[0004]
Then, when pressurized air from an air supply source equipped with an air pump or the like is introduced into these air bag bodies A2, A3, A4, A5 through an air hose, the air bag bodies A2, A3, A4, A5 are respectively The air bag body A2 presses the shin part, the air bag body A3 presses the ankle part, the air bag body A4 presses the upper part of the foot, and the air bag body A5 presses the back part of the foot. To do.
[0005]
Moreover, if air is let out from the air bag bodies A2, A3, A4, and A5, these contract and the parts of the foot are released from the compression. Therefore, the massage effect which massages the foot F by alternately introducing and discharging the pressurized air to and from these air bag bodies A2, A3, A4 and A5 can be obtained.
[0006]
[Problems to be solved by the invention]
In the conventional air massager as described above, since the fastener A6 is provided in the upper central portion in order to attach and detach the massager A1 to and from the foot F, the air bag compresses the back of the foot at this portion. The body A4 is arranged separately on the left and right sides of the fastener A6.
[0007]
Therefore, as shown in FIG. 11, when pressurized air is introduced into these air bag bodies A4 and A5 and inflated, the air bag body A5 on the back side of the foot F has the back side of the foot as the center of expansion. Although it compresses, since the center part in which the fastener A6 was provided cannot press the back side of the foot on the back side of the foot, there was a problem that a sufficient massage effect could not be obtained at the back side.
[0008]
Further, when the air bag body A4 separated to the left and right of the fastener A6 is inflated, a portion biased to the left and right sides from the center on the back of the foot is pressed downward, and the air bag body A5 is inflated. As a result, the toe portion of the foot is pressed from both sides in the diagonally downward central direction, and the toes are crushed during the massage, causing painful problems.
[0009]
Further, in the conventional air massager, the air bags separated into the left and right at the portion that presses the instep side of the foot are not coupled with the fastener A6 as in the examples shown in FIGS. 9 to 11 described above, Some of them are joined by stitching or the like, but there are similar problems in such cases.
[0010]
Therefore, an object of the present invention is to provide an air massager that can solve the above-described problems of the prior art and obtain a high massage effect without causing pain in the toes.
[0011]
