Description

Beauty device

The application is a divisional application of invention patent application 201210115400.8 filed on 4, 10/2012.

Technical Field

The present invention relates to a beauty device which massages the skin of a face, an arm, or the like by a rotary body for massage provided on a handle, thereby promoting blood flow and achieving a skin beautifying effect.

Background

Various types of beauty devices have been proposed, and for example, patent document 1 discloses a skin roller. That is, the skin roller includes a handle and a pair of rollers provided at one end of the handle, and the rotation axis of the roller is set to be at an acute angle to the center line in the longitudinal direction of the handle. Further, the angle formed by the rotation axes of the pair of rollers is set to be an obtuse angle. When the skin makeup roller is pulled in the opposite direction while being pressed, the skin is sandwiched between the rollers, and the pores are collapsed. Therefore, the skin makeup roller can effectively remove dirt in pores.

Patent document 1: japanese laid-open patent publication No. 2009-142509

However, in the skin roller of the conventional structure described in patent document 1, since the center line of the handle and the rotation axes of the two rollers are on the same plane (see fig. 2 of patent document 1), when the handle of the skin roller is held by a hand and the two rollers are pressed against the skin, the elbow must be raised, the wrist must be bent so that the fingers face the skin side, and the handle must be made perpendicular to the skin. Therefore, there is a problem that the operability of the skin makeup roller is poor and the state of action of the roller on the skin greatly changes depending on the wrist angle.

Further, since each roller of the skin makeup roller is formed in an elliptical cylindrical shape, when the roller is pressed in one direction, the area of the pressed skin is large, and pores are not sufficiently opened. Further, when the rollers are pulled in the opposite direction, the skin located between the two rollers is stretched in a region corresponding to the length of the rollers, and therefore, it is difficult to reliably nip the two rollers. As a result, the pores are insufficiently expanded and contracted, and dirt in the pores cannot be removed completely. In addition, since the roller is formed in an elliptic cylindrical shape, it makes linear contact with the skin, and the resistance to the muscle is large, and the movement is not smooth, and the movement direction is easily restricted. Therefore, there is a problem that the operability of the skin makeup roller is poor.

Disclosure of Invention

The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a beauty device which can exert an excellent massage effect on the skin, can continuously exert the pressing effect and the pulling effect on the skin at present, and has good operability.

In order to achieve the above object, the present invention provides a beauty device including a handle and a pair of rotating bodies supported at a distal end portion of the handle so as to rotate around respective axes at an interval therebetween, the axes of the rotating bodies being inclined forward with respect to a center line of the handle so that the axes of the rotating bodies maintain a predetermined angle with respect to a muscle surface during reciprocating motion, an opening angle of a pair of rotating body support shafts being set to 40 to 120 degrees, an interval between outer peripheral surfaces of the pair of rotating bodies being set to 8 to 25mm, and skin being pulled up by the outer peripheral surfaces of the rotating bodies coming into contact with skin and moving from the distal end of the handle toward a proximal end.

Effects of the invention

The beauty device of the present invention can exhibit the following effects.

In the cosmetic device of the present invention, the pair of rotating bodies are supported at the distal end portion of the handle so as to rotate around respective axes at a distance from each other, and the axes of the rotating bodies are inclined forward with respect to the center line of the handle. That is, the axis of the rotator is kept at a predetermined angle with respect to the muscle surface in the reciprocating motion. Therefore, when the pair of rotating bodies are pressed against the skin by holding the handle, the wrist does not need to be bent, and the skin can be pressed when the cosmetic device is moved forward while the wrist is kept straight, and the skin can be pulled up when the cosmetic device is moved backward.

Further, since the portion in contact with the skin is not a cylindrical roller but a circular rotating body, the rotating body is in partial contact with the skin. Therefore, the rotating body can intensively apply the pressing force and the pulling force to a part of the skin, and the rotating body can smoothly move on the skin, and the degree of freedom in the moving direction is high.

Thus, according to the cosmetic device of the present invention, it is possible to continuously exert the pressing effect and the pulling effect on the skin while exerting the excellent massage effect on the skin, and to improve the operability.

Detailed Description

Next, an embodiment of a beauty device embodying the present invention will be described with reference to fig. 1 to 7.

As shown in fig. 1, a two-thigh portion 11a having a Y-shaped plan shape is provided at the tip of a handle 11 constituting the beauty device 10 of the present embodiment. As shown in fig. 6, the handle 11 is composed of an electrically insulating base 12 and a handle cover 13 covering the outer periphery of the base 12, the base 12 is formed of synthetic resin such as ABS resin, and the handle cover 13 is composed of an upper handle cover 13a and a lower handle cover 13 b. The upper handle cover 13a and the lower handle cover 13b are each formed of synthetic resin, and conductive plating is applied to the outer surfaces of the covers 13a and 13b, and the handle cover 13 is connected to the base 12 by a plurality of screws 14.

As shown in fig. 7, a pair of support cylinders 16 are integrally formed on the base 12 at the two-leg portion 11a of the handle 11, and a metallic rotor support shaft 15 is supported on the support cylinders 16. A cap 18 is fitted to the outer periphery of the distal end of the bifurcated portion 11a of the handle 11, and the cap 18 is formed of synthetic resin and is formed in a cylindrical shape. The cap 18 is fitted to seal the distal end of the bifurcated portion 11a, thereby preventing the rotation body support shaft 15 from rattling and ensuring electrical insulation between the conductive portions between the outer surface of the bifurcated portion 11a and the outer surface of the rotation body 17, which will be described later.

A bearing member 19 is fitted to the projecting end portion of the rotor support shaft 15, the bearing member 19 is cylindrical and made of synthetic resin, and the inner and outer peripheries thereof are plated with metal, and the bearing member 19 is fixed to the rotor support shaft 15 so as to be prevented from coming off by a stopper ring 25. A pair of elastically deformable claws 19a is provided on the outer periphery of the bearing member 19 in a protruding manner. A rotary body 17 is rotatably fitted and supported in a bearing member 19 of the rotary body support shaft 15, and the rotary body 17 is spherical. The rotating body 17 is composed of a core member 26, a cover member 27, and a sheath member 28. The core member 26 is formed of synthetic resin. The cover member 27 is made of synthetic resin and fitted to the inner periphery of the front end of the core member 26. The outer skin member 28 is formed of a synthetic resin and is formed to cover the outer periphery of the core member 26.

The outer surface of the outer skin member 28 is plated with a conductive metal as a conductive portion, and is electrically connected to the metal plating of the bearing member 19. A step portion 26a that can engage with the claw 19a of the bearing member 19 is formed on the inner periphery of the core member 26. In a state where the rotary body 17 is fitted into the bearing member 19, the claws 19a engage with the stepped portions 26a, and the rotary body 17 is held in the bearing member 19 so as to be prevented from coming off. As shown in fig. 3 and 4, a plurality of surfaces 17a for applying stimulation to the tissue of the skin 20 are formed on the outer peripheral surface of each rotating body 17.

A permanent magnet 22 is disposed inside each of the rotating bodies 17, and the permanent magnet 22 generates power in accordance with the rotation of the rotating body 17. The permanent magnet 22 is formed in a cylindrical shape from magnetic steel, and is configured to be rotatable integrally with the rotor 17. As the rotor 17 rotates, the permanent magnets 22 rotate relative to the rotor support shaft 15 at a slight interval, and thus minute electric power is generated on the surface of the rotor support shaft 15 due to minute irregularities, minute deviations in roundness, and the like, and is transmitted to the conductive portion on the outer peripheral surface of the rotor 17.

As shown in fig. 2 and 6, a transparent plate 23 is provided on the distal end side of the handle 11, that is, on the crotch side of the two-thigh portion 11a, and a solar cell panel 24 is provided inside thereof, and an output terminal, not shown, of the solar cell panel 24 is connected to the handle 11 and the conductive portion of the rotating body 17. Therefore, the electric power generated by the solar cell panel 24 is supplied to the handle 11 and the conductive portion of the rotating body 17. Therefore, when the beauty treatment device 10 is used, the electricity of the solar cell panel 24 between the handle 11 and the rotating body 17 flows through the human body, and a beauty treatment effect can be obtained.

The beauty device 10 of the present embodiment can be applied not only to the face as described above but also to body parts such as the neck, arms, and legs.

As shown in fig. 3, the axis of the rotating body support shaft 15 is formed to be inclined forward with respect to the center line x of the handle 11 so that the axis of the rotating body support shaft 15 can maintain a predetermined angle with respect to the skin 20 surface during the reciprocating operation of the cosmetic device 10. Specifically, the side projection angle α formed by the axis y of the rotator 17, that is, the axis y of the rotator support shaft 15, with respect to the center line x of the handle 11 (a line parallel to a line bisecting the angle between the outer peripheral lines z of the thickest portions of the handle 11) is preferably 90 to 110 degrees so that the rotator 17 is tilted forward with respect to the center line x of the handle 11 to improve the operability. The side projection angle α is further preferably 93 to 100 degrees, and most preferably 95 to 99 degrees. When the side projection angle α is smaller than 90 degrees or larger than 110 degrees, the forward tilt angle of the rotating body support shaft 15 is too small or too large, and when the rotating body 17 is pressed against the skin 20, the elbow must be raised or lowered, or the wrist must be bent largely, so that the operability of the cosmetic device 10 is deteriorated, and it is difficult to adjust the angle of the rotating body support shaft 15 with respect to the skin 20 surface.

As shown in fig. 5, in order to achieve the pressing effect and the pulling-up effect on the skin 20 well by the reciprocating operation of the rotating bodies 17, the opening angle of the pair of rotating bodies 17, that is, the opening angle β of the pair of rotating body support shafts 15 is preferably set to 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees. When the opening angle β is less than 50 degrees, the pulling effect on the skin 20 is too strong, which is not preferable. Further, when the opening angle β is larger than 110 degrees, it is not preferable because it is difficult to pull up the skin 20 between the rotators 17.

In order to use the beauty device 10 mainly on the face or arm, the diameter L of each rotating body 17 is preferably 15 to 60mm, more preferably 32 to 55mm, and particularly preferably 38 to 45 mm. When the diameter L of the rotating body 17 is less than 15mm, the range of the skin 20 that can exhibit the pressing effect and the pulling-up effect is narrow, which is not preferable. In addition, when the diameter L of the rotating body 17 is larger than 60mm, the rotating body 17 is large in size relative to the face or arm, and therefore, it is difficult to press or pull up a narrow portion, which is inconvenient to use.

In order to pull up the skin 20 appropriately, the distance D between the outer peripheral surfaces of the two rotators 17 is preferably 8 to 25mm, more preferably 9 to 15mm, and particularly preferably 10 to 13 mm. When the distance D between the outer peripheral surfaces of the pair of rotating bodies 17 is less than 8mm, the effect of pulling on the skin 20 located between the rotating bodies 17 is too large, which is not preferable. Further, if the distance D between the outer peripheral surfaces of the two rotating bodies 17 is larger than 25mm, it is not preferable because it is difficult to pull up the skin 20 located between the rotating bodies 17.

Next, the operation of the beauty device 10 of the embodiment configured as described above will be described.

When the user uses the beauty device 10, as shown in fig. 3, in a state where the user holds the handle 11, the outer peripheral surface of the rotating body 17 is pressed against and brought into contact with the skin 20 of the face, the arm, or the like shown by the two-dot chain line in fig. 3, and when the user moves forward from the base end of the handle 11 toward the distal end (the left direction in fig. 3), the rotating body 17 rotates about the rotating body support shaft 15. At this time, as shown by the two-dot chain line in fig. 3, the rotating body 17 applies a pressing force to the skin 20. When the rotating body 17 is moved backward to return to the original position after the rotating body 17 is moved forward, the skin 20 positioned between the two rotating bodies 17 is pulled up along with the rotation of the rotating body 17 as shown by the two-dot chain line in fig. 4.

That is, as shown in fig. 5, when the two rotating bodies 17 move in the normal direction of the arrow P1, each rotating body 17 rotates in the direction of the arrow P2. Therefore, the skin 20 is pressed so as to be pressed open. When the two rotating bodies 17 move in the reverse direction of the arrow Q1, each rotating body 17 rotates in the direction of the arrow Q2. Therefore, the skin 20 positioned between the two rotating bodies 17 is rolled up and pulled up.

Further, when the two rotating bodies 17 are moved in the forward direction, the skin 20 is pressed by the two rotating bodies 17, and the skin 20 between the two rotating bodies 17 is pulled up as a reaction to the pressing force.

In this case, the rotation body support shaft 15 is tilted forward with respect to the center line x of the handle 11, and specifically, the side projection angle α of the rotation body support shaft 15 with respect to the center line x of the handle 11 is set to 90 to 110 degrees, so that the reciprocating operation of the beauty device 10 can be performed without raising the elbow or bending the wrist. Further, the operation can be continued while keeping the axis y of the rotor support shaft 15 at a right angle to the skin 20 surface. Therefore, the rotating body 17 can be effectively pressed against the skin 20, and a massage effect can be exhibited satisfactorily.

Further, since the portion in contact with the skin 20 is constituted by the circular rotating body 17, not the conventional cylindrical roller, the area in contact with the skin 20 of the rotating body 17 is narrower than that of the roller. Therefore, the rotating body 17 can concentrate the pressing force and the pulling force acting locally on the skin 20, and the rotating body 17 can smoothly move on the skin 20, and the moving direction can be easily changed.

Therefore, the skin 20 such as the face and the arm is massaged by the pressing force generated by the rotation of the rotating body 17, and the blood flow in the area is promoted and the circulation of the lymph is promoted. Further, since the opening angle β of the pair of rotating bodies 17 is set to 50 to 110 degrees and the distance D between the outer peripheral surfaces of the two rotating bodies 17 is set to 8 to 25mm, it is possible to apply an appropriate pressing force to a desired skin 20 portion and to comfortably massage the skin 20 without making the pulling of the skin 20 excessively strong or weak. Further, since the diameter L of the rotating body 17 is set to 15 to 60mm, the operation of the beauty treatment apparatus 10 can be quickly advanced appropriately according to the face or the arm. Therefore, for example, the slack portion of the skin 20 can be also subjected to pulling massage as expected.

In addition, when the skin 20 is stretched by the pressing force of the rotating bodies 17, the pores are opened, and when the skin 20 is pulled between the rotating bodies 17, the pores are contracted, and dirt in the pores can be removed. In addition, since the skin 20 of the user is in contact with the outer peripheral surface of the rotator 17 and the hand of the user is in contact with the conductive portion on the surface of the handle 11, a weak current flows from the rotator 17 through the skin 20 and the hand of the user by the electric power generated by the solar cell panel 24 as shown in fig. 3, and the skin 20 is stimulated, whereby the blood flow and the circulation of the lymph fluid are promoted. Thus, these massaging action, pressing/pulling action, lifting action, pore stain removing action, electrical stimulation action, and the like are combined and applied to the skin 20 in an assisting manner, and an ideal skin beautifying effect is exerted.

Therefore, according to this embodiment, the following effects can be obtained.

(1) In the cosmetic device 10 of the present embodiment, the pair of rotary bodies 17 are rotatably supported about the respective axes y at intervals from each other, and the side projection angle α of the axis y of the rotary body 17 with respect to the center line x of the handle 11 is set to 90 to 110 degrees so that the rotary body support shaft 15 is tilted forward with respect to the center line x of the handle 11. That is, since the axis y of the rotary bodies 17 is inclined forward with respect to the center line x of the handle 11, when the handle 11 is held and the pair of rotary bodies 17 is pressed against the skin 20, it is not necessary to raise the elbow or bend the wrist significantly. Therefore, the cosmetic device 10 can be easily reciprocated, and the skin 20 can be pressed and pulled up.

Further, since the portion in contact with the skin 20 is constituted by the circular rotating body 17, the pressing force and the assembling force can be intensively applied to the desired portion of the skin 20, and the rotating body 17 can be smoothly moved with respect to the skin 20, and the degree of freedom in the moving direction is high.

Thus, according to the cosmetic device 10 of the present embodiment, it is possible to exhibit a beneficial massage effect on the skin 20, and to significantly continuously exhibit a pressing effect and a pulling-up effect on the skin 20, and to achieve good operability.

(2) The side projection angle α of the axis y of the rotating body 17 is preferably 93 to 100 degrees, and more preferably 95 to 99 degrees, so that the operability of the cosmetic device 10 and the cosmetic effect such as a massage effect can be further improved.

(3) The opening angle β of the pair of rotating bodies 17 is preferably 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees, so that the pressing effect and the pulling effect of the beauty device 10 can be further improved.

(4) The diameter L of the rotating body 17 is preferably 15 to 60mm, more preferably 32 to 55mm, and particularly preferably 38 to 45mm, so that the cosmetic device 10 can be suitably applied to the face and the arm, and the massage effect and the operability can be improved.

(5) The distance D between the outer peripheral surfaces of the two rotating bodies 17 is preferably 8 to 25mm, more preferably 9 to 15mm, and particularly preferably 10 to 13mm, so that the skin 20 can be pulled up comfortably with appropriate strength while an appropriate pressing effect can be obtained on a desired part of the skin 20.

(6) In the beauty device 10, the power source is constituted by a solar cell panel 24 provided on the handle 11. Therefore, a weak current flows from the rotator 17 to the skin 20 by the power generated from the solar cell panel 24 without providing a power source such as a dry battery.

(7) In the beauty device 10 of the present embodiment, a permanent magnet 22 for generating power with the rotation of the rotating body 17 is disposed. Therefore, a minute electric power can be obtained by the rotation of the rotating body 17, and a minute electric current can be applied from the rotating body 17 to the skin 20 by the minute electric power.

The distance D between the outer peripheral surfaces of the rotating bodies 17 was evaluated for the beauty device 10 mainly applied to the face.

That is, the evaluation of the distance D between the outer peripheral surfaces of the rotating bodies 17 was performed by changing the distance D between the outer peripheral surfaces of the rotating bodies 17 from 6mm to 15mm with the side projection angle α of the cosmetic device 10 set to 97 degrees, the opening angle β of the rotating bodies 17 set to 70 degrees, the diameter L of the rotating bodies 17 set to 40 mm. The evaluation method was performed in the same manner as in example 1 described above. The results obtained are shown in Table 6.

As shown in table 6, the results of example 42 in which the distance D between the outer peripheral surfaces of the rotating bodies 17 was 11mm were the best when the beauty device 10 was for a face. Next, the results of example 40 in which the distance D between the outer peripheral surfaces of the rotating bodies 17 was 8mm, example 41 in which the distance D was 10mm, and example 43 in which the distance D was 12mm were also good. It is also determined that the results of examples 39 and 44 in which the distance D between the outer peripheral surfaces of the rotating bodies 17 was 6mm and 15mm were acceptable.

Therefore, it was confirmed that when the beauty device 10 is used on the face, the distance D between the outer peripheral surfaces of the rotating bodies 17 is preferably in the range of 6 to 15mm, and more preferably in the range of 8 to 12 mm.

(examples 45 to 51 evaluation of diameter L of rotating body 17)

The diameter L of the rotating body 17 was evaluated for the cosmetic device 10 mainly applied to the body. That is, the diameter L of the rotating body 17 was evaluated by changing the diameter L of the rotating body 17 from 30mm to 60mm with the side projection angle α of the cosmetic device 10 set to 97 degrees, the opening angle β of the rotating body 17 set to 70 degrees, and the interval D between the outer peripheral surfaces of the rotating bodies 17 set to 11 mm. The evaluation method was performed in the same manner as in example 1 described above. The results obtained are shown in Table 7.

As shown in Table 7, the results of example 50 in which the diameter L of the rotating body 17 was 50mm and example 51 in which the diameter L was 60mm were the best. The results of example 48 in which the diameter L of the rotor 17 was 38.3mm and example 49 in which the diameter L of the rotor 17 was 40mm were also good. Furthermore, the results of examples 45 to 47 in which the diameter L of the rotating body 17 was 30 to 35mm were also judged as acceptable.

Therefore, it has been confirmed that when the cosmetic device 10 is used for a living body, the diameter L of the rotating body 17 is preferably in the range of 30 to 60mm, more preferably in the range of 38.3 to 60 mm.

(examples 52 to 58, evaluation of the distance D between the outer peripheral surfaces of the rotating bodies 17)

The distance D between the outer peripheral surfaces of the rotating bodies 17 was evaluated for the beauty treatment device 10 mainly applied to the body. That is, the evaluation of the distance D between the outer peripheral surfaces of the rotating bodies 17 was performed by changing the distance D between the outer peripheral surfaces of the rotating bodies 17 from 8mm to 25mm with the side projection angle α of the cosmetic device 10 set to 97 degrees, the opening angle β of the rotating bodies 17 set to 70 degrees, and the diameter L of the rotating bodies 17 set to 40 mm. The evaluation method was performed in the same manner as in example 1 described above. The results obtained are shown in Table 8.

As shown in Table 8, the results of examples 55 and 56 in which the distance D between the outer peripheral surfaces of the rotating bodies 17 was 12mm and 15mm were the best. The results of examples 53, 54, 57, and 58 in which the distance D between the outer peripheral surfaces of the rotating bodies 17 was 10 to 11mm were also good. The result of example 52, in which the distance D between the outer peripheral surfaces of the rotating bodies 17 was 8mm, was also judged to be acceptable.

Therefore, it was confirmed that when the beauty device 10 is used for the body, the distance D between the outer peripheral surfaces of the rotating bodies 17 is preferably in the range of 8 to 25mm, and more preferably in the range of 10 to 25 mm.

In consideration of the results of the above examples 1 to 58, it is determined that the side projection angle α of the cosmetic device 10 needs to be 90 to 110 degrees, preferably 93 to 100 degrees, and particularly preferably 95 to 99 degrees. And the opening angle beta of the rotating body 17 is preferably 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees. The diameter L of the rotating body 17 is preferably 15 to 60mm, more preferably 32 to 55mm, and particularly preferably 38 to 45 mm. The interval D between the outer peripheral surfaces of the rotating bodies 17 is preferably 8 to 25mm, more preferably 9 to 15mm, and particularly preferably 10 to 13 mm.

The above embodiment can be modified and embodied in the following manner.

As shown in fig. 8 and 9, the rotary body 17 may be formed in a balloon (balloon) shape in which the curvature of the outer peripheral surface of the rotary body 17 on the handle 11 side is larger than the curvature of the distal end side of the rotary body support shaft 15. In the case of such a configuration, the skin is pulled up by the portion having a small curvature, and the pulled-up state is maintained by the portion having a large curvature, so that the pulling-up effect of the skin 20 when the rotating body 17 is reciprocated can be improved.

The handle 11 and the two-leg portion 11a thereof are configured to be rotatable so that the side projection angle α of the axis y of the rotating body 17 with respect to the center line x of the handle 11 can be changed. In this case, the angle of the axis y of the rotating body 17 with respect to the skin 20 can be easily changed, and the convenience of use can be improved.

The shape of the rotating body 17 can be appropriately changed to an elliptical cross section, an oblong cross section, or the like.

Magnets are embedded in the outer periphery of the rotating body 17, and the magnetic force promotes blood flow to the skin 20.

A photocatalyst such as titanium oxide is embedded in the outer periphery of the rotating body 17, and dirt is prevented from adhering to the muscle surface or oxidized.

Alumina-based or zirconium-based ceramics that emit far infrared rays are provided in the rotating body 17, and far infrared rays are irradiated to the skin 20.

Instead of the solar cell panel 24, a dry cell may be used.

The upper handle cover 13a and the lower handle cover 13b can be formed of a conductive resin in which conductive powder such as carbon black metal is dispersed in a synthetic resin, without conductive plating of the upper handle cover 13a and the lower handle cover 13 b.

As the electrical insulating material forming the base 12, the handle cover 13, and the like of the handle 11, synthetic resins such as acrylic resin and polypropylene resin may be used in addition to nylon resin and ABS resin.

The shape of the surface 17a of the rotating body 17 may be a polygon or a circle other than a triangle. Further, on the surface 17a, a longitudinal stripe pattern, a lateral stripe pattern, a spiral stripe pattern, a satin surface finish pattern, a non-pattern, or the like may be formed.

The permanent magnet 22 and/or the solar cell panel 24 may be omitted.

The shape of the handle 11 may be changed. For example, the shape is changed to a cylindrical shape, a prismatic shape, or the like. In this case, the side projection angle α is an angle with respect to the axis of the handle 11. In addition, the shape of the grooves may be changed to a convex-concave shape, a gourd-shaped shape, or the like.

The bearing member 19 may be formed of a conductive resin.
