Abstract

Eyewear having a frame, a hinge, and a hyperextendable temple having a flexible printed circuit (FPC) including service loops. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. A first service loop allows extension of the FPC when the temple rotates about the hinge, and a second service loop allows the temple to be radially extended away from the hinge.

First claim

What is claimed is:

1. Eyewear, comprising:
a frame;
an optical member supported by the frame;
a temple including a recess;
a hinge coupled between the frame and the temple, the hinge configured to allow rotation of the temple with respect to the frame; and
a protrusion configured to create a cam and the recess is configured to receive the protrusion only when the temple is in a single open position and between the single open position and a hyperextended position, wherein the recess is configured such that it does not abut any portion of the protrusion when the temple is in a closed position and in the hyperextended position.

2. The eyewear of claim 1 , wherein the cam is configured to prevent an edge of the temple from engaging the frame.

3. The eyewear of claim 1 , wherein the recess is commensurate in shape and size with the protrusion.

4. The eyewear of claim 3 , wherein the protrusion is elongated with rounded edges.

5. The eyewear of claim 1 , wherein the frame comprises a hinge cap encompassing the hinge.

6. The eyewear of claim 1 , wherein the temple comprises a trim, wherein the recess is located on the trim.

7. Eyewear, comprising:
a frame comprising a frame surface;
an optical member supported by the frame;
a temple comprising a temple surface including a recess;
a hinge coupled between the frame and the temple, the hinge configured to allow rotation of the temple with respect to the frame; and
a protrusion extending from a midsection of the frame surface, wherein the protrusion is configured to create a cam and the recess is configured to receive the protrusion when the temple is in an open position, further including a hinge cap comprising a flange, and the protrusion extends from the flange.

8. Eyewear, comprising:
a frame;
an optical member supported by the frame;
a first temple portion extending from the frame and comprising a first temple surface;
a second temple portion comprising a second temple surface including a recess;
a hinge coupled between the first temple portion and the second temple portion, the hinge configured to allow rotation of the second temple portion with respect to the first temple portion; and
a protrusion extending from a midsection of the first temple surface, wherein the protrusion is configured to create a cam and the recess is configured to receive the protrusion when the second temple portion is in an open position, further including a hinge cap comprising a flange, and the protrusion extends from the flange.
