Glasses with stem locks
View Patent ↗An eye wear system comprising a frame configured to receive at least one lens, with stems pivotably coupled to the frame, wherein stems have a first portion and a second portion, and a first, i.e. open, orientation disposed generally perpendicular to the frame, and a second, i.e. collapsed, orientation disposed generally parallel to the frame. The nose pads, which can be integrally formed with the frame, form at least part of an opening configured to receive the first portion of the stem to releasably secure the stem in the second, or collapsed, orientation.
1. An eye wear system comprising:
a frame configured to receive at least one lens;
at least one stem pivotably coupled to the frame, the at least one stem having a first portion and a second portion, the at least one stem having a first orientation disposed generally perpendicular to the frame, and a second orientation disposed generally parallel to the frame;
at least one nose pad disposed on the frame;
wherein the at least one nose pad forms at least part of an opening configured to receive the first portion of the at least one stem to releasably secure the at least one stem in the second orientation;
wherein the opening is curved to help guide the stem upwardly into the opening; and
wherein nose pad is adapted to maintain the stem in the opening until the stem is depressed downwardly and out of the opening.
2. The eye wear system of claim 1 , wherein the nose pad and the frame are an integral single-piece structure.
3. The eye wear system of claim 1 , wherein the opening is configured as a slot.
4. The eye wear system of claim 3 , wherein the slot extends in a plurality of planes.
5. The eye wear system of claim 4 , wherein the slot extends a first distance generally perpendicular to the frame and a second distance generally parallel to the frame.
6. The eye wear system of claim 5 , wherein the second distance is greater than the first distance.
7. The eye wear system of claim 1 , wherein the opening is disposed proximate a bottom of the nose pad.
8. The eye wear system of claim 1 , wherein a first and second stem are disposed in an overlapping manner when in the second orientation.
9. The eye wear system of claim 1 , wherein the frame and at least one nose pad is made of plastic, carbon graphite, acetate, or combinations thereof.
10. The eye wear system of claim 1 , wherein at least one portion of the at least one stem is made of a material having shape-memory characteristics.
11. The eye wear system of claim 1 , wherein the first portion of the stem is made of titanium or stainless steel.
12. The eye wear system of claim 1 , wherein the second portion of the stem is made of plastic or acetate.
13. The eye wear system of claim 1 , wherein the second portion of the stem is configured to engage the ear of a user when in the first orientation.
14. The eye wear system of claim 1 , wherein the at least one stem is coupled to the frame by a hinge.
15. The eye wear system of claim 1 , wherein the at least one stem is coupled to the frame by a spring.
16. The eye wear system of claim 1 , wherein the at least one stem is maintained in a generally non-linear shape when in the second orientation.
17. The eye wear system of claim 3 , wherein a portion of the frame comprises a side of the slot and wherein the frame is curved to help guide the stem into the second orientation.
18. The eye wear system of claim 1 , wherein the first and second portions of the stem are an integral single-piece structure.
