Abstract

PURPOSE: To facilitate the manufacture of a strap by joining the overlapped terminal parts of the strap and a slim string through metal staples of a stapler, etc., and covering this joint part with a cap. CONSTITUTION: The terminal parts of a thin string 34 for attachment on the side of a camera and a thick string 32 for hang are overlapped and joined by metal staples 36 of the stapler, etc., and this joint part is covered with a cap 38. Then, tensile force in opposite directions is generated on the strap 32 and the thin string 34 in case of use and both the bent terminal parts of the metal staple 36 tries to rise but since these terminal parts are pressed on both the sides of the cap 38, they can not rise. Then, the joint part of the strap 32 and the thin string 34 is strongly linked through the metal staple 36 to the cap 38. Thus, the strap can be easily and inexpensively manufactured.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a strap used for a camera, etc., and particularly to a strap in which a thin string for attachment to the camera side is connected to a hanging strap, and a method for manufacturing the same. Regarding.

[Conventional technology]

2. Description of the Related Art Conventionally, a strap for a camera or the like has generally been provided with a metal fitting at the end of the strap, and is secured to a stopper protruding toward the camera via the metal fitting. However, those using metal fittings have the disadvantage that they are easily damaged and the cost of the metal fittings is high. For this reason, some devices have a thin string attached to the camera side attached to the end of the hanging strap, and the strap is attached to a stopper on the camera side via this thin string. In this case, the end of the strap and the thin string are joined by a process of overlapping both ends of the strap and the thin string along the longitudinal direction, temporarily securing the overlapped portion with adhesive, and sewing it together using an industrial sewing machine. required.

[Problem that the invention seeks to solve]

However, this method requires temporary fixing with adhesive. In addition, care must be taken not to overlap other strings until the adhesive dries, and the next step of sewing cannot be performed. For this reason, there is a problem in that it takes a lot of time to manufacture the strap, reducing work efficiency.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a strap and a method for manufacturing the same that can easily connect the strap and a thin string.

[Means for solving problems]

In order to achieve the above object, the strap according to the present invention has the ends of a narrow first string for attachment to the camera and a wide second string for hanging overlapped in the longitudinal direction. They are characterized in that they are joined with a metal needle in the matched state, and the engaging part is covered with a cap that fits into the joined part.

In order to achieve the above-mentioned object, the method for manufacturing a strap according to the present invention has the following features: The method is characterized by the following steps: bending and fixing the metal needles while stacking them in the same direction, and covering the joints fixed with the metal needles with a cap.

[Effect]

According to the strap and its manufacturing method of the present invention, the wide second string and the narrow first string are connected by a metal needle, and the cap is further fitted into the connected portion. This cap prevents the metal needle from coming off even if a tensile force is applied to the joint.

Therefore, the thin string and the strap can be joined without temporarily fixing them with adhesive.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a strap and a method for manufacturing the same according to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, the main body 12 of the camera 10 is equipped with a photographic lens 14, a shutter button 16, a finder 18, and a strobe 20, and the side of the camera has a stopper 22 for attaching a strap. . At the end of the large set (hereinafter simply referred to as a strap) 32, there is a thin string 34 for attaching to the camera side.
are connected, and the stopper 2 on the camera side is connected via this thin string 34.
It is attached to 2. That is, the ring-shaped tip of the thin string 34 is inserted into the stopper 22, and the end of the strap 32 opposite to the thin string 34 is passed through the inserted ring-shaped tip, thereby attaching the strap 32 to the stopper 22.

Next, FIGS. 2 to 4 show a method of connecting the strap 32 and the attachment cord 34.

The straps 32 are overlapped in the longitudinal direction as shown in FIGS. 2 and 3, and both ends 32A and 32A are aligned.

Next, the band-shaped thin nylon fiber string 34 having a width narrower than the width of the strap 320 is extended in the longitudinal direction so that both ends 34A, 34A sandwich both ends 32A, 32A of the strap 32. It is overlapped with 32A. By placing the thin string 34 on the outside, it can be seen whether the metal needle is reliably biting. This overlapped portion is fastened with a U-shaped metal needle 36 of a stapler, as shown in FIGS. 2 and 3. Stopped metal needle 3
6 is bent so that both parts thereof face each other as shown in FIG.

Thereby, both ends of the strap 32 and the thin string 34 are connected.

Next, as shown in FIG. 2.3, a cylindrical plastic cap 38 with a rectangular cross section to match the shape of the joint is fitted from the thin string 34 into the joint fastened with the metal needle 36. , the strap according to the present invention is completed as shown in FIG.

The operation of the strap according to the present invention constructed as described above will be explained.

The strap 32 is attached to the camera 10 using the stopper 22.
1. Next, pass the strap 32 from the opposite end through the ring-shaped tip of the thin string 34 through which the stopper 22 has been inserted, and pull the strap 32 until it reaches the state shown in FIG. be exposed.

In use, tension forces in opposite directions are generated in the strap 32 and the thin string 34, causing the bent ends of the metal needle 36 to rise. However, both ends of the metal needle 36 are held down by both sides of the cap 380 and cannot rise up. Further, both ends of the metal needle 36 that is about to rise are in contact with the inner surface of the cap 38, and the strap 32 and thin string 34
, the metal needle 36, and the cap 38 are more firmly connected.

Further, the cap 38 hides the damage caused by the metal needle hitting the camera and the joints at the cut surfaces of the strap 32 and the thin string 34, thereby giving the strap a good appearance.

Further, although no adhesive is used in this embodiment, the adhesive may be crushed into the capped joint portion. In this case, a predetermined amount of adhesive is injected into the cap, so even if it is not dried or mixed with other straps,
No adhesive will stick to it.

Further, in the embodiment, a camera has been described, but a device such as a tape recorder that requires a strap may be used.

Incidentally, as the metal needle, a strong stapler for commercial use or the like can be used.

〔Effect of the invention〕

As explained above, according to the strap according to the present invention,
The overlapped ends of the strap and the thin string are joined together with a metal needle such as a stapler, and then a cap is placed over the joined part, so that the strap can be manufactured easily and work efficiency can be improved. We can provide low-cost straps.
