Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord length adjusting device, and more particularly to a device suitable for adjusting the length of a synthetic resin round cord having a circular cross section.

[0002]

2. Description of the Related Art For example, in the case of a shoulder type carrying various bags, bags, mobile phones, etc., shoulder straps are required.
Synthetic resin and cloth are used as materials. By the way, it is necessary to set the length of the shoulder strap for lowering the width of various members over the shoulder according to the height of the user, and therefore, the shoulder strap is provided with a length adjusting device. Conventionally, the shoulder strap is formed in a strip shape regardless of the material, and various length adjusting devices have been proposed that correspond to the shape of the strap shoulder strap.

[0003]

However, the belt-shaped shoulder strap has a large amount of material to be used in correspondence with the width, and the material cost is high, and the shoulder-type bag or bag which is inexpensive,
When manufacturing a holder for a mobile phone, the shoulder straps occupy a large proportion of the material cost, making it difficult to reduce the price of the product. Considering the above points, if a round cord made of a synthetic resin extruded wire is used as the material for the shoulder strap, the material cost can be reduced and the product price can be reduced. However, since the synthetic resin round cord is slippery, it is useless if the structure of the conventional length adjusting device for a band-shaped cord is adopted as it is, so that it is necessary to develop a new adjusting device that can handle the round cord. Therefore, an object of the present invention is to easily and surely adjust the length of the round cord,
An object of the present invention is to provide a device for adjusting the length of a round string that enables the use of the round string in a shoulder bag, a bag, a holder of a mobile phone, or the like.

[0004]

In order to solve the above problems, the invention of claim 1 has two string insertion holes formed in a peripheral wall of a tubular adjustment tool in a circumferential direction of the peripheral wall. A structure is employed in which one end side of a round cord is connected at a position apart from both cord insertion holes by a peripheral wall of the adjusting tool and provided at intervals.
According to the invention of claim 2, the round string is a round string made of synthetic resin having a circular cross section, the string insertion hole provided in the peripheral wall of the adjusting tool penetrates the peripheral wall in the radial direction, and the round string is in the longitudinal direction. The configuration is such that the inner diameter is adapted so that it can be moved to. According to the invention of claim 3, a spherically-shaped adjusting tool is provided with a string insertion hole which is open at the outer surface of the adjusting tool at both ends with a predetermined interval so as to bend inside the adjusting tool. The configuration is such that one end side of the round cord is connected to a position apart from the opening of the cord insertion hole on the outer surface. Here, if you insert the middle of the round string whose one end side is connected to the adjustment tool through the string insertion hole,
The round string has a loop-shaped part that is inserted from one end side into the string insertion hole, and if the loop part and the other end side of the round string are fixed to the suspended object, the round string becomes a shoulder string. The portion of the round cord that is inserted into the cord insertion hole is bent along the shape of the insertion hole, and if the suspended object is hung with the circular cord on the shoulder, the weight of the suspended object causes the circular cord to hang. The upper and lower parts pulled out from the string insertion hole try to be a straight line up and down, but the weight of the suspended object acts on the adjusting tool by one end side of the round string connected to the outer periphery, and as a result, By raising the position of the string insertion hole,
The bending angle of the portion located in the insertion hole of the round cord and the portion pulled out downward becomes tight, and the middle of the round cord and the adjusting tool are firmly fixed against the pulling force and do not loosen. To adjust the length of the shoulder strap, slide the adjuster in the length direction of the round cord to change the size of the loop. Hold the adjuster with one hand, hold the position close to the adjuster of the cord with the other hand, and pull the cord in the direction of extension of the cord insertion hole. Since the bent portion does not bend, it slides inside the string insertion hole, and the length can be adjusted without any problems.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the first example shown in FIGS. 1 to 3, the adjuster 1 is formed into a cylindrical shape using a synthetic resin, various metals, hard or semi-rigid materials such as wood and ceramics, and the cord 2 is an extrusion of synthetic resin. It is made of wire and is transparent and colored, has flexibility, and has excellent tensile strength. In addition, it is made of leather, synthetic leather, synthetic resin sheet, woven fabric, etc. It may be. As shown in FIG. 1 (B), the peripheral wall of the adjusting tool 1 is provided with a pair of string insertion holes 3 and 4 at a position on one side with a vertical center line A passing through the horizontal axis as a boundary. One end side of the round cord 2 is connected to the position on the other side.

The pair of cord insertion holes 3 and 4 have an inner diameter enough to tightly fit the round cord 2 so that the circular cord 2 can slide in the length direction, and penetrate the peripheral wall of the adjusting tool 1 in the radial direction. In addition, they are arranged side by side at a predetermined interval along the circumferential direction of the peripheral wall. It should be noted that the intervals between the cord insertion holes 3 and 4 in the circumferential direction of the circumferential wall are set so that the cords 2 inserted through the cord insertion holes 3 and 4 approach each other within a range that does not extremely bend in the adjuster 1. Set according to the diameter and flexibility. The connecting position on the one end side of the round cord 2 on the peripheral wall of the adjuster 1 is set to be substantially symmetrical with the lower cord insertion hole 3 across the vertical center line A. In the case shown in the figure, the method of connecting one end side of the round cord 2 to the peripheral wall is to insert one end side of the circular cord 2 into the through hole 5 provided in the peripheral wall from the outside, and to end the end of the circular cord 2 located in the adjuster 1. Although the ball head 6 is provided on the portion to prevent the cord from being pulled out, other connecting methods include providing a knot, welding or adhering to the peripheral wall, and a hook for connecting the end of the round cord 2 to the outer surface of the peripheral wall. A method of projecting a U-shaped connecting tool may be adopted.
The adjuster 1 may be formed in a polygonal tubular body other than the cylinder as shown. The first example has the above-described configuration, and the middle of the round cord 2 whose one end side is connected to the adjuster 1 as shown in FIG. 1 is inserted into the cord insertion holes 3 and 4 from the one end side of the round cord 2. A loop portion 2a is formed between the portions inserted through the adjusting tool 1,
As shown in FIG. 3, the circular cord 2 is used as a shoulder cord by connecting the loop portion 2a and the other end side to the upper two places of the suspended object 7 such as a bag, a bag, and a mobile phone.

FIG. 2 shows a state in which the object 7 to be suspended is hung by a shoulder strap. The upper and lower portions of the cord insertion holes 3 and 4 of the round cord 2 tend to be linear. At this time,
Due to the weight of the suspended object 7, the adjuster 1 is pulled down at a portion where one end side of the round cord 2 is connected, and as a result, the cord insertion holes 3 and 4 are moved to a slightly upper position and the lower cord of the circular cord 2 is moved. The bending angle of the portion pulled out downward from the insertion hole 3 becomes tight, and the adjusting tool 1 is firmly fixed to the round cord 2 without sliding down. When adjusting the length of the shoulder straps, the round cord 2 is placed in a natural state in which no tensile force is applied, the adjusting tool 1 is held by one hand, and the other hand is close to the adjusting tool 1 of the round strap 2. Holding the position and pulling the round cord 2 in the extension direction of the cord insertion holes 3 or 4, the circular cord 2 slides through both cord insertion holes 3 and 4, whereby the loop portion is formed. The length of 2a is changed, and the entire length of the shoulder strap can be adjusted.

Next, a second example shown in FIG. 4 is a synthetic resin,
The adjusting tool 1 made of metal, wood or the like is formed into a spherical shape, and the conditions for connecting the string insertion holes 3 and 4 provided in the adjusting tool 1 and the adjusting tool 1 on one end side of the round string 2 are: This is the same as the first embodiment described above, and in the second embodiment, the string insertion holes 3 and 4 are one passage that is bent in an arc shape and communicates with each other inside the adjuster 1. The fixing action of the adjusting tool 1 and the length adjusting operation with respect to the string 2 can be performed in the same manner as in the first embodiment. The adjuster 1 may be formed in a polyhedron other than the spherical shape.

As described above, according to the present invention, the length of the round cord can be adjusted by the movement of the adjusting tool along the round cord, and when a load is applied, the bending angle of the round cord due to the cord insertion hole is reduced. It can be changed and the adjustment tool can be fixed to the round string, which allows the length of the round string to be easily slipped, and the round string can be used as a shoulder strap for hanging bags, bags, mobile phones, etc. It is possible to reduce the cost of various products by using the round cord as the hanging shoulder cord.
Further, since the adjusting tool may be formed into a tubular shape or a spherical shape and the string insertion hole may be provided in the adjusting tool, the structure is simple and the manufacturing cost is low.
