## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a pair of eyeglasses and, in particular, to a pair of eyeglasses with the lens thereof firmly fixed to the frame and the temple replaceable with different ones.
2. Description of the Prior Art
In general, a pair of eyeglasses includes a frame, two lenses, and two temples. The frame is usually made of plastic material and integrally formed as one piece including two rims connected with each other. Inner walls of the rims are respectively configured with slots for containing the lenses. However, the frame of the conventional eyeglasses has a serious problem. When the eyeglasses are subjected to an external collision, the lenses thereof are very easy to be separated from the frame and thus damaged. In detail, in order to easily press the lens into the slot of the rim of the frame, the slot can not be over deep. However, in this case, the lens will be easily separated from the frame when subjected to an external collision due to the insufficient depth of the rim's slot.
SUMMARY OF THE INVENTION
In view of the foregoing problem, an objective of the invention is to provide a pair of eyeglasses that includes a frame with rims for fixing the lenses more firmly so that the lenses are not easy to be separated from the frame. Besides, the temple of the eyeglasses of the invention can be replaced with different ones.
A pair of eyeglasses of the invention comprises a frame and two temples. The frame includes two rims whose inner edges are connected with each other. Each of the rims has a space for containing a lens. An inner wall of each of the rims has a slot in which the lens is inserted. An outer edge of each of the rims has a first connecting end and a second connecting end capable of connecting with or being separate from each other. Outer edges of the first and second connecting ends of each of the rims are respectively configured with connecting portions. A front end of each of the temples has a connecting recess for containing the two connecting portions of one of the rims to connect the first and second connecting ends of the rim.
In one embodiment, the two connecting portions of the first and second connecting ends of each of the rims have connecting holes respectively.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 to 4, a pair of eyeglasses 10 of a preferred embodiment of the invention includes a frame 12 and two temples 14 detachably connected with the frame 12. The frame 12 is made of plastic material and integrally formed as one piece including two separate rims 16. In other embodiments, the frame 12 can be made of other material, such as metal or an alloy. The rims 16 are connected together by a bridge portion 18. The rims 16 each have an opening 20 for containing a lens 22. The inner wall of each of the rims 16 has an approximately circular slot 24, into which the edge 26 of the lens 22 can be inserted.
The frame 12 of the embodiment is mainly characterized by the design of the rims 16. In the embodiment, an outer edge of each of the rims 16 includes a first connecting end 28 and a second connecting end 30. The first and second connecting ends 28 and 30 can be connected with or separated from each other. Besides, the first and second connecting ends 28 and 30 have opposite edge surfaces 32 and 34, respectively. When the first connecting end 28 and the second connecting end 30 of each of the rims 16 are separated from each other, a separation space 36 (see FIG. 3) is defined between the edge surfaces 32 and 34 of the first and second connecting ends 28 and 30. When the first and second connecting ends 28 and 30 of each of the rims 16 are connected with each other, the edge surfaces 32 and 34 are connected face to face. Besides, the edge surfaces 32 and 34 are respectively configured with a protrusion 38 and a recess 40 complementary to each other, so that the edge surfaces 32 and 34 can be firmly connected with each other. Besides, outer edges of the first and second connecting ends 28 and 30 of each of the rims 16 are respectively configured with connecting portions 42, each of which is protruded and shaped like a pillar. Each of the connecting portions 42 has a connecting hole 44. When the first and second connecting ends 28 and 30 of each of the rims 16 are connected with each other, the connecting portions 42 thereof are disposed adjacent to each other, and, also, the connecting holes 44 of the connecting portions 42 face each other. Furthermore, in the embodiment, two aligned fixing holes 41 and 43 are respectively disposed in the first and second connecting ends 28 and 30. A fixing element 45, such as a screw, passes through the fixing hole 43 of the second connecting end 30 from the bottom surface of the second connecting end 30, and then is fixed into the fixing hole 41 of the first connecting end 28, so that the first and second connecting ends 28 and 30 of each of the rims 16 can be more firmly connected with each other. Thereby, the frame 12 can be prevented from being broken when subjected to an external collision.
In the embodiment, each of the temples 14 includes a connecting element 46 and a temple element 48. A front end of each of the connecting elements 46 has a connecting recess 50. A width of the connecting recess 50 is almost equivalent to the width of the two adjacent connecting portions 42, so that the connecting recess 50 of the connecting element 46 can accommodate the two connecting portions 42 of the corresponding rim 16, whereby the connecting portions 42 are disposed adjacent to each other. Besides, the front end of each of the connecting elements 46 has a connecting hole 52 connecting with the connecting recess 50. For connecting the connecting recess 50 of each of the connecting elements 46 and the two connecting portions 42 of the rim 16, a fixing element 54, such as a screw, passes through the connecting hole 52 of the connecting element 46 and the connecting holes 44 of the two connecting portions 42. Accordingly, the first and second connecting ends 28 and 30 of the rim 16 are firmly connected with each other, and the connecting element 46 and the rim 16 are pivoted together, so that the temple 14 can be rotated relative to the frame 12 and thus be folded. Besides, a rear end of each of the connecting elements 46 has a through hole 56 and a connecting recess 58, and a front end of each of the temple elements 48 has an elastic sheet 62. The front end 60 of each of the temple elements 48 is inserted into the through hole 56 of the corresponding connecting element 46, so that the elastic sheet 62 can be connected with the connecting recess 58. Besides, the elastic sheet 62 can be separated from the connecting recess 58 by pressing the elastic sheet 62, also separating the temple element 48 from the connecting element 46. Therefore, the temple 14 can be replaced with different ones.
FIGS. 5 and 6 are schematic diagrams of a temple 14 of another embodiment of the invention. A rear end of a temple element 48 of the temple 14 has a through hole 64 for allowing an elastic band or a string (not shown) to pass through. In other embodiments, the connecting element 46 and the temple element 48 can be integrally formed as one piece.
In summary, according to the eyeglasses 10 of the invention, the slot 24 of the rim 16 of the frame 12 can have a sufficient depth for firmly fixing the lens 22, so that the lens 22 will not be separated from the frame 12 when the eyeglasses 10 are subjected to an external collision. In detail, for fitting the lens 22 to the rim 16 of the frame 12, the first connecting end 28 and the second connecting end 30 (see FIG. 3) can be separated from each other first. In this case, even if the circular slot 24 has greater depth, the lens 22 still can be easily fitted to the circular slot 24. Then, when the first and second connecting ends 28 and 30 of the rim 16 are connected with each other, the lens 22 is firmly fixed by the circular slot 24 of the rim 16 (see FIG. 1).
Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
