Rimless eye wear
View Patent ↗A simplified rimless or semi-frame eyewear is disclosed. The eyewear comprises a frame and a pair of lenses that slide into or engage a slotted connection in the frame. The lenses are held in place in a corresponding frame with a locking design or an adhesive. An example of a locking mechanism is a screw connector that may be incorporated into the frame to lock the lens in place.
1. A rimless eyewear comprising:
a frame section comprising:
a bridge section;
a left section; and
a right section, the left section and the right section attached to opposite ends of the bridge section, each of the left section and the right section comprising a slot formed therein, the slot extending from substantially a free end of a corresponding section to substantially the bridge section, wherein a width of a lower edge of a corresponding slot is less than the width of the slot,
flexible lining element contained within each of the left section slot and the right section slot, said lining element covering an inner surface of a corresponding slot; and
a first lens configured to attach to the left section; and
a second lens configured to attach to the right section, each of the first lens and the second lens includes an engagement means formed along a corresponding upper edge wherein the engagement means is configured to:
engage the flexible lining element within a corresponding slot from substantially the free end of the corresponding section to substantially the bridge section to retain a corresponding one of the first lens and the second lens therein; and
a retaining means configured to retain the first lens and the second lens in corresponding ones of the left section and the right section.
2. The eyewear of claim 1 , wherein the lining element is one of: a rubber material, a neoprene material, and a silicon material.
3. The eyewear of claim 1 , wherein the slot in each of the left section and the right section is one of: a T-slot, a dovetail, and an O-ring.
4. The eyewear of claim 3 , wherein the engagement means on a corresponding lens is a corresponding one of: a T-slot, a dovetail, and an O-ring.
5. The eyewear of claim 4 , wherein the dovetail comprises a front facet angle and a rear facet angle that are one of: equal and different.
6. The eyewear of claim 1 , the retaining means is one of: an adhesive, a heat-sensitive polymer material, a screw and a clip.
7. The eyewear of claim 1 , wherein the engagement means is a snap-fit connection between the slot in a corresponding one of the left section and the right section.
8. The eyewear of claim 1 , wherein the slot in a corresponding one of the left section and the right section comprises:
a protrusion extending from a lower edge of a first inner surface the slot; and
a flat surface; and
the engagement means comprises a groove within a corresponding lens, wherein the groove within the lens engages the protrusion in the slot.
9. The eyewear of claim 1 , wherein the slot in a corresponding one of the left section and the right section comprises:
a groove in a first inner surface the slot; and
a flat opposite second surface; and
the engagement means comprises a protrusion on a corresponding lens, wherein the protrusion of the lens engages the groove in the first inner surface.
10. An eyewear configuration comprising:
a frame comprising:
a first section and a second section joined together by a bridge element, the bridge element including a nose element extending downward therefrom, each of the first section and the second section including a slot therein, wherein a width of an entrance to the slot is narrower than a width of the slot;
a flexible insert material along inner surface of each of the first section slot and the second section slot; and
a lens associated with each of the first section and the second section, each lens comprising:
a main portion; and
a deformation of the main portion along an upper section of the main portion, wherein the deformation decreases a width of the main portion, the decrease in width being comparable to the width of the slot entrance.
11. The eyewear of claim 10 , wherein the width of the slot is narrowed by at least one protrusion extending from a corresponding lower edge of the frame.
12. The eyewear of claim 11 , wherein the at least one protrusion is one of: a square protrusion, a triangular protrusion and a rounded protrusion.
13. The eyewear of claim 10 , wherein an upper edge of each lens includes a chamfer.
14. The eyewear of claim 13 , wherein an upper interior edge of each of the first section and the second section of the frame includes a chamfer.
15. The eyewear of claim 10 , wherein the insert material is one of: a rubber, a silicon, and a neoprene.
16. The eyewear of claim 10 , wherein the slot extends substantially a length of a corresponding one of the first section and the second section.
17. The eyewear of claim 10 further comprising:
a retaining element configured to retain the lens within a corresponding slot.
