Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a belt fixing device for goggles, diving masks, etc.

(Prior art) Conventional goggles use a buckle as a means for fixing the belt, and the belt led out from the buckle is passed through a hole in the goggle body, folded back, and the end is further passed through the buckle and fixed while adjusting the length. It is something.

(Technical issue) Although this structure allows the belt to stop firmly,
The work of adjusting the length of the belt is troublesome and is especially inconvenient for children to handle.

Recently, it has been considered to pass the belt through two parallel holes in the goggle body without using a buckle, and to fix the belt simply by the frictional force generated between the holes, but this method also does not work. Difficult to adjust,
The disadvantages are that the belt may shift due to strong pulling force, and it is too stiff and difficult to move.

SUMMARY OF THE INVENTION An object of the present invention is to provide a belt fixing device for goggles, which eliminates the above-mentioned drawbacks of the prior art and allows the belt to be adjusted quickly and easily.

(Technical Means) The purpose is to form a flat vertical hole 3 in the outer end of the main body 1 of the goggles, into which the polymerized rubber belt 2 is inserted.
, a straight rod portion 4a, a frame portion 4b' arranged substantially parallel to the rod portion 4a, and a rod portion 4a and the frame portion 4.
upper and lower end portions 4c and 4d in which the tips of the portions connected to the upper and lower portions of the rod portion 4a protrude to the sides of the rod portion 4a, and the rod portion 4
a. A stopper 4 consisting of an insertion window hole 4b surrounded by a rod portion 4b' is arranged on the front side of the main body, and a folded portion of the rubber belt 2 passed through the flat vertical hole 3 from the back side of the main body is hung around the rod portion 4a, This can be achieved by a structure in which the stopper 4 is crimped onto the main body 1 by pulling the folded end back from the flat vertical hole 3 to the back side of the main body.

The stopper 4 is formed by hanging the rubber belt 2 on one of two rods formed approximately in parallel.
The other rod has an end 4 that protrudes from the one rod side.
c and 4b are used as fulcrums to operate when pulling up the stopper.

The stopper 4 may have a shape in which one loop of a figure 8 is cut out in half, and basically consists of an intermediate rod portion 4a, a frame portion 4b', and protruding parallel ends 4c, 4.
It is sufficient if it has d.

(Example) To explain with reference to the drawings, the example is 2.
In the eye goggles, a flat vertical hole 3 through which a superimposed rubber belt 2 can be inserted is formed at the outermost end of a pair of upper and lower main bodies 1. A stopper 4 for stopping the rubber belt 2 is connected to a straight rod portion 4a and a frame portion 4b' that continuously forms insertion holes 4b near both ends of the rod portion 4a at the top and bottom of the rod portion 4a. It consists of an upper end part 4c and a lower end part 4b whose tip end protrudes to the side of the rod part 4a.
b' continues near both ends of the intermediate rod portion 4a, and end portions 4c and 4d protrude outward from this portion, forming an approximately D-shape or flattened A-shape as a whole.

These upper and lower ends 4c and 4d contribute to making the crimped stopper 4 in contact with the main body surface and make it more stable, and since they protrude, they serve as fulcrums when pulling up the stopper. Since 4d serves as a fulcrum, the rubber band 2 becomes easier to pull out as the rod portion 4a separates from the surface of the main body during lifting.

The rubber belt 2 pulled out from the back side of the main body is folded back into a U-shape and hung on the rod portion 4a. The rubber belt 2 is pulled back from the front side of the main body 1 to the back side again with the folded end overlapped with the flat vertical hole 3, and when pulled strongly, the stopper 4 is pressed against the main body 1 and can be stopped. In the figure, 5 is a joint part, 6 is a band stopper, and 7 is a sponge buffer part. The flat vertical hole 3 is located at the edge of the buffer section 7 (FIG. 3), and the rubber band 2 comes into contact with it and receives friction to prevent it from slipping.

(Operation of the device) In the above structure, when the frame portion 4b' of the stopper 4 is used as a point of effort and the upper and lower ends 4c and 4d are pulled up as fulcrums, the belt 2 immediately loosens due to the levering force, and then the belt 2 is moved to expand and contract. The length can be adjusted freely.
The tension of the belt 2 presses the stopper 4 onto the surface of the main body and firmly fixes it, so there is no risk of loosening during use.

In particular, in the fixing device of the present invention, the stopper 4 is formed in a substantially D-shape, and the rubber belt 2 is wrapped around the straight rod portion 4a to fix it, so that the frame portion 4b' can be hooked with a nail and pulled up. It is easy to pull up the rod part 4a.
The more protruding ends 4c and 4d act as fulcrums and the rubber belt 2 is moved significantly, so that it loosens from the state in which it is in close contact with the stopper 4, making it easier to pick it out with your fingertips.

(Effects of the invention) Therefore, according to the invention, the rubber belt 2 can be stably attached by the stopper 4 that is crimped onto the main body 1, and the stopper 4 can be easily pulled up using the protruding ends 4c and 4d as fulcrums. Since the length can be adjusted by loosening the rubber belt 2, the belt can be adjusted quickly.
The intended purpose of simplification has been achieved, and since it is structurally simple, it is easy to implement, and has significant practical effects.
