Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the length of a wearing belt used when wearing underwater glasses, ski glasses, dust-proof glasses, helmets, waist bags and the like on the head.

[0002]

2. Description of the Related Art Conventionally, an operation for adjusting the length of a belt to optimize its tension has been performed as a means for binding or locking such glasses or the like. After passing one end of the belt through a flat-shaped locking device, it is bent at a sharp angle and locked using the frictional force, or a method of inserting a stop pin into a stop hole drilled in the belt, Various adjusting and fixing means such as locking a projection formed on the surface of the belt with a lever-shaped stopper are employed.

[0003]

However, there is a problem to be solved in that all of the above-mentioned locking means are inferior in operability and cannot be adjusted and fixed in length quickly. Particularly in the case of a belt made of an elastic material, The use of the above-mentioned stop holes and the use of the lever-shaped stopper may damage the belt itself.

The present invention has been made in view of the above circumstances, and simply and reliably slides an operating outer cylinder slidably covered by a belt passing main body, thereby easily and reliably increasing the length. It is an object of the present invention to provide a device for adjusting and fixing the length of a wearing belt which can be adjusted and fixed.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and to achieve the object, the present invention provides a flat cylindrical body having a belt passage through which an end of a belt for wearing underwater glasses or the like reciprocates. A belt passing main body integrally formed with a cantilever-shaped pressing elastic body whose outer surface bulges in the belt passing direction and whose free end is bent and protrudes into the belt passage by the pressing of the bulging portion; An operation outer cylinder that is covered by the main body of the belt and presses the pressing elastic body by sliding movement in the belt passing direction, and one end of the belt passed through the main body of the belt is formed on underwater glasses or the like. It is folded back by a through ring or the like and passed again through the belt passing main body, and the belt in the superimposed state in the belt passing main body is pressed and fixed by the free end of the pressing elastic body which is bent by the sliding movement of the operation outer cylinder. Mounting characterized by the fact that It is obtained by the length of the belt adjusting locking device.

[0006]

As described above, the pressing elastic body protruding from the plane of the belt passing main body made of a flat cylindrical body having a belt passage through which the end of the belt is folded and formed to reciprocate is covered by the belt passing main body. When the operation outer cylinder is slid and pressed,
The free end of the pressing elastic body protrudes into the belt passage and presses the belt surface in the overlapped state to be fixed.When the operating outer cylinder is slid in the opposite direction, the pressing by the pressing elastic body is released. Since the length of the belt can be freely adjusted, the length can be easily adjusted and fixed only by the sliding operation of the operation outer cylinder.

FIG. 1 is an exploded perspective view of a mounting belt length adjusting device according to the present invention, and FIG. 2 is a cross-sectional view of a fixing state of the belt. And an operation outer cylinder 2.

The belt passing main body 1 includes a wearing belt B
The outer surface gradually bulges in one of the flat surfaces of the flat cylindrical body 4 having the belt passage 3 through which the end of the belt passage 3 passes.
A cantilever-shaped pressing elastic body 6 protruding by bending inward is integrally formed, and a retaining projection 7 is provided on a base end side edge of the pressing elastic body 6.
Are formed.

The operating outer cylinder 2 has a width corresponding to the width of the pressing elastic body 6 at a position corresponding to the crowned hole 8 into which the flat cylindrical body 4 of the belt passing main body 1 is inserted and the retaining projection 7. A locking recess 9 having a wide width is formed, and operation streaks 10 are formed on both sides in a knurled shape.

The main body 1 for belt passing and the outer casing 2 for operation configured as described above are joined together by covering the main body 1 for belt passing with the outer casing 2 for operation. And one end of the belt B in the state where the
After passing through the belt passage 3, the belt is detoured to a belt ring C provided for eyeglasses and the like, again passed from the belt passage 3 to the crowned hole 8 to adjust the wearing length, and when the length is determined, the operation is performed. When the outer cylinder for use 2 is slid in the direction in which the bulging portion 5 of the pressing elastic body 6 is pressed, the free end of the pressing elastic body 6 projects into the belt passage 3 and presses and fixes the belt surface in the superposed state. When the operation outer cylinder 2 is slid in the direction opposite to the above, the belt pressing by the pressing elastic body 6 is released, and the length of the belt B can be freely adjusted.

[0011]

As described above, the fixing device for adjusting the length of the wearing belt according to the present invention is provided on one flat surface of a flat cylindrical body having a belt passage through which the end of the wearing belt of underwater glasses or the like reciprocates. A belt passing main body integrally formed with a cantilever-shaped pressing elastic body whose outer surface bulges in a belt passing direction and whose free end bends and protrudes into the belt passage by pressing of the bulging portion; An operation outer cylinder that is covered by the threading main body and presses the pressing elastic body by sliding movement in the belt passing direction, one end of the belt passed through the belt main body,
The free end of a pressing elastic body that is folded back by a belt passing ring or the like formed in underwater glasses or the like and passed again through the belt passing main body, and the belt in the superimposed state in the belt passing main body is bent by sliding movement of the operation outer cylinder. Because it was pressed and fixed at the part,
The structure is simple, it is easy to manufacture and assemble, and it is a simple operation to slide the operation outer cylinder slidably covered on the belt passing main body,
It is possible to provide a low-cost fixing device for adjusting the length of the mounting belt, which can surely adjust and fix the length.
