Abstract: A spectacle frame combination having an auxiliary lenses frame magnetically and pivotably attached to a primary lenses frame. The primary lenses frame has an integral magnetic portion generating a magnetic field on both the inner and outer surfaces of the temple member. The auxiliary frame may be attached to either the inner or outer surface of the primary frame by the cooperation of magnetic end portions with the complimentary magnetic portion of the primary frame.

Description: TITLE: PIVOTABLE AUXILIARY LENSES FRAME AND PRIMARY LENSES FRAME FOR EYEGLASSES WITH MAGNETIC CLIP-ON MECHANISM BACKGROUND OF THE INVENTION The present invention relates to spectacle or eyeglass frames; and, more particularly, to a combination of a primary frame and an auxiliary frame magnetically attachable to one another. The auxiliary frame may be attached to either the inner surface or outer surface of the primary frame temple member and be pivotable from a first position to a second position. The prior art teaches that magnetic mechanisms may be used to affix or position auxiliary eyeglass frames to a primary eyeglass frame. Various mechanisms are shown in U.S. Pat. Nos. 5,568,207; 5,243,366; 5,181,051; 4,196,981; and 4,070,103. However, none of the prior art teaches or discloses an integral magnetic mechanism for enabling the auxiliary frame to be attached on either the inner or outer surface of the temple member of the primary frame and still allow the auxiliary frame to be pivoted upward away from a parallel alignment of the lenses of both the primary and auxiliary frame. SUMMARY OF THE INVENTION A spectacle frame combination including an auxiliary lenses frame magnetically and pivotably attachable to a primary lenses frame. The rearwardly extending temple members of the primary frame each incorporate an integral magnetic section which generates a magnetic field along both the outer and inner surfaces of a front section of the temple member forward the temple hinge. The auxiliary frame has rearwardly extending engagement arms which each incorporate an integral magnetic portion for rotatabie attachment to complimentary sections of the integral magnetic portion of the front section of the temple members.

PREFERRED EMBODIMENT Fig. 1A illustrates a front elevation view of the primary lenses frame of the present invention. Primary frame 10 has the conventional eyepiece rims 12a and 12b and lenses 20a and 20b. These may be any shape desired by the designer or wearer. The rims are joined by bridge 14 and are provided with nose pieces 16a and 16b. Also seen in Fig. 1A are the face sections 18a and 18b of the hinged temple members of the frame. A side elevation view of the frame 10 is shown in Fig. IB. Lens member 20b is affixed in rim 12b. The side temple member 22b is L-shaped and extends generally rearwardly from the front of the frame 10. A hinge 24b connects a front section 26b and rear section 28b of the temple member 22b. An ear section 30b completes the distal section of the temple member. Attention is directed to the front section 26b forward of hinge 24b. An integral primary magnetic portion 32b is formed along the front section 26b of the temple member 22b. Magnetic portion 32b generates a magnetic field F m along both the inner 33b and outer surfaces 34b of the front section 26b. Fig. 1C is a top plan view which illustrates that primary magnetic portions 32a and 32b of the temples generate a magnetic field F m on the inner surfaces 35a and 33b and the outer surfaces 37a and 34b of the front sections 32a and 32b. Turning to Figs. 2A and 2B, one embodiment of the auxiliary lenses frame 40 of the present invention is shown. Again, a bridge 42 connects the eyepiece rims 44a and 44b. The rims are designed to retain and support auxiliary lenses 46a and 46b. Extending outwardly and rearwardly are L-shaped, engagement arms 48a and 48b. At the distal end of each arm is an integral auxiliary magnetic portion 50a and 50b which cooperates with complimentary primary magnetic portions 32a and 32b of the primary frame 10 to rotatably secure and retain the auxiliary frame 40 to the primary frame 10. The combination of the present invention is shown in Figs. 3A-3D. In Fig. 3 A a front elevation view shows the auxiliary frame 40 attached to the primary frame 10. Engagement arms 48a and 48b extend over and around face sections 18a and 18b and engage integral auxiliary magnetic portion 50a and 50b with outer surfaces 34b and 37a of integral magnetic portions 32b and 32a, respectively. Fig. 3B shows a side elevation view of the combination with engagement arm 48b extending along outside surface 34b of frame 10. Auxiliary magnetic portion 50b is magnetically coupled to primary magnetic portion 32b as a result of the cooperation of the complimentary magnetic portions. Fig. 3C is a top plan view illustrating the engagement of the auxiliary magnetic portions 50b and 50a with the outside surface 34b and 37a, respectively, of the front sections 26b and 26a. Fig. 3D illustrates that the auxiliary lenses frame 40 (shown in broken lines for clarity) may be rotated about the magnetic attachment. Because the magnetic fields F m extend outwardly from the surfaces of the parts, there is no need for the precise fit necessary in prior art devices. Fig. 3D shows that magnetic portion 50b has engaged primary magnetic portion 32b at a forward edge of the portion 32b. Thus, the auxiliary spectacle lenses frame 40 may be rotated from a first down position in which the primary lenses 20a and 20b and the auxiliary lenses 46a and 46b are generally in parallel alignment to a second position where the auxiliary lenses 46a and 46b are generally moved upwardly and out of the line of sight; a position more generally perpendicular to the primary lenses. As will be described below, this rotational aspect may be achieved even when the auxiliary lenses frame 40 is affixed on the inside surface 35a or 33 b of the front section of the temple member. Figs. 4A-4C show a second embodiment of the auxiliary lenses frame 60 with bridge 62; rims 64a and 64b; engagement arms 68a and 68b; and auxiliary magnetic portions 70a and 70b. Fig. 4C specifically shows how the auxiliary frame 60 engages with primary frame 10 in a top plan view. The auxiliary magnetic portions 70a and 70b rotatably attach to the inner surfaces 33b and 35a of the frame 10. Engagement arms 68a and 68b extend over the top of face sections 18a and 18b of frame 10. Auxiliary frame 60 may be rotated upwardly as previously discussed in the embodiment shown in Figs. 3A-3D. Although the invention has been described with reference to a specific embodiment, this description is not meant to be construed in a limiting sense. On the contrary, various modifications of the disclosed embodiments will become apparent to those skilled in the art upon reference to the description of the invention. It is therefore contemplated that the appended claims will cover such modifications, alternatives, and equivalents that fall within the true spirit and scope of the invention.
