Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to underwater goggles, and particularly to an improvement in the belt length adjustment mechanism.

FIG. 4 is a plan sectional view of one eyeglass body 41 of a conventional underwater goggle. Glasses body 41
A belt passage hole 41c is formed at the outer corner side (ear side) end of the frame portion 41a, with a single pillar 41b vertically formed approximately in the center. Gaps 41d, 41d between the side edge of the belt passage hole 41c and the pillar 41b
The inner dimensions of the belt 42 made of a flat rubber string are
It is assumed that the thickness is about the same as that of . The belt 42 is fixed to the eyeglass body 41 by passing its end through the outer (ear side) gap 42e from the back side to the front side, and the inner (inner corner side) gap 41d from the front side to the back side.
The length of the belt when worn is adjusted by the length of the end of the belt passing through the belt passage hole 41c.

FIG. 5 is a plan sectional view of the glasses body of another conventional goggle, and FIG. 6 is a front view thereof. A belt passage hole 51b is formed on the outer side of the frame portion 51a of the eyeglass body 51 and the portion extending from the frame portion 51a. Unlike the one in FIG. 4, the belt passage hole 51b has two
Book pillars 51d and 51c are formed, thereby forming three gaps 51e, 51f, and 51g. The outermost frame portion of the belt passage hole 51b is cut out at the center in the vertical direction, and a cutout portion 51h is formed. has been done. Further, a boss 51i is formed in a portion of the outer column 51c that faces the notch 51h. In this conventional example, the end portion of the belt 52 is threaded through the innermost gap 51e from the front side, and is passed through the outermost gap 51g from the front side to the back side. Then, the central part of the belt is inserted into the outermost gap 51g from the notch 51h,
It is designed to rotate to the rear. The length of the belt is adjusted by the length of the end of the belt passing through the belt passage hole 51b.

In addition, although not specifically shown, there is a gap similar to the one before on the outside of the frame of the glasses body, the belt is passed through this gap, the end side and the center side of the belt are passed through the buckle, and the buckle is passed through the gap. The length of the belt can be adjusted by adjusting the length of the belt.

[Problems to be solved by the invention] It is necessary to adjust the size of the belt to match the size of the user's head, but in the conventional structure as described above, when adjusting the size, the belt 42, 52
It requires strong fingertip force to pull out the belt from the belt passage holes 41c and 51b, and adjustment is troublesome. In addition, the rubber strap of the belt appears on the front side of the glasses, making it undesirable in terms of design.

[Means for solving problems]

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the underwater glasses eliminate the above-mentioned drawbacks by attaching a piece to the belt in a variable relative position and engaging the piece with the main body of the glasses. The purpose is to provide

The underwater goggles according to the present invention are constructed by connecting belts made of elastic material to both ends of the glasses body so that they can be fixed at arbitrary positions, and there is a gap in one side of the plate in which the end of the belt should be inserted. The glasses are characterized in that a bridge is provided, and a bridge engagement hole is formed in a side end portion of the eyeglass body to detachably engage the bridge.

Further, the bridge is formed by providing a pillar on one side of the plate at an appropriate distance from the pillar, and when the bridge is engaged with the eyeglass body, the bridge and the surface of the eyeglass body are flush with each other.

〔Example〕

The present invention will be described in detail below based on an example of goggles.

Fig. 1 is an exploded perspective view of underwater glasses according to the present invention (hereinafter referred to as the proposed product), Fig. 2 is a perspective view of the assembled state, Fig. 3 is a plan sectional view of one side of the glasses body, and Fig. 7 is FIG. 8 is a perspective view showing the piece engagement hole cut away with the piece removed from the piece engagement hole, and FIG. 8 is a partially enlarged sectional view showing the engagement portion between the piece engagement hole and the piece in FIG. 3. . The rectangular synthetic resin piece 1, whose vertical dimension is slightly longer than its horizontal dimension, has a thickness of 1.5 mm and a horizontal length of approximately
A piece post 1b extending in the vertical direction is formed at the center of the back side of a substantially rectangular piece plate 1a with a vertical length of about 10 mm and a vertical length of about 15 mm, with a gap 1c narrower than the thickness of the belt 3 separating the piece plate 1a. . The belt 3 is made of a flat rubber string similar to the conventional one. Frame 2 of the glasses body
On the outside (ear side) of a, there is a vertically elongated belt insertion hole 20a with a width slightly narrower than twice the thickness of the belt 3 and slightly longer than the width of the belt 3, and a piece 1 is inserted into the frame on the front side. A piece engaging hole 20 is formed which includes a recess 20b into which the piece 20 is fitted so as to be flush with the piece 2a. This piece engagement hole 20 has first, third,
As is clear from Figures 7 and 8, the piece pillar 1b of piece 1 is placed, and the belt 3 located on the back side of the piece is placed.
Moreover, as described above, tapered surfaces 20c and 20d are formed on both sides of the recess 20b in the lateral direction so that the recess 20b can be engaged and fitted flush with the frame 2a. It is made thinner by the thickness of the piece board 1a.

On the back side of the frame 2a of the glasses body 2, there is a pad 2b.
is attached. Further, a bracket 2c is formed at the inner corner side end of the eyeglass body 2, into which a connecting member 4 made of soft synthetic resin for connecting the left and right eyeglass bodies 2 is inserted. By changing and adjusting the engagement position between the connecting member 4 and the bracket 2c, the dimension between the glasses bodies 2 can be adjusted.

In this product constructed as described above, the belt 3 is inserted from one side into the gap 1c between the piece plate 1a and the piece post 1b with the belt 3 passed from the back side to the front side of the belt insertion hole 20a from the end thereof. , adjust the insertion length appropriately, and insert the inserted end into the belt insertion hole 20a.
The piece 1 is assembled by passing it from the front side to the back side, pulling the belt 3 from the back side, and fitting the piece 1 into the piece engaging hole 20.

This completes the connection of the belt 3 and the bridge 1 to the glasses body 2. When this is worn on the head, the longer part of the belt 3 (center side) presses the shorter part of the belt 3 between the outermost edge of the back side of the glasses body 2, and the belt 3 can be moved to any position. The belt 3 will not come off from the piece 1 or the piece 1 will not come off from the glasses body 2. To adjust the length of the belt, push the belt 3 from the back side or raise the front piece plate 1a from the outermost part and insert the piece 1 into the piece engaging hole 2.
0, adjust the insertion length of the belt 3, and fit the piece 1 into the piece engagement hole 20 again as described above.

〔effect〕

In the case of the present invention as described above, when adjusting the length of the belt, the piece 1 is attached to the eyeglass body as described above.
It is only necessary to remove the belt 3 from the belt and pull it to one side, and the length can be adjusted quickly and without requiring strong fingertip force. In other words, the conventional one has a simple structure.
Even with the belt shown in the figure, strong fingertip force is required to pull the belt to one side, which takes time, and it is necessary to pull the belt to the other side. It's easy to do.

Also, since the rubber string does not appear on the front side of the glasses,
The present invention has excellent effects such as being able to create a beautiful design on the surface side. The present invention is not limited to goggles, but can also be applied to underwater glasses that cover both eyes with a single frame.
