  By the way, when the plurality of air bags are arranged at intervals in the seat portion as described above, when the air bag is supplied with air and inflated, the upper surface of the seat portion is greatly raised in the region where the air bag exists. However, the upper surface of the seat hardly rises in a region where there is no air bag between the air bags. In particular, in an air bag that is formed by stitching and bonding two sheets along the edge, the end portion of the air bag has a relatively small expansion allowance compared to the central portion of the air bag. Become. Naturally, when such a plurality of air bags are arranged at intervals in the seat portion, the difference in the raised state of the upper surface is increased for each portion.

In addition, the seat portion is the portion of the chair-type massage machine where the user's weight is most likely to be applied. In particular, when the backrest portion stands up, the seat portion supports the majority of the user's weight.
That is, when air is supplied to the air bag as described above and inflated, a difference occurs in each part regarding the raised state of the seat. When a user sits on such a seat and adds weight, the user feels that the seat surface has sunk in the portion where the bulge in the air bag is small, and the seat surface is in the portion where the bulge in the air bag is large. It will give you a sense of excitement. As a result, depending on the arrangement of the plurality of air bags in the seat portion, there is a possibility that the user will be conscious of irregularities and feel uncomfortable.

In addition, when the air bag is inflated, the seating surface strongly presses the massage part at the part where the bulge is large, so a sufficient massage effect can be expected, but at the part where the bulge is small, the force to press the massage part is weakened so It may not be done sufficiently. Therefore, in the massage machine provided with a plurality of air bags in this way, there is also a problem that the massage effect tends to cause unevenness at each portion of the seat.
The present invention has been made in view of the above-mentioned problems, and the object thereof is to provide unevenness to the user by equalizing the amount of protrusion of the seat surface when a plurality of air bags provided on the seat portion are inflated. A chair-type massage machine that can give a comfortable massage without being conscious of it, and gives the user a flat press against the buttocks using a plurality of air bags, which makes the massage effect non-uniform There is.

In order to achieve the object, the chair type massage machine of the present invention takes the following technical means.
That is, the chair-type massage machine of the present invention includes a seat portion provided with an air bag for massage on the upper surface, armrest portions provided on both sides of the seat portion, and a backrest provided on the rear side of the seat portion. The air bag is a pair of first air bags disposed on the left and right sides on the rear side of the upper surface of the seat portion, and the center on the front side of the upper surface of the seat portion. A second air bag disposed in front of the first air bag, and the pair of the first air bag and the second air bag are arranged so that a part of each of them overlaps with each other. It is characterized by that.

  If the pair of the first air bag and the second air bag are arranged so that a part of each other overlaps the upper and lower sides in this way, the edges of the air bags having a small inflating allowance overlap with each other so that the inflating allowance is reduced. Since interpolation is performed, when the air bag provided on the seat portion is inflated, the amount of protrusion of the seat portion can be made uniform, and a comfortable massage can be given without making the user aware of the unevenness. Moreover, since a massage part can be planarly pressed using a some air bag, the massage effect without a nonuniformity can be exhibited over the whole surface in the part from a 1st air bag to a 2nd air bag. .

In addition, it is preferable that the said 2nd air bag is formed so that the length of the front-back direction may become longer than the length of the left-right direction. In this way, if the second air bag is formed long in the front-rear direction, it is possible to massage a wide range from the buttocks to the thigh with the second air bag.
The second air bag is preferably disposed so as to overlap the upper side of the first air bag, and the front end of the second air bag is fixed to the upper surface of the seat portion. preferable.
The second air bag covering a wide range in the front-rear direction is likely to be larger than the first air bag, and the position on the upper surface of the seat portion is likely to be displaced as compared with the first air bag when it is repeatedly expanded and contracted. Therefore, the pair of first air bags are arranged below the second air bag in this way and fixed so that the pair of first air bags are pressed by the second air bag, or the front end portion of the second air bag is fixed. If it fixes to the upper surface of a seat part, the position of a 2nd air bag can be made hard to shift | deviate and a 2nd air bag can be always hold | maintained on the stable position on a seat part.
The most preferable form of the chair type massage machine according to the present invention is a seat part provided with an air bag for massage on the upper surface, armrest parts provided on both sides of the seat part, and the rear side of the seat part. A chair-type massage machine provided with a backrest portion provided on the seat portion, wherein the air bag includes a pair of first air bags disposed on the left and right sides of the rear surface of the seat portion; A second air bag disposed in front of the first air bag in the center of the front side, and the pair of first air bag and the second air bag are partly up and down. The rear end left side of the second air bag is superimposed on the front end of the left first air bag, and the rear right side of the second air bag is overlapped with the right first air bag. It is superimposed on the front end, and goes from the center of the first air bag to the second air bag side through the corner. As the corner of the second air bladder is located at the top, characterized in that it is superimposed and the second air bag and the pair of first air bag is.

  The chair type massage machine of the present invention makes a comfortable massage without making the user aware of unevenness by equalizing the amount of protrusion of the seat surface when a plurality of air bags provided in the seat are inflated. Moreover, it has the effect that it is hard to produce the nonuniformity of a massage effect by giving a planar press with respect to a buttocks to a user using a some air bag.

The seat part 2 is arranged substantially horizontally so that the user can sit down on the upper surface. The seat portion 2 includes a frame, a cushion provided on the frame, and a cover that covers the frame and the cushion from the outside. In addition, illustration of a cushion, a frame, and a cover is abbreviate | omitted. And the air bag 6 mentioned later is incorporated so that it may be pinched | interposed between this cover and a cushion. On the left and right sides of the seat portion 2, armrest portions 3 are respectively provided.
The armrest portion 3 is a substantially triangular member that is provided so that its base is standing on the floor surface. The upper side of the armrest portion 3 has a round and curved shape so that the user can easily place the elbow. On the side surface of the armrest portion 3, three third and fourth air bags (side air bags) are provided one on the front and one on the side facing the seat portion 2 side.

  The third and fourth air bags are bag bodies formed so as to be able to store air, and have a structure inflating toward the seat portion 2 side by supplying air. The 3rd air bag 8 is used in order to massage a user's waist | hip | lumbar part, and the 4th air bag 9 is used in order to massage a thigh. The third air bag 8 is disposed on the rear side of the side surface of the armrest portion 3, and the fourth air bag 9 is disposed on the front side of the side surface of the armrest portion 3. These third and fourth air bags 8 and 9 are formed in a bellows shape so that the bulge allowance is larger on the upper side than on the lower side. In addition to pressing the thigh from the side, it can be massaged from above.

The backrest part 4 is a member provided on the rear side of the seat part 2 so that the user can lean from the back.

  As shown in FIG. 2, the chair type massage machine 1 of the present invention is characterized in that an air bag 6 for massage is provided on the upper surface side of the seat portion 2. The air bag 6 is composed of a first air bag (an heel massage air bag) disposed on the rear side of the upper surface of the seat 2 and a second air bag 12 (a thigh massage air bag) disposed on the front side. Has been. The first air bags are disposed on the left side and the right side on the rear side of the seat portion 2, and a pair is provided on the left and right sides. The 2nd air bag 12 is arrange | positioned in the front center of the seat part 2 upper surface, and is located ahead of the 1st air bags 11L and 11R. The pair of first air bags 11L and 11R and the second air bag 12 are arranged so that a part of each other overlaps the upper and lower sides.

Next, the configuration of the first air bags 11L and 11R and the second air bag 12 and the arrangement on the upper surface of the seat portion 2 will be described.
As shown in FIG. 3, the first air bags 11 </ b> L and 11 </ b> R are obtained by stacking two non-breathable sheets cut into a square in the vertical direction and bonding the edges thereof in an airtight manner. An air pipe 13 is connected to the lower side of the center of the first air bags 11L and 11R, and air can be supplied from the air pipe 13 to the inside of the first air bags 11L and 11R through an air pump or a valve (not shown). ing.

The first air bag includes a left first air bag 11L provided on the left rear side of the upper surface of the seat portion 2, and a right first air bag 11R provided on the right rear side of the upper surface. The left first air bag 11L and the right first air bag 11R are arranged so as to be spaced apart from each other in the left-right direction.
The first air bags 11L and 11R of the present embodiment are each formed by bonding a square sheet having a side of 100 to 200 mm.
The second air bag 12 has a non-breathable sheet cut into a rectangle having a larger area than the first air bags 11L and 11R, and is arranged so that the length in the front-rear direction is longer than the length in the left-right direction. Two sheets are stacked and the edges are bonded together in an airtight manner. An air pipe 14 is connected to the lower side of the center of the second air bag 12 in the same manner as the first air bags 11L and 11R. An air pump and a valve (not shown) are connected from the air pipe 14 to the inside of the second air bag 12. Air can be supplied.

The 2nd air bag 12 of this embodiment bonds the rectangular sheet | seat whose one side of the left-right direction is 100-200 mm and the one side of the front-back direction is 150-300 mm.
The left side of the rear end of the second air bag 12 is overlaid on the front end of the left first air bag 11L, and the right side of the rear end is overlaid on the front end of the right first air bag 11R. The arrangement in which the second air bag 12 and the first air bags 11L and 11R are overlapped varies depending on the object to be massaged and the size of the air bag, and cannot be determined in general. However, the second air bag 12 and the first air bags 11L and 11R are overlapped so that the corner of the second air bag 12 is positioned on the center of the first air bag even when the overlapping portion is the largest. Is good. Further, the second air bag 12 and the first air bags 11L and 11R are arranged so that the corner of the second air bag 12 is positioned on the line from the center of the first air bag through the corner toward the second air bag 12 side. You can also superimpose. If it does in this way, when air is supplied, the amount of protrusions of the seat portion can be made uniform between the portion where the second air bag 12 and the first air bags 11L, 11R overlap and the portion where they do not overlap. .

The front end portion of the second air bag 12 is fixed to the upper surface of the seat portion 2 using means such as adhesion, heat fusion, or sewing. If the second air bag 12 larger than the first air bags 11L and 11R is repeatedly expanded and contracted, the position on the upper surface of the seat portion 2 is likely to be displaced as compared with the first air bags 11L and 11R. Therefore, if the front end portion of the second air bag 12 is fixed to the upper surface of the seat portion 2 in this way, the position of the second air bag 12 is fixed at two locations, the front end side and the center where the air pipe 14 is provided. The second air bag 12 can be prevented from shifting and the second air bag 12 can be held at a stable position on the seat 2 at all times. The pair of first air bags 11L, 11R arranged as described above and When air is supplied to the second air bag 12, the first air bags 11L and 11R and the second air bag 12 are inflated so that the upper ends thereof are aligned with the line indicated by A in FIG. As a result, the amount of expansion of the seat 2 is uniform at all positions from the first air bags 11L, 11R to the second air bag 12, and the first air bags 11L, 11R and the second air are provided to the user. Since the bag 12 comes into contact with a uniform pressing force, the user is not conscious of irregularities, and a comfortable massage is possible. In addition, since a uniform pressing force (planar pressing force) can be exerted over the entire surface from the first air bags 11L, 11R to the second air bag 12, a uniform massage effect can be obtained.

By the way, as mentioned above, as the chair type massage machine 1 provided with the 1st air bag-the 4th air bag which massages a user as mentioned above, the massage machine of Unexamined-Japanese-Patent No. 7-124213 etc. are known, for example. . This massage machine has a pocket formed on the inner surface of the armrest 3 facing the user, and the side airbag is inflated and contracted by supplying and discharging air to and from the side airbag accommodated in the pocket. It is a mechanism for performing massage by pressing the waist and thighs of the person so as to tighten them from the outside.
However, in the above-described massage machine, the user's waist and thighs are not fixed to the seat 2 and can move relatively freely. Therefore, even if you try to press the waist and thighs using the third and fourth air bags (side airbags), the waist and thighs may escape, and sufficient massage for these parts There was a problem that the effect could not be expected.

In particular, the waist and thighs have many muscles among the body parts to be massaged and often require strong massage. However, even if a user wants to use a fir ball that can be used for strong massage, there is a risk that the user will get in the way when sitting, so there is no fir ball between the upper seat part 2 and the armrest part 3 of the massage machine. Such a massage mechanism cannot be arranged. Therefore, there has been a demand to massage the waist and thighs even when using an air bag that has a weaker massage effect than fir balls.
Therefore, in the chair type massage machine 1 of the present invention, the first air bags 11L and 11R and the second air bag 12 described above are inflated to lift the buttocks, and by lifting the buttocks, the thighs and waists are moved by the lever principle. By providing a control unit that operates an air pump and a valve so as to perform massage while strongly pressing against the side airbags 8 and 9, good massage on the thigh and waist can be performed.

Next, the content (processing program) of the process performed by the control unit, in other words, the massage aspect of the present invention will be described in detail below with reference to FIG. The following three embodiments can be considered as the massage aspect of the present invention.
In addition, before describing embodiment of the massage aspect of this invention, description of FIG. 4 is performed.
FIG. 4 shows the arrangement of the left and right first air bags 11L and 11R, the second air bag 12, the third air bag 8, and the fourth air bag 9 when the seat portion 2 is viewed from above. The air bag indicated by the solid line in the figure indicates that the air is supplied through an air pump or a valve to expand and contract, in other words, that contributes to massage. In addition, the air bag indicated by a dotted line in the drawing indicates that the air pump is stopped or the valve is closed and no air is supplied, in other words, the air bag does not contribute to the massage.

As shown to Fig.4 (a), 1st Embodiment of a massage aspect is for massaging a user's thigh strongly. In the first embodiment, air is supplied to the fourth air bag 9 via an air pump or a valve, and when the fourth air bag 9 expands, the user can tighten the thigh from the outside. It is pressed.
When air is supplied to the left and right first air bags 11L and 11R and the second air bag 12 through an air pump or a valve with the thighs pressed in this manner, the levers from the knee to the thigh are A force that squeezes according to the above principle works and the thigh is strongly pressed against the fourth air bag 9. As a result, even if the fourth air bag 9 is inflated, the thigh does not escape, and a strong massage can be applied to the user's thigh.

The procedure for supplying air to the fourth air bag 9 and the procedure for supplying air to the left and right first air bags 11L and 11R and the second air bag 12 may be reversed. That is, even if air is supplied to the left and right first air bags 11L and 11R and the second air bag 12 to lift the user's buttocks, and then air is supplied to the fourth air bag 9, As in the case, a strong massage can be applied to the user's thigh.
In addition, when massaging a user's thigh strongly, it can replace with the massage aspect of 1st Embodiment, and can also employ | adopt the massage aspect like 2nd Embodiment.

As shown in FIG. 4 (b), in the second embodiment of the massage mode, air is first supplied to the fourth air bag 9 via an air pump or a valve so that the user's thigh is tightened from the outside. This is the same as the first embodiment in that it is pressed. The point of difference between the massage method of the second embodiment and the first embodiment is that the thigh is pressed and the left and right first air bags 11L, 11R without supplying air to the second air bag 12. Only air is supplied through an air pump or a valve.
Even in this case, a force that acts on the legs from above the knees to the thighs works, and the thighs strongly press against the fourth air bag 9 to It becomes possible to give a strong massage.

In the second embodiment as well as in the first embodiment, the procedure for supplying air to the fourth air bag 9 and the procedure for supplying air to the left and right first air bags 11L and 11R may be reversed. good.
Moreover, when massaging a user's waist | hip | lumbar part strongly, it can replace with the massage method of 1st Embodiment or 2nd Embodiment, and can also employ | adopt the massage aspect like 3rd Embodiment.
As shown in FIG. 4C, in the third embodiment of the massage mode, first, air is supplied to the third air bag 8 via an air pump or a valve, and the user's waist is pressed from the outside. To do.

When air is supplied to the left and right first air bags 11L and 11R and the second air bag 12 with the waist pressed, the user's buttocks are lifted. And since the 3rd air bag 8 is strongly pressed on the waist | hip | lumbar part lifted with the buttocks and the 3rd air bag 8 is expanded, a waist | lumbar part does not escape, Therefore A user's waist | hip | lumbar part can be massaged strongly. .
The present invention is not limited to the above-described embodiments, and the shape, structure, material, combination, and the like of each member can be appropriately changed without changing the essence of the invention.
In the above embodiment, the three left and right first air bags 11 </ b> L and 11 </ b> R of the three members deployed as the air bag 6 are illustrated as overlapping the left rear end or the right rear end of the second air bag 12, respectively. However, the number of air bags 6 is not limited to three. For example, the number of air bags 6 can be increased by arranging another air bag between the left and right first air bags 11L and 11R.

  Moreover, the part which overlaps the air bags 6 is not restricted between the 1st air bags 11L and 11R and the 2nd air bags 12. FIG. For example, an overlapping portion can be provided between the left first air bag 11L and the right first air bag 11R.
