Description

Hand massager

Technical Field

The invention relates to a hand massager.

Technical problem

Massage of hands including fingers requires massage pressures (pressing forces) suitable for the palm, back and fingers, respectively. For example, it is known that the massage pressure applied to the palm is higher than the massage pressure applied to the back of the hand. However, in the massager of patent document 1, since the palm, the back of the hand, and the fingers are pressed by the expansion of the air bag, it is difficult to obtain a massage pressure suitable for each part.

The present invention aims to provide a massager capable of massaging a hand including a finger of a user with massage pressures respectively applied to a back of the hand, a palm, and the finger.

Technical scheme

One aspect of the present invention provides a hand massager including: a housing that defines an insertion space into which a hand including a finger is inserted, and includes a first main wall portion that faces a back of the hand inserted into the insertion space, and a second main wall portion that faces a palm of the hand inserted into the insertion space; a back-side airbag that is disposed on the first main wall portion and presses the back of the hand; a second-finger airbag formed in a tubular shape surrounding the fingers of the hand other than the thumb so as to press the fingers; an air supply source which is provided inside the housing, is connected to the dorsal-side airbag and the other-finger airbag so as to allow a fluid to pass therethrough, and supplies air to the dorsal-side airbag and the other-finger airbag so as to inflate and deflate the dorsal-side airbag and the other-finger airbag; a massage member disposed on the second main wall portion; and a driving mechanism, which is arranged in the shell and moves the massage component.

Since the back of the hand is pressed by the inflation of the air bag for the back of the hand, and the palm is pressed by the massage member, a higher massage pressure acts on the palm than on the back of the hand. The finger is pressed with the inflation of the air bag by the other finger. Thus, the hand including the fingers of the user can be massaged with the massage pressures suitable for the back of the hand, the palm, and the fingers, respectively.

By inserting the fingers other than the thumb into the other finger air bags, the position in the left-right direction of the palm is arranged at an appropriate position with respect to the air bag for the back side of the hand and the massage member. This improves the massage effect on the back and palm of the hand.

The drive mechanism is characterized in that the massage member is reciprocated in an arc shape so as to follow the edge of the palm on the wrist side.

According to this configuration, the massage member reciprocates in an arc along the edge of the palm, and thus a region with a high massage effect can be effectively massaged. It is easy to obtain a feeling like being massaged by a human hand.

Preferably, the hand massager further includes a right thumb air bag for pressing the right thumb and a left thumb air bag for pressing the left thumb.

For example, in a conventional massage device not provided with a thumb bladder for massaging a thumb, it is necessary to insert the thumb into another finger bladder for massaging the thumb. In contrast, according to this configuration, since the thumb airbag is provided in addition to the other finger airbags, it is possible to massage all five fingers including the thumb without replacing the inserted finger.

Further, excessive insertion of the fingers is suppressed by inserting the thumb into the thumb bladder. Thus, the back and palm of the hand are arranged at the front-rear direction position suitable for massage with respect to the air bag for the back of the hand and the massage member. As a result, the massage effect on the back and palm of the hand can be improved.

Further, it is preferable that the hand massage apparatus includes an air supply mechanism capable of supplying air from the air supply source to the two thumb airbags, the other-finger airbags, and the dorsum-side airbags independently of each other.

According to this configuration, since the two thumb airbags, the other finger airbags, and the hand back side airbag can be independently operated, the massage operation can be diversified, and the massage effect on the hand including the fingers can be further improved.

Preferably, the back side air bag may include a back side wrist air bag for pressing the wrist of the hand from the back side, and the hand massager may further include a palm side wrist air bag disposed at a position on the wrist side of the hand of the massage member of the second main wall portion so as to face the back side wrist air bag, and for pressing the wrist of the hand from the palm side.

According to this configuration, the wrist is sandwiched from the back side and the palm side by the back side wrist air bag and the palm side wrist air bag. Thus, the inserted hand is held at an appropriate position with respect to the massage member and the air bags, and the massage effect can be further improved.

Preferably, the hand massager further includes a palm-side air bag for a heel, the palm-side air bag being disposed in the second main wall portion on the finger side of the massage member and pressing the heel from the palm side.

According to this configuration, since the base of the finger on the palm side can be pressed, the massage operation can be diversified.

Preferably, the air bag for dorsal side may include an air bag for dorsal side base finger, and the air bag for dorsal side base finger may be disposed to face the air bag for palmar side base finger and press the base finger from the dorsal side.

With this configuration, the air cells for the palm side base and the air cells for the back side base can be used to massage the base. Since the finger base is sandwiched from the back side and the palm side by the two finger base airbags, the inserted hand is held. Thus, when the massage member is operated, the hand is disposed at an appropriate position with respect to the massage member, and the massage effect can be further improved.

[ Effect of the invention ]

According to the present invention, a hand including the fingers of a user can be massaged with massage pressures respectively suitable for the back of the hand, the palm, and the fingers.

face portions

41a and 42a provided on the side opposing the palm and a fixed face portion (not shown) in the same manner as the first back-side airbag 31. In the present embodiment, the first back-side airbag 31 is formed integrally with the first palm-side airbag 41. Specifically, the opposing face portion 31a of the first back-side airbag 31 and the opposing face portion 41a of the first palm-side airbag 41 are formed in a continuous belt shape. The first back-side airbag 31 and the first palm-side airbag 41 are curved and arranged in a C-shaped cross section when housed in the case 2.

The airbag main body 30 includes a first air supply portion 31b, a second air supply portion 32b, a third air supply portion 33b, and a fourth air supply portion 42b for supplying air to the first back-hand airbag 31, the second back-hand airbag 32, the third back-hand airbag 33, the fourth back-hand airbag 34, and the first palm-side airbag 41 and the second palm-side airbag 42. The first air supply portion 31b, the second air supply portion 32b, the third air supply portion 33b, and the fourth air supply portion 42b are disposed at positions corresponding to the first backside airbag 31, the second backside airbag 32, the third backside airbag 33, and the second palm side airbag 42. In the present embodiment, the first dorsum manus airbag 31 communicates with the fourth dorsum manus airbag 34 and the first palm airbag 41. Thus, the first air supply portion 31b supplies air to the first back-hand airbag 31, the fourth back-hand airbag 34, and the first palm-side airbag 41. The flow path portion for allowing the first back-hand airbag 31 and the fourth back-hand airbag 34 to communicate with each other is not shown.

The first air supply portion 31b, the second air supply portion 32b, and the third air supply portion 33b function as fixing portions for fixing the airbag main body 30 to the main body portion 23 of the housing 2. Specifically, the first air supply unit 31b, the second air supply unit 32b, and the third air supply unit 33b are inserted into the first opening 24a, the second opening 24b, and the third opening 24c of the main body portion 23 of the housing 2, respectively. For example, retaining pins are inserted into the portions of the first air supply portion 31b, the second air supply portion 32b, and the third air supply portion 33b that protrude toward the upper surface of the first main wall portion 24 of the main body 23 and are not the internal flow passage forming portions. Thereby, the airbag main body 30 is fixed to the first main wall portion 24 of the main body portion 23 of the case 2, and the airbag main body 30 is prevented from falling off from the first main wall portion 24.

The fourth air supply portion 42b functions as a fixing portion for fixing the second palm side airbag 42 to the main body portion 23 of the case 2.

The rotary table portion 61 is inclined so as to be higher from the front side toward the rear side along the inclination of the front side of the second main wall portion 25 (see fig. 4). The massage bead main body (massage member) 60 is desirably made of a soft resin, a hard resin, or a rubber.

As shown in fig. 5, the large diameter portion 62 and the small diameter portion 63 are arranged in the front-rear direction. The large-diameter portion 62 and the small-diameter portion 63 are disposed on the turntable portion 61 so that the left and right positions of the central axes extending in the front-rear direction are aligned with each other. In the present embodiment, the large diameter portion 62 and the small diameter portion 63 are formed continuously. The large diameter portion 62 and the small diameter portion 63 are integrally formed so as to overlap a rear portion of the large diameter portion 62 and a front portion of the small diameter portion 63 in a plan view (gourd-shaped in a plan view).

The large diameter portion 62 is disposed at a position corresponding to a wrist side portion of the palm. The large diameter portion 62 is disposed at a position facing the fourth airbag 34 for the back hand side.

As shown in fig. 4, a projection 61a projecting downward is provided at a central portion (the center of the rotary table portion 61) between the large diameter portion 62 and the small diameter portion 63. An output shaft 72e of a gear mechanism 72 for transmitting rotation of a motor 71, which will be described later, to the massage bead main body 60 is press-fitted into the boss portion 61 a.

The drive mechanism 70 includes a motor 71 for rotating the massage bead body 60, a gear mechanism 72, and a housing 73 for housing the motor 71 and the gear mechanism 72.

The housing 73 has an upper housing 73a and a lower housing 73 b. The upper case 73a includes a fixing portion (not shown) for fixing the drive mechanism 70 to the second main wall portion 25 of the main body portion 23 of the housing 2. The lower case 73b includes a fixing portion (not shown) for fixing the drive mechanism 70 to the lower lid portion 22 of the housing 2.

As shown in fig. 3, the motor 71 is arranged such that the axis of the motor 71 extends left and right. The motor 71 is arranged such that the output shaft 71b protrudes rightward from the motor main body 71 a. An output shaft 71b of the motor 71 is formed with, for example, a worm gear.

A first secondary gear 72b is supported rotatably about a first rotary shaft 72a provided in the vicinity of the worm wheel and projecting from the inner bottom surface of the housing. The first secondary gear 72b is formed with a helical gear (worm wheel) having a large diameter at a lower stage and a pinion having a small diameter at an upper stage, and the helical gear meshes with the worm wheel.

In the vicinity of the first secondary gear 72b, a second secondary gear 72d is supported so as to be axially rotatable by a second rotation shaft 72c provided so as to protrude in the vicinity of the first rotation shaft 72 a. The second secondary gear 72d is formed with a spur gear of a larger diameter of a lower stage and a pinion gear of a smaller diameter of an upper stage, and the spur gear of the second secondary gear 72d meshes with the pinion gear of the first secondary gear 72 b.

A spur gear 72f is meshed in the vicinity of the second secondary gear 72d, and the spur gear 72f is supported by a third rotary shaft 72e as an output shaft of the gear mechanism 72, which is provided in the vicinity of the second rotary shaft 72c in a protruding manner. The rotary table portion 61 is mounted and fixed at the upper end of the third rotary shaft 72e at a central position. Specifically, the boss 61a of the massage ball main body 60 is engaged with the upper end portion of the third rotation shaft 72 e. A groove for a bolt, for example, is formed on the upper side of the third rotation shaft 72 e. The third rotation shaft 72e can be coupled to the massage bead main body 60 by inserting and screwing the bolt into the protrusion 61a and the groove.

In the present embodiment, the gear mechanism 72 of the drive mechanism 70 includes a first rotation shaft 72a, a second rotation shaft 72c, a third rotation shaft 72e, a first secondary gear 72b, a second secondary gear 72d, and a spur gear 72 f. The rotation of the motor 71 is decelerated by the gear mechanism 72 and transmitted to the turntable 61.

The installation state of the massager 1 includes the first installation state (see fig. 8A), the second installation state shown in fig. 8B, and the third installation state.

As shown in fig. 8A, in the first installation state, the right hand or the left hand is inserted into the massager 1 in a horizontal state in which the right palm or the left palm is positioned on the lower side and the back of the hand is positioned on the upper side. At this time, the bottom surface portion 22a of the lower cover portion 22 of the massager 1 is provided as a bottom surface side installation portion (first installation portion) into which a hand can be horizontally inserted. The bottom surface side installation portion (first installation portion) may be a downward projecting convex portion or a lower surface of the leg portion.

As shown in fig. 8B, in the second installation state, the left thumb is positioned upward and the massager 1 is inserted so that the palm of the left hand is in a standing state (left-hand substantially vertical plane state) with respect to the horizontal state. At this time, the left side wall portion 21c of the upper cover portion 21 and the left side wall portion 22c of the lower cover portion 22 of the massager 1 are provided as left side installation portions (second installation portions) into which the left hand can be inserted with the thumb of the left hand positioned upward.

Although not shown, in the third installation state, the right thumb is positioned upward and the massager 1 is inserted so that the palm of the right hand is in a standing state (a state in which the right hand is substantially in a vertical plane) with respect to a horizontal state. At this time, the right side wall surface 21b of the upper cover 21 and the right side wall surface 22b of the lower cover 22 of the massager 1 serve as a right side setting portion (third setting portion) into which a right hand can be inserted with the thumb of the right hand positioned upward.

According to the first, second, and third installation states of the massager 1, the user can select whether the palm of the hand inserted into the massager is horizontal or the left and right thumbs are respectively positioned upward (for example, vertically to the horizontal). This enables the user to massage his hand in a preferred posture, thereby improving the relaxation effect.

As shown in fig. 7, the massage machine 1 has a control unit 9, and the control unit 9 controls the supply of air to the air bag main body 30 and the rotation of the massage bead main body 60.

The control unit 9 receives a signal from the operation unit 8 for controlling the massager 1. The operation unit 8 includes a power switch 81 for turning on power to the massager 1, a close switch 82 for stopping the operation of the massager 1, and a mode selection switch 83 for selecting an operation mode of the massager 1. The states of these

switches

81, 82, and 83 are input to the control unit 9 as input signals.

The control unit 9 outputs control signals to the air pump 51 as the air supply mechanism 50, the first to fourth

electromagnetic valves

52, 53, 54, and 55, and the motor 71 constituting the drive mechanism 70 based on various input signals, and controls the air bag main body 30 and the massage bead main body 60.

The control unit 9 is configured to be able to independently control supply and discharge of air by the air pump 51, opening and closing of the respective

electromagnetic valves

52, 53, 54, and 55, and valve opening degrees. Therefore, the supply and discharge of air from the

solenoid valves

52, 53, 54, and 55 to the airbags 31 to 42, and the flow rate of the supplied air are independently controlled. That is, the control unit 9 can control the timing and amount of inflation of each of the airbags 31 to 42.

The control unit 9 controls the rotation direction of the massage bead body 60 and the operation of the massage bead body 60 by controlling the motor 71. The controller 9 can control the rotational motion and the circular motion of the massage bead main body 60 about the output shaft 72e at the center of the turntable 61 as the rotation axis.

With the above configuration, the massager 1 can massage the hand including the fingers in a plurality of massage forms in which the operation of the airbag main body 30 and the operation of the massage bead main body 60 are combined. The massage mode is configured to be able to operate the airbag main body 30 and the massage bead main body 60 in accordance with an operation mode selected by the mode selection switch of the operation portion 8 among a plurality of operation modes allocated in advance.

Fig. 9 is a timing chart showing an example of operation changes at the time of activation of various elements in the first operation mode of the massager according to the present embodiment.

When the massager 1 is used, the user presses the power switch 81 to start the massager 1. When the user does not operate the mode selection switch 83 while the power switch 81 is turned on, it is considered that the first operation mode is selected. The first operation form will be described below.

At time t0, if the user turns on the power switch 81, the third solenoid valve 54 and the fourth solenoid valve 55 are opened. A predetermined flow rate of air is supplied to the left-hand thumb airbag 35, the right-hand thumb airbag 36, the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, and the fourth finger airbag 40 connected to the third electromagnetic valve 54 and the fourth electromagnetic valve 55, respectively, and these airbags are inflated. Thereby, the massage pressure is applied to the thumb and other fingers of the right or left hand of the user.

At time t1 when a predetermined time Δ t1 elapses from time t0 at which the power switch 81 is turned on, the motor 71 is turned on, and the massage ball body 60 starts a predetermined turning operation. As a predetermined turning operation of the massage bead body 60, the massage bead body 60 is turned in an arc shape around the rotation shaft (output shaft 72 e). The large diameter portion 62 of the massage ball main body 60 reciprocates in an arc shape along the edge portion on the wrist side of the palm (see arrow X in fig. 5). Thus, the parts with high massage effect can be effectively massaged. A feeling like being massaged by a person can be obtained.

At a time t2 when a predetermined time Δ t2 has elapsed from a time t1 at which the motor 71 is set in the on state, the first electromagnetic valve 52 and the second electromagnetic valve 53 are set in the open state. The first dorsal hand airbag 31, the second dorsal hand airbag 32, the third dorsal hand airbag 33, the fourth dorsal hand airbag 34, the first palmar side airbag 41, and the second palmar side airbag 42 connected to the first solenoid valve 52 and the second solenoid valve 53, respectively, are supplied with a predetermined flow rate of air. Thus, the dorsum manus of the hand inserted into the massager 1 is pressed by the inflation of the first dorsal side airbag 31, the second dorsal side airbag 32, the third dorsal side airbag 33, and the fourth dorsal side airbag 34, and the palmar side is pressed by the inflation of the first palmar side airbag 41 and the second palmar side airbag 42 and the massage bead body 60.

Thus, the back of the hand is pressed by the inflation of the first back-side airbag 31, the second back-side airbag 32, the third back-side airbag 33, and the fourth back-side airbag 34, while the palm is pressed by the massage member in addition to the first palm-side airbag 41 and the second palm-side airbag 42, and therefore a higher pressing force acts on the palm than on the back of the hand. Thus, the user's hand can be massaged with massage pressures suitable for the back and palm of the hand, respectively.

Further, it is preferable that the pressing force of the air bag and the massage member against the back and palm of the hand be steplessly adjusted by adjusting the flow rate of the air supplied to the first back-hand air bag 31, the second back-hand air bag 32, the third back-hand air bag 33, and the fourth back-hand air bag 34. Thereby, a massage with a pressing force according to the preference of the user can be provided. In addition, since only the flow rate of the air supplied to the air bag for the back side of the hand can be adjusted and the palm can be pressed by the massage beads, the structure of the massager 1 can be simplified.

The thumb and the fingers other than the thumb of the hand on the insertion side are inserted into the

thumb airbags

35, 36 and the

finger airbags

37, 38, 39, 40, thereby suppressing excessive insertion of the fingers. This enables the palm to be placed at a position suitable for massage with respect to the massage member 60 (massage beads), and the massage effect on the palm can be improved.

In particular, as shown in the first operation form, if the fingers are sandwiched by the

thumb airbags

35 and 36, the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, and the fourth finger airbag 40 at the beginning of the activation operation of the massager 1, the positions of the palms and the backs of the hands in the front-rear right-left direction with respect to the massage members 60 (massage beads) and the airbags can be positioned at the positions suitable for massage. Therefore, the massage member 60 (massage beads) can be operated at a portion where the palm massage effect is easily obtained.

Since the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, the fourth finger airbag 40, and the two

thumb airbags

35 and 36 are provided, all five fingers including the thumb can be massaged without replacing the inserted fingers.

The first back-side airbag 31, the second back-side airbag 32, the third back-side airbag 33, the fourth back-side airbag 34, the first palm-side airbag 41, the two

thumb airbags

35 and 36, the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, the fourth finger airbag 40, and the second palm-side airbag 42 can be operated independently of each other. This can diversify the massage operation and further improve the massage effect.

As described above, the wrist is sandwiched from the back side and the palm side by the fourth back side airbag (back side wrist airbag) 34 and the second palm side airbag (palm side wrist airbag) 42, and the inserted wrist is held. Thus, the hands are disposed at appropriate positions with respect to the massage member 60 and the air bags 31 to 42, and the massage effect can be further improved.

As described above, since the base of the finger on the palm side is pressed by the first palm-side airbag (palm-side base finger airbag) 41, the massage operation can be diversified.

As described above, the base of the finger can be massaged by the first palm-side airbag (palm-side base finger airbag) 41 and the first back-side airbag (back-side base finger airbag) 31. The two

air bags

31, 41 for finger base hold the finger base from the back side and the palm side. This makes it possible to appropriately hold the hand with respect to the massage member 60 when the massage member 60 is operated, thereby further improving the massage effect.

The turning operation of the massage bead body 60 may be a turning motion, and in this case, the pressing force against the portion of the palm in contact with the massage bead body 60 can be changed by the large diameter portion 62 and the small diameter portion 63 in one turning operation.

The massager 1 may be provided with a switch for adjusting the flow rate, whereby the flow rate of the air supplied to the air bag can be adjusted to achieve the massage pressure desired by the user.

The flow rate of the air supplied to the first back-side airbag 31, the second back-side airbag 32, the third back-side airbag 33, the fourth back-side airbag 34, the two

thumb airbags

35, 36, the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, the fourth finger airbag 40, the first palm-side airbag 41, and the second palm-side airbag 42 can be controlled to be gradually increased.

The air supplied to the first back-side airbag 31, the second back-side airbag 32, the third back-side airbag 33, the fourth back-side airbag 34, the two

thumb airbags

35 and 36, the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, the fourth finger airbag 40, the first palm-side airbag 41, and the second palm-side airbag 42 can be controlled to be supplied and discharged repeatedly at intervals.

The operation sequence of the air bags and the massage beads of the massager 1 can be changed as appropriate according to the purpose of massage.

Fig. 10 is a timing chart showing an example of changes in the operation of various elements in the second operation mode of the massage device according to the present embodiment.

At time t10, if the user puts the power switch 81 in the on state and presses the mode selection switch 83, the first solenoid valve 52 and the second solenoid valve 53 are in the open state. The first dorsal hand airbag 31, the second dorsal hand airbag 32, the third dorsal hand airbag 33, the fourth dorsal hand airbag 34, the first palmar side airbag 41, and the second palmar side airbag 42 connected to the first solenoid valve 52 and the second solenoid valve 53, respectively, are supplied with air at a predetermined flow rate. Thus, the dorsum manus of the hand inserted into the massager 1 is pressed by the inflation of the first dorsal side airbag 31, the second dorsal side airbag 32, the third dorsal side airbag 33, and the fourth dorsal side airbag 34, and the palm side is pressed by the massage bead body 60 in addition to the first palmar side airbag 41 and the second palmar side airbag 42.

At time t11 when a predetermined time Δ t11 elapses from time t10 at which the power switch 81 is turned on, the third electromagnetic valve 54 and the fourth electromagnetic valve 55 are turned on. The left-hand thumb airbag 35, the right-hand thumb airbag 36, the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, and the fourth finger airbag 40 connected to the third solenoid valve 54 and the fourth solenoid valve 55, respectively, are supplied with a predetermined flow rate of air to inflate these airbags. Thereby, massage pressure is applied to the thumb, and other fingers, of the right or left hand of the user.

At a time t12 when a predetermined time Δ t12 elapses from a time t11 at which the third solenoid valve 54 and the fourth solenoid valve 55 are opened, the motor 71 is turned on, and the massage ball main body 60 starts a predetermined turning operation. As the predetermined turning operation of the massage bead main body 60, the massage bead main body 60 is turned in an arc shape around the rotation shaft (output shaft 72e) as a center, as in the first operation form. The large diameter portion 62 of the massage ball main body 60 reciprocates in an arc along the edge portion of the palm on the wrist side.

Thus, the hand including the finger can be massaged in the second motion pattern different from the first motion pattern according to the preference of the user.

Next, a massager 100 according to a second embodiment will be described with reference to fig. 11. In the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals in fig. 11, and the description thereof is omitted.

The structure of the air supply mechanism 150 of the massager 100 of the second embodiment is different from that of the first embodiment. The other portions have the same configurations as those of the first embodiment, and the same effects as those of the first embodiment can be obtained.

As shown in fig. 11, the massager 100 has the same configuration as that of the first embodiment, and further includes a fourth electromagnetic valve 155, a fifth electromagnetic valve 156, a sixth electromagnetic valve 157, and a seventh electromagnetic valve 158 that are connected to the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, and the fourth finger airbag 40, respectively. Thus, the timing of inflation and deflation and the amount of inflation of the first finger airbag 37, the second finger airbag 38, the third finger airbag 39, and the fourth finger airbag 40 can be independently controlled.

The massager 100 is configured to be capable of operating the airbag main body 30 and the massage bead main body 60 in accordance with an operation mode selected by the mode selection switch of the operation unit 8 among a plurality of operation modes allocated in advance, as in the first embodiment.

Fig. 12 is a timing chart showing an example of changes in the operation of various elements of the operation form of the massager 100 according to the second embodiment.

At time t20, if the user turns on the power switch 81, the first solenoid valve 52, the second solenoid valve 53, the third solenoid valve 54, and the fourth solenoid valve 155 are opened. A predetermined flow rate of air is supplied to the first back-side airbag 31, the second back-side airbag 32, the third back-side airbag 33, the fourth back-side airbag 34, the first palm-side airbag 41, the second palm-side airbag 42, the left thumb airbag 35, the right thumb airbag 36, and the first finger airbag 37 connected to the

solenoid valves

52, 53, 54, and 155, respectively, and these airbags are inflated. Thereby, massage pressure is applied to the back of the hand, the thumb of the right or left hand, and the fingers inserted into the first finger bladder 37 of the user.

At time t21 when a predetermined time Δ t21 elapses from time t20 at which the power switch 81 is turned on, the motor 71 is turned on, and the massage ball body 60 starts a predetermined turning operation. As a predetermined turning operation of the massage bead body 60, the massage bead body 60 is turned in an arc shape around the rotation shaft (output shaft 72 e). The large diameter portion 62 of the massage ball main body 60 reciprocates in an arc shape along the edge portion on the wrist side of the palm (see arrow X in fig. 5). Thus, the parts with high massage effect can be effectively massaged. A feeling like being massaged by a person can be obtained.

At a time t22 when a predetermined time Δ t22 has elapsed from a time t21 at which the motor 71 is set in the on state, the fourth electromagnetic valve 55 is set in the off state, and the seventh electromagnetic valve 158 is set in the on state. The air in the first finger bladder 37 connected to the fourth solenoid valve 55 is discharged, and a predetermined flow rate of air is supplied to the fourth finger bladder 40 connected to the seventh solenoid valve 158. Thereby, massage pressure is applied to the back of the hand, the thumb of the right or left hand, and the fingers inserted into the fourth finger bladder 40 of the user.

Thus, the fingers can be massaged one by one, and thus the massage forms can be diversified.

In the above embodiment, the description has been given taking the case where the air bag for the back of the hand is divided into four, but the number of divisions may be increased or decreased as necessary, and solenoid valves may be provided separately. By independently controlling the plurality of air bags for the back of the hand, the massage can be further diversified.

In the above embodiment, the first dorsal side airbag 31, the fourth dorsal side airbag 34, and the first palmar side airbag 41 are described as an example of a configuration in which they communicate with each other, but these

airbags

31, 34, and 41 may be formed independently, or electromagnetic valves may be provided separately. By independently controlling the first back-hand airbag 31, the fourth back-hand airbag 34, and the first palm-side airbag 41, the massage can be further diversified.

In the above-described embodiment, the case where the air bag for the thumb and the air bag for the other finger are formed in the tubular shape so as to surround each finger has been described as an example, but these air bags for the finger may be divided vertically or horizontally.

As shown by the imaginary line in fig. 5, the airbag main body 30 may be provided with hollow-bulged or solid-bulged

massage pieces

91, 91 at a portion corresponding to a portion on the index finger side (a portion corresponding to the tiger part) where the axis of the thumb and the axis of the index finger intersect in the airbag for the dorsum hand. For example, the

massage pieces

91 and 91 may be formed by providing members that allow elastic deformation at the thumb bag side portions of the second and

third air bags

32 and 33 for the back of the hand. By the expansion and contraction of the air bag, the

massage pieces

91 and 91 can apply massage pressure to the corresponding part of the tiger's mouth of the back of the hand, and more effective massage can be realized.

The massager 1 may be provided with a heating unit having a heating function for warming the palm. In this case, the massage machine 1 includes a heating body 92 and a heating switch for switching a heating function. For example, as shown by the phantom lines in fig. 5, the heating body 92 may be provided at a portion where the palm-side finger root portion of the body 23 is located. An input signal from the heating switch is input to the control unit 9, and the heating body 92 is operated based on the input signal. Since the massage can be performed while warming the hands by the heating means, the massage effect can be further improved. Although the case where the heating main body 92 is switched to the switch of the heating main body 92 as appropriate in accordance with an input signal from the heating switch has been described, the switch of the heating main body 92 may be controlled in a previously stored operation form. Note that the heating function may be incorporated in the massage member 60.

In the above embodiment, the case where the air bags 31 to 34 for the back side, the two

air bags

35 and 36 for the thumb, the air bags 37 to 40 for the other fingers, and the

air bags

41 and 42 for the palm side are separately provided was explained as an example, but as in the modification shown in fig. 13, the air bag main body 130 may be joined to the base portion 143 such that the air bags 131 to 134 for the back side, the two

air bags

135 and 136 for the thumb, the air bags 137 to 140 for the other fingers, and the

air bags

141 and 142 for the palm side are integrated. For example, the airbags 131 to 142 are fixed to the base portion 143 by thermal welding. The airbag main body 130 is bent in a C-shaped cross section (a palm-side base portion on which the palm-

side airbags

141 and 142 are disposed faces a back-side base portion on which the back-side airbags 131 to 134 are disposed), and is disposed in the housing 2.

The base portion 143 has first to fifth air supply portions 131b to 133b, 141b, and 142b for supplying air to the first to fourth dorsum-hand airbags 131 to 134 and the first and second palm-

side airbags

141 and 142. The first to third air supply portions 131b to 133b are disposed at positions corresponding to the first to third air bags 131 to 133 for the back of the hand. In the present modification, since the first dorsal side airbag 131 and the fourth dorsal side airbag 134 are formed so as to communicate with each other, the first air supply portion 131b supplies air to the first dorsal side airbag 131 and the fourth dorsal side airbag 134. The fourth air supply portion 141b and the fifth air supply portion 142b are disposed at positions corresponding to the first palm side airbag 141 and the second palm side airbag 142.

The two

thumb airbags

135 and 136 and the other finger airbags 137 to 140 are provided with air supply portions 135b to 140b at positions on the opposite side of the base portion 143, respectively, as in the above-described embodiment. The air supply portions 131b to 133b, and 135b to 142b function as fixing portions for positioning the airbag main body 130 to the main body portion 23 of the case 2, as in the above-described embodiment.

The airbag main body 130 has a relief portion 144 formed in a palm side portion of the base portion 143. The evacuation portion 144 is provided in a region corresponding to the massage bead body 60 between the first palm side air bag 141 and the second palm side air bag 142. Thereby, the massage bead body 60 penetrates the escape portion 144 of the base portion 143. The escape portion 144 is not limited to the hole shape shown in the drawing, and may be a U-shaped cutout, or a bulging escape portion (bulging portion) 44 may be provided instead of the hole-shaped escape portion 144.

As in the modification shown in fig. 14, the housing 2 of the massage machine 1 may have an elliptic cylindrical shape. The structure of the massager 101 shown in fig. 14 differs from the above-described embodiment in the shape of the housing 102 and the shape of the operating portion 108. The other portions have the same configuration as the above-described embodiment, and the same effects can be obtained.

In the massager 101 shown in fig. 14, a hand including fingers is inserted from a hand insertion opening 111 provided at the tip of the massager 101 in a state where the palm of the right hand or the left hand is directed downward.

When the left hand is inserted into the massager 101, the thumb of the left hand is inserted into the left thumb insertion portion 102C provided on the right side of the massager 101. When the right hand is inserted into the massager 1, the thumb of the right hand is inserted into the right-hand thumb insertion portion 102D provided on the left side of the massager 1.

The dorsum manus of the hand inserted into the massager 101 is massaged by the above-mentioned dorsum manus airbags 31 to 34 (see fig. 5). The palm of the hand inserted into the massager 101 is massaged by the massage member 60 (see fig. 2). The thumb of the hand inserted into one side of the massager 101 is massaged by the left or right thumb airbags 35, 36 (see fig. 5). The other fingers of the hand inserted into the massager 101 are massaged by the

other finger airbags

37, 38, 39, and 40 (see fig. 5).

The upper surface of the massager 101 is provided with an operation portion 108. The operation unit 108 is formed of, for example, a touch panel type. The user operates the operation unit 108 to massage the hand including the user's finger by the air bags 31 to 40 and the massage member 60.

The present invention is not limited to the configuration described in the above embodiment, and various modifications can be made.
