Fig. 5 is a perspective view showing a state in which the massage arm of the first massage unit to which the present application is applied is in a specific position.

[0053] The first massage unit 1 to which the present embodiment is applied is mounted to a seat section of a massage machine described below, for example, for massaging a user's buttocks. As shown in Figs. 1 and 2, the first massage unit 1 is provided with a main body section 11, a massage section 12, a drive section 13, a detection section 14, and a control section (not shown).

[0054] As shown in FIGS. 1 to 3, the main body 11 includes a core frame 111 and a support structure 112. The core frame 111 includes first to fourth side walls 111a to 111d that form a housing space S in which the massage section 12 is housed, and first to fourth mounting sections 111e to 111h formed at upper ends of the first to fourth side walls 111a to 111d, respectively.

[0055] The support structure 112 is mounted to the core frame 111 and has a support surface 112S on which a user sits. Here, the support surface on which the user sits is formed by an outer surface of the support structure 112. However, it should be understood that in the case where the first massage unit 1 is mounted to a massage machine such as a handheld massager that does not require a support for a body part, the outer surface of the support structure 112 can be simply referred to as a contact surface.

[0056] The support structure 112 includes a first support body 112a, a second support body 112b, a first belt member 112c supported between the first support body 112a and the second support body 112b, a pair of seat cushions 112d, and a second belt member 112e supported between the pair of seat cushions 112d.

[0057] The first belt member 112c and the second belt member 112e are orthogonal to each other and formed in a cross shape. As a material that constitutes the first and second belt members, for example, a woven belt or the like can be listed.

[0058] In the present embodiment, the first support body 112a is fixed to the first mounting section 111e by screw fastening, for example, the second support body 112b is fixed to the third mounting section 111g by screw fastening, for example, and the pair of seat cushions 112d are fixed to the second and fourth mounting sections 111f and 111h, respectively, by screw fastening, for example. However, the mounting method of the first support body, the second support body, and the pair of seat cushions is not limited to screw fastening, and can be any method such as adhesion, welding, or the like.

[0059] As shown in FIGS. 1 and 2, the massage section 12 is housed in the housing space S of the core frame 111.

[0060] The massage section 12 includes two first massage members 121, two second massage members 122, two first massage arms 123 that support the first massage members 121, respectively, two second massage arms 124 that support the second massage members 122, respectively, a first side fitting section 125 connected to the first massage arms 123 and fitted to a first side eccentric wheel described below, and a second side fitting section 126 connected to the second massage arms 124 and fitted to a second side eccentric wheel described below. Also, the number of the first massage members is not limited to two, and can be one or more than three, and similarly, the number of the second massage members is not limited to two, and can be one or more than three.

[0061] The first massage arm 123 and the second massage arm 124 are arranged at a predetermined angle in the circumferential direction, thereby constituting a scissor structure. In this case, by reciprocating swing of the first massage arm and the second massage arm, it is possible to realize kneading massage to the user's buttocks.

[0062] In addition, in Figs. 1 to 3, an example in which the first massage member 121 and the second massage member 122 each include a pair of massage balls arranged side by side is illustrated. In addition, in Figs. 4 and 5, an example in which the first massage member 121 and the second massage member 122 each include only one massage ball is illustrated. Further, although not illustrated, the first massage member and the second massage member can include two or more pairs of massage balls. In this way, by flexibly setting the number of massage balls as needed, it is possible to realize various kneading operations.

[0063] The massage section 12 is driven by the drive section 13 to reciprocally swing the two first massage members 121 and the two second massage members 122 to massage the user's buttocks. As a manner in which the two first massage members and the two second massage members reciprocally swing, for example, a manner in which the two first massage members are simultaneously swung upward or downward and the two second massage members are simultaneously swung upward or downward, a manner in which the two first massage members and the two second massage members reciprocally swing in a manner of simultaneous upward swing or simultaneous downward swing, and the like can be cited.

[0064] As illustrated in Fig. 3, the drive section 13 is provided with a motor 131, a worm 132 as a power transmission mechanism, a rotation shaft 133, and two double-headed eccentric wheels 134.

[0065] The motor 131 is installed in a motor seat 135 fixed to the core frame 111, and includes an output shaft.

[0066] The worm 132 functions as a mechanism that transmits the driving force of the motor 131 to the rotation shaft 133 to rotate the rotation shaft 133. The worm 132 is fixed to the substantially center of the rotation shaft 133 via a bearing 136. The worm 132 is connected to the output shaft of the motor 131, so that the worm 132 is rotated by receiving the driving force of the motor 131 and rotates the rotation shaft 133.

[0067] In addition, the worm 132 can be housed in a case composed of a first case 137 on the upper side and a second case 138 on the lower side.

[0068] The rotation shaft 133 is rotatably erected between the second side wall 111b and the fourth side wall 111d of the core frame 111 via a shaft sleeve 139.

[0069] Two double-headed eccentric wheels 134 are fixed to the rotating shaft 133 and are located on both sides of the turbine 132. The double-headed eccentric wheels 134 function as mechanisms that rotate in synchronization with the rotating shaft 133 to swing the first and second massage members 121 and 122 back and forth. The double-headed eccentric wheels 134 include a middle wheel 1341, a first side eccentric wheel 1342 formed on one side in the axial direction of the middle wheel 1341, and a second side eccentric wheel 1343 formed on the other side in the axial direction of the middle wheel 1341. The first side eccentric wheel 1342 is located on the upper side in the radial direction of the middle wheel 1341, and the second side eccentric wheel 1343 is located on the lower side in the radial direction of the middle wheel 1341 (see FIG. 3). That is, the first side eccentric wheel 1342 and the second side eccentric wheel 1343 are arranged to be offset in the radial direction of the middle wheel 1341.

[0070] In order to more reliably swing the first and second massage arms 123 and 124 upward or downward at the same time during massage, the angle difference between the first side eccentric wheel 1342 and the second side eccentric wheel 1343 is preferably less than 180°, and more preferably in the range of 60° to 120°. In the present embodiment, the angle difference between the first side eccentric wheel 1342 and the second side eccentric wheel 1343 is set to, for example, 88°.

[0071] As described above, the first side fitting portion 125 is fitted to the first side eccentric wheel 1342, and the second side fitting portion 126 is fitted to the second side eccentric wheel 1343, and thus the first massage arm 123 is supported to the rotating shaft 133 via the first side eccentric wheel 1342, and the second massage arm 124 is supported to the rotating shaft 133 via the second side eccentric wheel 1343. In this case, when the rotating shaft 133 is rotated by the motor 131, the first side eccentric wheel 1342 swings the first massage arm 123 back and forth, and the second side eccentric wheel 1343 swings the second massage arm 124 back and forth.

[0072] The detection portion 14 detects the positions of the first and second massage arms 123 and 124, and is configured to include a photosensitive code disk 142 that rotates in synchronization with the rotating shaft 133 and has a light passing hole 141, and a photoelectric sensing device 143 that receives light that has passed through the light passing hole 141.

[0073] The control portion can be installed on the massage machine described below, or can be installed outside the massage machine. In the case where the control portion is installed outside the massage machine, the control portion controls the positions of the first and second massage arms 123 and 124 by transmitting and receiving signals wirelessly. In the present embodiment, the control portion sets the massage portion 12 to a standby state based on the position signal described below when the first massage unit 1 stops massage.

[0074] Specifically, the inductive encoder 142 of the detection unit 14 rotates in synchronization with the rotation shaft 133, and when the light on the inductive encoder 142 rotates to the position of the photoelectric inductive device 143 through the light passing hole 141, the photoelectric inductive device 143 receives the light passing through the light passing hole 141. The light inductive device 143 is turned on and outputs a position signal indicating that both the first massage arm 123 and the second massage arm 124 are in a specific position below the support surface 112S when receiving the light. The position signal is fed back to the control unit. When the first massage unit 1 stops the massage, the control unit stops the rotation of the rotation shaft 133 by stopping the driving of the driving unit 13 in a manner that the massage unit 12 is set to the standby state when receiving the position signal. Here, the specific position refers to the position of the support surface 112S supporting the hips.

[0075] In the present embodiment, the specific position below which both the first massage arm 123 and the second massage arm 124 are located refers to the specific position at which the upper ends of the first massage arm 123 and the second massage arm 124 are below the support surface 112S as shown in FIG. 4. The specific position above which both the first massage arm 123 and the second massage arm 124 are located refers to the specific position at which the upper ends of the first massage arm 123 and the second massage arm 124 are above the support surface 112S as shown in FIG. 5.

[0076] In addition, as shown in FIGS. 3-5, when the first massage arm 123 is fixed to one end of the first side sleeve 125 and the second massage arm 124 is fixed to one end of the second side sleeve 126, a first limiting portion 127 is formed at the other end of the first side sleeve 125 and a second limiting portion 128 is formed at the other end of the second side sleeve 126. In this way, the first massage member and the second massage member can swing back and forth within a specified range by the first limiting portion and the second limiting portion.

[0077] In the present embodiment, the first limiting portion 127 and the second limiting portion 128 are universal joints fixed to the core frame 111. In this case, the first massage arm 123 and the second massage arm 124 are installed to the core frame 111 via the universal joints, so that the universal joints can limit the range of the back and forth swinging of the first massage arm 123 and the second massage arm 124.

[0078] In the present embodiment, the detection unit detects the positions of the first massage arm and the second massage arm and outputs a position signal indicating that both the first massage arm and the second massage arm are in a specific position below the support surface, and the control unit sets the massage unit to the standby state based on the position signal when the first massage unit stops the massage, so that both the first massage arm and the second massage arm are completely accommodated into the accommodation space after the user stops the massage. Therefore, the user will not feel the foreign body, so that the comfort of the user can be improved.

[0079] Further, in the present embodiment, the first massage unit 1 is described as being used to massage the user's buttocks, but the prescribed part of the user that the first massage unit 1 massages can include at least any one of the thigh, the lower leg, the arm, the neck, the back, and the abdomen.

[0080] (Second Massage Unit)

[0081] Fig. 6 is a perspective view showing the general structure of the second massage unit according to the present application. Fig. 7 is an exploded perspective view showing the general structure of the second massage unit according to the present application. Fig. 8 is a perspective view showing the general structure of the drive section and one tray section of the second massage unit according to the present application. Fig. 9 is a perspective view showing the general structure of the drive section and two tray sections of the second massage unit according to the present application.

[0082] The second massage unit 10 according to the present embodiment is installed, for example, to the seat section of the following massage machine, and is used to massage the user's thigh. The second massage unit 10 according to the present embodiment, as shown in Figs. 6 and 7, has a main body section 101, a massage section 102, a drive section 103, and a restriction section 104.

[0083] The main body section 101 includes a core frame 1011 and a support structure 1012. The support structure 1012 includes a first support body 1012a, a second support body 1012b, a first belt member 1012c supported between the first support body 1012a and the second support body 1012b, a pair of seat cushions 1012d, and a second belt member 1012e supported between the pair of seat cushions 1012d. The structure of the main body section 101 is substantially the same as that of the main body section 11, and thus detailed description of the structure of the main body section 101 is omitted here.

[0084] The massage section 102 includes two massage members 1021. Note that the number of the massage members 1021 is not limited to two, and can be one or more than three.

[0085] The massage member 1021 has a tray section 1022 and an air bag section 1023 fixed to substantially the entire surface 1022S of the tray section 1022. The air bag section 1023 swings in synchronization with the tray section 1022.

[0086] In the present embodiment, the air bag section 1023 covers substantially the entire surface 1022S of the tray section 1022, but is not limited thereto, and the air bag section can cover only a part of the surface of the tray section, or can not be provided on the surface of the tray section.

[0087] Further, in the present embodiment, the tray section 1022 has a lower tray section 1024 and a side tray section 1025 connected to the lower tray section 1024, and thus is formed as an L-shaped tray.

[0088] The air bag portion 1023 has a bottom air bag portion 1026 and a side air bag portion 102. The bottom air bag portion 1026 is fixed to the lower tray portion 1024, and the side air bag portion 102 is fixed to the side tray portion 1025. In addition, the bottom air bag portion 1026 and the side air bag portion 102 can be connected to each other to be charged and discharged, or can be separately charged and discharged.

[0089] In addition, the bottom air bag portion 1026 and the side air bag portion 102 can be provided separately or integrally. In the case where the bottom air bag portion 1026 and the side air bag portion 102 are provided integrally, by providing the side air bag portion and the bottom air bag portion integrally in the same L-shaped tray portion, it is possible to more reliably wrap and pinch the thigh portion to perform kneading. In the case where the bottom air bag portion 1026 and the side air bag portion 102 are provided separately, by providing the side air bag portion and the bottom air bag portion separately in the same L-shaped tray portion, it is possible to provide a variety of massage methods.

[0090] In the present embodiment, the air bag portion 1023 has two air bag portions, the bottom air bag portion 1026 and the side air bag portion 102. However, it is not limited thereto, and the air bag portion can have one or more than three air bag portions. In the case where the air bag portion has a plurality of air bag portions, the plurality of air bag portions can be connected to each other to be charged and discharged, or can be separately charged and discharged.

[0091] The drive portion 103 drives the massage portion 102 to reciprocally swing the massage portion 102 in the support surface direction and the up-down direction. That is, the massage portion 102 is reciprocally swung not only in the up-down direction but also in each direction in which the support surface on which the massage portion 102 is present is present (for example, each of the front-rear direction and the left-right direction).

[0092] As shown in FIG. 7, the drive portion 103 includes a motor 1031, a worm 1032 as a power transmission mechanism, a rotation shaft 1033, and two eccentric mechanisms 1034. The motor 1031 is mounted to the core frame 1011 and includes an output shaft.

[0093] The worm 1032 functions as a mechanism that transmits the driving force of the motor 1031 to the rotation shaft 1033 to rotate the rotation shaft 1033. The worm 1032 is fixed to the substantially center of the rotation shaft 1033 via a bearing 1035. The worm 1032 is connected to the output shaft of the motor 1031, so that the worm 1032 receives the driving force of the motor 1031 to rotate and rotate the rotation shaft 1033.

[0094] In addition, the worm 1032 can be housed in a case composed of a first case 1036 on the upper side and a second case 1037 on the lower side.

[0095] The rotating shaft 1033 is rotatably supported between the two side walls of the core frame 1011 via a shaft sleeve 1038 and a shaft collar 1039.

[0096] The two eccentric mechanisms 1034 are fixed to the driving shaft 1033 and are located on both sides of the turbine 1032. The eccentric mechanisms 1034 function as mechanisms that rotate in synchronization with the driving shaft 1033 to drive the massage portion 102 to swing back and forth in the direction of the support surface and the up-and-down direction of the massage portion. The eccentric mechanisms 1034 are fixed to the driving shaft 1033 in a manner to be rotationally driven by the driving shaft 1033 and are located on the lower side of the massage portion 102. The massage portion 102 is connected to the eccentric mechanisms 1034 in a manner to be swung by the eccentric mechanisms 1034.

[0097] In the present embodiment, the eccentric mechanism 1034 is configured to have an inclined eccentric 1034a and an outer fitting portion 1034b fitted to the inclined eccentric 1034a. The inclined eccentric 1034a has an eccentric portion and an inclined portion inclined toward the inner side, and the outer fitting portion 1034b is fitted to the outer side of the inclined portion. The outer fitting portion 1034b rotates in synchronization with the inclined portion inclined toward the inner side. That is, as shown in FIG. 8, the outer fitting portion 1034b (inclined portion) is inclined in such a manner that the distance Ll from the center axis of the turbine 1032 at the upper end 10341 thereof is smaller than the distance L2 from the center axis of the turbine 1032 at the lower end 10342 thereof.

[0098] In addition, as shown in FIG. 9, the outer fitting portion 1034b is mounted to the inclined eccentric 1034a via an inner connecting member 1034c. The outer fitting portion 1034b and the inner connecting member 1034c can be a bearing assembly. The outer fitting portion 1034b is connected to the tray portion 1022, so that the tray portion 1022 is swung by the outer fitting portion 1034b of the inclined portion.

[0099] The limiting portion 104 limits the swinging of the massage portion 102. Specifically, the limiting portion 104 is configured to include a double-headed universal joint 1041, and the two spherical ends of the double-headed universal joint 1041 are respectively accommodated in spherical head covers 1043 formed by upper and lower housings 1042. One of the two spherical head covers 1043 is fixed to the tray portion 1022, and the other spherical head cover 1043 is fixed to the core frame 1011. During swinging of the tray portion 1022 by the outer fitting portion 1034b, the double-headed universal joint 1041 also swings in synchronization. Since the double-headed universal joint 1041 is accommodated in the spherical head covers 1043, the swinging of the double-headed universal joint 1041 is limited by the spherical head covers 1043, so that the double-headed universal joint 1041 can limit the swinging range of the tray portion 1022.
