[0009] (Embodiment) (1) Overview Each drawing described in the following embodiments is a schematic drawing, and the size and thickness ratios of each component in each drawing do not necessarily reflect the actual dimensional ratios.

[0010] As shown in Figs. 1 to 4, the air massage device 1 according to this embodiment includes an attachment 10 that is attached to a leg 900 of a user U1.

[0011] The attachment 10 includes at least one of an attachment 10R for the right leg that is attached to the right leg 900R of the user U1 and an attachment 10L for the left leg that is attached to the left leg 900L of the user U1.

[0012] The attachment 10 used as the right leg attachment 10R or the left leg attachment 10L includes at least a first attachment 11 attached to the lower leg 910 of the user U1, and a second attachment 12 attached to the thigh 920 of the user U1.

[0013] The first attachment 11 includes a first leg belt section 21 and a first airbag 31 (see FIG. 7). The first leg belt section 21 is formed into a bag shape by a first outer cloth 211 and a first inner cloth 212, and is wrapped around the lower leg section 910 of the user U1. The first airbag 31 is built into the first leg belt section 21.

[0014] The second attachment 12 has a second leg strap portion 22, a second airbag 32 (see FIG. 8), a first connecting portion 42, and a second connecting portion 44.

[0015] The second leg band portion 22 is formed into a bag shape by a second outer cloth 221 and a second inner cloth 222 and is wrapped around the thigh portion 920.

[0016] The second airbag 32 is housed in the second leg strap portion 22 .

[0017] The first connecting portion 42 detachably connects the first end 22A and the second end 22B of the second leg strap portion 22, and by connecting the first end 22A and the second end 22B, the second leg strap portion 22 is made cylindrical.

[0018] The second connecting portion 44 connects a portion of the first end 22A and a portion of the second end 22B of the second leg strap portion 22 when the connection by the first connecting portion 42 is released, thereby forming a portion of the second leg strap portion 22 into a ring shape.

[0019] The first leg strap portion 21 wound in a cylindrical shape is smaller than the annular portion of the second leg strap portion 22 formed in a circular shape by the second connecting portion 44. With the second leg strap portion 22 disposed on the outer periphery of the first leg strap portion 21 wound in a cylindrical shape, at least a portion of the first leg strap portion 21 wound in a cylindrical shape is disposed so as to overlap at least a portion of the second leg strap portion 22 formed in a circular shape.

[0020] In the description of this embodiment, the part of the leg 900 from the knee to the ankle is referred to as the lower leg 910, and the part on the back side of the lower leg 910 is referred to as the calf. The leg 900 includes the lower leg 910 and the thigh 920, and the part from the base of the leg to the knee (thigh) is referred to as the thigh 920. In addition, the part from the ankle to the toes is referred to as the foot 930.

[0021] When the air massage device 1 of this embodiment is not in use, the second leg strap portion 22 formed in a ring shape can be arranged on the outer periphery of the first leg strap portion 21 rolled up in a cylindrical shape, allowing the attachment 10 to be stored compactly.

[0022] Furthermore, when the second leg belt part 22, which has been developed into a cloth-like shape, is to be worn around the thigh part 920, it is necessary to hold the first end part 22A and the second end part 22B of the second leg belt part 22 with both hands and align and wrap the second leg belt part 22 around the desired position of the thigh part 920, which takes time and effort to wear the second leg belt part 22 around the thigh part 920. In contrast, in the air massage device 1 according to this embodiment, even when the connection between the first end part 22A and the second end part 22B by the first connection part 42 is released, the second connection part 44 connects a part of the first end part 22A to a part of the second end part 22B, so that the second leg belt part 22 is formed into a ring shape. Therefore, when the second leg strap portion 22 is attached to the thigh 920 of the user U1, if the leg 900 of the user U1 is passed through the ring-shaped portion of the second leg strap portion 22, the second leg strap portion 22 will not come off the leg 900 and can be moved to a desired position along the leg 900 of the user U1. Then, by connecting the first end portion 22A and the second end portion 22B with the first connecting portion 42, the second leg strap portion 22 can be attached to the thigh 920, so that an air massage device 1 that can reduce the effort of attachment can be provided. The second connecting portion 44 may always connect a part of the first end portion 22A to a part of the second end portion 22B.

[0023] (2) Details (2.1) Structure Hereinafter, the air massage device 1 according to this embodiment will be described in detail with reference to the drawings. In the following description, the up / down, left / right, and front / rear directions are defined based on the direction when the user U1 sees the attachment 10 in a state where the user U1 wears the attachment 10 on the leg 900.

[0024] In the air massage device 1 of this embodiment, the attachment 10 includes a right leg attachment 10R and a left leg attachment 10L. The user U1 can simultaneously massage the right leg 900R and the left leg 900L by attaching the right leg attachment 10R to the right leg 900R and the left leg attachment 10L to the left leg 900L.

[0025] Each of the right leg attachment 10R and the left leg attachment 10L further includes a third attachment 13 attached to a foot 930 of the user U1 in addition to the first attachment 11 and the second attachment 12. That is, the right leg attachment 10R and the left leg attachment 10L are attached to the leg 900 and the foot 930 of the user U1. The third attachment 13 includes a third leg belt part 23 wrapped around the foot 930, and a third airbag 33 (see FIG. 9) is built into the third leg belt part 23. In addition, each of the right leg attachment 10R and the left leg attachment 10L further includes a connecting belt 14 connecting the first attachment 11 and the second attachment 12 so that the first attachment 11 and the second attachment 12 can move relative to each other.

[0026] The air massage device 1 of this embodiment further includes an operating device 50 (see Figs. 1 and 11) provided with an operating section 53 and a display section 54, and the operating device 50 is provided on the left leg attachment 10L. As shown in Fig. 12, the air massage device 1 further includes an air pump 74, a plurality of three-way electromagnetic valves 75, a control section 57, a heater driving section 58, a power supply circuit 59, and heater blocks 76R and 76L. The control section 57, the heater driving section 58, and the power supply circuit 59 are housed in a housing 51 of the operating device 50. The air pump 74 and the plurality of three-way electromagnetic valves 75 are attached to the left leg attachment 10L. The heater blocks 76R and 76L are provided to heat the foot 930 of the user U1. The heater block 76R is disposed on the third attachment 13 of the attachment 10R for the right leg, and the heater block 76L is disposed on the third attachment 13 of the attachment 10L for the left leg.

[0027] The heater driving unit 58 supplies power to the heater blocks 76R and 76L in response to a control signal from the control unit 57, thereby causing the heater blocks 76R and 76L to generate heat.

[0028] The air pump 74 is, for example, a diaphragm pump. The air pump 74 transfers air by reciprocating a diaphragm with a motor in response to a control signal from the control unit 57. The air pump 74 sends air to the first airbag 31 and the second airbag 32 provided on the right leg attachment 10R and the left leg attachment 10L. In this embodiment, the right leg attachment 10R and the left leg attachment 10L further include a third airbag 33, so the air pump 74 also sends air to the third airbag 33 provided on the right leg attachment 10R and the left leg attachment 10L. The air pump 74 is provided on the attachment 10 (the left leg attachment 10L in this embodiment) on which the operation device 50 is provided, of the right leg attachment 10R and the left leg attachment 10L. Of the right leg attachment 10R and the left leg attachment 10L, the attachment 10 provided with the air pump 74 (the left leg attachment 10L in this embodiment) and the attachment 10 not provided with the air pump 74 (the right leg attachment 10R in this embodiment) are connected via an air hose (hose module 60) to which air is supplied from the air pump 74. Therefore, it is only necessary to connect the right leg attachment 10R and the left leg attachment 10L with a single bundle of air hoses (hose module 60), and the number of air hoses can be reduced compared to the case where the air pump 74 is housed in a housing separate from the right leg attachment 10R and the left leg attachment 10L.

[0029] The three-way solenoid valves 75 connect each of the airbags (first to third airbags 31 to 33) included in the air massage device 1 to the air pump 74 or the exhaust port in response to a control signal from the control unit 57, thereby inflating or deflating the airbags. A hose module 60 is led out from the right leg attachment 10R to connect between the airbags built in the right leg attachment 10R and the three-way solenoid valves 75 built in the left leg attachment 10L. The hose module 60 is configured by bundling a plurality of air hoses 61 to 66 (for example, six). The hose module 60 also bundles a power cord for supplying power to a heater block 76R provided in the right leg attachment 10R together with the air hoses 61 to 66. A plug 68 connectable to a connector 55 provided in the operation device 50 is provided at the tip of the hose module 60.

[0030] The operation unit 53 is provided for performing operations related to the massage performed using the air massage device 1. The operation unit 53 includes three operation buttons 53A to 53C provided on the housing 51 of the controller 50. The operation unit 53 includes, for example, an operation button 53A used for starting and stopping the massage and for setting the strength of the massage, an operation button 53B for switching the massage course, and an operation button 53C for setting the heating temperature by the heater blocks 76R and 76L. The number and uses of the operation buttons provided on the operation unit 53 can be changed as appropriate.

[0031] The display unit 54 includes a plurality of light emitting diodes 54A. The control unit 57 controls the lighting and extinguishing or the color of the light emitted by the plurality of light emitting diodes 54A to display the operating state of the air massage device 1. The display unit 54 includes the plurality of light emitting diodes 54A, but may also include a display device such as a liquid crystal display. The operating device 50 may also be provided with a speaker or the like for notifying the operating state of the air massage device 1 by voice or the like.

[0032] The control unit 57 mainly comprises, for example, a computer system having one or more processors and a memory. The functions of the control unit 57 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunication line such as the Internet, or may be provided by recording it on a non-transitory recording medium such as a memory card.

[0033] The control unit 57 controls the operation of the air pump 74 and the three-way solenoid valve 75 based on operation information input from the operation unit 53 in response to the operation of the user U1, thereby inflating or deflating the first to third airbags 31 to 33 to perform a massage. Also, based on operation information input from the operation unit 53 in response to the operation of the user U1, the control unit 57 controls the operation of the heater drive unit 58 that drives the heater blocks 76R, 76L, and controls the heating of the feet 930 by the heater blocks 76R, 76L.

[0034] The power supply circuit 59 receives power from, for example, an AC adapter 80 that converts AC voltage into DC voltage, and supplies power to the control unit 57, the display unit 54, the heater drive unit 58, the air pump 74, the three-way solenoid valve 75, etc. When the power supply circuit 59 supplies power to the control unit 57, the display unit 54, the heater drive unit 58, the air pump 74, the three-way solenoid valve 75, etc., the air massage device 1 becomes operable.

[0035] As described above, the air massage device 1 of this embodiment includes the right leg attachment 10R and the left leg attachment 10L. The right leg attachment 10R and the left leg attachment 10L are different in that the left leg attachment 10L is provided with the operating device 50 and the hose module 60 is led out from the right leg attachment 10R, but apart from these differences, they are symmetrical.

[0036] In the following, the attachment 10 will be described using the right leg attachment 10R as an example.

[0037] The first attachment 11 of the right leg attachment 10R is attached to a lower leg 910 of the right leg 900R of the user U1. The first attachment 11 includes a first leg strap portion 21 and a first airbag 31.

[0038] The first leg belt part 21 is formed into a bag shape by sewing a first outer cloth 211 made of synthetic fiber (such as polyester fiber) and a first inner cloth 212 made of synthetic fiber (such as nylon fiber). When the first leg belt part 21 is unfolded, the vertical dimension of the first leg belt part 21 is set to a dimension capable of covering the massage area of ​​the lower leg part 910, and the horizontal dimension of the first leg belt part 21 is set to a dimension longer than the average circumference of the lower leg part 910.

[0039] A hook 411 constituting a surface fastener is provided on the outer surface of the first end 21A on the right side of the first leg belt part 21 (i.e., the right end of the first outer cloth 211). A loop 412 constituting a surface fastener is provided on the inner surface of the second end 21B on the left side of the first leg belt part 21 (i.e., the left end of the first inner cloth 212). The hook 411 and the loop 412 are bonded together to connect the first end 21A and the second end 21B of the first leg belt part 21. That is, the hook 411 and the loop 412 form a connecting part 41 that connects the first end 21A and the second end 21B of the first leg belt part 21. When the first end 21A and the second end 21B of the first leg belt part 21 are connected by the connecting part 41, the first leg belt part 21 is formed into a cylindrical shape.

[0040] Here, it is preferable to partially pinch stitch the folded portion of the second end portion 21B. When the loop 412 is peeled off from the hook 411, the second end portion 21B is held in a folded-back state outward, reducing the possibility that the loop 412 will unintentionally stick to the hook 411. In order to temporarily hold the second end portion 21B in a folded-back state, a hook-and-loop fastener for temporary holding may be provided on the outer surface of the second end portion 21B and on the portion of the first outer cloth 211 where the outer surface of the second end portion 21B comes into contact. Since the hook-and-loop fastener holds the second end portion 21B in a folded-back state, it is possible to reduce the possibility that the loop 412 will unintentionally stick to the hook 411.

[0041] Further, horizontally long reinforcing members 27 are built into the second end 21B of the first leg strap portion 21, lined up above and below. The reinforcing members 27 are formed, for example, from synthetic resin in the shape of a horizontally long rectangular plate, making it easier for the second end 21B to maintain its shape in the longitudinal direction of the reinforcing members 27. The number, shape, and arrangement of the reinforcing members 27 can be changed as appropriate. Furthermore, it is not essential to provide the reinforcing members 27 in the first leg strap portion 21, and the reinforcing members 27 may be omitted as appropriate.

[0042] The first leg belt portion 21 includes a first airbag 31 for massaging the lower leg portion 910. FIG. 7 is a plan view showing an example of the first airbag 31. In this embodiment, the first airbag 31 includes an ankle airbag 311 for massaging the ankle and a calf airbag 312 for massaging the calf. When air is sent from the air pump 74 to the first airbag 31 (the ankle airbag 311 or the calf airbag 312), the first airbag 31 expands and compresses the lower leg portion 910. On the other hand, when the air filled in the first airbag 31 is discharged, the first airbag 31 contracts. The first airbag 31 repeatedly expands and contracts to massage the lower leg portion 910. It is not essential that the first airbag 31 includes two airbags for the ankle and the calf, and it may include one airbag or three or more airbags. It is preferable that cushioning material is placed on the first leg strap section 21 in the area covering the ankle, so that the first airbag 31 fits the shape of the lower leg 910 and the massage effect can be improved.

[0043] The first leg strap portion 21 has built-in support members 70 that are placed along the calves of the user U1 at the portions of the first leg strap portion 21 that cover the calves of the user U1 (see FIG. 2).

[0044] As shown in Figs. 10 and 11, the support component 70 is formed by joining an outer case 71 and an inner case 72, each of which is made of a synthetic resin molded product.

[0045] The outer case 71 is a plate material having an arc-shaped shape when viewed from above. The inner case 72 is a plate material having an arc-shaped shape when viewed from above, and is attached between the left side and the right side of the outer case 71. When the outer case 71 and the inner case 72 are joined together, a space for accommodating the air pump 74, the three-way solenoid valve 75, etc. is formed between the outer case 71 and the inner case 72. The inner surface of the inner case 72, i.e., the surface on the first inner cloth 212 side of the support component 70, includes a curved portion 721 that is convex backward and has a shape that fits the calf of the user U1, which has the advantage of making it easy to attach the first attachment 11.

[0046] In addition, a dome-shaped recess 722 is provided in the lower part of the inner case 72, so that when the user U1 wears the attachment 10, the heel of the user U1 is less likely to hit the inner surface of the inner case 72. In other words, the lower part of the support part 70 has a recess 722 for avoiding interference with the heel of the user U1, which has the advantage of making it easier to wear the first attachment 11.

[0047] Here, since the underside 73 of the support part 70 is formed in a C-shape, when the first attachment 11 incorporating the support part 70 is placed on a floor or the like, the C-shaped underside 73 prevents the support part 70 from falling over, and the attachment 10 can stand on its own.

[0048] A hose module 60 including a plurality of air hoses respectively connected to the first to third airbags 31 to 33 provided on the right leg attachment 10R is led out from the first leg strap section 21 of the right leg attachment 10R. A plug 68 connectable to a connector 55 provided on the operating device 50 is provided at the tip of the hose module 60. Here, when the user U1 wears the first attachment 11 of the right leg attachment 10R, the hose module 60 is led out from a portion of the first leg strap section 21 that corresponds to the left side of the lower leg section 910.

[0049] Further, the operating device 50 is attached to the upper part of the support part 70 built into the first attachment 11 of the left leg attachment 10L. Specifically, an attachment piece 723 protruding upward is provided on the upper part of the inner case 72, and the operating device 50 is fixed to the attachment piece 723 using a screw or the like. The support part 70 is mostly housed inside the first leg belt part 21, but the operating device 50 fixed to the attachment piece 723 of the support part 70 is exposed to the outside through an opening provided in the first leg belt part 21. In other words, the operating device 50 for performing operations related to massage is attached to the support part 70, and the operating device 50 is exposed on the surface of the first outer cloth 211. Note that, in this embodiment, the operating device 50 is attached to the support part 70 of the left leg attachment 10L, but the operating device 50 may be attached to the support part 70 of the right leg attachment 10R. In this way, since the operating device 50 is attached to the support member 70, the operating device 50 can be integrated with the right leg attachment 10R or the left leg attachment 10L, and the air massage device 1 can be made compact.

[0050] The controller 50 has a housing 51 made of synthetic resin and formed into a flat rectangular parallelepiped shape. The controller 50 (housing 51) has an operation surface 52 on the side opposite to the surface facing the support component 70. The operation surface 52 has a rectangular shape in a plan view, and a plurality of (for example, three) operation buttons 53A to 53C and a plurality of light-emitting diodes 54A are arranged on the operation surface 52. The housing 51 of the controller 50 is also provided with a connector 55 for connecting an air hose (hose module 60). Since the connector 55 for connecting the air hose (hose module 60) is integrated into the housing 51 of the controller 50, it is possible to reduce the protruding portion with which the second leg strap part 22 comes into contact when the second leg strap part 22 is arranged on the outer periphery of the first leg strap part 21, and the second leg strap part 22 can be smoothly overlapped on the outer periphery of the first leg strap part 21. Connector 55 is provided on the underside of housing 51 of controller 50, and air hose (hose module 60) is connected to connector 55 from below. As a result, air hose (hose module 60) connected to connector 55 extends downward from connector 55, reducing the possibility that air hose (hose module 60) will hit leg 900. In addition, even when air hose (hose module 60) is connected to connector 55, air hose (hose module 60) is led out downward, which has the advantage that air hose (hose module 60) is less likely to get in the way when second leg strap part 22 is placed over the outer periphery of first leg strap part 21.

[0051] Further, on the bottom surface of the controller 50, there is provided a pin jack 56 to which a pin plug 82 provided on a power cord 81 of an AC adapter 80, for example, can be connected.

[0052] In this embodiment, the hose module 60 is configured by bundling six air hoses connected to the first to third airbags 31 to 33 and a power cord for supplying power to a heater block 76R provided on the right leg attachment 10R. The plug 68 is provided with six first connection ports respectively connected to the six air hoses and a pin plug electrically connected to the power cord. The connector 55 is provided with a plurality of second connection ports respectively connected to the plurality of first connection ports provided on the plug 68 and a pin jack connected to the pin plug provided on the plug 68. Here, when the plug 68 is connected to the connector 55, the first to third airbags 31 to 33 provided on the right leg attachment 10R are connected to a plurality of three-way solenoid valves 75 provided on the left leg attachment 10L. Also, the heater block 76R provided on the right leg attachment 10R is electrically connected to a heater drive unit 58 provided on the left leg attachment 10L.

[0053] Here, the upper part of the operating device 50 (housing 51) is formed in a tapered shape that becomes thinner toward the upper side when viewed from the side. Since the thickness dimension D1 of the upper part of the housing 51 is formed to be smaller than the thickness dimension D2 of the lower part of the housing 51, when the annular part of the second attachment 12 is arranged on the outer periphery of the first attachment 11, the second attachment 12 is less likely to get caught on the housing 51 of the operating device 50. Therefore, there is an advantage that the work of arranging the annular part of the second attachment 12 on the outer periphery of the first attachment 11 is easy to perform. In addition, since the upper part of the housing 51 is formed in a tapered shape that becomes thinner toward the upper side, there is also an advantage that it is easier to operate the operation buttons 53A to 53C arranged on the operation surface 52, and it is easier to see the display by the light-emitting diode 54A.

[0054] Incidentally, since the mounting piece 723 protrudes upward from the right end portion of the upper part of the inner case 72, when the user U1 wears the left leg attachment 10L, the operating device 50 is located slightly to the right (closer to the inner thigh) of the back of the calf of the left leg. In other words, since the operating device 50 is located inside the part of the first leg band part 21 that covers the calf of the user U1, there is an advantage that the operating unit 53 provided on the operating device 50 is easy to operate and the display on the display unit 54 is easy to see. In addition, when the plug 68 of the hose module 60 is connected to the connector 55 of the operating device 50, the hose module 60 is located between the left part of the first leg band part 21 of the right leg attachment 10R and the right part of the first leg band part 21 of the left leg attachment 10L. Therefore, it is possible to reduce the possibility that the user U1 wearing the air massage device 1 will get caught on the hose module 60 when moving his / her leg. Also, since the length of the hose module 60 can be shortened, there is an advantage that the storage space required for storing the air massage device 1 can be reduced.

[0055] The second attachment 12 of the right leg attachment 10R is attached to a thigh 920 of the right leg 900R of the user U1. The second attachment 12 includes a second leg strap portion 22 and a second airbag 32.

[0056] The second leg belt part 22 is formed into a bag shape by sewing a second outer cloth 221 made of synthetic fiber (such as polyester fiber) and a second inner cloth 222 made of synthetic fiber (such as nylon fiber). The vertical dimension of the second leg belt part 22 is set to a dimension that can cover the massage area of ​​the thigh part 920. When the second leg belt part 22 is unfolded, the horizontal dimension of the second leg belt part 22 is set to a dimension longer than the average circumference of the thigh part 920.

[0057] A hook 421 constituting a surface fastener is provided on the outer surface of the first end 22A on the right side of the second leg belt part 22 (i.e., the right end of the second outer cloth 221). A loop 422 constituting a surface fastener is provided on the inner surface of the second end 22B on the left side of the second leg belt part 22 (i.e., the left end of the second inner cloth 222). The hook 421 and the loop 422 are bonded together to connect the first end 22A and the second end 22B of the second leg belt part 22. In other words, the hook 421 and the loop 422 form the first connecting part 42 that connects the first end 22A and the second end 22B of the second leg belt part 22. When the first end 22A and the second end 22B of the second leg belt part 22 are connected by the first connecting part 42, the second leg belt part 22 is formed into a cylindrical shape.

[0058] Here, it is preferable to partially pinch stitch the folded portion of the second end 22B. When the loop 422 is peeled off from the hook 421, the second end 22B is held in a folded-back state, so that the possibility of the loop 422 unintentionally sticking to the hook 421 can be reduced. In order to temporarily hold the second end 22B in a folded-back state, a hook-like fastener for temporary fastening may be provided on the outer surface of the second end 22B and the portion of the second outer cloth 221 where the outer surface of the second end 22B comes into contact. The hook-like fastener keeps the outer surface of the second end 22B folded back, so that the possibility of the loop 422 unintentionally sticking to the hook 421 can be reduced.

[0059] In addition, in the second leg strap section 22, the upper part of the first end 22A and the upper part of the second end 22B are connected via the second connecting part 44. That is, the upper part of the second leg strap section 22 is formed into a ring shape by the second connecting part 44 connecting the upper part of the first end 22A and the upper part of the second end 22B. Therefore, even when the connection by the first connecting part 42 is released, a part of the second leg strap section 22 (the upper part of the second leg strap section 22 in this embodiment) is kept in a ring shape by the second connecting part 44. Here, since the first leg strap section 21 wound in a cylindrical shape is smaller than the ring part 22C of the second leg strap section 22 formed in a ring shape by the second connecting part 44, the second leg strap section 22 can be arranged on the outer circumference of the first leg strap section 21 wound in a cylindrical shape. The second connecting part 44 is formed of a material having elasticity. The second connecting part 44 is realized by a woven rubber made of, for example, polyester fiber or polyurethane synthetic fiber. By stretching the second connecting part 44, the size of the annular part 22C of the second leg belt part 22 can be expanded, and the work of arranging the annular part 22C of the second leg belt part 22 on the outer periphery of the first leg belt part 21 can be easily performed. Note that the second connecting part 44 preferably has a certain width so as to be difficult to twist, and the width of the second connecting part 44 is preferably 30 to 60 mm, for example, and is 50 mm in this embodiment. In addition, the second connecting part 44 is preferably provided in the smallest range of the second leg belt part 22 excluding the part gripped by the user U1, and the center position of the second leg belt part 22 can be difficult to shift from the center of the thigh part 920. In addition, the second connecting part 44 may be configured to be detachable from at least one of the first end part 22A and the second end part 22B. The circumference of the upper end of the second leg strap portion 22 (the end toward the base of the thigh portion 920) is set to a dimension larger than the circumference of the lower end of the second leg strap portion 22 (the end toward the knee side of the thigh portion 920), making it easier for the second leg strap portion 22 to fit around the thigh portion 920.

[0060] The second leg belt portion 22 includes a second airbag 32 for massaging the thigh portion 920. FIG. 8 is a plan view showing an example of the second airbag 32. In this embodiment, the second airbag 32 includes an above-knee airbag 321 for massaging the area above the knee, a back-of-knee / back-of-thigh airbag 322 for massaging the area behind the knee and the area behind the thigh, and an above-thigh airbag 323 for massaging the upper side of the thigh. In the second airbag 32, a nozzle to which an air hose is connected is provided at a position corresponding to the side of the thigh portion 920, and there is an advantage that the nozzle is unlikely to get in the way when performing a massage or when attaching and detaching the second attachment 12. It is not essential that the second airbag 32 includes three airbags, and it may include one or two airbags, or may include four or more airbags.

[0061] Inside the second leg strap portion 22, a vertically long reinforcing member 25 is built in the tip of the first end portion 22A and the bent portion of the second end portion 22B. In addition, horizontally long reinforcing members 26 are built in the second end portion 22B in a vertically long rectangular plate shape. The reinforcing member 25 is formed, for example, from a synthetic resin, so that the second leg strap portion 22 can easily maintain its shape in the longitudinal direction of the reinforcing member 25. In addition, each of the two reinforcing members 26 is formed, for example, from a synthetic resin, so that the second end portion 22B of the second leg strap portion 22 can easily maintain its shape in the longitudinal direction of the reinforcing member 26. Thus, in this embodiment, the right leg attachment 10R and the left leg attachment 10L each have reinforcing members 25, 26 built in at the portion of the second leg strap portion 22 that covers the thigh 920 of the user U1. The reinforcing members 25, 26 maintain the shape of the second leg strap section 22, which reduces the effort required to put on and take off the second leg strap section 22 and also has the advantage of making it easier to arrange the second leg strap section 22 around the outer periphery of the first leg strap section 21. The number, shape and arrangement of the reinforcing members 25, 26 can be changed as appropriate. Also, it is not essential to provide the reinforcing members 25, 26 on the second leg strap section 22, and the reinforcing members 25, 26 may be omitted as appropriate.

[0062] Here, the lower part of the second leg belt part 22 of the second attachment 12 is connected to the first leg belt part 21 of the first attachment 11 via the connecting belt 14. The connecting belt 14 connects the first attachment 11 and the second attachment 12 so that the first attachment 11 and the second attachment 12 can move relatively to each other. Specifically, the connecting belt 14 connects the first leg belt part 21 and the second leg belt part 22 at the rear side of the leg 900 of the user U1. The connecting belt 14 is formed by sewing an outer cloth and an inner cloth into a bag shape, and the first leg belt part 21, the connecting belt 14 and the second leg belt part 22 are formed integrally. Since the first attachment 11 and the second attachment 12 are connected by a connecting strap 14, the first attachment 11 and the second attachment 12 do not come apart, and it is possible to judge whether the second attachment 12 is attached at an appropriate position by whether the connecting strap 14 is twisted or not.

[0063] An air hose for sending air to the second airbag 32 of the second attachment 12 passes through the inside of the connecting belt 14, which has the advantage that the air hose does not get in the way when overlapping the second leg belt part 22 over the outer periphery of the first leg belt part 21, making the work easier. Another advantage is that the air hose passes through the inside of the connecting belt 14, which improves the appearance.

[0064] The length of the connecting strap 14 is set to a dimension that allows the first leg strap part 21 and the second leg strap part 22 to be connected together when the first leg strap part 21 is wrapped around the lower leg part 910 and the second leg strap part 22 is wrapped around the thigh part 920. Therefore, from a state in which the foot 930 and the lower leg part 910 of the user U1 are inserted into the third attachment 13 and the first attachment 11 that form a boot shape, the second attachment 12 arranged on the outer periphery of the first attachment 11 is moved to the thigh part 920 of the user U1, so that the second attachment 12 is attached to the thigh part 920 of the user U1. Here, "forming a boot shape" refers to maintaining a state in which the lower leg attachment 11 protrudes upward from a support surface such as a floor when the foot attachment 13 is placed on the support surface, and refers to maintaining a shape like an integrated boot with the foot attachment 13 and the lower leg attachment 11.

[0065] In addition, the foot 930 and the lower leg 910 of the user U1 are inserted into the third attachment 13 and the first attachment 11 forming a boot shape, and the second attachment 12 is attached to the thigh 920 of the user U1. By moving the second attachment 12 to the lower leg 910 of the user U1, the second attachment 12 is placed on the outer periphery of the first attachment 11. At this time, the connecting belt 14 is placed between the first leg belt part 21 and the second leg belt part 22 placed on the outer periphery of the first leg belt part 21. Here, the length of the connecting belt 14 is set so that the lower end of the connecting belt 14 does not rub against the floor on which the air massage device 1 is placed. In addition, since the second leg strap section 22 is moved with the annular portion 22C of the second leg strap section 22 passed through the leg 900, the second leg strap section 22 is less likely to come off the leg 900 when moved, which has the advantage of making it easier to move the second leg strap section 22.

[0066] The third attachment 13 of the right leg attachment 10R is attached to the foot 930 of the right leg 900R of the user U1. The third attachment 13 includes a third leg strap part 23 that is wrapped around the foot 930 of the user U1, and a third airbag 33 (see Figures 9 and 12) built into the third leg strap part 23.

[0067] The third leg strap section 23 is formed into a bag shape by sewing a third outer cloth 231 made of synthetic fiber (such as polyester fiber) and a third inner cloth 232 made of synthetic fiber (such as nylon fiber). The first attachment 11 (first leg strap section 21) and the third attachment 13 (third leg strap section 23) are connected at the heel side of the foot 930 of the user U1, and the third leg strap section 23 and the first leg strap section 21 are formed integrally. Here, the first attachment 11 and the third attachment 13 around which the first leg strap section 21 is rolled up in a cylindrical shape form a boot, and the second leg strap section 22 is disposed on the outer periphery of the first leg strap section 21 forming the boot shape. Since the first attachment 11 and the third attachment 13 form the boot shape, the attachment 10 can be placed on the floor or the like in a self-supporting state.

[0068] The size of the third leg strap section 23 is set to a size that can cover the foot 930 of the user U1. The third leg strap section 23 includes a central section 23C on which the foot 930 of the user U1 is placed, a first end section 23A, and a second end section 23B. The first end section 23A is folded back from the right end section of the central section 23C to cover a part of the front side of the foot 930. The second end section 23B is folded back from the left end section of the central section 23C and affixed to the upper surface of the first end section 23A. Here, a pocket section into which the toes are inserted is provided by sewing the toe section of the first end section 23A to the central section 23C.

[0069] It is preferable that the central portion 23C of the third leg belt portion 23 is provided with a tray on which the heel of the foot 930 is placed. By placing the heel on the tray provided in the central portion 23C and inserting the toe into the pocket at the tip of the third leg belt portion 23, the foot 930 can be easily positioned, and the operation of putting the third leg belt portion 23 on the foot 930 can be easily performed. In addition, a heater block 76R is arranged in the central portion 23C of the third leg belt portion 23, and the foot 930 can be heated by the heater block 76R. In addition, the central portion 23C of the third leg belt portion 23 is provided with a pocket for accommodating a sole pad having an upward protrusion. By placing the sole pad in the pocket, the foot 930 can be stimulated by the protrusion of the sole pad when massaging the foot 930.

[0070] A hook 431 constituting a surface fastener is provided on the outer surface of the first end 23A on the right side of the third leg strap part 23. A loop 432 constituting a surface fastener is provided on the inner surface of the second end 23B on the left side of the third leg strap part 23. The hook 431 and the loop 432 are attached together to connect the first end 23A and the second end 23B of the third leg strap part 23. In other words, the hook 431 and the loop 432 form the connecting part 43 that connects the first end 23A and the second end 23B of the third leg strap part 23.

[0071] The third leg belt portion 23 has a third airbag 33 built therein for massaging the feet 930. FIG. 9 is a plan view showing an example of the third airbag 33. When air is sent from the air pump 74 to the third airbag 33, the third airbag 33 expands and compresses the feet 930. On the other hand, when the air filled in the third airbag 33 is discharged, the third airbag 33 contracts. The third airbag 33 repeatedly expands and contracts, thereby massaging the feet 930. Note that the third airbag 33 includes one airbag, but the third airbag 33 may include two or more airbags.

[0072] (2.2) Instructions for use A method of using the air massage device 1 of this embodiment will be described with reference to Figs. 5, 6, 13, 14, etc.

[0073] 5 and 6 show the right leg attachment 10R and the left leg attachment 10L in a stored state. In the stored state, the second end 23B is placed over the first end 23A of the third leg strap part 23, and the hook 431 is attached to the loop 432. The loop 412 provided on the second end 21B of the first leg strap part 21 is peeled off from the hook 411 provided on the first end 21A, and the second end 21B is folded back to the outside. Since the tip of the first end 21A is not connected to the second end 21B, the first leg strap part 21 is not formed into a complete cylindrical shape, but is held in a cylindrically wound state. The second leg strap part 22 is arranged on the outer periphery of the cylindrically wound first leg strap part 21. Here, the loop 422 of the second leg strap part 22 is released from the hook 421, and only the upper part of the second leg strap part 22 is formed into a ring shape by the second connecting part 44, and the lower part of the second leg strap part 22 is in an expanded state. When this second leg strap part 22 is placed on the outer periphery of the first leg strap part 21, the second leg strap part 22 is held in a state in which it is disposed on the outer periphery of the first leg strap part 21.

[0074] In addition, the first leg strap section 21 has a built-in support part 70 with a C-shaped underside 73, which prevents the first leg strap section 21 from falling over and allows the first leg strap section 21 and the third leg strap section 23 to form a boot shape that allows the attachment 10 to stand on its own. In the stored state, the attachment 10 can be placed on the floor or the like in a self-supporting state like a boot, allowing the attachment 10 to be stored compactly.

[0075] Next, the procedure for putting on the attachment 10 will be described. As shown in Fig. 13, the user U1 puts the foot 930 into the first leg strap part 21 of the attachment 10 in the stored state (the illustrated example is the left leg attachment 10L), inserts the foot 930 up to the third leg strap part 23, and inserts the lower leg part 910 into the first leg strap part 21. Here, since the first leg strap part 21 has the support part 70 built in, the foot 930 can be inserted by holding the part where the support part 70 is located, and since the support part 70 functions as a shoe spatula, the foot 930 can be inserted smoothly.

[0076] Thereafter, the user U1 pulls up the second leg strap section 22 arranged around the outer periphery of the first leg strap section 21 toward the thigh section 920, thereby moving the second leg strap section 22 to the thigh section 920 (see FIG. 14).

[0077] Here, the second inner cloth 222 of the second leg belt part 22 has a semispherical protrusion in the center thereof, and the user U1 adjusts the position of the second leg belt part 22 so that this protrusion coincides with the center of the thigh part 920. The user U1 adjusts the joining position of the first end part 22A and the second end part 22B of the second leg belt part 22 according to the thickness of his / her thigh part 920, and joins the first end part 22A and the second end part 22B by attaching the hook 421 to the loop 422.

[0078] In addition, the user U1 adjusts the joining position of the first end 21A and the second end 21B of the first leg belt part 21 according to the thickness of the user's lower leg part 910, and joins the first end 21A and the second end 21B by attaching the hook 411 to the loop 412. Here, a tag 24 (see Figs. 3 and 4) is provided at the center position in the up-down direction at the tip part of the first end 21A, and the user U1 holds the vicinity of the tag 24 of the first end 21A and attaches it to the second end 21B. This has the advantage that the first end 21A and the second end 21B are attached at the appropriate position, so that the hook 411 and the loop 412 can be firmly joined, and the first end 21A and the second end 21B are less likely to come off.

[0079] Finally, the user U1 adjusts the joining position between the first end 23A and the second end 23B of the third leg strap portion 23 to fit the size of his / her foot 930, and joins the first end 23A and the second end 23B by attaching the hook 431 to the loop 432.

[0080] This allows the user U1 to attach the first leg strap section 21, the second leg strap section 22, and the third leg strap section 23 to his / her own leg 900 and foot 930. After the user U1 attaches the left leg attachment 10L and the right leg attachment 10R to the left and right legs 900 and feet 930, respectively, the user U1 connects the hose module 60 drawn out from the right leg attachment 10R to the connector 55 of the controller 50 provided on the left leg attachment 10L. In addition, the user U1 connects the pin plug 82 of the AC adapter 80 to the pin jack 56 of the controller 50, and then connects the AC adapter 80 to an outlet to make the air massage device 1 ready for use.

[0081] Thereafter, the user U1 can operate the operation buttons 53A to 53C of the operation device 50 to massage the legs 900 at desired locations and with desired intensity.

[0082] Next, a procedure in which the user U1 takes off the attachment 10 and stores the air massage device 1 after finishing the massage using the air massage device 1 will be described.

[0083] When the user U1 takes off the attachment 10, the user U1 first removes the loop 422 provided on the second leg belt part 22 of the second attachment 12 from the hook 421, so that only the upper part of the second leg belt part 22 is formed into a ring shape by the second connecting part 44. When the loop 422 is removed from the hook 421 and the second end part 22B is folded back outward, the folded back part of the second end part 22B is held in the folded back state by the pinched stitch. Also, since only the upper part of the second leg belt part 22 is connected by the second connecting part 44, the lower side of the second leg belt part 22 can be spread out.

[0084] Next, the user U1 peels off the loop 412 provided on the first leg strap part 21 of the first attachment 11 from the hook 411, and folds the second end part 21B outward. Since the folded part of the second end part 21B is tucked, the second end part 21B is held in the folded outward state. At this time, the first leg strap part 21 is not in a closed cylindrical shape, but is formed in a substantially cylindrical shape.

[0085] Then, the user U1 moves the second leg strap portion 22 attached to the thigh portion 920 to the lower leg portion 910, and places the second leg strap portion 22, whose upper portion is formed in a ring shape, around the outer circumference of the first leg strap portion 21, which is rolled up in a cylindrical shape.

[0086] Then, the user U1 peels off the second end 23B of the third leg belt part 23 of the third attachment 13 from the first end 23A, and in a state in which the third leg belt part 23 is loosened, pulls out the leg 900 and the foot 930 from the attachment 10. When the user U1 pulls out the leg 900 and the foot 930 from the attachment 10, the second end 23B of the third leg belt part 23 is placed on the first end 23A and connected by the connecting part 43, and the second end 22B of the second leg belt part 22 is placed on the first end 22A and connected by the second connecting part 44. As a result, the attachment 10 is formed in a boot shape and is self-supporting by the support part 70 built into the first leg belt part 21. Therefore, when the air massage device 1 is not in use, the right leg attachment 10R and the left leg attachment 10L can be placed on the floor or the like like boots, and can be stored compactly.

[0087] (3) Variations Modifications of the above embodiment are listed below. The modifications described below can be applied in appropriate combinations.

[0088] Although the air massage device 1 of the above embodiment includes a plurality of airbags, the number and positions of the airbags can be appropriately changed depending on the part to be massaged.

[0089] The air massage device 1 of the above embodiment includes the heater blocks 76R, 76L for heating the feet 930 of the user U1, but may include heater blocks for heating the lower legs 910 or the thighs 920. In the air massage device 1, the heater blocks 76R, 76L are not essential components, and the heater blocks 76R, 76L can be omitted as appropriate.

[0090] In the air massage device 1 of the above embodiment, the first leg belt part 21 of the lower leg attachment 11 may be provided with a pocket for accommodating a shin pad provided with protrusions for pressing the shins. By performing a massage with the shin pad placed in the pocket of the first leg belt part 21, the protrusions of the shin pad can stimulate the shins, enhancing the massage effect.

[0091] (summary) As described above, the air massage device (1) of the first embodiment includes the attachment (10) attached to the leg (900) of the user (U1). The attachment (10) includes at least one of a right leg attachment (10R) attached to the right leg (900R) of the user (U1) and a left leg attachment (10L) attached to the left leg (900L) of the user (U1). The attachment (10) used as the right leg attachment (10R) or the left leg attachment (10L) includes at least a first attachment (11) attached to the lower leg (910) of the user (U1) and a second attachment (12) attached to the thigh (920) of the user (U1). The first attachment (11) includes a first leg belt portion (21) and a first airbag (31) built into the first leg belt portion (21). The first leg belt portion (21) is formed into a bag shape by a first outer cloth (211) and a first inner cloth (212) and is wrapped around the lower leg portion (910). The second attachment (12) includes a second leg belt portion (22), a second airbag (32), a first connecting portion (42), and a second connecting portion (44). The second leg belt portion (22) is formed into a bag shape by a second outer cloth (221) and a second inner cloth (222) and is wrapped around the thigh portion (920). The second airbag (32) is built into the second leg belt portion (22). The first connecting part (42) detachably connects the first end (22A) and the second end (22B) of the second leg strap part (22) and forms the second leg strap part (22) into a cylindrical shape by connecting the first end (22A) and the second end (22B). The second connecting part (44) connects a part of the first end (22A) and a part of the second end (22B) of the second leg strap part (22) in a state where the connection by the first connecting part (42) is released, thereby forming a part of the second leg strap part (22) into a ring shape. The first leg strap part (21) rolled into a cylindrical shape is smaller than the ring-shaped part (22C) of the second leg strap part (22) formed into a ring shape by the second connecting part (44). With the second leg strap portion (22) positioned on the outer periphery of the first leg strap portion (21) wound in a cylindrical shape, at least a portion of the first leg strap portion (21) wound in a cylindrical shape is positioned to overlap at least a portion of the second leg strap portion (22) formed in a ring shape.

[0092] According to this embodiment, even when the first end (22A) and the second end (22B) are released from the connection by the first connection part (42), the second connection part (44) connects a part of the first end (22A) and a part of the second end (22B), so that the second leg belt part (22) is formed in a ring shape. When the second leg belt part (22) is attached to the thigh part (920) of the user (U1), if the leg (900) of the user (U1) is passed through the ring part (22C) of the second leg belt part (22), the second leg belt part (22) does not come off the leg (900) and the second leg belt part (22) can be moved to a desired position along the leg (900) of the user (U1). Therefore, it is possible to provide an air massage device (1) that can reduce the effort required for attachment.

[0093] In the air massage device (1) of the second embodiment, in the first embodiment, the attachment (10) further includes a third attachment (13) to be attached to the foot (930). The first attachment (11) and the third attachment (13) are connected to each other at the heel side of the foot (930) of the user (U1). The first leg strap part (21) is wound in a cylindrical shape around the first attachment (11) and the third attachment (13) to form a boot shape, and the second leg strap part (22) is disposed on the outer periphery of the first leg strap part (21) forming the boot shape.

[0094] According to this embodiment, the first attachment (11) and the third attachment (13) form a boot shape, so that the attachment (10) can be placed on the floor or the like in a self-supporting state.

[0095] The air massage device (1) of the third aspect further includes a connecting strap (14) that connects the first attachment (11) and the second attachment (12) so that the first attachment (11) and the second attachment (12) can move relatively to each other. From a state in which the foot (930) and the lower leg (910) of the user (U1) are inserted into the third attachment (13) and the first attachment (11) that form a boot shape, the second attachment (12) arranged on the outer periphery of the first attachment (11) is moved to the thigh (920) of the user (U1), whereby the second attachment (12) is attached to the thigh (920) of the user (U1). The user's (U1) foot (930) and lower leg (910) are inserted into the third attachment (13) and the first attachment (11) which form the boot shape, and the second attachment (12) is attached to the user's (U1) thigh (920), and then the second attachment (12) is moved to the user's (U1) lower leg (910) so that the second attachment (12) is positioned on the outer periphery of the first attachment (11).

[0096] According to this embodiment, the second leg strap part (22) is moved with the annular portion (22C) of the second leg strap part (22) passed over the leg (900), which has the advantage that the second leg strap part (22) is less likely to come off the leg (900) when moved, making it easier to move the second leg strap part (22).

[0097] In the air massage device (1) of the fourth aspect, in any one of the first to third aspects, the attachment (10) includes an attachment for the right leg (10R) and an attachment for the left leg (10L). Each of the attachment for the right leg (10R) and the attachment for the left leg (10L) includes a support part (70) disposed along the calf of the user (U1) at a portion of the first leg band part (21) that covers the calf of the user (U1).

[0098] According to this embodiment, the first leg strap portion (21) can be made to stand on its own by the support part (70).

[0099] In the fifth aspect of the air massage device (1), in the fourth aspect, reinforcing members (25, 26) are built into each of the right leg attachment (10R) and the left leg attachment (10L) in the second leg strap portion (22) at the portions that cover the thighs of the user (U1).

[0100] According to this embodiment, the reinforcing members (25, 26) make it easier to maintain the shape of the second leg strap portion (22), and the effort required to put on and take off the second leg strap portion (22) can be reduced.

[0101] In the air massage device (1) of the sixth embodiment, in the fourth or fifth embodiment, an operating device (50) for performing operations related to massage is attached to the support member (70) of either the right leg attachment (10R) or the left leg attachment (10L). The operating device (50) is exposed on the surface of the first outer cloth (211).

[0102] According to this embodiment, the operating device (50) can be integrated with the right leg attachment (10R) or the left leg attachment (10L), thereby making it possible to reduce the size of the air massage device (1).

[0103] In the air massage device (1) of the seventh embodiment, the upper part of the operating device (50) in the sixth embodiment is formed in a tapered shape that becomes thinner toward the upper side.

[0104] This embodiment has the advantage that when the annular portion (22C) of the second leg strap (22) is arranged on the outer periphery of the first leg strap (21), the second leg strap (22) is less likely to get caught on the operating device (50).

[0105] In the air massage device (1) of the eighth aspect, in the sixth or seventh aspect, the attachment (10) for the right leg (10R) and the attachment (10L) for the left leg to which the operating device (50) is provided is provided with an air pump (74). The air pump (74) sends air to the first air bag (31) and the second air bag (32). The attachment (10) for the right leg (10R) and the attachment (10L) for the left leg to which the air pump (74) is provided is connected to the attachment (10) not provided with the air pump (74) via air hoses (61-66) to which air is supplied from the air pump (74).

[0106] According to this embodiment, it is only necessary to connect the right leg attachment (10R) and the left leg attachment (10L) with the air hoses (61-66), and the number of air hoses can be reduced compared to a case in which the air pump (74) is housed in a housing separate from the right leg attachment (10R) and the left leg attachment (10L).

[0107] In the air massage device (1) of the ninth aspect, in the eighth aspect, a connector (55) for connecting the air hoses (61-66) is provided to the housing (51) of the operation unit (50).

[0108] According to this embodiment, the connector (55) for connecting the air hoses (61-66) is integrated with the housing (51) of the operating device (50), so that it is possible to reduce the number of protruding portions with which the second leg strap (22) comes into contact when placing the second leg strap (22) on the outer periphery of the first leg strap (21). Thus, the second leg strap (22) can be smoothly placed on the outer periphery of the first leg strap (21).

[0109] In the air massage device (1) of the tenth aspect, in the ninth aspect, the connector (55) is provided on the lower surface of the housing (51) of the operation unit (50), and the air hoses (61-66) are connected to the connector (55) from below.

[0110] According to this embodiment, the air hoses (61-66) connected to the connector (55) are led out downward from the connector (55), thereby reducing the possibility that the air hoses (61-66) will hit the legs (900).

[0111] In the air massage device (1) of the eleventh aspect, in any one of the first to tenth aspects, the second connecting portion (44) is made of a stretchable material.

[0112] According to this embodiment, the second connecting portion (44) can be expanded to expand the size of the annular portion (22C) of the second leg strap portion (22), making it easy to position the annular portion (22C) of the second leg strap portion (22) around the outer periphery of the first leg strap portion (21).
