ABSTRACT:
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 U.S. Pat. No. 5,568,207 to Chao and has been assigned to the present assignee. The primary frame should be engaged with magnets for actuating with the magnets engaged in the auxiliary frame, such that the auxiliary frame may not be attached to the spectacle frame having no magnets therein.
The present invention has arisen to provide a novel configuration for securing the auxiliary frame to the primary frame.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an eyeglass device in which the side studs of the primary frame each includes an opening for engaging with a hook or a magnet of the auxiliary frame for solidly and stably securing the auxiliary frame to the primary frame.
In accordance with one aspect of the invention, there is provided an eyeglass device comprising a primary frame including two sides each having a stud, the studs each including an opening, and an auxiliary frame for disposing in front of the primary frame, the auxiliary frame including two sides each having a hook member for extending over the stud and for engaging with the opening and for securing the auxiliary frame to the primary frame.
The openings each includes a bottom portion, the studs each includes a first magnet secured in the bottom portion of the opening, the hook members are made of magnetic material for engaging with the first magnets and for securing the auxiliary frame to the primary frame.
The hook members each includes an extension extended rearward from the side of the auxiliary frame and extended toward the primary frame and each includes a magnetic member extended downward for engaging with the opening of the stud and for engaging with the first magnets and for securing the auxiliary frame to the primary frame. The magnetic members are magnets.
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.
