Description

[Technical Field]

[0001] The present invention relates to blown eyeglasses having a lightweight and strong structure. [Background technology]

[0002] Conventional 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 widely known to be produced and sold by many eyeglass frame manufacturers and widely used by users as vision correction devices and fashion items. For example, as shown in Non-Patent Documents 1 and 2, conventional brow glasses have a distinctive thick design at the top of the frame.

[0003] 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 introduced in magazines and fashion magazines. As a result, although the design of brow glasses is introduced 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.

[0004] 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) and (D) on either side of (C). A metal rim (E) is attached to the underside of the brows (C), and the (E) is fitted into a groove formed in the lower part of the side of (C), and nose pads (F) and (F) are attached to the inside (center) of the (E).

[0005] Figure 6(b) shows the back 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).

[0006] The method of fixing the plastic blow (ha) and metal rim (ho) is to form 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 screw horizontally into the screw holes (ri) drilled in the plastic blow (ha) to fix the metal rim (ho) to the plastic blow (ha).

[0007] 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 proportion of metal in 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.

[0008] 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 conventional brow glasses to slip down, shifting the focus of the lenses 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 conventional brow glasses once when they purchase them, they are prone to slipping or loosening during use. This means that users cannot always wear them comfortably.

[0009] The temples (C) can be folded via hinges (G), but the spectacles are put on and taken off with the temples (C) open.

[0010] The temples are adjusted to fit the shape of the ears, and the tips of the temples are bent inward, so unless stress is applied to the temples and they are expanded beyond the limit of the hinge, the tips of the temples will hit the face and the glasses will not be able to be put on or taken off.

[0011] When putting on or taking off the glasses, load is transmitted from the temple (C) to the hinge (D), and then from the hinge (D) to the front part (I). This load is then concentrated on the four thin screw holes (R) on the back of the plastic blow (C) of the front part (I), which can cause fatal damage.

[0012] 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 glasses, the rim material is changed and the method of fixing the brow and rim is improved. This new structure allows users to wear brow glasses more comfortably for a long period of time. [Prior art documents] [Non-patent literature]

[0014] As described above, conventional brow glasses have the above-mentioned problems. This problem is the problem that the present invention aims to solve, and it aims to provide brow glasses that are lightweight and have a strong structure. [Means for solving the problem]

[0015] The brows, rims and temples of the brow glasses according to the present invention are made of plastic.

[0016] In the present invention, a groove is formed in the lower part of the side surface of the blow, and a vertical screw hole is drilled in the upper part of the side surface of the blow.

[0017] Form an attachment plate that fits into the groove at the bottom of the side of the blower and drill screw holes.

[0018] Next, 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 brow sides, and insert screws into the screw holes to secure the rim to the brow. [Effects of the Invention]

[0019] The brow glasses of the present invention have brows, rims, and temples made of plastic, significantly reducing the amount of metal used compared to conventional brow glasses. This reduces the overall weight of the glasses, including the weight of the lenses, and prevents the glasses from slipping down or the lenses from losing focus. Furthermore, the absence of nose pad marks improves the wearing comfort of brow glasses.

[0020] By the way, if the plastic used in these brow glasses is made of acetate, a type of plastic, the specific gravity of acetate is 1.32, making it possible to significantly reduce the weight compared to conventional brow glasses and minimize the amount of metal used.

[0021] In the present invention, the screws embedded in the attachment plate and rim absorb the load transmitted from the temples and hinges to the front part, strengthening the structure of the brow glasses.

[0022] The attachment plate also serves to connect the brows and rims, improving durability. Furthermore, the brows and rims are fastened together by drilling screw holes in the upper part of the thick plastic side of each brow and rim, and inserting screws to fasten the rims to the brows. This method improves the strength and durability of brow glasses.

[0023] As described above, according to the present invention, it is possible to provide blown eyeglasses having a suitable structure that is lightweight and strong. [Brief explanation of the drawings]
