DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pierced earring, and more particularly to an earring body composed of a pair of front and back members, which are connected to each other by a shaft so as to be freely opened and closed, and provided at an open end of one of the members. The present invention relates to a pierced earring in which a pin is inserted into a hole in an earlobe, and a retaining portion provided at an open end of the other member is fitted into the pin so that the pin can be easily stopped on the back side of the earlobe. Things.

[0002]

2. Description of the Related Art FIG. 12 shows a conventional example of a typical piercing earring. That is, a decorative body 51 having pins 52 attached to the back surface, a substrate 54 having a pin through hole 55 in the center,
A stopper 53 called a catch is provided with a pair of resilient circular loops 56 extending both ends of the substrate 54 and bent in directions facing each other. However, since the attachment and detachment of the stopper are troublesome and the stopper itself is easily lost, it has been required to integrate the decorative body with the pin attached and the stopper.

[0003] For this reason, FIG. 11 (JP-A-60-2428)
05, one member 41 of a pair of members 41, 42 connected by a hinge 44 having a shaft 43.
A pin 45 is attached to the open end of the
At the open end, a simple projection-shaped locking portion 48 is formed on the inner periphery of the accommodation opening 47, and the pin 45 is also formed with a groove 46 corresponding to the locking portion 48.

[0004]

However, in the pierced earring in which the decorative body to which the pin is attached and the stopper are integrated, the tip of the pin 45 abuts on the projection-shaped engaging portion 48, and the inner circumference of the pierced earring is pressed. There is a serious drawback that the pin 45 is easily bent to the side, and the pin 45 and the locking portion 48 are loosely engaged during use and easily come off.

[0005] Further, in the above-mentioned hinge 44 structure, although the rotary motion is performed, a hand for stopping the horizontal movement is provided by the shaft 43.
However, there was a drawback that it was easy to loosen. For this reason, if the shaft is firmly attached, it becomes difficult to rotate and cannot withstand use, and if the shaft is loosely attached, the shaft attached portion is loosened during use and easily shakes.

When the pair of members 41 and 42 are closed, the pin 45 provided at the open end of one of the members 41 comes off the housing opening 47 provided at the open end of the other member 42. Not only cannot be easily set on the back side of the earlobe, but also the pin 45 is not stopped in the accommodation opening 47. Become. That is, the pin 45 easily falls out of the hole in the earlobe.

Further, since the entrance of the accommodation opening 47 is narrow, the tip of the pin 45 abuts against the end face of the accommodation opening 47, and when pressed further, the pin 45 bends inward, bends left and right, or The groove 46 of the pin 45 is broken or the groove 46 of the pin 45 is
8 cannot be engaged, and there is a disadvantage in that it cannot withstand use.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks. In order to easily stop the pin on the back side of the earlobe, the tip of the pin is guided by the open end of the other member. It is accurately guided to the position, and the pin locking part can be securely inserted into the guide locking part, and the elasticity and biasing force of the pin will decrease for a long time even if it is used repeatedly. It aims to provide pierced earrings without any failure.

[0009]

That is, in the pierced earring according to the present invention, one end of a pair of members constituting the earring main body is formed of a bifurcated bearing portion and a rotating portion fitted into the bearing portion, respectively, and both are shafted. The other end is provided with a pin having a first locking portion on the outer periphery at the open end of one member, and the other member is provided with a pin at the open end of the other member. Has an open end on the inner peripheral side of the first end.
A second engaging portion that engages with the engaging portion, and furthermore, in a shaft attachment portion formed by a bearing portion and a rotating portion, the pair of members has a closing angle determined by the thickness of the earlobe. A rotation restricting piece that prohibits closing is formed by extending the inner peripheral side of the rotating part to the opposite side of the rotating part shaft hole, and this rotation restricting piece is engaged with the bottom surface of the inner peripheral of the member having the bearing part. It is characterized by doing so.

[0010] In the above, it is also characterized in that a stopper is provided at a predetermined position from the second locking portion provided on the guide, for stopping the further entry by abutting the tip of the pin.

[0011]

In the pierced earring according to the present invention, the durability of the pin can be remarkably improved, and the pin can be easily stopped at the back of the earlobe.

That is, in the present invention, the pin is located substantially on the circumference of the earring body composed of a pair of arc-shaped members. And since the bearing part of the shaft attachment part is reinforced so as to have a predetermined thickness and length, the pair of members does not shake laterally, and the tip of the pin is guided by the open end of the other member. Guided precisely to position.

In addition, since the guide which allows the pin to enter in the length direction is narrowed while inclining the entrance wide inward and inward, the guide may be moved in the process of the pin passing through the guide. The pins are bent so that they gradually flex inward while moving along the slope. With such a guide inclined inward without difficulty, it is possible to provide a pierced earring which does not apply excessive force to the pin and which can be used for a long time without failure.

Further, when the pin is disengaged from the guide and the pair of members intersect when the pair of members are closed, the interval between the bearing portions is widened by the lever principle in the related art. As a result, the pin is loosely moved to the left and right due to the backlash of the shaft-attached portion, so that the pin cannot be reliably guided to the guide. Since the pin is not pushed beyond the closing angle when it is at the position of the second locking portion, and the interval between the bearing portions does not increase, the pin can be reliably guided to the guide.

Furthermore, if there is any deviation in the shaft attachment portions of the pair of members, the pin will be displaced. In such a case, the guide has a wide entrance, so that this guide absorbs the lateral movement and the tip of the pin is accurately guided to the position of the inclined surface in the guide of the other member, and the first The locking portion can be securely fitted into the second locking portion. Further, at that time, the first locking portion of the pin is moved by the rotation restricting piece to the second locking portion in the guide.
Of the pin can be prevented from being pushed in more than the locking portion, so that the diameter of the tip of the pin does not become smaller than the position on the circumference of the earring main body. Therefore, the elastic force of the pin is not impaired, and the urging force does not decrease.

The guide that allows the pin to enter in the longitudinal direction is narrowed while widening the entrance inward toward the back and narrowing the guide. Is formed as the second locking portion, so that the pin which has entered while gradually bending the inside of the guide within the range of its own elasticity, finally has the first locking portion inside the guide. , The second engaging portion, that is, the step. At this time, since the step is formed deeper than the height of the portion from the first locking portion of the pin, the force applied to the tip of the pin toward the inner side of the guide is not enough to bend. The pin is released and the pin is released from tension and engaged on a near circumference before entry.

Further, when using the pierced earring of the present invention in which the guide of the pin to the guide and the mounting are performed on the back side of the earlobe, as described above, the tip of the pin does not swing left and right, and the open end of the other member does not move. Since the guide is accurately guided to the guide position, by opening the pair of members and inserting the pins into the earlobe, it can be attached to and removed from the earlobe with one hand and one touch. Still, if the pin slightly oscillates left and right, the guide absorbs this horizontal sway and there is no problem.

As described above, according to the pierced earring of the present invention, it is possible to provide a pierced earring that does not cause any trouble for a long period of time even when used repeatedly.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the drawings.

1 to 10, the earring body 11 is composed of a pair of arc-shaped members 1 and 1 '. One end of the earring body 11 is rotatably mounted on a shaft 8 via a shaft 8, and is rotatable in a direction in which its open ends are abutted. Connected. 9 is the above member 1,
A jewel attached to 1 'as a decoration.

The members 1 and 1 'are not limited to the above-mentioned arc shape.
As long as the earlobe can be inserted between the pair of members 1 and 1 ', various shapes such as an ellipse, a rectangle, a rhombus, and a triangle can be used. The cross section can also be determined as appropriate, but since it is hung from the earlobe, if the pierced earring itself is heavy, the hole in the earlobe becomes large, and it is said that it is desirable to make it as light as possible to avoid standing out when the pierced earring is removed For this reason, it is desirable to form a gutter having a predetermined thickness.

A pin 2 provided with a V-shaped or U-shaped groove-shaped first locking portion 3 on the outer periphery of the open end of the one arc-shaped member 1 is formed by brazing. Have been. The pin 2 is preferably bent at a predetermined curvature along the arc of the arc-shaped member 1, 1 '. If the pin 2 is straight and brazed to the open end of one of the arc members 1, both of the arc members 1, 1 ′ rotate about the shaft 8 and the open ends protrude. Are combined. that time,
When the tip of the pin 2 enters the inclined surface 6, a lever action is exerted on the pin 2, and there are disadvantages such as that the portion where the pin 2 is brazed may be bent inward. Therefore, in order to eliminate this drawback, it is desirable to reinforce both the elasticity and the urging force by, for example, rolling the pin 2 in the width direction so as to have a vertically long section after brazing the pin 2. Even if an elastic material is selected as the pin 2, the pin
Is softened by exposure to high temperatures, becomes soft, and its elasticity and urging force decrease. In addition, when the pins 2 are brazed in a straight line as described above, this must be solved on the premise that the principle of leverage is added. Therefore, a method such as bending the brazed pin 2 is preferable. After bending, it is desirable to reinforce both the elasticity and the urging force by rolling the pin 2 in the width direction so as to have a vertically long section. Considering the above-described method, it is necessary to disperse the force applied to the pin 2. The pin 2 is bent at a predetermined curvature, and the pin 2 is rolled in the width direction so as to have a vertically long section. It is desirable to strengthen both power and bias. In the pair of arc-shaped members 1 and 1 ', a pin 2 is formed at the open end of one of the arc-shaped members 1 by selecting a material and projecting it with an elastic round wire by brazing. The pin 2 is bent at a predetermined curvature along the arcs of the arc-shaped members 1 and 1 '. This bent round wire pin 2 is rolled in the width direction so as to have a vertically long section, and both the elastic force and the urging force are strengthened, and the first locking portion 3 is provided at a predetermined position. The first locking portion is provided as a V-shaped or U-shaped groove on the outer periphery of the pin 2 at a predetermined position near the tip of the pin 2. The first locking portion 3 must be provided in consideration of the balance between the rotation restricting piece 23 and the stopper 7.
That is, when the operation of closing the pair of arc-shaped members 1 and 1 ′ is performed and the first locking portion 3 is engaged with the second locking portion 4, the outer peripheral bottom surface of the rotation restricting piece 23 is a bearing portion. The pin 2 engages with the inner bottom surface 24 of the gutter-shaped member 1 ′ and has a function of protecting the elastic force and the urging force of the pin 2. The first locking portion 3 may be provided on the outer periphery of the pin 2 in consideration of the above-described balance. In addition, the balance with the stopper 7 must be considered. The stopper 7 is provided so as to be equal to the length from the first locking portion 3 of the pin 2 designed from the above-mentioned balance to the tip of the pin 2. When the open ends of the arc-shaped members 1 and 1 'are butted against each other, they are rotated about the shaft 8, so that they are drawn so as to draw a circle having a diameter slightly larger than the arc. Although the depth of the groove of the first locking portion 3 changes according to the thickness of the pin 2, it is approximately half the thickness of the pin due to strength.
Or it needs to be slightly larger. It is desirable to form a tapered inclined surface 6 ′ also at the tip of the pin 2.

At the open end of the other member 1 ', there is formed a guide 5 which allows the pin 2 to enter. The guide 5 has a substantially conical cross section as shown in the enlarged perspective view of FIG. 10, and a part thereof is cut away to form a groove. That is, the guide 5 is formed of an inclined surface 6 having a half-conical cross-section that widens from the open end side and gradually narrows toward the back. Therefore, even if the pin 2 slightly swings right and left by the guide 5, the second locking portion 4
The pin 2 is smoothly fitted into the guide 5 because it is guided to the inside. Further, since the inclined surface 6 is formed so as to extend inward toward the back, the pin 2 is gradually bent inward within the range of its own elasticity while moving along the inclined surface 6, and rebounds. Power has been increased.

At the end of the guide 5, a second locking portion 4 which engages with the first locking portion 3 is formed on the inner peripheral surface of the arc-shaped member 1 '. In the figure, this second locking portion 4
The guide 5 is formed as a step provided at the rear end of the inclined surface 6 and extending outward from the rear end. Thus, when the first locking portion 3 at the tip of the pin 2 passes through the second locking portion 4, the pin 2 moves in the direction of increasing the diameter by the repulsive force, and the first locking portion 3 is moved. The second engaging portion 4 is engaged. At this time, as shown by h in FIG.
Is formed to be deeper than the height of the portion from the locking portion 3 of the pin 2, so that the repulsive force applied to the pin 2 is released, so that no excessive load is applied to the pin 2 and the elasticity of the pin 2 is reduced. It can be maintained for a long time. In addition, since the pin 2 is not bent inward more than its elasticity as described above, the engagement between the first locking portion 3 of the pin 2 and the second locking portion 4 in the guide 5 during use. Is not easily loosened.

It is necessary that the pin 2 has elasticity so that the first locking portion 3 is biased in the direction of the second locking portion 4. When the open ends of the arc-shaped members 1 and 1 ′ are abutted against each other, the pin 2 is abutted so as to draw a circle having a diameter slightly larger than its own arc. The guide 5 strikes the guide 6 at an acute angle, and moves along with the inclined surface 6 of the guide 5 without difficulty due to the elasticity. Then, when the first locking portion 3 of the pin 2 is fitted into the second locking portion 4 in the guide 5, the pin 2 stops.

Further, a stopper 7 is provided at the inner peripheral surface of the arc-shaped member 1 ′ at a position deeper than the second locking portion 4 to abut the tip of the pin 2 to prohibit further entry. , Are formed toward the center of the arc. This stopper 7
Is configured such that the distance from the first locking portion 3 of the pin 2 to the tip of the pin 2 is substantially equal to the distance between the second locking portion 4 in the guide 5 and the pin 2. Has entered and the first locking portion 3 has engaged with the second locking portion 4,
The tip of the pin 2 also strikes the stopper 7, and the pin 2 stops at that position. The stopper 7 is formed such that a projection or an obstacle generated from the pedestal of the jewel 9 or the arc-shaped member 1 ′, or from the design, has a length substantially equal to the length from the first locking portion 3 of the pin 2 to the tip of the pin 2. If they are at the same position, they can function as the stopper 7.

As shown in FIG. 7 to FIG. 9, the shaft-mounted portion of the shaft 8 has a plate-like shape in which one end of the pair of members 1 and 1 'is fitted into a forked bearing portion 21 and a bearing portion 21, respectively. , Which are openably and closably connected via a shaft 8 mounted in a shaft hole 8 ′.

The bearing portion 21 of the bearing portion is formed to be longer than the turning radius of the rotating portion 22 on both sides of the bearing portion shaft hole 8 ', and has a predetermined thickness at each of the two forks. Therefore, when opening and closing the pair of members 1 and 1 ', the tip of the pin 2 provided at the open end of one member is accurately fitted into the position of the guide 5 provided at the open end of the other member. Be guided. Since the bearing portion 21 has a predetermined thickness, the opening and closing operation of the pair of members 1 and 1 ′ does not cause the gap between the two forked bearing portions 21 to be loosened. Therefore, the pin 2 does not swing right and left,
The guide 5 is securely inserted.

When the pair of members 1 and 1 'cross each other, the rotation regulating piece 23 functions effectively, but the bearing 2
By making 1 have a predetermined thickness and length, the disadvantage at the time of intersection can be surely eliminated. As shown in FIGS. 1, 5 and the like, the shaft 8 is inserted into the shaft hole 8 'and the pair of members 1 and 1' are mounted on the bearing portion 21. The shaft 8 is visible in the drawing. As shown. However, after the shaft 8 is inserted into the shaft hole 8 ', the shaft 8 is prevented from coming off from the outside of the bearing portion 21 by brazing or caulking, and is further polished. The predetermined thickness and length of the bearing portion 21 play a necessary and important role also in the steps of brazing, caulking, polishing and the like.

Reference numeral 23 denotes a rotating part 2 provided at the end of one of the members 1 in the shaft attachment portion of the pair of members 1 and 1 '.
2 is a rotation restricting piece formed so as to extend on the arc formed by the member 1 so that the inner diameter side of the member 2 extends toward the opposite side of the rotating shaft hole 8 '.

The pair of members 1, 1 'are closed at their open ends and the pin 2 is inserted into the guide 5, and the first locking portion 3 is
Is fixed when it is connected to the locking portion 4. When the first locking portion 3 is coupled to the second locking portion 4, the rotation restricting piece 23 also engages with the inner bottom surface 24 of the gutter-shaped member 1 ′ having the bearing portion 21. To restrict further rotation. Therefore, the pin 2 does not receive a load greater than the elastic force, and maintains the elastic force for urging the pin 2 in the direction of the second locking portion 4.
Dramatic improvement in durability can be achieved. However, when the pair of members 1 and 1 'are wide or their shaft-attached portions are formed wide, the end surfaces of the shaft-attached portions of the pair of members 1 and 1' are necessarily abutted and rotated. Since it functions as a restriction piece, it can be replaced with the rotation restriction piece 23 having the above structure. When the first locking portion 3 is connected to the second locking portion 4, the pin 2 is exposed between the pair of members 1 and 1 'with a width mainly equal to the thickness of the earlobe.

The joint surface between the rotation restricting piece 23 and the bottom surface 24 on the inner periphery of the gutter-shaped member 1 ′ may be tapered inclined surfaces to improve the strength.

As described above, the rotation restricting piece 23
The first locking portion 3 of the pin 2 is pushed in beyond the position of the second locking portion 4 attached to the guide 5, and the pin 2 is bent inward beyond its elastic force, and the second locking portion 3 is again pressed. The first locking portion 3 is not caught by the second locking portion 4, so that it is possible to prevent the first locking portion 3 from falling off the earlobe and becoming unusable.

When the pin 2 comes out of the guide 5 and the pair of members 1 and 1 'intersects when the pair of members 1 and 1' are closed, a conventional lever is used. According to the principle described above, the interval between the bearing portions 21 is widened, the shaft attachment portion rattles, and the pin swings left and right, so that the pin 2 cannot be reliably guided to the guide 5, whereas in the above embodiment, The first locking portion 3 of the pin 2 is not pushed by the rotation restricting piece 23 beyond the closing angle corresponding to the position of the second locking portion 4 in the guide 5 and the interval between the bearing portions 21 is increased. Therefore, the pin 2 can be guided to the guide 5 without fail. That is, the guide 5 can be easily fitted into the pin 2 behind the earlobe.

A pair of members 1 and 2 are
In order to adjust so that 1 ′ is locked at a predetermined arc position, either the outer peripheral bottom surface of the rotation restricting piece 23 or the inner peripheral bottom surface 24 of the member 1 ′ engaged therewith is ground or ground. Processing such as a prime may be performed.

When using the pierced earring of the above embodiment, as shown in FIG.
As in the case of ordinary earrings, after the pin 2 is passed through the piercing hole of the earlobe, the open end of the other arc-shaped member 1 'may be inserted into the tip of the pin 2 protruding from the earlobe. At this time, the pin 2 slides and enters the inclined surface 6 of the guide 5 formed on the open end of the arc-shaped member 1 ′ with the inclined surface 6 ′, and the tip of the pin 2 gets over the second locking portion 4. First
Is engaged with the second engaging portion 4, and the arc-shaped member 1 is held by the arc-shaped member 1 '. The load applied to the pin 2 at this time is small, and the pin 2 does not bend or fall down from the base to the inner peripheral side. Therefore, the durability of the pin 2 is greatly improved.

The pin 2 is forbidden by the stopper 7 and the rotation restricting piece 23 from pushing the first locking portion 3 farther than the second locking portion 4. 2 does not bend beyond the above elasticity range. Therefore, the arc formed by the pin 2 becomes small, and the first locking portion 3 does not easily come off from the second locking portion 4 and the pin does not easily come off.

When the circle formed by the pair of members 1, 1 'has a small diameter, the rigidity of the members 1, 1' is high.
Since the rotation restricting pieces 23 provided on the shaft attachment portions of the pair of members 1 and 1 'function effectively, the stopper 7 is unnecessary. However, when the diameter of the pair of members 1 and 1 ′ increases, the thickness of the pair of members 1 and 1 ′ having a predetermined thickness, for example, formed in a gutter shape, needs to be reduced. 'It warps itself. Then, the rotation regulating piece 2
3 engages with the bottom surface 24 on the inner periphery of the other member 1 ′, and the pin 2 extends beyond the position where the first locking portion 3 is coupled to the second locking portion 4.
Is pushed in. Therefore, in such a case, it is necessary to provide the stopper 7 at the back of the second locking portion 4 in the guide 5.

According to the present invention, since the tip of the pin is housed in the arc-shaped member, the decorativeness is not impaired, and which of the pair of members 1, 1 'arranged on the front side and the rear side is the earlobe. It may be used on the front side. That is, by changing the jewelry to be attached to each of the pair of members 1, 1 ', or changing the bullion of each of the members 1, 1', or changing the design, one pierced earring can be used in two types. It can be used similarly to pierced earrings.

[0040]

According to the pierced earring of the present invention thus constituted, not only can the pin be easily stopped on the back side of the earlobe, but also the durability of the pin can be greatly improved. it can.

That is, the tip of the pin is accurately guided to the guide position of the open end of the other member, and the first locking portion is moved to the second position.
Can be securely inserted into the locking portion. Further, at that time, the rotation restricting piece can prevent the first locking portion of the pin from being pushed into the second locking portion or more in the guide, so that the diameter of the pin is not reduced. Therefore, the elastic force of the pin is not impaired, and the urging force does not decrease.

When the pin is disengaged from the guide and the pair intersects when the pair of members are closed, the distance between the bearing portions is widened according to the lever principle in the related art. As a result, the pin is rattled to the left and right because the shaft attachment portion rattles, so that the pin cannot be reliably guided to the guide. In contrast, in the present invention, the first locking portion of the pin is located inside the guide. In this case, the pin is not pushed beyond the closing angle in the position of the second locking portion, and the interval between the bearing portions is not widened, so that the pin can be surely guided to the guide.

Further, when the pierce earring of the present invention is used in which the pin is attached to the guide on the back side of the earlobe, as described above, the tip of the pin does not swing left and right, and the guide position of the open end of the other member is used. Will be guided to
By opening the pair of members, it is possible to attach and remove the earlobe with one hand and one touch.
Still, if the pin slightly oscillates left and right, the guide absorbs this horizontal sway and there is no problem.

As described above, according to the pierced earring of the present invention, it is possible to provide a pierced earring that does not cause any failure for a long period of time even when used repeatedly.
