Abstract
Foldable eyewear includes first and second lens rims, a bridge portion between the first and second lens rims, connectors between the bridge and the first and second lens rims, and at least one spring positioned at a folding hinge that rotatably joins the bridge portion and a lens rim-bridge connector. The spring-hinged mechanism that joins the bridge portion and a lens rim-bridge connector allows the user to fold one lens rim on top of the other for compact storage while preventing unwanted instability and unwanted transitions between the folded and unfolded positions. The spring-hinged mechanism allows the lens rim-bridge connector to “hyper-extend” relative to the bridge portion to absorb impact/force without breaking.
Claims15
Foldable eyewear, comprising:
- a bridge;
- a first lens rim;
- a second lens rim;
- a first lens rim-bridge connector rotatably connecting said first lens rim to said bridge, said first lens rim-bridge connector having a cavity that houses a compressed spring, said compressed spring exerting force against said bridge to provide a stable hinged connection between said first lens rim and said bridge;
- and
- a second lens rim-bridge connector rotatably connecting said second lens rim to said bridge, wherein said first and second lens rims rotate relative to said bridge to be substantially parallel,
- wherein said hinged connection between said first lens rim-bridge connector and said bridge is configured for rotation of said first lens rim-bridge connector from an unfolded position, in which said first lens rim-bridge connector is aligned with said bridge, to a folded position, in which said first lens rim-bridge connector is substantially perpendicular to said bridge, said hinged connection between said first lens rim-bridge connector and said bridge further being configured for rotation of said first lens rim-bridge connector from said unfolded position, in an opposite rotation direction than the rotation direction for reaching said folded position, to a hyper-extended position.
Foldable eyewear, comprising:
- a bridge;
- a first lens rim;
- a second lens rim;
- a first lens rim-bridge connector rotatably connecting said first lens rim to said bridge;
- and
- a second lens rim-bridge connector rotatably connecting said second lens rim to said bridge, wherein
- said first and second lens rims rotate relative to said bridge to be substantially parallel,
- said bridge includes a cavity that houses a compressed spring, said compressed spring exerting force against said first lens rim-bridge connector to provide a stable hinged connection between said first lens rim-bridge connector and said bridge, and
- said hinged connection between said first lens rim-bridge connector and said bridge is configured for rotation of said first lens rim-bridge connector from an unfolded position, in which said first lens rim-bridge connector is aligned with said bridge, to a folded position, in which said first lens rim-bridge connector is substantially perpendicular to said bridge, said hinged connection between said first lens rim-bridge connector and said bridge further being configured for rotation of said first lens rim-bridge connector from said unfolded position, in an opposite rotation direction than the rotation direction for reaching said folded position, to a hyper-extended position.
