Abstract

A hinge of the flex type for eyeglasses, the hinge having an internally hollow central hinge body, adapted to be coupled to a second body, which is also internally hollow and is adapted to be coupled to an eyeglasses temple, and to a third body adapted to be coupled to the front of the eyeglasses. It is possible to assemble the central body and the second and third body in a pack, in order to define internally the passage of a data/power cable, the central body allowing an accumulation of the data/power cable and ensuring the passage of the cable between the temple and the front without stretching and/or torsion.

First claim

The invention claimed is:

1. A hinge for eyeglasses comprising: an internally hollow central hinge body, adapted to be coupled to a second body, which is also internally hollow and is configured to be coupled to an eyeglasses temple, and to a third body configured to be coupled to a front of the eyeglasses, said central body and said second and third body being configured to be assembled in a pack, in order to define internally a passage of a data/power transmission cable, said central hinge body allowing an accumulation of the data/power cable and ensuring the passage of the data/power cable between the eyeglasses temple and the front of the eyeglasses, wherein said second body is C-shaped and configured to be coupled to said third body, with interposition of said central hinge body and elastic means, said second body being provided with a pair of eyelets adapted to be inserted into mutually opposite protrusions which are defined at said third body.

2. The hinge according to claim 1 , wherein said central hinge body and said second body are adapted to be accommodated within said eyeglasses temple.

3. The hinge according to claim 1 , wherein said third body is adapted to be accommodated within said front.

4. The hinge according to claim 1 , wherein said central hinge body has a pair of wings arranged like a fork and adapted to conceal completely from view said data/power cable.

5. The hinge according to claim 1 , wherein said data/power cable is a flexible PCB cable.

6. The hinge according to claim 1 , wherein said data/power cable passes around a cylindrical body of said third body that defines said protrusions, in order to be inserted into said front.

7. The hinge according to claim 1 , wherein said elastic means are interposed between said central hinge body and said second body.

8. The hinge according to claim 1 , wherein said central hinge body allows an undulated accumulation of said data/power cable, in order to define a cable stock in order to allow a folding of said eyeglasses temple with respect to said front and an extra rotation of said eyeglasses temple, without stretching and/or tearing of said data/power cable.

9. The hinge according to claim 1 , wherein said elastic means are configured to allow an over-rotation of the eyeglasses temple with respect to the front.

10. The hinge according to claim 1 , wherein said third hinge body has an inclined plane which is adapted to allow a sliding thereupon of said central hinge body when an over-rotation is performed of said eyeglasses temple with respect to said front.

11. The hinge according to claim 10 , wherein said inclined plane of said third body is hidden from view when said eyeglasses temple is in the position of normal opening with respect to said front.

12. The engine according to claim 10 , wherein said third body comprises, at an interface with said central hinge body, a portion that is perpendicular to a longitudinal axis of said eyeglasses temple, in the position of normal opening of the eyeglasses temple, which is connected with said inclined plane of said third body.

13. The hinge according to claim 10 , wherein said central hinge body comprises, at an interface with said third body, a portion that is perpendicular to a longitudinal axis of said temple, in the position of normal opening of the eyeglasses temple, which blends with an inclined plane that is complementary to the inclined plane of said third hinge body.

14. The hinge according to claim 1 , wherein said third body and said central hinge body, when said eyeglasses temple is in the normal open position with respect to said front, are coupled according to a profile of an external contact edge between the eyeglasses temple and the front that is not parallel to a rotation axis of the hinge.

15. Eyeglasses comprising at least one hinge according to claim 1 .
