Description

  The present invention relates to a cosmetic device that can realize beautiful skin by promoting blood flow by massaging skin such as a face and arms with a massage ball provided on a handle.

  Conventionally, various types of beauty devices have been proposed. For example, Patent Document 1 discloses a skin beautifying roller. That is, this skin-beautifying 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 so as to form an acute angle with the center line in the major axis direction of the handle. Further, the angle formed by the rotation shafts of the pair of rollers is set to be an obtuse angle. And if you hold the handle of this beautiful skin roller by hand and press the roller in one direction against the skin, the skin will be pulled and pores will open, and if you press and pull in the opposite direction, the skin will be pinched between the rollers and the pores Contracts. Therefore, according to the skin beautifying roller, dirt on pores can be efficiently removed.

JP 2009-142509 A

  However, in the beautifying roller having the conventional configuration described in Patent Document 1, since the center line of the handle and the rotation axis of both rollers are on one plane (see FIG. 2 of Patent Document 1), the handle of the beautifying roller is When holding both hands and pressing both rollers against the skin, the elbow must be raised and the wrist must be bent so that the tip of the hand faces the skin, so that the handle must stand upright against the skin. For this reason, there are problems that the operability of the skin beautifying roller is poor and the action state of the roller on the skin greatly changes depending on the wrist angle.

  In addition, since each roller of this skin beautifying roller is formed in an elliptical cylindrical shape, when the roller is pressed in one direction, a wide portion of the skin is pressed uniformly, so that pores can be sufficiently opened. I can't. Further, when the rollers are pulled in the opposite direction, the skin located between the two rollers is pulled in a region corresponding to the length of the rollers, and thus is not easily pinched between the two rollers. As a result, there was a problem that pores were not sufficiently opened and contracted, and dirt on pores could not be removed cleanly. In addition, since the roller is formed in an elliptical cylindrical shape, the line is in contact with the skin, resistance to the skin is large, the movement is not smooth, and the moving direction is easily limited. Therefore, there is a problem that the operability of the skin beautifying roller is poor.

  This invention was made paying attention to the problem which exists in such a prior art, The place made into the objective can have the outstanding massage effect with respect to skin, and is a press with respect to skin. An object of the present invention is to provide a cosmetic device that can exhibit the effect and the picking effect remarkably continuously and has good operability.

  In order to achieve the above object, the cosmetic device according to claim 1 is a cosmetic device in which a pair of balls are supported on the front end side of the handle so as to be rotatable about the axis of the support shaft at intervals. The instrument is characterized in that the axis of the support shaft faces the distal end side and the lower side of the handle in a side view of the cosmetic device, and the ball has a non-penetrating shape covering the distal end of the support shaft.

According to the cosmetic device of the present invention, the following effects can be exhibited.
The cosmetic device according to claim 1, wherein a pair of balls are supported at the distal end side of the handle so as to be rotatable about the axis of the support shaft at a distance from each other. The axis of the head faces the front end side and the lower side of the handle. For this reason, it is not necessary to bend the wrist when gripping the handle and hitting a pair of balls against the skin, and the skin can be pressed when the cosmetic device is moved forward with the wrist straightened. The skin can be picked up when the container is moved back.

  Moreover, since the part which contacts skin is comprised not by the cylindrical roller but by the perfect circle | round | yen ball | bowl, a ball | bowl contacts locally with respect to skin. Therefore, the ball can concentrate on the local area of the skin and act on the pressing force and the picking force, and can smoothly move the ball with respect to the skin and has a high degree of freedom in the moving direction.

  Therefore, according to the beauty device of the present invention, an excellent massage effect can be exerted on the skin, and the pressing effect on the skin and the picking effect can be remarkably continuously exhibited, and the operability is improved. Can exhibit the effect of being good.

Embodiments of a cosmetic device embodying the present invention will be described below with reference to FIGS.
As shown in FIG. 1, a bifurcated portion 11 a extending in a plane Y shape is provided at the tip of a 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 13 a and a lower handle cover coated on the outer periphery of the base material 12. And a handle cover 13 made of 13b. Each of the upper handle cover 13a and the lower handle cover 13b is made of synthetic resin, and the outer surface thereof is subjected to conductive plating, and both the handle covers 13 are connected to the base material 12 by a plurality of screws 14. ing.

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

  A cylindrical bearing member 19 made of a synthetic resin and having a metal plating applied to the inner and outer circumferences is fitted to the protruding end of the ball support shaft 15, and is fixed by a stop ring 25. On the outer periphery of the bearing member 19, a pair of elastically deformable locking claws 19a project. A spherical ball 17 is rotatably inserted and supported on the bearing member 19 on the ball support shaft 15. The ball 17 is made of a core material 26 made of a synthetic resin, a cap material 27 made of a synthetic resin fitted on the inner periphery of the tip of the core material 26, and a synthetic resin coated on the outer periphery of the core material 26. The outer skin material 28 is comprised.

  Conductive metal plating as a conductive portion is applied to the outer surface of the outer skin material 28 and is electrically connected to the metal plating of the bearing member 19. On the inner periphery of the core member 26, a step portion 26 a that can be engaged with the locking claw 19 a of the bearing member 19 is formed. In a state where 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 held against the bearing member 19. As shown in FIGS. 3 and 4, a large number of surfaces 17 a that stimulate the tissue of the skin 20 are formed on the outer peripheral surface of each ball 17.

  Inside each of the balls 17, permanent magnets 22 for generating electric power as the balls 17 rotate are disposed. The permanent magnet 22 is formed in a cylindrical shape from magnetic steel, and is configured to rotate integrally with the ball 17. As the ball 17 rotates, the permanent magnet 22 is rotated relative to the ball support shaft 15 at a slight interval, so that fine irregularities on the surface of the ball support shaft 15 and a slight deviation in roundness are obtained. For example, a minute electric power is generated, and the minute electric power is transmitted to the conductive portion on the outer peripheral surface of the ball 17.

  As shown in FIGS. 2 and 6, a transparent plate 23 is provided on the distal end side of the handle 11, that is, the base side of the bifurcated portion 11a, and a solar cell panel 24 is installed on the inside thereof. (Not shown) are 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 conductive portions of the handle 11 and 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 necks, arms, and legs.
As shown in FIG. 3, the axis of the ball support shaft 15 is aligned with 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 the reciprocating operation of the cosmetic device 10. It is configured to tilt 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 that bisects the angle between the outer peripheral tangent lines z of the thickest portion of the handle 11), that is, the axis y of the ball support shaft 15 The side projection angle α is preferably 90 to 110 degrees so that the ball 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 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 forward tilt 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, Since it is necessary to lower or to bend the wrist greatly, the operability of the cosmetic device 10 is deteriorated and it is difficult to adjust the angle of the ball support shaft 15 with respect to the skin 20 surface.

  As shown in FIG. 5, the opening angle β of the pair of balls 17, that is, the opening angle β of the pair of ball support shafts 15, in order to express the pressing effect and picking effect on the skin 20 by the reciprocating motion of the balls 17, The angle 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 picking effect on the skin 20 tends to act too strongly, 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, and particularly preferably 38 to 45 mm in order to apply the cosmetic device 10 mainly to the face and arms. When the diameter L of the ball 17 is smaller than 15 mm, the range of the skin 20 in which the pressing effect and the picking up effect can be expressed is not preferable. On the other hand, when the diameter L of the ball 17 is larger than 60 mm, since the size of the ball 17 is relatively large with respect to the size of the face or arm, it is difficult to press or pick up a narrow portion, Usability is poor.

  Further, 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 preferably 10 to 13 mm in order to appropriately pick up the skin 20 in particular. When the distance D between the outer peripheral surfaces of the balls 17 is less than 8 mm, the picking effect is excessively exerted on the skin 20 located between the balls 17, which is not preferable. 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, an effect | action is demonstrated about the cosmetics device 10 of embodiment comprised as mentioned above.
Now, when the cosmetic device 10 is used, as shown in FIG. 3, the outer surface of the ball 17 is applied to the skin 20 such as the face and arms shown by the two-dot chain line in FIG. 3 while the user holds the handle 11. If the handle 11 is moved in the forward direction from the proximal end of the handle 11 (leftward in FIG. 3) while being pressed and contacted, the ball 17 is rotated about the ball support shaft 15. At this time, as shown by a two-dot chain line in FIG. 3, a pressing force is applied to the skin 20 from the ball 17. After the ball 17 is moved forward, when the ball 17 is moved back so as to return to the original position, the skin 20 located between the balls 17 is picked up as the ball 17 rotates as shown by a two-dot chain line in FIG. It is done.

  That is, as shown in FIG. 5, when both balls 17 are moved forward in the direction of arrow P1, each ball 17 is rotated in the direction of arrow P2. For this reason, the skin 20 is pressed so as 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. For this reason, the skin 20 located between the balls 17 is picked up so as to be rolled up. When both 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, and 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 cosmetic device 10 can be reciprocated without raising the elbow or bending the wrist too much. Moreover, the operation can be continued while maintaining the axis y of the ball support shaft 15 so as to be close to a right angle with respect to the skin 20 surface. Therefore, the ball 17 can be effectively pressed against the skin 20 and the massage action can be efficiently expressed.

  Moreover, since the part which contacts the skin 20 is comprised not of the conventional cylindrical roller but the perfect circle | round | yen ball | bowl 17, the ball | bowl 17 contacts the skin 20 in an area narrower than a roller. Therefore, the ball 17 can concentrate on the local area of the skin 20 to apply a pressing force and a picking force, and at the same time, the movement of the ball 17 with respect to the skin 20 is smooth and the moving direction can be easily changed. .

  Accordingly, the pressing force accompanying the rotation of the ball 17 massages the skin 20 such as the face, arms, etc., and promotes blood flow in the portion and circulation of lymph. Further, since 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, it is suitable for the desired skin 20 site. A simple pressing force can be applied, and the skin 20 can be picked up comfortably without being too strong and not 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 arms, and the operation of the cosmetic device 10 can be promptly advanced. For this reason, for example, lift-up massage can be performed as desired on a loosened portion of the skin 20.

  In addition, when the skin 20 is pulled by the pressing force of the balls 17, the pores open, and when the skin 20 is picked up between the balls 17, the pores contract and the dirt in the pores is removed. In addition, 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 is used. 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 lymph circulation. Therefore, these massage action, pressing / pick-up action, lift-up action, pore dirt removal action, electrical stimulation action, etc. work synergistically and complexly on the skin 20, and the desired skin beautifying action is exhibited. .

Therefore, according to this embodiment, the following effects can be obtained.
(1) In the cosmetic device 10 of the present embodiment, a pair of balls 17 are supported so as to be rotatable about the respective axes y with a space between each other, and the ball support shaft 15 is inclined forward with respect to the center line x of the handle 11. As described above, 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 tilted forward with respect to the center line x of the handle 11, when the handle 11 is gripped and the pair of balls 17 are applied to the skin 20, There is no need to bend. For this reason, the skin 20 can be pressed and picked up easily by reciprocating the beauty device 10.

  Moreover, since the part which contacts the skin 20 is comprised by the perfect circle-shaped ball 17, while pressing force and picking-up force can be made to concentrate on the desired location of the skin 20, the ball 17 with respect to the skin 20 can be applied. Can move smoothly and has a high degree of freedom in the direction of movement.

  Therefore, according to the beauty device 10 of this embodiment, while being able to show the outstanding massage effect with respect to the skin 20, the press effect with respect to the skin 20 and the picking-up effect can be exhibited notably continuously. And the effect that operativity is favorable can be exhibited.

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

  (3) The opening angle β of the pair of balls 17 is preferably 50 to 110 degrees, more preferably 50 to 90 degrees, and particularly preferably 65 to 80 degrees. It can be improved significantly.

  (4) Since 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 cosmetic device 10 can be suitably applied to the face and arms. , Can improve the massage effect and operability.

  (5) 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 preferably 10 to 13 mm, thereby obtaining an appropriate pressing effect on the desired skin 20 site. At the same time, the skin 20 can be picked up comfortably with moderate strength.

  (6) In this cosmetic device 10, the power source is constituted by a solar cell panel 24 provided on the handle 11. For this reason, it is not necessary to provide a power source such as a dry battery, and a weak current can be passed from the ball 17 to the skin 20 using the power generated by the solar cell panel 24.

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

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 the distance D between the outer peripheral surfaces of the balls 17)
The space D between the outer peripheral surfaces of the balls 17 was evaluated for the cosmetic device 10 mainly suitable for body use. That is, the side projection angle α of the cosmetic device 10 is 97 degrees, the opening angle β of the ball 17 is 70 degrees, the diameter L of the ball 17 is 40 mm, and the distance D between the outer peripheral surfaces of the balls 17 is changed from 8 to 25 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. The obtained results are shown in Table 8.

As shown in Table 8, the results of Example 55 in which the distance D between the outer peripheral surfaces of the balls 17 was 12 mm and Example 56 of 15 mm were the best. Next, the results of Example 53, Example 54, and Example 57 and Example 58 having a distance D between the outer peripheral surfaces of the balls 17 of 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.
Summing up 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, and particularly 95 to 99 degrees. It was judged 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 preferably 10 to 13 mm.

It should be noted that the embodiment described above can be modified and embodied as follows.
As shown in FIGS. 8 and 9, the shape of 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. You can also. 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 effect of picking up the skin 20 when the ball 17 is moved 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 configure the handle 11 and its bifurcated portion 11a to be rotatable. In this case, the angle of the axis y of the ball 17 with respect to the skin 20 can be easily changed, and usability can be improved.

The shape of the ball 17 can be appropriately changed to an elliptical cross section, an oval cross section, or the like.
A magnet may be embedded in the outer peripheral portion of the ball 17 so that blood flow is promoted with respect to the skin 20 by the magnetic force.

It is possible to embed a photocatalyst such as titanium oxide around the outer periphery of the ball 17 to suppress the adhesion of dirt to the skin surface or to oxidize dirt.
The ball 17 may be configured to include far-infrared rays on the skin 20 by including an alumina-based or zirconium-based ceramic that emits far-infrared rays.

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

  As the electrically insulating material for forming the base material 12 and the handle cover 13 of the handle 11, a synthetic resin such as an acrylic resin and a polypropylene resin can be used in addition to nylon resin and ABS resin.

  The shape of the surface 17a of the ball 17 can be formed into a polygon other than a triangle or a circle. Further, the surface 17a can be formed in a vertical stripe pattern, a horizontal stripe pattern, a swirl stripe pattern, a satin pattern, no pattern, or the like.

-The permanent magnet 22 and the solar cell panel 24 can be omitted.
The shape of the handle 11 can be changed. For example, the shape can be changed to a cylindrical shape, a columnar 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, it is also possible to change the shape to an uneven shape, a gourd shape, or the like.

  The bearing member 19 can be made of a conductive resin.
