Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hand strap for a hanging strap that is attached to a suspended object such as a small camera, a mobile phone, various other devices and a carrying bag.

[0002]

[Prior art]

 The conventional hand strap shown in FIG. 5 is generally used. The strap shown in FIG. 4 is formed by folding a thin string body 10 attached to a suspended object such as a camera and a wide band string body 20 to be worn around the wrist into two parts, and joining them with a synthetic resin. Alternatively, the fastener 30 made of metal is put on and fastened. The thin cord 10 is made by aligning both ends and sandwiching it between the insides of both ends of the cord 20 and adhering or stitching it together to form one body, and then fastening the fasteners 30 and crimping.

Further, as the fastener 30, a synthetic resin molded product is used and a method in which a joint is exposed to the inside of the forming dies and molding is performed.

[0004]

[Problems to be solved by the device]

 However, the conventional hand strap described above has the following problems.

Ultrasonic welding or heat fusion method is often used for joining the cord and the thin cord, and therefore a special machine or facility is required, resulting in a large amount of facility cost, work cost, etc. It depends. Also, a special strap material is required. When the fastener is molded into the strap joint by insert molding, mechanical equipment for insert molding is required, which requires a large amount of work, is time-consuming, and is expensive. Since both ends of the thin cord are only sandwiched between the ends of the cord by the tip, they may come off if pulled strongly, and if there are variations in the joint, they may come off or come off easily. There is.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to join a band cord and a thin cord by a simple method and then once bond them. There is no danger of accidentally coming off or pulling out, and we will try to provide a high quality hand strap easily and inexpensively without using any means that requires large equipment such as ultrasonic waves and heat fusion. It is a thing.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the hand strap according to the present invention has a wide strap strap cord 2 to be hung on the wrist side to a mounting strap 1 made of a strap attached to a suspended object such as a camera. Is a hand strap in which a strap 3 and a stopper 3 are fitted to the joint portion, and each of the attaching strap 1 and the strap strap 2 is folded in two, and the strap 2 has an insertion hole 2a at its free end. ． The free end portion of the thin cord body is inserted into 2b and is tied inside the free end portion of the thin cord body and the free end portion of the strap body, and the knot is clamped between the free ends of the strap body. The strap, the strap, and the fastener 3 are integrally fixed.

[0008]

【Example】

 Examples will be described with reference to the drawings.

1 to 2 show a hand strap according to the present invention. As shown in the figure, it comprises a thin strap body 1 for attachment, a wide strap strap body 2 and a stopper 3 fitted to a joint portion of both strap bodies 1.2.

The thin cord 1 is composed of a thin and tough string having a round or prismatic cross section and being capable of flexing freely.

The strap strap body 2 is made of leather, a thick belt having a width such as a vinyl tape, a belt-like cloth, a flat strap used as a braid, or a bag-woven one. To be

The stopper 3 is shown in FIG. As shown in FIG. 3, it is formed as a flat rectangular tube made of synthetic resin and has an insertion opening 3a for the thin cord 1 at the front end and an insertion opening 3b for the strap 2 at the rear end. , Both insertion ports 3a. 3b communicate with each other and have a tunnel hole 3c.

Further, as shown in FIG. 4, it is also possible to bend a metal plate piece and wind the metal plate piece around the joint portion of the cord 2 and the thin cord 1 to be caulked.

[0014]

[Action]

 The hand strap of the present invention is assembled using the above parts as follows.

As shown in FIG. 3, the cord 2 is folded in two and the thin cord 1 is inserted from the outer surface of both ends to the inner surface side. Holes 2a for inserting a thin string are previously formed at both ends of the band 2. 2b is provided and this hole is used. Alternatively, a guide needle or the like may be used for piercing.

Both ends of the thin cord 1 have insertion holes 2a. Pull out from 2b and arrange, and make a knot 1a as shown in FIG. If the knot 1a is formed into a figure-8 knot, it will be difficult to untie and will become strong. A stopper 3 is inserted from the side of the other end 1b of the thin cord body 1 and fitted on the joint portion of both cord bodies 1.2, and a liquid instantaneous adhesive is applied to this joint portion. . The adhesive is applied by inserting the insertion hole 3a. It may be injected from 3b, or it may be injected directly into the overlapping portion on both ends of the strap 2 and its peripheral surface before the stopper 3 is inserted. When the adhesive is dried and solidified, as shown in FIG. 2, the joint portion between the thin cord 1 and the strap 2 is fixed to the three members while being fitted into the stopper 3. The above adhesive may not use it.

[0017]

[Effect of device]

 As described above, the present invention folds the attaching thin cord body 1 and the strap cord body 2 in two, and inserts the insertion holes 2a. The free end of the thin cord is inserted into 2b and tied inside the free end of the thin cord and the free end of the cord, and the knot is clamped between the free ends of the cord. Since the strap, the strap, and the fastener 3 are integrally fixed to each other, the thin strap 1 is irremovably coupled to the strap 2 with the knot 1a. By applying an adhesive, the knot 1a is sandwiched between both ends of the strap, and is completely and integrally fixed, so that there is no possibility that a part will come off or both straps will come off. In addition, it requires no special machinery or equipment, and can be assembled easily and cheaply by hand, and the cost can be greatly reduced compared to conventional products.
