(First embodiment)
A first embodiment of a massage device according to the present invention will be described below with reference to the drawings. FIG. 1 shows the appearance of a seat 2 provided with a massage device 1 according to the present invention. The seat 2 includes a seat bottom 2 a (sitting portion), a seat back 2 b (backrest portion), and a seat frame 2 c that constitutes a framework of the seat 2. The seat bottom 2a (sitting part) and the seat back 2b (backrest part) have a base part 21 made of a pad member or the like and a substantially flat base surface 21a (see FIG. 2), and a seating side surface of the base part 21 And a skin member 22 made of cloth (or leather, etc.) so as to cover the cover. Further, in the seat back 2b (backrest portion), a pair of left and right massage devices 1 are arranged in the vertical direction between the base portion 21 and the skin member 22, and are arranged in a total of eight locations.
As shown in FIGS. 2 and 3, the massage device 1 includes a pressing airbag 4, a compressed air supply / discharge device 7, a control device 8, and an input device 9.

  The pressing airbag 4 is a cloth-like resin fiber member having non-stretchability, flexibility, and low air permeability, and is formed in a hollow ring shape as a whole. The pressing airbag 4 is divided into a plurality of (four in this embodiment) pressing airbags 4a, 4b, 4c, 4d by four partition walls 41a, 41b, 41c, 41d. These partition walls 41a, 41b, 41c, and 41d are formed on the inner peripheral surface of one hollow ring-shaped airbag, for example, by welding. The pressing airbags 4a, 4b, 4c, and 4d are arranged on the base portion 21 as the first pressing airbag 4a, the second pressing airbag 4b, the third pressing airbag 4c, and the fourth pressing airbag 4d in this order. It is arranged in a ring shape. Further, in the partition wall 41, between the first pressing airbag 4a and the second pressing airbag 4b, between the second pressing airbag 4b and the third pressing airbag 4c. The three partition walls 41b of the third partition wall 41c between the second partition wall 41b, the third pressing airbag 4c and the fourth pressing airbag 4d are formed with throttle openings and are like orifice plates. The second to fourth throttle passages 44b, 44c and 44d are formed. The fourth pressing airbag 4d disposed at the rear end is connected to the third pressing airbag 4c at the front stage only via a fourth throttle passage 44d provided in the third partition wall 41c. The first pressing airbag 4a is blocked by the fourth partition wall 41d.

  The first pressing airbag 4 a disposed at the tip on the base portion 21 is connected to the air pump 17 via the first air supply / exhaust pipe 11. The first air supply / exhaust pipe 11 branches to a first exhaust pipe 11a communicating with the outside air in the middle of the first pressing airbag 4a side. The first air supply / exhaust pipe 11 is provided with a first ventilation shut-off valve 11 b that shuts off air flow between the first pressing airbag 4 a and the air pump 17. The inner diameter of the first air supply / exhaust pipe 11 is smaller than the inner diameter of the flow passage of the first pressing airbag 4a and functions as the first throttle passage 44a.

  The first exhaust pipe 11a is provided with a first exhaust cutoff valve 11c that shuts off air flow. The first ventilation cutoff valve 11b and the first exhaust cutoff valve 11c are configured by, for example, an electromagnetic switching valve that is switched by an electromagnetic solenoid. The air pump 17 is an electric motor type pump that is operated by an electric motor, for example. The compressed air supply / discharge device 7 is constituted by the air pump 17, the first ventilation cutoff valve 11b, the first exhaust cutoff valve 11c, and the like.

  The control device 8 controls the operation of the compressed air supply / discharge device 7 including the first ventilation cutoff valve 11b, the first exhaust cutoff valve 11c, the air pump 17, and the like. Connected to the control device 8 is an input device 9 (controller) for turning on / off the power source and allowing the user to input the operation duration time of the massage device 1.

Next, the operation of the massage device 1 will be described below.
The pressure of the compressed air supplied by the compressed air supply / discharge device 7 is P0, the air pressure inside the first pressing airbag 4a is P1, the air pressure inside the second pressing airbag 4b is P2, and the third pressing pressure is used. The air pressure inside the airbag 4c is P3, and the air pressure inside the fourth pressing airbag 4d is P4.
Moreover, in the massage apparatus 1 before the operation, the first exhaust cutoff valve 11c is opened and the first ventilation cutoff valve 11b is closed.

The user operates the input device 9 to turn on the power source, and selects, for example, the shoulder part (the left and right massage device 1 at the top) of the upper back as the treatment part, and the massage apparatus. 1 is activated.
The control device 8 operates the air pump 17 to close the first exhaust cutoff valve 11c and open the first ventilation cutoff valve 11b.

  The air pump 17 starts supplying compressed air into the first pressing airbag 4a. Since the first pressing airbag 4a is not formed of an elastic material, the inflation of the first pressing airbag 4a is completed. The case where the inflation is actually completed and the case where the inflation of the first pressing airbag 4a is restricted by the reaction force from the user's treatment site with which the first pressing airbag 4a comes into contact are considered. ) Until a reaction force (tension) is generated from the first airbag 4a, P1 is substantially the same as the atmospheric pressure. The air pressure P2 in the second pressing airbag 4b adjacent to the first pressing airbag 4a is also the same as the atmospheric pressure. Therefore, the compressed air of the compressed air supply / discharge device 7 hardly flows out from the first pressing airbag 4a and flows into the second pressing airbag 4b.

  Therefore, the compressed air supplied from the compressed air supply / exhaust device 7 is first higher than the atmospheric pressure in the first pressing airbag 4a by inflating the first pressing airbag 4a and completing the expansion. Pressure P1 is generated.

  The compressed air flows from the first pressing airbag 4a into the second pressing airbag 4b by the air pressure P1 higher than the atmospheric pressure, and the second pressing airbag 4b is inflated. Thereafter, in the same manner, the third pressing airbag 4c and the fourth pressing airbag 4d are inflated in order to complete the inflation.

Next, each pressing air bag 4a, 4b, 4c, 4d is inflated, and a reaction force (tension) is generated from each pressing air bag 4a, 4b, 4c, 4d (inflated state is completed) ) Is considered based on FIG.
The flow resistance of the first throttle passage 44a is R1, the flow resistance of the second throttle passage 44b is R2, the flow resistance of the third throttle passage 44c is R3, and the flow resistance of the fourth throttle passage 44d is R4. To do. The flow velocity of air passing through the first throttle passage 44a is Q1, the flow velocity of air passing through the second throttle passage 44b is Q2, the flow velocity of air passing through the third throttle passage 44c is Q3, and passes through the fourth throttle passage 44d. Let the air flow rate be Q4.

ここで、各押圧用エアバッグ４ａ，４ｂ，４ｃ，４ｄの膨張が完了するためには、各押圧用エアバッグにおけるエアの流入量と流出量とが同じであると考えられる。そのため、各絞り通路４４ａ，４４ｂ，４４ｃ，４４ｄを通過するエアの各流速が等しいとすると、Ｑ１＝Ｑ２＝Ｑ３＝Ｑ４が成立する。
このように各流速が等しい場合において、（１）式と（２）式とにより、

The pressure difference is considered to be equal to the product of the flow velocity Q1 and the flow path resistance R1 when passing through the first throttle passage 44a.

Similarly, in the second throttle passage 44b,

Similarly, in the third throttle passage 44c,

Here, in order to complete the expansion of the pressing airbags 4a, 4b, 4c, and 4d, it is considered that the inflow amount and the outflow amount of air in each pressing airbag are the same. Therefore, assuming that the flow velocities of the air passing through the throttle passages 44a, 44b, 44c, and 44d are equal, Q1 = Q2 = Q3 = Q4 is established.
Thus, when each flow velocity is equal, (1) Formula and (2) Formula,

And
And between the first pressing airbag 4a and the second pressing airbag 4b adjacent to the first pressing airbag 4a,

This relationship is established.
Similarly, between the second pressing airbag 4b and the third pressing airbag 4c adjacent to the second pressing airbag 4b,

This relationship is established.
Similarly, between the third pressing airbag 4c and the fourth pressing airbag 4d adjacent to the third pressing airbag 4c,

This relationship is established. Thus, each of the pressing airbags 4a, 4b, 4c, and 4d completes the inflation by the relationship of the pressure difference established by the expressions (6) to (8).

  Thus, the first pressing airbag 4a, the second pressing airbag 4b, the third pressing airbag 4c, and the fourth pressing airbag 4d arranged in a ring shape on the base portion 21 are arranged. By expanding in ordinal order, it is possible to realize a ring-shaped ridge that moves a portion pressurized by the pressing airbag into a ring shape.

When the expansion is completed, the control device 8 closes the first ventilation cutoff valve 11b of the first supply / exhaust pipe 11 and opens the first exhaust cutoff valve 11c of the first exhaust pipe 11a. Thereby, air is exhausted from the pressing airbag 4 to the outside air, and all the pressing airbags 4a, 4b, 4c, and 4d are contracted.
Hereinafter, similarly, compressed air is supplied from the air pump 17 to the first pressing airbag 4a, and the first pressing airbag 4a to the fourth pressing airbag 4d are sequentially inflated.

  As is clear from the above description, in the massage device 1 according to the first embodiment, the base portion 21 including the base surface 21a and the plurality of pressing airbags 4a, 4b, 4c arranged side by side with the base portion 21. , 4d, and a compressed air supply / discharge device 7 for supplying / extracting compressed air to / from the plurality of pressing airbags 4a, 4b, 4c, 4d to inflate and contract each of the pressing airbags 4a, 4b, 4c, 4d, The adjacent pressing airbags 4a, 4b, 4c, and 4d are connected to each other through the throttle passages 44a, 44b, 44c, and 44d, and the pressing airbag 4a disposed at the front end is connected to the second throttle passage 44b. The fourth pressing airbag 4d, which is connected to the compressed air supply / discharge device 7 through the rear end and disposed at the rear end, is connected only to the first third pressing airbag 4c through one fourth throttle passage 44d. It has been.

  According to this, compressed air is first supplied from the compressed air supply / discharge device 7 to the first pressing airbags 4a arranged at the tips. In the first pressing airbag 4a at the tip, the internal pressure is slightly increased by the inflowing compressed air, and the leading pressing airbag 4a is inflated. The air pressure P1 inside the first pressing airbag 4a at the front end is increased by the reaction and the reaction force (tension) from the first pressing airbag 4a is generated. It becomes higher than the air pressure P2 inside the bag 4b. The adjacent second pressing airbag 4b is inflated with a slight increase in the internal air pressure P2 when compressed air flows from the leading first pressing airbag 4a. Thereafter, in the same manner, the airbags are inflated in the order in which they are arranged up to the fourth pressing airbag 4d at the rear end.

  In this way, since the plurality of pressing airbags 4a, 4b, 4c, 4d are inflated in the order in which they are arranged side by side, the same operation as a heel that pressurizes while moving the user's treatment site is performed. Can be realized.

In the massage device 1 according to the first embodiment, the plurality of pressing airbags 4 a, 4 b, 4 c, 4 d are arranged in a ring shape on the base portion 21.
According to this, each of the pressing airbags 4a, 4b, 4c, 4d is arranged in a ring shape on the base portion 21, and a plurality of pressing airbags 4a, 4b, 4c, 4d arranged in a ring shape are arranged. It expands in order. Therefore, the massage device 1 can realize the same operation as a ring-shaped heel that pressurizes while moving a user's treatment site in a ring shape.

(Second embodiment)
A second embodiment in which the massage device according to the present invention is embodied will be described below with reference to FIGS. 5 and 6.
In the massage device 101 according to the second embodiment, a plurality of pressing airbags 104a, 104b, 104c, 104d partition the pressing airbags 104a, 104b, 104c, 104d adjacent to each other, not a partition wall, but a hollow By the 1st connecting pipe 141a, the 2nd connecting pipe 141b, and the 3rd connecting pipe 141c which are formed with a pipe | tube.
In each of the pressing airbags 104a, 104b, 104c, 104d, for example, in the second pressing airbag 104b, the second throttle passage 144b (first connecting pipe 141a) on the side into which the compressed air flows when inflated, and the outflow side The third throttle passage 144c (second connecting pipe 141b) is set with the same flow resistance. These points are different from the first embodiment. Since other configurations are the same, the same reference numerals are given and description thereof is omitted.

The differences will be described in detail below.
These first to third connecting pipes 141a, 141b, 141c are made of the same material as the pressing airbags 104a, 104b, 104c, 104d, for example. The cross-sectional areas of the hollow portions of the first connecting pipe 141a, the second connecting pipe 141b, and the third connecting pipe 141c are perpendicular to the circumferential direction of the pressing airbags 104a, 104b, 104c, and 104d arranged in a ring shape. Are formed smaller than the cross-sectional area of the hollow portion. Therefore, the first connecting pipe 141a functions as the second throttle path 144b, the second connecting pipe 141b functions as the third throttle path 144c, and the third connecting pipe 141c functions as the fourth throttle path 144d. The first air supply / exhaust pipe 11 connected to the first pressing airbag 104a also functions as the first throttle passage 144a.

  In addition, the first throttle passage 144a, the second throttle passage 144b, the third throttle passage 144c, and the fourth throttle passage 144d have the same throttle passage on the side into which compressed air flows during expansion and the throttle passage on the outflow side. It is set by channel resistance. In order to set with equal channel resistance, for example, the inner diameter and length of the first connecting pipe 141a, the second connecting pipe 141b, and the third connecting pipe 141c can be formed to be equal. About the 1st air supply / exhaust pipe 11, the diameter and length are adjusted, and the 1st connection pipe 141a and channel resistance are formed equally.

In this way, each of the throttle passages 144a, 144b, 144c, and 144d is cut smaller than the cross-sectional area of the hollow portion in the direction perpendicular to the circumferential direction of each of the pressing airbags 104a, 104b, 104c, and 104d arranged in a ring shape. By setting the connecting pipes 141a, 141b, and 141c to have the same area, it is possible to make the flow path resistance similar to the restriction resistance by the orifice plate.
Further, by equalizing the flow path resistance of each of the throttle passages 144a, 144b, 144c, and 144d, the flow velocity of the air flowing into each of the pressing airbags 104a, 104b, 104c, and 104d is made uniform, and each pressing air is at the same timing. The bags 104a, 104b, 104c, and 104d can be inflated.

  As is apparent from the above description, the massage device 101 according to the second embodiment has the first throttle passage 144a, the second throttle passage 144b, the third throttle passage 144c, and the fourth throttle passage 144d to which compressed air flows during expansion. For example, the first throttle passage 144a on the side to be discharged and the second throttle passage 144b on the outlet side are set with equal flow resistance.

  According to this, in each pressing airbag 104a, 104b, 104c, and 104d, since the inflow side throttle passage 144a and the outflow side throttle passage 144b have the same flow resistance, The flow path resistances of the throttle passage 144b adjacent to the throttle passage 144a are equal. Therefore, the compressed air supplied to the pressing airbags 104a, 104b, 104c, 104d flows in at the same flow rate, and the pressing airbags 104a, 104b, 104c, 104d are the same in the order in which they are arranged. It expands at the timing. Accordingly, the plurality of pressing airbags 104a, 104b, 104c, and 104d can be inflated in order with a smooth movement to realize the same operation as a bag.

  The “throttle passage” in the present application is not limited to a resistance like an orifice plate in which an opening having a diameter smaller than that of the air flow passage is provided in the middle of the air flow passage, as in the second embodiment. The throttle tube is throttled by a connecting pipe having an inner diameter (cross-sectional area) smaller than the inner diameter (cross-sectional area of the hollow portion in a direction perpendicular to the circumferential direction arranged in a ring shape) of the flow passage of the pressing airbags 104a, 104b, 104c, 104d. A passage may be formed.

(Third embodiment)
A third embodiment of the massage device according to the present invention will be described below with reference to FIGS. 7 and 8.

Further, the air volume of the airbag is gradually increased toward the fourth pressing airbag 204d. And it inflates in order from the 1st pressurization airbag 204a, and complete | finishes inflation quickly. Further, as shown in FIG. 8, the amount of protrusion B1, B2, B3, B4 from the base surface 21a when the inflation is completed is also the smallest in the first pressing airbag 204a, and the fourth pressing It is set so as to gradually increase toward the airbag 204d (in order from the first pressing airbag 204a). The first throttle passage 244a, the second throttle passage 244b, the third throttle passage 244c, and the fourth throttle passage 244d are provided on the outer peripheral side of the pressing airbags 204a, 204b, 204c, and 204d arranged in a ring shape. ing. Further, the channel resistances of the first throttle passage 244a, the second throttle passage 244b, the third throttle passage 244c, and the fourth throttle passage 244d are set equal. The massage apparatus 201 of the third embodiment is different from the first embodiment in these points, and the other configurations are the same as those of the first embodiment, and thus the same reference numerals are given and description thereof is omitted.

The protruding amounts B1, B2, B3, and B4 from the base surface 21a are set to be sequentially smaller in order from the earliest time when the pressing airbags 204a, 204b, 204c, and 204d complete inflation.

  According to this, when compressed air is supplied to the plurality of pressing airbags 204a, 204b, 204c, and 204d, the expanding airbags 204a, 204b, 204c, and 204d have a base surface that is delayed as the timing of completing the inflation is delayed. The amount of protrusion B1, B2, B3, B4 from 21a increases. Therefore, the plurality of pressing airbags 204a, 204b, 204c, and 204d can gradually and strongly press the user's treatment site along the arrangement. And the user becomes strongly clear in the pressing feeling of the treatment site by the difference in the pressing amount (protruding amount) between the adjacent first pressing airbag 204a and the second pressing airbag 204b, for example. In this way, by gradually and strongly pressing the treatment site of the user, it is possible to realize a wrinkle that makes the user feel a pressing feeling clearly.

Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.
In the massage device 301 according to the fourth embodiment, even when a plurality of pressing airbags 304a, 304b, 304c, and 304d are connected in parallel to the air pump 17, the pressing airbags 304a, 304b, and 304c arranged in a ring shape. , 304d are inflated in order, and a ring-shaped ridge can be realized.
In this embodiment, the pressing airbags 304a, 304b, 304c, and 304d have the same volume. However, the present invention is not limited to this. For example, the pressing airbag having a slower inflation order is set to have a larger volume. Also good.

In the passage 344, the flow passage resistance is set to be smaller in the throttle passage 344a in the earlier expansion order than in the slow passage 344b.

  According to this, each throttle passage 344 is formed with the same volume as the throttle passage 344a of the pressing airbag 304 in the early inflation order is set to have a smaller flow resistance than the throttle passage 344b in the later inflation order. The first to fourth pressing airbags 304a, 304b, 304c, 304d are connected to the compressed air supply / discharge device 7 in parallel via the first to fourth throttle passages 344a, 344b, 344c, 344d. Therefore, when compressed air is supplied from the compressed air supply / discharge device 7, each of the pressing airbags 304a, 304b, 304c, 304d is connected to the compressed air supply / discharge device 7 via the throttle passage 344 having a small flow resistance. The pressed airbags 304a, 304b, 304c, 304d are inflated in order. For this reason, the plurality of pressing airbags 304a, 304b, 304c, and 304d that are arranged side by side inflate quickly in the order in which they are arranged side by side. A similar operation can be realized.

  In addition, in the said embodiment, although the several airbag 4 for a press was made into four, it is not limited to this, For example, six or eight may be sufficient. By increasing the number, the movement of the bulge of the pressing airbag can be made smooth to the user.

  Further, the throttle diameter of the throttle flow passage may be gradually reduced from the first pressing airbag toward the fourth pressing airbag. Thereby, it is possible to change the timing at which each pressing airbag is inflated.

  The present invention is not limited to the embodiment described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
