  However, in the case where the arm of the user is held on the armrest as described above and the treatment is performed by expanding and contracting the air bag with compressed air from the upper surface or the side surface, both arms are fixed when performing arm massage. Even when sudden physical condition or abnormal operation of the device occurs, there is a problem that both the arms are fixed and the device cannot be stopped or evacuated and exposed to danger.

  The present invention has been invented in view of the above-described conventional problems, and it is an object of the present invention to provide a chair-type massage machine that can stop or retreat equipment even in an emergency due to abnormal operation or poor physical condition.

In order to solve the above problems, a chair-type massage machine according to claim 1 of the present invention has a seat surface, a backrest, and an armrest, and presses and massages an arm massage part that presses an arm held by the arm holding part on both sides. In the chair type massage machine on the armrest, the upper limit pressure that can easily remove the arm from the arm massage part is the critical pressure that allows arm escape, and the arm massage part of the left and right armrests has the pressure to press the arm When the arm is pressed with a strong compression force, the other arm's compression force is set to medium or no. In the massage, when the pressure to press the arm of each massage part is changed from nothing to strong, and when changing from strong to medium and then nothing, arm massage on the left and right sides is always performed. In addition to pressure on both sides of the arm, the pressure constantly compressing the arms of one of the arm massage unit and controlling so that the arm escape possible critical pressure or less pressure. By configuring as described above, even one that massages by pressing with the arm massage part while holding both arms, one arm of both arms can always be detached from the arm massage part, abnormal operation and poor physical condition Even in the event of an emergency, the device can be stopped or evacuated.

In addition, the chair type massage machine according to claim 2 has a seat surface, a backrest, and an armrest, and has arm massage parts that massage the arm held by the arm holding part on both armrests. The chair that controls to change the pressure of both arms so that the pressure of one of the arms can be removed from the arm massager when both arms are massaged at the same time It is a type massage machine, the upper limit pressure that can easily detach the arm from the arm massage part is the critical pressure that can escape the arm, the arm massage part of the left and right armrests has no compression force to press the arm, Repeat the cycle of lower than the critical pressure for arm escape and higher than the critical pressure for arm escape, and when the arm is compressed with a strong compression force, the compression force of the other arm should be medium or no. Yes, this In the massage, when the pressure that presses the arm of each massage part is changed from nothing to strong through the middle, and when changing from strong to nothing, the arm massage parts of the armrests on both the left and right sides should always be used. While pressing, it controls so that the pressure which always presses the arm of one arm massage part may become the pressure below the critical pressure which can escape arm. By configuring as described above, even one that massages by pressing with the arm massage part while holding both arms, one arm of both arms can always be detached from the arm massage part, abnormal operation and poor physical condition Even in the event of an emergency, the device can be stopped or evacuated. In addition, since the compression force to press the arm of the arm massage part is repeated without, medium, and strong , in this case, it is possible to massage the arm properly by repeating the cycle of no compression, medium, and strong, Moreover, even if one arm of both arms is pressed with a strong pressing force, at least one arm can be detached from the arm massage portion by setting the other arm to a medium or no pressing force.

Further, the chair type massage machine according to claim 3 has a seat surface, a backrest, and an armrest, and has arm massage portions for pressing and massaging the arm held by the arm holding portion on both armrests, The chair that controls to change the pressure of both arms so that the pressure of one of the arms can be removed from the arm massager when both arms are massaged at the same time It is a type massage machine, the upper limit pressure that can easily detach the arm from the arm massage part is the critical pressure that can escape the arm, the arm massage part of the left and right armrests has no compression force to press the arm, Repeat the cycle of strength higher than the critical pressure for arm escape and lower than critical pressure for arm escape, and when pressing the arm with a strong compression force, the compression force of the other arm should be medium or no. Yes, this In massage, when changing the pressure that presses the arm of each massage part from nothing to strong, and when changing from strong to inside through no, always move the arms on both sides with the arm massage parts on the left and right sides. While pressing, it controls so that the pressure which always presses the arm of one arm massage part may become the pressure below the critical pressure which can escape arm. By configuring as described above, even one that massages by pressing with the arm massage part while holding both arms, one arm of both arms can always be detached from the arm massage part, abnormal operation and poor physical condition Even in the event of an emergency, the device can be stopped or evacuated. In addition, because the compression force to press the arm of the arm massage part is no, strong, and the middle cycle is repeated , in this case, the appropriate force massage can be done by repeating the compression force no, strong, and the middle cycle, Moreover, even if one arm of both arms is pressed with a strong pressing force, at least one arm can be detached from the arm massage portion by setting the other arm to a medium or no pressing force.

  It is also preferable that the arm to be treated is pre-compressed and then once released and compressed again. In this case, pre-compression has the effect of notifying the user that massage of the arm is started and the effect of getting used to the treatment. It has the effect of making it easier to adjust to the user's desired strength by giving the opportunity to adjust the force of compression to massage.

  It is also preferable that the arm which has been subjected to the pressure treatment is released once and then the post-compression is performed again. This has the effect of informing the user that the treatment of the arm has been completed, and can also provide a cool-down effect of the treatment operation.

  Since the present invention is configured as described, even if the arm massage part is pressed and massaged with both arms held, one arm of both arms can always be detached from the arm massage part, causing abnormal operation Even when an emergency occurs due to poor physical condition, the device can be stopped or evacuated to ensure the safety of the user.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. As shown in FIG. 1, the chair 1 is mainly composed of a backrest 2, a seat surface 3, left and right armrests 4, and an ottoman 5, and the upper surface of the left and right armrests 4 can be pivoted up and down to be opened and closed. A cover piece 6 is provided. The cover piece 6 is supported so as to be rotatable around a fulcrum in front of the armrest 4, and the cover piece 6 is opened and closed with the rear part up and down around the front part. Cover piece 6 is a state in which the overlapped state on the upper surface of the armrest 4 is closed, for the armrest 4 is a state of being rotated to a predetermined angle upwardly as shown in FIG. 1 and FIG. 2 is a state in which the open. As described above, the arm holding portion is configured by providing the cover piece 6 on the armrest 4 so that the arm can be held between the cover piece 6 and the upper surface of the armrest 4 with the cover piece 6 open. It has become.

  Massage means 7 and 8 are provided on the lower surface of the cover piece 6 and the upper surface of the armrest 4, thereby constituting an arm massage portion. In the case of this example, the massage means 7 and 8 are inflatable and contractible air bags, and compressed air is supplied from the air supply means 11 through the air supply pipes 9 and 10. This air supply means 11 is controlled by the control means so that compressed air can be supplied to the massage means 7 and 8 of the left and right armrests 4 at different arbitrary timings. In the case of this example, the massage means 7 and 8 are air bags that are inflated by compressed air and pressurize the human body. However, as the massage means 7 and 8, a treatment body with protrusions is placed, and a cover piece is formed using a motor. A system in which the human body 6 is moved up and down to press the human body may be used. In the following example, an example of an air bag that is compressed by compressed air will be described.

Put the arm between the upper surface of the armrest 4 and the cover piece 6 with the cover pieces 6 of the left and right armrests 4 open, and apply compressed force by supplying compressed air to the air bags of the massage means 7 and 8. Massage is performed, and at this time, control is performed to change the compression force of both arms so that the compression force of one of the arms becomes a pressure that allows the arm to be detached from the arm holding portion. That is, in the time chart as shown in FIG. 3, the pressure is applied to the arms with the air bags of the massage means 7 and 8 of the left and right armrests 4. In FIG. 3, the horizontal axis is time, and the vertical axis is air pressure (the pressure for pressing the arm is equal to the air pressure of the air bag), and the arm can be massaged by alternately applying a pressing force with the left and right armrests 4. . When the upper limit pressure at which the arm can be easily detached from the arm massage part is set to a critical pressure at which the arm can escape (for example, 9807 Pa (0.1 kgf / cm 2)), as shown in FIG. In the arm massage part, a state where the pressure is higher than the critical pressure at which the arm can escape is repeated, and a state where the arm pressure is set below the critical pressure at which the arm can escape is repeated. In the left and right armrests 4, the phase is reversed when applying a pressing force as described above, and when the pressing force is applied to one arm, the pressing force is not applied to the other arm. As a result, even if massage is performed with both arms placed on the left and right armrests 4, either arm is only under pressure that is below the critical pressure at which it can escape, and one arm can be held in the event of poor physical condition or abnormal device operation. It can be removed, and the device can be stopped or evacuated.

  In addition, when the treatment starts (pressurizes), a means for measuring the pressure of the compressed air is attached, and the other pressurization is performed at the timing when the pressure of the air bag whose compression is stopped reaches the pressure at which the arm can escape. It may be started, or the time from when the compression is stopped until the arm escape pressure is reached is measured in advance, and pressurization of the air bag may be started after the time has elapsed.

In addition, when treating with the time chart of FIG. 3, the pressure of the arm which is not treated is made into zero (0) as a reference example . In this case, since one of the arms is not pressed at all, the arm can be easily pulled out.

  When treating with the time chart shown in FIG. 4, the compression force when massaging both arms is zero (0), medium (slightly lower than the critical pressure for arm escape), and strong (higher than the critical pressure for arm escape). This cycle is repeated. When one arm is pressed with a strong pressing force, the pressing force of the other arm is medium or nothing. In this way, the arm can be massaged effectively by applying a pressing force in the cycle of none, medium and strong. In addition, when one arm is compressed with a strong compression force, one arm can be detached because the compression force of the other arm is medium or nothing.

  When treating with the time chart shown in FIG. 5, the compression force when massaging both arms is zero (0), strong (higher than the critical pressure for arm escape), and medium (lower than the critical pressure for arm escape). The cycle is repeated. When one arm is pressed with a strong pressing force, the pressing force of the other arm is medium or nothing. In this way, the arm can be effectively massaged by applying a pressing force with no, strong and medium cycles. In addition, when one arm is compressed with a strong compression force, one arm can be detached because the compression force of the other arm is medium or nothing.

Also, in the reference example shown in FIG. 6, when one arm is pressurized to a pressure higher than the arm escapeable critical pressure, the compression force of the other arm is made lower than the arm escape critical pressure. Both arms are pressurized above the critical pressure at which both arms can escape. Even if both arms are pressurized above the critical pressure at which the arm can escape, the arms can be pulled out with a slight delay for a short time. In this case, it can be realized by simply controlling the pressurizing time without performing control for keeping the arm escaped below the critical pressure for a certain period of time.

In the present invention, when performing massage of both arms, one arm is set to a pressure higher than the critical pressure at which the arm can escape, but the other arm is set to a pressure lower than the critical pressure at which the arm can escape, so that the arm can come out. . In this case, when both arms are pressed and massaged, treatment may be performed as shown in the time chart of FIG. When the arm is treated, the arm to be treated is temporarily compressed, and then the compression is temporarily stopped (referred to as a pre-compression operation), and compression for massage is performed again. Such initial compression has the effect of informing the user that massage of the arm starts and the strength to treat, and confirms the strength of massage with the initial compression and stops temporarily. It has the effect of giving the opportunity to adjust the force of pressure to massage using the period.

  Alternatively, treatment may be performed as shown in the time chart of FIG. In this case, after either one of the arms is treated, the compression is temporarily stopped and the compression is again performed to stop the compression (referred to as a post-compression operation). By performing the post-pressing operation, there is an effect of notifying the user that the arm treatment is completed, and a cool-down effect of the treatment operation can be obtained.

  Alternatively, treatment may be performed as shown in the time chart of FIG. In this case, the pre-compression operation and the post-compression operation are performed before and after the one-arm massage operation.

  Moreover, it is preferable that the compression force of the above-described pre-compression operation or post-compression operation is set to a critical pressure at which the arm can escape or below the pressure. In this case, the user can easily remove the arm even if the user tries to remove the arm at the timing when the user presses the left and right simultaneously.

  In addition, it is desirable that the compression time of the pre-compression operation or the post-compression operation is a short time (about 2 seconds or less). In this case as well, even if the user tries to pull out the arm at the time when the user presses the left and right at the same time, the arm can be easily pulled out with a slight delay.

  It is also preferable to simultaneously perform the compression of the pre-compression operation of one arm and the post-compression operation of the other arm. In this case, since the arms to be treated are switched after pressing both arms at the same time, a continuous feeling can be obtained in the treatment. As described above, when the pressure of the pre-compression operation of one arm and the post-compression operation of the other arm are simultaneously performed, it is desirable that at least one of the pressures is equal to or lower than a critical pressure at which the arm can escape.

  Note that the pre-compression operation or the post-compression operation as described above may be performed a plurality of times.

  Moreover, it is also preferable to perform a pressure operation on both arms immediately after the start of the arm massage, and then remove the air in the air bag that compresses both arms, and then massage as described above after releasing the pressure. In this way, the massage pressure can be recognized by pressing both arms once immediately after the start of the massage, and can be changed to the user's favorite massage strength at the start of the massage.

  It is also desirable to repeat the massage operation for a certain period after the arm massage is started, and to perform the massage for the normal compression time after a certain period. In this way, by performing massage with a compression time shorter than usual for a certain period of time, it is possible to recognize the strength of the compression during the massage more reliably, so that the user can be sure of himself at the first stage of the massage. You can get an opportunity to change the massage strength to suit your needs.
