Summary of the Invention

Problems to be solved by the present invention

For example, in the case of a structure in which the handle is divided into upper and lower parts or left and right parts along the center line and the various components are housed inside the handle, there is a possibility that the molding accuracy and/or strength of the handle will be reduced, or the operation of sealing the interior of the handle with various components will consume more work time, thereby reducing the assembly operability of the beauty device.

The present invention has been developed in view of the above background, and an object of the present invention is to provide a cosmetic device capable of improving assembly workability while maintaining the molding accuracy and/or strength of the handle at a high level.

Means of solving the problem

One embodiment of the present invention is a cosmetic device comprising: a handle body having a rod shape and having a recess formed therein; a pair of branch portions integrally formed at one end of the handle body in a longitudinal direction; axial holes formed in each of the pair of branch portions and communicating with the recess; a pair of roller shafts inserted through the axial holes; a pair of rollers mounted on the pair of roller shafts; and a handle cover covering the recess.

Effects of the Invention

In the above-mentioned cosmetic device, the handle body is rod-shaped, with a pair of branched portions integrally formed at one end in the longitudinal direction. Furthermore, a recessed portion is formed in the handle body, communicating with the axial holes formed in the branched portions and covered by a handle cover. This configuration allows the cosmetic device to maintain higher handle molding accuracy and/or strength than a handle that is split into upper and lower sections or left and right sections. Furthermore, the handle cover allows the interior of the recessed portion to be easily sealed, thereby improving assembly operability of the cosmetic device.

As described above, according to the present invention, it is possible to provide a cosmetic device capable of improving assembly workability while maintaining the molding accuracy and/or strength of the handle at a high level.

DETAILED DESCRIPTION

Preferably, a shaft support stand is provided in the recessed portion, the shaft support stand supporting the roller shaft inserted through the shaft hole. In this case, the roller shaft is supported in the recessed portion to prevent the roller shaft from falling off.

A power supply is housed in the recess, and the power supply is configured to be electrically connected to the roller via the roller shaft, so that a weak electric current flows between the roller and the skin, thereby increasing stimulation to the skin and further improving the massage effect.

In this cosmetic device, the diameter of the pair of rollers is 15-20 mm (the first condition), and the shortest distance between the outer circumferences of the pair of rollers is 7 mm or more and less than 8 mm (the second condition). This ensures that the rollers can reliably lift the skin in narrow areas such as the corners of the eyes and/or mouth without excessive pressure, while also effectively applying pressure. As a result, these areas are fully massaged. In other words, only when both the first and second conditions are met can the massage effect in these areas be maximized.

In the above-mentioned cosmetic device, while the first condition is that the diameter of the pair of rollers be 15 to 20 mm, it is preferable that the diameter of the pair of rollers be 18 to 19 mm. Therefore, when the second condition is met, the skin in narrow areas such as the eye and mouth areas can be appropriately lifted, further enhancing the massage effect.

If the roller diameter is less than 15 mm, the area of the skin where the pressing and lifting effects can be felt is too narrow. Therefore, even if the second condition is met, the massage effect cannot be fully achieved on narrow areas such as the eyes and mouth.

On the other hand, if the roller diameter is larger than 20 mm, it becomes difficult to press and lift narrow areas such as the eyes and mouth because the roller is relatively large. Therefore, in this case, even if the second condition is met, it is difficult to accurately massage these areas.

In the cosmetic device described above, the second condition is that the shortest distance between the outer circumferences of the pair of rollers is at least 7 mm and less than 8 mm. Therefore, when the first condition is met, the distance between the outer circumferences of the pair of rollers is neither too wide nor too narrow, but rather falls within the optimal range for lifting narrow areas such as the eyes and mouth. As a result, these areas can be effectively lifted.

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

On the other hand, if the shortest distance between the outer circumferences of the pair of rollers is 8 mm or more, even if the first condition is met, it is difficult to accurately lift the skin in narrow areas such as the eyes and mouth. Therefore, it is difficult to accurately massage these areas.

Preferably, the angle formed by the axes of the pair of rollers, i.e., the angle of separation between the rollers, is 70-80°. Therefore, when both the first and second conditions are met, the reciprocating motion of the beauty device in contact with the skin can appropriately lift the skin in confined areas such as the eyes and mouth. This results in a more effective massage effect.

If the angle of the pair of rollers is less than 70 degrees, the lifting effect on the skin tends to be too strong. Therefore, in this case, even if the first and second conditions are met, it is not suitable for use on sensitive areas such as the eyes and mouth.

On the other hand, if the opening angle of the pair of rollers exceeds 80 degrees, even if the first and second conditions are met, it is difficult to accurately lift the skin in narrow areas such as the eyes and mouth. Therefore, it is difficult to accurately massage these areas.

More preferably, the angle formed by the axes of the pair of rollers, i.e., the angle of separation between the pair of rollers, is between 74° and 76°. Therefore, when both the first and second conditions are met, the skin in narrow areas such as the eyes and mouth is lifted more appropriately, resulting in a more effective massage effect.

Preferably, when viewed from a direction where the axes of the pair of rollers coincide, the angle formed between the centerline of the handle and the axes is between 90° and 155°. In this case, when used on areas of the face, such as the eyes and mouth, the axes of the rollers are appropriately tilted relative to the skin surface while the handle is gripped. This allows the rollers to rotate smoothly, effectively lifting the skin. This results in an enhanced massage effect. Furthermore, since the reciprocating motion of the beauty device can be performed without raising the elbow or excessively bending the wrist, operability is excellent.

When the angle formed by the centerline of the handle and the axes of the pair of rollers, as viewed from a direction where their axes coincide, exceeds 155°, the axes of the rollers become excessively tilted relative to the skin surface during use on the face, making smooth rotation of the rollers difficult. This increases friction between the rollers and the skin surface, placing increased strain on the skin. Furthermore, to reduce this strain, the wrist holding the handle must be twisted vigorously to maintain a moderate tilt between the axes of the rollers relative to the skin surface, resulting in poor operability.

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 axes of the pair of rollers relative to the skin surface is changed during use, the first ends of the handles on which the pair of rollers are provided contact the skin surface, which may increase the burden on the skin, which is not ideal.

The handle is preferably formed into a straight line from the first end to the second end. This improves operability by making it easier to adjust the angle of contact between the roller and the skin surface when used on areas of the face, such as the eyes and mouth. Furthermore, the handle remains easy to grip while maintaining a compact design, making the beauty device suitable for travel and other occasions.

The cosmetic device may include additional rollers in addition to the pair of rollers. The additional rollers may be the same as the pair of rollers or may be of a different type. For example, the cosmetic device may include two sets of the pair of rollers, for a total of four rollers.

[Example]

(Example 1)

The cosmetics device according to the embodiment of this example will be described using FIG. 1 to FIG. 7 .

As shown in FIG. 1 , the cosmetics device 1 of this embodiment includes a handle body 13 , a pair of roller shafts 22 , a pair of rollers 20 , and a handle cover 14 .

The handle body 13 is rod-shaped and has a recess 15 formed therein.

A pair of branch portions 11 a and 11 b are integrally formed at the first end portion 11 , which is one end of the handle body 13 in the longitudinal direction Y.

As shown in FIG. 4 and FIG. 5 , an axial hole 11 c communicating with the recess 15 is formed in the pair of branch portions 11 a and 11 b.

A pair of roller shafts 22 are inserted through the shaft holes 11 c.

The pair of rollers 20 are mounted on a pair of roller shafts 22 .

The handle cover 14 covers the recess 15 .

In this example, as shown in FIG6 , a pair of rollers 20 are supported on the first end portion 11 of the handle 10 so as to be rotatable about respective axes L1 and L2, separated from each other. Furthermore, the axes L1 and L2 are arranged to be inclined relative to the center line L0 of the handle 10 in a direction (the Y1 direction shown in FIG1 ) from the second end portion 12 located on the opposite side of the first end portion 11 toward the first end portion 11.

Furthermore, the diameter d of the pair of rollers 20 is 15 to 20 mm, and the shortest distance W between the outer peripheral surfaces 21 a and 21 b of the pair of rollers 20 is 7 mm or more and less than 8 mm.

In this example, only a pair of rollers 20 are provided as the plurality of rollers, and the diameter d thereof is 18 mm and the shortest distance W thereof is 7 mm.

Hereinafter, the cosmetics device 1 of this example will be described in detail.

As shown in Figures 1 and 3, the handle 10 is formed in a rod shape. The handle 10 includes a handle body 13 and a handle cover 14. The handle body 13 is made of ABS resin and is chrome-plated. Forked branches 11a and 11b are formed on the first end 11 on one end side of the length direction of the handle body 13. The diameter of the handle body 13 decreases as it moves toward the second end 12 on the other end side. Moreover, the handle body 13 is formed in a straight line from the first end 11 (the root of the branches 11a and 11b) to the second end 12. The diameter S of the thickest part of the handle 10 can be 14 to 18 mm, and in this example, it is 16 mm.

As shown in Figures 4 and 5 , a shaft hole 11c is formed in the branch portion 11a of the first end portion 11. This shaft hole 11c communicates with a recess 15 (described later) formed in the handle body 13. A roller shaft 22 is inserted into the shaft hole 11c via a bushing 23 and an O-ring 25. The roller shaft 22 is made of stainless steel and nickel-plated for electrical conductivity.

The bushing 23 is made of PA (polyamide) resin and has insulating properties. As shown in Figure 5, the bushing 23 has a cylindrical bushing body 23a and a flange-like lip portion 23b formed at the end of the bushing body 23a. The outer shape of the bushing body 23a is slightly smaller than the inner diameter of the shaft hole 11c, while the outer shape of the lip portion 23b is larger than the inner diameter of the shaft hole 11c. When the bushing body 23a is inserted into the shaft hole 11c, the lip portion 23b abuts against the end 11e of the branch portion 11a.

Furthermore, a cap 24 is attached to the tip of the branch portion 11a. Made of PA (polyamide) resin, the cap 24 has insulating properties. A through-hole 24a is formed in the center of the cap 24. With the roller shaft 22 inserted into the through-hole 24a, the peripheral wall 24b of the cap 24 engages and secures the tip of the branch portion 11a. This secures the flange 23b between the cap 24 and the end portion 11e, securing the bushing 23 to the branch portion 11a.

As shown in Figure 5, the end 22a of the roller shaft 22 at one end (the side located within the branch portion 11a) is supported on a shaft support 33b formed on the lens cover 33, described later. A bearing seat 36 is mounted on the shaft support 33b. The bearing seat 36 is made of conductive stainless steel. Furthermore, the end 22a of the roller shaft 22 supported on the shaft support 33b contacts the bearing seat 36, ensuring electrical continuity between the roller shaft 22 and the bearing seat 36.

As shown in Figure 5, bearings 27a and 27b are mounted on the end 22b opposite the end 22a of the roller shaft 22 via a bearing holder 26 and a C-ring 28. Each bearing 27a and 27b is a resin bearing formed of a polyoxymethylene ring. The bearing holder 26 is a roughly cylindrical member made of ABS resin. The roller shaft 22 is inserted into the bearings 27a and 27b and retained by the bearing holder 26 and the C-ring 28. Two roller engagement claws 26a are formed on the outer circumference of the bearing holder 26. The roller shaft 22 axially penetrates the bearing holder 26, with its end 22a protruding from the bearing holder 26. Furthermore, the C-ring 28 is mounted on the end 22a to apply preload to the bearings 27a and 27b, preventing them from falling out of the bearing holder 26.

As shown in Figure 5, roller 20a is mounted so as to cover bearing housing 26. Roller 20a is made of ABS resin and is platinum-plated. Roller 20a has a hollow, roughly spherical shape, with an open side at branch portion 11a and a slightly elongated shape formed on one side of branch portion 11a. The outer circumferential surface 21a of roller 20a is diamond-cut.

A cup-shaped roller core 29 is provided inside the roller 20a. The roller core 29 is made of ABS resin and is integrally molded with the roller 20a. Furthermore, a seat engagement groove 29a is formed inside the roller core 29, which engages with the roller engagement claw 26a of the bearing seat 26. The roller 20a is mounted on the bearing seat 26 by engaging the roller engagement claw 26a with the seat engagement groove 29a. Thus, the roller 20a is mounted so as to be rotatable about the axis L1 of the roller shaft 22 relative to the branch portion 11a of the first end portion 11.

4 , the roller 20 b has the same structure as the roller 20 a and is attached to the branch portion 11 b of the first end portion 11 so as to be rotatable about the axis L2 of the roller shaft 22 .

As shown in Figure 6 , the diameter of the pair of rollers 20 ( 20a , 20b ) can be 15 to 20 mm, and in this example, it is 18 mm. Furthermore, the shortest distance W between the outer circumferential surfaces 21a , 21b of the pair of rollers 20 ( 20a , 20b ) can be at least 7 mm but less than 8 mm, and in this example, it is 7 mm. Furthermore, the angle β formed by the axes L1 and L2 of the pair of rollers 20 ( 20a , 20b ) can be 70 to 80°, and in this example, it is 74.5°. The angle β formed by the axes L1 and L2 is the angle formed when viewed in the normal direction IV (see FIG. 2 ) of the plane containing the axes L1 and L2.

Furthermore, as shown in FIG2 , the axes L1 and L2 are inclined relative to the center line L of the handle 10 in a direction Y1 from the second end 12 located on the opposite side of the first end 11 toward the first end 11. Furthermore, as shown in FIG2 , when viewed in a direction in which the axes of the pair of rollers coincide with each other, the angle (lateral projection angle) α formed by the center line L0 and the axis L2 (L1) can be 90 to 155°, and in this example is 120°.

As shown in Figure 1, a window 13a is formed in the center of the front side of the handle 10, toward the first end 11. Meanwhile, as shown in Figure 4, a recess 15 is formed in the center of the back side of the handle 10, communicating with the window 13a. Furthermore, a lens 30 is inserted into the back side of the window 13a. Furthermore, a solar panel 31 is positioned on the back side of the lens 30. Two terminals 32 are connected to the solar panel 31.

A lens cover 33 is provided on the back side of the solar cell panel 31. Two holes 33a are formed on the lens cover 33, and holes 32a are also formed on the terminals 32. Furthermore, screws 34 are inserted into the holes 33a and 32a to connect with the boss 15a in the recess 15. Thus, with the solar cell panel 31 interposed between the lens 30 and the lens cover 33, the lens 30, the solar cell panel 31, the terminal 32 and the lens cover 33 are fixed to the handle body 13. Furthermore, the above-mentioned shaft support 33b is formed on one end side of the lens cover 33 (on the side of the first end portion 11 of the handle body 13). Furthermore, the bearing seat 36 is mounted on the shaft support 33b through the hole 33a and the screw 34 on one end side of the lens cover 33.

The recess 15 is covered by the handle cover 14. The handle cover 14 includes an engagement claw 14a, and the engagement claw 14a engages with an engagement groove (not shown) in the recess 15 to fix the handle cover 14 to the handle body 13. Furthermore, an O-ring 35a is interposed between the lens 30 and the handle body 13, and an O-ring 35b is interposed between the handle cover 14 and the handle body 13.

The solar panel 31 is electrically connected to the handle body 13, which is coated with conductive chrome, via the terminal 32. Furthermore, the solar panel 31 is electrically connected to a pair of rollers 20 (20a, 20b), which are coated with conductive platinum, via a bearing seat 36, a roller shaft 22, and a bearing seat 26, all formed of a conductive material. Thus, when the beauty device 1 is used, the outer peripheral surface 21a of the roller 20 is brought into contact with the skin, so that the roller 20 and the handle 10 are electrically connected via the human body. Furthermore, the solar panel 31 generates electricity by receiving light through the lens 30 of the window portion 13a, causing a weak current to flow between the outer peripheral surface 21a of the roller 20 and the skin. As a result, stimulation of the skin is increased, further enhancing the massage effect.

Next, a usage state of the cosmetics device 1 will be described.

When using the cosmetic device 1, as shown in FIG7 , the user grips the handle 10 and, while pressing the outer circumferential surfaces 21a and 21b of the pair of rollers 20 against the skin surface 50 in narrow areas such as the eye and mouth areas, moves the cosmetic device 1 toward the first end 11 (in the direction of arrow P1 in FIG6 ), and the rollers 20a and 20b rotate in the direction of arrow P2 about their respective axes L1 and L2. At this time, the rollers 20a and 20b apply a pressing force to the skin surface. After the cosmetic device 1 moves in the direction P1, as the cosmetic device 1 returns to its original position by moving toward the second end 12 (in the direction of arrow Q1 in FIG6 ), the rollers 20a and 20b rotate in the direction of arrow Q2. As a result, as shown in FIG7 , the skin surface 50 between the rollers 20a and 20b is lifted and rolled up as the rollers 20a and 20b rotate.

Next, the effects of the cosmetics device 1 of this example will be described.

According to the cosmetic device 1 of this embodiment, the handle 10 has a rod-shaped handle body 13 integrally formed with a pair of branch portions 11a and 11b at one end in the longitudinal direction Y. Furthermore, a recess 15 is formed in the handle body 13. This recess 15 communicates with the axial hole 11c formed in the branch portions 11a and 11b and is covered by a handle cover 14. This structure of the cosmetic device 1 maintains a higher degree of molding accuracy and/or strength than would be achieved by dividing the handle 10 into vertical or horizontal sections. Furthermore, the handle cover 14 allows the interior of the recess 15 to be easily sealed, thereby improving assembly operability of the cosmetic device 1.

In the cosmetic device 1 of this embodiment, a shaft support 33b is provided in the recess 15 to support the roller shaft 22 inserted through the shaft hole 11c. Thus, the roller shaft 22 is supported in the recess 15 to prevent it from falling off.

Furthermore, in the cosmetic device 1 of this embodiment, a solar panel 31 serving as a power source is housed within the recess 15. This solar panel 31 is electrically connected to the rollers 20a and 20b via the roller shaft 22, allowing a weak current to flow between the rollers 20a and 20b and the skin. This increases skin stimulation and further enhances the massage effect.

Furthermore, the cosmetic device 1 satisfies both the first condition that the diameter d of the pair of rollers 20 is 15 to 20 mm, and the second condition that the shortest distance W between the outer circumferences 21a and 21b of the pair of rollers 20 is 7 mm or more and less than 8 mm. This ensures that the rollers 20 can reliably lift the skin in narrow areas such as the eye and mouth areas without excessive pressure, while also providing effective compression. Consequently, these areas can be fully massaged. In other words, only when both the first and second conditions are met can the massage effect on these areas be maximized.

Furthermore, the diameter d of the pair of rollers 20 is more preferably 18 to 19 mm, and in this example is 18 mm. This can appropriately provide a lifting effect on the skin of narrow areas such as the eyes and mouth, and more effectively provide a massage effect.

The angle β formed by the axes L1 and L2 of the pair of rollers is preferably 70-80°, more preferably 74-76°. In this example, the angle β formed by the axes L1 and L2 is 74.5°. This ensures a moderate lifting effect on the skin in narrow areas such as the eyes and mouth, further enhancing the massage effect.

Furthermore, the handle 10 is formed in a straight line from the first end 11 (the base of the branches 11a and 11b) to the second end 12. This improves operability by making it easier to adjust the angle of contact between the roller 20 and the skin when used on areas of the face, such as the eyes and mouth. Furthermore, while maintaining an easy grip on the handle 10, the compact design of the cosmetics device 1 makes it suitable for travel and other occasions.

Furthermore, the pair of rollers 20 (20a, 20b) are spherical. This reduces the contact area between the rollers 20a, 20b and the skin compared to cylindrical rollers. This makes it easier to focus the rollers 20a, 20b on narrow areas such as the eyes and mouth, applying both pressing and lifting forces. Furthermore, because the rollers 20a, 20b can be moved smoothly even while pressing against the skin, the direction of movement of the beauty device 1 can be easily changed. This makes it easier to precisely massage narrow areas such as the eyes and mouth.

The rollers 20a and 20b can be spherical, ellipsoidal, or a combination of these shapes. Furthermore, the surfaces of the rollers 20a and 20b can be provided with various shapes of concavities and convexities. These concavities and convexities can further enhance the skin-lifting effect of the rollers 20a and 20b. Furthermore, the rollers 20a and 20b can each be composed of a single member or a combination of two or more members.

Furthermore, the cosmetic device 1 may include other rollers in addition to the pair of rollers 20. The other rollers may be the same as the pair of rollers 20 or may be rollers of a different form. For example, the cosmetic device 1 may include two pairs of rollers 20, for a total of four rollers.

Furthermore, as shown in Figure 2, the axes L1 and L2 are inclined relative to the centerline L0 of the handle 10 in the direction Y1 from the second end 12, located opposite the first end 11, toward the first end 11. The lateral projection angle α is set to 90 to 155°, 120° in this example. This allows the pair of rollers 20a and 20b to rotate smoothly when used on areas of the face, such as the eyes and mouth, while the handle 10 is being gripped. This effectively lifts the skin, as the axes L1 and L2 of the pair of rollers 20a and 20b are appropriately tilted relative to the skin surface. This results in an enhanced massage effect. Furthermore, since the cosmetic device 1 can be reciprocated without excessive elbow lift or wrist bending, operability is excellent. Furthermore, changing the tilt of the axes L1 and L2 of the pair of rollers 20a and 20b relative to the skin surface during use prevents the first end 11 of the handle, where the pair of rollers 20a and 20b are located, from contacting the skin surface, thereby reducing the burden on the skin.

Furthermore, in this example, the handle 10 is formed into a thin rod shape. For example, if the handle 10 is divided vertically or horizontally along the centerline L0 and the various components are housed within the handle 10, the molding accuracy and strength of the handle 10 may be reduced. Furthermore, the labor and time required to seal the interior of the handle 10 with each component would reduce the ease of assembly of the cosmetic device 1. However, in this example, as shown in FIG4 , the handle 10 has a structure in which the various components are housed within a recess 15 formed by hollowing out a portion (the center portion) of the handle 10. This recess 15 is then covered with a handle cover 14 to house the components. This structure maintains the high molding accuracy and strength of the handle 10 compared to a structure in which the handle 10 is divided vertically or horizontally along the centerline L0. Furthermore, the interior of the recess 15 can be easily sealed with the handle cover 14, thereby improving the ease of assembly of the cosmetic device 1.
