[Technical field]

[0001] The present invention relates to a technique for controlling a massage action performed by a chair-type massage machine. [Background technology]

[0002] A massage device that performs the gripping and kneading function as shown in Patent Document 1 is well known, and a massage device capable of this gripping and kneading function that is installed inside the backrest of a chair-type massage machine is also commercially available. In addition, chair-type massage machines that have airbags that function as a massage mechanism on the top surface or sides of the seat on which the user sits, or on the sides of the backrest are also commercially available (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-029772 A [Patent Document 2] JP 2010-162071 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in recent years, many requests have been made by users. For example, even for chair-type massage machines that can grip and massage, there have been requests to be able to "press the treatment area more firmly when gripping and kneading the treatment area such as the shoulders, so as to press the treatment area deeper (to make the gripping and kneading deeper) to relieve stiffness," and "massage that includes a stretching motion that grips and stretches the treatment area." There have also been requests to be able to adjust the strength of pressure on the treatment area.

[0005] Therefore, in consideration of the above problems, the present invention aims to provide a chair-type massage machine that is equipped with a configuration that allows the treatment area to be pressed more firmly or to be grasped and stretched, thereby relieving stiffness in the treatment area, such as the shoulders, without causing discomfort. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a chair type massage machine according to the present invention will be described with reference to the drawings.

[0025] The embodiment described below is an example of the present invention, and the configuration of the present invention is not limited to this specific example. In addition, in order to make the drawings easier to understand, some of the components are omitted and drawn using virtual lines.

[0026] The directions of the chair type massage machine 1, such as front, back, left and right, are as shown in the drawings. These directions correspond to the directions seen by a user seated on the chair type massage machine 1. In the following description, the directions shown in the drawings are the directions when describing the chair type massage machine 1 of the present invention.

[0027] FIG. 1 shows an example of a chair-type massage machine 1 according to the present invention.

[0028] As shown in FIG. 1, the chair-type massage machine 1 of this embodiment has 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.

[0029] The chair-type massage machine 1 of this embodiment includes a back massage mechanism 5 that performs a gripping and kneading massage on the treatment area (such as the shoulders and back) of the user U, and a pressure massage mechanism that performs a pressure massage on the treatment area (such as the sides of the shoulders, the sides of the upper arms, the buttocks, and the thighs) of the user U. and a control unit that coordinates the gripping massage by the back massage mechanism 5 and the pressing action by the pressing massage mechanism.

[0030] The pressure massage mechanism includes a first pressure means for pressing upward against the buttocks and thighs of the user U, a second pressure means for pressing forward against the upper body of the user U, and a third pressure means for pressing inwardly from the side against the upper body of the user U.

[0031] The first pressing means to the third pressing means may each be provided with one or more airbags. In this embodiment, an airbag will be taken as an example for detailed explanation.

[0032] The pressure massage mechanism is equipped with one or more airbags as the first pressure means to the third pressure means. At least one or more airbags A to D of the first pressure means are arranged on the upper surface of the seat 2 and on the left and right sides of the seat 2. At least one or more airbags G and H of the second pressure means are arranged on the front surface of the backrest 3. At least one or more airbags E and F of the third pressure means are arranged on the left and right sides of the backrest 3.

[0033] The pressure massage mechanism may be an airbag, but the present invention can also be realized with a mechanical massage mechanism (not shown) as the first pressure means. This mechanical massage mechanism is disposed inside the seat 2.

[0034] The footrest 4 is provided with a pair of left and right insertion recesses 6L, 6R into which the feet (lower legs) of the user U from below the knees can be inserted separately. A foot massaging mechanism 7 that massages the lower legs, which are one of the treatment areas, is built into the left and right insertion recesses 6L, 6R. The foot massaging mechanism 7 can be, for example, a massaging plate that presses against the lower legs of the user U from the left and right, or an airbag. The footrest 4 may be stored below the seat 2 by a footrest moving mechanism 8.

[0035] A frame 9 is provided under the seat 2 for placing the chair-type massage machine 1 on the floor. The frame 9 is formed by combining several steel beams into a tower shape. The seat 2 is supported at a predetermined height by the frame 9.

[0036] The seat 2 is wide enough to support the buttocks of the user U from below. The inside of the seat 2 is filled with cushioning material, making it comfortable to sit on. The outside of the seat 2 is covered with, for example, cloth. The surface (upper surface) of the seat 2 is comfortable to touch when sitting on it.

[0037] In this embodiment, two airbags A and B (first pressing means) 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), constituting a seat massage mechanism 10 (buttocks massage mechanism 10). Airbag A is arranged on the right side of the seat 2, and applies a pressure massage to the right buttocks to the back of the right thigh of the user U. Airbag B is arranged on the left side of the seat 2, and applies a pressure massage to the left buttocks to the back of the left thigh of the user U. That is, airbags A and B are arranged in pairs on the upper surface of the seat 2.

[0038] The seat massage mechanism 10 supplies air from an air compressor to two left and right airbags A and B, and causes the left and right airbags A and B to repeatedly inflate and deflate at a predetermined rhythm, thereby providing a pressure massage from below to above the buttocks, which are one of the treatment areas. The inflation operation of the two left and right airbags A and B will be described in detail later.

[0039] Furthermore, in this embodiment, armrests 11L, 11R on which the forearms can be placed are provided on both the left and right sides of the seat 2. Two airbags C, D (first pressing means) are arranged in the left and right direction on the inner surfaces of the armrests 11L, 11R facing each other, forming a thigh massage mechanism 12. Also, in this embodiment, arm massage mechanisms 13 are provided inside the left and right armrests 11L, 11R, respectively.

[0040] Airbag C is disposed between the left side surface of the right armrest 11R and the right side of the seat 2, and provides a pressure massage to the right thigh of the user U. Airbag D is disposed between the right side surface of the left armrest 11L and the left side of the seat 2, and provides a pressure massage to the left thigh of the user U. In other words, the two airbags C and D are arranged in pairs on the left and right sides of the seat 2, separated by the width of the seat 2.

[0041] The thigh massage mechanism 12 is configured such that air is supplied from an air compressor to the two left and right airbags C and D, and the left and right airbags C and D are repeatedly inflated and deflated at a predetermined rhythm. Then, a pressure massage is performed on the thighs, which are one of the treatment areas, by pressing from the outside to the inside. The inflation operation of the two airbags C and D on the left and right will be described in detail later.

[0042] The lower end of the backrest 3 is pivoted to the rear of the seat 2, and is held in a state in which it can swing back and forth freely. The backrest 3 can be reclined relative to the seat 2 by a reclining mechanism composed of a linear actuator disposed within a frame 9. Inside the backrest 3, there is provided a back massage mechanism 5 that can alternately grab and massage the left and right sides.

[0043] The back massage mechanism 5 has a pair of first arm members 14 (kneading arm members 14) on the left and right with first treatment elements 15 at their tips, and a pair of second arm members 16 (grabbing arm members 16) on the left and right with second treatment elements 17 at their tips, and is configured to be able to perform a "grabbing and kneading massage" in which the left and right shoulders (treatment areas) are alternately grasped and kneaded by moving the first treatment elements 15 and the second treatment elements 17 toward and away from each other. The detailed structure of the back massage mechanism 5 will be described later.

[0044] Furthermore, in this embodiment, side plates 18L, 18R are provided on both the left and right sides of the backrest 3. These side plates 18L, 18R are flat plates that cover the upper body of the user U from the sides. Two airbags E, F (third pressing means) are arranged in the left and right directions inside the side plates 18L, 18R, constituting a side massaging mechanism 19.

[0045] Airbag E is disposed on the right side of the backrest 3, and performs a pressure massage on the side of the right shoulder to the side of the right upper arm of the user U. Airbag F is disposed on the left side of the backrest 3, and performs a pressure massage on the side of the left shoulder to the side of the left upper arm of the user U. In other words, the two airbags E and F are arranged in pairs on the left and right sides of the backrest 3, separated by the width of the backrest 3.

[0046] The side massaging mechanism 19 supplies air from an air compressor to the two left and right airbags E and F, and causes the left and right airbags E and F to repeatedly inflate and deflate at a predetermined rhythm, thereby applying a pressure massage to the sides of the shoulders to the sides of the upper arms, which are one of the treatment areas, from the left and right. The inflation operation of the two left and right airbags E and F will be described in detail later.

[0047] In this embodiment, two airbags G, H (second pressing means) are arranged on the left and right sides behind the front surface of the backrest 3 to form a back massage mechanism 20. The airbag G is arranged on the right side of the front surface of the backrest 3, and performs a pressure massage on the right side of the back of the user U by pressing from the rear to the front. The airbag H is arranged on the left side of the front surface of the backrest 3, and performs a pressure massage on the left side of the back of the user U by pressing from the rear to the front. That is, the airbags G, H are arranged in pairs on the front surface of the backrest 3.

[0048] The back massaging mechanism 20 supplies air from an air compressor to the two left and right airbags G, H, and causes the left and right airbags G, H to repeatedly inflate and deflate at a predetermined rhythm, thereby providing a pressure massage that pushes the back, which is one of the treatment areas, from the rear to the front. The inflation operation of the two left and right airbags G, H will be described in detail later.

[0049] In this way, the chair-type massage machine 1 of this embodiment has multiple massage sections (back massage mechanism 5, seat massage mechanism 10, thigh massage mechanism 12, side massage mechanism 19, back massage mechanism 20, foot massage mechanism 7, etc.) that massage various treatment areas.

[0050] In this embodiment, the chair type massage machine 1 can apply stronger pressure to the shoulders (treatment areas) and stretch them while grabbing them. Such pressure massage can be achieved by operating the back massage mechanism 5 and the airbags A to H in cooperation with each other.

[0051] The chair type massage machine 1 of the present invention is provided with a control unit that controls the driving of the back massage mechanism 5 and the inflation and deflation of the airbags A to H. The present invention is characterized in that the control unit can coordinate the action of the back massage mechanism 5 alternately gripping and massaging the left and right shoulders (treatment area) and the action of pressing the buttocks, thighs, upper arms, back, etc. by inflating and deflating the multiple airbags A to H.

[0052] Hereinafter, with reference to Figs. 2A to 9, the back massage mechanism 5 and the plurality of airbags The pressure massage action (grabbing massage) by the cooperative action of A to H will be described. These pressure massage actions are controlled and realized by a control unit built in the chair type massage machine 1. In this embodiment, the pressure massage actions of [Cooperative massage 1] to [Cooperative massage 7] will be described in detail. [Collaborative Massage 1] FIG. 2A is a front view showing a schematic outline of an example of a gripping and kneading massage action (cooperative massage 1) that can be controlled by a control unit provided in the chair-type massage machine 1. FIG.

[0053] As shown in FIG. 2A, the control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder of the user U, while separating the first treatment element 15L and the second treatment element 17L on the left side, and inflates the airbag A arranged on the right side of the upper surface of the seat 2 and / or the airbag C (first pressing means) arranged on the right side of the seat 2, thereby performing a "collaborative massage 1" that increases the treatment intensity on the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side.

[0054] Specifically, the back massage mechanism 5 in the backrest 3 is moved so that the first and second treatment elements 15R, 15L and 17R, 17L on the left and right are positioned to grip the left and right shoulders. The back massage mechanism 5 is driven to move the first and second treatment elements 15R, 17R on the right toward and away from each other, and then the first and second treatment elements 15L, 17L on the left are moved toward and away from each other to perform a "grasp and massage massage" in which the left and right shoulders are alternately gripped and massaged repeatedly. At this point, the user U operates the controller of the chair-type massage machine 1 to give the control unit an instruction for "collaborative massage 1".

[0055] Upon receiving the command for "Collaborative Massage 1," the control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder (the right shoulder is in a held state, as shown by the bold line in Figure 2A), while at the same time moving the first treatment element 15L and the second treatment element 17L on the left side away from each other to an open state (the left shoulder is free).

[0056] Here, with the first massage element 15R and the second massage element 17R on the right side gripping the right shoulder, the control unit inflates at least one of the airbag A (seat massage mechanism 10) or the airbag C (thigh massage mechanism 12) on the right side of the plane of the seat 2, as shown by the bold line in Figure 2A.

[0057] That is, the first massaging element 15R and the second massaging element 17R on the upper right side grip the right shoulder, and then the airbag A and / or airbag B on the lower right side are inflated (the vertical mechanism from the upper right to the lower right).

[0058] As a result, the right side of the user U's upper body is pushed upward, and the first treatment element 15R and the second treatment element 17R pinpoint-dig into (penetrate) the right shoulder, which is the target treatment area, thereby providing a stronger and more effective pressure massage to the right shoulder.

[0059] In other words, when the airbag A and / or the airbag C inflate, the user is lifted upward, and the first treatment element 15R and the second treatment element 17R on the right side locally press the right shoulder (acupoint pressing state).

[0060] Furthermore, even if the first treatment element 15R and the second treatment element 17R on the right side are pressed against the right shoulder of the user with excessive force, the airbag A can be depressed downward, so that the acupressure pressure state is hardly felt as "painful" and a comfortable local pressure massage can be achieved. [Variation 1 of Collaborative Massage 1] Here, we will explain the modified example 1 of the cooperative massage 1. That is, we will explain the case where, in the cooperative massage 1, the right shoulder is gripped by the first massage element 15R and the second massage element 17R on the right side, and either of the airbags E and F arranged on the left and right sides of the backrest 3 is inflated. [Case 1] FIG. 2B shows an outline of Example 1 of Variation 1 of the cooperative massage 1, that is, when the right shoulder is grasped by the first massage element 15R and the second massage element 17R on the right side and the airbag F on the left side of the backrest 3 is inflated.

[0061] As shown in FIG. 2B, in the pressure massage mechanism of this modification, the control unit controls the first treatment element on the right side. The first treatment element 15R and the second treatment element 17R are brought close to each other to grasp the right shoulder of the user U, while the first treatment element 15L and the second treatment element 17L on the left side are separated, and the airbag F arranged on the left side of the backrest portion 3 is inflated, thereby increasing the strength of the treatment applied to the grasped right shoulder.

[0062] Specifically, the first and second treatment elements 15R and 17R on the right side are brought close to each other to grip the right shoulder of the user U, while the first and second treatment elements 15L and 17L on the left side are separated from each other. The right shoulder is held by the grip of the first and second treatment elements 15R and 17R on the right side.

[0063] It is more preferable to inflate at least one of the airbag A (seat massage mechanism 10) arranged on the right side of the plane of the seat 2 and the airbag C (thigh massage mechanism 12) arranged on the right side of the seat 2. The body is supported by the inflation of the airbag A in the seat 2.

[0064] When the airbag F arranged on the left side of the backrest portion 3 is inflated, a load is applied from the left to the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side, so that the right shoulder is pressed more firmly, and the treatment intensity for the grasped right shoulder is increased (the right shoulder is pressed firmly to relieve stiffness). [Case 2] FIG. 2C shows an outline of Example 2 of Variation 1 of the cooperative massage 1, that is, when the right shoulder is gripped by the first massage element 15R and the second massage element 17R on the right side and the airbag E on the right side of the backrest 3 is inflated.

[0065] As shown in FIG. 2C, in the pressure massage mechanism of this modified example, the control unit brings the first and second treatment members 15R and 17R on the right side close together to grasp the right shoulder of the user U, while separating the first and second treatment members 15L and 17L on the left side, and inflates the airbag E located on the right side of the backrest portion 3, thereby increasing the strength of the treatment applied to the grasped right shoulder.

[0066] Specifically, the first and second treatment elements 15R and 17R on the right side are brought close to each other to grip the right shoulder, while the first and second treatment elements 15L and 17L on the left side are separated from each other. The right shoulder of the user U is held by the grip of the first and second treatment elements 15R and 17R on the right side.

[0067] It is more preferable to inflate at least one of the airbag A (seat massage mechanism 10) arranged on the right side of the plane of the seat 2 and the airbag C (thigh massage mechanism 12) arranged on the right side of the seat 2. The body is supported by the inflation of the airbag A in the seat 2.

[0068] When the airbag E arranged on the right side of the backrest portion 3 is inflated, the upper body moves leftward, and the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side is stretched (lateral stretching - by sliding the grasped treatment elements sideways, the right shoulder (treatment area) is stretched), and the strength of the treatment applied to the grasped right shoulder is increased. [Variation 2 of Collaborative Massage 1] Next, a second modified example of the cooperative massage 1 will be described. That is, a case where the first pressing means (pressing massage mechanism) in the cooperative massage 1 is a mechanical massage mechanism will be described.

[0069] The pressure massage mechanism of this modification is different from the above in that it is provided with a mechanical massage mechanism as the first pressure means. The mechanical massage mechanism may, for example, have a pair of massage members (arm members) on the left and right with treatment elements at their tips, which move in the front-rear direction inside the seat 2. The massage members may have eccentric motion or oscillating motion. The massage members may also perform massage actions alternately on the left and right sides.

[0070] The mechanical massage mechanism also includes a massage mechanism in which the massage applicator (massage member) moves in an arc in the front-back direction (has a component of up-down movement). In other words, the mechanical massage mechanism includes a massage mechanism in which the massage applicator moves upward when viewed from the side.

[0071] The second pressing means (airbags G and H) and the third pressing means (airbags E and F) are the same as those described above.

[0072] The first treatment element 15R and the second treatment element 17R on the right side, and the right treatment element of the right massage member (machine The basic cooperative operation with the right-side first treatment element 15R and second treatment element 17R and the right-side airbag A and / or airbag C described above will be described briefly below since it is substantially the same as the cooperative operation between the right-side first treatment element 15R and second treatment element 17R and the right-side airbag A and / or airbag C described above.

[0073] The control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder of the user U, while separating the first treatment element 15L and the second treatment element 17L on the left side, and performs "collaborative massage 1" by pressing upward against the user's right buttocks and / or right thigh with the right treatment element (first pressing means) of the right massage member arranged on the right side of the seat 2, thereby increasing the treatment intensity on the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side.

[0074] The mechanical massage mechanism in the seat 2 is moved forward and backward so that, for example, the right treatment element touches the right buttock. Then, the right treatment element lifts the right buttock, and the upper body (right side) of the user U is pushed upward, so that the first treatment element 15R and the second treatment element 17R pinpoint-dig into (penetrate into) the right shoulder, which is the target treatment area, and a strong and effective pressure massage is performed on the right shoulder. [Collaborative Massage 2] FIG. 3A is a front view showing a schematic outline of an example of a gripping and kneading massage action (cooperative massage 2) that can be controlled by a control unit provided in the chair-type massage machine 1. FIG.

[0075] As shown in FIG. 3A, the control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder of the user U, while separating the first treatment element 15R and the second treatment element 17R on the right side, and inflates the airbag B arranged on the left side of the upper surface of the seat 2 and / or the airbag D (first pressing means) arranged on the left side of the seat 2, thereby performing a "collaborative massage 2" that increases the intensity of treatment on the left shoulder grasped by the first treatment element 15L and the second treatment element 17L on the left side.

[0076] Specifically, the back massage mechanism 5 in the backrest 3 is moved so that the first and second massage applicators 15R, 15L and 17R, 17L on the left and right sides are positioned to grip the left and right shoulders. The back massage mechanism 5 is driven to move the first and second massage applicators 15L, 17L on the left side closer to and farther from each other, and the first and second massage applicators 15R, 17R on the right side closer to and farther from each other, and then, while performing the "grasp and knead massage" in which the left and right shoulders are alternately gripped and kneaded repeatedly, the user U operates the controller of the chair-type massage machine 1 and gives the control unit an instruction for "collaborative massage 2".

[0077] Upon receiving the command for "collaborative massage 2," the control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder (the left shoulder is in a held state, as shown by the bold line in Figure 3A), while at the same time moving the first treatment element 15R and the second treatment element 17R on the right side away from each other to an open state (the right shoulder is free).

[0078] Here, with the first massage element 15L and the second massage element 17L on the left side gripping the left shoulder, the control unit inflates at least one of airbag B (seat massage mechanism 10) or airbag D (thigh massage mechanism 12) on the right side of the plane of the seat 2, as shown by the bold line in Figure 3A.

[0079] That is, the first massaging element 15L and the second massaging element 17L on the upper left side grip the left shoulder, and then the airbag B and / or airbag D on the lower left side are inflated (the vertical mechanism from upper left to lower left).

[0080] As a result, the left side of the user U's upper body is pushed upward, and the first treatment element 15L and the second treatment element 17L pinpoint-dig into (penetrate) the left shoulder, which is the target treatment area, thereby providing a stronger and more effective pressure massage to the left shoulder.

[0081] In other words, when the airbag B and / or the airbag D inflate, the user is lifted upward, and the first treatment element 15L and the second treatment element 17L on the left side press locally on the left shoulder (acupoint pressing state).

[0082] Furthermore, even if the first treatment element 15L and the second treatment element 17L on the left side are pressed against the left shoulder of the user with excessive force, the airbag B can be depressed downward, so that the acupressure pressure state is hardly felt as "painful" and a comfortable local pressure massage can be achieved. [Variation 1 of Collaborative Massage 2] Here, we will explain the modified example 1 of the cooperative massage 2. That is, we will explain the case where, in the cooperative massage 2, the first massage element 15L and the second massage element 17L on the left side grip the left shoulder, and either of the airbags E and F arranged on the left and right sides of the backrest 3 is inflated. [Case 1] FIG. 3B shows an outline of Example 1 of Modification 1 of the cooperative massage 2, that is, when the airbag E on the right side of the backrest 3 is inflated while the left shoulder is gripped by the first massage element 15L and the second massage element 17L on the left side.

[0083] As shown in FIG. 3B, in the pressure massage mechanism of this modified example, the control unit brings the first and second treatment members 15L and 17L on the left side close together to grasp the left shoulder of the user U, while separating the first and second treatment members 15R and 17R on the right side, and inflates the airbag E located on the right side of the backrest portion 3, thereby increasing the intensity of treatment applied to the grasped left shoulder.

[0084] Specifically, the first and second treatment elements 15L and 17L on the left side are brought close to each other to grip the left shoulder of the user U, while the first and second treatment elements 15R and 17R on the right side are separated from each other. The left shoulder of the user U is held by the grips of the first and second treatment elements 15L and 17L on the left side.

[0085] It is more preferable to inflate at least one of the airbag B (seat massage mechanism 10) arranged on the left side of the plane of the seat 2 and the airbag D (thigh massage mechanism 12) arranged on the left side of the seat 2. The body is supported by the inflation of the airbag B of the seat 2.

[0086] When the airbag E arranged on the right side of the backrest portion 3 is inflated, a load is applied from the right direction to the left shoulder grasped by the first treatment element 15L and the second treatment element 17L on the left side, so that the shoulder is pressed more firmly, and the treatment intensity for the grasped left shoulder is increased (the left shoulder is pressed firmly to relieve stiffness). [Case 2] FIG. 3C shows an outline of Example 2 of Modification 1 of the cooperative massage 2, that is, when the airbag F on the left side of the backrest 3 is inflated while the left shoulder is gripped by the first massage element 15L and the second massage element 17L on the left side.

[0087] As shown in FIG. 3C, in the pressure massage mechanism of this modified example, the control unit brings the first and second treatment members 15L and 17L on the left side close together to grasp the left shoulder of the user U, while separating the first and second treatment members 15R and 17R on the right side, and inflates the airbag F located on the left side of the backrest portion 3, thereby increasing the strength of the treatment applied to the grasped left shoulder.

[0088] Specifically, the first and second treatment elements 15L and 17L on the left side are brought close to each other to grip the left shoulder, while the first and second treatment elements 15R and 17R on the right side are separated from each other. The left shoulder of the user U is held by the grips of the first and second treatment elements 15L and 17L on the left side.

[0089] It is more preferable to inflate at least one of the airbag B (seat massage mechanism 10) arranged on the left side of the plane of the seat 2 and the airbag D (thigh massage mechanism 12) arranged on the left side of the seat 2. The body is supported by the inflation of the airbag B of the seat 2.

[0090] When the airbag F arranged on the left side of the backrest portion 3 is inflated, the upper body moves to the right, and the left shoulder grasped by the first treatment element 15L and the second treatment element 17L on the left side is stretched (lateral stretching - by sliding the grasped treatment elements sideways, the left shoulder (treatment area) is stretched), and the strength of the treatment applied to the grasped left shoulder can be increased. [Variation 2 of Collaborative Massage 2] Next, a second modified example of the cooperative massage 2 will be described. That is, a case where the first pressing means (pressing massage mechanism) in the cooperative massage 2 is a mechanical massage mechanism will be described.

[0091] The pressure massage mechanism of this modification is different from the above in that it includes a mechanical massage mechanism as the first pressure means. The mechanical massage mechanism is, for example, a massager having a treatment head at the tip. It is preferable that the seat 2 has a pair of massage members (arm members) on the left and right sides, which move in the front-rear direction inside the seat 2. It is preferable that the massage members have eccentric motion or rocking motion. The massage members may also perform massage actions alternately on the left and right sides.

[0092] The mechanical massage mechanism also includes a massage mechanism in which the massage applicator (massage member) moves in an arc in the front-back direction (has a component of up-down movement). In other words, the mechanical massage mechanism includes a massage mechanism in which the massage applicator moves upward when viewed from the side.

[0093] The second pressing means (airbags G and H) and the third pressing means (airbags E and F) are the same as those described above.

[0094] The basic cooperative operation between the first and second treatment members 15L and 17L on the left side and the left treatment member of the left massage member (mechanical massage mechanism) is approximately the same as the cooperative operation between the first and second treatment members 15L and 17L on the left side and the left airbag B and / or airbag D described above, so will only be briefly explained.

[0095] The control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder of the user U, while separating the first treatment element 15R and the second treatment element 17R on the right side, and performs a "collaborative massage 2" by pressing upward against the user's left buttocks and / or left thigh with the left treatment element (first pressing means) of the left massage member arranged on the left side of the seat 2, thereby increasing the treatment intensity on the left shoulder grasped by the first treatment element 15L and the second treatment element 17L on the left side.

[0096] The mechanical massage mechanism in the seat 2 is moved forward and backward so that, for example, the left treatment element touches the left buttock. Then, the left treatment element lifts the left buttock, and the upper body (left side) of the user U is pushed upward, so that the first treatment element 15L and the second treatment element 17L pinpoint-dig into (penetrate into) the left shoulder, which is the target treatment area, and a strong and effective pressure massage is performed on the left shoulder. [Collaborative Massage 3] FIG. 4 is a front view showing a schematic outline of an example of a gripping and kneading massage action (cooperative massage 3) that can be controlled by a control unit provided in the chair-type massage machine 1. As shown in FIG.

[0097] As shown in FIG. 4, the control unit brings the first treatment element 15R and the second treatment element 17R on the right side close to each other to grasp the right shoulder of the user U, while separating the first treatment element 15L and the second treatment element 17L on the left side, and inflates the airbag B arranged on the left side of the upper surface of the seat 2 and / or the airbag D (first pressing means) arranged on the left side of the seat 2, thereby performing a "collaborative massage 3" that stretches the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side (lateral stretching - the grasped treatment elements are slid sideways to stretch and stretch the right shoulder (treatment area)).

[0098] Specifically, the back massage mechanism 5 in the backrest 3 is moved so that the first and second treatment elements 15R, 15L and 17R, 17L on the left and right sides are positioned to grip the left and right shoulders. The back massage mechanism 5 is driven to move the first and second treatment elements 15R, 17R on the right side closer to and farther apart, and then the first and second treatment elements 15L, 17L on the left side are moved closer to and farther apart, so that the left and right shoulders are gripped and massaged alternately and repeatedly, while a "grasp and massage massage" is being performed. At this point, the user U operates the controller of the chair-type massage machine 1 and gives an instruction for "cooperative massage 3" to the control unit.

[0099] Upon receiving the command for "Collaborative Massage 3," the control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder (the right shoulder is in a held state, as shown by the bold line in Figure 4), while at the same time moving the first treatment element 15L and the second treatment element 17L on the left side away from each other to an open state (the left shoulder is free).

[0100] Here, with the first massage element 15R and the second massage element 17R on the right side gripping the right shoulder, the control unit inflates at least one of the airbag B (seat massage mechanism 10) and the airbag D (thigh massage mechanism 12) arranged on the left side of the seat 2, as shown by the bold lines in Figure 4.

[0101] That is, the first massaging element 15R and the second massaging element 17R on the upper right side grip the right shoulder, and then the airbag B and / or airbag D on the lower left side are inflated (the mechanism in the diagonal direction from upper right to lower left).

[0102] As a result, the left side of the user U's upper body is pushed upward and tilted to the right, but because the first and second treatment elements 15R, 17R on the right side are gripping the right shoulder, the first and second treatment elements 15R, 17R on the right side slide sideways while still gripping the right shoulder, stretching the right shoulder (treatment area).

[0103] In addition, the first treatment element 15R and the second treatment element 17R are pinpoint-engaged (penetrated) into the right shoulder area, so that a stronger pressure massage can be effectively performed on the right shoulder area.

[0104] In other words, when the airbag B and / or the airbag D is inflated, the user is lifted upward, and the first treatment element 15R and the second treatment element 17R on the right side locally press the right shoulder (acupoint pressing state).

[0105] Furthermore, even if the first treatment element 15R and the second treatment element 17R on the right side are pressed against the right shoulder of the user with excessive force, the airbag B can be depressed downward, so that the acupressure pressure state is hardly felt as "painful" and a comfortable local pressure massage can be achieved. [Modification of Collaborative Massage 3] Here, a modified example of the cooperative massage 3 will be described. That is, a case where the first pressing means (pressing massage mechanism) in the cooperative massage 3 is a mechanical massage mechanism will be described.

[0106] The pressure massage mechanism of this modification is different from the above in that it is provided with a mechanical massage mechanism as the first pressure means. The mechanical massage mechanism may, for example, have a pair of massage members (arm members) on the left and right with treatment elements at their tips, which move in the front-rear direction inside the seat 2. The massage members may have eccentric motion or oscillating motion. The massage members may also perform massage actions alternately on the left and right sides.

[0107] The mechanical massage mechanism also includes a massage mechanism in which the massage applicator (massage member) moves in an arc in the front-back direction (has a component of up-down movement). In other words, the mechanical massage mechanism includes a massage mechanism in which the massage applicator moves upward when viewed from the side.

[0108] The second pressing means (airbags G and H) and the third pressing means (airbags E and F) are the same as those described above.

[0109] The basic cooperative operation between the first and second treatment members 15R and 17R on the right side and the left treatment member (mechanical massage mechanism) of the left massage member is approximately the same as the cooperative operation between the first and second treatment members 15R and 17R on the right side and the airbag B and / or airbag D on the left side described above, so will only be briefly explained.

[0110] The control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder of the user U, while separating the first treatment element 15L and the second treatment element 17L on the left side, and performs a "collaborative massage 3" by pressing upward against the user's left buttocks and / or left thigh with the left treatment element (first pressing means) of the left massage member arranged on the left side of the seat 2, thereby increasing the treatment intensity on the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side.

[0111] The mechanical massage mechanism in the seat 2 is moved forward and backward so that, for example, the left massage element touches the left buttock. Then, the left buttock is lifted by the left massage element, and the left side of the upper body of the user U is pushed upward and tilted to the right, but since the first massage element 15R and the second massage element 17R on the right side are in a state of gripping the right shoulder, the first massage element 15R and the second massage element 17R on the right side slide sideways while gripping the right shoulder, stretching the right shoulder (treatment area).

[0112] In addition, the first treatment element 15R and the second treatment element 17R are pinpoint-engaged (penetrated) into the right shoulder area, so that a stronger pressure massage can be effectively performed on the right shoulder area. [Collaborative Massage 4] FIG. 5 is a front view showing a schematic outline of an example of a gripping and kneading massage action (cooperative massage 4) that can be controlled by a control unit provided in the chair-type massage machine 1. As shown in FIG.

[0113] As shown in FIG. 5, the control unit brings the first treatment element 15L and the second treatment element 17L on the left side close to each other to grip the left shoulder of the user U, while separating the first treatment element 15R and the second treatment element 17R on the right side, and inflates the airbag A arranged on the right side of the upper surface of the seat portion 2 and / or the airbag C (first pressing means) arranged on the right side of the seat portion 2 to press the first treatment element 15R on the left side. Then, a "collaborative massage 4" is performed in which the first treatment element 15L and the second treatment element 17L stretch the left shoulder area (lateral stretch: the grasped treatment element is slid sideways to stretch the left shoulder area (treatment area)).

[0114] Specifically, the back massage mechanism 5 in the backrest 3 is moved so that the first and second treatment elements 15R, 15L and 17R, 17L on the left and right sides are positioned to grip the left and right shoulders. The back massage mechanism 5 is driven to move the first and second treatment elements 15L, 17L on the left side closer to and farther apart, and then the first and second treatment elements 15R, 17R on the right side are moved closer to and farther apart to perform a "grasp and massage massage" in which the left and right shoulders are alternately gripped and massaged repeatedly. At this point, the user U operates the controller of the chair-type massage machine 1 to give the control unit an instruction for "cooperative massage 4".

[0115] Upon receiving the command for "Collaborative Massage 4," the control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder (the left shoulder is in a held state, as shown by the bold line in Figure 5), while at the same time moving the first treatment element 15R and the second treatment element 17R on the right side away from each other to an open state (the right shoulder is free).

[0116] Here, with the first massage element 15L and the second massage element 17L on the left side gripping the left shoulder, the control unit inflates at least one of the airbag A (seat massage mechanism 10) and the airbag C (thigh massage mechanism 12) arranged on the right side of the seat 2, as shown by the thick lines in Figure 5.

[0117] That is, the first massaging element 15L and the second massaging element 17L on the upper left side grip the left shoulder, and then the airbag A and / or airbag C on the lower right side are inflated (the mechanism in the diagonal direction from upper left to lower right).

[0118] As a result, the right side of the user U's upper body is pushed upward and tilted to the left, but because the first treatment element 15L and the second treatment element 17L on the left side are still gripping the left shoulder, the first treatment element 15L and the second treatment element 17L on the left side slide sideways while still gripping the left shoulder, stretching the left shoulder (treatment area).

[0119] In addition, the first treatment element 15L and the second treatment element 17L are pinpoint-engaged (penetrated) into the left shoulder area, so that a stronger pressure massage can be effectively performed on the left shoulder area.

[0120] In other words, when the airbag A and / or the airbag C inflate, the user is lifted upward, and the first treatment element 15L and the second treatment element 17L on the left side locally press the left shoulder (acupoint pressing state).

[0121] Furthermore, even if the first treatment element 15L and the second treatment element 17L on the left side are pressed against the left shoulder of the user with excessive force, the airbag A can be depressed downward, so that the acupressure pressure state is hardly felt as "painful" and a comfortable local pressure massage can be achieved. [Modification of Collaborative Massage 4] Here, a modified example of the cooperative massage 4 will be described. That is, a case where the first pressing means (pressure massage mechanism) in the cooperative massage 4 is a mechanical massage mechanism will be described.

[0122] The pressure massage mechanism of this modification is different from the above in that it is provided with a mechanical massage mechanism as the first pressure means. The mechanical massage mechanism may, for example, have a pair of massage members (arm members) on the left and right with treatment elements at their tips, which move in the front-rear direction inside the seat 2. The massage members may have eccentric motion or oscillating motion. The massage members may also perform massage actions alternately on the left and right sides.

[0123] The mechanical massage mechanism also includes a massage mechanism in which the massage applicator (massage member) moves in an arc in the front-back direction (has a component of up-down movement). In other words, the mechanical massage mechanism includes a massage mechanism in which the massage applicator moves upward when viewed from the side.

[0124] The second pressing means (airbags G and H) and the third pressing means (airbags E and F) are the same as those described above.

[0125] The basic cooperative operation between the first and second treatment elements 15L and 17L on the left side and the right treatment element (mechanical massage mechanism) of the right massage member is similar to the cooperative operation between the first and second treatment elements 15L and 17L on the left side and the airbag A and / or airbag C on the right side described above. Since they are the same, we will explain them briefly.

[0126] The control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder of the user U, while separating the first treatment element 15R and the second treatment element 17R on the right side, and performs a "collaborative massage 4" by pressing upward against the user's right buttocks and / or right thigh with the right treatment element (first pressing means) of the right massage member arranged on the right side of the seat 2, thereby increasing the treatment intensity on the left shoulder grasped by the first treatment element 15L and the second treatment element 17L on the left side.

[0127] The mechanical massage mechanism in the seat 2 is moved forward and backward so that, for example, the right massage element touches the right buttock. Then, the right buttock is lifted by the right massage element, and the right side of the upper body of the user U is pushed upward and tilted to the left, but since the first massage element 15L and the second massage element 17L on the left side are in a state of gripping the left shoulder, the first massage element 15L and the second massage element 17L on the left side slide sideways while gripping the left shoulder, stretching the left shoulder (treatment area).

[0128] In addition, the first treatment element 15L and the second treatment element 17L are pinpoint-engaged (penetrated) into the left shoulder area, so that a stronger pressure massage can be effectively performed on the left shoulder area. [Collaborative Massage 5] Fig. 6 is a front view showing an example of a gripping and kneading massage action (cooperative massage 5) that can be controlled by a control unit provided in the chair-type massage machine 1. Fig. 9 is a left side view showing an example of a gripping and kneading massage action that can be controlled by a control unit provided in the chair-type massage machine 1.

[0129] As shown in Figures 6, 9, etc., the control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder of the user U, while separating the first treatment element 15L and the second treatment element 17L on the left side, and inflates the airbag H (second pressing means) arranged on the left side of the backrest portion 3, thereby twisting the left side of the upper body of the user U and performing a "collaborative massage 5" that increases the treatment intensity on the right shoulder grasped by the first treatment element 15R and the second treatment element 17R on the right side.

[0130] Specifically, the back massage mechanism 5 in the backrest 3 is moved so that the first and second treatment elements 15R, 15L and 17R, 17L on the left and right sides are positioned to grip the left and right shoulders. The back massage mechanism 5 is driven to move the first and second treatment elements 15R, 17R on the right side closer to and farther apart, and then the first and second treatment elements 15L, 17L on the left side are moved closer to and farther apart, so that the left and right shoulders are gripped and massaged alternately and repeatedly, while a "grasp and massage massage" is being performed. At this point, the user U operates the controller of the chair-type massage machine 1 and gives an instruction for "collaborative massage 5" to the control unit.

[0131] Upon receiving the command for "collaborative massage 5," the control unit brings the first treatment element 15R and the second treatment element 17R on the right side close together to grasp the right shoulder (the right shoulder is in a held state, as shown by the bold line in Figure 6), while at the same time moving the first treatment element 15L and the second treatment element 17L on the left side away from each other to an open state (the left shoulder is free).

[0132] Here, with the first massage element 15R and the second massage element 17R on the right side gripping the right shoulder, the control unit inflates the airbag H (back massaging mechanism 20) arranged on the left side of the backrest portion 3, as shown by the thick line in Figure 6.

[0133] That is, the first massaging element 15R and the second massaging element 17R on the upper right side grip the right shoulder, and then the airbag H on the left side and approximately in the center is inflated (the diagonal mechanism from upper right to center left).

[0134] Then, the left side of the user U's back is pushed forward, causing the left side of the upper body to twist. At this time, the left side of the body is stretched. The first treatment element 15R and the second treatment element 17R on the right side slide sideways while holding the right shoulder, stretching the right shoulder (treatment area).

[0135] In addition, the first treatment element 15R and the second treatment element 17R are pinpoint-engaged (penetrated) into the right shoulder area, so that a stronger pressure massage can be effectively performed on the right shoulder area.

[0136] In other words, due to the inflation of the airbag H, the left side of the upper body of the user is pushed forward and twisted, and the first treatment element 15R and the second treatment element 17R on the right side locally press the right shoulder. (Pressing acupressure points).

[0137] Furthermore, even if the first treatment element 15R and the second treatment element 17R on the right side are pressed against the right shoulder of the user with excessive force, the airbag H can be depressed rearward, so that the acupressure pressure state is hardly felt as "painful" and a comfortable local pressure massage can be achieved. [Collaborative Massage 6] FIG. 7 is a front view showing a schematic outline of an example of a gripping and kneading massage action (cooperative massage 6) that can be controlled by a control unit provided in the chair-type massage machine 1. As shown in FIG.

[0138] As shown in Figures 7, 9, etc., the control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder of the user U, while separating the first treatment element 15R and the second treatment element 17R on the right side, and inflates the airbag G (second pressing means) arranged on the right side of the backrest portion 3, thereby twisting the right side of the upper body of the user U and performing a "collaborative massage 6" that increases the treatment intensity on the left shoulder grasped by the first treatment element 15L and the second treatment element 17L on the left side.

[0139] Specifically, the back massage mechanism 5 in the backrest 3 is moved so that the first and second massage applicators 15R, 15L and 17R, 17L on the left and right sides are positioned to grasp the left and right shoulders. The back massage mechanism 5 is driven to move the first and second massage applicators 15L, 17L on the left side closer to and farther apart, and then the first and second massage applicators 15R, 17R on the right side are moved closer to and farther apart to perform a "grasp and massage massage" in which the left and right shoulders are alternately grasped and massaged repeatedly. At this point, the user U operates the controller of the chair-type massage machine 1 to give an instruction for a "cooperative massage 6" to the control unit.

[0140] Upon receiving the command for "collaborative massage 6," the control unit brings the first treatment element 15L and the second treatment element 17L on the left side close together to grasp the left shoulder (the left shoulder is in a held state, as shown by the bold line in Figure 7), while at the same time moving the first treatment element 15R and the second treatment element 17R on the right side away from each other to an open state (the right shoulder is free).

[0141] Here, with the first massage element 15L and the second massage element 17L on the left side gripping the left shoulder, the control unit inflates the airbag G (back massaging mechanism 20) arranged on the right side of the backrest portion 3, as shown by the thick line in Figure 7.

[0142] That is, the first massaging element 15L and the second massaging element 17L on the upper left side grip the right shoulder, and then the airbag G on the right side and approximately in the center is inflated (the mechanism in the diagonal direction from the upper left to the center right).

[0143] Then, the right side of the user U's back is pushed forward, causing the right side of the upper body to twist. At this time, the right side of the body is stretched. The first treatment element 15L and the second treatment element 17L on the left side slide sideways while holding the left shoulder, stretching the left shoulder (treatment area).

[0144] In addition, the first treatment element 15L and the second treatment element 17L are pinpoint-engaged (penetrated) into the left shoulder area, so that a stronger pressure massage can be effectively performed on the left shoulder area.

[0145] In other words, when the airbag G inflates, the right side of the user's upper body is pushed forward and twisted, and the first treatment element 15L and the second treatment element 17L on the left side press locally on the left shoulder (acupoint pressing state).

[0146] Furthermore, even if the first treatment element 15L and the second treatment element 17L on the left side are pressed against the left shoulder of the user with excessive force, the airbag G can be depressed rearward, so that the acupressure pressure state is hardly felt as "painful" and a comfortable local pressure massage can be achieved. [Collaborative Massage 7] FIG. 8 is a front view showing a schematic outline of an example of a gripping and kneading massage action (cooperative massage 7) that can be controlled by a control unit provided in the chair-type massage machine 1. As shown in FIG.

[0147] As shown in FIG. 8, when the control unit uses the left and right first treatment members 15L, 15R and the left and right second treatment members 17L, 17R to alternately grasp and massage the left and right shoulders of the user U, it inflates the airbags E, F (third pressing means) provided on the left and right sides of the backrest portion 3 to perform a "cooperative massage 7" that holds the upper body of the user U.

[0148] In other words, the "cooperative massage 7" is a massage performed by a first massager 15L, 15R and a second massager 17L, 1 In 7R, the left and right swaying of the upper body that occurs when grabbing and massaging the shoulders alternately is suppressed.

[0149] Specifically, the back massage mechanism 5 is moved so that the left and right first treatment elements 15R, 15L and the right and second treatment elements 17R, 17L are positioned to grip the left and right shoulders. When the left first treatment element 15L and the left second treatment element 17L are moved toward and away from each other, and then the right first treatment element 15R and the right second treatment element 17R are moved toward and away from each other to perform a "grasp and massage" in which the left and right shoulders are alternately gripped and massaged repeatedly, the upper body of the user U leaning against the backrest 3 sways left and right due to the influence of the swinging of the left and right first arm members 14L, 14R and the left and right second arm members 16L, 16R.

[0150] In order to prevent the above-mentioned situation, the user U operates the controller of the chair-type massage machine 1 and issues a command to the control unit to perform a "cooperative massage 7." Upon receiving the command to perform a "cooperative massage 7," the control unit inflates the airbags E and F (side massaging mechanism 19) provided on the left and right sides of the backrest 3, as shown by the bold lines in FIG. 8, to support the upper body of the user U.

[0151] The back massage mechanism 5 is driven to move the first treatment element 15L and the second treatment element 17L on the left side closer to and farther away from each other, and then the first treatment element 15R and the second treatment element 17R on the right side closer to and farther away from each other, thereby performing a "grasp and knead massage" in which the left and right shoulders are alternately grasped and kneaded repeatedly.

[0152] As described above, the chair-type massage machine 1 of the present invention has a control unit that controls the "action of the back massage mechanism 5 alternately grabbing and massaging the left and right shoulders (treatment area)" and the "pressing action of the multiple airbags A to H (seat massage mechanism 10 (first pressing means), thigh massage mechanism 12 (first pressing means), side massage mechanism 19 (third pressing means), back massage mechanism 20 (second pressing means), etc.) against the buttocks, thighs, upper arms, back, etc.", so that it is possible to apply stronger pressure to the treatment areas including the shoulders and stretch the shoulders while grabbing them, as in "cooperative massage 1" to "cooperative massage 7," thereby relieving stiffness in the treatment areas such as the shoulders without causing any discomfort.

[0153] Next, the configuration of the back massage mechanism 5 of this embodiment will be described. Although various massage mechanisms can be adopted to realize the cooperative massage of the present invention, a preferred back massage mechanism 5 will be described below. Note that the embodiment of the back massage mechanism 5 described below is merely an example and does not limit the configuration of the present invention.

[0154] Fig. 10 is a perspective view showing the configuration of the back massage mechanism 5, and is a view in which the switching unit 26 is disassembled. Fig. 11 is a bottom view showing the gripping and kneading massage action by the back massage mechanism 5 (left: first clamping action (alternately gripping and kneading the left and right), right: second clamping action (simultaneous gripping and kneading the left and right)). Fig. 12 is a front view showing the gripping and kneading massage action by the back massage mechanism 5 (left: first clamping action (alternately gripping and kneading the left and right), right: second clamping action (simultaneous gripping and kneading the left and right)).

[0155] As shown in Figures 10 to 12, the back massage mechanism 5 of this embodiment can perform a "first clamping action" in which the left and right first treatment elements 15 and second treatment elements 17 alternately grasp and massage the left and right shoulders (treatment areas) of the user U, and a "second clamping action" in which the left and right first treatment elements 15 and second treatment elements 17 simultaneously grasp and massage the left and right shoulders of the user U.

[0156] Furthermore, the back massage mechanism 5 of this embodiment can be stopped in a state in which the first massage element 15 and the second massage element 17 grip either the left or right shoulder of the user U.

[0157] The back massage mechanism 5 of this embodiment includes a drive unit 22 mounted on a base 21 and generating a rotational drive force, a rotary drive shaft 23 mounted on the base 21 with its axis facing in the left-right direction and rotated by the rotational drive force, massage units 24 equipped with treatment elements 15, 17 at their tip ends and mounted in a pair on the left and right sides of the base 21, a conversion unit 25 mounted on the rotary drive shaft 23 and converting the rotational drive force into a clamping motion (oscillating motion) and transmitting it to the massage unit 24, and a switching unit 26 that switches the phase of the clamping motion of the massage unit 24 depending on whether the rotary drive shaft 23 rotates forward or backward.

[0158] In this embodiment, the switching unit 26 is provided on the right massage portion 24R side. That is, the phase of the clamping operation of the right massage portion 24R is different from that of the left massage portion 24L. It is configured to switch according to the phase (constant phase) of the pinching operation.

[0159] As shown in Fig. 10, the driving unit 22 has a driving motor 27 that outputs a rotational driving force, and a gear case 28 that reduces the output rotational driving force to a predetermined speed. The driving motor 27 is a motor that can rotate forward and backward. The rotation direction, speed, etc. of the driving motor 27 are controlled by a control unit. That is, the driving unit 22 reduces the rotational driving force generated by the driving motor 27 by the gear case 28 and transmits it to the rotary drive shaft 23.

[0160] The rotary drive shaft 23 penetrates the base 21 (gear case 28) and is disposed so that its axis faces the left-right direction (horizontal direction). The rotary drive shaft 23 is a long round bar-shaped shaft member and is supported via bearings or the like so that its rotation direction can be freely changed. The rotary drive shaft 23 is disposed perpendicular to the output shaft of the drive motor 27.

[0161] That is, the rotary drive shaft 23 is provided with the drive unit 22 in the middle of the longitudinal direction and the massage units 24L, 24R at both the left and right ends. The rotary drive shaft 23 distributes and transmits the rotational drive force output from the drive motor 27 to the pair of left and right massage units 24L, 24R.

[0162] 10, in this embodiment, the "forward rotation" of the rotation drive shaft 23 is defined as a rotation from rear to top to front, and the "reverse rotation" is defined as a rotation from front to top to rear. The definition of the rotation of the rotation drive shaft 23 may be reversed.

[0163] 10, the massage unit 24 includes a right massage unit 24R for massaging the treatment area on the right side and a left massage unit 24L for massaging the treatment area on the left side. The massage unit 24 also includes a pair of upper and lower arm members 14, 16.

[0164] The right massage portion 24R will be described. Note that the left massage portion 24L has a configuration in which the left and right massage portions 24R and 24L are mirror images of each other, so detailed description thereof will be omitted.

[0165] The right massage portion 24R has a first arm member 14R (massaging arm member 14R) that performs a kneading massage on the upper right side of the shoulder, and a second arm member 16R (grabbing arm member 16R) that performs a gripping massage on the lower right side of the shoulder.

[0166] 10, the first arm member 14R on the right side (massage arm member 14R) has a tip end that protrudes forward and a first right annular fitting portion 33R at its base end. This first right annular fitting portion 33R constitutes a right conversion portion 25R, which will be described later, and fits into the first right rotation boss portion 32R from the outside.

[0167] The rotary drive shaft 23 is disposed in a penetrating state at the base end (first right annular fitting portion 33R) of the first arm member 14R. On the other hand, the tip end of the first arm member 14R is provided with a first treatment member 15R (upper treatment member 15R) that enables a kneading massage to the shoulders.

[0168] Furthermore, a ball joint portion 29 is provided at the base end of the first arm member 14R. The ball joint portion 29 is rotatably connected to the tip 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 arranged in the base 21.

[0169] As a result, when the rotary shaft 31 rotates due to the rotary driving force output from the second drive motor 52, the first arm member 14R swings back and forth via the ball joint portion 39 and the connecting shaft 30, so that a tapping massage can also be performed by the first treatment element 15R. That is, the back massage mechanism 5 of this embodiment is provided with a tapping massage mechanism that can also perform a tapping massage with the first arm member 14R.

[0170] The first massaging element 15R is attached to the tip of the first arm member 14R, which protrudes forward. The first massaging element 15R is a spherical member, and is attached to be rotatable around an axis that faces the protruding direction of the tip and an axis that faces a direction intersecting the protruding direction.

[0171] The first treatment element 15R is provided at a position facing the second treatment element 17R in the vertical direction. The first treatment element 15R swings left and right, and the second treatment element 17R moves toward and away from the first treatment element 15R in the vertical direction. In other words, the first treatment element 15R performs a kneading massage on the upper right shoulder as the first arm member 14R swings due to the rotational driving force of the rotation drive shaft 23.

[0172] 10, a first conversion unit 25 that converts the rotational driving force into swinging motion and transmits it to the first arm member 14 is provided on the base end side of the first arm member 14. The first conversion unit 25 is made up of a first right conversion unit 25R that converts the rotational driving force into 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 swinging motion of the first arm member 14L on the left side.

[0173] The first right conversion portion 25R has a first right rotation boss portion 32R that is attached to the rotating drive shaft 23 and rotates integrally with the rotating drive shaft 23, a first right annular fitting portion 33R that is provided at the base end of the first arm member 14R and externally fits onto the first right rotation boss portion 32R, and a first right regulating portion 34R that regulates the first arm member 14R from rotating together with the rotating drive shaft 23.

[0174] In addition, the first left conversion section 25L has a configuration in which the first right conversion section 25R and the first left conversion section 25L are mirror images of each other, so a description thereof will be omitted.

[0175] The first right rotation boss portion 32R is a member provided on the right end side of the rotation drive shaft 23 and on the base end side of the first arm member 14R. The first right rotation boss portion 32R is a member provided with a small diameter tubular member on the outside and a disk-shaped tubular member on the inside. The outer tubular member is provided eccentrically and inclined with respect to the rotation drive shaft 23. An outer cam surface 35 is formed so as to go around on the outer peripheral surface of the outer tubular member.

[0176] That is, the outer cam surface 35 revolves around the axis of the rotary drive shaft 23 in a state where it is eccentric and inclined with respect to the axial direction of the rotary drive shaft 23. The first right annular fitting portion 33R slidably fits into the outer cam surface 35 from the outside, so that the first arm member 14R is able to swing (rotate) freely with respect to the rotary drive shaft 23. When the rotary drive shaft 23 is rotated, the outer cam surface 35 describes an orbit that is eccentric with respect to the axis of the rotary drive shaft 23 and swings left and right.

[0177] Furthermore, in this embodiment, a small-diameter cylindrical member is provided inside the disk-shaped cylindrical member that constitutes the first right rotation boss portion 32R. An inner cam surface 36 is formed around the outer circumferential surface of the inner cylindrical member.

[0178] That is, the inner cam surface 36 revolves around the axis of the rotary drive shaft 23 in a state eccentric to the axial direction of the rotary drive shaft 23. A slider 42R, which will be described later, slidably fits into the inner cam surface 36 from the outside, allowing the second arm member 14R to move forward and backward in the front-rear direction relative to the rotary drive shaft 23. When the rotary drive shaft 23 is rotated, the inner cam surface 36 describes a revolving orbit that is eccentric to the axis of the rotary drive shaft 23.

[0179] 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 able to fit from the outside into the outer cam surface 35 of the first right rotation boss portion 32R. When the first right annular fitting portion 33R fits externally into the first right rotation boss portion 32R (outer cam surface 35), the first arm member 14R rotates around the axis of the first right rotation boss portion 32R.

[0180] The first right regulating portion 34R in this embodiment is composed of a ball joint portion 27, a connecting shaft 28, and a rotating shaft 29, which constitute a tapping massage mechanism. The tip of the connecting shaft 28 is rotatably connected to the ball joint portion 27, and the base end is restrained by the rotating shaft 29. This configuration forms the first right regulating portion 34R, which regulates the first arm member 14R from rotating together with the rotating drive shaft 23.

[0181] As shown in Fig. 10, a second arm member 16R (grabbing arm member 16R) for applying a gripping massage action to the shoulders is provided inside the first arm member 14R on the right side. The second arm member 16R is provided so as to extend forward (towards the shoulders) from the back massage mechanism 5 side.

[0182] The second arm member 16R is a flat plate-shaped member, and is provided at its base end with a through hole 37 whose axis faces the left-right direction. A restriction pin 44 constituting a second right restriction portion 41R (described later) is inserted through the through hole 37.

[0183] The tip of the second arm member 16R is provided with a second treatment member 17R (upper treatment member 17R) that can grab and massage the shoulders. It is a member formed in a shape.

[0184] The second treatment element 17R is provided at a position facing the first treatment element 15R in the up-down direction. The second treatment element 17R moves toward and away from the first treatment element 15R, which swings left and right, in the up-down and front-rear directions. In other words, the second treatment element 17R grasps and massages the center of the right shoulder as the second arm member 16R moves forward and backward in the up-down and front-rear directions due to the rotational driving force of the rotational driving shaft 23.

[0185] 10, a guide groove portion 38R for guiding a slider 42R (described later) is formed in the middle of the second arm member 16R in the longitudinal direction. The guide groove portion 38R is a hole having a substantially rectangular shape in side view with an opening facing the left-right direction.

[0186] The guide groove 38R allows the second arm member 16R to move up and down and forward and backward. In this embodiment, the guide groove 38R is a rectangular space. A slider 42R that can slide back and forth inside the guide groove 38R is fitted into the guide groove 38R. That is, the rotary drive shaft 23 is disposed in a penetrating state through the base end (guide groove 38R) of the second arm member 16R via the slider 42R.

[0187] Further, a second conversion unit 39 is provided on the base end side of the second arm member 16, which converts the rotational driving force into advancing and retreating motion in the up-down and front-rear directions and transmits it to the second arm member 16. The second conversion unit 39 is made up of a second right conversion unit 39R that converts the rotational driving force into advancing and retreating motion in the up-down and front-rear directions of the right-side second arm member 16R, and a second left conversion unit 39L that converts the rotational driving force into up-down and front-rear directions of the left-side second arm member 16L.

[0188] The second right conversion portion 39R has a first right rotation boss portion 32R (inner cam surface 36) that is attached to the rotation drive shaft 23 and rotates integrally with the rotation drive shaft 23, a second right annular fitting portion 40R that is provided at the base end of the second arm member 16R and fits externally onto the inner cam surface 36 of the first right rotation boss portion 32R, and a second right regulating portion 41R that regulates the second arm member 16R from rotating together with the rotation drive shaft 23.

[0189] In addition, the second left conversion section 39L has a configuration in which the second left conversion section 39L and the second right conversion section 39R are mirror images of each other, so a description thereof will be omitted.

[0190] As shown in Fig. 10, the slider 42R is a pair of thin plate members provided on the left and right sides to sandwich the guide groove portion 38R of the second arm member 16R. The end of the slider 42R that is on the outside of the second arm member 16R is flange-shaped. The slider 42R has a side wall surface 43 that abuts against the long edge (long side) of the guide groove portion 38R.

[0191] A circular through hole 40R with an opening facing the left-right direction is formed in the center of the slider 38R. The through hole 40R serves as a second right annular fitting portion 40R that fits into the inner cam surface 36 provided in the first right rotation boss portion 32R.

[0192] 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, 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. As the side wall surface 43 slides along the long side of the guide groove portion 38R, when the slider 42R moves in the guide groove portion 38R, the second arm member 16R moves forward and backward in the up-down and front-rear directions.

[0193] The second right restriction portion 41R has a restriction pin 44 that restricts the swing direction of the second arm member 16R, a through hole 37 through which the restriction pin 44 passes, and a restriction hole into which the restriction pin 44 is inserted.

[0194] The regulating pin 44 passes through the through hole 37 provided at the base end of the second arm member 16R and is inserted into a regulating hole provided in the gear case 28, thereby connecting the second arm member 16R to the main body side of the back massage mechanism 5 and allowing it to rotate freely around the axis of the regulating pin 44, but restricting it from rotating together with the rotation drive shaft 23.

[0195] Here, the left massage section 24L will be briefly described. The left massage section 24L has a first arm member 14L (massage arm member 14L) that performs a kneading massage on the upper left side of the shoulder, and a second arm member 16L (grab arm member 16L) that performs a gripping massage on the lower left side of the shoulder. A first treatment element 15L is provided at the tip of the first arm member 14L. A second treatment element 17L is provided at the tip of the second arm member 16L.

[0196] As shown in FIG. 10, the back massage mechanism 5 of this embodiment is provided with a switching unit 26 that enables switching between the phase of the clamping operation of the left and right massage units 24, i.e., between two clamping (grabbing and kneading) operations.

[0197] As shown in Figures 11 and 12, the switching unit 26 makes it possible to switch between a "first clamping action" in which the clamping action of the first treatment element 15R and the second treatment element 17R on the right side is performed with a delayed phase relative to the phase of the clamping action of the first treatment element 15L and the second treatment element 17L on the left side, and a "second clamping action" in which the first treatment element 15L and the second treatment element 17L on the left side and the first treatment element 15R and the second treatment element 17R on the right side are performed in the same phase.

[0198] In this embodiment, the switching unit 26 is provided in the right converter 25R, 39R. The switching unit 26 may be provided in the left converter 25L, 39L of the left massage portion 24L.

[0199] As shown in Fig. 10, the switching unit 26 of this embodiment has a switching shaft 45 attached to the rotary drive shaft 23, a hook portion 46 provided on the outer circumferential surface side of the switching shaft 45, and a hook groove portion 47 into which the hook portion 46 is slidably fitted. In this embodiment, the switching unit 26 employs a "half-rotation clutch mechanism" that rotates the switching shaft 45 provided on the rotary drive shaft 23 half a turn in the forward rotation direction or half a turn in the reverse rotation direction, and then delays the movement of the right massage part 24R to switch the phase of the pinching (grabbing and kneading) operation of the right massage part 24R. However, the "half-rotation clutch mechanism 26" includes other than half a turn (180°).

[0200] The switching shaft 45 is a cylindrical member and is attached so as to cover the rotary drive shaft 23. The switching shaft 45 rotates together with the rotary drive shaft 23. The switching shaft 45 rotates a half turn in the forward or reverse direction together with the rotary drive shaft 23, and then rotates the first right rotation boss portion 32R. A protruding hook portion 46 is formed on the outer periphery of the switching shaft 45 on the radially outward side.

[0201] The hook portion 46 of the present embodiment is a plate-shaped member that is provided along the outer periphery of the switching shaft 45 and is long in the axial direction of the switching shaft 45 (the rotation drive shaft 23). That is, the hook portion 46 can be said to be a curved protruding piece that is aligned with a hook groove portion 47 described later.

[0202] 10, the hook portion 46 is a curved member having a side wall of the same arc shape as the outer circumferential curved surface of the switching shaft 45, and two end walls 48, 49. The first end wall 48 is a first engagement surface 48 that engages with a first rotation switching portion 50 of the hook groove portion 47 during forward rotation of the rotary drive shaft 23. The second end wall 49 is a second engagement surface 49 that engages with a second rotation switching portion 51 of the hook groove portion 47 during reverse rotation of the rotary drive shaft 23.

[0203] That is, the hook portion 46 is shaped to fit into the hook groove portion 47, and has a length (height) in the front-rear direction substantially the same as that of the hook groove portion 47. The hook portion 46 slides in the hook groove portion 47 around the axis of the switching shaft 45 (the rotation drive shaft 23).

[0204] In the present embodiment, the hook groove portion 47 is a groove having a crescent-shaped (C-shaped) track around the outer periphery of the switching shaft 45 (rotation drive shaft 23) in a side cross-sectional view. The hook groove portion 52 is provided along the outer periphery of the switching shaft 53, and is a long (deep) groove in the axial direction of the switching shaft 45 (rotation drive shaft 23).

[0205] That is, the hook groove portion 47 is a curved groove that is the same arc as the outer circumferential curved surface of the hook portion 46. Also, the hook groove portion 47 is a curved groove that follows the hook portion 46. That is, the hook groove portion 47 has a shape that the hook portion 46 fits into, and the length (depth) in the front-rear direction is approximately the same as the height of the hook portion 46.

[0206] The hook groove portion 47 is an arc-shaped groove that goes around the outer periphery of the switching shaft 45, and forms a track with two end walls. These two end walls, i.e., side wall portions 50, 51, are rotation switching portions 50, 51 that switch the rotation of the rotary drive shaft 23.

[0207] When the rotary drive shaft 23 rotates forward or backward, the rotation switching units 50, 51 engage the half-rotated hook portion 46, thereby delaying the operation of the right conversion units 25R, 39R and switching the clamping operation of the right massage unit 24R.

[0208] In this embodiment, one end of the semicircular hook groove portion 47 is the first rotation switching portion 50. The first rotation switching portion 50 is a first left conversion portion 25L, a second left conversion portion 25R, and a third left conversion portion 25L. This is a portion for delaying the operation of the first right conversion section 25R and the second right conversion section 39R relative to the operation of the left conversion section 39L.

[0209] That is, during forward rotation of the rotary drive shaft 23, the hook portion 46 of the switching shaft 45 rotates half a rotation in the forward direction around the axis of the rotary drive shaft 23, and then the first engagement surface 48 of the hook portion 46 engages with the first rotation switching portion 50, causing the first right rotation boss portion 32R to start rotating half a rotation behind the rotation of the first left rotation boss portion, thereby delaying the operation of the first right conversion portion 25R and the second right conversion portion 39R relative to the operation of the first left conversion portion 25L and the second left conversion portion 39L, and switching the right massage portion 24R to the "first clamping operation".

[0210] As shown in Figures 11 and 12, when the rotary drive shaft 23 rotates in the "forward direction (rear-up-front)", a "first clamping action" is performed in which the left and right shoulders are alternately grasped and massaged. During this "first clamping action", the left and right first treatment elements 15L, 15R and the second treatment elements 17L, 17R alternately grasp and massage the left and right shoulders (treatment areas) of the user U.

[0211] Specifically, as the rotary drive shaft 23 rotates forward, the switching unit 26 switches to the first clamping operation. While the rotary drive shaft 23 rotates half a turn forward around its axis, the movement of the right massage member 24R is temporarily stopped. After the switching shaft 45 rotates half a turn, the first engagement surface 48 of the hook portion 46 engages with the first rotation switching unit 50 in the hook groove portion 47, and the massage member 24R in the temporarily stopped state starts to move (delay operation). The switching unit 26 switches the right massage portion 24R to a clamping operation phase that is delayed relative to the clamping operation phase of the left massage portion 24L, and causes the right massage portion 24R to perform the first clamping operation (alternate left and right gripping and kneading massage).

[0212] The other end of the semicircular hook groove portion 47 is the second rotation switching portion 51. The second rotation switching portion 51 is a portion for synchronizing the operations of the first right conversion portion 25R and the second right conversion portion 39R and the first left conversion portion 25L and the second left conversion portion 39L when the rotary drive shaft 23 rotates in the reverse direction.

[0213] In other words, when the rotating drive shaft 23 rotates in the reverse direction, the hook portion 46 of the switching shaft 45 rotates half a turn in the reverse direction around the axis of the rotating drive shaft 23, and then the second engagement surface 49 of the hook portion 46 engages with the second rotation switching portion 51, causing the first right rotating boss portion 32R to start rotating together with the first left rotating boss portion, and the operations of the first right conversion portion 25R and the second right conversion portion 39R, and the first left conversion portion 25L and the second left conversion portion 39L are coordinated to switch the right massage portion 24R to the "second clamping operation".

[0214] As shown in Figures 11 and 12, when the rotary drive shaft 23 rotates in the reverse direction (rotating from front to top to back), a second clamping action is performed to simultaneously grip and massage the left and right shoulders. During this second clamping action, the first treatment elements 15L, 15R and the second treatment elements 17L, 17R grip and massage the left and right shoulders (treatment areas) of the user U at the same time.

[0215] Specifically, the rotation drive shaft 23 rotates in the reverse direction, and the switching unit 26 switches to the second clamping operation. While the rotation drive shaft 23 rotates half a turn in the reverse direction around its axis, the movement of the right massage member 24R is temporarily stopped. After the switching shaft 45 rotates half a turn, when the second engagement surface 49 of the hook portion 46 engages with the second rotation switching unit 51 in the hook groove portion 47, the right massage member 24R in the temporarily stopped state starts to move (delayed operation). The switching unit 26 switches the phase of the clamping operation of the right massage portion 24R and the left massage portion 24L to the same phase, and performs the second clamping operation (simultaneous left and right gripping and kneading massage).

[0216] In other words, the switching unit 26 can be considered a delay mechanism that differs the timing of clamping between the first treatment element 15L and the second treatment element 17L (left massage unit 24L) on the left side from the timing of clamping between the first treatment element 15R and the second treatment element 17R (right massage unit 24R) on the right side, and this timing difference allows for alternating left and right gripping and kneading massages.

[0217] As described above, the back massage mechanism 5 of this embodiment can be switched by the switching unit 26 between a "first clamping action" in which the left and right shoulders are grasped and massaged alternately, and a "second clamping action" in which the left and right shoulders are grasped and massaged simultaneously, thereby enabling an effective grasping and kneading massage to be performed and relieving stiffness in the treatment area such as the shoulders.

[0218] Furthermore, in this embodiment, the control unit of the chair type massage machine 1 controls the back massage mechanism 5 to alternately grab and massage the left and right shoulders, and the airbags A to H to massage the left and right shoulders. By controlling the pressing action on the buttocks, thighs, upper arms, back, etc. in coordination with the pressing action on the buttocks, thighs, upper arms, back, etc., as in "Collaborative Massage 1" to "Collaborative Massage 7," it is possible to apply stronger pressure to treatment areas including the shoulders and stretch the shoulders while grabbing them, thereby relieving stiffness in treatment areas such as the shoulders. [Variations] In the chair type massage machine 1 of the present invention described above, the embodiment in which the pressure massage mechanism is composed of one or more airbags has been 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 have been described in detail. Furthermore, modified examples of "cooperative massage 1" to "cooperative massage 4" have also been described in detail. The modified examples are summarized as follows.

[0219] In this modification, the pressure massage mechanism, particularly the pressure massage mechanism arranged on the upper surface of the seat 2, may be a mechanical massage mechanism having a pair of massage members on the left and right that perform a swinging motion, and treatment elements provided at the tips of the massage members. The massage members may perform an eccentric motion or a swinging motion. The massage members may also perform a massage action alternately on the left and right.

[0220] For example, in the massage action of the back massage mechanism 5 of this embodiment, the first massage applicator 15R provided at the tip of the first right arm member 14R and the second massage applicator 17R provided at the tip of the second right arm member 16R may move toward and away from each other in the vertical direction to grasp and massage the right shoulder. In addition, the first massage applicator 15R and the second massage applicator 17R may perform a swinging motion that draws a loop-shaped trajectory.

[0221] Also, the first treatment element 15L provided at the tip of the first arm member 14L on the left side and the second treatment element 17L provided at the tip of the second arm member 16L on the left side may move toward and away from each other in the vertical direction to perform a gripping massage on the left shoulder. In addition, the first treatment element 15L and the second treatment element 17L may perform a swinging motion that draws a loop-shaped trajectory.

[0222] In this way, the back massage mechanism 5 swings the left and right first arm members 14R, 14L and the second arm members 16R, 16L in a loop-like motion up, down, left, and right, alternately or simultaneously moving the first treatment element 15R and second treatment element 17R on the right side, which are lined up vertically, closer to and away from each other, and the first treatment element 15L and second treatment element 17L on the left side, which are lined up vertically, closer to and away from each other.

[0223] In addition, for example, the left and right first massage applicators 15R, 15L and the left and right second massage applicators 17R, 17L may perform a tapping massage.

[0224] The mechanical massage mechanism includes a drive source such as an electric motor and a rotating shaft that is rotated by the drive source. A pair of left and right massage members are eccentrically mounted on the rotating shaft or are mounted via an inclined cam. The mechanical massage mechanism may move in the front-rear direction inside the seat 2.

[0225] When a pair of left and right massage members are provided eccentrically, the massage members (in other words, the arm members) move up and down relative to the upper surface of the seat 2, so that the massage applicators attached to the ends of the massage members push the user's buttocks upward. When pushing up the buttocks, the left and right massage applicators may push up the left and right buttocks alternately. This provides the same action and effect as the airbags A to H pushing up the user's buttocks upward in "Collaborative Massage 1" to "Collaborative Massage 4."

[0226] When a pair of left and right massage members are arranged via an inclined cam, the massage members oscillate and the treatment elements move toward and away from each other, for example, in a loop. Therefore, the treatment elements attached to the ends of the massage members have an upward movement component, which pushes the user's buttocks upward, and thus achieves the same action and effect as the airbags A to H pushing the user's buttocks upward in "Collaborative Massage 1" to "Collaborative Massage 4."

[0227] Furthermore, in the chair-type massage machine 1 of the present invention, if a mechanical massage mechanism is positioned at the position of the airbags G, H, that is, if a so-called double mechanism type is used in which two mechanical massage mechanisms are arranged in the backrest portion 3, the user's back can be pressed forward by gripping the shoulders with the back massage mechanism 5 and moving the massage member of the lower massage mechanism of the double mechanism forward, thereby realizing "cooperative massage 5" and "cooperative massage 6".

[0228] In other words, the chair-type massage machine 1 of the present invention has a control unit that controls the coordinated operation of "the action of alternately grabbing and kneading the left and right shoulders (treatment area) using the back massage mechanism 5" and the action of "pressure massage using the mechanical massage mechanism (first pressing means), side massage mechanism 19 (third pressing means), and back massage mechanism 20 (second pressing means)," allowing for coordinated massage such as applying stronger pressure to the treatment area including the shoulders and stretching the shoulders while grabbing them, thereby allowing for stretching treatments on the body such as relieving stiffness in the treatment areas such as the shoulders without causing any discomfort.

[0229] It should be noted that the embodiments disclosed herein are illustrative in all respects and should not be considered as limiting. In particular, in the embodiments disclosed herein, matters not explicitly stated, such as operating conditions, operation conditions, dimensions and weights of components, do not deviate from the scope of ordinary practice by a person skilled in the art, and are matters that can be easily imagined by a person skilled in the art.

[0230] For example, the control by the control unit which coordinates the action of the back massage mechanism 5 alternately grabbing and kneading the left and right shoulders (treatment area) as described above, and the pressing action against the buttocks, thighs, upper arms, back, etc. by inflating and deflating multiple airbags A to H, i.e., [cooperative massage 1] to [cooperative massage 7], are merely examples and are not limited to those exemplified, and can be modified as appropriate in consideration of the treatment range.

[0231] In addition, the length of the first arm member 14 and the second arm member 16 provided in the back massage mechanism 5, the inclination angle of the kneading arm member 14 relative to the rotation drive shaft 23, and the distance between the first arm member 14 and the second arm member 16 on the left and right can be changed as appropriate taking into account the treatment range.
