One embodiment of the present invention is a cosmetic device characterized in that it has:

a handle having a pair of shafts;

rollers, which are respectively provided on the shaft portion while being rotatably supported around the axis of the shaft portion, and configured to be able to change the intervals therebetween; and

The urging member generates an urging force for restoring the gap between the pair of rollers to a natural state.

Invention effect

The said beauty device has the said pair of rollers which are respectively provided in the said shaft part, and are rotatably supported centering on the axis|shaft of this shaft part. In addition, the above-mentioned pair of rollers is configured such that the interval between them can be changed. It further has an urging member for generating an urging force for restoring the distance between the pair of rollers to a natural state. That is, the above-mentioned pair of rollers are configured so that the distance between them is variable, and on the other hand, when the distance between them changes from the natural state, they receive an applied force that tries to restore the distance to the natural state.

Therefore, by pressing the pair of rollers on the part where the beauty effect is to be obtained, the distance between the pair of rollers can be enlarged according to the shape of the part where the beauty effect is to be obtained against the above-mentioned applied force. Adjust the distance between the above pair of rollers accordingly. As a result, the above-mentioned cosmetics device can be used suitably from parts with relatively large ups and downs, such as the face and arms, to parts with relatively small ups and downs, such as the abdomen.

Moreover, the said beauty device acts on each of the said rollers by the said biasing force by the said biasing member in the state which the space|interval of the said pair of rollers widened, and it biases in the direction which makes the said pair of rollers approach each other. Therefore, a moderately large pressing force can be applied to the portion sandwiched between the pair of rollers. As a result, effects such as promoting blood circulation and activating metabolism of the pressed part of the skin can be expected, and further cosmetic effects such as beautifying the skin can be expected.

As mentioned above, the said cosmetics device can be used suitably for each part of a body, and the outstanding cosmetic effect can be expected.

detailed description

In the above-mentioned cosmetics device, the above-mentioned natural state refers to a state in which the above-mentioned cosmetics device is not used and a part to obtain a cosmetic effect is not sandwiched between a pair of rollers.

The said cosmetics device may have the opening and closing restriction material which restrict|limits the upper limit of the space|interval of said pair of rollers. The said cosmetics device can prevent reliably that the space|interval of a pair of roller becomes too wide by providing the said opening and closing regulator. As a result, the breakage of the said cosmetics device can be prevented reliably.

Preferably, the distance between the pair of rollers is restricted to 50 mm or less, more preferably 35 mm or less, and further preferably 20 mm or less by the opening and closing restricting member. On the other hand, although the lower limit of the distance between the rollers may not be limited, if the pressing force felt by the portion sandwiched between the pair of rollers is too large, it may be limited by the opening and closing limiter or other members.

As a configuration capable of changing the distance between the pair of rollers, for example, there is a configuration in which the shaft portion is attached to the handle in an openable and closable state. In this case, the distance between the pair of rollers can be changed according to the opening and closing operation of the shaft portion. In addition, in the case of adopting the above configuration, as the opening and closing restricting member, for example, a member that restricts the upper limit of the opening and closing range of the shaft portion may be provided. That is, by providing the member at a position in contact with the shaft in the open state compared to the natural state, the upper limit of the opening and closing range of the shaft can be restricted according to the position of the member. As a result, the upper limit of the distance between the pair of rollers can be limited.

In addition, the above-mentioned handle has a pair of sub-handle parts respectively supporting the above-mentioned shaft part and a linking part which connects the pair of sub-handle parts so as to be openable and closable. And the connecting part that can expand and contract. In this case, the durability of the connecting portion against repeated opening and closing operations can be improved. As a result, the breakage of a connection part can be suppressed, and the said cosmetics device can be used continuously for a longer period of time.

The connection member may have a stretchable structure such as a bellows structure, or may be made of an easily stretchable material. In either case, if the said connection member can expand and contract with opening and closing of the said sub-handle part, damage of a connection part can be suppressed, and the durability of a beauty device can be improved.

When an easily stretchable material is used for the connection member, it is preferable that the connection member is formed of an elastic body. As the elastic body used for the above-mentioned connecting member, a material having rubber elasticity such as natural rubber or synthetic rubber can be used.

Since the connecting member made of an elastic body easily expands and contracts with the opening and closing operation of the sub-handle portion, the durability of the connection portion against repeated opening and closing operations can be further improved. As a result, the durability of a beauty device can be further improved.

In addition, the connecting member formed of the elastic body can generate an urging force for returning the position of the sub-handle parts to the natural state when the pair of sub-handle parts are opened and closed. For example, in a state in which the pair of sub-handles is opened and the distance between the pair of rollers is widened, the biasing force from the connecting member acts on each roller to bias the pair of rollers toward each other. Therefore, a moderately large pressing force can be applied to the portion sandwiched between the pair of rollers. As a result, a more excellent cosmetic effect can be expected.

In addition, the pair of shaft portions and the coupling portion may be provided at opposite ends of the sub-handle portion. In this case, the user can change the distance between the pair of rollers by adjusting the degree of opening and closing of the sub-handle portion. Therefore, it is easy for the user to understand the relationship between the magnitude of the opening and closing movement of the handle and the amount of change in the distance between the pair of rollers. In addition, by adjusting the degree of opening and closing of the above-mentioned sub-handle portion, it is possible to easily adjust the pressing force applied to the portion where the cosmetic effect is to be obtained. As a result, the ease of handling of a cosmetics device can be further improved, and a more excellent cosmetics effect can be expected.

When the handle has a sub-handle portion and the connection portion, for example, a member that restricts an upper limit of an opening and closing range of the sub-handle portion may be provided as the opening/closing restricting member. That is, by providing the above-mentioned member at a position in contact with the sub-handle part in the opened state compared to the natural state, the upper limit of the opening and closing range of the sub-handle part can be restricted according to the position of the above-mentioned member. As a result, the upper limit of the distance between the pair of rollers can be limited. Furthermore, the pair of child handle parts can be prevented from being excessively opened by the opening/closing restricting member. Thereby, damage|damage of the said connection member can be prevented, and the durability of the said cosmetics device can be improved more.

When the said cosmetics device has the said structure, you may comprise so that a sub-handle part itself may function as the said opening and closing regulator. As said structure, for example, there exists a structure which mutually abuts with a part of the sub-handle part in the open state rather than a natural state. The sub-handles thus constituted limit the opening and closing range with the mutual abutting state as the upper limit. As a result, the upper limit of the distance between the pair of rollers can be limited.

Moreover, when the said cosmetics device has the said structure, the said opening and closing regulator may be provided in the said connection part. In this case, since the said link part and the said opening and closing regulator related to the opening and closing operation|movement of the said sub-handle part are collectively arrange|positioned in one place, the degree of freedom of design of the said cosmetics device can be improved further. Moreover, the ease of operability of a cosmetics device can be further improved by collecting the said connection part and the said opening and closing regulator in one place.

In addition, the connecting portion may have a reinforcing member having a bridge portion spanning between the pair of sub-handle portions and configured to suppress displacement of the pair of sub-handle portions in directions other than the opening and closing direction. In this case, the above-mentioned cosmetics device can suppress displacement of the pair of child handle parts in directions other than the opening and closing direction by actively providing the reinforcing member having the above-mentioned function on the connection part. Accordingly, forces in directions other than the opening and closing directions, such as torsional forces and bending forces, which are applied to the connecting member, can be reduced. As a result, the breakage of a connection member can be prevented, and the durability of the said cosmetics device can be improved more.

The shape and material of the reinforcing member may take various forms as long as the rigidity of the bridge portion in the torsional direction is sufficiently high. For example, by using a metal plate as the reinforcing member, the rigidity of the bridge portion can be sufficiently increased. In addition, the rigidity of the bridge portion can be further increased by using a relatively strong metal plate such as a stainless steel plate, or by increasing the thickness of the plate. Usually, by using a stainless steel plate as the reinforcing member, sufficient rigidity can be obtained, and breakage of the connecting member can be suppressed.

From the viewpoint of further improving the durability of the cosmetics device, a reinforcing member having a bridge portion that positively improves rigidity in directions other than the opening and closing direction of the sub-handle portion may be used. For example, by making the cross-sectional shape of the bridge portion in the longitudinal direction (the direction in which the pair of sub-handle portions are arranged) substantially L-shaped or approximately rectangular cylindrical, rigidity in the torsional direction and the bending direction can be positively improved.

The reinforcing member may have an arm portion extending from the bridge portion along the length direction of each sub-handle portion. In this case, due to the presence of the arm portion, the sub-handle portion can be effectively suppressed from being displaced in a direction in which a torsional force is applied to the connection member. As a result, the breakage of a connection member can be suppressed, and the durability of a cosmetics device can be improved more.

In addition, each of the above-mentioned sub-handle parts has more than two engaging parts arranged at intervals in the length direction, and at the same time, the plurality of engaging parts can be engaged with a plurality of engaged parts provided on the above-mentioned reinforcing member. combine. In this case, since each sub-handle part is engaged with the reinforcing member at two or more places in the longitudinal direction, displacement of the sub-handle part in a direction in which a torsional force is applied to the connection part can be effectively suppressed. As a result, the breakage of a connection part can be suppressed, and the durability of a beauty device can be improved more.

In the above case, preferably, the reinforcement member is configured such that the sub-handle portion can relatively move in an opening and closing direction with respect to the reinforcement member in at least one engaged portion. In this case, since the reinforcing member does not hinder the opening and closing operation of the sub-handle section, the opening and closing operation of the sub-handle section can be easily performed. As a result, it becomes easier to handle the beauty device.

Moreover, it is preferable that the said connection member has a cylindrical shape, and at least a part of the said connection part is covered with the said connection member. That is, it is preferable that at least a part of the opening/closing regulating member, the reinforcing member, the urging member, and the like is arranged in the cylinder of the connecting member. In this case, since the opening and closing regulator and the reinforcing member are protected by the above-mentioned connecting member, damage to them can be suppressed. As a result, the durability of a beauty device can be further improved.

The pair of shafts may be disposed in a developed state in which the distance between the pair of axis lines increases from the handle-side base toward the front end in the natural state. In this case, when the said cosmetics device is pressed against skin, the space|interval of said pair of rollers can be enlarged easily. As a result, the said cosmetics device is easy to handle for a user.

In addition, in the above-mentioned natural state, the above-mentioned pair of rollers can be separated from each other. In this case, when the above-mentioned pair of rollers is pressed against the portion where the cosmetic effect is to be obtained, a state in which the portion is sandwiched between the above-mentioned rollers to some extent can be naturally realized. On the other hand, when the pair of rollers are in contact with each other in a natural state, in order to achieve a state where the part is sandwiched between the rollers, it is necessary to increase the distance between the pair of rollers against the applied force. Therefore, in the above-mentioned natural state, the cosmetic device in which the pair of rollers are separated from each other can more easily sandwich the part to obtain a cosmetic effect between the above-mentioned rollers, which is easier for the user to operate. Furthermore, when the pair of rollers are separated from each other in the natural state, the distance between the pair of rollers in the natural state can be appropriately set within a range of 1 to 50 mm.

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

In addition, preferably, the handle is inclined with respect to a plane including the pair of axes. In this case, by pressing the pair of rollers against the skin surface so that the handle is along the skin surface, a plane including the pair of axes is inclined relative to the skin surface. Then, by moving the above-mentioned cosmetics container while maintaining this state, the portion to be obtained with a cosmetic effect can be deformed in a pulling-up manner by a pair of rollers. As a result, more excellent cosmetic effects can be expected by using the said cosmetics device.

In addition, the skin-lifting effect described above varies depending on the distance between the pair of rollers, and the above-mentioned effect can be felt reliably by keeping the distance between the pair of rollers within an appropriate range. Therefore, when the handle is inclined with respect to the plane including the pair of axes, by further providing the opening/closing restrictor, the above-mentioned action can be reliably felt, and a more excellent cosmetic effect can be expected.

In addition, the above-mentioned roller may be formed in a substantially spherical shape. In this case, since the pressing force from the rollers tends to concentrate on the portion sandwiched between the pair of rollers, the perceived pressing force can be sufficiently increased, and a more excellent cosmetic effect can be expected. In addition, in this case, the operation of rotating the rollers while pressing the pair of rollers on the skin can be performed more smoothly, and the ease of handling of the beauty device can be further improved.

In addition, the above-mentioned substantially spherical shape includes a shape formed by distorting a true sphere to such an extent that it can generally be regarded as a sphere, such as a true sphere, a spheroid, or a teardrop shape. In addition, the above-mentioned roller may have a surface composed of a smooth curved surface, for example, may be a polyhedron having a surface composed of a plurality of triangles, quadrilaterals, or the like. When the above-mentioned roller is a polyhedron, compared with a roller having a surface composed of a smooth curved surface, slipping of the surface of the roller with respect to the skin can be suppressed, and a more excellent cosmetic effect can be expected.

In addition, in the above-mentioned urging member, for example, a spring member, rubber, or the like can be used. Among them, it is preferable to use a spring member made of metal as the biasing member. A spring member made of metal can easily increase the above-mentioned biasing force moderately. Therefore, by using the said cosmetics device, a more excellent cosmetic effect can be expected.

In addition, the handle may have a solar cell panel, and may be configured to allow current to flow through the human skin in contact with the roller by utilizing electromotive force of the solar cell panel. In this case, it is possible to exert the effects of activating skin cells, improving lymphatic flow, promoting blood circulation, improving metabolism, etc. by utilizing the electric current that flows through human skin. As a result, more excellent cosmetic effects can be expected by using the said cosmetics device.

Example

(Example 1)

The Example of the said cosmetics device is demonstrated using FIGS. 1-9. As shown in FIGS. 1 and 5 , the beauty device 1 has a handle 3 having a pair of shafts 2 , a pair of rollers 4 , and a spring member 51 as a biasing member 5 . A pair of rollers 4 are provided on the shaft portion 2, respectively, and are rotatably supported around an axis line A of the shaft portion 2 (see FIGS. 3 and 4 ). In addition, the pair of rollers 4 is configured to be able to change the distance d between them as shown in FIG. 4 . The spring member 51 is configured to generate an urging force for returning the distance d between the pair of rollers 4 to a natural state. Moreover, as shown in FIG. 8, the cosmetics device 1 has the control plate 71 and the control pin 72 which are the opening and closing control means which control the upper limit of the space|interval d of a pair of roller 4. As shown in FIG.

As shown in FIGS. 1 and 2 , the beauty device 1 has a handle 3 having a substantially U-shape. A pair of rollers 4 are arranged in line with each other on the bifurcated front end of the handle 3 . A pair of rollers 4 are rotatably supported by the handle 3 via a shaft portion 2 provided at the front end of the handle 3 . Moreover, as shown in FIG. 3, the cosmetics device 1 is curved so that it may show a substantially arc shape when viewed from the direction in which a pair of rollers 4 are arranged.

Hereinafter, the direction in which the pair of rollers 4 are arranged may be referred to as a "lateral direction", and the direction in which the rollers 4 and the handle 3 are arranged may be referred to as a "front-rear direction". In addition, the side of the roller 4 in the front-rear direction may be referred to as "front", and the side of the handle 3 may be referred to as "rear". In addition, the convex side may be called "upper side" and the concave side may be called "lower side" in the substantially arc shape when seeing the cosmetics device 1 from a side direction. These descriptions about directions are just for convenience, and have nothing to do with the actual directions when using the beauty device 1 .

As shown in FIGS. 1 to 4 , in the handle 3 , the shaft support portion 31 supporting the shaft portion 2 is bent obliquely downward relative to the longitudinal direction of the grip portion 32 further behind. In other words, in the plan view shown in FIG. 2 and the front view shown in FIG. 4 , the shaft support portion 31 of the handle 3 becomes wider outward in the lateral direction as it goes forward. In addition, although not shown for the sake of convenience, the shaft portions 2 supported by the shaft support portions 31 are extended outward together with the shaft support portions 31 so as to become wider toward the front. As a result, the pair of shafts 2 are arranged in a developed state in which the distance between the pair of axis lines A increases from the base on the handle 3 side toward the front end (front) in a natural state. In addition, the angle (theta) (refer FIG. 4) formed by a pair of axis lines A in the cosmetics device 1 of this example is 70 degrees. The angle θ formed by the pair of axes A can be suitably set within the range of 40° to 120°, more preferably within the range of 50° to 90°.

In addition, in the side view shown in FIG. 3 , the shaft support portion 31 of the handle 3 faces obliquely downward with respect to the longitudinal direction of the grip portion 32 . Furthermore, the shaft parts 2 respectively provided on the shaft support parts 31 extend obliquely downward together with the shaft support parts 31 (not shown). Therefore, the grip portion 32 of the handle 3 is inclined with respect to the plane P including the pair of axes A. As shown in FIG.

As shown in FIGS. 2 and 3 , the roller 4 supported by the handle 3 via the shaft portion 2 is a polyhedron composed of a plurality of triangles and has a substantially spherical shape. Between the handle 3 and the roller 4 , an unillustrated gasket is provided to prevent moisture and the like from entering between the handle 3 and the roller 4 . In addition, titanium plating is applied to the surface of the roller 4 to have electrical conductivity. The surface of the roller 4 is electrically connected to a solar battery panel 6 described later. In addition, the beauty device 1 of this example is comprised so that the distance d (refer FIG. 4) of a pair of roller 4 in a natural state may be 10 mm. In addition, the diameter of the roller 4 in this example on the cross section perpendicular to the axis A can be appropriately selected from the range of 15 to 60 mm.

In addition, as shown in FIG. 2 , FIG. 5 to FIG. 6 and FIG. 8 , a spring member 51 and an opening and closing restricting member are provided behind the handle 3 . The details of the spring member 51 and the opening/closing regulator will be described later.

As shown in FIG. 1 , FIG. 2 and FIG. 5 , the handle 3 has a pair of sub-handle parts 33 each supporting the shaft part 2 and a connecting part 34 that connects the pair of sub-handle parts 33 so as to be openable and closable. As shown in FIGS. 1 and 2 , the connecting portion 34 is disposed behind the handle 3 , that is, at an end portion opposite to the roller 4 . Furthermore, the sub-handle parts 33 are extended forward from the connection part 34, and are arrange|positioned mutually side by side. Thus, in the beauty device 1 of this example, a pair of shaft part 2 and the connection part 34 are provided in the end part of the mutually opposite side of the sub-handle part 33. As shown in FIG.

As shown in FIG. 2 , the sub-handle portion 33 is substantially rod-shaped, and has a substantially elliptical cross-section perpendicular to the front-rear direction to improve structural rigidity.

In addition, as shown in FIG. 5 , the sub-handle portion 33 has: a base portion 331 extending in the entire front-rear direction; a lower spring accommodating portion 332 and an upper spring accommodating portion 333 for accommodating the spring member 51; 333 of the shell portion 334 . The lower spring accommodating portion 332 , the upper spring accommodating portion 333 , and the case portion 334 are disposed on the rear half of the sub-handle portion 33 . In addition, as shown in FIGS. 5 and 7 , the lower spring receiving portion 332 , the upper spring receiving portion 333 , and the shell portion 334 are connected to the base portion 331 by screws 335 at both ends in the front-rear direction.

The base 331 is formed of an electrically insulating resin. In addition, as shown in FIGS. 2 and 5 , the base portion 331 has the solar cell panel 6 between the case portion 334 and the shaft support portion 31 of the handle 3 . The solar cell panel 6 is mounted with a spacer not shown so as to prevent intrusion of water or the like through a gap with the base 331 . Moreover, although not shown in figure, the solar cell panel 6, the roller 4, and the case part 334 provided in the same sub-handle part 33 are mutually electrically connected. Furthermore, as will be described later, the electromotive force of the solar battery panel 6 is used to allow current to flow through the human skin in contact with the roller 4 .

The upper spring housing portion 333 and the lower spring housing portion 332 are formed of electrically insulating resin. As shown in FIG. 6 , the upper spring housing portion 333 and the lower spring housing portion 332 are configured to form a spring housing space 35 for housing the spring member 51 therebetween in a combined state. As shown in FIGS. 2 and 6 , the spring accommodation space 35 is formed in a size corresponding to the size of the spring member 51 so that the spring member 51 deforms without much play when the handle 3 is opened and closed. In addition, as shown in FIG. 7 , the rear end portion of the spring accommodation space 35 communicates with the cylinder inner space 342 of the connection member 341 in the connection portion 34 described later. Thus, the spring member 51 is extended to the pair of sub-handle parts 33 via the connection part 34 as shown in FIG. 2 .

The case portion 334 is made of ABS resin. In addition, chrome plating is applied to the surface of the case portion 334, and the surface has electrical conductivity. Also, the surface of the case portion 334 is electrically connected to the solar cell panel 6 .

As shown in FIGS. 5 and 6 , the connection portion 34 that connects the pair of sub-handle portions 33 includes a connection member 341 , a restriction plate 71 , and a restriction pin 72 . The restricting plate 71 and the restricting pin 72 have two functions: a function as the connecting portion 34 connecting the pair of sub-handle portions 33 and a function as an opening/closing restricting member restricting the upper limit of the distance d between the pair of rollers 4 . In addition, the restricting plate 71 has a function as a reinforcing member that suppresses displacement of the pair of sub-handle portions 33 in directions other than the opening and closing direction.

The connecting member 341 is made of an elastic body, and has an opening end 343 and an intervening portion 344 as shown in FIGS. 5 to 7 . The intervening part 344 is disposed between the pair of sub handle parts 33 . The opening end portion 343 is erected on both sides in the lateral direction of the intervening portion 344 and has a cylindrical shape.

As shown in FIGS. 6 and 7 , the rear end 332 a of the lower spring receiving portion 332 and the rear end 333 a of the upper spring receiving portion 333 are inserted into the respective opening ends 343 . In addition, as shown in FIGS. 5 and 7 , the cylinder space 342 existing inside the intervening portion 344 and the opening end portion 343 communicates with the spring accommodating space 35 in a state attached to the communicating sub-handle portion 33 .

As shown in FIGS. 6 and 7 , there is a flange portion 345 extending outward on the front end side of the opening end portion 343 , and a concave engagement portion 346 is formed between the flange portion 345 and the insertion portion 344 . The rear end 331 a of the base portion 331 and the rear end 334 a of the shell portion 334 are engaged with the concave engaging portion 346 . Accordingly, the connection member 341 is configured to expand and contract as the sub-handle portion 33 is opened and closed.

The restricting plate 71 is arranged along the substantially U-shape of the rear end portion of the handle 3 . As shown in FIGS. 2 and 8 , the restricting plate 71 is made of a metal plate, and has a bridge portion 712 passing through the connection member 341 and an arm portion 713 extending from the bridge portion 712 toward each sub-handle portion 33 . As shown in FIG. 8 , the arm portion 713 has a substantially rectangular pin insertion hole 711 at the front end, and has a boss insertion hole on the bridge portion 712 side (rear) than the pin insertion hole 711 . 714.

As shown in FIGS. 6 and 8 , the restricting pin 72 made of metal is disposed through the pin insertion hole 711 . As shown in FIG. 6 , the restriction pin 72 is formed in a cylindrical shape having a smaller outer diameter than the pin insertion hole 711 . In addition, end portions in the vertical direction of the restriction pin 72 are fixed to the base portion 331 and the case portion 334 . Therefore, with the opening and closing operation of the handle 3, the position of the restriction pin 72 is changed with the opening range of the pin insertion hole 711 as a limit ( FIG. 8 , arrow 101 ).

In addition, as shown in FIG. 7 , the boss 336 erected on the case portion 334 is inserted into the boss insertion hole 714 . Therefore, the restricting plate 71 is held in a certain position relative to the boss 336 . In addition, when opening and closing the handle 3, the sub-handle part 33 turns around the boss 336 (FIG. 8, arrow 102).

As shown in FIGS. 2 and 5 to 7, the spring member 51 is composed of a metal rod bent into a substantially U-shape, and is disposed so as to pass through both the spring receiving space 35 of the sub-handle portion 33 and the cylindrical space 342 of the connecting member 341. By. In addition, the spring member 51 deforms as the handle 3 is opened and closed, and in the deformed state, the spring member 51 urges in the direction of returning to the natural state to press the wall surface of the spring accommodation space 35 . Thus, the biasing force of the spring member 51 is transmitted to the pair of rollers 4 via the sub-handle portion 33 .

Next, the operation|movement of the opening and closing regulator of the cosmetics device 1 of this example and the usage method of the cosmetics device 1 are demonstrated together. When using the beauty device 1 , the user holds the grip part 32 so that light enters the solar cell panel 6 while bringing the shell part 334 of the sub-handle part 33 into contact with the palm of the user's palm. 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 in this way, the plane P including the pair of axes A is inclined with respect to the skin surface 8 .

By further strengthening the force of pressing the pair of rollers 4 from the state where the pair of rollers 4 are in contact with the skin surface 8, the handle 3 can be opened against the applied force of the spring member 51 (Figure 8, arrow 102), and the pair of rollers can be enlarged. The spacing d of the rollers 4 ( FIG. 4 , arrow 100 ). The pair of shafts 2 in the beauty device 1 of this example are configured to maintain the distance d from the handle 3 side when the distance d between the pair of rollers 4 is in either the state changed from the natural state or the natural state. The base part is a developed state in which the distance between the pair of axes A is widened toward the front end side. That is, the cosmetics device 1 of this example is comprised in the unfolded state always.

At this time, the restricting plate 71 and the restricting pin 72 function as an opening/closing restricting member as follows. Inside the sub-handle part 33, the limiting pin 72 fixed on the base part 331 and the shell part 334 moves to the outside of the lateral direction (Fig. 8, arrow 102) along with the handle 3 from the natural state (Fig. 8, arrow 102). 101). Furthermore, if the restriction pin 72 comes into contact with the end edge of the pin insertion hole 711, the handle 3 cannot be further opened.

The restriction plate 71 and the restriction pin 72 in the beauty device 1 of this example are designed so that the distance d of a pair of roller 4 can be changed in the range of 1-50 mm when opening and closing the sub-handle part 33. On the other hand, the base part 331 of the cosmetics device 1 of this example consists of ABS resin. Therefore, by increasing the force pressing the pair of rollers 4 against the skin surface 8, the sub-handle portion 33 can be elastically deformed so that the distance d between the pair of rollers 4 becomes wider beyond the above-mentioned specified range. In the beauty device 1 of this example, when elastically deforming the sub-handle part 33 in actual use, the maximum value of the space|interval d of a pair of roller 4 is 65 mm.

In the state where the pair of rollers 4 are in contact with the skin surface 8, by moving the beauty device 1 from the side of the rollers 4 to the direction towards the side of the handle 3, as shown in Figures 3 and 4, the cosmetic effect to be obtained can be obtained. The part of the skin is entangled between a pair of rollers 4, and the skin surface 8 is pulled by the pair of rollers 4 to deform the skin surface.

At this time, by applying force in the direction to close the handle 3 while moving the cosmetics device 1 , the pressing force applied to the part sandwiched between the pair of rollers 4 can be increased.

In addition, in addition to the usage method shown in FIG. 3 and FIG. 4 , for example, as shown in FIG. 9 , it is also possible to reciprocate the beauty device with the upper arm, forearm, calf, etc. sandwiched between the pair of rollers 4 1 to use.

In addition, when the roller 4 is in contact with the skin surface 8, and the shell portion 334 of the handle 3 is in contact with the palm, a closed loop including the solar panel 6, the roller 4, the shell portion 334 and the human body is formed. Therefore, by utilizing the electromotive force of the solar cell panel 6 , current can be made to flow on the skin of the human body in contact with the roller 4 .

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

The beauty device 1 has a pair of roller 4 and the spring member 51 as the urging tool 5 comprised so that the mutual space|interval d can be changed. Therefore, the cosmetics device 1 can be suitably used from parts with relatively large ups and downs, such as the face and arms, to parts with relatively small ups and downs, such as the abdomen. In addition, since the distance between the pair of rollers 4 can be changed, as shown in an example in FIG. 9 , it is also possible to use the pair of rollers 4 with the arms and legs sandwiched between the pair of rollers 4 . Thus, by sandwiching an arm etc. between a pair of roller 4, and making the cosmetics device 1 reciprocate and rotating the roller 4, the massage effect to a muscle can be acquired effectively.

In addition, in the beauty device 1 , in a state where the distance d between the pair of rollers 4 is widened, the urging force by the urging member 5 acts on each roller 4 and urges the pair of rollers 4 in a direction to approach each other. Therefore, effects such as promoting blood circulation and activating metabolism of the skin at the portion pressed by the pair of rollers 4 can be expected, and further cosmetic effects such as beautifying the skin can be expected.

Moreover, the cosmetics device 1 has the control board 71 and the control pin 72 which are opening and closing control means. Therefore, the cosmetics device 1 can reliably prevent that the space|interval d of a pair of roller 4 becomes too wide, and can prevent damage of the cosmetics device 1 reliably.

In addition, the pair of shaft portions 2 are arranged 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 front end side at all times. That is, the cosmetics device 1 realizes the above-mentioned unfolded state in a natural state, so that it is easier for the user to handle. In addition, by realizing the above-described unfolded state in a state where the distance d between the pair of rollers 4 is changed from the natural state, the pressing force felt at the portion sandwiched between the pair of rollers 4 can be moderately increased, and a more excellent performance can be expected. Cosmetic effect.

In addition, the handle 3 has a pair of sub-handle parts 33 each supporting the shaft part 2 and a connection part 34 connecting the pair of sub-handle parts 33 . Furthermore, the pair of shaft portions 2 and the coupling portion 34 are provided on opposite ends of the sub-handle portion 33 . Therefore, the user can change the interval d between the pair of rollers 4 by adjusting the degree of opening and closing of the sub-handle portion 33 , and can easily adjust the pressing force applied to the portion to obtain a cosmetic effect. As a result, the ease of handling of the cosmetics device 1 can be further improved, and at the same time, a more excellent cosmetic effect can be expected.

In addition, the handle 3 is inclined with respect to a plane P including a pair of axes A. As shown in FIG. Further, in this example, the restricting plate 71 and the restricting pin 72 are designed so that the distance d between the pair of rollers 4 can be changed within a range of 1 to 50 mm when the sub-handle portion 33 is opened and closed. By keeping the distance d between the pair of rollers 4 within an appropriate range, the aforementioned skin lifting effect can be reliably felt. As a result, a more excellent cosmetic effect can be expected.

In addition, the roller 4 has a substantially spherical shape. Therefore, the pressing force from the roller 4 is easy to concentrate, and it is easy to make the pressing force felt by the user sufficiently large. In addition, the operation of rotating the pair of rollers 4 while pressing against the skin can be performed more smoothly, and the ease of handling of the cosmetics device 1 can be further improved.

In addition, the handle 3 has a solar cell panel 6 , and is configured to allow current to flow to the human skin in contact with the roller 4 by using the electromotive force of the solar cell panel 6 . Therefore, a more excellent cosmetic effect can be expected by using the cosmetics device 1 .

In addition, in this example, since the solar cell panel 6, the roller 4, and the shell portion 334 arranged on the same sub-handle portion 33 are connected to each other, a closed circuit including human skin can be formed on each of the sub-handle portions 33. . As a result, poor contact between the roller 4 and the shell portion 334 and the skin of the human body can be suppressed. Therefore, a more excellent cosmetic effect can be expected by using the cosmetics device 1 .

In addition, since the sub-handle part 33 of this example has a substantially elliptical cross-section in the front-rear direction, it has structurally high rigidity. Also, the sub-handle portion 33 is reinforced by the restricting plate 71 made of a metal plate, which has higher rigidity than the case without the restricting plate 71 . By having these structures, the cosmetics device 1 can sufficiently increase the pressing force applied by the pair of rollers 4 to the part where the cosmetic effect is to be obtained even when the sub-handle part 33 is elastically deformed.

In the case where the rigidity of the sub-handle part 33 is too low, the sub-handle part 33 may be bent if the part to which the cosmetic effect is to be obtained is pressed by the pair of rollers 4 . Therefore, depending on the situation, the distance d between the pair of rollers 4 cannot be sufficiently narrowed even if the handle 3 is opened and closed, and the pressing force applied to the portion to be obtained with a cosmetic effect may not be sufficiently felt. On the other hand, the beauty device 1 of this example can avoid this problem by having the above-mentioned structure, and the pressing force applied to the part to obtain the beauty effect can be sufficiently increased by the opening and closing operation of the handle 3 . As a result of the above, according to the cosmetics device 1, the pressing force which can feel can be fully increased, and the more excellent cosmetics effect can be expected.

In addition, the connection part 34 has the connection member 341 expandable and contractible with opening and closing of the pair of sub-handle parts 33. As shown in FIG. Furthermore, the connecting member 341 is made of an elastic body having rubber elasticity. Therefore, the durability of the coupling portion 34 against repeated opening and closing operations of the sub-handle portion 33 can be improved. As a result, the damage of the connection part 34 can be suppressed, and the cosmetics device 1 can be used continuously for a long time.

In addition, the connection portion 34 has a restriction plate 71 , and the restriction plate 71 has a bridge portion 712 . Furthermore, the bridge part 712 is comprised by the metal plate, and is comprised so that displacement of the pair of sub-handle parts 33 to directions other than the opening and closing direction can be suppressed. Therefore, the twisting force, the bending force, etc. which are applied to the connection part 34 can be reduced, and the damage of the connection part 34 can be suppressed.

In addition, each sub-handle portion 33 is engaged with a pin insertion hole 771 and a boss insertion hole 714 provided in the restriction plate 71 via the bosses 336 and the restriction pins 72 provided at intervals in the longitudinal direction. In this way, since each sub-handle part 33 engages with the restriction plate 71 at two or more places in the longitudinal direction, the beauty device 1 can effectively suppress displacement of the sub-handle part 33 in the direction of applying a twisting force to the connection part 34 .

In addition, the restriction plate 71 has an arm portion 713 extending from the bridge portion 712 along the longitudinal direction of each sub-handle portion 33 . Therefore, it is possible to effectively suppress displacement of the sub-handle portion 33 in a direction in which a torsional force is applied to the coupling portion 34 . As a result, the damage of the connection part 34 can be suppressed, and the durability of the cosmetics device 1 can be improved more.

As mentioned above, the beauty device 1 can be used suitably for each part of a body, and can expect the outstanding cosmetic effect.

(Example 2)

This example is an example of the cosmetics device 1 which has the sub-handle part 36 which raised rigidity, reducing the number of parts. In addition, although not shown in figure, the outer shape of the cosmetics device 1 of this example is the same as Example 1.

As shown in FIG. 10 , the sub-handle portion 36 is constituted by three members of a base portion 361 , a spring receiving portion 362 , and a case portion 363 . The spring housing portion 362 and the case portion 363 are disposed on the rear half of the base portion 361 and connected to the base portion 361 by screws (not shown). In addition, in FIG. 10, description of the roller 4, the restriction pin 72, the screw, etc. is abbreviate|omitted for convenience.

As shown in FIGS. 10 and 11 , the base portion 361 has a rib 364 for improving rigidity at a portion overlapping the spring receiving portion 362 . As a result, the rigidity of the base portion 361 itself can be improved, and further the rigidity of the sub-handle portion 36 can be further enhanced.

A spring accommodation space 35 that accommodates the spring member 51 is formed between the base portion 361 and the spring accommodation portion 362 . As shown in FIG. 12 , the spring accommodating space 35 of this example is formed by providing a recess corresponding to the size of the spring member 51 in the spring accommodating portion 362 .

In addition, in this example, as shown in FIG. 12 , on the rear end of the spring receiving portion 362 , that is, on the portions facing each other in the state where the connecting portion 34 is inserted, there is provided a restriction functioning as an opening and closing restriction member. Convex part 365.

The regulating convex portion 365 is configured such that the apex 366 provided substantially in the center in the front-rear direction abuts against each other in a natural state. Moreover, the restriction convex part 365 has the inclined surface 367 (367a, 367b) which recedes to the outer side of a lateral direction as it goes to the front-back direction from the top part 366. As shown in FIG. As shown in FIG. 12 , the inclined surface 367a in the one spring receiving portion 362 is disposed so as to be spaced apart from the inclined surface 367a in the other spring receiving portion in a natural state. Similarly, the inclined surface 367b in one spring receiving portion 362 is arranged to be spaced apart from the inclined surface 367b in the other spring receiving portion in a natural state.

The regulating convex portion 365 configured in this way functions as an opening and closing regulating member as described below. That is, when the handle 3 is opened, the pair of sub handle parts 36 rotates around the boss 368 inserted into the boss insertion hole 714 (not shown) of the restricting plate 71 (FIG. 12, arrow 103). At this time, as the sub-handle part 36 turns, the inclined surfaces 367a on the rear side of the regulating convex part 365 approach each other, and finally the inclined surfaces 367a come into contact with each other. Then, as shown in FIG. 13 , the handle 3 cannot be further opened with the state where the inclined surfaces 367 a on the rear side contact each other as a limit. In this way, by restricting the opening and closing operation of the handle 3 with the position where the inclined surfaces 367a contact each other as the upper limit, the upper limit of the range in which the distance d between the pair of rollers 4 can be changed can be restricted.

In addition, in this example, the lower limit at the time of closing the handle 3 is regulated by the inclined surface 367 b on the front side of the regulating convex portion 365 . That is, similarly to the above, when the handle 3 is closed, the inclined surfaces 367b on the front side approach each other while the sub-handle portion 36 is turned. Then, if the operation of closing the handle 3 is continued, the inclined surfaces 367b finally contact each other, and the handle 3 cannot be further closed with the state where the inclined surfaces 367b on the front side contact each other as a limit. In this way, by restricting the opening and closing operation of the handle 3 with the position where the inclined surfaces 367b contact each other as the lower limit, the lower limit of the range of the variable distance d between the pair of rollers 4 can be restricted.

In addition, although not shown in figure, in this example, the length of the arm part 713 of the restriction plate 71 is tripled compared with Example 1. FIG. The rigidity of the sub handle part 36 can be further improved by making the arm part 713 longer.

Other structures are the same as in Embodiment 1. Note that, among the symbols used in FIGS. 10 to 13 , the same symbols as those used in Embodiment 1 denote the same components as in Embodiment 1 unless otherwise specified.

As shown in this example, by using the base portion 361 having the rib 364 in the sub-handle portion 36 and further lengthening the arm portion 713 of the restricting plate 71, the rigidity of the sub-handle portion 36 can be further improved. As a result, displacement of the sub-handle portion 36 in the direction in which a torsional force is applied to the connection portion 34 can be more effectively suppressed, and damage to the connection portion 34 can be suppressed.

In addition, in Embodiment 1 and Embodiment 2, although the structure using the restricting plate 71 and the restricting pin 72 as the opening and closing restricting member and the structure in which the restricting convex portion 365 is provided on the sub-handle portion 36 are described, it is also possible to use other structures. For example, there is also a structure in which the pair of sub-handle parts 36 are connected by a chain or the like, and the openable and closable range of the pair of sub-handle parts 36 is limited to the extension range of the chain.

(Example 3)

This example is an example of the cosmetics device 1b having the sub-handle part 37 formed from a single resin molded body. As shown in FIG. 14 , the beauty device 1 b of this example has a handle 3 and a roller 4 , wherein the handle 3 has a pair of sub-handle parts 37 that respectively support the shaft part and a connecting part 34 that connects the pair of sub-handle parts 37 in an openable and closable manner. The rollers 4 are respectively provided on the shafts, and are rotatably supported around the axes of the shafts. In addition, the connection part 34 has the connection member 38 expandable and contractible with opening and closing of the pair of sub-handle parts 37. As shown in FIG.

As shown in FIG. 14, the outer shape of the cosmetics device 1b of this example is the same as the cosmetics device 1 of Example 1. As shown in FIG. In addition, the symbols used in FIG. 14 are the same as those used in Example 1, and unless otherwise specified, indicate the same components as in Example 1, and the like.

The sub handle portion 37 is a single resin molded body formed of ABS resin. That is, the sub-handle part 37 of this example is not divided into a plurality of parts like the first embodiment, nor does it incorporate the solar battery panel 6, the spring member 51, and the like. Although not shown, when molding the sub-handle part 37, the shaft part is fixed to the shaft support part 31 by insert molding.

The connecting portion 34 is constituted only by the connecting member 38 . As shown in FIG. 15 , the connection member 38 is formed of an elastic body, and has an intervening portion 381 disposed between the pair of sub-handle portions 37 and columnar portions 382 erected on both sides of the intervening portion 381 .

On the front end side of the columnar portion 382 , there is a flange portion 383 extending outward, and a concave engaging portion 384 is formed between the flange portion 383 and the intervening portion 381 . The rear end 371 of the sub-handle portion 37 is engaged with the concave engaging portion 384 , and the connecting member 38 is configured to expand and contract as the sub-handle portion 37 is opened and closed, as in the first embodiment.

Thus, even if the connection part 34 is comprised only by the connection member 38, if the connection member 38 can expand and contract with opening and closing of the sub-handle part 37, the effect of improving the durability of the cosmetics device 1b can be acquired.

(Example 4)

As shown in FIG. 16, this example is an example of the cosmetics device 1c provided with the connection member 39 which has a bellows structure. The connection member 39 has a cylindrical shape, and a portion disposed between the pair of sub-handle portions 33 has a bellows structure. Although not shown, the rear end 331a of the base portion 331 and the rear end 334a of the case portion 334 are engaged with both ends of the connection member 39 similarly to the first embodiment. Accordingly, the connection member 39 is configured to expand and contract as the sub-handle portion 33 is opened and closed. In addition, a restricting plate 71 and a spring member 51 are arranged inside the cylinder of the connection member 39 . Other structures are the same as in Embodiment 1. Note that, among the symbols used in FIG. 16 , the same symbols as those used in Embodiment 1 represent the same constituent elements as in Embodiment 1, and the like.

As in this example, the connecting member 39 used in the connecting portion 34 may have a stretchable structure such as a bellows structure, for example. In this case, a material having no rubber elasticity such as polypropylene may be used as the material constituting the connection member 39 . In addition, an elastic body may be used for the material of the connection member 39 which has a bellows structure.

(Example 5)

This example is an example of the electrical connection of the solar cell panel 6, the roller 4, and the case part 334 in the cosmetics device 1. As shown in FIG. In the beauty device 1 of this example, the working electrode 41 provided on the surface of the roller 4 and the counter electrode 337 provided on the surface of the shell part 334 are electrically connected to the solar cell panel 6 . Therefore, during the period when the counter electrode 337 is in contact with the skin surface 8, and the counter electrode 337 of the handle 3 is in contact with the palm 81, as shown in FIG. The closed loop of the solar cell panel 6 can flow current to the skin of the human body in contact with the roller 4 by using the electromotive force of the solar cell panel 6 .

As shown in FIGS. 17 to 19 , the roller 4 supported by the handle 3 is a polyhedron composed of a plurality of triangles and has a substantially spherical shape. Titanium plating is applied to the surface of the roller 4, and a working electrode 41 formed of a titanium plating film having electrical conductivity is provided.

As shown in FIG. 18 , the roller 4 is supported on the handle 3 via the shaft portion 2 and the bearing 21 mounted on the shaft portion 2 . The bearing 21 is made of conductive resin, and is in contact with the working electrode 41 in a state where the roller 4 is attached. The working electrode 41 is electrically connected to the solar cell panel 6 described later via the bearing 21 and the shaft portion 2 .

In addition, an O-ring receiving portion 22 having a thicker outer diameter than the surrounding area is formed approximately at the central portion in the longitudinal direction of the shaft portion 2 , and an O-ring receiving portion 22 and the shaft supporting portion 31 are sandwiched between the O-ring receiving portion 22 and the shaft support portion 31 . Ring 23. This prevents moisture and the like from infiltrating into the handle 3 from between the handle 3 and the roller 4 .

The shaft portion 2 is buried in the base portion 331 in the following steps. First, a cup-shaped O-ring retainer 24 made of the same material as that of the base 331 is prepared. Next, the O-ring 23 and the O-ring holder 24 are sequentially attached to the shaft portion 2 , and the O-ring 23 is sandwiched between the O-ring holder 24 and the O-ring receiving portion 22 . The shaft portion 2 in this state is embedded in the base portion 331 by insert molding. As described above, as shown in FIG. 18 , the shaft portion 2 may be embedded in the shaft support portion 31 .

In addition, as shown in FIG. 19 , in the vicinity of the shell portion 334 of the base portion 331 , an electric conduction pin 65 is embedded. As will be described later, the current conduction pin 65 forms a part of the current path between the solar cell panel 6 and the counter electrode 337 . The conduction pin 65 is buried in the base part 331 in the same procedure as that of the shaft part 2 is buried. First, a cup-shaped O-ring receiver 651 and a plate-shaped O-ring retainer 652 made of the same material as the base portion 331 are prepared. Next, install the O-ring receiving part 651, the O-ring 653, and the O-ring pressing part 652 on the power supply pin 65 in sequence, so that the O-ring 653 is clamped between the O-ring pressing part 652 and the O-ring receiving part. 651 states between. The conduction pin 65 in this state is embedded in the base portion 331 by insert molding. As described above, the conduction pin 65 may be embedded in the base 331 . The O-ring 653 attached to the conduction pin 65 prevents water or the like from entering the solar cell panel 6 side from the rear (the case portion 334 side).

As described above, by pre-installing the O-ring 23 and the O-ring 653 together with the O-ring presser 24 and the like on the shaft part 2 and the like, and then fixing them to the base part 331 by insert molding, even narrow and intricate It is also possible to ensure waterproofness easily and reliably for the part of the structure. That is, by installing the O-ring 23 and the like on the shaft portion 2 and the conduction pin 65 in advance, the O-ring 23 can be easily and reliably attached to the shaft portion 2 and the like compared with the case where the O-ring 23 and the like are installed after the shaft portion 2 and the like are fixed. and so on are configured at the specified positions. Furthermore, since the O-ring 23 and the like are fixed at predetermined positions by performing insert molding in this state, reliable waterproofness can be obtained.

In addition, by using a material compatible with the base 331 for the O-ring holder 24 and the like, the O-ring holder 24 and the base 331 can be welded to each other during insert molding. Thereby, the gap between the O-ring holder 24 and the like and the base 331 can be sealed, and waterproofness can be further improved.

As shown in FIG. 19 , solar cell panel 6 has a structure in which lens cover 61 , solar cell 62 , first unit support 63 , and second unit support 64 are sequentially stacked, and lens cover 61 is exposed on the upper surface of base 331 . A gasket 611 is sandwiched between the lens cover 61 and the base 331 to prevent moisture and the like from entering through a gap between the lens cover 61 and the base 331 . In addition, the solar battery panel 6, the roller 4, and the case portion 334 provided on the same sub-handle portion 33 are electrically connected to each other. That is, the terminal 621 on one side of the solar cell 62 is electrically connected to the working electrode 41 provided on the surface of the roller 4 via the shaft portion 2 and the bearing 21 .

In addition, chromium plating is applied to the surface of the case portion 334, and a counter electrode 337 formed of an electrically conductive chromium plating film is provided as shown in FIGS. 17 and 19 . The terminal 622 on the other side of the solar cell 62 is electrically connected to the counter electrode 337 via the conduction pin 65 and the conduction spring 66 .

In this example, the solar cell panel 6 , the working electrode 41 and the counter electrode 337 arranged on the same sub-handle part 33 are connected to each other, and a closed circuit including human skin can be formed on each sub-handle part 33 .

That is, as shown in an example in FIG. 17, a pair of sub-handle parts 33 (33a, 33b) has solar cell panel 6 (6a, 6b) and counter electrode 337 (337a, 337b), respectively. And, under the state that a pair of rollers 4 is in contact with skin surface 8, solar cell panel 6, working electrode 41 (41a, 41b) and counter electrode 337 form the annular first current path that includes first solar cell panel 6a. i1 is connected in the form of a ring-shaped second current path i2 including the second solar panel 6b. Furthermore, although an example in which the positive pole of the solar cell panel 6 is connected to the working electrode 41 and the negative pole is connected to the counter electrode 337 has been shown in FIG. In the case of a connected structure, two current paths i1 and i2 may be formed. Other structures are the same as in Embodiment 1. Note that, among the symbols used in FIGS. 17 to 19 , the same symbols as those used in Embodiment 1 represent the same components as in Embodiment 1 unless otherwise specified.

In the beauty device 1, since the solar cell panel 6 is provided on the sub-handle portion 33 provided with the roller 4 having the working electrode 41, it is not necessary to provide wiring and circuits for connecting the solar cell panel 6 and the working electrode 41, etc. in the connection portion 34. parts etc. Therefore, with the opening and closing of the sub-handle portion 33, it is possible to avoid stress on the wiring connecting the solar cell panel 6 and the working electrode 41, etc., and to avoid problems such as poor contact and disconnection of the wiring. As a result, poor contact between the roller 4 and the shell portion 334 and the skin of the human body can be suppressed, and an excellent cosmetic effect lasting for a long time can be expected.

In addition, in the state where the pair of rollers 4 are in contact with the skin, an annular current path i1 passing through the solar cell panel 6, the working electrode 41, the skin surface 8 sandwiched between the pair of rollers 4, the palm 81, and the counter electrode 337 is formed in sequence. and i2. Therefore, a weak current can be efficiently passed through the contact portions between the working electrode 41 and the skin surface 8 in the first current path i1 and the second current path i2 . As a result, a more excellent cosmetic effect can be expected.

In addition, the solar battery panel 6 is provided between the grip part 32 held by the user and the shaft support part 31 that supports the shaft part 2 among the sub handle parts 33 . Therefore, when the user uses the cosmetics device 1, by holding the grip part 32, the solar cell panel 6 is hard to be covered by the shadow of a hand or an arm. Therefore, it is difficult to cut off the power supply to the working electrode 41, and the ease of handling of the cosmetics device 1 can be further improved. In addition, the same operation and effect as in Example 1 can be produced.

(Example 6)

This example is an example of the cosmetics device 1 comprised so that two solar cell panels 6 (6a, 6b) may be connected in series in the state which contacted the skin with the pair of roller 4.

As shown in FIG. 20, the cosmetics device 1 of this example has solar cell panels 6a, 6b and counter electrodes 337a, 337b on a pair of child handle parts 33a, 33b, respectively. The positive electrode of the solar cell panel 6a provided on one sub-handle part 33a is connected to the working electrode 41a of the roller 4a, and the negative electrode is connected to the counter electrode 337a. In addition, the positive electrode of the solar cell panel 6b provided on the other sub-handle part 33b is connected to the counter electrode 337b, and the negative electrode is connected to the working electrode 41b of the roller 4b. Other structures are the same as in Embodiment 5. In addition, among the code|symbol used in FIG. 20, the same code|symbol used in Example 5 shows the same component element etc. as Example 5 unless otherwise specified.

In the beauty device 1 of this example, the solar cell panel 6, the working electrode 41, and the counter electrode 337 are connected as mentioned above. Therefore, in a state where the pair of rollers 4 are in contact with the skin, one loop current path i3 including both solar cell panels 6 is formed. The current path i3 , as shown in FIG. 20 , includes a pair of solar cell panels 6 , a pair of working electrodes 41 and a pair of counter electrodes 337 . Furthermore, the conduction between the pair of working electrodes 41 is established by the skin surface 8 sandwiched between the pair of rollers 4 , and the conduction between the pair of counter electrodes 337 is established by the palm 81 . Therefore, the path length of the current path i3 can be shortened, and at the same time, the electromotive force generated by the solar cell panel 6 can be easily increased. As a result, it is possible to more reliably and efficiently circulate a weak current on the skin surface 8 sandwiched between the pair of rollers 4, and a more excellent cosmetic effect can be expected. In addition, the same effect as that of Example 5 can be produced.

Moreover, although the examples in which the working electrode 41 and the solar cell panel 6 are arranged on both the sub-handle parts 33a and 33b have been shown in Embodiment 5 and Embodiment 6, the working electrode 41 and the solar cell panel 6 may be arranged on only one. On the sub-handle part 33.

In addition, although the example of the beauty device 1 that uses the solar cell panel 6 to supply power to the working electrode 41 has been shown in Embodiment 5 and Embodiment 6, it is also possible to use a primary battery or a secondary battery instead of the solar cell panel 6 as power supply. Moreover, the cosmetics device 1 may have the control circuit which controls the magnitude|size and polarity of electric current, etc. as needed.

In the case of using a primary battery or a secondary battery as a power source, the sub-handle portion 33 may be configured to house these batteries therein. In addition, these batteries may be detachably attached to the outer peripheral surface of the sub-grip portion 33 .
