Detailed Embodiment

[0017] [Overall Structure of the Massage Machine] Hereinafter, the overall structure of the massage machine 1 according to an embodiment of the present invention will be described. Figure 1 This is a perspective view of the massage machine 1 according to an embodiment of the present invention. As Figure 1 shown, the massage machine 1 according to an embodiment of the present invention is composed of a seat part 3 on which the user sits, a backrest part 4 provided at the rear of the seat part 3 for the user to lean on, a footrest part 5 provided at the front of the seat part 3, an armrest part 2 installed on the side part of the seat part 3, and armrest part units 6L and 6R installed on the upper surface of the armrest part 2. The seat part 3, the backrest part 4, the footrest part 5, and the armrest part 2 (including the armrest part units 6L and 6R) have the function of a body support part S.

[0018] Figure 2 This is a block diagram of the massage machine 1 according to an embodiment of the present invention. As Figure 1 、 Figure 2 shown, the massage machine 1 has a massage part M (massage mechanism 99, hip massage part 3a, back massage part 4a, foot massage part 5a, arm massage part 6a) for massaging the user, a control part 7 for controlling the functions of the massage machine 1, a controller 8 for performing various operations of the massage machine 1, an air supply and exhaust device 9 for supplying air to or discharging air from the airbag 100, and a drive part (not shown) for raising or lowering the footrest part 5. Each structure will be described later.

[0019] The hip massage part 3a, the back massage part 4a, the foot massage part 5a, and the arm massage part 6a are airbags for the massage machine (airbag 100). The airbag for the massage machine (airbag 100) is an airbag that expands and contracts by the supply and discharge of air. The airbag for the massage machine (airbag 100) is configured to be connectable to a piping 60 for supplying air. The piping 60 is integrally formed on the body support part S. By integrally forming the piping 60 on the body support part S, the amount of piping 60 used in the airbag for the massage machine (airbag 100) can be reduced. The detailed content will be described later.

[0020] Further, although not shown, an extrusion airbag may also be provided on the massage mechanism 99. The extrusion airbag is an airbag 100 that expands and contracts by supplying and discharging air. The extrusion airbag (airbag 100) is configured to be connectable to a pipe for supplying air. The pipe is integrally formed with the body support portion S. By integrally forming the pipe with the body support portion S, the pipe used in the extrusion airbag (airbag 100) provided on the massage mechanism 99 can be reduced.

[0021] [Structure of the backrest] Figure 3 FIG. is a view showing the body support portion S (backrest 4) according to an embodiment of the present invention, Figure 3 (a) is a view of a cross-section cut along the vertical direction as observed from the left side, Figure 3 (b) is a view of a cross-section cut along the vertical direction as observed from the left side, Figure 3 (c) is a view of a cross-section obtained by cutting the backrest 4 in the state of Figure 3 (b) along the left-right direction as observed from the plane. More specifically, Figure 3 (a) is a cross-sectional view showing a state in which the pipe 60 is integrally formed inside the body support portion S (backrest 4), Figure 3 (b) and (c) are cross-sectional views showing a state in which the pipe 60 is integrally formed on the back surface of the body support portion S (backrest 4).

[0022] As Figures 1 to 3 shown, the backrest 4 is composed of a rectangular member that is longitudinally long in the vertical direction. The backrest 4 functions as the body support portion S that supports the upper body of the user. A guide rail 16 (refer to Figure 1 ) is provided inside the backrest 4, and a massage mechanism 99 (massage portion M) is provided via the guide rail 16. By moving the massage mechanism 99 up and down along the guide rail 16, the upper body of the user can be massaged. Further, the front surface of the backrest 4 is covered with a cover member (not shown). That is, the massage mechanism 99 can massage the upper body (the back of the body such as the shoulders and waist) of the user sitting on the seat portion 3 via the cover member (not shown).

[0023] The backrest 4 is preferably composed of a rigid member such as a synthetic resin having a predetermined strength. By being composed of a rigid member, the load of the user can be received by the backrest 4. Further, by forming holes that serve as air passages in the rigid member such as a synthetic resin, the holes themselves can be used as the pipe 60, and the pipe 60 can be integrally formed with the backrest 4 (body support portion S). Accordingly, it is possible to reduce the piping 60 used in the backrest 4 of the massage machine 1 (for example, shorten the length of the air pipe for supplying air to the airbag 100). In addition, a cushioning member such as urethane can be installed on the front surface of the backrest 4 (the surface that abuts against the back of the user's upper body) to improve the comfort when the user leans on the backrest 4.

[0024] On the left and right sides of the backrest 4, there are provided back massage parts 4a (massage parts M) for massaging the upper body of the user leaning on the backrest 4. More specifically, a pair of left and right (refer to Figure 1 ) are provided near the center in the vertical direction on the left and right sides of the backrest 4. The back massage part 4a is composed of an airbag 100 that expands and contracts by the supply and discharge of air.

[0025] As Figure 3 shown, a recess 4c for installing the back massage part 4a is formed on the front surface of the backrest 4. The outer periphery of the recess 4c is slightly larger than the outer periphery of the back massage part 4a. The depth of the recess 4c is such that when the back massage part 4a is installed, the front surface of the backrest 4 and the front surface of the back massage part 4a become substantially the same plane. Accordingly, when the back massage part 4a is installed in the recess 4c, it is possible to make the front surface of the backrest 4 and the front surface of the back massage part 4a substantially the same plane, and when the user leans on the backrest 4, it is possible to reduce the discomfort caused by the back massage part 4a abutting against the user.

[0026] In addition, the back massage part 4a is preferably configured to be able to expand and contract independently on the left and right. And the structure of the massage part M disposed on the backrest 4 is an example and is not limited thereto. For example, it can be disposed near the user's waist or near the user's shoulder. And multiple can be appropriately combined and disposed respectively, and the number of the back massage parts 4a disposed is not limited either. As long as it can massage the upper body of the user.

[0027] A connecting part 61 for connecting the back massage part 4a and the piping 60 is provided at the center of the recess 4c. More specifically, a connecting part 61b (61) is provided at the front end of the piping 60 (the hole provided in the backrest 4) provided in the backrest 4. By directly installing the connecting part 61b (61) at the front end of the piping 60 (the side facing the airbag 100) provided in the backrest 4, it is possible to easily attach and detach the back massage part 4a to and from the backrest 4. The connecting part 61b (61) will be described later. In addition, in the present embodiment, the case where the back massage unit 4a is installed in the concave portion 4c provided in the backrest 4 has been described, but this is merely an example and is not limited thereto. For example, it may be configured such that the concave portion 4c is not provided, and the back massage unit 4a is directly installed on the backrest 4.

[0028] A state in which the pipe 60 is integrally formed inside the backrest 4 (body support portion S) will be described. In addition, if the pipe 60 can be integrally formed on the backrest 4 (body support portion S), it can be formed by any method. As an example, a case where it is formed by a method of opening a hole in the backrest 4 will be described.

[0029] As Figure 3 (a) shows, the back massage unit 4a (massage unit M) provided on the backrest 4 is connected to the air supply and exhaust device 9 via the pipe 60. More specifically, the pipe 60 is composed of a first pipe 60a connected to the air supply and exhaust device 9 and a pipe (hole provided in the backrest 4) integrally formed inside the backrest 4 and connected to the airbag 100, i.e., a second pipe 60b. The second pipe 60b and the first pipe 60a are connected via a connecting portion 61 (refer to Figure 11 ). The first pipe 60a and the second pipe 60b will be described later.

[0030] The back massage unit 4a is connected to the second pipe 60b via a connecting portion 61b (61). That is, the air supply and exhaust device 9 is connected to the first pipe 60a, the first pipe 60a and the second pipe 60b are connected via the connecting portion 61, and the second pipe 60b and the back massage unit 4a are connected via the connecting portion 61. The air discharged from the air supply and exhaust device 9 passes through the respective pipes 60a and 60b and is supplied to the back massage unit 4a.

[0031] The connecting portion 61 has a convex connecting portion (connecting portion 61a) and a concave connecting portion (connecting portion 61b), and is connected by connecting the respective connecting portions 61a and 61b to each other. In the present embodiment, the connecting portion 61a is installed on the side of the back massage unit 4a, and the connecting portion 61b is installed on the side of the pipe 60 (more specifically, the second pipe 60b). The connecting portions 61a and 61b will be described later.

[0032] The hole (pipe 60) provided in the backrest 4 is formed in an L shape. Specifically, a short linear hole is opened from the front surface side to the back surface side of the backrest 4, and a long linear hole is opened from the lower surface side to the upper surface side of the backrest 4. An air passage (pipe 60) is formed by opening a through hole at the intersection of the holes with each other. That is, the hole itself can be used as the pipe 60, and the pipe 60 (for example, an air pipe for supplying air to the airbag 100) used in the massage machine 1 can be reduced.

[0033] In addition, in order to prevent the air discharged from the air supply and exhaust device 9 from leaking to the outside of the hole, a coating for preventing air leakage can be applied to the inner periphery of the hole. By applying the coating, the unevenness on the inner periphery of the hole also disappears, so that the air can pass through more smoothly. As Figure 3 (a) shows, when the pipe 60 is provided inside the body support part S (the backrest 4) (formed integrally), the pipe 60 does not protrude to the outside, so the appearance is not damaged. And, as Figure 3 (b) and (c) show, compared with the case where the pipe 60 is integrally formed on the back surface of the body support part S, the thickness in the front-rear direction can be made more compact. And since the pipe 60 can be arranged at the position desired by the manufacturer, even when the number of pipes 60 increases, there is no need to worry about the pipes 60 being wound or twisted with each other.

[0034] The state where the pipe 60 is integrally formed on the back surface of the body support part S (the backrest 4) will be described. As an example, a method of burying a part of the cylindrical pipe 60 in the backrest 4 will be described. As Figure 3 (b) and (c) show, the back massage part 4a (massage part M) provided on the backrest 4 is connected to the air supply and exhaust device 9 via the pipe 60. More specifically, the pipe 60 is the first pipe 60a connected to the air supply and exhaust device 9 and the pipe (the pipe buried in the backrest 4) integrally formed on the back surface of the backrest 4 and connected to the airbag 100, the second pipe 60b. Since the connection relationship between the back massage part 4a and the pipe 60 (the second pipe 60b) is the same as that of Figure 3 (a), the description thereof is omitted.

[0035] A linear hole is penetrated from the front surface side to the back surface side of the backrest 4, and a hollow cylindrical member formed in an L shape is buried in the penetrated hole, and the backrest 4 and the cylindrical member are welded to each other, whereby the cylindrical member can be used as the pipe 60. More specifically, on the back surface of the backrest 4, a semicircular groove is dug from the lower surface side to the upper surface side, one end (the short side) of the cylindrical member is inserted into the hole penetrating the backrest 4, and the cylindrical member (the long side) is fitted to the semicircular groove, whereby the pipe 60 can be integrally formed on the back surface of the backrest 4 (the body support part S).

[0036] The semi-circular groove is provided from the lower surface side of the backrest side 4 to the vicinity of the position where the back massage part 4a is installed, facing the upper surface side. The inner circumference of the groove has substantially the same shape as the outer circumference of the cylindrical member. That is, the inner circumference of the groove can be installed in close contact with the outer circumference (long side dimension) of the cylindrical member. Since the semi-circular groove is dug on the back surface of the backrest 4, a part of the cylindrical member is buried in the back surface of the backrest 4, and the remaining part protrudes from the backrest 4. The protruding part becomes a protruding part 4d that protrudes from the backrest 4 (refer to Figure 3 (b), (c)). In addition, similar to the case of Figure 3 (a), in order to prevent the air discharged from the air supply and exhaust device 9 from leaking to the outside of the hole, a coating for preventing air leakage can be applied to the inner circumference of the hole.

[0037] In addition, the L-shaped cylindrical member is preferably made of the same material as the backrest 4. By forming the member with the same material as the backrest 4 (for example, both members are made of synthetic resin composed of the same raw material, etc.), it can be easily welded (formed integrally). By adopting Figure 3 (b), (c) method, compared with the case of Figure 3 (a), the man-hour for forming integrally can be reduced. In addition, these are just examples. As long as the pipe 60 can be formed integrally with the backrest 4 (body support part S), any structure and any method can be used.

[0038] On the side part of the backrest 4, at a position lower than the center and extending in the left-right direction, a pair of left and right swing shafts (not shown) are provided, and the backrest 4 can recline in the front-rear direction with the swing shafts (not shown) as fulcrums. In addition, although not shown, the reclining of the backrest 4 is performed by driving the driving part. The driving of the driving part is controlled by the control part 7. Regarding the control part 7, it will be described later.

[0039] Figure 4 It is a view showing the body support part S (seat part 3) according to an embodiment of the present invention, Figure 4 (a) is a view of a cross-section cut along the up-down direction as observed from the left side, Figure 4 (b) is a view of a cross-section cut along the left-right direction as observed from the plane, Figure 4 (c) is a view of a cross-section cut along the up-down direction as observed from the left side, Figure 4 (d) is a view of a cross-section cut along the up-down direction as observed from the rear. In addition, the hatched part is the part corresponding to the main body of the seat part 3, which is used to easily understand the relationship with the pipe 60. More specifically, Figure 4 (a), (b) are cross-sectional views showing the state where the pipe 60 is provided inside the body support part S (seat part 3), Figure 4(c) and (d) are cross-sectional views showing the state in which the pipe 60 is provided on the back surface (the lower surface side in the vertical direction) of the body support portion S (seat portion 3).

[0040] [Structure of the seat portion] As Figure 1 shown, the seat portion 3 is composed of a horizontally long rectangular member in the left-right direction. The seat portion 3 is preferably composed of an elastic member such as urethane. By being composed of an elastic member, the seating comfort when the user sits on the seat portion 3 can be improved. On the upper surface of the seat portion 3 (more specifically, the concave portion 3c provided in the seat portion 3), a pair of left and right hip massage portions 3a (massage portion M) for massaging the hips of the user sitting on the seat portion 3 are provided. The hip massage portion 3a is composed of an airbag 100 that expands and contracts by the supply and discharge of air.

[0041] The hip massage portion 3a can also be configured to be able to expand and contract independently on the left and right. In the case of expanding and contracting independently on the left and right, it can be achieved by separately forming pipes on the left and right. And, the structure of the massage portion M disposed on the seat portion 3 is an example and is not limited thereto. For example, a thigh massage portion (not shown) for massaging the thigh portion can be provided, or a total of four can be provided in pairs in the front-rear, left-right directions. And, multiple can also be appropriately combined and disposed respectively, and the number of the hip massage portions 3a disposed is not limited either. As long as the periphery of the user's hips can be massaged.

[0042] The state in which the pipe 60 is integrally formed inside the seat portion 3 (body support portion S) will be described. In addition, if the pipe 60 can be integrally formed on the seat portion 3 (body support portion S), it can be formed by any method. As an example, the case of forming by the method of opening a hole in the seat portion 3 will be described.

[0043] As Figure 4 shown, a concave portion 3c for mounting the hip massage portion 3a is formed on the upper surface of the seat portion 3. The outer periphery of the concave portion 3c is slightly larger than the outer periphery of the hip massage portion 3a. The depth of the concave portion 3c is such that when the hip massage portion 3a is installed, the upper surface of the seat portion 3 and the upper surface of the hip massage portion 3a become substantially the same plane. Thereby, when the hip massage portion 3a is installed in the concave portion 3c, the upper surface of the seat portion 3 and the upper surface of the hip massage portion 3a can be set to be substantially the same plane, and when the user sits on the seat portion 3, the discomfort caused by the hip massage portion 3a abutting against the user can be reduced.

[0044] At the center of the recess 3c, a connecting portion 61 for connecting the hip massage portion 3a and the pipe 60 is provided. More specifically, at the front end of the pipe 60 (the hole provided in the seat portion 3) provided in the seat portion 3, a connecting portion 61b (61) is provided. By directly installing the connecting portion 61b (61) at the front end of the pipe 60 (the side facing the airbag 100) (the hole provided in the seat portion 3), the hip massage portion 3a can be easily attached to and detached from the seat portion 3. The connecting portion 61b (61) will be described later. In addition, in the present embodiment, the case where the hip massage portion 3a is installed in the recess 3c provided in the seat portion 3 has been described, but this is an example and is not limited thereto. For example, it may be configured such that the recess 3c is not provided, and the hip massage portion 3a is directly installed on the seat portion 3.

[0045] As Figure 4 (a) shows, the hip massage portion 3a (massage portion M) provided near the center of the seat portion 3 is connected to the air supply and exhaust device 9 via the pipe 60. More specifically, the pipe 60 is composed of a first pipe 60a connected to the air supply and exhaust device 9 and a pipe (the hole provided in the seat portion 3) integrally formed inside the seat portion 3 and connected to the airbag 100, which is a second pipe 60b. The second pipe 60b and the first pipe 60a are connected via a connecting portion 61 (refer to Figure 11 ). The first pipe 60a and the second pipe 60b will be described later.

[0046] The hip massage portion 3a and the second pipe 60b are connected via a connecting portion 61b (61). That is, the air supply and exhaust device 9 is connected to the first pipe 60a, the first pipe 60a and the second pipe 60b are connected via the connecting portion 61, and the second pipe 60b and the hip massage portion 3a are connected via the connecting portion 61. The air discharged from the air supply and exhaust device 9 passes through the respective pipes 60a, 60b and is supplied to the hip massage portion 3a.

[0047] The connecting portion 61 has a convex connecting portion (connecting portion 61a) and a concave connecting portion (connecting portion 61b), and is connected by connecting the respective connecting portions 61a, 61b to each other. In the present embodiment, the connecting portion 61a is installed on the hip massage portion 3a side, and the connecting portion 61b is installed on the pipe 60 (more specifically, the second pipe 60b) side. The connecting portions 61a, 61b will be described later.

[0048] The hole (pipe 60) provided in the seat portion 3 is formed in a substantially Y shape (refer to Figure 4(b)). Specifically, a short linear hole is formed on the rear surface side of the seat part 3, extending from the center toward the front surface side and branching left and right midway. More specifically, it branches 90 degrees to the left and 90 degrees to the right. The hole branching to the left further bends 90 degrees to the right midway and extends toward the front surface side. The hole branching to the right further bends 90 degrees to the left midway and extends toward the front side. The holes formed by the left and right bends serve as air passages (pipe 60). That is, the hole itself can be used as the pipe 60, and the pipes 60 used in the massage machine 1 (for example, the air pipes for supplying air to the airbag 100) can be reduced.

[0049] Similar to the case of the backrest 4, in order to prevent the air discharged from the air supply and exhaust device 9 from leaking outside the hole, a coating for preventing air leakage can be applied to the inner circumference of the hole. By applying the coating, the unevenness on the inner circumference of the hole also disappears, so that the air can pass through more smoothly. The same coating can be applied to the holes provided in the armrest part 2 (including the armrest part units 6L and 6R) or the footrest part 5 described later.

[0050] As Figure 4 As shown in (a) and (b), when the pipe 60 is provided (integrally formed) inside the body support part S (seat part 3), the pipe 60 is not exposed outside, so the appearance is not damaged. And, as Figure 4 As shown in (c) and (d), compared with the case where the pipe 60 is integrally formed on the back surface of the body support part S, the thickness in the vertical direction can be made more compact. And since the pipe 60 can be arranged at the position desired by the manufacturer, even when the number of pipes 60 increases, there is no need to worry about the pipes 60 winding or twisting with each other.

[0051] A description will be given of the state where the pipe 60 is integrally formed on the back surface of the body support part S (seat part 3). As an example, a method of embedding a part of the cylindrical pipe 60 in the seat part 3 will be described. As Figure 4 As shown in (c) and (d), the hip massage part 3a (massage part M) provided in the seat part 3 is connected to the air supply and exhaust device 9 via the pipe 60. More specifically, the pipe 60 is the first pipe 60a connected to the air supply and exhaust device 9 and the pipe (the pipe buried in the seat part 3) integrally formed on the back surface of the seat part 3 and connected to the airbag 100, the second pipe 60b. Since the connection relationship between the hip massage part 3a and the pipe 60 (the second pipe 60b) is the same as that in Figure 4 (a) and (b), the description thereof will be omitted.

[0052] In Figure 4In cases (c) and (d), a linear hole is drilled through from the back side (bottom side) to the upper surface side (seating surface side) of the seat part 3, and a hollow cylindrical part formed in an L shape is buried in the drilled hole, and the seat part 3 and the cylindrical part are welded to each other, whereby the cylindrical part can be used as the pipe 60. More specifically, on the back surface of the seat part 3, a semicircular groove is dug from the rear to the front, one end (short dimension side) of the cylindrical part is inserted into the hole penetrating the seat part 3, and the cylindrical part (long dimension side) is fitted to the semicircular groove, whereby the pipe 60 can be integrally formed on the back surface of the seat part 3 (body support part S).

[0053] The semicircular groove is provided from the rear of the seat part 3 to the vicinity of the position where the hip massage part 3a is installed. The inner circumference of the groove has substantially the same shape as the outer circumference of the cylindrical pipe 60. That is, the inner circumference of the groove can be fitted to the outer circumference (long dimension side) of the cylindrical part. Since the semicircular groove is dug on the back surface (bottom surface) of the seat part 3, a part of the cylindrical part is buried in the back surface of the seat part 3, and the remaining part protrudes from the seat part 3. The protruding part becomes a raised part 3d protruding from the seat part 3 (refer to Figure 4 (c) and (d)). In addition, similar to the cases of Figure 4 (a) and (b), in order to prevent the air discharged from the air supply and exhaust device 9 from leaking to the outside of the hole, a coating for preventing air leakage can be applied to the inner circumference of the hole. By applying the coating, the unevenness on the inner circumference of the hole also disappears, and the air passes through more smoothly.

[0054] In the present embodiment, the seat part 3 is preferably made of a flexible member such as urethane. By forming the seat part 3 of urethane, the seating comfort when the user sits can be improved. In addition, when the seat part 3 is made of urethane, in the state as it is (only the state where the hole is opened), the air discharged from the air supply and exhaust device 9 may leak to the outside through the fine holes in the urethane. Therefore, it is preferable to apply a coating for preventing air leakage to the periphery of the hole. The raw material used for the coating is preferably a flexible member such as rubber or elastomer, which is the same as urethane. By applying the coating to the inner circumference of the hole, the hole itself can be used as the pipe 60.

[0055] Regarding the seat part 3 and the pipe 60 integrally formed on the seat part 3, by being made of a flexible member, the pipe 60 can be laid even in the bent part or the bent part, and the pipe 60 can be arranged at a position desired by the manufacturer. That is, even when the number of pipes 60 increases, there is no need to worry about the pipes 60 being entangled or twisted with each other. And the discomfort felt by the user when sitting on the seat part 3 can be reduced.

[0056] In addition, the substantially Y-shaped cylindrical member is preferably made of the same material as the seat portion 3. By forming with the same member as the seat portion 3 (for example, both members are made of synthetic resin composed of the same raw material, etc.), it can be easily welded (formed integrally). By adopting Figure 4 (c) and (d) methods, compared with the cases of Figure 4 (a) and (b), the man-hours for forming integrally can be reduced. In addition, these are just examples. As long as the pipe 60 can be formed integrally with the seat portion 3 (body support portion S), any structure and any method can be used.

[0057] [Structure of armrest portion] Figure 5 FIG. is a view showing the body support portion S (right armrest portion 2 including the armrest unit 6R) according to an embodiment of the present invention, Figure 5 (a) is a view of a cross-section cut along the vertical direction as observed from the front, Figure 5 (b) is a view of a cross-section cut along the vertical direction as observed from the front. In addition, the hatched portion is the portion corresponding to the right armrest portion 2 including the armrest unit 6R, which is used to easily understand the relationship with the pipe 60. Figure 6 FIG. is a view showing the body support portion S (right armrest portion 2 including the armrest unit 6R) according to another embodiment of the present invention, Figure 6 (a) is a view of a cross-section cut along the vertical direction as observed from the front, Figure 6 (b) is a view of a cross-section cut in the vertical direction as observed from the front.

[0058] More specifically, Figure 5 (a) is a cross-sectional view showing the state where the pipe 60 is disposed inside the right armrest portion 2 (body support portion S) including the armrest unit 6R, Figure 5 (b) is a cross-sectional view showing the state where the pipe 60 is disposed on the side surface (outer side surface in the left-right direction) of the right armrest portion 2 (body support portion S) including the armrest unit 6R. And, in the present embodiment, as Figure 8 shown, an example where the connecting portion 61 and the leakage prevention portion 70 are separately formed is described. In addition, the connecting portion 61 provided on each body support portion S can be of the Figure 8 type (split type), as Figure 9 shown, or can also be of the type where the connecting portion 61 and the leakage prevention portion 70 are integrated. The structures of the connecting portion 61 and the leakage prevention portion 70 will be described later.

[0059] In addition, a pair of left and right armrest unit 6 is provided with respect to the massage machine 1. More specifically, they are provided on the upper surface of the armrest 2 of the massage machine 1 in such a manner that their openings face each other when viewed from the front (refer to Figure 1 ). The left and right armrest units 6L and 6R have the same structure that is symmetrical left and right. Therefore, hereinafter, the right armrest unit 6R will be taken as an example for description, and the description of the structure of the left armrest unit 6L will be omitted.

[0060] [Structure around the armrest (Pattern 1)] Pattern 1 is a pattern in a state where the armrest unit 6R is mounted on the upper surface of the armrest 2 configured in an I shape (refer to Figure 5 ). That is, it is a pattern in which the U-shaped armrest unit 6R and the I-shaped armrest 2 are combined. As shown in Figure 1 and Figure 5 , a pipe 60 (more specifically, the second pipe 60b) is integrally formed inside the armrest 2. One end of the second pipe 60b is connected to the air supply and exhaust device 9 via the connecting portion 61 (refer to Figure 11 ), and a connecting portion 61b (concave connecting portion) is installed at the front end of the other end (the side connected to the armrest unit 6R). The second pipe 60b is a hole provided in the armrest 2. More specifically, the second pipe 60b is a hole opened from the lower surface side to the upper surface side of the armrest 2. The connecting portion 61b (concave connecting portion) is connected (connected) to the connecting portion 61a (convex connecting portion) protruding from the lower wall side of the armrest unit 6R (body support portion S).

[0061] As shown in Figure 5 (a), the armrest unit 6R is formed in a substantially U shape composed of a lower wall, side walls, and an upper wall. Arm massage portions 6a (massage portions M) are respectively installed on the upper wall and the lower wall. The arm massage portions 6a (massage portions M) are connected to the air supply and exhaust device 9 via the pipe 60. More specifically, the pipe 60 is the first pipe 60a connected to the air supply and exhaust device 9, and the second pipe 60b of the airbag 100 composed of a pipe integrally formed inside the armrest unit 6R and a pipe integrally formed inside the armrest 2. The second pipe 60b is connected to the first pipe 60a via the connecting portion 61 (refer to Figure 11 ).

[0062] A connecting portion 61b (concave connecting portion) is installed at the front end of a pipe 60 (a hole formed in the upper wall) provided on the upper wall of the armrest unit 6R, and is connected (coupled) to a connecting portion 61a (convex connecting portion) provided on the arm massage portion 6a. A connecting portion 61b (concave connecting portion) is installed at the front end of a pipe 60 (a hole formed in the lower wall) provided on the lower wall, and is connected (coupled) to a connecting portion 61a (convex connecting portion) provided on the arm massage portion 6a.

[0063] In each wall (upper wall, side wall, lower wall) constituting the armrest unit 6R, holes are formed along the shape of each wall. That is, the holes also have a U-shaped configuration. Near the center of the upper wall, a hole is formed from the lower surface side toward the upper surface side, bent 90 degrees midway and extended (extended toward the side wall). Moreover, when approaching the vicinity of the center of the side wall, it is bent 90 degrees, and the hole extends from the upper surface side toward the lower surface side. When approaching the lower surface side of the side wall, it is further bent 90 degrees and bent and extended toward the right side in the left-right direction (extended toward the direction close to the user). The holes provided in each wall (upper wall, side wall, lower wall) function as the pipe 60 (second pipe 60b).

[0064] Arm massage portions 6a (massage portions M) composed of airbags 100 are detachably installed on the upper wall and the lower wall, respectively. The air discharged from the air supply and exhaust device 9 is supplied to the arm massage portions 6a through the pipes 60 (first pipe 60a, second pipe 0b). That is, the user can massage the arm (forearm) by inserting the arm into the concave portion of the armrest unit 6R formed in a substantially U shape.

[0065] In addition, in the present embodiment, the case where a connecting portion 61b (concave connecting portion) is provided at the front end of the pipe 60 (a hole formed in the upper wall) and a connecting portion 61a (convex connecting portion) is provided on the arm massage portion 6a has been described. However, a connecting portion 61a (convex connecting portion) may be provided at the front end of the pipe 60 (a hole formed in the upper wall), and a connecting portion 61b (concave connecting portion) may be provided on the arm massage portion 6a. Any structure that can easily attach and detach (connect / couple) the arm massage portion 6a to the pipe 60 is acceptable.

[0066] The pipe 60 is integrally formed with the armrest unit 6R (body support portion S). As an example, based on the method of excavating a groove when molding the armrest unit 6R. As Figure 1As shown, the armrest unit 6R is configured to be long in the front-rear direction to support the user's forearm. At this time, the armrest unit 6R is structured to be divided into two parts in the front and rear. On the rear surface of the front armrest unit 6R, a semi-circular groove is dug along the shape of the armrest unit 6R (U-shaped). On the front surface of the rear armrest unit 6R, a semi-circular groove is also dug along the shape of the armrest unit 6R (U-shaped). By welding them to each other, a circular hole is integrally formed inside the armrest unit 6R. Thus, this hole itself can be utilized as the pipe 60, and the length of the pipe 60 used in the massage machine 1 can be reduced (for example, the length of the air pipe for supplying air to the airbag 100 can be shortened).

[0067] In addition, in order to prevent air from leaking to the outside, the periphery of the hole can also be coated. By coating, the unevenness of the hole also disappears, and air can pass through more smoothly. As Figure 5 (a) shows, by arranging the pipe 60 inside the body support part S (armrest unit 6R, right armrest 2), the pipe 60 will not be exposed to the outside. Therefore, compared with the case where the pipe 60 is arranged on the back or side of the body support part S, the thickness in the front-rear direction or the left-right direction can be made more compact. And it will not damage the appearance. Also, since the pipe 60 can be arranged at the position desired by the manufacturer, even when the number of pipes 60 increases, there is no need to worry about the pipes 60 being entangled or twisted with each other.

[0068] Also, it can be configured to integrally form the pipe 60 on the side of the right armrest 2 (body support part S). As an example, a method of embedding a part of the cylindrical pipe 60 in the side of the right armrest 2 will be described. As Figure 5 (b) shows, the arm massage part 6a (massage part M) in the armrest unit 6R provided on the right armrest 2 is connected to the air supply and exhaust device 9 via the pipe 60. More specifically, the pipe 60 is the first pipe 60a connected to the air supply and exhaust device 9 and the second pipe 60b which is integrally formed inside the armrest unit 6R and on the side of the right armrest 2 (right side in the left-right direction) (the pipe buried in the right armrest 2) and is connected to the airbag 100. The connection relationship between the arm massage part 6a and the pipe 60 (the second pipe 60b) is the same as that in Figure 3 (a) etc., so the description is omitted.

[0069] A semi-circular groove is dug on the side of the right armrest 2, and a hollow cylindrical member is buried in the semi-circular groove, and the right armrest 2 and the cylindrical member are welded to each other, whereby the cylindrical member can be utilized as the pipe 60. More specifically, a semi-circular groove is linearly dug upward from below on the side surface of the right armrest portion 2, and a cylindrical member (long side) is closely attached to the semi-circular groove, whereby the pipe 60 can be integrally formed on the side surface of the right armrest portion 2 (body support portion S).

[0070] The semi-circular groove is provided upward from the lower part of the right armrest portion 2 to a position near the contact with the lower wall of the armrest unit 6R. The inner circumference of the groove has substantially the same shape as the outer circumference of the cylindrical member. That is, the inner circumference of the groove can be closely attached and installed to the outer circumference (long side) of the cylindrical member. Since a semi-circular groove is dug on the side surface of the right armrest portion 2, a part of the cylindrical member is buried in the back surface of the right armrest portion 2, and the remaining part protrudes from the right armrest portion 2. The protruding part becomes a protruding portion 2d protruding from the right armrest portion 2 (refer to Figure 5 (b)). In addition, similar to the case of Figure 3 (a), in order to prevent the air discharged from the air supply and exhaust device 9 from leaking to the outside of the hole, a coating for preventing air leakage can be applied to the inner circumference of the hole.

[0071] In addition, in the case of Figure 5 (a), a hole (pipe 60) is integrally formed near the center of the armrest portion 2, but in the case of Figure 5 (b), a hole (pipe 60) is integrally formed on the side surface of the armrest portion 2. That is, the position of the connecting portion 61a on the armrest unit 6R side also changes corresponding to the position of the hole (pipe 60) on the armrest portion 2 side. More specifically, the connecting portion 61a (convex connecting portion) protruding from the lower wall of the armrest unit 6R is offset to the right in the left-right direction of the lower wall.

[0072] [Structure around the armrest portion (Mode 2)] Mode 2 is a mode in which the armrest portion 2 is configured in an L shape when viewed from the front and the armrest unit 6R is installed in the cut portion of the L shape (refer to Figure 6 ). That is, it is a mode in which the U-shaped armrest unit 6R and the L-shaped armrest portion 2 are combined. As Figure 1 、 Figure 6 shown, a pipe 60 (more specifically, the second pipe 60b) is integrally formed inside the armrest portion 2. One end of the second pipe 60b is connected to the air supply and exhaust device 9 via the connecting portion 61 (refer to Figure 11 ), and a connecting portion 61b (concave connecting portion) is installed at the front end of the other end (the side connected to the armrest unit 6R). The second pipe 60b is a hole provided in the armrest portion 2. More specifically, the second pipe 60b is a hole formed from the lower surface side to the upper surface side of the armrest portion 2. The connecting portion 61b (concave connecting portion) is connected (joined) to the connecting portion 61a (convex connecting portion) protruding from the lower wall side of the armrest unit 6R (body support portion S).

[0073] Regarding the structure of the armrest unit 6R, except for the difference in the position of the connecting portion 61a (convex connecting portion) used for connecting (joining) to the connecting portion 61b (concave connecting portion) of the armrest portion 2, since it has the same structure as in Mode 1, for the parts with the same structure as the Figure 5 armrest unit 6R, the description is omitted.

[0074] In the case of Mode 1, the connecting portion 61a (convex connecting portion) protruding from the armrest unit 6R protrudes downward from the lower wall constituting the armrest unit 6R. On the other hand, in the case of Mode 2, the connecting portion 61a (convex connecting portion) protruding from the armrest unit 6R protrudes outward (right side) in the left - right direction from the side wall constituting the armrest unit 6R.

[0075] More specifically, in the case of Mode 2, the right - hand armrest portion 2 is configured to be L - shaped when viewed from the front. The armrest unit 6R is installed at the L - shaped portion. The upper surface of the right - hand armrest portion 2 and the upper surface of the armrest unit 6R are substantially on the same plane. Different from the case of Mode 1, the hole (pipe 60) integrally formed inside the right - hand armrest portion 2 is offset to the right in the left - right direction. At this time, the hole (pipe 60) extends upward from below the armrest portion 2 and bends 90 degrees in the direction closer to the user midway. The bending position is the position facing the connecting portion 61a (convex connecting portion) provided on the side wall of the armrest unit 6R. The connecting portion 61b (concave connecting portion) is installed at the front end of the hole (pipe 60). That is, the armrest unit 6R is connected (joined) to the right - hand armrest portion 2 via the connecting portion 61.

[0076] In addition, similar to the case where the pipe 60 is formed in the seat portion 3 or the backrest portion 4, in order to prevent air from leaking to the outside, in both Mode 1 and Mode 2, the periphery of the hole can be coated. And, as Figure 6As shown in (b), by disposing the pipe 60 on the side surface of the body support portion S (right armrest portion 2), it is also possible to integrally form the pipe 60 with the right armrest portion 2 (body support portion S). The method of integral formation is based on the same method as in the case of integrally forming on the side surface of the seat portion 3 or the backrest portion 4. That is, the method is as follows: A semi-circular groove is dug on the side surface of the right armrest portion 2, a hollow cylindrical member is buried in the semi-circular groove, and the right armrest portion 2 and the cylindrical member are welded to each other, thereby using the cylindrical member as the pipe 60. Regarding this method, since it has been described, the raised portions 3d and 4d are renamed as the raised portion 2d, and the description is omitted.

[0077] [Structure of the footrest portion] Figure 7 FIG. is a cross-sectional view taken by cutting the body support portion S (footrest portion 5) according to an embodiment of the present invention in the left-right direction as viewed from a plane. Figure 7 (a) is a view showing a state constituted by pipes that are different on the left and right sides respectively. Figure 7 (b) is a view showing a state constituted by pipes that are different on the left and right sides respectively. Figure 7 (c) is a view showing a state constituted by a pipe that is common to the left and right sides. In addition, Figure 7 (a), (b) and Figure 7 (c) differ in the number of connecting portions 61a protruding from the footrest portion 5. Regarding the details, they will be described later.

[0078] As Figure 1 , Figure 7 shown, the footrest portion 5 has a recess 5b into which the user's leg can be inserted. The recess 5b is composed of inner walls on the left and right and a bottom wall connecting the left and right inner walls. The recesses 5 are provided in pairs on the left and right. On the inner walls on both sides of the recess 5b, foot massage portions 5a (massage portion M) for massaging the user's legs are respectively provided. The foot massage portion 5a is composed of an airbag 100 that expands and contracts by supplying and discharging air.

[0079] One foot massage portion 5a is provided on each of the inner walls on both sides of the recess 5b on the right side, and one foot massage portion 5a is provided on each of the inner walls on both sides of the recess 5b on the left side. Each foot massage portion 5a can be configured to be able to expand and contract independently. In this case, it can be achieved by forming the left and right pipes 60 with pipes that are different from each other respectively. And a sole massage portion (not shown) for massaging the user's sole may be provided on the bottom surface of the recess 5b.

[0080] The footrest portion 5 is installed on the front side of the seat portion 3. More specifically, the footrest portion 5 is installed on the seat portion 3 via a swing axis (not shown) extending in the left-right direction. A drive portion (not shown) for swinging the footrest portion 5 relative to the seat portion 3 in the up-down direction is located on the back surface of the footrest portion 5. By driving the drive portion (not shown), with the swing axis (not shown) extending in the left-right direction as a fulcrum, the footrest portion 5 can be swung relative to the seat portion 3 in the up-down direction. The drive of the drive portion (not shown) is controlled by the control portion 7. Regarding the control portion 7, it will be described later. Additionally, an extension member (not shown) that can be moved in the front-back direction relative to the seat portion 3 may be provided on the footrest portion 5.

[0081] As Figure 7 (a) shows, the foot massage portion 5a (massage portion M) is connected to a pipe 60 formed inside the footrest portion 5 via a connecting portion 61. The pipe 60 is integrally formed inside the footrest portion 5 (body support portion S). As an example, based on the method of digging a groove when molding the footrest portion 5. The footrest portion 5 is configured to be long in the up-down direction (the length direction of the leg). When molding the footrest portion 5, the footrest portion 5 is divided into two parts. Specifically, the footrest portion 5 is vertically divided into two parts in the form of an upper footrest portion and a lower footrest portion. On the bottom surface of the upper footrest portion, a semicircular groove is dug along the shape of the footrest portion 5 (U-shaped), and on the upper surface of the lower footrest portion (the surface opposite to the upper footrest portion), a semicircular groove is also dug along the shape of the footrest portion 5 (U-shaped). By welding them to each other, a circular hole is formed in the footrest portion 5. Thus, this hole itself can be utilized as the pipe 60. That is, the number of pipes 60 used in the massager 1 can be reduced.

[0082] Holes are respectively formed on the inner walls on the left and right sides of the concave portion 5b on the right side of the footrest portion 5 and on the inner walls on the left and right sides of the concave portion 5b on the left side, and a connecting portion 61b (concave connecting portion) is installed at the front end of the hole. A connecting portion 61a (convex connecting portion) is installed near the center of the foot massage portion 5a. That is, by connecting (linking) the connecting portion 61a (convex connecting portion) with the connecting portion 61b (concave connecting portion) installed in the hole on the inner wall, the air supplied from the air supply and exhaust device 9 passes through the pipe 60 and is supplied to the foot massage portion 5a, enabling massage of the left and right sides of the user's leg.

[0083] A connecting portion 61a (convex connecting portion) protruding rearward is installed on the back surface (the bottom wall forming the concave portion 5b) of the footrest portion 5. By connecting the pipe 60 extending from the air supply and exhaust device 9 to this connecting portion 61a, the air supplied from the air supply and exhaust device 9 can be supplied to the foot massage portion 5a. As Figure 7As shown in (a), by disposing the pipe 60 inside the body support portion S (the footrest portion 5), the pipe 60 is not exposed to the outside. Therefore, compared with the case where the pipe 60 is disposed on the back or side of the body support portion S (refer to Figure 7 (b)), it is possible to make the thickness in the front-rear direction or the left-right direction compact. Also, the appearance is not impaired. And since the pipe 60 can be arranged at a position desired by the manufacturer, even when the number of pipes 60 increases, there is no need to worry about the pipes 60 being entangled or twisted with each other.

[0084] And, as Figure 7 (c) shows, the pipe 60 connected to the left and right foot massage portions 5a can also be constituted by one pipe 60. By being constituted by one pipe, the connecting portion 61a protruding from the bottom wall of the footrest portion 5 becomes one, so that the manufacturing cost can be reduced. In addition, the method of disposing the pipe 60 can be achieved by the same method as Figure 7 (a).

[0085] And, as Figure 7 (b) shows, by disposing the pipe 60 on the side surface (the side surface side and the back surface side) of the body support portion S (the footrest portion 5), it is also possible to configure the pipe 60 to be integrally formed with the footrest portion 5 (the body support portion S). As an example, based on the same method as in Figure 7 (a), that is, the method of digging a groove when molding the footrest portion 5.

[0086] More specifically, the footrest portion 5 is configured to be divided into two parts up and down, and a semicircular groove is dug through the bottom surface of the upper footrest portion 5 and the inner walls on the outer sides in the left-right direction of the left and right concave portions 5b. An L-shaped groove is dug on the inner walls on the inner sides in the left-right direction of the left and right concave portions 5b. The substantially U-shaped cylindrical pipe 60 is inserted into this groove. A groove having the same shape as the bottom surface of the upper footrest portion 5 is also dug on the upper surface of the lower footrest portion 5, and by welding the upper footrest portion 5 and the lower footrest portion 5 to each other, the pipe 60 is integrally formed with the footrest portion 5. Thus, this hole itself can be used as the pipe 60. That is, the number of pipes 60 used in the massage machine 1 can be reduced.

[0087] At this time, the U-shaped member is preferably made of the same material as the footrest portion 5. By forming the footrest portion 5 and the U-shaped member of the same member, welding can be simply performed. And by adopting this method, compared with the case where the pipe 60 is disposed inside the body support portion S (the footrest portion 5), the man-hours for integral formation can be reduced. In addition, these are examples, and as long as the pipe 60 can be integrally formed with the footrest portion 5 (the body support portion S), any structure and any method may be used.

[0088] In this embodiment, as Figure 8As shown, the case where the connecting portion 61 and the leakage prevention portion 70 are separately formed is taken as an example for explanation. However, as Figure 9 shown, the connecting portion 61 and the leakage prevention portion 70 may also be integrated. The structures of the connecting portion 61 and the leakage prevention portion 70 will be described later.

[0089] [Structure of the control unit] Figure 2 is a block diagram of the massage machine 1 according to an embodiment of the present invention. As Figure 2 shown, in the massage machine 1, a massage mechanism 99, an air supply and exhaust device 9, and a control unit 7 composed of a microcomputer or the like for operating a drive unit (not shown) are provided. The drive unit is used to swing the backrest 4 and the footrest 5. The control unit 7 is provided below the seat portion 3 and is connected to a controller 8 operated by the user. Various massage actions are performed by the user operating the controller 8.

[0090] [Structure of the air supply and exhaust device] As Figure 2 , Figure 11 shown, the air supply and exhaust device 9 is composed of a pump 9a for supplying air to each massage portion M constituted by an airbag 100, a valve 9b connecting each massage portion M and the pump 9a, and a short pipe 9c connecting the pump 9a and each valve 9b. By opening / closing (ON / OFF) the valve 9b, air can be supplied to each massage portion M constituted by an airbag or discharged from each massage portion M. That is, by opening the valve 9b, the air flow path can be ensured, and air can be supplied to each massage portion M. Further, by closing the valve 9b, the air that has entered each massage portion M can be discharged.

Figure 9 is a view showing the mounting relationship between the airbag 100 and the pipe 60 according to an embodiment of the present invention, and is a view showing that the connecting portion 61 and the leakage prevention portion 70 are integrated. Figure 10 is a view showing the leakage prevention portion 70 according to an embodiment of the present invention, Figure 10 (a) is a cross-sectional view showing the state where the pipe 60 is connected, Figure 10 (b) is a cross-sectional view showing the process of connecting the pipe 60, Figure 10 (c) is a cross-sectional view showing the state where the pipe 60 is not connected. Figure 11 is a perspective view showing the connection state of the pipe from the air supply and exhaust device 9 of the massage machine 1 according to an embodiment of the invention to the arm massage portion 6a.

[0092] [Structure of the pipe] like Figure 8 , Figure 9 , Figure 11 As shown, the piping 60 is composed of a first piping 60a connected to the air supply and exhaust device 9, a second piping 60b connected to the airbag 100, and a connecting portion 61 connecting the first piping 60a and the second piping 60b. By combining the piping 60 into a plurality of components, the piping 60 can be laid corresponding to various shapes. In addition, Figure 8 , Figure 9 1 is a diagram showing the connection (coupling) relationship between the airbag 100 and the second piping 60b. The connection (coupling) relationship between the first piping 60a and the second piping 60b is shown in FIG. Figure 11 middle.

[0093] [Structure of the first pipe] The pipe 60 has a first pipe 60a connected to the air supply and exhaust device 9. The first pipe 60a is a pipe for conveying air supplied from the air supply and exhaust device 9 to the second pipe 60b. The first pipe 60a is preferably made of a flexible member such as rubber. By using a flexible member in the first pipe 60a constituting the pipe 60, the first pipe 60b can be bent, and the pipe 60 can be effectively installed.

[0094] [Structure of the second pipe] The piping 60 includes a second piping 60b connected to the airbag 100. The second piping 60b is a piping 60 integrally formed on the back side or inside the body support portion S, and is a piping for conveying air supplied from the air supply and exhaust device 9 via the first piping 60a to the airbag 100. By integrally forming the second piping 60b constituting the piping 60 on the back side or inside the body support portion S, the length of the component required as the piping 60 can be shortened, or the required component itself can be reduced.

[0095] [Structure of the connecting part] The pipe 60 has a connection portion 61 that connects the first pipe 60a and the second pipe 60b. The connection portion 61 includes two types: a male connection portion 61a and a female connection portion 61b. By connecting the male connection portion 61a and the female connection portion 61b, the first pipe 60a and the second pipe 60b constituting the pipe 60 can be connected to each other. The male connection portion 61a may be provided at one end of the first pipe 60a, or at one end of the second pipe 60b. Any combination is acceptable as long as the male connection portion 61a and the female connection portion 61b are connected to each other.

[0096] [Structure of leakage prevention unit] like Figures 8 to 10 As shown, the second pipe 60b (pipe 60) is provided with a leakage prevention portion 70 for preventing air leakage.Figure 8 FIG. Figure 8 is a view showing a state in which the leak prevention portion 70 is provided on the body support portion S side. Figure 9 FIG. Figure 9 is a view showing a state in which the leak prevention portion 70 is provided on the massage portion M (airbag 100) side. As Figure 8 shown, a mortar-shaped recess 30 is provided on the body support portion S. The leak prevention portion 70 and the connecting portion 61 are attached to the recess 30.

[0097] Inside the body support portion S, a pipe 60 (second pipe 60b) formed of holes is provided. More specifically, a mortar-shaped recess 30 whose both sides approach each other as it goes downward is provided near the center of the body support portion S, and the second pipe 60b is located at the position of the bottom point of the recess 30. The inclination angle of the recess 30 is the same as that of the front end of the connecting portion 61a. More specifically, a concave connecting portion 61b is attached to the second pipe 60b (pipe 60). A convex connecting portion 61a protruding downward is attached to the airbag 100.

[0098] A connecting portion 61 is attached to the front end of the second pipe 60b. More specifically, a concave connecting portion 61b is attached. A leak prevention portion 70 for preventing air leakage is provided on the upper surface of the connecting portion 61. As an example, the leak prevention portion 70 is an annular rubber member. When the connecting portions 61 are connected to each other (the convex connecting portion 61a and the concave connecting portion 61b are connected), the leak prevention portion 70 functions to fill the gap of the connecting portion 61. Thereby, when air is supplied from the air supply and exhaust device 9 to the airbag 100, it is possible to prevent air from leaking from the connection portion of the pipe 60 (first pipe 60a and / or second pipe 60b). In addition, in the present embodiment, the case where the leak prevention portion 70 is provided on the second pipe 60b has been described, but this is only an example and is not limited thereto. For example, the leak prevention portion 70 may be provided on the first pipe 60a, or the leak prevention portion 70 may be provided on both the first pipe 60a and the second pipe 60b.

[0099] And, as Figure 9 , Figure 10 shown, a coupler can be used as the leak prevention portion 70. Figure 9 , Figure 10 The leak prevention portion 70 (hereinafter referred to as "coupler") in FIGS. Figure 9 to Figure 10 is composed of a so-called one-touch coupler. The one-touch coupler is a coupler in which the convex coupler is inserted into the concave coupler and the couplers are connected to each other.

[0100] Figure 10(a) is a cross-sectional view showing the state where the pipe 60 is connected (the state where the male coupler is inserted into the female coupler). Figure 10 (b) is a cross-sectional view showing the process of connecting the pipe 60 (the state when the male coupler is being inserted into the female coupler). Figure 10 (c) is a cross-sectional view showing the state where the pipe 60 is not connected (the state before the male coupler is inserted into the female coupler).

[0101] The male coupler will be described. As Figure 10 (c) shows, the male coupler is provided at the end of the pipe 60. More specifically, it is integrally formed with the connecting portion 61a provided at the end of the pipe 60. The male coupler has a coupler body 63 that extends straight from the pipe 60 and a plurality of uneven portions 62 provided around the coupler body 63. The coupler body 63 has a hollow structure and tapers towards the front end. The plurality of uneven portions 62 are formed on the surface of the connecting portion 61a.

[0102] The female coupler will be described. As Figure 10 (c) shows, the female coupler is provided at the end of the connecting portion 61b. More specifically, it is integrally formed with the connecting portion 61b. The female coupler is configured in a cylindrical shape. The inner diameter of the female coupler is slightly larger than the outer diameter of the connecting portion 61a of the male coupler. Therefore, when the male coupler is inserted into the female coupler, the couplers are closely fitted to each other.

[0103] Near the center of the female coupler, a pair of protrusions 70c are provided at a predetermined interval. Between the pair of protrusions 70c, a sphere 70b for engaging and locking with the concave portions of the plurality of uneven portions 62 provided on the male coupler and a spring 70a for pushing the sphere 70b in a direction away from the wall of the female coupler are provided. The front end of the protrusion 70c is bent to prevent the sphere 70b from flying out. More specifically, the front ends of the pair of protrusions 70c are bent towards each other. The spring 70a, the sphere 70b, and the protrusions 70c are provided in a vertically paired manner. In addition, the number of the protrusions 70c is an example and is not limited thereto. For example, the protrusions 70c can be provided in a horizontally paired manner, or can be provided in a vertically and horizontally paired manner respectively. By increasing the number of the protrusions 70c, the locking accuracy can be improved.

[0104] A mortar-shaped groove 70d is provided at the front end of the connecting portion 61b. The groove 70d is consistent with the shape of the front end of the male coupler body 63 (tapering towards the female coupler side from the pipe 60 side). By making the shapes consistent, the degree of close fit between the couplers is improved, and air leakage to the outside can be prevented.

[0105] When the convex coupler is inserted into the concave coupler, the sphere 70b of the concave coupler is pushed out in the vertical direction by the plurality of uneven portions 62 of the convex coupler (refer to Figure 10 (b)). More specifically, in the concave portion, the sphere 70b is pushed out by the spring 70a in the direction closer to the coupler main body 63, and in the convex portion, the sphere 70b is pushed out by the convex portion in the direction away from the coupler main body 63. In this state, if the convex coupler is further brought closer to the concave coupler, the front end portion of the convex coupler main body 63 coincides with the groove 70d. At this time, the recessed portion of the uneven portion 62 comes to a position opposed to the sphere 70b. Since the sphere 70b is urged by the spring 70a, the recessed portion engages with the sphere 70b so that the connection between the couplers is not easily released. Accordingly, when air is supplied from the air supply and exhaust device 9 to the airbag 100, it is possible to prevent air from leaking from the connection portion of the pipe 60 (the first pipe 60a and / or the second pipe 60b).
