  The control unit 13 switches the circuit in the control valve 12 so that the first leg airbag 111, the second leg airbag 112, the foot side airbag 120, and the second composite airbag 200 are switched. Change the air supply and discharge status for each.

  When the first leg airbag 111 is inflated, the control unit 13 sets a circuit in the control valve 12 so that the air pump 11 and the first air tube 71 are connected to each other. For this reason, the air discharged from the air pump 11 flows into the first leg airbag 111 via the first air tube 71 and the first supply port 101. For this reason, the first leg airbag 111 is inflated. When the first leg air bag 111 is deflated, the control unit 13 sets a circuit in the control valve 12 so that a passage connected to the first air tube 71 is opened to the atmosphere. For this reason, the air in the first leg airbag 111 is discharged to the atmosphere via the first supply port 101 and the first air tube 71. For this reason, the first leg airbag 111 contracts.

  The control unit 13 sets a circuit in the control valve 12 so that the air pump 11 and the second air tube 72 are connected to each other when the second leg airbag 112 and the foot side airbag 120 are inflated. To do. For this reason, the air discharged from the air pump 11 flows into the second leg air bag 112 through the second air tube 72 and the second supply port 102, and further from the second leg air bag 112. It flows into the side airbag 120. For this reason, the 2nd leg airbag 112 and the leg side airbag 120 expand | swell. When the second leg air bag 112 and the leg side air bag 120 are contracted, the control unit 13 sets a circuit in the control valve 12 so that the passage connected to the second air tube 72 is opened to the atmosphere. . For this reason, the air in the second leg airbag 112 and the foot side airbag 120 is discharged to the atmosphere via the second supply port 102 and the second air tube 72. For this reason, the second leg airbag 112 and the leg side airbag 120 contract.

  The control unit 13 sets a circuit in the control valve 12 so that the air pump 11 and the third air tube 73 are connected to each other when the sole air bag 210 and the instep air bag 230 are inflated. For this reason, the air discharged from the air pump 11 flows into the second sole air bag 212 via the third air tube 73 and the supply port 201. Further, the air in the second sole airbag 212 flows into the first sole airbag 211 via the sole communication portion 240. Further, the air in the first sole airbag 211 flows into the upper airbag 230 via the side communication portion 250. For this reason. The sole airbag 210 and the upper airbag 230 are inflated. When the sole air bag 210 and the instep air bag 230 are contracted, the control unit 13 sets a circuit in the control valve 12 so that a passage connected to the third air tube 73 is opened to the atmosphere. For this reason, the air in the sole air bag 210 and the instep air bag 230 is discharged to the atmosphere through the supply port 201 and the third air tube 73. For this reason, the sole airbag 210 and the instep airbag 230 contract.

With reference to FIG. 8, the structure of the auxiliary tool 90 is demonstrated.
The assisting device 90 is used for locally giving a massage feeling stronger than the massage feeling given to the lower limbs by the first leg airbag 111 (see FIG. 6) and the second leg airbag 112 (see FIG. 6). It is done. The auxiliary tool 90 includes a protrusion 91 that is used for the lower limb, a base 92 to which the protrusion 91 is attached, and a handle 93 that is formed on the base 92. The protrusion 91 is formed at the center portion of the base 92.

With reference to FIG. 9, the use state of the auxiliary tool 90 is demonstrated. The hatching shown in FIG. 9 indicates the user's lower limb.
The auxiliary tool 90 is inserted between the boot 20 and the lower limb. The width of the handle 93 is narrower than the width of the base 92. Further, the height from the top surface of the base 92 to the top surface of the handle 93 is lower than the height from the top surface of the base 92 to the top surface of the protrusion 91. For this reason, when the auxiliary tool 90 is inserted between the boot 20 and the lower limb, a space is formed between the top surface of the base 92 and the top surface of the protrusion 91.

A first usage pattern will be described with reference to FIGS. 6, 7 </ b> B, and 10.
The user operates the operation unit 17 to select one of the pre-programmed massage modes. Here, as an example, a squeezed massage pattern, which is one of pre-programmed massage modes, will be described.

  First, supply of air to the sole airbag 210, the inner airbag 220, and the upper airbag 230 is started, and the heater unit 50 outputs heat. For this reason, when the first sole airbag 211 and the second sole airbag 212 of the sole airbag 210 are inflated, the base of the toes and the arch of the foot are massaged.

  The first sole airbag 211 has a portion that is in contact with the support base 53 configured integrally with the heater unit 50 and a portion that is not in contact with the support base 53. The portion in contact with the support base 53 tilts the support base 53 as the first sole air bag 211 is inflated. For this reason, the part between the base of the toe and the foot arch, which is the part of the foot that is in contact with the support base 53, is massaged by the support base 53. Further, the portion that is not in contact with the support base 53 expands more than the portion that is in contact with the support base 53 as the first sole airbag 211 expands. At this time, a portion of the first sole airbag 211 that is not in contact with the support base 53 is expanded to a position higher than the top surface of the support base 53. For this reason, due to the expansion of the sole air bag 210, the base of the toe and the arch of the foot are massaged more strongly than the portion between the base of the toe and the arch of the foot.

  In addition, the arch of the foot is massaged from the inside by inflating the inner airbag 220. Further, the instep air bag 230 is inflated to massage the instep. At this time, the instep airbag 230 presses the sole against the first sole airbag 211 and the second sole airbag 212, so that the first sole airbag 211 and the second sole airbag 212 are pressed. The massage feeling given by improves.

  Then, after a predetermined time has elapsed since the supply of air to the sole airbag 210, the inner airbag 220, and the upper airbag 230 is started, the second leg airbag 112, and the foot side portion Supply of air to the airbag 120 is started. Therefore, the outer leg airbag 121 and the inner leg airbag 122 of the leg side airbag 120 are inflated, so that the lower part of the ankle of the foot is massaged so as to be sandwiched from the outer side and the inner side of the foot. The The outer leg airbag 121 and the inner leg airbag 122 are branched from the second leg airbag 112 so as to avoid the portion of the leg covering portion 30 that faces the back of the heel. For this reason, the back of the heel is not substantially massaged. Moreover, since the heel support component 60 is disposed on the back side of the heel, it is not substantially massaged. For this reason, the lower part of the ankle of the foot is massaged more strongly than the back of the heel and the back of the heel. In addition, when the second leg airbag 112 is inflated, the soleus of the lower leg is massaged.

  Then, after a predetermined time has elapsed since the supply of air to the second leg airbag 112 and the foot side airbag 120 is started, the supply of air to the first leg airbag 111 is started. Is done. For this reason, when the first leg airbag 111 is inflated, the gastrocnemius of the lower leg is massaged.

  In this way, massage is performed so as to squeeze from the user's foot to the gastrocnemius. According to this squeezed-up massage pattern, it contributes to effectively eliminating swelling of the legs by pushing up blood and waste products in the blood to the heart side.

The second usage pattern will be described with reference to FIGS. 6, 7 </ b> B, and 11.
The user inserts the auxiliary tool 90 between the boot 20 and the lower limb before operating the operation unit 17. The position where the auxiliary tool 90 is inserted is arbitrarily set by the user. An example of the position where the auxiliary tool 90 is inserted is a shin recess. The user selects one of the pre-programmed massage modes by operating the operation unit 17 after inserting the auxiliary tool 90.

  When the massage is started, at least one of the leg airbag 110, the foot side airbag 120, the sole airbag 210, the inner airbag 220, and the upper airbag 230 is inflated. Along with this, a pulling force is applied to the boot 20. For this reason, in a state where the auxiliary tool 90 is inserted between the boot 20 and the lower leg, when such force acts on the boot 20, the auxiliary tool 90 is strongly pressed against the lower limb. For this reason, the pressed part is massaged by the auxiliary tool 90.

According to the air massage device 1, the following actions and effects can be obtained.
(1) By emphasizing the base of the toes and the arch of the foot, it is possible to give a favorable massage feeling to the sole as compared to the case of emphasizing only the arch of the foot. It is preferable to further consider the following points. That is, even if the part including the base of the toe, the arch of the foot, and the part between the base of the toe and the arch of the foot is emphasized and massaged more than the other part of the sole, Is strongly massaged, it becomes relatively difficult to emphasize the massage feeling of the base of the toes and the arch of the foot.

  According to the air massage device 1, in consideration of such matters, the sole air bag 210 that massages the base of the toe and the arch of the foot more strongly than the portion between the base of the toe and the arch of the foot is configured. Has been. For this reason, it becomes easy to emphasize the massage feeling of the base of the toe and the arch of the foot. For this reason, a preferable massage feeling can be given to the soles.

  (2) According to the air massage device 1, the sole communication portion 240 connects the space inside the first sole airbag 211 and the space inside the second sole airbag 212 to each other. For this reason, compared with the case where the 1st sole air bag 211 and the 2nd sole airbag 212 are formed separately, the structure of the sole airbag 210 is simplified. For this reason, the productivity regarding the sole air bag 210 is improved.

  (3) According to the air massage device 1, the non-inflatable portion 260 is disposed in a portion of the foot covering portion 40 that faces the base of the toe and the foot arch. For this reason, compared with the case where it is assumed that the part corresponding to the non-inflatable part 260 is formed as an inflatable part, the feeling of massage at the base of the toes and the arch of the foot is more emphasized.

  (4) According to the air massage device 1, the heater element 51 is installed on the non-expanded portion 260. For this reason, the sole can be massaged by the sole airbag 210 while the sole is warmed by the heater element 51. For this reason, a feeling of massage similar to a feeling of massage by a human hand can be given to the soles. In addition, since it is not necessary to substantially consider the influence on the heater element 51 due to the inflating of the sole air bag 210, the configuration of the heater element 51 can be selected from various options.

  (5) According to the air massage device 1, the upper airbag 230 presses the sole against the first sole airbag 211 and the second sole airbag 212. For this reason, since the force with which the sole airbag 210 pushes the sole is supported by the instep airbag 230, the sole is massaged more strongly. For this reason, a preferable massage feeling can be given to the soles.

  (6) According to the air massage device 1, the sole communication portion 240 connects the space inside the first sole airbag 211 and the space inside the second sole airbag 212 to each other. Further, the side communication portion 250 connects the space inside the first sole airbag 211 and the space inside the upper airbag 230 to each other. For this reason, the structure of an airbag is simplified compared with the case where the sole air bag 210 and the back airbag 230 are formed separately. For this reason, the productivity regarding an airbag improves.

  (7) When the toes of the toes are pushed by the air bag, the feeling of pressure on the toes that the user remembers becomes strong, and the user may feel uncomfortable. According to the air massage device 1, the side communication portion 250 is formed on the outer side of the foot so as not to come into contact with the little toe in consideration of such matters. For this reason, it is avoided that the toe of a toe is pressed by the side part communication part 250, and it becomes difficult for a user to feel discomfort.

  (8) According to the air massage device 1, the electric wire 74 is routed so as to pass between the second sole airbag 212 and the side communication portion 250. For this reason, a boundary between the second sole air bag 212 and the side communication portion 250 is formed. For this reason, compared with the case where the 2nd sole airbag 212 and the side part communication part 250 are connected directly, the massage of the sole by the 2nd sole airbag 212 becomes easy to be emphasized. Further, since the electric wire 74 can be routed to the rear side of the second sole air bag 212, the electric wire 74 can be routed on the rear side of the boot 20 in order to connect the electric wire 74 to the power supply circuit 14. For this reason, when a user uses the air massage apparatus 1, the electric wire 74 connected with the power supply circuit 14 is hard to obstruct a user's operation | movement.

  (9) According to the test conducted by the present inventor, in addition to massaging the arch from the sole side, it is confirmed that the user feels a more comfortable massage feeling by further massaging the arch from the inside of the foot. Yes. The air massage device 1 further includes an inner air bag 220 that massages the arch of the foot from the inside of the foot in consideration of such matters. For this reason, a comfortable massage feeling can be given to the user.

  (10) When a toe is pushed from the inside by an air bag, the toe of the toe may be strongly pressed against the forefinger of the foot. Furthermore, the forefinger, the middle finger, and the ring finger of the foot may be strongly pressed against the toes that exist outside the toes. Further, when the toes are pushed from the outside by the air bag, the little toes of the toes may be strongly pressed against the ring fingers of the toes. Furthermore, the ring finger of the foot, the middle finger of the foot, and the index finger of the foot may be strongly pressed against the toes inside each toe. In this way, when the toes are strongly pressed against adjacent toes, the feeling of pressure on the toes that the user learns becomes strong, and the user may feel uncomfortable.

  According to the air massage device 1, in consideration of such matters, there is no air bag in the portion of the boot 20 that faces the inside of the thumb of the toe and the portion that faces the outside of the little toe of the foot. For this reason, the inner side of a toe, the outer side of a toe, or both are not compressed by an air bag. This makes it difficult for the user to feel discomfort.

  (11) The user who uses the air massage device 1 has the strength to fasten the leg covering portion 30 with the leg tightening portion while confirming the fit between his / her lower leg and the boot 20 and the foot covering portion 41 The strength of tightening 40 can be individually adjusted. For this reason, when a plurality of users use the air massage device 1, each user can fit the entire boot 20 to his or her lower limbs and receive a massage with an air bag depending on the state. For this reason, the possibility that the effect of massage is reduced due to the difference in the shape of the lower limb for each user is reduced.

  (12) According to the air massage device 1, the first leg fastening part 31, the second leg fastening part 32, and the foot fastening part 41 are hook-and-loop fasteners. For this reason, for example, compared with the case where each leg fastening part 31 and 32 and the foot fastening part 41 are formed with a string, a user can adjust the strength which fastens the leg covering part 30 and the foot covering part 40 easily. Can do.

  (13) As an example of the configuration of the leg tightening portion, a portion corresponding to a portion around the lower gastrocnemius muscle in the leg covering portion 30 and a portion corresponding to the portion around the soleus muscle of the lower leg in the leg covering portion 30 are used as one leg. The structure tightened by a fastening part is mentioned. On the other hand, the difference in thickness appears remarkably in the part around the gastrocnemius of the lower leg and the part around the soleus of the lower leg. In addition, according to a user whose thickness around the gastrocnemius is thicker than a standard thickness, the difference in the thickness of each of the above portions appears more prominently. For this reason, when the user wears the boot having the leg tightening portion in the above example, the leg covering portion and the portion around the soleus of the lower leg do not fit properly even if the leg tightening portion is sufficiently tightened. There is a fear. In addition, according to a user having a particularly large difference in thickness between the above portions, the fit between the leg covering portion and the portion around the soleus of the lower leg may be further reduced.

  According to the air massage apparatus 1, the first leg fastening part 31 and the second leg fastening part 32 are configured in consideration of such matters. For this reason, the user who uses the air massage device 1 confirms the fit between the lower leg gastrocnemius muscle and the leg covering part 30, and the lower leg sole muscle and the leg covering part 30. However, the strength with which the leg covering portion 30 is tightened by the leg tightening portions 31 and 32 can be individually adjusted. For this reason, when a plurality of users use the air massage device 1, each user can more reliably fit the leg covering portion 30 to his / her lower leg, and can receive massage by the air bag depending on the state.

  (14) According to the boot 20, the leg opening 33 is formed so as to extend in the height direction of the leg covering portion 30. Therefore, the user can easily attach the boot 20 by opening the leg opening 33.

  (15) According to the boot 20, the foot opening 42 is formed so as to extend in the front-rear direction of the foot covering portion 40. Therefore, the user can easily wear the boot 20 by opening the foot opening 42.

  (16) According to the boot 20, the leg opening 33 and the leg opening 42 are formed so as to be continuous with each other. Therefore, the user can open the boot 20 from the upper edge of the leg covering portion 30 to the front edge of the foot covering portion 40. For this reason, the mounting property of the boot 20 is further improved.

  (17) According to the air massage device 1, the main part forming the skeleton of the boot 20 is constituted by the main fabric 21. For this reason, compared with the case where the main part of the boot 20 is formed by sewing a large number of fabrics, there are fewer stitched portions when the fabrics are three-dimensionally sewn. For this reason, the designability of the boot 20 is improved.

  (18) According to the air massage device 1, the stitching portion 26 is formed on the outsole 25 that is relatively difficult for the user to visually recognize compared with other portions of the boot 20, so that the design of the boot 20 is further enhanced. It is done.

  (19) The strength with which the leg fastening portions 31 and 32 fasten the leg covering portion 30 and the strength with which the foot fastening portion 41 fastens the foot covering portion 40 may be set to a preferable strength individually. preferable. On the other hand, the strength with which each leg tightening portion 31, 32 tightens the leg covering portion 30 varies depending on the area of each leg tightening portion 31, 32, and the strength with which the foot tightening portion 41 tightens the foot covering portion 40 is: It changes according to the area of the foot clamp part 41. For this reason, when it is going to set each intensity | strength to preferable intensity | strength, the area | region in which each leg fastening part 31 and 32 and the area | region in which the foot fastening part 41 is formed may mutually interfere. is there. For this reason, when the main part of the boot including the leg tightening portions 31 and 32 and the foot tightening portion 41 is formed of the same fabric, each leg tightening portion 31 and 32 is avoided in order to avoid the interference as described above. In addition, the area of one or both of the foot tightening portions 41 may need to be set to be narrower than the preferred area.

  On the other hand, according to the air massage apparatus 1, since the sub-fabric 23 formed separately from the main fabric 21 is used based on such matters, the respective areas of the leg tightening portions 31 and 32 and the foot tightening portion 41 are reduced. A preferable area can be set. For this reason, it is possible to set the strength at which the leg fastening portions 31 and 32 fasten the leg covering portion 30 and the strength at which the foot fastening portion 41 fastens the foot covering portion 40 to a preferable strength.

  (20) According to the air massage device 1, the foot side airbag 120 massages the lower part of the ankle, so that a more preferable massage feeling can be given to the user. Further, a foot tightening portion 41 is formed from a portion of the foot covering portion 40 facing the instep of the foot to a portion facing the side of the heel, which is a portion to which the foot side airbag 120 is attached. . For this reason, since all of the foot side airbag 120 is firmly pressed against the foot by the foot tightening portion 41, the feeling of massage given to the foot by the foot side airbag 120 is further improved.

  (21) According to the air massage device 1, the edge of the foot tightening portion 41 is formed so as to go from the inside of the instep to the outside of the instep as it goes from the instep side to the ankle side. According to the air massage device 1, since the edge of the foot tightening portion 41 is formed as described above, the ankle side portion of the foot tightening portion 41 exists in the outer portion of the foot. When tightening the foot clamp 41, it is easy to grasp that portion. For this reason, workability | operativity when fastening the leg fastening part 41 improves.

  (22) According to the user wearing the air massage device 1, the foot side airbag 120 causes the target portions that are inside and outside of the lower part of the ankle of the foot to be closer to the back of the heel and the back of the heel. Is also strongly massaged. Thus, according to the air massage device 1, when massaging a target part intended to be massaged strongly, a part near the target part is massaged weakly, or a part near the target part is massaged. Not. For this reason, compared with the case where the site | part containing a target site | part and its vicinity part is massaged strongly as a whole, the massage feeling which a user memorize | stores in a target site is emphasized. For this reason, a more preferable massage feeling can be given to a user compared with the case where a leg is massaged simply without intending to emphasize the massage feeling of an object part.

  (23) According to the air massage device 1, the number of supply ports for supplying air to the inner leg airbag 122, the outer leg airbag 121, and the second leg airbag 112 is set to one. Yes. For this reason, compared with the case where each said airbag 112, 121, 122 is mutually independent, it is easy to simplify the structure of an apparatus.

  (24) When the outer leg airbag 121, the inner leg airbag 122, and the second leg airbag 112 are independent from each other, their relative positional relationship is designed when the air massage device 1 is designed. There is a risk of deviating from the established relationship. Such a problem may occur, for example, when each air bag 112, 121, 122 is attached to the boot 20 during manufacture of the air massage device 1, or when the air massage device 1 is used. . On the other hand, in the air massage apparatus 1, each of the airbags 112, 121, and 122 constitutes a part of one airbag. For this reason, the relative positional relationship between the airbags 112, 121, and 122 is not easily deviated from the relationship designed when the air massage device 1 is designed.

  (25) According to the air massage device 1, the upper airbag 230 and the foot side airbag 120 can be inflated independently of each other, so that a variety of massage feelings can be given to the user. Further, when massaging the target part, the massage feeling of the target part is emphasized by weakening the force of massaging the upper part of the foot with the upper airbag 230 or by not massaging the upper part of the foot with the upper airbag 230. be able to.

  (26) According to the air massage device 1, the second sole air bag 212 and the foot side airbag 120 can be inflated independently of each other, so that a variety of massage feelings can be given to the user. it can. Further, when massaging the target part, the force of massaging the arch with the second sole air bag 212 is weakened, or the arch is not massaged with the second sole air bag 212, thereby massaging the target part. A feeling is emphasized.

  (27) As at least one of the leg airbag 110, the foot side airbag 120, the sole airbag 210, the inner airbag 220, and the upper airbag 230 inflates, the boot 20 A pulling force is applied. For this reason, in a state where the auxiliary tool 90 is inserted between the boot 20 and the lower limb, when such force acts on the boot 20, the auxiliary tool 90 is strongly pressed against the lower limb. For this reason, in addition to the air bag, the user also feels a massage at the portion where the auxiliary tool 90 is pressed. Moreover, since the position which inserts the auxiliary tool 90 can be set arbitrarily by the user, according to the air massage apparatus 1, various parts of the lower limb can be massaged by the auxiliary tool 90.

  (28) According to the present air massage device 1, the auxiliary tool 90 has the handle 93. For this reason, the user moves the position after inserting the auxiliary tool 90 between the boot 20 and the lower limb attached to the lower limbs, or takes out the inserted auxiliary tool 90 from between the boot 20 and the lower limbs. At this time, the auxiliary tool 90 can be handled using the handle 93. For this reason, the possibility that the user feels bothered with the handling of the auxiliary tool 90 is reduced.

  (29) The base 81 formed of a hard resin material is attached to the first leg airbag 111 so that the base 81 is disposed on the back side portion of the leg covering portion 30. For this reason, since the shape of the part of the back side of the boot 20 is hold | maintained by the base 81, the shape of the boot 20 becomes difficult to collapse and the design property is improved.

  (30) The wire harness 70 is routed around the back side portion of the leg covering portion 30 along the height direction. For this reason, since the shape of the part of the back side of the boot 20 is hold | maintained with the wire harness 70, the shape of the boot 20 becomes difficult to collapse and the design property is improved.
