Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a metal fitting for adjusting the length of a string for personal items such as a strap for a bag or a decorative string for a bracelet.

<Conventional technology> As a length adjustment fitting for a bag strap,
The Japanese-shaped metal fitting 1 having two string insertion holes 2, 2 as shown in FIG. 4 is most widely used. In this metal fitting, a string 3 was passed through two string insertion holes 2, 2, and its tip 4 was looped and fixed to the metal fitting. The length of the string was then adjusted by shifting the thread of the string and changing the length of the double loop.

<Problem that the invention aims to solve> However, there was considerable frictional resistance in shifting the string, making it impossible to shift the string smoothly. Further, this metal fitting is generally used for flat strings, and is not suitable for strings such as metal chains.

<Means for Solving the Problems> Therefore, the present invention has a pair of support pieces 12 and 13 arranged opposite to each other, and at least two string insertion pieces 14 are provided at the tip of one of the support pieces 12. , 15 are erected, and a string insertion piece 18 located between the two string insertion pieces is erected at the tip of the other support piece, and the direction in which both support pieces open relative to each other centering on the proximal end side is erected. A string characterized in that at least one support piece is biased and one end of the string 21 passed through each string insertion piece 14, 15, 18 is fixed at an appropriate position on the metal fitting. The above problems are solved by providing a length adjustment fitting.

<Function> In this metal fitting, at least one support piece is normally biased in a direction in which both support pieces open from each other.
Therefore, as shown in Figure 1B, the two string insertion pieces on one side of the string and the one string insertion piece located between them pull each other in opposite directions, and the string is fixed in that position. It never shifts. By pressing the support piece with a finger or the like and bringing both support pieces close together, each string insertion piece is aligned in a straight line, the force applied to the string is removed, and the string can be smoothly shifted.
(Figure 1A).

<Example> An example of the present invention will be described below based on the drawings.

FIGS. 1A and 1B are side views of the first embodiment, and the string length adjustment fitting 11 of this embodiment has a pair of support pieces 12 and 13 arranged opposite to each other, and both supports. The pieces 12 and 13 are continuous at their proximal ends, forming a generally U-shaped spring body as a whole. Due to this spring action, both support pieces 12 and 13 are biased in a direction in which the distal end side opens (in the direction of arrow b) with the base end side as the center.

Two string insertion pieces 14 and 15 are erected at the tip of one of the support pieces 12, and string insertion holes 16 and 17 are formed in each of the string insertion pieces 14 and 15.

A string insertion piece 18 having a string insertion hole 19 is erected at the tip of the other support piece 13 .

Further, a guide string insertion hole 20 is formed in the continuous portion of the proximal end of both support pieces 12 and 13.

Then, the string 21 (in this embodiment, a string made of braided metal wire) is inserted into each string insertion hole 20, 16, 19.
17 in order, loop one end of it and attach it to the mounting bracket 2.
2 and fixed to an appropriate location on the length adjustment fitting 11. In this embodiment, the fixing point is the string insertion piece 15 of one of the support pieces 12, and a fixing piece 23 having a hole is extended from the end thereof, and is fixed via a ring 24. In the figure, 25 indicates a fixture attached to the tip of the string, and a ring 26 is provided at the tip. Then, this ring 26 and the ring 2
4, the string 21 is fixed to the length adjustment fitting 11.

The mounting fitting 22 has a ring portion 29 at its base end, and is connected to a fixing ring 31 provided at one end of the base of the handbag 30 or the like.

On the other hand, a fixing device 27 having a ring 28 is provided at the other end of the string 21, and a fixing ring 32 at the other end of the base of the handbag is connected to this ring 28.

Next, how to use the length adjustment fitting 11 of this embodiment will be explained. Support pieces 12 and 13 of this metal fitting 11
is normally biased in the direction of arrow b, as shown in FIG. 1B. Therefore, the string 21 is pulled in opposite directions by the two string insertion pieces 14 and 15 of one support piece 12 and the string insertion piece 18 of the other support piece 13 located between them. It is fixed in that position and does not shift, and the length of the string remains unchanged.

Next, to adjust the length of the string, as shown in FIG. 1A, both support pieces 12 and 13 are pressed in the direction of arrow a. Then, the string insertion holes 16, 17, 19 of each string insertion piece 14, 15, 18 are aligned in a straight line, and the string 2
1 can be slid without receiving any resistance. Therefore, the length of the string can be smoothly adjusted by shifting the string and changing the length of the looped portion. In this embodiment, when the tip of the string insertion piece 18 of the other support piece 13 comes into contact with one of the support pieces 12, each string insertion piece 14, 1
The string insertion holes 16, 17, and 19 of 5 and 18 are adjusted so that they are aligned in a straight line. In addition, this position adjustment is
This may be done by using one of the string insertion pieces 14, 15, or by separately providing a stopper.

In addition to the embodiments described above, the present invention can be modified in various ways, and examples of the modifications are listed below.

(a) As shown in FIG. 2, the support pieces 12 and 13 are rotatable via a hinge portion 41 and biased by a separate spring 42.

(b) The spring in Figure 2 is a compression coil spring, etc.
The biasing means can be changed as appropriate.

(c) The number of string insertion pieces 14, 15, and 18 shall be 4 in total, including 18' as shown in Figure 2, and
It may be increased further.

(d) The fixing piece 23 that fixes the end of the string 21 is
As shown in the figure, it may be provided on the other support piece 13 side, and it is not necessarily necessary to provide it at the tip. Furthermore, the ring-shaped fixing piece 23 may be replaced with an appropriate fixing means such as brazing.

(e) The material of the string is free and can be changed to various types such as chain, leather string, cloth string, etc.

(F) This metal fitting can be used not only as a strap for handbags, but also for other bags and bags, and even as a length adjustment fitting for bracelets and chains.

(g) The shape of the string insertion hole 16 of the string insertion piece 14 can be changed in various ways, and as shown in FIG.
may be formed to increase friction with the string and prevent the string from slipping. Further, the string insertion hole of the string insertion piece may be partially cut out, provided that the string does not come off easily.

(H) One of the supporting pieces 12 and 13 may be fixed to the handbag body, and only the other may be rotatable.

<Effects of the invention> As described above, the present invention uses at least two string insertion pieces and a string insertion piece placed between them to pull and fix the strings in opposite directions, so that the strings do not always shift. The length of the string can be reliably maintained at a constant level. When adjusting the length of the string, press both supporting pieces with your fingers in a direction that brings them closer to each other, so that each string insertion piece is aligned in a straight line.
The length can be adjusted by smoothly shifting the string. Therefore, it is possible to provide a simple and reliable string length adjustment fitting.
