Description

Beauty machine

The present invention relates to a cosmetic device.

Conventionally, various beauty instruments that exert a massage effect by pressing the skin with a roller have been proposed. As an example of such a cosmetic device, Patent Document 1 discloses a handle having a pair of rollers attached to a distal end portion of a handle having a bifurcated distal end portion. Such a cosmetic device reciprocates in a state where a pair of rollers are in contact with the skin, so that the skin is picked up together with the pressing of the skin and has a massage effect.

JP2013-103086A

Although the application range of the cosmetic device disclosed in Patent Document 1 covers a wide range such as the face and arms, it is difficult to sufficiently pick up narrow skin such as the eyes and mouth. Therefore, there is room for improvement to fully massage these parts.

The present invention has been made in view of such a background, and an object thereof is to provide a cosmetic device suitable for massaging a narrow portion such as an eye or a mouth.

One aspect of the present invention includes a handle,
The handle is supported at the first end of the handle so as to be rotatable about the respective axis lines, and the axis is a second end opposite to the first end with respect to the center line of the handle. A plurality of rollers including a pair of rollers disposed so as to be inclined in a direction from the portion toward the first end,
With
In the cosmetic device, the diameter of the pair of rollers is 15 to 20 mm, and the shortest distance between the outer peripheral surfaces of the pair of rollers is 7 mm or more and less than 8 mm.

In the cosmetic device, both the diameter of the pair of rollers is 15 to 20 mm (first condition) and the shortest distance between the outer peripheral surfaces of the pair of rollers is 7 mm or more and less than 8 mm (second condition). Is satisfied, the pair of rollers can surely pick up the skin in a narrow part such as the eyes and the mouth so as not to be excessive, and can be pressed effectively. As a result, these parts can be massaged sufficiently. That is, the massage effect of the part is exhibited to the maximum only when both the first condition and the second condition are satisfied.

As described above, according to the present invention, it is possible to provide a cosmetic device suitable for massaging a narrow portion such as the eyes and mouth.

FIG. 3 is a front view of a cosmetic device according to the first embodiment. The right view of the cosmetics device in Example 1. FIG. The rear view of the cosmetics device in Example 1. FIG. 1 is an exploded perspective view of a cosmetic device in Embodiment 1. FIG. The VV line position sectional drawing in FIG. The perspective view seen from the normal line direction of the plane containing both the axial lines of a pair of roller in Example 1. FIG. The front view which shows the use condition of the cosmetics device in Example 1. FIG.

In the cosmetic device, the first condition is that the diameter of the pair of rollers is 15 to 20 mm, but the diameter of the pair of rollers is preferably 18 to 19 mm. Thereby, when the said 2nd condition is comprised, the picking up effect of the skin of narrow parts, such as an eye area and a mouth, is played moderately, and the massage effect improves further.

When the diameter of the roller is smaller than 15 mm, the range of the skin where the pressing effect and the picking up effect can be manifested becomes excessively narrow. Therefore, in this case, even if the second condition is satisfied, a massage effect in a narrow portion such as the eyes and the mouth cannot be sufficiently obtained.

On the other hand, when the diameter of the roller is larger than 20 mm, since the size of the roller is relatively large with respect to a narrow part such as an eye or a mouth, it is difficult to press and pick these parts. Therefore, in this case, even if the second condition is satisfied, it is difficult to massage these parts pinpoint.

In the cosmetic device, the second condition is that the shortest distance between the outer peripheral surfaces of the pair of rollers is 7 mm or more and less than 8 mm. Thereby, when the first condition is satisfied, the distance between the outer peripheral surfaces of the pair of rollers is not too wide or too narrow, and the distance is in an optimum range for picking up a narrow portion such as the eyes and mouth. It becomes. As a result, these parts are picked up effectively.

When the shortest distance between the outer peripheral surfaces of the pair of rollers is less than 7 mm, the picking effect acts too strongly on the skin. Therefore, in this case, even if the first condition is satisfied, it is not suitable for use in sensitive parts such as the eyes and mouth.

On the other hand, when the shortest distance between the outer peripheral surfaces of the pair of rollers is 8 mm or more, even if the first condition is satisfied, the skin of a narrow part such as the eyes and mouth is picked up pinpointed. It becomes difficult. Therefore, it is difficult to massage these parts pinpoint.

It is preferable that the angle formed by the axis of the pair of rollers, that is, the opening angle of the pair of rollers is 70 to 80 °. As a result, when the first condition and the second condition are satisfied, the effect of picking up the skin in a narrow part such as the eyes and the mouth can be appropriately achieved by bringing the cosmetic device into contact with the skin and reciprocating. Is done. As a result, the massage effect is more effectively achieved.

When the opening angle of the pair of rollers is less than 70 °, the picking effect on the skin tends to act too strongly. Therefore, in this case, even if the first condition and the second condition are satisfied, it is not suitable for use in sensitive parts such as the eyes and mouth.

On the other hand, when the opening angle of the pair of rollers exceeds 80 °, even if the first condition and the second condition are satisfied, the skin of a narrow part such as the eyes and mouth is pinpointed. It becomes difficult to pick up. Therefore, it is difficult to massage these parts pinpoint.

More preferably, the angle formed by the axis of the pair of rollers, ie, the opening angle of the pair of rollers is 74 to 76 °. Thereby, in the case where the first condition and the second condition are satisfied, the effect of picking up the skin of a narrow part such as the eyes and the mouth is more appropriately exhibited, and thus the massage effect is more effectively achieved. The

It is preferable that an angle formed by the center line of the handle and the axis when viewed from the direction in which the axes of the pair of rollers overlap with each other is 90 ° to 155 °. In this case, when used on the face such as the eyes and mouth, the axis of the pair of rollers is appropriately inclined with respect to the skin surface while the handle is gripped. The effect of picking up the skin is effectively achieved by rotating. As a result, the massage effect is improved. Moreover, since the reciprocating operation of the cosmetic device can be performed without raising the elbow or bending the wrist excessively, the operability is excellent.

When the angle formed between the axis of the handle and the axis when viewed from the direction in which the axes of the pair of rollers overlap each other is greater than 155 °, when used on the face, Since the roller axis is excessively inclined, it is difficult to smoothly rotate the pair of rollers. This increases the friction between the roller and the skin surface, increasing the burden on the skin surface. And in order to reduce this burden, since it is necessary to twist the wrist holding the handle largely and maintain the inclination of the axis of the pair of rollers with respect to the skin surface, the operability is poor.

If the angle between the axis of the handle and the axis when viewed from the direction in which the axes of the pair of rollers overlap each other is less than 90 °, the inclination of the axes of the pair of rollers relative to the skin surface when used If the first end of the handle on which the pair of rollers are provided touches the skin surface, the skin may be burdened, which is not preferable.

The handle is preferably formed in a straight line from the first end to the second end. Thereby, when using it for a face such as the eyes or the mouth, the angle at which the roller contacts the skin surface can be easily adjusted, so that the operability is improved. In addition, the entire beauty device can be compactly formed while maintaining the ease of gripping the handle, making it suitable for carrying around on a trip.

The cosmetic device may include other rollers in addition to the pair of rollers. The other roller may be the same roller as the pair of rollers, or may be a roller having a different mode. For example, the cosmetic device may include two pairs of the pair of rollers, and may include a total of four rollers.

Inside the roller core 29, a holder-engaging groove 29a with which the roller engaging claw 26a of the bearing holder 26 is engaged is formed. The roller 20a is attached to the bearing holder 26 by engaging the roller engaging claw 26a with the holder-engaging groove 29a. Thereby, the roller 20a is attached to the branch portion 11a of the first end portion 11 so as to be rotatable about the axis L1 of the roller shaft 22.
As shown in FIG. 4, the roller 20b is also attached to the branch portion 11b of the first end portion 11 so as to be rotatable about the axis L2 of the roller shaft 22 with the same configuration as the roller 20a. It has been.

As shown in FIG. 6, the diameter of the pair of rollers 20 (20a, 20b) can be 15 to 20 mm, and in this example is 18 mm. And the shortest distance W between the outer

peripheral surfaces

21a and 21b of a pair of roller 20 (20a, 20b) can be 7 mm or more and less than 8 mm, and is 7 mm in this example. Furthermore, the angle β formed by the two axes L1 and L2 of the pair of rollers 20 (20a and 20b) can be set to 70 to 80 °, and in this example is 74.5 °. Note that an angle β formed by the axes L1 and L2 is an angle formed by the two viewed from the normal direction IV (see FIG. 2) of the plane including the axes L1 and L2.

Further, as shown in FIG. 2, the axes L1 and L2 are on the Y1 side in the direction from the second end 12 opposite to the first end 11 to the first end 11 with respect to the center line L of the handle 10. Inclined. As shown in FIG. 2, the angle (side projection angle) α formed between the center line L0 and the axis L2 (L1) when viewed from the direction in which the axes of the pair of rollers overlap each other is 90 to 155 °. In this example, it is 120 °.

As shown in FIG. 1, a window portion 13 a is formed near the first end portion 11 in the center portion on the front side of the handle 10. On the other hand, as shown in FIG. 4, a concave portion 15 is formed in the central portion on the back side of the handle 10, and the concave portion 15 communicates with the window portion 13a. And the lens 30 is inserted in the window part 13a from the back side. A solar cell panel 31 is disposed on the back side of the lens 30. Two terminals 32 are connected to the solar cell panel 31.

A lens cover 33 is provided on the back side of the solar cell panel 31. The lens cover 33 is formed with two holes 33a, and the terminal 32 is also formed with a hole 32a. The screw 34 is inserted into the

holes

33 a and 32 a and fastened to the boss 15 a in the recess 15. Accordingly, the lens 30, the solar cell panel 31, the terminal 32, and the lens cover 33 are fixed to the handle body 13 with the solar cell panel 31 interposed between the lens 30 and the lens cover 33. The above-described shaft support 33b is formed on one end side of the lens cover 33 (on the first end portion 11 side of the handle main body 13). The shaft holder 36 is attached to the shaft support 33b through a hole 33a on one end side of the lens cover 33 and a screw 34.

The recess 15 is covered with a handle cover 14. The handle cover 14 is provided with an engaging claw 14a, and the handle cover 14 is fixed to the handle main body 13 by engaging the engaging claw 14a with an engaging groove (not shown) in the recess 15. An O-ring 35 a is interposed between the lens 30 and the handle body 13, and an O-ring 35 b is interposed between the handle cover 14 and the handle body 13.

The solar cell panel 31 is electrically connected via a terminal 32 to the handle body 13 that is provided with conductive chrome plating. Further, the solar cell panel 31 includes a pair of rollers 20 (20a, 20b) plated with conductive platinum through a shaft holder 36 made of a conductive material, a roller shaft 22,

bearings

27a, 27b, and a bearing holder 26. Is electrically connected. Thereby, when the cosmetic device 1 is used, the outer peripheral surface 21a of the roller 20 comes into contact with the skin, whereby the roller 20 and the handle 10 are electrically connected via the human body. And when the solar cell panel 31 receives light through the lens 30 of the window part 14 and generates electric power, a weak current flows between the outer peripheral surface 21a of the roller 20 and the skin. As a result, the stimulation to the skin increases and the massage effect is further enhanced.

Next, the usage mode of the cosmetic device 1 will be described.
When the cosmetic device 1 is used, as shown in FIG. 7, the user presses the outer

peripheral surfaces

21a and 21b of the pair of rollers 20 against the skin surface 50 in a narrow part such as the eyes and mouth while holding the handle 10. When the cosmetic device 1 is moved in the direction of the first end portion 11 (the direction of the arrow P1 in FIG. 6) while being in contact with the roller, the

rollers

20a and 20b are rotated in the direction of the arrow P2 about the axes L1 and L2, respectively. . At this time, a pressing force is applied to the skin surface by the

rollers

20a and 20b. After the cosmetic device 1 is moved in the direction P1, the cosmetic device 1 is moved in the direction of the second end portion 12 (in the direction of the arrow Q1 in FIG. 6) so as to return to the original position. Rotated. As a result, as shown in FIG. 7, the skin surface 50 located between the

rollers

20a and 20b is picked up so as to be wound up with the rotation of the

rollers

20a and 20b.

Next, the effect of the cosmetic device 1 of this example will be described.
According to the cosmetic device 1, the diameter d of the pair of rollers 20 is 15 to 20 mm (first condition), and the shortest distance W between the outer

peripheral surfaces

21a and 21b of the pair of rollers 20 is 7 mm or more and less than 8 mm. (Second condition) are both satisfied. Thus, the pair of rollers 20 can reliably pick up the skin in a narrow portion such as the eyes and the mouth so as not to be excessive and can be pressed effectively. As a result, these parts can be massaged sufficiently. That is, the massage effect of the part is exhibited to the maximum only when both the first condition and the second condition are satisfied.

Further, the diameter d of the pair of rollers 20 is more preferably 18 to 19 mm, and in this example, 18 mm. Thereby, the effect of picking up the skin in a narrow part such as the eyes and mouth is moderately achieved, and the massage effect is more effectively achieved.

The angle β formed by the axes L1 and L2 of the pair of rollers is preferably 70 to 80 °, and more preferably 74 to 76 °. In this example, the angle β formed by the axes L1 and L2 is 74.5 °. Also by this, the effect of picking up skin in a narrow portion such as the eyes and mouth is moderately exerted, and the massage effect is more effectively exhibited.

Further, the handle 10 is formed in a straight line from the first end portion 11 (the base portion of the

branch portions

11a and 11b) to the second end portion 12. Thereby, when using it for a face such as an eye or a mouth, the angle at which the roller 20 abuts against the skin can be easily adjusted, so that the operability is improved. In addition, since the entire beauty device 1 is compactly formed while maintaining the ease of gripping the handle 10, it is suitable for carrying on a trip or the like.

Further, the pair of rollers 20 (20a, 20b) is formed in a spherical shape. Thereby, compared with the case where

roller

20a, 20b is cylindrical, the contact area of

roller

20a, 20b and skin becomes small. Therefore, it becomes easy to apply the pressing force and the picking force by concentrating the

rollers

20a and 20b on a narrow portion such as the eyes and the mouth. Furthermore, since the

rollers

20a and 20b can be smoothly moved even when the skin is pressed, the moving direction of the cosmetic device 1 can be easily changed. Thereby, it becomes easy to massage a narrow part, such as the eyes and mouth, to a pinpoint.

The shape of the

rollers

20a and 20b may be an elliptical sphere or a combination of these shapes in addition to the spherical shape. Moreover, you may provide the unevenness | corrugation and protrusion by various shapes on the surface of

roller

20a, 20b. In this case, the effect of picking up the skin by the

rollers

20a and 20b can be further improved by the irregularities and protrusions. Each of the

rollers

20a and 20b may be composed of a single member, or may be composed of a combination of two or more members.

In addition, the cosmetic device 1 may include other rollers in addition to the pair of rollers 20. The other roller may be the same roller as the pair of rollers 20 or may be a roller having a different mode. For example, the cosmetic device 1 may include two pairs of rollers 20 and a total of four rollers 20.

Further, as shown in FIG. 2, the axes L1 and L2 are on the Y1 side in the direction from the second end 12 opposite to the first end 11 to the first end 11 with respect to the center line L0 of the handle 10. In addition to the inclination, the side projection angle α is set to 90 to 155 °, which is 120 ° in this example. As a result, when used on a face such as the eyes or mouth, the axes L1 and L2 of the pair of

rollers

20a and 20b are appropriately inclined with respect to the skin surface in a state where the handle 10 is gripped. The

rollers

20a and 20b rotate smoothly and the picking effect is effectively exhibited. As a result, the massage effect is improved. Moreover, since the reciprocating operation | movement of the cosmetics device 1 can be performed, without raising an elbow excessively or bending a wrist excessively, it is excellent in operativity. In addition, when the inclination of the axes L1 and L2 of the pair of

rollers

20a and 20b with respect to the skin surface is changed during use, the first end portion 11 of the handle provided with the pair of

rollers

20a and 20b touches the skin surface. Since this is prevented, the risk of burdening the skin can be reduced.

Further, in this example, since the handle 10 is formed in a thin rod shape, for example, the handle 10 is divided into upper and lower or left and right along the center line L0 and each member is accommodated in the handle 10. In such a case, the molding accuracy and strength of the handle 10 may be reduced, or it may be time consuming for each member to seal the inside of the handle 10, and the assembly workability of the cosmetic device 1 may be reduced. However, in this example, as shown in FIG. 4, the handle 10 has each member disposed in a recess 15 formed by hollowing out a part (center portion) of the handle 10 in a concave shape, and the recess 10 The structure which accommodates each member by covering 15 is employ | adopted. As a result, the molding accuracy and strength of the handle 10 can be maintained high as compared with the case where the handle 10 is divided vertically or horizontally along the center line L0 of the handle 10, and the inside of the recess 15 is easily formed by the handle cover 14. Since it can be sealed, the assembling workability of the cosmetic device 1 is improved.
