Eyeglass combination having auxiliary frame

Abstract: An eyeglass combination includes a primary frame (10) having a bridge (11) and two side studs (12). An auxiliary frame (20) includes a bridge (21) and two side extensions (22) each having a rear flange (23) for engaging with the stud (12) and for allowing the auxiliary frame (20) to be secured to typical primary frame (10). The rear flanges (23) each includes a magnet (26) for engaging with another magnet (14) engaged in the studs (12) or for engaging with the studs of magnetic material. The magnets are preferably disposed laterally.

Description: BACKGROUND OF THE INVENTION 1. Field of the invention The present invention relates to a pair of eyeglasses, and more particularly to a pair of eyeglasses having an auxiliary frame for supporting auxiliary lenses. 2. Description of the Prior Art The closest prior art of which applicant is aware is US Patent 5,568,207 to Chao and has been assigned to the present assignee. The primary frame are required to be engaged with magnets for actuating with the magnets engaged in the auxiliary frame, such that the auxiliary frame may not be attached to typical spectacle frame having no magnets therein. Documents DE 8806898, JP 07128620, US 5737054, EP 0848276, JP 3031881, disclose as well auxiliary frame using magnets on the primary frame. The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional auxiliary spectacle frames. SUMMARY OF THE INVENTION The primary objective of the present invention is to provide an auxiliary frame for attaching typical spectacle frame having no magnets therein. The other objective of the present invention is to provide a primary frame and an auxiliary frame having magnets disposed laterally. In accordance with the invention, an eyeglass combination is provided, described by the features of claim 1. Additional features of the eyeglass combination are defined in dependent claims. Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded view of an eyeglass combination having an auxiliary frame in accordance with the present invention ; FIG. 2 is a perspective view of the eyeglass combination; and FIG. 3 is a cross sectional view taken along lines 3-3 of FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, and initially to FIGS. 1 and 2, an eyeglass combination in accordance with the present invention comprises a primary frame 10 for supporting primary lenses 90 and including a bridge 11 formed in the middle and including two studs 12 formed in the side portions. The bridge 11 and the studs 12 each includes a magnet 14 disposed laterally having a pole (such as S as shown in FIG. 3) arranged in front of the other (N in FIG. 3). An auxiliary frame 20 for supporting auxiliary lenses 91 and for disposing in front of the primary frame includes a bridge 21 and two extensions 22 disposed in the side portions and extended rearward for engaging over the bridge 11 and the studs 12 of the primary frame 10 respectively. The bridge 21 includes an arm 24 extended rearward. The extensions 22 and the arm 24 each includes a rear end having a flange 23, 25 dependent downward. The flanges 23, 25 each includes a magnet 26 disposed laterally having a pole (S in FIG. 3) arranged in front of the other (N in FIG. 3) for allowing the S pole to engage with the N pole of the magnet 14 of the primary frame 10. It is to be noted that the flanges 23, 25 of the extensions 22 and of the arm 24 are extended downward for engaging with the studs 12 and the bridge 11 such that the flanges 23, 25 themselves form a hook means for securing the auxiliary frame 20 to the primary frame 10. In addition, the magnets 14, 26 are disposed laterally at the rear side of the bridge and/or the studs and at the front side of each flange, such that the flanges 23, 25 may further be stably and solidly attracted and retained in place. It is further to be noted that the flanges 23, 25 may also be used to hook to the typical eyeglasses having no magnets engaged therein, such that the auxiliary frame 20 may be attached to any of the typical eyeglasses. Particularly, when the typical eyeglasses are made of metal or other magnetic materials, the magnets 26 of the auxiliary frame 20 may also be used for attracting the typical eyeglasses and may also be used for solidly securing the auxiliary frame to the typical eyeglasses. It is also to be noted that with only the arm 24 and the magnet 26 therein, the auxiliary frame 20 may also be solidly secured to the primary frame 10. Without the arm 24 and without the magnets 26, the auxiliary frame 20 may also be secured to the primary frame 10 by engaging the flanges 23 with the studs 12. The provision of the magnets 26 and 14 may further solidly secure the auxiliary frame 20 to the primary frame 10. Accordingly, the eyeglass combination in accordance with the present invention includes an auxiliary frame having a pair of extensions and/or an arm for engaging with the studs and/or the bridge of the primary frame, for allowing the auxiliary frame to be secured to various kinds of eyeglasses having no magnets therein. In addition, the provision of the flanges 23, 25 may also be used for solidly securing the auxiliary frame to the primary frame 10. Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the scope of the appended claims.
