[Problems to be solved by the invention]
By the way, in the massage device 1 described above, the fixing plate 3 extends so as to stand substantially along the vertical direction.
[0008]
On the other hand, the rear side surface 4a of the mounting frame 4 with which the airbag 6 abuts is such that the rear side surface 4a of the fixing plate 3 along the front side surface 3a with which the airbag 6 abuts when the airbag 6 contracts and hangs down under its own weight. Is formed.
[0009]
That is, the front side surface 3a of the fixing plate 3 facing the mounting frame 4 and the rear side surface 4a of the mounting frame 4 facing the fixing plate 3 substantially extend in the vertical direction when the airbag 6 contracts. ing.
[0010]
Therefore, when air remains in the plurality of airbags 6 disposed between the fixing plate 3 and the mounting frame 4, the airbag 6 comes into contact with the fixing plate 3 and the mounting frame 4, respectively, Until all the air in the bag 6 has been exhausted, there has been a problem that the footrest 5 cannot be positioned substantially along the vertical direction.
[0011]
In addition, it is necessary to wait until all of the air in the airbag 6 is exhausted before the footrest 5 is positioned substantially along the vertical direction, which causes a problem that it takes a long time.
[0012]
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a massager capable of positioning a footrest substantially along a vertical direction even when air remains in an airbag when the airbag contracts. It is intended to provide a device.
[0013]
[Means for Solving the Problems]
The massage device of the present invention has a seat for supporting the body, an airbag stay having one end fixed to the front edge of the seat and extending downward, and one end pivoting on the front edge of the seat. A mounting frame that is mounted so that it can be mounted, a footrest provided on the front side of the mounting frame, and a mounting frame that is disposed between the mounting frame and the airbag stay, and rotates the mounting frame when inflated. An airbag that protrudes the footrest in front of the seat and causes the footrest to hang down substantially vertically when contracted; the mounting frame rotates between the mounting frame and the airbag stay. It is characterized by gradually expanding as you move away from the fulcrum.
[0014]
According to the present invention, the distance between the mounting frame and the airbag stay gradually increases as the distance from the rotation fulcrum increases, so that the airbag disposed between the mounting frame and the airbag stay can have air remaining therein. It is possible to enter the gap between the mounting frame and the airbag stay without rotating the mounting frame. Thus, even if air remains in the airbag, the footrest can be positioned substantially along the vertical direction.
[0015]
Further, it is possible to reduce the time required to position the footrest in a state substantially along the vertical direction.
[0016]

A pair of recesses 14a and 14b for receiving feet are formed in the foot placement table 14 side by side.
[0020]
Airbags B1, B2 for massaging the thighs and buttocks are attached to the upper surface of the seat 11, which is the human body contact surface of the chair body 10a. Airbags B3 and B4 for massaging the calf are attached, and a pair of airbags B5 and B6 for massaging the waist and a pair of airbags B7 and B8 for massaging the shoulder are provided on the upper surface of the backrest portion 13. An airbag B9, which is located in the middle of these airbags B5 to B8 and massages the back extending in the longitudinal direction, is attached.
[0021]
Here, the “human body contact surface” refers to a surface that a user sitting on the seat portion 11 contacts, that is, a surface that a user's treatment section contacts.
[0022]
These airbags B1 to B9 are covered by a cover (not shown). The airbags B1 to B9 are connected to the air supply / exhaust device 100 by air hoses 17a to 17i such as rubber hoses (see FIG. 2).
[0023]
Each of the airbags B1 to B9 is inflated by the air supplied from the air supply / exhaust device 100, or contracts by discharging the air that has flowed into the airbag, thereby performing massage.
[0024]
Here, the air supply / exhaust device 100 includes a control unit 101, an air pump (air supply device) 102, a rotary valve 103, and the like, as shown in FIG.
[0025]
The control unit 101 includes a microcomputer or the like, and programs of various massage modes such as fir and beating are registered in advance. The control unit 101 is electrically connected to the air pump 102, the rotary valve 103, and the operation unit 15, respectively. The control unit 101 operates the air pump 102 and the rotary valve 103 according to an electric signal input by the user operating the operation switch of the operation unit 15, and stops and turns on and off the power. And so on. The massage mode designated by the control of the control unit 101 is executed.
[0026]
The output port of the air pump 102 is connected to the rotary valve 103. The air pump 102 has an air compressor (not shown) or the like, and generates compressed air.
[0027]
The rotary valve 103 is individually connected to each of the airbags B1 to B9, and selectively communicates the air pump 102 with one of the airbags B1 to B9 under the control of the control unit 101.
[0028]
As shown in FIG. 3, an airbag stay 20 extending downward and a mounting frame 30 to which one end 30a is rotatably mounted are provided at a front edge portion 11a of the seat portion 11. I have. In addition, in FIG. 3, the seat part 11 has shown only the framework which supports the airbag B1 etc.
[0029]
The airbag stay 20 is provided between the pair of support legs 12, 12, and is fixed in an upright state with respect to the floor. On the other hand, only one end 30a of the mounting frame 30 is attached to the seat 11, and the other end 30b is a free end. Therefore, when the airbags Ba and Bb, which will be described later, are contracted, they will hang down under their own weight.
[0030]
The airbag stay 20 is gradually inclined rearward as the front side surface 21 facing the front of the massage device 10 moves away from the rotation fulcrum S of the mounting frame 30. That is, the front side surface 21 is an inclined surface that is inclined such that the lower portion 21b projects rearward from the upper portion 21a.
[0031]
The mounting frame 30 is provided between the pair of support legs 12 so as to face the airbag stay 20. Further, a foot rest 14 is provided on a front side surface 31 which is disposed forward of the airbag stay 20 and faces forward of the massage device 10. The front side surface 31 is formed substantially along the vertical direction when the mounting frame 30 is suspended by its own weight.
[0032]
The rear side surface 32 of the mounting frame 30 facing the airbag stay 20 gradually inclines forward as the distance from the rotation fulcrum S increases. That is, the rear side surface 32 is an inclined surface that is inclined so that the upper portion 32a projects rearward from the lower portion 32b.
[0033]
Thereby, the distance L1 between the upper part 20a of the airbag stay 20 and the upper part 30a of the mounting frame 30 is close to each other, and the distance L2 between the lower part 20b of the airbag stay 20 and the lower part 30b of the mounting frame 30 is separated from each other. Become. That is, the distance between the airbag stay 20 and the mounting frame 30 gradually increases as the distance from the rotation fulcrum S of the mounting frame 30 increases (L1> L2).
[0034]
Further, a pair of airbags Ba and Bb are arranged between the airbag stay 20 and the mounting frame 30.
[0035]
The upper ends of these airbags Ba and Bb are fixed to the front edge 11a of the seat 11, respectively. Here, the airbags Ba and Bb are stacked and attached by screws.
[0036]
Further, these airbags Ba and Bb are connected to the air pump 102 via an air hose (not shown) (see FIG. 2). The communication may be performed via a rotary valve 103, an electromagnetic valve, or the like.
[0037]
Next, the operation of the massage device 10 will be described.
[0038]
In order to use the massage device 10, first, the user sits on the seat 11 and puts his or her feet into the recesses 14 a and 14 b of the footrest 14. At this time, the foot rest 14 is suspended substantially along the vertical direction (see FIG. 3). Then, the user operates the operation unit 15 to inflate and contract the predetermined airbags B1 to B9, and massages a desired portion.
[0039]
On the other hand, when the airbags Ba and Bb are inflated by the air supplied from the air pump 102, the airbags Ba and Bb abut each other and also abut the airbag stay 20 and the mounting frame 30, respectively. Here, since the air bag stay 20 is fixed, the mounting frame 30 is rotated clockwise (arrow X) in FIG.
[0040]
Then, as shown in FIG. 4, with the inflation of the airbags Ba, Bb, the mounting frame 30 is gradually rotated, and the footrest 14 can be projected forward of the seat 11. As shown in FIG. 4, the airbags Ba and Bb can be held in a state where they are not completely inflated.
[0041]
When air is further supplied to the airbags Ba and Bb, the airbags Ba and Bb are completely inflated, and the rotation angle of the mounting frame 30 is maximized as shown in FIG.
[0042]
As a result, the foot rest 14 turns the recesses 14a and 14b upward, and becomes almost horizontal with the upper surface of the seat 11. Then, the user of the massage device 10 can perform a massage with the legs extended.
[0043]
When the air in the airbags Ba and Bb is discharged and contracted from the state where the rotation angle of the mounting frame 30 is maximum as shown in FIG. 5, the mounting frame 30 is moved counterclockwise in FIG. 5 (arrow Y). ).
[0044]
Then, contrary to the case where the airbags Ba and Bb are inflated, the mounting frame 30 is gradually rotated with the contraction of the airbags Ba and Bb, and the footrest 14 hangs down substantially in the vertical direction. Become like
[0045]
Here, the space between the airbag stay 20 and the mounting frame 30 is formed so as to gradually increase as the distance from the rotation fulcrum S of the mounting frame 30 increases. Therefore, as shown in FIG. 6, even when air remains in the airbags Ba and Bb, the mounting frame 30 droops substantially along the vertical direction, similarly to the case where the mounting frame 30 droops by its own weight. can do.
[0046]
Thereby, even if air enters the airbags Ba and Bb disposed between the mounting frame 30 and the airbag stay 20, the airbags Ba and Bb do not rotate the mounting frame 30, It can enter the gap between the mounting frame 30 and the airbag stay 20. And even if air remains in the airbags Ba and Bb, the footrest 14 can be positioned substantially along the vertical direction.
[0047]
Also, here, the rear side surface 32 of the mounting frame 30 facing the airbag stay 20 is an inclined surface that is inclined such that the upper portion 32a projects rearward from the lower portion 32b. Therefore, the contact point P with the airbag Ba can be made difficult to approach the rotation fulcrum even if the rotation angle of the mounting frame 30 increases. The “contact point” refers to a point of the contact portion between the airbag Ba and the mounting frame 30 that is farthest from the pivot S.
[0048]
Since the contact point P is located relatively far from the pivot point S, even if the pivot angle of the mounting frame 30 is large, the increase in the pressing force due to the air in the airbags Ba, Bb is suppressed. can do.
[0049]
Further, here, the front side surface 21 facing the front of the massage device 10 of the airbag stay 20 is an inclined surface inclined such that the lower portion 21b projects rearward from the upper portion 21a. Therefore, the distance L2 between the lower portion 20b of the airbag stay 20 and the lower portion 30b of the mounting frame 30 can be increased without making the vicinity of the one end 30a of the mounting frame 30 largely project forward of the massage device 10.
[0050]
Then, even if the amount of residual air in the airbags Ba and Bb is large, the mounting frame 30 can be drooped substantially along the vertical direction, similarly to the case where the mounting frame 30 is drooped by its own weight. In addition, this allows the footrest 14 to be positioned substantially along the vertical direction in a short time.
[0051]
In the above-described embodiment, each of the front side surface 21 of the airbag stay 20 and the rear side surface 32 of the mounting frame 30 is an inclined surface, but either one of them may be an inclined surface.
[0052]
【The invention's effect】
It is possible to provide a massage device that can position the footrest along the vertical direction even when air remains in the airbag when the airbag is contracted.
