Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air massager for inflating and deflating an air bag by supplying and exhausting air to massage a treatment area.

[0002]

2. Description of the Related Art An air massager for inflating and deflating an air bag by supplying and exhausting air to massage a treatment area has been widely known as a mat type or chair type air massager.

And, this type of air massager is
For example, in a mat type air massager, a neck air bag or leg air that massages the neck, shoulders, spine, hips, hips, thighs and legs (calves) etc. on the upper surface of the inside of the mat. The bags are arranged at predetermined positions with a space therebetween, and these air bags are expanded and contracted in a predetermined order to perform massage.

The air bag 140 used in the conventional air massager is in a flat state as shown by the solid line in FIG. 8 when it is contracted, as shown in FIG. In the expanded and expanded state, as shown by a chain double-dashed line in the figure, the central part has the largest bulge and the bulge gradually decreases toward both end edges.

Therefore, when the air bag 140 is inflated, the portion of the portion to be treated which is pressed against the central portion is strongly pressed, but the pressing force decreases from the central portion toward both end edges, and therefore the above-mentioned The area away from the central part is not massaged enough. Further, when the user wants to massage a portion of the treatment target portion away from the central portion, the user must move the body in either direction so that this portion is located in the central portion of the airbag. .

That is, since the air bag used in the conventional air massager including the mat type air massager has the largest bulge in the central portion and the smaller the bulge toward both edges, Although the local area, that is, the narrow range of the treated area is strongly pressed, the pressing force in the vicinity of both end edges is weak, so a good massage effect cannot be obtained, and in order to massage the desired part, Since the body has to be moved, there is a problem that it is not easy to use and a sufficient satisfactory massage cannot be performed.

[0007]

As described above, in the conventional air massager, the shape of the air bag used for this is such that the central part has the largest bulge and the bulges become smaller toward both edges. Therefore, since a sufficient pressing force can be obtained only in a narrow range corresponding to the central portion of the treated portion, a good massage effect cannot be obtained and there is a problem that the usability is poor.

[0008]

The present invention has been made in view of the above circumstances. The invention according to claim 1 has a support base having an arrangement surface facing the treated portion, and an arrangement surface of the support base. A plurality of air bags that are inflated and deflated by the supply and exhaust of air, and an air supply and exhaust device that supplies and exhausts air to and from the air bag under the control of a control means. In an air massager that supplies and exhausts air to massage the treated part, the plurality of air bags contract flat in the exhausted state, and the bulge of the central portion is the largest in the air-supplied state and ends from the central portion. The bulge is gradually reduced toward the edge, and adjacent air bags are arranged on the arrangement surface by overlapping the edge portions of each other. It is obtained by the air massager inflating and deflating to supply and exhaust air simultaneously to the air bag to the adjacent by the control means.

As described above, according to the first aspect of the present invention, the plurality of airbags are flatly contracted in the exhausted state, and the bulge of the central portion is the largest in the air-supplied state, and the bulge is increased from the central portion toward the edge.

A support shaft 35 is provided in the lower rear part of the support shaft 3. The support shaft 35 is rotatably attached to the front part of the body frame (not shown), so that the leg mounting table 30 uses the support shaft 35 as a fulcrum. It is attached to the front portion of the seat portion 11 so as to be vertically rotatable. The leg mounting table 30 can be positioned at any rotation position by a rotation means (not shown).

As shown in FIGS. 2 and 5, the opposing walls 31a to 33a, which are the opposing surfaces of the pair of grooves 36, that is, the central wall 31 and the side walls 32 and 33, face each other. Similar to the pair of first leg airbags (hereinafter simply referred to as the first airbag) 40 as the airbags arranged to face each other, the pair of the second pair of airbags to face each other. Leg airbag (hereinafter simply referred to as the second airbag) 4
1 are arranged respectively.

The first air bag 40 and the second air bag 41 are flat as shown by the solid line in the contracted state in which air is exhausted as shown in FIG. Is supplied, that is, supplied with air and expanded to almost the maximum (a predetermined expansion amount), the bulge at the center is the largest and the bulge gradually increases toward both edges as shown by the two-dot chain line in the figure. It is formed in a smaller shape.

As shown in FIGS. 2 and 5, the first air bag 40 and the second air bag 41 are formed by superposing the edge portions 40a and 41a adjacent to each other so as to overlap each other with the opposing wall 31a. Through 33a.

As described above, the first air bag 40 and the second air bag 41 have their respective end edge portions 40a and 41a overlapped with each other to face the opposing walls 31a to 33a.
Since they are arranged opposite to each other, when the air is exhausted and contracted, both end edge portions 40a and 41a are overlapped but contracted to a flat state as shown by the solid line in FIG. From the opposing walls 31a to 33a
It lies flat on the wall surface of the opposing walls 31a and 33a (in FIG. 5 only).

Further, when air is supplied to expand substantially to the maximum, as shown by the chain double-dashed line in FIG. 5, both edge portions 40a and 41a have less bulge than the central portion, but both edge portions 40a and 41a bulge. Is superposed,
When the bulges of both are combined, the bulges are about the same as the bulges of the central portion. Therefore, both edge portions 40a, 41a
Without overlapping, that is, when both edge portions 40a and 41a are arranged close to each other without overlapping, there is no valley-like depression between both edge portions 40a and 41a, and the center of the first airbag 40 is not formed. Since the same inflated state is obtained over a wide range from the vicinity of the portion to the vicinity of the central portion of the second airbag 41, the wide range of the leg that is the treated portion, that is, the vicinity of the knee as shown in FIGS. 3 and 5. It is possible to press the range from the part to the vicinity of the ankle substantially uniformly.

Further, the pair of first air bags 40.
The second air bag 41 and the second air bag 41 are connected to each other by a belt-like connecting member 42. The groove 36 is formed on the back surface of the intermediate portion of the connecting member 42 along the groove direction of the groove 36.

Then, by selecting a plurality of fixtures provided with the fixture 43 in the groove 36, that is, either the fixture located on the front side (left side in FIG. 2) or the fixture located on the rear side. It is possible to adjust the overlapping margin, that is, the width dimension of overlapping, of the edge portions 40a and 41a adjacent to each other by selectively selecting and connecting.

Then, by connecting the connecting member 42 to the fixture provided in the groove 36, the fixture 43 to be attached is
The pair of first air bag 40 and second air bag 41 includes the opposing walls 31a and 32a, 33a.
It is arranged to be located at.

Then, the edge portions 40 of the first air bag 40 and the second air bag 41 which are adjacent to each other.
Since a and 41a can control the polymerization margin, for example, as shown in FIG. 7, when the first air bag 40 and the second air bag 41 are arranged so as to be polymerized to the central portion, when they are inflated, Since the central portions having large bulges are overlapped with each other, the bulge of the first airbag 40 is added to the bulge of the second air bag 41, and thus the second air bag 41 largely protrudes inside the groove 36. The portion to be treated, that is, the leg portion, corresponding to this largely protruding portion is strongly pressed.

Therefore, when the user desires to massage a portion of the treatment area with a strong pressing force, the user can increase the polymerization margin of the first air bag 40 and the second air bag 41. Groove 3 to the center
6 are arranged on the opposing walls 31a to 33a, and when the user wants to press the treated area over a wide range and massage it even if the pressing force is not so strong, as described above, the first airbag 40 and the first airbag 40 The overlap margin of the second air bag 41 may be reduced, that is, both end portions 40a and 41a may be overlapped and disposed on the opposing walls 31a to 33a of the groove 36.

This selection, that is, the control of the polymerization rate, is performed by
Since the first air bag 40 and the second air bag 41 are movable along the groove direction of the groove 36 as described above, the first air bag 40 and the second air bag 4
This can be easily done by moving 1 in the groove direction.

The adjustment of the stacking allowance is made such that one of the first air bag 40 and the second air bag 41 is not moved, but either one is fixed and only the other is movable. It's okay.

Further, as shown in FIG. 4, one ends of hoses 44a and 44a are connected to the pair of first air bags 40 arranged in the pair of grooves 36, respectively.
The hoses 44a, 44a are combined into a single hose 44b , further combined into a single hose 44, and connected to a first solenoid valve 53 described later. Similarly, one ends of the hoses 45a, 45a are connected to the pair of second airbags 41 respectively arranged in the pair of grooves 36, and the hoses 45a, 45a are one hose 45b.
And a single hose 45 and are connected to a second solenoid valve 54 described later.

Next, the air supply / exhaust device 50 is, as shown in the control block diagram of FIG. 4, an air generating means 51 including an air pump and the like, and the hose 5 is connected to the air generating means 51.
An air distributor 52 composed of a rotary valve and the like connected by 6, a hose 57 branched from the hose 56,
A pair of hoses 57a further branched from this hose 57
A first solenoid valve 53 and a second solenoid valve 54, which are air distributors connected to, and control the first solenoid valve 53 and the second solenoid valve 54, the air generating means 51, and the air distributor 52. The control means 55 is composed of a microcomputer or the like.

Further, the control means 55 is provided with a mode setting button, a massage time setting button, a start button, etc., which are not shown, from a remote control device (hereinafter referred to as input means) 58, and various massage modes, massage time, etc. An input signal is input.

The massage mode is a whole body massage mode in which the neck air bag 20 or the thigh air bag 25, which is well known in the related art, is inflated and compressed in order to massage the neck portion or the thigh area, and the neck air bag 20 or the waist portion. Upper body massage mode for inflating and deflating the air bag 23 to massage the neck or waist, lower body massage mode for inflating and deflating the butt air bag 24 and thigh air bag to massage the butt and thigh, air bag for the neck. In addition to inflating and deflating 20 to thigh airbags 25 individually to massage each part of the neck or thigh independently, a leg massage, which is a characteristic massage mode of the present invention, is massaged. The massage mode includes a simultaneous expansion / contraction mode and a sequential expansion / contraction mode.

Next, the operations of the simultaneous expansion / contraction mode and the sequential expansion / contraction mode will be described together with the control shown in the control block diagram of FIG. The description of the whole-body massage mode and the like similar to the conventional one will be omitted.

First, the simultaneous expansion / contraction mode will be described.
This expansion / contraction mode is a mode in which air is supplied to / exhausted from the first air bag 40 and the second air bag 41 at the same time to perform massage, and the simultaneous expansion / contraction mode covers a wide range of treatment areas. There is a case where both are simultaneously pressed, and a case where a portion having a treated portion is locally strongly pressed and massaged.

Here, only the case of simultaneously pressing the treatment area over a wide range will be described. Therefore, the overlap margin between the first air bag 40 and the second air bag 41 is arranged in the groove 36 in a small state.

When the user desires this simultaneous expansion / contraction mode, the user sits down on the seat portion 11 and the groove 3 of the leg mounting table 30.
The leg is positioned at 6, and the leg is rotated and positioned until the height of the leg reaches a desired position. Then, after setting the simultaneous expansion / contraction mode and the massage time from the input means 58, the start button is operated.

Then, the control means 55 controls the air generating means 51, the first solenoid valve 53 and the second solenoid valve 54 to supply air to the first air bag 40 and the second air bag 41 at the same time. Then, when the first airbag 40 and the second airbag 41 reach the predetermined maximum inflation amount, the control means 55 stops the air generating means 51 and causes the first airbag 40 to operate.
The first solenoid valve 53 and the second solenoid valve 54 are controlled to be in an exhausted state so that the air in the second air bag 41 is exhausted at the same time.

When the air in the first air bag 40 and the second air bag 41 is exhausted, the control means 55 again causes the air generating means 51 and the first solenoid valve 53.
And the second solenoid valve 54 is controlled to supply air to the first air bag 40 and the second air bag 41. Then, this operation is repeated for the set time, and when this set time elapses, the control means 55 stops the operation of the air generating means 51, the first solenoid valve 53 and the second solenoid valve 54.

By repeating the inflation and deflation of the first air bag 40 and the second air bag 41 in this manner, the portion to be treated, that is, the leg portion is repeatedly pressed and relaxed, and massage is performed. . When the first air bag 40 and the second air bag 41 are inflated, both end edge portions 40a and 41a as described above.
Since the swelling of the first airbag 40 is substantially the same as the swelling of the central portion of the first airbag 40, the central portion of the first airbag 40 and the both edge portions 40a and 41a are overlapped.
The leg portion can be pressed in a wide range over the overlapping portion a and the central portion of the second airbag 41.

Therefore, a wide range of legs can be massaged at the same time, so that the massage effect can be improved.
it can. Further, the first air bag 40 and the second air bag 41 have opposing surfaces 31 a, 32 a on both sides of the groove 36.
And 31a and 33a are arranged to face each other,
The legs are pressed so as to be sandwiched from both sides, and a good massage effect can be obtained.

Of course, it is also possible to combine the simultaneous expansion and contraction mode with each of the massage modes described above, for example, upper body massage, so that the leg massage and the upper body massage can be performed at the same time.

In the case where the portion having the portion to be treated is strongly pressed and massaged locally, the first air bag 4 is used.
It is possible to perform a massage that locally strongly presses by superimposing the overlap margin of 0 and the second air bag 41 to a large extent, that is, by overlapping the middle portion and arranging them in the groove 36 and performing the same operation as above . In this case, in addition to being able to massage the wide area of the legs at the same time, the overlapping portion is strongly pressed , so that a good massage can be performed.

Next, the sequential expansion / contraction mode will be described. In this sequential inflation / deflation mode, the first airbag 40 and the second airbag 41 are alternately inflated, that is, one of the airbags is first started to be inflated to be inflated, and then the one of the airbags is inflated. While evacuating air, start air supply to the other air bag to inflate it, and then exhaust air from the other air bag and inflate air to the one air bag to inflate it. . Then, this operation is repeated to massage the portion to be treated, that is, the leg portion.

When the user desires to massage in this sequential expansion and contraction mode, the seat portion 11
Sit down and position the leg in the groove 36 of the leg mount 30, and rotate the height of the leg to a desired height. Then, after setting the expansion / contraction mode and the massage time sequentially from the input means 58, the start button is operated.

Then, the control means 55 operates the air generating means 51, and at the same time, controls the first air bag 40.
The first solenoid valve 53 and the second solenoid valve 54 are controlled so that the air is supplied to and discharged from the second air bag 41 alternately as described above.

That is, the control means 55 controls the second solenoid valve 5
The air supply to the first air bag 40 is started with the first solenoid valve 53 being in the air supply state while the air supply to No. 4 is not possible. Then, when the first airbag 40 is brought into a predetermined inflated state, the control means 55 then puts the first solenoid valve 53 into the exhaust state and simultaneously puts the second solenoid valve 54 into the air supply state.

By this control, first, in the state where the second air bag 41 is contracted, the first air bag 4 is
When 0 is inflated and the first airbag 40 is inflated to a predetermined state, the exhaust of the first airbag 40 is started, and at the same time when the exhaust is started, the air is supplied to the second airbag 41. It starts and expands.

When the second air bag 41 inflates to a predetermined state, the second air bag 41
Of the air is started, and at the same time as the start of the exhaust, the supply of air to the first air bag 40 is started and the air is inflated. This state is repeatedly massaged until the set time has elapsed.

As described above, in the sequential inflation / deflation mode, the first airbag 40 and the second airbag 41 are inflated or inflated sequentially, that is, alternately, so that the first airbag 40 and the second airbag 41 are inflated. The portion to be treated, that is, the leg portion, corresponding to the bag 41 is alternately pressed and relaxed by the first airbag 40 and the second airbag 41, so that a massage in a so-called massage state is performed and a good massage effect is obtained. Is obtained. In addition, since alternately repeated pressing and relaxing promote blood circulation, the massage effect can be improved also from this point.

As described above, in the massage machine 1, the first air bag 40 and the second air bag 41 contract flatly in the exhausted state, and the bulge of the central portion is the largest in the air-supplied state from the central portion. The first air bag 40 and the second air bag 4 are formed in a shape in which the bulge is gradually reduced toward the end edge and are adjacent to each other.
1. The footrest 3 is formed by superposing the end edge portions 40a and 41a of 1 on each other.
No. 0 facing walls 31a to 33a, and control means 55
Since the first air bag 40 and the second air bag 41 which are adjacent to each other are supplied or exhausted simultaneously or alternately, that is, sequentially to be expanded and contracted, the end edges are superposed when expanded and contracted at the same time. As a result, the bulge amount as a whole is almost the same as the bulge in the central part, and it is possible to press a wide area of the leg part, that is, the treated part at the same time with the same pressing force. The massage effect can be improved because the massaging effect can be obtained because the parts can be alternately pressed and relaxed.

[0060] Further, the first air bag 40 and the edge portion of the second air bag 41 by polymerizing to the central portion, by arranging the opposing walls 31a to 33a, in the portion provided in the polymerization The bulge can be further increased . this
Therefore, a stronger pressing force can be applied to the portion of the treated portion corresponding to the central portion than the other portions, and the massage effect can be improved.

Further, at least one of the first air bag 40 and the second air bag 41 is movably arranged with respect to the opposing walls 31a to 33a, and the overlapping positions of both air bags 40 and 41 are at least mutually. Edge 40
Since it is possible to select a, 41a or the central portion, it is possible to adjust the overlapping range, that is, the overlapping margin of the air bags adjacent to each other, so that a wide range of the treated portion can be pressed with a substantially uniform pressing force, and It is possible to arbitrarily set to press with a stronger pressing force than other parts, and the user can select a desired pressing force.

Further, since the first air bag 40 and the second air bag 41 are arranged so as to face each other, the leg portion, that is, the treated portion can be pressed from both sides, so that a strong pressing force is exerted on the treated portion. It can be applied and a good massage effect can be obtained.

In the above embodiment, the case where the adjacent air bags are the two air bags, the first air bag 40 and the second air bag 41, has been described. It can also be used as an air bag.

Further, in the above-mentioned embodiment, the first air bag 40 and the second air bag 41 are arranged to face each other, but they may not be arranged to face each other.

Further, in the above-mentioned embodiment, the leg mounting table 30 for massaging the first air bag 40 and the second air bag 41, which are adjacent to each other, to the leg portion as the treated portion.
It is configured to be disposed, which, by polymerizing an edge portion adjacent to each other is applied to an air bag disposed seat 11, the backrest 12, buttocks or back is the treatment site It may be configured to massage the part.

In the above description, the case where the massage machine is a chair-type air massage machine has been described.
This allows the air massager to be another type, for example, a mat type air massager.

[0067]

As described above, according to the first aspect of the present invention, a plurality of airbags are contracted in a flat shape in the exhausted state, and the bulge of the central portion is the largest in the air-supplied state. The air bags adjacent to each other are formed on the support surface by overlapping the edges of the air bags adjacent to each other, and the air bags adjacent to each other are simultaneously controlled by the control means.
Since it is designed to expand and contract by supplying and exhausting air to,
