It has become.
[0021]
Further, the massaging device 2, as shown in Figure 6, each air bag 5 ... 9 ... and another air bag 31 includes a flexible air hose 32 connected thereto, the hose 32 The connection port body 33 attached to the tip of the body, the acupressure treatment element 34 superimposed on the airbag 31 via the flat treatment element base 37, and the treatment element 34 and the airbag 31 were accommodated. A front cloth 35 is provided. The massage tool 2 is considerably thinner than the main body case 3 and is formed in a small size, and the airbag 31 is used as a second airbag separate from the airbags 5. .
[0022]
The connection port body 33 is detachably connected to the connection portion 21, and as shown in FIG. 5, an O-ring 36 is provided on the outer periphery of one end portion of the straight pipe portion 33 a having a smaller diameter than the screw hole 23. And a flange 33b having a larger diameter than the screw hole 23 is integrally formed on the outer periphery of the other end portion. The straight pipe portion 33a is inserted into the connection portion 21 in place of the plug 27, and the insertion dimension is regulated by the flange 33b coming into contact with the outer surface of the side wall of the upper case member 3a. The ring 36 is in contact with the inner surface of the small diameter portion of the connecting cylinder 22 so as to maintain airtightness. The air hose 32 has a length sufficient to dispose the air bag 31 at an arbitrary position such as the waist, back, or neck of the user with the connection port 33 connected to the connection 21. .
[0023]
Next, the case where the said massage tool 2 uses the air massage machine 1 previously equipped as an accessory is demonstrated.
[0024]
First, the massage tool 2 is communicated with the air supply / exhaust means 13. This communication is performed by first removing the plug 27 and opening the screw hole 23 of the connection portion 21, and then inserting the straight pipe portion 33 a in the connection cylinder 33 of the massage tool 2 into the screw hole 23. As a result, as shown in FIG. 5, the sheet-like on-off valve 24 is pushed open by the straight pipe portion 33a, and an O-ring 36 is formed between the straight pipe portion 33a and the small diameter portion of the connection cylinder 22 of the connection portion 21. Thus, the massage device 2 is communicated with the branch pipe 17 of the air supply / exhaust means 13.
[0025]
In this state, the air massage machine 1 connected to the power source is moved to the lower limb side of the user, and the user's lower limbs are individually accommodated and set in the pair of treatment grooves 4 and set, The massage tool 2 is applied to the treatment site at any position other than the lower limb desired by the user. Specifically, the massage tool 2 is disposed such that the massage tool 2 is sandwiched between the massage tool 2 and the floor or the like so that the treatment element 34 of the massage tool 2 is positioned on the arbitrary treatment site side. In this case, the air hose 32 can be sandwiched at a desired position using the flexibility.
[0026]
Next, the user may give necessary operation instructions via the remote control device 14. Then, the air supply / exhaust means 13 intermittently operates the air pump 15 according to the designated massage mode and opens / closes the exhaust valve 19 , so that the air supply / exhaust means 13 is guided through the air hose 16 each time the air pump 15 is operated. The compressed air is distributed in the distribution pipe 17 and is sent to the main airbag 5 and the auxiliary air bag 9 via the air hoses 11 via the air hoses 6 and at the same time via the air hose 20 to the connecting portion. The compressed air is also sent to 21, and the air is also sent to the air bag 31 of the massage tool 2 communicated with the connection portion 21 via the air hose 32. Further, since the exhaust valve 19 is opened during the period when the operation of the air pump 15 is interrupted, the air flowing out from the air bags 5, 9, 31 is exhausted from the exhaust valve 19 through the air hose 18.
[0027]
Therefore, each airbag 5, 9, and 31 repeats the operation | movement which expand | swells when air is supplied as mentioned above, and shrink | contracts when air is exhausted. Thereby, the main airbag 5 presses the lower limbs from both sides and presses and relaxes and massages the lower limbs. Similarly, the auxiliary airbag 9 presses the lower limbs from below with the acupressure treatment element 10 and Relax and massage with the release. At the same time, the air bag 31 of the massage device 2 massages another arbitrary treatment portion such as the back away from the lower limbs through the treatment element 34 and relaxes it by releasing it.
[0028]
By using the massage device 2 in combination, other optional treatment parts that cannot be massaged by the air bags 5 and 9 of the treatment groove 4 of the air massage machine 1 can be massaged synchronously using the massage device 2. In that case, the massage tool 2 can be arbitrarily arranged at a position desired by the user by the flexible air hose 32. That is, there is an advantage that a plurality of places including the treatment part at an arbitrary position can be massaged simultaneously.
[0029]
Moreover, the massage time with the massage device 2 is the same as the massage time with the airbags 5 and 9, and even after the massage of one system is finished, the massage of the other system is not continued, so it is easy to use. . In the combined use of the massage device 2, since the connection portion 21 and the connection port body 33 are hermetically sealed by the O-ring 36, air from the branch pipe 17 to the massage device 2 leaks at the connection portion 21. Thus, the massage power of the massage tool 2 does not decrease.
[0030]
Since the connecting cylinder 33 of the massage device 2 can be attached to and detached from the connection portion 21, the air massage machine 1 can be used alone without using the massage device 2 by pulling out the straight tube portion 33 a from the connection portion 21. it can. In the detached state of the massage tool 2, the sheet-like on- off valve 24 of the connecting portion 21 is raised due to its elasticity. Therefore, when the air massage machine 1 is used alone, the sealing on-off valve 24 is in close contact with the peripheral wall surface of the screw hole 23 by the pressure of the air guided to the connection portion 21 through the air hose 20. The screw hole 23 is securely closed. By closing the flow path of the connecting portion 21, the compressed air is prevented from leaking outside through the screw hole 23, so that the air bags 5 and 9 can be reliably inflated by a predetermined amount for massage. it can.
[0031]
Since the opening / closing valve 24 that opens and closes the flow path of the connection portion 21 using the insertion of the connection port body 23 and the air pressure as described above is a sheet shape, the connection portion 21 is reliably sealed with a simple structure. can do.
[0032]
Moreover, since the massage tool 2 which has the flexible air hose 32 for arrange | positioning the airbag 31 in the position corresponding to arbitrary treatment parts as mentioned above can be removed from the air massage machine 1 and can be separated, air massage By separating in the handling such as packing and storing of the machine 1, the massage machine 1 itself can be handled independently regardless of the massage tool 2. As a result, the massage device 2 with the air hose 32 is not cluttered, so that the handleability of the air massage machine 1 during packaging and storage can be improved.
[0033]
The present invention is not limited to the first embodiment. For example, the treatment element for acupressure shown in massage device 2 in Oite the first embodiment 34 may be omitted. The present invention can also be carried out by providing a connecting portion on the massage machine body even in a chair type or mat type air massage machine.
[0034]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0035]
According to an air massager according to the invention of claim 1, for the same time as air supply and exhaust to the first air bag, the second air bag communicated with a massaging device to the connection portion of the massage machine As well as being able to supply and exhaust air, the massage device can be placed at any position desired by the user with the flexible deformation of the flexible air hose , so massage at multiple locations including the treatment part at any position An air massage machine that can be used simultaneously.
[0036]
Further, according to the first aspect of the invention, in handling such as packing and storing of the air massage machine, the massage machine itself can be handled independently of the massage tool, so that the massage tool can be cluttered. In addition, it is possible to improve the handling of the air massage machine when packing and storing it, and to prevent air leakage from the connecting portion by the flow path opening / closing means.
[0037]
In addition, according to the first aspect of the present invention, the connection port of the connection portion is opened and closed by using the insertion of the connection port body into the connection portion and the air pressure accompanying the removal of the connection port body. Since this is performed with a sheet-like on-off valve that opens and closes, air leakage can be prevented with a simple structure when a massage tool for massaging a treatment portion at an arbitrary position is removed and used.
