Description

Wire rods and processed products made from them

[0001] The present invention relates to a wire rod and a processed product using the same.

[0002] There are many different types of wire rods and they are used in a variety of processed products. Wire rods can be made of paper or metal, such as wire or cord. Mizuhiki, a type of paper wire rod, is used, for example, in mizuhiki crafts. Mizuhiki crafts are a traditional Japanese craft created by bending, tying (braiding), tying, or binding wire rods (see Patent Document 1). Note that "tying wire rods" refers to making one or more knots with one or more wire rods or tying two wire rods together. Furthermore, "tying" refers to tying wire rods to other wire rods or other components. In the following description, bending, tying (braiding), and tying wire rods may be simply referred to as "deforming or processing wire rods."

[0003] Registered Utility Model No. 3193453

[0004] Paper wire is flexible and can be easily bent, knotted (braided), and tied. However, paper wire is more brittle than metal wire, and can bend or break when deformed. Therefore, when crafters deform paper wire to create a workpiece, they must use delicate force.

[0005] On the other hand, metal wires are strong. However, wires are prone to plastic deformation and cannot be bent, knotted, or tied neatly. Although wires are less prone to plastic deformation than wires, they are more difficult to bend, knot, or tie than paper wires, and may even undergo plastic deformation such as bending. Furthermore, the smaller the bending radius of these metal wires, the more difficult it is to bend, knot, or tie them. Furthermore, the more complex the knotting method, the more difficult it is to tie these metal wires.

[0006] For the reasons mentioned above, the paper and metal wires have the problem that they are difficult to deform into the shape intended by the manufacturer, such as bending at the intended bending radius. Furthermore, when the paper and metal wires undergo plastic deformation such as bending, they lose their original properties, and the bend remains even when both sides of the bent part are pulled.

[0007] To provide a wire rod which is strong, resistant to plastic deformation, capable of undergoing fine and complex deformation, can be easily deformed into a shape intended by a manufacturer, and is resistant to fraying even when deformed, and a processed product using the same.

[0008] The wire comprises an intermediate wire in which one or more second wires made of a soft metal are twisted around the outer periphery of a first wire made of a soft metal, and one or more third wires made of a soft metal, and the one or more third wires are twisted around the outer periphery of the intermediate wire, with the twist pitch of the second wires being longer than the twist pitch of the third wires.

[0009] The first wire, the second wire, and the third wire are preferably made of a noble metal or an alloy containing a noble metal.

[0010] The first wire rod, the second wire rod and the third wire rod each preferably have a diameter of 0.05 mm to 0.50 mm.

[0011] The twist pitch of the second wire is preferably 1.0 to 5.0 times the twist pitch of the third wire.

[0012] The twist pitch of the third wire is preferably 0.5 to 1.5 times the product of the diameter of the third wire and the number of third wires.

[0013] The processed product is made by using (processing) the above wire rod.

[0014] Wire is strong, resistant to plastic deformation, and capable of small and complex deformations. It can be easily transformed into the shape intended by the creator, and the twist is resistant to fraying even when deformed. Furthermore, processed products using wire are stronger and have higher aesthetic appeal and commercial value than those using paper wire.

Fig. 4 is a side view showing a wire rod from which a portion of a second wire rod and a third wire rod has been peeled off. Fig. 5 is a plan view showing a coaster, which is a processed product made using wire rod. Fig. 6 is a plan view showing a basket, which is a processed product made using wire rod. Fig. 7 is a perspective view showing a basket, which is a processed product made using wire rod. Fig. 8 is a perspective view showing an ornament, which is a processed product made using wire rod.

[0016] 1 to 3, a wire 1 includes an intermediate wire 2 and a third wire 30. The intermediate wire 2 and the third wire 30 are made of a tungsten carbide, and the third wire 30 is made of a tungsten carbide.

[0017] 2 and 3, the intermediate wire 2 is formed by twisting one or more second wires 20 around the outer periphery of a first wire 10. In addition, one or more third wires 30 are twisted around the outer periphery of the intermediate wire 2. The twist pitch P2 of the second wires 20 is longer than the twist pitch P3 of the third wires 30.

[0018] The twist direction of the second wire rod 20 and the third wire rod 30 may be clockwise or counterclockwise. The twist direction of the second wire rod 20 and the third wire rod 30 may be the same or different. By twisting multiple second wire rods 20 and multiple third wire rods 30, the twist becomes less likely to fray when the wire rod 1 is deformed, such as by bending.

[0019] The first wire rod 10, the second wire rod 20, and the third wire rod 30 are made of soft metals. Examples of soft metals include precious metals such as gold, silver, and platinum, aluminum, brass, copper, and alloys thereof. All or two of the first wire rod 10, the second wire rod 20, and the third wire rod 30 may be made of the same metal, or they may be made of different metals.

[0020] When producing a processed product including a deformed wire 1, such as a mizuhiki craft using the wire 1 described below, the diameters of the first wire 10, the second wire 20, and the third wire 30 are preferably 0.05 mm to 0.50 mm, and more preferably 0.10 mm to 0.30 mm. All or two of the diameters of the first wire 10, the second wire 20, and the third wire 30 may be the same or different from each other.

[0021] The twist pitch P3 of the third wire 30 is preferably 0.5 to 1.5 times the product (=φN) of the diameter φ of the third wire 30 and the number N of the third wire 30, and more preferably 0.8 to 1.5 times the product (=φN) of the diameter φ of the third wire 30 and the number N of the third wire 30. The twist pitch P2 of the second wire 20 is preferably 1.0 to 5.0 times the twist pitch P3 of the third wire 30, and more preferably 2.0 to 4.0 times. These numerical ranges make the wire 1 easier to deform (process) such as by bending, and also make the twist less likely to fray when the wire 1 is deformed.

[0022] Next, an embodiment of the wire 1 will be described. As shown in FIGS. 2 and 3 , the intermediate wire 2 has six second wires 20 twisted in a counterclockwise spiral around the outer periphery of the first wire 10. As shown in FIGS. 2 and 3 , six third wires 30 twisted in a counterclockwise spiral around the outer periphery of the intermediate wire 2 (the outer periphery of the second wire 20). The first wire 10, the second wire 20, and the third wire 30 are all linear members with circular cross sections and made of silver. The diameters of the first wire 10, the second wire 20, and the third wire 30 are all 0.12 m. The twist pitch P2 of the second wire 20 is 1.63 mm. The twist pitch P3 of the third wire 30 is 0.66 mm. The twist pitch P2 of the second wire rod 20 is 2.50 times the twist pitch P3 of the third wire rod 30. The twist pitch P3 of the third wire rod 30 is 0.92 times the product of the diameter φ of the third wire rod 30 and the number N of the third wire rods 30 (=φN).

[0023] The processed product is made using only the wire rod 1 or the wire rod 1 together with other materials. The processed product is not particularly limited, but may be, for example, an art piece, an ornament, or tableware. The processed product is made by bending, knotting, braiding, or binding the wire rod 1.

[0024] 4 shows an example of a processed product using the wire rod 1, which is a coaster 100 (rug) made by knotting (braiding) a plurality of aligned wire rods 1. This coaster 100 is made using a knotting (braiding) method called Ume Musubi, which is a Mizuhiki craft technique.

[0025] 5 and 6 show an example of a processed product using the wire rod 1, which is a basket 200 made by knotting (weaving) a plurality of wire rods 1 multiple times. This basket 200 is made by a knotting (weaving) method called Awaji knot, which is a technique of Mizuhiki crafts.

[0026] 7 shows an example of a processed product using the wire 1, which is a turtle figurine 300 made by bending, knotting (braiding), and tying a plurality of wires 1. This figurine 300 is also made using the Mizuhiki craft technique.

[0027] The deformation of the wire 1 is not limited to bending, knotting (braiding) and binding, but may be other deformations. The above-mentioned processed products are made by a craftsman using the Mizuhiki craft technique, but they may be made by a technique other than Mizuhiki craft, or may be made by a machine or device.

[0028] The wire 1 comprises an intermediate wire 2 in which one or more second wires 20 made of a soft metal are twisted around the outer periphery of a first wire 10 made of a soft metal, and one or more third wires 30 made of a soft metal, with the third wires 30 twisted around the outer periphery of the intermediate wire 2, and the twist pitch P2 of the second wires 20 is longer than the twist pitch P3 of the third wires 30. As a result, the wire 1 is strong, resistant to plastic deformation, easily capable of small and complex deformation, easily deformed into the shape intended by the manufacturer, and even if deformed, the twists of the second wires 20 and the third wires 30 are unlikely to fray. Furthermore, even if the wire 1 is slightly bent in part, the bend can be easily corrected by pulling on both sides.

[0029] Furthermore, processed products using this wire 1 are stronger than processed products using paper wire, and their glossy appearance makes them more aesthetically pleasing and increases their commercial value. Furthermore, since the portion of the processed product made of wire 1 is soft, the portion made of wire 1 can be deformed from its original shape according to preference and application. For example, if the processed product made of wire 1 is a basket 200, it can be freely deformed from its original shape shown in Figures 5 and 6 by applying an external force.

[0030] Furthermore, by forming the first wire rod 10, the second wire rod 20, and the third wire rod 30 from precious metals, the wire rod 1 shines beautifully, coupled with the twisting of the second wire rod 20 and the third wire rod 30. Furthermore, processed products using this wire rod 1 shine beautifully, and have higher aesthetic appeal and commercial value.

[0031] The wire 1 can be more easily deformed into finer or more complex shapes by setting the diameters of the first wire 10, the second wire 20, and the third wire 30 to 0.05 mm to 0.50 mm, more preferably 0.10 mm to 0.30 mm. In addition, the wire 1 can be more easily deformed into the shape intended by the manufacturer.

[0032] The wire 1 can be more easily deformed into finer or more complex shapes by setting the twist pitch P3 of the third wires 30 to 0.5 to 1.5 times the product (=φN) of the diameter φ of the third wires 30 and the number N of the third wires 30, more preferably 0.8 to 1.2 times the product (=φN) of the diameter φ of the third wires 30 and the number N of the third wires 30. Furthermore, the wire 1 can be more easily deformed into the shape intended by the manufacturer. Furthermore, the twist of the second wires 20 and the third wires 30 in the wire 1 is even less likely to fray even when deformed.

[0033] The wire 1 can be more easily deformed into finer or more complex shapes by setting the twist pitch P2 of the second wire 20 to 1.0 to 5.0 times, more preferably 2.0 to 4.0 times, the twist pitch P3 of the third wire 30. Furthermore, the wire 1 can be more easily deformed into the shape intended by the manufacturer. Furthermore, the twists of the second wire 20 and the third wire 30 in the wire 1 are even less likely to fray even when the wire 1 is deformed.

[0034] The present invention is not particularly limited to the above-described embodiment, and can be modified as appropriate within the scope of the gist of the present invention.
