The roller mechanism 69 is provided at a sole step of the footrest 5. The drive shaft 71 has a left-right direction as an axial direction, and is connected to a motor 70 via a speed reducer 74 housed in a gear case 73.

  The roller mechanism 69 has a plate-shaped bracket 75 for fixing the motor 70, and the motor 70 is fixed such that the output shaft 70a of the motor 70 is oriented in the left-right direction. The bracket 75 also functions as a bearing that rotatably supports the drive shaft 71. The gear case 73 houses a speed reducer 74 that reduces the power of the motor 70 and transmits the power to the drive shaft 71.

  A treatment element 72 is provided on the drive shaft 71 so as to exist over a predetermined distance. The treatment element 72 includes a projection group 76 having a plurality of projections 76a in the left-right direction, and a support portion 77 that supports the projection group 76. The plurality of protrusion groups 76 are provided in the circumferential direction of the drive shaft 71 so as to be present over a predetermined distance from the drive shaft 71 by the support portion 77. Further, the projection group 76 is attached to the support portion 77 so as to be rotatable around a left-right axis. Further, the respective protrusions 76a of the adjacent protrusion group 76 are positioned to be shifted in the left-right direction, and the protrusions 76a are in a staggered arrangement in plan view as a whole of the treatment element 72. When the drive shaft 71 rotates by driving the motor 70, the roller mechanism 69 configured as described above rotates the treatment element 72 to massage the sole. In addition, since the protrusions 76a are arranged in a staggered manner, it is possible to apply an acupressure action to the sole of the foot.

  Further, the roller mechanism 69 is provided with an advance / retreat mechanism 78 having a drive unit for moving the roller mechanism 69 toward and away from the lower limb. The advance / retreat mechanism 78 includes a hinge part 80 attached to the sole step, and a driving air cell 79 as a driving part that opens and closes the hinge part 80. The hinge portion 80 has a lower plate 80a, and an upper plate 80b connected to the rear side of the lower plate 80a via a left-right swing shaft 80c. A driving air cell 79 is provided therebetween. The roller mechanism 69 is attached to the upper plate 80b constituting the hinge section 80. More specifically, bracket 75 and gear case 73 constituting roller mechanism 69 are fixed to upper plate 80b.

  The driving air cell 79 expands and contracts when air is supplied and exhausted from the air supply and exhaust device 51, and is substantially flat when contracted. As described above, since the reciprocating mechanism 78 is constituted by the hinge portion 80 and the driving air cell 79, the reciprocating mechanism 78 can be reduced in thickness. The reciprocating mechanism 78 is provided substantially at the center in the left-right direction and between the pair of treatment elements 72. Therefore, the existence of the advance / retreat mechanism 78 does not hinder the operation of the treatment element 72.

  When air is supplied to the driving air cell 79, the hinge portion 80 is opened, and the roller mechanism 69 attached to the hinge portion 80 swings upward with the rear side as a fulcrum. On the other hand, when air is exhausted from the driving air cell 79, the hinge portion 80 closes, and the roller mechanism 69 attached to the hinge portion 80 moves downward with the rear side as a fulcrum due to its own weight or a load from the user. Rocks. The operations of the roller mechanism 69 and the driving air cell 79 are controlled based on a command from the control unit 50, and the roller mechanism 69 promotes blood circulation at the distal end of the user while the user is seated on the seat 2. It is possible to function as a blood circulation promoting operation unit that performs a blood circulation promoting operation.

  By operating the advance / retreat mechanism 78 in this manner, the amount by which the protrusion group 76 of the roller mechanism 69 is pushed out changes. Therefore, the intensity of massage by the roller mechanism 69 can be changed by changing the operation amount of the advance / retreat mechanism 78. Further, in the present embodiment, since the roller mechanism 69 is vertically swung with the rear side as a fulcrum, a stretching action with the ankle as a fulcrum can be given to the lower limb. In addition, from the viewpoint that the intensity of the massage can be changed, the roller mechanism 69 may be raised substantially perpendicularly to the inner bottom surface of the lower footrest 15, or may be vertically swung about the front side as a fulcrum.

  A remote controller (remote controller) 60 having a plurality of operation buttons (not shown) is connected to the control unit 50. By operating the remote controller 60 by himself / herself, the user can operate various operating means included in the chair-type massage machine 1, and explanations and guidance corresponding to each operation are displayed on the display of the remote controller 60 (not shown). Is displayed.

  Next, a stiff shoulder elimination course, which is one of the treatments that can be performed by the chair-type massage machine 1 as described above, will be specifically described.

[Stiff shoulder elimination course]
FIG. 8 is a schematic diagram showing a mode of massage performed in the stiff shoulder elimination course in the present embodiment. When the user operates a predetermined button on the remote controller 60, a stiff shoulder elimination course is started. In the stiff shoulder elimination course, the control unit 50 controls the backrest unit 3 to perform a backward leaning operation in which the backrest unit 3 leans backward and the footrest 5 rises. After the backward tilt operation, the control unit 50 detects the shoulder position of the user by the treatment mechanism 9a.

  Next, the control unit 50 controls the back heater 25 to perform a warming operation on the user's neck or shoulder. The warming operation is performed, for example, for one minute. As described above, since the back heater 25 is provided at the left and right central portions of the backrest portion 3, the center of the user's body can be warmed by the back heater 25, and the heating effect can be enhanced. In addition, since the back heater 25 can be provided at a position that does not interfere with the kneading balls 27 of the treatment mechanism 9a that approaches and separates, damage to the back heater 25 can be prevented.

  When the back heater 25 warms the neck or the shoulder, the treatment mechanism 9a performs an operation of pushing the heater 25 up to the user side. Specifically, the control unit 50 controls the treatment mechanism 9a to be positioned near the shoulder position (near the heater 25 position), and to expand the pressing air cell 28 of the treatment mechanism 9a at that position. Thereby, the back heater 25 can be pressed against the body by the treatment mechanism 9a, and an effect like moxibustion can be provided.

  The control unit 50 also performs the blood circulation promotion operation of the blood circulation promotion operation unit (the hand heater 26 or the roller mechanism 69) when performing the warming operation of the user's neck or shoulder by the back heater 25. Thus, a blood circulation promoting operation for promoting blood circulation at the end of the user during the warming operation by the back heater 25 is also performed. By performing the blood circulation promoting operation also at a part other than the neck or the shoulder, it is possible to prevent the user from being raised as compared with the case where only the neck or the shoulder is warmed.

  The control unit 50 may perform the blood circulation promoting operation using both the hand heater 26 and the foot roller mechanism 69, or may perform the blood circulation promoting operation using only one of the hand heater 26 and the hand heater 26. The blood circulation promoting operation may be performed by alternately operating the roller mechanism 69 and the roller mechanism 69. Further, a heater may be provided on the seat 2 or the footrest 5 to warm the whole body. When the heater is provided on the footrest 5, for example, the heater may be provided on the surface of the air cell 7l that sandwiches the ankle. In this case, by expanding the air cell 7l, a blood circulation promoting operation of warming the ankle while pressing the heater against the ankle can be realized. Further, the blood circulation promoting operation may be realized by vibrating the whole body using the air cell 7d of the hand or the seat vibrator 8a and the back vibrator 8b. As described above, the blood circulation promoting operation is not particularly limited as long as the blood circulation is promoted by the warming operation by the hand heater 26 or the light stimulation by the roller mechanism 69, the air cell 7, the vibrator 8, and the like.

  The control unit 50 controls the stretching operation unit 22 (the air cells 7n and 7o) to perform the first stretching operation after the heating operation on the neck or the shoulder of the user (after a predetermined time has elapsed from the start of the heating operation). . The control unit 50 controls to perform the first stretching operation by alternately inflating the first air cells 7n and the second air cells 7o functioning as the stretching operation unit 22. Thus, the levator scapula, which causes stiff shoulders, can be efficiently stretched. Further, by performing the first stretching operation after the warming operation by the back heater 25, the first stretching operation is performed in a state where the blood vessels of the whole body of the user are expanded, so that the stretching effect can be further enhanced. In addition, the control part 50 controls so that the backrest part 3 may stand and the footrest 5 may fall before starting the 1st stretching operation. By setting the user's back upright at the time of the first stretching motion, the stretching effect of the stretching motion portion 22 on the levator scapula can be further enhanced.

  FIG. 9 is a diagram schematically illustrating a portion where the stretching operation section 22 acts on the human body. As shown in FIG. 9, the levator scapula muscles M1 and M2 are muscles that pull up the scapula, and exist so as to connect the first to fourth cervical vertebrae with the upper end portions of the left and right scapulae. Therefore, by inflating the first air cell (right air cell) 7n, a force can be applied to the upper part A1 of the levator scapula M1 on the right side to extend the levator scapula muscle M1 to the upper left. Similarly, by inflating the second air cell (left air cell) 7o, a force can be exerted on the upper part A2 of the left levator cruvis muscle M2 to extend the levator scapula muscle M2 to the upper right.

  When performing the first stretching operation in the stretching operation unit 22, the control unit 50 controls the treatment mechanism 9a so as to maintain the treatment mechanism 9a at a position where the shoulder of the user is prevented from moving upward or forward. Specifically, the control unit 50 positions the treatment mechanism 9a at a position above the shoulder of the user, and inflates the pressing air cell 28 of the treatment mechanism 9a at that position to move the treatment mechanism 9a toward the user. Stop when pushed up. According to this, the treatment mechanism 9a can prevent the position of the body of the user from being displaced from the backrest portion 3 during the first stretching operation at the position above the shoulder of the user by the treatment mechanism 9a. The first stretching operation by the part 22 can be made to act on the user efficiently.

  In the example of FIG. 8, the operation of expanding and contracting the first air cell 7n on the right as a first stretching operation, and then repeating the operation of expanding and contracting the second air cell 7o on the left a plurality of times (three times). The operation is illustrated. However, the present invention is not limited to this. For example, an operation may be performed in which the right first air cell 7n is expanded and contracted a plurality of times, and then the left second air cell 7o is expanded and contracted a plurality of times, or a combination of these operations. Also, the number of repetitions is not particularly limited.

  During the first stretching operation, the warming operation by the back heater 25 may be continued as shown in FIG. In the example of FIG. 8, the blood circulation promoting operation is stopped after the first stretching operation is started, but the blood circulation promoting operation may be continuously performed. On the other hand, during the first stretching operation in the stretching operation unit, the control unit 50 controls so that the massage to the shoulder of the user by the treatment mechanism 9a is not performed. Thereby, during the first stretching operation in the stretching operation section, the user's consciousness can be concentrated on the stretching, and the stretching effect can be further enhanced. In the first stretching operation, the effect is enhanced by the user having an active sensation (a consciousness to actively perform the first stretching operation). Therefore, the effect of the first stretching operation can be enhanced by concentrating the location where the strong stimulus acts on the user during the first stretching operation on the levator scapula.

  In the present embodiment, when the first stretching operation is started, an announcement that the stretching is performed by voice and the content of the stretching are announced. Therefore, in the present embodiment, the chair-type massage machine 1 includes an audio output unit (speaker) 54 that can output a predetermined audio based on a command from the control unit 50. The audio output unit 54 may be provided in a predetermined place such as the headrest 6, the backrest 3, the armrest 4, or the seat 2, or may be provided in the remote controller 60. Further, in addition to or instead of the voice announcement, a message indicating that stretching is to be performed and the content of the stretching may be displayed on the screen. For this reason, the chair-type massage machine 1 may include a screen display unit (such as a liquid crystal monitor) that can output a predetermined screen display based on a command from the control unit 50. The screen display unit is provided at a place where the user can easily see, such as the remote controller 60 or the upper part of the armrest 4. By announcing that the first stretching operation is performed and the content of the first stretching operation, the user can be made more conscious of the first stretching operation.

  As described above, in the present embodiment, a treatment element that massages each part of the user is provided in addition to the treatment mechanism 9a. In such a chair-type massage machine 1, during the first stretching operation, it is preferable that the control unit 50 does not perform the massage operation not only on the shoulder but also on the periphery of the shoulder. For example, the control unit 50 controls so that a massage operation is not performed on the treatment element (the treatment mechanism 9b, the air cell 7c) provided in the backrest unit 3. Further, during the first stretching operation, the control unit 50 may control so that the massage operation is not performed on the air cells 7e to 7h other than the air cell 7d provided on the hand among the air cells provided on the armrest 4. Of course, during the first stretching operation, all the treatment elements other than the stretching operation unit 22 may be stopped.

  After the first stretching operation in the stretching operation unit 22, the control unit 50 controls the treatment mechanism 9a to massage the shoulder of the user. According to the above configuration, before performing the massage to the shoulder of the user, the first stretching operation of tilting the head of the user in the left-right direction and / or the front is performed, so that the shoulder girth causing the stiff shoulder is performed. The massage to the shoulder can be performed after softening the muscle. Therefore, a massage with a higher stiff shoulder eliminating effect can be performed.

  Note that, before performing the massage, the control unit 50 controls the backrest unit 3 to perform a backward leaning operation in which the backrest unit 3 leans backward and the footrest 5 rises. By placing the user in a relaxed position, the effect of the massage can be enhanced. Also, during the massage operation on the shoulder, the warming operation by the back heater 25 may be continued as shown in FIG. In the example of FIG. 8, the blood circulation promoting operation is stopped during the massage operation, but the blood circulation promoting operation may be continuously performed. Further, the massage operation at a portion other than the shoulder may be performed in parallel. After the end of the massage operation, the control unit 50 performs a standing operation in which the backrest unit 3 stands up and the footrest 5 descends, and ends the execution of the shoulder stiffness eliminating course.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said Embodiment, A various improvement, change, and correction are possible within the range which does not deviate from the meaning.

  For example, in the stiff shoulder elimination course of the above embodiment, after the warming operation around the shoulder by the back heater 25, the first stretching operation in the stretching operation unit 22 is performed, and after the first stretching operation, the treatment mechanism 9a operates. The aspect of performing the massage operation on the shoulder has been described. However, the present invention is not limited to this. For example, only any two of the above three operations may be performed. For example, the first stretching operation may be performed after the warming operation, the massage operation may be performed after the warming operation, or the massage operation may be performed after the first stretching operation.

  Further, the warming operation may be performed after the first stretching operation is performed. Further, after performing the massage operation, the warming operation or the first stretching operation may be performed. That is, by appropriately combining the order of at least two of the three operations, a stiff shoulder elimination course can be generated. Further, the blood circulation promoting operation may not be performed depending on the embodiment.

  Further, in the above embodiment, an example was described in which the mechanical treatment mechanism 9a was provided as a treatment element for performing massage to the shoulder, but the present invention is not limited to this. For example, the same stiff shoulder elimination course as that of the present embodiment can be applied to a chair-type massage machine in which an air cell capable of performing massage to a shoulder portion is provided in the backrest portion 3.

  Further, in the above-described embodiment, the configuration in which the stretching operation section 22 is attached to the headrest 6 has been illustrated, but the present invention is not limited to this. For example, the backrest unit 3 may be provided with a stretching operation unit 22. Further, the stretching operation section 22 may have a structure other than the air cells 7n and 7o as long as the effect of stretching effectively acts on the levator scapula.

  In the stiff shoulder elimination course, the control unit 50 warps the whole body before or after the first stretching operation in which the user's head in the first air cell 7n and the second air cell 7o is tilted left and right and / or forward. A stretching operation may be performed. 10A and 10B are side views showing a state during the second stretching operation, and FIG. 10A is a side view of the chair-type massage machine, showing a state in which the backrest is raised and the footrest is raised. FIG. 10B is a side view of the chair-type massage machine, showing a state where the backrest is tilted backward and the footrest is lowered.

  The back frame 29 in the backrest portion 3 is supported by the rear portion of the seat frame 13 at a position slightly above the lower end portion thereof via a left-right rotating shaft 3s. At the lower end of the back frame 29, one end of a rotation mechanism (not shown) such as a direct-acting actuator composed of an air cylinder or the like is pivotally supported. The other end of the rotation mechanism is connected to a seat frame. 13 is pivoted. Therefore, when the rotating mechanism extends and contracts, the backrest portion 3 rises and falls backward as the back frame 29 rotates about the rotation axis about the rotation axis 3s. Has become possible.

  The upper end of the footrest 5 provided in front of the seat 2 is supported at the front of the seat frame 13 by a rotating shaft 5s whose axis is oriented in the left-right direction. Then, by the expansion and contraction operation of a rotation mechanism (not shown) such as a direct-acting actuator composed of an air cylinder or the like, the lower portion is moved up and down so that the lower portion rotates in the front-rear direction (vertical direction) about the rotation shaft 5s. It is possible. That is, the footrest 5 is lowered by the contraction of the rotation mechanism, and the lower footrest 15 is positioned below the upper footrest 14. The footrest 5 is raised by the extension of the rotation mechanism, The lower footrest 15 is in a state of being located forward.

  When performing the second stretching operation to warp the whole body, the control unit 50 determines that the chair-type massage machine 1 causes the footrest 5 to rotate slightly forward around the rotation axis 5 s and backrest as shown in FIG. 10A. 10B, the footrest 5 is rotated downward around the rotation axis 5s, and the backrest 3 is rotated around the rotation axis 3s. To the rear. That is, when performing the second stretching operation on the whole body, the footrest 5 and the backrest portion 3 work together so that the angle formed by both of them increases. At this time, the air cells 7j, 7k, 7m provided on the side of the leg of the user in the footrest 5 are inflated to hold the leg of the user in the footrest 5, and the side of the user in the seat 2. It is preferable to inflate the air cells 7g and 7h provided on the sides of the user in the air cell 7b or the armrest 4 provided in the vehicle and hold the upper body of the user on the seat portion 2 and the backrest portion 3.

  In this case, the stretching operation unit includes a rotation mechanism (not shown) of the footrest 5, a rotation mechanism (not shown) of the backrest 3, and air cells 7g, 7h, 7j, provided on the sides of the user. 7k, 7m.

  According to this, by stretching the whole body in addition to stretching to the levator scapula, the whole body can be relaxed and the effect of the massage can be enhanced.
