  The present invention relates to a cosmetic device used for the beauty of various parts of the body.

  2. Description of the Related Art A cosmetic device that is used by rotating a roller while pressing it against the skin is known for skin beauty. This type of beauty device has a main body portion that has a bifurcated shape and a roller that is attached to the tip of the main body portion, and is used by sandwiching each part of the user's body between a pair of rollers. There is a beauty device (for example, Patent Document 1). As an example of such a cosmetic device, Patent Document 1 discloses a pair of sub handle portions in which a pair of rollers is rotatably supported at the tip, and a connecting portion that connects the other ends of the pair of sub handle portions to each other. A cosmetic device with a handle having a handle is disclosed. In the configuration of Patent Document 1, the pair of sub-handle portions are supported so as to be able to be opened and closed within a predetermined range in the connecting portion, and the pair of sub-handle portions are elastically deformed to rotate. It can be opened beyond the range of motion. Furthermore, the cosmetic device disclosed in Patent Document 1 includes a biasing member that biases the pair of sub handle portions so that the open / closed state of the pair of sub handle portions is returned to the initial state.

Japanese Patent Laying-Open No. 2015-163177

  However, in the configuration disclosed in Patent Document 1, the pair of sub handle portions are configured to rotate at individual rotation fulcrums in the connecting portion. Therefore, when gripping and using a pair of sub handle parts collectively, it is difficult to adjust the relative force in the pair of sub handle parts, and the skin surface may not be picked up sufficiently. In addition, since it is necessary to generate an urging force for returning the pair of sub handle portions to the initial state in consideration of the rotation of the pair of sub handle portions at individual rotation fulcrums, the design of the urging member is required. The degree of freedom was reduced.

  The present invention has been made in view of such a background, and an object of the present invention is to provide a cosmetic device capable of improving the beauty effect.

One aspect of the present invention is a handle including a pair of sub-handle portions and a connecting portion that connects the pair of sub-handle portions so as to be openable and closable.
Shaft portions respectively supported by the pair of sub handle portions;
A roller disposed on the shaft and supported rotatably about the axis of the shaft;
An urging member that generates an urging force for returning the relative positional relationship of the pair of sub-handle portions to the initial state,
The connecting portion has one rotation fulcrum,
The pair of sub handle portions are in a cosmetic device configured to open and close by rotating about the rotation fulcrum.

  In the cosmetic device, the pair of sub-handle portions are connected by the connecting portion so as to rotate around a single rotation fulcrum of the connecting portion to open and close. Thereby, compared with the case where a pair of sub handle part rotates by a separate rotation fulcrum, adjustment of the relative force adjustment in a pair of sub handle part becomes easy. As a result, it becomes easier to pick up the skin surface, and the beauty effect is improved. In addition, the biasing force for returning the pair of sub handle portions to the initial state does not need to consider that the pair of sub handle portions rotate at individual rotation fulcrums. Is prevented.

  Further, the pair of sub handle portions support the shaft portions of the pair of rollers and are connected so as to be openable and closable. As a result, the user can spread the pair of sub handle portions by pressing the pair of rollers against the part where the cosmetic effect is desired to be obtained, and appropriately adjust the distance between the pair of rollers according to the shape of the part to be used. it can. As a result, the cosmetic device can be suitably used from a relatively large undulating portion such as the face or arm to a relatively small undulating portion such as the abdomen.

  Moreover, the said cosmetics device can adjust easily the pressing force applied to the part which wants to obtain a cosmetic effect by adjusting the opening / closing degree of a pair of sub handle part by a user. Therefore, the cosmetic device is easy to handle. In addition, the pressing force of the pair of rollers can be expected to promote the blood circulation of the pressed part, activate the metabolism, and the like, and thus an excellent cosmetic effect such as beautifying the skin can be expected.

  The cosmetic device includes a biasing member that generates a biasing force for returning the relative positional relationship between the pair of sub handle portions to an initial state. As a result, in a state where the pair of sub handle portions rotate in the opening direction and the distance between the pair of rollers is widened, the biasing force by the biasing member acts on each roller so that the pair of rollers approaches each other. Be forced. Therefore, a moderately large pressing force can be applied to the portion sandwiched between the pair of rollers. As a result, a better beauty effect can be expected.

  As described above, according to the present invention, it is possible to provide a cosmetic device that can improve the cosmetic effect.

  In the present specification, the “initial state” refers to a state where the cosmetic device is not used and a portion where a cosmetic effect is desired to be obtained is not sandwiched between a pair of rollers.

  It is preferable that the pair of sub handle portions include a twist preventing member that prevents the pair of sub handle portions from being twisted when rotating about the rotation fulcrum. When the pair of rollers are pressed against the skin surface and the pair of sub handle portions are deformed to be twisted, the inclination angle of the axis of the shaft portion supported by the pair of sub handle portions is changed. Accordingly, the skin surface cannot be sufficiently picked up by the pair of rollers supported by the shaft portion, and the beauty effect may be reduced. However, as described above, since the twist prevention member prevents the pair of sub handle portions from being deformed so as to be twisted, the inclination angle of the axis of the shaft portion supported by the pair of sub handle portions is maintained. The As a result, the skin surface can be sufficiently picked up by the pair of rollers, and a reduction in the beauty effect is prevented. As the torsion preventing member, various embodiments can be used as long as they have high rigidity.

  The pair of sub handle portions includes an outer surface forming portion that forms an outer surface of the pair of sub handle portions, and the twist preventing member is disposed inside the outer surface forming portion, and the outer surface forming portion. It is preferably made of a core material having higher rigidity. In this case, the core material as an anti-twisting member can prevent the pair of sub handle portions from being twisted to prevent a reduction in the beauty effect, and the outer surface forming portion can be formed into a shape that is easy for the user to hold, It is possible to increase the degree of freedom in designing such as a shape having high design properties.

  The shape and material of the core material can take various forms as long as the rigidity of the pair of sub handle portions in the torsional direction is sufficiently high. For example, the rigidity of the core material can be sufficiently increased by using a metal plate as the core material. Further, the rigidity of the core material can be further increased by using a metal plate having a relatively high strength such as a stainless steel plate or by increasing the plate thickness. Usually, by using a stainless steel plate as a core material, sufficient rigidity can be obtained, and twisting of the pair of sub handle portions can be prevented, thereby preventing a reduction in cosmetic effect.

  It is preferable that the core material is provided over half or more of the length in the longitudinal direction of the pair of sub handle portions in the longitudinal direction of the pair of sub handle portions. In this case, the rigidity of the pair of sub handle portions is increased, and the twist of the pair of sub handle portions can be further prevented.

  The pair of core members is more preferably provided over the entire pair of sub-handle portions in the longitudinal direction of the pair of sub-handle portions. In this case, the rigidity of the pair of sub handle portions can be further increased, and the pair of sub handle portions can be further prevented from being twisted.

  Each of the pair of core members has a through hole at an end thereof, and the rotation fulcrum of the connecting portion is configured such that the through holes of the pair of core members are stacked on the same axis, and the handle is provided in the through hole. It is preferable to be configured by inserting a shaft. In this case, the pair of sub handle portions can be rotated at one rotation fulcrum with a simple configuration.

  The core member is preferably provided with a shaft support portion that supports the shaft portion at an end portion opposite to the end portion where the through hole is provided. In this case, the user can change the distance between the pair of rollers by adjusting the degree of opening and closing of the pair of sub handle portions. Therefore, it becomes easy for the user to intuitively grasp the relationship between the magnitude of the opening / closing operation of the pair of sub handle portions and the amount of change in the distance between the pair of rollers. Further, by adjusting the degree of opening and closing of the pair of sub handle portions, it is possible to easily adjust the pressing force applied to the portion where the cosmetic effect is desired. As a result, it is possible to make the cosmetic device easier to handle and to expect a better cosmetic effect.

  In the initial state, the pair of shaft portions may be arranged so as to be in an expanded state in which the interval between the pair of axis lines increases from the base portion on the handle side toward the distal end side. In this case, when the cosmetic device is pressed against the skin, the distance between the pair of rollers can be easily increased. As a result, the cosmetic device is easier to handle for the user.

  Moreover, a spring member, rubber | gum, etc. can be used for the said urging | biasing member, for example. Of these, a metal spring member is preferably used as the biasing member. The metal spring member can easily increase the biasing force appropriately. Therefore, the use of the cosmetic device can be expected to have a better beauty effect.

  In the initial state, the pair of rollers may be separated from each other. In this case, when the pair of rollers is pressed against a portion where a cosmetic effect is desired to be obtained, it is possible to naturally realize a state where the portion is sandwiched between the rollers to some extent. Thereby, the operation | movement which pinches | interposes the part which wants to obtain the beauty effect between the said rollers can be performed more easily, and it becomes easier to handle for a user. In the initial state, when the pair of rollers are separated from each other, the distance between the pair of rollers in the initial state can be appropriately set within a range of 1 to 50 mm.

  Further, the pair of shaft portions may be arranged so as to be always in the expanded state. In this case, the pressing force experienced in the portion sandwiched between the pair of rollers can be increased moderately, an excellent cosmetic effect can be expected, and the ease of handling of the cosmetic device can be further improved.

  The handle is preferably inclined with respect to a plane including the pair of axes. In this case, the plane including the pair of axes is inclined with respect to the skin surface by pressing the pair of rollers against the skin surface so that the handle is along the skin surface. And the part which wants to obtain the beauty effect can be deformed so that it can pick up with a pair of roller by moving the said cosmetics device, maintaining this state. As a result, a better cosmetic effect can be expected by using the cosmetic device.

  Moreover, the effect | action which picks up the skin mentioned above changes with the space | interval of a pair of roller, and can maintain the said effect | action reliably by keeping the space | interval of a pair of roller in an appropriate range. Therefore, when the handle is tilted with respect to the plane including the pair of axes, the opening / closing regulating means can be further provided so that the above-mentioned action can be surely experienced, and as a result, a better cosmetic effect can be obtained. I can expect.

  In addition, the roller can have a substantially spherical shape. In this case, since the pressing force by the roller is easily concentrated on the portion sandwiched between the pair of rollers, the pressing force that can be experienced can be sufficiently increased, and a more excellent cosmetic effect can be expected. In this case, the operation of rotating the pair of rollers against the skin can be performed more smoothly, and the ease of handling of the beauty device can be further improved.

  Note that the substantially spherical shape described above includes a true sphere and a shape obtained by distorting the true sphere to such an extent that it is recognized as a sphere as a general sense such as a spheroid or teardrop shape. In addition, the roller may have a surface constituted by a smooth curved surface, for example, a polyhedron having a surface constituted by a large number of triangles, quadrangles and the like. When the roller is a polyhedron, the roller surface can be prevented from slipping against the skin as compared with a roller having a surface composed of a smooth curved surface, and a more excellent cosmetic effect can be expected.

  Moreover, the said handle | steering-wheel has a solar cell panel, and it may be comprised so that an electric current can be sent through the human body skin which contacts the said roller with the electromotive force of this solar cell panel. In this case, the skin cells are activated by the current flowing in the human skin, and there is a possibility that effects such as improvement of lymph flow, blood circulation, and improvement of metabolism may be exhibited. As a result, a better cosmetic effect can be expected by using the cosmetic device.

Another aspect of the present invention includes a handle including a pair of sub-handle portions and a connecting portion that connects the pair of sub-handle portions so as to be openable and closable.
Shaft portions respectively supported by the pair of sub handle portions;
A roller disposed on the shaft and supported rotatably about the axis of the shaft;
An urging member that generates an urging force for returning the relative positional relationship of the pair of sub-handle portions to the initial state,
The connecting portion has a rotation fulcrum,
The pair of sub handle portions are configured to rotate around the rotation fulcrum and open and close, and the pair of sub handle portions twist when rotating about the rotation fulcrum. It is in a cosmetics device which has a twist prevention member which prevents this.
According to the cosmetic device, since the twist preventing member prevents the pair of sub handle portions from being deformed to be twisted, the inclination angle of the axis of the shaft portion supported by the pair of sub handle portions is maintained. As a result, the skin surface can be sufficiently picked up by the pair of rollers, and a reduction in the beauty effect is prevented. As the torsion preventing member, various embodiments can be used as long as they have high rigidity.

A part of the upper surface and a part of the outer peripheral surface are covered. A nut 347 is attached to the handle shaft 340 via two washers 345 and a spring washer 346. The spring cover part 342c covers a part of the upper surface and a part of the outer peripheral surface of the winding part 510 of the spring member 51, thereby preventing the spring member 51 from coming off. Note that the spring washer 346 is located between the two washers 345. The spring washer 346 absorbs errors in the axial direction of the handle shaft 340 and suppresses rattling. Further, the collars 342 to 343 and the washer 345 reduce the friction generated in the handle shaft 340 and the like due to the rotation of the pair of sub handle portions 33a and 33b, thereby preventing the occurrence of looseness.

  Then, as shown in FIGS. 7A and 7B, the pair of sub handle portions 33a and 33b connected by the connecting portion 34 as described above rotate around the handle shaft 340 as a rotation fulcrum. It is configured to be able to open and close by moving. The spring member 51 applies a biasing force that biases the pair of sub handle portions 33a and 33b in the closing direction to the pair of sub handle portions 33a and 33b. Thus, the user presses the pair of rollers 4 at the tips of the pair of sub handle portions 33a and 33b against the skin surface, so that the pair of sub handle portions 33a and 33b opens against the urging force of the spring member 51. It is configured to rotate in the direction.

  Then, as shown in FIG. 8, in a state where the pair of sub handle portions 33a and 33b are connected by the connecting portion 34, the restriction pin 52 press-fitted into the press-fitting hole 383 of the core member 333 of the second sub handle portion 33b is The first sub handle 33a is located in the notch 385. Similarly, as shown in FIG. 9, the regulation pin 52 press-fitted into the press-fitting hole 383 of the core member 333 of the first sub handle part 33a is located in the notch part 385 of the second sub handle part 33b. .

  As shown in FIGS. 5 and 6, the connecting portion 34 is covered with a cylindrical connecting portion cover 35. The connecting portion cover 35 is made of an elastomer. In the initial state, the cover main body 351 located between the rear end portions of the pair of sub handle portions 33a and 33b and exposed, and the cover main body portion 351 toward the rear end portions of the pair of sub handle portions 33a and 33b. 7 and a pair of cover extending portions 352 located inside the rear end portions of the pair of sub handle portions 33a and 33b in the initial state shown in FIG. 7A. End portions in the extending direction of the pair of cover extending portions 352 are open, and in the state assembled to the pair of sub handle portions 33a and 33b, the in-cylinder space 353 of the connecting portion cover 35 is a pair of sub handle portions. It communicates with the space inside 33a, 33b.

  As shown in FIG. 6, a cylindrical inner rib 356 that is fitted inside the cylindrical portion 342 a of the upper collar 342 is erected on the inner side surface of the cover main body portion 351. The connecting portion cover 35 is fixed to the connecting portion 34 by fitting the inner rib 356 into the cylindrical portion 342a. Thereby, it is suppressed that the cover main-body part 351 moves with opening / closing operation | movement of a pair of sub handle part 33a, 33b. Further, as shown in FIG. 7A, a cover rear end portion 354 that is an end portion in the rear direction of the cover main body portion 351 is formed in a V shape. Accordingly, as the pair of sub handle portions 33a and 33b open and close in the opening direction from the initial state shown in FIG. 7A, the pair of sub handle portions 33a and 33b rotate about the handle shaft 340 as a fulcrum. As shown in FIG. 7B, the interval P between the rearmost portions of the regions facing each other at the rear end portions of the pair of sub handle portions 33a and 33b becomes narrower. Since the rear end portion 354 of the cover is V-shaped, the rear end portion 354 of the cover is compressed following the decrease in the distance P between the rear ends of the rear end portions of the pair of sub handle portions 33a and 33b. It is easily deformed. On the other hand, the distance Q between the front end portions of the regions facing each other at the rear end portions of the pair of sub handle portions 33a and 33b is from the initial state shown in FIG. 7A from the initial state of the pair of sub handle portions 33a and 33b. As it opens, it becomes wider as shown in FIG. Accordingly, the rear end portions of the pair of sub handle portions 33a and 33b are separated from the cover main body portion 351, but the pair of cover extending portions 352 extending from the cover main body portion 351 are connected to the cover main body portion 351. It will be exposed between the rear end portions of the pair of sub handle portions 33a and 33b. Therefore, it is possible to prevent the inside from being seen between the cover main body portion 351 and the pair of sub handle portions 33a and 33b.

  Moreover, as shown in FIG. 2, the solar cell part 6 is provided in a pair of sub handle part 33a, 33b. As shown in FIGS. 5 and 10, the solar cell unit 6 includes a lens 61, a solar cell panel 62, a substrate 63, a first connection terminal 64, a second connection terminal 65, and an energizing screw 66. A pair of terminals 62 a is connected to the solar cell panel 62 and disposed on the upper surface of the substrate 63. The pair of terminals 62 a are located on a pair of bosses 63 a having through holes provided in the substrate 63. And the lens 61 is attached to the board | substrate 63 with the screw 61a so that the whole region of the solar cell panel 62 may be covered. A sealing member 63 b is provided between the lens 61 and the substrate 63 along the outer edge of the substrate 63. Thereby, the water tightness of the space between the lens 61 and the board | substrate 63 is maintained, and the solar cell panel 62 is waterproofed from the outside. The solar cell unit 6 having such a configuration forms a single unit as shown in FIG. As shown in FIG. 5, a penetrating portion 610 is formed in the handle upper portion 332. The solar cell portion 6 is attached to the inner side surface of the handle upper portion 332 with a screw 67 so that the lens 61 is exposed from the penetrating portion 610.

  As shown in FIGS. 10 and 11, a first connection member 64 and a second connection member 65 are provided on the lower surface of the substrate 63. As shown in FIG. 5, the first connection member 64 and the second connection member 65 are formed with through holes 64 a and 65 a through which conductive conductive screws 66 are inserted. The first connecting member 64 and the second connecting member 65 are fixed to the lower surface of the substrate 63 by screwing the energizing screws 66 inserted through the through holes 64 a and 65 a into the pair of bosses 63 a of the substrate 63. Furthermore, as shown in FIG. 10, the tips of the energizing screws 66 screwed into the pair of bosses 63 a are in contact with the terminals 62 a of the solar cell panel 62. Thereby, the first connection member 64 and the second connection member 65 are electrically connected to the terminal 62 a of the solar cell panel 62 via the energizing screw 66.

  As shown in FIGS. 10 and 11, the first connection member 64 has a first connection portion 64 b that extends toward the core member 333 and contacts the core member 333. On the other hand, the second connection member 65 has a second connection portion 65 b extending so as to contact the inner side surface of the handle cover portion 334. Accordingly, the solar cell panel 62 is electrically connected to the handle cover portion 334 and the core member 33 via the first connection member 64 and the second connection member 65. Since the core member 33 is connected to the roller 4 so as to be energized, a closed circuit is formed by the user holding the handle 3 and bringing the roller 4 into contact with the skin surface. Thereby, an electric current can be sent through a human body by the electromotive force of the solar cell panel 62.

  Next, the usage mode of the cosmetic device 1 of this example will be described. When using the cosmetic device 1, the user first holds the grip portion 32 so that light enters the solar cell portion 6 while the handle cover portion 334 of the pair of sub handle portions 33 a and 33 b is in contact with the palm. To do. Then, as shown in FIG. 3, the pair of rollers 4 is pressed against the skin surface 8 so that the grip portion 32 is along the skin surface 8. By pressing the roller 4 against the skin surface 8 in this way, the plane P including the pair of axes A is inclined with respect to the skin surface 8.

  From the state in which the pair of rollers 4 is in contact with the skin surface 8, the force to press the pair of rollers 4 against the skin surface 8 is further increased, so that the spring member 51 is attached as shown in FIG. The handle 3 opens in the direction of the arrow 102 against the force, and the distance d between the pair of rollers 4 can be increased as indicated by the arrow 100 in FIG. The pair of shafts 2 in the cosmetic device 1 of the present example, as the distance d between the pair of rollers 4 is changed from the initial state and the initial state, as it goes from the base on the handle 3 side toward the distal end side. It is comprised so that the expansion state where the space | interval of a pair of axis line A expanded may be maintained. That is, the cosmetic device 1 of this example is configured to always be in an expanded state.

  When the pair of sub handle portions 33a and 33b are opened from the initial state, the core material 333 of the first sub handle portion 33a rotates in the direction of the arrow 102a with the handle shaft 340 as a fulcrum as shown in FIGS. While moving, the core member 333 of the second sub handle portion 33b rotates in the direction of the arrow 102b with the handle shaft 340 as a fulcrum. Along with this, the restriction pin 52 moves in the backward direction. When the two core members 333 are rotated by a predetermined amount in the opening direction, the restriction pin 52 comes into contact with the rear end surface 385a of the notch 385, and the two core members 333 are restricted from rotating further in the opening direction. The In the initial state, the core member 333 of the first sub handle portion 33a is biased by the spring member 51 in the direction of the arrow 102b, and the core member 333 of the second sub handle portion 33b is biased in the direction of the arrow 102a. It is energized. As a result, the pair of sub-handle portions 33a and 33b are urged in the closing direction, and the regulation pin 52 comes into contact with the front end surface 385b of the notch portion 385 so that both core members 333 are rotated in the closing direction. To be regulated.

  The regulation pin 52 and the notch portion 385 in the cosmetic device 1 of this example can change the distance d between the pair of rollers 4 within a range of 1 to 50 mm when the pair of sub handle portions 33a and 33b are opened and closed. Designed to. And since the core material 333 which consists of metal board | plate materials is provided, even if the force which presses a pair of roller 4 against the skin surface 8 is enlarged in the state where the space | interval d of a pair of roller 4 became the maximum, a pair of The sub-handle portions 33a and 33b are not easily elastically deformed, and the distance d between the pair of rollers 4 is configured not to be further increased.

  And in the state which made the pair of roller 4 contact | abut to the skin surface 8, by moving the cosmetic device 1 to the direction which goes to the handle 3 side from the roller 4 side, a cosmetic effect is shown as shown in FIG.3 and FIG.4. The part to be obtained is caught between the pair of rollers 4, and the skin surface 8 is deformed so as to be picked up by the pair of rollers 4.

  At this time, the pressing force applied to the portion sandwiched between the pair of rollers 4 can be increased by moving the cosmetic device 1 and applying a force in the direction of closing the pair of sub handle portions 33a and 33b. it can.

  Further, while the roller 4 is in contact with the skin surface 8 and the handle cover portion 334 of the handle 3 is in contact with the palm, a closed circuit including the solar cell panel 6, the roller 4, the handle cover portion 334, and the human body is present. It is formed. Therefore, an electric current can be made to flow to the human skin which contacts the roller 4 by the electromotive force of the solar cell panel 62.

  Next, the function and effect of this example will be described.

  According to the cosmetic device 1 of the present embodiment, the pair of sub handle portions 33a and 33b are connected by the connecting portion 34 so that the sub handle portions 33a and 33b can be rotated by the handle shaft 340 which is one rotation fulcrum and can be opened and closed. Thereby, compared with the case where a pair of sub handle part 33a, 33b rotates by an individual rotation fulcrum, adjustment of the relative force adjustment in a pair of sub handle part 33a, 33b becomes easy. As a result, it becomes easier to pick up the skin surface 8, and the beauty effect is improved. Further, the urging force for returning the pair of sub handle portions 33a and 33b to the initial state does not have to be considered because the pair of sub handle portions 33a and 33b rotate at individual rotation fulcrums. A reduction in the design freedom of the spring member 51 as the urging member 5 is prevented.

  The pair of sub handle portions 33a and 33b support the shaft portion 2 of the pair of rollers 4 and are connected to each other so as to be opened and closed. Accordingly, the user can push the pair of sub handle portions 33a and 33b by pressing the pair of rollers 4 against a portion where the cosmetic effect is desired to be obtained, and the pair of rollers 4 according to the shape of the part to be used. The distance d can be adjusted as appropriate. As a result, the cosmetic device 1 of this example can be suitably used from a relatively large undulating portion such as a face or an arm to a relatively small undulating portion such as an abdomen.

  Further, in the cosmetic device 1 of this example, the user can easily adjust the pressing force applied to the portion where the cosmetic effect is desired by adjusting the degree of opening and closing of the pair of sub handle portions 33a and 33b. Therefore, the cosmetic device 1 is easy to handle. In addition, the pressing force of the pair of rollers 4 can be expected to promote the blood circulation of the pressed portion, activate the metabolism, etc., and thus can expect excellent cosmetic effects such as beautifying the skin. .

  Further, the cosmetic device 1 of this example includes a spring member 51 as a biasing member that generates a biasing force for returning the relative positional relationship between the pair of sub handle portions 33a and 33b to the initial state. Thus, in a state where the pair of sub handle portions 33a and 33b are rotated in the opening direction and the distance d between the pair of rollers 4 is widened, the urging force by the urging member acts on each roller 4, and the pair of rollers 4 are biased in a direction approaching each other. Therefore, a moderately large pressing force can be applied to the portion sandwiched between the pair of rollers 4. As a result, a better beauty effect can be expected.

  Further, in the cosmetic device 1 of this example, the pair of sub handle portions 33a and 33b are prevented from being twisted when the pair of sub handle portions 33a and 33b are twisted when the handle shaft 340 is rotated as a pivot. It has a core material 333 as a member. When the pair of sub-handle portions 33a and 33b are deformed so as to be twisted when the pair of rollers 4 are pressed against the skin surface 8, the angle θ of the shaft portion 2 supported by the pair of sub-handle portions 33a and 33b changes. Thus, the skin surface 8 cannot be sufficiently picked up by the pair of rollers 4, and the beauty effect may be reduced. However, as described above, by having the core member 333 as a twist preventing member, the pair of sub handle portions 33a and 33b are prevented from being deformed so as to be twisted, so that the pair of sub handle portions 33a and 33b are supported. The angle θ of the shaft portion 2 to be maintained is maintained, and the reduction of the beauty effect is prevented.

  Further, in the cosmetic device 1 of the present example, the pair of sub handle portions 33a and 33b includes a handle lower side portion 331, a handle upper side portion 332, and outer handle forming portions that form the outer surfaces of the pair of sub handle portions 33a and 33b. A handle cover portion 334 is provided. The twist preventing member is formed of a core material 333 that is disposed inside the outer surface forming portion and has higher rigidity than the outer surface forming portion. Accordingly, the core material 333 as a twist preventing member can prevent the pair of sub handle portions 33a and 33b from being twisted to prevent a reduction in the beauty effect, and the handle lower side portion 331 as the outer surface forming portion and the handle. The upper portion 332 and the handle cover portion 334 can increase the degree of freedom of design such as making the shape easy for a user to hold or making the shape exhibit high designability.

  Further, in the cosmetic device 1 of this example, a stainless steel plate is used as the core material 333. Thereby, sufficient rigidity can be obtained, and the pair of sub handle portions 33a and 33b is prevented from being twisted to prevent a reduction in beauty effect.

  In the cosmetic device 1 of the present example, the core member 33 is provided over half or more of the longitudinal length of the pair of sub handle portions 33a and 33b in the longitudinal direction of the pair of sub handle portions 33a and 33b. . Thereby, the rigidity of the pair of sub handle portions 33a and 33b is increased, and the twist of the pair of sub handle portions 33a and 33b can be further prevented.

  Furthermore, in the cosmetic device 1 of this example, the core material 333 is provided over the entire pair of sub handle portions 33a and 33b in the longitudinal direction of the pair of sub handle portions 33a and 33b. Thereby, the rigidity of the pair of sub handle portions 33a and 33b is further increased, and the twist of the pair of sub handle portions 33a and 33b can be further prevented.

  Further, in the cosmetic device 1 of this example, the pair of core members 333 each have a through hole 381 at the end portion 38, and the pivot point of the connecting portion 34 is the same as the through hole 381 of the pair of core members 333. The handle shaft 340 is inserted through the through-hole 381 so as to overlap the axis L1. Thereby, a pair of sub handle part 33a, 33b can be rotated by one rotation fulcrum by simple structure.

  Further, in the cosmetic device 1 of the present example, the core member 333 has a through hole 371 as a shaft support portion that supports the shaft portion 2 on the first end portion 37 opposite to the second end portion 38 provided with the through hole 381. Is provided. Thereby, the user can change the space | interval d of a pair of roller 4 by adjusting the opening / closing degree of a pair of sub handle part 33a, 33b. Therefore, it becomes easy for the user to sensuously understand the relationship between the magnitude of the opening / closing operation of the pair of sub handle portions 33a and 33b and the amount of change in the distance d between the pair of rollers 4. Further, by adjusting the degree of opening and closing of the pair of sub handle portions 33a and 33b, it is possible to easily adjust the pressing force applied to the portion where the cosmetic effect is desired. As a result, the ease of handling of the beauty device 1 can be further improved, and a better beauty effect can be expected.

  Further, in the state in which the distance d between the pair of rollers 4 is widened, the cosmetic device 1 is biased in a direction in which the biasing force by the biasing member 5 acts on each roller 4 and the pair of rollers 4 approaches each other. . Therefore, effects such as promoting blood circulation in the portion pressed by the pair of rollers 4 and activating metabolism can be expected, and as a result, beauty effects such as beautifying the skin can be expected.

  Moreover, the beauty device 1 has a restriction pin 52 as an opening / closing restriction part and a notch 385. Therefore, the cosmetic device 1 can reliably prevent the interval d between the pair of rollers 4 from being excessively wide and can reliably prevent the cosmetic device 1 from being damaged.

  In addition, the pair of shaft portions 2 are always arranged so as to be in an expanded state in which the distance between the pair of axis lines A increases from the base portion on the handle 3 side toward the distal end side. That is, the cosmetic device 1 is easier to handle for the user by realizing the expanded state in the initial state. Further, by realizing the expanded state in a state where the distance d between the pair of rollers 4 is changed from the initial state, it is possible to appropriately increase the pressing force experienced in the portion sandwiched between the pair of rollers 4. , You can expect a better beauty effect.

  The handle 3 is inclined with respect to the plane P including the pair of axes A. Furthermore, in this example, the regulation pin 52 and the notch portion 385 can change the distance d between the pair of rollers 4 within a range of 1 to 50 mm when the pair of sub handle portions 33a and 33b are opened and closed. Designed. By maintaining the distance d between the pair of rollers 4 within an appropriate range, the above-described effect of picking up the skin can be surely experienced. As a result, a better beauty effect can be expected.

  The roller 4 has a substantially spherical shape. Therefore, the pressing force by the roller 4 tends to concentrate, and the pressing force felt by the user tends to be sufficiently large. Moreover, the operation | movement rotated while pressing a pair of roller 4 against skin can be performed more smoothly, and the ease of handling of the beauty device 1 can be improved more.

  Further, the handle 3 has a solar cell portion 6 and is configured to allow a current to flow to the human skin contacting the roller 4 by the electromotive force of the solar cell panel 62. Therefore, the use of the cosmetic device 1 can be expected to have a better beauty effect.

  Moreover, the solar cell part 6 forms a single unit, and the solar cell panel 62 is sealed from the outside by a seal part 63b to be waterproofed. Thereby, since the waterproof property of the solar cell panel 62 can be secured without securing the waterproof property of the entire sub handle portions 33a and 33b provided with the solar cell portion 6, the waterproof property of the entire sub handle portions 33a and 33b is ensured. This eliminates the need for a sealing member for reducing the number of parts. Furthermore, since the solar cell unit 6 forms a single unit, when an external force is applied to the sub handle portions 33a and 33b, the handle lower side portion 331, the handle upper side portion 332, and the handle cover 334 are bent. However, the solar cell unit 6 itself is not easily deformed. Therefore, even in such a case, it is easy to maintain the waterproof property of the solar cell panel 62.

  In this example, the handle lower side portion 331, the handle upper side portion 332, and the handle cover 334 as the outer surface forming portions of the pair of sub handle portions 33a and 33b are arranged in the front-rear direction of the outer surface of the pair of sub handle portions 33a and 33b. The cross section is substantially elliptical. Thereby, the outer surface forming portion is also structurally improved in rigidity. As a result, the rigidity of the entire pair of sub handle portions 33a and 33b is improved together with the core material 333, and twisting of the pair of sub handle portions 33a and 33b is further prevented.

  The pair of sub handle portions 33a and 33b may be formed as a single piece made of metal. In this case, since the pair of sub handle portions 33a and 33b themselves also function as a core material, the rigidity of the pair of sub handle portions 33a and 33b can be further increased. As a result, twisting of the pair of sub handle portions 33a and 33b can be further prevented.

  If the rigidity of the pair of sub handle portions 33a and 33b is excessively low, the sub handle portions 33a and 33b may bend when the pair of rollers 4 tries to press a portion where a cosmetic effect is desired. Therefore, in some cases, even if the opening / closing operation is performed in the direction of closing the pair of sub handle portions 33a and 33b, the distance d between the pair of rollers 4 is not sufficiently narrowed, and the pressing force applied to the portion where a cosmetic effect is desired is sufficiently obtained. You may not be able to experience it. On the other hand, the cosmetic device 1 of this example can avoid such a problem by having the above-described configuration, and can sufficiently increase the pressing force applied to the portion where the cosmetic effect is desired to be obtained by the opening / closing operation of the handle 3. As a result, the cosmetic device 1 can sufficiently increase the pressing force that can be experienced, and can expect a better cosmetic effect.

  As described above, the beauty machine 1 can be suitably used for each part of the body and can be expected to have an excellent beauty effect.

(Evaluation test)
About the cosmetic device 1 of the said Example, the evaluation test by a sensory test was done. The cosmetic device 1 of the above example was prepared as a test example, and the conventional cosmetic device 900 shown in FIG. 12 was prepared as a comparative example. As shown in FIG. 12, in the conventional cosmetic device 900, the pair of sub handle portions 933 are made of ABS resin and do not have the core material 333. Although not shown, a pair of rollers having the same configuration as the roller 4 of the cosmetic device 1 of the present embodiment is provided at the front ends of the pair of sub handle portions 933.

  A connection plate 953 and a leaf spring 951 are provided on the connection portion 934 of the pair of sub handle portions 933. The connection plate 953 is substantially U-shaped in plan view, and has a pair of through holes 954 and a pair of restriction grooves 956. A boss 955 that protrudes from the inner side surface of the sub handle portion 933 is inserted into the pair of through holes 954. Thereby, a pair of sub handle part 933 is connected. In addition, in the pair of restriction grooves 956, restriction pins 952 that protrude from the inner side surface of the sub handle portion 933 are located. In the cosmetic device 900 of the comparative example, the pair of sub handle portions 933 can be individually rotated and opened / closed using the boss 955 inserted through the pair of through holes 954 as a rotation fulcrum. The range in which the pair of sub handle portions 933 can be opened and closed is a range in which the regulation pins 952 positioned in the pair of regulation grooves 956 can move in the regulation grooves 956. In the cosmetic device 900 of the comparative example, the regulation pin 952 and the regulation groove 956 are set so that the distance between the rollers is in the range of 1 to 50 mm as in the cosmetic device 1 of the present embodiment.

The evaluation method is as follows. First, a total of 31 people including 15 men and 16 women in their 20s to 50s were taken as subjects.
As an evaluation test 1, a practitioner who is blindfolded on the subject performs a calf operation using the cosmetic device 1 of the above test example and the cosmetic device 900 of the comparative example, and evaluates the subject's sensation. did. The practitioner performed the treatment with the same strength and speed in both the cosmetic device 1 of the test example and the cosmetic device 900 of the comparative example.
In addition, as an evaluation test 2, the subject himself applied to his calf using the cosmetic device 1 of the test example and the cosmetic device 900 of the comparative example, and evaluated the bodily sensation.
The evaluation of the bodily sensation was made by selecting the person who wanted to use after performing treatment with both cosmetic instruments.
Table 1 below shows the results of evaluation tests 1 and 2.

  As shown in Table 1, in the evaluation test 1, the ratio of using the cosmetic device 1 of the test example was 71%, and 22 out of 31 subjects selected the cosmetic device 1 of the test example. On the other hand, in the evaluation test 1, the ratio of using the cosmetic device 900 of the comparative example was 23%, and 7 out of 31 subjects selected the cosmetic device 900 of the comparative example. In the evaluation test 2, the ratio of using the cosmetic device 1 of the test example is 84%, and 26 out of 31 subjects selected the cosmetic device 1 of the test example. On the other hand, in the evaluation test 2, the ratio of using the cosmetic device 900 of the comparative example is 10%, and 3 out of 31 subjects selected the cosmetic device 900 of the comparative example.

  As described above, in both of the evaluation tests 1 and 2, the ratio of using the cosmetic device 1 of the test example was higher than that of the cosmetic device 900 of the comparative example. This is because the cosmetic device 900 of the comparative example does not have the core material 333, so that when the roller is pressed against the skin surface, the sub handle portion 933 is twisted, and the distance between the rollers is increased, thereby picking up the skin surface. This is presumed to be due to the fact that this was not done sufficiently.

  Further, in the cosmetic device 900 of the comparative example, since the pair of sub handle portions 933 rotate at individual rotation fulcrums, adjustment of the force applied to the pair of sub handle portions 933 to maintain the optimum distance between the rollers is adjusted. However, in the cosmetic device 1 of the test example, since the pair of sub handle portions 33a and 33b are rotated by the handle shaft 340 which is one rotation fulcrum, it is assumed that the adjustment of the force is easy. Is done.

  As described above, it can be confirmed from the evaluation tests 1 and 2 that the cosmetic device 1 of Example 1 has an improved feeling compared to the cosmetic device 900 of the comparative example.
