Abstract

The present description provides an eyewear lens attachment assembly that provides easy and secure attachment between a lens in a frame. An exemplary eyewear lens attachment assembly described herein includes a lens having a lens opening proximate a nose region, a frame holder having a frame engagement feature and a retainer engagement feature, and a slidable retainer including an outer surface, an inner surface, and a flanged projection extending outwardly from the inner surface. When the flanged projection is positioned through the lens opening, the retainer is slidable between an engaged position in which the retainer is secured to the frame holder and a disengaged position in which the retainer and frame holder may be separated.

First claim

What is claimed is:

1. An eyewear lens attachment assembly, comprising:
a lens having a lens opening proximate a nose region;
a frame holder having a frame engagement feature and a retainer engagement feature; and
a slidable retainer including an outer surface, an inner surface, and a flanged projection extending outwardly from the inner surface, the flanged projection positionable through the lens opening;
wherein when the flanged projection is positioned through the lens opening, the retainer is slidable laterally between an engaged position in which the retainer is secured to the retainer engagement feature of the frame holder and a disengaged position in which the retainer and frame holder may be separated.

2. The eyewear lens attachment assembly of claim 1 , wherein the frame attachment feature comprises a channel sized to receive a brow portion of an eyewear frame.

3. The eyewear lens attachment assembly of claim 2 , wherein the channel extends generally horizontally between first and second ends of the frame holder.

4. The eyewear lens attachment assembly of claim 1 , wherein the retainer engagement feature comprises an opening.

5. The eyewear lens attachment assembly of claim 4 , wherein the opening comprises a larger portion and a smaller portion.

6. The eyewear lens attachment assembly of claim 1 , wherein the slidable retainer is slidable between the engaged position and the disengaged position in a generally horizontal direction.

7. The eyewear lens attachment assembly of claim 1 , wherein the slidable retainer is slidable between the engaged position and the disengaged position in a generally vertical direction.

8. The eyewear lens attachment assembly of claim 1 , wherein the slidable retainer contacts the frame holder when in an engaged position.

9. The eyewear lens attachment assembly of claim 1 , further comprising a frame and a head-wearable electronic device.

10. The eyewear lens attachment assembly of claim 1 , wherein the slidable retainer comprises first and second portions joined by a living hinge.

11. The eyewear lens attachment assembly of claim 1 , wherein the slidable retainer comprises first and second portions joined by a threaded fastener.

12. An eyewear lens attachment assembly, comprising:
a lens having a lens opening proximate a nose region;
a frame holder comprising a channel sized to receive a brow portion of an eyewear frame and an opening, the opening comprising a larger portion and a smaller portion; and
a slidable retainer including an outer surface, an inner surface, and a flanged projection extending outwardly from the inner surface;
wherein the retainer is slidable between an engaged position in which the slidable retainer is secured to the frame holder and a disengaged position in which the retainer and frame holder may be separated by passing the flanged projection through the larger portion of the opening of the frame holder.

13. The eyewear lens attachment assembly of claim 12 , wherein the frame holder comprises a recess at least partially behind the opening, and a portion of the slidable retainer resides in the recess when the slidable retainer is in the engaged position.

14. The eyewear lens attachment assembly of claim 12 , wherein the slidable retainer is slidable between the engaged position and the disengaged position in a generally horizontal direction.

15. The eyewear lens attachment assembly of claim 12 , wherein the slidable retainer is slidable between the engaged position and the disengaged position in a generally vertical direction.
