Eyeglass device
Eyeglasses comprise a pair of spectacles having primary lenses and an auxiliary lens assembly attached to the spectacles. The auxiliary lens assembly is secured by a subframe that includes at least one arm having a magnet at one end to co-operate with a magnet provided on the spectacles. A hinge is provided on the subframe at the opposite end of the arm to allow the auxiliary lens assembly to move from a position in which the primary lenses are covered to a position in which they are exposed.
1. An auxiliary lens assembly for use with a pair of spectacles having a pair of primary lenses interconnected by a first bridge, said assembly comprising an auxiliary frame having a pair of auxiliary lenses interconnected to one another by a second bridge; and a subframe for detachably interconnecting said first bridge to said second bridge, said subframe connected to said second bridge at one end and adapted for releasable connection to said first bridge at an other end, said subframe adapted to permit movement of said assembly between a first position in which said auxiliary lenses cover said primary lenses to a second position in which they do not cover said primary lenses and to retain said assembly in either of said positions.
2. The assembly of claim 1 wherein said releasable connection to said first bridge is provided by a magnetic connection thereto.
3. The assembly of claim 2 wherein said magnetic connection comprises a magnetic member of said other end interacting with a magnetically attractive socket on said first bridge.
4. The assembly of claim 3 wherein said socket comprises a magnetic member inserted therein.
5. The assembly of claim 2 wherein said magnetic connection is provided by a magnetic member of said other end engaging said first bridge, said first bridge being made of a magnetic material.
6. The assembly of claim 1 wherein said releasable connection to said first bridge is provided by a mechanical connection thereto.
7. The assembly of claim 6 wherein said mechanical connection is provided by said other end interacting with a socket on said spectacles.
8. The assembly of claim 7 wherein said other end comprises a pair of tangs with outwardly directed feet, said feet operable to detachably fit said tangs in said socket to provide said mechanical connection.
9. The assembly of claim 1 wherein said subframe comprises a first leg and a second leg interconnected by a hinge intermediate said one end and said other end, said hinge adapted to permit said movement of said assembly between said first and second positions and retain said assembly in either of said positions.
10. The assembly of claim 9 wherein said hinge comprises a friction pin to provide frictional resistance that enables said hinge to retain said assembly in said positions.
11. The assembly of claim 1 wherein said subframe comprises a first arm having a first rotatable connection to said second bridge at said one end, said first rotatable connection being operable to permit said movement of said assembly between said first and second positions and to retain said assembly in either of said positions.
12. The assembly of claim 11 wherein said first rotatable connection interacts with the cross-sectional shape of said bridge to retain said assembly in said positions.
13. The assembly of claim 11 wherein said subframe further comprises a second arm being parallel with said first arm, said second arm having a second rotatable connection to said bridge at one end thereof, and adapted for releasable connection to said spectacles at another end thereof.
14. The assembly of claim 13 wherein said first and second arms are interconnected by a third bridge to provide further stability to said subframe.
