detailed description

In the said beauty device, it is preferable that the diameter of a pair of rollers is 18-19 mm although the diameter of the said pair of rollers is 15-20 mm as a 1st condition. Thereby, when the said 2nd condition is satisfied, the effect of lifting the skin of narrow parts, such as an eye part and a mouth part, can be moderately exhibited, and a massage effect can be further improved.

When the diameter of the roller is less than 15 mm, the range of the skin that can express the pressing effect and the pulling effect is too narrow. Therefore, in this case, even if the said 2nd condition is satisfied, the massaging effect to narrow parts, such as an eye part and a mouth part, cannot fully be acquired.

On the other hand, when the diameter of the roller is larger than 20 mm, since the size of the roller is relatively large for narrow parts such as eyes and mouth, it is difficult to press and pull these parts. Therefore, in this case, even if the above-mentioned second condition is satisfied, it is difficult to precisely massage these parts.

In the said beauty device, the shortest distance between the outer peripheral surfaces of the said pair of rollers shall be 7 mm or more and 8 mm or less as the said 2nd condition. Therefore, when the above-mentioned first condition is satisfied, the distance between the outer peripheral surfaces of the pair of rollers is neither too wide nor too narrow, but is an optimum range for lifting narrow parts such as eyes and mouths. As a result, these parts can be effectively lifted.

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

On the other hand, when the shortest distance between the outer peripheral surfaces of a pair of rollers is more than 8mm, it is difficult to accurately lift the skin of narrow parts such as eyes and mouth even if the above-mentioned first condition is satisfied. Therefore, it is difficult to precisely massage these parts.

Preferably, the angle formed by the mutual axes of the pair of rollers, that is, the opening angle of the pair of rollers is 70° to 80°. Thereby, when the said 1st condition and the said 2nd condition are satisfied, by making a cosmetics device reciprocate in contact with skin, the lifting effect to the skin of narrow parts, such as an eye part and a mouth part, can be exhibited moderately. As a result, a more effective massage effect can be produced.

When the opening angle of the pair of rollers is 70° or less, the lifting effect on the skin tends to be too strong. Therefore, in this case, even if the above-mentioned first condition and the above-mentioned second condition are met, it is not suitable for use on sensitive parts such as eyes and mouth.

On the other hand, when the opening angle of the pair of rollers is more than 80°, it is difficult to accurately lift the skin of narrow areas such as eyes and mouth even if the first condition and the second condition are met. Therefore, it is difficult to precisely massage these parts.

More preferably, the angle formed by the mutual axes of the pair of rollers, that is, the opening angle of the pair of rollers is 74° to 76°. Therefore, when the above-mentioned first condition and the above-mentioned second condition are satisfied, since the lifting effect on the skin of narrow parts such as eyes and mouth is more moderately exhibited, a more effective massage effect can be exhibited.

Preferably, when viewed from a direction in which the axes of the pair of rollers coincide with each other, the angle formed by the center line of the handle and the axis is 90°-155°. At this time, when using on the face such as the eyes and mouth, in the state of holding the handle, because the axes of the pair of rollers are moderately inclined with respect to the skin surface, the smooth rotation of the pair of rollers can effectively Lifting effect on the skin. As a result, the massage effect is improved. Moreover, since the reciprocating motion of the beauty device can be performed without raising the elbow and bending the wrist excessively, operability is excellent.

When viewed from the direction in which the axes of the pair of rollers coincide with each other, when the angle formed by the center line of the handle and the axis is greater than 155°, when used on the face, because the axes of the pair of rollers are excessive relative to the skin surface The ground is inclined, so it is difficult for a pair of rollers to rotate smoothly. As a result, the friction between the roller and the skin surface increases, increasing the burden on the skin surface. And, in order to alleviate these burdens, it is necessary to twist the wrist holding the handle vigorously to maintain the inclination of the axis of the pair of rollers with respect to the skin surface moderately, so the operability is very poor.

When viewed from the direction in which the axes of the pair of rollers coincide with each other, when the angle formed by the center line of the handle and the axis is less than 90°, when the inclination of the axis of the pair of rollers is changed relative to the skin surface during use, due to The first end of the handle provided with a pair of rollers contacts the surface of the skin, which may increase the burden on the skin, which is not ideal.

Preferably, the handle is formed in a straight line from the first end to the second end. Thus, when the roller is used on the face such as eyes and mouth, it is easy to adjust the contact angle of the roller with respect to the skin surface, so the operability is improved. In addition, since the entire beauty device can be formed compactly while keeping the handle easy to hold, it is suitable for carrying while traveling or the like.

The said cosmetics device may be equipped with other rollers other than said pair of rollers. The other rollers may be the same as the aforementioned pair of rollers, or different types of rollers. For example, the said cosmetics device may be equipped with two sets of said pair of rollers, and may be equipped with four rollers in total.

The diameter S of the thickest part of the handle 10 can be 14-18 mm, in this example 16 mm.

As shown in FIGS. 4 and 5 , a shaft hole 11 c is formed in the branch portion 11 a of the first end portion 11 , and the shaft hole 11 c communicates with a recess 15 formed on the handle main body 13 , which will be described later. The roller shaft 22 is inserted into the shaft hole 11c through a bushing 23 and an O-ring 25 . The roller shaft 22 is made of stainless steel, and nickel plating is applied thereon to have electrical conductivity.

The bushing 23 is made of PA (polyamide) resin and has insulating properties. As shown in FIG. 5 , the bush 23 has a cylindrical bush main body 23 a and a flange-shaped flange portion 23 b formed at an end portion of the bush main body 23 a. The outer shape of the bush main body 23a is slightly smaller than the inner diameter of the shaft hole 11c, and the outer shape of the flange portion 23b is larger than the inner diameter of the shaft hole 11c. While the bush main body 23a is fitted in the shaft hole 11c, the flange portion 23b abuts against the end portion 11e of the branch portion 11a.

Furthermore, a cap 24 is attached to the front end of the branch portion 11a. The cap 24 is made of PA (polyamide) resin and has insulating properties. A through hole 24a is formed in the center of the cap 24, and a peripheral wall portion 24b of the cap 24 is engaged and fixed to the front end of the branch portion 11a in a state where the roller shaft 22 is inserted into the through hole 24a. Thereby, the flange part 23b is sandwiched between the cap 24 and the end part 11e, and the bushing 23 is fixed to the branch part 11a.

As shown in FIG. 5 , an end 22 a of the roller shaft 22 on one end side (the side located in the branch portion 11 a ) is supported by a shaft supporting base 33 b formed on a lens cover 33 described later. On the shaft support stand 33b, the shaft support 36 is arranged. The shaft support 36 is made of stainless steel and is electrically conductive. Furthermore, the end portion 22a of the roller shaft 22 supported by the shaft support stand 33b is in contact with the shaft support 36, so that the roller shaft 22 and the shaft support 36 are electrically energized.

As shown in FIG. 5 , bearings 27 a , 27 b are attached to an end portion 22 b of the roller shaft 22 opposite to the end portion 22 a via a bearing housing 26 and a C-ring 28 . Either of the bearings 27a, 27b is a resin bearing formed of an annular member made of polyoxymethylene. Bearing housing 26 is a substantially cylindrical member made of ABS resin. The roller shaft 22 is inserted into the bearings 27a, 27b, and is held by a bearing housing 26 and a C-ring 28 . On the outer peripheral surface of the bearing housing 26, two roller engaging claws 26a are formed. The roller shaft 22 penetrates the bearing housing 26 in the axial direction, and its end portion 22 a protrudes from the bearing housing 26 . Furthermore, a C-ring 28 is attached to the end portion 22a, and pressurizes the bearings 27a, 27b when preventing the bearings 27a, 27b and the bearing housing 26 from coming off.

Also, as shown in FIG. 5 , the roller 20 a is installed so as to cover the bearing housing 26 . The roller 20a is made of ABS resin, and platinum plating is applied thereto. The shape of the roller 20a is a hollow substantially spherical shape which forms a slightly elongated shape on one side of the branch portion 11a while being open on one side of the branch portion 11a. So-called diamond cutting is applied to the outer peripheral surface 21a of the roller 20a.

Inside the roller 20a, a cup-shaped roller core 29 is provided. The roller core 29 is made of ABS resin, and is integrally formed with the roller 20a. Also, on the inner side of the roller core 29, a seat-engaging groove 29a to be engaged with the roller engaging claw 26a of the bearing housing 26 is formed. Further, the roller 20a is mounted on the bearing housing 26 by engaging the roller engaging claw 26a with the housing-engaging groove 29a. Accordingly, the roller 20 a is attached so as to be rotatable about the axis line L1 of the roller shaft 22 with respect to the branch portion 11 a of the first end portion 11 .

In addition, as shown in FIG. 4 , the roller 20 b has the same configuration as the roller 20 a and is attached so as to be rotatable about the axis L2 of the roller shaft 22 with respect to the branch portion 11 b of the first end portion 11 .

As shown in FIG. 6, the diameter of a pair of rollers 20 (20a, 20b) can be 15-20 mm, 18 mm in this example. Moreover, the shortest distance W between the outer peripheral surfaces 21a, 21b of a pair of roller 20 (20a, 20b) can be 7-8 mm, and it is 7 mm in this example. Furthermore, the angle β formed by the two axes L1, L2 of the pair of rollers 20 (20a, 20b) can be 70-80°, and in this example, it is 74.5°. In addition, the angle β formed by the axes L1 and L2 is an angle formed by the two when viewed in the normal direction IV (see FIG. 2 ) of a plane including the axes L1 and L2.

Furthermore, as shown in FIG. 2 , the axes L1 and L2 are inclined in the direction Y1 from the second end 12 opposite to the first end 11 toward the first end 11 with respect to the center line L of the handle 10 . Moreover, as shown in FIG. 2, when viewed from the direction in which the axes of a pair of rollers coincide with each other, the angle (lateral projection angle) α formed by the centerline L0 and the axis L2 (L1) can be 90 to 155°. In this example it is 120°.

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

A lens cover 33 is provided on the back side of the solar cell panel 31 . At the same time as the two holes 33 a are formed in the lens cover 33 , holes 32 a are also formed in the terminals 32 respectively. Furthermore, the screw 34 insertion holes 33 a and 32 a are connected to the boss 15 a in the recess 15 . Thereby, the lens 30 , the solar battery panel 31 , the terminal 32 and the lens cover 33 are fixed to the handle main body 13 with the solar battery panel 31 interposed between the lens 30 and the lens cover 33 . Further, on one end side of the lens cover 33 (the first end portion 11 side of the handle main body 13 ), the above-mentioned shaft support stand 33 b is formed. Also, the shaft support 36 is mounted in the shaft support stand 33 b through the hole 33 a on the one end side of the lens cover 33 and the screw 34 .

Furthermore, the concave portion 15 is covered by the handle cover 14 . The handle cover 14 has engaging claws 14 a, and the handle cover 14 is fixed to the handle main body 13 by engaging the engaging claws 14 a with engaging grooves (not shown) in the concave portion 15 . Furthermore, O-rings 35 a are interposed between the lens 30 and the handle main body 13 , and O-rings 35 b are interposed between the handle cover 14 and the handle main body 13 .

The solar battery panel 31 is electrically connected to the handle main body 13 to which conductive chrome plating is applied via a terminal 32 . Furthermore, the solar cell panel 31 is electrically connected to a pair of rollers 20 (20a, 20b) coated with conductive platinum plating through a shaft support 36 made of a conductive material, the roller shaft 22, bearings 27a, 27b, and a bearing housing 26. Thereby, when the cosmetics device 1 is used, the roller 20 and the handle 10 are electrically connected through the human body by bringing the outer peripheral surface 21a of the roller 20 into contact with the skin. Then, the solar cell panel 31 receives light through the lens 30 of the window portion 14 to generate electricity, so that 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 is increased, and the massage effect is further improved.

Next, the use state of the cosmetics device 1 is demonstrated.

When using the beauty device 1, as shown in FIG. 7, the user presses the outer peripheral surfaces 21a, 21b of the pair of rollers 20 to the skin surface 50 of narrow parts such as eyes and mouth while holding the handle 10. Simultaneously, the beauty device 1 is moved toward the direction of the 1st end part 11 (direction of the arrow P1 of FIG. 6), and the rollers 20a, 20b rotate in the direction of the arrow P2 centering on each axis|shaft L1, L2. At this time, pressing force is applied to the skin surface using the rollers 20a, 20b. After the beauty device 1 moves toward the P1 direction, when the beauty device 1 moves toward the second end 12 (the direction of the arrow Q1 in FIG. 6 ) to return to the original position, the rollers 20a, 20b rotate in the direction of the arrow Q2. Thereby, as shown in FIG. 7, the skin surface 50 located between the rollers 20a, 20b is pulled up so that it may be pinched as the rollers 20a, 20b rotate.

Next, the operation effect of the cosmetics device 1 of this example is demonstrated.

According to the cosmetic device 1 described above, the diameter d of the pair of rollers 20 is 15 to 20 mm (the first condition), and the shortest distance W between the outer peripheral surfaces 21a and 21b of the pair of rollers 20 is 7 mm to 8 mm (the second condition). ) of these two conditions. As a result, the pair of rollers 20 can reliably lift and effectively press the skin of narrow areas such as the eyes and the mouth without being excessive. As a result, these parts can be fully massaged. That is, only when both the above-mentioned first condition and the second condition are satisfied, the massage effect on the above-mentioned part can be exhibited to the maximum.

Also, more preferably, the diameter d of the pair of rollers 20 is 18 to 19 mm, 18 mm in this example. Thereby, it is possible to moderately exert the lifting effect on the skin of narrow areas such as the eyes and the mouth, and to more effectively exert the massage effect.

Preferably, the angle β formed by the mutual axes L1, L2 of a pair of rollers is 70-80°, more preferably 74-76°. In this example, the angle β formed by the axes L1, L2 is 74.5°. Thereby, the lifting effect to the skin of narrow parts, such as an eye part and a mouth, can be moderately exhibited, and a massage effect can be exhibited more effectively.

In addition, the handle 10 is formed in a straight line from the first end portion 11 (base portions of the branch portions 11 a and 11 b ) to the second end portion 12 . Accordingly, when the roller 20 is used on the face such as eyes and mouth, it is easy to adjust the contact angle of the roller 20 with respect to the skin, thereby improving operability. In addition, while keeping the handle 10 easy to hold, since the whole body of the beauty device 1 is formed compactly, it is suitable for carrying in travel and the like.

Moreover, a pair of roller 20 (20a, 20b) is comprised in spherical shape. Thereby, compared with the case where roller 20a, 20b is cylindrical shape, the contact area of roller 20a, 20b and skin becomes small. Therefore, it is easy to concentrate the rollers 20a and 20b on narrow parts such as the eyes and the mouth, and apply pressing force and pulling force. Furthermore, since the rollers 20a, 20b can move smoothly also in the state which pressed skin, the change of the movement direction of the cosmetics device 1 can be performed easily. This makes it easy to accurately massage narrow areas such as the eyes and mouth.

The shape of the rollers 20a and 20b may be an ellipsoid or a combination of these shapes in addition to the spherical shape. In addition, irregularities and protrusions can be provided in various shapes on the surfaces of the rollers 20a, 20b. In this case, the lifting effect on the skin by the rollers 20a and 20b can be further enhanced by the irregularities and protrusions. In addition, each of the rollers 20a and 20b may be constituted by a single member, or may be constituted by combining two or more members.

Moreover, the cosmetics device 1 may be provided with other rollers other than the pair of rollers 20 . This other roller may be the same roller as the pair of rollers 20, or may be a roller of a different form. For example, the cosmetics device 1 may be equipped with two sets of a pair of rollers 20, and may be equipped with four rollers in total.

In addition, as shown in FIG. 2, the axes L1, L2 are inclined from the second end 12 on the opposite side of the first end 11 toward the direction Y1 side of the first end 11 with respect to the center line L0 of the handle 10. , the side projection angle α is set to 90-155°, in this example it is 120°. Thus, when using on the face such as the eyes and mouth, in the state of holding the handle 10, because the axes L1, L2 of the pair of rollers 20a, 20b are moderately inclined with respect to the skin surface, the pair of rollers 20a , 20b rotate smoothly to achieve an effective lifting effect. As a result, the massage effect is improved. And since the reciprocating motion of the cosmetics device 1 can be performed without raising an elbow too much and bending a wrist too much, it is excellent in operativity. In addition, when changing the inclination of the axes L1, L2 of the pair of rollers 20a, 20b with respect to the skin surface during use, since the first end 11 of the handle provided with the pair of rollers 20a, 20b is prevented from contacting the skin surface, the burden on the skin.

In addition, in this example, the handle 10 is formed in a thin rod shape. For example, when the handle 10 is divided up and down or left and right along the center line L0, and each member is stored inside the handle 10, the forming accuracy and strength of the handle 10 may be reduced. In addition, labor and time required for each member to seal the inside of the handle 10 degrades the assembling workability of the beauty device 1 . However, in this example, as shown in FIG. 4 , the handle 10 is provided with various components in a recess 15 formed by hollowing out a part (central portion) of the handle 10 , and a handle cover 14 is used to cover the handle 10 . The concave portion 15 is used to accommodate the structure of each component. As a result, compared with the case where the handle 10 is divided up and down or left and right along the center line L0 of the handle 10, the high molding accuracy and strength of the handle 10 can be maintained, and the inside of the recess 15 can be easily sealed with the handle cover 14 to improve the appearance. Assembly operability of device 1.
