Abstract
Eyeglasses that can be hung around the wearer's neck, without the necessity of a chain or cord, can be rotated between a normal viewing position, a conventional storage position and a hanging position. In the hanging positions, the rear ends of temple arms are spaced apart by a distance less than the diameter of a normal wearer's neck. In embodiment in which a hinge between the lens frame and the temple arms can be pivoted about three orthogonal axes, the lens frame will lie flat against the wearer's chest or neck. Two hinge configurations that allow the lens frame to lie flat include a ball and socket joint and a multiple hinge joint. The temple arms can also be extended so that the eyeglasses will more comfortably fit around the wearer's neck in the hanging position.

Eyeglasses comprising a front lens frame and a pair of temple arms and hinges between the front lens frame and each temple arm so that the temple arms can be folded about the hinges from a normal viewing position into a storage position with the temple arms folded behind the front lens frame, the eyeglasses also being characterized in that the temple arms can be folded about the hinges from a normal viewing position relative to the front lens frame into a hanging position in which the temple arms extend transversely relative to a position occupied by the temple arms in the storage position with ear gripping sections of the temple arms extending inwardly toward each other when in the hanging position so that the ear gripping sections can extend behind a wearer's neck to hold the eyeglasses around the wearer's neck.
Eyeglasses comprising a front lens frame and a pair of temple arms hinged relative to the front lens frame about ball and socket joints at each end of the front lens frame so that the temple arms are foldable about the ball and socket joints from a normal viewing position into a storage position with the temple arms folded behind the front lens frame and are foldable about the ball and socket joints from a normal viewing position into a hanging position in which ear gripping sections extend toward each other behind a wearer's neck to hold the eyeglasses around the wearer's neck.
Eyeglasses including a pair of temple arms each connected to a lens frame by a ball and socket joint, each ball and socket joint including a socket attached to the lens frame and a ball attached to a corresponding temple arm by a ball stem, each socket including first and second mutually perpendicular notches providing clearance for the corresponding ball stem when the temple arms are folded about mutually perpendicular axes so that the temple arms can be folded into a storage position or into a hanging position.
