is formed into a tubular shape by bending a substantially rectangular sheet-like first material 21 .

In addition, the length of the extensible body 2 (length excluding the portion where the exclusive tube 4 is inserted) is determined according to the purpose of use of the blowback 1 such as health promotion, treatment, beauty, etc., and the functional state of the oral cavity and physical condition of the user. It is set according to the user's situation. That is, the length of the extensible body 2 is set so that the amount of air/exhalation required to extend the extensible body 2 over the entire length is an appropriate amount of air that is preset according to the purpose of use, the user's situation, and the like. ing.

The linear body 3 is a wire/spring material having elasticity and arranged straight along the longitudinal direction of the elastic body 2 . That is, it is made of stainless steel wire, and when no external force is applied (no air is blown into the extensible body 2), it is wound in a spiral/coil shape, and when it is stretched straight and the external force is released, it returns to a spiral shape. An elastic force acts thereon, and its elastic force and elastic modulus are set to predetermined values. That is, the expiratory force required to extend the extensible body 2 becomes an appropriate value set according to the purpose of use and the user's situation.・The elastic force is set to a predetermined value so that the extensible body 2 does not expand unless the expiratory pressure is equal to or greater than an appropriate value (predetermined value).

Here, for example, even if the purpose is to promote health, different appropriate values such as level 0, level 1, and level 2 are set in descending order according to the oral function state, physical condition, age, etc. of the user. Sometimes. In other words, the appropriate value of the blowing force (expiratory pressure) is finely set according to the purpose of use and the user's condition.

In addition, when the elastic force of a predetermined value cannot be obtained accurately with one linear body 3, or when the elastic force of a predetermined value can be obtained more accurately and easily with a plurality of linear bodies 3, a plurality of linear bodies 3 are used. A shaped body 3 is arranged. That is, by arranging a plurality of linear bodies 3, the expandable body 2 does not expand unless the force for blowing air from the mouthpiece 5 is equal to or greater than an appropriate value (predetermined value). For example, one linear body 3 having a predetermined elastic force is provided for level 1, and two linear bodies 3 having the same predetermined elastic force are provided for level 2. ing.

As shown in FIG. 4, the linear body 3 has a cross-sectional shape (a cross-sectional shape perpendicular to the longitudinal direction) of a horizontally long shape (horizontally long flat shape, substantially rectangular). Specifically, it has a cross-sectional shape obtained by crushing a circle from above and below. That is, a wire/wire material 30 having a substantially circular cross section as shown in FIG. It extends horizontally in parallel, and the left and right vertical surfaces 32 are arcuate. Due to such a cross-sectional shape, the linear body 3 is formed in an elongated band shape (a spiral spring shape) as a whole. In addition, with this cross-sectional shape, the above elastic force and elastic modulus can be obtained.

The linear body 3 is accommodated and arranged in the elastic body 2 so that the lateral surface 31 is along the elastic body 2 on the inner ring side around which the elastic body 2 is spirally wound. That is, as shown in FIG. 4, the stretchable body 2 is composed of a substantially rectangular first material 21 and a strip-shaped second material 22, and the one end 21a of the first material 21 is located on the upper side. Furthermore, one end portion 21a and the other end portion 21b are overlapped to form a tubular shape. Then, the second material 22 is placed on the surface side (outer side) of the overlapping portion 21c where the one end portion 21a and the other end portion 21b are overlapped so that the linear body 3 is arranged along the horizontal surface 31. By bonding and connecting to the first material 21 so as to cover the entire surface of the portion 21c, the linear body 3 is arranged integrally with the stretchable body 2. As shown in FIG.

Thus, the linear body 3 is arranged on the overlapping portion 21c between the one end portion 21a and the other end portion 21b of the first material 21, and the second material 22 is arranged from above the linear body 3. Therefore, the linear body 3 is firmly sandwiched and held between the two materials 21 and 22 . As a result, the linear body 3 is firmly integrated with the stretchable body 2 . Here, although FIG. 4 shows a case where one linear body 3 is arranged, the number of linear bodies 3 to be arranged is set as described above.

The exclusive tube 4 is a tubular portion connected to one end of the extensible body 2 . 6, one end of the cylindrical body is inserted into one end of the expandable body 2, and the vinyl tape 6 is formed as shown in FIG. etc. are connected. The inner diameter and length of the exclusive tube body 4 are set so that the user can easily hold it and blow air from the mouth blower body 5 to the expandable body 2 easily.

The mouthpiece 5 is cylindrical and is connected to the end (the other end) of the exclusive tube 4 on the side opposite to the stretchable body 2, and is a mouthpiece that the user holds in his/her mouth and blows air into. That is, it is made of resin and, as shown in FIG. 7, includes a first trunk portion 51, a second trunk portion 52 and a third trunk portion 53.・The free end side has a slightly narrow cylindrical shape (cylindrical body in the shape of a truncated cone). The second trunk portion 52 is provided on the other end side of the first trunk portion 51 and has an inner diameter and an outer diameter set slightly larger than those of the first trunk portion 51 . The third trunk portion 53 is provided on the side of the second trunk portion 52 opposite to the first trunk portion 51 , and has an inner diameter and an outer diameter set slightly larger than those of the second trunk portion 52 .

The mouthpiece 5 is connected to the exclusive tube 4 by inserting and press-fitting the other end of the exclusive tube 4 into the third body 53 . At this time, the other end edge of the exclusive tube 4 contacts the inner stepped portion 531 of the third body portion 53 (the inner stepped portion formed by the second body portion 52 and the third body portion 53). Such a mouthpiece 5 is antibacterially processed so that it can be kept in good sanitary condition even after repeated use for a long period of time. Therefore, for example, when the extensible body 2 deteriorates, the mouthpiece 5 is removed from the exclusive tube 4 and attached to a new exclusive tube 4 with the extensible body 2 attached. can also be reused.

In the blowback 1 having such a structure, when the user blows air from the mouth blower 5, as shown in FIG. Then, as shown in FIGS. 1 and 2, the elastic force of the linear body 3 causes the elastic body 2 to spirally unwind. At this time, unless the force (expiratory force/expiratory pressure) for blowing air from the mouthpiece 5 is equal to or greater than an appropriate value (predetermined value) set according to the purpose of use and the user's situation, the expandable body 2 continues to expand. In addition, the telescopic body 2 does not extend over its entire length unless a predetermined amount of air is blown in according to the purpose of use and the user's situation. Therefore, by repeating the expansion and contraction (blowback) of the extensible body 2 using such a blowback 1, exercise and training can be performed with appropriate expiratory force and expiratory volume according to the purpose of use and the user's situation. It is.

As described above, according to the blowback 1, the cross section of the linear body 3 is oblong, and the linear body 3 is disposed so that the lateral surface 31 is along the telescopic body 2. can be used for That is, since the linear body 3 having a laterally elongated cross section is disposed along the telescopic body 2 with the lateral surface 31 along the longitudinal direction of the telescopic body 2, the durability and stability are improved, and the mainspring spring is improved. Extends and rewinds continuously and stably. Therefore, even if the extensible body 2 and the linear body 3 are repeatedly stretched and contracted, the linear body 3 is less likely to sag and deteriorate, and can be used stably and appropriately for a longer period of time.

For example, according to experiments conducted by the inventors of the present application, when used (expanded and contracted) several times a day, the conventional blowback with a circular cross section of the linear body deteriorates in a few days. Therefore, it was confirmed that the blowback 1 does not deteriorate even after one week of use (it stably stretches into an appropriate shape and rolls back). Since the durability and stability are improved in this way, the extensible body 2 can be repeatedly expanded and contracted with an appropriate predetermined expiratory force and expiratory volume, and the exercise effect (health promotion effect) by using the blowback 1 and beauty improvement effect) can be properly maintained for a long time.

Moreover, since the cross section of the linear body 3 may be oblong, it is possible to extend the life of the blowback 1 easily and at low cost. In addition, since the cross section of the linear body 3 is horizontally long, even if the user touches the tip of the linear body 3, it is possible to reduce injury to the user and improve safety. do.

Furthermore, since the cross section of the linear body 3 has a simple shape in which a circle is crushed from above and below, the linear body 3 and the blowback 1 can be manufactured easily and at low cost. . For example, the linear body 3 can be manufactured simply by crushing the wire rod 30 having a circular cross section from above and below.

In addition, it is possible to manufacture a plurality of linear bodies 3 having different elastic forces and elastic moduli, that is, a plurality of blowbacks 1 having different required exhalation forces, using one type of wire/wire material 30 having a circular cross section. becomes. That is, without using a plurality of wire rods 30 having different outer diameters, the wire rod 30 can be simply crushed from above and below to manufacture the linear body 3 and the blowback 1 having different elastic force and required expiratory force from the wire rod 30 as it is. This allows greater manufacturing flexibility. In addition, a plurality of linear bodies 3 and blowbacks 1 having different elastic forces and required expiratory forces can be manufactured only by changing the amount of crushing of the wire 30 from above and below (the height between the lateral surfaces 31 of the linear body 3). and improve convenience and flexibility.

Although the embodiments of the present invention have been described above, the specific configuration is not limited to the above-described embodiments. Included in the invention. For example, in the above-described embodiment, one expansion/contraction body 2 is provided for one exclusive tube 4, but depending on the purpose of blowback 1 and the user's situation, one exclusive tube 4 may be A plurality of elastic bodies 2 may be provided.

Moreover, although the case where the exclusive tube body 4 and the mouthpiece body 5 are separate bodies has been described, the exclusive tube body 4 and the mouthpiece body 5 may be integrally provided. Further, the extensible body 2 may be marked with a scale so that how much the extensible body 2 can be stretched can be easily confirmed visually.
