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.

Claims (15)

  1. Eyewear (100), comprising: - a frame (105); - an optical member supported by the frame (105); - a temple (125A); - a hinge (1001) coupled between the frame (105) and the temple (125A), the hinge (1001) configured to allow rotation of the temple (125A) with respect to the frame (105); - a cosmetic trim coupled to the temple and including a recess (1004); and - a cam configured to leverage the cosmetic trim and the temple away from the frame when the temple is in a hyperextended position.
  2. The eyewear (100) of claim 1, further comprising an electrical conductor coupled to the hinge (1001), the electrical conductor having a first service loop (1026) configured to allow the electrical conductor to extend when the temple (125A) extends away from the hinge (1001) to the hyperextended position, and a second service loop (1034) configured to allow the electrical conductor to extend when the temple (125A) is rotated about the hinge (1001).
  3. The eyewear (100) of claim 2, wherein the hinge (1001) is interposed between the first service loop (1026) and the second service loop (1034).
  4. The eyewear (100) of claim 3, wherein the electrical conductor is secured to the hinge (1001) between the first service loop (1026) and the second service loop (1034).
  5. The eyewear (100) of claim 2, wherein the electrical conductor comprises a flexible printed circuit (1022) secured between the first service loop (1026) and the second service loop (1034).
  6. The eyewear (100) of claim 1, further comprising a protrusion (1002) between the frame (105) and the temple (125A) configured to create a gap between the temple (125A) and the frame (105) in the hyperextended position.
  7. The eyewear (100) of claim 6, wherein the cam also creates the gap in the hyperextended position.
  8. The eyewear (100) of claim 6, wherein the recess (1004) is configured to receive the protrusion (1002) when the temple (125A) is in an open position.
  9. The eyewear (100) of claim 1, further comprising an extension member (1010) configured to allow the temple (125A) to extend away from the hinge (1001) to the hyperextended position.
  10. The eyewear (100) of claim 9, wherein the extension member (1010) is coupled to the hinge (1001), wherein the temple (125A) is configured to extend along the extension member (1010) when extended to the hyperextended position.
  11. The eyewear (100) of claim 10, further comprising a limit member (1016) configured to limit a travel distance of the temple (125A) along the extension member (1010).
  12. The eyewear (100) of claim 9, wherein the extension member (1010) comprises a bushing (1014) coupled to the temple (125A), the bushing (1014) containing a spring (1012) configured to extend about the extension member (1010).
  13. The eyewear (100) of claim 12, wherein the spring (1012) is configured to enable the temple (125A) to radially extend from the hinge (1001), and also create a bias force to retract the temple (125A) toward the hinge (1001).
  14. The eyewear (100) of claim 12, wherein the spring (1012) is configured to compress against the bushing (1014) when the bushing (1014) is extended from the hinge (1001), and create a bias force configured to retract the temple (125A) toward the hinge (1001).
  15. The eyewear (100) of claim 12, wherein the spring (1012) is at least partially within the bushing (1014).
