Description

TECHNICAL FIELD The present invention relates to a fastener that utilizes the elasticity of a string to form a ring.

Many parts of jewelry, such as collars (chains), are made of metal, and many people avoid wearing them due to metal allergies. With the rise in metal prices, many new materials are being created to replace metals. On the other hand, although many devices have been made that fix the ends of strings together, there are only a few types of devices that can adjust the length at the same time. To name a few, there are many synthetic resin cord stoppers with built-in metal springs. It is a convenient stop that can be easily slid to adjust the length. In addition, you can make a loop by ligating the ends of a string together using the familiar tying motion.

However, cord stoppers that are easily available at stores do not have a very strong grip on the string, and can easily move if you pull only one string, so they are easily seen as temporary stops, and their shape is cylindrical. Many of them are bulky and difficult to use as part of accessories that will be used for a long period of time. On the other hand, when tying a knot using a string, the knot tends to become extremely raised or unbalanced between the left and right sides, and elaborate and beautiful knots like the flower knot are not suitable for accessories that are often worn on a daily basis. .
In addition, the string end stopper in Patent Document 1 has a complicated structure, and there is no need to fix the string so strongly.It is used to fix the string end, and the length of the collar can be adjusted to the desired length. It cannot be adjusted.

In order to solve these problems, the present invention makes the base into a flat plate shape that does not feel uncomfortable, makes gourd-shaped holes in three places, and threads strings through the holes in order to increase the flexibility of the strings. To provide a stopper for making a loop of a string that does not come off by utilizing the tightening of the strings.

The problem we are trying to solve is that it is possible to easily and reliably create a ring from a single string by holding both ends of the string, and the size of the ring can be adjusted freely, and it also makes it look stylish on the back. The task is to provide a useful stop.

The present invention uses elastic strings that, unlike metal, deform slightly when pinched with fingers, by crossing them through the narrow part of the hole, creating a shape that tightens each other, and friction that resists pulling by rubbing against each other. It is characterized by having gourd-shaped holes in three places on the base, paying attention to the fact that the force increases and prevents it from coming off. Increasing the number of holes makes it difficult for the string to come off during use, but on the other hand, it complicates the work of passing the string through the holes and requires more effort to remove the string from the base. The optimum number of holes to be set is three.

The reason for choosing the gourd-shaped hole is to make it easier for the two strings passing back and forth to pass through the hole, and having the strings intersect at the constriction has the advantage of making the tightening more reliable.
Compared to a gourd-shaped circular hole, if you use one large circular hole, there will be more gaps and play will occur more easily when the strings cross and pass through.
Depending on the outer shape of the base of the stopper, the gourd-shaped holes may be arranged at three locations in a straight line, or at three triangular positions.
The shape of the hole is a gourd-shaped hole that has two minimum openings for the string to pass through and has a constriction in the middle. It is important to make the width of the knot smaller than the width of the string opening. To prevent the strings from coming off, it is important to cross the strings in three places so that they tighten together.

Next, I will explain how to remove the looped string. Push back the string end sticking out on one side, pick up the lifted string on the other side with your fingers, and remove it in the reverse order of attachment. Once you have finished removing it from all three holes, grab the other end of the string and pull it a little harder to easily remove the entire string.

In the process of making a ring using the product of this invention, the characteristics of the string are used to tighten each other, making it difficult to come off, while the length of the ring can be easily adjusted by returning part of the string, and the string can be removed. It has the advantage of being able to be replaced with a new string. Furthermore, it will also play a role as a part of the decoration that enhances the back side. Not only is it effective for metal-free, which is one of the objectives of the present invention, but it also makes it possible to reduce the proportion of metal used in decorative items that have conventionally mainly used metal parts. .

By creating a shape in which a single elastic string can be tightened together through multiple gourd-shaped holes provided in the base of the stopper, we were able to create a ring that does not come off.
The base material is selected from light and durable materials such as wood, resin, paper, ceramics, glass ceramics, and glass. Metal plates can also be used.
Various shapes can be selected for the base, including hearts, buttons, animals and plants, Mt. Fuji, dolls, and characters. One option is to use a shape of the holding part of the base that is an arrangement of the marks of playing cards.
Depending on the shape, natural fibers, leather, synthetic fibers, rubber, and metal chains can be used as materials for the string. The thickness is appropriately selected and used depending on the purpose.
For an even more luxurious look, traditional crafts can be applied to the base.
One of the latest inventions in the string material that is currently attracting attention is the dream fiber: spider thread, which we would like to incorporate as long as it is in a form that is compatible with the present invention.

We will explain how to make a pendant by passing the string (4a) through the hole in the holding part of the ceramic pendant head (2) and then stopping both ends of the string with the glass-ceramic fasteners of the present invention to create a collar. .
When making a pendant head, the clay is made 10% to 15% larger in consideration of shrinkage after firing. First, prepare two 4mm thick ceramic plates cut into 4.8 x 3.5cm squares. Next, a wax sheet with a thickness of 1.5 mm is cut into 1.8 cm square pieces, sandwiched between ceramic clay plates, and the surrounding area sealed to serve as a base before firing. Thereafter, the heart-shaped clay that will become the holding part (3) is connected to the upper part of the base. In order to prevent rupture during firing after the clay has properly hardened, a hole with a diameter of approximately 2 mm is drilled in a portion of the lower ceramic plate to a depth where the wax can be seen, and the base is made hollow after firing, thereby reducing the weight of the base. We aim to make this possible. Furthermore, make a hole in the center of the side of the holding part to pass the string that can pass through from side to side. After Raku-yaki, the entire piece is glazed and fired, then decorated with paintings and other decorations, and re-fired to finish.

On the other hand, in the production of the string end stopper, three gourd-shaped holes are made at triangular positions on the base of the stopper, which is made of triangular plate made of glass ceramic and finished with a side of 2.5 cm and a thickness of about 4 mm. . The gourd-shaped holes are oriented vertically so that the criss-crossing creates tightness, and the holes are drilled at right angles to the bottom. In Figure 2, in order to make it easier to understand the flow of string through the six string openings in the gourd-shaped triangular hole, the thickness of the string passing through the left and right holes is changed.
As shown in Figure 2, first pass the tip of the string through the gourd-shaped holes (5) and (10) from the back side of the gourd-shaped holes made in the base, respectively, and pass through the holes (5) → (8). )→(9), (10)→(7)→(6), pass the string through the back → front → back, and the string threading is completed. Pass the strings in this order, and finally tighten the two string ends (4a) and (4b) tightly. This will prevent the strings from twisting in three places. By reducing the diameter of the string at the constricted part, strong resistance is obtained and it becomes difficult to come off. Furthermore, by wrapping the string ends (4b), which are about 6cm long with room left and right, around the strings that pass between (5) and (8) and between (10) and (7), the tightening can be further strengthened and the direction of the string ends can be increased. You can express sexual stability and the fun of entanglements.

Next, to attach it to your neck, use a string with a total length of about 78 cm, leaving about 6 cm at each end of the string (4b) on both sides, and pass it through the hole in the stopper and the hole in the holding part of the pendant. After slipping the collar completely over the head, adjust the size of the collar by moving the strings from both ends.
By using the string end stopper of the present invention, an accessory with a new design that uses no metal at all and takes advantage of the metal-free feature can be created.

If the base serving as the fastener of the present invention has an elongated shape, three vertical gourd-shaped holes are provided in a straight line.
As shown in Figure 3, pass the string ends on both sides through the gourd-shaped holes provided in the base of the stopper from the front side of the openings (11) and (16). Pass the string through the front, back, and front in the order of (13) → (15), (16) → (14) → (12). In Figure 3, in order to make it easier to understand the flow of the string, the flow of the string from entrance (11) → (13) → (15) is shown by a thick line, and the flow of the string from entrance (16) → (14) → (12) is shown by a thick line. The flow is shown as a thin line.
FIG. 4 shows an enlarged cross-sectional view taken along the line AA at the constriction in the center of the gourd-shaped holes drilled at three locations in the base of the rectangular fastener in Example 2. At this constriction position, the collar side string (4a) and the string end side string (4b) intersect and tighten each other, and the thickness of the string is shown reduced in diameter. If this condition also exists at the other two intersecting points, a strong resistance to dislodgement is created, and as a result, the loop made of string is held.
The fastener in Example 2 can also be used for bundling objects, regardless of their size.

Various types of accessories can be made by using a ring-shaped string made from a single string using the stopper of the present invention and using conventional accessory parts such as a round ring. Furthermore, the cord end stopper of the present invention can be used reversibly.
The above description is a specific example of the present invention, and does not limit the scope of the claims.
