TITLE: EYEGLASS ASSEMBLY HAVING AUXILIARY FRAME
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 extensions of the primary frame are not provided in the rim lock portions.
The present invention has arisen to provide a primary frame having the magnets provided in the rim lock portions.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an eyeglass assembly in which the extensions of the primary frame may be provided in the rim lock portions and may be engaged with magnets for allowing the lenses to be easily inserted into the primary frame.
In accordance with one aspect of the invention, there is provided an eyeglass assembly comprising a primary frame including two sides each having a rim lock, each of the rim locks including an upper member and a lower member, each of the lower members including an opening, two first magnets, each including an upper portion secured within the upper member and each including a lower portion receivable with clearance in the opening of the lower member for allowing the lower portion to be disengaged from the lower member, an auxiliary frame for disposing in front of the primary frame, the auxiliary frame including two sides, each having an extension extended rearward for overlying a corresponding rim lock, and two second magnets secured in the extensions for engaging with the first magnets and for securing the auxiliary frame to the primary frame.
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 assembly having an auxiliary frame in accordance with the present invention;
FIG. 2 is a perspective view of the eyeglass assembly; 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 assembly in accordance with the present invention comprises a primary frame 10 for supporting primary lenses 90, which frame includes two rim locks 11 formed in the side portions. Two magnets 19 are secured within the rim locks 11 respectively. An auxiliary frame 20 for supporting auxiliary lenses 91 and for disposing in front of the primary frame includes two extensions 21 disposed at the side portions and extended rearward for overlying the respective rim locks 11 of the primary frame 10. Each of the extensions 21 mounts a magnet 22 for engaging with the magnet 19 of the adjacent rim lock 11 and for securing the auxiliary frame 20 to the primary frame 10.
Referring again to FIG. l, each of the rim locks 11 includes an upper member 12 and a lower member 14 for allowing the primary frame to be opened and for allowing lenses to be easily inserted into the primary frame. The upper and lower members 12, 14 include holes 15 engageable by fasteners 16 for securing the upper and lower members 12, 14 together, and include an orifice 17 for engagement by another fastener 18 which may be used for securing the legs 92 to the primary frame 10.
Referring next to FIG. 3, the magnet 19 includes an upper portion secured within the upper member 12 and a lower portion receivable with clearance in an opening 141 formed in the lower member 14. The opening 141 is of a diameter greater than that of the lower portion of the magnet 19 such that the lower portion of the magnet 19 may be disengaged from the lower member 14 when the upper member 12 is disengaged from the lower member 14 for inserting lenses into the primary frame 10. The magnets 19 thus will not affect the engagement of the lenses into the primary frame.
Alternatively, each of the upper and lower members 12, 14 includes an inner thread formed therein, and the magnets 19 are bolts for engaging with the inner threads of the upper and lower members 12, 14 and for securing the members 12, 14 together without the fasteners 16.
Accordingly, in one embodiment the eyeglass assembly in accordance with the present invention includes a primary frame having a pair of magnets secured in the rim locks and having a configuration for preventing the magnets from affecting the assembling of the lenses.
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 spirit and scope of the invention as hereinafter claimed.
a primary frame including two sides each having a rim lock, each of said rim locks including an upper member and a lower member, each of said lower members including an opening;
two first magnets, each including an upper portion mounted withing said upper member and each including a lower portion receivable, with clearance, in said opening of said lower member for allowing said lower portion to be disengaged from said lower member;
an auxiliary frame for disposing in front of said primary frame, said auxiliary frame including two sides each having an extension extended rearward for overlying a corresponding rim lock; and two second magnets mounted in said extensions for engaging with said first magnets and for securing said auxiliary frame to said primary frame.
a primary frame including two sides each having a rim lock, each of said rim locks including an upper member and a lower member, each of said upper and lower members including a threaded hole extending therethrough;
two first threaded magnetic fasteners, each extending through the holes of corresponding upper and lower rim lock members to hold said members together;
an auxiliary frame for disposing in front of said primary frame, said auxiliary frame including two sides each having an extension extended rearward for overlying a corresponding rim lock; and two second magnets mounted in said extensions for engaging with said first magnetic fasteners and for securing said auxiliary frame to said primary frame.
