Abstract

PURPOSE: To tightly bind an article by simple operation only passing the end of a bundling string through the notch groove of a string passing part to pull the same by forming radial notch grooves to the string passing part formed to one place of a binding main body and forming elastic pawl pieces made freely deformable so as to expand and contract and extending in a radius direction to the gaps between the notch grooves. CONSTITUTION: Upwardly narrowing cone-shaped string passing parts 13 capable of passing a bundling string 12 upwardly are formed to two places of the binding main body 11 of a binding 10. Radial notch grooves 14 are formed to each of the string passing parts 13 to form elastic pawl pieces 15 made freely deformable so as to expand and contract between the notch grooves 14. At a time of use, both ends 12a, 12b of the bundling string 12 are passed through the notch grooves 14 from a slit 16 to be allowed to protrude upwardly and, next, one end 12a of the bundling string 12 is upwardly pulled by one hand while the binding 10 is pushed down toward an article 17 by the other hand. After fastening, when the hand is released from one end 12a on the pulling side, one end 12a is elastically engaged between the elastic pawl pieces 15 and a fastened state is held.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener used to fasten both ends of a binding cord when binding articles such as newspapers and magazines or packaging items with the binding cord.

[0002]

2. Description of the Related Art As a fastener for a binding cord of this type, there is one shown in FIG. 5, for example. This is formed by integrally forming two left and right stop rods 23 on a front frame rod 21 of a rectangular frame body 20 made of plastic via a thin hinge portion 24 so as to be bendable. When using this, as shown in FIG. 6, the left and right stop rods 23 are respectively bent at the thin hinge portions 24 so as to overlap the rear frame rod 25 of the frame body 20, and as shown in FIG. Both ends 12 of the binding cord 12 such as a packing polypropylene tape (PP tape) in which 17 are bundled
The a and 12b are passed between the left and right stop rods 23 in the frame body 20 from below. Then, one end 12a of the binding cord 12 is folded back so as to wrap around the upper side of the left stop rod 23, and is passed downward between the stop rod 23 and the left frame rod 26, and the other end 1
2b is folded back so as to wind up above the right side stop rod 23 and passed downward between the stop rod 23 and the right frame rod 27, so that the left and right stop rods 23 and the left and right frame rods 26, 27 are Both ends 12a and 12b of the binding string 12 can be clamped and fixed.

[0003]

However, in the above-described conventional fastener, the stop rod 23 must be bent and both ends 12a and 12b of the binding cord 12 must be folded back one by one, which is not only troublesome. However, if the fastener is inadvertently lifted upward when carrying after binding, there is a drawback that the end of the binding string 12 easily slips between the frame body 20 and the stop rod 23 and becomes loose. An object of the present invention is to solve such a problem, and it is an object of the present invention to provide a fastener for a binding cord that can facilitate and ensure the binding work of articles.

[0004]

A binding cord fastener according to the present invention has an upper narrowed cone-shaped cord passing portion formed in at least one location of a fastener body, and a radial notch groove is formed in the cord passing portion. However, elastic claw pieces extending in the radial direction and extending and contracting freely are formed between the notch grooves. Here, the cone shape is used to include a cone shape and a pyramid shape. The fastener main body is provided with a cut end that extends from a part of the outer peripheral edge of the fastener main body to the cutout groove.

[0005]

The end of the binding string for binding the articles is passed through the notch groove of the string passing portion and then pulled out from the notch groove while expanding and deforming the elastic claw piece by pulling in the upward narrowing direction of the string passing portion. However, even if it is pulled in the downward spread direction opposite to the upward narrowing direction, it cannot be pulled out from the notch groove because it elastically engages with the elastic claw piece and causes the elastic claw piece to contract and deform. That is, the binding string can be passed through the string passing portion only in one direction, and cannot be passed in the other direction.
The end of the binding cord can be passed through the notch groove from the lower spread side opposite to the upper narrow side of the string passing part, but if a cut is provided, it can also be passed from one side of the fastener main body .

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view showing a use state of a binding cord fastener according to the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a front view showing a part of the fastener broken away. 2 and 3, the fastener 10 is a molded plastic product such as nylon, and the binding string 12 is passed only in one direction (upward) through the two locations on the upper surface of the rectangular plate-shaped fastener body 11. The upper narrowed cone-shaped cord passing portions 13 that can be formed are arranged integrally in a protruding manner. Each threading part 1
3 is formed with a radial notch groove 14, and the notch grooves 14, 14 are formed.
An elastic claw piece 15 extending and contracting and extending in the radial direction is formed therebetween. The tips 15a of the elastic claw pieces 15 are sharpened so as to easily bite into the binding cord 12. The binding cord 12 is provided with a cut end 16 continuous with the cutout groove 14 from a part of the outer peripheral edge of the fastener main body 11 so that the binding cord 12 can be passed through the cutout groove 14 from one side of the tightening body 11. Tie string 1
A round string formed by twisting a plastic film or paper or a flat string such as PP tape is used as 2. However, the central portion 14a of the radial cutout groove 14 is set smaller than the diameter of the binding cords 12.

Next, how to use the fastener will be described with reference to FIG. First, as shown in FIG. 4A, both ends 12a and 12b of the binding cord 12 for bundling articles 17 such as old newspapers and magazines.
Through the cutouts 14 of the two string-passing portions 13 to project upward. Then, while holding the fastener 10 with one hand and pushing it down in the direction A that approaches the article 17, the other hand grasps one end 12a of the binding string 12 and pulls it from the notch groove 14 in the direction B. Then, as shown in FIG. 1B and FIG.
The other end 12b does not move in the direction B from the notch groove 14 in order to elastically lock the elastic claw piece 5 to reduce and deform the elastic claw piece 15, and the one end 12a on the pulling side expands and deforms the elastic claw piece 15. As it is being pulled out, the article 17 is gradually pulled out upward, so that the article 17 is gradually tightened. After tightening, release the end 12a on the pulling side,
Since the one end 12a is elastically locked between the elastic claw pieces 15, it is prevented from returning backward, and there is no fear that the tightened state is loosened. After binding, even if the fastener 10 is lifted when carrying the article 17, the both ends 12 of the binding string 12
The elastic claw piece 15 bites into the a and 12b more strongly, and the binding state does not loosen.

In the above embodiment, the upper narrowed cone-shaped cord passing portions 13 are provided side by side at two positions of the fastener main body 11, but instead, the upper narrowed cone-shaped cord is provided only at one location of the fastener main body 11. Both ends 12a, 12 of the binding cord 12 for bundling the articles 17 in the single cord passing portion 13 by providing the passing portion 13
It can also be bound by passing b in the same direction. Further, although the fastener 10 in the above embodiment is formed of a plastic material, it may be formed of a metal plate material such as stainless steel.

[0009]

As described above, according to the present invention, a radial notch groove is formed in at least one portion of the fastener body, and a radial notch groove is formed between the notch grooves to allow expansion / contraction deformation. Since the elastic claw pieces are formed, the article can be tightened by a simple operation of passing the end of the binding cord through the notch groove of the cord passing portion and pulling it in one direction. After tying, the tying cord can be reliably prevented from loosening, and the tightened state can be firmly held, which is convenient for carrying.
