Abstract

The invention relates to a pair of glasses allowing you to see in front and behind you. It consists of two optics, the part of which is neither concave nor convex (fig. 4) is partially treated as a one-way mirror, treated in the mass or by surfacing (dipping) (fig. 3) (1) framed in a frame wider than the head or a frame which lets the lenses protrude to the left and right of the frame and the head of the spectacle wearer (fig. 1b). (2) whose articulated central part is adjustable (fig. 1) (3). Equipped with branches inclined towards the inside or adjustable by a system of bending of the branches in front or at the level of the temples (fig. 2, 2b) or equipped with ordinary branches when the frame lets exceed the glasses on the left and on the right of the frame and head of the spectacle wearer (4) The device according to the invention is particularly intended for cyclists, bikers, the police, the security services or pedestrians anxious to monitor their rear.

Description

Description

Title of the invention: Rearview glasses fitted with partially one-way lenses with semi-rigid device for central adjustment of the frame by bending.

The present invention relates to a rearview mirror fitted with partially one-way glasses with central adjustment device for the frame by bending.

It is equipped with 2 optical glasses, part of the left interior surface for the left glass, and the right for the right glass is partially treated to reflect light according to the principle of two-way glass. The optics are treated in the mass or undergo a partial one-way surfacing applied to the interior part of the glass (close to the face), on the left for the left optic, on the right for the right optic.

The lenses are integrated in a frame including a flexible central system located at the central junction of the frame allows mobility of a few degrees thereof.

One-way glass separates an incident ray into two light fluxes, one reflected which makes it possible to see behind you, the other is refracted (the diffused part, of smaller quantity, being negligible). It allows you to see behind you without obstructing vision towards the front left and front right sides.

The flexible semi-rigid central system makes it possible to finely adapt the rear view to the physiognomy of the wearer.

The pair of glasses is a little wider than the head, the glasses protruding from the wearer's head on the left and right allowing good rear view.

The arms of the glasses are slightly curved inward to allow good grip on the ears.

Claims (2)

Claims [Claim 1] [Optical lenses (fiq.4) of which the part which is neither concave nor convex is partially tinted “one-way” in the mass or having undergone a one-way surfacing (soaking) on the internal part right of the right optic and left of the left optic to give it a partially one-way mirror effect. The application of the two-way mirror effect is done in a rainbow from top to bottom, (fig.3) [Claim 2] A frame which protrudes a little from the wearer's head on the left and right. Alternatively, a frame that lets the lenses protrude to the left and right of the wearer's head. [Claim 3] A central adjustment system of the frame by articulation, (fig. 1) as well as an adjustment of the temples by the same process [Claim 4] Branches inclined inwards for a good grip on the ears or adjustable by bending the branches forward or at the temples. . (Fig. 2, 2b) Alternatively, normal arms fixed on a frame which allows the lenses to protrude to the left and right of the frame and the wearer's head (fig. 1b).
