Description

Technical Field

[0001] This invention relates to the field of massage devices, and more particularly to a massage machine having the function of applying treatment to the shoulder of the recipient. Background Technology

[0002] Patent document JP2001-112826A discloses a massage chair with a backrest and a hand-shaped treatment element provided on the upper part of the backrest for treating the shoulders of the person being treated.

[0003] However, in the case of the massage chair mentioned above, the hand-shaped treatment piece can easily obstruct the patient's movement when they get up after the treatment. Summary of the Invention

[0004] The present invention was made in view of the above-mentioned problems, and its purpose is to provide a massage machine that makes it easier for the person receiving the massage to get up.

[0005] To achieve the above objectives, the present invention provides a massage machine having a frame and a shoulder treatment mechanism, wherein the shoulder treatment mechanism includes: a fixing part connected and fixed to the frame; a moving part having a treatment element supported on the frame via the fixing part and movable relative to the fixing part in the shoulder width direction; and a force-applying part driving the moving part to reciprocate.

[0006] According to the massage machine of the present invention, when the patient gets up after the treatment, the moving part is moved outward in the shoulder width direction by using the force-applying part, which can suppress the interference between the moving part with the treatment element and the patient's shoulder, making it easier for the patient to get up.

[0007] Furthermore, in the massager of the present invention, it is preferable that the force-applying part has a telescopic member that allows the moving part to reciprocate by extending and retracting.

[0008] Furthermore, in the massager of the present invention, the telescopic component preferably includes an elastic component, which is disposed between the fixed part and the movable part and applies force to the movable part toward the outer side in the shoulder width direction.

[0009] According to the massager of the present invention, in non-working states such as when the massage ends or the power is disconnected, the moving part can naturally return to the outer side in the shoulder width direction, which facilitates the user to get up and also easily achieves energy saving.

[0010] Furthermore, in the massager of the present invention, the telescopic component preferably includes an airbag, which is disposed between the fixed part and the movable part, and applies force to the movable part toward the inside in the shoulder width direction when inflated.

[0011] According to the massager of the present invention, in non-working states such as when the massager has finished massaging or when the power is disconnected, the moving part is helped to return to the outer side in the shoulder width direction, which facilitates the patient to get up and also easily achieves energy saving.

[0012] Furthermore, in the massager of the present invention, the fixed part preferably has a guide rail that extends along the shoulder width direction, and the movable part has a slider that engages with the guide rail in a manner that allows it to slide relative to the guide rail.

[0013] Furthermore, in the massager of the present invention, the slider preferably has: an upper abutting portion that abuts against the guide rail from above; and a lower abutting portion that abuts against the guide rail from below.

[0014] According to the massager of the present invention, even if the massager is subjected to a reaction force from the shoulder of the person being massaged during the massage process, the up-down position of the moving part can be easily maintained, ensuring that the massage can be performed according to the settings.

[0015] Furthermore, in the massager of the present invention, it is preferable to provide a movement limiting part between the moving part and the fixed part.

[0016] According to the massager of the present invention, a movement limiting part is provided between the moving part and the fixed part, and the movement limiting part regulates the range of movement of the moving part relative to the fixed part. The movement limiting part restricts the range of movement of the moving part in the shoulder width direction, thereby suppressing excessive movement of the moving part toward the inward side in the shoulder width direction. The movement limiting part restricts the movement of the moving part in the front-back direction, further ensuring that the moving part moves only in the shoulder width direction relative to the fixed part, without any offset in the front-back direction.

[0017] Furthermore, in the massager of the present invention, the shoulder treatment mechanism preferably includes a detection unit that detects the movement of the moving part.

[0018] Furthermore, in the massager of the present invention, the shoulder treatment mechanism preferably includes a control unit, which controls the movement of the force application unit based on the detection result of the detection unit.

[0019] According to the massager of the present invention, the shoulder treatment mechanism includes a control unit, which controls the movement of the force application unit based on the detection result of the detection unit, thereby enabling precise control of the movement of the moving part.

[0020] Furthermore, in the massager of the present invention, the treatment member preferably has: a rotating shaft extending in a direction intersecting the shoulder width direction; and a pair of treatment arms supported on the rotating shaft in a manner that allows eccentric rotation relative to the rotating shaft, each having a pin portion; the moving part having a support body supporting the treatment member and having a guide groove into which the pin portion is inserted to restrict the movement trajectory of the treatment arm.

[0021] According to the massage machine of the present invention, the shoulder treatment mechanism includes: a fixed part connected and fixed to the frame; a movable part having a treatment element, supported on the frame via the fixed part, and movable relative to the fixed part in the shoulder width direction; and a force-applying part driving the movable part to reciprocate. Therefore, when the patient gets up after treatment, by using the force-applying part to move the movable part outward in the shoulder width direction, interference between the movable part having the treatment element and the patient's shoulder can be suppressed, making it easier for the patient to get up.

[0109] Below, in conjunction with Figures 1 to 11 The massage machine according to an embodiment of the present invention will be described.

[0110] For ease of explanation, the orientation of the massage machine's structure is described based on the perspective of the person receiving the massage while seated. For example, the front side (front view) is referred to as "front" or "forefront," the back side (back view) as "back" or "rear," the upper side (head side) as "upper" or "above," the lower side (foot side) as "lower" or "below," the right side as "right" or "right-hand side," and the left side as "left" or "left-hand side." Furthermore, the shoulder-width direction of the person receiving the massage is simply referred to as "shoulder-width direction," which is the left-right direction of the massage machine. "Outer side of the shoulder-width direction" corresponds to the direction away from the person's neck in the shoulder-width direction, and "inner side of the shoulder-width direction" corresponds to the direction closer to the person's neck in the shoulder-width direction.

[0111] —Overall Structure of the Massager—

[0112] like Figures 1 to 4B As shown, the massage machine A has a frame J and a shoulder treatment mechanism S. The shoulder treatment mechanism S includes a fixed part S1, a movable part S2, and a force-applying part S3. The fixed part S1 is connected and fixed to the frame J. The movable part S2 has a treatment element 1, which is supported on the frame J via the fixed part S1 and can move relative to the fixed part S1 in the shoulder width direction. The force-applying part S3 drives the movable part S2 to reciprocate.

[0113] Here, as Figure 1 and Figure 2 As shown, massage machine A is a massage chair. The frame J includes a seat J1 and a backrest J2. The seat J1 is for the user to sit in. The backrest J2 is rotatably connected to the seat J1 and is used for the user's back to lean against. A shoulder treatment mechanism S is provided on the upper part of the backrest J2. A left shoulder treatment mechanism S and a right shoulder treatment mechanism S are respectively provided on the left and right sides of the backrest J2. The shoulder treatment mechanisms S are arranged in pairs on the left and right sides in the shoulder width direction, with their respective treatment components 1 being closer to each other than their respective fixing parts S1. That is, the treatment components 1 of the left and right shoulder treatment mechanisms S are both located inside the left and right direction than the fixing parts S1.

[0114] —Structure of a shoulder treatment facility—

[0115] As described above, the shoulder treatment mechanism S includes a fixed part S1, a movable part S2, and a force-applying part S3.

[0116] Here, as Figure 4A , Figure 4B and Figure 5 As shown, the shoulder treatment mechanism S includes a detection unit S4, which detects the position of the moving part S2 relative to the fixed part S1.

[0117] In addition, although not shown in the figure, the shoulder treatment mechanism S also includes a control unit, which controls the movement of the force application unit S3 based on the detection results of the detection unit S4.

[0118] 1) Specific structure of the fixing part

[0119] In this embodiment, the fixing part S1 is fixed to the frame J.

[0120] Here, as Figures 3 to 5 As shown, the fixing part S1 includes a base 91 and a connecting arm 92. The base 91 holds the moving part S2. The connecting arm 92 connects and fixes the base 91 to the frame J.

[0121] In addition, such as Figures 3 to 5 As shown, the base 91 includes a base plate 911 and a side plate 912. The thickness direction of the base plate 911 is consistent with the vertical direction. The base plate 911 supports the moving part S2 from below. A guide rail 913 is provided on the base plate 911, which extends in the shoulder width direction. A groove 9131 is recessed downward relative to the guide surface of the guide rail 913 at the center of the width direction (front-back direction). This groove 9131 extends in the shoulder width direction and provides space for the following protrusion 24 of the moving part S2 (see reference). Figure 4A , Figure 4B (A portion of the protrusion 24 is shown in dashed lines) is inserted. In the shoulder width direction, the length of the groove 9131 is less than the length of the guide rail 913. The protrusion 24 moves within the length range of the groove 9131 in the shoulder width direction. A mounting portion 914 is also provided on the base plate 911 for mounting components of the detection unit S4. In this embodiment, a pair of guide rails 913 are provided at intervals in the front-rear direction. Side plates 912 rise upwards from the outer end of the base plate 911 in the shoulder width direction. The thickness direction of the side plates 912 is aligned with the shoulder width direction. The base 91 also includes a pair of reinforcing plates 915, which rise upwards from both ends of the base plate 911 in the front-rear direction. The thickness direction of the reinforcing plates 915 is aligned with the front-rear direction. The side plates 912 protrude upwards more than the reinforcing plates 915.

[0122] In addition, such as Figures 3 to 5 As shown, the connecting arm 92 includes a base plate 921. The base plate 921 is an elongated strip extending in the front-to-back direction. The thickness direction of the base plate 921 is consistent with the shoulder width direction. Multiple holes are provided on the base plate 921 for connection and fixation with the frame J, the side plate 912 of the base 91, the force application part S3, etc. The connecting arm 92 also includes a pair of reinforcing plates 922, which stand upright from both ends of the base plate 921 in the vertical direction towards the same side in the shoulder width direction, and towards the side plate 912 of the base 91. The thickness direction of the reinforcing plates 922 is consistent with the vertical direction. The connecting arm 92 protrudes further rearward than the side plate 912 of the base 91.

[0123] 2) Specific structure of the moving part

[0124] As described above, the moving part S2 has a treatment component 1.

[0125] Here, the moving part S2 can move along the shoulder width direction, thereby moving between a retracted position and an extended position that is closer to the patient's neck in the shoulder width direction than the retracted position. In this embodiment, the retracted position and the extended position are arranged in the left-right direction, and are the same in the up-down direction relative to the massage machine. When the moving parts S2 of both the left and right shoulder treatment mechanisms S are in the retracted position, the distance between the left and right treatment members 1 is K1. When the moving parts S2 of both the left and right shoulder treatment mechanisms S are in the extended position, the distance between the left and right treatment members 1 is K2. Distance K1 is greater than distance K2. When distance K1 is greater than the width of the back support for the patient's back, it helps the patient to sit comfortably.

[0126] In addition, such as Figure 5 As shown, the treatment device 1 has: a rotation shaft 11 extending in a direction intersecting the shoulder width direction (in the illustrated example, the front-back direction); and a pair of treatment arms 12 supported on the rotation shaft 11 in a manner that allows eccentric rotation relative to the rotation shaft 11, and each having pins 1212A and 1212B.

[0127] In addition, such as Figures 3 to 5 As shown, the moving part S2 also has a support body 2, which supports the treatment member 1. The support body 2 has a slider 23, which engages with the guide rail 913 in a manner that allows it to slide relative to the guide rail 913. The support body 2 also has a guide groove 2221 into which pins 1212A and 1212B are inserted to restrict the movement trajectory of the treatment arm 20.

[0128] In this embodiment, such as Figures 3 to 5As shown, the support body 2 has a support plate 21, a first cover 22, and a second cover 25. The thickness direction of the support plate 21 is consistent with the vertical direction. The first cover 22 is disposed above the support plate 21, and the support plate 21 protrudes inward in the shoulder width direction from the first cover 22. The first cover 22 has two protruding portions 221 that protrude from the bottom plate 22 on both sides in the front-rear direction. Each protruding portion 221 has a guide groove 2221 that extends in the front-rear direction, faces one side in the shoulder width direction, and opens to the side of the treatment piece 1. A slider 23 is fixed below the protruding portions 221 of the first cover 22. The slider 23 has an upper abutment portion 231 that abuts against the guide rail 913 from the upper side; and a lower abutment portion 232 that abuts against the guide rail 913 from the lower side. The slider 23 also has a connecting portion 233 that connects the upper abutment portion 231 and the lower abutment portion 232. In the illustrated example, a pair of lower abutment portions 232 are spaced apart in the front-to-back direction, and the slider 23 is generally formed in a C-shape with an opening facing downwards. The slider 23 has a protrusion 24 that inserts into the groove 9131 of the guide rail 913. The protrusion 24 is, for example, made of screw, and extends through the support plate 21 near the rear end in the vertical direction. The second cover 25 covers the treatment piece 1 from above and from both sides in the front-to-back direction, and can be attached to and detached from the first cover 22.

[0129] A pair of sliders 23 are spaced apart in the front-to-back direction. Each pair of sliders 23 corresponds to a pair of guide rails 913. The guide rails 913 are inserted into the hollow space formed by the upper abutment portion 231 and the lower abutment portion 232 of the sliders 23 in the left-to-right direction. Thus, the guide rails and the upper and lower abutment portions slidably abut against each other, forming a sliding abutment structure. During the movement of the sliders 23 along the guide rails 913, the upper and lower abutment portions 231 and 232 restrict the sliders 23 from disengaging in the vertical direction.

[0130] A movement limiting part is provided between the slider 23 of the moving part S2 and the guide rail 913 of the fixed part S1. The movement limiting part restricts the range of movement of the slider 23 in the shoulder width direction. The movement limiting part includes the aforementioned protrusion 24 provided on the slider 23 and the aforementioned groove 9131 provided on the guide rail 913. The groove 9131 extends in the shoulder width direction, and the protrusion 24 is correspondingly provided in the groove 9131, inserted into the groove 9131, and moves within the range of the groove 9131. The protrusion 24 can only move along the shoulder width direction within the length range of the groove 9131, thereby limiting the range of movement of the protrusion 24 in the shoulder width direction. Therefore, excessive movement of the moving part S2 toward the inward side in the shoulder width direction can be suppressed. The movement of the protrusion 24 within the width range of the groove 9131 is restricted, which further ensures that the slider 23 slides only along the guide rail 913 without any offset in the front-back direction.

[0131] The sliding contact structure between the guide rail 913 and the slider 23 cooperates with the movement restriction part to ensure that the shoulder treatment mechanism S does not deviate in the left and right directions, and also to ensure that the shoulder treatment mechanism S can perform stable treatment actions even when it moves left and right while treating the shoulder (i.e., it is subjected to vertical force).

[0132] The following is a more detailed description of the treatment component 1 and the guide groove 2221 that mates with it.

[0133] As described above, the treatment device 1 includes a rotating shaft 11 and a pair of treatment arms 12.

[0134] Here, as Figure 5 As shown, the treatment device 1 also includes a drive mechanism 13 and a retainer 14. The drive mechanism 13 drives the rotating shaft 11 to rotate. The retainer 14 is fixed to the support body 2 and supports the rotating shaft 11 and the drive mechanism 13.

[0135] In addition, such as Figure 5 and Figure 7 As shown, the rotating shaft 11 extends in the front-to-back direction and is rotatably supported on the retaining seat 14 via a first bearing 151A and a second bearing 152A arranged at intervals in the front-to-back direction.

[0136] In addition, such as Figure 5 As shown, the paired treatment arms 12 include a first treatment arm 12A and a second treatment arm 12B. The first treatment arm 12A and the second treatment arm 12B are spaced apart and rotatably mounted on the rotation axis 11. The first treatment arm 12A and the second treatment arm 12B are respectively eccentric and inclined relative to the rotation axis 11 (that is, the rotation center of the first treatment arm 12A and the second treatment arm 12B is not the same as the rotation center of the rotation axis 11, and the extension direction of the main body of the first treatment arm 12A and the second treatment arm 12B is inclined relative to the extension direction of the rotation axis 11).

[0137] In addition, such as Figure 5 and Figure 9 As shown, the first treatment arm 12A has: a first body 121A, which has a first massage portion 1211A; and a first pin portion 1212A, which is fixed relative to the first body 121A. Figure 5 and Figure 11As shown, the second treatment arm 12B has: a second body 121B, which has a second massage portion 1211B; and a second pin 1212B, which is fixed relative to the second body 121B. The first massage portion 1211A and the second massage portion 1211B are spaced apart and face each other, respectively massaging the shoulders of the recipient. The first pin 1212A and the second pin 1212B are respectively inserted into a pair of guide grooves 2221 of the support body 2, thereby restricting the rotation of the first treatment arm 12A and the second treatment arm 12B with the rotation of the rotation shaft 11. Specifically, the pair of guide grooves 2221 of the support body 2 restrict the movement of the first pin 1212A and the second pin 1212B in the circumferential direction of the rotation shaft 11, but allow the first pin 1212A and the second pin 1212B to move in the radial direction of the rotation shaft 11 and in the extension direction of the rotation shaft 11.

[0138] (First treatment arm and its supporting structure)

[0139] As described above, the first treatment arm 12A has: a first body 121A, which is provided with a first massage portion 1211A; and a first pin portion 1212A, which is fixed relative to the first body 121A.

[0140] Here, as Figures 5 to 7 , Figure 9 As shown, the first body 121A has a first extension, namely a first plate-shaped portion 1219A, extending in a direction intersecting the rotation axis 11. A protrusion 1218A is formed at the end of the first plate-shaped portion 1219A opposite to the guide groove 2221, protruding toward the second treatment arm 12B. In the illustrated example, the protrusion 1218A is formed as a columnar shape folded back from the end of the first plate-shaped portion 1219A opposite to the guide groove 2221 toward the rotation axis 11, but it is not limited to this. A first massage portion 1211A is provided at the front end of the protrusion 1218A.

[0141] In addition, such as Figure 9 and Figure 10 As shown, the first massage part 1211A is detachably mounted on the first body 121A (in the illustrated example, it is fitted onto the front end of the protrusion 1218A, but is not limited thereto). The portion of the first massage part 1211A that contacts the treated area is spherical. Furthermore, as... Figure 6 As shown, the motion trajectory T1 of the first massage part 1211A is, for example, formed as a closed shape with a span in the extension direction of the rotation axis 11 greater than the span in the radial direction of the rotation axis 11.

[0142] In addition, such as Figure 9 and Figure 10As shown, the first pin 1212A is integrally formed with the first body 121A. The first pin 1212A protrudes from the first body 121A in a direction away from the first massage portion 1211A. Furthermore, as... Figure 5 As shown, the first pin 1212A is a cylindrical protrusion that protrudes from the first body 121A toward the guide groove 2221.

[0143] In addition, such as Figures 5 to 8 As shown, the first treatment arm 12A is eccentrically and obliquely supported on the rotation shaft 11 via a first cam member 16A. The first cam member 16A is sleeved on the rotation shaft 11 in an eccentric manner relative to the rotation shaft 11. The first cam member 16A includes a first cylindrical portion 161A and a first cover portion 162A sleeved on the rotation shaft 11. A first cam groove GV1 is formed by the first cylindrical portion 161A and the first cover portion 162A. The first cylindrical portion 161A is fixed to the rotation shaft 11 and has a first large-diameter portion P11 and a first small-diameter portion P12 with an outer diameter smaller than the first large-diameter portion P11, arranged along the extending direction of the rotation shaft 11. The first cover portion 162A has an outer diameter larger than the first small-diameter portion P12. The first cover portion 162A is assembled to the first cylindrical portion 161A from the side opposite to the first large-diameter portion P11 relative to the first small-diameter portion P12. The end face of the first large-diameter portion P11 located on the side of the first small-diameter portion P12 is not orthogonal to the extending direction of the rotation axis 11, and the angle A formed by the two is less than 90 degrees. Similarly, the angle B formed by the end face of the first cover portion 162A located on the side of the first small-diameter portion P12 and the extending direction of the rotation axis 11 is also less than 90 degrees. In this embodiment, angles A and B are the same. That is, the end face of the first large-diameter portion P11 located on the side of the first small-diameter portion P12 and the end face of the first cover portion 162A located on the side of the first small-diameter portion P12 are opposite to each other and parallel to each other, and both have the same tilt angle relative to the rotation axis 11. The end face of the first large-diameter portion P11 located on the side of the first small-diameter portion P12 and the end face of the first cover portion 162A located on the side of the first small-diameter portion P12 constitute the sidewall surface of the first cam groove GV1, constituting the extending direction of the first cam groove GV1. With the first cylindrical portion 161A mounted on the rotating shaft 11, the outer peripheral surface of the first minor diameter portion P12 is inclined relative to the rotating shaft 11 at an angle of C. The outer peripheral surface of the first minor diameter portion P12 forms the bottom surface of the first cam groove GV1. As a result, the first cam groove GV1 is eccentric relative to the rotating shaft 11, and both its extension direction and bottom surface are inclined relative to the rotating shaft 11.

[0144] In addition, such as Figure 5 , Figure 9 and Figure 10As shown, the first body 121A of the first treatment arm 12A has a first through hole TH1 through which the first small diameter portion P12 of the first cylindrical portion 161A passes and whose shape matches the first cam groove GV1. The first treatment arm 12A is sleeved in the first cam groove GV1 through its first through hole TH1. The first cylindrical portion 161A (specifically the first large diameter portion P11) and the first cover portion 162A define the two ends of the first small diameter portion P12 from both sides of the extension direction of the rotation shaft 11, thereby forming the first cam groove GV1.

[0145] (Second treatment arm and its supporting structure)

[0146] As described above, the second treatment arm 12B includes: a second body 121B having a second massage portion 1211B; and a second pin portion 1212B fixed relative to the second body 121B.

[0147] Here, as Figures 5 to 7 , Figure 11 As shown, the second body 121B has a second extension, namely a second plate-shaped portion 1219B, extending in a direction intersecting the rotation axis 11. A second massage portion 1211B is provided at the end of the second plate-shaped portion 1219B opposite to the guide groove 2221. The radial dimension of the second body 121B on the rotation axis 11 is larger than the radial dimension of the first body 121A on the rotation axis 11.

[0148] In addition, such as Figure 11 As shown, the second massage portion 1211B is integrally formed with the second main body 121B. Similar to the first massage portion 1211A, the portion of the second massage portion 1211B that contacts the treated area is spherical. However, the shape of the second massage portion 1211B differs from the shape of the first massage portion 1211A. Figure 6 As shown, similar to the first massage unit 1211A, the movement trajectory T2 of the second massage unit 1211B is, for example, formed as a closed shape with a span in the extending direction of the rotation axis 11 greater than the span in the radial direction of the rotation axis 11. However, the movement trajectory T2 of the second massage unit 1211B is different from the movement trajectory T1 of the first massage unit 1211A. Furthermore, multiple second massage units 1211B are arranged along the extending direction of the second plate-shaped portion 1219B.

[0149] In addition, such as Figure 11 As shown, the second pin 1212B is integrally formed with the second body 121B. The second pin 1212B protrudes from the second body 121B in a direction away from the second massage portion 1211B. Furthermore, as... Figure 5 As shown, the second pin 1212B is a protrusion that extends from the second body 121B toward the guide groove 2221.

[0150] In addition, such as Figures 5 to 8 As shown, the second treatment arm 12B is eccentrically and obliquely supported on the rotation axis 11 relative to the rotation axis 11 via the second cam member 16B (in Figure 6 In the current state, the first treatment arm 12A and the second treatment arm 12B are generally formed in a V-shape. The second cam component 16B includes a second cylindrical portion 161B and a second cover portion 162B sleeved on the rotating shaft 11. The second cylindrical portion 161B is fixed to the rotating shaft 11 and has a second large-diameter portion P21 and a second small-diameter portion P22 with an outer diameter smaller than that of the second large-diameter portion P21, arranged along the extending direction of the rotating shaft 11. The second cover portion 162B has an outer diameter larger than that of the second small-diameter portion P22. The second cover portion 162B is assembled to the second cylindrical portion 161B from the side opposite to the second large-diameter portion P21 relative to the second small-diameter portion P22. The end face of the second large-diameter portion P21 located on the side of the second small-diameter portion P22 is not orthogonal to the extending direction of the rotating shaft 11, and the angle D formed by the two is less than 90 degrees. The angle E formed by the end face of the second cover portion 162B located on the side of the second small-diameter portion P22 and the extending direction of the rotating shaft 11 is also less than 90 degrees. In this embodiment, angle D is the same as angle E (in the illustrated example, angle D is the same as angle A). That is, the end face of the second large diameter portion P21 located on the side of the second small diameter portion P22 and the end face of the second cover portion 162B located on the side of the second small diameter portion P22 are opposite to each other and parallel to each other, and both have the same tilt angle relative to the rotation axis 11. The end face of the second large diameter portion P21 located on the side of the second small diameter portion P22 and the end face of the second cover portion 162B located on the side of the second small diameter portion P22 constitute the sidewall surface of the second cam groove GV2, constituting the extension direction of the second cam groove GV2. When the second cylinder portion 161B is mounted on the rotation axis 11, the outer peripheral surface of the second small diameter portion P22 is inclined relative to the rotation axis 11, and the tilt angle is F (in the illustrated example, angle F is the same as angle C). The outer peripheral surface of the second small diameter portion P22 constitutes the bottom surface of the second cam groove GV2. Therefore, the second cam groove GV2 is eccentric relative to the rotation axis 11, and its extension direction and bottom surface are both inclined relative to the rotation axis 11.

[0151] In addition, such as Figure 5 and Figure 11 As shown, the second body 121B of the second treatment arm 12B has a second through hole TH2 through which the first small diameter portion P22 of the second cylindrical portion 161B passes and whose shape matches the second cam groove GV2. The second treatment arm 12B is fitted into the second cam groove GV2 through its second through hole TH2. The second cylindrical portion 161B (specifically the second large diameter portion P21) and the second cover portion 162B define the two ends of the second small diameter portion P22 from both sides of the extension direction of the rotation shaft 11, thereby forming the second cam groove GV2.

[0152] (Structure of the guide groove)

[0153] As described above, the guide groove 2221 restricts the first treatment arm 12A and the second treatment arm 12B from rotating irregularly with the rotation shaft 11.

[0154] Here, as Figure 5 As shown, the guide groove 2221 includes a first guide groove 2221A and a second guide groove 2221B. The first guide groove 2221A is for the insertion of the first pin 1212A, and the second guide groove 2221B is for the insertion of the second pin 1212B. When the rotating shaft 11 rotates, the tips of the first pin 1212A and the second pin 1212B move in an arc shape within the first guide groove 2221A and the second guide groove 2221B.

[0155] In addition, such as Figure 5 As shown, the first guide groove 2221A and the second guide groove 2221B are located on both sides of the retaining seat 14 in the extension direction of the rotating shaft 11.

[0156] Here, taking the first guide groove 2221A as an example, the structure of the guide groove is explained, and the cooperative effect between the guide groove and the pin is illustrated. For example... Figure 5 As shown, the first guide groove 2221A extends parallel to the rotation shaft 11, that is, the length direction of the first guide groove 2221A is consistent with the extension direction of the rotation shaft 11. The first pin 1212A can slide along the length direction of the first guide groove 2221A. The width direction of the first guide groove 2221A intersects the extension direction of the rotation shaft 11, and is orthogonal in this embodiment. The width dimension of the first guide groove 2221A is approximately the same as the dimension of the first pin 1212A in this direction. The first pin 1212A can slide along the length direction of the first guide groove 2221A, but cannot slide in the width direction of the first guide groove 2221A. In this embodiment, since the width direction of the first guide groove 2221A is orthogonal to the extension direction of the rotation shaft 11, that is, it is located in the circumferential direction of the rotation shaft 11, the movement of the first pin 1212A in the circumferential direction of the rotation shaft 11 can be regulated. When the first treatment arm 12A rotates with the rotating shaft 11 via the eccentric cam structure, it does not produce circumferential upward movement of the rotating shaft 11. At this time, the first pin 1212A presses... Figure 6 The arc-shaped motion trajectory T3 is shown.

[0157] In addition, such as Figure 5As shown, the depth direction of the first guide groove 2221A is in the radial direction of the rotation shaft 11. The first pin 1212A is inserted into the first guide groove 2221A. The first guide groove 2221A restricts the movement of the first pin 1212A in the groove width direction, but allows the first pin 1212A to move in the groove length direction and groove depth direction. The depth of the first guide groove 2221A in the groove depth direction is greater than the distance the first pin 1212A moves radially along the rotation shaft 11 as the rotation shaft 11 rotates. In this embodiment, the first guide groove 2221A is a through groove, thereby eliminating the need to excessively consider the dimensional relationship between the groove depth and the first pin 1212A, and increasing the degree of freedom during assembly.

[0158] (Structure of the drive mechanism)

[0159] like Figure 5 , Figure 7 and Figure 8 As shown, the drive mechanism 13 includes a motor 131 and a transmission mechanism 132.

[0160] Here, as Figure 5 As shown, the motor 131 is disposed between the first treatment arm 12A and the second treatment arm 12B in the extending direction of the rotation shaft 11, and extends perpendicularly to the rotation shaft 11. The motor 131 has a motor housing 1311 connected to the retainer 14 and a drive shaft 1312 supported by the motor housing 1311 for rotation, the drive shaft 1312 extending perpendicularly to the rotation shaft 11.

[0161] In addition, such as Figure 7 and Figure 8 As shown, the transmission mechanism 132 transmits the driving force of the motor 131 to the rotating shaft 11, causing the rotating shaft 11 to rotate. The transmission mechanism 132 includes a turbine 1321. The turbine 1321 is mounted in the middle of the rotating shaft 11 (in the illustrated example, the portion located between the first bearing 151A and the second bearing 152A), is housed in the retainer 14, and engages with a thread formed on the outer circumferential surface of the drive shaft 1312, thereby transmitting the driving force of the motor 131 to the rotating shaft 11. Furthermore, the first treatment arm 12A and the second treatment arm 12B protrude from the transmission mechanism 132 in a direction away from the guide groove 2221.

[0162] (The structure of the seat)

[0163] As described above, the retainer 14 is fixed to the support 2.

[0164] Here, as Figure 5 As shown, the retainer 14 is fixed to the support body 2 from above. In this embodiment, the retainer 14 is fixed to the portion of the support plate 21 that protrudes inward from the first cover 22 in the shoulder width direction.

[0165] In addition, such as Figure 5 As shown, the retainer 14 is an annular housing extending in the middle of the axis of rotation 11. Furthermore, as... Figure 7 As shown, the retainer 14 supports the rotating shaft 11 so that it can rotate via the first bearing 151A and the second bearing 152A.

[0166] 3) Specific structure of the force-applying part

[0167] In this embodiment, the force-applying part S3 drives the moving part S2 to reciprocate between the retracted position and the extended position in the left-right direction. The force-applying part S3 is located between the connecting arm 92 of the moving part S2 and the fixed part S1. The left and right ends of the force-applying part S3 are respectively connected to the connecting arm 92 of the moving part S2 and the fixed part S1.

[0168] Here, as Figure 5 As shown, the force-applying part S3 has a telescopic member 80 that reciprocates the moving part S2 by telescoping.

[0169] In addition, such as Figure 5 As shown, the telescopic member 80 includes an elastic member 81, which is disposed between the fixed part S1 and the movable part S2, and applies force to the movable part S2 towards the outer side in the shoulder width direction. In this embodiment, the elastic member 81 is a coil spring (a tension coil spring in the illustrated example), one end of which is connected to the support body 2 of the movable part S2, and the other end is connected to the base 91 of the fixed part S1 (a side plate 912 in the illustrated example). A pair of elastic members 81 are provided at intervals in the front-rear direction (in the illustrated example, the elastic members 81 are located between the guide rail 913 and the reinforcing plate 915 in the front-rear direction).

[0170] In addition, such as Figure 5 As shown, the telescopic component 80 includes an airbag 82, which is disposed between the fixed part S1 and the movable part S2 and connected to the fixed part S1. The two ends of the airbag 82 in the front-rear direction are connected to the connecting arms 92 of the fixed part S1. When inflated, the airbag 82 expands inward toward the shoulder width direction, supported by the connecting arms 92 fixed in the left-right direction, exerting force on the movable part S2. In this embodiment, two airbags 82 are arranged in the shoulder width direction. Multiple airbags 82 may also be present. For example, each airbag 82 is fixedly connected to each other in a breathable manner and arranged in the left-right direction. The two ends of the inner airbag 82 in the front-rear direction are connected to the movable part S2, and the two ends of the outer airbag 82 in the front-rear direction are connected to the connecting arms 92 of the fixed part S1. Therefore, even with multiple airbags 82, it is easy to control the inflation direction of the multiple airbags 82 as a whole, ensuring that the multiple airbags 82 push the movable part S2 in the desired left-right direction when inflated.

[0171] 4) Specific structure of the testing department

[0172] As described above, the detection unit S4 detects the position of the moving unit S2 relative to the fixed unit S1.

[0173] Here, as Figure 4A , Figure 4B and Figure 5 As shown, the detection unit S4 includes a detected element 71 and a detection element 72. The detected element 71 is disposed on one of the fixed part S1 and the moving part S2, and the detection element 72 is disposed on the other of the fixed part S1 and the moving part S2. In this embodiment, the detected element 71 is a magnet and is disposed on the base 91 of the fixed part S1 (in the illustrated example, a base plate 911). The detection element 72 is a Hall element (in the illustrated example, disposed on a circuit board) and is disposed on the support 2 of the moving part S2 (in the illustrated example, inside the first cover 22).

[0174] In this embodiment, detection elements 72 are respectively provided at two positions inside the first cover 22. The detection elements 72 at the two positions correspond to the retracted position and the extended position of the moving part S2, respectively, and can detect when the moving part S2 is in the retracted position (see reference). Figure 4A ) or in the extended position (refer to) Figure 4B ).

[0175] —Overview of the massager's operation—

[0176] In this embodiment, when the shoulder treatment mechanism S is in standby mode, for example, before the person being treated sits on the massage machine A, the moving part S2 is in the retracted position relative to the fixed part S1 under the action of the force-applying part S3.

[0177] In the above state, the person receiving treatment sits in massage machine A, and then massage machine A is started.

[0178] At this time, if the shoulder treatment mechanism S is activated, the control unit controls the force application unit S3, and the force application unit S3 applies a force to the moving part S2, causing it to move inward in the left-right direction. As a result, the moving part S2 moves inward relative to the fixed part S1 in the shoulder-width direction. Specifically, in this embodiment, by inflating the airbag 82, the airbag 82 expands, increasing the distance between the moving part S1 and the connecting arm 92, thereby reducing the distance between the left and right treatment components 1 in the left-right direction. That is, the treatment component 1 moves inward along the shoulder width of the person being treated.

[0179] When the moving part S2 moves inward relative to the fixed part S1 in the shoulder-width direction, if the detection part S4 detects that the moving part S2 has reached a preset position, the control part stops the further movement of the moving part S2 by the treatment part S3 (for example, maintaining the pressure inside the airbag 82 at a constant value). Furthermore, as the moving part S2 moves inward from the retracted position along the shoulder-width direction, the protrusion 24 slides along the groove 9131, thereby allowing the movement limiting part to define an upper limit distance for the movement of the moving part S2.

[0180] Then, the control unit activates the motor 131, causing the first massage unit 1211A and the second massage unit 1211B to repeatedly approach and then separate. Specifically, when approaching each other, the first massage unit 1211A and the second massage unit 1211B approach the treated area from both sides, applying a force towards each other from their respective sides, gradually clamping the treated area. When separating after approaching each other, the first massage unit 1211A and the second massage unit 1211B move from their closest position in the opposite direction. This repeated approaching and separating motion provides a massage.

[0181] After the treatment is completed, the control unit controls the force application unit S3 (specifically by deflating the airbag 82), thereby causing the moving unit S2 to move outward relative to the fixed unit S1 in the shoulder-width direction.

[0182] According to the massage machine A of this embodiment, the shoulder treatment mechanism S includes: a fixed part S1, which is connected and fixed to the frame J; a moving part S2, which has a treatment element 1, is supported on the frame J via the fixed part S2, and can move relative to the fixed part S2 in the shoulder width direction; and a force-applying part S3, which drives the moving part S2 to reciprocate. Therefore, when the patient gets up after the treatment, by using the force-applying part S3 to move the moving part S2 outward in the shoulder width direction, interference between the moving part S2 with the treatment element 1 and the patient's shoulder can be suppressed, making it easier for the patient to get up.

[0183] Furthermore, according to the massage machine A of this embodiment, in the shoulder treatment mechanism S, the first treatment arm 12A includes: a first body 121A provided with a first massage portion 1211A; and a first pin 1212A fixed relative to the first body 121A. A guide groove 2221 cooperates with the first pin 1212A, thereby restricting the first pin 1212A from moving in the circumferential direction of the rotation axis 11, but allowing the first pin 1212A to move in the radial direction and the extending direction of the rotation axis 11. The second treatment arm 12B includes: a second body 121B provided with a second massage portion 1211B; and a second pin 1212B fixed relative to the second body 121B. A guide groove 2221 cooperates with the second pin 1212B, thereby restricting the second pin 1212B from moving in the circumferential direction of the rotation axis 11, but allowing the second pin 1212B to move in the radial direction and the extending direction of the rotation axis 11. Therefore, it helps to simplify the overall structure and reduce manufacturing costs.

[0188] Furthermore, in the above embodiment, the telescopic member 80 includes an elastic member 81 and an airbag 82, but is not limited to this, and a cylinder or the like may be used instead of the elastic member 81 and the airbag 82.

[0189] Furthermore, in the above embodiment, the force-applying part S3 has a telescopic member 80 that reciprocates the moving part S2 by telescoping, but it is not limited to this. The force-applying part S3 may also have a stepper motor or the like instead of the telescopic member 80.

[0190] Furthermore, in the above embodiment, the eccentricity of the first treatment arm 12A relative to the rotation axis 11 is the same as that of the second treatment arm 12B relative to the rotation axis 11, but it is not limited to this.

However, it is not limited to this. It is also possible to set angle A and angle D to be different, that is, to set the tilt amount of the first treatment arm 12A relative to the rotation axis 11 to be different from the tilt amount of the second treatment arm 12B relative to the rotation axis 11.

[0192] Furthermore, in the above embodiments, the massage portion of the first treatment arm 12A and the massage portion of the second treatment arm 12B that contacts the treated portion are respectively spherical, but are not limited to this and can be appropriately modified as needed.

[0194] Furthermore, in the above embodiments, the movement trajectory of the second massage unit 1211B may also be the same as that of the first massage unit 1211A.

[0195] Furthermore, in the above embodiments, the second massage portion 1211B may also be configured to have the same shape as the first massage portion 1211A.

[0196] Furthermore, in the above embodiments, the shapes of the first body 121A and the second body 121B are not limited to the shapes shown in the figure, and can be appropriately changed as needed.

[0197] Furthermore, in the above embodiment, the motor 131 is disposed between the first treatment arm 12A and the second treatment arm 12B in the extending direction of the rotating shaft 11, but it is not limited to this, and the position of the motor 131 can be adjusted appropriately according to the situation.

[0198] Furthermore, in the above embodiments, the first treatment arm 12A and the second treatment arm 12B are respectively eccentric and inclined relative to the rotation axis 11, but it is not limited to this. It is also possible to set only one of the first treatment arm 12A and the second treatment arm 12B to be eccentric and inclined relative to the rotation axis 11.

[0199] Furthermore, in the above embodiment, the first treatment arm 12A massages the patient from the front side and shoulder, and the second treatment arm 12B massages the patient from the back side and shoulder. However, it is not limited to this. It can also be configured such that the first treatment arm 12A massages the patient from the back side and shoulder, and the second treatment arm 12B massages the patient from the front side and shoulder.
