That is, this cross press massage is NO. 1 and NO. 3 7-second air supply → NO. 1 and NO. 3 for 5 seconds → NO. 2 and NO. 4 for 7 seconds → NO. 2 and NO. 4 and 5 second exhaust cycle is repeated.

  Note that NO. 1 and NO. Instead of expanding 3 simultaneously, it is also possible to provide a time difference in one expansion. For example, although not shown, the control unit 4 first determines NO. No. 1 with a delay of 3 seconds while inflating by supplying air to 1 over 7 seconds. 3 is supplied to inflate it. Then, NO. 1 and NO. 3 is exhausted and contracted, and then NO. No. 4 with 3 seconds delay while supplying and inflating 4 to 7 seconds. 3 is supplied to inflate it. Then, NO. 4 and NO. Exhaust from 2 and contract. That is, NO. 7 seconds air supply (supply to NO. 3 after 3 seconds) → 5 seconds exhaust → NO. No. 4 7 second air supply (after 3 seconds, supply to NO. 2) → 5 second exhaust cycle.

  In this case, the order of air supply may be reversed. That is, NO. No. 3 7 seconds air supply (after 3 seconds supply to NO.1) → 5 seconds exhaust → NO. 7 second air supply (supply to NO.4 after 3 seconds) → 5 second exhaust cycle is repeated.

  Although the front and back press massage of (c) is not shown in the figure, the control unit 4 first supplies air to the inner and outer third upper airbags 145a and 145b and inflates them to maintain the instep. . Then, as shown in FIG. 1 and NO. 4 is simultaneously supplied with air and inflated (FIG. 9A). 1 and NO. 4 is pressed from the front by expansion. Then, NO. 1 and NO. 4 is exhausted and contracted to release the pressure from the front of the leg (FIG. 9B). Thereafter, the control unit 4 determines NO. 2 and NO. 3 is simultaneously supplied with air and inflated (FIG. 9C), the leg is pressed from the rear, and then NO. 2 and NO. The cycle of exhausting from 3 and contracting to release the pressure from the rear of the leg (FIG. 9D) is repeated. Then, when finishing the front / rear press massage, the air is exhausted and contracted from the inner and outer third airbags 145a and 145b. That is, NO. 1 and NO. 4 7 seconds air supply → 3 seconds exhaust → NO. 2 and NO. Repeat the cycle of 3 7-second air supply → 3 second exhaust. Thus, this massage machine is controlled by the control unit 4 with the first air treatment unit (NO.1: right first leg airbag 37, NO.4: left first leg airbag 36) and the second. Each airbag is inflated and contracted in the air treatment section (NO.2: right second leg airbag 35R, NO.3: left second leg airbag 35L), and the legs of the user are moved forward. The air massage which presses from the back or from back can be performed. Therefore, the entire leg can be massaged sufficiently.

  It is also possible to combine full-tightening massage in the middle of front and back press massage. That is, NO. 1 and NO. 4 is supplied and expanded at the same time, and is not exhausted. 2 and NO. 3 is provided with a process of inflating by supplying air at the same time, and pressing the leg from all sides. 1-NO. 4 is exhausted, and this time NO. 2 and NO. 3 is supplied and expanded at the same time, and NO. 1 and NO. 4 is supplied and expanded at the same time. 1-NO. The cycle of exhausting all 4 is repeated. Note that the air supply time is 7 seconds and the exhaust time is 3 seconds. That is, NO. 1 and NO. 4 for 7 seconds (NO.2 and NO.3 supply after 3 seconds) → 3 seconds exhaust → NO. 2 and NO. No. 3 7 second air supply (NO.1 and NO.4 air supply after 3 seconds) → 3 second exhaust cycle is repeated.

  By the way, in this front and rear press massage, the inner and outer third inflatable airbags 145a and 145b are operated. As shown in FIG. 10, the leg can be moved in the front-rear direction, that is, in the horizontal direction while restricting the movement of the foot up and down. At this time, the convex portion 146 provided on the sole receiving portion 144 can effectively perform massage of the sole, which is said to have many points to heal fatigue. Moreover, if the pressing force of the inner and outer third airbags 145a and 145b is adjusted as appropriate, the downward force on the foot changes, so the relative pressing force between the sole and the convex portion 146 changes. In particular, the amount of stimulation to the sole by the convex portion 146 can be changed.

  That is, as shown in FIG. 10A, when the right first leg airbag 37 (NO.1) and the left first leg airbag 36 (NO.4) are simultaneously supplied and inflated, Is moved backward (arrow direction). Thereafter, the air is exhausted from the right first leg airbag 37 (NO.1) and the left first leg airbag 36 (NO.4), and the right second leg airbag 35R (NO.2) and When air is supplied to the left second leg airbag 35L (NO. 3) and inflated at the same time, the leg is pushed forward (in the direction of the arrow) and moved, as shown in FIG. Since the foot can be forcibly moved back and forth in this way, the foot massage can be automatically performed by the convex portion 146 provided in the foot receiving portion 144. In addition, the code | symbol M has shown the to-be-treated person's leg position in FIG. 10, and shows the leg by sectional view. Thus, in this massage machine, the control unit 4 causes the first air treatment unit (NO.1: right first leg airbag 37, NO.4: left first leg airbag 36) and second. In the air treatment section (NO.2: right second leg airbag 35R, NO.3: left second leg airbag 35L), the airbag of each user is alternately expanded and contracted. The foot massage by the convex part 146 can be performed by sliding in the front-rear direction.

  Furthermore, in this massage machine, the control unit 4 causes the first air treatment unit (NO. 1: right first leg airbag 37, NO. 4: left first leg airbag 36) and the second air. Pressing force of the inner and outer third airbags 145a and 145b during the air massage by the treatment unit (NO.2: right second leg airbag 35R, NO.3: left second leg airbag 35L) Can be changed to selectively change the movement direction and / or movement restriction force of the user's foot. Therefore, the user can perform leg massage or sole massage according to his / her preference.

  By the way, when performing foot massage by forcibly moving the legs back and forth within the leg receiving portion 14a, the right first leg airbag 37 (NO.1) and the left first leg airbag 36 (NO. When exhausting 4), the outer airbags 37b and 36b may be exhausted.

  Further, in the present embodiment, the convex portion 146 is a fixed projection, but it can also be configured so as to be able to appear and retract up and down. In this case, the actuator that moves the convex portion 146 up and down is naturally managed by the control unit 4. And the amount of stimulation to the sole can be changed by controlling the amount of protrusion of the convex part 146.

  In the rotary massage (d), as shown in FIG. The air is supplied to 1 and inflated, and the leg is pressed from the right front side (FIG. 11A). After 2 seconds, NO. The air is supplied to 2 and inflated to apply pressure from the right rear to the leg (FIG. 11 (b)). Then, after 2 seconds, NO. The air is supplied to 3 and inflated to further apply pressure from the left rear to the leg (FIG. 11 (c)). In addition, NO. No. 4 is inflated by applying air pressure to the leg from the left front, while NO. 1 is exhausted and contracted (FIG. 11D). Thereafter, as shown in FIGS. 11 (e) and 11 (f), NO. 2, NO. 3 is exhausted and contracted, and finally NO. 4 is exhausted and contracted to release the pressure on the legs (FIG. 11 (g)). As shown in the figure, in the rotary massage that repeats such a cycle, the pressure on the leg is clockwise in a plan view, but it may be counterclockwise or may be rotated in the left and right leg receiving portions 14a. I do not care. In this rotational massage, more effective massage can be realized if the inner and outer third upper airbags 145a and 145b are operated to hold the upper part of the foot so that the foot (leg) does not escape. .

  That is, in this rotary massage, NO. 1 supply → 2 seconds later NO. 2 air supply → 2 seconds later NO. 3 supply → 2 seconds later NO. 4 air supply (NO.1 exhaust at the same time) → After 2 seconds, NO. 2 exhaust-> 2 seconds later, NO. 3 exhaust → NO. The cycle of exhaust 4 is repeated.

  As one form of this rotary massage, NO. 4 and NO. 1 and after 1.5 seconds, NO. 4 exhaust → NO. 0.5 seconds later. 2 air supply → 2 seconds later NO. 3 air supply (NO.1 exhaust at the same time) → After 2 seconds, NO. 4 supply → NO. 1 air supply, and also NO. It is also possible to repeat the cycle of exhaust 4.

  As shown in FIG. 12, the control unit 4 first performs NO. 1 and NO. 2 is simultaneously supplied over 5 seconds to inflate and push the leg to the left (FIG. 12 (a)). Then over 3 seconds NO. 1 and NO. 2 is exhausted and contracted (FIG. 12B). Next, the control part 4 is NO. 3 and NO. 4 is simultaneously supplied over 5 seconds to inflate, and this time the leg is pushed rightward (FIG. 12 (c)). Then over 3 seconds NO. 3 and NO. 4 is exhausted and contracted (FIG. 12D). That is, NO .. 1 and NO. 2 5 seconds supply → 3 seconds exhaust → NO. 3 and NO. The cycle of 4 5 second air supply → 3 second exhaust is repeated.

  In addition, it is possible to combine full-tightening massage for a short time while shaking left and right. That is, the control part 4 is NO. 1 and NO. 2 is simultaneously supplied over 5 seconds to inflate, push the leg to the left, 3 seconds later, NO. 3 and NO. 4 is inflated by simultaneously supplying air over 5 seconds, and the leg is pressed from all sides for 2 seconds. And NO. 1 and NO. 2 is exhausted and contracted, and after 3 seconds, NO. 3 and NO. The cycle of exhausting 4 and contracting is repeated. That is, NO. 1 and NO. 2 5 seconds supply → 3 seconds later NO. 3 and NO. 4 5 seconds supply → 2 seconds later NO. 1 and NO. 2 exhaust-> 3 seconds later NO. 3 and NO. The cycle of exhausting 4 is repeated.

  As shown in FIG. 13, the whole pulse massage of (f) causes the control unit 4 to perform substantially the same operation as in the case of the full tightening massage, but the air supply time and the exhaust time are considerably shorter than the full tightening massage. Yes. That is, NO. 1-NO. 4 is supplied and expanded in 2 seconds, and the legs are tightened from four directions (FIG. 13A). 1-NO. All of 4 are exhausted in 1 second and contracted to immediately release the tightening of the legs (FIG. 13B). In other words, tightening massage is NO. 1-NO. 4 2-second air supply → NO. 1-NO. This is a repetition of the 1 second exhaust cycle of No. 4, and a leg massage in which an appropriate tightening force is continuously generated like a pulse.

  The partial pulse massage of (g) is NO. 1-NO. One of the four airbags 4 sequentially performs a pulse operation of inflating for a short time and pressing the leg. For example, the control unit 4 first determines NO. 2-NO. 4 is inflated by supplying air. For 1, a pulse operation is performed in which air is supplied for 1 second, inflated, and immediately exhausted and contracted (FIG. 14A). Then, when this pulse operation is performed 10 times, all the gas is exhausted and contracted over 3 seconds (FIG. 14B). And the control part 4 is NO. 2, NO. 3, NO. The pulse operation is performed in the order of four. As described above, in the partial pulse massage, the pulsing airbag sequentially moves in the circumferential direction.

  Although not shown, as an example of pulse massage, NO. 1 and NO. 4 and the leg is pressed and held from the front. 2 and NO. Then, a pulse operation is performed in which the air is supplied and expanded for 3 seconds and exhausted in 1 second and immediately contracted. Alternatively, NO. 1 and NO. No. 4 in the state where the air was supplied to 4 and the leg was pressed and held from the front. 2 and NO. It is also possible to alternately perform a pulse operation in which 3 is supplied for 1 second to be expanded and exhausted in 1 second and immediately contracted. Note that the 1-second air supply 1-second exhaust in the pulse operation may be replaced with the 2-second air supply 2 seconds exhaust.

  The specific example of the leg massage has been described above. In this embodiment, four sets of airbags including left and right first leg airbags 36 and 37 and left and right second leg airbags 35L and 35R are provided in each leg receiving portion 14a. Because the treatment part is provided and the legs of the user can be pressed from all sides, it is possible to massage up to the shin part, which is the front side of the leg, which could not be massaged normally, realizing an effective massage to heal leg fatigue etc. it can. In addition, since one of the right and left first leg airbags 36 and 37 can be used for holding the leg, the leg is firmly held while massaging the shin portion on the front side of the leg. Can be maintained, and the massage effect of the calf portion is further improved.

  By the way, in this embodiment, the airbag that maintains the inflated state is the one of the left and right first leg airbags 36 and 37 that has relatively no muscles in the shin. That is, control is performed so as to maintain the inflated state of the right first leg airbag 37 (NO.1) for the left leg and the left first leg airbag 36 (NO.4) for the right leg. did. And about the other leg airbag 30, the expansion / contraction operation | movement can be arbitrarily controlled. Therefore, when the leg is held, the first air treatment unit that does not perform the massage by expansion and contraction presses the inner part of the shin that is relatively unmuscle, and thus the good massage feeling is impaired. There is no fear.

  At this time, the left first leg airbag 36 (NO.4) is used for the left leg, and the right first leg airbag 37 (NO.1) is used for the right leg. The outer portion of the shin is massaged, and the outer airbag 36b of the left first leg airbag 36 for the left leg and the outer airbag 37b of the right first leg airbag 37 for the right leg are respectively inflated. By maintaining the state, the expansion / contraction start position of the inner airbag 36a for the left leg and the inner airbag 37a for the right leg are defined. That is, the inner airbags 36a and 37a are defined at appropriate positions in the depth direction (the direction of the inner surface 141a) in the leg receiving portion 14a.

  In addition, the present massage machine can fill the half-cylindrical space of the leg receiving portion 14 a in the leg mounting portion 14 with the leg airbag 30. That is, the user can place the leg outside the leg receiving portion 14a in a natural state rather than accommodating the leg in the leg receiving portion 14a.

  That is, when the left and right first leg airbags 36 and 37 and the left and right second leg airbags 35L and 35R are all supplied with a maximum air pressure, as shown in FIG. The leading ends of the inner air bags 36a and 37a of 36 and 37 are brought into contact with each other. The user can place his / her legs on the inner airbags 36a and 37a of the left and right first leg airbags 36 and 37, respectively. At this time, the legs are held from the left and right by the outer airbags 36b and 37b of the left and right first leg airbags 36 and 37, respectively.

  The left and right second leg airbags 35L, 35R and the outer airbags 36b, 37b of the left and right first leg airbags 36, 37 are supplied with a substantially maximum value, while the left and right first leg airbags 36, If air is not supplied to the inner airbags 36a and 37a of 37 or a small amount of air is supplied, the outer airbags of the left and right first leg airbags 36 and 37 are shown in FIG. The tip ends of 36b and 37b come into contact with each other. Therefore, the user can place his / her legs on the outer airbags 36b and 37b of the left and right first leg airbags 36 and 37. In this case, the leg placement surface can be made wider than the example shown in FIG.

  Thus, if the space of the half cylindrical body of the leg receiving part 14a is filled with the leg airbag 30, for example, if the leg mounting part 14 is rotated upward, the leg is normally moved. Although it will be in the state mounted in the back part surface 141a of the leg receiving part 14a, in the example shown in FIG. 15, it will be possible to mount a leg in an upper position, and it is effective when the slackness of a leg is eliminated. It becomes.

  In addition, when the leg rest 14 is in a normal position, that is, when the leg support 14a is positioned in a substantially vertical direction, a part of the leg is in the leg support 14a, and thus the leg is unnatural and protrudes forward. It does not become a proper posture.

  By the way, in the present embodiment, the left inner airbag 36a and the left outer airbag 36b of the left first leg airbag 36 attached to the central standing wall 143 have the base end portions substantially the same at the central standing wall 143. The right inner airbag 37a and the right outer airbag 37b of the right first leg airbag 37 attached to the side wall 142 are also connected to the side wall 142 at the base end portions of the right inner airbag 37a and the right outer airbag 37b. It was. Therefore, the connecting position between the left inner airbag 36a and the left outer airbag 36b and the connecting position between the right inner airbag 37a and the right outer airbag 37b are separated from each other, and all the leg airbags 30 are substantially max. As shown in FIG. 16, it is possible to fill the entire leg receiving portion 14a. In this case, the front open surface is as if closed. Therefore, when the leg rest part 14 is rotated upward, the user can place the leg at a position considerably above the upper body.
