Abstract

<P>PROBLEM TO BE SOLVED: To provide a strap-adjusting tool preventing shoulder straps of a brassiere from easily slipping, the length of the straps from unintentionally changing and the straps from easily slip and deviating when washing to one side. <P>SOLUTION: This strap-adjusting tool has seizing catches in the inside of the central part in the longitudinal direction of a front frame and a back frame each making a round shape unitedly with a central rod and forming strap through-holes in the inside. The seizing catches each project toward the center of the string through-hole. The unintentional change of the length caused by slipperiness of the string is prevented by securely seizing by pressure the strings with the seizing catches. Front and back edges viewed from the front of the central rod are each formed in a dent arc type or a wide angle V-shaped type making a gentle down grade from both the ends towards the central part so as to prevent the string from slipping and inclining to one side each of the right and the left of the strap-adjusting tool. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord adjuster for adjusting and stopping the length of shoulder straps mainly used for clothing materials such as brassieres and swimwear.

[0002]

2. Description of the Related Art A conventional string adjuster of this kind is generally called an eight ring, and is a figure-eight figure in which a gate-shaped or oval front frame and a rear frame are united in front of and behind a central rod that forms a horizontally long straight line. It is molded into a shape.

It is also known to provide a serrated blade-shaped engaging claw in the lateral direction on the inside of a front frame or a rear frame having a gate shape.

[0004]

The problem to be solved is that in a tape-shaped shoulder strap such as a brassiere, the strap fixed by the strap adjustment tool is slippery and the length of the shoulder strap changes randomly. In addition, the shoulder straps tend to shift to the left and right sides of the cord adjuster due to washing and the like, and are easily biased.

In the case of a saw-toothed locking claw (it is necessary to make the tip of the claw round so as not to damage human skin), one claw is extremely small, and the overall size is about 15 to 18 mm. The adjuster has a weak locking force and cannot effectively prevent the string from slipping.

Further, in the conventional cord adjuster, since the cord passing hole formed by the central rod, the front frame and the rear frame is formed in a narrow and long gap through which the cord is almost passed,
There is a problem in that the front and rear widths of both side surfaces of the string adjuster are small, and when adjusting the length of the string, the string adjusters are moved by pinching both narrow side surfaces with fingers, which is a problem.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a front frame and a rear frame, each of which has a ring shape integrally formed with a central rod and has a string passage hole formed therein, are provided respectively inside the central portions in the longitudinal direction of the front frame and the rear frame. By providing a locking claw that protrudes toward the center of the string through hole, and by securely pressing and locking the string with this locking claw, it is most important to prevent random changes in length due to sliding of the string. In addition, by forming the front and rear edges seen from the front of the central rod in a concave arc shape or a wide-angle V-shape with a gentle downward slope from both ends toward the central part, the cord can be used as a cord adjustment tool. It is characterized in that it is slipped to one side on the left and right sides to prevent the deviation.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Inside the central portions in the longitudinal direction of the front frame and the rear frame, which form a ring shape integrally with the central rod and form the string passing holes inside thereof, respectively, at the centers of the string passing holes. Providing locking claws projecting toward the front, the front and rear edges seen from the front of the central rod are formed in a concave arc shape or a wide-angle V shape with a gentle downward slope from both ends toward the central portion.

[0009]

[Embodiment] The cord adjuster 1 shown in FIG. 1 is one in which a tape-shaped cord is passed through and the length is adjusted to be locked (single type). From the front to the front and rear frames extending symmetrically in the front-rear direction into an arch shape (including an arc shape and a gate shape with rounded corners), forming a ring shape integrally with the central rod 2 and forming a string passage hole 3 inside thereof. 4 and the rear frame 5 are formed into a substantially 8-shaped plane.

The central rod 2 has front and rear end edges 2 as seen from a plane.
Each of a and 2b is formed in a concave arc shape or a wide-angle V shape that has a gentle downward slope from both ends toward the central portion.

Locking claws 6 projecting toward the center of the string passing hole 3 are provided inside the central portions in the longitudinal direction of the front frame 4 and the rear frame 5, respectively.
Is formed in a mountain shape having one or a plurality of tops.

The cord adjuster 1 shown in FIG. 2 is one in which two tape-shaped cords are passed through and the lengths thereof are adjusted and locked (double type). The single type shown in FIG. It is formed in a shape in which two pieces are united.

That is, the left and right central rods 2, 2 integrated in series extend symmetrically in the front-rear direction in an arch shape, and form a ring shape integrally with the central rod 2. The front frames 4 and 4 and the rear frames 5 and 5 respectively forming the above are formed into a four-leaf clover shape in a plan view.

Similar to the single type shown in FIG. 1, the central rod 2 is a concave arc type or a wide-angle V type in which the front and rear edges 2a and 2b as viewed from the front form a gentle downward slope from both ends toward the central portion. Locking pawls 6 formed in a mold and projecting toward the center of the string passing hole 3 are provided inside the central portions in the longitudinal direction of the front frame 4 and the rear frame 5, respectively. The tip of 6 is formed in a mountain shape having one or a plurality of tops.

In the double type cord adjuster 1 shown in FIG. 5, a plurality of threading holes 7 are formed at the intersections of the central rods 2, 2 and the front frame 4 and the rear frame 5 at the center thereof.
A needle and a thread are passed through the threading hole 7 so as to attach a button for clothes, and a decoration 8 such as a ribbon or an artificial flower can be sewn on the string adjusting tool 1 as shown in FIG.

As the material used for the string adjusting tool 1, various synthetic resins, various metals such as stainless steel and brass can be used for molding, and when metal is used, the surface thereof is plated, painted or nylon coated. Surface treatment such as.

FIG. 7 shows a usage mode of the cord adjuster 1, in which one end of the shoulder strap 9 is passed from the back side of the cord adjuster 1 through the cord passing hole 3 on the front side and further while being wound around the central rod 2. The string adjusting hole 1 is passed through the string passing hole 3 on the side, and is brought out to the back side of the string adjusting tool 1, and the exposed end is bound to the shoulder string 9 with a thread or the like.

As shown in FIG. 6, the other end of the shoulder strap 9 is passed through a suspension ring 11 attached to the top of the chest plate of the brassiere 10 and then passed through a strap passage hole 3 on the rear side of the strap adjuster 1. Further, while overlapping the other end of the shoulder strap 9 wound around the central rod 2 and bound, it is passed through the front string passing hole 3 and put out to the back side of the strap adjusting tool 1, and this is tightened on the back side of the brassiere 10. To meet.

When the length of the shoulder strap 9 is adjusted in this state, the shoulder strap 9 which is overlaid on the other end of the shoulder strap 9 is loosened and pulled out onto the strap adjuster 1, and this is adjusted. Before and after (string adjuster 1
If it is in the vertical orientation, pull it up or down to adjust the overall length of the shoulder strap 9.

At this time, the locking claws 6 at the central portions of the front frame 4 and the rear frame 5 hold the shoulder straps 9 from above and lock them so as not to move easily (especially, the locking claws 6 are relatively It can be formed large, and the center of the shoulder strap 9 in the width direction can be concentrated and reliably locked.

On the other hand, the other end portion of the shoulder strap 9 wound around the central rod 2 and bound thereto and the shoulder strap 9 laid on the shoulder strap 9 and wound around the central rod 2 extend from both ends of the central rod 2 to the central portion. The front and rear end edges 2a, 2b formed in a concave arc shape or a wide-angle V-shape forming a gentle downward slope are acted so that the left and right side portions are always slid toward the central portion of the central rod 2. Therefore, it is difficult to bias the cord adjuster 1 to the left or right side,
It is possible to prevent the shoulder straps 9 from shifting to one side of the strap adjusting tool 1 and being biased due to washing or the like.

Further, in this state, the locking claw 6 presses and locks the center portion of the shoulder strap 9 in the width direction, so that the shoulder strap 9 is further edged in the concave arc shape or wide-angle V-shape of the central rod 2. Since it is pushed into the central portion side of 2a, 2b, the bias of the shoulder strap 9 can be prevented more reliably in combination with the central pulling action of the concave arc-shaped or wide-angle V-shaped end edges 2a, 2b.

Further, since it is necessary to form a space for passing the tape-shaped shoulder strap 9 between the center rod 2 and the tips of the locking claws 6, the left and right portions of the locking claws 6 of the front frame 4 and the rear frame 5 are formed. As a result of the distance between the center rod 2 being increased and the front and rear widths of the side faces of the cord adjuster 1 being correspondingly increased, when the length of the shoulder strap 9 is adjusted, the side faces having the large width are pinched with fingers. Since the adjustment tool can be moved, the adjustment operation becomes easy, and the curvature of the two arcs on both sides of the string adjustment tool 1 can be formed to be large. The contact pressure can be dispersed, and a string adjuster that is easy on the skin can be obtained.

[0024]

As described above, according to the present invention, the locking claws at the central portions of the front frame and the rear frame lock the shoulder straps from above so that they cannot be easily moved, and particularly, the locking claws. Can be formed to be relatively large, and the shoulder strap can be reliably locked in the center in the width direction.

The other end of the shoulder strap wound around and bound to the central rod and the shoulder strap wrapped over this and wrapped around the central rod have a gentle downward slope from both ends of the central rod toward the central portion. The front and rear edges formed in a concave arc shape or a wide-angle V-shape have the effect that the left and right side parts are always slid toward the center part of the central rod. Therefore, it is possible to reliably prevent the shoulder straps from slipping into one side of the string adjusting tool 1 and being biased due to washing or the like.

Further, since the locking claw presses and locks the center portion of the shoulder strap in the width direction, the shoulder strap is pushed further toward the center portion side of the concave arc-shaped or wide-angle V-shaped edge of the center rod. become,
The bias of the shoulder straps can be more reliably prevented in combination with the central pulling action of the edge of the concave arc type or the wide-angle V-type.

Furthermore, since the front and rear widths of both side surfaces of the string adjuster can be formed to be large, when the length of the string is adjusted by pinching this part with a finger, the adjusting operation can be easily performed, and both side parts of the string adjuster can be adjusted. Even when it contacts with, the contact pressure can be dispersed to soften the contact.
