The handle cover is divided into upper and lower parts. The handle is assembled by combining the upper and lower handle covers so as to surround the base body.

Japanese Unexamined Patent Publication No. 2013-103085

The base body is formed along the inner surface of the handle cover. Therefore, when the user operates the beauty device while holding the handle, the base body and the handle cover may rub against each other. At that time, there was a concern that if the resin members rub against each other in a surface-to-face contact state, an unpleasant squeaking noise would be transmitted to the user.

The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a beauty device capable of avoiding the generation of squeaking noise of a handle.

The beauty device of the present invention is provided with a rotating body rotatably, and has a handle base provided inside the handle of the beauty device and a handle cover having a surface facing the handle base and covering the handle base. , a plurality of protrusions disposed on said handle cover the handle base Neu deviation or the other of the opposed surfaces, and and a plurality of ribs small projection height than the protrusions, the handle base the It has compatible surfaces facing each other along the inner surface of the handle cover, and the plurality of protrusions are arranged on either the compatible surface or the inner surface of the handle cover, and hit the facing surfaces on the other side in a normal state. The plurality of ribs are in contact with each other, and the plurality of ribs are arranged on the surface of the conforming surface and the inner surface of the handle cover on which the plurality of protrusions are arranged, and are not separated from the facing surface on the other side in a normal state. It is characterized by being in a contact state.

The cosmetological device of the present invention can impart a cosmetic effect by the user holding the handle portion and rotating the rotating body while pressing the rotating body against the body.

By the way, in the past, the handle cover and the handle base may locally strongly come into contact with each other during use to generate a squeaking noise, but in the present invention, the handle cover and the handle cover are provided on at least one of them. The protrusion is in contact with or close to the mating side so that a gap can be secured between the handle base and the handle cover.
In the present invention, the protrusion may be in constant contact with the other side, or may be in contact with the other side when necessary, although it is normally non-contact. Further, in any of the above cases, the squeaking noise suppressing function is slightly different depending on whether the protrusion is formed of a soft material or a hard material.
Hereinafter, when the protrusion is formed of a soft material and is not normally in contact with the mating side, when the protrusion comes into contact with the mating side, the protrusion is deformed to apply stress at the time of contact. Absorbs and suppresses the generation of squeaking noise. When the protrusion is made of a soft material and is in constant contact with the mating side, the protrusion is also slightly deformed by the slight movement of the mating side, thereby reducing the stress at the time of contact. Absorbs and suppresses the generation of squeaking noise.
On the other hand, when the protrusion is made of a hard material and is normally in non-contact with the mating side, the protrusion narrows the gap between the mating side, so that the protrusion immediately contacts the mating member when necessary. By suppressing the movement, the generation of squeaking noise is suppressed. When the protrusion is made of a hard material and is always in contact with the mating side, the protrusion completely fills the gap with the mating side, so that the relative movement of the mating member is always suppressed. Suppresses squeaking noise.
As a result, the handle cover and the handle base do not come into contact with each other, and the position of the handle cover and the handle base is fixed by the contact of the protrusions, so that the situation where squeaking noise is generated can be avoided or reduced. Can be done.

The tip of the handle H is a bifurcated branch portion D that branches and extends. A pair of rotating bodies 1 are attached to the tips of both branch portions D at intervals.

As shown in FIG. 2 and the like, the handle H has a built-in handle base 2 made of synthetic resin. The handle base 2 is covered so as to be wrapped by handle covers 3 and 4 which are paired up and down and can be combined with each other. The upper and lower handle covers 3 and 4 are both made of synthetic resin material, and both the front and back surfaces are plated with conductive metal.

FIG. 3 shows the entire handle base 2, and is a plan view of both handle covers 3 and 4 as viewed from the side facing the upper handle cover 3. As shown in FIG. 3, the handle base 2 is formed mainly of the base portion 6, and a pair of bearing cylinder portions 5 which are internal structures of the branch portion D are bifurcated and formed at the tip portion thereof.

The base portion 6 is formed so that the central portion in the longitudinal direction is the widest in the plan view and the width gradually narrows toward both ends in the longitudinal direction, and the end portion opposite to the bearing cylinder portion 5 side has a sharp shape. Is formed in.

The base 6 of the handle base 2 is formed in a bottomed shallow bowl shape with the side facing the lower handle cover 4 as the bottom surface and opening to the upper handle cover 3 side. That is, the bottom surface of the base portion 6 is a conforming surface 7 formed along the inner surface of the lower handle cover 4. The compatible surface 7 of the base portion 6 is formed so as to gradually rise toward the peripheral edge portion with an arcuate curved surface (see FIG. 5). Further, as shown in FIG. 2, the base 6 is formed in a bow shape in a side view. Specifically, the conforming surface 7 of the base 6 is formed so as to form a curved surface that is convex toward the lower handle cover 4 side.

As shown in FIGS. 2 and 4, a part of both bearing cylinders 5 and the end portion on the opposite side in the longitudinal direction on the conforming surface 7 of the base 6 is thinned, and is hooked on the rising wall of the thinned portion. The claw 8 is formed. As shown in FIG. 2, the hook claw 8 can be locked with the receiving edge 9 formed at the corresponding position of the lower handle cover 4.

As shown in FIG. 4, mounting holes 10A to 10C for screwing the handle base 2 and the upper handle cover 3 are arranged in parallel at three places on the central axis in the width direction of the handle base 2. However, each is formed through. In this reference example 1, the positions where the mounting holes 10A to 10C are provided are the positions of the central portion in the longitudinal direction of the base portion 6, the portion near the hook claw 8, and the intersection of the central axes of both bearing cylinder portions 5. It is in the vicinity of. As shown in FIG. 2, in each of the mounting holes 10A to 10C, the boss portions 11A to 11C are coaxially projected toward the opening surface side of the base portion 6. However, the boss portion 11A of the mounting hole 10A located on the bearing cylinder portion 5 side is formed shorter than the other boss portions 11B and 11C. Each boss portion 11A to 11C is formed in a cylindrical shape that opens to the lower handle cover 4 side, and a seat surface 12A to 12C is formed at the protruding end portion thereof.

As shown in FIG. 2, screw-in cylinder portions 13A to 13C are provided so as to project from each portion coaxially corresponding to each boss portion 11A to 11C in the upper handle cover 3. The protruding end portions of the screw-in cylinder portions 13A to 13C are abutted against the seat surfaces of the boss portions 11A to 11C. In that state, a screw with packing (14: tapping screw) is inserted from each boss portion 11A to 11C side so as to be screwed into the screw-in cylinder portion 13A to 13C side, thereby the handle base 2 and the upper handle cover. The connection with 3 and the water stoppage at each of the boss portions 11A to 11C of the handle base 2 are performed.

As shown in FIG. 2, a weight 15 is attached between the boss portion 11B in the central portion in the longitudinal direction and the boss portion 11C on the end portion side inside the base portion 6. A support surface 16 for supporting the weight 15 is provided on the inner surface side of the base portion 6. On the inner surface of the base portion 6, on the central axis connecting the boss portion 11B in the central portion in the longitudinal direction and the boss portion 11C on the end side, the first and second insertion shafts for positioning and fixing to the weight 15 are performed. The portions 17A and 17B are formed so as to protrude. The weight 15 is formed in a rectangular parallelepiped shape made of metal, and both insertion shaft portions 17A and 17B are penetrated therein. Of the two insertion shaft portions 17A and 17B, the first insertion shaft portion 17A arranged closer to the center in the longitudinal direction is formed in a hollow shape in which the protruding end side opens. A fixing screw 19 (conductive metal tapping screw) is screwed into the first insertion shaft portion 17A from the upper surface side of the weight 15 via a metal washer subjected to conductive plating. The second insertion shaft portion 17B arranged on the end side in the longitudinal direction has a smaller diameter than the first insertion shaft portion 17A, but is formed longer than the first insertion shaft portion 17A. The second insertion shaft portion 17B has a tip end portion abutted against a receiving seat 20 formed on the upper handle cover 3 in a state where the handle H is assembled. By providing the weight 15, the center of gravity is closer to the center side of the handle H, which makes it easier to hold.

As shown in FIG. 3, on the inside of the base portion 6, a support frame 22 for supporting the solar cell panel 21 is formed so as to project in a region closer to the bearing cylinder portion 5 side than the central portion in the longitudinal direction. The solar cell panel 21 is formed in a substantially rectangular shape and a thin plate shape. The support frame 22 is composed of a frame wall that surrounds the solar cell panel 21 from three sides. The solar cell panel 21 is housed inside the support frame 22 and is supported by the upper edge of each frame wall. As shown in FIG. 2, in a state where the solar cell panel 21 is supported, the upper surface of the panel 21 is slightly lower than the upper surface of the support frame 22 (see FIG. 5).

As shown in FIG. 2 and the like, in the upper handle cover 3, a window hole 23 is formed at a portion corresponding to the solar cell panel 21. A lens member 24 made of a translucent material is fitted in the window hole 23. A flange edge 25 is formed overhanging along the peripheral edge of the lens member 24 on the side facing the solar cell panel 21, and is formed on the opening edge of the window hole 23 when the lens member 24 is attached. The lens member 24 is attached to the upper handle cover 3 in a sealed state by a seal ring 27 fitted around the flange edge 25 while being abutted against the locking step edge 26.

Further, as shown in FIG. 2, in a state where the upper and lower handle covers 3 and 4 are combined, the inner surface of the lens member 24 is in contact with the upper edge of the support frame 22. As a result, the solar cell panel 21 is mounted using the lens member 24 without the need for a dedicated member for fixing itself.

A ring-shaped terminal 29 is attached to the positive electrode of the solar cell panel 21 via a lead wire 28. This terminal 29 is interposed between the seat surface 12B of the boss portion 11B located at the center of the handle base 2 in the longitudinal direction and the screw-in cylinder portion 13B of the upper handle cover 3, and is conducted by being inserted into the fixing screw 14. The connection is made in the state. As a result, the positive electrode of the solar cell panel 21 is electrically connected to the upper and lower handle covers 3 and 4 by pressing the ring-shaped terminal 29 and the screw-in cylinder portion 13B with the fixing screw 14. Become. Further, instead of the lead wire 28 and the ring-shaped terminal 29, a metal plate extending from the solar cell panel 21 may be used for connection. In this case, using a metal plate that is more rigid than the lead wire contributes to fixing the solar cell panel 21. Further, the ring-shaped terminal 29 may have a shape other than the ring shape (for example, a C-shape) as long as it can be pressure-contacted with the screw-in cylinder portion 13B.

As shown in FIG. 7, two lead wires 45 are led out from the negative electrode of the solar cell panel 21, and a ring-shaped terminal 46 is connected to each terminal. Both terminals 46 are electrically connected to both rotating shafts 31 of the rotating body 1 described later, and as a result, the rotating body 1 is electrically connected to the negative electrode. This point will be described later.

Next, the support structure of the rotating body 1 will be described. As shown in FIG. 3, in the branch portion D of the handle H, as described above, the handle base 2 is provided with a pair of bearing cylinder portions 5 in a bifurcated shape. Both bearing cylinders 5 are formed coaxially with the central axis of the branch D. Both bearing cylinders 5 are formed in a cylindrical shape penetrating along the axis. A pair of split cylinders 3A and 4A that can surround the bearing cylinder 5 of the handle base 2 by half a circumference are formed on both the upper and lower handle covers 3 and 4 sides. As shown in FIG. 6, in a state where the upper and lower handle covers 3 and 4 are united, the corresponding split cylinder portions 3A and 4A surround the bearing cylinder portion 5 of the handle base 2 in a substantially close contact state along the entire circumference. .. As shown in FIG. 6, for the boss portion 11A provided near the position where the central axes of both bearing cylinder portions 5 intersect, the upper handle cover 3 is the same as for the other boss portions 11B and 11C. The screw 14 is tightened with respect to the screw-in cylinder portion 13A of the above.

As shown in FIG. 6, in a state where both bearing cylinders 5 of the handle base 2 are combined while surrounding the divided cylinders 3A and 4A of the upper and lower handle covers 3 and 4, the tips of the divided cylinders 3A and 4A are combined. A handle cap 30 made of an insulating material (made of synthetic resin) is fitted on the outer periphery. The handle cap 30 is capable of inserting a large diameter portion of the rotating shaft 31, and is fitted to the outer periphery of the split cylinder portions 3A and 4A in the butt state, so that the split cylinder portions 3A and 4A are tightened and rotated. The rattling of the shaft 31 is regulated. As shown in FIG. 6, the handle cap 30 is interposed between the handle covers 3 and 4 and the rotating body 1 described later, and a predetermined distance can be secured between the two. As a result, a state in which electrical insulation is ensured between the split cylinder portions 3A and 4A of the handle covers 3 and 4 and the rotating body 1 is ensured.

As shown in FIG. 6, on the protruding end side of both bearing cylinders 5, rotating shafts 31 for rotatably supporting the rotating body 1 are provided coaxially with each other. The rotating shaft 31 is made of metal, and the surface thereof is plated with a conductive material. A large-diameter flange portion 31A is integrally overhanging and formed near the end portion of the rotating shaft 31 on the bearing cylinder portion 5 side. The end side of the rotating shaft 31 is inserted into the bearing cylinder portion 5 via the seal ring 32, and the flange portion 31A is in a state of being abutted against the end surface of the bearing cylinder portion 5. A set screw 33 with a washer is screwed into the end of the rotating shaft 31 from the opposite end of the bearing cylinder 5. The set screw 33 is plated with a conductive material. Further, the terminal 46 connected to the negative electrode of the solar cell panel 21 is connected to the double set screw 33.

The two rotating bodies 1 are the core body 34 made of synthetic resin and formed into a substantially spherical shape, the core cap 35 made of conductive resin fitted to the tip of the core body 34, and the core body 34 and the core cap. The outer periphery of the 35 is provided with a coating-molded outer cover 36. The outer cover 36 is made of synthetic resin, and the entire inner and outer surfaces are plated with conductive metal.
The core cap 35 is formed with a curved conduction surface 35A so as to be closely fitted to the inner surface of the apex portion of the rotating body 1, and a housing cylinder portion 35B is projected from the inner peripheral edge portion.

As shown in FIG. 6, a shaft hole 37 penetrates the core body 34 along the central axis, and the rotating shaft 31 and the handle cap 30 portion are housed inside. A locking ridge 38 is formed so as to project inward along the circumferential direction at the substantially central portion of the shaft hole 37 in the core body 34 in the axial direction. A bearing member 39 is provided on the rotating shaft 31. The bearing member 39 is rotatable around the rotating shaft 31.
As shown in FIG. 7, a flange portion 39A is formed overhanging at the shaft end of the bearing member 39, and a pair of locking claws 39B are provided on the shaft portion of the bearing member 39. Both locking claws 39B are formed so as to protrude from the shaft portion in a natural state, and in the process of inserting the bearing member 39 into the locking ridge 38, both locking claws 39B are formed on the inner peripheral surface of the locking ridge 38. When both locking claws 39B pass through the locking ridge 38, they are elastically restored and locked to the locking ridge 38. As a result, the bearing member 39 is prevented from coming off by sandwiching the locking ridge 38 between the flange portion 39A and the locking claw 39B, and as a result, the rotating body 1 is in a fixed state.
The bearing member 39 is made of a conductive resin material. As a result, the negative electrode of the solar panel 21 is electrically applied to the outer cover 36 of the rotating body 1 via the lead wire 45, the terminal 46, the set screw 33, the bearing member 39, and the inner surface of the rotating body 1 in contact with the bearing member 39. Will be connected to.

The bearing member 39 is fitted inside the core cap 35 and penetrates the end portion of the rotating shaft 31 in a close contact state. A retaining ring 18 is fitted to the shaft end of the rotating shaft 31.

Next, the countermeasure structure for squeaking noise will be described. First, a waterproof structure between the open side of the handle base 2 and the upper handle cover 3 will be described. As shown in FIG. 3, a seal edge 41 is formed so as to project from the opening edge (periphery on the side facing the upper handle cover 3) of the handle base 2. The seal edge 41 is provided on the entire peripheral edge of the base 6 and the portion of both bearing cylinders 5 that is open to the upper handle cover 3 side, and is continuous over the range facing the entire peripheral edge of the upper handle cover 3. Is formed.
The seal edge 41 is formed of a soft rubber material that is softer than the handle base 2 and the upper and lower handle covers 3 and 4. In this reference example 1, when the handle base 2 is molded in two colors, it is molded at the same time. Then, in the primary side mold for two-color molding, the main portion (the portion molded of synthetic resin) of the handle base 2 is formed, and the seal edge 41 is formed by the secondary side mold (none of which is shown). And each protrusion 42 described later is formed at the same time.
As shown in FIG. 4, each protrusion 42 is projected onto the compatible surface 7 of the handle base 2. That is, each protrusion 42 projects on the surface of the handle base 2 facing the lower handle cover 4. As a result, as shown in FIGS. 5 and 6, when the lower handle cover 4 is attached, the protrusions 42 normally contact the lower handle cover 4 and come into contact with the lower handle cover 4. It functions as a spacer to secure a predetermined gap between the two.
The arrangement state of each protrusion 42 is as shown in FIG. Specifically, there are a total of four locations in the region between the mounting hole 10B located in the central portion in the longitudinal direction, the mounting hole located closer to the hook claw 8 and 10C (hereinafter referred to as the lower region). .. These are arranged symmetrically and side by side in the longitudinal direction, two on each side with the central axis along the longitudinal direction as a boundary. Further, a total of four protrusions 42 are arranged in a region (hereinafter, referred to as an upper region) between the mounting holes 10A located between the bearing cylinders 5 and the mounting holes 10B in the central portion in the longitudinal direction. One of these is arranged on each side of the longitudinal direction on the central axis, and two are arranged symmetrically in the width direction between them at positions sandwiching the central axis. Of these, two sandwiching the central axis in the width direction are arranged in the middle of the frame walls facing each other in the longitudinal direction in the support frame 22, and two located on the central axis are the support frame 22. It is arranged almost inside. Further, in Reference Example 1, in the region (branch region) where both bearing cylinder portions 5 are provided, one is arranged on each central axis with the boss portion 11A sandwiched in the width direction.

At the time of molding by the primary side mold described above, a circular through hole 43 is formed in each of the portions where the protrusions 42 are arranged. When the protrusion 42 is molded by the secondary mold, the molded meat is formed so as to protrude from the compatible surface 7 by flowing from the inside of the base 6 toward the compatible surface 7, and any of the protrusions. The 42 is also connected to and integrated with the seal edge 41 via the connecting portion 44 on the inside of the handle base 2 (on the side opposite to the compatible surface 7).

As shown in FIG. 3, each protrusion 42 belonging to the lower region is individually connected to the seal edge 41 via the connecting portion 44, and the protrusions 42 are not connected to each other. On the other hand, the protrusions 42 belonging to the upper region are connected to each other by the connecting portion 44. However, only the protrusion 42 located across the central axis is connected to the seal edge 41 via the connecting portion 44. The remaining two are not connected to the seal edge 41. The two protrusions 42 in the bifurcation region are individually connected to the seal edge 41 via the connecting portion 44.

Next, the action and effect of the present reference example 1 configured as described above will be described. When using the beauty device B, if the handle is grasped and the rotating body 1 is applied to the skin such as the face to roll, the skin and its lower tissues are stimulated and the blood circulation is improved. Is demonstrated. Further, at this time, since the energizing circuit of the solar cell panel 21 is composed of the handle, the rotating body 1, and the human body of the user, a weak current flows through the body of the user to electrically stimulate the cells of the body and activate the cells. The beauty effect is further enhanced by the conversion.

The beauty device B of this reference example is assembled by surrounding the handle base 2 with the upper and lower handle covers 3 and 4 and combining them. At that time, each protrusion 42 has a predetermined distance between the handle base 2 and the lower handle cover 4. Therefore, even if the distance between the handle base 2 and the lower handle cover 4 is narrower than the setting due to variations in manufacturing or assembly, the handle base 2 and the lower handle are used while the beauty device B is being used. The cover 4 does not come into contact with each other and rub against each other. Therefore, it is possible to avoid the generation of squeaking noise that is unpleasant for the user. That is, since the protrusion 42 of this reference example is in contact with the lower handle cover 4 from normal times, the protrusion 42 is affected by a force that causes the protrusion 42 to move slightly with respect to the lower handle cover. By deforming, it absorbs stress and suppresses the generation of squeaking noise.

Further, in Reference Example 1, a protrusion 42 is also arranged at the branch portion of the beauty device B. In particular, since the split cylinder portions 3A and 4A of the upper and lower handle covers 3 and 4 are fastened to each other by the handle cap 30, there is a concern that the lower handle cover 4 and the handle base 2 may come into contact with each other at the branch portion D. However, in order to secure a distance between the bearing cylinder portion 5 of the handle base 2 and the lower handle cover 4 regardless of the tightening by the handle cap 30, the protrusion 42 arranged at the branch portion is used at the portion. It also effectively responds to squeaking noises.

Further, the space between the handle base 2 and the upper handle cover 3 is in a watertight state by the seal edge 41. Therefore, even if the solar cell panel 21 is housed in the handle H, the function retention of the panel 21 can be reliably achieved. Further, in this reference example, the lens member 24 comes into contact with the upper edge of the support frame 22 to mount the solar cell panel 21, so that the number of parts can be reduced and beauty can be achieved because a dedicated fixing means is not required. The configuration of the entire vessel B can be simplified.

Further, in the present reference example 1, since each protrusion 42 is connected to the seal edge 41 via the connecting portion 44, the strength is higher than that in the case of forming each protrusion 42 without having a connecting relationship, and the position is high. It is difficult for slippage and defects to occur. Further, since the protrusions 42 are also connected to each other within a certain range, it is more effective against misalignment, defects, and the like.

Furthermore, in Reference Example 1, each protrusion 42 is formed through a through hole 43. Therefore, the strength of each protrusion 42 is increased by the molded meat extending in the through hole 43. Therefore, the support strength is higher than that in the case where the through hole 43 is not formed and the protrusion is formed as it is from the compatible surface 7, which is also effective in eliminating defects and the like.

Further, in Reference Example 1, a core cap 35 is provided at the shaft end of the rotating shaft 31, and the structure is such that a hole is not opened on the axis of the rotating shaft 31 at the apex of the rotating body 1. Therefore, almost the entire surface of the rotating body 1 including the apex can be widely used. Therefore, even if the apex is pressed against the user's skin, the user will not be hurt.

<Example 1 >
8 to 10 show Example 1 of the present invention. The main differences from Reference Example 1 are the addition of a squeak noise countermeasure structure to the handle base 50 and the arrangement of the protrusions 52. That is, as shown in FIG. 8, a total of five ribs 53 are integrally projected on the compatible surface 51 of the handle base 50. That is, each rib 53, which is also a protrusion of the present invention, is formed of a hard material. The ribs 53 are arranged along the substantially longitudinal direction of the handle base 50 in the bottom view and at appropriate intervals in the width direction.

Further, the protrusion 52 is different from Reference Example 1 except for the arrangement in the branch region. As shown in FIG. 8, the lower region is provided at only two locations with the central axis along the longitudinal direction as a boundary. Both protrusions 42 arranged here are arranged on the formation line of the rib 53.

In the upper region, two locations are arranged with the central axis as a boundary in the vicinity of the mounting holes 10B arranged near the center in the longitudinal direction. These are arranged slightly outside the formation line of the rib 53 in the width direction. Further, in the upper region, a total of three places are further arranged near both bearing cylinders 5. All of these are arranged on the formation line of the rib 53.

As shown in FIG. 9, the protrusion height of each protrusion 52 is set to be larger than that of each rib 53. Therefore, in the normal state shown in FIG. 9, only the protrusions 52 are in contact with the lower handle cover 4, and the ribs 53 are separated from each other and are in a non-contact state. However, as shown in FIG. 10, when the amount of crushing of each protrusion 52 becomes large and the distance between the lower handle cover 4 and the handle base side is shortened to a certain distance, the rib 53 side also comes into contact with each other. There is. That is, since the rib 53 finally secures the distance between the lower handle cover 4 and the handle base 50, it is possible to reliably avoid the situation of surface contact. In the case of the first embodiment, when the rib 53 comes into contact with the lower handle cover 4, the synthetic resin materials come into contact with each other, but the contact state is not the conventional surface contact state, but the line contact state. No squeaking noise is generated.

Other configurations are the same as in Reference Example 1, it is possible to have it exhibit the same effects as in Reference Example 1. In particular, in the first embodiment, the rib 53 is normally in a non-contact state with the lower handle cover 4, and is in contact with the lower handle cover 4 when necessary. That is, the rib 53 narrows the gap between the rib 53 and the lower handle cover 4, and when necessary, immediately contacts the rib 53 to suppress the relative movement with respect to the lower handle cover, whereby the generation of squeaking noise can be suppressed. ..
