Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fastener for an earring, particularly a pierce type earring, and an object thereof is to provide a fastener for an earring which is tubular and easy to be gripped by a finger, easy to handle, and easy to manufacture.

[0002]

[Prior art]

 As shown in FIG. 7, a conventional earring fastener, particularly a precious metal fastener, includes a decorative body 21 having a pin 22 attached to a rear surface thereof, a substrate 24 having a pin through hole 25 in a central portion thereof, and a substrate 24 of the substrate 24. And a pair of elastic circular loops 26 having both ends extended and bent in opposite directions, and a stopper 23 called a catch.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional earring stopper, the mechanism portion such as the circular loop 26 for preventing the pin 22 from coming off is exposed, and it is difficult to handle because it is very small. There was a defect that the finger slipped and fell or the finger was injured during the operation of attaching the 22.

Of course, since it has the above-mentioned structure, it has a strong image as a component, and no consideration is given to the design.

In recent years, in place of the above-mentioned conventional earring fasteners, silicon rubber fasteners of various shapes have been proposed in consideration of their design, but they are certain to be worn because there is no “click” feeling. It is uncertain whether or not it has stopped, and there is a drawback that it is difficult to use the decorative body made of an expensive material made of precious metal such as gold or platinum due to its balance.

This invention is intended to solve the above-mentioned drawbacks of the conventional example, and since it has a cylindrical outer shape, its outer surface can be pressed with the pad of the finger, and therefore it is easy to hold with the finger and easy to operate. At the same time, we are trying to provide a fastener for earrings that is also excellent in aesthetics.

[0007]

[Means for Solving the Problems]

 That is, the earring stopper of the present invention has a cylindrical main body having a wide mouth opening at one end and having a tapered tapered end, and a pin body inserted in the center from the wide mouth opening. And a locking plate having a plurality of locking pieces that project toward the inside of the pin insertion hole, and fold the wide-mouth opening of the cylindrical body inward so that the locking plate is inside the cylindrical body. It is characterized in that it is engaged with and the folding surface is used as a pin guide.

The earring stopper of the present invention also has a tapered main body having a wide mouth opening at one end and a guide hole for passing a pin at the other end, and a wide mouth opening. A locking plate that has a pin insertion hole in the center and a plurality of locking pieces that protrude toward the inside of the pin insertion hole. It is also characterized in that the opening portion is folded inward, the locking plate is engaged in the cylindrical main body, and the folding surface serves as a pin guide.

[0009]

[Action]

 Since the fastener for the earring of the present invention is constructed as described above, it has a cylindrical outer shape and its outer surface can be pressed by the pad of the finger, and therefore it is easy to hold with the finger and is very easy to operate.

Moreover, by using the folding surface of the wide opening as a guide, the pin can be smoothly and linearly fitted into the stopper.

[0011]

[Embodiment] Next, an embodiment of a fastener for an earring according to the present invention will be described with reference to the drawings.

In FIG. 1 showing a side view of a fastener of an earring and FIG. 2 showing a sectional view of the fastener, reference numeral 1 denotes a fastener of the earring of the present invention, which is a tubular body 2 and an inside of the tubular body 2. And a locking plate 3 attached to.

That is, the cylindrical main body 2 is formed in a tapered tapered shape, and has a wide-mouth opening 11 at one end and a guide hole 12 through which the pin 4 is inserted at the other end. The taper angle of the tapered end of the cylindrical body 2 may be determined in consideration of ease of molding by pressing or whether the pin 4 is reliably guided in the guide hole 12 direction.

The locking plate 3 is fitted into the tubular body 2 through the wide-mouth opening 11 of the tubular body 2, and engages at a position where its outer peripheral dimension matches the inner circumferential dimension of the tubular main body 2. , Is supposed to be retained.

The locking plate 3 has a pin insertion hole 13 at the center, and a plurality of locking pieces 14 protruding toward the inside of the pin insertion hole 13 are provided. The length of the locking piece 14 is formed to be inside the outer diameter of the pin 4 and outside the depth of the peripheral groove 5. Although the four locking pieces 14 are provided at equal intervals in the drawing, if the number is two or more, they can be appropriately determined in consideration of the ease of attaching and detaching the pin 4.

FIGS. 3 and 4 are a perspective view and a front view showing the assembled state of the locking plate 3, and the locking plate 3 is fitted into the tubular body 2 through the wide opening 11 of the tubular body 2. At this time, it is desirable to form a plurality of inward projections 15 at predetermined intervals around the wall surface of the cylindrical main body 2 so that the locking plate 3 is held at a predetermined position in the cylindrical main body 2.

FIG. 5 shows a sectional view after assembly, and FIGS. 6A and 6B show a front view and a rear view thereof, respectively. As described above, the wide-mouth opening 11 of the tubular body 2 is folded inward, and the locking plate 3 is sandwiched between the inner periphery of the tubular body 2 and the retaining opening 3 so as to prevent the locking plate 3 from coming off.

The folding surface 16 is also formed in a tapered shape that is tapered toward the back and functions as a guide for the pin 4. That is, when the pin 4 is inserted toward the pin insertion hole 13 of the locking plate 3, even if the pin 4 is obliquely inserted, the pin 4 is surely fitted into the pin insertion hole 13. Then, the pin 4 is guided to the guide hole 12 along the taper of the tip of the tubular body 2 and is held in the tubular body 2 smoothly and in a straight line.

When using the stopper of the earring of the present invention, it is sufficient to pinch the stopper 1 with a finger and insert the pin 4 toward the pin insertion hole 13 of the locking plate 3. At that time, even if the pin 4 is obliquely inserted, the folding surface 16 functions as a guide for the pin 4, so that the pin 4 can be securely fitted into the pin insertion hole 13.

After that, the pin 4 is guided to the guide hole 12 along the taper of the tip of the tubular body 2 and held in the tubular body 2 smoothly and in a straight line. At that time, a feeling of "clicking" is obtained at a position where a plurality of locking pieces 14 provided in the pin insertion hole 13 of the locking plate 3 are engaged with the circumferential groove 5 provided in the pin 4, so that it stops there. It has become.

When removing the pin 4 from the stopper 1, the stopper 1 may be pinched with a finger and the pin 4 may be pulled out from the pin insertion hole 13 of the locking plate 3.

[0022]

[Effect of device]

 Since the fastener for the earring of the present invention is configured as described above, it has a cylindrical outer shape and its outer surface can be pressed by the pad of the finger, and therefore it is easy to hold with the finger and is very easy to operate.

Moreover, by using the folding surface of the wide opening as a guide, the pin can be fitted in the stopper in a straight line because the tubular body is used.

Also, unlike conventional fasteners made of precious metal, hair does not become tangled during use and no pain is felt.

Further, since the pin is fixed by the spring built in the locking plate, a feeling of "click" can be obtained, and the stopper is hardly lost even during intense exercise.
