Description

  The present invention relates to an air massage apparatus that inflates and contracts an air bag by supplying and exhausting air to massage a treatment part of each part of the body.

There are many air massage devices that inflate and contract an air bag by supplying and exhausting air to massage a treatment part of each part of the body. In this type of air massage apparatus, a non-stretchable material is generally used as a material for the airbag. For example, as described in Patent Document 1, the airbag is composed of inner and outer two layers, and the inner layer material is made of polyurethane effective for preventing air leakage, and the outer layer material is effective for preventing excessive swelling. 6-nylon is used.
Thus, the reason for using a non-stretchable material for the entire airbag is that an effective massage cannot be performed when a stretchable material is used for the airbag. That is, when stretchable material is used, local force acts on the part of the airbag where the body treatment part is placed, but the body treatment part is in the air bag so that all the pressure is uniform. The part that is not placed stretches and swells, and the force that opposes the treatment area of the body is distributed to other parts, so that effective pressing force cannot be applied to the treatment area of the body, resulting in effective massage. It is because it becomes impossible to do.

  When using a strip-shaped air bag, it is also possible to use a stretchable material on one side and a non-stretchable material on the other facing surface with reference to the cushion structure described in Patent Document 2. It is done. However, since such a cushion structure is a structure that cannot be expanded in the thickness direction by the connecting yarn, the connecting yarn is omitted when used as an airbag. A schematic structure of a strip-shaped air bag having such a structure is shown in FIGS. 12 and 13 as a reference example. The airbag (bag part) 100 shown in FIGS. 12 and 13 has a structure in which an upper layer member 101 is formed of a stretchable material and a lower layer member 102 is formed of a non-stretchable material, and these members are hermetically sealed around the periphery. Is. FIG. 12 is a cross-sectional view of this reference example airbag in an inflated state, and FIG. 13 shows a state in which both leg portions as treatment portions are deformed on the airbag in the inflated state.

  In FIG. 13, concave portions 103 and 104 in the upper layer member 101 are portions where body weights such as legs serving as treatment portions are acting. As described above, when the upper layer member 101 is formed of a stretchable material, when a local force is applied to a portion made of the stretchable material, the leg portion 105 is placed in the same manner as the above-described operation. The non-stretched portion expands and swells, and the force facing the leg portion 105 is distributed to the other portions. As a result, an effective pressing force cannot be applied to the body treatment portion.

  For this reason, the conventional airbag for an air massage device is configured so that it can be pressed against the treatment portion with a desired force by suppressing the deformation due to the force acting from the treatment portion by comprising the whole with a non-stretchable material. It had been.

  In general, the air bag is exhausted by the pressure difference between the pressure inside the air bag and the atmosphere and the tension at which the air bag constituting material tends to contract. For this reason, since the pressure in the airbag at the start of the exhaust is high, the pressure inside the airbag is large, so that the exhaust is smoothly performed by the pressure difference between the pressure inside the airbag and the atmosphere without depending on the tension of the airbag. In addition, air bag exhaust after exhaust has progressed depends on the tension of the air bag because the pressure inside the air bag decreases and the pressure difference between the air bag interior and the atmosphere becomes smaller. Become.

  However, when the entire airbag is formed of a non-stretchable material as described above, the tension of the airbag is not so great. For this reason, the exhaust of the air bag after the exhaust has progressed is not smoothly performed, air remains in the air bag, and the air bag is not sufficiently contracted.

  The present invention has been made in order to solve the above-described problems of the prior art, and by effectively contracting the airbag, the airbag can be clearly inflated and contracted so that the massage effect can be achieved. It is an object to provide an air bag for an air massage device that improves the air quality and an air massage device that employs such an air bag.

  An airbag for an air massage device according to the present invention includes a bag portion formed of a non-stretchable material and an elastic member that acts to contract the inflated bag portion by an elastic force. To do.

  The bag portion is formed by stacking an upper layer member made of a non-stretchable material and a lower layer member made of a non-stretchable material and hermetically adhering at a peripheral portion, and the elastic member is formed on a lower surface of the lower layer member of the bag portion. An elastic member formed in a sheet shape or a plate shape disposed along the bag portion, and when the bag portion is inflated, the adhesive end portion of the bag portion is extended so that the two opposite end portions of the elastic member are extended. You may make it fix to.

  The elastic member has a sheath shape and is formed so that the bag portion is inserted from an opening on the sheath, and the bag portion is compressed from the outer peripheral surface by an elastic force in a state where the bag portion is expanded. You may make it form so.

  The elastic member is preferably made of a rubber material.

  Further, the bag portion is formed by stacking an upper layer member made of a non-stretchable material and a lower layer member made of a non-stretchable material and sealingly adhering at a peripheral portion, and the elastic member is in a state where the bag portion is inflated. The two adhesive end portions may be formed from springs attached between the two adhesive end portions facing each other of the bag portion and the peripheral mechanism portion so as to pull the two adhesive end portions from both sides.

  Moreover, the air massage apparatus according to the present invention uses the air bag.

  Since the airbag for an air massage device according to the present invention includes a bag portion formed of a non-stretchable material and an elastic member that acts to contract the expanded bag portion by elastic force, When the pressure becomes lower, the shrinkage of the bag part is promoted by the elastic force of the elastic member, and the bag part can be shrunk quickly. Further, when the pressure in the bag portion becomes low, residual air that has not been discharged due to the pressure difference between the bag portion and the atmosphere in the past can be discharged by the elastic force of the elastic member. The part can be shrunk.

  In addition, the bag portion is formed by stacking an upper layer member made of a non-stretchable material and a lower layer member made of a non-stretchable material and hermetically adhering at a peripheral portion, and the elastic member is formed on a lower surface of the lower layer member of the bag portion. An elastic member formed in a sheet shape or a plate shape arranged along the line, and when the bag portion is inflated, the adhesive end of the bag portion is stretched so that the two opposite ends of the elastic member extend. If it is made to fix to a part, when the pressure of a bag part falls, a sheet-like or plate-shaped elastic member will return to the state at the time of a bag part shrinkage | contraction. Therefore, the bag portion can be quickly and reliably contracted by the elastic force of the elastic member. Further, since the elastic member is fixed to the outer surface portion of the bag portion, it can be fixed to the bag portion by a simple means such as a hook.

  The elastic member has a sheath shape and is formed so that the bag portion is inserted from an opening on the sheath, and the bag portion is compressed from the outer peripheral surface by an elastic force in a state where the bag portion is expanded. If formed in such a manner, the contraction force of the elastic member on the bag portion increases. Therefore, when the pressure in the bag portion becomes low, the bag portion can be contracted faster and more reliably. In addition, when the pressure in the bag portion becomes low, residual air that has not been discharged due to the pressure difference between the bag portion pressure and the atmosphere can be discharged more reliably, and the bag portion can be more reliably contracted. Can be made. The elastic member can be easily attached by inserting the bag portion from both ends of the cylindrical elastic member.

  Further, when a rubber material is used as the elastic member, the shrinkage force of the bag portion can be improved at a low cost.

  Further, the bag portion is formed by stacking an upper layer member made of a non-stretchable material and a lower layer member made of a non-stretchable material and sealingly adhering at a peripheral portion, and the elastic member is in a state where the bag portion is inflated. When the pressure of the bag portion is reduced, the two adhesive end portions are pulled from both sides so that the bag portion is made of a spring attached between the two opposite adhesive end portions of the bag portion and the peripheral mechanism portion. Moreover, the elastic force which tries to return a bag part to a planar shape by an elastic member acts, a bag part can be shrink | contracted quickly, and a bag part can be shrink | contracted reliably.

  Moreover, since the air massage apparatus which concerns on this invention uses the said airbag, it can shrink an airbag reliably and can improve a massage effect.

  Hereinafter, each embodiment will be described with reference to the drawings.

An air massage apparatus according to a first embodiment embodying the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view of the air massage device according to the first embodiment, and FIG. 2 is a side view of the air massage device in use.

  As shown in FIGS. 1 and 2, the air massage apparatus according to the first embodiment includes a mat body 1, and a back airbag that is disposed on the mat body 1 so as to massage the back, which is a treatment part of the user X. 2. It is composed of a leg air bag 3, which is also arranged to massage the leg part, which is also a user's X treatment part, an air supply / exhaust device 4 for supplying and exhausting air to and from the air bags 2, 3. .

  The mat body 1 is formed in a thick rectangular shape as a body support. On the foot side of the mat body 1, a pipe connection portion 5 with the air supply / exhaust device 4 is formed.

  The back airbag 2 is composed of four strip-shaped airbags 6, and the leg airbag 3 is also composed of four strip-shaped airbags 7. The airbags 6 and 7 are flat rectangles when contracted, and are arranged on the mat body 1 in parallel so that the longitudinal direction thereof is the lateral direction of the body. Further, the air bags 6 and 7 are connected to the air supply / exhaust device 4 via the pipe connection portion 5 by air pipes embedded in the mat body 1.

  The air supply / exhaust device 4 supplies air to the air bags 6, 7 or exhausts air from the air bags 6, 7, and controls the air pump and supply / exhaust of each air bag 6, 7. The air piping path part such as a switching valve is accommodated.

  Next, a specific structural example of the airbags 6 and 7 will be described with reference to FIGS. 3 is a perspective view in the contracted state of the airbag used in the air massage device, FIG. 4 is a sectional view in the contracted state of the airbag, FIG. 5 is a sectional view in the expanded state of the airbag, FIG. 6 is a perspective view of the airbag in an inflated state. In these figures, the air bag 6 will be described as an example, but the air bag 7 also has the same structure as the air bag 6.

The air bag 6 includes a bag portion 10 and an elastic member 15. Moreover, the bag part 10 is comprised from the sheet-like or cloth-like upper layer member 11 and lower layer member 12 which consist of non-stretchable members, such as nylon, polyethylene reinforced with nylon taffeta, and cloth. Moreover, as shown in FIG. 4, the bag part 10 has the upper layer member 11 and the lower layer member 12 piled up, and these members 11, 12 are hermetically bonded at the peripheral part. The elastic member 15 has a sheet shape or a plate shape, and is fixed along the outside of the lower layer member 12 of the bag portion 10. As the elastic member 15, a rubber plate, an elastic resin plate, a spring or the like is used. The spring includes a leaf spring, a coil spring, a wire spring, a wire spring, a spring, and the like.
The elastic member 15 is fixed so that the bag portion 10 is contracted by an elastic force when the bag portion 10 is expanded. As a specific fixing method, for example, button type hooks 16 are attached to two opposing ends of the elastic member 15. A hook hole 14 into which the hook 16 is inserted is provided in the adhesive end portion 13 of the bag portion 10. Then, as shown in FIG. 4, the end of the elastic member 15 is fixed in a state where no tension is applied to the bonded end 13 of the contracted bag portion 10 by the engagement between the hook 16 and the hook hole 14.

In this way, when the bag portion 10 is inflated as shown in FIGS. 5 and 6, the central portion of the bag portion 10 is inflated, so that an elastic force is generated by the deformation of the elastic member 15. This elastic force acts to contract the bag portion 10.

  Accordingly, the airbag 6 includes the bag portion 10 formed of a non-stretchable material and the elastic member 15 that acts to shrink the bag portion by elastic force. When the temperature becomes low, the elastic force of the elastic member 15 promotes the shrinkage of the bag portion 10 and the bag portion 10 can be quickly shrunk. Further, when the pressure in the bag portion 10 becomes low, residual air that has not been discharged due to the pressure difference between the pressure in the bag portion 10 and the atmosphere in the past can be discharged by the elastic force of the elastic member 15. The bag portion can be contracted more reliably.

  Further, the sheet-like or plate-like elastic member 15 is disposed along the lower surface of the bag portion 10 made of a non-stretchable material, and the end portion of the elastic member 15 can be deformed when the bag portion 10 is expanded. Thus, since it is being fixed to the adhesion end part 13 of the bag part 10, when the pressure of the bag part 10 falls, the elastic member 15 tries to return to the shape at the time of the contraction state of the bag part 10. FIG. Therefore, the bag portion 10 can be quickly and reliably contracted by the elastic force of the elastic member 15. Further, since the elastic member 15 is fixed to the outer surface portion of the bag portion 10, it can be fixed to the bag portion 10 by simple means such as a hook 16.

  In addition, when a rubber material is used as the elastic member 15, the cost can be reduced and the contraction force of the bag portion 10 can be improved.
