Description

[Detailed description of the invention] eye shield TECHNICAL FIELD This invention relates generally to eye sunscreens, and more particularly to sunshades that can be worn in place of sunglasses and are relatively suitable for use in sunglasses. This article relates to new light-shielding glasses that are lightweight and inexpensive.

The well-known visor-type parasol, such as that provided on paralyzed hats, protects the sun from Protect your eyes from direct glare from high elevations, but avoid exposure to water or snow. They provide no protection against reflected glare such as Form paralysis also does not provide adequate protection when the sun is low. Therefore, Wearing sunglasses to protect against glare under these adverse conditions It is often necessary to However, sunglasses are generally made of thin, lightweight metal frames. It also has a moderate mass in the case of a type with a lens and a plastic lens. Even the least expensive of these lightweight sunglasses is still moderately expensive. sangu In terms of the mass of the lath and the loose retention system, they are suitable for trials in snow. It is not particularly suitable for strenuous activities, and if worn on a boat, it will It is a victory that is lost to the outside.

The present invention includes a worn strip of semi-rigid transparent material; The lip has a light-shielding part located in the center, and the lip is located approximately in the center of the light-shielding part and a nose pad formed on the lower longitudinal edge and a pair extending from each end of the light-shielding portion; by a wing portion of the strip and one or more pleats extending generally across the strip. Each window mirror includes a divided portion of each wing portion and a light shielding portion.

Embodiments of the present light-shielding glasses preferably consist of the upper edge of the strip from the forehead. On the other hand, another embodiment also includes a device in which the thin edges of the strip do not cause discomfort. It is desirable to include a device that distributes the weight of the eyeglasses on the wearer's nose, so that Yes. Generally, nose pads are designed to be removed.

The device for attaching the light-blocking glasses to the wearer's ears should preferably be located at the distal end of each wing. It is desirable to include a loop formed and adapted to fit over the wearer's ear. one Generally, the front portion of each loop is formed as part of a strip of transparent material. on the other hand, the rear part of the loop should be sufficient to conform to the contours of the ear and avoid discomfort. It is made of a resilient material that has a large surface area.

The strips are generally made of acetate film or polyvinyl chloride (PVC) film. a strip of film, in a preferred embodiment, hot pressed and A strip of polished transparent PvC film with a thickness of around 200μ It's a lip.

Preferably, the device consists of a strip attached to the wearer's forehead. A cross-linked polyester film approximately 4 layers thick and 14 layers wide is attached along the top edge of the light-shielding area. Preferably a strip of tyrene 4 μ, placed after the ear loop. The side portions should preferably also consist of cross-linked polyethylene foam. desirable.

Preferred embodiments of the invention will now be described with reference to the accompanying drawings.

FIG. 1 is a front perspective view of a preferred embodiment of the present invention, and FIG. 2 is a rear view of the light-shielding glasses shown in FIG. Perspective view, Figure 3(2), Figure 3(C), Figure 3(0), and Figure 3@ are respectively A rear view, a front view, a top view, and an end view of the light-shielding glasses of the first cause, Figure 4 is a diagram from Figure 1 showing the relative positions of the foam forehead part and eyepiece piece with broken lines. FIG. 4 is an exploded view of a blank sheet forming the embodiment of FIG. 3;

Here, FIG. 1, FIG. 2, and FIG. 3 will be explained. Preferred embodiments of the invention includes an inexpensive, lightweight, disposable blackout+U mirror that can be worn in place of sunglasses. , these light blocking glasses are mostly made of colored acetate or PVC film. acetate or PvC film cut or treated from a sheet of Formed as a strip of 0. This material is preferably hot pressed. A polished 200μ PvC film is preferred.

The light-shielding portion 11 of the strip 10 has a substantially rectangular shape and is located approximately in the center of its lower edge. It has a recess 12 forming a nose pad. Each strip slopes downwards The wing portion 14 has a plurality of substantially parallel folds at the tip of each end of the light shielding portion 11. 13 and an ear loop 15 formed at the distal end of each wing portion. and these loops connect to the distal part of the strip @16 and the elastic attached to it. loops 17 of foam material. Foam material should preferably be , cross-linked polyethylene foam is preferred. These ear loops are blackout lI ! To hold the mirror in place, place the foam part of each luniform behind each ear. It is designed to be placed over the wearer's ear.

As a result of the relatively light weight of the light-blocking glasses1 and the secure way in which they are held over the ears, Preferred embodiments of the invention are suitable for use when the wearer is engaged in a relatively strenuous activity. They are suitable for use in environments where regular sunglasses are inconvenient.

The light-blocking glasses are spaced away from the wearer's forehead, so that the top edge of the light-blocking glasses is on the forehead. To avoid possible discomfort due to contact and rubbing, the rear side of the light-shielding part 11 A strip 18 of cross-linked polyethylene foam is also provided over the top edge of the It will be done. This spacer also helps keep the light-blocking glasses away from the eyes and eyelashes, making them even more inconvenient. It also helps to ensure that pleasure is avoided.

Due to the nature of the acetate or PVC film material, the pleats 13 have some degree of elasticity. When physically compressed or expanded, the light-shielding portion 11 and the ear loop The distance between can be adjusted accordingly. Roughly, the upper area of the pleat is compared to the lower area of the pleat. Stretching allows the wing to be lowered relative to the shaded area, while the folds The extension of the lower area of the pleats relative to the upper area is the bring about positive results.

In another embodiment (not shown), the nasal cavity 12 can be provided with a foam. This increases the area over which the nasal recess 12 engages with the wearer's nose.

Now, FIG. 4 will be explained. The figure shows the strips before being piled up according to the dashed line. The developed shape of the strip 10 is shown, and from this figure it can be seen that the wing portion 14 of the strip 1o is The downward slope with respect to the light section 11 and the fact that the pleats MA13 are at the center of the strip. It can be seen that it is almost parallel to the line. Foam ear loop 17 and foam forehead The position with respect to the spacer 18 is also shown by a broken line.
