  By the way, in the structure of the expansion / contraction bag as in Prior Art Document 1, a plurality of expansion / contraction portions on the left and right can be expanded / contracted at the same time by a single air supply / exhaust port portion and air hose. A problem arises when the inflatable bag is curved so as to follow the shape of the part. That is, as shown in FIG. 20, when the inflatable bag 20 is curved and deformed so as to conform to the shape of the treatment portion 2 that is concave, and the left and right inflatable portions 27 and 27 are provided so as to face each other, The non-inflatable portion 26 is formed so as to be located in the middle of the inflatable bag 20 in a side view, and the wall surface 35 of the ventilation portion 20c is located closer to the human body treatment site M than the non-inflatable portion 26. As a result of the bending deformation, the force concentrates on the wall surface 35 to cause bending. As a result, it has been considered that the internal space of the ventilation portion 20c is narrowed and the ventilation to the expansion / contraction portions 27 and 27 is deteriorated.

  In addition, such a problem can be solved by connecting an air hose to each expansion / contraction part as in Prior Art Document 2, but the number of air hoses corresponding to the number of expansion / contraction parts There is a problem that it complicates the piping and installation work of the air hose.

  Accordingly, the present invention has been made to solve the above-described problems, and is provided in a treatment section for treating a human body treatment site provided at an appropriate position of an air massage machine, and a single air supply / exhaust A plurality of expansion / contraction portions can be expanded / contracted by the mouth portion and the air hose, and even if it is deformed so as to follow the shape of the treatment portion that is bent or bent, the bending generated in the ventilation portion is made as much as possible. An object of the present invention is to provide an inflatable bag that can secure the internal space of the ventilation part by suppressing it.

That is, the expansion / contraction bag of the present invention is disposed in a treatment section for treating a human body treatment site provided at an appropriate position of an air massage machine equipped with an air supply / exhaust device for supplying and exhausting air, and air supply / discharge A single air supply / exhaust port portion for coupling with the tip of an air hose connected to the apparatus, an expansion / contraction portion that repeatedly expands and contracts by air supply / exhaust, and an air supply / exhaust port portion and an expansion / contraction portion And a tubular non-expandable portion that is integrally formed with the vent portion in the length direction of the vent portion and has no internal space and is non-expandable. A non-inflatable / deflated portion is integrally formed on the wall surface of the ventilation portion on the human body treatment site side, and the length direction of the ventilation portion is on the wall surface of the ventilation portion opposite to the human body treatment portion side. In FIG. 1, convex bulges bulging in a convex shape in cross section are continuously formed.

  In addition, the inflatable bag of the present invention is arranged in the treatment part, which allows the treatment part to sandwich and treat a human body treatment part, and includes a plurality of the inflate / deflection parts. The contracted portions are formed so as to face each other.

  Therefore, the inflatable bag of the present invention is formed by integrally forming the non-inflatable portion on the wall surface of the ventilation portion on the human body treatment site side, so that the inflatable bag is bent or bent along the shape of the treatment portion. Even if it is deformed, the wall of the ventilation part on the side of the human body treatment site where the force tends to be concentrated due to the force is reinforced by the non-expanded part, so that the internal space of the ventilation part is narrowed by the bending and the ventilation deteriorates Can be prevented as much as possible, and the internal space of the ventilation part can be always maintained.

  Further, the inflatable bag according to the present invention is disposed in a treatment part that allows the treatment part to perform treatment while sandwiching a human body treatment site, and is provided with a plurality of the inflate / deflate parts, and the inflated / deflated part is inflated Since these are formed so as to face each other, in such a treatment part, it is possible to carry out an effective pinching massage by the opposing expansion / contraction part.

  Further, the inflatable bag according to the present invention is formed by continuously forming a convex raised portion that protrudes in a convex shape in a sectional view in the length direction of the ventilation portion on the wall surface of the ventilation portion opposite to the human body treatment site side. Therefore, when the ventilation part is curved, the wall surface of the ventilation part on the human body treatment site side is reinforced by the non-expanded part, so that the wall surface of the ventilation part opposite to the human body treatment site side is expanded and ventilated. The internal space of the part is slightly reduced, but the reduced space is compensated by forming a convex raised part, and it is possible to prevent the deformation due to the expansion of the wall surface of the ventilation part as much as possible. it can.

Below, the expansion / contraction bag of this invention is demonstrated in detail based on one Embodiment shown in drawing.

FIG. 13 is a cross-sectional explanatory view showing an embodiment of the expansion / contraction operation of the expansion / contraction bag of the present invention, and FIG. 14 is a perspective view showing an embodiment in which the expansion / contraction bag of the present invention is disposed in an air massage machine. FIG. 15 is a perspective view showing one embodiment of a use state. 16 to 20 are reference diagrams showing the prior art.

  That is, the inflatable bag 3a of the present invention shown in FIG. 1 and FIG. 4 is disposed in the treatment part 2a for treating a human body treatment site provided at an appropriate position of the chair type air massage machine 1a as shown in FIG. And it is used in order to treat a human body treatment site | part, and it forms by three-dimensional shaping | molding, such as blow molding, using soft resin as a material.

  The inflatable bag 3a is provided in the lower space of the seat portion 11a of the air massage machine 1a, and is supplied with air from an air supply / discharge device 4a provided with a power source for supplying and exhausting air through an air hose 5a. The expansion / contraction part 33a is provided so as to perform expansion / contraction operation by repeating expansion and contraction by exhaust.

  As shown in FIG. 5, the expansion / contraction part 33a has a continuous uneven shape in a cross-sectional view. Therefore, when expanding, this uneven shape expands and becomes larger than the volume when not expanded, so that the degree of expansion can be increased by forming this uneven shape. When the expansion / contraction part 33a expands, the human body treatment site M is pressed, and a pressure massage is performed by repeating the expansion / contraction operation.

  As shown in FIG. 1, the air hose 5a connected to the air supply / exhaust device 4a is connected to a single supply / exhaust port 31a provided at the appropriate position of the expansion / contraction bag 3a at the other end, as shown in FIG. is doing. The tip of the air hose 5a and the air supply / exhaust port portion 31a may be connected via a connection connecting part (not shown), and the connection connection part is attached to the air massage machine 1a of the inflatable bag 3a. Depending on the situation, it may be deformable or may be deformed.

  Further, a tubular ventilation portion 32a is provided for allowing the supply / exhaust port portion 31a and the expansion / contraction portion 33a to vent each other so that air is supplied from the supply / exhaust port portion 31a to the expansion / contraction portion 33a.

  Further, in the longitudinal direction of the ventilation portion 32a, it is formed integrally with the ventilation portion 32a, and is not affected by air supply / exhaust, and does not have an internal space, and is a non-expanded planar non-expandable A portion 34a is formed.

  A fixing hole 37a for fixing the expansion / contraction bag 3a to the treatment portion 2a is formed at an appropriate position of the non-expandable portion 34a, and a fixing member such as a screw is provided as shown in FIG. 38a is fastened so that the fastening direction is on the human body treatment site M side.

  FIG. 8 shows another form of fastening method, in which a fastening recess for the fastening member 38a is provided in the non-expanded part 34a, and the fastening direction is opposite to the human body treatment site M side. It's so fast.

  As shown in FIG. 5, the expansion / contraction bag 3a of the present invention having the above-described configuration integrally forms the non-expansion / contraction part 34a on the wall surface 35a of the ventilation part 32a on the human body treatment site M side. I have to.

  With this configuration, as shown in FIG. 9, even if the inflatable bag 3a is deformed and attached so as to conform to the shape of the treatment portion 2a that is not flat and curved or bent, the force tends to be concentrated and bend easily. Since the wall surface 35a is reinforced by the non-expandable portion 34a, the internal space of the ventilation portion 32a can be always secured.

  Furthermore, the structure of the expansion / contraction bag 3a of the present invention shown in FIG. 2 is such that the ventilation portion 32a and the non-expansion / contraction portion 34a are formed between the expansion / contraction portions 33a, 33a provided as a pair of left and right. is there.

  The inflatable bag 3a by this structure can be used, for example, when the treatment part 2a of the air massage machine 1a can perform treatment by holding the human body treatment site M. That is, as shown in FIG. 10, in a state where the non-expandable part 34a formed at the center of the inflatable bag 3a is fixed to the surface of the treatment part 2a having a flat shape by the fixing member 38a, When the expansion / contraction part 33a / 33a is inflated, the expansion / contraction part 33a / 33a expands in a direction opposite to each other. A pinching massage can be performed. Along with this expansion / contraction operation, the ventilation portion 32a is slightly curved, but as described above, the wall surface 35a of the ventilation portion 32a on the human body treatment site M side where the force is concentrated and the bending is likely to occur. It is reinforced by the non-expanded portion 34a.

  In addition, in the case of a substantially L-shaped treatment part 2a shown in FIG. 11, the inflatable bag 3a is bent and attached so that the inflatable parts 33a and 33a are located on the wall surfaces 21a and 21a, respectively. Although the expansion / contraction operation is performed, the expansion / contraction portions 33a and 33a expand in directions opposite to each other, so that the human body treatment site M is clamped by repeating the expansion / contraction operation, thereby effectively performing a pressure massage. Can be done. Since this treatment part 2a is formed in a substantially L shape, the pressure massage effect can be enhanced more than the treatment part having the flat shape described above.

  Furthermore, as shown in FIG. 12, in the case of the concave treatment part 2a, the expansion / contraction bag 3a is attached so that the expansion / contraction part 33a / 33a is located on the wall surfaces 21a / 21a facing each other, and the expansion / contraction operation is performed. By performing, it is possible to carry out a pinching massage having a higher pinching property than a substantially L-shaped treatment part.

  Even if the inflating / deflating bag 3a is deformed so as to conform to the shape of the approximately L-shaped or concave treatment portion 2a, the vent portion 32a is not bent by the non-inflating / deflating portion 34a as described above.

  In the concave treatment portion 2a, as shown in FIG. 13, the expansion / contraction portions 33a and 33a are positioned on the opposing wall surfaces 21a and 21a, respectively, and the bottom surface 22a at the bottom of the treatment portion 2a is also inflated. It is also possible to form the inflatable bag 3a so that the contracted portion 33a is located. These three expansion / contraction bags 3a communicate with each other through the ventilation portion 32a. Although not shown, the single air supply / exhaust port portion 31a is provided so as to ventilate the ventilation portion 32a at an appropriate position. When these inflatable and inflatable bags 3a are inflated, they inflate in directions opposite to each other, so that an effective squeezing massage over the peripheral part of the human body treatment site M can be performed by repeating the inflating and deflating operations.

  In addition, as shown in FIGS. 3 and 6, the inflatable bag 3a of the present invention has a length of the vent portion 32a on the wall surface 35a of the vent portion 32a opposite to the human body treatment site side of the inflatable portion 33a. Convex bulges 36a that bulge in a cross-sectional convex shape in the direction are continuously formed. The convex raised portion 36a has an internal space and is assimilated with the internal space of the ventilation portion 32a.

  When the expansion / contraction bag 3a formed with the convex raised portion 36a is deformed so as to conform to the shape of the treatment portion such as a curved or bent shape, the wall surface 35a of the ventilation portion 32a on the human body treatment site side is not inflated / contracted Since it is reinforced by the part 34a, the wall surface 35a of the ventilation part 32a opposite to the human body treatment site side of the expansion / contraction part 33a extends to slightly reduce the internal space of the ventilation part 32a. For example, as shown in FIG. 11, when comparing the linear straight vent portion width W1 of the bent expansion / contraction bag 3a with the curved vent portion width W2 that is bent and deformed, the curved vent passage is larger than the straight vent portion width W1. The portion width W2 is slightly smaller, and accordingly the internal space of the curved ventilation portion 32a is reduced, and the air permeability is slightly lowered.

  However, a decrease in the internal space of the ventilation portion 32a can be compensated by the internal space of the convex raised portion 36a. Furthermore, it is possible to prevent the deformation of the wall due to the expansion of the wall surface of the ventilation portion 32a as much as possible.
