Abstract

An electronic frame for an optical device, the frame including a front frame element able to partially house at least one lens and including at least one electronic component, the front element extending, on either side of said at least one lens, over a retained length of said at least one lens. The front element includes a reinforcing element extending at least substantially over all said retained length of said at least one lens.

First claim

The invention claimed is:

1. An electronic frame for an optical device, the electronic frame comprising:
a front frame element configured to partially house at least one lens;
a cradle configured to at least partially encircle a lower portion of the at least one lens;
a reinforcing element; and
at least one electronic component,
the front frame element extending, on either side of the at least one lens, over a retained length of the at least one lens,
the reinforcing element extending at least substantially over all the retained length of the at least one lens,
the front frame element, the reinforcing element and the cradle being separate pieces, the front frame element being a holder configured to house an upper portion of the at least one lens, and
the reinforcing element retaining the holder via fastening with the cradle, the reinforcing element having a U-shaped cross section forming a housing accommodating the holder and the electronic component fastened to the holder, thus enclosing the holder between the reinforcing element and the cradle.

2. The electronic frame as claimed in claim 1 , further comprising: two temples connected by a hinge at two ends of the front frame element, wherein the reinforcing element extends between the two ends of the front frame element.

3. The electronic frame as claimed in claim 1 , wherein the reinforcing element is integrally formed with the front frame element.

4. The electronic frame as claimed in claim 1 , wherein the reinforcing element is added to the front frame element.

5. The electronic frame as claimed in claim 4 , wherein the front frame element is made from a flexible material.

6. The electronic frame as claimed in claim 5 , wherein the flexible material is a thermoplastic elastomer.

7. The electronic frame as claimed in claim 1 , wherein the reinforcing element is made from at least one of materials belonging to the following group: aluminum alloy, magnesium alloy, titanium alloy or carbon fibers.

8. The electronic frame as claimed in claim 1 , wherein the holder and the cradle are made of different materials.

9. The electronic frame as claimed in claim 1 , wherein the holder and the cradle are a single part made of a given material.

10. An optical device comprising:
the electronic frame according to claim 1 ; and
at least one fragile lens.
