Hereinafter, the present invention will be described in detail according to examples.

The present invention relates to a wire lock as disclosed in Figure 1, the present invention is a key body to be detachable by the key body 110 and the opening and closing means 112 provided with an opening and closing means 112, as shown A key bundle 100 made of a clasp block 120 that is bound to 110, and both ends include a wire 200 connected to the key body 110 and the clasp block 120 of the key bundle 10, respectively. It is done by doing. 2 is a photograph showing the parts constituting the present embodiment, and FIG. 3 is a photograph showing the core material 210 of the present embodiment.

Since the key bundle 100 is known, a detailed description thereof will be omitted. In this embodiment, the key bundle 100 has been illustrated to be made of a dial key, but it is natural that the key bundle 100 is not limited to such a dial key.

The wire 200 is made of a core material 210 and a shell 220 that protects the core material 210 by inserting the core material 210. The core member 210 is formed by winding a thread (fiber) several times in a skein shape, and the core member 210 is composed of a tensioning portion 212 and a plurality of non-tensile portions, as disclosed in FIG. 3. The tensile part 212 is formed to have the same length as the length of the core material 210 and is a part that is tensioned in the longitudinal direction when the core material 210 is pulled in the longitudinal direction, and the non-tensile part is less than the length of the core material 210. It is formed long so that when the core material 212 is pulled in the longitudinal direction, it is not tensioned in the longitudinal direction and remains in a loose state.The non-tensile part is made of first, second, and third non-tensile parts (214, 216, 218) with different lengths. .

In this way, as the non-tensile portion is formed in the core material 210, the wire cannot be easily cut at once, as described later. That is, when cutting the wire with scissors, tension is applied to the wire so that the wire must be pulled taut to a certain extent to cut the wire well.As described above, the first, second, and third non-tensile portions (214, 216, 218) on the core member 210 Since is formed, when the core member 210 is pulled and cut in the longitudinal direction, only the tensile portion 212 of the core member 210 is cut, and the first, second, and third non-tensile portions 214, 216, 218 are not cut. Therefore, in order to completely cut the core material 210, the tensile part 212 is cut, and then the first non-tensile part 214 is cut by pulling the core material 210 so that the first non-tensile part 214 becomes taut, and then the first non-tensile part 214 is cut again. 2 It is not easy to cut the core material 210 because it is difficult to cut the core material 210 and it takes a lot of time because the non-tensile part 216 needs to undergo several cutting processes such as cutting the second non-tensile part 216 by pulling the core material 110 so as to become taut. .

Preferably, the right and left ends of the core material 210 are provided with binding means for binding the threads (fibers) so that the threads (fibers) forming the core material 210 are not disturbed. In this embodiment, the threads (fibers) are bound so that the threads (fibers) forming the core material 210 are not disturbed by the ring 230 as disclosed in FIG. 2. And by this ring 230, the wire 200 is connected to the key bundle 100. Reference numeral 240 is a fixing pin for fixing the wire to the key bundle 100.

On the other hand, the outer shell 220 is to protect the core material 210, consisting of a tube having a length corresponding to the core material 210, the core material 210 is inserted inside, the outer shell 220 is the core material 210 and It is made of a braided tube made of synthetic fibers so that they can be bent freely together. In this embodiment, it was illustrated that a separate mesothelial 222 is inserted into the outer skin 220 and a core material 210 is inserted into the mesothelial 222, in this case, a braided tube formed of a material that can complement each other's strengths and weaknesses. The middle skin 222 and the outer skin 220 are used.

The core material 210 is inserted into the outer shell 220 to form a wire 200, preferably by inserting a traction tool such as a wire into the outer shell 220 and connecting the core material 210 to the end of the traction tool. By pulling the traction mechanism, the core material 210 can be easily inserted into the shell 220.

Wire 200 having such a configuration has both ends are coupled to the key body 110 and the clasp block 120 of the key bundle 100, respectively. As described above, both ends of the wire 200 are key bundles ( Inserted into the fitting grooves respectively formed in the key body 110 and the clasp block 120 of 100), and the fixing pin 240 is inserted across the fitting groove to fix the wire 200 to the key bundle 100, The fixing pin 240 is fitted so as to pass through the ring 230 coupled to the outer shell 220 and the core 210 of the wire 200 so that the outer shell 220 and the core 210 are also bound. Since it is a known method to couple the wire 230 in this manner using the fixing pin 240, a more detailed description thereof will be omitted. 4 is a photograph showing the end of the wire 200 of this embodiment.

Hereinafter, a method of manufacturing the core member 210 according to the present embodiment will be described.

The core material 210 is manufactured by using a separate winding mechanism 10, the winding mechanism 10, as shown in Figure 5, a plurality of pins protruding from the left and right rectangular substrate 12 The pins are formed in the length direction of the substrate 12 at a predetermined interval between the first and second winding pins 13 and 14 and the first and second winding pins 13 and 14 , 2 winding pins (13, 14) and the first, 2, 3 via pins (15, 16, 17) which are positioned to gradually move away.

A core material 210 is made by winding a thread (fiber) in the winding mechanism 10 having such a configuration in a process as shown in FIG. 6. Figure 6 is shown to be wound one by one thread (fiber) on each of the winding pin and the passing pin to aid understanding, in practice, as described later, the core material 210 to have the required level of strength and thickness. The core material 210 is made by repeatedly winding the thread once. First, the yarn (fiber) is wound around the first and second winding pins (13, 14). Preferably, a loop is made at the end of the thread (fiber), and the loop is hung on the first winding pin (13), Do not loosen the end of ).

After winding the thread (fiber) around the first and second winding pins (13, 14) about 3 to 5 times, the first and second winding pins (13, 14) so that the thread (fiber) passes through the first through pin (15). ) To 3~5 times. Then, the thread (fiber) is wound around the first and second winding pins 13 and 14 about 3 to 5 times so that the thread (fiber) passes through the second via pin 16, and then the thread is wound around the third via pin 17. The first and second winding pins 13 and 14 are wound around 3 to 5 times to pass through to make a bundle of threads, that is, the core material 210.

When the yarn (fiber) is wound in this way, the portion wound so as to pass through the first and second winding pins (13, 14) of the yarn (fiber) forms the tensioning portion 212, and passes through the first via pin (15). The part wound so as to be longer than the tension part 212 forms the first non-tensile part 214, and the part wound so as to pass through the second via pin 16 is longer than the first non-tensile part 214 It is formed to form a second non-tensile portion 216, and the portion wound so as to pass through the third via pin 17 is formed to be longer than the second non-tension portion 216 to form a third non-tension portion 218. 7 is a photograph showing a state in which a thread (fiber) is wound around the winding mechanism 10 to make the core material 210 of FIG. 3.

As described above, a core material 210 is formed by winding a thread (fiber), and a ring 230 is connected to the left and right ends of the core material 210 so that the threads (fibers) are not disturbed. Unite.

When making the core material 210 by winding the thread (fiber) on the winding mechanism 10 as described above, if the core material 210 is made by winding a relatively large number of times using a fine thread (fiber), as will be described later, scissors It is good that the wire is not easily cut when the wire is cut with a etc., but in this case, since the number of windings of the thread (fiber) increases, there is a concern that productivity decreases accordingly. Therefore, in consideration of these points, the thickness and number of windings of the used yarn (fiber) are properly adjusted. The core material 210 disclosed in FIGS. 3 and 7 is illustrated as being manufactured by sequentially using high-strength PE fibers and aramid fibers in order to improve the strength of the core material 210 and impart non-flammability. In addition, in the case of making the core material 210 in this way, since the length of the core material 210 is determined by the interval between the second and second winding pins 13 and 14, the length of the core material 210 to be manufactured, that is, The core material 210 is made by adjusting the spacing of the first and second winding pins 13 and 14 according to the length of the wire 200.

On the other hand, the first, second, and third pass through pins 15, 16, and 17 of the take-up mechanism 10 are positioned to be shifted left and right, as shown, in this way, the first, second, and third pass through pins 15, 16 When the ,17) are positioned to be shifted from side to side, it is convenient to wind the yarn (fiber) without interfering with the other via pins when winding the yarn (fiber) through the respective via pins.

In the present invention having the above configuration, in particular, the core material 210 of the wire 200 is made by winding the thread in several layers, but the core material 210 is the tensioning part 212 and the first, second, and third non-tensile parts ( Since it is formed of 214, 216, 218, the core material 212 is not easily cut at once. In order to cut the wire 200 of the present invention, the wire 200 is stretched in the longitudinal direction to cut the outer shell 220 and the tension part 212 of the core material 210 first, and then pull the wire 200 again to The first non-tensile part 214 is cut by pulling the first non-tensile part 214 of 210, and the second non-tensile part 216 is tensioned by pulling the wire 200 again. After cutting, the third non-tensile portion 218 must be repeated several times. Therefore, if the bicycle or the like is locked with the present invention, there is little fear of the bicycle or the like being stolen, and the bicycle or the like can be safely stored.

In addition, in the present invention, the core material 210 is made of a bundle of yarns (fibers), and the outer shell 220 is also made of a braided tube knitted with fibers, so that the wire 200 is flexible and has no elastic force, so that the wire 200 is folded or If rolled up, it will not be unfolded by the elasticity. Therefore, it is easy to be folded or rolled to occupy a small volume, and it is easy to carry because it is lightweight.

In the above, it has been illustrated that the core material 210 is formed by winding threads (fibers) several times, but in some cases, the core material 210 may be manufactured by overlapping several threads having a predetermined length. In this case, prepare threads (fibers) having a length corresponding to the core material 210 to be manufactured, and threads (fibers) that are longer than the length of the core material 210 to be manufactured, and the threads (fibers) are left and right. The core material 210 is made by overlapping the ends so that both ends are aligned and binding the ends using a tool such as a rubber band or a ring. In this case, threads (fibers) having a length corresponding to the core member 210 form the tensioning portion 212, and threads (fibers) longer than the length of the core member 210 form the non-tensile portion.
