DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 to 5, a pair of eyeglasses of the present invention is comprised of a lens 1 and a frame 2, wherein the lens 1 is made in one-piece and has a positioning portion 11 at the middle portion thereof. The positioning portion 11 can be a recess or a hole.
The frame 2 is included a holder 20 and two temples 30 which are connected to both ends of the holder 20. The holder 20 has two rims 21 and a connection portion 22 is connected between the two rims 21. The connection portion 22 of the holder 20 has a clip slot 221 opened downwardly. The width of the clip slot 221 is adapted to the width of the lens 1. A through hole 222 is defined in the holder 20 and communicates with the clip slot 221. The connection portion 22 of the holder 20 has a recessed area 223 defined in the inside thereof which communicates with the through hole 222. Two threaded holes 224 are defined in the recessed area 223. Each of the two rims 21 has an engaging slot 225 defined in the inside of the outer end thereof. A bead 23 and a spring 24 are accommodated in the through hole 222. A restriction member 25 is connected to the holder 20 and blocks the through hole 222 inside of the holder 20. The restriction member 25 can be a bridge. The restriction member 25 is removably installed at the inner side of the connection portion 22 and has two apertures 250 corresponding to the two threaded holes 224 of the recessed area 223. Two screws 251 are fastened into the apertures 250 to connect to the threaded holes 224 as so to fix the restriction member 25 to the inside of the connection member 22. The spring 24 is installed between the bead 23 and the restriction member 25. The bead 23 partially protrudes from the through hole 222. The width of the clip slot 2221 is smaller than the diameter of the bead 23 to prevent the bead 23 dropping from the clip slot 221. The two temples 30 are respectively and pivotably connected to the two outer ends of the two rims 21.
Each of the two rims 21 has a fixing member 26 located therein so as to secure the lens 1. Each of the rims 26 has a lug 260 and a protrusion 261 extending on two sides thereof. The lug 260 is engaged with the recessed area 223 of the connection portion 22 of the holder 20. The lug 260 has a hole 262 corresponding to the threaded hole 224 of the recessed area 223 of the connection portion 22 and the aperture 250 of the restriction member 25. By the screws 251, the restriction member 25 and the fixing members 26 are fixed to the holder 20. The protrusion 261 of the fixing member 26 is inserted into the engaging slot 225 of the rim 21.
When installing the lens 1 to the frame 2, as shown in FIGS. 5 and 6, the middle portion of the lens 1 is engaged with the clip slot 221 of the holder 20 to align the positioning portion 11 of the lens 1 with the through hole 222. The bead 23 is pushed into the positioning portion 11 by the resilience of the spring 24 so that the lens 1 is able to be fixed into the holder 20 without extra forces. When removing the lens 1, the bead 23 is sphere and the positioning portion 11 of the lens 1 is curved, so, when the lens 1 is simply pulled downward, the surface of the lens 1 pushes against the bead 23 to be retracted into the through hole 222 and to compress the spring 24, so that the bead 23 is removed from the positioning portion 11 of the lens 1 and the lens 1 is removed from the holder 20.
The lens 1 is easily engaged with the clip slot 221 of the holder 20, and the spring 24 pushes the bead 23 partially into the positioning portion 11 of the lense 1 so as to be lens 1 is firmly secured into the holder 20, The fixing structure for lens 1 is simple and lens is easily and quickly installed or removed from the holder 20. Hence, the manufacturing cost is also low.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
