Abstract

Abstract A rear view mirror extension assembly that may be used in conjunction with the mirror support bracket on an automotive vehicle such as a pick-up truck, van or the like, and it is particularly useful when the vehicle is towing a travel trailer or boat to improve the field of vision for the driver of the vehicle rearwardly of the latter. The improved field of vision is desirable and increases the safety in driving a vehicle equipped with the invention on the highway, as well as permitting easier maneuvering of the vehicle drawing a trailer or boat into a recreational vehicle parking space.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 297 words
In an automotive vehicle having a bracket extending outwardly therefrom that includes an upper horizontal portion in which a transverse opening is formed through which a screw extends upwardly to engage a tapped bore extending downwardly in a post of a rear view mirror to support said mirror from said bracket, the combination with said bracket after said mirror and screw have been removed therefrom of an assembly for adjustably supporting said mirror outwardly from said vehicle a greater distance than when mounted on said bracket, said assembly including: a. an elongate rigid adaptor member that has first and second ends, and resting on said upper horizontal portion, a transverse bore adjacent said first end through which said screw extends upwardly to engage said tapped bore in said post to support said mirror from said member, and an elongate slot in said member intermediately disposed between said transverse bore and said second end; b. a bolt that includes a head, and a shank that extends downwardly therefrom through said slot to have a portion of said shank situated there-below, said portion having external threads thereon; c. a nut that engages said threads; and d. a plurality of washers that have said shank extending therethrough and that are in contact with said elongate rigid member and said bracket, with said slot permitting said rigid member and mirror to be moved longitudinally relative to said bracket to improve the field of vision visible in the mirror relative to that obtainable when the mirror is mounted on said bracket, and said elongate member and mirror being maintained in the position to which they are adjusted by tightening said nut to compress said washers and force them into frictional engagement with said head and nut and said bracket and elongate member.
Claim 2
Dependent Claim 297 words
In an automotive vehicle having a bracket extending outwardly therefrom that includes an upper horizontal portion in which a transverse opening is formed through which a screw extends upwardly to engage a tapped bore extending downwardly in a post of a rear view mirror to support said mirror from said bracket, the combination with said bracket after said mirror and screw have been removed therefrom of an assembly for adjustably supporting said mirror outwardly from said vehicle a greater distance than when mounted on said bracket, said assembly including: a. an elongate rigid adaptor member that has first and second ends, and resting on said upper horizontal portion, a transverse bore adjacent said first end through which said screw extends upwardly to engage said tapped bore in said post to support said mirror from said member, and an elongate slot in said member intermediately disposed between said transverse bore and said second end; b. a bolt that includes a head, and a shank that extends downwardly therefrom through said slot to have a portion of said shank situated there-below, said portion having external threads thereon; c. a nut that engages said threads; and d. a plurality of washers that have said shank extending therethrough and that are in contact with said elongate rigid member and said bracket, with said slot permitting said rigid member and mirror to be moved longitudinally relative to said bracket to improve the field of vision visible in the mirror relative to that obtainable when the mirror is mounted on said bracket, and said elongate member and mirror being maintained in the position to which they are adjusted by tightening said nut to compress said washers and force them into frictional engagement with said head and nut and said bracket and elongate member.
Claim 3
Dependent Claim 41 words
An assembly as defined in claim 1, in which said elongate member is a bar formed from a metal that is resistant to corrosion from the weather, with said bar being pivotally, as well as longitudinally, adjustable relative to said bracket.
Claim 4
Dependent Claim 75 words
An assembly as defined in claim 1, in which said elongate member is formed from a weather resistant sheet, said elongate member having side edges and a convex curved outer end, and said side edges and curved outer end developing into a continuous normally disposed flange that serves to reinforce said sheet from deformation due to the weight of said mirror supported therefrom, with said flange extending downwardly over said horizontal portion of said bracket.
