Mounting mechanism for eyewear

1. Eyewear comprising:

at least one lens;

at least one earstem;

a retention assembly comprising an engagement protrusion attached to the lens and a coupling mechanism attached to an end of the earstem, the engagement protrusion configured to be fixed relative to the lens, the coupling mechanism comprising:

a housing configured to receive the engagement protrusion;

a lever mechanism being operative to move between open and closed positions for disengaging or engaging with the engagement protrusion; and

a biasing mechanism configured to urge the lever mechanism at least into a closed position.

2. The eyewear of claim 1 , wherein the engagement protrusion comprises an interlocking portion configured to interconnect with a corresponding engagement portion of the lever mechanism when the lever mechanism is in the closed position to securely mount the earstem relative to the lens.

3. The eyewear of claim 2 , wherein the engagement portion of the lever mechanism is configured to slide over the interlocking portion and rotate to the closed position to securely mount the earstem relative to the lens.

4. The eyewear of claim 1 , wherein the lever mechanism is rotatably mounted relative to the housing to allow the lever mechanism to move between open and closed positions for disengaging or engaging with the engagement protrusion.

5. The eyewear of claim 4 , wherein the lever mechanism is rotatably and slidably mounted relative to the housing to allow the lever mechanism to move between open and closed positions for disengaging or engaging with the engagement protrusion.

6. The eyewear of claim 5 , wherein the coupling mechanism further comprises an interconnecting block disposed within the housing and rotatably coupled to both the lever mechanism and housing, wherein the interconnecting block is configured to move between an extended position and a contracted position to provide a linear sliding movement of the lever mechanism.

7. The eyewear of claim 4 , wherein the lever mechanism comprises a sliding mechanism, wherein the sliding mechanism comprises the biasing mechanism and a locking structure configured to be engaged with the engagement protrusion.

8. The eyewear of claim 1 , wherein the lever mechanism is moveable from the open position towards the closed position in an anterior direction.

9. The eyewear of claim 1 , wherein the eyewear is configured to be frameless.

10. Eyewear comprising:

at least one lens;

at least one earstem;

a retention assembly configured to releasably secure the lens relative to the earstem comprising an engagement protrusion attached to the lens and a coupling mechanism attached to an end of the earstem, the engagement protrusion being fixed relative to the lens, the coupling mechanism comprising:

a housing configured to receive the engagement protrusion;

a lever mechanism configured to rotate about a fixed axis of rotation between open and closed positions for disengaging or engaging with the engagement protrusion; and

a biasing mechanism configured to urge the lever mechanism at least into a closed position.

11. The eyewear of claim 10 , wherein the lever mechanism is rotatable from the open position towards the closed position in an anterior direction.

12. The eyewear of claim 10 , wherein the engagement protrusion comprises an interlocking portion configured to interconnect with a corresponding engagement portion of the lever mechanism when the lever mechanism is in the closed position to securely mount the earstem relative to the lens.

13. The eyewear of claim 12 , wherein the engagement portion of the lever mechanism is configured to slide over the interlocking portion and rotate to the closed position to securely mount the earstem relative to the lens.

14. The eyewear of claim 10 , wherein the lever mechanism comprises a locking tab and a resilient material, wherein the resilient material allows the locking tab to deflect during rotation and engage with the engagement protrusion when the lever mechanism is in the closed position.

15. The eyewear of claim 10 , wherein the engagement protrusion comprises a wedge shape and an opening of the housing is configured to receive the engagement protrusion.

16. The eyewear of claim 10 , wherein the eyewear is configured to be frameless.
