The massage is performed by releasing the compression.
JP-A-2001-204776 (page 4, FIG. 1)

  However, in the massage machine disclosed in the above publication, when the user sits on such a massage machine, the forearm is inserted into a holding wall provided on the upper part of the armrest, When using the massage machine without the purpose of forearm treatment such as simply using the massage machine as an easy chair or treating a body part other than the forearm because the holding wall cannot be removed from the armrest part In addition, the user had to insert the forearm into the arm holding part.

  When the forearm is inserted into the arm holding unit in this manner, the posture of the user is restricted, and even when the user wants to take another posture, the arm holding unit is in the way and the user It was difficult to take a desired posture.

  The present invention has been made in view of such circumstances, it is possible to treat the forearm of the user if necessary, and when not performing treatment of the forearm, the upper part of the armrest portion An object of the present invention is to provide a chair-type massage device that does not have a portion that interferes with the arm rest and allows a user to take a free posture, and a forearm massage machine used in the chair-type massage device.

  In order to solve the above problems, a chair-type massage device according to the present invention includes an armrest that supports a forearm of a user, and is detachable from the armrest, and the forearm sandwiches the forearm of the user. And a forearm massage machine for applying a pressure stimulus to the body.

  Further, the forearm massage machine according to the present invention can be attached to and detached from an armrest provided on a chair-type massage device, and is configured to apply a pressure stimulus to the forearm with the forearm of the user interposed therebetween. It is characterized by.

  In the present invention, since the forearm massage machine can be attached to and detached from the armrest, when treating the forearm of the user, the forearm massage machine is attached to the armrest and the forearm of the user is treated. When not performing treatment, the forearm massage machine can be removed from the armrest by removing the forearm massage machine from the armrest, and if necessary, the forearm of the user can be treated. There is no portion that obstructs the arm rest at the upper part, and the user can take a free posture.

  In addition, since the forearm massage machine sandwiches the forearm of the user, even when the forearm of the user is pressed, the forearm does not escape in the direction of the pressing, and the pressing stimulation by the forearm massage machine is reliably performed. It can be given to the forearm of the user.

  Further, in the above invention, it is preferable that the forearm massage machine has a configuration in which a length in a longitudinal direction of the armrest is shorter than a length of the armrest. Thereby, the forearm massage machine that is frequently attached and detached can be made small, and the treatment area by the forearm massage machine can be made relatively small. It is possible to apply a local pressing stimulus to a specific location, and it is expected that the treatment effect can be further enhanced.

  Further, in the above invention, it is preferable that the armrest is configured to be able to move the forearm massage machine in a longitudinal direction of the armrest. This makes it possible to adjust the treatment position of the forearm in the longitudinal direction of the armrest.

  In this case, the configuration may be such that the forearm massage machine is automatically moved, or the user may manually move the forearm massage machine.

  Further, in the above invention, it is preferable to further include a lock mechanism for fixing the forearm massage machine to the armrest. Accordingly, the forearm massage machine can be securely fixed to the armrest, and the position of the forearm massage machine can be prevented from becoming unstable while the forearm of the user is being treated.

  Further, in the above invention, the armrest may have a moving means for moving the forearm massage machine in a longitudinal direction of the armrest. In this case, since the forearm massage machine can be automatically moved, the position of the forearm massage machine can be adjusted even more easily. In addition, the forearm massage machine can be moved while applying a pressing stimulus to the forearm, whereby a massage equivalent to a so-called rubbing massage by a masseur or the like can be performed.

  In the above invention, the backrest supporting the upper body of the user, a reclining angle changing means for changing a reclining angle of the backrest, and a reclining angle of the backrest by the reclining angle changing means. In synchronization with the change, the control circuit for controlling the operation of the moving means, in order to move the forearm massage machine in a direction corresponding to the reclining direction of the backrest portion by a distance corresponding to the reclining angle, It is also possible to provide a configuration provided. Thereby, even if the position of the forearm of the user with respect to the armrest is shifted by changing the reclining angle of the backrest, the forearm massager is moved by moving the forearm massage machine in accordance with the shift. The relative positional relationship between the machine and the forearm of the user can be maintained.

  In the above invention, it is preferable that the forearm massage machine includes a fixed support for supporting the forearm of the user when the forearm massage machine is mounted on the armrest. Thereby, when treating the forearm of the user, a pressing stimulus is given to the forearm of the user by a forearm massage machine shorter than the armrest, but at this time, the pressing stimulus of the forearm of the user is given. Since only the applied portion and the vicinity thereof are supported by the fixed support portion, the support can be stably supported as compared with a case where substantially the entire forearm of the user is supported.

  Further, in the case where the forearm of the user is pressed from the opposite side of the support portion by the fixed support portion to give a stimulus, the forearm of the user is pressed against the fixed support portion by the pressing. In addition, since the pressing stimulus is substantially given from the fixed support portion, and since the support area is not relatively large, it is expected that the fixed support portion can also provide the local stimulus to the forearm of the user.

  Further, in this case, the forearm massage machine is configured to be able to move in a direction of approaching or moving away from the fixed support, and a treatment subject supported by the fixed support is provided. A holding portion for holding the forearm between the fixed support portion, an actuator for moving the holding portion in a direction to approach or separate from the fixed support portion, and an opposing portion of the fixed support portion and the holding portion. The medical device may further include a treatment unit provided on at least one side and configured to apply a pressure stimulus to the forearm of the user sandwiched between the fixed support unit and the holding unit.

  In the above invention, the actuator is connected to an air supply / exhaust device for air supply / discharge provided outside the forearm massage machine when the forearm massage machine is mounted on the armrest. Preferably, the treatment section is configured as an air bag, and the treatment section is provided with an air supply / discharge air supply / discharge provided outside the forearm massage machine when the forearm massage machine is mounted on the armrest. Preferably, it is configured as an air bladder configured to be connected to an exhaust device. Thereby, when the forearm massage machine is mounted on the armrest, the actuator and the treatment section can be driven. Further, since the air supply / exhaust device is provided outside the forearm massage machine, the size of the forearm massage machine can be reduced.

  Further, in the above invention, the treatment section has two air bladders arranged side by side in a direction intersecting with a longitudinal direction of the armrest section, at a portion of the holding section facing the fixed support section. The operation of the actuator to move the holding portion in a direction approaching the fixed support portion so that the forearm of the user indicated by the fixed support portion is held by the fixed support portion and the holding portion. Controlling, then, the two air bladders are inflated, and the forearm of the user sandwiched by the fixed support portion and the holding portion is sandwiched in a direction intersecting the longitudinal direction of the armrest portion, The direction in which the operation of the treatment section is controlled, and then the holding section is separated from the fixed support section so that the two air bags sandwiching the forearm of the user are separated from the forearm of the user. To move to A control circuit for controlling the operation of the actuator can be further provided with structure. This makes it possible to perform so-called kneading, in which the forearm of the user is pinched while being pulled.

  In the case of the chair-type massage device and the forearm massage machine according to the present invention, since the forearm massage machine can be attached to and detached from the armrest, when the forearm of the user is treated, the forearm is attached to the armrest. When the massage machine is attached and the forearm of the user is not treated, the forearm of the subject can be treated if necessary by removing the forearm massage machine from the armrest. When the treatment is not performed, there is no portion that obstructs the arm rest above the armrest, and the user can take a free posture.

  In addition, since the forearm massage machine sandwiches the forearm of the user, even when the forearm of the user is pressed, the forearm does not escape in the direction of the pressing, and the pressing stimulation by the forearm massage machine is reliably performed. The present invention has an excellent effect, for example, it can be given to the forearm of the user.

FIG. 1 is a perspective view showing the overall configuration of a chair-type massage device according to Embodiment 1 of the present invention. As shown in FIG. 1, a chair-type massage apparatus 1 according to the first embodiment has a chair shape, and is mainly configured by a seat portion 2, a backrest portion 3, a footrest 4, and an armrest (armrest portion) 5. ing. The seat portion 2 is configured such that a cushion portion 2c having a substantially flat upper surface is disposed on an upper portion of a base (not shown) having legs 2a on both sides of a lower portion thereof. ing. In the cushion portion 2c, an interior material (not shown) made of urethane foam, sponge, or styrofoam is placed on the upper surface of the base, and further, this is made of brushed polyester tricot, synthetic leather, natural leather, or the like. It is configured to be covered with an exterior material (cover) made of.

  The upper front side of the seat 2 (refers to the front side when viewed from the user sitting on the chair-type massage device 1. In the following, the left indicates the case when viewed from the user sitting on the chair-type massage device 1. An upper end portion of the footrest 4 for massaging the ankle and calf of the user is pivotally mounted on the left side and the right side means the right side as viewed from the user. Thereby, the footrest 4 is rotatable back and forth about its upper end.

  In this footrest 4, side walls 4b and 4c project forward from both sides of a flat lower leg support surface 4a extending downward from the front end of the seat 2 in FIG. The sole support wall 4d protrudes forward in the drawing from the middle and lower ends, that is, the end farthest from the seat 2. Air bags (not shown) are provided inside the side walls 4b and 4c, and these air bags are provided with a pump / valve or the like built in the seat portion 2 or the backrest portion 3 (see FIG. 1). 5) by an air hose (not shown), and is configured to expand or contract by supply and exhaust from the supply and exhaust device 9. Thereby, when the user is seated, the air bag repeatedly inflates and contracts, thereby giving a pressure stimulus to the outer part of the lower leg of the user and the side and upper parts of the foot. I have.

  The lower leg support surface 4a is configured to abut and support the lower leg of the user when the user sits on the chair-type massage device 1. Air bags (not shown) are also provided at a plurality of places on the lower leg support surface 4a, and these are also connected to the air supply / exhaust device 9 via air hoses. Then, these air bladders repeatedly inflate and deflate, so as to give a pressure stimulus to the circumference of the calf and the Achilles tendon of the user.

  Furthermore, when the user sits on the chair-type massage apparatus 1, the sole support wall 4d abuts on the sole of the user and supports the same. A vibrator (not shown) and an air bag (not shown) are provided inside the sole support wall 4d, and the air bag is connected to the air supply / exhaust device 9 via an air hose. Further, the vibrator has a configuration in which an eccentric mass is attached to an output shaft of a DC motor, for example, and can generate fine vibrations when driven. By repeating the inflation and deflation of these air bladders, a pressure stimulus can be given to the sole of the user, and a vibration stimulus can be applied to the sole of the user by operating the vibrator. Can be given.

  A plurality of air bladders are also arranged on the back side of the seat 2. These air bladders are also connected to an air supply / exhaust device 9 via an air hose (not shown), and are configured to expand or contract by air supply / exhaust from the air supply / exhaust device 9. Further, a vibrator (not shown) having the same configuration as that described above is provided on the back side of the center of the seating surface of the seat portion 2. With such a configuration, by repeatedly inflating and deflating the air bag while the user is seated on the seat 2, pressure stimulation can be applied to the buttocks of the user, and the vibrator is driven in the same state. By doing so, a vibration stimulus can be given to the anal part of the user.

  Further, a backrest 3 is provided at the rear of the seat 2. The backrest portion 3 is large enough to support the upper body of the user and prevent a part of the adult's body from protruding outside when the adult having a general physique sits on the chair-type massage apparatus 1. It has a substantially rectangular shape when viewed from the front. The lower end portion of the backrest portion 3 is pivotally supported by a lateral pivot at the rear portion of the seat portion 2, and the backrest portion 3 is pivotable about this pivot so that it can recline forward and backward. I have. Armrests 5 fixed to and supported by the base of the seat 2 are provided on both sides of the backrest 3 respectively. The armrest 5 extends forward from both sides of the backrest portion 3 and has a forearm massage machine 7 described later. The forearm massage machine 7 can be attached to and detached from the armrest 5. When the user sits on the chair-type massage device 1 with the forearm massage machine 7 removed from the armrest 5, the armrest 5 is used as an armrest. It can be used.

  A massage mechanism 6 as shown in FIG. 2 is provided inside the backrest portion 3. FIG. 2 is an exploded perspective view showing the configuration of massage mechanism 6 included in chair-type massage apparatus 1 according to Embodiment 1 of the present invention. The massage mechanism 6 has four roller-shaped treatment elements 10 that apply mechanical stimulation to the body of the user. Further, motors 11 and 12 of DC motors for displacing the treatment element 10 are provided. The treatment element 10 is attached to each of the tips of two V-shaped arms 13. Each arm 13 is attached to two substantially V-shaped connecting rods 14 so as to be rotatable within a predetermined range. Each connecting rod 14 is provided with a fitting hole 15, and the inclined portions 17 provided at both ends of the rotating shaft 16 are loosely fitted in the fitting hole 15. The inclined portion 17 is provided so as to be inclined at a predetermined angle with respect to the rotating shaft 16. A helical gear 18a is coaxially provided at an intermediate portion of the rotating shaft 16, and the helical gear 18a meshes with the worm 18b. Thus, the worm gear mechanism 18 is constituted by the helical gear 18a and the worm 18b.

  A pulley 19a is provided coaxially at one end of the worm 18b, and the pulley 19a and a pulley 19c provided on the output shaft of the motor 11 are connected by a belt 19b. Therefore, the rotational movement of the motor 11 is transmitted to the worm 18b via the belt 19b, and the rotation of the worm 18b causes the rotation shaft 16 to rotate. Then, with the rotation of the rotating shaft 16, the inclined portion 17 is displaced so as to draw a conical trajectory, whereby the connecting rod 14 operates regularly, and the left and right treatment elements 10 are moved right and left so as to approach and separate. And move so as to draw a substantially ellipse in the vertical direction. This is the massage operation of the treatment element 10. Note that the kneading operation of the treatment element 10 includes an operation of moving forward (the user side) when the left and right treatment elements 10 approach and moving backward when the left and right treatment elements 10 separate. In this way, in the kneading operation, the treatment element 10 moves three-dimensionally.

  As shown in FIG. 2, a fitting hole 20 is provided at a lower portion of the connecting rod 14, and a protrusion 22 provided on a connecting member 21 is inserted into the fitting hole 20. The connecting member 21 is provided with a horizontal hole 23, and the eccentric portions 25 provided at both ends of the rotating shaft 24 are loosely fitted into the hole 23. A pulley 26a is coaxially provided at an intermediate portion of the rotary shaft 24, and the pulley 26a is connected to a pulley 26c provided on an output shaft of the motor 12 by a belt 26b. Accordingly, the rotational movement of the motor 12 is transmitted to the rotating shaft 24 via the belt 26b, and the connecting member 21 moves substantially up and down due to the revolution of the eccentric portions 25 at both ends of the rotating shaft 24. As a result, since the connecting rod 14 reciprocates around the fitting hole 15, the treatment element 10 reciprocates substantially up and down in an arc. When the motor 12 is rotated at a constant speed, the treatment element 10 reciprocates at a constant cycle, and this is the tapping operation of the treatment element 10. Further, when the motor 12 is rotated while changing its rotation speed, the treatment element 10 reciprocates at an irregular cycle, and this is the acupressure operation of the treatment element 10.

  As described above, the massage operation of the treatment element 10 is performed by driving the motor 11, and the tapping operation and the acupressure operation of the treatment element 10 are performed by driving the motor 12. By simultaneously driving the motors 11 and 12, the massage operation and the tapping operation are performed. The operation or the kneading operation and the acupressure operation are combined and performed. Of course, each operation can be performed independently.

  Such a massage mechanism 6 is attached to a lift 28 as shown in FIG. 1, and rollers 28 a are provided on both ends of the lift 28. The roller 28a is supported so as to be able to roll on a guide rail 29. A nut (not shown) is provided on the elevating table 28, and a screw bar 30 provided in parallel with the guide rail 29 is screwed to the nut. The upper and lower ends of the screw rod 30 are pivotally supported, and the lower end is connected to an output shaft of a motor (not shown) provided at a lower portion of the backrest portion 3. Therefore, when the screw rod 30 is rotated by the driving of the motor, the elevator 28 having the nut is restricted from rotating integrally with the screw rod 30 because the roller 28a is engaged with the guide rail 29. Then, the nut and the screw rod 30 rotate relatively, and the elevating table 28 and the massage mechanism 6 move up and down. With such a configuration, the massage mechanism 6 is moved up and down in a state where the user rests the upper body on the backrest portion 3, thereby performing a rolling operation in which the treatment element 10 rolls up and down on the back of the user. be able to.

As a result, the air bag 50 contracts, and the holding portion 47 rotates upward (in a direction away from the forearm of the user) by the urging force of the urging means described above, and the air bags 73a and 73b rise with this. . In this way, the forearm of the user is pulled upward while being sandwiched by the air bags 72a, 72b and 73a, 73b, and so-called kneading is performed on the forearm of the user.

  After a lapse of a predetermined time from the start of evacuation of the air bladder 50, the control circuit 81 transmits a predetermined control signal to the drive circuit 54 to supply and exhaust air from each of the air bladders 72a, 72b, 73a, 73b. The operation of the device 9 is controlled (step S45). Thereby, the pressing force on the forearm of the user is released.

  Then, the control circuit 81 determines whether or not the end of the forearm massage is instructed by the user (step S46), and returns the process to step S42 when the end instruction is not received. If an end instruction has been received in step S46, the process ends.

  Therefore, unless the user receives an instruction to end the forearm massage from the user, the forearm massaging by the forearm massage machine 71 is repeatedly executed. The strength of the forearm massage can be adjusted by the user performing a predetermined operation input on an operation panel (not shown). The air supply time to each of the air bladders 50, 72a, 72b, 73a, 73b is set long, and when the massage intensity is weakened, the air supply time is set short. In order to adjust the massage strength, the length of the air supply time need not be adjusted, and the pressure of the air supplied to each of the air bags 50, 72a, 72b, 73a, 73b may be adjusted. The massage strength may be adjusted by adjusting the flow rate of air supplied to each of the air bladders 50, 72a, 72b, 73a, and 73b per unit time. .
