Abstract

A single shell side-view mirror assembly is disclosed which provides improved aerodynamic features and improved vibrational resistance characterized by an aerodynamically domed shell structure, interchangeable mirror elements, an electrically activated vibration dampening element and a static vibration dampening elements.

Claims

1. A vehicular side-view mirror assembly for vehicle, comprising:

a shell housing having a first end and a second end;

a mirror mounting structure for holding a plurality of mirror units;

a first mirror unit having a first side-view mirror disposed thereon, the first mirror unit being independently adjustable and locatable by means of said mirror mounting structure in either of the first and second ends of the shell housing;

a second mirror unit having a second side-view mirror disposed thereon, the second mirror unit being independently adjustable and locatable by means of said mirror mounting structure in either of the first and second ends of the shell housing;

a support member for coupling the shell housing to the vehicle;

wherein the vehicular side-view mirror assembly of the mirror mounting structure includes;

first and second mounting elements disposed in the shell housing;

wherein the first mirror unit is connected to the first mounting element and the second mirror unit is connected to the second mounting element;

wherein the first mounting element of the shell housing comprises first standoffs for operatively engaging the first mirror unit at either end of the shell housing; and

wherein the second mounting element of the shell housing comprises second standoffs for operatively engaging the second mirror unit at either end of the shell housing.

2. The vehicular side-view mirror of claim 1, wherein the first standoffs are longer than the second standoffs.

3. The vehicular side-view mirror of claim 1, wherein the shell housing has a domed cross section for providing aerodynamic characteristics which reduce vibration of the first and second mirrors and reduce torsional forces on the support member.

4. The vehicular side-view mirror of claim 1, wherein the shell housing further comprises a maintenance hole for enabling access to the interior of the shell housing when the first and second mirror units have been installed into the shell housing.

5. The vehicular side-view mirror of claim 4, wherein the maintenance hole is sealed with a removable cover plate.

6. The vehicular side-view mirror of claim 5, wherein the removable cover plate provides an external surface for displaying indicia.

7. The vehicular side-view mirror of claim 1, wherein the first side-view mirror is a flat mirror and the second side-view mirror is a convex mirror.

8. The vehicular side-view mirror of claim 1, wherein the first and second side-view mirrors are positioned in a substantially planar relationship with the edge of the shell housing.

9. The vehicular side-view mirror of claim 1, wherein the first and second mirror units comprise snap means for engageably securing the first and second mirrors respectively thereto so that field retrofitable replacement of the mirrors is obtained.

10. The vehicular side-view mirror of claim 1, wherein the first and second mirror units comprise vibration tabs which are elastically biased and engage the rear surface of the first and second mirrors to reduce vibration of the mirrors.

11. The vehicular side-view mirror of claim 1, wherein the support member comprises:

a hinge member; and

a tube member for entering and engaging the shell housing on one end and operatively connecting to the hinge member on the other end.

12. The vehicular side-view mirror of claim 11, wherein the shell housing comprises a grommet disposed in a mounting hole which engages the tube member for preventing foreign matter from entering either of the shell housing and the tube member through the mounting hole.

13. The vehicular side-view mirror of claim 11, wherein the support member further comprises a core material disposed within the tube member for strengthening the tube member and reducing the vibration of the side-view mirror assembly.

14. The vehicular side-view mirror of claim 13, wherein the tube member is formed of a first metal material and the core material is formed of a second, dissimilar metal material to dampen vibrations of the tube member.

15. The vehicular side-view mirror of claim 14, wherein the tube member is formed of steel and the core material is formed of aluminum.

16. The vehicular side-view mirror of claim 11, wherein the tube member comprises first and second supporting tube members disposed in perpendicular relation and attached thereto for operatively engaging the hinge member.

17. The vehicular side-view mirror of claim 11, wherein the hinge member comprises:

a housing member, the housing member being engageable with the support member;

a hinge plate member, the hinge plate member being operatively engageable with the housing member and having attachment elements disposed thereon for rigidly fixing the hinge plate member to the vehicle, the hinge plate member having a precision bore for accepting a precision mounting bolt therethrough, which precision mounting bolt operatively engages the housing member and fixes the hinge plate member to the housing member in swingable relation, the precision dimensions of the bore and the bolt being sufficient to reduce vibrational movement between the hinge plate member and the housing member.

18. The vehicular side-view mirror of claim 17, wherein the housing member and the hinge plate member comprise:

a multi-position detent for fixing the hinge plate member relative to the housing member in a position of use, the multi-position detent exerting a force on the hinge plate member and housing member that resists swingable movement and reduces vibrations in the hinge member when the mirror assembly is in a position of use, the multi-position detent permitting swingable movement of the hinge plate member relative to the housing member when sufficient torsional force is exerted on the hinge plate member relative to the housing member such that the hinge plate member and housing member reach a position of maximum rotation wherein the multi-position detent again exerts a force on the hinge plate member and housing member that resists swingable movement therebetween.

19. The vehicular side-view mirror of claim 1, wherein the shell housing has a width of approximately 7½

inches, a height of approximately 13 to 14 inches and a depth which tapers towards the center and, at the deepest point, measures approximately 3 to 4 inches.

20. The vehicular side-view mirror of claim 1, wherein the first mirror unit has a width of about 6 to 7 inches and a height of about 9 to 10 inches and the second mirror unit has a height of about 4 to 4½

inches and a width of about 7 inches.
