Description

massager

The present invention relates to a massager.

As a massage method for skin beauty, there is known a method called "gua sha", which promotes the flow of blood or lymph by sliding the edge of a spatula or a spoon on the skin, thereby increasing the metabolism of the skin . In this massage method, a plate-shaped massager called a "gua sha board" is sometimes used. In order to be able to massage various parts of the human body, in many cases, the side surface of the scraping plate, that is, the peripheral edge of the scraping plate in the plan view viewed from the thickness direction has a combination of concave parts, convex parts and straight parts. The concave portion has a concavely curved contour in the plan view, the convex portion has a convexly curved contour in the plan view, and the straight portion has a linear contour in the plan view.

Moreover, as a massage method used for the beauty of skin, a method of rolling a roller while being pressed against the skin is also known. For example, Patent Document 1 describes a massage tool having a plate-shaped body and a plurality of rollers rotatably held on the side surface of the body.

【Prior technical literature】 【Patent Literature】

[Patent Document 1] Japanese Design Registration No. 1436400

However, in the massage tool of patent document 1, the rotation axis of the roller is arrange|positioned along the side surface of a scraping board. Therefore, it is difficult to simultaneously press the side surface of the main body and the roller against the skin to perform gua sha and massage by the roller at the same time. That is, in order to use the massage tool of Patent Document 1 to perform gua sha and massage by the roller simultaneously, it is necessary to simultaneously press the roller and the peripheral portion of the roller on the side surface (ie, the peripheral portion) of the main body against the skin.

However, in the massage tool of Patent Document 1, the plurality of rollers are arranged at equal intervals in the concavely curved portion of the side surface of the main body. Moreover, the part between the rollers of the side surface of a main body is located more inward than these rollers. Therefore, when the roller is pressed against the skin, it may be difficult for the side surface of the main body to come into contact with the skin, and there is a concern that the side surface of the main body does not come into contact with the skin in some cases.

As described above, it is difficult for the massage tool of Patent Document 1 to press the roller and the side surface of the main body to the skin at the same time, so it is difficult to perform scraping and massage by the roller at the same time.

Moreover, when the massaging tool of patent document 1 is to massage the site|part with comparatively large fluctuation|variation, such as a face, for example, it may become difficult to press a roller against the skin.

An object of the present invention is to provide a massager which can perform scraping and massage by a rotating body at the same time, and which can easily press the rotating body to a site with relatively large fluctuations.

Hereinafter, means for solving the above-mentioned problems and their effects will be described.

A massager for solving the above-mentioned problems has: a main body having a plate shape for performing massage by sliding the peripheral edge of the main body on the skin; The peripheral portion of the main body protrudes outward, and the rotation axis of the rotating body extends outward through the peripheral portion of the main body.

According to this structure, a massager has a rotating body, and this rotating body is arrange|positioned so that it may protrude outward from the side surface of a main body, ie, the peripheral edge part in the plan view seen from the thickness direction. Further, the rotation axis of the rotating body extends outward through the peripheral edge portion of the main body. By arranging the rotating body and the rotation axis in this way, the peripheral edge part of the main body and the rotating body can be pressed to the skin at the same time. As a result, scraping and massage by the rotating body can be performed simultaneously. In addition, by arranging the rotating body so as to protrude outward from the peripheral edge portion of the main body, the rotating body can also be easily pressed to a portion with a large fluctuation such as a face.

According to the present invention, scraping and massage by the rotating body can be performed simultaneously, and the rotating body can be easily pressed to a site with large fluctuations.

The main body of the massager embodying the present invention has a plate shape. The massager is configured to be able to scrape by sliding its side on the skin. That is, a massager is comprised so that scraping can be performed by sliding the peripheral edge part in planar view seen from the thickness direction on the skin. Here, the plate-like shape includes a flat plate-like shape and a shape obtained by bending at least a part of a flat plate to such an extent that it is considered to be a plate in a normal sense. For example, the surface of the part surrounded by the peripheral part in the main body may be flat, or may be slightly bulged or slightly recessed in the thickness direction. Moreover, you may provide unevenness|corrugation on the surface of this part. In addition, the "thickness direction" refers to a direction perpendicular to the plane having the largest projected area of the main body.

The shape of the main body in the plan view viewed from the thickness direction, that is, in the plan view in which the projected area of the main body is maximized, is not particularly limited, and various forms can be employed. For example, the shape of the main body in the plan view may be a basic shape such as a circle, an ellipse, and an oval, or a polygonal shape such as a triangle, a square, a rectangle, and a pentagon.

In addition, the main body may have a shape obtained by deforming the above-mentioned relatively simple shape to such an extent that it can be recognized as the shape in a normal sense. In addition to the above-described relatively simple shape, the main body may have a relatively complex shape in which the outline in the plan view is composed of a combination of straight lines and curved lines, such as a heart shape or a comma symbol.

The massager has at least one rotatable rotating body arranged so as to protrude outward from the peripheral edge portion of the main body. The rotation axis of the rotating body extends outward through the peripheral edge portion of the main body. Ideally, the main body has at least one bulging portion bulging outward in a plan view viewed from the thickness direction thereof, and the rotating body is disposed so as to protrude outward from the bulging portion. Here, the above-mentioned bulging part includes, for example, a heart-shaped head, a comma-shaped head, a quadrangular corner, and the like, which can be regarded as a part that bulges outward than the periphery in a normal sense.

By arranging the rotating body so as to protrude outward from the bulging part, when the rotating body is pressed to the skin, the part connected to the bulging part can be easily pressed to the skin together with the rotating body. As a result, the usability of the massager can be further improved. In addition, in this case, the rotating body can also be easily pressed against the surface of the skin even at a site recessed from the surrounding, such as the eye area and the bridge of the nose. As a result, the massage by the rotating body can be performed uniformly.

In addition, the main body may have: two bulging parts arranged side by side with each other; Wait until the bulging part is more concave inward. In this case, the recessed portion, that is, a portion protruding outward from the periphery, such as the lower jaw, is sandwiched between the two bulging portions, and the entire recessed portion can be easily pressed to the surface of the portion. As a result, it is possible to perform scraping uniformly in the part protruding outward than the periphery. In addition, in this case, the massager can be reciprocated by sandwiching a portion protruding outward than the periphery in the recessed portion, and pressing the rotating body against the skin, so that gua sha and massage by the rotating body can be performed at the same time. massage.

Ideally, the peripheral edge portion of the main body in a plan view viewed from the thickness direction of the main body has at least one convex portion whose outline is convexly curved, and has at least one of the following at least one concave portion and at least one straight portion : The concave portion has a concavely curved outline in the plan view and is connected to the convex portion, and the straight portion has a straight outline in the plan view and is connected to the convex portion. Ideally, the rotation axis of the rotating body extends outward through the convex portion. That is, ideally, the rotating body is disposed so as to protrude outward from the convex portion connected to either the concave portion or the straight portion.

When the convex part on which the rotating body is arranged is connected to other convex parts, when the rotating body is pressed against the skin, the above-mentioned convex part is arranged so as to be farther away from the skin as the rotating body is separated. Therefore, in this case, when the rotating body is pressed against the skin, the length of the convex portion that can simultaneously contact the skin tends to be relatively short.

On the other hand, when the straight portion or the concave portion is connected to the convex portion on which the rotating body is disposed, the straight portion is more difficult than when the straight portion is connected to the convex portion on which the rotating body is disposed, compared to the case where the straight portion is connected to the convex portion on which the rotating body is disposed. Or the recessed part is arrange|positioned in the position close|similar to the skin. Therefore, in this case, the rotating body and the above-mentioned concave portion or linear portion can be simultaneously pressed against the skin, and thus the length of the main body can be further extended compared to the case where the rotating body and the convex portion are simultaneously pressed against the skin. The length of the contact portion between the peripheral edge and the skin. As a result, scraping can be performed more efficiently.

Furthermore, it is desirable that the peripheral portion of the main body has a convex portion and a concave portion connected to the convex portion, and the rotating body is disposed so as to protrude outward from the convex portion. When gua sha and massage by a rotating body are performed simultaneously, the surface image of the part to be gua sha, for example, the cheeks and the lower jaw, is often a convex curved surface. Therefore, by providing the concave portion adjacent to the convex portion on which the rotating body is arranged, the concave portion is arranged so that the concave portion follows the convex curved surface of the skin when the rotating body is pressed against the skin. As a result, while pressing the rotating body against the skin, the concave portion can be pressed along the curved shape of the skin. Thereby, the length of the contact part of the peripheral edge part of a main body and skin can be lengthened further, and scraping can be performed more efficiently.

In addition, it is desirable that the peripheral portion of the main body has a concave portion or a straight portion and a convex portion connected to both ends of the concave portion or the straight portion in at least a part thereof, and the rotating body is arranged such that at least a part of the concave portion or the straight portion is connected. It protrudes more outward than the straight line tangent to both these convex-shaped parts. In this case, when the concave portion or the linear portion is pressed against the skin, the rotating body can be made to protrude toward the skin side. Therefore, the linear portion or the concave portion can be pressed against the skin, and the rotating body can be pressed against the skin more easily. Accordingly, the usability of the massager can be further improved.

At least one rotating body is arranged so as to protrude outward from the side surface of the main body, that is, the peripheral edge portion of the main body in a plan view viewed from the thickness direction. The entire rotating body may be arranged so as to protrude from the peripheral edge portion of the main body, or a part of the rotating body may be arranged so as to protrude from the peripheral edge portion of the main body. As long as at least a part of the rotating body is disposed so as to protrude from the peripheral edge portion of the main body, the peripheral edge portion of the main body and the rotating body can be simultaneously pressed against the skin.

The rotating body may be spherical or cylindrical, for example. Here, the spherical shape includes a true sphere, an ellipsoid, a teardrop shape, or the like, which is a shape obtained by deforming a true sphere to such an extent that it is considered to be spherical in a normal sense. In addition, the cylindrical shape includes a cylinder such as a cylinder and a square cylinder; and, for example, a tapered shape, that is, a shape in which the diameter becomes smaller as it approaches the tip, or an inverted tapered shape, that is, a shape with a larger diameter as it approaches the tip, etc. It is a shape obtained by deforming a cylinder to such an extent that it is considered to be cylindrical.

The outer diameter of the rotating body is not particularly limited, but in the case of, for example, a spherical rotating body, the diameter in the direction orthogonal to the rotation axis can be appropriately set, for example, within a range of 10 to 20 mm. Moreover, in the case of a spherical rotating body, it is desirable to make the said diameter in the range of 15-20 mm. By making the diameter of the spherical rotating body within the above-mentioned specific range, the rotating body can be pressed to the surface of the skin more easily even in a region recessed from the surrounding, such as the eye circumference or the bridge of the nose. From this viewpoint, the above-mentioned diameter is more preferably in the range of 18 to 19 mm.

In addition, in the case of a cylindrical rotating body, for example, the diameter in the direction orthogonal to the rotation axis can be appropriately set within a range of 10 to 20 mm, and the diameter along the rotation axis can be appropriately set within a range of 10 to 25 mm. length in the direction.

The surface of the rotating body may be formed of a curved surface, or may be formed of a plurality of flat surfaces such as a triangular-shaped flat surface or a quadrangular-shaped flat surface. From the viewpoint of further enhancing the massage effect on the skin, it is preferable that the surface of the rotating body is constituted by a plurality of flat surfaces. In addition, from the same viewpoint, it is preferable to provide a plurality of protrusions on the surface of the rotating body.

Ideally, the body of revolution is spherical. In this case, the rotating body can also be easily pressed against the surface of the skin even in a site recessed from the surrounding, such as the eye area and the bridge of the nose. As a result, the massage by the rotating body can be performed uniformly.

The rotation axis of the rotating body is a straight line extending outward through the peripheral edge portion of the main body. For example, the axis of rotation may be arranged so as to pass through the center of gravity of the rotating body, or may be arranged so as not to pass through the center of gravity of the rotating body. In addition, the rotation axis may extend in a direction orthogonal to the thickness direction of the main body, that is, in a direction parallel to the plane with the largest projected area of the main body, or may extend in a direction inclined with respect to the thickness direction of the main body.

The angle formed by the thickness direction of the main body and the extending direction of the rotation axis can be appropriately set, for example, within a range of 60 to 120 degrees. According to this, the peripheral part of the main body and the rotating body can be simultaneously pressed against the skin, and the rotating body can be rotated with the movement of the massager.

In addition, ideally, the angle formed by the thickness direction of the main body and the extension direction of the rotation axis is in the range of 75 to 105 degrees, preferably in the range of 80 to 100 degrees, and even more preferably in the range of 85 to 95 degrees, In the range of 88~92 degrees, it is especially good. As the angle formed by the thickness direction of the main body and the extending direction of the rotation axis is closer to 90 degrees, the rotating body can be rotated more smoothly.

Moreover, it is desirable for the said massager to have two rotating bodies arrange|positioned at a space|interval outside a main body, and the rotation axis of these two rotating bodies is arrange|positioned so that the space|interval may become wide as it goes to the outside from the main body. In this case, by pressing the two rotating bodies against the skin and reciprocating the massager on the skin, it is possible to massage and lift the skin by these rotating bodies. In addition, by using the above-mentioned massager, the user can select and perform a desired massage from scraping, massage in which the rotating body rolls on the skin, massage in which scraping and rolling of the rotating body are simultaneously performed, and the above-mentioned massage for lifting the skin. massage.

In the above-mentioned case, the interval between the rotating bodies can be appropriately set according to the shape and diameter of the rotating bodies. For example, when the rotating body has a spherical shape with a diameter of 10 to 20 mm, the distance between the rotating bodies is preferably set within a range of 7 mm or more and less than 10 mm. Thereby, the skin can be pulled moderately and strongly by the two rotating bodies, and the massage effect can be further improved. In addition, it is desirable that the angle formed by the rotation axes is set within a range of, for example, 40 to 70 degrees. Even in this case, the skin can be pulled moderately and strongly by the two rotating bodies, and the massage effect can be further enhanced. From the viewpoint of further enhancing the massage effect, it is more preferable that the interval between the rotating bodies be 7.5 mm or more and 9 mm or less. Likewise, the angle formed by the rotation axes is preferably 45 to 65 degrees, and more preferably 50 to 60 degrees.

Moreover, in the above-mentioned case, the massager may further have one or more rotating bodies independently of the two rotating bodies for pulling up the skin.

In the above case, the angle formed by the thickness direction of the main body and the extending direction of the rotation axis is ideally in the range of 60 to 120 degrees, more preferably in the range of 75 to 105 degrees, and even more preferably in the range of 80 to 100 degrees. It is better to be in the range of 85~95 degrees, and it is even better to be in the range of 88 to 92 degrees.

In the case of performing the massage to lift the skin, the two rotating bodies are pressed against the skin as described above, and the massager is reciprocated on the skin. When massage is performed by this method, the magnitude of the force that pulls up the skin changes according to the angle formed by the traveling direction of the massager and the extending direction of the rotation axis. Therefore, when the difference between the angle formed by the traveling direction on the forward path and the extending direction of the rotation axis and the angle on the return path is large, the difference between the force pulling the skin on the forward path and the force on the return path is large. As a result, the skin-lifting power of either one of the forward path or the return path may be weaker than the skin-lifting power of the other.

By making the angle formed by the thickness direction of the main body and the extension direction of the rotation axis close to 90 degrees, the difference between the angle formed by the advancing direction on the forward path and the extension direction of the rotation axis and the angle formed on the return path can be easily reduced. Therefore, the same degree of massage effect can be obtained on the forward path and the return path by a simple operation such as reciprocating the massager. As a result, the usability of the massager can be further improved.

In the above-mentioned case, ideally, the two rotating bodies are arranged side by side along the outline of the main body in a plan view viewed from the thickness direction. In the case of performing a skin-lifting massage using two rotating bodies, as described above, the two rotating bodies are pressed against the skin and the massager is reciprocated in the direction orthogonal to the arrangement direction of the two rotating bodies That's it.

Conventionally, as a beauty device that lifts the skin by two rotating bodies, for example, a beauty device described in Japanese Patent Application Laid-Open No. 2015-186540 is known. The beauty device has a rod-shaped handle and two rotating bodies arranged at the top of the handle. In this beauty device, when the two rotating bodies are pressed against the skin, the longitudinal direction of the handle is substantially orthogonal to the arrangement direction of the two rotating bodies. Therefore, in the case of using this beauty device to perform a massage to lift the skin, it is necessary to move the entire arm and to reciprocate the beauty device in the longitudinal direction of the handle.

On the other hand, when the two rotating bodies are arranged side by side along the outline of the main body as described above, when these rotating bodies are pressed against the skin, the angle formed by the thickness direction of the main body and the arrangement direction of the two rotating bodies is approximately vertical.

Therefore, for example, when performing a skin-lifting massage on the part along the cheekbones or the part above the shoulders, such as the eye area, the rotating body should be rotated in such a position that the hand holding the massager is up and the elbow is down. Press it against the skin, swing the forearm and the wrist from side to side, and reciprocate the massager in the thickness direction. In addition, for example, when performing a skin-lifting massage on a part below the shoulders, such as the abdomen or the wrist, as long as the forearm is in a horizontal position, the rotating body is pressed against the skin, and the forearm or wrist is swung up and down to massage. It is sufficient to reciprocate the tool in the thickness direction.

As described above, according to the massager described above, the forearm and the wrist are moved in a swinging manner without moving the upper arm, so that the skin-lifting massage can be performed. As a result, the load on the arm portion at the time of the massage to lift the skin can be further reduced, and the usability of the massager can be further improved.

The massager has two vertices, an intersection where the rotational axes of the two rotating bodies intersect each other, and a rear end point that is a point on the outer surface of the main body having the largest distance from the intersection. The vertex of one of the two vertices is a point at which the outer surface of the rotating body of one of the two rotating bodies intersects the above-mentioned rotation axis of the rotating body, and the vertex of the other of the two vertices is The point at which the outer surface of the rotating body of the other of the two rotating bodies intersects the above-mentioned rotation axis of the rotating body. Ideally, the vertex with the shorter distance from the back end point among the two vertices is called the first vertex, and the vertex with the longer distance from the back end point among the two vertices is called the second vertex. When the vertex, the direction parallel to the straight line connecting the second vertex and the rear end point is referred to as the vertical direction, and the direction perpendicular to the straight line in the plan view viewed from the thickness direction of the main body is referred to as the lateral direction , the outer dimension of the main body in the longitudinal direction is longer than the outer dimension of the main body in the transverse direction.

Here, the external dimensions in the longitudinal direction and the external dimensions in the lateral direction are the dimensions measured as follows. First, in a plan view viewed from the thickness direction, that is, a plan view viewed so that the projected area of the main body is maximized, a quadrilateral formed by longitudinally extending sides and laterally extending sides and circumscribing the main body is determined. The length in the vertical direction of the quadrilateral is referred to as the external dimension in the vertical direction, and the length in the horizontal direction is referred to as the external dimension in the horizontal direction.

In the case of performing a massage that rolls the rotating body on the skin or a massage that lifts the skin, the user can hold the main body from the opposite side of the rotating body and press the rotating body against the skin, so that the skin can be moderately increased. Press pressure. In this case, the distance from the hand to the rotating body can be shortened compared with the case where the shape of the main body is elongated in the vertical direction as described above. As a result, when performing the above-mentioned massage, the skin can be pressed moderately strongly, the massager can be easily moved as desired, and the usability of the massager can be further improved.

In a plan view viewed from the thickness direction, the main body may have two regions divided by a center line that is the main body on a cross-section perpendicular to a straight line connecting the second vertex and the rear end point. A line formed by connecting the centroids. In other words, the center line is a line extending through the centroid of the main body on the cross-section perpendicular to the straight line connecting the second vertex and the rear end. In this case, the two rotating bodies are arranged outside the same area of the two areas. Here, the centroid of the main body refers to the center of the region surrounded by the outline of the main body in the above-mentioned cross section.

In this case, when performing a massage that rolls the rotating body on the skin or a massage that lifts the skin, the user can hold the main body from the opposite side of the rotating body and press the rotating body to the skin, so that the size can be appropriately increased. pressure on the skin. Moreover, by arranging the rotating body at the above-mentioned specific position, the wrist can hold the main body in a straight and natural posture, and the rotating body can be pressed against the skin. As a result, the usability of the massager can be further improved.

The main body may have a tapered shape in which the width becomes narrower in a plan view viewed from the thickness direction from the second vertex side toward the rear end point. In this case, the shape of the main body can be more easily grasped by the user. As a result, the usability of the massager can be further improved.

Ideally, the massager has: a first electrode disposed on the periphery of the main body, a second electrode disposed on the surface of the rotating body, and a third electrode disposed in the main body at a position separated from the first electrode, the above-mentioned The massager is configured to be able to form a current path including the electrode in contact with the skin in a state in which at least one of the first electrode and the second electrode and the third electrode are in contact with the skin.

In this case, by holding the main body by hand so as to be in contact with the third electrode, pressing at least one of the first electrode and the second electrode against the skin, and performing massage such as scraping, a weak current can be made to flow through the above current path. In addition to massage such as scraping, by flowing the above-mentioned weak current through the massaged part, the massage effect and the effect by the weak current can be doubled, and the cosmetic effect on the skin can be further improved.

The weak current flowing through the skin is not particularly limited. For example, the magnitude of the current can be appropriately set within a range of 50 to 1000 μA. In addition, the waveform of the current may be a direct current, or an alternating current such as a sine wave, a rectangular wave, and a triangular wave. In addition, the current can also be a pulse current composed of one pulse or a plurality of pulse groups. By appropriately selecting the magnitude and waveform of the current from these ranges, for example, a weak current called microcurrent for improving skin metabolism, and ions for permeating charged cosmetic ingredients from the skin surface to the inside of the skin can be used. The ion-extraction current for introducing electric current to float charged dirt components such as pore dirt to the surface of the skin flows through the skin.

Three convex portions 211c.

In other words, the first convex portion 211 a is arranged at a position closer to the right than the upper end 221 of the first top portion 22 in the peripheral portion 21 of the main body 2 . The outline of the first convex portion 211 a in a plan view viewed from the thickness direction of the main body 2 is a convex shape that swells rightward from the upper end 221 of the first top portion 22 downward and then retreats leftward.

The first concave portion 212a is connected to the lower end 214 of the first convex portion 211a. The first concave portion 212 a is arranged in a range from the first top portion 22 to the tail portion 24 in the peripheral edge portion 21 of the main body 2 . The outline of the first concave portion 212a in the plan view is a concave shape that retreats to the left as it goes downward from the lower end 214 of the first convex portion 211a, and then bulges to the right.

The second convex portion 211b is connected to the upper end of the first convex portion 211a. Specifically, the second convex portion 211b is arranged at a leftward position than the upper end 221 of the first top portion 22 in the peripheral edge portion 21 of the main body 2 . The outline of the second convex portion 211 b in the above plan view extends from the upper end 221 of the first top portion 22 toward the space between the first top portion 22 and the second top portion 23 . In the outline of the second convex portion 211b in the plan view, the middle portion between the upper end 221 of the first top portion 22 and the left end 215 of the second convex portion 211b is slightly convex outward.

The second concave portion 212b is arranged between the first top portion 22 and the second top portion 23 . The outline of the second concave portion 212b in the plan view is a concave shape that is concave downward as it goes to the left from the left end 215 of the second convex portion 211b, and then protrudes upward.

The third convex portion 211 c constitutes the remaining portion of the peripheral edge portion 21 of the main body 2 . That is, the third convex portion 211c constitutes a portion of the peripheral edge portion 21 from the portion corresponding to the second top portion 23 to the tail portion 24 via the left portion of the peripheral edge portion 21 . The outline of the third convex portion 211c in the plan view is convexly curved over the entire range.

Moreover, the main body 2 has the main surface part 28 on the inner side of the peripheral edge part 21 in the plan view seen from the thickness direction. The main surface portion 28 has a plurality of raised portions 280 extending from the tail portion 24 toward the top portions 22 and 23 . The plurality of protuberances 280 have a curved shape curved along the outline of the main body 2 in a plan view viewed from the thickness direction. In addition, although not shown in the drawings, each of the raised portions 280 has an arc-shaped profile in a cross-section in the width direction.

The massager 1 of Example 1 has the two rotating bodies 3 (3a, 3b) arrange|positioned at the outer side of the 1st top part 22 in the main body 2 at intervals. The rotation axis 31 ( 31 a , 31 b ) of each rotating body 3 ( 3 a, 3 b ) extends through the center of gravity of the rotating body 3 . In addition, the rotation axes 31 of the two rotating bodies 3 extend so that the distance from each other becomes larger as they extend outward from the main body 2 , and as shown in FIGS. 2 and 4 , they cross each other at an intersection 312 . Hereinafter, for convenience, among the two rotating bodies 3, the rotating body close to the first concave portion 212a is referred to as the first rotating body 3a, and the rotating body close to the second concave portion 212b is called the second rotating body 3b.

The interval between the rotating bodies 3 in Example 1, that is, the minimum value of the distance between the surface of the first rotating body 3a and the surface of the second rotating body 3b can be appropriately set, for example, within a range of 7 to 10 mm. In addition, the angle θ formed by the rotation axes 31 of the rotating body 3 can be appropriately set within a range of 40 to 70 degrees. In the massager 1 of Example 1, the interval between the rotating bodies 3 was 8.3 mm, and the angle θ formed by the rotation axes 31 of the rotating bodies 3 was 53 degrees.

As shown in FIG. 2 , the first rotating body 3a is arranged so as to be farther from the straight line L1 tangent to both the lower portions of the first convex portion 211a and the third convex portion 211c (that is, the peripheral portion of the tail portion 24). Outward prominence. In addition, the second rotating body 3b is arranged further outward than the straight line L2 tangent to both the upper portion of the second convex portion 211b and the third convex portion 211c (ie, the peripheral portion of the second top portion 23). protrude.

In this way, the peripheral edge part 21 of the main body 2 in the massager 1 has at least a part of the two convex-shaped parts 211 and the concave-shaped part 212 arranged between the convex-shaped parts 211 . Moreover, each rotating body 3 is arrange|positioned so that at least a part may protrude more outward than the straight lines L1 and L2 tangent to both of these two convex-shaped parts 211.

In addition, as shown in FIGS. 5 and 6 , the rotation axis 31 of each rotating body 3 extends in a direction perpendicular to the thickness direction of the main body 2 . That is, as shown in FIG. 6 , the angle θ2 formed by the extending direction of the rotation axis 31 in each rotating body 3 and the straight line T parallel to the thickness direction of the main body 2 is 90 degrees.

As shown in FIGS. 1 to 5 , each rotating body 3 has a spherical shape. More specifically, as shown in FIGS. 1 and 2 , the rotating body 3 has a shape obtained by cutting out a pointed portion of the teardrop shape. That is, a half of the distal end side of the rotary body 3 is hemispherical, and the outer diameter gradually decreases from the hemispherical portion toward the main body 2 compared with the case where the rotary body 3 is completely spherical. The diameter of the rotating body 3 , that is, the maximum value of the outer diameter of the rotating body 3 in the direction orthogonal to the rotation axis 31 can be appropriately set, for example, within a range of 10 to 20 mm. The surface of the rotating body 3 is composed of a plurality of triangular flat surfaces. The second electrode 42 described later is provided on the surface of the rotating body 3 .

The massager 1 of Example 1 includes a first electrode 41 arranged on the peripheral edge portion 21 of the main body 2 , a second electrode 42 arranged on the surface of the rotating body 3 , and a position in the main body 2 that is separated from the first electrode 41 . the third electrode 43 . Moreover, the massager 1 is comprised so that the electric current path containing the electrode which contacts the skin can be formed in the state in which at least one of the 1st electrode 41 and the 2nd electrode 42 and the 3rd electrode 43 contact the skin.

More specifically, the first electrode 41 is provided at the first concave portion 212 a in the peripheral portion 21 of the main body 2 , that is, the first electrode 41 is provided at the connection connecting the first top portion 22 and the tail portion 24 having the rotating body 3 . part whole. In addition, the third electrode 43 is provided at a portion closer to the inner side than the peripheral edge portion 21 of the main body 2 in a plan view viewed from the thickness direction. The first electrode 41 , the second electrode 42 , and the third electrode 43 are connected to each other via a not-shown control circuit built in the main body 2 . Further, the control circuit is connected to the solar cell element 44 arranged between the second top portion 23 and the tail portion 24 in the peripheral portion 21 of the main body 2 .

The massager 1 of Example 1 can be used in various forms. For example, when lifting the cheeks and the eye area, as shown in FIG. 8 , the first concave portion 212a of the main body 2 is pressed to the cheek along the nasolabial line, and the first rotating body 3a is pressed to the eye area. Further, by reciprocating the massager 1 to the left and right along the cheeks (see arrow M1 in FIG. 8 ), the first concave portion 212a can be slid along the bulge of the cheeks, and the first rotating body 3a can be Roll around the eyes. According to this, as shown in FIG. 9 , it is possible to perform scraping on the cheek 511 with relatively thick skin to promote blood flow. In addition, the rotating body 3 can be rolled on the eye area 512 where the skin is relatively thin at the same time as the scraping, and the eye area can be stretched by applying soft stimulation like massage by a beautician. As a result, the cheeks can be lifted up.

In addition, as another method for lifting the cheeks and the eye area, for example, as shown in FIG. 10 , the tops 22 and 23 are directed toward the mouth, the tails 24 are directed obliquely downward from the tops 22 and 23, and the first concave portion is 212a is pressed to the cheek and the first rotating body 3a is pressed to the eye circumference. Next, by reciprocating the massager 1 so that the first rotating body 3a is rotated around the tail portion 24 (see arrow M2 in FIG. 10 ), the first concave portion 212a can be caused to follow the bulge of the cheek. While sliding is performed, the first rotating body 3a is rolled along the cheekbones. According to this, as shown in FIG. 11 , it is possible to perform scraping on the cheek 521 with relatively thick skin to promote blood flow. In addition, simultaneously with scraping, the rotating body 3 can be rolled on the part 522 along the cheekbones where the skin is relatively thin, and the part can be stretched by applying soft stimulation like massage by a beautician. As a result, the cheeks can be lifted up.

In addition, in the case of tightening the lower jaw, for example, as shown in FIG. 12 , the main body 2 is positioned with the lower jaw sandwiched between the first top portion 22 and the second top portion 23 with the second rotating body 3 b facing the mouth side. and the second rotating body 3b is pressed against the face. Next, by reciprocating the massager 1 along the lower jaw (see arrow M3 in FIG. 12 ), the recessed portion 25 between the first top portion 22 and the second top portion 23 , that is, the recessed portion 25 in the peripheral portion 21 of the main body 2 can be The portion from the upper end 221 of the first top portion 22 to the upper end 231 of the second top portion 23 is slid along the lower jaw, while the second rotating body 3b is rolled along the edge of the mouth. According to this, as shown in FIG. 13 , it is possible to apply gua sha to the portion 531 along the lower jaw where the skin is relatively thick to promote blood flow. In addition, simultaneously with scraping, the rotating body 3 can be rolled on the lips 532 where the skin is relatively thin, and this part can be stretched by applying soft stimulation like massage by a beautician. As a result, the lower jaw can be tightened.

As described above, the massager 1 can perform a method of scraping alone, or a method of performing massage by the rotating body 3 alone, in addition to the method of pressing the peripheral edge 21 of the main body 2 and the rotating body 3 against the skin at the same time to massage. method. For example, when scraping is performed alone, although not shown in the drawings, the massager 1 can be reciprocated by pressing the second top portion 23 or the tail portion 24 of the main body 2 against the skin to reciprocate the subject. 2 The pressed part applies moderate stimulation to promote blood flow.

In addition, in the case of performing the massage by the rotating body 3 alone, as shown in FIG. 14, for example, by pressing the first rotating body 3a to the eye circumference, the massager 1 is reciprocated left and right (see FIG. 14). Arrow M4 ), as shown in FIG. 15 , the portion 54 along the eye circumference where the skin is relatively thin can be stretched by applying soft stimulation like massage by a beautician. Moreover, instead of the method of rolling the first rotating body 3a on the skin as shown in FIG. 14 , the same effect can be achieved by rolling the second rotating body 3b on the skin.

Although not shown in the figure, the massage by the revolving body 3 is not limited to the above-mentioned eye area. For example, massage by the revolving body 3 can be performed on the part along the cheekbones and the part with relatively thin skin such as the mouth.

The massager 1 of Example 1 can also perform the massage that lifts the skin between the two rotating bodies 3 by pressing both the first rotating body 3 a and the second rotating body 3 b to the skin and moving back and forth. For example, when performing massage to lift the skin around the eyes, as shown in FIG. 16 , the first rotating body 3 a and the second rotating body 3 b are aligned in the up-down direction, and these rotating bodies 3 are pressed against the eye circumference. . In addition, by reciprocating the massager 1 along the eye circumference in this state (see arrow M5 in FIG. 16 ), the skin 55 (see FIG. 17 ) around the eye can be lifted and blood flow can be promoted.

In addition, in the case of performing a massage to lift the skin of the eye end, as shown in FIG. 18 , the first rotating body 3 a and the second rotating body 3 b are aligned in the left-right direction, and these rotating bodies 3 are pressed against the eye circumference. . Next, by reciprocating the massager 1 along the line from the end of the eye to the temple in this state (see arrow M6 in FIG. 18 ), the skin 56 at the end of the eye (see FIG. 19 ) can be lifted to promote blood flow .

Although it is not shown in the figure, the massage for lifting the skin by the two rotating bodies 3 is not limited to the above-mentioned eye area or the end of the eye. Massage the part of the bone or the thin part of the skin such as the mouth.

Thus, the massager 1 is comprised so that various types of massage can be performed by suitably changing the pressing method with respect to the skin.

When a weak current flows through the skin by the massager 1, the body 2 is held so that the third electrode 43 is in contact with the hand, and at least one of the rotating body 3 and the first concave portion 212a is brought into contact with the skin touch. Accordingly, a current path including at least one of the first electrode 41 and the second electrode 42 and the third electrode 43 is formed. Moreover, when light is irradiated to the solar cell element 44, electric power can be supplied to a control circuit, and a weak current can be made to flow through a current path. As a result of the above, a weak current can be made to flow through the skin.

Next, the effect of the massager 1 of Example 1 is demonstrated. As shown in FIG. 2, the massager 1 has the rotating body 3, and the rotating body 3 is arrange|positioned so that it may protrude outward from the peripheral part 21 of the main body 2. As shown in FIG. Further, the rotation axis 31 of the rotating body 3 extends outward through the peripheral edge portion 21 of the main body 2 . By arranging the rotating body 3 and the rotation axis 31 in this way, the peripheral edge portion 21 of the main body 2 and the rotating body 3 can be pressed against the skin at the same time. As a result, scraping and massage by the rotating body can be performed simultaneously. In addition, by arranging the rotating body so as to protrude outward from the peripheral edge portion 21 of the main body 2, the rotating body can also be easily pressed against a portion with large fluctuations such as the face, for example.

Further, as shown in FIG. 2 , the main body 2 has a tail portion 24 , and a first top portion 22 and a second top portion 23 that are bulging portions 20 bulging outward in a plan view viewed from the thickness direction of the main body 2 . Further, the rotation axis 31 of the rotating body 3 extends outward through the first top portion 22 serving as the bulging portion 20 . Therefore, when the first rotating body 3a is pressed against the skin as shown in, for example, FIGS. 8 and 10 , the first rotating body 3a and the first concave portion 212a connected to the first top portion 22 can be easily pressed. to the skin. In addition, when the second rotating body 3b is pressed against the skin as shown in FIG. 12, for example, the first top portion 22, the second concave portion 212b connected to the first top portion 22, and the second top portion 23 can be easily Press firmly into the skin. Therefore, the usability of the massager 1 can be further improved. In addition, by arranging the rotating body 3 so as to protrude outward from the bulging portion 20 , the rotating body 3 can be easily pressed against the surface of the skin even at a site recessed from the surrounding, such as the eye circumference or the bridge of the nose. As a result, the massage by the rotating body 3 can be performed uniformly.

Moreover, as shown in FIG. 2, as the bulging part 20, the main body 2 has the 1st top part 22 and the 2nd top part 23 mutually arrange|positioned in parallel. Furthermore, the main body 2 has a recessed portion 25 formed between the first top portion 22 and the second top portion 23 . The recessed portion 25 is recessed further inward than the top portions 22 and 23 in a plan view viewed from the thickness direction of the main body 2 . Therefore, for example, as shown in FIG. 12 , a portion protruding outward from the periphery, such as the lower jaw, can be sandwiched between the recessed portion 25 , and the entire recessed portion 25 can be easily pressed against the surface of the portion. As a result, it is possible to perform scraping uniformly at the portion protruding outward from the periphery. In addition, in this case, by sandwiching a portion protruding outward from the periphery in the recessed portion 25, and pressing the rotary body 3 against the skin to reciprocate the massager 1, it is possible to perform both scraping and rotation at the same time. Body 3 massage.

As shown in FIG. 2 , the peripheral part 21 of the main body 2 has a convex part 211 and a concave part 212 connected to the convex part 211 , and the rotating body 3 is arranged so as to protrude outward from the convex part 211 . Therefore, for example, as shown in FIGS. 8 and 10 , the rotating body 3 can be pressed against the skin, and the concave portion 212 can be pressed along the curved shape of the skin 5 .

For example, in the case of lifting the cheeks (see FIG. 8 ), as shown in FIG. 20 , the first rotating body 3 a is brought into contact with the eye circumference 512 and the first concave portion 212 a is brought into contact with the cheeks 511 . Get a massage. At this time, since the first concave portion 212 a is curved along the convex curved surface of the cheek 511 , the first concave portion 212 a can be pressed along the cheek 511 .

On the other hand, in FIG. 21, the massager 9 is shown, and the massager 9 has the convex part 911, the two rotating bodies 91 respectively protruding from this convex part 911, and the convex part 912 connected to the convex part 911. The convex portion 912 is curved so as to be away from the convex curved surface of the cheek 511 . Therefore, when the massager 9 is used to perform scraping and massage by the rotating body 91 at the same time, the distance from the skin to the convex portion 912 is easier than that of the massager 1 (see FIG. 20 ) of the first embodiment. get bigger. 20 and FIG. 21, the skin 5 including the cheeks 511 and the eye area 512 is indicated by a dashed-dotted line.

In this way, in the massager 1, since the convex portion 211 and the concave portion 212 are arranged as described above, the length of the contact portion between the peripheral edge portion 21 of the main body 2 and the skin can be further increased, and as a result, the scraping can be performed more efficiently. .

Moreover, as shown in FIG. 2, the peripheral part 21 of the main body 2 has two convex parts 211 and the concave part 212 arrange|positioned between these convex parts 211 in at least a part. Moreover, the rotating body 3 is arrange|positioned so that at least a part may protrude more outward than the straight line tangent to both of these two convex-shaped parts 211. Therefore, for example, as shown in FIGS. 8 and 10 , when the concave portion 212 or the convex portion 211 is pressed against the skin, the rotating body 3 can be made to protrude toward the skin side. Therefore, the straight portion or the concave portion 212 can be pressed against the skin, and the rotating body 3 can be pressed against the skin more easily. Thereby, the usability of the massager 1 can be further improved.

The rotating body 3 has a spherical shape as shown in FIG. 2 . Therefore, for example, as shown in FIGS. 8 , 10 and 14 , the rotating body 3 can be easily pressed against the surface of the skin even in a portion recessed from the periphery, such as around the eyes or the bridge of the nose. As a result, the massage by the rotating body 3 can be performed uniformly.

As shown in FIG. 5 , the angle formed by the thickness direction of the main body 2 and the extending direction of the rotation axis 31 is in the range of 60 to 120 degrees. Therefore, for example, as shown in FIGS. 8 to 12 , the peripheral portion 21 of the main body 2 and the rotating body 3 can be simultaneously pressed against the skin, and the rotating body 3 can be rotated with the movement of the massager 1 .

In addition, the two rotating bodies 3 are arranged side by side along the outline of the main body 2 in a plan view viewed from the thickness direction. In other words, as shown in FIG. 4 , the massager 1 of Embodiment 1 has: two vertexes 311 ( 311 a , 311 b ); an intersection 312 ; and a rear end 241 . The vertex ( 311 a ) of one of the two vertices 311 is the point where the outer surface of the rotating body ( 3 a ) of one of the two rotating bodies 3 intersects the rotation axis ( 31 a ) of the rotating body ( 3 a ). The vertex ( 311 b ) of the other of the two vertices 311 is the point at which the outer surface of the rotating body ( 3 b ) of the other of the two rotating bodies 3 intersects the rotation axis ( 31 a ) of the rotating body ( 3 b ). . The intersection 312 is the intersection of the two rotation axes 31 (31a, 31b) with each other. The rear end point 241 is the point in the outer surface of the main body 2 at which the distance from the intersection point 312 is the largest.

In addition, among the vertices 311 ( 311 a , 311 b ) of the two points, the vertex with a short distance from the rear end point 241 (ie, the vertex of the first rotating body 3 a ) is referred to as the first vertex 311 a , and the vertex from the rear end point 241 is referred to as the first vertex 311 a . The vertex with the longer distance (that is, the vertex of the second rotating body 3b) is called the second vertex 311b. As shown in FIG. 7, the first vertex 311a, the second vertex 311b and the rear end point 241 are arranged on a straight line , and when the massager 1 is viewed so that the distance from the second vertex 311 b to the rear end point 241 is the largest, the first vertex 311 a is arranged between the second vertex 311 b and the rear end point 241 . In addition, in FIG. 7, the surface shape of the rotating body 3 is simplified for convenience, but in reality, as shown in FIGS. 1-5, the surface of the rotating body 3 is constituted by a plurality of triangular planes.

For example, as shown in FIG. 16 or FIG. 18 , the massager 1 of Embodiment 1 can be rotated by two rotations by pressing the two rotating bodies 3 against the skin and reciprocating the massager 1 in the thickness direction of the main body 2 . Body 3 moderately and strongly lifts the skin. In addition, the above-mentioned reciprocating movement can be easily realized by, for example, moving the massager 1 by swinging the forearm or the wrist without moving the upper arm.

In contrast, FIG. 22 shows a conventional cosmetic device 902 having a rod-shaped handle 92 and two rotating bodies 91 provided at the tip of the handle 92 . In such a cosmetic device 902, when the two rotating bodies 91 are pressed against the skin, the longitudinal direction of the handle 92 and the arrangement direction of the two rotating bodies 91 are substantially orthogonal to each other. Therefore, in the case of using this beauty device to perform a massage to lift the skin, as indicated by arrow M7, the entire arm must be moved to reciprocate the beauty device 902 in the longitudinal direction of the handle 92. Therefore, compared with the massager 1 of Example 1, the load to an arm becomes high easily.

In addition, in the conventional beauty device 902, for example, as shown in FIG. 23, there is a method of reciprocating the beauty device 902 by holding the handle 92 like a pen to swing the forearm or the wrist. However, in this method, it is not easy to adjust the intensity of the massage to the skin. For example, compared with the case where the massager 1 of Example 1 holds the main body 2 from the opposite side of the rotating body 3, the force with which the rotating body 91 presses the skin tends to become weaker. Therefore, the power to lift the skin may become weaker.

In this way, according to the massager 1 of the first embodiment, compared with the conventional beauty device 902, the intensity of massage can be easily adjusted. In addition, the load on the arm at the time of massaging can be further reduced, and the usability can be further improved.

Moreover, in the massager 1 of Example 1, as shown in FIG. 4, the direction parallel to the straight line L3 connecting the second vertex 311b and the rear end point 241 is referred to as the vertical direction X, and it is viewed from the thickness direction of the main body 2 When the direction perpendicular to the straight line L3 in the obtained plan view is called the lateral direction Y, the outer dimension DX of the main body in the vertical direction X is longer than the outer dimension DY of the main body 2 in the lateral direction Y.

Therefore, for example, as shown in FIG. 14 or FIG. 16 , when the user holds the main body 2 from the opposite side of the rotating body 3 , that is, from the left side in the width direction, and presses the rotating body 3 against the skin, it is possible to appropriately increase the resistance to the rotating body 3 . The pressure of the skin. Moreover, by making the shape of the main body 2 long in the vertical direction as described above, the distance from the hand to the rotating body 3 can be shortened compared with the case where the shape is long in the horizontal direction.

Therefore, according to the massager 1 of Example 1, when performing the massage which rolls the rotating body 3 on the skin or the massage which lifts the skin, it is easy to press the skin moderately strongly and move the massager 1 as desired. As a result, the usability of the massager 1 can be further improved.

Moreover, in the massager 1 of Example 1, as shown in FIG. 4, the direction parallel to the straight line L3 is called the vertical direction X, and the straight line L3 is a straight line connecting the second vertex 311b and the rear end point 241. In addition, the direction orthogonal to the straight line L3 in the plan view seen from the thickness direction of the main body 2 is referred to as the lateral direction Y. In this case, the outer dimension DX of the main body 2 in the longitudinal direction X is longer than the outer dimension DY of the main body 2 in the lateral direction Y.

Therefore, for example, as shown in FIGS. 14 and 16 , when the user holds the main body 2 from the opposite side of the rotating body 3 , that is, from the left side in the width direction, and presses the rotating body 3 against the skin, the pressing force on the skin can be reduced. The pressure is moderately increased. Furthermore, by making the shape of the main body 2 to be elongated in the vertical direction as described above, the distance from the hand to the rotating body 3 can be shortened compared with the case of making the shape of the main body 2 elongated in the lateral direction.

Therefore, according to the massager 1 of the first embodiment, when performing the massage in which the rotating body 3 rolls on the skin or the massage in which the skin is pulled up, the massager 1 can be easily moved as desired while pressing the skin moderately strongly. . As a result, the usability of the massager 1 can be further improved.

Further, as shown in FIG. 4 , the main body 2 has two regions A1 and A2 divided by a center line L4 which is the main body 2 on a cross-section perpendicular to the straight line L3 in a plan view viewed from the thickness direction. A line formed by connecting the centroids of , the straight line L3 connects the second vertex 311 b and the rear end point 241 . In other words, the center line L4 is a line extending through the centroid of the main body 2 in a section perpendicular to the straight line L3. The two rotating bodies 3 are arranged outside the same area A1 of the two areas A1 and A2.

Therefore, for example, as shown in FIG. 14 or FIG. 16 , when performing a massage for rolling the rotating body 3 on the skin or a massage for pulling the skin, the user holds the main body 2 from the opposite side of the rotating body 3 and rotates it. The body 3 is pressed against the skin, and the pressing force on the skin can be increased moderately. Moreover, by arranging the rotating body 3 at the above-mentioned specific position, the body 2 can be held in a natural posture in which the wrist is straight, and the rotating body 3 can be pressed against the skin. As a result, the usability of the massager 1 can be further improved.

The main body 2 has a tapered shape in which the width becomes narrower in a plan view viewed from the thickness direction from the second vertex 311b side toward the rear end point 241 . Therefore, the shape of the main body 2 can be more easily grasped by the user. As a result, the usability of the massager 1 can be further improved.

As shown in FIG. 2, the massager 1 has the two rotating bodies 3, and the two rotating bodies 3 are arrange|positioned at intervals outside the main body 2. As shown in FIG. The rotation axes 31 of the rotating bodies 3 extend so as to be closer to the rotating body 3 , the distance from each other becomes larger. Therefore, for example, as shown in FIG. 16 and FIG. 18 , by pressing the two rotating bodies 3 against the skin and reciprocating the massager 1 on the skin, the skin can be massaged by these rotating bodies 3 to lift the skin . In addition, by using the massager 1 described above, the user can select from scraping, massage in which the rotating body 3 rolls on the skin, massage in which scraping and rolling of the rotating body 3 are simultaneously performed, and the above-mentioned massage for lifting the skin perform the desired massage.

As shown in FIG. 2 , the massager 1 includes a first electrode 41 arranged on the peripheral portion 21 of the main body 2 , a second electrode 42 arranged on the surface of the rotating body 3 , and the first electrode 41 arranged in the main body 2 . The third electrode 43 in the separated position. The massager 1 is configured to be able to form a current path including an electrode in contact with the skin in a state in which at least one of the first electrode 41 and the second electrode 42 and the third electrode 43 are in contact with the skin.

Therefore, by holding the main body 2 by hand so as to be in contact with the third electrode 43 and pressing at least one of the first electrode 41 and the second electrode 42 to the skin to perform massage such as scraping, a weak current can be generated flow through the above current path. In addition to massage such as scraping, by flowing the above-mentioned weak current through the massaged part, the massage effect and the effect by the weak current can be doubled, and the cosmetic effect on the skin can be further improved.
