Description

  The present invention relates to a cosmetic device which can realize a beautiful skin by promoting blood flow or the like by massaging the skin of the face, arms and the like with a massage ball provided on a handle.

  Heretofore, various cosmetic devices of this type have been proposed. For example, Patent Document 1 discloses a skin beautifying roller. That is, the skin care 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 form an acute angle with the center line in the long axis direction of the handle. Furthermore, the angle between the rotation axes of the pair of rollers is set to be an obtuse angle. Then, when the handle of this skin smoothing roller is grasped by hand and the roller is pressed in one direction against the skin, the skin is pulled and the pores are opened, and when pulled while being pressed, the skin is sandwiched between the rollers and the pores Shrinks. Therefore, according to the skin care roller, it is possible to efficiently remove the dirt on the pores.

JP, 2009-142509, A

  However, in the skin care roller of the conventional configuration described in Patent Document 1, since the center line of the handle and the rotation axis of both the rollers are on one plane (see FIG. 2 of Patent Document 1), When holding by hand and pressing both rollers against the skin, the elbow should be raised, the wrist should be bent so that the hand points to the skin side, and the handle should stand upright against the skin. For this reason, there is a problem that the operation of the roller on the skin is largely changed depending on the wrist angle, in addition to the poor operability of the skin-removing roller.

  In addition, since each roller of this skin smoothing roller is formed in an elliptical cylindrical shape, when the roller is pressed in one direction, a wide portion of the skin is uniformly pressed, so that the opening of the pores is sufficiently obtained. I can not. Furthermore, when the rollers are pulled in the reverse direction, the skin located between the two rollers is pulled in an area corresponding to the length of the rollers, so it is difficult for the two rollers to pinch strongly. As a result, there is a problem that the opening and contraction of the pores are not sufficiently performed, and the dirt of the pores can not be removed cleanly. In addition, since the roller is formed in an elliptic cylindrical shape, the resistance against the skin is large due to line contact with the skin, the movement is not smooth, and the moving direction is likely to be restricted. Therefore, there existed a problem that the operativity of a skin care roller was bad.

  The present invention has been made focusing on the problems existing in such conventional techniques, and the object of the present invention is to be able to exert an excellent massage effect on the skin and to press the skin. An object of the present invention is to provide a cosmetic device which can exhibit the effect and the picking effect remarkably continuously, and has a good operability.

  In order to achieve the above object, the invention of a cosmetic device according to claim 1 is a cosmetic wherein a pair of balls are supported at the tip of the handle so as to be rotatable about the axis of the support shaft at mutually spaced intervals. , The axis of the ball is inclined forward with respect to the center line of the handle so that the axis of the ball can be maintained at a constant angle to the skin surface during reciprocation, and the opening angle of the pair of support axes is The ball has a hole for inserting a support shaft only on the base end side and has a non-penetrating state and is supported by the support shaft via a bearing member, pressing the outer peripheral surface of the ball against the skin It is characterized in that the skin can be picked up by moving in the proximal direction from the tip of the handle.

According to the cosmetic device of the present invention, the following effects can be exhibited.
In the cosmetic device according to claim 1, a pair of balls are rotatably supported at respective ends of the handle at mutually spaced intervals about the axis of the support shaft, and the axis of the ball is on the skin surface during reciprocation. The axis of the ball is inclined forward with respect to the center line of the handle so that a constant angle can be maintained. For this reason, it is not necessary to bend the wrist when holding the handle and applying a pair of balls to the skin, and while the wrist is straightened, the skin can be pressed when the cosmetic device is moved forward and beauty You can pick up the skin when you move the bowl back.

  In addition, since the portion in contact with the skin is not a cylindrical roller but a perfect circular ball, the ball contacts the skin locally. Therefore, the ball can concentrate on a local part of the skin to exert pressing force and picking force, can smoothly move the ball with respect to the skin, and has high freedom in the moving direction.

  Therefore, according to the cosmetic device of the present invention, an excellent massage effect can be exerted on the skin, and a pressing effect and a picking effect on the skin can be significantly and continuously exhibited, and operability The effect is good.

EMBODIMENT OF THE INVENTION Below, embodiment of the cosmetics device which actualized this invention is described according to FIGS. 1-7.
As shown in FIG. 1, a bifurcated portion 11 a extending in a flat Y-shape is provided at the tip of the handle 11 constituting the cosmetic device 10 of the present embodiment. As shown in FIG. 6, the handle 11 includes an electrically insulating base material 12 formed of a synthetic resin such as ABS resin, and an upper handle cover 13a and a lower handle cover coated on the outer periphery of the base material 12. It is comprised by the handle cover 13 which consists of 13b. The upper handle cover 13a and the lower handle cover 13b are each formed of a synthetic resin, and the outer surface is plated with a conductive layer, and both handle covers 13 are connected to the base 12 by a plurality of screws 14 ing.

  As shown in FIG. 7, at the bifurcated portion 11a of the handle 11, a pair of support cylinders 16 are integrally formed on the base material 12, and a metal ball support shaft 15 is supported on the support cylinders 16 . A cylindrical cap 18 made of synthetic resin is fitted around the tip outer periphery of the bifurcated portion 11 a of the handle 11. By fitting the cap 18, the tip of the forked portion 11a is sealed, and rattling of the ball support shaft 15 is prevented, and conduction between the outer surface of the forked portion 11a and the outer surface of the ball 17 described later Electrical insulation between parts is secured.

  A cylindrical bearing member 19 made of a synthetic resin and plated with metal on the inner and outer peripheries is fitted to the projecting end of the ball support shaft 15 and is fixed by a stop ring 25 so as to prevent it from coming off. A pair of elastically deformable locking claws 19 a is provided on the outer periphery of the bearing member 19 in a protruding manner. A spherical ball 17 is rotatably inserted into and supported by the bearing member 19 on the ball support shaft 15. The ball 17 is made of a core 26 made of a synthetic resin, a cap 27 made of a synthetic resin fitted on the inner periphery of the tip of the core 26, and a synthetic resin formed on the outer periphery of the core 26. It is comprised with the outer covering material 28.

  The outer surface of the outer covering material 28 is plated with conductive metal as a conductive portion, and is electrically connected to the metal plating of the bearing member 19. A stepped portion 26 a engageable with the locking claw 19 a of the bearing member 19 is formed on the inner periphery of the core 26. Then, in a state in which the ball 17 is inserted into the bearing member 19, the locking claw 19 a is engaged with the step portion 26 a, and the ball 17 is retained and held from the bearing member 19. Further, as shown in FIG. 3 and FIG. 4, on the outer peripheral surface of each ball 17, a large number of surfaces 17 a which stimulate the tissue of the skin 20 are formed.

  Inside each of the balls 17, a permanent magnet 22 for generating power as the balls 17 rotate is disposed. The permanent magnet 22 is cylindrically formed of magnet steel and is configured to be rotatable integrally with the ball 17. Then, with the rotation of the ball 17, the permanent magnet 22 is rotated relative to the ball support shaft 15 with a slight gap, so that fine irregularities or slight deviation of roundness on the surface of the ball support shaft 15 can be obtained. Micropower is generated as a result of this and so on, and the micropower is transmitted to the conductive portion of the outer peripheral surface of the ball 17.

  As shown in FIGS. 2 and 6, a transparent plate 23 is provided on the tip end side of the handle 11, that is, on the root side of the bifurcated portion 11a, and a solar cell panel 24 is installed inside thereof. The output terminal not shown is connected to the handle 11 and the conductive portion of the ball 17. For this reason, the electric power generated by the solar cell panel 24 is supplied to the handle 11 and the conductive portion of the ball 17. Therefore, when the cosmetic device 10 is used, the electricity of the solar cell panel 24 between the handle 11 and the ball 17 flows through the human body, and a cosmetic effect can be obtained.

The cosmetic device 10 of the present embodiment can be applied to the face as described above, and can also be applied to other bodies such as the neck, arms and legs.
As shown in FIG. 3, the axis of the ball support shaft 15 is at the center line x of the handle 11 so that the axis of the ball support shaft 15 can maintain a constant angle with respect to the skin 20 surface during reciprocation of the cosmetic device 10. It is configured to lean forward. Specifically, the axis y of the ball 17 with respect to the center line of the handle 11 (a line parallel to a line bisecting the angle between the outer peripheral tangent z of the thickest portion of the handle 11) x, ie, the axis y of the ball support shaft 15 Is preferably 90 to 110 degrees so that the ball 17 tilts forward with respect to the center line x of the handle 11 to improve operability. The side projection angle α is more preferably 93 to 100 degrees, and most preferably 95 to 99 degrees. When the side projection angle α is smaller than 90 degrees and larger than 110 degrees, the anteversion angle of the ball support shaft 15 becomes too small or too large, and when the ball 17 is applied to the skin 20, the elbow is raised. It is necessary to lower or bend the wrist greatly, so that the operability of the cosmetic device 10 is deteriorated, and it becomes difficult to adjust the angle of the ball support shaft 15 with respect to the surface of the skin 20.

  As shown in FIG. 5, the opening angle of the pair of balls 17, that is, the opening angle β of the pair of ball support shafts 15 is such that the pressing effect on the skin 20 and the picking effect are well expressed by the reciprocation of the balls 17. It is preferably set to 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees. If the opening angle β is less than 50 degrees, the picking effect on the skin 20 tends to be too strong, which is not preferable. On the other hand, when the opening angle β exceeds 110 degrees, it is difficult to pick up the skin 20 located between the balls 17, which is not preferable.

  The diameter L of each ball 17 is preferably set to 15 to 60 mm, more preferably 32 to 55 mm, particularly preferably 38 to 45 mm, in order to apply the cosmetic device 10 mainly to the face and arms. If the diameter L of the ball 17 is smaller than 15 mm, the range of the skin 20 where the pressing effect and the picking effect can be expressed becomes narrow, which is not preferable. On the other hand, when the diameter L of the ball 17 is larger than 60 mm, it is difficult to press or pick up a narrow portion because the size of the ball 17 is relatively large with respect to the size of the face or arm. It becomes inconvenient.

  Furthermore, the distance D between the outer peripheral surfaces of the balls 17 is preferably 8 to 25 mm, more preferably 9 to 15 mm, particularly preferably 10 to 13 mm, in particular, in order to appropriately pick up the skin 20. When the distance D between the outer peripheral surfaces of the balls 17 is less than 8 mm, the pick-up effect is not preferable because the skin 20 located between the balls 17 is too strong in picking effect. On the other hand, when the distance D between the outer peripheral surfaces of the balls 17 exceeds 25 mm, it is difficult to pick up the skin 20 located between the balls 17, which is not preferable.

Next, the operation of the cosmetic device 10 of the embodiment configured as described above will be described.
Now, when using this cosmetic device 10, as shown in FIG. 3, with the user holding the handle 11, the outer surface of the ball 17 is shown on the skin 20 such as a face or an arm shown by a two-dot chain line in FIG. When it is moved forward from the base end of the handle 11 in the distal direction (left direction in FIG. 3) while being pressed and in contact, the ball 17 is rotated about the ball support shaft 15. At this time, as shown by a two-dot chain line in FIG. When the ball 17 is moved forward and then moved back so that the ball 17 is returned, the skin 20 located between the balls 17 is picked up along with the rotation of the balls 17 as shown by the two-dot chain line in FIG. Be

  That is, as shown in FIG. 5, when both balls 17 move forward in the arrow P1 direction, each ball 17 is rotated in the arrow P2 direction. For this reason, the skin 20 is pressed to be spread. On the other hand, when both balls 17 are moved back in the direction of arrow Q1, each ball 17 is rotated in the direction of arrow Q2. Therefore, the skin 20 located between the balls 17 is picked up so as to be rolled up. Note that when the balls 17 press the skin 20 during the forward movement, the skin 20 between the balls 17 is picked up as a reaction of the pressing force.

  In this case, the ball support shaft 15 is inclined forward with respect to the center line x of the handle 11. Specifically, the side projection angle α of the ball support shaft 15 with respect to the center line x of the handle 11 is 90 to 110 degrees. Since it is set, the reciprocation operation of the cosmetic device 10 can be performed without raising the elbow or bending the wrist too much. Moreover, the operation can be continued while keeping the axis y of the ball support shaft 15 close to the surface of the skin 20 at a right angle. Therefore, it is possible to effectively press the ball 17 against the skin 20 to express the massage action efficiently.

  Further, since the portion in contact with the skin 20 is not a conventional cylindrical roller, but is constituted by a round ball 17, the ball 17 contacts the skin 20 in a smaller area than the roller. Therefore, the ball 17 can be concentrated on a local part of the skin 20 to exert pressing force and picking force, and at the same time the movement of the ball 17 with respect to the skin 20 is smooth and the movement direction can be easily changed. .

  Therefore, the pressing force accompanying the rotation of the ball 17 massages the skin 20 such as the face and the arm to promote blood flow in that portion and also promote circulation of lymph fluid. In addition, the opening angle β of the pair of balls 17 is set to 50 to 110 degrees, and the distance D between the outer peripheral surfaces of the balls 17 is set to 8 to 25 mm. While pressing the skin 20 can be applied, the skin 20 can be picked comfortably without being too strong or too weak. Furthermore, since the diameter L of the ball 17 is set to 15 to 60 mm, it is possible to appropriately cope with the face and the arm, and the operation of the cosmetic device 10 can be advanced promptly. For this reason, for example, a lift-up massage can be performed as desired on a slack portion of the skin 20.

  In addition, when the skin 20 is pulled by the pressing force of the ball 17, the pore is opened, and when the skin 20 is picked up between the balls 17, the pore is contracted and the dirt in the pore is removed. Furthermore, since the user's skin 20 is in contact with the outer peripheral surface of the ball 17 and the user's hand is in contact with the conductive portion on the surface of the handle 11, the power generated by the solar cell panel 24 As shown in FIG. 3, a weak current flows from the ball 17 through the skin 20 and the user's hand to stimulate the skin 20, thereby promoting blood flow and circulation of lymph fluid. Therefore, these massage action, pressing / picking action, lift-up action, pore dirt removal action, electrical stimulation action, etc. act synergistically and complexly on the skin 20, and a desirable skin care action is exhibited. .

Therefore, according to this embodiment, the following effects can be obtained.
(1) In the cosmetic device 10 of the present embodiment, the pair of balls 17 are rotatably supported about each axis y with an interval therebetween, and the ball support shaft 15 is inclined forward with respect to the center line x of the handle 11 Thus, the side projection angle α of the axis y of the ball 17 with respect to the center line x of the handle 11 is set to 90 to 110 degrees. That is, since the axis y of the ball 17 is inclined forward with respect to the center line x of the handle 11, the elbow is raised by holding the handle 11 and the pair of balls 17 hit the skin 20 or the wrist There is no need to bend. Therefore, the cosmetic device 10 can be easily reciprocated to press and pick up the skin 20.

  In addition, since the portion in contact with the skin 20 is constituted by the round ball 17, pressing force and picking force can be intensively applied to a desired part of the skin 20, and the ball 17 against the skin 20 is Smooth movement and high freedom of movement direction.

  Therefore, according to the cosmetic device 10 of the present embodiment, an excellent massage effect can be exerted on the skin 20, and the pressing effect and the picking effect on the skin 20 can be significantly and continuously exhibited. And, the effect that the operability is good can be exhibited.

  (2) The side projection angle α of the axis y of the ball 17 is preferably 93 to 100 degrees, more preferably 95 to 99 degrees, thereby further improving the cosmetic effects such as the operability and the massage effect of the cosmetic device 10 It can be done.

  (3) When the opening angle β of the pair of balls 17 is preferably 50 to 110 degrees, more preferably 50 to 90 degrees, particularly preferably 65 to 80 degrees, the pressing effect and picking effect of the cosmetic device 10 can be obtained. It can be improved dramatically.

  (4) When the diameter L of the ball 17 is preferably 15 to 60 mm, more preferably 32 to 55 mm, particularly preferably 38 to 45 mm, the cosmetic device 10 can be suitably applied to the face and arms , Massage effect and operability can be enhanced.

  (5) Preferably, the distance D between the outer peripheral surfaces of the balls 17 is 8 to 25 mm, more preferably 9 to 15 mm, and particularly preferably 10 to 13 mm, to obtain an appropriate pressing effect on the desired skin 20 site. At the same time, the skin 20 can be picked up comfortably with a moderate strength.

  (6) In this beauty device 10, a power supply is comprised from the solar cell panel 24 provided in the handle 11. As shown in FIG. Therefore, it is not necessary to provide a power source such as a dry cell, and a weak current can be flowed from the ball 17 to the skin 20 by using the power generated by the solar cell panel 24.

  (7) In the cosmetics device 10 of this embodiment, the permanent magnet 22 for performing an electric power generation with rotation of the ball | bowl 17 is arrange | positioned. Therefore, micropower can be obtained based on the rotation of the ball 17, and the micropower can provide a weak current from the ball 17 to the skin 20.

Therefore, when the cosmetic device 10 is for body use, the diameter L of the ball 17 is preferably in the range of 30 to 60 mm, and more preferably in the range of 38.3 to 60 mm.
(Examples 52 to 58, evaluation of distance D between outer peripheral surfaces of balls 17)
The distance D between the outer circumferential surfaces of the balls 17 was evaluated for the cosmetic device 10 suitable mainly for the body. That is, the distance D between the outer peripheral surfaces of the balls 17 is changed to 8 to 25 mm by setting the side projection angle α of the cosmetic device 10 to 97 degrees, the opening angle β of the balls 17 to 70 degrees and the diameter L of the balls 17 to 40 mm. The distance D between the outer peripheral surfaces of the balls 17 was evaluated. The evaluation method was the same as in Example 1 above. The obtained results are shown in Table 8.

  As shown in Table 8, the results of Example 55 with the distance D between the outer peripheral surfaces of the balls 17 of 12 mm and Example 56 with 15 mm were the best. Next, the results of Examples 53, 54 and 20 to 25 mm, in which the distance D between the outer peripheral surfaces of the balls 17 was 10 to 11 mm, were good. Furthermore, it was determined that the result of Example 52 in which the distance D between the outer peripheral surfaces of the balls 17 was 8 mm was also possible.

Therefore, when the cosmetic device 10 is for body use, the distance D between the outer peripheral surfaces of the balls 17 is preferably in the range of 8 to 25 mm, and more preferably in the range of 10 to 25 mm.
Taking together the results of Examples 1 to 58 shown above, the side projection angle α of the cosmetic device 10 needs to be 90 to 110 degrees, preferably 93 to 100 degrees, particularly 95 to 99 degrees. It was judged to be preferable. The opening angle β of the ball 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 ball 17 is preferably 15 to 60 mm, more preferably 32 to 55 mm, and particularly preferably 38 to 45 mm. The distance D between the outer peripheral surfaces of the balls 17 is preferably 8 to 25 mm, more preferably 9 to 15 mm, and particularly 10 to 13 mm.

In addition, it is also possible to change and implement the said embodiment as follows.
As shown in FIGS. 8 and 9, the ball 17 is formed in a balloon shape so that the curvature on the handle 11 side of the outer peripheral surface of the ball 17 is larger than the curvature on the tip side of the ball support shaft 15 It can also be done. In such a configuration, the skin can be picked up at a portion with a small curvature, and the picked up state can be maintained at a portion with a large curvature, so that the picking effect of the skin 20 when moving the ball 17 back is improved. be able to.

  In order to make the side projection angle α of the axis y of the ball 17 with respect to the center line x of the handle 11 variable, it is also possible to pivot between the handle 11 and its fork 11a. In this case, the angle of the axis y of the ball 17 with respect to the skin 20 can be easily changed, and the usability can be improved.

It is also possible to appropriately change the shape of the ball 17 into an oval cross-sectional shape, an oval cross-sectional shape, or the like.
A magnet may be embedded in the outer peripheral portion of the ball 17 so as to promote blood flow to the skin 20 by its magnetic force.

A photocatalyst such as titanium oxide may be embedded in the outer peripheral portion of the ball 17 to suppress adhesion of dirt to the skin surface or oxidize dirt.
The ball 17 may be configured to include an alumina-based or zirconium-based ceramic that emits far-infrared radiation so that the skin 20 may be exposed to far-infrared radiation.

It is also possible to use a dry cell instead of the solar cell panel 24.
The conductive plating of the upper handle cover 13a and the lower handle cover 13b is omitted, and the upper handle cover 13a and the lower handle cover 13b are conductive by dispersing conductive powder such as carbon black or metal in a synthetic resin. It can be formed of a resin.

  As the electric insulating material for forming the base 12 of the handle 11, the handle cover 13 and the like, synthetic resins such as acrylic resin and polypropylene resin can be used besides nylon resin and ABS resin.

  The shape of the surface 17 a of the ball 17 may be formed into a polygon other than a triangle or a circle. Also, the surface 17a can be formed to have a vertical stripe pattern, a horizontal stripe pattern, a swirl stripe pattern, a textured pattern, no pattern, or the like.

The permanent magnet 22 and the solar cell panel 24 may be omitted.
The shape of the handle 11 can also be changed. For example, it can be changed to a cylindrical shape, a cylindrical shape, a prismatic shape or the like. In that case, the side projection angle α is an angle to the axis of the handle 11. In addition, it is also possible to change it to uneven shape, gourd shape, etc.

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