Abstract

PROBLEM TO BE SOLVED: To provide an ear cuff which improves wearability to an ear and improves simplification and aesthetics. SOLUTION: In an ear cuff, the distance (width) between the left and right side surfaces of an annular body is shorter than the distance between the inner peripheral surface 1a and the outer peripheral surface 1b of the annular body, whereby between the left and right side surfaces of the annular body. A wide flat bearing surface is formed, and a slit S for sandwiching a part of the ear is formed in a part of the annular body. As a result, by bending both ends of the slit S in opposite directions (twisting directions), the gaps between both ends of the slit S can be easily widened and mounted in the circumferential direction of the annular body and in the axial direction of the annular body. On the other hand, the spring force in the asymmetric direction can be maintained. Further, the annular direction and the side surface portion of the annular body become wider around the slit S of the ear cuff to improve the brilliant reflectivity. [Selection diagram] Fig. 1

Description

The present invention is intended to simplify the wearing of ear cuffs and prevent them from being accidentally dropped off, mainly for ear cuffs that are used by women for the purpose of fashionably improving their decorativeness by attaching them to their ears or the like.

Most of the earrings that have been widely used in the past have pierced holes in the earlobe, and various designed earrings are attached to the pierced holes. From a cosmetic point of view, it was almost impossible to attach earrings to the part, near the back of the head, or elsewhere. Also, depending on the shape and design of the earring attachment part (end), the existing pierced hole will not fit inside the hole, and even when multiple other earrings are stacked, the weight will be burdened on the ear itself. It is no longer meeting the demands of the times.

Therefore, recently, it is becoming common to attach the earrings to a desired position such as an earlobe by sandwiching the front and back of the ear with both ends of the earring ring without making a hole in the ear.
As an example, the first pad portion that comes into contact with the front side of the ear and the magnetic force on the back side of the ear are attached to both ends of the connecting ring portion that is formed in a substantially U shape so that the user's earlobe can be pinched by synthetic resin. A second pad part that comes into contact with the opposite position is provided, and a magnet part that attracts each other by magnetic force is attached to each of the two pad parts so that the earring can be attached to an arbitrary position of the earlobe. Is known (see Practical New Design Registration No. 3210329).

Further, the ends of the earring members are pivotally attached to each other by eyelet members so as to be rotatable with each other, and O-rings are used to secure the rotational resistance of both earring members on the free end-side facing peripheral contact surfaces of the earring members. A ring is interposed to form an opposed holding surface for holding the earlobe near the end of the earring member on the opposite side of the position where the eyelet member is provided, and one or both of the earring members of the decorative body. Some are provided with an attachment portion (see JP-A-2017-209301).

Further, it is composed of a first portion 60 straddling the earlobe via the second portion 70 and a lever 30, and a leaf spring 36 is attached to the lever, and the lever 30 is urged toward the pedestal 20 by the leaf spring. It is also known that the deterioration of the urging portion is less likely to occur by making the urging portion less likely to occur (see Utility Model Registration No. 3225270). Further, the ring body 2a and the sphere 2b are provided at both ends of a part of the ring-shaped earring body 1 so as to sandwich the earlobe, and the spring 3 for imparting elasticity to the earring body is attached so that the earlobe does not feel tired. Earrings that can be attached gently are also known (see Practical New Design Registration No. 3225308).

However, in the earring described in Patent Document 1, the first pad portion that abuts the front side of the ear at both ends of the connecting ring portion that is formed in a substantially U shape so that the user's earlobe can be sandwiched by the synthetic resin. And, by providing a second pad part that comes into contact with the back side of the ear and attaching a magnet part that attracts each other by magnetic force to each of both pad parts, the earring can be attached to any position of the earlobe. This has the advantage that the earrings can be fixed and held at any position on the earlobe without the need for piercing holes, but on the other hand, it is easy to match the magnetic action points on the front and back, and it is also easy to do. Since it is necessary to attach two magnets that sandwich the earlobe, the amount is slightly increased and the burden on the attachment part such as the earlobe increases, so it is not suitable for long-term wearability, and it looks good in terms of decoration. Has the drawback that it is not good.

Further, although the resin earrings described in Patent Document 2 have an advantage in that they can be attached to any position of the earlobe, the facing holding surfaces attached to both free ends are slightly too large and are not very good in appearance. There are drawbacks. Further, the earring described in Patent Document 3 has a slightly large structure because the urging portion 40 instead of the spring is attached to the portion of the earring that sandwiches the earlobe, and there is a slight problem in terms of decorativeness as the earring. ..
Further, in the earring described in Patent Document 4, a spherical first free portion 1a is attached to one end of both ends of the annular opening of the earring to be attached to an earlobe or the like, and the spherical first free portion 1a is attached to the other end of the earlobe. A fastener 2 is formed by a first free portion 1b provided with a ring body 2a that receives the ring body 2a.

In this case, the structure of the fastener 2 itself is simple and there is little risk of impairing the decorativeness, but in order to reduce the burden on the earlobe of the fastener 2, it is necessary to secure a urging force in the middle of the ring of the earring. Since it is necessary to attach the spring 3, there is a slight problem in terms of workability and decorativeness, and there is a drawback that the manufacturing cost is also high.

Therefore, the present invention has come up with an ear cuff that is the simplest as an earring, does not impair the decorativeness, is easy to wear when attached to an earlobe or an ear at an arbitrary position, and is not burdensome. .. Specifically, it is an annular ear cuff for attaching to an ear, and the annular ear cuff has a shorter distance (width) between the left and right side surfaces of the ring than the distance between the inner peripheral surface and the outer peripheral surface of the ring. As a result, the ear cuff is formed in a wide flat surface, and a slit for sandwiching a part of the ear is formed in a part of the annular ear cuff.

Further, in the present invention, a slit for sandwiching a part of the ear is formed in a part of the ring body, and the side surface (width) of the ring body is compared with the (thickness) between the inner and outer circumferences of the ring body. It also relates to an ear cuff, which is characterized in that the side surface portion of the annular body is pressurized so as to be wide.

Further, in the present invention, the distance (width) between the left and right side surfaces of the ring is shorter than the distance between the inner peripheral surface and the outer peripheral surface of the ring, so that the ring is formed in a wide plane and is part of the ring ear cuff. A slit for sandwiching a part of the ear is formed, and the gap expanding direction (circumferential direction of the annular body) at both ends of the annular body facing each other by the slit, and the axial direction of the annular body at both ends of the slit. The present invention relates to an ear cuff characterized by having a spring force in an asymmetric direction (twisting direction) toward.

As described above, the present invention is an annular ear cuff for attaching to an ear, and the annular ear cuff is a distance (width) between the left and right side surfaces of the ring as compared with the distance between the inner peripheral surface and the outer peripheral surface of the ring. ) Is short, which makes the plane of the ring (both left and right sides of the ring) flat and wide, and only a slit is formed in a part of the ring ear cuff to hold a part of the ear. Therefore, the structure is simple, and the distance (width) between the left and right sides of the ring is shorter than the distance between the inner and outer surfaces of the ring, which makes it a wide plane. The aesthetics can be maintained regardless of the material.

In addition, since the side surface (width) of the annular ear cuff is flat and wide, the elastic force in the circumferential direction and the axial direction (twisting direction) is higher than that of a simple annular body regardless of the material. In addition, because part of the annular ear cuff is separated, elastic force is used to bend both ends of the ear cuff in a twisting direction and widen the distance between both ends to increase the distance between the ends. By sandwiching it in the position, both ends of the slit can surely grab the ear part by elastic force after releasing it, and the ear cuff can be securely attached to the ear without having so much holding force.

An enlarged perspective view of an ear cuff with a wide plane, which is an embodiment of the present invention. FIG. 3 is an enlarged cross-sectional view of FIG. 1B, which is a cross-sectional view of the portion taken along line AA of FIG. 1 before and after processing the material constituting the ear cuff. An enlarged perspective view showing the elastic (biased) direction of the ear cuff of the present invention.

The configuration of the ear cuff according to the present invention will be described below with reference to the drawings.
The enlarged description in FIG. 1 represents an ear cuff formed in an annular shape based on a metal material 1 made of various metals such as stainless steel, copper, and a fine alloy. In this case, the metal material 1 has a circular cross section as shown in FIG. 2 (a) by pressing the material having a circular cross section from the side surface side of the circular material, and the cross section is as shown in FIG. 2 (b). Can be processed into.

As shown in FIG. 2B, the ear cuff of the present invention is made of the metal material processed in an annular shape with respect to the distance between the inner peripheral surface 1a and the outer peripheral surface 1b of the metal material processed in an annular shape. The distance (width) between the left and right side surfaces 1c and 1d is short, and the surface is formed flat and wide in proportion to the cross-sectional mass of the narrowed width between the left and right side surfaces, and is formed in an annular shape. A slit S for sandwiching a part of the ear is formed in a part of the ear cuff 1.

That is, the present invention is an annular ear cuff that can be attached to various parts of the ear including the earlobe, and the annular ear cuff is compared with the distance between the inner and outer peripheral end faces (thickness) 1a and 1b of the ring. The left and right side surfaces (widths) 1c and 1d of the ear cuff formed in an annular shape are plastically deformed by the amount of flat end surfaces to become wider (see FIG. 2 (b)). Moreover, a slit S is formed in a part of the annular ear cuff, which is cut so as to be sandwiched between the earlobe or both sides of the ear and separated at a certain interval (thinner than the thickness of the earlobe).

If the corners of the separated slit S are sharp, it is easy to damage the ear when it is attached to or removed from the earlobe or the like, so it is desirable that the slit S is as round as possible. Regarding both ends of the slit S separated in this case, for example, the corners are melted so as to be rounded by laser processing, or an adhesive or the like is applied to cover the sharp corners. Eliminating this will improve usability without injuring your ears.

As a preferable processing method for the annular ear cuff, an annular metal material having an endless shape is obtained from a general linear metal material having a cross section as shown in FIG. 2 (a), and the endless metal material is used. For example, even if the width side of the annular metal material is placed on a flat base (lower mold) in a press machine and then the upper mold is lowered from above to be pressed and deformed, or it is crushed by a roller type pressurizing device. good.

Finally, a cut is made in a part of the ear cuff material formed in an annular shape to form a slit S, and the sharp portion of the slit S is laser-processed or an adhesive is applied as necessary. It is completed by finishing it so as not to hurt the ear when it is attached to or removed from the earlobe.

As described above, the metal material of the annular ear cuff is the distance (width) between the left and right side surfaces of the ring (width) 1c and 1d compared to the distance between the inner peripheral surface and the outer peripheral surface of the ring. (Thickness) is short, which makes it a wide plane, and the distance (width) between the left and right sides of the ring is larger than the distance between the outer peripheral surfaces 1a and 1b. By pressing and pressing so as to be shorter, the entire ear cuff is plastically deformed, and the latent spring force of the entire ear cuff is improved in proportion to the amount of pressing and deforming of the metal plastic portion of the flatly deformed side surface (width).

Regarding the latent spring force at the slit S portion, which is the cut of the ear cuff according to the present invention, as shown in FIG. 3, in the slit S portion, the annular direction is expanded in the l1 direction and the l2 direction. The spring force in the direction and the spring force in the twisting directions opposite to those in the m1 and m2 directions are exerted with respect to the axial direction of the annular body.

As a result, both ends of the slit S are attached to any part of the ear while twisting one side to m1 and the other side to m2 in opposite directions to open the space between both ends of the slit S and let go. Both ends of the slit S are restored by the spring force and narrowed, and they are attached in a state of being pinched by the ears as they are. By utilizing the spring force provided in the annular body 1 in this way, the ear cuff of the present invention improves the wearability when it is attached to the ear, and there is almost no deterioration in the spring force of the slit S for attaching to the ear. , You can get a durable ear cuff. Further, it is not necessary to insert an unsightly part such as a spring for maintaining and reinforcing the attachability as in Patent Document 4 described, for example.

With such a configuration, the light reflecting surface of the flat surface wide portion 1c / 1d, which is the side surface (width) of the ear cuff formed in an annular shape when worn on the ear, is increased, so that the ear cuff alone can be worn. Since the exposed area of the side surfaces (width) 1c and 1d with respect to the outer peripheral surfaces (thickness) 1a and 1b is increased, the light brightness of the side surface (width) is remarkably improved, and a considerable decorative effect can be expected. Further, in this case, another decorative material (for example, a chain decoration (not shown)) can be passed through the ear cuff with the increased light reflecting surface of the flat surface wide portion 1c / 1d to further enhance the decorative effect.

Further, the metal used in this case has a circular cross section or a substantially square cross section, or the like, as compared with a linear body having a general circular cross section as shown in the cross section (a) of FIG. The striatum with little difference in cross-sectional plastic amount (mass difference) is made into an annular shape, and the entire annular body is pressed in the plane direction (side surface 1c / 1d direction) to be shown in FIG. 2 (b). An ear cuff having good springiness can be obtained by using an ear cuff having a wide cross-sectional shape on a flat surface having a plastic difference (mass difference) in the vertical and horizontal portions.

The ear cuffs to which springiness is imparted over substantially the entire area of the ear cuffs as described above have side surfaces because the exposed areas of the left and right side surfaces (widths) 1c and 1d with respect to the distance (thickness) between the inner and outer peripheral surfaces 1a and 1b increase. (Width) The light reflection brightness of 1c and 1d is remarkably improved, and a large decorative effect can be expected. In addition, it is not necessary to attach a spring or the like to attach the spring to the earlid or the like for a long time or to complicate the configuration.

As described above, according to the ear cuff according to the present invention, there is no need for a separate component such as a spring to be attached to the ear, and the attachment to the ear is good, simple and durable. You can get rich and good looking ear cuffs.
