Display for incorporating in a pair of eyeglasses
View Patent ↗The invention relates to a display comprising an optical imager ( 5 ) for shaping light beams emitted by a light beam generator system ( 4 ), said beams being introduced into said imager via an inlet face, and for directing the beams towards the eye (O) of a wearer in order to enable an image (I) to be viewed, two hooks ( 10, 11 ) being in reference positions relative to the imager, and said light beam generator system including a connection arrangement for connection to said hooks ( 10, 11 ), the connection between said system and said hooks being releasable and said hooks ( 10, 11 ) being designed to be received in housings carried by the connection arrangement. According to the invention, said housings are arranged in such a manner that said connection arrangement is assembled on said hooks by applying thrust against one of said hooks ( 11 ), by turning about said hook, and by snap-fastening onto the other hook ( 10 ).
1. A display comprising an optical imager for shaping light beams emitted by a light beam generator system, said beams being introduced into said imager via an inlet face, and for directing the beams towards the eye of a wearer in order to enable an image to be viewed, two hooks being in reference positions relative to the imager, and said light beam generator system including a connection arrangement for connection to said hooks, the connection between said system and said hooks being releasable and said hooks being designed to be received in housings carried by the connection arrangement, wherein said housings are arranged in such a manner that said connection arrangement is assembled on said hooks by applying thrust against one of said hooks, by turning about said hook, and by snap-fastening onto the other hook.
2. A display according to claim 1 , wherein said imager is incorporated in a lens of a pair of eyeglasses.
3. A display according to claim 2 , wherein said display includes a pusher element for pushing said connection arrangement against said hooks ( 10 , 11 ), said pushing being substantially perpendicular to the front face of said lens ( 9 ).
4. A display according to claim 3 , wherein said pusher element is a flexible blade carried by said generator system and thrusting against said lens while said connection arrangement is turning.
5. A display according to claim 2 , wherein said thrust on one of the hooks is linear thrust perpendicular to the front face of said lens.
6. A display according to claim 5 , wherein said linear thrust is associated with a skid for applying point thrust against said lens, the skid being arranged on the connection arrangement close to the housing providing said linear thrust.
7. A display according to claim 2 , wherein said hooks are disposed at respective different distances from a side edge of said lens.
8. A pair of eyeglasses having at least one lens including an incorporated imager and provided with two said hooks so as to form a display according to any one of claim 2 .
9. A display according to claim 1 , wherein each of said hooks is constituted by a sphere disposed at the end of a rod.
10. A display according to claim 9 , wherein the housing applying said linear thrust is formed by two projections carried by said connection arrangement and spaced apart from each other by a distance greater than the diameter of the rod of the hook.
11. A display according to claim 1 , wherein the housing providing said snap-fastening is formed by a clip carried by said connection arrangement.
12. A display according to claim 1 , wherein said hooks are anchored in bores arranged in said inlet face of said imager.
13. A display according to claim 1 , wherein said connection arrangement is machined or molded in a plate of said light beam generator system.
