Auxiliary lenses for eyeglasses

Abstract: An eyeglass device includes a spectacle frame (10) having two legs (11) pivotally coupled to two side extensions (21) and having two magnetic members (14) secured in the rear and side portions. The auxiliary frame (20) (10) includes two legs (11) engaged on the spectacle frame (10) and each having a magnetic member (22) for engaging with the magnetic members (14) of the spectacle frame (10) so as to secure the spectacle frames (10, 20) together and so as to prevent the auxiliary frame (20) from moving downward relative to the spectacle frame (10).

Description: The invention relates to auxiliary lenses for attaching to the eyeglasses. Typical spectacle frames known for example by JP-A-07 128 620 include a magnetic material secured to the peripheral portion or the side portion for attaching an auxiliary frame to the spectacle frame. The auxiliary frame includes a magnetic strip for engaging with the magnetic material of the spectacle frame. However, the auxiliary frame may be easily disengaged from the frames when the users are jumping. In addition, the magnetic materials are embedded in the frames such that the frames should be excavated with cavities for engaging with the magnetic members and such that the frames are weakened. The invention is to provide an auxiliary frame which may be stably engaged on the frames. As claimed, an eyeglasses device comprises a spectacle frame and an auxiliary frame for supporting lenses, the spectacle frame including two first magnetic members and two side portions, each of said side portions having an extension for pivotally coupling a leg, the auxiliary frame including two arms each securing a respective second magnetic member for engaging with a respective one of said first magnetic members According to the invention, the spectacle frame includes two projections each secured to the rear part of a respective one of said two side portions and each securing a respective one of said first magnetic members, each arm of the auxiliary frame engages over the upper part of a respective one of said two side portions each arm being supported on the upper part of a respective one of said two side portions to prevent the auxiliary frame from moving downward relative to the spectacle frame. FIGS. 1 and 2 are front views of a spectacle frame and of an auxiliary frame respectively; FIGS. 3 and 4 are top views of the spectacle frame and the auxiliary frame respectively; FIG. 5 is a front view of the frame combination; FIG. 6 is a top view of the frame combination; and FIG. 7 is a cross sectional view taken along lines 7-7 of FIG. 6. In FIGS. 1 to 4, an eyeglass device comprises a spectacle frame 10 and an auxiliary frame 20 for supporting lenses. The spectacle frame 10 includes two extensions 11 extended from the side portions for pivotally coupling two legs 12. The spectacle frame 10 includes two projections 13 secured to the side portions for supporting magnetic members 14. The auxiliary frame 20 includes two side portions each having an arm 21 engaged with the upper portion of the spectacle frame 10 (FIGS. 5 and 6). The auxiliary frame 20 includes two magnetic members 22 secured to the arms 21 for engaging with the magnetic members 14 such that the auxiliary frame 20 may be stably supported on the spectacle frame 10, best shown in FIGS. 5 and 6. The arms 21 are engaged on the spectacle frame 10 for stably supporting the auxiliary frame 20 on the spectacle frame 10. The auxiliary frame 20 will not move downward relative to the spectacle frame and will not be easily disengaged from the spectacle frame when the users are jumping. The magnetic members 14, 22 are not embedded in the frames 10, 20 such that the strength of the frames 10, 20 will not be decreased. In FIG. 7, the projections 13 and the magnetic members 14 are located lower than the upper portion of the spectacle frame 10; and the end portions of the arms 21 and/or the magnetic members 22 extend downward toward the projections 13 such that the arms 21 and the magnetic members 22 may hook on the spectacle frame 10 and such that the auxiliary frame 20 may further be stably supported and secured to the spectacle frame 10.

Claims: An eyeglasses device comprising a spectacle frame (10) and an auxiliary frame (20) for supporting lenses, the spectacle frame (10) including two first magnetic members (14) and two side portions, each of said side portions having an extension (11) for pivotally coupling a leg (12), the auxiliary frame (20) including two arms (21) each securing a respective second magnetic member (22) for engaging with a respective one of said first magnetic members characterized that the spectacle frame (10) includes two projections (13) each secured to the rear part of a respective one of said two side portions and each securing a respective one of said first magnetic members (14), each arm (21) of the auxiliary frame (20) engages over the upper part of a respective one of said two side portions, each arm (21) being supported on the upper part of a respective one of said two side portions to prevent the auxiliary frame (20) from moving downward relative to the spectacle frame (10). An eyeglasses device according to claim 1, wherein the projections (13) and the first magnetic members (14) are secured to the lower part of the side portions of the spectacles frame (10), the second magnetic members (22) are extended downward for hooking on the spectacle frame (10) so as to further secure the auxiliary frame (20) to the spectacle frame (10).
