Abstract

The invention relates to eyeglasses having two lens units that are fitted with a device for keeping the eyeglasses on a wearer's head. The eyeglasses having a nose bridge that connects the two lens units and includes a central portion to be disposed about the wearer's nose At least one of the lens units has a duct inside to which a lateral portion of the nose bridge is slidingly mounted using a mechanism for adjusting the position of the lens unit relative to the nose bridge. The adjusting mechanism has a member that is rotatably mounted in the duct. The member and the lateral portion of the nose bridge comprise a coupler designed to convert the rotation of the member into a relative translational movement between the lateral portion and the duct.

First claim

What is claimed is:

1. Eyeglasses comprising two lens units that are equipped with a retaining device for keeping the eyeglasses on a wearer's head, as well as a nose bridge that connects the units while having a central portion intended to be positioned about the wearer's nose, at least one of the units being equipped with a duct inside which a lateral portion of the nose bridge is mounted to an adjusting device for positioning of the lens unit relative to the nose bridge, the eyeglasses wherein the adjusting device comprises a member that is rotatably mounted in the duct, the member and the lateral portion of the nose bridge comprising a coupler adapted to convert the rotation of the member into a relative translational movement between the lateral portion and the duct.

2. The eyeglasses according to claim 1 wherein the coupler comprises a thread and a tapping formed on respectively one of either the member and the lateral portion of the nose bridge.

3. The eyeglasses according to claim 1 , wherein the member comprises an actuating head for actuating the rotation thereof in the duct.

4. The eyeglasses according to claim 3 , wherein the duct has a lower opening through which the actuating head can be accessed, as well as an upper opening from which the central portion of the nose bridge extends.

5. The eyeglasses according to claim 3 , wherein the actuating head comprises a recess adapted to allow the member to be rotatably actuated by a tool.

6. The eyeglasses according to claim 1 , wherein the adjusting device comprises a means for viewing the position of the lateral portion in the duct.

7. The eyeglasses according to claim 1 , wherein the duct has a slot that opens out laterally, the lateral portion having a slider that is arranged inside the slot.

8. The eyeglasses according to claim 1 , wherein the translational movement of the member in the duct is blocked, and the rotational movement of the lateral portion in the duct is blocked.

9. The eyeglasses according to claim 1 , wherein the retaining device incorporates a tool for actuating the rotational movement of the member in the duct.

10. The eyeglasses according to claim 9 , wherein the retaining device comprises at least one strap equipped with a fastener that carries the tool that is capable of being deployed to allow for the use thereof.

11. The eyeglasses according to claim 10 , wherein the retaining device comprises two straps, each of which is equipped with a fastener that carries the tool and a housing respectively, the fasteners being secured to one another so as to allow the tool to be displaced between a deployed position of use and a stowed position inside the housing.

12. The eyeglasses according to claim 11 , wherein the fasteners are secured to one another in rotation, at the level of a rotational axis of the tool between the deployed and stowed positions thereof.

13. The eyeglasses according to claim 11 , wherein each of the fasteners comprises a rigid buckle in which a free end of a strap slides in order to allow the length of the strap to be adjusted.

14. The eyeglasses according to claim 1 , wherein each lens unit comprises a transparent wall, the rear periphery whereof is equipped with a seal intended to mould to the wearer's face.

15. The eyeglasses according to claim 1 , wherein each lens unit has an inner edge equipped with a duct in which a lateral portion of the nose bridge is mounted such that it slides via an adjusting device so as to be able to adjust the relative positioning of the units on the nose bridge.

16. The eyeglasses according to claim 1 , wherein the duct is formed on an inner edge of a lens unit, the duct having a longitudinal axis (A) forming an angle α that lies in the range from 30° to 60° with a vertical plane (S) of symmetry of the eyeglasses.

17. The eyeglasses according to claim 16 , wherein the longitudinal axis (A) of the duct forms an angle β that lies in the range from 1° to 10° with a median plane (M) of the lens unit.
