Description

[Detailed Description of the Invention] This invention relates to an improvement in windshield glasses used by motorcycle riders, skiers, hang gliders, and the like.

Generally, this kind of glasses is used only to function as glasses, and ear caps are worn separately when earphones are needed for protection from the cold in winter or for communication purposes. things are being done. However, the glasses fixing device and the ear cap fixing device end up surrounding the head doubly, making it difficult to put them on and not necessarily providing a comfortable feeling of use. In addition, when wearing ear caps, there are individual differences in the depth from the face to the ear position, the relative position between eye level and ear height, and the angle formed by the surface that covers both ears. It has been extremely difficult to place the ear cap on the ear at the optimum position and angle.

The purpose of this invention is to eliminate the above-mentioned problems and provide glasses that serve as windshield glasses and ear caps, and that have a comfortable feel and appearance regardless of individual head shapes. shall be.

To explain the embodiment, reference numeral 1 denotes a frame of eyeglasses, and a windshield lens 2 made of transparent synthetic resin or the like is detachably held on the inner surface of the frame. Reference numeral 5 designates an ear cap, in which a concave groove-shaped guide 5c with a semicircular cross section is formed in the center of the interior of a synthetic resin bowl-shaped cap 5b with a heat-insulating fluff body 5a provided on the opening side.
An elastic locking piece 5d is provided between the cap and the cap with a gap between the clips, and a shaft hole 5e facing in the guiding direction of the guide 5c is opened in the peripheral wall of the cap 5b. 5f indicates a decorative lid of the cap 5b, and 5g indicates a sound opening.

A large number of parallel circumferential grooves 7 are formed in the lower half of the locking shaft 6 that can be inserted into the inside of the cap 5b from the opening 5e, while the upper portion of the locking shaft 6 is bendable to incline the locking shaft 6 inward. A flexible portion 4 is formed. The other end of the flexible portion 4 is provided with a small disk 8 having a short shaft 9 with a head protruding from the center and a small protrusion 10 formed at an eccentric position, which is inserted between the frame 1 of the glasses and the ear cap 5. The elastic connecting device 3 is as follows.

Next, at both ends of the frame 1 of the glasses, a hole 14 that fits into the short shaft 9 is provided in the center, and a disk part 11 is formed with conical recesses 12 of equal pitch arranged on a concentric circle. The short headed shaft 9 of the connecting tool 3 is pivoted into the hole 14 through a notch 13 provided in a part of the disk portion 11 by force-fitting.

In the embodiment, the frame 1 is provided with an appropriate number of protrusions 15 for attaching the windshield lens on its inner periphery, and the mounting hole 21 in the center of the semicircular ear 22 provided on the upper edge of the windshield lens 2 is used as the protrusion 15. engage.

In addition, there is a band stopper 16 that can be attached to and detached from the frame 1.
For example, an upper jaw 17 and a lower jaw 18 are provided in a C-shaped cross section,
Further, on the opposite side of the jaw of the band stopper 16, a presser piece 19 having an opening 23 on one side and forming a gap 20 is formed, and the presser piece 19 is provided with an elastic band B.
Connect the holes _B1 at both ends.

The configuration of the present invention is as described above, and the ear cap 5 has the concave groove guide 5c of the cap 5b and the elastic locking piece 5d engaged with the parallel circumferential groove 7 of the locking shaft 6 in the connecting tool 3, and and the circumferential groove 7 and the locking piece 5
They are fitted in a so-called click-stop manner so that the engagement position of d can be changed, so that they can move freely in the axial direction and freely rotate about the shaft. Further, the short shaft 9 at the other end of the connecting tool 3 is pivotally connected to the hole 14 of the disk part 11 at the end of the frame 1, and the small protrusion 10 of the small disk 8 of the connecting tool 3 and the frame 1
Due to the engagement with the conical recess 12 of the disc part 11 at the end, the frame 1 is closed at a so-called click stop.
The angle α of the locking shaft 6 of the connecting tool 3 can be finely adjusted. Furthermore, the ear caps 5 can freely rotate around the locking shaft 6, and the flexible portions 4 cause the ear caps 5 to incline inward, so that the ear caps 5 can be adjusted in accordance with the distance between both ears on the head. The spacing changes elastically,
Both ears can be pressed with moderate pressure. Therefore, the soft hair a on the inner surface of the ear cap 5 is adjusted depending on the relative position of the eyes and ears, the depth from the face to the ears, the distance between the ears, and the angle formed by the plane containing the surfaces of both ears. It is possible to make it fit completely into the ear. This solves the problem of having to wear ear caps separately from the glasses as with conventional windshield glasses, and also allows for changes in the shape of the head, especially the relative position of the eyes and ears, and the angle of both ears. This has the effect of providing an ear cap that can cover the ears in an optimal state regardless of individual differences, and is comfortable to use.

The windshield lens 2 has ears 22 and mounting holes 21 provided on its upper edge, and projections 15 provided on the inner periphery of the frame 1, which fit together. Can be exchanged depending on shape.

Furthermore, if two band stops 16 are used to connect both ends of the elastic band B through the presser piece 19 and the opening 23 and the band is hung on the back of the head, the effect of preventing the glasses from falling off is produced.
