Abstract

The invention relates to a binocular device for displaying information, the device comprising a support for placing on the nose and supporting a right display element and a left display element each designed to be placed in front of an eye and each comprising a light guide for receiving a beam of light rays emitted by a beam generator device towards an inlet face and for propagating the beam to an outlet face where the beam is directed towards the corresponding eye, the binocular device having an arrangement for adjusting the pupillary distance by moving at least one of the light guides relative to said support so as to adjust the distance between the light guides. According to the invention, said light guides are disposed over a said support and are held by a strip disposed over the light guides and secured to said support by means of at least one spacer, at least one slack takeup means being interposed between said strip and said light guides.

Claims

1. A binocular device for displaying information, the device comprising:

a support for placing on the nose and supporting a right display element and a left display element each designed to be placed in front of an eye and each comprising a light guide for receiving a beam of light rays emitted by a beam generator device towards an inlet face and for propagating the beam to an outlet face where the beam is directed towards the corresponding eye,

the binocular device having an arrangement for adjusting the pupillary distance by moving at least one of the light guides relative to said support so as to adjust the distance between the light guides,

wherein said light guides are disposed over a said support and are held by a strip disposed over the light guides and secured to said support by means of at least one spacer, at least one slack takeup means being interposed between said strip and said light guides.

2. A binocular device according to claim 1, wherein said slack takeup means comprises a compliance element interposed between said strip and each light guide.

3. A binocular device according to claim 1, including a cover part connected to said support and enclosing the light guides and said strip.

4. A binocular device according to claim 1, including, facing said outlet faces of said light guides, respective devices for supporting eyesight-correcting lenses.

5. A binocular device according to claim 1, wherein said arrangement for adjusting the pupillary distance is a rail and slideway arrangement carried respectively by said support and by said respective light guide.

6. A binocular device according to claim 5, wherein said slideway is comprises a plate of T-shaped cross-section and secured to said light guide.

7. A binocular device according to claim 5, wherein said rail is shaped in said support.

8. A binocular device according to claim 1, wherein said adjustment arrangement presents a device that can be actuated from the outside, manually or under motor drive.

9. A device according to claim 6, wherein said adjustment arrangement presents a device that can be actuated from the outside, manually or under motor drive, and wherein said actuatable device includes a screw-and-nut device connected to said plate and capable of being actuated through a lateral orifice arranged in said support.
