[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air massage machine for massaging a limb (hand and leg) of a user by inflating and deflating an air bag.

[0002]

2. Description of the Related Art For example, an air massage machine for massaging a leg is known for use as a single-purpose machine and for use as an ottoman (leg rest portion) of a chair-type massage machine. The air massage machines used in these devices have air bags disposed on opposing concave inner surfaces of a substantially U-shaped treatment concave portion with the upper surface and both front and rear ends opened, and air is supplied to these air bags. The air is supplied and exhausted by the exhaust device, and the air bag is repeatedly inflated and deflated, whereby the leg of the user housed in the treatment recess is pressed and relaxed to massage.

In such an air massage machine,
A pair of air bladders individually arranged on the inner side surface of the treatment concave portion are integrally connected to each other, and a connection between the air bladders is fixed to the bottom surface of the treatment concave portion. Instead of attaching such air bags, a pair of air bags individually disposed on the inner surface of the concave portion of the treatment concave portion are made independent, and the four corners or two sides parallel to each other are formed on the inner surface of the concave portion. Attachments have been made to attach air bags by fixing them.

[0004] In the case of massaging the legs and the like of a person to be massaged, it is preferable to massage while rubbing up toward the heart of the person to be massaged because it promotes blood flow toward the heart. Have been. Also, when massaging legs, etc.,
If a tensile force can be applied, stretching can be performed accordingly, and this is also preferable for massage.

[0005] However, in the conventional air bag mounting structure described above, when the air bag is inflated and presses the legs or the like in the treatment concave portion, it is only possible to press, and the preferable massage operation as described above is performed. It cannot be obtained and its improvement is required.

Further, in the former air bag mounting structure in which the connecting portion integral with the air bag is fixed to the bottom surface of the treatment concave portion, the leg or the like accommodated in the treatment concave portion on the lower portion of the air bag located near the bottom surface of the treatment concave portion. As the air bag is inflated, the leg in the treatment concave portion tends to be pushed out when the air bag is inflated (or pushed upward when the ottoman is almost horizontal), and the massage effect is reduced accordingly. . Further, in the latter air bag mounting structure for fixing the peripheral portion of the air bag, the number of fixing components required for fixing each air bag to the inner surface of the concave portion is large, and accordingly, assembly and the like are troublesome. Therefore, the cost is high.
