Abstract
Description
[Technical Field]
[0001] The present invention relates to rimless eyeglasses that employ a structure in which metal is embedded inside plastic. [Background technology]
[0002] Referring to FIG. 1, typical rimless eyeglasses 1 are mainly composed of two lenses 10, one bridge 11, two end pieces 12, and two temples 13. Each lens 10 has a hole 100, 101 on each side, and the bridge 11 is disposed between the two lenses 10, with a hole 110 on each end of the bridge 11. A first screw 111 is inserted into the hole 110 in the bridge 11 and the hole 100 on the inner side of each of the two lenses 10, which face each other. The first screw 111 is then tightened with a first nut 112, thereby fixing the bridge 11 between the two lenses 10. Pads 113 are disposed below the bridge 11, facing each other, and the end pieces 12 are assembled and installed facing the outer sides of the two lenses 10. A hole 120 is provided at one end of the end piece 12, and a pin joint 121 is provided at the other end of the end piece 12. A second screw 122 is inserted into the hole 120 of the end piece 12 and the opposing outer hole 101 of the two lenses 10. The second screw 122 is then tightened with a second nut 123, thereby fixing the end piece 12 to the outside of the two lenses 10. The temples 13 are pin-connected to the pin joint 121 of the end piece 12 via a pin joint part 124, thus completing the structure of the rimless eyeglasses 1. However, because existing rimless eyeglasses 1 use screws and nuts to fix the bridge 11 and end piece 12 to the lenses 10, the screws and nuts of the assembly are prone to loosening over long periods of wear, which can cause discomfort to the wearer. This requires frequent retightening of the screws and nuts using tools, making assembly and use cumbersome. Furthermore, if the bridge, endpiece, and temples of existing rimless eyeglasses are made of metal to increase the overall structural strength, the eyeglasses will become heavy and less comfortable to wear. Conversely, if they are made of plastic, the eyeglasses will be lighter overall, but they will be prone to deformation, low strength, and breakage. Summary of the Invention
[0003] The main object of the present invention is to provide rimless eyeglasses that employ a structure in which metal is embedded inside plastic, thereby effectively improving the drawbacks of heavy overall weight and low strength.
[0004] The rimless eyeglass structure of the present invention is composed of two lenses, a bridge, two end pieces, and two temples. Two first perforations and two second perforations are provided on both sides of the lens, and a first plastic fixture and a second plastic fixture are provided on the inner surface of the lens, respectively. Two bushings protrude from each of the first fixture and the second fixture, and the two bushings of the first fixture are inserted into the two first perforations of the lens, and the two bushings of the second fixture are inserted into the two second perforations of the lens. The bridge is placed between the two lenses and is composed of a metal bridge inner body and a plastic bridge outer cover. Two first screws are provided on each end of the inner surface of the bridge inner body, and the two first screws are pressed into and engage with two bushings of the first fixing device. Two pad fixing devices extending rearward and downward are provided facing each other on the inner surface of the bridge inner body, and pads are assembled and installed in the pad fixing devices. A groove is provided on the inner surface of the bridge outer cover into which the bridge inner body is inserted. The two end pieces are attached to the opposing outer sides of the two lenses, and are composed of a metal end piece inner body and a plastic end piece outer cover. Two second screws are provided on one end of the inner surface of the end piece inner body, and these are pressed into and engage with two bushings of the second fixing device. A pin-connected lug is provided on the other end of the end piece inner body, and a groove is provided on the inner surface of the end piece outer cover into which the end piece inner body is inserted. The two temples are each pin-connected to the pin-connected lugs of the two end pieces.
[0005] The advantage of the rimless eyeglass structure of the present invention is that by utilizing a structure in which metal is embedded inside plastic, the weight of the entire eyeglasses is light, the strength is high, and they are less likely to deform or break. In addition, the color of the plastic part on the exterior can be varied, which increases the variety of changes to the eyeglasses as a whole. [Brief explanation of the drawings]

The first fixing member 22 and the second fixing member 23 are made of a plastic material, and two bushings 220 and 230 protrude from the first fixing member 22 and the second fixing member 23, respectively. The bushing 220 of the first fixing member 22 is inserted into the first perforations 20 of the lens 2, and the bushing 230 of the second fixing member 23 is inserted into the second perforations 21 of the lens 2. The bridge 3 is provided between the two lenses 2, and is composed of a metal bridge inner body 30 and a plastic bridge outer cover 31. Two first screws 300 are provided at each end of the inner surface of the bridge inner body 30, and two pad fixing members 301 extending rearward and downward are provided facing each other on the inner surface of the bridge inner body 30. Pads 32 are assembled to the pad fixing members 301, and a groove 310 is provided on the inner surface of the bridge outer cover 31 into which the bridge inner body 30 is inserted. Two end pieces 4 are provided facing the outside of the two lenses 2, respectively, and the end piece 4 is composed of one metal end piece inner body 40 and one plastic end piece outer cover 41. Two second screws 400 are provided on one end of the inner surface of the end piece inner body 40, and a pin-connected lug 401 is provided on the other end of the end piece inner body 40, and a groove 410 is provided on the inner surface of the end piece outer cover 41 into which the end piece inner body 40 is inserted. The two temples 5 are respectively assembled to the two end pieces 4, and a pin joint 50 is provided at the front end of each temple 5, and the pin joint 50 of the temple 5 is pin-joined to the pin joint lug 401 of the end piece 4 via a pin joint part 51. In this way, the structure of the rimless eyeglasses is completed.
[0009] 2 to 6 are referred to when assembling the present invention. First, the two bushings 220 of the plastic first fixing member 22 are inserted into the two first holes 20 of the lens 2, respectively, and the two bushings 230 of the second fixing member 23 are inserted into the two second holes 21 of the lens 2, respectively, to fix the first fixing member 22 and the second fixing member 23 to the inner surface of the lens 2. Next, the metal bridge inner body 30 is inserted into the groove 310 of the plastic bridge outer cover 31, and the bridge inner body 30 and the bridge outer cover 31 are combined and integrated, thereby completing the assembly of the bridge 3. The first screws 300 on both ends of the assembled bridge 3 are drilled into the first holes 20 of the two opposing lenses 2, and the first screws 300 are pressed into the bushings 220 of the first fixing member 22. The threaded portions of the first screws 300 engage with the inner walls of the bushings 220, thereby fixing the bridge 3 between the two lenses 2. The metal end-piece inner body 40 is inserted into the groove 410 of the plastic end-piece outer cover 41, and the end-piece inner body 40 and the end-piece outer cover 41 are combined and integrated to complete the assembly of the end-piece 4. The second screw 400 at one end of the assembled end-piece 4 is drilled into the second perforations 21 on the outside of the two opposing lenses 2, and the second screw 400 is pressed into the bushing 230 of the second fixing device 23. The threaded portion of the second screw 400 engages with the inner wall of the bushing 230, thereby fixing the end-piece 4 to the outside of the two lenses 2. The pin joint lug 401 of the end-piece 4 and the pin joint 50 of the temple 5 are then assembled and installed, and pin-joined via the pin joint part 51, thus completing the assembly of the entire rimless eyeglasses. By providing two first perforations 20 and two second perforations 21 on both the inner and outer ends of the lens 2, the present invention increases stability when assembling the bridge 3 and end piece 4 to the lens 2, reducing the risk of loosening, movement, or deformation of the assembled parts.
[0010] The connecting parts of the rimless eyeglasses of the present invention, such as the bridge 3 and endpiece 4, utilize a structure in which metal is embedded in plastic. By combining the lightweight and thin characteristics of the exterior plastic with the strength of the embedded metal, the exterior plastic part is resistant to deformation and breakage even though it is thin. This solves the problem of existing plastic components being prone to deformation and the drawback of metal components being simply heavy. Furthermore, the exterior plastic parts of the present invention can be made in a variety of colors, increasing the variety of changes to the overall eyeglasses.
