Description

  The present invention relates to a chair-type massage machine for sitting on a seat and treating a user who is seated on a backrest, in particular, adjusting the tilt angle so that the seat can be tilted to treat the user. The present invention relates to a massage machine having a suitable posture.

  A chair-type massage machine that performs a massage operation while supporting the body of the user is usually a massaging ball as a treatment element provided on the backrest, and itching or hitting the user leaning on the backrest In addition to this, there is a device provided with a leg support portion (ottoman) with a built-in treatment mechanism so that predetermined treatment can be performed on the leg portion of the user. .

Such massage machines are often designed to easily adjust the inclination angle of the backrest and leg support using an actuator, depending on the type of treatment and the preference of the posture of the user in the treatment state. . However, such an actuator is not limited to use for adjustment, and is also used as one that causes movement of each part related to treatment. For example, as a massage machine using a leg support part, the leg support part is moved together with the leg by an actuator as a treatment operation in addition to stagnation by a treatment mechanism on the leg, and the positional relationship between the leg support part and the leg is changed. Thus, there has been proposed one that stretches leg muscles.
An example of a conventional massage machine that performs treatment by moving such a leg support is disclosed in Japanese Patent Application Laid-Open No. 2004-41383.

JP 2004-41383 A

  The conventional massage machine is configured as shown in the above-mentioned patent document, and has a mechanism in which the leg support part supporting the leg is tilted downward to stretch the leg, but the leg support part is moved to perform treatment. In particular, when a force is applied in the direction in which the legs are extended during treatment, the user moves along with the movement related to the treatment of the leg support portion while the user is seated on the seat, and the In some cases, the body cannot be held, and the body deviates from the position where it should originally be and cannot take an appropriate posture. During treatment, in order to suppress unnecessary movement of the leg, the leg's calf and thigh were sometimes pinched with an air cell, etc. from the side, but this was not sufficient to prevent body slippage. It was.

When the body is displaced in this way, the posture of receiving treatment by the user is not constant, and thus there is a problem that stable treatment cannot be performed on the user and an appropriate treatment effect cannot be obtained.
In addition, when aiming to improve swelling of the lower body with massage machine treatment, if the foot is at a position lower than the heart, the treatment effect related to swelling improvement, i.e., the effect of directing body moisture toward the upper body is insufficient. It is necessary to raise the position of the foot. However, if the position of the part that supports the foot is simply changed to increase the position of the foot, there is a problem that the posture becomes unreasonable for the user.

The present invention has been made to solve the above-mentioned problems, and the control unit adjusts the inclination angle of each part so as to obtain an optimal posture that is comfortable for the user while keeping the foot higher than the heart. Then, it aims at providing the massage machine which can perform treatment.

In addition, the massage machine according to the present invention includes, as necessary, the leg support portion including a foot support portion that is movable in the longitudinal direction of the leg and faces the sole, and the seat portion and the leg support portion. In accordance with the tilting of the backrest portion, the foot support portion is moved toward the side closer to the seat portion.

As described above, according to the present invention, there is no gap between the sole and the foot support portion, and the treatment can be performed in a stable state without the foot floating.

  As described above, according to the present invention, the ankle is held in a state where the angle formed between the tilted seat portion and the leg support portion is once close to 180 °, and then the angle formed between the seat portion and the leg support portion is set. When the ankle stretch is performed in a small state, the foot can be moved closer to the foot support when the foot is clamped, and the ankle can be easily clamped by the foot clamp. Stretching treatment to the ankle can be performed with the foot securely held on the foot support portion regardless. Also, in the state of treatment by moving the foot support part, the leg is bent further, so that the foot is moved away from the foot support part, and the movement of the foot support part corresponds to this foot position. Since the starting point can be set, the stroke of the stretch away from the seat of the foot support part can be secured, and the effect of the stretch can be enhanced.

  In addition, the massage machine according to the present invention includes a leg support part actuator that adjusts the inclination angle of the leg support part by tilting the leg support part with respect to the seat part as needed, and the user using the clamping means When the ankle part of the leg is clamped, the leg support part is tilted upward with respect to the seat part and the leg support part is tilted downward with respect to the seat part after clamping, at least by actuating the leg support part actuator. .

  As described above, according to the present invention, the foot support part actuator for tilting the leg support part with respect to the seat part is provided, and the leg support part is tilted independently of the seat part to form the seat part and the leg support part. By shifting to a state in which the angle is increased and the ankle is held and a state in which the angle formed between the seat and the leg support portion is decreased and the ankle is stretched, the ankle is clamped by the foot clamping means. Regardless of the state, the leg support portion can be made to have an appropriate inclination angle, and the effect of the difference in leg length can be made smaller, and the foot can be appropriately held on the foot support portion. In addition, when performing stretching treatment by moving the foot support part, the leg support part can be tilted as appropriate to adjust the orientation of the leg to a state suitable for treatment, reducing the burden on the leg and stretching the ankle. Can be executed smoothly without difficulty.

  In addition, the massage machine according to the present invention includes a range from the lower leg to the upper side of the ankle in the leg of the user, where necessary, the leg support part in the leg support part, except for the foot support part. Leg holding means that can be pressed by pressing a predetermined portion from the side is provided, and when the foot support part is separated from the other part of the leg support part, the leg holding means A predetermined portion above the ankle is sandwiched and held in the other portion.

  As described above, according to the present invention, when the leg support means is disposed in the leg support portion and the foot support portion is moved, the leg holding means holds the predetermined portion below the knee of the leg, and the upper side from the ankle is held. Since it can be held so that it does not move, the leg support part can be moved and the leg can be pulled, so that the leg part above the ankle can be prevented from stretching, and only the ankle stretch below the part held by the leg clamping means It can be executed in a concentrated manner, and the stretching treatment can be carried out more efficiently.

Hereinafter, a massage machine according to a first embodiment which is a reference of the present invention will be described with reference to FIGS. 1 to 7.
In each of the drawings, the massage machine 1 according to the present embodiment is a chair-like body that supports a seated user, and in detail, is a base that is placed on the floor and stably supports the entire chair. Part 11, a seat part 12 that supports the user's buttocks above the base part 11, a backrest part 13 that supports the user's back on the back side of the seat part 12, and both left and right sides of the seat part 12 The armrest 14 that supports the elbow and forearm of the user, the leg support 15 that supports the leg of the user on the front side of the seat 12, and the remote controller 30 that receives various operation inputs related to the massage operation. And a control unit 40 that controls the massage operation by the plurality of treatment mechanisms based on the contents of operation input, recorded information, and the like.

  The said base part 11 is mounted on the floor surface as a massage machine installation surface, and supports the said seat part 12, the backrest part 13, the armrest part 14, and the leg support part 15 which make each part of a chair. This base part 11 is a combination of a frame-like base frame 11a to which the seat part 12 and the backrest part 13 can be tilted, and an outer shell part 11b arranged to surround the base frame 11a. It is a configuration.

  The seat portion 12 is supported so that the inclination angle of the seat surface can be adjusted with respect to the base portion 11, and performs massage with a built-in treatment mechanism while supporting the buttocks and thighs of the user on the seat surface. As the treatment mechanism, a heel part air cell 71 and a thigh part air cell 72 that operate by supplying and discharging air are provided. An air pump 70 that operates these air cells by supplying and discharging air is disposed in a space below the seat portion 12.

  The seat 12 has a seat frame 12b that is located on the back side of the seat surface 12a and below each air cell and supports the entire seat. The rear part of the seat frame 12 b is pivotally supported on the upper part of the base frame 11 a of the base part 11. On the other hand, the front part of the seat frame 12b has a strength that does not deform with respect to the force applied relatively from the lower side to which the seat actuator 12d and the like is connected in the massage machine use state, and the function as a frame is a problem. The structure is complete. A seat actuator 12d that tilts the seat 12 is disposed between the front of the seat frame 12b and the lower portion of the base frame 11a of the base 11. In addition, left and right armrest portions 14 are integrally attached to the seat portion frame 12 b, and the armrest portions 14 can be tilted with respect to the base portion 1 together with the seat portion 12.

The seat actuator 12d is a known linear actuator having a mechanism for changing the length by expanding and contracting within a predetermined range as a whole by linearly moving the movable portion with respect to the fixed portion. The seat actuator 12d is located in a space formed below the seat 12 and inside the base 11, and is connected to the front portion of the seat frame 12b of the seat 12 so that one end can be tilted. On the other hand, the other end is connected to a predetermined position below the seat part below the base frame 11a of the base part 11 so as to be tiltable, and with the change in length due to expansion and contraction, the front part of the seat part frame 12b and In this configuration, the distance from the lower portion of the base frame 11 a is changed, and the seat 12 is tilted with respect to the base 11.
As in the case of a general linear actuator, the seat actuator 12d is provided with detection means for detecting the amount of movement of the movable part relative to the fixed part, that is, the amount of expansion / contraction of the entire actuator, for example, an encoder.

  The seat 12 is a mechanism that tilts around the shaft support portion at the rear portion of the seat frame 12b and changes the tilt angle of the seat surface by expansion and contraction accompanying the operation of the seat actuator 12d. Since the displacement associated with the tilt of the seat portion 12 corresponds to the displacement due to the expansion and contraction of the seat portion actuator 12d, the control portion 40 detects the amount of expansion and contraction of the seat portion actuator 12d. The tilting state can be grasped.

  In addition, the seat portion 12 is configured such that, in the initial state, the front portion is positioned slightly higher than the rear portion, and the seat surface is inclined at a predetermined angle, for example, about 5 ° with respect to the horizontal plane. If the seat 12 is tilted greatly, it is not easy for the user to sit down or stand up from the seat 12, so that the user sits on the seat 12 as much as a general chair. The inclination angle in the initial state of the seat 12 where such an action is performed is set so that the act of standing up and away from the seat 12 can be performed smoothly.

  In addition, the tilting range of the seat 12 is limited by the operating range of the seat actuator 12d, and a part of the base frame 11a of the base 11 at a predetermined tilting position, for example, a position where the lower limit of tilting is desired. The tilting range may be set on the basis of the movable range of the seat portion itself, such as abutment with the seat portion frame 12b as a stopper. In this case, avoiding a situation in which an excessive force is concentrated and applied to the seat actuator 12d from the seat 12 to be lowered by placing a heavy object on the seat 12 by mistake, etc., leading to damage to the actuator. You can also.

The backrest portion 13 has a surface shape that matches the shape of the human back and is arranged so that the inclination angle can be adjusted with respect to the base portion 11 and the seat portion 12, and a treatment mechanism for performing massage is provided therein. It is the composition provided.
Inside the backrest part 13 is a mechanical unit 50 in which a pair of left and right kneading balls 51 as a treatment element and a drive mechanism part 60 for operating the same are integrated, and the mechanical unit 50 can be moved in the vertical direction of the backrest part 13. A frame-like backrest frame 16 that supports each part of the backrest portion from the inside while supporting, and a back air cell 73 and a waist air cell 74 that are operated by supplying and discharging air by the air pump 70 are provided. . Of these, the mechanical unit 50, the back air cell 73, and the waist air cell 74 each constitute a treatment mechanism for performing massage.

  In addition, a pair of side wall portions provided with a treatment mechanism such as an air cell on the inner surface facing the user is provided on both the left and right sides of the backrest portion 13 so as to protrude from the upper arm of the user. You can also make it possible to massage from the side.

  The backrest frame 16 includes a pair of left and right guide frames 20 that allow the mechanical unit 50 to move in the vertical direction of the backrest 13 and restrain and support movement in other directions, and a pair of upper and lower guide frames 20 that form a frame with the guide frame 20.

  The backrest part frame 16 is pivotally supported by the lower part of the left and right guide frames 20 on the upper part of the base frame 11 a of the base part 11, and is supported to be tiltable with respect to the base part 11 as the entire backrest part frame 16. A backrest portion actuator 13d for tilting the backrest portion 13 is disposed between the horizontal frame 16a positioned below the tilt center of the backrest portion frame 16 and the seat frame front portion.

  The lower horizontal frame 16a of the backrest frame 16 is configured to apply a load applied to the backrest 13 from the user in a state where the massage machine is used based on the connection with the backrest actuator 13d. The force to push and contract this is transmitted to the backrest actuator 13d connected. For this reason, the horizontal frame 16a has sufficient strength not to be deformed with respect to the transmission of such force, and has a structure that can perform the function as a frame without any problem.

  It should be noted that in the backrest part frame 16, the pivotal support position of the base part 11 to the base frame 11a is the same as the pivotal support position of the seat part frame 12b in the base frame 11a, and the backrest part 13 is the base part. 11, the tilting center is the same as the tilting center of the seat 12, and is supported so as to be tiltable.

  Like the seat actuator 12d, the backrest actuator 13d is a known linear actuator having a mechanism that changes its length by expanding and contracting within a predetermined range as a whole by linearly moving the movable part relative to the fixed part. . The backrest actuator 13d is located in a space formed below the seat 12 and inside the base 11, and is connected to the horizontal frame 16a below the backrest frame 16 so that one end thereof can be tilted. On the other hand, the other end portion is connected to the front portion of the seat frame 12b of the seat portion 12 so as to be tiltable, and the distance between the lower portion of the backrest frame 16 and the front portion of the seat frame 12b is changed as the length changes due to expansion and contraction. As a result, the backrest 13 is tilted with respect to the seat 12, and as a result, the backrest 13 is tilted with respect to the base 11. As in the case of a general linear actuator, the backrest actuator 13d is provided with detection means such as an encoder that detects the amount of movement of the movable portion relative to the fixed portion, that is, the amount of expansion and contraction of the entire actuator.

  The backrest portion 13 tilts around the shaft support portion of the backrest portion frame 16 to the base frame 11a by the expansion and contraction accompanying the operation of the backrest portion actuator 13d, and changes the inclination angle of the entire backrest portion 13, that is, the reclining angle. It is a mechanism to make it. When the backrest 13 is tilted, the amount of expansion / contraction of the backrest actuator 13d is detected, so that the control unit 40 obtains the tilting state of the backrest 13 relative to the seat 12 and is obtained from this and the amount of expansion / contraction of the seat actuator 12d. By combining the inclination angle of the seat portion 12, the tilting state of the backrest portion 13 with respect to the base portion 11 can be grasped.

  The mechanical unit 50 includes a pair of left and right rubbing balls 51 as a treatment element that gives a user a stimulus such as rubbing and hitting, and a pair of left and right rubbing ball support arms 52 that respectively support the rubbing balls 51 in a protruding state.

In addition, based on the control of the control portion 40, a lift motor 57 that generates a drive force for lifting the mechanical unit, and a drive mechanism portion. And an advancing / retracting motor 58 for generating a driving force for tilting 60.

  The mechanical unit 50 is arranged in a state of being sandwiched between the guide frames 20 by supporting the side end portions of the base portion 54 on the pair of guide frames 20 so as to be able to run up and down, and the mechanical unit 50 as a whole along the guide frames 20. This configuration is movable. Then, based on the control by the control unit 40, the lifting motor 57 is actuated so that the base unit 54 travels along the guide frame 20, so that the entire mechanical unit 50 including the base unit 54 extends along the guide frame 20. This is a mechanism that moves up and down the backrest part 13 so that the position of the kneading balls 51 in the backrest part 13 (the treatment target site by the kneading balls) can be changed up and down.

  The mechanical unit 50 moves up and down the backrest 13 as described above under the control of the control unit 40 in accordance with the set massage content, and adjusts the vertical position of the kneading balls 51 and advances and retreats. The amount of protrusion of the kneading balls 51 toward the user is adjusted by the tilting of the kneading balls 51 and the drive mechanism 60 by the operation of the motor 58, and the kneading balls 51 are positioned at the massage target location. After the movement of the kneading balls 51 or in parallel with the movement of the kneading balls 51, the control unit 40 activates the motor for kneading and hitting the drive mechanism 60 in the mechanical unit 50 according to the type of massage. The movement corresponding to massage such as itchiness and hitting set in the kneading balls 51 is performed.

  The armrest portion 14 is located on both sides of the seat portion 12 and is integrally connected to the seat portion frame 12b. The armrest portion 14 is tilted together with the seat portion 12 as the seat portion 12 is tilted with respect to the base portion 11, and It is the structure formed so that a forearm part may be supported stably. The armrest portion 14 is provided with a forearm air cell (not shown) that operates by supplying and discharging air by the air pump 70, and is configured to massage the forearm portion of the user.

  The leg support portion 15 is positioned on the front side of the seat portion 12 and is disposed so as to be tiltable about the vicinity of the front end of the seat portion 12, and the tilt angle is adjusted by a leg support portion actuator 15d on the lower side of the seat portion. . Specifically, the leg support portion 15 is disposed so as to be tiltable with respect to the front portion of the seat frame 12b of the seat portion 12 and to be movable in the leg longitudinal direction on the surface side portion of the foundation portion 15a.

That is, the foot side air cells 79a, 79b, 79c, 79d also have a function as a foot holding means for holding the foot on the foot support portion 15c by holding the foot using the pressing force in the expanded state.

  With the foot side air cells 79a, 79b, 79c, and 79d holding the foot of the user and holding and fixing the foot on the foot support portion 15c, the seat portion actuator 12d is extended and the seat portion 12 faces upward. And the leg support 15 in the leg support 15 is moved in a direction away from the seat 12 with respect to the other parts of the leg support 15 such as the leg support 15b. . That is, the leg support 15 is used to perform stretch treatment on the ankle.

  When the foot support 15c is moved, the foot support 15c is moved if the leg air cells 75, 76, 77, 78 are inflated to sandwich the calf portion of the leg so as not to move above the ankle. At this time, it is preferable in that the stretch of the upper part from the ankle can be suppressed, only the ankle stretch can be concentrated, and the stretch can be executed efficiently.

  Thus, as a mechanism for moving the foot support portion 15c of the leg support portion 15 in the leg longitudinal direction with respect to the other portions of the leg support portion 15, the position change of the foot support portion 15c relative to the leg receiving portion 15b? The foot support section actuator 18 provided with a displacement detecting means for detecting the movement is used, and the operation of the foot support section actuator 18 is controlled by the control section 40. The foot support section actuator 18 is a known actuator such as a motor or a fluid pressure cylinder integrated with a known encoder or the like as the displacement detecting means, and will not be described in detail.

  The seat portion actuator 12d, the backrest portion actuator 13d, and the leg support portion actuator 15d operate independently of each other. For example, the reclining angle of the backrest portion 13 can be changed while the seat portion 12 is tilted. it can. It is preferable that the respective actuators are simultaneously operated to promptly shift the respective parts to the desired tilted state because the time until the start of treatment can be shortened.

  Further, when the seat portion 12 is tilted by the seat portion actuator 12d, if the backrest portion actuator 13d is maintained in the operation stop state, not only the seat portion 12 is tilted but also the backrest portion 13 is moved with respect to the base portion 11. It tilts and the reclining angle of the backrest 13 changes while the relative positional relationship with the seat 12 remains unchanged. Similarly, when the leg support portion actuator 15d is maintained in the operation stop state, the leg support portion 15 is tilted together with the seat portion 12 and the backrest portion 13 without changing the distance from the lower portion of the backrest portion frame 16, thereby The inclination angle with respect to the base portion 11 is changed, and the angle of the leg support portion 15 with respect to the horizontal plane is changed.

  The remote controller 30 includes a large number of switches and display units for receiving various operation inputs to the massage machine, is detachably installed on the stand 31 on the side of the massage machine 1, and transmits operation inputs related to massage to the control unit 40. Is. Note that the position of the stand 31 can be adjusted so that the position of the switch and the display unit of the remote controller 30 is the optimum position for the user.

  The control unit 40 adjusts the other movable parts of the treatment mechanism and the massage machine to a state corresponding to the user based on the detection result obtained by detecting the positions of the body parts of the user in advance. At the same time, control for performing appropriate treatment is performed on the treatment mechanism and other movable parts based on the remote control operation, the treatment contents recorded and set in advance, and the information on the detection result.

  The control unit 40 is a computer including a CPU, a memory, an input / output interface, and the like as its hardware configuration, and is a mechanism that causes the computer to operate as the control unit 40 by a program stored in the memory or the like. The computer constituting the control unit 40 may be a microcomputer in which a CPU, a memory, a ROM, and the like are integrally formed.

  The computer unit constituting the control unit 40 is disposed in a predetermined space inside the massage machine 1 such as directly under the seat 12 and is in a state where it can communicate with the remote controller 30, and various motors of the mechanical unit 50, The seat 12, the backrest 13, the actuators for tilting the leg support 15, and the air pump 70 are electrically connected to each other, and the position of each part of the body of the user is detected based on a preset position detection program. The operation of these drive mechanisms is controlled by the control signal output and by the control signal output based on the set massage data at the time of massage execution.

  In addition, the control unit 40 is also electrically connected to signal output means such as an encoder that outputs the displacement amount of the mechanical unit 50 and each actuator, and the state of the mechanical unit 50, the seat portion 12, the backrest portion 13, In addition, the operation control of the driving means such as the motor and the actuator is performed while grasping the state of the leg support 15 such as the inclination.

  In addition to this, the control unit 40 controls the mechanical unit 50 to detect the position of each part of the body of the user prior to the massage, as in a known massage machine, and the mechanical unit 50 is moved from the initial position of the backrest 13 to the guide rail 20. In the process of moving the kneading balls 51 along the user, a change in pressure with respect to the kneading balls 51 from the user leaning against the backrest 13 and a change in the inclination of the kneading balls 51 are sequentially acquired. Based on this information, the shoulder position, spine line, and waist position of the user can also be detected.

  Next, the operation of each part in the ankle stretch treatment of the user with the massage machine according to the present embodiment will be described. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest part 13, angle adjustment and length adjustment of the leg support part (including length adjustment of only the foot support part), etc. are completed. It is assumed that the control unit 40 is about to perform stretch treatment on the ankle while an operation state instruction such as a massage course is input by the user and various massage operations are performed.

  Then, before starting the operation control of each part related to the ankle stretch treatment, the control unit 40 determines that the inclination angle of the seat part 12 with respect to the horizontal plane is the minimum angle of the inclination angle adjustment range of the seat part related to the treatment, that is, on the seat part. If the angle is not the minimum inclination angle of 10 to 15 °, which can hold the user stably, the seat portion actuator 12d is operated, and the inclination angle of the seat portion 12 is Tilt until the minimum angle is reached.

  In executing the stretch treatment for the ankle, the control unit 40 first operates the leg support unit actuator 15d. That is, the leg support portion actuator 15d is actuated to be extended, and the leg support portion 15 is tilted upward by pushing the base portion 15a back side of the leg support portion 15 at one end of the leg support portion actuator 15d. The control unit 40 is configured to operate at a predetermined tilt angle corresponding to the treatment, for example, a predetermined tilt angle at which the angle formed between the seat 12 and the leg support 15 is in the range of 135 ° to 147 °, or the operation When the leg support 15 is tilted upward from a tilt angle at the start to a tilt angle advanced by a predetermined angle (for example, 10 °) in the leg support ascending direction, the operation of the leg support actuator 15d is stopped (see FIG. 5). . In this way, the leg support 15 is tilted upward to increase the angle formed between the seat 12 and the leg support 15, thereby reducing the bending of the leg at the knee, and the foot support 15 c and the foot. The positional relationship with the back is closer.

  As an operation for bringing the foot support portion 15c and the sole close to each other, in addition to the above-described operation, the control unit 40 can perform the foot support portion actuator 18 of the leg support portion 15 together with or in place of the tilt of the leg support portion 15. And the foot support 15c may be controlled to move slightly toward the side closer to the seat 12.

  As described above, when the positional relationship between the foot support portion 15c and the sole becomes closer to the state at the start of the operation set by the user, the control unit 40 causes the foot support portion 15c of the leg support portion 15 to move. Then, air is supplied to each foot side air cell located on both sides of the foot to inflate the foot side air cell. With the expansion of the foot side air cell, the foot is clamped more favorably from both sides by the air cell and is held integrally with the foot support portion 15c.

  The larger the angle formed between the seat 12 and the leg support 15, the closer the foot is to the foot support 15c. Therefore, the tilting range of the leg support 15 due to the operation of the leg support actuator 15d is increased. If the angle formed between the seat 12 and the leg support 15 is 180 ° or an angle close thereto, the foot can be brought as close as possible to the foot support 15c, regardless of the difference in leg length. The foot can be easily and reliably pinched by the side air cell.

  Such an operation is more suitable in the case of ankle stretch treatment, but in addition to the ankle stretch treatment, for example, when performing an operation related to treatment on the sole, such an operation is automatically performed in advance. Therefore, it is convenient to perform the sole treatment in which the adhesion between the sole and the foot support is improved.

  When holding the foot, if necessary, the control unit 40 causes the leg support unit 15 to supply air to each leg air cell located on both sides of the leg to expand the air cell. As the leg air cell expands, the calf portion of the leg is clamped from both sides by the air cell and is restrained by the leg receiving portion 15b.

  Subsequently, the control unit 40 operates and extends the seat actuator 12d, pushes up the front portion of the seat frame 12b of the seat 12 at one end of the seat actuator 12d, and tilts the seat 12 upward. When the seat portion 12 is tilted until a predetermined tilt angle corresponding to the treatment, for example, a predetermined angle within a range of 15 ° to 37 ° with respect to the horizontal plane, the control portion 40 operates the seat portion actuator 12d. To stop the tilting of the seat 12 (see FIG. 6).

And the control part 40 operates the foot support part actuator 18, and moves the foot support part 15c little by little to the side which leaves | separates from the seat part 12 with respect to the other part of the leg support part 15 (refer FIG. 7).
As a result, the foot held by the foot support portion 15c is separated from the leg above the ankle, and a load such as stretching exercise is applied to the ankle, and the muscles from the tendon of the ankle and the calf to the ankle Tension is obtained.

  When the ankle is tensioned by moving the foot support portion 15c, the seat portion 12 is inclined with a relatively large inclination angle so that the front portion is upward, so that the body is less likely to be displaced. Stable and efficient treatment can be performed by reliably maintaining the state of treatment at the treatment site.

  When the control unit 40 moves the foot support unit 15c by a predetermined distance, the operation of the foot support unit actuator 18 is stopped, the tension state of the ankle is maintained for a predetermined time, and the actuator is operated in the opposite direction to Release state. Then, if necessary, the process from when the ankle is in tension to when it is released is repeatedly executed. When one or more preset tensions are applied to the ankle, the treatment ends.

  When holding the foot, the control unit 40 inflates each leg air cell in the leg support unit 15 to hold and restrain the calf portion as necessary. The part or thigh may be clamped and restrained. Of course, even if such restraint is not performed, the seat portion 12 is inclined so that the front portion is upward at a relatively large inclination angle, so that the foot support portion 15c is moved away from other portions. However, it is difficult for the body to shift.

  As described above, the massage machine according to the present embodiment has the leg support portion 15 that is disposed to be tiltable on the front side and supports the leg with respect to the seat portion 12 that is tiltable on the base portion 11. The control unit 40 has the foot support portion 15c corresponding to the foot portion of the user, the control portion 40 holds the foot portion of the user to be held by the foot side air cell and is held by the foot support portion 15c. And the foot support portion 15c is moved away from the other portion to create a state of pulling the foot portion. As a result, the ankle is stretched, a load such as stretching exercise is applied to the ankle, and a tension state of the ankle tendon and muscles from the calf to the ankle is obtained. The treatment concerning the stretch can be executed, and an excellent treatment effect can be smoothly given to the user.

  In addition, when the seat portion actuator 12d is actuated, the tilt angle of the seat portion 12 can be adjusted, and when the foot support portion 15c is moved to pull the foot portion, the seat portion 12 is tilted and the leg is tilted to a sufficient tilt angle. By doing so, the center of gravity of the seated user is moved closer to the backrest portion 13, and the back and waist of the user are in a stable seating posture in which the backrest portion 13 is more closely attached, and the posture of the user is displaced. Treatment can be carried out without incurring the patient's body, and the body can be easily displaced from the original position with the movement of the user as in the case where the inclination angle of the seat 12 is smaller, and can be appropriately treated. It is possible to reliably perform treatment on a desired treatment target portion of the user, that is, the ankle, without falling into a state in which the posture is difficult to take.

(Second embodiment the present invention)
A massage machine according to a second embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, the difference is that the control unit 40 tilts the seat 12 and the leg support 15 to raise the legs, and tilts the backrest 13 so as to tilt the legs. To obtain a treatment posture that is higher than the position of the heart, and executes a predetermined treatment for the lower body portion of the user.
In addition to the control related to the tilt adjustment of each part, the backrest part is tilted together with the tilting of the seat part to make the user a predetermined treatment posture in which the foot is higher than the heart. This is the same as the case of the embodiment, and detailed description is omitted.

  When aiming to improve swelling of the lower body with massage machine treatment, if the foot is at a lower position than the heart, the treatment effect related to swelling improvement, that is, the effect of directing body moisture toward the upper body is insufficient Therefore, it is necessary to raise the position of the foot. However, simply trying to raise the position of the foot by simply changing the position of the part that supports the foot results in a posture that is unreasonable for the user. In this embodiment, while the foot is in a state of being higher than the heart, Then, the control unit 40 adjusts the inclination angle of each part so as to obtain an optimal posture that is comfortable for the user, and then performs the treatment.

  Specifically, the control unit 40 operates the seat portion actuator 12d to increase the inclination angle of the seat portion 12, and operates the leg support portion actuator 15d to tilt the leg support portion 15 to a position higher than the seat portion 12. (See FIG. 8), the user's leg is raised high. Further, the control unit 40 operates the backrest actuator 13d to tilt the backrest portion 13 backward to increase the angle formed by the seat portion 12 and the backrest portion 13 and relatively lower the position of the upper body of the user. Thus, the foot is positioned higher than the heart.

In this case, the leg falls to the backrest side with the inclination of the seat portion 12, and as the leg is displaced, the sole of the foot is separated from the foot support portion 15c, and the foot is in an unstable state. It is easy to become. Therefore, the control unit 40 operates the foot support unit actuator 18 to adjust the position of the foot support unit 15c in accordance with the tilting of the seat unit 12 and the leg support unit 15, and the sole and the foot support unit 15c are separated from each other. (See FIG. 10).
Thus, after the legs are raised by tilting each part and the legs are raised above the heart, the control unit 40 shifts to a treatment state, such as performing a massage along a normal massage course.

  Next, the operation | movement of each part for the treatment with the massage machine which concerns on this embodiment is demonstrated. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest 13 and the like are completed, and an operation state instruction such as a massage course is input by the user, and various massage operations are executed. In particular, it is assumed that the control unit 40 is about to perform treatment for the purpose of improving swelling of the lower body.

  First, the control unit 40 operates the seat actuator 12d to extend or contract, and moves the seat frame 12b front part of the seat 12 up or down at one end of the seat actuator 12d to move the seat 12 up and down. Tilt is performed until the tilt angle is set in advance corresponding to the treatment, for example, a predetermined angle within a range of 33 ° to 37 ° with respect to the horizontal plane.

  Further, with respect to the backrest 13, the control unit 40 operates the backrest actuator 13 d to extend or contract, and the backrest actuator 13 d moves the lower portion of the backrest 13 forward or backward relative to the front of the seat 12. Thus, the backrest 13 is tilted until a predetermined tilt angle, for example, an angle between the seat 12 and the backrest 13 is within a range of 121 ° to 128 °. In addition, even if the inclination angle of the seat portion 12 and the backrest portion 13 with respect to the base portion 11 is adjusted, when the angle formed between the backrest portion 13 and the seat portion 12 can be expected to be unchanged before and after the adjustment, When the control unit 40 does not operate the backrest actuator 13d and stops only the seat actuator 12d, the backrest 13 is interlocked with the tilting of the seat 12 via the stopped backrest actuator 13d. The part 13 can be tilted while maintaining the relative positional relationship with the seat part 12 to reach a desired angle.

  Further, for the leg support 15, the control unit 40 operates the leg support actuator 15 d to extend or contract, and the leg support actuator 15 d moves the leg support 15 forward or backward relative to the lower part of the backrest 13. Thus, the leg support 15 is tilted until a predetermined tilt angle, for example, a predetermined tilt angle in which the angle between the seat and the leg support is within a range of 143 ° to 180 °.

Even if the inclination angle of the backrest part 13 and the leg support part 15 with respect to the base part 11 is adjusted, the lower part of the backrest frame 16 and the leg support part 15 to which the respective end parts of the leg support part actuator 15d are connected respectively. If the controller 40 is expected to remain unchanged before and after the adjustment, the controller 40 stops the leg support actuator 15d without operating the leg support actuator 15d, and operates only the backrest actuator 13d. The leg support 15 is interlocked with the tilt of the backrest 13 via 15d, and the leg support 15 tilts while maintaining a distance from the lower portion of the backrest frame 16 so that a desired angle can be reached.
A state where the foot of the user is positioned higher than the heart is obtained by the tilting of the seat portion 12 and the leg support portion 15 and the backrest portion 13 (see FIG. 9).

  On the other hand, when the leg is in a raised state, a gap is generated between the sole and the foot support portion 15c as the leg is displaced downward, so that the foot is lifted. At the same time or at different times, the control unit 40 operates the foot support unit actuator 18 of the leg support unit 15 to move the foot support unit 15c closer to the seat 12 with respect to the other part of the leg support unit 15. Then, the position of the foot support 15c is adjusted so as to contact the sole of the user (see FIG. 10). As a result, there is no gap between the sole and the foot support portion 15c, and the treatment can be performed in a stable state without the foot floating.

  After the inclination angle of each part is adjusted in this way and the foot of the user is positioned higher than the heart, the control unit 40 performs the massage operation by each treatment mechanism corresponding to the massage course selected by the user. To improve the swelling. Alternatively, after the foot is at a higher position than the heart, the control unit 40 stops the operation of each actuator for a predetermined time, holds the posture in which the user's foot is raised for a predetermined time, and naturally moves from the leg toward the heart. Operate each mechanism in response to swelling improvement, such as promoting blood flow and then expanding and contracting the leg air cell and foot side air cell to act as a pump that directs blood flow toward the heart. Carry out special treatment.

  As described above, the massage machine according to the present embodiment tilts the seat 12 when the foot position is raised, and increases the inclination angle with respect to the horizontal plane, thereby supporting the leg even when the foot is in a high position. It does not become an unreasonable posture and can effectively improve swelling.

(Third embodiment for reference of the present invention)
A massage machine according to a third embodiment which is a reference of the present invention will be described with reference to FIGS.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, as a different point, a foot air cell 79e as a treatment mechanism for stimulating the sole of the user is disposed on the foot support 15c facing the sole of the user at the leg support 15 as a different point. The control unit 40 is configured to perform a treatment in which a stimulus is applied from the sole air cell 79e of the foot support unit 15c to the sole of the user in a state where the seat 12 and the leg support unit 15 are tilted to raise the foot. It is something to execute.
The foot support portion 15c is provided with a treatment mechanism for the sole and is the same as in the case of the first embodiment, except for performing control related to treatment to the sole using the treatment mechanism. Detailed description is omitted.

As in the first embodiment, the foot support portion 15c includes foot side air cells 79a, 79b, 79c, and 79d, and a portion that faces the sole of the user while supporting the foot of the user. Further, a sole air cell 79e as a treatment mechanism that expands and contracts by supplying and discharging air by the air pump 70 is provided for each of the left and right feet. These sole air cells 79e are built in a paired arrangement on the left and right so that the foot sole portions of the left and right feet can be pressed in the expanded state to perform massage by pressing stimulation.
The foot support portion 15c is provided with other treatment mechanisms such as a roller for pressing the sole while rotating and / or moving in the longitudinal direction of the foot instead of the foot air cell 79e or together with the foot air cell. It doesn't matter if you do.

  Next, treatment for applying stimulation to the sole of the massage machine according to the present embodiment will be described. First, prior to operating the sole air cell 79e as a treatment mechanism, the control unit 40 appropriately bent the legs of the user by adjusting the inclination angle of the seat part 12 and the inclination angle of the leg support part 15. State.

  Paying attention to the positional relationship between the foot support 15c and the sole, the state in which the inclination angle of the seat 12 and the leg support 15 is set so that the leg is straightened is the closest to the sole and the foot support 15c. On the contrary, when the degree of bending the leg is increased, the sole is separated from the foot support portion 15c accordingly.

  That is, the tilt of the seat 12 increases the upward tilt angle of the seat 12 with respect to the horizontal plane and raises the leg, while the angle between the seat 12 and the leg support 15 decreases to reduce the bending of the leg at the knee. If it is in a large state, the lower part of the leg from the knee is shifted closer to the knee on the leg support part 15, and the sole is separated from the foot support part 15c, so that the treatment strength can be reduced (see FIG. 11). In addition, the tilt of the seat 12 reduces the upward tilt angle of the seat with respect to the horizontal plane, thereby reducing the rise of the leg, while increasing the angle formed by the seat 12 and the leg support 15 at the knee of the leg. If the bend is in a small state, the foot approaches the foot support portion 15c on the leg support portion 15, and the treatment strength to the sole can be further increased (see FIG. 12).

The control unit 40 is operated by the user so that when the foot air cell 79e is operated by tilting the seat 12 while appropriately adjusting the tilt angle, the pressure stimulation to the sole is appropriate. Based on this, the positional relationship between the foot support 15c and the sole is adjusted.
When the sole air cell 79e is operated after such adjustment, a stimulus having an appropriate strength suitable for the user is applied to the sole from the foot support portion 15c side through the adjustment.

  Even during treatment, when the intensity of stimulation is changed as necessary, the control unit 40 operates and extends the seat actuator 12d based on the user's operation, and tilts the seat 12 by tilting upward. Increase the angle to relieve the stimulus by moving the sole away from the foot support 15c, or conversely, actuate the seat actuator 12d to contract and tilt the seat 12 downward to reduce the tilt angle. The stimulation can be strengthened by bringing the soles close to the foot support 15c (see FIG. 13).

  In the state where the legs are supported by the leg support part 15, the longer the leg, the closer the foot is to the foot support part 15c. Although there is a possibility that the stimulation to the sole becomes excessive, as in the present embodiment, the positional relationship between the foot support 15c and the sole is adjusted by changing the inclination angle of the seat 12 before the treatment. By being able to do so, treatment can be performed with an appropriate stimulus intensity regardless of the length of the legs.

  The leg support 15 is connected to the seat 12 and the backrest 13 via an actuator, and interlocks with the tilting of the seat 12 when each actuator is stopped. That is, when the seat portion 12 is tilted upward, the leg support portion 15 tilts together with the seat portion 12 with respect to the base portion 11, while the seat portion 12 and the leg support portion 15 are tilted with respect to the seat portion 12. The leg is tilted relatively so as to reduce the angle formed, and the bending of the leg is increased. On the other hand, when the seat portion 12 is tilted downward, the leg support portion 15 tilts relative to the seat portion 12 so as to increase the angle between the seat portion 12 and the leg support portion 15, thereby bending the leg. Make it smaller. If the bend of the leg is large, the foot tends to move away from the foot support portion 15c, and conversely, if the bend of the leg is small, the foot tends to approach the foot support portion 15c. Even in conjunction with the actuator alone, the seat 12 is tilted to further promote the movement of the foot due to the tilt of the seat 12. Therefore, the leg support portion actuator 15 does not necessarily have to be operated in accordance with the tilting of the seat portion 12.

(Fourth embodiment for reference of the present invention)
A massage machine according to a fourth embodiment which is a reference of the present invention will be described with reference to FIGS. 14 and 15.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, the difference is that the control unit 40 tilts them so as to reduce the angle formed between the seat 12 and the backrest 13 to bring the user into an appropriate posture, and then the seat 12 and the backrest 13 are tilted in opposite directions, and the mechanical unit 50 is operated so that the kneading balls 51 are in a protruding state, and stretch treatment is performed to extend the waist of the user.
The points other than the tilting of the seat 12 and the backrest 13 for the purpose of stretching the waist and the control related to the operation of the mechanical unit 50 are the same as in the case of the first embodiment. Description is omitted.

  Assuming that the waist air cell 74 of the backrest 13 is greatly inflated and the waist is strongly pushed up from below while the backrest 13 is largely tilted in the massage machine, the waist pushed from below extends and the effect of stretching on the waist Can be expected. However, the pressure by the actual air cell is dispersed and the amount of push-up is insufficient, and the backrest part 13 is greatly tilted, so the treated person is close to a sleeping posture and the body pressure is dispersed, The user easily deviates with the force received by the treatment and the user's own movement, and the body is difficult to hold on the massage machine such as the waist is floating. In this embodiment, the control unit 40 tilts the seat 12 and the backrest 13 so that the waist can be appropriately treated, and after positioning, the posture of the user is maintained while maintaining the posture of the user. Perform treatment.

  Specifically, the control unit 40 operates the seat portion actuator 12d to increase the inclination angle of the seat portion 12, and also operates the backrest portion actuator 13d, so that the angle between the backrest portion 13 and the backrest portion 13 is increased. It is caused to tilt in the direction of decreasing, and the lumbar part of the user falls into a recessed part formed between the seat part 12 and the backrest part 13 (see FIG. 14).

Next, the control unit 40 operates the seat portion actuator 12d to reduce the inclination angle of the seat portion 12 and also operates the backrest portion actuator 13d to tilt the backrest portion 13 backward so that the seat portion 12 and the backrest portion 13 Is increased (see FIG. 15). However, the seat portion 12 is inclined upward with respect to the horizontal plane, and the state where the knee of the user's legs is raised higher than the waist is maintained, so that the posture of the user can be maintained.
On the other hand, by increasing the angle formed between the seat 12 and the backrest 13 and simultaneously operating the mechanical unit 50 to bring the kneading balls 51 into a protruding state, it is possible to push up the waist and stretch the waist. It has become.

  Next, the operation of each part in the waist stretch treatment with the massage machine according to the present embodiment will be described. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest 13 and the like are completed, and an operation state instruction such as a massage course is input by the user, and various massage operations are executed. In particular, it is assumed that the control unit 40 is about to perform stretch treatment on the waist.

  And before starting the operation control of each part related to treatment, the control unit 40 makes the inclination angle of the seat part 12 with respect to the horizontal plane stable on the minimum angle of the inclination angle adjustment range of the seat part related to treatment, that is, on the seat part. If the angle is not 10 to 15 degrees, which is the minimum inclination angle that can hold the user, the seat portion actuator 12d is operated, and the inclination angle of the seat portion 12 is set to the minimum angle. Tilt until. The seat position where the inclination angle of the seat section 12 is the minimum angle is the initial position related to the treatment of the seat section 12. In addition, when the mechanical unit 50 does not exist in the vicinity of the waist of the user, the control unit 40 operates the lifting motor 57 of the mechanical unit 50 so that the mechanical unit 50 is treated against the backrest 13. Move the person near the waist.

  First, the control unit 40 operates the seat portion actuator 12d to be extended with respect to the seat portion 12 in the initial position in treatment, and pushes the front portion of the seat portion frame 12b of the seat portion 12 at one end portion of the seat portion actuator 12d. Then, the seat 12 is tilted upward. The control unit 40 tilts the seat 12 until it reaches a preset tilt angle for adjusting the posture of the user, for example, a predetermined angle within a range of 33 to 37 ° with respect to the horizontal plane.

  At the same time, the control unit 40 operates the back portion actuator 13d to extend or contract, and the back portion actuator 13d moves the lower portion of the back portion 13 relative to the front portion of the seat portion 12 forward or backward to move the back portion. 13 is tilted until a tilt angle preset for posture adjustment, for example, a predetermined tilt angle in which the angle between the seat portion 12 and the backrest portion 13 falls within a range of 121 to 128 °.

  In this way, the inclination angle of the seat portion 12 is increased, and the angle formed by the seat portion 12 and the backrest portion 13 is made relatively small, so that the body of the user, particularly the waist, is placed between the seat portion 12 and the backrest portion 13. It becomes easy to slip, and the waist position which is a treatment object part of a user is correctly positioned (see FIG. 14).

  After the waist position is determined, the controller 40 operates the seat actuator 12d to contract, lowers the front part of the seat frame 12b of the seat 12 connected to one end of the seat actuator 12d, and faces the seat 12 downward. Tilt to. The control unit 40 tilts the seat 12 until it reaches a preset tilt angle corresponding to the treatment, for example, a predetermined angle within a range of 10 to 15 ° with respect to the horizontal plane.

  At the same time, the control unit 40 operates and contracts the backrest actuator 13d, and closes the lower portion of the backrest portion 13 to the front portion of the seat portion 12 with the backrest actuator 13d, so that the control portion 40 tilts backward to the backrest portion 13. The tilting component is applied, and the tilting angle of the backrest portion to be tilted in the direction that occurs forward in conjunction with the tilting of the seat portion 12 is maintained or tilted by a predetermined angle in the direction of actually tilting backward.

  At this time, the leg support 15 is linked with the movement of the backrest 13 and the seat 12 via each actuator, and if the leg support actuator 15d is not operated, the leg support 15 moves with the movement of the seat 12 and the backrest 13. Since the support portion 15 tilts upward and the angle formed between the seat portion 12 and the leg support portion 15 is excessively increased to weaken the waist stretching effect, the leg support portion actuator 15d is operated to operate the leg support portion. It is desirable to apply a downward tilting component to 15 so that the angle formed by the seat 12 and the leg support 15 does not change much.

  As the angle between the seat 12 and the backrest 13 is increased and the body of the user is stretched, the control unit 40 operates the advance / retreat motor 58 of the mechanical unit 50 to The drive mechanism 60 is tilted, the kneading balls 51 are protruded toward the user so as to press against the waist of the user leaning against the backrest 13, and the kneading balls 51 are pushed up and lifted up. The waist is stretched (see FIG. 15).

  In this way, with the waist correctly positioned, push the waist strongly with a kneading ball, push the waist up and stretch, and perform stretch treatment to ensure the treatment effect on the correct treatment target waist Can do.

  In the massage machine according to the above-described embodiment, the control unit 40 particularly controls the leg support unit actuator 15d that tilts the leg support unit 15 when the seat unit 12 is tilted upward in the stretch treatment. In addition to this, the control unit 40 operates and extends the leg support actuator 15d and tilts the leg support 15 upward at the same time as the upward tilt of the seat 12 from the initial position. The angle between the seat portion 12 and the leg support portion 15 can be increased to obtain a state in which the bend at the knee of the leg is small. In this case, since the leg is not restrained due to the small bending of the leg, the user's waist can be more easily slid between the seat 12 and the backrest 13, and the waist position of the user can be positioned smoothly. It becomes possible.

  Further, in the massage machine according to the above-described embodiment, it is configured to not operate other mechanisms except for the tilting of the seat portion and the backrest portion and the operation of the mechanical unit in relation to the stretching treatment, The air cell capable of sandwiching the seat portion 12 is disposed on both sides of the seat portion 12, and the seat portion 12 and the backrest portion 13 are tilted to once reduce the angle formed by the seat portion 12 and the backrest portion 13. The air cell may be expanded and the leg thighs may be clamped before the angle formed by the backrest 13 is increased. In this case, when the thigh is sandwiched between the air cells on both sides of the seat 12 and the seat is tilted, the thigh is sandwiched between the air cells and pressed into the seat. 12, the position of the positioned waist is surely held, and the waist can be stretched by accurately pressing the waist with the kneading balls, so that the stretch effect of the waist can be further enhanced.

  Similarly, an air cell that presses the shoulder portion of the user can be arranged on both sides of the backrest portion 13, and the air cell can be inflated to press and hold the shoulder portion against the backrest portion. When the part is tilted, the upper body becomes difficult to move with respect to the backrest part 13 by the shoulder being pressed by the air cell, and the positioned waist part can be reliably held at that position.

(Fifth embodiment for reference of the present invention)
A massage machine according to a fifth embodiment which is a reference of the present invention will be described with reference to FIGS.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, as a different point, the control unit 40 inflates the air cells 14a and 14b of the armrest part 14 in a state where the seat 12 is tilted upward and the user is in an appropriate posture, and the forearm is expanded. The body is held, and then the backrest 13 is tilted backward and tilted, and the body of the user is also tilted backward to execute stretch treatment for extending the arm of the user.
The points other than the control relating to the tilting of the seat 12 and the backrest 13 and the operation of the air cells 14a and 14b of the armrest 14 for the purpose of stretching the arm are as in the case of the first embodiment. It is the same, and detailed description is omitted.

  When the backrest 13 is tilted backward with respect to the armrest 14 integrated with the seat 12, that is, when the reclining angle is increased, the body of the user leaning against the backrest 13 will also move backward. If neither is performed, the arm placed on the armrest portion 14 also tends to shift backward as the body moves. On the other hand, if the air cells 14a and 14b provided in the armrest part 14 are expanded and the forearm part is pressed and held on the armrest part 14 before the backrest part 13 is tilted backward, the backrest part is obtained. When the arm 13 is tilted, the forearm portion held on the armrest portion 14 tries to maintain the position of the upper arm portion of the arm that moves backward with the body, so that the arm moves relatively forward. The arm is stretched and the arm can be given a stretch effect by stretching.

  Next, the operation of each part in the arm stretch treatment with the massage machine according to the present embodiment will be described. As a premise, the main power of the massage machine 1 is turned on with the user sitting on the massage machine 1 and the back resting on the backrest part 13 and the arm part placed on the armrest part 14. The preparation operation before the start of massage, such as detection of the weight and body shape of the user, adjustment of the reclining angle of the backrest portion 13 and the like are completed, and further, an operation state instruction such as a massage course is input by the user In the course of executing various massage operations, it is assumed that the control unit 40 is about to perform arm stretching treatment.

  First, the controller 40 operates the seat actuator 12d to extend or contract the seat 12, and moves the front of the seat frame 12b of the seat 12 up or down at one end of the seat actuator 12d. The seat 12 is tilted until it reaches a preset tilt angle corresponding to the treatment, for example, a predetermined angle within a range of 15 to 37 ° with respect to the horizontal plane.

  Further, with respect to the backrest portion 13, the control unit 40 operates the backrest portion actuator 13 d to extend or contract, and the backrest portion actuator 13 d moves the lower portion of the backrest portion 13 forward or backward relative to the front portion of the seat portion 12. The backrest portion 13 is tilted until a predetermined inclination angle, for example, an angle formed between the seat portion 12 and the backrest portion 13 is within a range of 115 to 128 °.

  As the seat portion 12 is tilted, the armrest portion 14 on which the forearm portion is placed is also tilted, and the forearm portion is positioned in front of the body in an appropriate direction. Air cells 14a and 14b for the forearm in the armrest 14 are inflated against the forearm to press the forearm and hold the forearm on the armrest 14 (see FIG. 16).

  After the forearm is held on the armrest 14 by the air cells 14a and 14b, the control unit 40 operates the backrest actuator 13d to contract, and the backrest actuator 13d pulls the lower part of the backrest 13 to the front of the seat 12. By bringing them together, the backrest 13 is tilted backward to be brought down (see FIG. 17). Prior to tilting the backrest 13, the seat 12 is tilted with a relatively large tilt angle so that the front is up, so that the body is not easily displaced and stable and efficient. Can be treated.

Due to the further tilting of the backrest part 13, the body of the user will fall further back and the arm part tends to shift backward together with the body, but the forearm part is held by the armrest part 14, The arm is pulled relatively forward. As a result, a load such as stretching exercise is applied to the arm, each part of the arm is stretched, and an effect equivalent to performing the arm stretching exercise is produced.
The inclination angle of the backrest part 13 at this time is appropriately adjusted according to the treatment intensity of the stretch to be given because the treatment intensity of the stretch increases as the angle between the seat part 12 and the backrest part 13 increases.

  In addition to tilting the seat portion 12 and the armrest portion 14 to an appropriate inclination angle, the backrest portion 13 is tilted rearward to shift the position of the body of the user to be held by the armrest portion 14. The forearm portion is positioned above the base side of the arm, and the weight of the arm itself becomes a load, so that the arm can be extended more efficiently.

  In the massage machine according to the above-described embodiment, the air cells 14a and 14b disposed on the armrest portion 14 are inflated to hold the forearm portion, and the backrest portion 13 is tilted and tilted to extend the arm of the user. In addition to this, as shown in FIG. 18, a plurality of air cells are arranged in the longitudinal direction of the arm of the armrest portion 14, and a set of air cells 14c and 14d on the front side (fingertip side) The control unit 40 controls the expansion and contraction of the rear (elbow-side) air cells 14e and 14f separately, and in combination with the control of the inclination angle of the seat part and the backrest part, the treatment variation for the arm is increased. It can also be configured.

  In this case, too, either the front air cell 14c, 14d group or the rear air cell 14e, 14f group or both are inflated by air supply and the arm is pressed in the same manner as described above. When the part 13 is tilted rearward and tilted, the portion pressed by the air cell of the arm is held on the armrest part 14, whereas the rear part of the arm moves the body due to the tilt of the backrest part 13. Accordingly, the arm is pulled relatively forward by attempting to move backward. In this way, each part of the arm is stretched, and an effect equivalent to performing the arm stretching exercise is produced.

  Further, the set of the air cells 14c and 14d on the front side is expanded by supplying air to press the arm, and the backrest portion 13 is tilted backward to be tilted so that the same arm is relatively pulled forward. On the other hand, the air cell 14e and 14f on the rear side may be repeatedly expanded and contracted by air supply and exhaust. Thereby, the pressure stimulation by the air cells 14e and 14f is repeatedly applied to the arm while applying a load such as stretching exercise to the arm, and the treatment effect of the stretch can be further enhanced by the combined use of such arm massage.

  In addition, the arm is held by the front air cells 14c and 14d of the armrest portion 14, and the arm is supported in an upward position, and then the expansion and contraction by the supply and exhaust of the air cells 14e and 14f on the rear side are repeated to By intermittently pressing, the flow of lymph toward the arm root like a pump is promoted, and the effect as a lymph massage is enhanced.

(Sixth embodiment for reference of the present invention)
A massage machine according to a sixth embodiment which is a reference of the present invention will be described with reference to FIGS.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, the difference is that the control unit 40 inflates the leg air cell of the leg support unit 15 in a state where the seat 12 is tilted upward and the user is in an appropriate posture. The leg support 15 is then tilted upward, and the leg support 15b is moved away from the seat 12 to perform stretch treatment to extend the back of the user's legs. It is.
The points other than the control related to the tilting of the seat 12 and the leg support 15 and the movement of the leg support 15b for the purpose of stretching the leg back are the same as in the case of the first embodiment. Detailed description will be omitted.

  With the leg air cells 75, 76, 77, 78 holding the legs of the user and holding and fixing the legs on the leg support portion 15, the leg support portion actuator 15 d is extended to extend the leg support portion 15. When the leg receiving portion 15b of the leg support portion 15 is moved in the direction away from the seat portion 12 with respect to the base portion 15a, a stretch effect by stretching can be imparted to the back side portion of the leg. That is, the leg support 15 is used to perform stretch treatment on the leg back.

  In tilting the leg support portion 15, not only the leg is restrained on the leg support portion 15, but also the position of the leg receiving portion 15 b holding the leg is moved appropriately in a direction away from the seat portion 12, By adjusting the degree of bending, the knee lift can be reliably suppressed without excessive force applied to the knee, and the leg stretching effect can be further enhanced.

  Thus, as a mechanism for moving the leg receiving portion 15b of the leg supporting portion 15 in the leg longitudinal direction with respect to the base portion 15a, a leg provided with a displacement detecting means for detecting a positional change of the leg receiving portion 15b with respect to the base portion 15a. The receiving portion actuator 19 is used, and the operation of the leg receiving portion actuator 19 is controlled by the control portion 40. The leg receiving portion actuator 19 is a known actuator such as a motor or a hydraulic cylinder in which a known encoder or the like as the displacement detecting means is integrated, and detailed description thereof is omitted.

  Next, operation | movement of each part in the stretch treatment of the leg back part with the massage machine which concerns on this embodiment is demonstrated. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest 13 and the like are completed, and an operation state instruction such as a massage course is input by the user, and various massage operations are executed. In particular, it is assumed that the control unit 40 is about to perform stretch treatment on the leg back.

  Then, before starting the operation control of each part related to the stretch treatment, the control unit 40 operates and contracts the leg support unit actuator 15d when the leg support unit 15 is not in the lowest position as its initial position. The leg support 15 is tilted to the initial position (see FIG. 19). In addition, when the leg receiving portion 15b of the leg support portion 15 is not closest to the seat portion 12, the leg receiving portion actuator 19 is actuated to bring the leg receiving portion 15b closer to the seat portion 12. Move to.

  First, the controller 40 operates the seat actuator 12d to extend or contract the seat 12, and moves the front of the seat frame 12b of the seat 12 up or down at one end of the seat actuator 12d. The seat 12 is tilted until it reaches a preset tilt angle corresponding to the treatment, for example, a predetermined angle within a range of 15 to 37 ° with respect to the horizontal plane (see FIG. 19).

  Thereafter, the control unit 40 causes the leg support unit 15 to supply air to each leg air cell located on both sides of the leg to inflate the air cell. As the leg air cell expands, the calf portion of the leg is clamped from both sides by the air cell and is restrained by the leg receiving portion 15b.

  In a state where the leg air cell is sufficiently expanded and the calf portion is sandwiched and restrained, the control unit 40 extends the leg support unit actuator 15d with respect to the leg support unit 15, and the leg support unit actuator 15d has one end on the leg support unit 15d. The support portion 15 is pushed to tilt the leg support portion 15 upward.

After the leg support unit 15d starts to tilt the leg support unit 15d and the end of the leg support unit 15 is separated from the floor to some extent, the control unit 40 operates the leg receiving unit actuator 19 of the leg support unit 15 to operate the leg support unit 15d. The leg receiving part 15b of the support part 15 is moved little by little to the leg tip side which is the side away from the seat part 12 with respect to the base part 15a (see FIG. 21).
In this way, by moving the leg receiving portion 15b to the distal end side of the leg, the leg support 15 is tilted upward while the leg is attached to the seat 12 or the leg support 15 and the back of the leg is properly stretched. The state where it can continue is obtained.

  The movement of the leg receiving portion 15b toward the leg tip side is executed while grasping the movement displacement of the leg receiving portion 15b, and corresponding to the tilted state of the leg supporting portion 15, the foot and leg support of the user The amount of movement is adjusted so that the end of the portion 15 does not contact the floor surface.

  In a state where the leg support portion actuator 15d is extended to tilt the leg support portion 15 upward and lift the portion below the knee of the user's leg, the leg that is upward due to the tilt of the seat portion 12 On the other hand, the leg air cell restrains the calf portion of the leg and moves the leg receiving part 15b to the leg tip side to maintain the leg in contact with the seat part and the leg support part. The body is pulled forward while taking an appropriate posture, and a load such as stretching exercise is applied to the leg, and the part from the back of the leg, especially from the back of the thigh to the back of the knee is stretched. .

  Thereafter, when the tilt of the leg support 15 progresses and the angle formed between the leg support 15 and the seat 12 reaches a predetermined angle close to the limit of the movable range of the legs of the user, the control is performed. The unit 40 sends an operation stop control command to the leg support unit actuator 15d and the leg air cell supply / discharge control mechanism. Thereafter, the leg support portion actuator 15d is stopped and the tilting of the leg support portion 15 is stopped.

  In this way, the tilting of the leg support 15 is stopped without exceeding the stretch treatment strength selected and set in advance, and stretch with an appropriate treatment strength becomes possible. Before the leg support 15 is tilted and the leg support 15b is moved so that the back of the leg is in the extended state, the seat 12 is tilted so that the front is upward at an appropriate tilt angle. By doing so, the body is not easily displaced, and the state where the stretch treatment is performed on the back of the legs is reliably maintained, so that stable and efficient treatment can be performed.

  The control unit 40 stops the leg support unit actuator 15d, and contracts the leg air cell by discharging air to release the leg from the sandwiched state, and returns the leg to a state in which the leg can be moved freely. Thereafter, the control unit 40 also stops the operation of the leg receiving unit actuator 19 and stops the movement of the leg receiving unit 15b, thereby completing a series of stretch treatments.

  As described above, when the leg support unit 15 is tilted upward as a stretch treatment for the leg back portion, the massage machine according to the present embodiment holds the leg with the leg air cell in advance and puts it on the leg receiving portion 15b. Since the leg receiving portion 15b is moved little by little in a direction away from the seat portion 12 in accordance with the progress of tilting, the leg support portion is lifted without being lifted from the leg support portion 15 or the seat portion 12. 15 is tilted upwards and the legs are stretched, and a state in which the muscles of the soles of the legs are efficiently stretched without imposing a burden on the knees is obtained. It can be executed appropriately and can give an excellent treatment effect to the user.

  In addition, in the massage machine according to the embodiment, the tilting angle of the seat portion 12 is maintained as it is after the seat portion 12 is tilted upward from the initial position, but this is not a limitation. If the leg support 15 is tilted while the inclination angle of the seat 12 is maintained, the leg will rise too much and may be unreasonable depending on the user, so the leg support 15 is tilted upward. In parallel with this, the inclination angle of the seat 12 is reduced to such an extent that the tension of the back of the leg is not greatly affected, and the leg height in the state where the leg support 15 is raised to the maximum. It is also possible to suppress this, and a stretch effect can be appropriately obtained with a posture that is comfortable for the user.

(Seventh embodiment for reference of the present invention)
A massage machine according to a seventh embodiment which is a reference of the present invention will be described with reference to FIG. 22 and FIG.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, the difference is that the control unit 40 tilts the seat 12 upward to bring the user to an appropriate posture and inflates the leg air cell of the leg support unit 15 to lift the leg. Then, the backrest 13 is tilted backward and tilted, and the upper body of the user is largely bent backward to perform treatment for tensioning the abdominal muscles of the user, such as abdominal muscle exercise (control) Do).
The points other than the control related to the tilting of the seat portion 12 and the backrest portion 13 and the operation of the leg air cell for the purpose of giving a state such as abdominal muscle movement and the case of the first embodiment are as follows. It is the same, and detailed description is omitted.

In the treatment state, first, the seat portion 12 is tilted upward, and the leg air cell of the leg support portion 15 is inflated to hold the leg, thereby holding the leg portion of the user so as not to move (see FIG. 22). Thereafter, when the reclining angle of the backrest portion 13 is increased, the upper body is largely bent backward as the backrest portion 12 is tilted while the lower body side is maintained in position on the seat portion 12. A force to stretch the abdominal muscles of the user is applied (see FIG. 23). If the inclination angle of the seat and the backrest is maintained for a predetermined time and the posture of the user is maintained, a load such as so-called abdominal exercise is applied to the abdomen, and the abdominal muscles can be trained.
In this case, it is preferable that the backrest portion 13 is tilted to the limit of the backward tilt or the vicinity thereof, and the upper body of the user is placed in a supine posture because a large tension can be given to the abdominal muscles.

  In the treatment state, the lower body side of the user is held, but the upper body side can be moved on the backrest part 13, so that the user can raise or lower the upper body as necessary. If the operation like the so-called abdominal muscle exercise is repeated, the load can be further applied and the effect can be enhanced. By tilting the seat portion 12 so that the legs are in an appropriate positional relationship, the effect of abdominal muscle exercise can be obtained with a comfortable posture without placing a burden on the waist.

(Eighth embodiment serving as a reference of the present invention)
A massage machine according to an eighth embodiment which is a reference of the present invention will be described with reference to FIGS.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, the difference is that the control unit 40 tilts the seat 12 upward to bring the user to an appropriate posture and the leg air cells 75, 76, 77 of the leg support unit 15. The leg is clamped by inflating 78, and then the leg support 15 is tilted downward from the state where the leg support 15 is raised, thereby executing stretch treatment for extending the leg of the user.

  The points other than the tilting of the seat 12 and the leg support 15 for the purpose of stretching the leg and the control related to the operation of the leg air cell are the same as in the case of the first embodiment. The detailed explanation is omitted.

  The lower knee portion of the leg on the leg support portion 15 is located closest to the foot support portion 15c in a state where the inclination angle of the seat portion 12 and the leg support portion 15 is set so that the leg is straightened. When the degree of bending is increased, the lower knee portion of the leg is separated from the foot support portion 15c accordingly.

That is, when the leg support 15 is tilted to reduce the angle between the seat 12 and the leg support 15 so that the leg is extended to a state where the knee is bent a lot, the leg support 15 is accordingly increased. The lower part from the knee of the leg is shifted to the knee naturally. In this case, the leg air cell 75, 76, 77, 78 of the leg support unit 15 is expanded in advance so that the leg is held by the leg support unit 15, and the leg support unit 15 is replaced with the seat 12 and the leg support unit 15. If the leg is tilted so that the angle between the leg and the leg is smaller, the part where the leg is held is forcibly positioned closer to the foot support part than the position shifted to the original knee. Adds power to extend this.
Thus, as the leg support 15 is tilted, a stretch effect by stretching can be imparted to the leg. In other words, the leg support portion 15 is used to perform a stretch treatment on the legs.

  Next, the operation of each part in the leg stretch treatment with the massage machine according to the present embodiment will be described. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest 13 and the like are completed, and an operation state instruction such as a massage course is input by the user, and various massage operations are executed. In particular, it is assumed that the control unit 40 is about to perform a stretch treatment on the leg.

  First, the controller 40 operates the seat actuator 12d to extend or contract the seat 12, and moves the front of the seat frame 12b of the seat 12 up or down at one end of the seat actuator 12d. The seat 12 is tilted until it reaches a preset tilt angle corresponding to the treatment, for example, a predetermined angle within a range of 15 to 37 ° with respect to the horizontal plane.

  Further, the control unit 40 extends the leg support unit actuator 15d and pushes the leg support unit 15 at one end of the leg support unit actuator 15d to tilt the leg support unit 15 upward. The control unit 40 sets the leg support 15 to a stretch treatment starting position where the leg is sufficiently stretched without bending, preferably the angle formed between the leg support 15 and the seat 12 is about 180 °. Tilt to a position (see FIG. 24).

  Thereafter, the control unit 40 causes the leg support unit 15 to supply air to the leg air cells 75, 76, 77, 78 located on both sides of the leg to expand the air cell. With the expansion of the leg air cells 75, 76, 77, 78, the calf portions of the legs are sandwiched from both sides by the air cells and are restrained by the leg receiving portions 15b.

  In a state where the leg air cells 75, 76, 77, 78 are sufficiently expanded and the calf portion is sandwiched and restrained, the control unit 40 operates the leg support unit actuator 15d to contract the leg support unit 15, The leg support portion 15 is tilted downward while allowing the leg support portion actuator 15d to descend (see FIG. 26).

  Thus, by tilting the leg support 15 downward and increasing the bending of the leg, the lower knee part of the leg naturally moves upward with the knee as the bending of the leg proceeds with respect to the leg support 15. By trying to shift and staying with the leg air cells 75, 76, 77, 78 of the leg support 15, a force is applied to the leg to pull it relatively, and the leg is in tension. That is, a load such as a stretching exercise, in which the leg is strongly pulled and tensioned to the toe side, is applied to the leg.

  Thereafter, when the angle of the leg support portion 15 and the seat portion 12 reaches the predetermined angle of the preset treatment limit as the tilt of the leg support portion 15 proceeds, the control unit 40 moves the leg support portion actuator. 15d and a control command for stopping the operation are sent to the leg air cell supply / discharge control mechanism. Thereafter, the leg support portion actuator 15d is stopped and the tilting of the leg support portion 15 is stopped.

  In this way, the tilting of the leg support 15 is stopped without exceeding the stretch treatment strength selected and set in advance, and stretch with an appropriate treatment strength becomes possible. Prior to tilting the leg support 15 and extending the leg, the seat 12 is tilted at an appropriate tilt angle so that the front is up, so that the body can be displaced. It is difficult to occur, and the state in which the stretch treatment is performed on the leg is surely maintained, and stable and efficient treatment can be performed.

  The control unit 40 stops the leg support unit actuator 15d and contracts the leg air cells 75, 76, 77, 78 by discharging air to release the legs from the sandwiched state, and returns the legs to a state in which the legs can be moved freely. Thereafter, the control unit 40 ends the stretch treatment or tilts the leg support portion 15 to the start position of the stretch treatment again, and repeats the same treatment process a plurality of times.

  As described above, when the leg support unit 15 is tilted downward as a stretch treatment for the legs, the massage machine according to the present embodiment sandwiches the legs with the leg air cells 75, 76, 77, 78 in advance. Since it is in a state of being held and fixed on the receiving portion 15b, the leg naturally tilts upward with respect to the leg support portion 15 as the leg support portion 15 is tilted downward to bend the leg. By using this, a state in which the leg is efficiently stretched can be obtained, the treatment relating to the leg stretch can be performed smoothly and appropriately, and an excellent treatment effect can be imparted to the user.

  In the massage machine according to the above-described embodiment, the leg is stretched by simply tilting the leg support 15 downward from the stretch treatment start position while holding the leg between the leg air cells 75, 76, 77, 78. In addition to this, the control unit 40 operates the leg receiving unit actuator 19 of the leg support unit 15 in parallel with tilting the leg support unit 15 downward, so that the legs of the leg support unit 15 are operated. The receiving portion 15b may be moved gradually toward the side away from the seat portion 12 with respect to the base portion 15a, and the position of the leg air cell built in the leg receiving portion 15b may be moved to further promote the extension of the legs. It is possible to improve the efficiency of treatment.

  Also in this case, when the angle formed between the leg support portion 15 tilting downward and the seat portion 12 reaches a predetermined angle that is a predetermined treatment limit, the operation of the leg support portion actuator 15d is stopped and the leg air cell is contracted. At the same time as starting, the control unit 40 stops the operation of the leg receiving unit actuator 19 to stop the stretch treatment.

(Ninth embodiment for reference of the present invention)
A massage machine according to a ninth embodiment which serves as a reference of the present invention will be described with reference to FIGS.
In each of the drawings, as in the first embodiment, the massage machine according to the present embodiment includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. On the other hand, as a different point, a clamping air cell 79 that presses the thigh of the user from the side is disposed on the inner side of the armrest 14 on the side of the seat 12, and the control unit 40 is In a state in which the clamping air cell 79 is inflated and the thigh is pressed from the side and is clamped from both sides, the seat 12 is tilted upward, and the buttocks are seated back against the thigh that is partially restrained. By moving it to the 13th side, treatment such as stretching is performed on the thigh of the user.

  Aside from providing the clamping air cell 79 on the inner side of the armrest 14 and controlling the tilting of the seat 12 and other purposes for the treatment of the thigh and the operation of the clamping air cell 79, This is the same as in the case of the first embodiment, and a detailed description thereof will be omitted.

  The clamping air cell 79 can be inflated and contracted by air supply and discharge by the air pump 70 on the inner side of the left and right armrests 14 facing the side surfaces of the thighs of the user seated on the seat 12. It is the structure arranged. The sandwiching air cells 79 are arranged in pairs on the left and right so that the left and right thighs can be pressed and restrained in the expanded state.

  Next, operation | movement of each part in the treatment to the thigh with the massage machine which concerns on this embodiment is demonstrated. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest 13 and the like are completed, and an operation state instruction such as a massage course is input by the user, and various massage operations are executed. In particular, it is assumed that the control unit 40 is about to perform treatment on the thigh.

  And before starting the operation control of each part related to treatment, the control unit 40 makes the inclination angle of the seat part 12 with respect to the horizontal plane stable on the minimum angle of the inclination angle adjustment range of the seat part related to treatment, that is, on the seat part. If the angle is not 10 ° to 15 °, which is the minimum inclination angle that can hold the user, the seat actuator 13d is operated, and the inclination angle of the seat portion 12 is set to the minimum angle. Tilt until. The seat position (see FIG. 27) at which the inclination angle of the seat 12 is the minimum angle is the initial position related to the treatment of the seat 12.

  First, the control unit 40 inflates the air cell by supplying air to the sandwiching air cell 79 located on both sides of the thigh (see FIG. 28). With the expansion of the sandwiching air cell 79, the thighs of both legs are sandwiched from both sides by the air cell.

  In a state where the clamping air cell 79 is sufficiently expanded and the thigh is clamped, the control unit 40 operates and extends the seat actuator 12d with respect to the seat 12 in the initial position in treatment, The front part of the seat part frame 12b of the seat part 12 is pushed up by one end part of the seat part actuator 12d, and the seat part 12 is tilted upward. The control unit 40 tilts the seat 12 until it reaches a preset tilt angle for the treatment of the thigh, for example, a predetermined angle within a range of 33 to 37 ° with respect to the horizontal plane (see FIG. 29). .

  Due to the tilting of the seat 12, the center of gravity of the user sitting on the seat 12 moves toward the backrest 13, and the back of the user is more closely attached to the backrest 13 as the position of the center of gravity changes. To do. At the same time, the user's buttocks shift toward the backrest 13 on the seat 12, and the thighs are pulled toward the backrest 13 with the shift of the buttocks toward the backrest 13 side. It becomes a state.

  When the clamping air cell 79 has a strong clamping pressure, the thigh is restrained as it is, and thus the clamped portion of the thigh does not move, so that the pulled thigh is relatively stretched. Can give a stretch effect to the thigh. On the other hand, when the clamping pressure of the clamping air cell 79 is weak, the thigh moves while receiving resistance due to the pressure of the air cell, and the pressure of the clamping air cell 79 is used as resistance. The same thigh stimulation is applied to the receiving thigh.

  In this way, as a treatment for the thigh, the thigh is previously clamped by the clamping air cell 79, and then the seat 12 is tilted upward, so that the buttocks are naturally shifted downward, that is, closer to the backrest 13. Utilizing the desired properties, it will be possible to obtain a state where the treatment of the thigh is efficiently performed, the thigh treatment can be performed smoothly and appropriately, and the treatment effect excellent for the user Can be granted.

  In addition, when the thigh is pulled due to the shift of the buttocks, the control unit prevents the upper body part above the buttocks from moving in such a direction as to absorb the shift of the buttocks and weaken the treatment effect on the thigh. 40 actuates the backrest actuator 13d, moves the lower portion of the backrest portion 13 forward relative to the front portion of the seat portion 12 to increase the reclining angle, that is, tilts the backrest portion 13 to the side to be tilted, It is desirable to make the upper body part difficult to move while making it easier to shift to the backrest side.

  In addition, a waist holding air cell 74a for pressing and holding the waist part of the user is separately provided on both sides of the backrest part 13 (see FIG. 27), and the waist holding air cell 74a is inflated to It can also be configured to be pressed and clamped from the left and right and held on the backrest portion 13, and when the seat portion 12 is tilted, the upper body of the upper body becomes difficult to move relative to the backrest portion 13 by being pressed by the waist clamping air cell 74 a. The effect of extending the thigh can be further enhanced.

  In this case, the leg support unit 15 further holds the leg with the built-in leg air cell, and then operates the leg support unit actuator 15d to tilt the leg support unit 15 downward so that the thigh is further twisted. The leg is moved so as to extend (see FIG. 30), or the leg receiving portion actuator 19 of the leg supporting portion 15 is operated to move the leg receiving portion 15b of the leg supporting portion 15 away from the seat portion 12 with respect to the base portion 15a. By moving little by little and moving the lower knee part of the leg clamped by the leg air cell (see FIG. 31), the thigh can be further stretched. Efficiency will be improved.

(Tenth embodiment for reference of the present invention)
A massage machine according to a tenth embodiment which is a reference of the present invention will be described with reference to FIGS. 32 and 33.
As in the ninth embodiment, the massage machine according to the present embodiment in each of the drawings includes each part forming a chair, an actuator for tilting them, various treatment mechanisms, and a control unit for controlling these operations. Thus, the treatment is performed such as stretching on the thigh of the user. On the other hand, the difference is that the front of the seat 12 is raised and the inclination angle of the seat 12 with respect to the horizontal plane is increased. When the seat is tilted downward, the clamping air cell 79 on both sides of the seat is displaced forward relative to the thigh of the user. 79 is inflated, the thigh is pressed from the side, and is clamped from both sides, and the seat 12 is tilted downward to obtain a state in which the air cell moves the thigh forward. Execute stretching and other treatments It is intended.

  The points other than the control relating to the tilting of the seat 12 for the treatment of the thighs and the operation of the clamping air cell 79 are the same as those in the ninth embodiment, and detailed description will be given. Is omitted.

  As in the ninth embodiment, the sandwiching air cell 79 is inflated by air supply / discharge by the air pump 70 on the inner side of the left and right armrests 14 facing the side surfaces of the thighs of the seated user. Each of the components is arranged to be contractible, and detailed description thereof is omitted.

  Next, operation | movement of each part in the treatment to the thigh with the massage machine which concerns on this embodiment is demonstrated. As a premise, the massage machine 1 is turned on when the user is seated on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight of the user Preparation operations before starting massage such as body shape detection, reclining angle adjustment of the backrest 13 and the like are completed, and an operation state instruction such as a massage course is input by the user, and various massage operations are executed. In particular, it is assumed that the control unit 40 is about to perform treatment on the thigh.

  The controller 40 first operates and extends the seat actuator 12d, pushes up the front portion of the seat frame 12b of the seat 12 at one end of the seat actuator 12d, and tilts the seat 12 upward. The control unit 40 tilts the seat 12 until it reaches a preset tilt angle, for example, a predetermined angle within a range of 33 to 37 ° with respect to the horizontal plane (see FIG. 32).

  By increasing the inclination angle of the seat portion 12 in this way, the center of gravity of the user sitting on the seat portion 12 moves closer to the backrest portion 13, and the back of the user is seated with the change in the position of the center of gravity. A state in which the upper part of the upper part of the waist part of the user is positioned and becomes hard to move is obtained by being closely adhered to the part 13.

  Subsequently, the control unit 40 supplies air to the sandwiching air cell 79 located on both sides of the thigh to inflate the air cell. With the expansion of the sandwiching air cell 79, the thighs of both legs are sandwiched from both sides by the air cell.

  In a state where the clamping air cell 79 is sufficiently expanded and the thigh is clamped, the control unit 40 operates the seat actuator 12d to contract and seat the seat 12 connected to one end of the seat actuator 12d. The front part of the part frame 12b is lowered and the seat part 12 is tilted downward. The control unit 40 tilts the seat 12 until it reaches a preset tilt angle corresponding to the treatment, for example, a predetermined angle within a range of 10 to 15 ° with respect to the horizontal plane (see FIG. 33).

  At the same time, the control unit 40 operates and contracts the backrest actuator 13d, and closes the lower portion of the backrest portion 13 to the front portion of the seat portion 12 with the backrest actuator 13d, so that the control portion 40 tilts backward to the backrest portion 13. The tilting component is applied, and the tilting angle of the backrest 13 that tries to tilt in the direction that occurs forward in conjunction with the tilting of the seat 12 is maintained or tilted by a predetermined angle in the direction that it is actually tilted backward.

  When the seat 12 is tilted, the thigh of the user who holds the upper body part is located on the seat 12 but tends to maintain a position near the backrest 13. In other words, the tilt of the thigh occurs around the waist and does not accurately follow the tilt of the seat at different tilt center positions. The body of the patient who can tolerate slight expansion and contraction and displacement in the part absorbs changes in the support state accompanying tilting of the seat at each part of the body, and minimizes the movement that actually appears on the surface of the body As a result, the thigh can substantially maintain the position before tilting the seat in the front-rear direction even after the seat is tilted.

  On the other hand, the air cell 79 for clamping located in the inner part of the armrest part 14 that tilts downward together with the seat part 12 is accurate as a mechanism of the massage machine around the shaft support position of the seat part without expansion and contraction or displacement. Assuming that the thigh is not in contact with the thigh, it is in a state of being relatively displaced forward with respect to the thigh. Since the thigh is actually clamped by the clamping air cell 79, the thigh is pulled forward as the clamping air cell 79 is relatively displaced forward.

  When the clamping air cell 79 has a strong pressure, the thigh is constrained as it is, and thus the clamped portion of the thigh moves relative to the air cell so that the tensioned thigh is stretched. Can give a stretch effect to the thigh. On the other hand, when the clamping pressure of the clamping air cell 79 is weak, the thigh tries to stay in the original position while receiving the pressure of the air cell, and continuously receives the pressure of the clamping air cell 79 that moves relatively. The thigh is subjected to the same stimulus as that of the brush.

  In this way, as a treatment for the thigh, after the thigh is sandwiched in advance by the clamping air cell 79, the seat 12 is tilted downward so that the seat tilts between the body and the mechanism part. Utilizing the nature of the difference in the positional change that accompanies it, it will be possible to obtain a state where treatment such as stretching of the thigh is efficiently performed, and the treatment of the thigh can be executed smoothly and appropriately. An excellent treatment effect can be imparted.

  When the thigh is pulled by the sandwiching air cell 79, the control unit 40 is provided with a backrest so that the upper body part above the waist does not shift forward and weaken the effect of treatment on the thigh. Actuating the actuator 13d and moving the lower part of the backrest part 13 forward relative to the front part of the seat part 12 to increase the reclining angle, that is, tilting to the side to be tilted, so that the upper body part is difficult to move. Is desirable.

  In addition, as in the ninth embodiment, waist holding air cells 74a for pressing and holding the waist portion of the user are separately provided on both sides of the backrest portion 13 (see FIG. 27), and this waist holding air cell 74a. Can be configured such that the upper waist portion is pressed and clamped from the left and right sides and held on the backrest portion 13, and the upper waist portion can be pressed by the waist clamping air cell 74 a when the seat portion 12 is tilted downward. The upper body is prevented from moving with the thigh, and the effect of extending the thigh can be further enhanced.

  Along with the treatment such as stretching of the thigh, the leg support unit 15 supports the leg by operating the leg support unit actuator 15d after sandwiching the leg with the built-in leg air cell as in the ninth embodiment. The leg 15 is tilted downward, the leg is pulled so as to extend the thigh more, or the leg receiving part actuator 19 of the leg supporting part 15 is operated, and the leg receiving part 15b of the leg supporting part 15 is moved to the base part 15a. It can also be configured to further move the thigh by further moving toward the side away from the seat 12 and moving the leg below the knee held by the leg air cell so as to pull the thigh. The efficiency of the treatment can be further improved.
