Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to goggles with interchangeable lenses.

(Prior art) There are monocular and binocular types of goggles, and some sealed goggles for swimming have a structure in which the entire eyecup ring can be bent and replaced (for example, −182322).

However, in the case of goggles having the above structure, it is not enough to replace only the lenses, but the entire eyecup must be replaced, which is wasteful. Additionally, because the eyecups are structurally connected to each other at a joint in the middle, it is necessary to remove the connecting joint when changing lenses. Since the joint is connected by its elasticity, it is troublesome to attach and detach, and there is also the problem that the lens-side connecting piece is easily broken.

(Technical Issues) This invention solves the above-mentioned drawbacks and problems.The issues are that only the lens body can be replaced, the lens body can be attached and detached very easily, and it can be supplied at a low cost. The purpose is to do so.

(Technical means) In order to solve the above problems, the present invention provides a lens body 1
0 is provided with a pair of left and right lens attachment ports 21 on the eyeglass frame 20 for attaching the lens. The eyeglass frame 20 is provided at both left and right ends of the body so as to protrude rearward, and means 30 for wearing on the face are provided at both left and right ends of the eyeglass frame 20, respectively.

(Example) To explain with reference to the drawings below, the lens body 10
The eyeglass frame 20 to which the eyeglass frame 20 is attached has a pair of left and right lens attachment openings 21, and engagement edges 22, 23 extending in a generally vertical direction are provided at both left and right ends of the attachment openings 21.

The lens body 10 is almost entirely composed of only a transparent lens part, and has a side viewing part 1 outside the central lens part 13.
4 are continuous via the bending part 15, and the left and right ends of the lens body are brought into contact with the front surface of the environmental frame in accordance with the curved shape of both wings of the eyeglass frame. Reference numeral 16 indicates the inner side, and 17 indicates a small gap on the back side of the bent portion to maintain ventilation. Side viewing portions 14 on both left and right sides of this lens body 10
At the end of the inner part 16, there are engaging parts 11 and 12 provided so as to protrude rearward, and the engaging part 1
1 and 12 are removably engaged with the engagement edges 22 and 23 of the eyeglass frame 20. The engaging parts 11 and 12 are parts that protrude from the lens body, and the engaging parts can be provided with recesses 11' and 12' for receiving the engaging edges 22 and 23. Since both the engaging parts 11 and 12 are separated from the lens part 11, there is an advantage that precision can be improved even with a molded lens.

The means for wearing on the face 30 may be of a belt type, but the example shown is an example using a pair of ear-hook type temples 31 on the left and right. The temple 31 has a thin hinge 32 for bending at the mounting portion, and a mounting piece 33 on the proximal end thereof is inserted into a vertical slit-shaped mounting opening 34 formed at both left and right ends of the eyeglass frame. , it has a structure that is fixed to the temple 31 after being folded back with a hinge.
Reference numeral 35 indicates a pin having a swollen head for fixing provided on the mounting piece 33, and 36 indicates a fixing hole formed on the temple side for fitting the pin. Note that 40 indicates a nose pad, but in addition to using a belt as a means of wearing it,
You can use any shape you need. 41 indicates a central protrusion.

The above lens body 10 is made of transparent synthetic resin.
We will prepare a variety of products that are manufactured, colored, or dioptrically corrected, depending on your choice. The eyeglass frame 20 may be made of synthetic resin, various types of rubber, metal, or the like and may have any design.

(Operation of the invention) In the above structure, the various lens bodies 10, the various eyeglass frames 20, and the various wearing means 30 are manufactured separately, and are used in combination as appropriate. At this time, the lens body 10 is removably engaged with the engaging edges 22, 23 on the left and right sides of the attachment opening 21 of the eyeglass frame 20 using the engaging portions 11 and 12 that protrude rearward, so that the lens body 10 can be attached and detached. Replacement is very easy. That is, each lens body 10 has two engaging portions 11, 1 on the left and right.
2 engages with the engagement edges 22 and 23 of the attachment opening, so it can be attached and detached with one touch.

(Effects of the invention) As described above, according to the invention, it is possible to select and assemble the desired eyeglass frame 20 and lens body 10 at a store, and also to purchase several kinds of necessary lens bodies, for example, for myopia. You can purchase lens bodies with prescription correction, dark and light shades of sunglasses, prescription sunglasses, etc., and use them without any problems by changing the lenses as necessary when wearing them.

Therefore, according to the present invention, only the lens body can be replaced, which is economical, and when changing the lens, the lens body can be attached and removed with one touch, so there is no risk of damaging the lens. It can be supplied at a low price.
