Pinless hinge for eyewear
View Patent ↗Eyewear comprising a lens frame, at least one temple or ear piece, and at least one hinge. The hinge may be a substantially C-shaped wire with two end portions inserted through axially aligned pairs of holes formed into the lens frame and the temple. Alternatively, the hinge may be omitted and a hinge faceplate having a vertical rod portion integrally formed thereto may be coupled with the lens frame and the temple. Specifically, the temple may have a protrusion mating with a depression formed into the lens frame and the temple may have a depression formed therein mating with a rod end of the vertical rod portion, such that a portion of the temple is sandwiched between and rotatable relative to the vertical rod portion of the hinge faceplate and the lens frame.
1. Eyewear comprising:
a lens frame having a first pair of spaced apart holes formed therein,
a temple having an inner surface, an outer surface opposite the inner surface, and a second pair of spaced apart holes formed therein, wherein the inner surface of the temple faces the lens frame and the outer surface of the temple faces away from the lens frame; and
a hinge comprising:
a curved flexible member having:
a first end portion disposed in one of the first pair of holes and one of the second pair of holes;
a second end portion disposed in another one of the first pair of holes and another one of the second pair of holes; and
a curved portion between the first end portion and the second end portion,
wherein at least one of the temple and the lens frame is pivotable or rotatable about the flexible member.
2. The eyewear of claim 1 , wherein the flexible member is movable between a compressed position in which the first and second end portions are a first distance away from each other and an uncompressed position in which the first and second end positions are a second greater distance away from each other.
3. The eyewear of claim 2 , wherein the end portions are substantially axially aligned with each other in at least one of the compressed and uncompressed positions.
4. The eyewear of claim 1 , wherein the curved portion is fixedly secured to at least one of the temple and the lens frame.
5. The eyewear of claim 1 , wherein the first end portion is angled in an opposite direction away from the second end portion.
6. The eyewear of claim 1 , wherein the curved portion is substantially c-shaped, omega symbol-shaped, horseshoe shaped, or U-shaped.
7. The eyewear of claim 1 , further comprising a faceplate having a front surface and a back surface, wherein the back surface of the faceplate is configured to mate with the outer surface of the temple such that the curved portion of the flexible member rests between the faceplate and the temple.
8. The eyewear of claim 7 , wherein the faceplate further comprises an attachment receptacle extending from the back surface of the faceplate and configured to receive and attach to a mechanical attachment extending through the temple.
9. The eyewear of claim 7 , wherein the faceplate further comprises a biasing protrusion extending from the back surface of the faceplate and positioned between the first and second end portions of the flexible member such that the biasing protrusion prevents the end portions from compressing toward each other.
10. The eyewear of claim 7 , wherein a guide hole or channel is formed into the outer surface of the temple proximate a location of the flexible member, wherein the faceplate further comprises a secondary attachment protrusion extending from the back surface of the faceplate and mated with the guide hole or channel formed in the temple.
11. The eyewear of claim 1 , wherein the holes of at least one of the first pair of spaced apart holes and the second pair of spaced apart holes are axially aligned with each other.
12. Eyewear comprising:
a lens frame having a first pair of spaced apart holes formed therein,
a temple having an inner surface, an outer surface opposite the inner surface, and a second pair of spaced apart holes formed therein, wherein the inner surface of the temple faces the lens frame and the outer surface of the temple faces away from the lens frame;
a hinge comprising:
a curved flexible member having:
a first end portion disposed in one of the first pair of holes and one of the second pair of holes;
a second end portion disposed in another one of the first pair of holes and another one of the second pair of holes; and
a curved portion between the first end portion and the second end portion,
wherein at least one of the temple and the lens frame is pivotable or rotatable about the flexible member;
a faceplate having a front surface and a back surface, wherein the back surface of the faceplate is configured to mate with the outer surface of the temple such that the curved portion of the flexible member rests between the faceplate and the temple; and
a mechanical fastener extending through the temple and attached to the faceplate.
