BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pair of eyeglasses and, more particularly, to an eyeglass structure with a rear-view mirror at a side edge of the pair of eyeglasses.
2. Description of the Related Art
A bicycle is a travel tool of an office worker and a good partner of a cyclist in his/her leisure life. A cyclist who rides a bicycle, albeit small and easily controlled, in fickle traffic conditions on a road might confront lots of risks and has to ride carefully for personal safety. In this regard, a cyclist should obey traffic rules and pay more attentions to personal safety and protection. For a cyclist's personal safety, some warning devices such as bicycle bell, bicycle light and reflector to remind vehicle drivers of a bicycle can be installed on a bicycle in general. Despite the warning devices such as bicycle light and reflector for the basic warning function, some careless vehicle drivers still pay scant attentions to and even accidentally collide with bicycles ahead. Thus, a cyclist should observe traffic conditions at the back early and react to them by decreasing the bicycle's speed or pulling over for personal safety and protection.
BRIEF SUMMARY OF THE INVENTION
Thus, an objective of the present invention is to provide an eyeglass structure with a rear-view mirror through which a cyclist wearing the pair of eyeglasses can observe traffic conditions at the back for better driving safety in cycling.

DETAILED DESCRIPTION OF THE INVENTION
An eyeglass structure according to a first embodiment of the present invention is shown in FIGS. 1 through 4 of the drawings and generally includes a glasses frame 10, a temple 20, and a rear-view mirror unit 30. The glasses frame 10 has two side edges 101 (only one side edge 101 shown in FIGS. 1 through 6), each of which includes at least one locating slot 11. In this embodiment, two locating slots 11 spaced from each other are provided in each side edge 101.
The temple 20 includes a front end 201 pivotally connected to a corresponding side edge 101 of the glasses frame 10. A holding space 21 is formed in an outer side of the front end 201 of the temple 20, and two axial holes 22 aligned to each other in a vertical direction are respectively provided in the front end 201 and in communication with the holding space 21.
The rear-view mirror unit 30 includes a holder 31 and a rear-view mirror 32. In this embodiment, the holder 31 is a frame body and includes a first end 311, a second end 312 spaced from the first end 311 in a horizontal direction perpendicular to the vertical direction, and two horizontal segments 313 connected between the first and second ends 311 and 312. The holder 31 is integrated with the temple 20 when the axial holes 22 of the temple 20 and the first end 311 of the holder 31 are penetrated by a pivot 40, so that The holder 31 is rotatable relative to the temple 20 between a folded position and an unfolded position about an axis defined by the pivot 40. In the folded position, the holder 31 is held in the holding space 21 (FIG. 2). In the unfolded position, the holder 31 is adjacent to the glasses frame 10, and the horizontal segments 313 of the holder 31 are received and positioned in the locating slots 11 of the glasses frame 10 (FIG. 4). The rear-view mirror 32 is pivotally fitted at the second end 312 of the holder 31, so that the rear-view mirror 32 is rotatable relative to the holder 31 and can be held in the holder 31 (FIG. 3) or stopped at a position at which both the rear-view mirror 32 and the holder 31 form an angle (FIG. 4).
As shown in FIG. 2, the rear-view mirror unit 30 which is not in use can be held in the holding space 21 of the temple 20, so that an overall appearance and functions of the pair of eyeglasses of the present invention are identical to those of a pair of conventional glasses. To enable the rear-view mirror 32, a user rotates the holder 31 of the rear-view mirror unit 30 relative to the temple 20 to extract the holder 31 from the holding space 21 (FIG. 3) and stops the holder 31 at a position at which both the holder 31 and the corresponding temple 20 form a right angle approximately for watching traffic conditions at the back through the rear-view mirror 32. Moreover, the holder 31 in FIG. 3 can be rotated forward and parallel with the temple 20 (180 degrees approximately as shown in FIG. 4) for a next rotational movement of the rear-view mirror 32 relative to the holder 31, which coordinates the rear-view mirror 32 to form an right angle approximately relative to the temple 20, so that a user can watch traffic conditions at the back through the rear-view mirror 32. In this embodiment as shown in FIG. 4, any negative effect attributed to shakes of a moving bicycle or vehicle is reduced, and traffic conditions at the back are available to a glasses user because the horizontal segments 313 of the holder 31 are held and positioned in the locating slots 11 of the glasses frame 10.
An eyeglass structure according to a second embodiment of the present invention is shown in FIGS. 5 and 6 and includes a glasses frame 10, a temple 20, and a rear-view mirror unit 30. In this embodiment, the rear-view mirror unit 30 is mounted on the glasses frame 10 compared with the rear-view mirror unit 30 in the first embodiment. Specifically, the glasses frame 10 further includes a joint portion 12 extending inward from each side edge 101, and the front end 201 of the temple 20 is pivotally connected to the joint portion 12. A holding space 21a is formed in an outer side of the joint portion 12 of the glasses frame 10, and the holder 31 is integrated with the glasses frame 10 when a front end of the joint portion 12 and the first end 311 of the holder 31 are penetrated by a pivot 40, so that the holder 31 is rotatable relative to the glasses frame 10 between a folded position and an unfolded position about an axis defined by the pivot 40. In the folded position, the holder 31 is held in the holding space 21a (FIG. 5). In the unfolded position, the holder 31 is adjacent to the glasses frame 10, and the horizontal segments 313 of the holder 31 are received and positioned in the locating slots 11 of the glasses frame 10 (FIG. 6). Thus, a user can watch traffic conditions at the back through the rear-view mirror 32.
The eyeglass structure of the present invention is designed for a cyclist to watch traffic conditions at the back. A cyclist riding a bicycle in the daytime is able to watch a vehicle approaching from behind through the rear-view mirror 32 for a vigilant purpose. Furthermore, a cyclist riding a bicycle at night is able to detect a vehicle's light beam at the back through the rear-view mirror 32 and react to a traffic condition by decreasing the bicycle's speed or pulling over for personal safety and protection.
