Description

Technical Field

[0001] The present disclosure relates to an air massage device. More specifically, the present disclosure relates to an air massage device for massaging the legs.

Background Art

[0002] Patent Document 1 discloses a chair-type air massager equipped with leg massagers. This leg massager includes a pair of leg bags that massage both legs by expanding and contracting due to the supply and exhaust of air, a surrounding member provided to surround the outer periphery of the leg bags, a buffer member provided to surround the outer periphery of the surrounding member, and a cover member provided to surround the outer periphery of the buffer member.

[0003] The leg bags are composed of a pair of flat bags that face each other and expand and contract by the supply and exhaust of air. The surrounding member is composed of a non-stretchable cloth-like member that surrounds the outer periphery of the bags. The buffer member is composed of, for example, a sponge-like member having elasticity, that is, buffering properties. The cover member is composed of cloth or the like.

[0004] The space formed on the inner peripheral surface of the bag forms an insertion hole through which the leg is inserted, and the inner peripheral surface serves as a pressing surface that presses the leg for massage. An opening and closing member made of a fastener or the like is provided at the opening edge of the opening of the cover member, and the opening of the cover member is opened and closed by this opening and closing member. Further, the opening of the insertion hole of the leg bag is closed by the cover member, preventing foreign matter from entering the insertion hole and preventing dirt inside the insertion hole.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In the above-described leg massager, the buffer member is composed of a sponge-like member having elasticity and has self-shaping properties. If the opening of the cover member is not closed by the opening / closing member, the opening of the insertion hole of the leg bag body is not closed. For this reason, simply pulling the leg out of the leg bag body does not close the insertion hole of the leg bag body, and it is difficult to reduce the size of the leg massager when not in use or during storage.

[0007] According to the present disclosure, it is possible to provide an air massager device that can easily be reduced in size (particularly, made thinner) when the airbag is not in use or during storage.

Means for Solving the Problems

[0008] An air massager device according to an aspect of the present disclosure includes an air supply device, two bag bodies, and an outer member. The air supply device supplies air to the airbag. The two bag bodies have the airbag that expands and contracts by air supply and exhaust. The bag body has an opening through which the user's leg can enter and exit at both ends in the direction of entry and exit of the leg, and a mounting member for mounting to the outer member. The mounting member is disposed at the central portion of the bag body in a direction orthogonal to the direction of entry and exit.

Effects of the Invention

[0009] According to the present disclosure, it is possible to provide an air massager device that can easily be reduced in size (particularly, made thinner) when the airbag is not in use or during storage.

Embodiments for Carrying Out the Invention

[0011] (1) Overview As shown in FIG. 1, the air massage device 1 massages the leg portion 90 of a user lying on the floor. As shown in FIG. 3, the air massage device 1 includes a drive system 2 and an outer member 5. The drive system 2 has an air supply device 20 and two bag bodies 4. The air supply device 20 supplies air to the airbag 3. The two bag bodies 4 have an airbag 3 that expands and contracts by air supply and exhaust. The two bag bodies 4 have openings 41 through which the user's leg portion 90 can enter and exit at both ends in the entry and exit direction (front-rear direction) of the leg portion 90. The outer member 5 is formed in a deformable bag shape and encloses the bag body 4. The outer member 5 has an inlet 51 at the upstream end (front side) in the entry and exit direction, which can be opened and closed and through which the leg portion 90 can enter and exit. As shown in FIG. 2, the outer member 5 is configured such that the inlet 51 closes due to the self-weight of the outer member 5 when the leg portion 90 is not inserted.

[0012] Thereby, miniaturization and thinning of the air massage device 1 when not in use are achieved, and the storage space of the air massage device 1 does not increase. Further, even if the air massage device 1 is left on the bed, it does not get in the way, and it becomes easier to sleep with the leg portion 90 placed on the air massage device 1.

[0013] (2) First Embodiment Hereinafter, the air massage device according to the first embodiment will be described in detail with reference to FIGS. 1 to 10.

[0014] (2.1) Overall Structure FIG. 1 shows a perspective view of the air massage device 1 with the user's leg 90 inserted, and FIG. 2 shows a perspective view of the air massage device 1 with the user's leg 90 not inserted.

[0015] As shown in FIG. 1, the air massage device 1 mainly massages the user's leg 90. In the present disclosure, the part of the body's leg 90 from the knee to the ankle is referred to as the lower leg 91, and the part on the rear side of the lower leg 91 is referred to as the calf. The leg 90 includes the lower leg 91 and the thigh, and the part from the base of the leg to the knee (thigh) is referred to as the thigh. Also, the part from the ankle to the toe tip is referred to as the foot 92.

[0016] The air massage device 1 is designed assuming that it massages the user's leg 90 (especially the lower leg 91) of a user lying supine on the floor. In this assumption, the user may lie the whole body on the floor, or raise the upper body with respect to the floor and lie only the lower body on the floor. At least, use in a state where the leg 90 is laid on the floor without bending the knees is assumed.

[0017] The air massage device 1 includes a main body part 10 and a foot cover 7. As shown in FIG. 3, the main body part 10 includes a drive system 2, a housing 11, and an outer member 5. The main body part 10 serves as a massage part that massages the user's lower leg 91.

[0018] (2.2) Drive System The drive system 2 has an air supply device 20 and at least two (four in the first embodiment) bag bodies 4.

[0019] (2.2.1) Air Supply Device Figures 3 to 7 show the air supply device 20. The air supply device 20 supplies air to at least two (four in the first embodiment) airbags 3. The air supply device 20 includes a heater drive unit 21, an air pump 22, a solenoid valve 23, an operation unit 24, a display unit 25, a control unit 26, and a power supply circuit 27.

[0020] The heater drive unit 21 supplies power to a heater 76 provided on a foot cover 7 described later in response to a control signal from the control unit 26, thereby causing the heater 76 to generate heat.

[0021] The air pump 22 is, for example, a diaphragm pump. The air pump 22 transfers air by reciprocating a diaphragm with a motor in response to a control signal from the control unit 26. The air pump 22 sends air into the airbag 3.

[0022] The solenoid valve 23 is a three-way solenoid valve. In the first embodiment, the air supply device 20 has four solenoid valves 23, namely, a first solenoid valve 23A to a fourth solenoid valve 23D corresponding to each airbag 3. The solenoid valve 23 has three ports, two of which are respectively connected to the air pump 22 and the corresponding airbag 3, and the remaining one port is open to the atmosphere. The solenoid valve 23 connects each of the plurality of airbags 3 provided in the air massage device 1 to the air pump 22 or the exhaust port in response to a control signal from the control unit 26, thereby inflating or deflating the plurality of airbags.

[0023] The operation unit 24 is provided for performing operations related to massage performed using the air massage device 1. The operation unit 24 has a plurality of operation buttons. The operation unit 24 includes, for example, operation buttons that are also used for operations such as starting and stopping massage and setting the massage strength, operation buttons for switching the massage course, and operation buttons for setting the heating temperature by the heater 76. Note that the number and uses of the operation buttons provided in the operation unit 24 can be changed as appropriate.

[0024] The display unit 25 includes a plurality of light-emitting diodes. By controlling the lighting, extinguishing, or emission color of the plurality of light-emitting diodes by the control unit 26, the operating state of the air massage device 1 is displayed. Note that although the display unit 25 includes a plurality of light-emitting diodes, it may be provided with a display device such as a liquid crystal display. Further, the air supply device 20 may be provided with a speaker or the like for notifying the operating state of the air massage device 1 by voice or the like.

[0025] The control unit 26 mainly includes, for example, a computer system having one or more processors and a memory. The functions of the control unit 26 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The control unit 26 is provided on the substrate 260. The program may be recorded in the memory, may be provided through an electric communication line such as the Internet, or may be provided by being recorded in a non-transitory recording medium such as a memory card.

[0026] The control unit 26 controls the operations of the air pump 22 and the solenoid valve 23 based on the operation information input from the operation unit 24 according to the user's operation, thereby expanding or contracting the airbag 3 to perform massage. Further, the control unit 26 controls the operation of the heater driving unit 21 that drives the heater 76 based on the operation information input from the operation unit 24 according to the user's operation, and controls the heating of the foot portion 92 by the heater 76.

[0027] The power supply circuit 27 receives power supply from, for example, an AC adapter 28 that converts an AC voltage into a DC voltage, and supplies power to the heater driving unit 21, the air pump 22, the solenoid valve 23, the display unit 25, the control unit 26, and the like. By the power supply circuit 27 supplying power to the heater driving unit 21, the air pump 22, the solenoid valve 23, the display unit 25, the control unit 26, and the like, the air massage device 1 becomes operable.

[0028] (2.2.2) Bag body The bag body 4 is worn on the user's leg 90. The drive system 2 includes at least two bag bodies 4 that are worn on the left and right legs 90 of the user respectively as the bag body 4. In the first embodiment, the drive system 2 includes a total of four bag bodies 4, two for each of the left and right legs 90 of the user.

[0029] As shown in FIG. 1, the bag body 4 is formed into a deformable cylindrical shape through which the user's leg 90 passes inside, and has openings 41 through which the leg 90 can enter and exit at both ends in the direction of entry and exit of the leg 90. In the first embodiment, the direction of entry and exit of the leg 90 is the direction in which the leg 90 lying on the floor extends, and is a direction along the horizontal direction. In the present disclosure, for convenience, the direction of entry and exit of the leg 90 is defined as the front-rear direction, and the upstream side in the direction of entry and exit is the side where the head of the user into which the leg 90 is inserted is located, and is the front side in the front-rear direction. Also, the user is assumed to be lying on the floor on their back, and the left and right as viewed from the user in this state are defined as the left and right in the present disclosure. The left-right direction is a direction orthogonal to the direction of entry and exit of the leg 90, and is a direction along the horizontal direction.

[0030] The bag body 4 has an airbag 3. In the first embodiment, the bag body 4 is constituted by the airbag 3, and the four bag bodies 4 are respectively constituted by the first airbag 3A to the fourth airbag 3D.

[0031] (2.2.3) Airbag The airbag 3 expands and contracts by supplying and exhausting air. More specifically, the airbag 3 expands by the air supplied by the air supply device 20. Also, the airbag 3 contracts when the air is sucked and exhausted by the air supply device 20. Alternatively, the airbag 3 contracts when the supply of air by the air supply device 20 is stopped and the airbag 3 is exhausted by its own elastic force or the compressive force applied to the airbag 3.

[0032] The airbag 3 is formed of, for example, polyamide alone or a resin having a two-layer structure of polyamide and polyurethane. The thickness of the airbag 3 is, for example, 0.5 mm. As such an airbag 3, a general airbag that has been conventionally used can be appropriately used.

[0033] In the first embodiment, the airbag 3 itself constitutes the bag body 4. That is, each airbag 3 serves as the bag body 4.

[0034] The first airbag 3A is attached to the front portion of the user's left lower leg 91, that is, the portion close to the thigh of the left lower leg 91. The front opening of the first airbag 3A constitutes the front opening 41 of the left bag body 4.

[0035] The second airbag 3B is attached to the rear portion of the user's left lower leg 91, that is, the portion close to the ankle of the left lower leg 91. The rear opening of the second airbag 3B constitutes the rear opening 41 of the left bag body 4.

[0036] The third airbag 3C is attached to the front portion of the user's right lower leg 91, that is, the portion close to the thigh of the right lower leg 91. The front opening of the third airbag 3C constitutes the front opening 41 of the right bag body 4.

[0037] The fourth airbag 3D is attached to the rear portion of the user's right lower leg 91, that is, the portion close to the ankle of the right lower leg 91. The rear opening of the fourth airbag 3D constitutes the rear opening 41 of the right bag body 4.

[0038] The first airbag 3A is disposed at a portion corresponding to the front portion of the user's left lower leg 91, the second airbag 3B is disposed at a portion corresponding to the rear portion of the user's left lower leg 91, and the rear portion of the first airbag 3A and the front portion of the second airbag 3B are overlapped. The first airbag 3A and the second airbag 3B are configured to overlap each other like a single bag body 4, but are not connected to each other.

[0039] The third airbag 3C is disposed at a portion corresponding to the front part of the right lower leg 91 of the user, the fourth airbag 3D is disposed at a portion corresponding to the rear part of the right lower leg 91 of the user, and the rear part of the third airbag 3C and the front part of the fourth airbag 3D are overlapped. The third airbag 3C and the fourth airbag 3D are configured to overlap each other to form a single bag body 4, but are not connected to each other.

[0040] As shown in FIGS. 3 and 4, the airbag 3 is connected to the air pump 22 via the air hose 29, the airbag nozzle 291, and the solenoid valve 23. As shown in FIG. 4, the first airbag 3A is connected to the first solenoid valve 23A via the first air hose 29A and the airbag nozzle 291A. The second airbag 3B is connected to the second solenoid valve 23B via the second air hose 29B and the airbag nozzle 291B. The third airbag 3C is connected to the third solenoid valve 23C via the third air hose 29C and the airbag nozzle 291C. The fourth airbag 3D is connected to the fourth solenoid valve 23D via the fourth air hose 29D and the airbag nozzle 291D.

[0041] (2.3) Housing, Base Portion As shown in FIGS. 4 to 7, the housing 11 is disposed at both end portions in the left - right direction of the main body portion 10. As portions constituting the housing 11, a first housing portion 11A to a fourth housing portion 11D are provided.

[0042] As shown in FIG. 7, the first housing portion 11A is disposed at the upper part of the left end portion of the main body portion 10, the second housing portion 11B is disposed at the lower part of the left end portion of the main body portion 10, and the first housing portion 11A and the second housing portion 11B are fixed to each other by a fixing tool 111 such as a screw. The left - hand housing 11 is constituted by the first housing portion 11A and the second housing portion 11B.

[0043] The third housing portion 11C is disposed at the upper part of the right end portion of the main body portion 10, the fourth housing portion 11D is disposed at the lower part of the right end portion of the main body portion 10, and the third housing portion 11C and the fourth housing portion 11D are fixed to each other by the fixing tool 111. The right - hand housing 11 is constituted by the third housing portion 11C and the fourth housing portion 11D.

[0044] The housing 11 is formed of a material having self-shaping properties, such as a resin including polypropylene. The thickness (length in the vertical direction) of the housing 11 is, for example, 45 mm.

[0045] As shown in FIGS. 4 and 5, an air supply device 20 is accommodated in the right housing 11. Nothing is particularly accommodated in the left housing 11. Thereby, the bulky air supply device 20 in the air massage device 1 is accommodated in the housing 11, facilitating miniaturization and thinning of the air massage device 1. Further, the sound emitted by the air supply device 20 (particularly the air pump 22) is less likely to leak outside the housing 11, achieving noise reduction of the air massage device 1. Furthermore, in the first embodiment, since the housing 11 is accommodated in the outer member 5, noise reduction of the air massage device 1 is further achieved.

[0046] As shown in FIGS. 4 to 7, a fixing plate 12 is disposed between the left and right housings 11. The fixing plate 12 has a rectangular shape in plan view and is formed of a material having self-shaping properties, such as a resin including polyethylene. The thickness of the fixing plate 12 is, for example, 1 mm. Holes 121 through which fixing tools 122 such as screws pass are formed at both ends of the fixing plate 12 in the left-right direction, and screw holes into which the fixing tools 122 are screwed are formed at portions corresponding to the holes 121 in the lower surface portions of the left and right housings 11.

[0047] The left end portion of the fixing plate 12 is disposed below the lower surface portion of the left housing 11, and the fixing tool 122 is passed through the hole 121 at the left end portion from below the fixing plate 12 and screwed into the screw hole in the lower surface portion of the left housing 11. Similarly, the right end portion of the fixing plate 12 is disposed below the lower surface portion of the right housing 11, and the fixing tool 122 is passed through the hole 121 at the right end portion from below the fixing plate 12 and screwed into the screw hole in the lower surface portion of the right housing 11. Thereby, the left and right housings 11 are respectively attached to the fixing plate 12, and the relative positions of the left and right housings 11 are held. The housing 11 and the fixing plate 12 constitute the base portion of the air massage device 1.

[0048] The fixed plate 12 is provided with a lower cushion 13. The lower cushion 13 is rectangular in plan view and is formed of a resin such as polyurethane, for example. The thickness of the lower cushion 13 is, for example, 10 mm. As the lower cushion 13, a front cushion 131, a rear cushion 132, a left cushion 133, and a right cushion 134 are provided.

[0049] The front cushion 131 is provided over substantially the entire length in the left - right direction at the front - end portion of the upper surface of the fixed plate 12. The rear cushion 132 is provided over substantially the entire length in the left - right direction at the rear - end portion of the upper surface of the fixed plate 12. The left cushion 133 is provided at the left - end portion of the upper surface of the fixed plate 12, between the cushion 131 and the cushion 132. The right cushion 134 is provided at the right - end portion of the upper surface of the fixed plate 12, between the cushion 131 and the cushion 132. The front cushion 131 to the right cushion 134 are attached to the fixed plate 12 by, for example, double - sided tape, but the method of attaching the front cushion 131 to the right cushion 134 to the fixed plate 12 is not limited.

[0050] Furthermore, a cushion 135 is provided at the central portion in the left - right direction on the upper surface of the front cushion 131, between the second airbag 3B and the fourth airbag 3D.

[0051] By providing the lower cushion 13, even when air is not supplied to the airbag 3, a buffering effect can be obtained between the floor and the leg portion 90 (particularly the lower leg portion 91) of the user when the leg portion 90 of the user is placed on the upper surface of the main body portion 10. Incidentally, the foot portion 92 of the user may be placed on the upper surface of the main body portion 10.

[0052] (2.4) Outer - shell member As shown in FIGS. 1 and 2, the outer member 5 is formed in a deformable bag shape so that the leg portion 90 can be inserted therein. The outer member 5 has an outer cloth 50 that constitutes the outer skin. The outer cloth 50 is formed in a tubular shape and has a leg insertion portion (leg insertion space) that penetrates in the front-rear direction inside. As shown in FIG. 1, the outer cloth 50 has an upper outer cloth 53 that constitutes the upper part (upper part of the outer member) of the outer member 5 and a lower outer cloth 54 that constitutes the lower part (lower part of the outer member) of the outer member 5. The outer cloth 50 (the upper outer cloth 53 and the lower outer cloth 54) is formed of fibers made of a resin such as polyester or nylon. The outer cloth 50 may be formed of a single piece of cloth, or the upper outer cloth 53 and the lower outer cloth 54 may be formed separately and then sewn together.

[0053] As shown in FIG. 2, the outer member 5 has an inlet 51 at the upstream end in the access direction, which can be opened and closed and through which the foot portion 92 and the lower leg portion 91 can enter and exit. Further, the outer member 5 has an outlet 52 at the downstream end in the access direction, which can be opened and closed and through which the foot portion 92 and the lower leg portion 91 can enter and exit.

[0054] When the leg portion 90 is not inserted, the outer member 5 is formed in a plate shape that extends along the access direction (front-rear direction) and the orthogonal direction (left-right direction) with the upper outer cloth 53 hanging down by its own weight and placed on the lower outer cloth 54. The outer member 5 is configured such that the inlet 51 is closed by the weight of the outer member 5 when the leg portion 90 is not inserted. When the inlet 51 of the outer member 5 is closed, the thickness (vertical length) of the air massage device 1 is approximately 45 mm, which is the same as the thickness of the housing 11.

[0055] The outer housing member 5 encloses at least the bag body 4 (airbag 3). As shown in FIGS. 8 to 9B, in the first embodiment, the outer housing member 5 encloses four bag bodies 4, a drive system 2 (including an air supply device 20), and a base portion. The outer housing member 5 houses the four bag bodies 4, the drive system 2, and the base portion in the internal leg insertion portions. By the outer housing member 5 enclosing the drive system 2, it is not necessary to provide the drive system 2 outside the outer housing member 5, and an air massage device 1 with an integrated and portable feeling can be obtained.

[0056] The upper outer cloth 53 is located above the four bag bodies 4 (airbags 3), the air supply device 20, and the base portion. The lower outer cloth 54 is located below the four bag bodies 4 (airbags 3), the air supply device 20, and the base portion.

[0057] The upper part of the outer housing member (upper outer cloth 53) is formed of a soft member and has a cushion 55 on which the leg portion 90 is placed. The cushion 55 has a rectangular shape in plan view and is formed of a resin such as polyurethane, for example. The thickness of the cushion 55 is, for example, 10 mm. The portion of the upper outer cloth 53 of the outer housing member 5 where the cushion 55 is provided becomes the placement portion on which the leg portion 90 is placed.

[0058] By providing the cushion 55, even when air is not supplied to the airbag 3, when the user's leg portion 90 (particularly the lower leg portion 91) is placed on the upper surface of the main body portion 10, the wide portion of the leg portion 90 is supported by the cushion 55 via the upper outer cloth 53, so that the force received by the leg portion 90 from the lower side (floor) via the air massage device 1 is easily dispersed.

[0059] (2.4.1) Attachment to the housing The air massage device 1 includes a housing 11 at both ends of the outer housing member 5 in the left - right direction. The outer housing member 5 is attached to both housings 11. That is, the left end portion of the outer housing member 5 is attached to the left - hand housing 11, and the right end portion of the outer housing member 5 is attached to the right - hand housing 11.

[0060] The attachment of the outer shell member 5 to the housing 11 is, for example, by means of a so-called planar fastener. One of the pair of planar fasteners that are detachably attached to each other is attached to the inner surface of the left end portion of the outer cloth 50, and the other of the pair of planar fasteners is attached to the outer surface of the left end portion of the left housing 11. Similarly, one of the pair of planar fasteners is attached to the inner surface of the right end portion of the outer cloth 50, and the other of the pair of planar fasteners is attached to the outer surface of the right end portion of the right housing 11.

[0061] At both the left and right end portions, the pair of planar fasteners are attached to each other, and the outer shell member 5 is attached to the housing 11. Thereby, the relative positional relationship among the outer shell member 5, the housing 11, and the base portion becomes difficult to change, and the outer shell member 5 becomes difficult to shift with respect to the housing 11 and the base portion.

[0062] (2.4.2) Attachment of the bag body As shown in FIG. 8, the bag body 4 is attached to the outer shell member 5. The bag body 4 has an attachment member 421 for attaching to the outer shell member 5. In the first embodiment, the attachment member 421 is a so-called planar fastener. The planar fastener is configured such that the attachment member 421 of the bag body 4 and the attachment member 561 of the outer shell member 5 form a pair.

[0063] In the first embodiment, the attachment member 421 is disposed at the central portion of the bag body 4 in the left - right direction. The attachment member 561, which is one of the pair of planar fasteners, is attached to the lower surface of the central portion in the left - right direction within the range corresponding to each airbag 3 (bag body 4) of the upper outer cloth 53, and the attachment member 421, which is the other of the pair of planar fasteners, is attached to the upper surface of the central portion in the left - right direction of each airbag 3 (bag body 4).

[0064] Also, as shown in FIG. 4, a mounting member 562 made of a pin is disposed at the center in the left-right direction within the range corresponding to each airbag 3 (bag body 4) on the lower surface of the fixing plate 12. The mounting member 562 holds the corresponding airbag nozzle 291 and airbag 3 through through-holes formed in the fixing plate 12, and sandwiches the fixing plate 12 between the mounting member 562, the airbag nozzle 291, and the airbag 3, thereby fixing each airbag 3 to the fixing plate 12. A protective seal 123 is attached to the portion of the lower surface of the fixing plate 12 corresponding to the mounting member 562.

[0065] The mounting member 561 and the mounting member 421 are formed at positions shifted from the cushion 55 in the horizontal direction so as not to interfere with the cushion 55. Note that openings or the like may be formed in the cushion 55 so that the mounting member 561 and the mounting member 421 do not interfere with the cushion 55.

[0066] By disposing the mounting member 42 at the center of the bag body 4 in the left-right direction, when the leg portion 90 is inserted into the bag body 4, the balance of the force applied to the bag body 4 in the left-right direction is good, the bag body 4 is difficult to move left and right, and it is suppressed that the bag body 4 moves left and right and detaches from the outer member 5.

[0067] Also, as described above, the bag body 4 is attached to the upper part of the outer member (upper outer cloth 53) and the lower part of the outer member (lower outer cloth 54), respectively. If the bag body 4 is attached to only one of the upper outer cloth 53 and the lower outer cloth 54, when the leg portion 90 is inserted into the bag body 4, the opposite side of the bag body 4 becomes easily movable around the portion attached to the outer cloth 50 of the bag body 4 due to the force applied to the bag body 4. For this reason, when the bag body 4 moves, the bag body 4 is likely to detach from the outer member 5. On the other hand, by attaching the bag body 4 to both the upper outer cloth 53 and the lower outer cloth 54, when the leg portion 90 is inserted into the bag body 4, the bag body 4 is difficult to move, and it is suppressed that the bag body 4 moves and detaches from the outer member 5.

[0068] (2.4.3) Summary of Outer Member As shown in FIG. 8, since the outer member 5 houses the base portion in the internal leg insertion portion and the outer member 5 is attached to the housing 11, the overall shape of the outer member 5 and the air massage device 1 is maintained.

[0069] As shown in FIG. 2, in a state where the leg portion 90 is not inserted into the outer member 5, the inlet 51 is configured to be closed by the weight of the outer member 5. Thereby, when the air massage device 1 is stored or when the airbag 3 is not in use, that is, when the main body portion 10 is not performing massage, the air massage device 1 can be made smaller and thinner. For this reason, the storage space of the air massage device 1 does not increase. Further, even if it is left on the bed, it does not get in the way, and the user can sleep with the lower leg portion 91 or the foot portion 92 placed on the air massage device 1.

[0070] Also, when performing massage by the airbag 3, the user can insert the foot portion 92 from the inlet 51 of the outer member 5 while lying horizontally on the floor, and insert the lower leg portion 91 rearward while widening the inlet 51 and the leg insertion space. Thereby, the user can insert the lower leg portion 91 into the outer member 5 without using hands from a state where the inlet 51 of the outer member 5 is closed while lying horizontally on the floor, and receive massage of the lower leg portion 91 by the airbag 3.

[0071] Further, since the outer member 5 has the cushion 55, it is possible to construct a more effective usage form in which the user uses it as a placement portion without inserting the leg portion 90 (particularly the lower leg portion 91) into the air massage device 1. That is, if the cushion 55 is not provided in the air massage device 1, even if the user places the leg portion 90 on the air massage device 1, the force received by the leg portion 90 from below is not dispersed, and the comfort of the leg portion 90 may be poor. On the other hand, by providing the cushion 55 in the air massage device 1, the comfort of the leg portion 90 when the user places the leg portion 90 on the air massage device 1 is improved, so that more active use as a placement portion for the lower leg portion 91 or the foot portion 92 becomes possible.

[0072] (2.5) Foot Cover As shown in FIGS. 1, 10A, and 10B, the foot cover 7 covers the user's foot portion 92. The foot cover 7 is formed in a deformable bag shape. The foot cover 7 has an outer cloth that constitutes the outer skin. The outer cloth has a foot insertion portion (foot insertion space) inside. The outer cloth has an upper outer cloth 73 that constitutes the upper part of the foot cover 7 and a lower outer cloth 74 that constitutes the lower part of the foot cover 7. The outer cloth is formed of fibers made of a resin such as polyester or nylon, for example. The outer cloth may be formed of a single piece of cloth, or the upper outer cloth 73 and the lower outer cloth 74 may be formed separately and then sewn together.

[0073] The foot cover 7 has a cover entrance 71 through which the foot portion 92 can enter and exit at the upstream end (front end) in the entry and exit direction. The foot cover 7 has a closing portion 72 at the downstream end (rear end) in the entry and exit direction to prevent the foot portion 92 from exiting the foot cover 7. The closing portion 72 is constituted by a folded-back portion where the outer cloth is folded back to form the boundary between the upper outer cloth 73 and the lower outer cloth 74. In the first embodiment, the foot cover 7 has only the cover entrance 71 as an opening.

[0074] The upstream end (front end) of the foot cover 7 in the entry and exit direction is attached to the downstream end (rear end) of the outer contour member 5 in the entry and exit direction. Specifically, the rear end of the upper outer cloth 53 of the outer contour member 5 and the front end of the upper outer cloth 73 of the foot cover 7 are sewn together to form a connecting portion 75 (sewn portion). Note that the rear end of the lower outer cloth 54 of the outer contour member 5 and the front end of the lower outer cloth 74 of the foot cover 7 are not sewn together, and an opening is formed.

[0075] The foot cover 7 is formed such that the length from the blocking portion 72 to the upstream end (or the connecting portion 75) in the access direction is the standard foot length. The standard foot length is the length of the foot of an average adult in Japan (from the toe to the ankle). By forming the length from the blocking portion 72 of the foot cover 7 to the cover inlet 71 (or the connecting portion 75) to be the standard foot length, the entire foot 92 can be easily accommodated within the foot cover 7. Also, when the foot 92 is inserted and the toe hits the blocking portion 72 to stop the movement of the foot 92, the foot 92 is accommodated within the foot cover 7 and the position of the ankle is located at the outlet 52 of the outer member 5.

[0076] Moreover, since an opening is formed between the rear end portion of the lower outer cloth 54 and the front end portion of the lower outer cloth 74, it becomes easier to accommodate the foot 92 within the foot cover 7 even if the size of the foot 92 is different. For example, as shown in FIG. 10A, in the case of a user with a small-sized foot 92, while extending the direction in which the foot 92 extends relatively close to horizontal, the position of the ankle is located at the outlet 52 of the outer member 5, and the foot 92 can be accommodated within the foot cover 7. Also, as shown in FIG. 10B, in the case of a user with a large-sized foot 92, if the direction in which the foot 92 extends is directed upward, although the heel portion is difficult to be accommodated within the foot cover 7, the position of the ankle is located at the outlet 52 of the outer member 5, and the foot 92 can be accommodated within the foot cover 7.

[0077] (2.5.1) Heater A heater 76 is provided in the foot cover 7. As the heater 76, a first heater 76A corresponding to the left leg portion 90 of the user and a second heater 76B corresponding to the right leg portion 90 are provided. The heater 76 is disposed at a position separated from the closing portion 72 of the lower outer cloth 74 of the foot cover 7 by a first predetermined distance L1 on the upstream side (front side) in the entering and exiting direction. That is, the heater 76 is to be disposed at a predetermined position of the foot portion 92 with the closing portion 72 where the toe of the foot portion 92 is located as a reference (starting point). Thereby, it becomes easier to dispose the heater 76 at a predetermined position of the foot portion 92. In the first embodiment, the predetermined position of the foot portion 92 is the back of the foot portion 92 and the base portion of the finger. The first predetermined distance L1 can take any value including 0, can be set as appropriate, and is not particularly limited.

[0078] (2.5.2) Positional relationship with the airbag based on the ankle The airbag 3 is disposed at a position separated from the outlet 52 of the outer member 5 by a second predetermined distance L2 on the upstream side (front side) in the entering and exiting direction. That is, in the outer member 5, the airbag 3 is to be disposed at a predetermined position of the lower leg portion 91 with the outlet 52 where the user's ankle is located as a reference (starting point). Thereby, it becomes easier to dispose the airbag 3 at a predetermined position of the lower leg portion 91. In the first embodiment, it is assumed that the first airbag 3A and the third airbag 3C are applied to the portion of the lower leg portion 91 of the user close to the thigh, and the second airbag 3B and the fourth airbag 3D are applied to the portion of the lower leg portion 91 of the user close to the ankle. For this reason, it becomes easier to align each airbag 3 at a predetermined position of the lower leg portion 91 with the user's ankle located at the outlet 52 of the outer member 5 as a reference. The second predetermined distance L2 can take any value including 0, can be set as appropriate, and is not particularly limited.

[0079] (2.5.3) Summary of the foot cover By setting the length from the closing portion 72 to the front end portion of the foot cover 7 as the foot standard length, it becomes easier for the foot portion 92 to be accommodated in the foot cover 7. Also, in a state where the toe hits the closing portion 72, it becomes easier to position the ankle at the outlet 52 of the outer member 5.

[0080] In addition, since the heater 76 is disposed at a position separated from the closing portion 72 of the foot cover 7 by a first predetermined distance L1 toward the front side, it becomes easier to dispose the heater 76 at a predetermined position of the foot portion 92. That is, as described above, by disposing the heater 76 at a portion of the foot cover 7 corresponding to the predetermined position of the foot portion 92 with reference to the closing portion 72 where the tip of the toe of the foot portion 92 is located, it becomes easier to apply the heater 76 to the predetermined position of the foot portion 92.

[0081] (3) Second Embodiment Hereinafter, the air massage device 1 according to the second embodiment will be described with reference to FIGS. 11A to 11C. Note that since the air massage device 1 according to the second embodiment is mostly the same as the air massage device 1 according to the first embodiment, redundant descriptions will be omitted.

[0082] In the first embodiment, the length from the closing portion 72 to the front end portion of the foot cover 7 could not be changed. In contrast, in the second embodiment, the length from the closing portion 72 to the front end portion of the foot cover 7 can be adjusted.

[0083] The air massage device 1 further includes a foot cover length adjusting portion 77 that adjusts the length from the closing portion 72 to the upstream end portion (front end portion) in the entry / exit direction. The foot cover length adjusting portion 77 is constituted by a so-called fastener and a spare portion mainly composed of a part (mainly the front side portion) of the upper outer cloth 73 of the foot cover 7. Near the rear end portion of the upper outer cloth 53 of the outer housing member 5, one of the connecting members forming a pair of fasteners is sewn, and the other of the connecting members is sewn to the front portion of the upper outer cloth 73 of the foot cover 7.

[0084] When shortening the length from the closing portion 72 to the front end portion of the foot cover 7, as shown in FIG. 11A, the connecting members forming a pair of fasteners are connected to each other. As a result, the spare portion of the upper outer cloth 73 is in a folded state, and the length of the foot cover 7 becomes a length that does not include the length of the spare portion.

[0085] On the other hand, when increasing the length from the closing portion 72 to the front end portion of the foot cover 7, as shown in FIGS. 11B and 11C, the connecting members forming a pair of fasteners are not connected to each other. As a result, the spare portion of the upper outer cloth 73 is not folded, and the length of the foot cover 7 becomes the length including the length of the spare portion.

[0086] As a result, even when the sizes of the user's feet 92 are significantly different, the entire feet 92 can be easily accommodated in the foot cover 7.

[0087] Note that the foot cover length adjustment portion 77 of the second embodiment is applicable not only to the air massage device 1 of the first embodiment but also to the air massage devices 1 of the third to fifth embodiments described later.

[0088] (4) Third Embodiment Hereinafter, the air massage device 1 according to the third embodiment will be described with reference to FIGS. 12A to 13B. Note that since the air massage device 1 according to the third embodiment is mostly the same as the air massage device 1 according to the first embodiment, redundant explanations will be omitted.

[0089] In the first embodiment, the outer member 5 is not particularly provided with a storage portion for the foot cover 7. On the other hand, in the third embodiment, a storage portion 57 for the foot cover 7 is provided in the outer cloth 50 of the outer member 5.

[0090] FIGS. 12A and 12B show an example in which a storage portion 57 for the foot cover 7 is provided on the upper surface of the upper portion of the outer member (upper outer cloth 53) of the outer member 5. The storage portion 57 is a pocket formed by a cloth provided outside the upper outer cloth 53. The material of the cloth constituting the storage portion 57 is the same as that of the upper outer cloth 53. The cloth constituting the storage portion 57 is sewn to the upper outer cloth 53, and the space between the cloth and the upper outer cloth 53 is open rearward. As a result, the foot cover 7 can be folded upward around the connecting portion 75 and stored in the storage portion 57.

[0091] Figures 13A and 13B show an example in which a storage portion 57 for the foot cover 7 is provided on the lower surface of the lower part of the outer shell member 5 (lower outer cloth 54) of the outer shell member 5. The storage portion 57 is a pocket formed by a cloth provided outside the lower outer cloth 54. The material of the cloth constituting the storage portion 57 is the same as that of the lower outer cloth 54. The cloth constituting the storage portion 57 is sewn to the lower outer cloth 54, and the space between the cloth and the lower outer cloth 54 is open toward the rear. Thereby, the foot cover 7 can be folded downward about the connecting portion 75 and the foot cover 7 can be stored in the storage portion 57.

[0092] Note that the storage portion 57 of the third embodiment is applicable not only to the air massage device 1 of the first embodiment but also to the air massage devices 1 of the second embodiment, the fourth embodiment, and the fifth embodiment described later.

[0093] (5) Fourth Embodiment Hereinafter, the air massage device 1 according to the fourth embodiment will be described with reference to FIGS. 14A and 14B. Note that since the air massage device 1 according to the fourth embodiment is mostly the same as the air massage device 1 according to the first embodiment, redundant descriptions will be omitted.

[0094] In the fourth embodiment, a pressing member 78 for pressing the foot portion 92 inserted into the foot cover 7 against the heater 76 is further disposed at a position separated from the upstream side in the entry / exit direction from the closing portion 72 of the foot cover 7 by a first predetermined distance.

[0095] FIG. 14A shows an example of the positional relationship in which the heater 76 is sandwiched between the pressing member 78 and the foot portion 92 inserted into the foot cover 7. The heater 76 is disposed on the lower outer cloth 74, and the pressing member 78 is disposed on the upper outer cloth 73. The pressing member 78 is formed of a resin such as polyurethane, for example. Thereby, the pressing member 78, the foot portion 92, and the heater 76 are in a state of being clamped by the foot cover 7 inside the foot cover 7, and the adhesion between the foot portion 92 and the heater 76 is improved.

[0096] Fig. 14B shows an example of the positional relationship in which the pressing member 78 and the heater 76 sandwich the foot portion 92 inserted into the foot cover 7. The heater 76 is disposed on the lower outer cloth 74, and the pressing member 78 is disposed on the lower outer cloth 74 so as to overlap the heater 76 from the outside of the heater 76. As a result, the pressing member 78, the heater 76, and the foot portion 92 are clamped by the foot cover 7 in the foot cover 7, and the adhesion between the foot portion 92 and the heater 76 is improved.

[0097] Note that the pressing member 78 of the fourth embodiment is applicable not only to the air massage device 1 of the first embodiment but also to the air massage devices 1 of the third embodiment, the fourth embodiment, and the fifth embodiment described later.

[0098] (6) Fifth Embodiment Hereinafter, the air massage device 1 according to the fifth embodiment will be described with reference to FIGS. 15 to 17. Note that since the air massage device 1 according to the fifth embodiment is mostly the same as the air massage device 1 according to the first embodiment, redundant descriptions will be omitted.

[0099] In the fifth embodiment, as the airbag 3, a first airbag 3A attached to the front part of the left lower leg 91 of the user, a second airbag 3B attached to the rear part of the left lower leg 91, a third airbag 3C attached to the front part of the right lower leg 91, and a fourth airbag 3D attached to the rear part of the right lower leg 91 are provided. Further, the first airbag 3A to the fourth airbag 3D constitute the bag body 4, and these points are the same as those of other embodiments.

[0100] Since the first airbag 3A and the third airbag 3C, and the second airbag 3B and the fourth airbag 3D are formed to be symmetrical with each other, the first airbag 3A will be described as the airbag 3 attached to the front part of the lower leg 91, and the second airbag 3B will be described as the airbag 3 attached to the rear part of the lower leg 91. FIG. 15 shows a developed view of the entire left airbag 3, FIG. 16 shows a developed view of the first airbag 3A, and FIG. 17 shows a developed view of the second airbag 3B.

[0101] As shown in FIG. 15, the airbag 3 applied to the left leg portion 90 is composed of a first airbag 3A and a second airbag 3B. The first airbag 3A and the second airbag 3B are formed separately and attached to each other by sewing, welding, adhesion, or the like to be integrated. In this way, by being divided into a plurality of airbags 3 (3A, 3B), it becomes easy to finely correspond to each portion applied to the lower leg portion 91.

[0102] As shown in FIG. 16, the first airbag 3A is formed from a single sheet having one air chamber 31A inside. By rolling up this sheet so as to surround the periphery of the leg portion 90, it is in a state of being inserted into the outer member 5.

[0103] As shown in FIG. 17, the second airbag 3B is formed from a single sheet having one air chamber 31B inside. By rolling up this sheet so as to surround the periphery of the leg portion 90, it is in a state of being inserted into the outer member 5.

[0104] The area of the air chamber 31A of the first airbag 3A shown in FIG. 16 is larger than the area of the air chamber 31B of the second airbag 3B shown in FIG. 17.

[0105] As shown in FIG. 15, the rear portion of the first airbag 3A and the front portion of the second airbag 3B are overlapped. More specifically, the front end portion of the first airbag 3A and the rear end portion of the second airbag 3B are not overlapped, and the other portions are overlapped. In this way, by overlapping the first airbag 3A and the second airbag 3B with a shift in the front-rear direction, the airbag 3 is arranged over a long portion in the front-rear direction of the outer member 5 (preferably the entire length inserted into the outer member 5).

[0106] Also, the first airbag 3A and the second airbag 3B are overlapped so that the first airbag 3A is on the inner side, that is, the first airbag 3A is in contact with the lower leg portion 91 on the inner side and in contact with the second airbag 3B on the outer side.

[0107] As shown in FIG. 16, in the first airbag 3A, recessed portions 321 and 322 that are recessed rearward are formed at two locations in the front part of the air chamber 31A. In the first airbag 3A, a recessed portion 323 that is recessed forward is formed at one location in the rear part of the air chamber 31A. As a result, when the first airbag 3A expands, a broken line 331 is formed along the recessed portion 321 and the recessed portion 323, a broken line 332 is formed along the recessed portion 322 and the recessed portion 323, and the air chamber 31A is substantially divided into three by the broken line 331 and the broken line 332.

[0108] Also, in each of the three divided parts of the air chamber 31A, top portions 341 to 343 that bulge the most and become highest when inflated are formed.

[0109] As shown in FIG. 17, in the second airbag 3B, a recessed portion 324 that is recessed rearward is formed at one location in the front part of the air chamber 31B. As a result, when the second airbag 3B expands, a broken line 333 that extends in the front-rear direction is formed through the recessed portion 324, and the air chamber 31B is substantially divided into two by the broken line 333.

[0110] Also, in each of the two divided parts of the air chamber 31B, top portions 344 to 345 that bulge the most and become highest when inflated are formed.

[0111] As shown in FIG. 15, in the airbag 3 in which the first airbag 3A and the second airbag 3B are combined, each of the top portions 341 to 345 can press a predetermined part of the lower leg 91 to perform a delicate massage for each part.

[0112] Note that the airbag 3 of the fifth embodiment is applicable not only to the air massage device 1 of the first embodiment but also to the second to fourth embodiments.

[0113] (7) Modification Hereinafter, modifications of the above embodiments will be listed. The modifications described below can be applied in appropriate combinations.

[0114] The air massage device 1 of the present disclosure may be used with the user lying face down on the floor with the legs 90 extended horizontally, or it is not necessarily used with the user lying on the floor with the legs 90 extended horizontally.

[0115] The standard length of the foot does not have to be the exact average value of the foot length of the average adult in Japan. For example, it may be any value between the value obtained by adding the standard deviation of the foot length to the average value of the foot length of adults in Japan and the value obtained by subtracting it.

[0116] The AC adapter 28 may be included in the air supply device 20, or may not be included in the air supply device 20 (air massage device 1).

[0117] The shape, size, material, thickness, etc. of the airbag 3 are not limited.

[0118] The bag body 4 may be attached to a part of the user's leg 90 other than the lower leg 91. For example, the bag body 4 may be attached to the entire leg 90 of the user. The bag body 4 is attached to at least a part of the user's leg 90, but is preferably attached to the lower leg 91 in particular.

[0119] The number of bag bodies 4 provided in the drive system 2 is not particularly limited. A total of two bag bodies 4 may be provided, one each for the left and right legs 90 of the user, or three or more bag bodies 4 may be provided for each of the left and right legs 90, or the number of bag bodies 4 provided for each of the left and right legs 90 may be different. Also, the drive system 2 may include only one bag body 4.

[0120] The bag body 4 does not have to be constituted by the airbag 3. That is, for example, the bag body 4 may have an outer cloth and an inner cloth separately from the airbag 3 and have the airbag 3 between the outer cloth and the inner cloth. Also, one bag body 4 may have a plurality of airbags 3, or not all bag bodies 4 have to have airbags 3. At least one bag body 4 may have an airbag 3. The number of airbags 3 provided in the bag body 4 is not limited.

[0121] The first airbag 3A and the second airbag 3B may be sewn or otherwise connected to each other. The third airbag 3C and the fourth airbag 3D may be sewn or otherwise connected to each other.

[0122] The shape, size, material, etc. of the housing 11 are not limited. The thickness of the housing 11 is preferably 40 mm or more and 50 mm or less. Since it is necessary to accommodate the air supply device 20 in the housing 11, the lower limit of the thickness of the housing 11 is approximately 40 mm, but it is not particularly limited. Also, from the perspective of ease of housing the air massage device 1, the upper limit of the thickness of the housing 11 is preferably as small as possible, but it may be 50 mm or more and is not particularly limited.

[0123] The housing 11 does not have to be provided at both ends of the outer member 5 and may be provided only at one end. Also, the housing 11 is an arbitrary member and does not have to be provided on the main body 10.

[0124] The air supply device 20 may be housed in the left housing 11 instead of the right housing 11.

[0125] The shape, size, thickness, material, etc. of the fixing plate 12 are not limited. The fixing plate 12 is an arbitrary member and does not have to be provided on the main body 10.

[0126] The shape, size, thickness, material, etc. of the lower cushion 13 are not limited.

[0127] The shape, size, thickness, material, etc. of the outer cloth 50 of the outer member 5 and the outer cloth of the foot cover 7 are not limited. The outer cloth 50 is preferably formed of a soft member such as the cloth constituting general clothing.

[0128] That the entrance 51 is closed by the self-weight of the outer member 5 does not mean that the entrance 51 is completely closed by the self-weight of the outer member 5, but means a state in which the leg portion 90 (particularly the entire foot portion 92) cannot be inserted into the entrance 51 without the entrance 51 widening.

[0129] The shape, size, thickness, material, etc. of the cushion 55 are not limited.

[0130] The housing 11 does not have to be housed in the leg insertion portion inside the outer member 5. That is, the housing 11 may be located outside the outer member 5.

[0131] The attachment of the outer member 5 to the housing 11 does not have to be by a planar fastener. For example, the outer member 5 may be attached to the housing 11 with an adhesive. Also, the outer member 5 does not have to be attached to both housings 11 and may be attached to only one of the housings 11. Further, the outer member 5 does not necessarily have to be attached to the housing 11.

[0132] The attachment member 42 does not have to be disposed at the center of the bag body 4 in the left - right direction, and the attachment member 56 does not have to be disposed at the center of the range corresponding to each bag body 4 of the outer cloth 50 in the left - right direction. Also, the attachment member 42 and the attachment member 56 do not necessarily have to be provided.

[0133] The bag body 4 does not have to be attached to both the upper part of the outer member (upper outer cloth 53) and the lower part of the outer member (lower outer cloth 54). That is, the bag body 4 may be attached to only one of the upper outer cloth 53 and the lower outer cloth 54, or may not be attached to either the upper outer cloth 53 or the lower outer cloth 54.

[0134] Other means than planar fasteners may be used for the attachment of the outer member 5 to the housing 11 and for the attachment of the bag body 4 to the outer member 5. For example, one end of a string may be fixed to the outer member 5 and the housing 11 respectively, and the other ends of these strings may be tied together so that the outer member 5 is attached to the housing 11, and the same applies to the attachment of the bag body 4 to the outer member 5.

[0135] The predetermined position of the foot portion 92 does not have to be the base portion of the finger on the back of the foot portion 92 and can be set at any part.

[0136] The foot cover length adjustment part 77 is not limited to the one using a fastener. For example, as the foot cover length adjustment part 77, a so-called snap pin may be used instead of the fastener.

[0137] The foot cover 7 has an arbitrary configuration in the present disclosure and may not be provided in the air massage device 1.

[0138] (8) Summary As described above, the air massage device (1) of the first aspect includes a drive system (2) and an outer member (5). The drive system (2) includes an air supply device (20) and two bag bodies (4). The air supply device (20) supplies air to the airbag (3). The two bag bodies (4) have an airbag (3) that expands and contracts by air supply and exhaust. The two bag bodies (4) have openings (41) at both ends in the access direction of the user's leg (90) through which the leg (90) can enter and exit. The outer member (5) is formed in a deformable bag shape and encloses the bag body (4). The outer member (5) has an entrance (51) at the upstream end in the access direction that can be opened and closed and through which the leg (90) can enter and exit. The outer member (5) is configured such that the entrance (51) closes due to the self-weight of the outer member (5) when the leg (90) is not inserted.

[0139] In the first aspect, miniaturization and thinning of the air massage device (1) are achieved when the airbag (3) is not in use, such as when the air massage device (1) is stored.

[0140] The second aspect can be realized by combining with the first aspect. In the second aspect, the outer member (5) encloses the air supply device (20).

[0141] In the second aspect, the drive system (2) does not have to be provided outside the outer member (5), and an air massage device (1) with a sense of unity and integrity can be obtained.

[0142] The third aspect can be realized by combination with the first or second aspect. In the third aspect, the bag body (4) has an attachment member (42) for attachment to the outer member (5). The attachment member (42) is disposed at the center of the bag body (4) in the direction orthogonal to the access direction.

[0143] In the third aspect, since the attachment member (42) is disposed at the center of the bag body (4) in the left - right direction, when the leg part (90) is inserted into the bag body (4), the balance of the force applied to the bag body (4) in the left - right direction is good, the bag body (4) is less likely to move left and right, and it is suppressed that the bag body (4) moves left and right and detaches from the outer member (5).

[0144] The fourth aspect can be realized by combination with the third aspect. In the fourth aspect, the access direction and the orthogonal direction are directions along the horizontal direction. The outer member (5) is formed in a plate shape extending along the access direction and the orthogonal direction. The outer member (5) has an upper outer member part (upper outer cloth 53) and a lower outer member part (lower outer cloth 54). The upper outer member part (upper outer cloth 53) is located above the bag body (4). The lower outer member part (lower outer cloth 54) is located below the bag body (4). The bag body (4) is attached to the upper outer member part (upper outer cloth 53) and the lower outer member part (lower outer cloth 54) respectively.

[0145] In the fourth aspect, when the leg part (90) is inserted into the bag body (4), the bag body (4) is less likely to move, and it is suppressed that the bag body (4) moves and detaches from the outer member (5).

[0146] The fifth aspect can be realized by combination with any one of the first to fourth aspects. In the fifth aspect, a housing (11) is provided at the end of the outer member (5) in the direction orthogonal to the access direction. The outer member (5) is attached to the housing (11).

[0147] In the fifth aspect, the relative positional relationship between the outer member (5) and the housing (11) is less likely to change, and the outer member (5) is less likely to shift with respect to the housing (11).

[0148] The sixth aspect can be realized in combination with the fifth aspect. In the sixth aspect, an air supply device (20) is housed in the housing (11).

[0149] In the sixth aspect, the bulky air supply device (20) among the air massage devices (1) is housed in the housing (11), facilitating the miniaturization and thinning of the air massage device (1). Also, it becomes easier to achieve quiet operation of the air massage device (1).

[0150] The seventh aspect can be realized in combination with the fifth or sixth aspect. In the seventh aspect, the housings (11) are provided at both ends of the outer member (5) in the orthogonal direction. The outer member (5) is attached to both housings (11). The outer member (5) has an upper outer member (upper outer cloth 53) and a lower outer member (lower outer cloth 54). The upper outer member (upper outer cloth 53) is located above the bag body (4). The lower outer member (lower outer cloth 54) is located below the bag body (4). The upper outer member (upper outer cloth 53) is formed of a soft member and has a cushion (55) on which the leg portion (90) is placed.

[0151] In the seventh aspect, since the outer member (5) is attached to both housings (11), the shape of the easily deformable outer member (5) is less likely to be disturbed, and it is easy to maintain the shape of the outer member (5). Also, when the user's leg portion (90) is placed on the upper surface of the air massage device (1), the wide portion of the leg portion (90) is supported by the cushion (55) via the upper outer cloth (53), making it easier to disperse the force received by the leg portion (90) from the floor through the air massage device (1).
