Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to hydroscopic glasses.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, there is a known technique for forming a pair of water glasses with a lens member made of a transparent material, a pad made of a flexible material such as sponge, and a wearing band worn around the head. Further, in order to attach the pad to the lens member, a technique of providing a flange on the outer periphery of the lens member and providing a groove portion on the pad to press fit the flange and the groove portion is publicly known or well known. No. 42306 can be cited.

[0003]

[Problems to be solved by the device]

 When the pad is attached to the lens member by pressing and fitting the flange and the groove as in the prior art, the pad can be attached to and detached from the lens member, which facilitates pad replacement. . However, in the case of children's underwater glasses, the elasticity and shape of the groove is impaired when the child repeatedly attaches and detaches the pad, and the watertightness between the groove and the flange cannot be maintained. There is a problem that it becomes easy to come off. If the flange and the groove are adhered, there is a problem in that the original pad exchange function is lost.

Therefore, in the present invention, the pad is clamped by the first locking portion provided on the lens member and the annular frame member that is separate from the first locking portion to make it difficult to remove the pad, and the pad can be removed when necessary. The problem is to solve the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 The points that this device uses as means for solving the above problems are as follows.

This invention is premised on hydropic glasses including a lens member, a flexible pad, and a wearing band.

Under such a premise, a first locking part extending in the circumferential direction of the outer periphery of the lens member and a second locking part located on the front end side of the lens member with respect to the first locking part are provided, and The front edge of the lens member is brought into contact with the first engaging portion of the pad formed in the above-mentioned manner by fitting the annular frame member from the front end of the lens member and engaging the frame member with the second engaging portion. The peripheral edge of the pad is clamped between the first locking portion and the withdrawal in the direction, and the frame band member is provided with the attachment means for attaching the wearing band so that it can be worn on the face. That is the feature of this device.

[0008]

[Action]

 In the hydroskeleton thus constructed, the peripheral edge portion of the pad is brought into contact with the first locking portion provided on the outer periphery of the lens member from the outside, and then the annular frame member is fitted from the front end of the lens member to (1) The pad can be hard to be removed by holding the peripheral portion of the pad together with the locking portion. When the peripheral edge of the pad is covered with the frame member, the pad cannot be touched, and the pad cannot be removed unless the frame member is detached from the lens member. By engaging the frame member with the second locking portion, it is possible to prevent the lens member from being pulled out toward the front end direction.

【Example】

 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, a frame member 3 and a pad 4 in the left eye of the wearer are shown separately. The underwater glasses 1 include a pair of left and right substantially oval lens members 2 made of transparent hard plastic, a frame member 3 made of hard plastic fitted into each of the members 2, and a sponge rubber which is pressed against the wearer's face. A pad 4 made of a flexible elastic material, a connecting band 5 made of semi-hard rubber connecting the left and right frame members 3, and a wearing band 6 made of soft rubber attached to the rear ends of the frame members 3. I am doing it.

FIG. 2 is a view taken along the line AA of FIG. 1, but showing the lens member 2 in a side view.

In FIGS. 1 and 2, the lens member 2 is a flat front see-through portion 10, a peripheral wall 11 extending rearward from the outer periphery of the see-through portion 10 toward the wearer's face, and a rear end of the peripheral wall 11. The peripheral wall 11 has a locking projection 13 with a triangular cross-section that extends toward the rear and a notch 12A of the flange 12 in the vicinity of the center of the underwater glasses 1 on the peripheral wall 11. There are extending locking grooves 14 and ribs 14A that cross the grooves 14. The flange portion 12 is a first locking portion for contacting the pad 4, and the locking projection 13 and the locking groove 14 are second locking portions for mounting the frame member 3.

The pad 4 is an annular member having a skirt portion 16, and an annular groove 17 provided on the inner side of the front end fits into the flange 12 and has a curved portion 18 at the rear end that adheres closely to the face. Further, a rib 17A that crosses the annular groove 17 is provided near the center of the spectacles 1, and a notch 17C is formed in an upper bottom 17B of the annular groove 17 which is described later.

The frame member 3 is also an annular member, and has a through hole 20 through which the see-through portion 10 of the lens member 2 can be inserted from the rear of the frame member 3, and a connecting band insertion hole 21 on the side near the center of the underwater glasses 1. It has a wearing band insertion hole 22 on the outer side. The inner circumference of the through hole 20 is slightly larger than the outer circumference of the peripheral wall 11 of the lens member 2 and smaller than the outer circumference of the flange portion 12, and the locking projection 13 of the lens member 2 is fitted to the center of the hydroscopic glasses 1. It has a possible locking recess 23, and has an edge portion 24 and a notch 24A of the edge portion 24 which can be fitted to the locking groove 14 of the lens member 2 and the rib 14A on the outer side. The pair of left and right frame members 3 are connected by a connecting band 5, and the connecting band 5 has protrusions 27 intermittently arranged on the inner side in the longitudinal direction and abuts the side edges of the through holes 21 from the inside to adjust the dimensions. It is installed as possible.

In the underwater glasses 1 constituted by these members, when the frame member 3 is fitted from the front of the lens member 2 in a state where the pad 4 is fitted in the flange 12, the locking protrusion 13 is locked. By fitting in the recess 23 and the bottom surface of the projection 13 abutting the bottom surface of the recess 23, the upper bottom portion 17B of the groove 17 of the pad 4 together with the flange 12 of the lens member 2 can be clamped in a compressed state. Further, on the outer side of the water glasses 1, the edge portion 24 and the notch 24A fit into the locking groove 14 and the rib 14A, and the upper bottom portion 17B of the pad 4 can be held together with the flange portion 12. At this time, by setting the engaging dimension of the engaging projection 13 and the engaging groove 14 to the engaging recess 23 and the edge 24 to a desired value, the frame member 3 from the front of the lens member 2 is set. Withdrawal can be suppressed with an appropriate strength, and the withdrawal can be freely or disabled. When the lens member 2, the frame member 3 and the pad 4 are fitted to each other, the locking projection 13 and the rib 14A of the lens member 2 are fitted to the locking recess 23 and the notch 24A of the frame member 3. And the notches 12A and the ribs 14A of the lens member 2 are fitted to the ribs 17A and the notches 17C of the pad 4 and serve as positioning means for each other.

The wearing band 6 is attached such that its free end can be adjusted in size by sequentially winding it around three support shafts 28 provided in the insertion holes 22 of the frame member 3. Therefore, when the underwater glasses 1 are worn, the tension applied to the wearing band 6 acts to bring the frame member 3 closer to the flange portion 12 and increase the clamping pressure on the pad 4. Since the outermost one of the support shafts 28 is divided at the central portion in the longitudinal direction, it is easy to hang the wearing band 6 (see FIG. 1).

[0017]

[Effect of device]

 Since the pad according to the present invention is sandwiched between the lens member and the annular frame member, even if a soft material is used for the pad, it is difficult to remove the pad.

When the frame member covers the peripheral edge where the pad contacts the lens member, it becomes impossible to directly touch the peripheral edge, and it becomes more difficult to remove the pad.

Since the wearing band is attached to the frame member, when wearing the underwater glasses, the tension of the band acts in the direction of increasing the clamping pressure on the pad, and there is no risk of the pad falling off.
