Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an adjuster for adjusting the lens distance of swimming goggles and a locking tool for a band for swimming goggles. More specifically, the present invention relates to an adjuster for connecting two eyeglass parts of swimming goggles and a swimming goggle band locking tool for securing the swimming goggle band to the goggles.

[Prior Art] Swimming goggles are used to protect the eyes from residual chlorine in pools while swimming.
In order to secure the swimming goggles around the eyes, a stretchable rubber band is wrapped around the head (Figure 8). The adjustment adjuster 106 that connects the two glasses is made of soft plastic and has a band-like shape, and length adjustment projections 107 are provided at fixed pitches on both ends of the adjustment adjuster 106. Furthermore, various structures have been proposed for fixing swimming goggles and rubber bands.

For example, the method shown in FIG. 8 involves inserting a rubber band 104 into a locking part 102 formed in a glasses body 101 made of transparent plastic, bending it back, and overlapping it to form two Japanese-shaped bands. Stops 105 stop both ends of the rubber band 104.

[Problem to be solved by the invention] The eyeglass body 101 made of soft plastic described above
The adjustment adjuster 106 in between can only be adjusted by about 5 mm because the number of adjustment protrusions 107 attached to both ends thereof is limited. There is a drawback that if the rubber band 104 is tightly tightened during installation, the adjuster 106 will stretch, and furthermore, adjusting the adjuster 106 requires strong force for the protrusion 107 to get over the insertion hole, which is difficult for children with weak strength to do. There is.

Furthermore, to fix the swimming goggles and the rubber band 105 described above, two band stops 105 are required as shown in FIG. 8, and adjustment of the length also needs to be done at two places. In addition, the band stopper 105
Because it is necessary to pass the rubber band 104 through and fix it, it takes time and effort to pass the rubber band 104 through it.
Further, this invention is characterized in that it solves these problems and at the same time makes the adjuster portion simple and beautiful in appearance.

The purpose of this invention is to provide an adjuster that can freely adjust the distance between the glasses bodies of swimming goggles.

Another object of this invention is to provide a fastener for a swimming goggle band that is easy to put on and does not come off easily.

A third aspect of the present invention is an adjuster for adjusting the distance between lenses of swimming goggles having two eyeglass bodies, including a connecting means provided on each of the two eyeglass bodies, and a plurality of adjusters having different lengths connected to the connecting means. This is an adjuster for adjusting the lens spacing of swimming goggles, which is composed of a stabilizer plate.

A fourth aspect of the present invention is a band fastener for swimming goggles having two eyeglass bodies, including a hole provided in the eyeglass body through which the strap is bent back and passed through, and a hole inserted into the hole through which the band is passed. This is a fastening device for a band of swimming goggles, which fixes the strap to the buckle body by providing a buckle body having a hole for the strap and a protrusion on the hole portion or the buckle body.

[Function] The adjuster blocks are connected to the connecting means provided on the eyeglass bodies of the swimming goggles, and the distance between the two eyeglass bodies is adjusted to the optimum length by converting plates with different numbers or lengths of adjuster blocks. Adjust. Another method is to provide a plurality of insertion holes in the adjuster body, and insert the protrusions of the eyeglass body into the holes to adjust the length. The strap is passed through a hole provided in the eyeglass body, then passed through a hole in a T-shaped fastener, bent back, and then inserted back into the hole in the eyeglass body. Thereafter, a locking tool is inserted into the hole in the eyeglass body to fix the strap.
