Abstract

A small, wide angle mirror, for application upon a conventional vehicle side view mirror surface, formed of a molded plastic, generally wedge-shaped, box having integral walls and a curved base which is mirrored. The box is closed with a separate, flat plate which is frictionally secured within the box and is spaced a short distance inwardly of the free edges of the box walls. A resilient pad is adhesively secured to the exposed surface of the plate and is partially concealed within the box and partially extends outwardly of the plane of the free edges of the walls. A pressure sensitive adhesive coating upon the pad secures the pad to the vehicle side view mirror surface for thereby fastening the mirror attachment in place.

Claims

1. A wide angle mirror for attachment upon a vehicle side view mirror, comprising:

a thin wall, hollow, closed base and open top, plastic molded box formed of walls and a base which are integral to provide a unitary body, and a separate cover for application to the body to cover the open top thereof;

the free edges of the walls all being in a common plane, and elongated ledges formed upon the interior surfaces of the walls at a distance inwardly, i.e., towards the base, from said box edges and being parallel to said box edges;

said cover being formed of a thin plate normally fitted within said walls and engaged with said ledges;

and flanges formed upon the interior surfaces of said walls closely adjacent the plane of the free edges of the walls and spaced from their adjacent ledge portions a distance about equal to the plate thickness so that the plate is frictionally gripped between the ledges and flanges for thereby interlocking the plate within the box;

and said box walls being sufficiently resiliently flexible to flex the flanges apart so that the plate may be manually forced between opposing flanges and into contact with the ledges and thereafter the flange will close over the adjacent edge portion of the plate for thereby assembling the plate to the box body;

and an adhesive coating applied upon the exposed face of the plate, so that the plate may be applied against and adhesively fastened to the mirror surface of a side view mirror for thereby fastening the box thereto;

and the external surface of at least the base being reflective, and the base being curved so that said external face forms a wide angle reflective surface.

2. A device as defined in claim 1, and said adhesive coating being formed upon a resilient pad, which is adhesively secured to the exposed surface of the plate, whereby said resilient pad is interposed between the plate and the side view mirror surface.

3. A device as defined in claim 2, and said plate being depressed inwardly of the box, that is, towards the base thereof, so that its exposed surface is inwardly relative to the plane of the box wall free edges;

and said pad being of sufficient thickness to extend outwardly of the plane of the wall free edges a short distance, so that a substantial portion of the pad is concealed within the box.

4. A device as defined in claim 3, and said box being formed in a generally rectangular shape with two opposed, elongated side walls and two opposed end walls, with all the walls being integral with each other and the base;

and with one of the end walls being considerably deeper than the other, with said base being curved between said end walls so that the box appears to be generally wedge-shaped in its lengthwise direction;

and with said ledge being formed by thinning the edge portion of the two elongated side walls and the deeper end wall to form a substantially continuous shoulder extending parallel to the free edges of the walls along said three walls, and with the line of intersection between the base and the less deep end wall being in planar alignment with said shoulder to form a continuation thereof along the less deep wall;

and said flanges formed of elongated portions, integral with the two side walls and located between the ledge forming shoulders and the free edges of their repsective walls, so that the plate is thereby held inwardly of the plane of the free edges of the walls.
