Description

  The present invention relates to a massage machine in which a plurality of airbags that press the arm of a user placed on an armrest portion according to the air supply amount are arranged so as to correspond to different positions of the arm.

  Conventionally, there are various types of chair-type massage machines having a seat, a backrest, and an armrest. Among these, massage is performed by pressing the arm of the user placed on the armrest with an airbag. There is a massage machine for performing (see, for example, Patent Document 1 and Patent Document 2). In this conventional massage machine, the air is supplied to the air bag in an amount determined by time control or the like.

By the way, when the user is seated in a natural state and the arm is placed on the armrest, the length of the arm generally becomes longer according to the height of the user, so that the user who is tall The position of the airbag relative to the arm part differs between the user who is short and the height. For this reason, when a high-height user and a low-height user want to receive the same massage, the user needs to shift the position of the arm himself.

One end of the strength driving shaft 35 is pivotally supported by one side plate 21 a and the other end is pivotally supported by a worm wheel 77 in the gear box 34, and the pair of transmission gears are located near both ends of the strength driving shaft 35. 33 is formed, and the pair of left and right transmission gears 33 mesh with the pair of tooth portions 32a. Accordingly, when the motor of the strength / weakness drive unit 3 is driven to rotate forward and backward, the strength / weakness drive shaft 35 rotates via the gear box 34, and when the strength / weakness drive shaft 35 rotates, the transmission gear 33 rotates. As a result, the strength driving gear 32 and the width driving shaft 42 are rotated, whereby the treatment element arm 22 is rotated about the width driving axis 42 and the treatment element 20 provided at the distal end of the treatment element arm 22 is covered. The amount of protrusion to the user M side is changed. That is, as the treatment element arm 22 rotates, the treatment element 20 performs an arc motion (in the embodiment, an arc motion centered on the same axis as the width drive shaft 42) and moves in the vertical direction and the front-rear direction. The strength of the treatment element 20 with respect to the user M can be varied.

  The vertical drive unit 5 provided in the main block 21 is a vertical drive motor 51 as a drive source, and the output of the vertical drive motor 51 is transmitted to the vertical drive shaft 53 via the gear box 52, and the motor is driven forward or reverse. By doing so, the roller portion 54 and the pinion 55 provided on the vertical drive shaft 53 are rotated forward or reverse. The main block 21 meshes with a rack (not shown) provided on the rail 17 (see FIG. 1) in the backrest 12 with a pinion 55 provided on the roller 54, and the motor of the vertical drive unit 5 is operated as described above. By driving forward or reverse in this way, the pinion 55 meshed with the rack is rotated forward or reverse to move the main block 21 (that is, the treatment element 20 provided on the main block 21) upward or downward.

Are driven (interlocked) by a control unit (not shown) so that various massage operations by the treatment element 20 can be performed. Further, a backrest portion angle sensor and a footrest portion angle sensor for detecting the reclining angle of the backrest portion 12 by the above-mentioned backrest portion telescopic unit 15 and the tilt angle of the footrest portion 14 by the footrest portion telescopic unit 16 are provided. . Reference numeral 18 in the figure denotes an operating device. The control unit is connected to the sensors, the operation device 18, the strength drive unit 3, the width drive unit 4, and the vertical drive unit 5 and to the foot treatment unit 8 and the arm treatment unit 9 described later, Various massage operations can be performed by an operation input to the operation device 18.

  Moreover, in this embodiment, the pressing force detection means which measures the pressing force to the user M of the treatment element 20 is provided, and by this, the pressing force of the treatment element 20 to the treatment person M in the massage operation is provided. An example of the pressing force detection means will be described below, which is adjustable and capable of detecting the position of the shoulder of the seated user M.

  The pressing force detecting means is provided with an elastic body 71 in the gear box 34 of the strength driving unit 3 and detects the elastic displacement of the elastic body 71 to calculate the pressing force. The main body is composed of a displacement meter that detects elastic displacement.

  FIG. 5 shows the configuration of the transmission mechanism in the gear box 34. A rotary joint 72 is attached to the output shaft 31a of the strong and weak drive motor 31, and a worm shaft 73 is connected to the rotary joint 72 so as to be movable in the axial direction. The worm shaft 73 is provided with a bearing 74, and the bearing 74 is fitted in the outer ring bearing 75 fixed to the gear box 34 so as to be movable in the axial direction, whereby the worm shaft 73 is movable in the axial direction. And, it rotates through the rotary joint 72 by the rotation of the strong and weak drive motor 31. The worm shaft 73 has a worm gear 76 formed on the outer surface of the central portion in the axial direction, and a worm wheel 77 is engaged with the worm gear 76. The worm wheel 77 is rotatably supported by the gear box 34, and a strong and weak drive shaft 35 is concentrically provided at the center thereof. When the worm shaft 73 rotates, the worm wheel 77 and the strong and weak drive shaft 35 are connected. It rotates and gives the treatment element 20 a pressing force against the human body as described above.

  The worm shaft 73 is formed with a flange portion 78 on the outer surface near the end connected to the rotary joint 72, and the side surface of the flange portion 78 on the rotary joint 72 side serves as an elastic body 71. The spring is pressed at one end, and the other end of the coil spring is pressed against the wall surface of the gear box 34 in a state where the rotary joint 72 is inserted into the coil spring, so that the worm shaft 73 is separated from the strong and weak drive motor 31. It is spring-biased.

  When the treatment element 20 is pressed against the human body, the strength drive motor 31 rotates and the worm shaft 73 rotates via the rotary joint 72, and the portion of the worm wheel 77 meshing with the worm shaft 73 is the strength drive motor 31. Rotate to move away from. Normally, the worm shaft 73 is located farthest away from the strong and weak drive motor 31 by the urging force of the coil spring of the elastic body 71.

  When a pressing force is applied to the treatment element 20, the worm wheel 77 rotates in a direction to bring the portion engaged with the worm shaft 73 closer to the strength drive motor 31, whereby the worm shaft 73 is a coil spring of the elastic body 71. Therefore, the pressing force can be calculated from the displacement and the spring characteristic of the coil spring of the elastic body 71 by measuring the displacement. The displacement of the elastic body 71 can be indirectly measured by measuring the displacement of the worm shaft 73 with a displacement meter. In the present embodiment, as shown in FIG. 5, a flange-shaped gap detection body 79 is provided at the end of the worm shaft 73 opposite to the strong and weak drive motor 31, and a gap (distance) with the gap detection body 79 is provided. A gap sensor 70 (for example, a non-contact displacement meter such as an eddy current type) is attached to the gear box 34. Thereby, the pressing force can be calculated by measuring the displacement of the gap between the gap sensor 70 and the gap detector 79 of the worm shaft 73.

  The detection of the shoulder position by the pressing force detection means is performed, for example, when the main unit is moved to the upper limit position and the main body unit is lowered with the treatment element 20 protruding so that the treatment element 20 hits the shoulder. Since the treatment element 20 receives the pressing force from the shoulder, it may be determined that the shoulder 20 is detected when a predetermined pressing force is detected. The shoulder position may be detected by other determination methods.

  The foot rest part 14 is provided with a foot treatment part 8 in which two legs (calves) of a user who sits down on the seat part 11 can be inserted and positioned. Specifically, the foot treatment portion 8 is composed of a pair of concave grooves into which each foot is inserted and placed. The concave grooves are vertically and forwardly when the footrest portion 14 is suspended from the seat portion 11. It becomes the groove | channel which opens in this. The foot treatment portion 8 is provided with a foot airbag (not shown) that allows the right and left groove walls to expand and contract by supplying and discharging air. The air supply / exhaust pipe of the bag is connected to an air pump and an opening / closing valve, and the air pump and the opening / closing valve are driven by a control unit to perform massage on the foot by a foot airbag.

  Each armrest portion 13 is provided with an arm portion treatment portion 9 on which the arm portion of the user M seated on the seat portion 11 can be inserted and placed. Specifically, the arm treatment section 9 has side walls 91 provided upright on both the left and right sides of the upper surface of each armrest portion 13, and a groove 92 for inserting and mounting the arm portion between the both side walls 91 is formed. The airbag 93 is provided on the side wall 91 so that the airbag 93 inflates inward. Each of the airbags 93 is provided with an air pump and an on-off valve. The air pump and the on-off valve are driven by a control unit, and the feet are massaged by the expansion and contraction of the foot airbags 9 and 10. A plurality of airbags 93 are juxtaposed in the longitudinal direction of the armrest portion (that is, the longitudinal direction of the arm portion). In this embodiment, three airbags 93a1, 93a2, 93a3 are arranged in order from the end side on the inner side wall 91. At the same time, three airbags 93 b 1, 93 b 2, 93 b 3 are provided in order on the outer side wall 91 from the end side, and a total of six airbags 93 are provided in the arm treatment section 9 of the armrest 13 on one side. Although not shown, the air supply / exhaust pipe of the air bag 93 is connected to the air pump and the opening / closing valve, and the air pump and the opening / closing valve are driven by the control unit to massage the foot by the air bag. Each 93 is formed to be controllable. In the present embodiment, in the armrest 13 on one side, the airbag 93a1 and the airbag 93b1, the airbag 93a2 and the airbag 93b2, the airbag 93a3 and the airbag 93b3 perform the same expansion and contraction operation with the same opening / closing valve. It is what is said.

  The massage by this arm treatment part 9 is demonstrated.

  First, the user M sits on the seat 11 and leans against the backrest 12, and the shoulder position is determined by the above-described pressing force detecting means, and the height of the user M is estimated based on the shoulder position (this The pressure detection means is means for detecting height). For the estimation of height, for example, for a large number of subjects, the shoulder position is determined while sitting on this massage machine, and the correlation between the actual subject's height and the shoulder position is statistically determined, and for each height Although it is conceivable to store an average shoulder position as a database and refer to the value of this database, the height may be estimated by other methods. Then, the airbag 93 is controlled as shown in Table 1 based on the height. In Table 1, the air supply amount to each airbag is shown by the filling rate with respect to the estimated height.

  When the height of the user M is low, as shown in FIGS. 6 and 9, the hand of the user M does not reach the airbag 93a1 and the airbag 93b1 on the distal side of the arm treatment unit M, When the airbag 93a2 and the airbag 93b2 and only the airbag 93a3 and the airbag 93b3 on the root side come into contact with each other, and the height of the user M is high, as shown in FIGS. Since the hand reaches the airbag 93a1 and the airbag 93b1 on the end side of the arm treatment section M, all the airbags 93 come into contact with each other.

  Therefore, by controlling the airbag 93 as shown in Table 1, it is possible to perform a massage suitable for the height. Note that the control example shown in Table 1 is an example, and other controls may be used as a matter of course.

  According to the control example in Table 1, when the height of the user M is low, air is not supplied to the airbag 93a1 and the airbag 93b1 on the terminal side, so that unnecessary air supply can be eliminated. In addition, the arm of the high-height user M is generally thicker than the arm of the high-height user M, and the amount of air supply required to perform the same massage is smaller for the thick arm. The higher the height of the user M, the smaller the amount of air supplied to the airbag 93.

  In addition, in the state where the backrest part 12 is reclined as shown in FIG. 8, the position of the arm part in the arm part treatment part 9 is different from the state in which the same user M is not reclined, Correction for this is performed. For example, various corrections such as a correction of reducing the height by 10 cm for a reclining angle of 10 ° measured by the backrest angle sensor and determining the air supply amount based on the height after the correction can be considered. Thereby, even if it reclins and the position of the arm part deviates from the state which is not reclined, it becomes possible to correct | amend air supply amount and to perform an optimal massage.

  Although not shown, the air bag may be provided with means for detecting pressure, and the air supply amount to the air bag may be changed according to the detected pressure. This is based on the fact that if the pressure in the airbag is a predetermined pressure, the pressing force applied to the arm by the airbag becomes a predetermined value corresponding to the predetermined pressure. Since not only the length of the arm but also the thickness varies, it is difficult to give the same massage to all patients even if correction based on height is performed. By detecting the pressure of the bag and performing massage based on the detected pressure, it is possible to directly adjust the pressing force to the arm portion and to perform desired massage with higher accuracy.
