Abstract

A backward vision device comprises a mirror (11) mounted by an arm (14) which is attached at one end to a firm joint (12) upon the rear of the mirror and at its other end to another firm joint (16) upon a clip (18) which is shaped to fit over the top of a spectacle frame (20), or the joint (14) can be attached directly to a spectacle frame. When not in use the device can be unclipped or moved to a position beside the user's head. Alternatively, the clip (18) is adapted to fit onto a cap or visor. The device enables the user to see behind without turning his head.

Description

SPECIFICATION Device for backward vision This invention relates to a device whereby a person may conveniently be able to see what is behind him without turning his head. It can be useful to jockeys or other racers, policemen, security guards orto any pedestrian who fears an attack from behind.
The device of the invention consists of a mirror jointedly mounted upon an arm which is jointed to a clip which is adapted to fit onto a spectacle frame or headgear.
In an alternative embodiment, for use by persons who do not normally wear spectacles, the device consists of a mirrorjointedly mounted e.g. on an arm which is integrallyjointedly mounted on a spectacle frame by any suitable means.
The invention is illustrated with reference to a preferred embodiment shown in the accompanying drawing, wherein Figure 1 is a perspective view of the device and Figure 2 is a plan view thereof showing it in use.
A mirror 10 in a suitable frame 11 is attached at a hinge or joint 12 to one end of an arm 14, the other end of which is attached at a joint 16 to a clip 18 which is adapted to be firmly fixed to the top of a user's spectacle frame.
In use, the device is placed as shown in full line in Figure 2, clipped to the top outer edge of the front of a spectacle frame 20, the user can thereby, merely by moving his eyes but not his head, see into the mirror and thereby have a view of what lies almost directly behind him. When not in use, the mirror can be unclipped or can be placed in the position shown in dotted line, so as to lie along the side of the user's head. A possible sightline is indicated at 22.
The joints of the device must be made firm enough so that the mirror will stay in a desired position but that the position can be adjusted as necessary to suit the user.
The clip may be lined with plastics or other resilient material to avoid damage to the frame or lenses of the spectacles.
Alternatively, in place of the clip 16 the joint 14 is attached directly to a spectacle frame containing no lenses or plain glass.
A pair of such devices may be provided, one on each side of a spectacle frame.
In a further alternative, the clip 18 may be adapted to fit onto the peak of a cap or visor worn by the user, and the arm be long enough to enable the mirror to be fixed in a position forwardly and above the user's head, to enable him to see above and behind himself.
1. A device for backward vision, which comprises a mirrorjointedly mounted on an arm which is jointedly mounted to a clip which is adapted to be fitted onto a spectacle frame or headgear.
2. A modification of a device as claimed in Claim 1, which includes a spectacle frame whereon the arm isjointedly mounted.
3. A device as claimed in Claim 1, substantially as herein before described with reference to the accompanying drawing.
