DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] Please refer to FIG. 1 and FIG. 2, which show the structure of an interchangeable frame for eyeglasses according to an embodiment of the present invention. The interchangeable frame for eyeglasses comprises an upper frame 1 and a lower frame 2.

[0015] The upper frame 1 comprises a middle section 11. Two upper lens-assembling portions 12 are formed at the both sides of the middle section 11 and opened at the lower portion of each upper lens-assembling portion 12, and a joining portion 13 is concavely formed at the front bottom of the middle section 11. A connection block 131 is connected with the bottom of the joining portion 13, and each of the both sides of the connection block 131 is formed with a ditch 132. Moreover, an inverted V-shaped fastener 14 is set on the joining portion 13, and two nose stands 15 are set between the fastener 14 and the connection block 131 of the joining portion 13. In addition, the middle section 11 is formed with two third locking holes 111, which are corresponded to the back of the connection block 131 of the joining portion 13, and the back of the fastener 14 is formed with two first locking holes 141, which are corresponded to the two third locking holes 111 of the middle section 11, meanwhile, a second locking hole 151 is formed in the upper end of each nose stand 15, corresponding to the third locking hole 111 of the middle section 11 and the first locking hole 141 of the fastener 14. Furthermore, two latches are respectively through the third locking holes 111 in the middle section 11 and the second locking holes 151 in the nose stands 15, and then screwed into the first locking holes 141 in the fastener 14 for fastening the nose stands 15 and the fastener 14 onto the middle section 11. The front end of each of the nose stands 15 is concavely formed with a gap 152 for receiving each of the both sides of the inverted V-shaped fastener 14.

[0016] An inverted V-shaped assembling part 21 is formed at the middle of the lower frame 2 and connected with the joining portion 13 of the upper frame 1. A connection notch 211 is concavely formed at the upper end of the assembling part 21 to connect with the connection block 131 at the bottom of the joining portion 13. Two flanges 212 are respectively formed at the both sides of the connection notch 211 to engage in the ditches 132 at the both sides of the connection block 131. In addition, two lower lens-assembling portions 22 are formed at the both sides of the assembling part 21 of the lower frame 2 and opened at the upper portion of each lower lens-assembling portion 22 to pair with the two upper lens-assembling portions 12 of the upper frame 1 for forming a complete lens-assembling part.

[0017] Accordingly, when the interchangeable frame for eyeglasses of the present invention is assembled, two temples are respectively assembled to the both sides of the upper frame 1, and two lenses 3 are respectively assembled to the upper lens-assembling portions 12 of the upper frame 1, at this time, the bottom edge of the lenses 3 is exposed from the bottom of the upper lens-assembling portions 12 of the upper frame 1, forming a semi-rim eyeglasses. Then, the two nose stands 15 are corresponded to the both sides of the inverted V-shaped fastener 14 and against the side of the lenses 3 to locate. When the user does outdoor activities or construction, the design of the weight of the semi-rim eyeglasses is lithe for reducing the weight of the eyeglasses that presses on the user's nose and ear, improving the wear comfort. With the cool and neat appearance of the semi-rim eyeglasses, the user's fashionable and trendy appearance is improved.

[0018] Moreover, when the safety and stability of the lens assembly are improved, please refer to FIG. 3 and FIG. 4, the lower frame 2 is assembled to the upper frame 1. When the lower frame 2 is assembled, the connection notch 211 of the upper end of the assembling part 21 of the lower frame 2 is connected to the connection block 131 at the bottom of the joining portion 13 of the upper frame 1, and the flanges 212 formed at the both sides of the connection notch 211 are engaged to the ditchs 132 at the both sides of the connection block 131, shown as FIG. 5. At this time, the exposed part of the two lenses 3, which is exposed from the bottom of the upper lens-assembling portions 12 of the upper frame 1, is corresponded to assemble to the two lower lens-assembling portions 22 of the lower frame 2 for forming the full-rim eyeglasses. Accordingly, the lenses 3 are hold by the upper and lower lens-assembling portions 12, 22 of the upper frame 1 and the lower frame 2 to improve the safety and the stability of the lens assembly. It indeed prevents the unexpected dropping situation, and the full-rim eyeglasses improve the user's steady when it is used for dressing up.

[0019] Therefore, due to the structure design of the interchangeable frame for eyeglasses of the present invention, according to the required, it can be assembled and disassembled freely to form the semi-rim eyeglasses or the full-rim eyeglasses. Furthermore, the upper frame 1 and the lower frame 2 can be different color and pattern for improving the fashion and trendy of its appearance. For the users who like novel and changeable things, they do not need to buy different type of eyeglasses, such as semi-rim eyeglasses and full-rim eyeglasses, also not need to assemble the lenses to the every semi-rim eyeglasses and full-rim eyeglasses, greatly saving the cost of buying glasses. For the eyeglasses industry, when the eyeglasses are displayed for sale, it does not need to display the all kinds of the semi-rim eyeglasses and the full-rim eyeglasses for consumers choosing, lightening the operating cost.

[0020] However, the foregoing embodiments and drawings does not limits the interchangeable frame for eyeglasses of the present invention, it will be obvious to those skilled in the art that various modifications may be made without departing from the spirit and the scope of the present invention.
