As this kind of beauty device, it has a main body part that has a bifurcated shape and a roller attached to the tip of the main body part, respectively, 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).

JP-A-2007-130327

However, in the beauty device of Patent Document 1, it is necessary to generate a pressing force applied to each part of the body by a pair of rollers by the grip strength of the user. Therefore, it is difficult to keep the pressing force applied to the body constant, and there is a problem that the effects such as promoting blood circulation of the skin in the pressed portion and activating metabolism cannot be fully experienced.

The present invention has been made in view of such a background, and an object of the present invention is to provide a cosmetological device that can be suitably used for various parts of the body and can be expected to have an excellent cosmetological effect.

One aspect of the present invention is a handle having a pair of shafts and a handle.
A cosmetology device including rollers that are arranged on the shafts, are rotatably supported around the shafts of the shafts, and are configured so that the distance between them can be changed .
The beauty device
An urging means for generating an urging force for returning the distance between the pair of rollers to a natural state,
It has an opening / closing regulating means that regulates the upper limit of the interval between the pair of rollers in order to prevent the beauty device from being damaged .
In the natural state, the pair of shafts are arranged so as to be in an expanded state in which the distance between the pair of shafts increases from the base on the handle side toward the tip side.
The handle is in a cosmetologist characterized in that it is tilted with respect to a plane including the pair of axes.

The beauty device has the pair of rollers which are arranged on the shaft portion and are rotatably supported around the axis of the shaft portion. Further, the pair of rollers are configured so that the distance between them can be changed. Further, it has an urging means for generating an urging force for returning the distance between the pair of rollers to a natural state. That is, while the distance between the pair of rollers is variable, the pair of rollers are configured to receive an urging force to return to the distance in the natural state when the distance between the rollers is changed from the natural state.

Therefore, by pressing the pair of rollers against the portion where the beauty effect is desired, the user widens the distance between the pair of rollers against the urging force according to the shape of the portion where the beauty effect is desired. The distance between the pair of rollers can be appropriately adjusted according to the shape of the portion to be used. As a result, the beauty device can be suitably used from a relatively large undulating portion such as the face and arms to a relatively small undulating portion such as the abdomen.

Further, in the beauty device, when the distance between the pair of rollers is widened, the urging force by the urging means acts on each of the rollers, and the pair of rollers are urged in a direction approaching 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 in the pressed portion of the skin and activating metabolism can be expected, and eventually, beauty effects such as beautifying the skin can be expected.

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

The front view of the cosmetology device in Example 1 as viewed from the roller side. The exploded perspective view of the cosmetology device in Example 1. FIG. 2 is a cross-sectional view taken along the line VI-VI of FIG. FIG. 2 is a cross-sectional view taken along the line VII-VII of FIG. The explanatory view of the operation of opening the handle of a beauty device in Example 1. FIG. 2 is a side view of the beauty device according to the second embodiment. Top view of the base portion in the second embodiment. The bottom view of the spring accommodating portion in Example 2. FIG. 2 is a bottom view of the spring accommodating portion in the state where the handle is opened to the upper limit in the second embodiment.

In the beauty device, the natural state means a state in which the beauty device is not used and a portion for which a beauty effect is desired is not sandwiched between a pair of rollers.

The cosmetic device has a closing restricting means for restricting the upper limit of the spacing of the pair of rollers. By providing the opening / closing regulating means, the beauty device can surely prevent the distance between the pair of rollers from becoming excessively wide. As a result, damage to the beauty device can be reliably prevented.

The distance between the pair of rollers is preferably regulated to 50 mm or less, more preferably 35 mm or less, and even more preferably 20 mm or less by the opening / closing regulating means. On the other hand, the lower limit of the distance between the rollers may not be regulated, but if the pressing force felt in the portion sandwiched between the pair of rollers becomes excessively large, it is regulated by the opening / closing regulating means or other means. You may be.

As a configuration in which the distance between the pair of rollers can be changed, for example, there is a configuration in which the shaft portion is assembled to the handle in a state where the shaft portion can be opened and closed. In this case, the distance between the pair of rollers can be changed according to the opening / closing operation of the shaft portion. Further, in the case of adopting the above configuration, as the opening / closing regulating means, for example, a member for regulating the upper limit of the opening / closing range of the shaft portion can be provided. That is, by providing the member at a position where it comes into contact with the shaft portion that is more open than the natural state, the upper limit of the opening / closing range of the shaft portion is regulated according to the position of the member. As a result, the upper limit of the distance between the pair of rollers can be regulated.

Further, the handle has a pair of sub-handle portions that support the shaft portions and a connecting portion that connects the pair of sub-handle portions so as to be openable and closable. The pair of shaft portions and the connecting portion are connected. Is preferably provided at the ends of the sub-handle portion on opposite sides to each other. 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 becomes easy for the user to intuitively grasp the relationship between the magnitude of the opening / closing operation of the handle and the amount of change in the interval between the pair of rollers. Further, by adjusting the degree of opening and closing of the sub-handle portion, the pressing force applied to the portion where the beauty effect is desired can be easily adjusted. As a result, the ease of handling of the beauty device can be further improved, and a more excellent beauty effect can be expected.

When the handle has the sub-handle portion and the connecting portion, as the opening / closing restricting means, for example, a member that regulates the upper limit of the opening / closing range of the sub-handle portion can be provided. That is, by providing the member at a position where it comes into contact with the sub-handle portion that is more open than the natural state, the upper limit of the opening / closing range of the sub-handle portion is regulated according to the position of the member. As a result, the upper limit of the distance between the pair of rollers can be regulated.

Further, when the beauty device has the above-mentioned configuration, the sub-handle portion itself may be configured to function as the above-mentioned opening / closing restricting means. As the above configuration, for example, there is a configuration in which a part of the sub-handle portions in a state more open than in the natural state abuts on each other. The opening / closing range of the sub-handle portions configured in this way is restricted so that the state of contact with each other is the upper limit. As a result, the upper limit of the distance between the pair of rollers can be regulated.

Further, when the beauty device has the above configuration, the opening / closing regulating means may be provided at the connecting portion. In this case, since the connecting portion and the opening / closing regulating means related to the opening / closing operation of the sub-handle portion are collectively arranged at one place, the degree of freedom in designing the beauty device is further increased. Further, by combining the connecting portion and the opening / closing regulating means in one place, the ease of handling of the beauty device can be further improved.

The pair of shaft portions, in the natural state, are arranged so as to be expanded state interval of the pair of axial spread toward the tip end side from the base of the handle side. Therefore , when the beauty device is pressed against the skin, the distance between the pair of rollers can be easily expanded. As a result, the cosmetological device becomes easier for the user to handle.

Further, in the natural state, the pair of rollers may be separated from each other. In this case, when the pair of rollers are pressed against the portion where the beauty effect is desired, a state in which the portion is sandwiched between the 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, the distance between the pair of rollers is opposed to the urging force in order to realize a state in which the portion is sandwiched between the rollers. Need to spread. Therefore, in the natural state, the beauty device in which the pair of rollers are separated from each other can more easily perform the operation of sandwiching the portion for which the beauty effect is desired between the rollers, which is more suitable for the user. It will be easy to handle. 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 in the range of 1 to 50 mm.

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

Further, the handle is that are inclined relative to the plane containing the pair of axes. Therefore , by pressing the pair of rollers against the skin surface so that the handle is along the skin surface, the plane including the pair of axis lines is in an inclined state with respect to the skin surface. Then, by moving the beauty device while maintaining this state, it is possible to deform the portion for which the beauty effect is desired so as to be picked up by a pair of rollers. As a result, a more excellent beauty effect can be expected by using the above-mentioned beauty device.

Further, the above-mentioned action of picking up the skin changes depending on the distance between the pair of rollers, and by keeping the distance between the pair of rollers within an appropriate range, the above-mentioned action can be surely experienced. Therefore, when the handle is tilted with respect to the plane including the pair of axes, by further providing the opening / closing restricting means, the above action can be surely experienced, and by extension, a more excellent beauty effect. Can be expected.

Further, the roller may have a substantially spherical shape. In this case, the pressing force of the rollers is likely to be concentrated on the portion sandwiched between the pair of rollers, so that the pressing force that can be felt can be sufficiently increased, and a more excellent beauty effect can be expected. Further, in this case, the operation of rotating the pair of rollers while pressing them against the skin can be performed more smoothly, and the ease of handling of the beauty device can be further improved.

The substantially spherical shape described above includes a true sphere and a shape in which the true sphere is distorted to the extent that it is recognized as a sphere as a general sensation such as a spheroid or a teardrop shape. Further, the roller may have a surface composed of a smooth curved surface, and may be a polyhedron having a surface composed of, for example, a large number of triangles or quadrangles. When the roller is a polyhedron, the surface of the roller 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 beauty effect can be expected.

Further, for the urging means, for example, a spring member, rubber, or the like can be used. Of these, it is preferable to use a metal spring member as the urging means. The metal spring member tends to increase the urging force moderately. Therefore, a better beauty effect can be expected by using the above-mentioned beauty device.

Further, the handle may have a solar cell panel, and may be configured so that an electric current can be passed through the human body skin in contact with the roller by the electromotive force of the solar cell panel. In this case, the current flowing through the human skin activates the skin cells, which may have effects such as improving lymphatic flow, promoting blood circulation, and improving metabolism. As a result, a more excellent beauty effect can be expected by using the above-mentioned beauty device.

The tubular member 341 is made of an elastomer and has opening ends 343 at both ends in the lateral direction as shown in FIGS. 5 and 7. The rear end of the sub-handle portion 33 is inserted into each open end portion 343. Further, the in-cylinder space 342 of the tubular member 341 communicates with the spring accommodating space 35 in a state of being assembled to the sub-handle portion 33.

The regulation plate 71 is arranged along a substantially U-shape at the rear end of the handle 3. As shown in FIGS. 2 and 8, the regulation plate 71 is a metal having a base portion 712 passing through the tubular member 341 and an arm portion 713 extending from the base portion 712 toward each sub-handle portion 33. It is composed of boards. As shown in FIG. 8, the arm portion 713 has a substantially square pin insertion hole 711 at the front end portion, and also has a boss insertion hole 714 on the base 712 side (rear) of the pin insertion hole 711. ..

As shown in FIGS. 6 and 8, a regulation pin 72 made of metal is arranged through the pin insertion hole 711. As shown in FIG. 6, the regulation pin 72 is formed in a columnar shape having an outer diameter smaller than that of the pin insertion hole 711. Further, the vertical end of the regulation pin 72 is fixed to the base portion 331 and the case portion 334. Therefore, the position of the regulation pin 72 is changed according to the opening / closing operation of the handle 3 within the range in which the pin insertion hole 711 is open (FIG. 8, arrow 101).

Further, as shown in FIG. 7, a boss 336 erected in the case portion 334 is inserted into the boss insertion hole 714. Therefore, the regulation plate 71 is held in a fixed position with respect to the boss 336. Further, when the handle 3 is opened and closed, the sub handle portion 33 rotates about 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 in a substantially U shape, and has a spring accommodating space 35 of the sub-handle portion 33 and a tubular member 341. It is arranged so as to pass through both the in-cylinder space 342. Further, the spring member 51 is deformed as the handle 3 is opened and closed, and when the spring member 51 is deformed, the spring member 51 is urged to return to the natural state and presses the wall surface of the spring accommodating space 35. As a result, the urging force of the spring member 51 is transmitted to the pair of rollers 4 via the sub-handle portion 33.

Next, the operation of the opening / closing regulating means of the beauty device 1 of this example will be described together with the method of using the beauty device 1. When using the beauty device 1, the user grips the grip portion 32 so that light is incident on the solar cell panel 6 while bringing the case portion 334 of the sub handle portion 33 into contact with the palm of the hand. Then, as shown in FIG. 3, the pair of rollers 4 are 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 axis lines A is inclined with respect to the skin surface 8.

By further increasing the force for 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 opens against the urging force of the spring member 51 (FIG. 8, arrow). 102), the distance d between the pair of rollers 4 can be expanded (FIG. 4, arrow 100). The pair of shaft portions 2 in the beauty device 1 of this example are in a state in which the distance d between the pair of rollers 4 is changed from the natural state and in a natural state, as the distance d from the base portion on the handle 3 side toward the tip side. It is configured to maintain an expanded state in which the distance between the pair of axis lines A is widened. That is, the beauty device 1 of this example is configured to be in an expanded state at all times.

At this time, the regulation plate 71 and the regulation pin 72 function as opening / closing restricting means as follows. Inside the sub-handle portion 33, the regulation pin 72 fixed to the base portion 331 and the case portion 334 moves outward in the lateral direction as the handle 3 opens from the natural state (FIG. 8, arrow 102). FIG. 8, arrow 101). Then, when the regulation pin 72 comes into contact with the edge of the pin insertion hole 711, the handle 3 cannot be opened any more.

The regulation plate 71 and the regulation pin 72 in the beauty device 1 of this example 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. .. On the other hand, in the beauty device 1 of this example, the base portion 331 is made of ABS resin. Therefore, by increasing the force of pressing the pair of rollers 4 against the skin surface 8, the sub-handle portion 33 can be elastically deformed to widen the distance d between the pair of rollers 4 beyond the above-mentioned specific range. In the beauty device 1 of this example, practically, the maximum value of the distance d between the pair of rollers 4 when the sub-handle portion 33 is elastically deformed is 65 mm.

With the pair of rollers 4 in contact with the skin surface 8, the beauty device 1 is moved in the direction from the roller 4 side to the handle 3 side to obtain a beauty effect as shown in FIGS. 3 and 4. The portion 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, by moving the beauty device 1 and applying a force in the direction of closing the handle 3, the pressing force applied to the portion sandwiched between the pair of rollers 4 can be increased.

Further, while the roller 4 is in contact with the skin surface 8 and the case 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 case portion 334 and the human body is formed. To. Therefore, the electromotive force of the solar cell panel 6 allows an electric current to flow through the human skin in contact with the roller 4.

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

The beauty device 1 has a pair of rollers 4 configured so that the distance d between them can be changed, and a spring member 51 as an urging means 5. Therefore, the beauty device 1 can be suitably used from a relatively large undulating portion such as the face and arms to a relatively small undulating portion such as the abdomen.

Further, in the beauty device 1, when the distance d between the pair of rollers 4 is widened, the urging force by the urging means 5 acts on each roller 4, and the pair of rollers 4 are urged in a direction approaching 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 eventually, beauty effects such as beautifying the skin can be expected.

Further, the beauty device 1 has a regulation plate 71 and a regulation pin 72 as opening / closing regulation means. Therefore, the beauty device 1 can surely prevent the distance d between the pair of rollers 4 from becoming excessively wide, and can surely prevent the beauty device 1 from being damaged.

Further, 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 shaft lines A increases from the base portion on the handle 3 side toward the tip end side. That is, the beauty device 1 becomes easier to handle for the user by realizing the expanded state in the natural state. Further, by realizing the expanded state in a state where the distance d between the pair of rollers 4 is changed from the natural state, the pressing force felt in the portion sandwiched between the pair of rollers 4 can be appropriately increased. , You can expect a better beauty effect.

Further, the handle 3 has a pair of sub-handle portions 33 that support the shaft portions 2, and a connecting portion 34 that connects the pair of sub-handle portions 33. A pair of shaft portions 2 and a connecting portion 34 are provided at ends of the sub-handle portion 33 on opposite sides to each other. 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 where the beauty effect is desired. As a result, the ease of handling of the beauty device 1 can be further improved, and a more excellent beauty effect can be expected.

Further, the handle 3 is tilted with respect to a plane P including a pair of axis lines A. Further, in this example, the regulation plate 71 and the regulation pin 72 are designed so that the distance d between the pair of rollers 4 can be changed in the 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 above-mentioned action of picking up the skin can be surely experienced. As a result, a better beauty effect can be expected.

Further, the roller 4 has a substantially spherical shape. Therefore, the pressing force of the roller 4 tends to be concentrated, and the pressing force experienced by the user tends to be sufficiently large. In addition, the operation of rotating the pair of rollers 4 while pressing them against the skin can be performed more smoothly, and the ease of handling of the beauty device 1 can be further improved.

Further, the handle 3 has a solar cell panel 6, and is configured so that an electric current can flow through the human skin in contact with the roller 4 by the electromotive force of the solar cell panel 6. Therefore, a more excellent beauty effect can be expected by using the beauty device 1.

Further, in this example, since the solar cell panel 6, the roller 4, and the case portion 334 provided on the same sub-handle portion 33 are connected to each other, each sub-handle portion 33 has a closed circuit including human skin. Can be formed. As a result, it is possible to prevent poor contact between the roller 4 and the case portion 334 and the human skin. Therefore, the beauty device 1 can be expected to have a more excellent beauty effect.

Further, since the sub-handle portion 33 of this example has a substantially elliptical cross section in the front-rear direction, it has high rigidity structurally. The sub-handle portion 33 is reinforced by a regulation plate 71 made of a metal plate, and has higher rigidity than the case where the regulation plate 71 is not provided. By providing these configurations, the beauty device 1 can sufficiently increase the pressing force applied to the portion where the beauty effect is desired by the pair of rollers 4 even when the sub-handle portion 33 is elastically deformed.

If the rigidity of the sub-handle portion 33 is excessively low, the sub-handle portion 33 may bend when the portion for which the beauty effect is desired is pressed by the pair of rollers 4. Therefore, in some cases, even if the handle 3 is opened and closed, the distance d between the pair of rollers 4 is not sufficiently narrowed, and the pressing force applied to the portion where the beauty effect is desired may not be sufficiently felt. On the other hand, the beauty device 1 of this example can avoid such a problem by having the above configuration, and can sufficiently increase the pressing force applied to the portion where the beauty effect is desired by the opening / closing operation of the handle 3. As a result of the above, the beauty device 1 can sufficiently increase the pressing force that can be felt, and a more excellent beauty effect can be expected.

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

(Example 2)
This example is an example of the beauty device 1 having the sub-handle portion 36 having increased rigidity while reducing the number of parts. Although not shown in the figure, the outer shape of the beauty device 1 of this example is the same as that of the first embodiment.

As shown in FIG. 9, the sub-handle portion 36 is composed of three parts, a base portion 361, a spring accommodating portion 362, and a case portion 363. The spring accommodating portion 362 and the case portion 363 are arranged in the latter half of the base portion 361, and are fastened to the base portion 361 by screws (not shown). In FIG. 9, for convenience, the description of the roller 4, the regulation pin 72, the screw, and the like is omitted.

As shown in FIGS. 9 and 10, the base portion 361 has a rib 364 for increasing the rigidity at a portion where the spring accommodating portion 362 is overlapped. As a result, the rigidity of the base portion 361 itself can be increased, and by extension, the rigidity of the sub handle portion 36 can be further increased.

The spring accommodating space 35 in which the spring member 51 is accommodated is formed between the base portion 361 and the spring accommodating portion 362. As shown in FIG. 11, 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.

Further, in this example, as shown in FIG. 11, a regulation convex portion 365 functioning as an opening / closing restricting means is provided at the rear end of the spring accommodating portion 362, that is, a portion facing each other while being inserted into the connecting portion 34. It is provided.

The regulation convex portion 365 is configured such that the top portions 366 provided at substantially the central portion in the front-rear direction abut against each other in a natural state. Further, the regulation convex portion 365 has an inclined surface 367 (367a, 376b) that recedes outward in the lateral direction from the top portion 366 toward the front-rear direction. The inclined surfaces 367a and 367b are arranged so as to be separated from each other in a natural state as shown in FIG.

The regulation convex portion 365 configured in this way functions as an opening / closing restricting means as follows. That is, when the handle 3 is opened, the pair of sub-handle portions 36 rotate around the boss 368 inserted into the boss insertion hole 714 (not shown) of the regulation plate 71 (FIG. 11, arrow 103). At this time, as the sub-handle portion 36 rotates, the inclined surfaces 367a on the rear side of the regulation convex portion 365 come close to each other, and the inclined surfaces 367a come into contact with each other. Then, the handle 3 cannot be opened any more, limited to the state in which the inclined surfaces 367a on the rear side are in contact with each other as shown in FIG. In this way, the opening / closing operation of the handle 3 is regulated with the position where the inclined surfaces 367a come into contact with each other as the upper limit, so that the upper limit of the changeable range of the distance d between the pair of rollers 4 is regulated.

In this example, the lower limit when closing the handle 3 is regulated by the inclined surface 367b on the front side of the regulation convex portion 365. That is, as described above, when the handle 3 is closed, the sub-handle portion 36 rotates and the inclined surfaces 367b on the front side approach each other. Then, when the operation of closing the handle 3 is continued, the inclined surfaces 367b come into contact with each other, and the handle 3 cannot be closed any more, limited to the state in which the inclined surfaces 367b on the front side are in contact with each other. In this way, the opening / closing operation of the handle 3 is regulated with the position where the inclined surfaces 367b come into contact with each other as the lower limit, so that the lower limit of the changeable range of the distance d between the pair of rollers 4 is regulated.

Further, although not shown in the figure, in this example, the length of the arm portion 713 of the regulation plate 71 is about three times longer than that of the first embodiment. By lengthening the arm portion 713, the rigidity of the sub-handle portion 36 can be further increased.

Others are the same as in Example 1. Of the codes used in FIGS. 9 to 12, the same codes as those used in the first embodiment show the same components and the like as those in the first embodiment unless otherwise specified.

As in this example, the rigidity of the sub-handle portion 36 can be further increased by using the base portion 361 having the rib 364 for the sub-handle portion 36 and making the arm portion 713 of the regulation plate 71 longer.

In addition, in Example 1 and Example 2, the configuration using the regulation plate 71 and the regulation pin 72 as the opening / closing regulating means and the configuration in which the regulation convex portion 365 is provided on the sub handle portion 36 have been described, but other than this. It is also possible to adopt the configuration of. For example, by connecting the pair of sub-handle portions 36 with a chain or the like, there is a configuration in which the openable / closable range of the pair of sub-handle portions 36 is restricted within the range in which the chain extends.
