Summary of the Invention
Problems to be Solved by the Invention
[0004] Patent Document 1 has a winding type rope structure which is troublesome to stretch. Patent Document 2 is bulky with a metal clip. Patent Document 3 uses a band that can be wound up and paid out. Patent Document 4 uses a flexible wire and a cylindrical rubber bush, and the document does not solve the elongation problem. Patent Document 5 has a multi-functional grip, and the document does not solve the elongation problem. Patent document 6 uses a fitting for connecting air tubes, and the document does not address the issue of elongation. Patent Document 7 describes a structure that includes a connecting fitting that irremoves a screw terminal provided at the left end of the wire and holds the wire in a ring shape, but it is cumbersome to remove when it is hanging from a belt. [Means for solving the problem]
[0005] Because it is made of twisted elastic rubber cord, keys can be securely inserted, will not fall off even with vibration or contact with the body, can hold multiple keys, can be suspended from a belt or similar, allowing keys to be easily seen from the outside, and is more durable than plain rubber. [Effects of the Invention]
[0006] As mentioned above, it can be hung from a belt or similar item, allowing you to visually check the number of keys, easily remove or attach keys, and even attach golf tees when playing golf. Furthermore, it has a simple appearance. [Brief explanation of the drawing]
[0007] [Figure 1] This is a diagram of the key attachment strap of the present invention. [Modes for carrying out the invention]
[0008] Four elastic cords are twisted together, and circular rings are fixed to both ends of the cord. A carabiner is passed through the rings, one end is threaded through a belt, and a key is passed through the carabiner at the other end to secure it. [Examples]
[0009] Circular rings 2 are passed through both ends of the twisted cord 1, a carabiner 2 is passed through the circular rings, and one end is attached to a belt and the other end is attached to a key 4. [Explanation of symbols]
