[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to underwater glasses used for diving and swimming.

[0002]

2. Description of the Related Art Conventionally, underwater glasses are composed of a pair of left and right lens members, a flexible connecting band made of rubber or the like for connecting the lens members at the nose of a wearer, and a wearing band attached to the lens member. Techniques for performing this are well known. For example, in Japanese Utility Model Publication No. 2-42306, locking projections are intermittently arranged in the longitudinal direction of the inner surface of the connection band so that the left and right ends of the band can be disengaged from the slits provided at the inner end of the lens member. The left and right lenses are inserted so that the distance can be adjusted.

[0003]

In the prior art including the above-mentioned known example, a connecting band made of a straight band material is curved, and both left and right ends thereof are provided in a lens member by a slit or other locking means. It is customary to hold by means. In this case, when the rigidity of the connecting band is high, the connecting band tends to return to the original straight state from the curved state, so that the left and right lens members are in contact with the wearer's face. It may not be aligned. FIG.
FIG. 9 is a side view of the underwater glasses 100 when the left and right lens members are not in such an aligned state, and the originally positioned straight connecting band 103 located at the center attempts to return to the straight state from the curved state; The lens member 102 stands upright so that the outer end portion thereof jumps up. In order to wear the underwater glasses 100, the connecting band 103 must first be curved as shown by the imaginary line to bring the lens members 102 into an aligned state, which is troublesome to wear and difficult to use. In children's underwater glasses, such a problem is particularly likely to occur because the distance between the left and right lens members is relatively small, and the force of the curved connecting band to return to the straight shape tends to be strong.

In view of the above, the present invention solves the above-mentioned problem of the prior art by providing means for contacting the outer surface of the connecting band at one end of the lens member on the center side of the spectacles so that the connecting band can be tilted inward. That is the challenge.

[0005]

Means for solving the above problems The present invention is as follows to solve the above problems.

[0006] This invention presupposes underwater spectacles comprising a pair of left and right lens members, a flexible connection band connecting the lens members at the nose of the wearer, and a wearing band attached to each of the lens members. It is.

[0007] Under such a premise, a locking means is provided at an end of the lens member on the center side of the spectacles to lock the connecting band at the end, and a contact means for contacting the outer surface of the connecting band is provided between the means. It is a feature of this invention that the connecting band locked by tilting can be tilted from the outer surface toward the inner surface.

[0008]

In the underwater glasses constructed as described above, the connecting band curved to connect the left and right lens members is tilted inward toward the inner surface by the contacting means against the outer surface, and returns to the original straight shape. Therefore, the left and right lens members can be kept in an aligned state as when they are in contact with the face.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the underwater glasses according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of the underwater glasses 1, in which a lens member 2 to be described later for the left eye of a wearer is exploded into constituent members. The eyeglasses 1 include a pair of left and right lens members 2.
And a connecting band 3 for connecting the lens members 2 at the center of the spectacles 1, that is, at the nose of the wearer, and a wearing band 4 attached to the outer end of the lens member 2 so as to be adjustable in length. The lens member 2 includes a frame member 5 made of hard plastic, a lens 6 made of transparent hard plastic,
Pad 7 made of a soft elastic material such as rubber or sponge rubber
Consists of

FIG. 2 is a view taken along the line AA in FIG.
The lens 6 and the connecting band 3 are shown in a side view. In the lens member 2, the lens 6 has a flat transparent portion 1 at the front end.
0, a flange portion 12 at the rear end, and these two portions 10, 1 at the outer end.
A fitting groove 14 extending in the circumferential direction in the peripheral wall 11 between the two,
And a locking projection 13 protruding from the peripheral wall 11 at the inner end. The pad 7 has a fitting groove 17 with the flange 12 at the front end,
At the rear end, there is a folded portion 18 that comes into contact with the wearer's face, and a skirt portion 16 between the two. The frame member 5 is provided with a see-through portion 10 for the lens 6 fitted with the pad 7.
A through hole 20 into which the see-through portion 10 can be inserted, a locking recess 23 into which the locking projection 13 fits into an inner end of a peripheral wall forming the through hole 20, and an outer end thereof Edge 2 fitted into groove 14A together with upper bottom 17A of pad 7
And 4.

Also, as shown in FIGS.
Has an engaging portion 25 on the inner end thereof, which allows the end of the connecting band 3 to be hung around.
Has a through hole 21 through which the band 3 can be inserted from the front, and a locking claw 26 which can contact the outer surface of the inserted connecting band 3 and tilt the band 3 from the outer surface to the inner surface. The locking claw 26 is a pair of claws facing each other in the width direction of the connection band 3, has a gap between the upper edge portion 30 of the through-hole 21 and the connection band 3, and has a facing engagement member. Tip 26A of each stop claw 26
Have a required separation distance to facilitate such insertion (see FIG. 1). Further, the frame member 5 has an insertion hole 22 for hanging the free end of the wearing band 4 around the outer end,
Three locking shafts 28 extending in the width direction of the band 4 in the hole 22, and the outermost locking shaft 28 is bisected at the center,
The band 4 is easily inserted.

The connecting band 3 is made of soft or semi-rigid rubber or plastic, and is a straight band having elasticity for restoring deformation. The connecting band 3 is elastically deformable in the longitudinal direction of the inner surface and can pass through the insertion hole 21. The locking projections 27 are intermittently arranged. In order to attach the connecting band 3 to the frame member 5, the band 3 is curved like an imaginary line, and each end is inserted into the insertion hole 21.
Is inserted into the lower opening 21B from the upper opening 21A, and the locking projection 27 at a required position is brought into contact with the edge of the lower opening 21B from behind (the lower side in FIG. 2) to make the position of the band 3 small. Subsequently, the band 3 is bent at the edge 30 of the upper opening 21A, and inserted between the edge 30 and the locking claw 26 from the gap between the tips 26A of the claws 26. The pair of left and right locking claws 26
It is in contact with the outer surface 34 of the band 3 between the left and right insertion holes 21.

FIG. 3 is a partial cross-sectional view illustrating an embodiment of the underwater glasses 1, but shows the connecting band 3 in a side view.
In this figure, the locking projections 27 are arranged in the longitudinal direction of the outer surface 34 of the connecting band 3, and one of them is brought into contact with the claw 26 from the side to position the band 3. The free end of the band 3 is inserted and locked into the insertion hole 21 to prevent the free end from obstructing the view in front of the underwater glasses 1.

In the illustrated example, the insertion hole 21 for the connecting band 3 is a through hole, but the present invention can be implemented by making this a blind hole.

[0016]

[Effect of the Invention] The underwater glasses according to the present invention are provided with a contact means to the outer surface of the connecting band, so that even when the straight connecting band is curved and used, it does not return to the original shape.
The same alignment state as when the left and right lens members are worn can be maintained, so that it is not necessary to wear glasses.
