Beauty roller

The present invention relates to a beauty roller that rolls on the skin surface and performs beauty, and particularly relates to a beauty roller characterized by the rotation mechanism of the roller portion.

A variety of beauty rollers have been known. While holding the beauty roller body by hand, the user contacts the skin with a rotatable roller part to perform beauty on the face, arms, legs, and the like. For example, in the cosmetic roller disclosed in Patent Document 1, the handle portion gripped by the user is divided into two forks, and a roller portion for contacting the face and body is attached to each end portion. The roller part is an elongated sphere, and the surface has a triangular lattice shape. The roller portion is a sphere having an elliptical cross section, and a rotation axis is provided at a position passing through the center of the cross section.

The cosmetic device disclosed in Patent Document 2 includes a handle and a roller rotatably supported by the handle. Conductive portions are provided on the outer peripheral surface of the handle and the outer peripheral surface of the roller, and the conductive portions are electrically insulated from each other. A permanent magnet as a power generation unit that generates power in accordance with the rotation of the roller and a supply unit that supplies the generated power between the conductive parts of the roller are provided inside the roller. The cosmetic device disclosed in Patent Document 3 has the same shape.

The massage device disclosed in Patent Document 4 has a configuration in which a spherical roller is provided at the tip of the handle portion, and a plurality of hemispherical protrusions are provided on the surface of the sphere. The roller is supported by a rotation axis that passes through the center of the sphere.

On the other hand, in a conventionally known massager, a configuration in which a roller is vibrated to enhance the massage effect is well known. For example, a roller incorporated in a massage chair is generally one that vibrates when driven by a motor with a rotational axis decentered from the center of the roller.

Further, the roller massager disclosed in Patent Document 5 includes a vibration device in which an eccentric weight is fixed to a drive shaft of a motor in a massager having a shape in which a user holds the main body.
In the beauty tool disclosed in Patent Document 6, a vibration generator is built in the roller. When the roller is applied to the neck and the roller is moved along the neck so as to stretch the skin of the neck, the roller moves while rotating, and the vibration generated by the vibration generator is applied to the neck. ing.

As in each of these documents, a configuration in which a vibration device is provided to give vibration when a massager gripped by a user is rotated by a motor or the like is known. However, the incorporation of a motor and a vibration device has problems such as a complicated device and a need for a power source for vibration.

The present invention was created in view of the above-described problems of the prior art, and in a beauty roller that rolls the roller portion on the skin surface while the user grips it with a hand, an appropriate vibration is applied to the skin surface. It aims at providing the technique which aims at the improvement of a massage effect by giving or adjusting the angle which a roller part contact | abuts.

In order to solve the above problems, the present invention provides the following beauty roller.
In other words, in a beauty roller that performs beauty by contacting and rotating the roller body against the skin surface, it has a shaft support portion that supports the rotation axes of the two roller bodies in the vicinity of the end portion, and can grip the outer circumference in the longitudinal direction. A substantially rod-shaped main body portion formed in the above, two rotating shafts of a roller body projecting in a direction different from the longitudinal direction of the main body portion by a predetermined opening angle, and two rollers rotatable by these rotating shafts In the configuration including the body, the center position in the cross section perpendicular to the axial direction of the rotation shaft and the position of the rotation shaft are arranged eccentrically at least partially.

In the cosmetic roller, the rotation shaft and the central axis of the roller body may be arranged to be inclined.

The rotation shaft of the cosmetic roller includes an angle variation mechanism that can vary the opening angle from the longitudinal direction of the main body within a predetermined range, and in the angle variation mechanism, an urging means that urges the body in the longitudinal closing direction. The structure provided may be sufficient.

The roller body of the cosmetic roller may have a configuration in which a bowl-shaped uneven surface substantially parallel to the rotation axis is formed on the outer peripheral surface thereof.
Moreover, the structure which has the shape of the said cross section which distribute | arranged the rounded corner | angular part uniformly on the outer periphery may be sufficient as a roller body.

The two roller bodies of the beauty roller may have electrode portions, respectively, so that the skin surface can be energized between the electrodes.

The present invention has the following effects by the above configuration.
First, with respect to the two rotatable roller bodies, the center position in the cross section perpendicular to the axial direction of the rotation axis and the position of the rotation axis are arranged eccentrically at least partially, so that As the roller rolls, vibration is transmitted from the roller body, contributing to the improvement of the beauty effect. Since vibration naturally occurs with rolling as in the prior art, a driving device such as a vibration device or a motor is not required, and a power source is also unnecessary.

In the case where the rotation axis and the central axis of the roller body are arranged to be inclined, a twisting motion is generated in the vibration of the roller body, so that a more complex sense can be given to the skin surface.
For example, by rolling an eccentric roller to the skin surface, a twisting motion acts on the skin surface, and a sense different from normal vibration can be generated such that the skin is pulled up.

The rotating shaft of the beauty roller includes an angle changing mechanism capable of changing the opening angle from the longitudinal direction of the main body part within a predetermined range, and in the angle changing mechanism, biasing means for biasing in the closing direction in the longitudinal direction By providing, the opening angle of a roller body can be changed according to the contact | abutted site | part. For example, in the case of a narrow part such as an arm, the roller body can be opened and contacted in a wide range in the case where the opening angle is closed, or in the case of the stomach or thigh.

In the roller body of the present invention, by forming a bowl-shaped uneven surface substantially parallel to the rotation axis on the outer peripheral surface thereof, the uneven surface gives a slight vibration to the skin surface during rotation, and by the vibration of the rotation shaft The strength of the contact force of the roller body changes, and the bodily sensation can be complemented.
In particular, when the roller body has a cross-sectional shape in which a plurality of rounded corners are evenly arranged on the outer periphery, it is possible to realize good skin stimulation.

By having an electrode part on the roller body and energizing the skin surface, electrical muscle stimulation can be given and the beauty effect can be further enhanced.

The perspective view of the beauty roller which concerns on this invention. Explanatory drawing of the opening / closing mechanism of a roller body. Explanatory drawing which shows the opening / closing aspect of a roller body. Sectional drawing which shows the rotating shaft part of a roller body. Explanatory drawing which shows the shape of another Example of a roller body.

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. The embodiment is not limited to the following.
FIG. 1 is a perspective view of a beauty roller (1) according to the present invention. Near the end of the substantially rod-shaped main body (10), there are provided shaft support portions (11) and (12) for supporting the rotation shafts of the two roller bodies (20) and (21). The user rolls the roller body (20) (21) while contacting the face, arms, legs, etc. while holding the outer periphery of the main body (10).

As shown in the figure, the roller bodies (20) and (21) are formed with bowl-shaped uneven surfaces (200) and (201) in parallel with the direction of the rotation axis, and this rolls on the skin surface. Thus, beauty is performed by the warm feeling and tactile sensation of the metal material, the vibration caused by the uneven surfaces (200) and (201), and the pressure when the roller bodies (20) and (21) are brought into contact with each other.
As is well known, a semiconductor chip may be arranged on the roller bodies (20) and (21) so that the skin surface can be beauty-treated.

FIG. 2 is an explanatory diagram of the opening / closing mechanism of the roller body. The two roller bodies (20) and (21) are pivotally supported by the respective mechanisms of the pivot support portions (11) and (12) disposed on the main body portion (10) side.
By the way, in the conventional beauty roller, the rotating shaft of the roller body was fixed, and the roller body and the main body were configured to be relatively rotatable.

On the other hand, in the present invention, the rotary shafts (110) and (120) are not fixed to the main body (10), but the open / close pivot pins (111) and (121) are arranged at the roots in the main body (10). The opening / closing pivot pins (111) and (121) pivotally support the shaft fixing portions (112) and (122) of the rotating shaft. Thereby, the rotational axis (110) (120) of the beauty roller realizes an angle variation mechanism that can vary the opening angle from the longitudinal direction of the main body (10) within a predetermined range.

Further, as shown in FIG. 2 (b), this angle variation mechanism is provided with torsion springs (113) and (123) as biasing means for biasing in the closing direction in the longitudinal direction (D1). One end (113a) (123a) of the torsion spring is connected to the rotating shaft (110) (120), and the other end is connected to the main body (10). In FIG. It is urging | biasing in the direction (D2) which opens to the outer side of a direction, ie, closes a roller body (20) (21) to a longitudinal direction side.

FIG. 3 is an explanatory view showing an opening / closing mode of the roller body. In this embodiment, in the natural state, the angle formed by the roller bodies (20) and (21) is about 60 degrees, and is stabilized in the closed state by the action of the torsion springs (113) and (123).

When the user rolls with the neck and thighs sandwiched between the roller bodies (20) and (21), the roller bodies (20) and (21) act on the torsion springs (113) and (123) by the pressure. Open against power. A constant pressure can be applied to the skin surface by appropriately adjusting the strength of the torsion springs (113) and (123).
In this embodiment, the angle formed by the roller bodies (20) and (21) in the most open state is about 110 degrees. This angle can be arbitrarily changed, but the opening / closing angle in the angle changing mechanism is preferably in the range of approximately 45 degrees to 135 degrees.

Next, the structure which decenters the rotating shaft of a roller body as the characteristic of this invention is described. FIG. 4 is a cross-sectional view showing a rotating shaft portion of the roller body.
As described above, the rotating shaft (110) protruding from the shaft fixing portion (112) of the main body (10) is fitted into the roller body (20), and the roller body (20) via the bearing (201). Is pivotable.

At this time, the axial direction (L1) of the rotating shaft (110) is not arranged on the central axis of the roller body (20), but is inclined with respect to the axial direction (L2) of the central axis. Normally, by matching the central axis with the rotation axis, the outer periphery of the roller body (20) rotates at a fixed position during rotation. Also in the conventional beauty roller, the central axis and the rotation axis coincide with each other, and the skin surface is stimulated by the unevenness of the surface of the roller body.

In the present invention, since the central axis and the rotation axis are inclined, if the roller body 20 is rolled, a twisting motion occurs in the roller body (20), and the portion of the outer peripheral surface that contacts the skin surface changes every moment. It is possible to give the user a totally different feel from the rolling of the monotonous roller body.
The configuration of the present invention contributes to easy handling and weight reduction of the beauty roller because the roller body naturally vibrates irregularly as the user rolls without using a vibration device or a drive device. To do.

As described above, if the outer periphery of the roller body (20) is provided with the ridge-shaped uneven surfaces (200) (201) parallel to the rotation axis, the roller body (20) can be divided by the number of ridges during one rotation. Vibration can be applied to the skin surface, and one large twist can be applied during one rotation. Stimulation on the skin surface in the beauty roller is an extremely important function, and the present invention exhibits a characteristic behavior that could not be realized by the conventional beauty roller. For example, since a large twist produces an effect of pulling up the skin, it is possible to enhance the massage effect on the skin and muscles where sagging is a concern.

In this embodiment, the axial direction of the rotating shaft and the central axis of the roller body are inclined. However, the central position in the cross section perpendicular to the axial direction of the rotating shaft and the position of the rotating shaft are at least partially. The effect of this invention can be show | played by arrange | positioning eccentrically.
For example, a configuration in which the axial direction of the rotating shaft and the central axis are parallel and the position is eccentric may be employed.

FIG. 5 is an explanatory view showing the shape of another embodiment of the roller body. In another embodiment, a roller body (20 ') having a rounded corner (20a) (20b) (20c) is provided as shown in the AA sectional view of FIG. 5 (b).

Also in this alternative embodiment, the rotating shaft (110) passes through a position decentered from the center (centroid) of the cross section, resulting in a complicated behavior. That is, when rolling on the skin surface, the corners (20a), (20b), and (20c) are pressed strongly, so that the stimulation occurs three times and the distance from the rotation axis (110) to the outer periphery is short (20c ) The combination of two stimuli to the periphery and the periphery of the corner (20a) (20b) having a long distance is combined.

Furthermore, a more complex massage effect can be realized by a combination with an angle variation mechanism that varies the opening angle of the roller body in the present invention. While the torsion spring (113) exerts an elastic force on the skin surface, an eccentric motion of the roller body can give a completely different feel to the conventional beauty roller during rolling.

The shape of the roller body is not limited to the above rounded triangle, and can be any rounded polygonal shape up to about a rounded octagon.
Moreover, the structure which makes a roller body substantially cylindrical shape and inclines the center axis | shaft and a rotating shaft may be sufficient.

In the above embodiment, a simple configuration that does not use a power source has been described. However, an EMS function may be provided that applies electrical muscle stimulation (EMS) by energizing skin and muscle using two roller bodies as electrodes. .
That is, a power source such as a battery or a power supply circuit and an EMS control circuit are built in the main body (10), and are connected to two metal roller bodies. For example, the EMS function can be turned on / off by a switch attached to the main body (10).

According to the present invention, the two roller bodies change on the skin surface according to the shape of the skin surface or roll on the skin surface while applying vibration, so that the massage effect of EMS is obtained simultaneously with the stimulation by the roller body. be able to.
Furthermore, the structure which generate | occur | produces the timing which gives electrical stimulation with the rotation angle of the said roller body may be sufficient. For example, if an electrode in the middle of connection with the main body is provided on a part of the outer periphery of the rotating shaft (110) and energization is performed according to the rotation angle of the rotating shaft, the rotation of the roller body and the generation of EMS stimulation are prevented. Can be synchronized.

In this configuration, the entire roller body is used as an electrode, but an electrode may be provided on a part of the roller body. For example, the structure which forms an electrode only in the front-end | tip part of a roller body, or a side part may be sufficient.
The energization from the electrode may be a low-frequency or high-frequency current. In addition, the function of a known cosmetic device can be appropriately provided.
