Description

The present invention relates to blown glasses that are lightweight and have a strong structure.

Traditional brow glasses, also known as thermont glasses, are called "brows" because the upper part of the frame is thick and shaped like an eyebrow. They are produced and sold by many eyeglass frame manufacturers, and are widely used by users as both vision correction devices and fashion items. For example, as shown in Non-Patent Documents 1 and 2, conventional brow glasses frames have a distinctive thick design at the top of the frame.

Although there are many differences in the design of the above-mentioned brow glasses, their basic structure has remained almost unchanged since their creation. As a result, there are no detailed technical documents, and their designs are mainly featured in magazines and fashion magazines. As a result, while the design of brow glasses is featured in many magazines, their structure and technical details are not recorded in literature. For example, as shown in Non-Patent Document 1, even specialized books on glasses only contain simple diagrams and short explanations.

Figure 6 (a) shows a front view of a conventional brow eyeglass frame. The front part (A) has a bridge (B) in the center, plastic brows (C) on either side of (B), and end pieces (D) on either side of (C). A metal rim (E) is attached to the underside of the brows (C), and (E) fits into a groove formed in the lower side of (C), and nose pads (F) and (F) are attached to the inside (center) of (E).

Figure 6(b) shows a rear view of a conventional brow eyeglass frame. Hinges (G), (G) are embedded or riveted into the end pieces (D) of the front part (A), and temples (H), (H) are attached so that they can be folded via the hinges (G).

The method for fastening the plastic blow (ha) and metal rim (ho) is to create a groove in the lower side of the plastic blow (ha), drill screw holes (ri) in two places on the inside and two places on the outside where the thickness of the plastic blow (ha) is thin, fit the metal rim (ho) into the plastic blow (ha), and fasten horizontally with screws into the screw holes (ri) drilled in the plastic blow (ha), thereby fastening the metal rim (ho) to the plastic blow (ha).

Traditional brow glasses have gained a certain level of popularity due to their distinctive design, but there are problems with their structure. Traditional brow glasses are heavy due to the high metal content of their structure. For example, if sun platinum is used as the metal material, the specific gravity of sun platinum is 8.67, making the brow glasses very heavy.

Furthermore, because glasses always contain a set of lenses, the weight of the lenses is added to the weight of the frame, increasing the overall weight of the glasses. This causes traditional brow glasses to slip down, causing the lenses to lose focus and affecting vision. Furthermore, their weight can cause ear pain and leave marks where the nose pads touch the skin. Even after users have adjusted traditional brow glasses once when they purchase them, they are prone to slipping or loosening during use. This means that they are not always comfortable for users.

By the way, the temples (C) can be folded using hinges (D), but the brow glasses are put on and taken off with the temples (C) open.

These temples are adjusted to fit the shape of your ears, and the tips of the temples are bent inward, so unless you put pressure on the temples and expand them beyond the limit of the hinge, the tips of the temples will hit your face and you will not be able to put on or take off the glasses.

When putting on or taking off the glasses, stress is transmitted from the temples (C) to the hinges (D), and then from the hinges (D) to the front section (I). This stress is then concentrated on the four thin screw holes (R) on the back of the plastic blow (C) of the front section (I), which can cause fatal damage.

This invention provides a new structure to solve the problems of conventional brow glasses. Specifically, in order to reduce the weight and increase the strength of brow-style eyeglass frames, the rim material is changed and the method of fixing the brow and rim is improved. This new structure allows users to wear brow-style eyeglasses more comfortably for longer periods of time.

As such, conventional brow glasses have the problems described above. This is the problem that the present invention aims to solve, by providing brow glasses that are lightweight and have a strong structure.

The brows, rims, and temples of the brow glasses of the present invention are made from plastic.

In the present invention, a groove is formed in the lower part of the blow side, and a vertical screw hole is drilled in the upper part of the blow side.

Form an attachment plate that fits into the groove on the bottom side of the blower and drill screw holes.

Furthermore, embed screws into the upper part of the left and right rim sides. Then, fit the attachment plate and rim into the grooves at the bottom of the left and right blow sides, and insert screws into the screw holes to secure the rim to the blow.

The brows, rims, and temples of the brow glasses of the present invention are made from plastic, significantly reducing the amount of metal used compared to conventional brow glasses. This makes the overall weight of the glasses, including the weight of the lenses, lighter, and prevents the glasses from slipping down or the lenses from going out of focus. Furthermore, since no nose pads leave marks, the wearing comfort of brow glasses is improved.

By the way, if the plastic used in these brow glasses is made from acetate, a type of plastic, the specific gravity of acetate is 1.32, making them significantly lighter than conventional brow glasses and minimizing the amount of metal used.

In this invention, the attachment plate and screws embedded in the rim absorb the load transmitted from the temples and hinges to the front section, strengthening the structure of the brow glasses.

The attachment plate also serves to connect the brows and rims, improving durability. Furthermore, the brows and rims are secured together by drilling screw holes into the upper part of the thicker side of the plastic on both the left and right brows and rims, and then inserting screws to secure the rims to the brows. This method improves the strength and durability of brow glasses.

As explained above, the present invention makes it possible to provide blown eyeglasses with an ideal structure that are lightweight and strong.

Nose pads 6 are glued to the inside (center) of the rim 5 below the brow 3. Hinge 7 is embedded or riveted into the end piece 4, and temples 8 are attached via the hinge 7 so that they can be folded.

A groove 10 is formed in the lower part 9 of the blow side surface, and vertical screw holes 12a are drilled in the upper part 11 of the left and right blow side surfaces.

An attachment plate 13 is formed from aluminum plate to fit the groove 10 on the lower part of the blow side surface 9, and a screw hole 12b is drilled.
