Abstract

(57) [Abstract] (With correction) [Problem] Since a conventional cord joint cannot be integrated and bent when joined, the string becomes rigid by the length of the joined joint, and the string is hung on the neck. In such a case, the joint does not conform to the roundness of the neck, causing a sense of incongruity, and the joint can be easily separated when pulled along a straight line in the axial direction of the joint. Since the tension does not coincide with the axial direction of the joint, the joint is difficult to separate, and has not sufficiently responded to the purpose of safety. SOLUTION: A ring 4 is formed on one of a pair of halves forming a joint, and a ring 5 having a cut 6 at a front end portion is formed on the other half, and the ring of the one half is formed. The engagement and disengagement of the two wheels are performed by pushing the gap of the other half of the wheel.

Description

[Detailed description of the invention]     [0001]   [Technical field to which the invention belongs]   In the present invention, a string or a rope is used to secure the safety when the force is applied. About the hand. For example, when hanging a name tag or decoration by hanging a looped string on the neck, If it is caught or pulled, the neck will be tight and dangerous. Occasionally, the looped string joints separate to release the tension.     [0002]   [Prior art]   Conventionally, a joint as shown in FIG. 3 has been provided for the above-described purpose. In this figure As shown, the joint consists of two parts 1, 2 each attached to one end of a string 3 Be killed. Each half 1 and 2 of the joint is hollow and has a split groove 4 in the axial direction. The split grooves allow each of the halves 1, 2 of the joint to elastically expand or contract. Each half of the joint has a front end fitted in a lantern lid style. Since the groove 5 is formed on the inner circumference on the side to be formed and the ridge 6 is formed on the outer side on the outer side, When the halves 1 and 2 are fitted, the groove 5 and the ridge 6 are engaged and connected. String 3 Make a knot at the end by passing it through the halves 1 and 2 so that it does not come off. String 3 both , The joint halves 1 and 2 are separated and the loop of the string is opened.     [0003]   [Problems to be solved by the invention]   Although the above is an example of the related art, what is common to the related art is a two-piece joint. When the hands are joined, they become one rigid body and have no freedom of bending, so the length of the joint The string becomes rigid by that much. For this reason, when the string is straightened and pulled, the joint If it comes off, but the loop of the string is hung on the neck, the joint does not conform to the roundness of the neck In addition to the unpleasant feeling, even if tension is applied to the string, the tension matches the axial direction of the joint. Therefore, there was a problem that the joint was hard to come off, and the purpose of safety could not be achieved.   Thus, the present invention provides a lace joint in which the axis of the merged joint is flexible. Things.     [0004]   [Means for Solving the Problems]   One of the joints has a loop at the front end and the other has a truncated loop at the front end, The thickness of the ring at one front end of the joint is larger than the width of the cut at the other front end of the joint. A cord joint characterized by being combed. Make a cut in both rings Is also good.     [0005]   [Embodiment of the invention]   FIG. 1 shows an embodiment of the present invention. The string joint consists of two parts 1,2. Called joint half I will do it. Each joint half is attached to the end of the string 3. This installation is optional, For example, the end of the string 3 is embedded by insert molding at the time of half molding. Or the string is a flat string At times, leave the base of each half 1 and 2 hollow, insert a vertical split groove at the end of the cord An umbrella ball may be made and the strap may be slid into the base from this split groove. Attach the joint halves 1 and 2 to both ends of one string and engage the joint halves to form a string loop. You do it.     [0006]   The joint half 1 has a ring 4 at the front end. The other joint half 2 also has a ring 5 at the front end. Although formed, the loop has a cut 6 at the front end. The width of this cut is one side Is smaller than the thickness of the ring 4 of the joint half 1 of FIG. A cut of the ring 5 as shown enlarged in FIG. The opposite ends of the eyes 6 are rounded so that the joint halves 1, 2 In order to join the ring 4, the ring 4 is pressed so that the gap 6 of the other You can put it inside. Conversely, when tension is applied to the joined joint, the wheel 4 is cut off the wheel 5. The eyelet 6 is elastically pushed open and comes off the ring 5.     [0007]   The above-mentioned cut 6 at the tip of the wheel 5 does not necessarily need to be open. Figure 2 Several other embodiments of the idea are illustrated. FIG. 2A shows a shape in which the outside of the cut 6 of the ring 5 is open. The cross section of the ring 4 for this is round on the outside and triangular on the inside, and each joint half 1 , 2 are joined, the ring 5 pushes open the cut 6 of the ring 4 and the joint is released. When the inner edge of the wheel 4 is cut, the edge of the wheel 5 is widened by the wedge action. You.     [0008]   In the example of FIG. 2B, when a flat string is used as the string 3, the rings of the joint are orthogonal to each other. In order to prevent the cord from being twisted slightly, the joint halves 1 and 2 are also provided with bases 1a and 2a. The rings 4 and 5 are formed in a slightly twisted state with respect to the base. Then, the faces of the two rings 4 and 5 cross each other, but the string 3 remains flat.     [0009]   In the example of FIG. 2C, the joint halves 1 and 2 have exactly the same figure of eight, and are cut into one ring of the figure eight. A grid 6 is provided. Pass one end of the cord 3 through the unbroken loop of the joint half 1 Turn it over, heat solidify it or attach it to the joint half 1 and attach the other end of the string 3 to the other To the joint half 1 through the loop with the cut 6 of the joint half 2 (same shape as 1) Attach to the joint half 2 in the same manner as described above. The operation is the same as in each of the above examples.   In the example of C, a cut 6 may be made in both rings of the figure 8 joint half. Then, when attaching the joint half to the string, there is no need to worry about the orientation of the half.     [0010]   [Effect of the invention]   The string joint of the present invention has a shape in which two rings are joined in a chain, so it is easy to engage and disengage. And can be bent freely, and the shape is simple, so the production is cheap I can do it.
