Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, a portable radio,
The present invention relates to a hand strap for a hanging string attached to a suspended body such as a mobile phone, other various devices, and a handbag. 2. Description of the Related Art As shown in FIG. 8, a conventional hand strap includes a thin string belt 10 for attachment which is attached to a suspended body such as a camera and a thick string which is attached to a wrist. Each of the belts 20 is folded in two, and both ends thereof are integrally joined to each other, and a joint 30 made of synthetic resin or metal is fastened to the joint 21. In addition, a molded article is used as a connecting tool made of a synthetic resin, and a method of molding with a joint portion facing between molding dies is used. [0003] However, the above-mentioned conventional hand strap has the following disadvantages. [0004] When using an ultrasonic welding method or a heat welding method for joining the thick string belt and the thin string belt, a special machine is required, and a large cost is required for equipment cost and operation cost. In the case where the connecting tool is molded into the joint by insert molding, a special machine and equipment for insert molding are required, which requires a large amount of time and labor, thereby increasing the processing cost. Since the thick string belt and the thin string belt are joined to each other by welding or bonding, the joining is likely to be uneven and may be detached. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to join a thick string belt and a thin string belt with each other at their ends. A simple and reliable connection can be achieved without the need for a special machine, and an excellent quality hand strap can be provided easily and inexpensively without the need for insert molding. It is assumed that. [0006] In order to achieve the above object, a hand strap according to the present invention comprises a wrist attached to a thin strap belt 1 for attaching to a suspended body such as a camera. A hand strap comprising a strap thick belt 2 made of a thick string hung on the side, wherein the strap thick string belt 2 is formed in a flat bag shape and has a hollow interior sufficiently larger than the length of the thick strap 2. The long thin belt 1 is inserted and its both ends are tied, and the knot 3 of the thin belt 1 is shifted into the bag of the thick belt so that both ends of the thick belt 2 are joined and fixed so as to be vertically overlapped. A stopper 4 is provided at the both ends of the cord belt 2 so as to cover the joined portion. An embodiment will be described with reference to the drawings and the like. 1 and 2 show a hand strap according to the present invention. As shown in FIG. 1, the attaching thin string belt 1, the strap thick string belt 2, and the stopper 4 fixed between the belts.
And As shown in FIGS. 6 and 7, the strap thick cord belt 2 is formed by folding a flat bag-shaped belt of a fixed length into a U-shape from the middle and is usually used as a braid or the like. In addition to being formed by sack weaving, two strips of a certain width are stacked and sewn on both sides, or a wide one is folded up in parallel in the width direction to make it double, and one side is sewn and sewn. Make a string. Both ends of the thick cord belt 2 have openings 2a. 2b. The fine string belt 1 is made of a thin and strong string having a round or square cross section, and is sufficiently longer than the length of the thick string belt 2. This thin string belt 1 can also use a braid usually called a pine string. The stop 4 is shown in FIG. FIG. As shown in FIG. 5, it may be formed in a flat rectangular tube shape made of a synthetic resin molded product. FIG. As shown in FIG. 4, it is also possible to bend a metal plate piece and wind it around a joining portion between a thick string belt and a thin string belt to caulk. As shown in FIG. 6, the thin string belt 1 is inserted through the opening 2a (or 2b) at the end of the strap thick string 2 and pulled out from the other opening 2b (or 2a). And tie them together to make knot 3. Knot 3 can be tightly tied and difficult to untie when figure 8 tied. Since the thin cord belt 1 is loosely inserted into the thick cord belt 2 of the bag strap, the cord strap freely moves when pulled. For this reason, one is pulled to move the knot 3 into the bag of the thick cord belt 2 as shown in FIG. Next, both ends of the thick cord belt 2 are aligned so as to be vertically overlapped, and the overlapped portion is joined with an adhesive to be integrated.
Alternatively, sewing is performed by sewing instead of the adhesive. Then, as shown in FIG. 5, the narrow string belt 1 formed in a ring shape protrudes from both ends of the thick string belt 2 in a coupled state. The stopper 4 is inserted from the end of the thin cord belt 1 and locked at the stepped portion to the thick cord belt 2. Then, an adhesive is applied in order to fix immovably. In the case of a stopper made of a metal plate piece, the stopper is integrally fixed when the stopper is applied to the joint and rolled from the left and right and swaged. According to the present invention, as described above, the strap thick string belt 2 is formed in a flat bag shape, and the thin string belt 1 sufficiently longer than the length of the thick strap belt 2 is inserted into the hollow inside thereof. Then, the knot 3 of the thin string belt 1 is shifted into the bag of the thick string belt, and the both ends of the thick string belt 2 are joined and fixed so as to be vertically overlapped. Since the stopper 4 is provided in the portion so as to cover the thin belt, the thin belt inserted into the bag of the thick belt becomes a core, and the thin belt is an endless loop, so that There is no joint with the thick string belt, so it does not come off even under strong tension, and it does not require insert molding, so no special machine is required, so it is easy to manufacture by hand To significantly reduce costs There is a point. In addition, since there is no need for processing that may cause variations such as ultrasonic welding or heat fusion at the time of joining the thick string belt and the thin string belt, there is no strong variation and a high quality excellent product is provided at low cost. it can.
