DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] 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.

[0019] 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, some of the components are omitted in the drawings for ease of viewing. The directions of the chair-type massage machine 1, such as up / down, front / back, left / right, etc., are as shown in FIG. 1. The directions of the back massage mechanism 5, such as up / down, left / right, etc., are as shown in FIG. 1 and FIG. 2. The directions of the seat massage mechanism 4, such as up / down, front / back, left / right, etc., are as shown in FIG. 1 and FIG. 3. 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.

[0020] Fig. 1 is a schematic diagram showing an outline of a chair type massage machine 1 of the present invention. Fig. 2 is a schematic diagram showing a configuration of a back massage mechanism 5 of this embodiment. Fig. 3 is a schematic diagram showing a configuration of a seat massage mechanism 4 of this embodiment.

[0021] As shown in FIG. 1, the chair-type massage machine 1 of this embodiment has a seat 2 that is spacious enough for a user to sit on, and a backrest 3 provided behind the seat 2 and against which the user can lean.

[0022] The seat 2 has legs 6 made up of a combination of square bar-shaped members, and is supported from below at a predetermined height by the legs 6. The entire seat 2 is covered with a casing, a sheet, or the like. A cushion member is provided on the upper surface of the seat 2. Although not shown, armrests are provided on both the left and right sides of the seat 2.

[0023] In the present embodiment, a seat massage mechanism 4 is provided inside the seat 2, which performs massage actions such as kneading, tapping, and grabbing on the user's lower limbs (second treatment area) from the buttocks to the thighs (backs of the thighs).

[0024] As shown in FIG. 3, the seat massage mechanism 4 of this embodiment includes a second rotating shaft 26 that transmits a rotational driving force from a driving motor 30, and a cylindrical second rotating shaft 26 attached to the second rotating shaft 26. It has a boss portion 37, an endless and inclined cam surface 38 formed on the periphery of the second rotating boss portion 37, and a second annular fitting portion 39 provided at the base end of the seat arm member 27 and fitted freely slidably onto the inclined cam surface 38.

[0025] The second rotating bosses 37 are provided in a pair on the left and right at a predetermined interval along the second rotating shaft 26. The inclined cam surfaces 38R, 38L of the pair of second rotating bosses 37R, 37L arranged on the left and right are inclined in the same direction. In other words, if the right seat arm member 27R inclines to the right, the left seat arm member 27L also inclines to the right. Similarly, if the right seat arm member 27R inclines to the left, the left seat arm member 27L also inclines to the left. The device configuration of the seat massage mechanism 4 will be described in detail later.

[0026] The backrest 3 is a member provided at the rear of the seat 2, and is formed in a flat plate shape with a sufficient thickness so that the user can lean against it. The backrest 3 has a support frame 7 made up of a combination of square rod-shaped members. The support frame 7 is supported at the rear of the seat 2 so as to be able to swing freely in the front-rear direction.

[0027] The entire backrest 3 is covered with a casing, a sheet, etc. A cushion member is provided on the front surface of the backrest 3. The backrest 3 can be reclined relative to the seat 2 by a position changing mechanism (not shown) disposed within the seat 2.

[0028] In this embodiment, a back massage mechanism 5 is provided inside the backrest 3, which performs massage actions such as kneading, tapping, and grabbing on the back (first treatment area) of the user leaning against the backrest 3, from the shoulders through the back to the lumbar region.

[0029] The front side of the backrest portion 3 is open toward the front, and a back arm member 10 constituting the back massage mechanism 5 is provided so as to protrude forward from the open front side.

[0030] As shown in FIG. 2, the back massage mechanism 5 of this embodiment has a first rotating shaft 9 that transmits the rotational driving force from the drive motor 13, a disk-shaped first rotating boss portion 18 attached to the first rotating shaft 9, an endless and inclined cam surface 19 formed on the periphery of the first rotating boss portion 18, and a first annular fitting portion 20 provided at the base end of the back arm member 10 and fitted onto the inclined cam surface 19 so as to be freely slidable.

[0031] The first rotating bosses 18 are provided in a pair on the left and right sides at a predetermined interval along the first rotating shaft 9. The inclined cam surfaces 19R, 19L of the left and right first rotating bosses 18R, 18L are inclined in the opposite directions relative to each other. In other words, if the right back arm member 10R inclines to the right, the left back arm member 27L inclines to the left. The device configuration of the back massage mechanism 5 will be described in detail later.

[0032] The chair type massage machine 1 of this embodiment has a function of simultaneously and appropriately coordinating the seat massage mechanism 4 and the back massage mechanism 5 when providing a massage action to the user. In this embodiment, the seat massage mechanism 4 and the back massage mechanism 5 work together to provide a more effective massage to the user.

[0033] 4A and 4B are diagrams showing a series of operations in the back massage mechanism 5 and the seat massage mechanism 4, and are schematic diagrams showing an example of the swinging motion of the back arm member 10 approaching and moving away from each other and the swinging motion of the seat arm member 27 in the same direction on the left and right.

[0034] As shown in Figures 4A and 4B, the back massage mechanism 5 of this embodiment is configured to perform a "first rocking motion" in which the first treatment members 17R, 17L provided at the ends of a pair of left and right back arm members 10R, 10L move toward and away from each other in the left-right direction, tracing a loop-shaped trajectory.

[0035] In addition, the seat massage mechanism 4 is configured to perform a "second rocking motion" in which the second treatment applicators 35, 36 (in this embodiment, the left and right second front treatment applicators 35R, 35L and the left and right second rear treatment applicators 36R, 36L) provided at the ends of the pair of left and right seat arm members 27R, 27L tilt so as to rock (swing) in the same direction on the left and right.

[0036] In other words, the inclined cam surfaces 38 formed on the left and right second rotating boss portions 37R, 37L are inclined in the same direction, and the left and right second rotating boss portions 37R, 37L rotate to perform the second operation. A second rocking motion occurs in which the massagers 35 and 36 tilt so as to rock left and right in the same direction.

[0037] That is, the chair-type massage machine 1 of this embodiment has a function of linking the "first rocking motion" of the back massage mechanism 5 and the "second rocking motion" of the seat massage mechanism 4.

[0038] In detail, by performing a "first rocking motion" on the pair of left and right back arm members 10R, 10L to move the left and right first treatment members 17R, 17L towards and away from each other, a kneading massage is given to the back, and by performing a "second rocking motion" on the pair of left and right seat arm members 27R, 27L to rock the left and right second front treatment members 35R, 35L and second posterior treatment members 36R, 36L in the same direction on the left and right, a kneading massage is given to the thighs (backs of the thighs) to the waist, etc.

[0039] More specifically, in the back massage mechanism 5, a first swinging motion is performed on the pair of left and right back arm members 10R, 10L, causing the left and right first treatment members 17R, 17L to move closer to and away from each other so that the user's back area from shoulders to back to waist is massaged as if by a first massage therapist, and at the same time, in the seat massage mechanism 4, a second swinging motion is performed on the pair of left and right seat arm members 27R, 27L, causing the left and right second front treatment members 35R, 35L and the left and right second posterior treatment members 36R, 36L to swing in the same direction left and right so that the user's back area from shoulders to back to waist is massaged as if by a second massage therapist, for example.

[0040] First, when a user sits on the seat 2 and leans against the backrest 3, for example, the right shoulder comes into contact with the first right treatment element 17R of the right back arm member 10R, and the left shoulder comes into contact with the first left treatment element 17L of the left back arm member 10L.

[0041] In addition, the right thighs and buttocks abut against the second right front treatment element 35R and the second left rear treatment element 36R of the right seat arm member 27R, and the left thighs and buttocks abut against the second left front treatment element 35L and the second left rear treatment element 36L of the left seat arm member 27L.

[0042] The user operates an operation panel provided on the chair-type massage machine 1 to perform the interlocking operation of the first rocking motion and the second rocking motion. The back massage mechanism 5 is driven to perform the first rocking motion in which the pair of left and right back arm members 10R, 10L move toward and away from each other. At the same time, the seat massage mechanism 4 is driven to perform the second rocking motion in which the pair of left and right seat arm members 27R, 27L move in the same left and right direction.

[0043] In the back massage mechanism 5, the drive motor 13 of the first drive unit 8 is driven. The drive motor 13 outputs a rotational drive force, which is input to a gear case 14. The first rotating shaft 9 is rotated by the rotational drive force.

[0044] The first right conversion section 11R converts the rotational driving force of the first rotating shaft 9 into "front-back and left-right movement" and transmits it to the right back arm member 10R. The right back arm member 10R swings three-dimensionally up and down, front-back and left-right.

[0045] The first left conversion section 11L converts the rotational driving force of the first rotating shaft 9 into "front-back and left-right movement" and transmits it to the left back arm member 10L. The left back arm member 10L swings three-dimensionally up and down, front-back and left-right.

[0046] As shown in Figures 4A and 4B, when the left and right back arm members 10R, 10L are swinging three-dimensionally up and down, front and back, and left and right, for example, the front end of the right back arm member 10R swings inward to the left and the front end of the left back arm member 10L swings inward to the right, causing the first right treatment member 17R and the first left treatment member 17L to come closer to each other.

[0047] Thereafter, the front end of the right back arm member 10R swings outward to the right, and the front end of the left back arm member 10L swings outward to the left, causing the first right treatment element 17R and the first left treatment element 17L to move away from each other.

[0048] In this way, the back massage mechanism 5 causes the left and right back arm members 10R, 10L to swing in a loop-like motion (front-back and left-right motion) in the left-right direction, and alternates between moving the first treatment members 17R, 17L arranged side by side toward and away from each other. The right shoulder of the user is massaged by the first right treatment member 17R moving toward and away from each other, and the left shoulder of the user is massaged by the first left treatment member 17L moving toward and away from each other.

[0049] On the other hand, in the seat massage mechanism 4, the drive motor 13 of the second drive unit 25 is driven. The drive motor 30 outputs a rotational driving force, and the rotational driving force is input to the gear case 27. The second rotating shaft 26 rotates by the rotational driving force.

[0050] In the second right conversion section 28R, the rotational driving force of the second rotating shaft 26 is converted into "up / down / left / right movement" and transmitted to the right seat arm member 27R. The right seat arm member 27R swings three-dimensionally up / down, front / back, and left / right.

[0051] The second left conversion section 28L converts the rotational driving force of the second rotating shaft 26 into "up / down / left / right movement" and transmits it to the left seat arm member 27L. The left seat arm member 27L swings three-dimensionally up / down, front / back, and left / right.

[0052] As shown in Fig. 4A, the right arm member 27R swings the second right front treatment member 35R at the front end inward to the left, and the left arm member 27L swings the second left front treatment member 36L at the front end inward to the left. That is, the second right front treatment member 35R and the second left front treatment member 36L swing in the same left direction.

[0053] At this time, the second right rear treatment element 36R at the rear end of the right seat arm member 27R swings outward to the right. The second left rear treatment element 36L at the rear end of the left seat arm member 27L swings inward to the right. That is, the second right rear treatment element 36R and the second left rear treatment element 36L swing in the same right direction.

[0054] As shown in Fig. 4B, the right arm member 27R then swings the second right front treatment element 35R at the front end outward to the right, and the left arm member 27L also swings the second left front treatment element 35L at the front end inward to the right. That is, the second right front treatment element 35R and the second left front treatment element 36L swing in the same right direction.

[0055] At this time, the second right rear treatment element 36R at the rear end of the right seat arm member 27R swings inward to the left. The second left rear treatment element 36L at the rear end of the left seat arm member 27L swings outward to the left. That is, the second right rear treatment element 36R and the second left rear treatment element 36L swing in the same left direction.

[0056] In this way, in the seat massage mechanism 4, in accordance with the approaching and moving away swinging motion (first swinging motion) of the left and right back arm members 10R, 10L of the back massage mechanism 5, the second right front treatment device 35R and the second right rear treatment device 36R provided on the right seat arm member 27R and the second left front treatment device 35L and the second left rear treatment device 36L provided on the left seat arm member 27L swing in the same direction on the left and right (second swinging motion) to cooperate in performing a kneading massage.

[0057] In other words, in the seat massage mechanism 4, a second rocking motion is performed on the pair of left and right seat arm members 27R, 27L to rock in the same direction on the left and right, and a kneading massage is performed by alternating between the left and right second front treatment members 35R, 35L pushing in first and then the left and right second posterior treatment members 36R, 36L pushing in against the second treatment areas such as the buttocks and thighs (back of the thighs), and a first rocking motion is performed on the pair of left and right back arm members 10R, 10L to move towards and away from each other, and a kneading massage is performed by the first treatment members 17R, 17L on the first treatment area, which is the back area from the shoulders to the back to the waist, by linking these motions together, an effective kneading massage can be given to the back, thighs, buttocks, etc. simultaneously.

[0058] In this embodiment, the swing distance of the first treatment element 17 of the back massage mechanism 5 and the swing distance of the second treatment elements 35, 36 of the seat massage mechanism 4 may be changed to be the same or different.

[0059] In addition, the distance between the pair of left and right first treatment members 17 of the back massage mechanism 5 when they are closest to each other and the distance between the pair of left and right second treatment members 35, 36 of the seat massage mechanism 4 may be changed so as to be the same or different.

[0060] The distance between the pair of left and right first treatment members 17 of the back massage mechanism 5 when they are farthest apart and the distance between the pair of left and right second treatment members 35, 36 of the seat massage mechanism 4 may be changed so as to be the same or different.

[0061] That is, the amplitude of the first treatment element 17 and the amplitude of the second treatment elements 35, 36 may be the same, or one of them may be larger or smaller.

[0062] In addition, the rocking speed of the first massage element 17 of the back massage mechanism 5 and the rocking speed of the second massage elements 35, 36 of the seat massage mechanism 4 are changed to be the same speed or different speeds. For example, the swing speed of the back arm member 10 may be changed to a speed faster than normal, and the swing speed of the seat arm member 27 may be changed to a speed slower than normal.

[0063] The seat massage mechanism 4 of this embodiment is movable in the front-rear direction inside the seat 2 along the seat guide rail 44. The back massage mechanism 5 is movable in the up-down direction inside the backrest 3 along the back guide rail 23.

[0064] It is also possible to change the moving speed of the seat massage mechanism 4 and the moving speed of the back massage mechanism 5. The left and right distances between the pair of back arm members 10R, 10L and the pair of seat arm members 27R, 27L may be changeable.

[0065] In addition, the distance between the left and right first treatment members 17R, 17L, the rocking speed of the first treatment member 17 and the second treatment member 35, 36, and the left and right spacing between the left and right back arm members 10R, 10L and the seat arm members 27R, 27L can be changed as appropriate.

[0066] The back massage mechanism 5 and the seat massage mechanism 4 may be configured to be switchable between a "first rocking motion" and a "second rocking motion." In other words, the back massage mechanism 5 may be made to perform a "second rocking motion," and the seat massage mechanism 4 may be made to perform a "first rocking motion."

[0067] For example, the second treatment applicators 35, 36 of the pair of left and right seat arm members 27 may be made to perform a first swinging motion in which they move towards and away from each other in the left-right direction, and the first treatment applicators 17 of the pair of left and right back arm members 10 may be made to perform a second swinging motion in which they tilt so as to swing in the same left and right direction.

[0068] As described above, according to the chair-type massage machine 1 of the present invention, the seat massage mechanism 4 and the back massage mechanism 5 are linked to enable different massage operations to be performed simultaneously on separate treatment areas, such as the first treatment area from the shoulders to the back to the lumbar region and the second treatment area from the thighs (back of the thighs) to the buttocks, thereby further improving the massage sensation and providing a greater relaxation effect.

[0069] That is, in this embodiment, the desired massage action can be achieved by coordinating the approaching and separating movement (first rocking motion) of the back arm member 10 in the back massage mechanism 5 with the left and right rocking motion (second rocking motion) of the seat arm member 27 in the seat massage mechanism 4, giving the user the sensation of receiving a massage in which each treatment area is being stretched and relaxed at the same time.

[0070] Furthermore, by appropriately adjusting the forward and backward movements of the two massage mechanisms 4, 5, the left-right spacing between the arm members 10, 27, and the drive speed, an effective massage can be received.

[0071] The user can obtain a further relaxing effect on each of two or more different treatment areas, for example, the back area from the shoulders to the back to the waist when leaning against the backrest portion 3, and the lower limbs such as the buttocks and thighs (back of the thighs) when seated on the seat portion 2.

[0072] Next, the configurations of the back massage mechanism 5 and the seat massage mechanism 4 of this embodiment will be described in detail.

[0073] 1 and 2, the back massage mechanism 5 of this embodiment is capable of kneading massage and tapping massage. The back massage mechanism 5 has a first drive unit 8 that generates a rotational driving force, a first rotating shaft 9 that rotates by the rotational driving force, a back arm member 10 that performs a kneading massage on the back (first treatment portion) from the shoulders to the back to the lumbar region, and a first conversion unit 11 that is disposed on the first rotating shaft 9 and converts the rotational driving force into a rocking motion in the front-back and left-right directions and transmits it to the back arm member 10.

[0074] The first drive unit 8 is disposed on a base body 12, and rotates the rotary drive shaft 9. The first drive unit 8 has a drive motor 13 that outputs a rotary drive force, and a gear case 14 that adjusts the output rotary drive force to a predetermined speed.

[0075] The rotation direction, speed, etc. of the drive motor 13 can be controlled. The drive motor 13 is disposed above a gear case 14 provided on the base body 12. The drive motor 13 is a motor that can rotate in both forward and reverse directions.

[0076] In this embodiment, the drive motor 13 is provided with an output shaft that outputs a rotational drive force facing downward. A worm gear is attached to the output shaft of the drive motor 13. The worm gear meshes with a worm wheel attached to a transmission shaft. Although not shown, the transmission shaft is disposed behind the output shaft of the drive motor 13 and inside the gear case 14 with its axis oriented in the left-right direction.

[0077] That is, the first drive unit 8 transmits the rotational drive force generated by the drive motor 13 to the first rotating shaft 9 after adjusting the speed by the gear case 14.

[0078] The first rotating shaft 9 is disposed so that its axis is horizontal and faces the left-right direction, penetrating a gear case 14 provided on the base body 12. The first rotating shaft 9 (kneading rotating shaft) also penetrates the base end side of the back arm member 10. The first rotating shaft 9 is a long, round bar-shaped shaft member, and is supported by a support member 15 via a bearing so that the rotation direction can be freely changed.

[0079] The first rotating shaft 9 is disposed in front of the drive motor 13. The first rotating shaft 9 is disposed so as to be perpendicular to the axis of the output shaft of the drive motor 13. A worm wheel 16 is attached to the left side of the first rotating shaft 9 in the longitudinal direction. The worm wheel 16 is disposed in a gear case 14 and meshes with a worm gear attached to a transmission shaft. In other words, the rotational driving force is transmitted in the order of the output shaft of the drive motor 13 -> the transmission shaft -> the first rotating shaft 9.

[0080] 2, 4A, 4B, etc., the back arm member 10 performs a rocking motion to give a kneading massage to the back (first treatment area) of the user from the shoulders to the back to the lumbar region. The back arm members 10 are provided in pair on the left and right with a predetermined distance between them.

[0081] The back arm member 10 (massage arm member) is formed in an arm shape and is disposed so that its tip (front end) protrudes forward. A first treatment element 17 is attached to the tip (front end) of the back arm member 10 to apply a massage action to the back part of the user from the shoulders to the back to the waist.

[0082] An annular fitting portion 20 constituting the first conversion portion 11 is provided at the base end (rear end) of the back arm member 10. In other words, the first rotation shaft 9 penetrates the base end of the back arm member 10 in the left-right direction.

[0083] A right back arm member 10R is provided on the right side of the first rotating shaft 9. A first right treatment element 17R is attached to the tip (front end) of this right back arm member 10R, which performs a kneading massage on the user's right back region from the shoulder to the back to the waist.

[0084] A left back arm member 10L is provided on the left side of the first rotating shaft 9. A first left treatment element 17L is attached to the tip (front end) of this left back arm member 10L, which performs a kneading massage on the left side of the user's back, from the shoulder to the back to the waist.

[0085] In other words, the distance between the left and right first massage members 17R, 17L is such that the first right massage member 17R can abut against the user's back from the shoulder to the back to the waist on the right side, and the first left massage member 17L can abut against the user's back from the shoulder to the back to the waist on the left side.

[0086] The left and right pair of back arm members 10R, 10L swing back and forth and side to side (a swinging motion that loops left and right) enables the left and right first treatment members 17R, 17L to provide an effective kneading massage from behind to the user's back, from the shoulders to the back to the waist.

[0087] The left and right back arm members 10R, 10L are three-dimensionally oscillated up and down, front and rear, and left and right by the first conversion parts 11R, 11L, which are referred to as "front and rear, left and right movement" in this embodiment. The distance between the pair of left and right back arm members 10R, 10L (first treatment members 17R, 17L) may be variable so that it can be adjusted to the shoulder width of the user.

[0088] The first conversion unit 11 is provided on the base end side of the back arm member 10, and converts the rotational driving force of the first rotating shaft 9 into a rocking motion in the front, rear, left and right directions, and transmits it as a kneading massage action. The first conversion unit 11 has a first rotating boss portion 18 that rotates integrally with the first rotating shaft 9, a first annular fitting portion 20 that is provided on the base end side of the back arm member 10 and fits onto the first rotating boss portion 18, and a first restricting portion 21 that restricts the back arm member 10 from rotating together with the first rotating shaft 9. A first right conversion unit 11R is provided on the base end side of the right back arm member 10R. Also, a first left conversion unit 11L is provided on the base end side of the left back arm member 10L.

[0089] The first rotation boss portion 18 of this embodiment has the first rotation shaft 9 penetrating through its inside, and has a cam surface 19 on its outer circumferential surface that is inclined relative to the first rotation shaft 9. The first rotation boss portion 18 (inclined boss portion) is It rotates while being inclined with respect to the axis of the first rotating shaft 9. Incidentally, the inclined cam surface 19 may be, for example, inclined and eccentric with respect to the first rotating shaft 9.

[0090] The first right rotation boss portion 18R is provided on the right side of the first rotation shaft 9. The first left rotation boss portion 18L is provided on the left side of the first rotation shaft 9. The inclinations of the left and right first rotation boss portions 18R, 18L (inclined cam surfaces 19) are inclined in relative opposite directions between the pair of left and right back arm members 10R, 10L, for example.

[0091] The first annular fitting portion 20 is formed on the base end side of the back arm member 10, and externally fits the first rotation boss portion 18 in a relatively rotatable state. That is, the inner diameter of the first annular fitting portion 20 is approximately the same as the outer diameter of the inclined cam surface 19 of the first rotation boss portion 18.

[0092] The first right annular fitting portion 20R fits around the first right rotation boss portion 18R in a relatively rotatable state. The first left annular fitting portion 20L fits around the first left rotation boss portion 18L in a relatively rotatable state. The left and right first annular fitting portions 20R, 20L are arranged so that the pair of left and right back arm members 10R, 10L are inclined in relatively opposite directions to each other due to the inclination of the left and right first rotation boss portions 18R, 18L.

[0093] The first restricting portion 21 is provided on the first annular fitting portion 20 and restricts the first annular fitting portion 20 from co-rotating with the first rotation boss portion 18. The first restricting portion 21 has a restricting pin provided on the first annular fitting portion 20 and a restricting groove into which the restricting pin is slidably fitted. The first right annular fitting portion 20R is provided with a first right restricting portion 21R. In addition, the first left annular fitting portion 20L is provided on the base end side thereof with a first left restricting portion 21L.

[0094] The regulating portion 21 in this embodiment is a ball joint portion that regulates the back arm member 10 from rotating together with the first rotation shaft 9 by fitting a spherical regulating pin freely sliding into a spherical concave regulating groove.

[0095] As a result, the back arm member 10 swings due to the inclined rotation of the first rotating boss portion 18 into which the first annular fitting portion 20 fits and the restriction of the co-rotation by the first restricting portion 21. Also, because it is a ball joint portion, the back arm member 10 is constrained during a hitting massage, but has a certain degree of freedom and is also able to swing.

[0096] The back massage mechanism 5 may be provided with a switching unit that switches the phase of the front-rear and left-right rocking motion of the pair of left and right back arm members 10R, 10L when the first rotating shaft 9 rotates forward and backward.

[0097] As shown in FIG. 2, the back massage mechanism 5 of this embodiment is equipped with a hitting drive unit 22 that hits the first treatment element 17 against the user's back from the shoulders to the back to the lumbar region at short time intervals, thereby performing a hitting massage on the back by the striking of the first treatment element 17.

[0098] The back massage mechanism 5 of this embodiment moves in the vertical direction (inclined direction) along a pair of left and right back guide rails 23 arranged inside the backrest portion 3 (support frame 7). The back guide rails 23 are rail members that are long in the vertical direction. The back guide rails 23 of this embodiment are curved and bulge forward from the lower end to the vertical midpoint.

[0099] The back guide rail 23 has a rack gear 23a and a rail groove 23b, and is provided on the support frame 7 in pair on the left and right.

Although not shown, the transmission shaft is arranged below the output shaft 30a of the drive motor 30 and inside the gear case 31 with its axis facing in the left-right direction.

[0104] That is, the second drive unit 25 transmits the rotational drive force generated by the drive motor 30 to the second rotating shaft 26 after adjusting the speed by the gear case 31.

[0105] The second rotating shaft 26 is disposed penetrating a gear case 31 provided on a base 29 so that its axis is horizontal and faces the left-right direction. The second rotating shaft 26 (seat rotating shaft) also penetrates the base end side of the seat arm member 27. The second rotating shaft 26 is a long, round bar-shaped shaft member, and is supported by a support member 33 via a bearing 32 so that the rotation direction can be freely changed.

[0106] The second rotating shaft 26 is disposed above the drive motor 30. The second rotating shaft 26 is disposed so as to be perpendicular to the axis of the output shaft 30a of the drive motor 30. A worm wheel 34 is attached to the right side in the longitudinal direction of the second rotating shaft 26. The worm wheel 34 is disposed in a gear case 31 and meshes with a worm gear attached to the transmission shaft. In other words, the rotational driving force is transmitted in the order of the output shaft 30a of the drive motor 30 - the transmission shaft - the second rotating shaft 26.

[0107] As shown in Fig. 3 to Fig. 4B, the seat arm members 27 perform a rocking motion to massage the thighs (backs of the thighs), buttocks, etc. of the user, pressing from below to above. A pair of the seat arm members 27 are provided on the left and right sides with a predetermined distance between them. The seat arm members 27 are formed in an arm shape and are provided along the front-rear direction.

Meanwhile, a second right rear massager 36R for kneading and massaging the user's right thigh (back of the thigh), buttocks, etc. is attached to the rear end of the right seat arm member 27R.

[0111] Further, a left seat arm member 27L is provided on the left side of the second rotating shaft 26. A second left front treatment element 35L for kneading and massaging the left thigh (back of the thigh) and buttocks of the user is attached to the front end of the left seat arm member 27L. Meanwhile, a second left rear treatment element 36L for kneading and massaging the left thigh (back of the thigh) and buttocks of the user is attached to the rear end of the left seat arm member 27L.

[0112] In other words, the distance between the second treatment members 35, 36 is such that the second right treatment member 35R, 36R can abut against the user's right buttocks or back of the thigh, for example, and the second left treatment member 35L, 36L can abut against the user's left buttocks or back of the thigh, for example.

[0113] The left and right seat arm members 27R, 27L swing up, down, left and right, so that the left and right second treatment elements 35R, 35L, 36R, 36L can effectively massage the user's thighs (backs of the thighs), buttocks, etc. from below.

[0114] In addition, the left and right seat arm members 27R, 27L are three-dimensionally rocked up and down, front and back, and left and right by the second conversion parts 28R, 28L, but in this embodiment, these are called "up and down, left and right movements." The distance between the pair of left and right seat arm members 27R, 27L may be variable so that it can be adjusted to fit the position of the user's lower limbs, such as the thighs and buttocks.

[0115] The second conversion part 28 is provided on the base end side of the seat arm member 27, and converts the rotational driving force of the second rotating shaft 26 into a rocking motion in the front-rear and left-right directions, and transmits it as a kneading massage action. The second conversion part 28 has a second rotating boss part 37 that rotates integrally with the second rotating shaft 26, a second annular fitting part 39 that is provided on the base end side of the seat arm member 27 and fits onto the second rotating boss part 37, and a second restricting part 40 that restricts the seat arm member 27 from rotating together with the second rotating shaft 26.

[0116] The second rotation shaft 26 penetrates through the inside of the second rotation boss portion 37 in this embodiment, and the outer circumferential surface has a cam surface 38 that is inclined with respect to the second rotation shaft 26. The second rotation boss portion 37 (inclined boss portion) rotates at an incline with respect to the axis of the second rotation shaft 26. Note that the inclined cam surface 38 may be inclined and eccentric with respect to the second rotation shaft 26, for example.

[0117] The second right rotation boss portion 37R is provided on the right side of the second rotation shaft 26. The second left rotation boss portion 37L is provided on the left side of the second rotation shaft 26. The inclinations of the left and right second rotation boss portions 37R, 37L (inclined cam surfaces 38) are inclined in relative opposite directions between the pair of left and right seat arm members 27R, 27L, for example.

[0118] The second annular fitting portion 39 is formed on the base end side of the seat arm member 27, and externally fits the second rotation boss portion 37 in a relatively rotatable state. That is, the inner peripheral diameter of the second annular fitting portion 39 is approximately the same as the outer peripheral diameter of the inclined cam surface 38 of the rotation boss portion 37.

[0119] The second right annular fitting portion 39R fits around the second right rotation boss portion 37R in a relatively rotatable state. The second left annular fitting portion 39L fits around the second left rotation boss portion 37L in a relatively rotatable state. The left and right second annular fitting portions 39R, 39L are arranged so that the pair of left and right seat arm members 27R, 27L are inclined in relatively opposite directions to each other due to the inclination of the left and right second rotation boss portions 37R, 37L.

[0120] The second restricting portion 40 is provided in the second annular fitting portion 39 and restricts the second annular fitting portion 39 from co-rotating with the second rotation boss portion 37. The second restricting portion 40 has a restricting pin 41 provided in the second annular fitting portion 39 and a restricting groove 42 into which the restricting pin 41 is slidably fitted. A second right restricting portion 40R is provided in the second right annular fitting portion 39R. In addition, a second left restricting portion 40L is provided on the base end side of the second left annular fitting portion 39L.

[0121] The restricting pin 41 in this embodiment protrudes forward and backward from the base end of the second annular fitting portion 39. The restricting groove 42 in this embodiment is provided in the case body 43 at a position facing the restricting pin 41. As a result, the seat arm member 27 swings due to the inclined rotation of the second rotating boss portion 37 on which the second annular fitting portion 39 is fitted and the restriction of the co-rotation by the restricting portion 40.

[0122] The seat massage mechanism 4 may be provided with a switching unit that switches the phase of the up / down / left / right rocking motion performed by the pair of left and right seat arm members 27R, 27L when the second rotating shaft 26 rotates forward or backward.

[0123] The seat massage mechanism 4 of this embodiment moves in the front-rear direction along a pair of left and right seat guide rails 44 disposed inside the seat 2 (legs 6). The back guide rails 27 are rail members that are long in the front-rear direction.

[0124] The seat guide rail 44 in this embodiment has a curved shape with the rear end side bulging downward, so that the seat massage mechanism 4 can be housed inside the leg body 6. The seat guide rail 44 may be a straight rail member.
