Eyeglasses comprising electrical and/or electronic elements

1. Eyeglasses comprising:

a front frame ( 1 ) to which two side arms ( 2 ) are connected; and

electric or electronic elements ( 5 ) connected to each other by an electric circuit ( 6 ),

wherein said electric circuit is composed at least partially of at least one flexible printed circuit ( 6 ), which is housed into a seat ( 3 ) formed at least partially inside said front frame ( 1 ) and at least partially inside at least one of the two side arms ( 2 ).

2. The eyeglasses according to claim 1 , wherein said electric or electronic elements comprise one or more batteries ( 7 ) housed into predetermined housing compartments ( 20 ) formed into one or both of said arms ( 2 ) or said front frame ( 1 ), and wherein said electric circuit comprises a single flexible printed circuit ( 6 ), said electric or electronic elements being connected thereto or integrated thereon.

3. The eyeglasses according to claim 2 , wherein there are provided at least two batteries ( 7 ) housed into at least two predetermined housing compartments ( 20 ) formed into each one of said two side arms ( 2 ), said flexible printed circuit ( 6 ) being housed into a seat ( 3 ) formed into said front frame ( 1 ) and into both of said side arms ( 2 ).

4. The eyeglasses according to claim 3 , wherein said seat has a thickness corresponding to a thickness of said flexible printed circuit.

5. The eyeglasses according to one- claim 1 , wherein said arms are at least partially made of a rigid material.

6. The eyeglasses according to claim 1 , wherein said electric or electronic elements comprise one or more LEDs ( 5 ).

7. The eyeglasses according to claim 1 , wherein said electric or electronic elements comprise one or more of a sensor, a processor, a remote communication unit, a display, or a sound speaker.

8. Eyeglasses comprising:

a front frame ( 1 ) to which two side arms ( 2 ) are connected; and

electric or electronic elements ( 5 ) connected to each other by an electric circuit ( 6 ), wherein said electric circuit is composed at least partially of at least one flexible printed circuit ( 6 ), which is housed into a seat ( 3 ) formed at least partially inside said front frame ( 1 ) and at least partially inside at least one of the two side arms ( 2 ); and

hinges provided at areas connecting said side arms ( 2 ) and the front frame ( 1 ), said hinges articulating said side arms ( 2 ), such that each arm ( 2 ) is pivotally movable about a pivot axis ( 41 ) substantially perpendicular to a longitudinal axis of the arm ( 2 ) and to an interpupillary line when the eyeglasses are worn, from an extreme folding position wherein said arm ( 2 ) is oriented collapsed against a rear side of the front frame ( 1 ) to an extreme deployment position wherein said arm is moved away from the other one of said two arms and it substantially transverse to an extension of the front frame ( 1 ),

wherein at least one of said hinges ( 4 ) is shaped to be provided, at an extrados side, with a first, curved and seamless resting surface ( 40 ), such that, when pivoting the arm ( 2 ) from said extreme deployment position to said extreme folding position, said resting surface ( 40 ) contacts a larger and larger portion of said printed circuit ( 6 ), pulling out a predetermined portion of said printed circuit ( 6 ) from one or both of said front frame ( 1 ) or said arm ( 2 ) by dragging.

9. The eyeglasses according to claim 8 , wherein said seat ( 3 ) housing said flexible printed circuit ( 6 ) in one or both of said front frame ( 1 ) or at least one arm ( 2 ) has at least a widening ( 30 ) intended to house said predetermined portion of said flexible printed circuit ( 6 ) when the arm ( 2 ) is in the deployment position.

10. The eyeglasses according to claim 9 , wherein said widening ( 30 ) is provided with a second curved and seamless resting surface ( 33 ) such that, in the extreme deployment position of the arm ( 2 ), said predetermined portion of the flexible printed circuit ( 6 ) is fitted into said widening ( 30 ) causing said flexible printed circuit ( 6 ) to bend, such that a convex side of said flexible printed circuit ( 6 ) contacts at least partially said second resting surface ( 33 ).

11. The eyeglasses according to claim 10 , wherein said widening ( 30 ) is provided with a third curved and seamless resting surface ( 34 ) such that, in the extreme folding position of the arm ( 2 ), said predetermined portion of the flexible printed circuit ( 6 ) is pulled out from said widening ( 30 ), causing said flexible printed circuit to extend, such that a concave side of said flexible printed circuit ( 6 ) contacts at least partially said third resting surface ( 34 ).

12. The eyeglasses according to claim 11 , wherein one or more of said first resting surface ( 40 ), said second resting surface ( 33 ), or said third resting surface ( 34 ) have such radii of curvature that said flexible printed circuit ( 6 ) is prevented from being permanently bent in a resting condition on said first resting surface ( 40 ), said second resting surface ( 33 ), or said third resting surface ( 34 ).
