Abstract

PROBLEM TO BE SOLVED: To prevent lace from slipping off by processing a channel in the push member so that it forms a gap to hold the lace in opposite direction to the pushing force of the spring in the lace hole. SOLUTION: On a push-in 7 of a push member 2 is processed a channel 13 adjacent to the part opposite to the pushing force of a spring 3 so as to form a gap of appropriate width. When using, you push the push member 2 into a body 1 with the finger against the pushing force of the spring 3 as far as it stops and aligns a first eyelet 10 and a second eyelet 11 when a rim 12 of a head 8 touched the top of the body 1. Put now a lace 4 through the eyelets 10, 11, 10 and take off the finger. Then being pushed up by the spring, the lace 4 falls into the gap formed by the channel 13 and caught held there between inside of the body 1 and outer surface of the push-in 7. As the friction there comes much higher and the eyelets 10, 11, 10 bite the lace 4 much harder, it's kept there tight without slipping off not requiring to use another stronger spring 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord stopper, and more particularly to a cord stopper for stopping an end portion of a cord used for clothes.

[0002]

2. Description of the Related Art Clothes, for example, a tie for attaching to the hem of a jacket, a neck, a hem of a hood, etc., or a cord stopper for stopping the end of a decorative cord attached to an arbitrary place of the garment is known. Is. FIG. 3 shows the structure of a typical cord stopper, which is usually manufactured by injection molding of a hard plastic such as polypropylene or polyacetal. A push member 2 is slidably fitted into an inner hole of a circular or square cylinder-shaped main body 1, and one or two cord holes 10 and 11 penetrating these members at right angles to the sliding direction. And the push member 2 is always biased in one direction by the compression spring 3. The push member 2 is pressed against the spring 3 with a finger to align the cord hole 11 with the cord hole 10 of the main body 1, then the cord is passed through the aligned cord hole, and the finger is released. Since the push member 2 is pushed back by the spring 3, the aligned string holes are displaced, so that the string is the string hole 1 of the push member 2 as shown in FIG.
It is sandwiched between the inner surface of 1 and the inner surface of the cord hole of the main body 1 and frictionally locked.

[0003]

In such a conventional cord stopper, the force for stopping the cord is determined by the force of the spring and the frictional force on the inner surface of the cord hole. Since the contact area is small, the cord slips relatively easily when the cord or cord is pulled, and the tightening force has to be increased by increasing the strength of the spring. Therefore, an object of the present invention is to provide a cord stopper that prevents the cord from slipping.

[0004]

According to the present invention, there is provided a main body having an inner hole and at least one first cord hole which is orthogonal to an axis of the inner hole, and a sliding portion which fits into the inner hole of the main body. A push member having at least one second cord hole which is orthogonal to the axis line and which can be aligned with the first cord hole, and the push member in the inner hole is constantly displaced in a direction in which both cord holes are misaligned. In a cord stopper made of a spring to be kept, a gap is formed in the push member at a portion adjacent to the second cord hole on the opposite side to the direction in which the spring is displaced so that the cord is caught and locked. It is characterized in that a groove portion is formed. Alternatively, on the inner wall of the inner hole of the main body, a groove portion is formed in a portion adjacent to the first cord hole on the side of the displacement direction of the spring so as to form a gap enough to sandwich and lock the cord. It is characterized by According to the present invention, the cord can thus be clamped in the gap formed between the push member and the main body, and thereby the clamping force of the cord can be increased.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to Examples of the present invention.

【Example】

Embodiment 1 FIG. 1 is a sectional view of a cord stopper according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view thereof. A string stopper formed by injection molding of hard plastic is a push having a cylindrical main body 1 having an inner hole 6 having an open upper portion, a sliding portion 7 fitted in the inner hole 6, and an enlarged head 8. It comprises a member 2 and a compression spring 3 housed between a recess 9 formed in the bottom of the push member 2 and the bottom of the inner hole 6. In the figure, the main body 1 and the push member 2 have a substantially rectangular horizontal cross section,
It may have another shape such as a circle. On the opposing side walls of the main body 1, one first cord hole 1 orthogonal to the axis of the inner hole 6 is formed.
0 and 10 are formed in line in the horizontal direction. The push member 2 is formed with a second cord hole 11 aligned with the first cord hole 10 when the push member 2 is pushed against the force of the spring 3. The peripheral flange 12 of the enlarged head portion 8 of the push member 2 serves as a stopper, and when the push member is pushed into the inner hole 6 of the main body, it abuts against the top portion of the main body 1 so that the first cord holes 10 and 10 are opened. The second string hole 11 is aligned.
Although not shown, the push member 2 and the spring 3 are connected to the main body 1
In order to prevent the push member from coming off from the main body 1 after being assembled into, the detent composed of, for example, a hook and a locking portion is preferably provided between the outer surface of the sliding portion 7 and the inner hole 6. In the illustrated example, one string hole is used, but a pair of string holes may be formed side by side.

A string hole 11 is formed in the sliding portion 7 of the push member 2.
A groove 13 that forms a gap having a thickness t is formed adjacent to the side opposite to the moving direction of the push member 2 (the direction in which the spring 3 is displaced). Here, the thickness t is set to be sufficiently smaller than the diameter of the cord, but large enough to sandwich the cord. On the other hand, in the conventional example of FIG. 3, the thickness t of the gap is
_{Since 0} is very small, the string cannot enter between the sliding portion of the push member and the wall surface of the inner hole of the main body.

With the above construction, first, the push member 2 is pushed by the finger to push it into the main body 1 against the force of the spring 3. When the peripheral flange 12 of the enlarged head 8 comes into contact with the top of the main body 1, the push member 2 stops and the first cord holes 10 and 10 and the second cord hole 11 are aligned. When the string 4 is inserted into the grooves 10, 11 and 10, and then the finger is released, the string 4 enters the groove 13 forming the gap t, as shown in FIG. Since the string is clamped in the gap between the two, the friction with the string 4 increases, and the edge of the string holes 10, 11, 10 also bites into the string, so that the spring 3 that is not very strong is used. Also, the locking force of the string can be increased, and the locked string can be prevented from slipping.

Embodiment 2 FIGS. 4 to 5 show another embodiment of the present invention. In these drawings, the same members as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, the push member 2
Grooves 13, 13 are not formed in the groove. Instead of body 1
Cutouts or grooves 14, 14 are formed in a portion of the inner hole 6 adjacent to the spring 3 in the displacement direction. The grooves 14 and 14 have a thickness t such that the cord 4 is sandwiched between the outer surface of the sliding portion 7 of the push member 2 and the bottom wall of the grooves 14 and 14 to generate sufficient frictional force. Specified in. It is clear that this example also has the same effect as that of the first embodiment.

[0010]

As described above, according to the present invention, the groove 1
By providing the grooves 3, 13 or the grooves 14, 14, the locking force of the cord can be significantly increased, and the advantage that a spring having a strong elasticity is not required is obtained.
