[Modes for carrying out the invention]

[0018] [Overall configuration of the massage machine] The overall configuration of the massage machine 1 of the present invention will be described below. Figure 1 is a perspective view of the massage machine 1 according to one embodiment of the present invention. Figure 2 is a diagram showing the entire treatment mechanism 60 according to one embodiment of the present invention, where (a) is a front view and (b) is a top view. Figure 3 is a block diagram of the massage machine 1 according to one embodiment of the present invention. In the following explanation, the concept of direction will be the same as the concept of direction as seen from the perspective of the person receiving treatment while seated in the massage machine 1 in use, as shown in Figure 1. Other cases will be explained as appropriate.

[0019] As shown in Figures 1 to 3, the massage machine 1 of the present invention mainly comprises a seat 2 on which the person being treated sits, a backrest 3 that reclines at the rear of the seat 2 to support the upper body of the person being treated, a footrest 4 that swings up and down at the front of the seat 2 to support the legs and / or feet of the person being treated, armrests 5 on both the left and right sides of the seat 2 for the person being treated to rest their arms, and a treatment mechanism 60 (60L, 60R) attached to the side of the backrest 3. The seat 2, backrest 3, footrest 4, and armrests 5 function as body support parts that support the person being treated's body from the rear. Massage parts that perform massage by pressing on the person being treated may be provided in various places on the massage machine 1. In addition, an air cell 40 as a second treatment element that presses on the back of the person being treated is provided inside the backrest 3.

[0020] As shown in Figures 1 and 3, the backrest 3 is configured to recline forward and backward relative to the seat 2 by an actuator 11a located below the seat 2, and can be stopped at any position between the upright position shown in Figure 1 and the reclined position where the backrest surface is approximately horizontal to the floor. The footrest 4 is configured to swing up and down relative to the seat 2 by an actuator 11b located below the seat 2, and can be stopped at any position between the hanging position shown in Figure 1 and the raised position where the legs or feet are supported with the knees extended.

[0021] As shown in Figures 1 and 3, below the seat 2, there is an air supply and exhaust device 10 having a pump 10a and a valve 10b for supplying and exhausting air to the air cells 41L and 41R that constitute the treatment mechanism 60, the extrusion air cells 33L and 33R that constitute the working section A, and the neck air cells 34L and 34R, and a control unit 9 that controls various operations of the massage machine 1. The control unit 9 has a programmable microcontroller or the like, and drives and controls the actuators 11a, 11b, the treatment mechanisms 60L, 60R, and the air supply and exhaust device 10. The controller 12, operated by the person receiving treatment, is electrically connected to the control unit 9. The massage machine 1 operates according to a program (massage course) pre-stored in a memory unit (not shown), as well as according to instructions from the person receiving treatment via the controller 12.

[0022] [Seat structure] As shown in Figure 1, the seat 2 has a seating surface for the person receiving treatment to sit on. Below the seat 2, a leg frame 6 is provided to support the seat 2. The upper surface of the seat 2 may be provided with a back buttock massage section for massaging the back of the person receiving treatment's buttocks and / or thighs. Additionally, the sides of the seat 2 may be provided with side buttock massage sections for massaging the sides of the person receiving treatment's buttocks and / or thighs.

[0023] [Structure of the backrest] As shown in Figure 1, the backrest 3 supports the upper body of the person receiving treatment. The backrest 3 is composed of a rigid back frame 3a (see Figure 11), treatment mechanisms 60L and 60R provided on the sides of the backrest 3, and a cover member 3c that covers the back frame 3a. The back frame 3a is made of metal and / or resin. The back frame 3a also has an opening 3b that opens in the front-to-back direction, formed in the center of the left and right sides, and is roughly gate-shaped when viewed from the front. The cover member 3c covers the opening 3b from the front. Inside the opening 3b, there is a lifting mechanism 83 for raising and lowering the treatment mechanisms 60L and 60R, and a second treatment element 40. The treatment mechanisms 60L and 60R, the lifting mechanism 83, and the second treatment element 40 will be described later.

[0024] [Footrest structure] As shown in Figure 1, the footrest 4 is attached to the seat 2 so as to be able to rotate vertically. The footrest 4 can support the lower leg of the person receiving treatment. A foot support section (not shown) may also be provided to support the sole of the person receiving treatment. The footrest 4 and the foot support section (not shown) may also be equipped with a leg massage section for massaging the lower leg and sole of the foot.

[0025] [Structure of the armrest] As shown in Figure 1, armrests 5 are provided on both the left and right sides of the seat 2 to support the hands and forearms of the person being treated. The armrests 5 are provided with a resting surface, on which the person being treated can rest their hands and forearms. The resting surface may also be provided with an arm massage section for massaging the hands and forearms.

[0026] Figure 4 shows the drive unit 90 of the treatment mechanism 60 according to one embodiment of the present invention (more specifically, the drive unit 90L of the left treatment mechanism 90L), where (a) is a front view and (b) is an exploded perspective view of the drive unit 90. Figure 5 is a perspective view of the left treatment mechanism 60L according to one embodiment of the present invention. Figure 6 shows a part of the left treatment mechanism 60L according to one embodiment of the present invention (more specifically, the state in which the extrusion air cell 33L has been removed from the working part mounting part 39L of the left treatment mechanism 60L), where (a) is a perspective view and (b) is a plan view. Figure 7 shows the working part mounting part 39L attached to the left treatment mechanism 60L according to one embodiment of the present invention, where (a) is a perspective view, (b) is a perspective view of the state in which the extrusion air cell 33L has been removed from the state in (a), (c) is a plan view and (d) is a plan view of the state in which the extrusion air cell 33L has been removed from the state in (c). Figure 8 shows a support member 20 according to one embodiment of the present invention, where (a) is a perspective view and (b) is a plan view. Figure 9 shows an operating part A according to one embodiment of the present invention, where (a) is a perspective view and (b) is a plan view. Figure 10 shows the state in which the neck air cells 34L and 34R have been removed from the state in Figure 9, where (a) is a perspective view and (b) is a plan view. Figure 11 shows the relationship between the treatment mechanism 60 and the second treatment element 40 according to one embodiment of the present invention.

[0027] [Structure of the treatment system] As shown in Figures 1 and 2, the treatment mechanism 60 according to this embodiment is provided in pairs on the left and right sides of the backrest 3. The treatment mechanism 60L is provided on the left side of the backrest 3. The treatment mechanism 60R is provided on the right side of the backrest 3. Furthermore, the treatment mechanism 60 is fitted with an action part A that presses against the neck of the person being treated. The action part A will be described later.

[0028] The treatment mechanism 60 will now be explained. Since the treatment mechanisms 60L and 60R have a symmetrical configuration, the explanation will use the treatment mechanism 60L as an example, and the explanation of the treatment mechanism 60R will be omitted. As shown in Figures 5 and 9, the treatment mechanism 60L mainly consists of a drive unit 90L having an output shaft 44L that extends vertically and rotates when energized, a first treatment element 50L that presses the shoulder of the person being treated from above, an extrusion air cell 33L that constitutes an action part A that presses the neck of the person being treated, a treatment element holder 35L that holds at least the first treatment element 50L, and a swing mechanism C for swinging the treatment element holder 35L. By driving the drive unit 90L, the treatment element holder 35L can oscillate the first treatment element 50L and the working part A via the oscillating mechanism C. The oscillating mechanism C will be described later.

[0029] [Composition of the first treatment unit] As shown in Figures 5 and 6, the first treatment element 50L is attached to the treatment element holder 35L. More specifically, the first treatment element 50L has a roughly cylindrical shape with a rounded tip and protrudes downward from the top. The first treatment element 50L is attached to the treatment element holder 35L. More specifically, the base end (upper side in the vertical direction) of the first treatment element 50L is attached to the lower surface of the treatment element holder 35L. In other words, the first treatment element 50L is provided so as to protrude downward from the lower surface of the treatment element holder 35L. This allows the first treatment element 50L to press down on the shoulders of the person being treated while seated on the seat 2 from above.

[0030] [Configuration of the treatment device holder] The treatment element holder 35L is for holding the first treatment element 50L. The treatment element holder 35L has a roughly oval shape with a predetermined thickness. The treatment element holder 35L is attached to one end (right side in the left-right direction) of the retaining plate 36L. More specifically, the upper surface of the treatment element holder 35L is attached to the lower surface of the retaining plate 36L (see Figures 2(a) and 5). The first treatment element 50L is attached to the lower surface of the treatment element holder 35L. In other words, the positional relationship between the retaining plate 36L, the treatment element retaining part 35L, and the first treatment element 50L is configured such that, from top to bottom, they are the retaining plate 36L, the treatment element retaining part 35L, and the first treatment element 50L (see Figures 2(a) and 5).

[0031] The retaining plate 36L is attached to the output shaft 44L via a swash plate cam 51L that restricts the oscillation direction of the treatment element retaining part 35L. Since the treatment element retaining part 35L is attached to the retaining plate 36L, when the output shaft 44L rotates and the retaining plate 36L oscillates, the treatment element retaining part 35L also oscillates together with the retaining plate 36L. The retaining plate 36L and the swash plate cam 51L will be described later.

[0032] [Configuration of the drive unit] Figure 4 shows the drive unit 90L of the treatment mechanism 60L on the left side. As shown in Figure 4, the drive unit 90L consists of a motor M1, a circuit board 46L that controls the rotation of the motor M1, a reduction mechanism 93L that reduces the rotation of the motor M1 and transmits it to the treatment mechanism 60L, and an output shaft 44L that extends in the vertical direction. More specifically, the motor M1 is mounted downwards to the circuit board 46L such that the drive shaft extending from the motor M1 extends downwards. In other words, the axial direction of the drive shaft of the motor M1 and the axial direction of the output shaft 44L are in the same direction (vertical direction).

[0033] The drive shaft is equipped with a worm gear 47L for reducing the rotation of the drive shaft and transmitting it to the output shaft 44L. The worm gear 47L meshes with a first gear 48L whose left-right direction is axial. Above the output shaft 44L is a second gear 70L. The first gear 48L meshes with the second gear 70L. In other words, the worm gear 47L meshes with the first gear 48L, and the first gear 48L meshes with the second gear 70L. The rotation of the drive shaft is reduced in the order of worm gear 47L, first gear 48L, and second gear 70L, and transmitted to the output shaft 44L. The worm gear 47L, first gear 48L, and second gear 70L function as a reduction gear mechanism 93L to reduce the rotation of the motor M1 and transmit it to the treatment mechanism 60L. The reduction gear mechanism 93L is covered by a case 45L.

[0034] A swash plate cam 51L is mounted below the output shaft 44L. More specifically, a pin 49L is inserted below the output shaft 44L in a direction perpendicular to the output shaft 44L. The swash plate cam 51L is attached to the output shaft 44L via the pin 49L. In other words, as the output shaft 44L rotates, the pin 49L inserted through the output shaft 44L also rotates. Since the swash plate cam 51L is attached to the output shaft 44L via the pin 49L, the swash plate cam 51L also rotates in conjunction with the rotation of the output shaft 44L. Therefore, the swash plate cam 51L can rotate in sync with the rotation of the output shaft 44L without slipping.

[0035] The swash plate cam 51L consists of a cam body 43L and a bearing 42L mounted at an angle to the cam body 43L. The swash plate cam 51L constitutes part of the oscillating mechanism C. The swash plate cam 51L is mounted eccentrically with respect to the output shaft 44L. A retaining plate 36L is attached to the bearing 42L, which is mounted at an angle to the cam body 43L. In other words, the retaining plate 36L can achieve three-dimensional oscillating motion, including vertical oscillation by the bearing 42L, as well as forward, backward, left, and right oscillation due to eccentricity, through the swash plate cam 51L.

[0036] The swash plate cam 51L is mounted to the retaining plate 36L. More specifically, the swash plate cam 51L is mounted by being inserted through a hole 37L provided in the retaining plate 36L. A cover 88 is attached around the hole 37L to prevent the swash plate cam 51L from being exposed (see Figure 5). Since the swashplate cam 51L is attached to the retaining plate 36L, the retaining plate 36L also oscillates as the swashplate cam 51L rotates. The retaining plate 36L is attached to the first treatment element 50L, which is attached via the treatment element holding part 35L, and to the action part A (more specifically, the action part mounting part 39L) that presses against the neck of the person being treated. Therefore, as the retaining plate 36L oscillates, the first treatment element 50L and the action part A also oscillate together. The action part A will be described later.

[0037] [Configuration of the rocking mechanism] Let me explain the oscillating mechanism C. The oscillating mechanism C is for oscillating the treatment element holder 35L. The oscillating mechanism C is composed of multiple components. As shown in Figure 5, the oscillating mechanism C consists of a swash plate cam 51L, a treatment element holder 35L to which the swash plate cam 51L is attached, a bracket 55L attached to the treatment element holder 35L, and a link member 57L attached to the bracket 55L.

[0038] The oscillating mechanism C is supported by two parts: a link member 57L and an output shaft 44L. The link member 57L is a cylindrical rod-shaped member. More specifically, it is a ball joint with a spherical end. The other end of the link member 57L is provided with a hole (not shown) that extends in the left-right direction. One end of the link member 57L is attached to the drive unit 90L, and the other end of the link member 57L is attached to the bracket 55L with the left-right direction as the axial direction via a pin 89 inserted through the hole (not shown).

[0039] Bracket 55L is composed of a concave, plate-like member with both sides bent upwards when viewed from the front, and both sides have a roughly triangular shape when viewed from the side. A metal support plate 56L is attached to the bottom surface of bracket 55L to receive the reaction force of the air cell 41L. Bracket 55L has two holes on its side. One is located at the top end of bracket 55L, and the other is located at the rear end of bracket 55L. The hole at the upper end of bracket 55L has the same diameter as the hole at the other end of link member 57L. By inserting a pin 89 through these two holes, bracket 55L can be pivoted vertically using pin 89 as a pivot point. By inserting a pin (not shown) through a hole (not shown) at the rear end of bracket 55L, bracket 55L can be pivoted vertically using pin (not shown) as a pivot point. In short, bracket 55L is supported at two pivot points. The support plate 56L will be discussed later.

[0040] In other words, when the drive unit 90L is driven and the output shaft 44L is rotated, the swash plate cam 51L rotates. A bearing 42L is mounted at an angle on the cam body 43L that makes up the swash plate cam 51L. A retaining plate 36L is attached to the bearing 42L that is mounted at an angle. Therefore, the treatment element retaining part 35L attached to the retaining plate 36L swings together with the swing of the retaining plate 36L. More specifically, it swings in the vertical direction. Furthermore, because the cam body 43L that makes up the swash plate cam 51L is eccentric, it can also swing in the front-back, back-and-forth, left-and-right directions. In other words, the retaining plate 36L swings in three dimensions, both vertically and in the front-back, back-and-forth, left-and-right directions.

[0041] The oscillation of the retaining plate 36L will now be explained. The rear end of the bracket 55L is attached to the retaining plate 36L. Therefore, when the retaining plate 36L swings forward, the bracket 55L attached to the retaining plate 36L also swings forward together with it. At this time, since the link member 57L is attached to the upper end of the bracket 55L, the forward oscillation of the bracket 55L is restricted. Furthermore, since the support plate 56L is attached to the bracket 55L, the oscillation of the support plate 56L is also restricted.

[0042] Specifically, when the retaining plate 36L is swung forward, the bracket 55L attached to the retaining plate 36L swings forward, and partway through, the front end of the bracket 55L swings downward. This is because the rear end of the bracket 55L is attached to the retaining plate 36L, and the other end of the link member 57L is attached to the upper end of the bracket 55L via a pin 89 that extends in the left-right direction. The link member 57L is designed to swing forward using one end (ball joint) of the link member 57L as a pivot point. Therefore, when the retaining plate 36L swings forward, the bracket 55L also swings forward in conjunction with the swing of the retaining plate 36L. At this time, since the link member 57L is attached to the upper end of the bracket 55L, the range of motion of the retaining plate 36L is also restricted by the ball joint of the link member 57L. Because the range of motion of the bracket 55L is restricted by the link member 57L, once the link member 57L has swung forward as far as it can go, the bracket 55L cannot swing any further forward. However, since the retaining plate 36L continues to swing forward, the bracket 55L is pushed forward by the retaining plate 36L. As a result, the front end of the bracket 55L swings downward with the pin 89 as the pivot point. In addition, the air cell 41L, which is attached via the support plate 56L, also swings forward along with the swing of the bracket 55L.

[0043] Furthermore, when the retaining plate 36L swings backward, the bracket 55L attached to the retaining plate 36L also swings backward. At this time, since the link member 57L is attached to the upper end of the bracket 55L, the backward swinging of the bracket 55L is restricted. And since the support plate 56L is attached to the bracket 55L, the swinging of the support plate 56L is also restricted.

[0044] Specifically, when the retaining plate 36L is swung backward, the bracket 55L attached to the retaining plate 36L swings backward, and partway through, the front end of the bracket 55L swings upward. This is because the rear end of the bracket 55L is attached to the retaining plate 36L, and the other end of the link member 57L is attached to the upper end of the bracket 55L via a pin 89 that extends in the left-right direction. The link member 57L is designed to swing backward using one end (ball joint) as a pivot point. Therefore, when the retaining plate 36L swings backward, the bracket 55L also swings backward along with the swing of the retaining plate 36L. At this time, since the link member 57L is attached to the upper end of the bracket 55L, the range of motion of the retaining plate 36L is also restricted by the ball joint. Because the range of motion of the bracket 55L is restricted by the link member 57L, once the link member 57L has swung as far backward as it can go, the bracket 55L cannot swing any further backward. However, since the retaining plate 36L continues to swing backward, the bracket 55L is pulled back backward. As a result, the front end of the bracket 55L swings upward with the pin 89 as the pivot point. In addition, the air cell 41L, which is attached via the support plate 56L, also swings backward along with the swing of the bracket 55L.

[0045] [Air cell configuration] An air cell 41L is attached to the bracket 55L for pressing the shoulder of the person being treated from the front. More specifically, the upper end of the bracket 55L is pivotably attached to the drive unit 90L via a link member 57L. The rear end of the bracket 55L is attached to the treatment element holder 35L so as to be pivotable in the vertical direction with the left-right direction as the axial direction. A metal support plate 56L is attached to the front of the lower surface of the bracket 55L to receive the reaction force of the air cell 41L. The air cell 41L is attached to the lower surface of this support plate 56L. In this way, when the air cell 41L inflates, the support plate 56L can receive the reaction force of the air cell 41L, and the shoulder of the person being treated can be pressed from the front.

[0046] [Configuration of the working part] As shown in Figure 9, the working part A is composed of multiple members. More specifically, the working part A consists of neck air cells 34L and 34R located at the frontmost position in the front-rear direction, a support member 20 to which the neck air cells 34L and 34R are attached, extruded air cells 33L and 33R located on the back of the support member 20, and working part mounting parts 39L and 39R to which the extruded air cells 33L and 33R are attached. A thin plate-shaped PE sheet 20a for attaching the neck air cells 34L and 34R is attached to the front of the support member 20. The working part A is composed of elastic air cells. By composing the working part A with air cells, it can apply pressure over a surface, allowing for a soft and comfortable pressure sensation on the person receiving treatment.

[0047] As shown in Figure 2, the working part A is mounted on the base end side of the first treatment elements 50L and 50R in the vertical direction (see Figure 2(a)) and positioned forward of the first treatment elements 50L and 50R (see Figure 2(b)). More specifically, the working part A is mounted to the working part mounting parts 39L and 39R which are mounted above the left and right treatment mechanisms 60L and 60R. By attaching the working part A to the base end side of the first treatment elements 50L and 50R in the vertical direction, and by positioning the working part A in front of the first treatment elements 50L and 50R, interference between the working part A and the first treatment elements 50L and 50R can be prevented. Furthermore, compared to the case where the working part A is positioned behind the first treatment elements 50L and 50R, there is no need to ensure sufficient expansion of the working part A, thus preventing the working part A from becoming larger.

[0048] [Structure of the support members] As shown in Figure 8, the support member 20 has a predetermined thickness in the front-rear direction. The support member 20 is integrally formed across the left-right direction and has a rectangular shape that is elongated in the left-right direction. By integrally forming the support member 20 (acting part A) across the left-right direction, the neck of the person receiving treatment can be stably supported. The left end of the support member 20 is attached to the acting part mounting part 39L of the treatment mechanism 60L, and the right end of the support member 20 is attached to the acting part mounting part 39R of the treatment mechanism 60R. In other words, the support member 20 is installed so as to be located between the left and right treatment mechanisms 60L and 60R.

[0049] The support member 20 is curved in a convex shape from front to back in a plan view (see Figure 8(b)). The convex curved portion is designed to allow the neck (back) of the person receiving treatment to conform to it. In other words, the neck can be stably supported by the support member 20. The support member 20 is also made of a flexible material. Examples of flexible materials include polyurethane and elastomer. These are just examples, and any material that is flexible enough not to damage the support member 20 when the treatment mechanisms 60L and 60R are in operation is acceptable.

[0050] The support member 20 is provided with a T-shaped groove F1. More specifically, the groove F1 extends vertically from the upper center of the support member 20 downwards, and horizontally from near the center of the support member 20. The intake and exhaust ports (not shown) of the neck air cells 34L and 34R, and hoses (not shown) for supplying and exhausting air to the neck air cells 34L and 34R are fitted into the groove F1. By fitting the intake and exhaust ports of the neck air cells 34L and 34R and the hoses into the groove F1, the back surfaces of the neck air cells 34L and 34R and the front surfaces of the support member 20 become flush, allowing the neck air cells 34L and 34R to be attached to the support member 20 without any gaps.

[0051] The neck air cells 34L and 34R are attached to the front surface of the support member 20. More specifically, the neck air cells 34L and 34R are attached to the support member 20 via holes E5. As a result, the neck air cells 34L and 34R expand so that their left and right outer sides rise up, with holes E5 as the pivot point. In other words, the expansion and contraction of the neck air cells 34L and 34R allows them to grip the neck of the person being treated from both sides.

[0052] The neck air cells 34L and 34R are designed to apply pressure to the neck of the patient (more specifically, the back of the neck). The neck air cells 34L and 34R are connected by separate hoses (see Figure 3). Therefore, the neck air cells 34L and 34R can be inflated and deflated independently on the left and right sides. For example, one side may be inflated, or both sides may be inflated simultaneously. The 34L and 34R neck air cells can also be connected with a single common hose. More specifically, this can be achieved by using a hose with a bifurcated end, connecting one end to the 34L neck air cell and the other end to the 34R neck air cell. In this way, the 34L and 34R neck air cells can be inflated and deflated simultaneously on both sides using a single hose.

[0053] [Configuration of the mounting part for the working part] The mounting section 39L of the working part will now be described. Note that the mounting section 39R has the same configuration as the mounting section 39L, so its description will be omitted. As shown in Figure 7, the mounting section 39L is made up of a metal plate-like member bent into an L shape. More specifically, the mounting section 39L is made up of a bottom plate 32L and a front plate 31L that rises upward from the front of the bottom plate 32L.

[0054] The base plate 32L is provided with holes E2 (two in this embodiment), and is fixed by screws to the retaining plate 36L attached to the upper surface of the treatment element holding part 35L. In other words, the working part mounting part 39L does not swing independently, but is configured to swing together with the treatment mechanism 60L. Therefore, the swing trajectory of the working part A and the swing trajectory of the first treatment element 50 are made to coincide. The retaining plate 36L will be described later.

[0055] Multiple holes are provided in the front plate 31L. A hole E1 is provided near the center of the front plate 31L for inserting the intake and exhaust ports of the extruded air cell 33L (see Figure 7(b)). By inserting the intake and exhaust ports of the extruded air cell 33L through hole E1 (see Figure 7(c)), the back of the extruded air cell 33L and the front of the front plate 31L can be attached without any gaps. Two holes E3 are provided on each side of the front plate 31L, one above the other (a total of four). Holes are also provided on both sides of the extruded air cell 31L, similar to holes E3. Therefore, the front plate 31L and the extruded air cell 33L can be fixed together by screws through the holes E3. Since the four corners of the extruded air cell 33L are fixed to the front plate 31L, it expands parallel to the surface of the front plate 31L.

[0056] The extrusion air cells 33L and 33R are for extruding the support member 20. The extrusion air cells 33L and 33R are connected by separate hoses (see Figure 3). Therefore, the extrusion air cells 33L and 33R can be inflated and deflated independently on the left and right sides. For example, only one side may be inflated, or both sides may be inflated simultaneously.

[0057] [Configuration of the retaining plate] Figure 6 shows a part of the left treatment mechanism 60L according to one embodiment of the present invention, where (a) is a perspective view and (b) is a plan view. More specifically, it is a diagram in which the drive unit 90L and the oscillating mechanism C are omitted. As shown in Figure 6, the retaining plate 36L has a roughly boomerang shape, sloping forward from right to left. The operating part mounting part 39L is screwed to the right side of the retaining plate 36L. The left side of the retaining plate 36L is provided with a mounting hole 37L for inserting the swash plate cam 51L. The bracket 55L, which constitutes the swing mechanism C, is attached to the front end of the retaining plate 36L so as to be able to swing up and down with the left-right direction as the axial direction. Note that the retaining plate 36R has the same configuration as the retaining plate 36L, so its description is omitted.

[0058] [Composition of the second treatment room] As shown in Figures 1 and 11, the treatment mechanism 60 is equipped with a second treatment element 40 that presses against the back of the person being treated. The second treatment element 40 is composed of an air cell that expands and contracts with the supply and exhaust of air. More specifically, the second treatment element 40 is attached near the center of a frame 60a that extends in the left-right direction. Preferably, a second treatment element mounting plate (not shown) is provided on the back of the second treatment element 40 to support the second treatment element 40 from behind. By providing the second treatment element mounting plate (not shown), it can be used to receive the reaction force when the second treatment element 40 expands.

[0059] Since the second treatment element 40 is attached to the frame 60a that supports the treatment mechanisms 60L and 60R, when the lifting mechanism 83 is driven, the second treatment element 40 also moves up and down together with the treatment mechanisms 60L and 60R. In this way, the position of the second treatment element 40 can be adjusted simultaneously by adjusting the position of the treatment mechanisms 60L and 60R.

[0060] In this embodiment, only one air cell, which is the second treatment element 40, is provided, but multiple air cells may be provided. For example, two air cells may be provided in a pair, one on the left and one on the right, or four air cells may be provided in a pair, one on the left and one on the right, and one on the top and one on the bottom. In that case, it is preferable that each air cell can be inflated and deflated individually. This allows for a variety of massages to be performed on the back of the person being treated.

[0061] [Configuration of the lifting mechanism] Figure 11 is a diagram showing the relationship between the treatment mechanism 60 and the second treatment element 40 according to one embodiment of the present invention. As shown in Figure 11, the treatment mechanisms 60L and 60R are capable of moving up and down. More specifically, the treatment mechanisms 60L and 60R are attached to a lifting mechanism 83. The lifting mechanism 83 consists of a threaded rod 80, a lifting motor M2, a belt member 82 for transmitting the rotation of the lifting motor M2, and a gear 81 located below the threaded rod 80 and rotated by the belt member 82. The left treatment mechanism 60L and the right treatment mechanism 60R are connected by a frame 60a that extends in the left-right direction. The central part of the frame 60a is attached to the threaded rod 80.

[0062] The left and right treatment mechanisms 60L and 60R are connected by a frame 60a, so that by rotating the lifting motor M2, the treatment mechanisms 60L and 60R move up and down. Specifically, when the lifting motor M2 is rotated, the rotation is transmitted to the gear 81 via the belt member 82. Since the gear 81 is attached to the threaded rod 80, the threaded rod 80 also rotates as the gear 81 rotates. As the threaded rod 80 rotates, the treatment mechanisms 60L and 60R attached to the threaded rod 80 move upward or downward. By configuring the treatment mechanisms 60L and 60R to be movable up and down by the lifting mechanism 83, the treatment mechanisms 60L and 60R can be adjusted to the shoulder position of the person being treated while seated on the seat 2.

[0063] Figure 12 shows a treatment mechanism 60 according to one embodiment of the present invention, where (a) is a front view and (b) is a top view. More specifically, it shows the state in which the left first treatment element 50L and the right first treatment element 50R are attached to the treatment element holders 35L and 35R such that the separation distance W1 between them is greater than the separation distance W2 between the left and right pair of working parts A, neck air cells 34L and neck air cells 34R. Figure 13 shows a treatment mechanism 60 according to one embodiment of the present invention, where (a) is a front view and (b) is a top view. More specifically, it shows the state in which the left first treatment element 50L and the right first treatment element 50R are attached to the treatment element holders 35L and 35R such that the left-right distance W3 between them is greater than the left-right distance W4 between the left and right pair of working parts A. Figure 14 shows a treatment mechanism 60 according to one embodiment of the present invention, where (a) is a front view and (b) is a top view. More specifically, this diagram shows the state in which the left first treatment element 50L and the right first treatment element 50R are attached to the treatment element holders 35L and 35R such that their mounting positions P5 are located further outward in the left-right direction than the mounting positions P6 of the left and right working parts A.

[0064] [Relationship between the first treatment device and the area of ​​action 1] Figure 12 shows the state in which the left first treatment element 50L and the right first treatment element 50R are attached to the treatment element holders 35L and 35R such that the separation distance W1 between them is greater than the separation distance W2 between the neck air cells 34L and 34R of the left and right pair of working parts A. For clarity, virtual dashed lines P1 and P2 are drawn to show the separation distances W1 and W2. Separation distance W1 represents the distance between the left and right virtual dashed lines P1, and separation distance W2 represents the distance between the left and right virtual dashed lines P2.

[0065] As shown in Figure 12, the first treatment element 50L is mounted at a position away from the center O of the treatment mechanism 60, moving to the left. The first treatment element 50R is mounted at a position away from the center O of the treatment mechanism 60, moving to the right. The distance between the inner line (virtual dashed line P1) of the left first treatment element 50L (right side in the left-right direction) and the inner line (virtual dashed line P1) of the right first treatment element 50R (left side in the left-right direction) is the separation distance W1.

[0066] Furthermore, the neck air cell 34L of the action unit A is mounted at a position away from the center O of the treatment mechanism 60 toward the left. The neck air cell 34R of the action unit A is mounted at a position away from the center O of the treatment mechanism 60 toward the right. The distance between the inner line (virtual dashed line P2) of the left neck air cell 34L (right side in the left-right direction) and the inner line (virtual dashed line P2) of the right neck air cell 34R (left side in the left-right direction) is the separation distance W2.

[0067] The separation distances W1 and W2 are in the relationship W1 > W2. By making the separation distances W1 > W2, when the left and right first treatment elements 50L and 50R press on the shoulders of the person being treated from above, the neck of the person being treated can also be pressed simultaneously by the neck air cells 34L and 34R of the working part A. Note that the separation distances W1 and W2 are examples only and are not limited to these. The separation distance W2 of the neck air cells 34L and 34R of the working part A may be changed as appropriate to match the left-right width of the patient's neck (wider for patients with thick necks, and narrower for patients with thin necks), and the separation distance W1 of the first treatment elements 50L and 50R may be changed to match the left-right width of the patient's shoulders (wider for patients with broad shoulders, and narrower for patients with narrow shoulders). By changing the separation distances W1 and W2, the device can be adapted to the patient's physique.

[0068] [Relationship between the first treatment device and the area of ​​action, part 2] Figure 13 shows the state in which the left first treatment element 50L and the right first treatment element 50R are attached to the treatment element holders 35L and 35R such that the distance W3 between them is greater than the distance W4 between the left and right neck air cells 34L and 34R of the pair of working parts A. For clarity, virtual dashed lines P3 and P4 have been drawn to represent the left-right spacing W3 and W4. The left-right spacing W3 indicates the distance between the left and right virtual dashed lines P3, and the left-right spacing W4 indicates the distance between the left and right virtual dashed lines P4.

[0069] As shown in Figure 13, the first treatment element 50L is mounted at a position away from the center O of the treatment mechanism 60, moving to the left. The first treatment element 50R is mounted at a position away from the center O of the treatment mechanism 60, moving to the right. The distance between the center line of the left first treatment element 50L (virtual dashed line P3) and the center line of the right first treatment element 50R (virtual dashed line P3) is the left-right distance W3.

[0070] Furthermore, the neck air cell 34L of the action unit A is mounted at a position away from the center O of the treatment mechanism 60 toward the left. The neck air cell 34R of the action unit A is mounted at a position away from the center O of the treatment mechanism 60 toward the right. The distance between the center line of the left neck air cell 34L (virtual dashed line P4) and the center line of the right neck air cell 34R (virtual dashed line P4) is the left-right distance W4.

[0071] The left-right spacing W3 and the left-right spacing W4 are in the relationship W3 > W4. By setting the left-right spacing to W3 > W4, when the left and right first treatment elements 50L and 50R press on the shoulder area of ​​the person being treated from above, the neck area of ​​the person being treated can also be pressed simultaneously by the neck air cells 34L and 34R of the action part A. Note that the left-right spacing W3 and W4 are examples only and are not limited to these. The left-right spacing W4 of the neck air cells 34L and 34R of the working part A may be changed as appropriate to match the left-right width of the patient's neck (wider for patients with thicker necks, and narrower for patients with thinner necks), and the left-right spacing W3 of the first treatment element 50L and 50R may be changed to match the left-right width of the patient's shoulders (wider for patients with broad shoulders, and narrower for patients with narrow shoulders). By changing the left-right spacing W3 and W4, the device can be adapted to the patient's physique.

[0072] [Relationship between the first treatment device and the area of ​​action 3] Figure 14 shows the state in which the left first treatment element 50L and the right first treatment element 50R are attached to the treatment element holders 35L and 35R such that their mounting positions P5 are located outward in the left-right direction from the mounting positions P6 of the left and right pair of working parts A, namely the neck air cells 34L and 34R. The virtual dashed line P5 indicates the mounting position of the left first treatment device 50L, W5 indicates the distance from the center O to the mounting position of the left first treatment device 50L (virtual dashed line P5), and W6 indicates the distance from the center O to the mounting position of the left neck air cell 34L (virtual dashed line P6).

[0073] As shown in Figure 14, the virtual dashed line P5 indicates the mounting position of the first treatment element 50L. The first treatment element 50L is attached to the retaining plate 36L via the treatment element retaining part 35L. More specifically, the center of the first treatment element 50L is attached so that it aligns with the center of the diagonal intersection of four holes E4 provided near the rear end of the retaining plate 36L. The distance from the center O to the center of the first treatment element 50L at this time is W5. The virtual dashed line P6 indicates the mounting position of the neck air cell. The neck air cell 34L is mounted so as to open outward in the left-right direction with the center O as the pivot point. More specifically, it is mounted so that the left-right inward side acts as the pivot point on the thin plate-shaped PE sheet 20a (see Figure 10) attached to the front surface of the support member 20.

[0074] The distance from the center O to the mounting position (virtual dashed lines P5, P6) is W5 > W6. By making the distance from the center O to the mounting position (virtual dashed lines P5, P6) W5 > W6, when the left and right first treatment elements 50 press down on the shoulders of the person being treated from above, the neck air cells 34L, 34R of the working part A can simultaneously press down on the neck of the person being treated. Note that the distances W5 and W6 from the center O to the mounting position (virtual dashed lines P5 and P6) are examples only and are not limited to these. The distance W6 from the center O to the mounting position (virtual dashed line P6) for the neck air cells 34L and 34R of the working part A may be changed as appropriate to match the width of the neck of the person being treated (wider for people with thick necks, and narrower for people with thin necks), and the distance W5 from the center O to the mounting position (virtual dashed line P5) for the first treatment elements 50L and 50R may be changed (wider for people with broad shoulders, and narrower for people with narrow shoulders). By changing the distances W5 and W6 from the center O to the mounting position (virtual dashed lines P5 and P6), it is possible to adjust to the physique of the person being treated.

[0075] Figure 15 shows the oscillation trajectories V1 to V4 of the first treatment element 50 and the working part A. Note that oscillation trajectories V1 to V4 are excerpts of the state when the output shafts 44L and 44R are rotated to 0 degrees, 90 degrees, 270 degrees, and 360 degrees, and by oscillating the first treatment element, it draws a circular oscillation trajectory (a series of movements of oscillation trajectories V1 to V4). In addition, to make the oscillation trajectories V1 to V4 easier to understand, some parts of the working part A (support member 20, extrusion air cells 33L and 33R, neck air cells 34L and 34R) have been omitted.

[0076] The oscillation trajectories V1 to V4 of the working part A coincide with the oscillation trajectories V1 to V4 of the first treatment element 50. The working part A is attached to the working part mounting parts 39L and 39R, and the working part mounting parts 39L and 39R are attached to the upper surfaces of the retaining plates 39L and 39R. Treatment element retaining parts 35L and 35R are attached to the lower surfaces of the retaining plates 39L and 39R, and the first treatment elements 50L and 50R, which protrude downward, are attached to the treatment element retaining parts 35L and 35R. In other words, both the working part A and the first treatment elements 50L and 50R are attached to the treatment element holder parts 35L and 35R.

[0077] When the drive units 90L and 90R are driven, the treatment element holders 35L and 35R oscillate via the oscillating mechanism C. Since the action part A and the first treatment elements 50L and 50R are attached to the treatment element holders 35L and 35R, the action part A and the first treatment elements 50L and 50R oscillate in accordance with the oscillating motion of the treatment element holders 35L and 35R. In other words, the oscillation trajectories V1 to V4 in the working part A coincide with the oscillation trajectories of the treatment element holders 35L and 35R, and the oscillation trajectories V1 to V4 in the first treatment elements 50L and 50R coincide with the oscillation trajectories V1 to V4 in the treatment element holders 35L and 35R. By making the oscillation trajectories V1 to V4 of the working part A and the first treatment elements 50L and 50R coincide, the working part A can be made to oscillate in accordance with the oscillation of the first treatment elements 50L and 50R.

[0078] The oscillating motion of the treatment mechanism 60 will now be explained. Note that the rotation direction of the output shaft 44L of the left treatment mechanism 60L and the rotation direction of the output shaft 44R of the right treatment mechanism 60R are opposite to each other. As described above, the working part A (more specifically, the working part mounting parts 39L, 39R) and the first treatment element 50L, 50R are integrally attached to the treatment element holding parts 35L, 35R. The rotation reference (0 degrees) is defined as the state in which the treatment element holding parts 35L, 35R are positioned furthest forward relative to the output shafts 44L, 44R. At this time, the treatment element holding parts 35L, 35R are in a position where, when viewed from the front, the front side is tilted upward and the rear side is tilted downward (see upper left of Figure 15).

[0079] From this state, when the drive unit 90L is driven to rotate the output shaft 44L by 90 degrees (from 0 degrees to 90 degrees), the treatment element holder 35L moves so that the left side in the left-right direction tilts significantly downward. More specifically, it assumes a posture where the left side is tilted downward and the right side is tilted upward. At this time, the action part mounting part 39L and the first treatment element 50L each trace an oscillation trajectory V1 in accordance with the oscillation of the treatment element holder 35L. On the other hand, when the drive unit 90R is driven to rotate the output shaft 44R by 90 degrees (from 0 degrees to 90 degrees), the treatment element holder 35R moves so that the right side in the left-right direction tilts significantly downward. More specifically, it assumes a posture where the right side is tilted downward and the left side is tilted upward. At this time, the action part mounting part 39R and the first treatment element 50R each trace an oscillation trajectory V1 in accordance with the oscillation of the treatment element holder 35R. In other words, the first treatment elements 50L and 50R of the left and right treatment mechanisms 60L and 60R move in a direction that brings them closer to each other (resulting in the state shown in the lower left of Figure 15).

[0080] From this state, when the drive unit 90L is driven to rotate the output shaft 44L by 90 degrees (to a state where the output shaft 44L has been rotated from 0 degrees to 180 degrees), the treatment element holder 35L moves such that the front side in the front-rear direction is tilted significantly downward. More specifically, it assumes a posture where the front side is tilted downward and the rear side is tilted upward. At this time, the action part mounting part 39L and the first treatment element 50L each trace a swing trajectory V2 in accordance with the swing of the treatment element holder 35L. On the other hand, when the drive unit 90R is driven to rotate the output shaft 44R by 90 degrees (to a state where the output shaft 44L has been rotated from 0 degrees to 180 degrees), the treatment element holder 35R moves such that the front side in the front-rear direction is tilted significantly downward. More specifically, it assumes a posture where the front side is tilted downward and the rear side is tilted upward. At this time, the working part mounting part 39R and the first treatment element 50R each trace a swinging trajectory V2 in accordance with the swinging of the treatment element holding part 35R. In other words, the first treatment elements 50L and 50R of the left and right treatment mechanisms 60L and 60R move in directions away from each other (resulting in the state shown in the lower right of Figure 15).

[0081] From this state, when the drive unit 90L is driven to rotate the output shaft 44L by 90 degrees (to a state where the output shaft 44L has been rotated from 0 degrees to 270 degrees), the treatment element holder 35L moves so that the right side in the left-right direction tilts significantly downward. More specifically, it assumes a posture where the right side is tilted downward and the left side is tilted upward. At this time, the action part mounting part 39L and the first treatment element 50L each trace a swing trajectory V3 in accordance with the swing of the treatment element holder 35L. On the other hand, when the drive unit 90R is driven to rotate the output shaft 44R by 90 degrees (to a state where the output shaft 44L has been rotated from 0 degrees to 270 degrees), the treatment element holder 35R moves so that the left side in the left-right direction tilts significantly downward. More specifically, it assumes a posture where the left side is tilted downward and the right side is tilted upward. At this time, the working part mounting part 39R and the first treatment element 50R each trace a swinging trajectory V3 in accordance with the swinging of the treatment element holding part 35R. In other words, the first treatment elements 50L and 50R of the left and right treatment mechanisms 60L and 60R move in directions away from each other (resulting in the state shown in the upper right of Figure 15).

[0082] From this state, when the drive unit 90L is driven to rotate the output shaft 44L by 90 degrees (to a state where the output shaft 44L has been rotated from 0 degrees to 360 degrees), the treatment element holder 35L moves such that the rear side in the front-rear direction is tilted significantly downward. More specifically, it assumes a posture where the rear side is tilted downward and the front side is tilted upward. At this time, the action part mounting part 39L and the first treatment element 50L each trace a swing trajectory V4 in accordance with the swing of the treatment element holder 35L. On the other hand, when the drive unit 90R is driven to rotate the output shaft 44R by 90 degrees (to a state where the output shaft 44L has been rotated from 0 degrees to 360 degrees), the treatment element holder 35R moves such that the rear side in the front-rear direction is tilted significantly downward. More specifically, it assumes a posture where the rear side is tilted downward and the front side is tilted upward. At this time, the working part mounting part 39R and the first treatment element 50R each trace a swinging trajectory V4 in accordance with the swinging of the treatment element holding part 35R. In other words, the first treatment elements 50L and 50R of the left and right treatment mechanisms 60L and 60R move in a direction that brings them closer to each other (resulting in the state shown in the upper left of Figure 15).

[0083] Figure 16 shows an operating part A1 according to another embodiment of the present invention, where (a) is a perspective view and (b) is a perspective view showing the state in (a) with the neck air cells 34L and 34R removed. Figure 17 shows an operating part A2 according to another embodiment of the present invention, where (a) is a perspective view and (b) is a plan view.

[0084] [Other embodiments] In this embodiment, we have described a case in which an action part A having a support member 20 integrally formed in the left-right direction is attached to the treatment mechanism 60. However, the shape of the support member 20 is just an example and is not limited to this. It may also be configured as shown in action parts A1 and A2. For example, as shown in Figure 16(a), protrusions 99L and 99R may be attached to the front surface of the neck air cells 34L and 34R to apply point pressure to the neck of the person being treated. By attaching the protrusions 99L and 99R to the neck air cells 34L and 34R, it is possible to provide the person being treated with a stronger pressure stimulus compared to the pressure applied by the neck air cells 34L and 34R alone. Specifically, by inflating the neck air cells 34L and 34R, the protrusions 99L and 99R are pushed forward and come into contact with the person being treated. This increases the pressure stimulus applied to the neck of the person being treated.

[0085] Alternatively, as shown in Figure 16(b), the neck air cells 34L and 34R may be removed, and protrusions 99L and 99R for applying point pressure to the neck of the person being treated may be attached to the front surface of the support member 20. By attaching the protrusions 99L and 99R to the support member 20, the pressure changes from surface pressure by the neck air cells 34L and 34R to point pressure by the protrusions 99L and 99R, thus providing a stronger pressure stimulus to the person being treated with a simpler configuration.

[0086] Furthermore, as shown in Figures 17(a) and 17(b), the support member 20 may be divided into left and right halves. By dividing the support member 20 into left and right halves, a rigid member that does not have flexibility can be used as the support member 20. In addition, the left and right treatment mechanisms 60L and 60R can be swung in the same rotational direction (both left and right treatment mechanisms 60L and 60R rotate clockwise). The length of the support member 20 may also be extended from the rear to the side of the neck of the person being treated. This makes it possible to press on the neck of the person being treated from the left and right directions. More specifically, by attaching a neck-side air cell (not shown) that can press on the neck of the person being treated from the side to the extended portion of the support member 20, it becomes possible to press on the neck of the person being treated not only from the rear but also from the left and right directions. [Industrial applicability]
