DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller-type massager used mainly for stimulating the sole of the foot.

[0002]

2. Description of the Related Art One of the additional therapies for relieving a defect occurring in each part of the body is acupressure, which applies a pressure stimulus to a site where a defect occurs or a specific part of the body corresponding to the defect site, a so-called "pot". Shiatsu is originally an augmentation treatment performed by the fingers of a user, and various massage devices that can easily perform this shiatsu without bothering other persons have been put into practical use. In particular, the sole where the "pot" corresponding to each part of the body is concentrated is considered to be a site where the acupressure is effective, and many massage devices for the purpose of stimulating pressure on the sole have been conventionally proposed.

One type of massager of this type is a roller-type massager in which a plurality of projections for pressing stimulation are provided on the peripheral surface of a roller pivotally supported on one side of a base.
In this massage device, the base is placed on the floor surface with the mounting surface of the roller facing upward, the sole is pressed against the peripheral surface of the roller, and the roller is rotated. It is used by applying a compression stimulus to each part.

[0004]

Such a roller-type massager can change the pressing position by rotating the roller, and can be used in a comfortable posture such as a posture of sitting on a chair. For this reason, in addition to the use in a house, which is a general usage pattern, for example, when the vehicle is brought into the interior of a car, during long-distance driving, during standby time in a traffic jam, the continuation of a sitting posture It may be used for the purpose of recovery from fatigue, change of mood, etc.

However, when used in such a cabin, the floor surface of the cabin, which is the mounting surface of the base, is often not flat, and the rollers rattle during use, giving a good feeling of use. There is a possibility that it will not be obtained, furthermore, while the use of the massager is premised on the use of bare feet, the floor of the cabin where the base is placed is generally Mud, sand, water, and the like brought in from the outside are scattered, and they adhere to the soles during use, resulting in inconvenience.

[0006] The roller of the massage device is generally a resin cylinder integrally formed including a projection on the peripheral surface, and the sole pressed against the peripheral surface of the roller is
It is preferable that the peripheral surface is deformed to some extent in accordance with the shape of the pressed portion in order to keep the pressing feeling good, not flat, and in order to meet this requirement, the roller is made of a soft and highly elastic resin. In such a case, the rotation of the roller is impaired due to the bending of the shaft center accompanying the pressing, and there is a disadvantage that the usability is rather deteriorated.

[0007] In addition, there is a case where the roller is not a simple cylinder but a cylinder having irregularities corresponding to the shape of the sole, but the shape of the sole is not uniform in the longitudinal direction, and the roller is not located at an appropriate position. Even if the irregularities are formed according to the sole shape of the
It is difficult to obtain a good pressing feeling over the whole.

The present invention has been made in view of such circumstances, and can be used on an uneven floor surface, such as a floor surface of a vehicle compartment of an automobile, or on a dirty floor surface. An object of the present invention is to provide a roller-type massager in which a projection on a surface is reliably pressed over the entire sole of the foot and a good feeling of use is obtained.

[0009]

A massager according to the present invention comprises a roller having a plurality of projections on its peripheral surface, which is rotatably supported on one side of a base so as to be rotatable about an axis. In a massage device used by pressing the sole against the peripheral surface and applying a pressure stimulus by the projection to the sole, the engaging means provided on the other surface of the base and the placement of the sole can be performed. And a footrest mat which is fixed to the base by the fixing means.

[0010] In addition, the engaging means is a hook-and-loop fastener for realizing the engaging with the surface fiber of the footrest mat, and the roller includes the protrusion. A molded resin outer cylinder is externally fitted to a metal core, and a spacer is interposed between a part of the core and the outer cylinder to form a predetermined gap therebetween. Each is characterized by having a ring.

[0011] In the present invention, when used on an uneven floor surface or a dirty floor surface, the base is supported by the engaging means provided on the other surface of the base supporting the rollers. Integrate with the footrest mat, placed on the floor via the footrest mat, to prevent the adhesion of dirt from the floor surface,
In addition, the base and the rollers supported by the base are stabilized by contact between the back surface of the footrest mat and the floor surface, thereby realizing a good feeling of use. In addition, a hook-and-loop fastener is used as the engaging means to facilitate attachment and detachment to and from a footrest mat.

[0012] Further, using a roller formed by externally fitting a resin outer cylinder molded including a projection on the peripheral surface to a metal core,
While ensuring that the protrusions are pressed against the soles by the deformation of the outer cylinder, the bending of the rollers due to the pressing is prevented by the rigidity of the core material, so that the rotation of the rollers is not hindered, and a good usability is realized. . Further, a gap is formed by interposing a spacer ring between the core material and the outer cylinder, and the deformation of the outer cylinder within the range of the gap makes it possible to more reliably press the projections over the sole of the foot. To be performed.

The set screws 10, 10 are fixed to the pair of screw protrusions 40, 40 in the width direction projecting toward the base plate by screwing the set screws 10, 10 from the bottom side of the base 1. The base is fitted and fixed to a deep recess formed at a corresponding position on the surface of the base 1.

The support legs 4, 4 at both ends fixed as described above.
Has a support hole that opens in a circular shape on the side facing each of them, and a plate-shaped central support leg 5 has a circular cross section penetrating in the thickness direction at a position matching the support hole. 2 and 3, the roller 2 has a central portion in the axial direction inserted through the through hole of the support leg 5, as shown in FIGS.
Both ends in the axial direction are inserted through the support holes of the support legs 4, 4, and are suspended substantially parallel to the surface of the base 1.

The roller 2 supported as described above is made of a metal such as aluminum, as shown in FIG. 5, and is provided on the outside of a thin-walled cylindrical core member 20 with an outer length slightly shorter than a half length thereof. It is configured by fitting the cylinders 21, 21. The core 20 is inserted into the support holes of the support legs 4 and 4 and the through hole of the support legs 5. The outer cylinders 21 and 21 are connected to the center support leg 5 and the support legs 4 and 4 on both sides. It is fitted between.

The outer cylinder 21 is a cylinder made of a resin having a predetermined elasticity such as an ABS resin, and has a plurality of hemispherical projections 22, 22. It is integrally formed by arranging at appropriate intervals in the direction. Spacers rings 23, 23 of appropriate width are fitted on the core member 20 on both sides of the support portion of the central support leg 5, and the outer cylinders 21, 21 are fitted by using these spacer rings 23, 23. As shown in FIG. 5, between the core member 20 and the outer cylinders 21 and 21 at the center in the longitudinal direction corresponds to the thickness of the spacer rings 23 and 23, as shown in FIG. Is formed.

As shown in FIGS. 4 and 5, on the bottom surface of the base 1, a pair of set screws 10, 10 for fixing the support legs 4, 4 is provided.
The hook-and-loop fasteners 6, 6 are stuck and fixed at positions covering their heads with their engagement surfaces facing outward. These are generally called "magic tapes". As shown in FIG. 1, when the base 1 is placed on the footrest mat 3, it is engaged with the surface fibers of the footrest mat 3. Thus, it acts as an engaging means for integrating the two. The attachment to the surface fibers of the footrest mat 3 can be performed by using a magic tape having a large number of hook-shaped projections on the engagement surface, a so-called male magic tape.

This attachment is firmly maintained with respect to the external force in the direction along the surface of the footrest mat 3 due to the characteristics of the hook-and-loop fasteners 6, 6, but is maintained with respect to the external force in the direction perpendicular to the surface. Can be easily released, and the base 1 and the footrest mat 3 can be detached by a simple operation. As the engaging means, any other means can be used as long as the base 1 and the footrest mat 3 can be integrated. The surface fasteners 6 and 6 are desirably employed because they can withstand repetition.

The massage device according to the present invention, as shown in FIG. 1, places the footrest mat 3 on the floor in a state where the base 1 and the footrest mat 3 are integrated, and 1. The sole is pressed against the peripheral surface of the roller 2 pivotally supported on 1 and the roller 2 is rotated while applying a force to the roller 2 by the sole, so that the peripheral surface, more specifically, the outer cylinders 21 and 21 are rotated. Are used to apply a compression stimulus to each part of the sole by a plurality of projections 22, 22 projecting from the peripheral surface of the foot.

A pair of outer cylinders 21 and 21 externally fitted to the core 20
It enables simultaneous use for the soles of both feet,
As shown by the two-dot chain line in FIG. 1, one foot is used by placing one foot on the footrest mat 3 and pressing the other foot against the outer cylinder 21 on the corresponding side. In order to enable such use, the footrest mat 3 has a plane size on which the sole can be placed, and the base 1 is integrated along one side of the footrest mat 3. It is. The specific plane size of the footrest mat 3 is the side along the base 1
When the base 1 having a width of about 75 mm and a width of about 75 mm is set on the base 1 having a width of about 380 mm and a side orthogonal to 320 mm, the soles of both feet can be mounted on the portion other than the mounting portion.

In such a use state, even if the floor surface on which the footrest mat 3 is placed is dirty, there is a possibility that the stain adheres to the soles placed on the footrest mat 3. It can be used without trouble even on a dirty floor surface such as the interior of a car. At this time, a tangential force for generating the rotation is applied to the roller 2 under the action of the sole pressing force.
Adheres flexibly to the floor surface, and the footrest mat 3 and the base 1 are integrally formed with the surface fasteners 6 and 6 having a high strength against the pressing force and the tangential force by the fastening means 6 and 6. Therefore, even when the floor surface is not flat and there are some irregularities, the backlash of the base 1 and the rollers 2 during use is suppressed, and stable use is possible.

The back surface of the footrest mat 3 is desirably subjected to a slip preventing process such as a spike process in order to suppress slippage between the mat and the floor on which the footrest mat 3 is placed. In addition, the footrest mat 3 is a mat for preventing the muddy soil from falling off on the floor surface in a vehicle cabin in which entry by foot is prohibited.
It can be used as a so-called earth prohibition mat. This use is possible in both the state where the base 1 is attached and the state where the base 1 is removed.

Further, the roller 2 has a metal core 20 and does not easily bend under the action of the pressing force described above. The outer cylinders 21 and 21 to be applied are made of resin, and a gap is secured between the outer cylinders 21 and 21 and the core material 20 by the spacer rings 23 and 23. Can be deformed within the range, and the large number of protrusions 22, 22,... On the peripheral surface of the outer cylinder 21, 21, are reliably pressed against the entire sole. In this way, the reliable rotation of the roller 2 and the pressing of the protrusions 22, 22,... Over the entire sole are simultaneously achieved, and a good feeling of use is obtained.

[0027]

As described in detail above, the massager according to the present invention is provided with the fastening means on the bottom surface of the base supporting the rollers, and is integrated with the footrest mat by the fastening means. It can be used without soiling the sole even on a dirty floor, such as the floor in the interior of an automobile, and even on an uneven floor, the base and the rollers supported by the base are stable and good. A feeling of use is obtained. Further, since the hook-and-loop fastener is used as the engaging means, it can be easily attached to and detached from the footrest mat.

Further, the roller is constituted by externally fitting a resin outer cylinder integrally including a projection for pressing the sole of the foot to a metal core, and further comprising a part of the core. Since the spacer ring is interposed between the outer cylinder and a predetermined gap is secured between them, the bending of the roller due to the pressing of the sole is suppressed by the rigidity of the core material, and the rotation of the roller is not hindered. The present invention is excellent in that the outer cylinder is deformed within the range of the gap, and the protrusion on the peripheral surface of the roller is reliably pressed over the entire surface of the sole, and a good feeling of use is obtained. It has the effect.
