[0002]

2. Description of the Related Art Necklaces, pendants, and other ornamental items to be worn around the neck have a metal fitting attached to the end of a decorative member such as a chain. As one example of this stopper, there is one that is composed of a plate and a pulling ring. This is a hole for locking the pulling ring 12 to the plate 11 attached to one end of the decorative member 1 as shown in FIGS. 4 and 5, for example. On the other hand, the pulling ring 12 which forms 13 and is attached to the other end of the decorative member 1 is located near the fixing portion of the decorative member 1
A narrow opening 12a for inserting 11 is formed, and the opening 12a is closed by a stopper 14 so as to be openable and closable.

The stopper 14 is biased in the direction of closing the opening 12a by a spring built in the main body of the pulling wheel 12 and is slidably mounted on the main body of the pulling wheel 12. Reference numeral 14a in the drawing denotes a protrusion that is formed outside the main body of the pulling ring 12 and is integrally formed with the stopper 14.

In this way, to attach a necklace or other accessory to the neck, the protrusion of the stopper 14 is resisted against the elasticity of the spring.
14a is pressed in the circumferential direction of the pulling ring 12 with a nail or a fingertip to open the opening 12
a is opened, the decoration member 1 is applied to the front of the neck or chest in this state, the plate 11 is inserted into the pulling ring 12 through the opening 12a, and the pulling ring 12 is further inserted into the hole 13 to open the opening 12a. Close with stopper 14. As a result, the plate 11 and the pulling wheel 12 are joined together.

When removing the ornament from the body, the stopper 14 is removed from the opening 12a by the operation reverse to the above, the plate 11 is moved to the opening 12a, the pulling ring 12 is removed from the hole 13 and the plate 11 is pulled. Separate from twelve.

[0006]

[Problems to be Solved by the Invention] In the case of a stopper made up of a plate and a pulling ring, the pulling ring 12 is first
It is necessary to search for the position of the opening 12a formed in the plate 11 and insert the end of the plate 11 therein, and then search for the position of the hole 13 formed in the plate 11 and insert the end of the pulling ring 12 therein. Also,
It is necessary to search the positions of the opening 12a and the hole 13 by the reverse operation also when separating them. Since the opening 12a and the hole 13 are small, the opening 12a is further formed near the fixing portion of the decorative member 1. Therefore, it takes time to find the position. Moreover, since this operation is performed by turning the hand to the back of the neck and cannot be directly seen with the eyes, it is very difficult to perform. Also,
The joint between the plate 11 and the pulling ring 12 is exposed to the outside,
It reduced the value of ornaments that emphasized good appearance.

Therefore, as shown in FIGS. 6 to 8, a plate 2 fixed to one end of a decorative member 1 such as a chain,
When configured with the pulling ring 3 that is fixed to the other end, the plate 2 is, for example, a columnar shape that is displaced near the coupling portion between the upper plate 2a and the lower plate 2b that are coupled at one end. The upper and lower plates 2a and 2b are formed in a circular shape in a plane, the opening 5 is formed except the coupling portion, and the retaining ring 6 is formed on the outer surface of the coupling portion. Set up in.

The pulling ring 3 is formed by cutting out a part of a ring-shaped main body 3a having substantially the same diameter as the plate 2 to form a narrow opening 3b, and the opening 3b is closed by a stopper 7 so as to be openable and closable. This stopper 7 is urged in a direction to close the opening 3b by a spring built in the main body 3a of the pulling wheel 3,
It is slidably mounted on. Reference numeral 7a in the drawing denotes a protrusion that is formed outside the main body of the pulling ring 3 and is integrally formed with the stopper 7. Further, the retaining ring 8 of the decorative member 1 is also provided on the outer surface of the pulling ring 3.

The stopper 7 is pushed in the circumferential direction of the pulling wheel 3 to open the opening 3b, and in this state, the decorative member 1 is applied to the front of the neck or chest, and the pulling wheel 3 is moved up and down through the opening 5 on the plate 2 side. It is inserted between the plates 2a and 2b. And pull ring 3
After inserting the locking pin 4 into the pulling wheel 3 through the side opening 3b, the projection 7a is separated and the opening 3b is closed by the stopper 7. In this way, the pulling ring 3 and the plate 2 are connected, and the pulling ring 3
Fits in plate 2.

With this structure, the joint between the plate and the pulling ring is not directly exposed to the outside, and the appearance is good.

[0011]

However, the devices shown in FIGS. 6 to 8 cannot insert the locking pin 4 into the pulling ring 3 smoothly and reliably. Further, since the retaining ring 6 is provided as a separate body on the outer side surface of the coupling portion of the upper plate 2a and the lower plate 2b, the number of parts is increased and the number of places easily damaged is increased accordingly.

The object of the present invention is to eliminate the disadvantages of the prior art, to improve the appearance of the joint between the plate and the pulling ring without being directly exposed to the outside, and to easily connect and separate the pulling ring and the plate. Moreover, since it is easy to find the position of the locking pin, it is an object of the present invention to provide a fastener such as a necklace that is easy to perform even when working behind the neck and out of sight.

[0013]

In order to achieve the above-mentioned object, the present invention is a stopper such as a necklace composed of a plate and a pulling ring, wherein the plate has locking pins protruding between upper and lower plates, Is a stopper having a partly formed opening for inserting the locking pin, and a stopper for opening and closing the opening is provided in the opening, the upper and lower plates have a large portion facing the mounting portion of the decorative member, The opposite side is a flat, generally keyhole-shaped, and the ends that are narrow are connected to form a retaining ring, and the opening is formed between the upper and lower plates at the other portions, and is also locked. The gist of the pin is a plate shape extending in the longitudinal direction of the plate.

[0014]

According to the present invention, when the pulling wheel is inserted between the upper and lower plates with the opening of the pulling wheel opened, the locking pin is inserted into the pulling wheel through the opening. Therefore, if the opening is closed by the stopper in this state, the plate and the pulling ring are coupled to each other via the locking pin. To separate the plate and the pulling ring, the stopper is pushed to open the opening, and the pulling ring is pulled to remove the pulling ring from the plate.

Further, since the shape of the locking pin is plate-shaped,
Since the surface area of the locking pin is large, it becomes easier to find the locking pin when inserting the pulling ring between the upper and lower plates, and if the opening hits part of the locking pin, slide the pulling ring along this The locking pin can be easily inserted into.

Furthermore, since the retaining rings are formed by connecting the narrowed ends of the upper and lower plates, it is not necessary to separately secure the retaining rings by brazing or the like.

[0017]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a plan view showing an embodiment of a fastener such as a necklace of the present invention, and FIG. 2 is a plan view showing the same in a separated state. The same components as those in FIGS. Is attached.

The stopper of the present invention is also the same as the conventional example in that it is composed of a plate 2 fixed to one end of a decorative member 1 such as a chain and a pulling ring 3 fixed to the other end.

The plate 2 is, for example, one in which a plate-like locking pin 4 is erected vertically by displacing it between the upper plate 2a and the lower plate 2b, one end of which is connected, near the connecting portion. The upper plate 2a and the lower plate 2b are formed in a substantially flat keyhole shape in which a large portion of the upper plate 2a and the lower plate 2b are opposed to the mounting portion of the decorative member and the opposite sides are narrow. This allows the upper plate 2a
Around the space between the lower plate 2b and the lower plate 2b, an opening 5 is formed large except for the coupling portion.

The shape of the locking pin 4 is the upper plate 2a.
And a plate shape extending in the longitudinal direction of the lower plate 2b. Further, the narrowed end portions of the upper plate 2a and the lower plate 2b are coupled with each other as described above, and this shall form a retaining ring.

Next, the usage will be described. To attach a necklace or other accessory to the neck, hook the projection 7a on the nail or fingertip and push the stopper 7 in the circumferential direction of the pulling ring 3 against the elastic force of the spring to open the opening 3b. The member 1 is applied to the front of the neck or chest, and the pulling wheel 3 is inserted between the upper and lower plates 2a and 2b through the opening 5 on the plate 2 side. Then, after the locking pin 4 is inserted into the pulling wheel 3 through the opening 3b on the pulling wheel 3 side, the projection 7a is released and the stopper 7 closes the opening 3b. In this way, the pulling ring 3 and the plate 2 are coupled, and the pulling ring 3 is housed in the plate 2.

When inserting the pulling ring 3 into the plate 2,
Since the opening 3b of the pulling ring 3 is located near the locking pin 4,
It is easy to match the opening 3a with the locking pin 4.

Since the locking pin 4 has a plate-like shape, it has a large surface area, so that when the pulling ring 3 is inserted between the upper and lower plates 2a and 2b, the locking pin 4 can be easily searched for, and the opening 3b is one of the locking pins 4. If it hooks on the part, the pulling ring 3 can be slid along this and the locking pin 4 can be easily inserted in the pulling ring 3.

When removing the ornament from the body, the stopper 7 is removed from the opening 3b by the operation reverse to the above, and then the opening 3
If the locking pin 4 is pulled out from the main body 3a of the pulling wheel 3 via b,
The plate 2 comes off the pulling wheel 3.

[0025]

[Effects of the Invention] As described above, the fastener of the present invention such as a necklace has a locking pin inserted through an opening in a pulling ring,
Or you can easily connect the pulling ring and the plate just by pulling out,
Since it is separable and the position of the locking pin is easy to find, it is easy to do the work behind the neck, where it is not directly visible.

Further, in the coupled state, the pulling ring is completely contained in the plate and cannot be seen from the outside, so that the appearance is good.

Further, since the locking pin has a large surface area, it becomes easy to search for the locking pin when the pulling ring is inserted between the upper and lower plates, and if the opening engages with a part of the locking pin, the pulling ring slides along this. The locking pin can be easily inserted into the pulling ring, and since the retaining rings are formed by connecting the narrowed ends of the upper and lower plates, the retaining ring is fixed separately by brazing, etc. You don't have to.
