[ Structure of massage Unit ]

The structure of the massage unit 8 will be described below.

As shown in fig. 1 to 3 and 5, the backrest 3 is provided with a massage unit 8 for massaging the upper body of the user from the rear (back). The massage unit 8 may be provided in plural numbers (1 in the present embodiment) in the height direction. The massage unit 8 includes a pair of right and left arms 61 and treatment elements 62 provided at both upper and lower ends of the arms 61, and can perform a kneading massage in which the right and left treatment elements 62 approach or separate from each other and a tapping massage in which the right and left treatment elements 62 alternately advance and retreat toward the user side by driving the massage motors M1 and M2. The massage unit 8 is driven by the elevating motor M3 to move upward or downward in the height direction, thereby changing the position relative to the body or performing a rolling massage. The back frame 3a is provided with a pair of right and left guide rails 18 extending in the height direction, and the massage unit 8 moves along the guide rails 18. The massage unit 8 can move in the height direction, and thus can massage the neck to the waist of the user with the treatment members 62.

As shown in fig. 5, the massage unit 8 includes a base frame 60a and a movable frame 60b supported by the base frame 60 a. The base frame 60a has guide wheels 63 fitted to the guide rails 18 on both left and right sides thereof. The height direction can be moved by an elevating mechanism (not shown) including a rack and pinion. The movable frame 60b is supported by the base frame 60a via a swing shaft 64 in the left-right direction. Between the base frame 60a and the movable frame 60b, a forward/backward driving unit 65 formed of an airbag or the like is provided. The movable frame 60b can be advanced and retracted in the front-rear direction about the swing shaft 64 by the driving of the advance and retraction driving unit 65. Further, instead of advancing and retracting the movable frame 60b, only the arm 61 may be advanced and retracted by providing the arm 61 with the advance and retraction driving portion 65.

The arm 61 is connected to a kneading shaft 66 and a tapping shaft 67 extending in the left-right direction. Inclined cams 66a having inclined shaft portions 66b are provided on both right and left sides of the kneading shaft 66, and the arm 61 is attached to the inclined cams 66 a. The left and right inclined shaft portions 66b are inclined with respect to the axial center of the kneading shaft 66 so as to form a substantially splayed shape in front view. Eccentric cams 67a having eccentric shaft portions 67b eccentric with respect to the axial center of the striking shaft 67 are provided on both right and left sides of the striking shaft 67, and the arm 61 is attached to the eccentric cams 67a via a connecting rod 68. The left and right eccentric shaft portions 67b are different in phase from each other, specifically, by 180 degrees, with respect to the axial center of the striking shaft 67. The kneading shaft 66 and the tapping shaft 67 are rotated by driving the massage motors M1 and M2, respectively. The treatment members 62 perform a kneading massage by rotation of the kneading shaft 66, and a tapping massage by rotation of the tapping shaft 67. The arm 61, the kneading shaft 66, and the beating shaft 67, on which the treatment tools 62 are provided, are supported by the movable frame 60 b. Therefore, the treatment members 62 can advance and retreat relative to the user via the movement of the movable frame 60 b.

The arm 61 is swingable in the front-rear direction, and is biased by a biasing member (not shown) such as a spring so that the upper treatment tool 62 protrudes forward. The massage unit 8 also has a sensor 69 that detects body information of the user. The sensor 69 can obtain body information by detecting that the arm 61 has reached a predetermined swing position. Specifically, when the upper treatment tools 62 reach above the shoulders while the massage unit 8 is being raised in the height direction, the load on the treatment tools 62 is released, and the arm 61 swings forward to a predetermined swing position. The sensor 69 detects that the arm 61 has reached a predetermined swing position, and detects the position of the shoulder from the vertical position of the massage unit 8 at that time. The positions of other parts (neck, back, waist, etc.) are calculated based on the positions of the shoulders. The detected body information is stored in the storage unit 50.

[ Structure of side wall part ]

As shown in fig. 1 to 3, side wall portions 7 provided to face the outer surfaces of the shoulders or upper arms of the user are provided on both the left and right sides of the back frame 3a (backrest portion 3). The side wall portion 7 is erected forward at the side of the backrest portion 3. A shoulder massage portion a2 for massaging the outer surface of the shoulder or the upper arm is provided on the inner surface of the side wall portion 7. The shoulder massage portion a2 is constituted by the air bag 20 which is inflated and deflated by the supply and discharge of air. Thus, the shoulder massage parts a2 form a massage part group a2 in pairs.

[ Structure of pillow ]

As shown in fig. 1 to 3, a pillow 5 for supporting the head and/or neck of the user is provided on the upper front surface of the backrest 3. A pair of right and left head massage portions a1 are provided on the front surface of the pillow 5 so as to face the back of the head and/or neck. The head massage portion a1 is constituted by the air bag 20 which is inflated and deflated by the supply and discharge of air. Thus, the head massage portions a1 form a massage portion group a1 by making a pair on the left and right. The head massage portion a1 may be provided to face the outer side surface of the head and/or the neck. In this case, the inner surface of a wall portion (not shown) that is erected forward may be provided. Also, the head massaging portion a1 may be provided directly on the upper front surface of the backrest portion 3 instead of the pillow portion 5.

[ Structure of leg rest ]

As shown in fig. 1 to 3, the leg rest 4 includes a pair of left and right leg support portions 40 that support the lower legs of the user and a pair of left and right foot support portions 41 that support the feet of the user. The leg support 40 includes a bottom wall 40a provided to face the back of the lower leg of the user, side walls 40b provided to stand forward from both left and right ends of the bottom wall 40a, and a center wall 40c provided to stand forward from the left and right center of the bottom wall 40 a.

The controller 10 includes a screen 10a that can be visually recognized by a user, a touch panel 10b that the user operates on the screen 10a with a fingertip, and a speaker 33 that outputs a display content of the screen 10a by voice. The speaker 33 is described as having the controller 10, but is not limited to this, and may be provided in the upper part of the backrest 3 (around the ears of the user sitting thereon) and the pillow 5. Further, the posture of the backrest 3 can be changed by reclining the chair and the posture of the leg rest 4 can be changed by swinging the chair up and down by operating the controller 10. Further, the massage unit 8, the arm massage unit 70, and the massage units a1 to a8 that need to be operated may be selected, or the operation (technique, strength, etc.) of the massage unit 8, the arm massage unit 70, and the massage units a1 to a8 may be changed. Instead of the operation through the touch panel 10b, the operation may be performed only through the use of the physical keys 31 disposed in the controller 10 and the voice recognition unit 32 of the microphone (not shown) provided in the controller 10. By such a design, the user can easily select. A microphone (not shown) as the voice recognition unit 32 may be provided on the upper portion of the backrest 3 or the pillow 5, instead of the controller 10. By not providing the microphone in the controller 10 in this way, the user can select a state of leaning on the backrest 3 by the voice recognition unit 32 without having to change his or her posture.

Fig. 6 is a perspective view of the left arm support portion 6, in which (a) is a view showing the arm support portion 6 and the arm massage unit 70, and (b) is a view showing the arm massage unit 70 and the moving member 73 in which the arm support portion 6 is omitted. Fig. 7 is a rear right perspective view of the left arm support portion 6. Fig. 8 is a view showing the arm massage unit 70 and the moving member 73, which is a plan view of fig. 6 (b). Fig. 9 is a view showing the arm massage unit 70 and the moving member 73, which is a front view of fig. 6 (b).

The structure of the left arm support portion 6 will be described below with reference to fig. 1 to 3 and 6 to 9. Since the right arm support portion 6 and the left arm support portion 6 have the same configuration, the left arm support portion 6 will be described.

As shown in fig. 1 to 3 and 6 to 9, arm support portions 6 having support surfaces 6a for supporting the arms (hands and forearms) of the user are provided on both the left and right sides of the seat portion 2. The arm support portion 6 is provided with a pair of massage portions 15 that sandwich the support surface 6a and massage the user's arms (hands and forearms) in the left-right direction. The pair of massage parts 15 includes a1 st massage part 71a located inside the user's arm and a2 nd massage part 71b located outside the user's arm. The arm support portion 6 has an opening 6b on the support surface 6a, which is long in the longitudinal direction of the arm of the user. The 1 st massage part 71a is positioned at the opening 6b of the support surface 6a, and the 2 nd massage part 71b is positioned outside the support surface 6 a. With such a design, the interval between the 1 st massage part 71a and the 2 nd massage part 71b can be set without being limited by the width of the supporting surface 6 a. In the above description, the example in which the number of the openings 6b is 1 was described, but the present invention may be configured such that 2 openings 6b are provided and the 1 st massage part 71a and the 2 nd massage part 71b are provided in the respective openings 6 b.

A driving unit 72 for driving the pair of massage units 15 is provided below the support surface 6a of the arm support unit 6. With such a design, the driving unit 72 can be positioned at a position not interfering with the massage by the pair of massage units 15. The drive unit 72 includes: a massage motor M4 (not shown); an eccentric cam 72b connected to the drive shaft 72a and the drive shaft 72a for transmitting the drive of the massage motor M4 and rotating integrally; and a housing 72c for accommodating the massage motor M4 and the like. The drive shaft 72a is provided such that the axis of rotation thereof is in the left-right direction (refer to fig. 9). The eccentric cam 72b is coupled to left and right ends of the drive shaft 72a in the left-right direction so as to sandwich the arm of the user from the left-right direction. Each eccentric cam 72b is attached to the 1 st massage part 71a and the 2 nd massage part 71b of the pair of massage parts 15. With such a configuration, the driving unit 72 can drive the 1 st massage unit 71a and the 2 nd massage unit 71b via the driving shaft 72a, and thus, a mechanical massage can be performed with the arms of the user being sandwiched from the left and right.

In order to prevent the rotation accompanying the rotation of the eccentric cam 72b (drive shaft 72a), the 1 st massage part 71a and the 2 nd massage part 71b have a link mechanism 73 that restricts the range of operation with respect to the rotational direction of the eccentric cam 72b to a predetermined range and allows the movement of the drive shaft 72a in the axial direction. The link mechanism 73 has: a link 73a having a spherical end; a joint 73b coupled to the link 73a to be rotatable in the left-right direction; and a joint shaft 73c that is coupled to the joint portion 73b so as to be rotatable in the vertical direction and that is coupled to the first joint 73b of each of the 1 st massage unit 71a and the 2 nd massage unit 71 b. The link 73a is connected to the 1 st massage part 71a, the 2 nd massage part 71b, and the spherical hole by a ball joint method.

By the operation restriction by the eccentric cam 72b and the connecting member 73, the pair of massage parts 15 do not rotate along with the rotation of the eccentric cam 72b, and perform the swinging motion in the direction intersecting the axial direction of the rotation shaft of the drive shaft 72a and the direction along the axial direction. The pair of massage units 15 can perform a massage operation of kneading the arms of the user by swinging in the direction along the axis of rotation of the drive shaft 72a, and the pair of massage units 15 can perform a massage operation of twisting the arms of the user by swinging in the direction intersecting the axis of rotation of the drive shaft 72 a. As a specific content of the kneading operation by the pair of massage units 15, the eccentric cam 72b disposed on the left and right sides is disposed with its phase changed by 180 degrees. With this configuration, the width interval between the pair of massage units 15, i.e., the 1 st massage unit 71a and the 2 nd massage unit 71b, is set to a narrow or wide state while the drive shaft 72a rotates 1 time, so that the user can grip or release the arm from the left and right. This operation is repeated, whereby the kneading operation can be performed. By providing a sensor (not shown) for detecting the rotational position of the drive shaft 72a, it is possible to detect a narrow state or a wide state of the width interval between the 1 st massage part 71a and the 2 nd massage part 71 b. With such a design, the width interval between the 1 st massage part 71a and the 2 nd massage part 71b can be kept in a narrow state or a wide state.

The pair of massage units 15, i.e., the 1 st massage unit 71a and the 2 nd massage unit 71b, are provided with arm massage units a3, respectively. The arm massage portion a3 is constituted by the air bag 20 that expands and contracts by the supply and discharge of air. Thus, the arm massage parts A3 form a massage part group A3 by making a pair on the left and right. Through such design, not only can carry out mechanical type massage, can also carry out pneumatic massage through the gasbag.
