Abstract

PROBLEM TO BE SOLVED: To massage two massaging sites, both feet for example, at a time, by means of a simple structure by mounting a roller having many stimulating protrusions in the center of a driving shaft and mounting a pair of massaging rollers on both outsides of the roller. SOLUTION: When a driving shaft 9 is rotated with a motor 6, a massaging base 23 rotates. However, when an idling portion 25 gets into a loaded condition by the insertion of feet between a pair of idling portions 25 and 26, it retains a non-rotating condition, accompanied by the rolling of a steel ball 24, and the inclination of the sliding face of the steel ball 24 causes the opposite face repeat separation and contact. Therefore, massaged areas such as feet or the like held between them are massaged by a pair of massaging rollers 22a and 22b. At this time, if loads increase, the inside massaging base 23 is withdrawn inward against an elastic body 31. The rotation of the driving shaft 9 makes the roller 16 rotate, and the rotation of stimulating balls 20... massages foot soles or the like.

It can be sandwiched and rubbed at the same time. At this time, in the case of a person with a wide foot, as described above, the inner kneading roller 22b is prevented from retreating inward to apply an excessive pressure. Also, the sphere 33 of the auxiliary rotation roller 32
As described above, the sole can be simultaneously stimulated.

Further, each pair of rubbing rollers 22a, 22b
Since the outer rubbing roller 22a and the inner rubbing roller 22b are symmetrically inclined in directions opposite to each other with respect to the drive shaft 9, the massaged portion can be sandwiched and rubbed in the same manner from the left and right.

Further, by placing the foot on the rotating roller 16 at the center, a massage that stimulates the sole can be performed.

In the above embodiment, each pair of the rubbing rollers 2
2a and 22b, the inner and outer kneading rollers are inclined in directions opposite to each other symmetrically with respect to the drive shaft 9, but need not necessarily be inclined in opposite directions. For example, as shown in FIG. The outer kneading roller 22a may be orthogonal to the drive shaft 9. In this way, the width (length in the direction of the drive shaft 9) of the whole massage machine can be shortened, and compactness can be achieved.

3 will be described. Here, the kneading base 2 constituting each of the kneading rollers 22a and 22b will be described.

When the drive shaft 9 rotates, the outer kneading roller 22a moves the idler portion 25a in the drive shaft direction because the sliding surface of the steel ball 24 is parallel to the drive shaft 9. Since the sliding surface of the steel ball 24 of the inner kneading roller 22b is not parallel to the axis of the drive shaft 9 but is inclined, the idler portion 25b changes the inclination angle with respect to the drive shaft 9 to allow the opposite idler. The operation of approaching and separating from the portion 25a is repeated, and the massaged portion sandwiched between the portions can be rubbed. When the foot is sandwiched between the idler portions 25a and 25b, the massaging body 28b of the inner massaging roller 22b hits the arch exactly, and massages by pressing the arch from the side with the protrusion 29. Can be.

Even if the inner kneading roller 22b is made orthogonal to the drive shaft 9 instead of the outer kneading roller 22a, the same effect that the width of the whole massage machine can be minimized and the compactness can be achieved can be achieved. can get.

Each pair of rubbing rollers 22a, 22b
Have the same inclination phase with respect to the drive shaft 9 of the inner and outer kneading rollers, that is, as shown in FIG. 1, the inner and outer kneading rollers 22a of one of the kneading rollers (for example, on the left side in FIG. 1),
When the interval between 22b is maximum, the other (on the right side in FIG. 1)
The distance between the inner and outer kneading rollers 22a and 22b of the kneading rollers is also maximized, and conversely, both kneading bases 23 are fixed to the drive shaft 9 so as to be minimized at the minimum, but the phase is shifted by 180 degrees. , One of the inner and outer rubbing rollers 22a, 2
The kneading base 23 may be fixed to the drive shaft 9 so that the interval between the inner and outer rubbing rollers 22a and 22b of the other rubbing roller is minimized when the interval between 2b is maximum.

In this way, the massaged parts such as both feet sandwiched between the left and right rubbing rollers are alternately sandwiched and rubbed, and the burden on the human body can be reduced since both feet are not sandwiched at the same time. The load on the drive motor can be reduced,
The size can be reduced without having to increase the output of the drive motor.
