Abstract

A mounting plate of generally semi-circular plan shape is provided and includes one straight side edge and an opposing arcuate side edge whose opposite ends converge toward the ends of the straight side edge. The arcuate side edge of the mounting plate includes outturned flange portions which terminate outwardly in inturned flange portions and the front side of the plate includes a pair of generally parallel reinforcing flanges extending outwardly therefrom and disposed at generally right angles to the straight side edge of the mounting plate and the mounting plate. The outer marginal portions of the flanges are arcuate and curve inwardly from the ends of the flanges adjacent the straight side edge of the mounting plate toward the mounting plate adjacent the arcuate side edge of the mounting plate. A partial convex spherical mirror element of generally semi-circular plan shape is disposed in registry over the front side of the mounting plate with the arcuate edge of the mirror element received in the aforementioned upturned flange portions of the arcuate side edge of the mounting plate. In addition, the outer marginal edges of the flanges abut the back or undersurface of the mirror element for bracing the same and a cap plate is provided including a first straight longitudinal edge portion and a second outwardly convex arcuate edge portion. The cap plate is secured over the straight side edge of the mounting plate and the corresponding edge of the mirror element and includes flange portions embracingly engaging the straight side edge of the mounting plate and the corresponding edge of the mirror element.

Claims

1. A mirror construction comprising a mirror element including first and second opposite side edges, a mounting plate of a plan shape corresponding to the plan shape of said element over one side of which said element is placed in plan registry therewith, said plate including first and second opposite side edges corresponding with the first and second side edges, respectively, of said element, the first side edge of said plate being generally straight, the second side edge of said plate including opposite end portions which curve inwardly toward the remote ends of the first side edge of said plate, said second side edge end portions including retaining flange portions extending therealong, projecting outwardly of said one side of said plate and terminating outwardly in inwardly directed flange portions overlying said one side of said plate in spaced relation relative thereto, elongated reinforcing flanges supported from said one side of said mounting plate, projecting outwardly therefrom and extending between said first and second edges of said plate, said reinforcing flanges including arched outer longitudinal edges underlying, abutted by and closely conforming to the contours of the adjacent portions of the side of said mirror element opposing said one side of said mounting plate with said second side edge of said element being held captive within said retaining flange portions and beneath said inwardly directed flange portions, and a cap panel removably secured over said first side edge of said plate and the corresponding edge of said element, said cap panel including a first inturned retaining flange overlying the outer side of the first side edge of said element and a second inturned flange overlying the first side edge marginal portion of said plate on the other side thereof.

2. The combination of claim 1 including mounting means supported from said mounting plate for support of said mirror construction from a support structure.

3. The combination of claim 1 wherein said mounting means includes means mounting said plate from said mounting means for adjustable angular diplacement relative thereto about an axis generally paralleling said first side edge of said mounting plate.

4. The combination of claim 1 wherein the opposite end portions of said first inwardly directed flange include outwardly offset terminal ends overlying the corresponding ends of said inturned flange portions.

5. The combination of claim 1 wherein said cap panel is removably secured position by means of fasteners secured through said cap panel and into the adjacent ends of said reinforcing flanges.

6. The combination of claim 1 wherein said element is convex spherical in configuration.

7. The combination of claim 1 wherein said cap panel includes a third inturned flange generally paralleling and spaced inwardly of said first inturned flange underlying and supporting said first side edge of said element.
