Description

[Detailed description of the invention] This invention relates to a tightening adjustment device that is attached to the tightening part of a jumper, hat, pants, etc., and its purpose is to
To provide a tightening adjustment tool that does not damage other objects, securely locks a slider, maintains adjustment function over a long period of time, and has excellent durability.

As this type of tightening adjustment device, saw-shaped teeth are carved on both sides of the adjustment belt, and a slider that slides across the belt can be elastically opened and closed in a direction perpendicular to the longitudinal direction of the adjustment belt. There is a known slider that is very popular and has a slider provided with a claw that engages with the teeth.

This adjustment belt is made of synthetic resin, and the tips of the teeth on the side of the adjustment belt may get caught on the outer surface of the belt, causing damage to the object or other objects. However, there was a drawback that the tooth tips were worn and the engagement relationship between the teeth and claws became loose.

This invention was devised to solve such conventional drawbacks, and examples will be specifically described below with reference to the drawings.

In Figure 1, A is an adjustment belt that is sewn to the first garment C, and B is a slider that is secured to the second garment C. Both are molded from synthetic resin and are adjustable. The belt A is a belt-shaped body, and on the back side thereof, a large number of legs 1 are arranged in two rows in the longitudinal direction in an evenly spaced arrangement, and the outer surface of each leg 1 is provided with saw teeth as shown in the third figure. It has zigzag-shaped teeth 2 protruding as shown in FIG. In addition, protrusions 4 are provided at equal intervals on both edges to reinforce the adjustment belt A and to enable it to be bent.

The leg portions 1 may be provided protrudingly over almost the entire length of the adjustment belt A, but this would impair flexibility, so it is preferable to provide them at intervals. In this case, the left and right legs 1, 1 may be arranged parallel to each other and facing each other, and may be arranged in a staggered manner.

The slider B is constructed by integrally connecting two opposing guide walls 5, 5 that slide along both sides of the adjustment belt A with thin elastically deformable connecting parts 6, 6. 6.
-6 is the guide wall 5, at both the front and rear ends of the guide walls 5, 5.
The connecting portion 6 is provided at an intermediate position in the height direction of the connecting portion 6.
, 6 is provided with a guide groove 7 for passing the adjustment belt A therethrough, and a plurality of claws 8 protruding from the inner surface of the lower end of both guide walls 5, 5 to mesh with the teeth 2 of the adjustment belt A. This is what I did.

Note that the distance above the connecting portion 6 between both guide walls 5, 5 is maintained, but when this distance is shortened and the lower end is pushed out from the connecting portion 9, the distance between the opposing claws 8, 8 is adjusted. The opening is smaller than the width of belt A, and escape from adjustment belt A is prevented by restricting openings larger than the width.

Furthermore, depressions 9, 9 are provided on the outer surfaces of both guide walls 5, 5 to prevent slipping.

This device has the above structure, and is assembled by inserting the adjustment belt A into the guide groove 7 of the slider B. When moving the slider B, a clamping force is applied to the upper ends of both guide walls 5, 5. For example, the connecting portion 6.6 is elastically bent, the lower ends of both guide walls 5, 5 are expanded outward, and the pawl 8 escapes from the teeth 2 of the adjustment belt A, so that the slider B can be freely moved. When the slider B is moved to the desired position, if the clamping force applied to both guide walls 5, 5 is removed, the pawl 8 will be pressed against the tooth 2 by the restoring force of the connecting parts 6, 6. It's something that fits together.

As described above, the tightening adjustment device according to this invention has zigzag-shaped teeth protruding from the outer surface of the legs provided in the longitudinal direction on the back surface of the adjustment belt, and both guide walls of the slider inserted through the adjustment belt. They are connected together by an elastically deformable connecting part, and both guide walls have protruding claws that engage with the teeth, so the teeth of the adjustment belt are not exposed on the outer surface and do not get caught on adherends or other objects. Therefore, it does not damage the adherend and protects the tooth tips, so it always maintains a reliable bonding relationship and can withstand a long period of time.

In addition, when the slider slides, both sides of the adjustment belt serve as guide surfaces for the slider, making the slider slide smoothly.Furthermore, since the teeth and pawls are protruded in a zigzag pattern, both sides of the adjustment belt serve as guide surfaces for the slider. When the clamping force is removed from the wall, the teeth and claws mesh accurately and maintain a stable state no matter where the slider is located.
