  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 6 shows an example of a chair type massage machine 12 equipped with the hand massager 1 of the present invention. The chair type massage machine 12 includes a backrest part 14, a seat part 15, an armrest part 13, and a footrest 16, and the hand massager 1 is mounted on the armrest part 13. The backrest 14 and the mount 16 are preferably provided with a treatment element for performing back and foot massage or an airbag, and further preferably provided with a reclining mechanism for raising and lowering the backrest 14.

  In the hand massager 1 of this embodiment, a U-shaped massage case 18 is mounted on the upper surface of a base 17 as shown in FIG.

  Inside the base 17, an air pump 19 for supplying air to the plurality of airbags 20 and 21 shown in FIG. 4B, an electromagnetic valve 36 for controlling air supply / exhaust, and a control circuit for controlling this (FIG. Etc.) are stored.

  In the U-shaped massage case 18, the arm holding part 3, the connection driving part 6, and the hand holding part 5 are arranged in this order. That is, the hand massager 1 of this example also has a function of massaging the arm 2.

  Here, the arm holding part 3 is for holding or massaging the arm 2 of the user, and is fixed so as not to move with respect to the base 17. Arm massage airbags 21a and 21b are disposed on the upper and lower wall surfaces of the arm holding portion 3, respectively.

  The hand holding unit 5 is for holding or massaging the user's hand 4 and is not fixed to the base 17 and is slidable back and forth along the longitudinal direction A. Hand massage airbags 21c and 21d are provided on the lower surface of the upper wall 5a and the upper surface of the lower wall 5b, respectively, and the airbag 21e (see FIG. 7) is provided between the lower surface of the lower wall 5b and the base 17. To FIG. 9).

  The arm holding part 3 and the hand holding part 5 are connected via a connection driving part 6 shown in FIGS. The connection driving unit 6 drives the arm holding unit 3 and the hand holding unit 5 relatively, and in this example, drives the arm holding unit 3 and the hand holding unit 5 in directions away from each other. The upper and lower connecting drive airbags 20a and 20b are provided. The upper and lower connecting drive airbags 20a and 20b are each formed in a bellows shape that can expand and contract in the longitudinal direction A, and both front and rear ends thereof are connected to the arm holding portion 3 and the hand holding portion 5, respectively.

  As shown in FIG. 4B, the arm massage airbags 21a and 21b, the hand massage airbags 21c and 21d, and the connection drive airbags 20a and 20b respectively include an air hose and an electromagnetic valve 36. And is connected to a common air pump 19.

  Here, in the present invention, as shown in FIGS. 1 to 3, in the hand holding portion 5, a plurality of (four in this example) finger partition walls 35 inserted between the fingers a to e are respectively provided. An example in the case of providing is shown. As shown in FIG. 1A, each finger partition wall 35 inserted between the fingers ae opens and closes the fingers ae around one end 35a facing the base side of each finger ae. In addition, on both side surfaces of the finger partition walls 35 facing the fingers a to e, respectively, a finger stretch airbag that performs expansion and contraction operations by supplying and exhausting air. 20f is arranged. 21 d in the figure is an air bag for hand massage that massages the palm of the hand 4.

  As shown in FIG. 1B, each finger stretch airbag 20 f disposed on both side surfaces of the finger partition wall 35 is connected to the air pump 19 via an air hose and an electromagnetic valve 36.

  When massaging fingers a to e, as shown in FIG. 2, each finger a to e is inserted between each finger partition wall 35, and air is simultaneously supplied to all finger stretching airbags 20f. As shown in FIG. 3, the fingers a to e are opened to stretch the joints of the fingers. Further, the fingers a to e can be stretched by controlling the electromagnetic valve 36 so that the respective airbags 20f for stretching the fingers are inflated in order or randomly.

  In addition, the wrist 7 can be stretched simultaneously with the stretching of the fingers a to e by the finger stretching airbag 20f of this example. In other words, the arm 2 is held by the arm holding unit 3, the hand 4 is held by the hand holding unit 5, and the fingers a to e are stretched by the expansion and contraction of the finger stretching airbag 20f, and simultaneously connected. By supplying and exhausting air to and from the coupling drive airbags 20a and 20b of the drive unit 6, a stretching operation (FIG. 9) for extending the joint of the wrist 7 described later can be performed simultaneously. Further, at this time, the arms 2 and the hands 4 can be massaged simultaneously by supplying and exhausting air to the arm massage airbags 21a and 21b and the hand massage airbags 21c and 21d.

  The stretching of the fingers a to e can be performed separately from the massage of the arm 2 and the hand 4 and the stretching of the joint of the wrist 7. That is, in the stretching of the fingers a to e, the operation is only to open the fingers a to e, so that the stretching operation of the fingers a to e can be performed independently without holding the arm 2 or the hand 4. .

  Thus, the stretch effect of improving blood flow and lymph flow by loosening the joints and muscles of the fingers a to e is obtained by performing the stretch massage by opening the fingers a to e with the airbag 20f for finger stretching. It becomes like this. In addition, the effect of improving the flexibility of the body can be obtained by widening the range of motion of the joints of the fingers a to e. In addition, by disposing the finger stretching airbag 20f on both sides of the finger partition wall 35, the turning operation of the finger partition wall 35 and the expansion / contraction operation of the finger stretching airbag 20f are combined, and the fingers a to e are combined. It is possible to perform a stretch massage of fingers a to e in which many acupuncture points are gathered more comfortably while giving a soft touch and elasticity moderately.

  Next, when performing normal massage of the hand 4 or the arm 2, as shown in FIGS. 7 and 8, the arm 2 is put in the arm holding part 3 and the hand 4 is put in the hand holding part 5, By supplying air to the hand massage airbags 21c and 21d and the arm massage airbags 21a and 21b, the arm 2 and the hand 4 are pressed to promote blood circulation and to obtain a normal massage effect to relieve stiffness.

  On the other hand, when performing stretch massage to stretch the wrist 7, as shown in FIG. 5, the air pressure was increased by supplying air to the hand massage airbags 21c, 21d and the arm massage airbags 21a, 21b. By shutting off air in the state, the arm 2 and the hand 4 are held so as not to move. In this state, by supplying air to the coupling driving airbags 20a and 20b, the bellows-shaped coupling driving airbags 20a and 20b are inflated, as shown in FIG. Is moved in a direction away from the arm holding portion 3 to perform a stretching operation for extending the joint of the wrist 7. At this time, it is also possible to perform stretch massage of each finger a to e by the finger stretch airbag 20f.

  Since the arm holding part 3 and the hand holding part 5 are connected to each other via the bellows-like connection driving airbags 20a and 20b, as shown in FIG. 5, the connection driving airbag 20a is connected. , 20b is repeatedly supplied and exhausted to perform a stretch massage in which the hand holding portion 5 slides and stretches the joint of the wrist 7, thereby loosening the joint and muscles of the wrist 7 to thereby improve blood flow and lymph. In addition to the stretch effect that improves the flow, the effect of improving the flexibility by widening the range of motion of the joint of the wrist 7 is also obtained. Furthermore, the stretch effect of each finger ae by the finger stretch airbag 20f is performed together, and a further stretch effect can be expected.

  Moreover, since the hand massager 1 of this example is mounted on the armrest 13 of the chair type massage machine 12, not only the massage around the arm 2 and the hand 4, but also the whole body massage that massages the back and legs, for example. Because it can be used together, you can expect a synergistic effect of massage. The same applies to the following embodiments.

  FIGS. 10 to 15 are other embodiments of the hand massager 1 according to the first embodiment, and a first for rotating the hand holding part 5 around the axis 8 in the longitudinal direction A of the arm 2 with respect to the arm holding part 3. An example of the rotation drive unit 9 is shown. Other configurations are the same as those of the embodiment of FIGS. 1 to 3, and corresponding portions are denoted by the same reference numerals and detailed description thereof is omitted. In this example, upper and lower hand massage airbags 21c and 21d are disposed in the upper half portion of the space between the lower wall 5b and the upper wall 5a of the hand holding portion 5, and the first rotation driving portion is disposed in the lower half portion. 9 is disposed. Here, in the first rotation drive unit 9, the lower plate 22, the intermediate plate 23, and the upper plate 24 are sequentially stacked, the lower plate 22 is fixed to the upper surface of the lower wall 5 b of the hand holding unit 5, and the lower plate 22. One end 22a of the intermediate plate 23 and one end 23a of the intermediate plate 23 are rotatably connected via a rotating portion 25a, and the other end 23b of the intermediate plate 23 and the other end 24b of the upper plate 24 are rotated. It is rotatably connected via the moving part 25b. Further, a rotational drive airbag 20c is interposed between the other side end 22b of the lower plate 22 and the other side end 23b of the intermediate plate 23, and one side end 23b of the intermediate plate 23 and one side end 24a of the upper plate 24. A rotational drive airbag 20d is interposed between the two. The lower hand massage airbag 21 d is disposed on the upper surface of the upper plate 24.

  The two rotational driving airbags 20c and 20d for twisting the wrist are connected to a common air pump 19 via an air hose and an electromagnetic valve 36 as shown in FIG.

  Next, when performing stretch massage by twisting the wrist 7, the hand 4 is put into the hand holding portion 5 as shown in FIG. 7, and air is applied to the hand massage airbags 21c and 21d and the arm massage airbags 21a and 21b. The upper and lower sides of the arm 2 are held by the arm massage airbags 21a and 21b, and the palm of the hand 4 and the back of the hand 4 are vertically hand massaged. It is held by the airbags 21c and 21d, and the arm 2 and the hand 4 are not moved. In this state, when air is supplied only to one of the rotational drive airbags 20d, the upper plate 24 on which the hand 4 is placed rotates counterclockwise around the rotating portion 25b as shown in FIG. Then, after the air is exhausted, when the air is supplied only to the other rotational drive airbag 20c, the upper plate 24 on which the hand 4 is placed turns the rotating portion 25a as shown in FIG. Rotates clockwise around the fulcrum. Thus, the stretch operation of twisting the wrist 7 is performed by repeatedly supplying and exhausting air to and from the two rotational driving airbags 20c and 20d. FIGS. 13 to 15 specifically show the twisting operation, FIG. 13 shows a state in which the hand 4 is put in the hand holding portion 5, FIG. 14 shows a case where the hand is twisted counterclockwise, and FIG. The case where it is twisted around is shown. At this time, it is also possible to perform stretch massage of each finger a to e by the finger stretch airbag 20f.

  Thus, by performing a stretch massage that twists the joint of the wrist 7 by the rotational drive airbags 20c and 20d for twisting the wrist, the joint 7 and muscles of the wrist 7 are loosened to improve the blood flow and lymph flow. can get. In addition, the flexibility of the body can be improved by widening the range of motion of the joint of the wrist 7. In addition, by forming the coupling driving airbags 20a and 20b in a bellows shape, the hand holding portion 5 can be turned well, and the wrist 7 can be twisted more effectively. Furthermore, the stretch effect of each finger ae by the finger stretch airbag 20f is performed together, and a further stretch effect can be expected.

  16 to 18 show still another embodiment of the hand massager 1 described above, and the hand holding unit 5 is rotated around the axis B perpendicular to the longitudinal direction A of the arm 2 with respect to the arm holding unit 3. An example of the second rotation drive unit 11 is shown.
