Abstract

A rear view mirror head for vehicles, especially automotive vehicles such as small trucks, comprises a mirror head body constituted by a unitary, resilient dish-shaped molding of a tough, weather-resistant organic polymer composition, preferably an ABS resin, which presents about its front side peripheral formations for supporting a reflecting mirror plate with an edge gasket of the plate adhered thereto and comprises a backwardly hollowed narrow ear-shaped portion the hollow of which opens to the front side of the molding and has fitted into it rigid ear-reinforcing arms of angled brackets of which rigid base portions extend over and are fixed to areas of the front side adjacent to the hollowed portion of the molding. The resin of the molding can be of an electroplatable type having a stiffening decorative metal coating plated onto at least the outside surfaces. The construction obviates unsightly corrosion and difficulties of mirror plate mounting experienced with previous mirror heads of similar type, while providing the required strength and security of mounting of the mirror head in viewing position on a vehicle.

Claims

1. In a rear view mirror for vehicles, including a dish-shaped body of sheet-like material presenting about its front side peripheral formations to support a reflecting mirror plate and having thereon a backwardly protruding ear member clampable to a support arm for holding the mirror in viewing position on a vehicle, the improvement wherein said body is a unitary, resilient dish-shaped molding of a tough, weather-resistant organic polymer composition and said ear member is constituted by a backwardly protruded hollowed portion of said molding the hollow of which is closed at the backward end of said portion and opens to the front side of said molding and has fitted thereinto a rigid ear-reinforcing means which comprises at least one angled rigid metal bracket, each said bracket having an arm portion thereof extending inside said hollow and having a base portion thereof extending over and seated against an area of said front side adjacent to said hollowed portion.

2. A rear view mirror according to claim 1, said molding comprising integral reinforcing ribs protruding forwardly from said front side and extending therealong, each rib transverse to another, in the regions of the molding inside said peripheral formations and about the area occupied by said reinforcing means.

3. A rear view mirror according to claim 1 or 2, said molding being composed essentially of an acrylonitrile-butadiene-styrene resin.

4. A rear view mirror according to claim 1 or 2, said body being a molding of an electroplatable acrylonitrile-butadiene-styrene resin having a stiffening and decorative metal coating plated onto at least its outside surfaces.

5. A rear view mirror according to claim 4, said coating being formed of successive plated layers respectively of nickel, copper, nickel, and chromium.

6. A rear view mirror according to claim 1 or 2, said reinforcing means comprising a pair of said angled rigid metal brackets the respective arm portions of which bear back to back against each other and are fitted into said hollow and the respective base portions of which extend oppositely over and are fixed to respective areas of said front side at opposite sides of said hollowed portion.

7. A rear view mirror according to claim 1 or 2, said backwardly protruding portion and each said arm portion being formed with an opening extending laterally therethrough, and said openings being aligned to receive through said ear member an end portion of a support arm for mounting the mirror for use.

8. A rear view mirror for vehicles, comprising a unitary, resilient dish-shaped sheet-like molding composed of a tough weather-resistant resin, said molding presenting about its front side peripheral rim surfaces for supporting a reflecting mirror plate with a gasket about the edge of the plate adhered to said surfaces by adhesive, said molding comprising a central, integral, backwardly protruding hollow narrow portion thereof forming an ear member and the hollow of which is closed at the backward end of said portion and opens to said front side and has fitted thereinto a rigid ear-reinforcing means which comprises at least one rigid angled metal bracket having an arm portion thereof extending inside said hollow and having a base portion thereof extending at an angle to said arm portion over and fixed to an area of said front side adjacent to said backwardly protruding portion, whereby said ear member is clampable and will be held secure on a support arm for holding the mirror in viewing postition on a vehicle.

9. A rear view mirror according to claim 8, said molding comprising integral reinforcing ribs protruding forwardly at said front side and extending therealong one transverse to another in the regions of said molding about the area occupied by said base portion.

10. A rear view mirror according to claim 8, said reinforcing means comprising a pair of said rigid angled metal brackets the respective arm portions of which bear back to back against each other and are fitted into said hollow and the respective base portions of which extend oppositely over and are fixed to respective areas of said front side at opposite sides of said backwardly protruded portion.

11. A rear view mirror according to claim 8 or 10, said molding being composed of electroplatable resin and having plated onto at least its outside surfaces a decorative metal coating formed of successively applied platings respectively of nickel, copper, nickel, and chromium.

12. A rear view mirror according to claim 8 or 10, said backwardly protruding portion of said molding and said arm portion of each said bracket having an opening extending laterally therethrough and said openings being aligned to receive through them an end portion of a said support arm.
