[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a piercing type earring, and in particular, each member of an earring body composed of a pair of front and back members is connected by a shaft so as to be openable and closable, and a pin provided at an open end of one member is provided in an earlobe hole. The present invention relates to a piercing earring in which a pin can be easily stopped on the back side of an earlobe by inserting a retaining portion provided at the open end of the other member into the pin after inserting the pin.

[0002]

[Prior art]

 FIG. 12 shows a conventional example of a typical piercing earring. That is, a decorative body 51 having a pin 52 attached to the back surface, a substrate 54 having a pin through hole 55 in the center, and a pair of elastic circles formed by extending both ends of the substrate 54 and bending them in opposite directions. With a loop 56 and a stopper 53 called a catch. However, since the attachment and detachment of the fastener is troublesome and the fastener itself is easy to lose, it was required to integrate the decorative body with the pin and the fastener.

Therefore, as shown in Japanese Patent Laid-Open No. 60-242805, a simple projection-like locking portion 42 is formed on the inner periphery of the accommodation opening 41, and the pin also has a protrusion corresponding to this locking portion 42. What has been formed (not shown) has been developed [see FIG. 10 (a)].

In addition, one end of the pair of members 31, 31 ′ constituting the earring body, which was previously proposed by the present inventor, is automatically opened and closed in the direction in which the open ends of the other ends are abutted via the shaft 37. A pin 32 provided with a first locking portion 33 on the outer circumference on the open end of one member 31 and the pin 32 on the inner circumference side on the open end of the other member 31 '. A guide 35 having a second engaging portion 34 that engages with the first engaging portion 33 and that allows the tip of the pin 32 to abut. It is also known that a stopper 36 is formed to prevent further intrusion, and the pin 32 has elasticity so that the first locking portion 33 is biased toward the second locking portion 34 (Fig. 11).

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned two types of piercing earrings in which the decorative body to which the pin is attached and the fastener are integrated, in the former piercing earring, the tip of the pin abuts on the projecting locking portion 42 and is directed toward the inner peripheral side. It has a serious drawback in that it is easily bent, and the engagement between the pin and the locking portion is loosened during use and is easily pulled out. It also has the same drawbacks as the latter piercing earrings.

Further, in the latter pierce earring, the shaft attachment portion becomes loose during use, and when the pair of members 31, 31 ′ is closed, the pin 32 provided at the open end of one member 31 Member 31 'does not stop because the pin 32 does not stop after passing through the position (side surface of the open end of the other member 31') that is out of the guide 35 provided on the open end of the member 31 '. If the tip of the pin 32 abuts against the end face of the guide 35 due to slipping out or the inlet of the guide 35 is narrow, and if it is pressed further, the pin 32 bends inward, left or right, or the groove of the locking part There is a drawback that the first locking portion 33 of the pin 32 cannot be engaged with the second locking portion 34 in the guide due to a broken portion, and it becomes unusable.

The present invention is intended to eliminate the above-mentioned drawbacks, and in order that the pin can be easily stopped on the back side of the earlobe, the tip of the pin is located at the open end of the other member. The pin is accurately guided to the guide position so that the first locking part can be securely fitted into the second locking part, and the elastic force of the pin can be maintained for a long time even if it is repeatedly used. The aim is to provide pierced earrings that do not have any trouble and do not lose power.

[0008]

[Means for solving problems]

 That is, in the piercing earring of the present invention, one end of each of a pair of members constituting the earring body is a bifurcated bearing portion and a rotating portion fitted in the bearing portion, and both of them are open ends of the other end through the shaft. The members are pivotally mounted so as to be openable and closable in the direction in which the parts are abutted, a pin having a first engaging part is provided on the outer periphery of the open end of one member, and the open end of the other member is provided with the pin. A second locking portion that engages with the first locking portion is provided on the inner peripheral side, and the inlet is widened and narrowed by inwardly inclining toward the depth of the pin. Is provided with a guide for allowing the first locking portion to enter, and the pin has elasticity for urging the first locking portion toward the second locking portion, and further, the shaft mounting portion including the bearing portion and the rotating portion. In the above, the above bearing part is formed to have a specified thickness and length on both sides of the bearing hole. It is an feature.

It is also characterized in that the second locking portion in the guide is formed by a step extending outward from the rear end provided at the rear end of the inclined surface of the guide.

Further, it is also characterized in that a stopper for abutting the tip of the pin to prevent further entry is provided at a predetermined position from the second engaging portion provided on the guide.

[0011]

[Action]

 With the pierced earrings of the present invention configured as described above, the durability of the pin can be dramatically improved, and the pin can be easily stopped on the back side of the earlobe.

That is, in this invention, the pin is positioned substantially on the circumference of the earring main body composed of the pair of arc-shaped members. Then, 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 can be securely fitted into the second locking portion. Further, at this time, the stopper can prevent the first locking part of the pin from being pushed into the guide more than the second locking part, so that the diameter of the tip of the pin is smaller than the position on the circumference of the earring body. Does not become smaller. Therefore, the elasticity of the pin is not impaired, and the urging force does not deteriorate.

In addition, when the pair of members is disengaged from the outside of the guide and the pair of members intersects when the pair of members is closed, in the conventional one, the interval between the bearing portions is widened by the principle of leverage. Since the shaft mounting part rattles and the pin laterally swings, it becomes impossible to reliably guide the pin to the guide. Since the strength of the bearing portion is increased by forming a predetermined thickness and length on the bearing, the gap between the bearing portions does not increase, so that the pin can be reliably guided to the guide.

Further, when the pin is attached to the guide on the back side of the earlobe, the tip of the pin does not swing to the left or right and the guide position of the open end of the other member is used as described above. It can be attached to the earlobe with one hand and with one touch by opening the pair of members and inserting the pin into the earlobe. If the pins still laterally shake to the left or right, the guide absorbs the lateral shake and there is no problem.

As described above, according to the piercing earrings of the present invention, it is possible to provide the piercing earrings which are free from any trouble even if they are repeatedly used.

【Example】

 Embodiments will be described below with reference to the drawings.

1 to 9, the earring body 11 is composed of a pair of arc-shaped members 1 and 1 ', one end of which is attached via a shaft 8 and which is rotatable in the direction in which the open ends are butted. It is connected. Reference numeral 9 is a jewel attached as a decoration to the members 1, 1 '.

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

A pin 2 having a V-shaped or U-shaped groove-shaped first engaging portion 3 provided on the outer periphery of the open end portion of the one arc-shaped member 1 is projected by brazing. Has been done. The pin 2 is preferably bent with a predetermined curvature along the arc of the arcuate member 1, 1 ′ so that when the open ends of the arcuate members 1, 1 ′ are abutted, they both engage the shaft 8. Since it rotates as a center, it is abutted in a circle with a diameter slightly larger than the above arc. The depth of the groove of the first locking portion 3 varies depending on the thickness of the pin 2, but it is necessary to make the depth approximately half of the thickness of the pin or slightly larger than that in view of strength.

A guide 5 is formed at the open end of the other member 1'to allow the pin 2 to enter. As shown in the enlarged perspective view of FIG. 9, this guide 5 has a substantially conical cross section, and a part thereof is cut out to form a groove. That is, the guide 5 is composed of an inclined surface 6 having a half-divided conical end surface that widens the inlet from the open end side and gradually narrows toward the back. Therefore, the guide 5 reliably guides the pin 2 into the second locking portion 4 even if the pin 2 swings to the left or right, so that the pin 2 is smoothly fitted into the guide 5. Further, since the inclined surface 6 is formed so as to extend inward toward the back, the pin 2 is gradually bent inward within its own elastic range while moving along the inclined surface 6 and repelled. Power is increased.

At the end of the guide 5, a second engaging portion 4 that engages with the first engaging portion 3 is formed on the inner peripheral surface of the arc-shaped member 1 ′. In the figure, the second locking portion 4 is formed as a step provided at the rear end of the inclined surface 6 of the guide 5 and extending outward from the rear end. By doing so, 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 expanding the diameter by the repulsive force, and the first locking portion 3 moves. Engages with the second locking portion 4. At that time, since the repulsive force applied to the pin 2 is released, an unreasonable load is not applied to the pin 2 and the elasticity of the pin 2 can be maintained for a long period of time. Moreover, as described above, since the pin 2 cannot be bent inward more than its elasticity, the first locking portion 3 of the pin 2 and the second locking portion 4 of the guide 5 are engaged during use. Does not become loose and come off easily. It is desirable that the tip of the pin 2 also has a tapered inclined surface 6 '.

It is necessary for the pin 2 to have elasticity so that the first locking portion 3 is biased toward the second locking portion 4. For this elasticity, it is desirable to select the material of the pin 2 to make it elastic and to strengthen the elastic force by rolling the pin 2 in the width direction so as to have a vertically long cross section. When the open ends of the arc-shaped members 1 and 1'abut against each other, the pin 2 is abutted so as to draw a circle having a diameter slightly larger than its own arc, so that the inclined surface of the guide 5 It strikes 6 at an acute angle and, along with the elasticity described above, moves smoothly while sliding along the inclined surface 6 of the guide 5. Then, when the first locking part 3 of the pin 2 is fitted into the second locking part 4 in the guide 5, it stops.

Further, a stopper 7 for abutting the tip of the above-mentioned pin 2 at a position deeper than the second locking portion 4 on the inner peripheral surface of the arcuate member 1 ′ to prevent further entry thereof. Are formed toward the center of the arc. The stopper 7 is configured so that the distance from the first locking portion 3 of the pin 2 to the tip of the pin 2 is approximately equal to the distance to the second locking portion 4 in the guide 5. When the pin 2 enters and the first locking portion 3 engages with the second locking portion 4, the tip of the pin 2 also hits the stopper 7 and the pin 2 stops at that position.

As shown in FIGS. 7 and 8, the shaft-attached portion of the shaft 8 is a plate-like member in which one ends of the pair of members 1 and 1 ′ are fitted into the bifurcated bearing portion 21 and the bearing portion 21, respectively. The rotating part 22 is connected to each other via a shaft 8 mounted in a shaft hole 8 ′ so as to be openable and closable.

Since the bearing portion 21 of the shaft-attached portion has a predetermined thickness on each of the two portions on one side of the bearing portion shaft hole 8 ', the pair of members 1, 1'can be opened and closed. During operation, the tip of the pin 2 provided at the open end of one member is guided so as to be accurately fitted into the position of the guide 5 provided at the open end of the other member. Since the bearing portion 21 has a predetermined thickness, the two-forked bearing portions 21 do not spread and loosen when the pair of members 1, 1'is opened and closed. Therefore, the pin 2 is securely inserted into the guide 5 without swinging to the left or right.

The pair of members 1, 1 ′ are fixed when the open end is closed and the pin 2 is inserted into the guide 5 and the first locking part 3 is coupled to the second locking part 4. It Therefore, the pin 2 is not subjected to a load larger than its elastic force, and the elastic force for urging the pin 2 in the direction of the second locking portion 4 is maintained, so that the durability can be greatly improved. 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.

When using the piercing earrings of the above-mentioned embodiment, as shown in FIG. 5, open a pair of members 1, 1 ′ and, like a normal earring, use the pin 2 as a hole for inserting an earlobe piercing. After passing it through, the open end of the other arcuate member 1 ′ may be fitted into the tip of the pin 2 protruding from the earlobe. At this time, the pin 2 slides into the inclined surface 6'of the guide 5 formed at the open end of the arcuate member 1 ', and the tip of the pin 2 gets over the second locking portion 4. The first locking portion 3 engages with the second locking portion 4 [Fig. 10 (b)], and the arcuate member 1 is held by the arcuate member 1 '. At this time, the load on the pin 2 is small, and the pin 2 does not bend or fall from the root toward the inner peripheral side. Therefore, the durability of the pin 2 is significantly improved.

It should be noted that the pin 2 is prohibited from being pushed further inward than the position of the second locking portion 4 by the stopper 7 so that the pin 2 has the above-mentioned elasticity. Does not bend beyond the range. Therefore, the arc formed by the pin 2 does not become small, and the first locking portion 3 does not easily disengage from the second locking portion 4 and the pin does not easily come off.

In 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 surface side and the rear surface side is used. It may be used on the front side of the earlobe. That is, by changing the jewelry attached to each of the pair of members 1 and 1 ', or changing the metal of each member 1 and 1', and changing the design, one pierced earring can be attached. It can be used as well as other types of earrings.

[Effect of device]

 With the pierced earrings of the present invention configured as described above, the durability of the pin can be dramatically improved, and the pin can be easily stopped on the back side of the earlobe.

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 can be securely fitted into the second locking portion. Furthermore, at this time, the stopper can prevent the first locking part of the pin from being pushed into the guide more than the second locking part, so that the diameter of the tip of the pin is the position on the circumference of the earring body. Will never be smaller than Therefore, the elastic force of the pin is not impaired, and the urging force does not decrease.

In addition, when the pair of members are disengaged from the outside of the guide and the pair of members intersect when the operation of closing the pair of members is performed, in the conventional one, the distance between the bearing portions is widened by the lever principle. Since the shaft mounting part rattles and the pin laterally swings, it becomes impossible to reliably guide the pin to the guide. Since the strength of the bearing portion is increased by forming a predetermined thickness and length on the bearing, the gap between the bearing portions does not increase, so that the pin can be reliably guided to the guide.

When the pin is attached to the guide on the back side of the earlobe, the tip of the pin does not swing to the left or right when using the pier earing ring of the present invention, and the guide position of the open end of the other member as described above. It can be attached to the earlobe with one hand and with one touch by opening the pair of members and inserting the pin into the earlobe. If the pins still laterally shake to the left or right, the guide absorbs the lateral shake and there is no problem.

As described above, according to the piercing earrings of the present invention, it is possible to provide piercing earrings that do not have any trouble for a long time even if they are repeatedly used.
