Systems and methods for retention of lenses in eyeglass frames using elastic cushion connectors
View Patent ↗User configurable eyeglasses employing retention of lenses in eyeglass frames using elastic cushion connectors may include a pair of lenses, each lens comprising at least one tab extending from the lens. An eyeglasses frame may define at least two fittings, each fitting positioned to receive one tab extending from a lens and each fitting sized larger than the tab to be received. A plurality of eyeglass lens retention cushions are each adapted to be disposed in one of the fittings and to receive one of the tabs. Each eyeglass lens retention cushion might have an elastic cushion body having a relaxed, or in situ, exterior size larger than an interior socket of the fittings and may have an interior opening with a relaxed, or in situ, size smaller than a tab extending from an eyeglasses lens.
1. An eyeglass lens retention cushion comprising an elastic cushion body having a relaxed exterior size larger than an interior socket of a fitting defined by an eyeglasses frame and defining an interior opening having a relaxed size smaller than a tab extending from an eyeglasses lens corresponding to a position of the fitting.
2. The eyeglass lens retention cushion of claim 1 , wherein the eyeglass lens comprises a pair of generally opposing tabs extending from the eyeglass lens.
3. The eyeglass lens retention cushion of claim 1 , wherein the eyeglasses frame defines a pair of generally opposing fitting pairs, each fitting positioned to receive one tab extending from the eyeglass lens.
4. User configurable eyeglasses comprising:
a pair of lenses, each lens comprising at least one tab extending from the lens;
an eyeglasses frame defining at least two fittings, each fitting positioned to receive one tab extending from a corresponding lens, each fitting sized larger than the tab to be received; and
a plurality of elastic cushion connectors, each elastic cushion connector of the plurality of cushion connectors having a relaxed exterior size larger than an interior socket of one of the at least two fittings and an interior opening having a relaxed size smaller than one of the at least one tab extending from one of the pair of lenses, each elastic cushion connector of the plurality of cushion connectors being adapted to be disposed in one of the at least two fittings and to receive one of the at least one tab extending from one of the pair of lenses.
5. The user configurable eyeglasses of claim 4 , wherein each lens comprises a pair of generally opposing tabs extending from the lens, and the eyeglasses frame defines a pair of generally opposing fitting pairs, each fitting positioned to receive one tab extending from the corresponding lens.
6. The user configurable eyeglasses of claim 5 , wherein each lens snap-fits into the eyeglasses frame with the plurality of elastic cushion connectors tensioning each lens in the eyeglasses frame between one fitting pair.
7. The user configurable eyeglasses of claim 4 , wherein the plurality of elastic cushion connectors are formed from a silicone polymer.
8. The user configurable eyeglasses of claim 4 , wherein each elastic cushion connector of plurality of cushion connectors is defined in one fitting to receive one of the at least one tab extending from one of the pair of lenses.
9. A method comprising:
disposing at least one tab at an edge of an eyeglass lens, extending from the eyeglass lens;
defining a plurality of fittings in an eyeglasses frame, one of the plurality of fittings positioned to correspond to one tab extending from the eyeglass lens, each fitting defining an interior socket larger than a corresponding tab; and
disposing an elastic cushion connector between each fitting of the plurality of fittings and the corresponding tab, in a fitting socket of the respective fitting and at least partially around the corresponding tab, flexibly securing the eyeglass lens into the eyeglasses frame, wherein the elastic cushion connector has a relaxed exterior size larger than an interior socket of one of at least two fittings and an interior opening having a relaxed size smaller than one of the at least one tab extending from the eyeglass lens.
10. The method of claim 9 , wherein disposing the at least one tab at the edge of the eyeglass lens comprises attaching the at least one tab to the eyeglass lens.
11. The method of claim 9 , wherein disposing the at least one tab at the edge of the eyeglass lens comprises defining the at least one tab by forming or shaping the at least one tab from the eyeglass lens to extend from the eyeglass lens.
12. The method of claim 9 , wherein disposing the elastic cushion connector between each fitting of the at least two fittings and the corresponding tab comprises:
placing the elastic cushion connector at least partially around the corresponding tab; and
snap-fitting elastic cushion connector and tab into the fitting socket of the respective fitting.
13. The method of claim 9 , wherein disposing the elastic cushion connector between each fitting of the at least two fittings and the corresponding tab comprises:
inserting the elastic cushion connector into the fitting socket of the respective fitting;
inserting the corresponding tab into the interior opening of the elastic cushion connector; and
snap-fitting the eyeglass lens into the eyeglasses frame.
14. A method comprising:
disposing an elastic cushion connector having a relaxed outer size larger than an interior socket of a fitting defined in an eyeglasses frame and a relaxed inner opening smaller than a tab extending from an edge of an eyeglass lens into the interior socket of the fitting and around a corresponding tab extending from the edge of the eyeglass lens, between the corresponding tab and the fitting; and
flexibly securing the eyeglass lens into the eyeglasses frame.
15. The method of claim 14 , wherein disposing the elastic cushion connector between the corresponding tab and the fitting comprises:
placing the elastic cushion connector at least partially around the corresponding tab; and
snap-fitting the elastic cushion connector and the corresponding tab into the socket of the fitting.
16. The method of claim 14 , wherein disposing the elastic cushion connector between the corresponding tab and the fitting comprises:
placing the elastic cushion connector at least partially around the corresponding tab; and
snap-fitting the elastic cushion connector and the corresponding tab into the socket of the eyeglasses frame.
17. The method of claim 14 , further comprising disposing the corresponding tab extending from the edge of the eyeglass lens, wherein disposing the corresponding tab comprises attaching corresponding tab to the eyeglass lens.
18. The method of claim 14 , further comprising:
forming the corresponding tab from the eyeglass lens to extend from the eyeglass lens; and
disposing the corresponding tab extending from the edge of the eyeglass lens.
