Description

  The present invention relates to an air bag of an air massage device.

  For example, as an air massage device, an air bag is placed on a band that wraps around a foot or arm, and compressed air is introduced into the air bag while the band is wound. Some use a band with an air bag to add. In particular, as an air massage device for the legs, the left and right air chambers are divided into air bags so that the leg muscles can be sandwiched from the left and right, and the left and right air chambers sandwiching the muscles are communicated with each other through the communicating portion. There are some (see, for example, Patent Document 1).

  Moreover, although it is not an air bag for an air massage device, a partition wall is formed on the inner side of the peripheral joint part of the rectangular flat bag body as an air bag to be arranged on the cuff belt of the wrist sphygmomanometer. There is one that is divided into a plurality of air chambers and in which the air chambers communicate with each other at a communication portion (see, for example, Patent Document 2).

JP 2000-237344 A Japanese Unexamined Patent Publication No. 64-72726

  By the way, the air bag used for an air massage apparatus brings about a massage action by repeatedly performing pressurization and depressurization, and at the time of pressurization, it is necessary to quickly apply a compression force to the muscle without waste. In particular, in the case of a simple and compact massage device, it is assumed that it is driven by a small battery, so if there is waste of pressure, an effective massage action cannot be given, and the battery will be exhausted accidentally. It may end up.

  In addition, since the pressure is repeatedly applied to the muscle while the band is wound, it is necessary to avoid giving pain to the skin and the muscle depending on the way of the compression.

  In this regard, for example, when massaging a leg calf with the air bag described in Patent Document 1, since the muscles are sandwiched from the left and right, a great massage effect can be expected, but the muscles are pressed only from the left and right sides, so the calf is strong Can be pinched and painful. In addition, since the legs and arms are usually narrower as you go forward, if the air bag does not fit, the air bag hits the thin part and the massage effect is comfortable. It may not be possible.

  Moreover, since the air bag described in Patent Document 2 has a partition wall and divides the air chamber into a plurality of parts, it is for a cuff band of a wrist type sphygmomanometer. When considered, there is still technical insufficiency in terms of effectively transmitting pressure to muscles and removing pressure without waste. Especially assuming that it is applied to a simple air massage device, batteries are mischievous. Can end up exhausting.

  In view of the above circumstances, an object of the present invention is to provide an air bag of an air massage device that can effectively transmit a compression force to muscles without causing pain and without giving pain.

  According to the first aspect of the present invention, in the air bag of the air massage apparatus which is arranged in a band wound around the foot or arm and applies pressure and release to the foot or arm by introducing and discharging pressurized air, It is formed as a flat bag body, and a partition wall is provided inside the peripheral joint part, so that the internal space is partitioned into a plurality of air chambers, and between the partition wall and the peripheral joint part or between the partition wall and the partition wall. A non-partitioned portion is left between the air chambers so as to communicate with each other. As the plurality of air chambers, a pair of left and right large-area pinching main bodies sandwiching a muscle portion from the left and right It is arranged between the air chamber and the pair of left and right main air chambers for reducing the area of the main air chamber to reduce the local pressure by the pair of left and right main air chambers for holding the muscle part. A pair of left and right air pressure chambers The partition wall forming the boundary between the main air chamber and the relaxation sub air chamber changes in width from a narrow width to a gradually wide width in the direction perpendicular to the left and right directions. Thus, the air bag is formed obliquely with respect to the center line in the left-right direction.

  The invention according to claim 2 is a flat, rectangular shape in which the peripheral edge is joined in an air bag of an air massage device that is arranged in a band wound around the toe and that compresses and releases the toe by introducing and discharging pressurized air.

  According to the first aspect of the present invention, a pair of left and right main air chambers for clamping are provided by partitioning the muscle portion from the left and right by partitioning the air bag disposed on the band wound around the legs and arms with the partition wall. In the middle of these main air chambers, there is a small area relief air chamber that relieves and reduces local compression by the main air chamber.For example, when massaging a calf, the introduction of pressurized air When the main air chamber of the area expands greatly, pressing force can be applied to the calf mainly from the left and right sides. In addition, because the auxiliary air chamber presses the back side of the calf, it can prevent excessive muscles from being pinched by the main air chamber. can do. In addition, pressurization to unnecessary parts is suppressed, and it is possible to effectively apply pressing force only to parts necessary for massage without waste, so even when pressurized air is supplied with a small battery, the battery Consumption can be suppressed, and the pressurization time can be shortened.

  In addition, the width of the left and right main air chambers for clamping is orthogonal to the left and right direction by forming a partition wall that forms a boundary between the pair of left and right main air chambers for holding and the auxiliary air chamber for relaxation. For example, by placing the wider side on the ankle side and the narrower side on the knee side, fit the air bag properly on the foot according to the change in thickness. can do. Moreover, since the ankle side has a wide width, the ankle side can be intensively pressed over the entire circumference with a large area, and a comfortable massage effect can be brought about.

As shown in FIG. 3, the air massage apparatus main body 50 includes a battery (not shown), a pressure pump 51 that supplies pressurized air to the air bag 40, an electric exhaust valve 52 that exhausts air from the air bag 40, air The pressure sensor 53 that detects the air pressure in the bag 40, a controller 55 that creates a massage operation by controlling the pressurization pump 51 and the electromagnetic exhaust valve 52 mainly according to the measurement value of the pressure sensor 53, and the controller 55 are connected. It has a switch and a display (not shown). The air bag 40 is provided with two connection ports 41, 42. One connection port 41 is connected to the discharge port of the pressurizing pump 51 and the connection port of the electromagnetic exhaust valve 52, and the other connection port 42 is connected to the other connection port 42. A pressure sensor 53 is connected.

Next, the air bag 40 of the embodiment will be described in detail with reference to FIGS.
The air bag 40 is formed as a rectangular flat bag body by superposing a pair of flexible resin sheets (for example, made of EVA) and joining the entire peripheral edge portions by heat welding or adhesion. Further, by providing a plurality of linear partition walls 40b, 40c, and 40c at the same time inside the peripheral joint portion 40a by means such as heat welding, the internal space becomes a plurality of air chambers A1, A2, A3, and A4. It is divided into. Further, the non-partition portions (portions indicated by dimensions T21, T22, T23) are left between the partition walls 40b, 40c, 40c and the peripheral joint portion 40a, so that the air chambers A1-A4 communicate with each other. Part B is secured.

  The partition walls 40b, 40c, 40c are provided symmetrically, and the central partition wall 40b is located on the center line L in the left-right direction of the air bag 40. The remaining two partition walls 40c, 40c are provided symmetrically with the central partition wall 40b interposed therebetween, and are formed obliquely with respect to the center line L in the left-right direction of the air bag.

  In FIG. 4, the central partition wall 40b is joined to the upper side of the four sides of the peripheral joint 40a and extends to a position where the dimension T23 is left with respect to the lower side, and is interrupted there. The left and right partition walls 40c, 40c are joined to the upper side of the four sides of the peripheral joint portion 40a, extend linearly by inclining in the direction approaching the center line L, and leave the dimensions T21, T22 with respect to the lower side. Is interrupted. However, there is a relationship of T21 = T22 <T23. Thereby, the communication part B is ensured.

  The dimensions T1 and T2 from the left and right sides of the peripheral joint 40a to the upper ends of the partition walls 40c and 40c and the dimensions T11 and T12 from the left and right sides to the lower ends of the partition walls 40c and 40c are T1 = T2. <T11 = T12. The dimensions T3, T4 from the center line L to the upper ends of the inclined partition walls 40c, 40c and the dimensions T13, T14 from the center line L to the lower ends of the inclined partition walls 40c, 40c are T3 = T4> T13. = T14 relationship. In particular, here, T3 = T4 <T1 = T2.

  By forming the partition walls 40b, 40c, 40c while satisfying such a dimensional relationship, four trapezoidal air chambers A1, A2, A3, A4 are formed. The air chambers A1 and A2 at both the left and right ends are, for example, main air chambers for holding a large area that sandwich the calf muscle portion from the left and right. In addition, the air chambers A3 and A4 arranged between the pair of left and right main air chambers A1 and A2 for relaxing the local compression by the pair of left and right main air chambers A1 and A2 for the muscle portion. It is a secondary air chamber for relaxation that is smaller than the main air chamber.

  Then, due to the above dimensional relationship, the main air chambers A1 and A2 for the left and right clamping pressures are chambers that gradually increase in width from the upper side toward the lower side, and the auxiliary air chambers A3 and A4, on the contrary, from the upper side The room gradually narrows toward the bottom. Therefore, when pressurized air is introduced into the air bag 40, the main air chambers A1 and A2 swell larger than the sub air chambers A3 and A4, and the lower side of the main air chambers A1 and A2 is larger than the upper side. It will swell. The connection ports 41 and 42 are provided on one side of one main air chamber A2.

Next, the operation will be described.
For example, when massaging the user's lower limb Ma with the air massage device 10 using the air bag 40, the band 11 is wound from the back side of the calf as shown in FIGS. That is, the band 11 is placed on the calf with the side with the air bag 40 inward, and the band 11 is wrapped around the resin cover 20 on the base end side of the band 11, and in this state, the fastener 30. The hooks 31 and 32 are fitted into the slits 21 at appropriate positions on the resin cover 21.

  At this time, the band 11 is attached while paying attention to the vertical relationship. That is, the air bag 40 is mounted with the upper side facing upward and the lower side facing downward. By introducing the pressurized air into the air bag 40 after mounting in this manner, the main air chambers A1, A2 and the sub air chambers A3, A4 are inflated as shown in FIG.

  That is, the introduction of the pressurized air causes the main air chambers A1 and A2 having large areas to swell greatly, so that pressing force can be applied to the calf muscle from the left and right sides. Further, when the auxiliary air chambers A3 and A4 press the back side of the calf, excessive muscle pinching by the main air chambers A1 and A2 can be prevented. Thereby, pain and discomfort can be alleviated and reduced when the calf is massaged as if sandwiched from the side. In addition, since it is possible to effectively apply pressing force only to the part necessary for massage, even when pressurized air is supplied with a small battery, it is possible to suppress battery consumption and pressurization time. Can be shortened.

  Further, by forming the partition walls 40c and 40c forming the boundary between the pair of left and right main air chambers A1 and A2 for relaxation and the auxiliary air chambers A3 and A4 for relaxation, the right and left main pressure chambers are formed. Since the widths of the air chambers A1 and A2 are changed so that the lower side becomes wider, the air bag 40 can be worn while appropriately fitting the air bag 40 to the foot in accordance with the change in the thickness of the foot. Moreover, since the wide width part hits the ankle side, the ankle side can be intensively pressed over the entire circumference with a large area, and a comfortable massage effect can be brought about.

  In addition, as shown in FIG. 6, even if the air massage apparatus 10 is mounted on the upper limb Mb of the user, almost the same massage effect can be obtained.

Second Embodiment
Next, an air bag according to a second embodiment will be described.
FIG. 8 is a plan view of the air bag of the second embodiment, and FIG. 9 is a plan view of the air bag and a side view when inflated as seen from each direction. FIG. 10 is a view showing an example of mounting an air massage device using the air bag on a foot tip, and FIG. 11 is a cross-sectional view when the air massage device is mounted on the foot tip.

  As shown in FIG. 10, the air bag 140 is arranged on a wrapping band of an air massage device 10C for a foot tip Mc, and applies pressure and release to the foot tip Mc by introduction and discharge of pressurized air. Is.

  As shown in the plan view of FIG. 8, the air bag 140 is formed in a rectangular shape by superposing a pair of flexible resin sheets (for example, made of EVA) and joining the entire periphery by heat welding or adhesion. It is formed as a flat bag. In addition, by providing a plurality of linear or bent partition walls 140b and 140c at the same time inside the peripheral joint 140a by means of heat welding or the like, the internal space becomes a plurality of air chambers A10 (A11, A12). , A13) and A21. Further, the air chambers A10 (A11 to A13) and A21 communicate with each other by leaving a non-partition portion between the partition walls 140b and 140c and the peripheral joint portion 140a or between the partition wall 140b and the partition wall 140c. A communicating part B is secured.

  In this case, as a plurality of air chambers, two air chambers A10 and A21 spaced apart from each other are formed on both sides in the left-right direction with a non-bulged portion C into which no pressurized air is introduced therebetween. Among these, one air chamber A10 is formed in a large area as an air chamber that hits the sole of the foot, and the other air chamber A21 is formed in a small area as an air chamber that hits only the front side of the instep. These one and other air chambers A10 and A21 are communicated with each other by a communication part B disposed on the front side of the non-bulging part C.

  One large-area air chamber A10 is arranged on both sides in the front-rear direction by a large-area atmospheric arch A12 for a large arch located in the center in the front-rear direction by a short partition wall 140b extending in the left-right direction. It is divided into a plurality of small air chambers A11 and A13 having a small area.

  When a band including the air bag 140 having such a structure is wound around the foot tip Mc, the front portion of the air bag 140 is wound around the fingertip and the rear portion is wound around the heel side.

  When pressurized air is introduced into the air bladder 140 in this way, as shown in FIGS. 9 to 11, the air chambers A <b> 10 (A <b> 11 to A <b> 13) and A <b> 21 are inflated so Is reported.

  That is, since the air chamber A12 which swells greatly hits the central part of the earth arch by introducing the pressurized air, the sole can be comfortably squeezed about the area of the earth arch. At that time, the front side of the back of the foot is backed up by the air chamber A21 on the opposite side, so that the cushioning action can assist in pressing the back side of the foot without causing unnecessary pain.

  Further, since the small air chambers A13 and A11 in which the bulge is suppressed to a minimum hit the heel side portion and the position close to the fingertip, the bulge of the air chamber A12 can be supported. Moreover, since the air chamber 21 on the back side opposite to the small air chamber A11 on the fingertip side swells, the fingertip side portion is evenly sandwiched from above and below, so that a finger pressure effect can be brought about at the finger base portion. Further, since the non-bulged portion C hits the instep side and the side surface of the foot near the ankle, the burden on the ankle can be reduced, and the pressurized air can be turned to another air chamber.

  In short, it is possible to effectively apply pressing force only to the parts necessary for massage, so even when pressurized air is supplied with a small battery, battery consumption can be suppressed, and pressurization time Can be shortened.

<Third Embodiment>
Next, an air bag according to a third embodiment will be described.
FIG. 12 is a plan view of the air bag of the third embodiment, and FIG. 13 is a plan view of the air bag and a side view when inflated as seen from each direction. FIG. 14 is a view showing an example of attachment of the air massage device using the air bag to the arm (between wrist and elbow), and FIG. 15 is a cross-sectional view of the air massage device attached to the arm.

  As shown in FIG. 14, the air bag 240 is arranged on a wrapping band of the air massage device 10D for the arm Md, and applies pressure and release to the arm Md by introducing and discharging pressurized air. is there.

  As shown in the plan view of FIG. 12, the air bag 240 is formed in a rectangular shape by superposing a pair of flexible resin sheets (for example, made of EVA) and joining the entire peripheral edges by heat welding or adhesion. It is formed as a flat bag. In addition, by providing a plurality of linear or bent partition walls 240b and 240c at the same time inside the peripheral joint 240a by means such as thermal welding, the internal space becomes a plurality of air chambers A41 and A40 (A42). It is divided into. Further, the non-partition portion is left between the partition walls 240b and 240c and the peripheral joint portion 240a, so that the communication portion B that communicates between the air chambers A41 and A40 is secured.

  In this case, as a plurality of air chambers, two air chambers A41 and A40 spaced apart from each other with a non-bulged portion C into which pressurized air is not introduced are formed on both sides in the left-right direction. An air chamber that hits the belly of the arm is formed in a large area, and the other air chamber A40 is divided into a plurality of small air chambers A42 that have a small area as an air chamber that hits the back of the arm. The one and the other air chambers A41 and A40 are communicated with each other by a communication portion B disposed on the front side of the non-bulging portion C.

  When the band including the air bag 240 having such a configuration is wound around the arm Md, the front portion of the air bag 240 is wound toward the wrist and the rear portion is wound around the arm Md.

  When the compressed air is introduced into the air bag 240 in this way, as shown in FIGS. 13 to 15, the air chambers A41 and A42 are inflated so that the pressing force is transmitted to the abdomen of the arm without waste. .

  That is, since the large-sized air chamber A41 that swells greatly hits the position of the belly of the arm by the introduction of the pressurized air, the abdomen can be comfortably massaged. At this time, since the back side of the arm is backed up by a plurality of air chambers A42 having a different small area, the cushion action can assist in pressing the abdomen of the arm without causing unnecessary pain.

  Moreover, since the non-bulging part C hits the side part of an arm, pressurized air can be turned to another air chamber. In short, it is possible to effectively apply pressing force only to the parts necessary for massage, so even when pressurized air is supplied with a small battery, battery consumption can be suppressed, and pressurization time Can be shortened.

  In addition, the band which each has the air bags 40, 140, and 240 of each said embodiment is prepared, and it wears while exchanging the air massage apparatus main body 50, By one air massage apparatus main body 50, body You can massage everywhere.
