Abstract
Abstract The invention relates to a vehicle outside rear view mirror assembly of the type wherein the mirror may be rotated between a laterally extended rear viewing position and a folded back non-viewing position, and more particularly which includes a goose-neck mirror supporting arm having a vertical arm portion including first detent means formed integrally therein and which means coacts with second detent means formed in a resiliently deformable mirror arm supporting sub-assembly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
201 words
A mirror swing lock mechanism of the type including an arm (12) having a generally horizontal mirror supporting section (14) and a depending generally vertical section (18), a bracket assembly (30) for adjustably supporting said vertical arm portion to the exterior surface of a vehicle, the bracket assembly and the vertical arm section coacting to provide a mechanism for releasably retaining said arm in a plurality of positions about a generally vertical axis coaxial with the vertical arm section, the improvement in said mechanism comprising: a) the vertical arm section (18) having a portion (40) of circular cross section in the outer surface of which first detent means (54, 56) is formed; b) the bracket assembly including means (32, 34) defining a generally cylindrical surface (36, 38) adapted to receive and support the circular portion of the vertical arm section, the diameter of said arm portion (40) being larger than that of said cylindrical surface to provide an interference fit between said arm portion and said means; and c) second detent means (42, 44) formed in said cylindrical surface and coacting with the first detent means to releasably retain said arm in a plurality of rotatable positions about said vertical axis.
Claim 2
Dependent Claim
201 words
A mirror swing lock mechanism of the type including an arm (12) having a generally horizontal mirror supporting section (14) and a depending generally vertical section (18), a bracket assembly (30) for adjustably supporting said vertical arm portion to the exterior surface of a vehicle, the bracket assembly and the vertical arm section coacting to provide a mechanism for releasably retaining said arm in a plurality of positions about a generally vertical axis coaxial with the vertical arm section, the improvement in said mechanism comprising: a) the vertical arm section (18) having a portion (40) of circular cross section in the outer surface of which first detent means (54, 56) is formed; b) the bracket assembly including means (32, 34) defining a generally cylindrical surface (36, 38) adapted to receive and support the circular portion of the vertical arm section, the diameter of said arm portion (40) being larger than that of said cylindrical surface to provide an interference fit between said arm portion and said means; and c) second detent means (42, 44) formed in said cylindrical surface and coacting with the first detent means to releasably retain said arm in a plurality of rotatable positions about said vertical axis.
Claim 3
Dependent Claim
60 words
A mirror swing lock mechanism of the type set forth in claim 1 wherein at least one of said first or second detent means is formed of a material which allows said detent means to be recoverably deformable so as to permit the detent means to become disengaged as said arm (12) is rotated relative to the bracket assembly (30).
Claim 4
Dependent Claim
51 words
A mirror swing lock mechanism of the type set forth in claim 1 wherein the bracket assembly includes a pair of elements (32, 34) which coact to form the cylindrical surface (36, 38) and fastening means (50) for securing said elements together to clampingly support the vertical arm portion (40) therebetween.
Claim 5
Dependent Claim
57 words
A mirror swing lock mechanism of the type set forth in claim 1 wherein the bracket assembly comprises a plate (22) having a first surface conforming to the shape of an adjacent vehicle surface, a second surface (28) to which the bracket assembly (20) is mounted and fastening means (50) for securing said assembly to said plate.
Claim 6
Dependent Claim
29 words
A mirror swing lock mechanism of the type set forth in claim 4 wherein a cover member (66) is provided for enclosing said plate (22) and bracket assembly (30).
Claim 7
Dependent Claim
44 words
A mirror swing lock mechanism of the type set forth in claim 1 wherein the first and second detent means comprise a plurality of coacting elongated grooves (54, 56) and ribs (42, 44) disposed parallel to the vertical axis of said mirror arm (12).
Claim 8
Dependent Claim
187 words
A mirror swing lock mechanism of the type including an arm (12) having a generally horizontal mirror supporting section (14) and a depending generally vertical section (18), a bracket assembly (30) for adjustably supporting said vertical arm portion to the exterior surface of a vehicle, the bracket assembly and the vertical arm section coacting to provide a mechanism for releasably retaining said arm in a plurality of positions about a generally vertical axis coaxial with the vertical arm section, the improvement in said mechanism comprising: a) the Vertical arm section (18) having a portion (40) of circular cross section in the outer surface of which is formed a plurality of circumferentially spaced longitudinally extending grooves (54, 56); b) the bracket assembly including means (32, 34) defining a generally cylindrical surface (36, 38) adapted to receive and support the circular portion of the vertical arm section; and c) a plurality of longitudinally extending ribs (42, 44) circumferentially spaced about the cylindrical surface (36, 38) of said means and nestingly coacting with the grooves to releasably retain said arm in a plurality of rotatable positions about said vertical axis
Claim 9
Dependent Claim
187 words
A mirror swing lock mechanism of the type including an arm (12) having a generally horizontal mirror supporting section (14) and a depending generally vertical section (18), a bracket assembly (30) for adjustably supporting said vertical arm portion to the exterior surface of a vehicle, the bracket assembly and the vertical arm section coacting to provide a mechanism for releasably retaining said arm in a plurality of positions about a generally vertical axis coaxial with the vertical arm section, the improvement in said mechanism comprising: a) the Vertical arm section (18) having a portion (40) of circular cross section in the outer surface of which is formed a plurality of circumferentially spaced longitudinally extending grooves (54, 56); b) the bracket assembly including means (32, 34) defining a generally cylindrical surface (36, 38) adapted to receive and support the circular portion of the vertical arm section; and c) a plurality of longitudinally extending ribs (42, 44) circumferentially spaced about the cylindrical surface (36, 38) of said means and nestingly coacting with the grooves to releasably retain said arm in a plurality of rotatable positions about said vertical axis
Claim 10
Dependent Claim
49 words
A mirror swing lock mechanism of the type set forth in claim 7 wherein said means (32, 34) is formed of a material which allows said ribs to be displaced out of nesting engagement with said grooves as said arm (12) is rotated relative to the bracket assembly (30).
Claim 11
Dependent Claim
41 words
A mirror lock mechanism of the type set forth in claim 7 wherein at least one rib (42,44) is formed in each semi-cylindrical surface (36, 38) and projects radially inwardly therefrom to nestingly engage a proximately disposed arm groove (54, 56).
Claim 12
Dependent Claim
70 words
A mirror swing lock mechanism of the type set forth in claim 9 wherein each member (32, 34) includes a thin wall section (62, 64) from which each rib (42, 44) projects, each thin wall section permitting its rib to be deflected radially outwardly from its semi-cylindrical surface and thereby move out of nesting engagement with an arm groove (54, 56) when the arm is rotated about its vertical axis.
