Description of the Related Art Conventionally, this kind of massage machine, as disclosed in, for example, Japanese Utility Model Publication No. 15497/1990, rubs a pair of rubbing rollers with, for example, a foot (which may be a calf or an ankle). Rolling massage can be performed by applying a sole or a calf to a stimulating projection of a rotating roller outside the rubbing roller.

[0003] However, in the conventional apparatus, since the kneading roller for performing kneading and the rotating roller for performing rolling massage are independent, rolling massage cannot be performed simultaneously while kneading one massaged part.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a massage machine which can simultaneously perform massage and rolling massage on one massaged part and can simultaneously perform rolling massage on other massage parts. As an issue.

[0005]

According to the present invention, a pair of rubbing rollers inclined in opposite directions are mounted on a drive shaft rotated by a motor, and a plurality of stimulating protrusions are located outside the rubbing rollers. With a rotating roller having a part, an auxiliary rotating roller having a stimulating projection and being rotated by the drive shaft is provided between the kneading rollers, and a driving shaft of the stimulating projection of the auxiliary rotating roller is provided. Is lower than the height of the tip of the kneading roller from the drive shaft.

With this configuration, the massage can be performed by sandwiching the massaged portion between the pair of massage rollers, and at the same time, the rolling massage is performed on the massaged portion by the stimulating protrusion of the auxiliary rotating roller. be able to. In addition, rolling massage can be performed on another massaged site by using the stimulating projection of the rotating roller outside the rubbing roller.

Here, if the number of stimulating projections of the auxiliary rotating roller is smaller than the number of stimulating projections of the rotating roller located outside the kneading roller, the stimulating projection of the auxiliary rotating roller is reduced. The stimulus given to the massaged part can be made to feel stronger than the stimulus given to the massaged part by the rotating roller located outside the rubbing roller.

In addition, the stimulating projection of the auxiliary rotating roller can be rotated on the auxiliary rotating roller, or can be formed integrally with the auxiliary rotating roller base fixed to the drive shaft, so that the massaged portion can be formed. Different stimuli can be given.

Further, the present invention provides the rubbing roller which is slidable in the axial direction with respect to a drive shaft, and a pair of rubbing rollers are always provided between the rubbing roller and the rotating roller in a direction in which the rubbing rollers approach each other. With the aid of a biasing elastic body, the rubbing roller is retracted in a direction away from each other by a load applied to the rubbing roller, and the amount of approach to each other is regulated by the auxiliary rotating roller.

[0010] With this configuration, when an excessive load is applied between the pair of massaging rollers from the massaged site, the pair of massaging rollers retreat away from each other, thereby preventing excessive pressure from being applied to the massaging site. At the same time, the closest interval between the kneading rollers can be regulated by the auxiliary rotating roller, and the interval can be prevented from narrowing further.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A massage machine according to the present invention will be described with reference to FIGS. Reference numeral 1 denotes a U-shaped main body case, which is equipped with a kneading roller and a rotating roller between mounting bases 2 and 3 of the main body case 1 facing each other. A portion connecting the mounting bases 2 and 3 of the main body case 1 becomes a handle 4. 5 are legs for installing the main body case on the floor F.

A motor 6 is provided in the mounting base 3. The motor 6 is fixed to the mounting base 3 by the mounting bracket 8 via the rubber 7 for vibration isolation. The driving force of the motor 6 is transmitted to the drive shaft 9 via a reduction gear group. Reference numeral 10 denotes a gear case for housing the reduction gear group, and reference numeral 11 denotes a final reduction gear, which is fixed to the drive shaft 9. 12 is reduction gear 1
No. 1 bearing. Reference numeral 13 denotes a control unit for controlling the motor 6, and 14 denotes a power cord.

The drive shaft 9 is rotatably supported between the mounting bases 2 and 3 by bearings 15 and 15. A pair of rubbing rollers 16, 16 inclined in opposite directions are attached to the center of the drive shaft 9. The rubbing roller 16 is fixed in the rotation direction with respect to the drive shaft 9 and is slidable in the direction of the axis L.
Is constituted by an idler portion 19 rotatably mounted on the outer periphery of the vehicle through a plurality of steel balls 18. The idler portion 19 is composed of a first mounting plate 20 and a second mounting plate 21 having sliding surfaces for the steel balls 18, respectively, and an elastic body such as rubber whose lower end is sandwiched between the mounting plates 20 and 21. It is composed of a massaging unit 22. Reference numeral 23 denotes a screw for fixing the mounting plates 20 and 21 via the lower end of the massaging section 22. A plurality of (about 10) protruding portions 24 protruding inward are formed in the massaging portion 22.

Here, since the sliding surface of the steel ball 18 is not parallel to the axis L of the drive shaft 9 but is inclined, when the drive shaft 9 rotates, the pair of rubbing rollers 16, 16 move away from or approach each other. I do. Therefore, it is possible to massage a massaged part such as a foot sandwiched between the two. The kneading unit 22 rotates integrally with the kneading base 17 when there is no load. However, when a load is applied due to a portion to be massaged being sandwiched or the like, the kneading unit 22 approaches or separates from each other without rotating without receiving a massage. Massage the part.
At this time, the projection 24 presses the massaged site.

In addition, between the pair of rubbing rollers 16,
An auxiliary rotation roller 40 is attached. The auxiliary rotation roller 40 includes an auxiliary rotation roller base 41 fixed to the drive shaft 9 and an auxiliary roller 43 which is a stimulation protrusion rotatably attached to the base 41 by a support shaft 42. . In the example of FIG. 2, the auxiliary roller 43 is provided at a position shifted by 180 degrees in two rotation directions. Each auxiliary roller 43 is deflected in the thrust direction. As can be seen from the figure, the auxiliary rotating roller 40 is
The height of the auxiliary roller from the drive shaft 9 is lower than the height of the tip of the kneading roller 16 from the drive shaft 9 so as to be buried in between.

On the outer side of the pair of rubbing rollers 16, 16 of the drive shaft 9, rotating rollers 25, 25 are attached. The rotating roller 25 has a cylindrical first base 27 fixed to the drive shaft 9 and having a flange 26 at one end and having the other end opened, and a disc-shaped first base 27 that closes an open end at the other end. And a plurality of roller shafts 29 bridged in parallel with the drive shaft 9 between the flange 26 and the second base 28.
And two types of rollers 30 and 31 rotatably attached to the roller shaft 29. One of them 30
Is formed with two stimulation projections 32 having the same shape, and the other is formed with a large stimulation projection 33 on both sides and a flat stimulation projection 34 therebetween. . For example, there are ten roller shafts 29, and the roller 30
And 31 are attached alternately.

The rotation of the drive shaft 9 causes the rotation roller 25 to rotate, and the stimulating projections 32, 33, 34 of the rollers 30, 31.
Massages (rolling massage) a massaged site such as a foot.

The kneading roller 16, the rotating roller 25 and the auxiliary rotating roller 40 are covered with a cloth cover 35. A large number of ribs 36 are formed on the outer periphery of the first base 27 of the rotating roller 25 to prevent the cover 35 from being rolled up during massage.

The pair of rubbing rollers 16 and the rotating roller 2
An elastic body 37 that constantly urges the rubbing rollers 16 in a direction approaching each other is interposed between them. In particular,
A coil spring 37 is provided around the drive shaft 9 with seat plates 38, 3
9 and is wound in a compressed state. The distance between the pair of rubbing rollers 16, 16 is regulated by the rubbing base 17 abutting against the base 41 of the auxiliary rotation roller 40, so that the distance is not reduced any further. That is, the auxiliary rotation roller 40 functions as a spacer.

In this configuration, when the massage massage is not performed between the massage rollers 16 (no load), the pair of massage rollers 16 and 16 are placed in the closest state by the elastic body 37 as shown in FIG.

Next, for example, when the foot is put between the rubbing rollers 16, 16 and the foot is rubbed, a load (load) is applied to the rubbing portion 22, and when the load is increased, the protrusion 24 of the rubbing portion 22 is initially formed. When the load is further increased, the elastic body 37 is compressed, and as shown in FIG.
6 and 16 are retracted away from each other. Therefore, it is possible to prevent an excessive pressure from being applied to the foot that is the massaged site. From this, even a person with a wide foot does not feel pain due to excessive pressure, and can perform a comfortable massage massage.

The part to be massaged inserted between the pair of massaging rollers 16 is subjected to an impact by the auxiliary roller 43 which is a stimulating projection of the auxiliary rotating roller 40, and is simultaneously massaged (rolling massage). For example,
While rubbing both sides of the foot with the rubbing roller 16, the sole of the foot can be massaged simultaneously with the auxiliary roller 43. At this time, the feet are sandwiched between the rubbing rollers 16 and are difficult to escape upward, so that a strong stimulus can be given to the soles.

By placing another foot on the rotating roller 25, stimulation can be given by the stimulating projections 32, 33 and 34 to perform rolling massage.

Here, the stimulating projection 3 of the rotating roller 25 is used.
The number of the auxiliary rollers 43, 34, and the number of the auxiliary rollers 43, which are the stimulating projections of the auxiliary rollers 40, is overwhelmingly smaller in the auxiliary rollers (two in this figure). The stimulus feels stronger, while the stimulus from the rotating roller 25 feels lighter.

In the above embodiment, the stimulating projection 43 of the auxiliary rotating roller 40 is rotatably attached to the base 41,
Although it is configured to be able to rotate while revolving around the drive shaft 9 itself, it may be made to protrude integrally with the base 41 so as not to rotate. This can give a stronger stimulus.

The stimulating projection 4 of the auxiliary rotating roller 40 is also provided.
Although two are provided at positions shifted by 180 degrees, the positions and the numbers are not limited thereto. For example, three may be provided at positions shifted by 120 degrees. Although the projections are shifted in the thrust direction, for example, all the stimulation projections may be provided at the center of the base 41 when viewed in the thrust direction.

When the dimensions of the massage machine of the present invention are verified, the distance W between the left and right rotating rollers 25, which is a substantial effective treatment width, is 300 mm or more, and the maximum diameter H of the rotating roller 25 is It is preferably 130 mm or more. This is because the width of the average adult man and woman sitting on a chair and naturally placing their feet is 300 mm or more.
The reason why H is set to 0 mm or more and H is set to 130 mm or more is to make it possible to massage substantially the entire sole of the foot without moving the foot back and forth simply by placing the foot on the rotating roller. If H is small, only a part of the sole can be massaged, and in order to massage the entire sole, the foot must be moved back and forth. However, this size eliminates the necessity.

[0028]

According to the present invention, a stimulating projection rotated between a pair of rubbing rollers by a drive shaft and having a height from the drive shaft reduced by the height of the tip of the rubbing roller from the drive shaft. Is provided, so that the massage is performed by sandwiching the massaged part between the pair of massage rollers, and at the same time, the massaged part is stimulated by the stimulating protrusion of the auxiliary rotating roller to perform the rolling massage. The rolling massage can be performed on another massaged site by using the stimulating projection of the rotating roller outside the rubbing roller.

If the number of the stimulating projections of the auxiliary rotating roller is smaller than the number of the stimulating projections of the rotating roller located outside the kneading roller, the stimulating projection of the auxiliary rotating roller can be changed to the massaged part. The stimulus given to the massage roller can be made stronger than the stimulus given to the massaged part by the rotating roller located outside the kneading roller, and the strong rolling massage and the light rolling massage can be performed simultaneously.

The stimulation projection of the auxiliary rotating roller can be rotated on the auxiliary rotating roller, or formed integrally with the auxiliary rotating roller base so as not to rotate. It can provide a touch stimulus.

Further, according to the present invention (the invention according to claim 5), when an excessive load is applied from the massaged portion between the pair of rubbing rollers, the pair of rubbing rollers retreats away from each other. In addition, it is possible to prevent an excessive pressure from being applied to the massaged site, and the auxiliary rotating roller acts as a spacer, so that the closest distance between the kneading rollers can be restricted, and the further narrowing of the distance can be prevented.
