In the following description, the directions shown in the drawings are used as the directions when describing the chair type massage machine 1 of the present invention.

[0048] exist Figure 1 1 shows an example of a chair type massage machine 1 according to the present invention.

[0049] like Figure 1 As shown, the chair-type massage machine 1 of this embodiment includes a seat 2 on which a user U sits, a backrest 3 provided at the rear of the seat 2 , and a footrest 4 provided at the front of the seat 2 .

[0050] In addition, the chair-type massage machine 1 of the present embodiment has a back massage mechanism 5 for performing grabbing, kneading and massaging the treatment parts (shoulders, back, etc.) of the user U, a pressing massage mechanism for performing pressing massage on the treatment parts (sides of shoulders to sides of upper arms, buttocks, legs, etc.) of the user U, and a control unit for coordinating the grabbing, kneading and massaging performed by the back massage mechanism 5 with the pressing action performed by the pressing massage mechanism.

[0051] The pressing massage mechanism includes a first pressing mechanism for pressing the buttocks and legs of the user U upward, a second pressing mechanism for pressing the upper body of the user U forward, and a third pressing mechanism for pressing the upper body of the user U from the side to the inside.

[0052] In addition, one or more airbags may be provided as the first to third pressing mechanisms. In this embodiment, the airbag is described in detail by taking an example.

[0053] The pressing massage mechanism includes one or more airbags as the first to third pressing mechanisms. The airbags A to D of the first pressing mechanism are provided at least one on the upper surface of the seat 2 and on the left and right sides of the seat 2. The airbags G and H of the second pressing mechanism are provided at least one on the front surface of the backrest 3. The airbags E and F of the third pressing mechanism are provided at least one on the left and right sides of the backrest 3.

[0054] The pressing and massaging mechanism may be an air bag, but although not shown in the figure, the present invention may also be realized by a mechanical massaging mechanism as the first pressing mechanism.

[0055] The footrest 4 is provided with a pair of left and right insertion recesses 6L and 6R into which the foot (lower limbs) of the user U from below the knee can be respectively inserted. Inside these left and right insertion recesses 6L and 6R, a foot kneading mechanism 7 for kneading and massaging the lower limbs as one of the treatment parts is built in. The foot kneading mechanism 7 can be, for example, a kneading plate or an air bag that presses the lower limbs of the user U from the left and right to massage. In addition, the footrest 4 can also be configured to be able to be stored under the seat 2 with the help of a footrest moving mechanism 8.

[0056] A frame 9 for installing the chair type massage machine 1 on the floor is provided below the seat 2. The frame 9 is formed by combining a plurality of steel square materials into a foot warmer frame. The seat 2 is supported by the frame 9 at a predetermined height.

[0057] The seat 2 has a size sufficient to support the buttocks of the user U from below. A cushioning material is installed inside the seat 2, and a good sitting feeling is provided when sitting. In addition, a cloth is provided on the outside of the seat 2, for example, in a covering manner. The surface (upper surface) of the seat 2 has a good touch when sitting.

[0058] In this embodiment, two airbags A and B (first pressing mechanism) are arranged in the left-right direction on the upper surface of the seat 2 (the back side of the cloth covering the upper surface of the seat 2), forming a seat massage mechanism 10 (buttocks massage mechanism 10). The airbag A is arranged on the right side of the seat 2 to apply a pressing massage to the right buttocks and the back of the right leg of the user U. The airbag B is arranged on the left side of the seat 2 to apply a pressing massage to the left buttocks and the back of the left leg of the user U. That is, the airbags A and B are arranged in pairs on the upper surface of the seat 2.

[0059] The seat massage mechanism 10 supplies air from an air compressor to the left and right air bags A and B, and causes the left and right air bags A and B to expand and contract repeatedly at a predetermined rhythm, thereby performing a pressing massage such as pushing and pressing the buttocks, which is one of the treatment parts, from the bottom to the top. In addition, the expansion action of the left and right air bags A and B will be described in detail later.

[0060] Furthermore, in the present embodiment, armrests 11L and 11R capable of placing forearms are provided on the left and right sides of the seat 2. Two air bags C and D (first pressing mechanism) are arranged in the left and right directions on the inner side surfaces of the armrests 11L and 11R facing each other, forming a leg massage mechanism 12. In addition, in the present embodiment, arm massage mechanisms 13 are provided inside the left and right armrests 11L and 11R, respectively.

[0061] The airbag C is disposed between the left side surface of the right armrest 11R and the right side of the seat 2 to apply pressure massage to the right leg of the user U. The airbag D is disposed between the right side surface of the left armrest 11L and the left side of the seat 2 to apply pressure massage to the left leg of the user U. That is, the left and right airbags C and D are disposed in pairs on the left and right sides of the seat 2 at a distance of the width of the seat 2.

[0062] The leg massage mechanism 12 supplies air from the air compressor to the left and right air bags C and D, so that the left and right air bags C and D are repeatedly expanded and contracted at a predetermined rhythm, thereby performing a pressing massage such as pushing and pressing the leg, which is one of the treatment parts, from the left and right outer sides to the inner sides. In addition, the expansion action of the left and right air bags C and D will be described in detail later.

[0063] The lower end of the backrest 3 is pivotally supported relative to the rear of the seat 2, and is maintained in a state of being able to swing freely forward and backward. The backrest 3 can be tilted relative to the seat 2 by means of a tilting mechanism composed of a linear actuator disposed in a frame 9. In addition, a back massage mechanism 5 is provided inside the backrest 3, which can perform grabbing, kneading, and massaging massage alternately left and right.

[0064] The back massage mechanism 5 has a pair of left and right first arm members 14 (kneading arm members 14) having a first treatment member 15 at the front end and a pair of left and right second arm members 16 (grasping arm members 16) having a second treatment member 17 at the front end, and is configured to perform a "grasping and kneading massage" in which the left and right shoulders (treatment parts) are alternately grasped and kneaded by making the first treatment member 15 and the second treatment member 17 approach and separate from each other left and right. The detailed structure of the back massage mechanism 5 will be described later.

[0065] Furthermore, in the present embodiment, side plates 18L and 18R are provided on the left and right sides of the backrest portion 3. These side plates 18L and 18R are provided as flat plates that cover the upper body of the user U from the side. Two air bags E and F (third pressing mechanism) are provided inside the side plates 18L and 18R in the left-right direction, forming a side kneading mechanism 19.

[0066] The airbag E is arranged on the right side of the backrest 3 to perform a pressing massage such as pushing and pressing the side of the right shoulder and the side of the right upper arm of the user U. The airbag F is arranged on the left side of the backrest 3 to perform a pressing massage such as pushing and pressing the side of the left shoulder and the side of the left upper arm of the user U. That is, the left and right airbags E and F are arranged in pairs on the left and right sides of the backrest 3 at a distance of the width of the backrest 3.

[0067] The side kneading mechanism 19 supplies air from the air compressor to the left and right air bags E and F, so that the left and right air bags E and F are repeatedly expanded and contracted at a predetermined rhythm, thereby performing a pressing massage such as pushing the side of the shoulder and the side of the upper arm, which are one of the treatment parts. In addition, the expansion action of the left and right air bags E and F will be described in detail later.

[0068] In addition, in the present embodiment, two airbags G and H (second pressing mechanism) are arranged in the left-right direction on the back side of the front surface of the backrest 3, forming a back kneading mechanism 20. The airbag G is arranged on the right side of the front surface of the backrest 3, and performs a pressing massage such as pushing and pressing the right back of the user U from the back to the front. The airbag H is arranged on the left side of the front surface of the backrest 3, and performs a pressing massage such as pushing and pressing the left back of the user U from the back to the front. That is, the airbags G and H are arranged in pairs on the front surface of the backrest 3.

[0069] The back kneading mechanism 20 supplies air from the air compressor to the left and right air bags G, H, so that the left and right air bags G, H are repeatedly expanded and contracted at a predetermined rhythm, thereby performing a pressing massage such as pushing the back, which is one of the treatment parts, from the back to the front. In addition, the expansion action of the left and right air bags G, H will be described in detail later.

[0070] Thus, the chair-type massage machine 1 of this embodiment has a plurality of massage parts (back massage mechanism 5, seat massage mechanism 10, leg massage mechanism 12, side kneading mechanism 19, back kneading mechanism 20, foot kneading mechanism 7, etc.) for massaging various treatment parts.

[0071] The chair type massage machine 1 of this embodiment can press the shoulders (treatment area) more strongly or stretch the shoulders while squeezing them. Such a pressing massage can be achieved by making the back massage mechanism 5 cooperate with the airbags A to H and the like.

[0072] In addition, the chair-type massage machine 1 of the present invention is provided with a control unit for controlling the driving of the back massage mechanism 5 and the expansion and contraction of the air bags A to H. In the present invention, it is characterized in that the control unit can coordinate the action of the back massage mechanism 5 to alternately grasp, knead and massage the shoulders (treatment area) left and right with the action of pressing the buttocks, legs, upper arms, back, etc. by the expansion and contraction of the plurality of air bags A to H.

[0073] Below, while referring to Figure 2A to Figure 9The pressing massage action (grasping, kneading and pressing massage) performed by the cooperative action of the back massage mechanism 5 and the plurality of air bags A to H is described. These pressing massage actions are controlled and realized by the control unit built into the chair type massage machine 1. In this embodiment, the pressing massage actions of [cooperative massage 1] to [cooperative massage 7] are described in detail.

[0074] [Collaborative massage 1]

[0075] Figure 2A This is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 1 ) that can be controlled by a control unit provided in the chair-type massage machine 1 .

[0076] like Figure 2A As shown, the control unit performs the following "collaborative massage 1": the first treatment piece 15R and the second treatment piece 17R on the right side are brought close to each other in advance to grip the right shoulder of the user U, and the first treatment piece 15L and the second treatment piece 17L on the left side are moved away from each other, and the air bag A provided on the right side of the upper surface of the seat 2 and / or the air bag C (first pressing mechanism) provided on the right side of the seat 2 are inflated, thereby increasing the intensity of the treatment on the right shoulder gripped by the first treatment piece 15R and the second treatment piece 17R on the right side.

[0077] Specifically, the back massage mechanism 5 in the backrest portion 3 is moved so that the first treatment members 15R, 15L and the second treatment members 17R, 17L on the left and right sides are in positions where they can grasp and knead the shoulders on the left and right sides. When the back massage mechanism 5 is driven to move the first treatment member 15R and the second treatment member 17R on the right side closer to and away from each other, and then the first treatment member 15L and the second treatment member 17L on the left side closer to and away from each other, and a "grabbing and kneading massage" is performed to alternately grasp and knead the shoulders on the left and right sides, the user U here operates the controller of the chair-type massage machine 1 and gives the control unit an instruction of "cooperative massage 1".

[0078] The control unit that receives the instruction of "cooperative massage 1" moves the first treatment member 15R and the second treatment member 17R on the right side close to each other so as to grasp and knead the right shoulder (as shown by Figure 2A As indicated by the thick line, the right shoulder is in a maintained state), while on the other hand, the first treatment member 15L and the second treatment member 17L on the left side are separated from each other and become an open state (the left shoulder is in a free state).

[0079] Here, the control unit controls the first treatment member 15R and the second treatment member 17R on the right side to grasp the right shoulder. Figure 2A As indicated by the thick line, at least one of the airbag A (seat massage mechanism 10) or the airbag C (leg massage mechanism 12) on the right side of the plane of the seat 2 is inflated.

[0080] That is, the first treatment member 15R and the second treatment member 17R on the upper right side are operated in the order of grasping the right shoulder → inflating the airbag A and / or airbag B on the lower right side (the mechanism in the vertical direction of upper right → lower right).

[0081] As a result, the right side of the upper body of the user U is pushed upward, and the first treatment member 15R and the second treatment member 17R accurately sink into (enter) the right shoulder as the target treatment part, and press and massage the right shoulder more strongly and effectively.

[0082] That is, the user is lifted upward by the expansion of the airbag A and / or the airbag C, and the first treatment member 15R and the second treatment member 17R on the right side are in a state of partially pressing the right shoulder (acupoint pressing state).

[0083] In addition, even if the first treatment piece 15R and the second treatment piece 17R on the right side are pushed against the user's right shoulder with excessive force, since the airbag A can be recessed downward, the acupoint pressing state will hardly be felt as "painful", and a comfortable local pressing massage can be achieved.

[0084] [Variation 1 of Collaborative Massage 1]

[0085] Here, a modification 1 of the cooperative massage 1 is described. Specifically, in the cooperative massage 1, a case where one of the airbags E and F provided on the left and right sides of the backrest 3 is inflated while the right shoulder is squeezed by the first and second massage members 15R and 17R on the right side.

[0086] [Case 1]

[0087] exist Figure 2B 3 shows an example 1 of the modification 1 of the cooperative massage 1, that is, a schematic diagram of inflating the airbag F on the left side of the backrest portion 3 while grasping the right shoulder with the first treatment member 15R and the second treatment member 17R on the right side.

[0088] like Figure 2B As shown, the control unit of the pressing massage mechanism of this modified example brings the first treatment piece 15R and the second treatment piece 17R on the right side closer to each other to pinch the right shoulder of the user U, and moves the first treatment piece 15L and the second treatment piece 17L on the left side away from each other, so as to inflate the airbag F provided on the left side of the backrest portion 3, thereby increasing the intensity of the treatment on the pinched right shoulder.

[0089] Specifically, the first treatment member 15R and the second treatment member 17R on the right side are brought close to grasp the right shoulder of the user U, and the first treatment member 15L and the second treatment member 17L on the left side are separated. The right shoulder is held by grasping the first treatment member 15R and the second treatment member 17R on the right side.

[0090] Here, at least one of the airbag A (seat massage mechanism 10) or the airbag C (leg massage mechanism 12) provided on the right side of the plane of the seat 2 can be inflated. The body is supported by the inflation of the airbag A of the seat 2.

[0091] If the airbag F provided on the left side of the backrest portion 3 is inflated, the right shoulder pinched by the first treatment member 15R and the second treatment member 17R on the right side is loaded from the left, so that it is pushed more strongly, and the intensity of treatment on the pinched right shoulder can be increased (the right shoulder is pushed strongly to relieve stiffness).

[0092] [Case 2]

[0093] exist Figure 2C 2 shows Example 2 of Modification 1 of the cooperative massage 1, that is, a schematic diagram of inflating the airbag E on the right side of the backrest portion 3 while kneading the right shoulder with the first treatment member 15R and the second treatment member 17R on the right side.

[0094] like Figure 2C As shown, the control unit of the pressing massage mechanism of this modified example brings the first treatment piece 15R and the second treatment piece 17R on the right side closer to each other to pinch the right shoulder of the user U, and moves the first treatment piece 15L and the second treatment piece 17L on the left side away from each other, so as to inflate the airbag E provided on the right side of the backrest portion 3, thereby increasing the intensity of the treatment on the pinched right shoulder.

[0095] Specifically, the first treatment member 15R and the second treatment member 17R on the right side are brought close to grasp the right shoulder, and the first treatment member 15L and the second treatment member 17L on the left side are moved away from each other. The right shoulder of the user U is held by grasping the first treatment member 15R and the second treatment member 17R on the right side.

[0096] Here, at least one of the airbag A (seat massage mechanism 10) or the airbag C (leg massage mechanism 12) provided on the right side of the plane of the seat 2 can be inflated. The body is supported by the inflation of the airbag A of the seat 2.

[0097] If the airbag E provided on the right side of the backrest 3 is inflated, the upper body moves to the left, giving a stretching action (lateral stretching - stretching the right shoulder (treatment part) by sliding the grasping treatment parts laterally) to the right shoulder that is grasped by the first treatment piece 15R and the second treatment piece 17R on the right side, thereby increasing the intensity of the treatment on the grasped right shoulder.

[0098] [Variation 2 of Collaborative Massage 1]

[0099] Next, a modification 2 of the cooperative massage 1 will be described. That is, in the cooperative massage 1, a case where the first pressing mechanism (pressing massage mechanism) is a mechanical massage mechanism will be described.

[0100] The pressing massage mechanism of this modified example is different from the above in that it has a mechanical massage mechanism as the first pressing mechanism. The mechanical massage mechanism may be, for example, a mechanism that has a pair of left and right massage components (arm components) each having a treatment member at the front end and moves in the front-rear direction inside the seat 2. The massage component may be a component that performs eccentric motion or swing motion. In addition, the massage component may also be a component that performs massage motion alternately left and right.

[0101] In addition, the mechanical massage mechanism may include a mechanism in which the treatment piece (massage member) performs circular motion (having an up-and-down component) in the front-back direction. That is, the mechanical massage mechanism includes a mechanism in which the treatment piece moves upward in a side view.

[0102] In addition, the second pressing mechanism (airbags G, H) and the third pressing mechanism (airbags E, F) are the same as described above.

[0103] The basic cooperative action of the first treatment piece 15R and the second treatment piece 17R on the right side and the right treatment piece (mechanical massage mechanism) of the right massage part is roughly the same as the cooperative action of the first treatment piece 15R and the second treatment piece 17R on the right side and the airbag A and / or airbag C on the right side mentioned above, so it is briefly explained.

[0104] The control unit performs the following "collaborative massage 1": the first treatment piece 15R and the second treatment piece 17R on the right side are brought close to each other in advance to grip the right shoulder of the user U, and the first treatment piece 15L and the second treatment piece 17L on the left side are moved away from each other, and the right treatment piece (first pressing mechanism) of the right massage component provided on the right side of the seat 2 is used to press the right buttocks and / or right leg of the user upward, thereby increasing the intensity of the treatment on the right shoulder gripped by the first treatment piece 15R and the second treatment piece 17R on the right side.

[0105] The mechanical massage mechanism in the seat 2 is moved in the front-rear direction, for example, so that the right treatment member hits the right buttock. Then, the right buttock is lifted by the right treatment member, and the upper body (right side) of the user U is pushed upward, and the first treatment member 15R and the second treatment member 17R are accurately sunk into (entered) the right shoulder as the target treatment part, and the right shoulder is pressed and massaged more strongly and effectively.

[0106] [Collaborative Massage 2]

[0107] Figure 3AThis is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 2 ) that can be controlled by a control unit provided in the chair-type massage machine 1 .

[0108] like Figure 3A As shown, the control unit performs the following "collaborative massage 2": the first treatment piece 15L and the second treatment piece 17L on the left are brought close to each other in advance to grip the left shoulder of the user U, and the first treatment piece 15R and the second treatment piece 17R on the right are moved away from each other, and the airbag B provided on the left side of the upper surface of the seat 2 and / or the airbag D (first pressing mechanism) provided on the left side of the seat 2 are inflated, thereby increasing the intensity of the treatment on the left shoulder gripped by the first treatment piece 15L and the second treatment piece 17L on the left side.

[0109] Specifically, the back massage mechanism 5 in the backrest portion 3 is moved so that the first treatment members 15R, 15L and the second treatment members 17R, 17L on the left and right sides are in positions where they can grasp and knead the shoulders on the left and right sides. When the back massage mechanism 5 is driven, the first treatment member 15L and the second treatment member 17L on the left side are moved closer and further away, and the first treatment member 15R and the second treatment member 17R on the right side are moved closer and further away, and then the shoulders on the left and right sides are alternately grasped and kneaded repeatedly, the user U here operates the controller of the chair-type massage machine 1 and gives the control unit an instruction of "cooperative massage 2".

[0110] The control unit that receives the instruction of "cooperative massage 2" moves the first treatment member 15L and the second treatment member 17L on the left side close to each other so as to grasp and knead the left shoulder (as shown by Figure 3A As indicated by the thick line, the left shoulder is in a maintained state), while on the other hand, the first treatment member 15R and the second treatment member 17R on the right side are moved away from each other to become an open state (the right shoulder is in a free state).

[0111] Here, the control unit is in a state where the first treatment member 15L and the second treatment member 17L on the left side grasp the left shoulder, such as by Figure 3A As indicated by the thick line, at least one of the airbag B (seat massage mechanism 10) or the airbag D (leg massage mechanism 12) on the right side of the plane of the seat 2 is inflated.

[0112] That is, the mechanism (upper left → lower left vertical direction) is operated in the order of grasping the left shoulder with the first treatment member 15L and the second treatment member 17L on the upper left → inflating the airbag B and / or airbag D on the lower left.

[0113] As a result, the left side of the upper body of the user U is pushed upward, and the first treatment member 15L and the second treatment member 17L accurately sink into (enter) the left shoulder as the target treatment part, and press and massage the left shoulder more strongly and effectively.

[0114] That is, by the expansion of the airbag B and / or the airbag D, the user is lifted upward, and the first treatment member 15L and the second treatment member 17L on the left side are in a state of partially pressing the left shoulder (acupoint pressing state).

[0115] In addition, even if the first treatment piece 15L and the second treatment piece 17L on the left side are pushed against the user's left shoulder with excessive force, since the airbag B can be recessed downward, the acupoint pressing state will hardly be felt as "painful", and a comfortable local pressing massage can be achieved.

[0116] [Variation 1 of Collaborative Massage 2]

[0117] Here, a modification 1 of the cooperative massage 2 is described. Specifically, in the cooperative massage 2, a case where one of the airbags E and F provided on the left and right sides of the backrest 3 is inflated while the left first and second treatment members 15L and 17L are used to squeeze the left shoulder is described.

[0118] [Case 1]

[0119] exist Figure 3B 2 shows an example 1 of the variation 1 of the cooperative massage 2, that is, a schematic diagram of inflating the airbag E on the right side of the backrest portion 3 while the left shoulder is grasped and kneaded by the first treatment member 15L and the second treatment member 17L on the left side.

[0120] like Figure 3B As shown, the control unit of the pressing massage mechanism of this modified example brings the first treatment piece 15L and the second treatment piece 17L on the left side closer to each other to pinch the left shoulder of the user U, and moves the first treatment piece 15R and the second treatment piece 17R on the right side away from each other, so as to inflate the airbag E provided on the right side of the backrest 3, thereby increasing the intensity of the treatment on the pinched left shoulder.

[0121] Specifically, the first treatment member 15L and the second treatment member 17L on the left side are brought close to each other to grasp the left shoulder of the user U, and the first treatment member 15R and the second treatment member 17R on the right side are moved away from each other. The left shoulder of the user U is held by grasping the first treatment member 15L and the second treatment member 17L on the left side.

[0122] Here, at least one of the airbag B (seat massage mechanism 10) or the airbag D (leg massage mechanism 12) provided on the left side of the plane of the seat 2 can be inflated. The body is supported by the inflation of the airbag B of the seat 2.

[0123] If the airbag E provided on the right side of the backrest 3 is inflated, a load is applied from the right to the left shoulder grasped by the first treatment piece 15L and the second treatment piece 17L on the left side, so that the left shoulder is pushed more strongly, thereby increasing the intensity of the treatment on the grasped left shoulder (pushing the left shoulder strongly to relieve stiffness).

[0124] [Case 2]

[0125] exist Figure 3C 2 shows a schematic diagram of Example 2 of Modification 1 of the cooperative massage 2, that is, in which the airbag F on the left side of the backrest portion 3 is inflated while the left shoulder is grasped and kneaded by the first treatment member 15L and the second treatment member 17L on the left side.

[0126] like Figure 3C As shown, the control unit of the pressing massage mechanism of this modified example brings the first treatment piece 15L and the second treatment piece 17L on the left side closer to each other in advance to pinch the left shoulder of the user U, and moves the first treatment piece 15R and the second treatment piece 17R on the right side away from each other, so as to inflate the airbag F provided on the left side of the backrest portion 3, thereby increasing the intensity of the treatment on the pinched left shoulder.

[0127] Specifically, the first treatment member 15L and the second treatment member 17L on the left side are brought close to each other to grasp the left shoulder, and the first treatment member 15R and the second treatment member 17R on the right side are moved away from each other. The left shoulder of the user U is held by grasping the first treatment member 15L and the second treatment member 17L on the left side.

[0128] Here, at least one of the airbag B (seat massage mechanism 10) or the airbag D (leg massage mechanism 12) provided on the left side of the plane of the seat 2 can be inflated. The body is supported by the inflation of the airbag B of the seat 2.

[0129] If the airbag F provided on the left side of the backrest 3 is inflated, the upper body moves to the right, giving a stretching action (lateral stretching - stretching the left shoulder (treatment part) by sliding the grasping treatment parts laterally) to the left shoulder that is grasped by the first treatment piece 15L and the second treatment piece 17L on the left side, thereby increasing the intensity of the treatment on the grasped left shoulder.

[0130] [Variation 2 of Collaborative Massage 2]

[0131] Next, a modification 2 of the cooperative massage 2 will be described. That is, in the cooperative massage 2, a case where the first pressing mechanism (pressing massage mechanism) is a mechanical massage mechanism will be described.

[0132] The pressing massage mechanism of this modified example is different from the above in that it has a mechanical massage mechanism as the first pressing mechanism. The mechanical massage mechanism may be, for example, a mechanism that has a pair of left and right massage components (arm components) each having a treatment member at the front end and moves in the front-rear direction inside the seat 2. The massage component may be a component that performs eccentric motion or swing motion. In addition, the massage component may also be a component that performs massage motion alternately left and right.

[0133] In addition, the mechanical massage mechanism may include a mechanism in which the treatment piece (massage member) performs circular motion (having an up-and-down component) in the front-back direction. That is, the mechanical massage mechanism includes a mechanism in which the treatment piece moves upward in a side view.

[0134] In addition, the second pressing mechanism (airbags G, H) and the third pressing mechanism (airbags E, F) are the same as described above.

[0135] The basic cooperative action of the first treatment piece 15L and the second treatment piece 17L on the left side and the left treatment piece (mechanical massage mechanism) of the left massage part is roughly the same as the cooperative action of the first treatment piece 15L and the second treatment piece 17L on the left side and the airbag B and / or airbag D on the left side mentioned above, so it is briefly explained.

[0136] The control unit performs the following "collaborative massage 2": the first treatment piece 15L and the second treatment piece 17L on the left are brought close to each other in advance to grip the left shoulder of the user U, and the first treatment piece 15R and the second treatment piece 17R on the right are moved away from each other, and the left treatment piece (first pressing mechanism) of the left massage component provided on the left side of the seat 2 is used to press the left buttocks and / or left leg of the user upward, thereby increasing the intensity of the treatment on the left shoulder gripped by the first treatment piece 15L and the second treatment piece 17L on the left side.

[0137] The mechanical massage mechanism in the seat 2 is moved in the front-rear direction, for example, the left treatment piece is brought into contact with the left buttock. Then, the left buttock is lifted by the left treatment piece, the upper body (left side) of the user U is pushed upward, and the first treatment piece 15L and the second treatment piece 17L are accurately sunk into (entered) the left shoulder as the target treatment part, and the left shoulder is pressed and massaged more strongly and effectively.

[0138] [Collaborative Massage 3]

[0139] exist Figure 4 2 is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 3) that can be controlled by a control unit provided in the chair-type massage machine 1.

[0140] like Figure 4As shown, the control unit performs the following "collaborative massage 3": the first treatment piece 15R and the second treatment piece 17R on the right side are brought close to each other in advance to grip the right shoulder of the user U, and the first treatment piece 15L and the second treatment piece 17L on the left side are moved away from each other, and the airbag B provided on the left side of the upper surface of the seat 2 and / or the airbag D (first pressing mechanism) provided on the left side of the seat 2 are inflated, thereby giving a stretching action (lateral stretching·stretching the right shoulder (treatment part) by sliding the gripping treatment pieces laterally) to the right shoulder gripped by the first treatment piece 15R and the second treatment piece 17R on the right side.

[0141] Specifically, the back massage mechanism 5 in the backrest portion 3 is moved so that the first treatment members 15R, 15L and the second treatment members 17R, 17L on the left and right sides are in positions where they can grasp and knead the shoulders on the left and right sides. When the back massage mechanism 5 is driven to move the first treatment member 15R and the second treatment member 17R on the right side closer to and away from each other, and then the first treatment member 15L and the second treatment member 17L on the left side closer to and away from each other, and a "grabbing and kneading massage" is performed to alternately grasp and knead the shoulders on the left and right sides, the user U here operates the controller of the chair-type massage machine 1 and gives the control unit an instruction of "cooperative massage 3".

[0142] The control unit that receives the instruction of "cooperative massage 3" moves the first treatment member 15R and the second treatment member 17R on the right side close to each other so as to grasp and knead the right shoulder (as shown by Figure 4 As indicated by the thick line, the right shoulder is in a maintained state), while on the other hand, the first treatment member 15L and the second treatment member 17L on the left side are separated from each other and become an open state (the left shoulder is in a free state).

[0143] Here, the control unit controls the first treatment member 15R and the second treatment member 17R on the right side to grasp the right shoulder. Figure 4 As indicated by the bold line, at least one of the airbag B (seat massage mechanism 10) or the airbag D provided on the left side of the seat 2 is inflated (leg massage mechanism 12).

[0144] That is, the first treatment member 15R and the second treatment member 17R on the upper right side are operated in the order of grasping the right shoulder → inflating the airbag B and / or airbag D on the lower left side (the mechanism in the diagonal direction of upper right → lower left).

[0145] As a result, the left side of the upper body of the user U is pushed upward and tilted to the right, but the first treatment piece 15R and the second treatment piece 17R on the right side are in a state of gripping the right shoulder. As a result, the first treatment piece 15R and the second treatment piece 17R on the right side slide laterally while gripping the right shoulder, thereby stretching the right shoulder (treatment part).

[0146] In addition, the first treatment member 15R and the second treatment member 17R are accurately sunk into (entered into) the right shoulder, and can also effectively and more strongly press and massage the right shoulder.

[0147] That is, the user is lifted upward by the expansion of the airbag B and / or the airbag D, and the first treatment member 15R and the second treatment member 17R on the right side are in a state of partially pressing the right shoulder (acupoint pressing state).

[0148] In addition, even if the first treatment piece 15R and the second treatment piece 17R on the right side are pushed against the user's right shoulder with excessive force, since the airbag B can be recessed downward, the acupoint pressing state will hardly be felt as "painful", and a comfortable local pressing massage can be achieved.

[0149] [Variation of Collaborative Massage 3]

[0150] Here, a modification of the cooperative massage 3 will be described. That is, in the cooperative massage 3, a case where the first pressing mechanism (pressing massage mechanism) is a mechanical massage mechanism will be described.

The mechanical massage mechanism may be, for example, a mechanism that has a pair of left and right massage components (arm components) each having a treatment member at the front end and moves in the front-rear direction inside the seat 2. The massage component may be a component that performs eccentric motion or swing motion. In addition, the massage component may also be a component that performs massage motion alternately left and right.

[0152] In addition, the mechanical massage mechanism may include a mechanism in which the treatment piece (massage member) performs circular motion (having an up-and-down component) in the front-back direction. That is, the mechanical massage mechanism includes a mechanism in which the treatment piece moves upward in a side view.

[0153] In addition, the second pressing mechanism (airbags G, H) and the third pressing mechanism (airbags E, F) are the same as described above.

[0154] The basic cooperative action of the first treatment piece 15R and the second treatment piece 17R on the right side and the left treatment piece (mechanical massage mechanism) of the left massage part is roughly the same as the cooperative action of the first treatment piece 15R and the second treatment piece 17R on the right side and the airbag B and / or airbag D on the left side mentioned above, so it is briefly explained.

[0155] The control unit performs the following "collaborative massage 3": the first treatment piece 15R and the second treatment piece 17R on the right side are brought close to each other in advance to grasp the right shoulder of the user U, and the first treatment piece 15L and the second treatment piece 17L on the left side are moved away from each other, and the left treatment piece (first pressing mechanism) of the left massage component provided on the left side of the seat 2 is used to press the left buttocks and / or left leg of the user upward, thereby increasing the intensity of the treatment on the right shoulder grasped by the first treatment piece 15R and the second treatment piece 17R on the right side.

[0156] The mechanical massage mechanism in the seat 2 is moved in the front-rear direction, for example, the left treatment piece is brought into contact with the left buttock. Then, the left buttock is lifted by the left treatment piece, and the left side of the upper body of the user U is pushed upward and tilted to the right, but the first treatment piece 15R and the second treatment piece 17R on the right side are in a state of grasping the right shoulder, so that the first treatment piece 15R and the second treatment piece 17R on the right side slide in the horizontal direction while grasping the right shoulder, thereby stretching the right shoulder (treatment part).

[0157] In addition, the first treatment member 15R and the second treatment member 17R are accurately sunk into (entered into) the right shoulder, and can also effectively and more strongly press and massage the right shoulder.

[0158] [Collaborative Massage 4]

[0159] Figure 5 This is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 4 ) that can be controlled by a control unit provided in the chair-type massage machine 1 .

[0160] like Figure 5 As shown, the control unit performs the following "collaborative massage 4": the first treatment piece 15L and the second treatment piece 17L on the left are brought close to each other in advance to grip the left shoulder of the user U, and the first treatment piece 15R and the second treatment piece 17R on the right are moved away from each other, and the airbag A provided on the right side of the upper surface of the seat 2 and / or the airbag C (first pressing mechanism) provided on the right side of the seat 2 are inflated, thereby giving a stretching action (lateral stretching·stretching the left shoulder (treatment part) by sliding the gripping treatment piece laterally) to the left shoulder gripped by the first treatment piece 15L and the second treatment piece 17L on the left.

[0161] In detail, the back massage mechanism 5 in the backrest portion 3 is moved so that the first treatment members 15R, 15L and the second treatment members 17R, 17L on the left and right are in positions where they can grasp and knead the shoulders on the left and right. When the back massage mechanism 5 is driven to move the first treatment member 15L and the second treatment member 17L on the left side closer to and away from each other, and then the first treatment member 15R and the second treatment member 17R on the right side closer to and away from each other, and a "grabbing and kneading massage" is performed in which the shoulders on the left and right are grasped and kneaded alternately and repeatedly, the user U here operates the controller of the chair-type massage machine 1 and gives the control unit an instruction of "cooperative massage 4".

[0162] The control unit that receives the instruction of "cooperative massage 4" moves the first treatment member 15L and the second treatment member 17L on the left side close to each other so as to grasp and knead the left shoulder (as shown by Figure 5 As indicated by the thick line, the left shoulder is in a maintained state), while on the other hand, the first treatment member 15R and the second treatment member 17R on the right side are separated from each other and become an open state (the right shoulder is in a free state).

[0163] Here, the control unit is in a state where the first treatment member 15L and the second treatment member 17L on the left side grasp the left shoulder, such as by Figure 5 As indicated by the bold line, at least one of the airbag A (seat massage mechanism 10) or the airbag C (leg massage mechanism 12) provided on the right side of the seat 2 is inflated.

[0164] That is, the first treatment member 15L and the second treatment member 17L on the upper left side are operated in the order of grasping the left shoulder → inflating the airbag A and / or airbag C on the lower right side (the mechanism in the diagonal direction of the upper left → the lower right).

[0165] As a result, the right side of the upper body of the user U is pushed upward and tilted to the left, but the first treatment piece 15L and the second treatment piece 17L on the left side are in a state of gripping the left shoulder. As a result, the first treatment piece 15L and the second treatment piece 17L on the left side slide laterally while gripping the left shoulder, thereby stretching the left shoulder (treatment part).

[0166] In addition, the first treatment member 15L and the second treatment member 17L are accurately sunk into (entered into) the left shoulder, and can also effectively and more strongly press and massage the left shoulder.

[0167] That is, by the expansion of the airbag A and / or the airbag C, the user is lifted upward, and the first treatment member 15L and the second treatment member 17L on the left side are in a state of partially pressing the left shoulder (acupoint pressing state).

[0168] In addition, even if the first treatment piece 15L and the second treatment piece 17L on the left side are pushed against the user's left shoulder with excessive force, since the airbag A can be recessed downward, the acupoint pressing state will hardly be felt as "painful", and a comfortable local pressing massage can be achieved.

[0169] [Variation of Collaborative Massage 4]

[0170] Here, a modification of the cooperative massage 4 will be described. That is, in the cooperative massage 4, a case where the first pressing mechanism (pressing massage mechanism) is a mechanical massage mechanism will be described.

[0172] In addition, the mechanical massage mechanism may include a mechanism in which the treatment piece (massage member) performs circular motion (having an up-and-down component) in the front-back direction. That is, the mechanical massage mechanism includes a mechanism in which the treatment piece moves upward in a side view.

[0173] The second pressing mechanism (airbags G and H) and the third pressing mechanism (airbags E and F) are the same as those described above.

[0174] The basic cooperative action of the first treatment piece 15L and the second treatment piece 17L on the left side and the right treatment piece (mechanical massage mechanism) of the right massage part is roughly the same as the cooperative action of the first treatment piece 15L and the second treatment piece 17L on the left side and the airbag A and / or airbag C on the right side mentioned above, so it is briefly explained.

[0175] The control unit performs the following "collaborative massage 4": the first treatment piece 15L and the second treatment piece 17L on the left side are brought close to each other in advance to grip the left shoulder of the user U, and the first treatment piece 15R and the second treatment piece 17R on the right side are moved away from each other, and the right treatment piece (first pressing mechanism) of the right massage component provided on the right side of the seat 2 is used to press the right buttocks and / or right leg of the user upward, thereby increasing the intensity of the treatment on the left shoulder gripped by the first treatment piece 15L and the second treatment piece 17L on the left side.

[0176] The mechanical massage mechanism in the seat 2 is moved in the front-rear direction, for example, so that the right treatment piece hits the right buttock. Then, the right buttock is lifted by the right treatment piece, and the right side of the upper body of the user U is pushed upward and tilted to the left, but the first treatment piece 15L and the second treatment piece 17L on the left side are in a state of grasping the left shoulder, so that the first treatment piece 15L and the second treatment piece 17L on the left side slide in the horizontal direction while grasping the left shoulder, thereby stretching the left shoulder (treatment part).

[0177] In addition, the first treatment member 15L and the second treatment member 17L are accurately sunk into (entered into) the left shoulder, and can also effectively and more strongly press and massage the left shoulder.

[0178] [Collaborative Massage 5]

[0179] Figure 6 This is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 5 ) that can be controlled by a control unit provided in the chair-type massage machine 1 . Fig. 9 This is a left side view schematically showing an example of grabbing, kneading and massaging actions that can be controlled by the control unit provided in the chair-type massage machine 1 .

[0180] like Figure 6 , Fig. 9 As shown in the figures, the control unit performs the following "cooperative massage 5": the first treatment piece 15R and the second treatment piece 17R on the right side are brought close to each other in advance to grasp the right shoulder of the user U, and the first treatment piece 15L and the second treatment piece 17L on the left side are moved away from each other, and the air bag H (second pressing mechanism) provided on the left side of the backrest 3 is inflated, thereby imparting a twist to the left side of the upper body of the user U, thereby increasing the intensity of the treatment on the right shoulder grasped by the first treatment piece 15R and the second treatment piece 17R on the right side.

[0181] Specifically, the back massage mechanism 5 in the backrest portion 3 is moved so that the first treatment members 15R, 15L and the second treatment members 17R, 17L on the left and right sides are in positions where they can grasp and knead the shoulders on the left and right sides. When the back massage mechanism 5 is driven to move the first treatment member 15R and the second treatment member 17R on the right side closer to and away from each other, and then the first treatment member 15L and the second treatment member 17L on the left side closer to and away from each other, and a "grabbing and kneading massage" is performed to alternately grasp and knead the shoulders on the left and right sides, the user U here operates the controller of the chair-type massage machine 1 and gives the control unit an instruction of "cooperative massage 5".

[0182] The control unit that receives the instruction of "cooperative massage 5" moves the first treatment member 15R and the second treatment member 17R on the right side close to each other so as to grasp and knead the right shoulder (as shown by Figure 6As indicated by the thick line, the right shoulder is in a maintained state), while on the other hand, the first treatment member 15L and the second treatment member 17L on the left side are separated from each other and become an open state (the left shoulder is in a free state).

[0183] Here, the control unit controls the first treatment member 15R and the second treatment member 17R on the right side to grasp the right shoulder. Figure 6 As indicated by the thick line, the air bag H (back kneading mechanism 20) provided on the left side of the backrest portion 3 is inflated.

[0184] That is, the first treatment member 15R and the second treatment member 17R on the upper right side are operated in the order of grasping the right shoulder → inflating the airbag H on the left and substantially the center (mechanism in the diagonal direction of upper right → middle left).

[0185] Then, the left side of the back of the user U is pushed forward, causing the left upper body to twist. At this time, the left side of the body is stretched. The first treatment member 15R and the second treatment member 17R on the right side slide in the horizontal direction while grasping the right shoulder, stretching the right shoulder (treatment part).

[0186] In addition, the first treatment member 15R and the second treatment member 17R are accurately sunk into (entered into) the right shoulder, and can also effectively and more strongly press and massage the right shoulder.

[0187] That is, with the expansion of the airbag H, the left side of the user's upper body is pushed forward and twisted, and the first treatment member 15R and the second treatment member 17R on the right side are in a state of partially pressing the right shoulder (acupoint pressing state).

[0188] In addition, even if the first treatment piece 15R and the second treatment piece 17R on the right side are pushed against the user's right shoulder with excessive force, since the airbag H can be recessed backward, the acupoint pressing state will hardly be felt as "painful", and a comfortable local pressing massage can be achieved.

[0189] [Collaborative Massage 6]

[0190] Figure 7 This is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 6 ) that can be controlled by a control unit provided in the chair-type massage machine 1 .

[0191] like Figure 7 , Fig. 9As shown in the figures, the control unit performs the following "cooperative massage 6": the first treatment piece 15L and the second treatment piece 17L on the left side are brought close to each other in advance to grasp the left shoulder of the user U, and the first treatment piece 15R and the second treatment piece 17R on the right side are moved away from each other, and the air bag G (second pressing mechanism) provided on the right side of the backrest 3 is inflated, thereby imparting a twist to the right side of the upper body of the user U, thereby increasing the intensity of the treatment on the left shoulder grasped by the first treatment piece 15L and the second treatment piece 17L on the left side.

[0192] Specifically, the back massage mechanism 5 in the backrest portion 3 is moved so that the first treatment members 15R, 15L and the second treatment members 17R, 17L on the left and right sides are in positions where they can grasp and knead the shoulders on the left and right sides. When the back massage mechanism 5 is driven to move the first treatment member 15L and the second treatment member 17L on the left side closer to and away from each other, and then the first treatment member 15R and the second treatment member 17R on the right side closer to and away from each other, and a "grabbing and kneading massage" is performed in which the shoulders on the left and right sides are grasped and kneaded alternately and repeatedly, the user U here operates the controller of the chair-type massage machine 1 and gives the control unit an instruction of "cooperative massage 6".

[0193] The control unit that receives the instruction of "cooperative massage 6" moves the first treatment member 15L and the second treatment member 17L on the left side close to each other so as to grasp and knead the left shoulder (as shown by Figure 7 As indicated by the thick line, the left shoulder is in a maintained state), while on the other hand, the first treatment member 15R and the second treatment member 17R on the right side are separated from each other and become an open state (the right shoulder is in a free state).

[0194] Here, the control unit is in a state where the first treatment member 15L and the second treatment member 17L on the left side grasp the left shoulder, such as by Figure 7 As indicated by the thick line, the airbag G (back kneading mechanism 20) provided on the right side of the backrest portion 3 is inflated.

[0195] That is, the first treatment member 15L and the second treatment member 17L on the upper left side are operated in the order of grasping the right shoulder → inflating the airbag G on the right and substantially in the center (the mechanism in the diagonal direction of the upper left → the middle right).

[0196] Then, the right side of the back of the user U is pushed forward, causing the upper body on the right side to twist. At this time, the right side of the body is stretched. The first treatment member 15L and the second treatment member 17L on the left side slide in the lateral direction while grasping the left shoulder, stretching the left shoulder (treatment part).

[0197] In addition, the first treatment member 15L and the second treatment member 17L are accurately sunk into (entered into) the left shoulder, and can effectively and more strongly press and massage the left shoulder.

[0198] That is, with the expansion of the airbag G, the right side of the user's upper body is pushed forward and twisted, and the first treatment member 15L and the second treatment member 17L on the left side are in a state of partially pressing the left shoulder (acupoint pressing state).

[0199] In addition, even if the first treatment piece 15L and the second treatment piece 17L on the left side are pushed against the user's left shoulder with excessive force, since the airbag G can be recessed backward, the acupoint pressing state will hardly be felt as "painful", and a comfortable local pressing massage can be achieved.

[0200] [Collaborative Massage 7]

[0201] Figure 8 This is a schematic front view schematically showing an example of a grabbing, kneading, and pressing massage action (cooperative massage 7 ) that can be controlled by a control unit provided in the chair-type massage machine 1 .

[0202] like Figure 8 As shown, the control unit performs the following "collaborative massage 7": while the left and right shoulders of the user U are alternately grasped, kneaded and massaged by the left and right first treatment members 15L, 15R and the second treatment members 17L, 17R, the air bags E, F (third pressing mechanism) provided on the left and right sides of the backrest 3 are inflated to hold the upper body of the user U.

[0203] That is, the "cooperative massage 7" suppresses the left-right swaying of the upper body that occurs when the shoulders are subjected to grabbing, kneading and massaging by the first treatment members 15L, 15R and the second treatment members 17L, 17R alternately left and right.

[0204] In detail, the back massage mechanism 5 is moved so that the left and right first treatment members 15R, 15L and the second treatment members 17R, 17L are in positions where the left and right shoulders can be grasped and kneaded. When the left first treatment member 15L and the second treatment member 17L are moved closer and further away, and then the right first treatment member 15R and the second treatment member 17R are moved closer and further away, and the left and right shoulders are alternately grasped and kneaded repeatedly, the upper body of the user U leaning on the backrest 3 is swung left and right by the swing of the left and right first arm members 14L, 14R and the second arm members 16L, 16R.

[0205] In order to prevent the above situation, the user U operates the controller of the chair type massage machine 1 to give the control unit an instruction of "cooperative massage 7". The control unit that receives the instruction of "cooperative massage 7" Figure 8 As indicated by the thick line, the airbags E and F (side kneading mechanism 19) provided on the left and right sides of the backrest portion 3 are inflated to hold the upper body of the user U.

[0206] The back massage mechanism 5 is driven to move the first treatment member 15L and the second treatment member 17L on the left side closer and farther away, and then the first treatment member 15R and the second treatment member 17R on the right side closer and farther away, to perform a "grabbing and kneading massage" in which the left and right shoulders are alternately and repeatedly grasped and kneaded.

[0207] As described above, the chair-type massage machine 1 of the present invention controls the collaborative action of "the action of alternately pinching and kneading the shoulders (treatment area) left and right by the back massage mechanism 5" and "the pressing action of the buttocks, legs, upper arms, back, etc. by multiple air bags A~H (seat massage mechanism 10 (first pressing mechanism), leg massage mechanism 12 (first pressing mechanism), side kneading mechanism 19 (third pressing mechanism), back kneading mechanism 20 (second pressing mechanism)), etc.)" through the control unit, and can press the treatment area including the shoulders more strongly or pinch and stretch the shoulders as in "collaborative massage 1" to "collaborative massage 7", and can relieve the stiffness of the treatment area such as the shoulders without causing discomfort.

[0208] Next, the structure of the back massage mechanism 5 of this embodiment is described. When realizing the cooperative massage in the present invention, various massage mechanisms can be used, but the preferred back massage mechanism 5 is described below. In addition, the embodiment of the back massage mechanism 5 described below is an example and does not limit the structure of the present invention.

[0209] Fig.10 It is a perspective view showing the structure of the back massage mechanism 5 , and is a view in which the switching unit 26 is exploded. Fig.11 It is a bottom view showing the grabbing, kneading and massaging action performed by the back massage mechanism 5 (left figure: the first pinching action (grabbing, kneading alternately left and right), right figure: the second pinching action (grabbing, kneading simultaneously left and right)). Fig.12 It is a front view showing the grabbing, kneading and massaging action performed by the back massage mechanism 5 (left figure: the first pinching action (grabbing, kneading alternately left and right), right figure: the second pinching action (grabbing, kneading simultaneously left and right)).

[0210] like Figure 10 to Figure 12 As shown in the figures, the back massage mechanism 5 of the present embodiment is capable of performing a "first pinching action" of alternately performing grabbing, kneading and massaging the left and right shoulders (treatment parts) of the user U with the left and right first treatment members 15 and the second treatment members 17, and a "second pinching action" of simultaneously performing grabbing, kneading and massaging the left and right shoulders of the user U with the left and right first treatment members 15 and the second treatment members 17.

[0211] In addition, the back massage mechanism 5 of the present embodiment may be stopped in advance in a state where the first treatment member 15 and the second treatment member 17 are gripping and kneading either the left or right shoulder of the user U.

[0212] The back massage mechanism 5 of this embodiment includes: a driving part 22, which is arranged on the base 21 and generates a rotational driving force; a rotation driving shaft 23, which is arranged on the base 21 with its axis facing the left-right direction and rotates with the help of the rotational driving force; a massage part 24, which has treatment parts 15 and 17 on the front end side and is arranged in a pair of left and right on the base 21; a conversion part 25, which is arranged on the rotation driving shaft 23 and converts the rotational driving force into a clamping action (swinging motion) and transmits it to the massage part 24; and a switching part 26, which switches the phase of the clamping action of the massage part 24 with the help of the positive rotation and reverse rotation of the rotation driving shaft 23.

[0213] In addition, in this embodiment, the switching part 26 is provided on the right massage part 24R side. That is, the phase of the sandwiching operation of the right massage part 24R is switched with respect to the phase (constant phase) of the sandwiching operation of the left massage part 24L.

[0214] like Fig.10 As shown, the drive unit 22 has a drive motor 27 that outputs a rotational driving force and a gear box 28 that decelerates the outputted rotational driving force to a predetermined speed. The drive motor 27 is a motor that can rotate forward and reverse. The drive motor 27 is controlled by the control unit to control the rotation direction, speed, etc. That is, the drive unit 22 decelerates the rotational driving force generated by the drive motor 27 with the gear box 28 and transmits it to the rotation drive shaft 23.

[0215] The rotating drive shaft 23 is provided so as to penetrate the base 21 (gear box 28) and to have its axis facing the left-right direction (horizontal direction). The rotating drive shaft 23 is a long round rod-shaped shaft member, and is supported by bearings and the like so as to be able to switch the direction of rotation freely. The rotating drive shaft 23 is provided so as to be orthogonal to the output shaft of the drive motor 27.

[0216] That is, the rotary drive shaft 23 is provided with the driving part 22 in the middle of the longitudinal direction and the massage parts 24L and 24R are provided at the left and right ends. The rotary drive shaft 23 distributes the rotary driving force output from the driving motor 27 to the pair of left and right massage parts 24L and 24R.

[0217] In addition, if Fig.10 As shown, regarding the rotation of the rotation drive shaft 23, in this embodiment, "positive rotation" is defined as rotation in the direction of back, up, and forward, and "reverse rotation" is defined as rotation in the direction of forward, up, and backward. Regarding the definition of the rotation of the rotation drive shaft 23, positive and negative rotations may be defined as opposite.

[0218] like Fig.10 As shown, the massage part 24 is composed of a right massage part 24R for massaging the right treatment part and a left massage part 24L for massaging the left treatment part. The massage part 24 has a pair of upper and lower arm members 14 and 16.

[0219] The right massage part 24R will be described. The left massage part 24L has a structure that is a mirror image of the right massage part 24R, and therefore a detailed description thereof will be omitted.

[0220] The right massage part 24R includes a first arm member 14R (kneading arm member 14R) for kneading and massaging the upper right side of the shoulder, and a second arm member 16R (grabbing arm member 16R) for grabbing and massaging the lower right side of the shoulder.

[0221] like Fig.10 As shown, the front end of the first arm member 14R (kneading arm member 14R) on the right side is arranged to protrude forward, and a first right annular fitting portion 33R is arranged at the base end. The first right annular fitting portion 33R is a component constituting the right conversion portion 25R described later, and fits the first right rotation boss 32R from the outside.

[0222] The base end (first right annular fitting portion 33R) of the first arm member 14R is provided with the rotation drive shaft 23 in a penetrating state. On the other hand, the front end of the first arm member 14R is provided with the first treatment member 15R (upper treatment member 15R) capable of kneading and massaging the shoulder.

[0223] Furthermore, a ball joint 29 is provided at the base end of the first arm member 14R. The ball joint 29 is rotatably connected to the front end of a connecting shaft 30. The base end of the connecting shaft 30 is rotatably connected to a rotating shaft 31. The rotating shaft 31 is connected to a second drive motor 52 provided in the base 21.

[0224] Thus, if the rotating shaft 31 rotates by the rotational driving force output from the second driving motor 52, the first arm member 14R swings in the front-rear direction via the ball joint 39 and the connecting shaft 30, so that the tapping massage by the first treatment member 15R can also be performed. That is, the back massage mechanism 5 of this embodiment is equipped with a tapping massage mechanism that can also perform tapping massage by the first arm member 14R.

[0225] The first treatment member 15R is attached to the front end of the first arm member 14R in a shape protruding forward. The first treatment member 15R is a spherical member and is rotatably attached around an axis in a protruding direction toward the front end and around an axis in a direction intersecting the protruding direction.

[0226] The first treatment member 15R is disposed at a position vertically opposed to the second treatment member 17R described later. The first treatment member 15R swings in the left-right direction, and the second treatment member 17R moves closer to and away from the first treatment member 15R in the vertical direction. That is, the first treatment member 15R performs kneading massage on the upper side of the right shoulder by swinging the first arm member 14R with the help of the rotational driving force of the rotational driving shaft 23.

[0227] In addition, if Fig.10 As shown, a first conversion unit 25 is provided at the base end side of the first arm member 14 to convert the rotational driving force into a swinging motion and transmit it to the first arm member 14. The first conversion unit 25 is composed of a first right conversion unit 25R that converts the rotational driving force into a swinging motion of the first arm member 14R on the right side and a first left conversion unit 25L that converts the rotational driving force into a swinging motion of the first arm member 14L on the left side.

[0228] The first right conversion portion 25R includes a first right rotating protrusion 32R installed on the rotating drive shaft 23 and rotating integrally with the rotating drive shaft 23, a first right annular fitting portion 33R provided at the base end of the first arm member 14R and externally fitted with the first right rotating protrusion 32R, and a first right limiting portion 34R limiting the first arm member 14R from rotating together with the rotating drive shaft 23.

[0229] In addition, the first left conversion unit 25L has a structure that is a mirror-inverted structure of the first right conversion unit 25R, and therefore the description thereof is omitted.

[0230] The first right-rotating boss 32R is a component provided on the right end side of the rotation drive shaft 23 and the base end side of the first arm member 14R. The first right-rotating boss 32R is a component in which a small-diameter cylinder member is provided on the outside and a disc-shaped cylinder member is provided on the inside. The cylinder member on the outside is provided in an eccentric and inclined state relative to the rotation drive shaft 23. An outer cam surface 35 is formed in a circumferential manner on the outer peripheral surface of the cylinder member on the outside.

[0231] That is, the outer cam surface 35 circles around the axis of the rotation drive shaft 23 in a state that is eccentric and inclined relative to the axis direction of the rotation drive shaft 23. Since the first right annular fitting portion 33R is slidably fitted on the outer cam surface 35 from the outside, the first arm member 14R can swing (rotate) relative to the rotation drive shaft 23. When the rotation drive shaft 23 is rotated, the outer cam surface 35 draws a circular orbit that is eccentric relative to the axis of the rotation drive shaft 23 and swings left and right.

[0232] Furthermore, in the present embodiment, a small-diameter tubular member is provided inside the disc-shaped tubular member constituting the first right-rotating boss portion 32R. An inner cam surface 36 is formed in a circumferential manner on the outer peripheral surface of the inner tubular member.

[0233] That is, the inner cam surface 36 circles around the axis of the rotating drive shaft 23 in an eccentric state with respect to the axis direction of the rotating drive shaft 23. Since the slider 42R described later is slidably engaged with the inner cam surface 36 from the outside, the second arm member 14R can move forward and backward in the front-back direction with respect to the rotating drive shaft 23. When the rotating drive shaft 23 is rotated, the inner cam surface 36 describes a circular orbit eccentric with respect to the axis of the rotating drive shaft 23.

[0234] A first right annular fitting portion 33R is provided on the base end side of the first arm member 14R. The first right annular fitting portion 33R is formed so as to be fitted on the outer cam surface 35 of the first right-rotating boss portion 32R from the outside. The first arm member 14R rotates around the axis of the first right-rotating boss portion 32R by fitting the first right annular fitting portion 33R on the first right-rotating boss portion 32R (outer cam surface 35).

[0235] The first right restricting portion 34R of the present embodiment is composed of the ball joint portion 27, the connecting shaft 28, and the rotating shaft 29 that constitute the tapping massage mechanism. The connecting shaft 28 is rotatably connected to the ball joint portion 27 at the front end and is constrained by the rotating shaft 29 at the base end. With this structure, the first right restricting portion 34R restricts the first arm member 14R from rotating together with the rotating drive shaft 23.

[0236] like Fig.10 As shown, a second arm member 16R (grabbing arm member 16R) for applying a grabbing massage action to the shoulder is provided inside the first arm member 14R on the right side. The second arm member 16R is provided so as to extend forward (toward the shoulder side) from the back massage mechanism 5 side.

[0237] The second arm member 16R is a flat plate-shaped member, and a through hole 37 whose axis is oriented in the left-right direction is provided at the base end. A restriction pin 44 constituting a second right restriction portion 41R described later is inserted through the through hole 37 .

[0238] A second treatment member 17R (upper treatment member 17R) capable of performing a grabbing and kneading massage on the shoulder is provided at the front end of the second arm member 16R. The second treatment member 17R is a member formed in a shape of a horizontally placed cylinder.

[0239] The second treatment member 17R is disposed at a position opposite to the first treatment member 15R in the vertical direction. The second treatment member 17R moves toward and away from the first treatment member 15R in the vertical and front-to-back directions relative to the first treatment member 15R swinging in the left-right direction. That is, the second treatment member 17R performs a pinching massage on the center of the right shoulder by moving the second arm member 16R forward and backward in the vertical and front-to-back directions by the rotational driving force of the rotation driving shaft 23.

[0240] In addition, if Fig.10 As shown in FIG. 1 , a guide groove portion 38R for guiding a slider 42R described later is formed in the longitudinal midway portion of the second arm member 16R. The guide groove portion 38R is formed as a substantially rectangular hole in a side view that opens in the left-right direction.

[0241] The guide groove 38R allows the second arm member 16R to move forward and backward in the up-down and front-back directions. The guide groove 38R of the present embodiment is formed as a rectangular space. A slider 42R is embedded in the guide groove 38R so as to slide back and forth freely inside. That is, the rotation drive shaft 23 is provided in a through-state at the base end (guide groove 38R) of the second arm member 16R via the slider 42R.

[0242] Furthermore, a second conversion unit 39 is provided on the base end side of the second arm member 16 to convert the rotational driving force into an up-down and forward-backward motion and transmit the same to the second arm member 16. The second conversion unit 39 is composed of a second right conversion unit 39R that converts the rotational driving force into an up-down and forward-backward motion of the second arm member 16R on the right side, and a second left conversion unit 39L that converts the rotational driving force into an up-down and forward-backward motion of the second arm member 16L on the left side.

[0243] The second right conversion portion 39R has a first right rotating protrusion 32R (inner cam surface 36) installed on the rotating drive shaft 23 and rotating integrally with the rotating drive shaft 23, a second right annular fitting portion 40R arranged at the base end of the second arm component 16R and externally embedded in the inner cam surface 36 of the first right rotating protrusion 32R, and a second right limiting portion 41R limiting the second arm component 16R from rotating together with the rotating drive shaft 23.

[0244] In addition, since the second left conversion unit 39L has a structure that is a mirror-inverted structure of the second right conversion unit 39R, its description is omitted.

[0245] like Fig.10 As shown, the slider 42R is a thin plate, and is provided in a pair on the left and right sides so as to sandwich the guide groove portion 38R of the second arm member 16R. The end of the slider 42R that becomes the outer side of the second arm member 16R is provided in a flange shape. In addition, the slider 42R has a side wall surface 43 that abuts against the long edge (long side) provided in the guide groove portion 38R.

[0246] A circular through hole 40R opening in the left-right direction is formed at the center of the slider 38R. The through hole 40R is provided as a second right annular fitting portion 40R fitted into the inner cam surface 36 of the first right rotation boss 32R.

[0247] That is, the slider 42R is inserted so that the side wall surface 43 slidably contacts the long edge of the guide groove portion 38R, and the flange portion contacts the second arm member 16R, and the inner cam surface 36 of the first right rotation boss portion 32R is slidably fitted into the second right annular fitting portion 40R. When the slider 42R moves in the guide groove portion 38R by sliding along the long side of the guide groove portion 38R with the side wall surface 43, the second arm member 16R moves forward and backward in the up-and-down and front-and-back directions.

[0248] The second right restricting portion 41R includes a restricting pin 44 for restricting the swing direction of the second arm member 16R, a through hole 37 through which the restricting pin 44 passes, and a restricting hole into which the restricting pin 44 is inserted.

[0249] The limiting pin 44 passes through the through hole 37 provided at the base end of the second arm member 16R and is inserted into the limiting hole provided in the gear box 28. The second arm member 16R is connected to the main body side of the back massage mechanism 5 and becomes freely rotatable around the axis of the limiting pin 44, thereby limiting the rotation thereof with the rotating drive shaft 23.

[0250] Here, the left massage part 24L is briefly described. The left massage part 24L includes a first arm part 14L (kneading arm part 14L) for kneading the upper left side of the shoulder and a second arm part 16L (grasping arm part 16L) for grasping and pinching the lower left side of the shoulder. A first treatment member 15L is provided at the front end of the first arm part 14L. A second treatment member 17L is provided at the front end of the second arm part 16L.

[0251] In addition, if Fig.10 As shown, the back massage mechanism 5 of the present embodiment is provided with a switching portion 26 capable of switching the phase of the sandwiching action of the left and right massage portions 24, that is, two sandwiching (grabbing and kneading) actions.

[0252] like Fig.11 , Fig.12 As shown in the figures, the switching unit 26 is capable of switching: "the first clamping action", which causes the clamping action of the first treatment member 15R and the second treatment member 17R on the right side to be performed with a delayed phase relative to the phase of the clamping action of the first treatment member 15L and the second treatment member 17L on the left side; and "the second clamping action", which causes the first treatment member 15L and the second treatment member 17L on the left side and the first treatment member 15R and the second treatment member 17R on the right side to be performed with the same phase.

[0253] In the present embodiment, the switch unit 26 is provided in the right conversion unit 25R, 39R. In addition, the switch unit 26 may be provided in the left conversion unit 25L, 39L of the left massage part 24L.

[0254] like Fig.10As shown, the switching part 26 of this embodiment includes a switching shaft 45 installed on the rotating drive shaft 23, a hook part 46 provided on the outer peripheral surface side of the switching shaft 45, and a hook groove part 47 into which the hook part 46 is slidably inserted. In this embodiment, the switching part 26 adopts a "half-turn clutch mechanism" which switches the phase of the pinching (grasping and kneading) action of the right massage part 24R by delaying the movement of the right massage part 24R after the switching shaft 45 provided on the rotating drive shaft 23 rotates half a turn in the forward rotation direction or half a turn in the reverse rotation direction. However, the "half-turn clutch mechanism 26" also includes other than half a turn (180°).

[0255] The switching shaft 45 is a cylindrical member, and is installed so as to cover the rotation drive shaft 23. The switching shaft 45 rotates together with the rotation drive shaft 23. In addition, the switching shaft 45 rotates half a circle in the forward rotation direction or the reverse rotation direction together with the rotation drive shaft 23, and then rotates the first right rotation boss 32R. A hook portion 46 is formed on the outer periphery of the switching shaft 45 and protrudes outward in the radial direction.

[0256] The hook 46 of this embodiment is provided along the outer circumference of the switching shaft 45 and is a plate-like member that is long in the axial direction of the switching shaft 45 (rotation drive shaft 23). That is, the hook 46 can be said to be a curved protrusion along the hook groove 47 described later.

[0257] like Fig.10 As shown, the hook portion 46 is a curved member having a side wall having the same arc as the outer peripheral curved surface of the switching shaft 45 and two terminal walls 48 and 49. The first terminal wall 48 is a first engaging surface 48 that engages with the first rotation switching portion 50 of the hook groove portion 47 during the forward rotation of the rotation drive shaft 23. The second terminal wall 49 is a second engaging surface 49 that engages with the second rotation switching portion 51 of the hook groove portion 47 during the reverse rotation of the rotation drive shaft 23.

[0258] That is, the hook 46 is shaped to fit into the hook groove 47, and has a length (height) in the front-rear direction substantially the same as that of the hook groove 47. The hook 46 slides in the hook groove 47 around the axis of the switching shaft 45 (rotation drive shaft 23).

[0259] The hook groove 47 of this embodiment is a groove having a crescent-shaped (C-shaped) track surrounding the outer periphery of the switching shaft 45 (rotation drive shaft 23) in a side cross-sectional view. The hook groove 52 is provided along the outer periphery of the switching shaft 53 and is a groove long (deep) in the axial direction of the switching shaft 45 (rotation drive shaft 23).

[0260] That is, the hook groove 47 is a curved groove formed in the same arc as the outer peripheral curved surface of the hook 46. In addition, the hook groove 47 is a curved groove along the hook 46. That is, the hook groove 47 is a shape into which the hook 46 is embedded, and the length (depth) in the front-rear direction is substantially the same as the height of the hook 46.

[0261] The hook groove 47 is an arc-shaped groove surrounding the outer circumference of the switching shaft 45 and forms a track having two end walls. The two end walls, namely, the side walls 50 and 51 are provided as rotation switching parts 50 and 51 for switching the rotation of the rotation drive shaft 23 .

[0262] When the rotation drive shaft 23 rotates forward or reversely, the rotation switching parts 50 and 51 engage the hook part 46 that has rotated half a circle, thereby delaying the operation of the right conversion parts 25R and 39R and switching the sandwiching operation of the right massage part 24R.

[0263] In the present embodiment, the terminal end of one side of the semicircular hook groove portion 47 is the first rotation switching portion 50. The first rotation switching portion 50 is a portion for delaying the movement of the first right conversion portion 25R and the second right conversion portion 39R relative to the movement of the first left conversion portion 25L and the second left conversion portion 39L during the positive rotation of the rotation drive shaft 23.

[0264] That is, during the positive rotation of the rotating drive shaft 23, after the hook portion 46 of the switching shaft 45 rotates half a circle in the positive rotation direction around the axis of the rotating drive shaft 23, the first engaging surface 48 of the hook portion 46 is engaged with the first rotation switching portion 50, whereby the first right rotating protrusion 32R starts to rotate with a delay of half a circle relative to the rotation of the first left rotating protrusion, so that the movement of the first right conversion portion 25R and the second right conversion portion 39R is delayed relative to the movement of the first left conversion portion 25L and the second left conversion portion 39L, and the right massage portion 24R is switched to the "first clamping action".

[0265] like Fig.11 , Fig.12 As shown in the figure, if the rotation drive shaft 23 performs "positive rotation (rotation backward, upward, and forward)", the "first pinching action" of grabbing, kneading, and massaging alternately on the left and right is performed. During the "first pinching action", the left and right first treatment members 15L, 15R and the second treatment members 17L, 17R alternately perform grabbing, kneading, and massaging on the left and right shoulders (treatment parts) of the user U.

[0266] In detail, the switching unit 26 switches to the first clamping action by the positive rotation of the rotation drive shaft 23. During the half-turn rotation in the positive rotation direction around the axis of the rotation drive shaft 23, the movement of the right massage component 24R is temporarily stopped. If the first engaging surface 48 of the hook 46 is engaged with the first rotation switching unit 50 in the hook groove 47 after the switching shaft 45 rotates half a turn, the massage component 24R in the temporarily stopped state starts to move (delayed action). The switching unit 26 switches the right massage part 24R to a phase of the clamping action delayed relative to the phase of the clamping action of the left massage part 24L, and performs the first clamping action (alternating left and right grabbing, kneading and pressing massage).

[0267] The other terminal end of the semicircular hook groove 47 is the second rotation switching portion 51. The second rotation switching portion 51 is a portion for synchronizing the operation of the first right conversion portion 25R and the second right conversion portion 39R with the first left conversion portion 25L and the second left conversion portion 39L when the rotation drive shaft 23 rotates in reverse.

[0268] That is, when the rotating drive shaft 23 rotates in the reverse direction, after the hook portion 46 of the switching shaft 45 rotates half a circle in the reverse rotation direction around the axis of the rotating drive shaft 23, the second engaging surface 49 of the hook portion 46 is engaged with the second rotation switching portion 51, thereby the first right rotating protrusion 32R starts to rotate together with the first left rotating protrusion, so that the first right conversion portion 25R and the second right conversion portion 39R match the action of the first left conversion portion 25L and the second left conversion portion 39L, and the right massage portion 24R is switched to the "second clamping action".

[0269] like Fig.11 , Fig.12 As shown in the figure, if the rotation drive shaft 23 is "reversely rotated (rotated forward, upward, and backward)", the "second pinching action" of grasping, kneading, and massaging the left and right shoulders simultaneously is performed. During the "second pinching action", the left and right first treatment members 15L, 15R and the second treatment members 17L, 17R grasp, knead, and massage the left and right shoulders (treatment parts) of the user U simultaneously.

[0270] In detail, the switching unit 26 switches to the second pinching action by the reverse rotation of the rotation drive shaft 23. During the half-turn rotation in the reverse rotation direction around the axis of the rotation drive shaft 23, the movement of the right massage component 24R is temporarily stopped. If the second engagement surface 49 of the hook 46 is engaged with the second rotation switching unit 51 in the hook groove 47 after the switching shaft 45 rotates half a turn, the right massage component 24R in the temporarily stopped state starts to move (delayed action). The switching unit 26 switches the phases of the pinching action of the right massage part 24R and the left massage part 24L to the same phase, and performs the second pinching action (grasping, kneading, and pressing massage on both sides simultaneously).

[0271] That is, the switching part 26 can also be said to be a delay mechanism which makes the time point at which the first treatment piece 15R and the second treatment piece 17R on the right side (right massage part 24R) are clamped different from the time point at which the first treatment piece 15L and the second treatment piece 17L on the left side (left massage part 24L) are clamped, and by staggering the time points, grasping, kneading and pressing massage can be performed alternately left and right.

[0272] As described above, the back massage mechanism 5 of this embodiment can effectively perform grabbing and kneading massage and relieve stiffness of the treatment parts such as shoulders because it can switch between the "first pinching action" of grabbing and kneading the shoulders alternately on the left and right and the "second pinching action" of grabbing and kneading the shoulders simultaneously on the left and right with the help of the switching unit 26.

[0273] Furthermore, in the present embodiment, the chair-type massage machine 1 controls the coordinated action of the alternately left-right grabbing and kneading massage of the shoulders by the back massage mechanism 5 and the pressing action of the buttocks, legs, upper arms, back, etc. by the air bags A to H through the control unit, such as "Collaborative Massage 1" to "Collaborative Massage 7", so that the treatment area including the shoulders can be pressed more strongly or the shoulders can be grabbed and stretched at the same time, thereby relieving the stiffness of the treatment area such as the shoulders.

[0274] [Modifications]

[0275] In the chair-type massage machine 1 of the present invention described above, an embodiment in which the pressing massage mechanism is composed of one or more airbags is described in detail and specifically. That is, the cooperative actions "cooperative massage 1" to "cooperative massage 7" of the back massage mechanism 5 and the airbags A to H are described in detail. Furthermore, the modified examples of "cooperative massage 1" to "cooperative massage 4" are also described in detail. The modified examples are summarized as follows.

[0276] In this modification, the pressing massage mechanism, in particular, the pressing massage mechanism provided on the upper surface of the seat 2, may also be a mechanical massage mechanism having a pair of massage components provided on the left and right sides and performing a swinging motion, and a treatment member provided at the front end of the massage component. The massage component may be a component that performs an eccentric motion or a swinging motion. In addition, the massage component may also be a component that performs a massage action alternately on the left and right sides.

[0277] For example, the massage action of the back massage mechanism 5 of this embodiment may be that the first treatment member 15R provided at the front end of the first arm member 14R on the right side and the second treatment member 17R provided at the front end of the second arm member 16R on the right side move closer to and away from each other in the vertical direction, and perform a pinching massage on the right shoulder. In addition, the first treatment member 15R and the second treatment member 17R may also perform a swinging motion that draws a circular trajectory.

[0278] In addition, the first treatment member 15L provided at the front end of the first arm member 14L on the left side and the second treatment member 17L provided at the front end of the second arm member 16L on the left side may be moved closer and further away from each other in the vertical direction to perform a grasping, kneading and pressing massage on the left shoulder. In addition, the first treatment member 15L and the second treatment member 17L may also perform a swinging motion that draws a circular trajectory.

[0279] In this way, the back massage mechanism 5 causes the left and right first arm parts 14R, 14L and the second arm parts 16R, 16L to swing in a circular motion up and down and left and right, and alternately or simultaneously moves the first treatment piece 15R and the second treatment piece 17R on the right side arranged vertically closer to and away from each other, and the first treatment piece 15L and the second treatment piece 17L on the left side arranged vertically closer to and away from each other.

[0280] In addition, for example, the left and right first treatment members 15R, 15L and the left and right second treatment members 17R, 17L may also perform tapping massage.

[0281] The mechanical massage mechanism has a driving source composed of an electric motor or the like and a rotating shaft that rotates with the driving source. A pair of left and right massage components are eccentrically arranged or arranged via an inclined cam on the rotating shaft. In addition, the mechanical massage mechanism can move in the front-rear direction inside the seat 2.

[0282] When a pair of left and right massage components are eccentrically arranged, since the massage components (in other words, the arm components) move forward and backward in the upper direction relative to the upper surface of the seat 2, the treatment member installed at the front end of the massage component pushes the user's buttocks upward. In addition, when pushing the buttocks upward, the left and right treatment members can also push the left and right buttocks upward alternately. Therefore, in "cooperative massage 1" to "cooperative massage 4", the same action and effect as the airbags A to H pushing the user's buttocks upward can be achieved.

[0283] When a pair of left and right massage parts are provided via the inclined cam, the massage parts swing in an undulating manner, and the treatment element moves in a circular manner, for example, to move closer and further away. Therefore, the treatment element installed at the front end of the massage part has an upward movement component, pushing the user's buttocks upward, and in "cooperative massage 1" to "cooperative massage 4", the same action and effect as the airbags A to H pushing the user's buttocks upward are achieved.

[0284] In addition, in the chair-type massage machine 1 of the present invention, if the mechanical massage mechanism is positioned at the position of the airbags G and H, that is, the backrest 3 is equipped with two mechanical massage mechanisms, which is a so-called dual mechanical type, then by grasping the shoulders with the back massage mechanism 5 and moving the massage parts of the lower massage mechanism of the dual mechanical type forward, the user's back is pressed forward, thereby achieving "collaborative massage 5" and "collaborative massage 6".

[0285] That is, the chair-type massage machine 1 of the present invention controls the cooperative action of "the action of alternately pinching and kneading the shoulders (treatment part) left and right by the back massage mechanism 5" and "the action of pressing massage by the mechanical massage mechanism (first pressing mechanism), the side kneading mechanism 19 (third pressing mechanism), and the back kneading mechanism 20 (second pressing mechanism)" through the control unit, so that a cooperative massage such as pressing the treatment part including the shoulder more strongly or pinching and stretching the shoulder can be performed, and stretching therapy for the body can be performed to relieve the stiffness of the treatment part such as the shoulder without causing discomfort.

[0286] In addition, the embodiments disclosed herein are to be considered as illustrative and non-restrictive in all aspects. In particular, in the embodiments disclosed herein, matters not explicitly stated, such as operating conditions, operation conditions, dimensions and weights of components, etc., do not deviate from the scope of ordinary practice by those skilled in the art, and are matters that can be easily conceived by those skilled in the art.

[0287] For example, the control by the control unit of the above-described detailed description of the coordinated action of the massage mechanism 5 for the back to alternately grasp, knead and massage the shoulders (treatment area) left and right and the expansion and contraction of multiple air bags A to H to perform pressing actions on the buttocks, legs, upper arms, back, etc., namely [Cooperative Massage 1] to [Cooperative Massage 7], is an example and is not limited to this example and can be appropriately changed depending on the scope of treatment.

[0288] In addition, the lengths of the first arm member 14 and the second arm member 16 of the back massage mechanism 5, the inclination angle of the kneading arm member 14 relative to the rotating drive shaft 23, the separation distance between the first arm member 14 and the second arm member 16 on the left and right, etc. can be appropriately changed in consideration of the treatment range.
