Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a strap for portable goods used for portable goods such as a mobile phone and a camera, and a component thereof.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 6, for example, as shown in FIG. 6, a loop-shaped thin string (90) serving as a portable item and a thick string (91) serving as a hanging loop are resin-fused or bonded. There are known portable straps (9) and the like which are connected by sewing means and the connecting portion is fixed in a covering cover.

[0005] However, in the conventional strap for portable goods (9), thread breakage or resin hardening occurs by means of sewing or resin fusion as described above, and as a result, the connection strength is insufficient. It was difficult to secure, and an excessive load was applied, such as swinging the mobile device for a long time with the mobile device strap or separating the mobile device and the mobile device strap with a very strong force for a long time Of course, pull the thin string (90) or the thick string (91) strongly, wrap the thick string (91) around your hand, or spread the loop of the thick string (91) and hold it. In some cases, the thin string and the thick string may be detached or cut off at the connection between the thin string (90) and the thick string (91), and the portable article may fall off.

[0004] On the other hand, the strap for portable goods is used by directly attaching to the strap of portable goods. With the diversification of designs of portable goods, the design of the strap for portable goods is also increased. Preference is strongly required.

[0005] Here, by using metal parts in place of synthetic resin, synthetic fiber, etc. on the design side, it is possible to bring out a sense of quality due to the metallic luster on the design side. When metal parts are used, there is a drawback in the strength of the entire strap for portable goods.

[0006] That is, if only the thick string on the suspension side is made of a metal chain, the resin fixing means as described in the prior art will cause the resin portion to become strong when a heavy load is applied to the metal chain. Deformation or breakage may cause the metal chains to come off.

On the other hand, it is, of course, possible to use a metal chain as the thin string on the portable item side, but if a metal chain is used, the metal chain is always connected to the portable item. Since the metal chain is rubbed in the portion, for example, when the portable article is a cellular phone or the like, there is a practical disadvantage that the paint near the connecting portion is easily peeled off.

In addition, there are circumstances in which the heavy use of metal parts causes an increase in the manufacturing cost of a strap for portable goods.

[0009]

[Problems to be solved by the invention]

 The present invention has been made in view of the above circumstances, and has a sufficient strength of a connecting portion, has a high-grade design, and is economical. An object of the present invention is to provide a connection fitting for a product strap.

[0010]

[Means for Solving the Problems]

 In the portable product strap in which the connecting portion between the loop-shaped thin string portion on the portable device side and the suspending suspending portion is concealed and fixed in the covering cover, a connecting fitting is used for the connecting portion, and the connecting fitting is: A metal wire rod having a bending strength capable of withstanding a load caused by the weight of the portable article is bent to form a string tightening section for connecting to the thin string section, and a hook-shaped caulking section; The part is formed by using a metal chain or a chain element constituting the metal chain. The chain is hung on the caulking part and fixed by caulking, and the thin string part is fastened to the string tightening part of the connection fitting. By doing so, a strap for portable goods in which the thin string portion and the hanging string portion are connected and fixed via a connection fitting is used as means for solving the problem.

[0011]

[Effect of the invention]

 According to the present invention, in the portable product strap in which the thin string portion serving as the portable product side and the hanging strap portion for suspension are fixed in the covering cover, the connection fitting is a hook-shaped caulking portion made of a metal wire. And a string tying part for connecting the thin string part, the hanging string part uses a metal chain, and the hanging string part as the metal chain is formed by the caulking part. Since the thin string portion and the hanging string portion are connected and fixed by crimping and fixing the thin string portion to the string fastening portion of the connection fitting, sufficient strength of the connecting portion is provided. Thus, it is possible to prevent the connection part of the strap for portable goods from being detached, and to prevent damage to the portable goods.

[0012] The connecting fitting has a hook-shaped caulking portion made of a metal wire and a string binding portion for connecting the thin string portion, and the hanging string portion is made of a metal chain. By fixing the hanging string portion, which is a metal chain, to the caulking portion, a large difference in the strength of the material does not occur, and the covering cover is used for the string portion or the hanging portion. Since the load that pulls the string is not received by the limited engagement surface due to the mutual engagement of the members, sufficient strength is ensured, and the variety of designs is ensured by using metal materials. Thus, a high-quality strap for portable goods can be obtained.

Further, in the case where the chain element at both ends of the hanging string portion is hooked on a metal wire constituting the caulking portion of the connection fitting, and the caulking portion is bent to form a strap for portable goods, In addition, all the directions of the chain elements can be aligned in the same direction, and the appearance can be extremely improved.

Embodiments and Examples of the Invention

 FIG. 1 is an explanatory view showing a connecting structure of a strap for portable goods according to a first embodiment of the present invention, which is a partial cross section. FIG. 2 is a front view and a right side view of a connecting bracket according to the first embodiment of the present invention. 3 is an explanatory view showing a state where the connecting fitting according to the first embodiment of the present invention is crimped, FIG. 4 is an explanatory view showing a connecting structure of the strap for portable goods according to the second embodiment of the present invention, which is a partial cross section, FIG. 5 is an explanatory view showing a state where the connecting fitting according to the third embodiment of the present invention is crimped.

As shown in FIG. 1, the strap for portable goods according to the first embodiment of the present invention is connected to a thin string (4) formed into a loop on the mobile phone side via a brass fitting (1) and a suspension. A lower metal chain (2a) is connected to the lower metal chain (2a), and the connecting portion is concealed and fixed by a covering cover (3). The connecting bracket (1) is substantially U-shaped as shown in FIG. A metal wire made of brass having a shape is bent at both ends to form a symmetrical hook-shaped caulked portion (11), and a part of the metal wire is formed into a thin string portion (4). ), And the thin string (4) is ultrasonically welded with both ends aligned, and then a knot (40) is formed to reinforce the section, and the loop (4) is connected to the loop. It is wound around the string tying part (10) of the connecting bracket (1) and folded back, and one end of the loop divided by the string tying part (10) is passed through the other loop. The metal chain (2a) is a string-like body composed of a number of chain elements (20), and the chain elements (20) at both ends thereof are respectively connected to the connection fittings ( 1) Hook the metal wire in the caulked part (11) and fix the caulked part (11) of the connection fitting (1) by bending it as shown in Fig. 3 to fix and connect. The covering cover (3) is a synthetic resin molded article having a through hole (30) and an opening (31) on the opposite side thereof and having a length of about 11 mm and a width of about 8 mm. ) Is passed from the opening side to the through hole (30) to cover the connecting portion.

Accordingly, the strap for portable goods according to the first embodiment of the present invention has a shape in which the thin string (4) and the hanging chain (2a) are connected in a loop shape by the covering cover (3). Will be provided.

Further, in the first embodiment, the shape of the connection fitting (1) is not a perfect U-shape, but is a shape in which both ends, that is, the swaged portions (11) are slightly closer to each other. By doing so, the connection strength between the connection fitting (1) and the chain (2a) is further improved with respect to the load generated during suspension.

In the first embodiment, the caulking portion (11) and the knot (40) of the connection fitting (1) press the inner wall (32) of the covering cover to fix the covering cover (3). I have. The reason why the cover is not firmly fixed more than necessary is that the covering cover (3) does not directly receive the load of the connecting portion between the string (4) and the hanging string (2).

In other words, the covering cover (3) is intended to protect the cord tying portion (10) and to improve the appearance, and hardly receives a load against the tension of the strap for portable goods. For this reason, it is only necessary that it be fixed to a degree that can withstand normal use.

However, in practice, when firmly fixed to the covering cover (3) as well, for example, as shown in FIG. 5 as a third embodiment, a projection (33) for preventing the covering cover (3) from dropping off. Or the like, or it can be fixed by various known means such as ultrasonic welding or bonding the covering cover (3) and the thin string.

When the tip of the chain (2a) is hooked on the end of the connecting member (1) as in the first embodiment, the outer diameter of the metal wire of the connecting member (1) may be smaller than that of the chain element. Although it must be smaller than the inner diameter of (20), for example, as shown in FIG. 4 as a second embodiment, the entire hanging string (2) is formed in a loop shape, not at the end of the connection fitting (1). When hooking and crimping on the bent part of the metal wire in the caulking part (11), a connection structure that does not need to consider the outer diameter of the metal wire and the inner diameter of the chain element (20) should be used. it can.

Further, since the connecting fitting in the present embodiment is formed of one metal wire, it can be manufactured at very low cost.

The connecting means of the thin string (4) is not limited to the one in this embodiment. For example, an attaching hole is provided in the string tightening portion (10), and the thin string is passed through the attaching hole to form a loop. Although various known attachment means can be used, it is necessary that the fastening means be capable of securing sufficient connection strength. It should be noted that the fastening means according to the present embodiment can sufficiently secure the connection strength and is excellent in economical efficiency only by the fastening means.

The knot of the loop in the first embodiment is useful for fixing the covering cover as described above, but is not always necessary. Instead, the covering knot and the thin string are directly connected to each other. Can be taken.

Further, according to the present invention, the connection fitting (1) is not limited to the case where the metal wire is formed into a forked shape as in the embodiment, but may be, for example, a hook shape or an S-shaped hook shape. In this case, the chain can be hooked as a loop as shown in Example 2 above.

The metal wire constituting the connecting fitting (1) is made of brass in the embodiment, but may be made of other materials having a bending strength that can withstand the weight of portable goods, such as iron and stainless steel. A wire can be used.
