Abstract

A rear view mirror assembly including a housing and a mirror frame mounted in the housing. A pivot base sub-assembly is rotatably mounted in the housing and in mechanical communication with the mirror frame. A stored energy device is fixed to the housing and coupled to the pivot base sub-assembly. A control knob is in communication with the pivot base sub-assembly and adapted to control a scanning position of the mirror frame. The rear view mirror assembly could include a stationary base portion attached to a vehicle door and a mirror housing pivotable with respect to the stationary base portion, such that the mirror housing can be pivoted to view a desired portion of the rear view spectrum.

Claims

1. A rear view mirror assembly comprising:

a stationary base portion mounted to a vehicle;

a mirror housing including a mirror, the mirror pivotable with respect to the mirror housing and the mirror housing pivotable with respect to the stationary base portion;

a pivoting base assembly in the stationary base portion interconnected with the mirror housing,

the mirror adjustable with respect to the mirror housing to position the mirror to a proper aiming location in a normal viewing sector for normal vehicle operation, and

the pivoting base assembly pivotable about an arc to move the mirror housing and the mirror to a viewing position beyond the normal viewing sector;

a control knob in communication with the pivoting base assembly to pivot the mirror housing and the mirror about an arc beyond the normal viewing sector and to maintain the mirror housing and the mirror in a desired position along the arc; and

a stored energy device interconnected between the pivoting base assembly and the stationary base portion for automatically returning the mirror housing and the mirror to the proper aiming location.

2. The rear view mirror assembly of claim 1, wherein the stationary base portion further comprises a fixed shaft attached at one end to the stationary base portion and extending through a first aperture in the stationary base portion and a second aperture in the mirror housing.

3. The rear view mirror assembly of claim 2, further comprising a pivot shaft disposed about the fixed shaft and interconnected between the pivoting base assembly and the mirror housing.

4. The rear view mirror assembly of claim 3, further comprising a set screw for interconnecting the mirror housing to the pivot shaft.

5. The rear view mirror assembly of claim 3, further comprising a spring-biased detent screw that coacts with a dimple formed on the pivot shaft for releasably interconnecting the mirror housing to the pivot shaft.

6. The rear view mirror assembly of claim 3, further comprising a thrust bearing ring attached to one end of the pivot shaft for retaining the pivot shaft in axial relationship with the fixed shaft.

7. The rear view mirror assembly of claim 6, further comprising a thrust bearing washer positioned between the thrust bearing ring and the pivot shaft.

8. The rear view mirror assembly of claim 3, further comprising at least one lubricated bushing positioned between the fixed shaft and the pivot shaft.

9. The rear view mirror assembly of claim 3, further comprising a packing gland positioned in the first aperture of the stationary base portion and disposed annularly about the pivot shaft.

10. The rear view mirror assembly of claim 3, wherein the pivoting base assembly further comprising a set screw for engaging the pivot shaft.

11. The rear view mirror assembly of claim 3, further comprising a thrust spring positioned about the pivot shaft for damping vibrations induced by the vehicle.

12. The rear view mirror assembly of claim 1, further comprising a stop surface positioned in the stationary base portion, the stored energy device biasing an end of the pivoting base assembly against the stop surface when the pivoting base assembly is not actuated.

13. The rear view mirror assembly of claim 1, further comprising a cable interconnected between the pivoting base assembly and the control knob.

14. The rear view mirror assembly of claim 13, further comprising one or more direction-changing pulleys in communication with the cable for routing the cable from the pivoting base assembly to the control knob.

15. A rear view mirror assembly comprising:

a stationary base portion mounted to a vehicle comprising a fixed shaft attached at one end to the stationary base portion and extending through a first aperture in the stationary base portion;

a mirror housing including a mirror positioned therein, the mirror housing pivotable with respect to the stationary base portion, the mirror housing having a second aperture through which the fixed shaft extends;

a pivoting base assembly mounted in the stationary base portion and interconnected with the mirror housing;

a control knob in communication with the pivoting base assembly to pivot the mirror housing about an arc and to maintain the mirror housing in a desired position along the arc;

a stored energy device interconnected between the pivoting base assembly and the stationary base portion for automatically returning the mirror housing to a normal driving position; and

a stop surface positioned in the stationary base portion, the stored energy device biasing an end of the pivoting base assembly against the stop surface when the pivoting base assembly is not actuated.

16. The rear view mirror assembly of claim 15, further comprising a pivot shaft disposed about the fixed shaft and interconnected between the pivoting base assembly and the mirror housing.

17. The rear view mirror assembly of claim 16, further comprising a spring-biased detent screw that coacts with a dimple formed on the pivot shaft for releasably interconnecting the mirror housing to the pivot shaft.

18. The rear view mirror assembly of claim 16, further comprising a thrust bearing ring attached to one end of the pivot shaft for retaining the pivot shaft in axial relationship with the fixed shaft.

19. The rear view mirror assembly of claim 18, further comprising a thrust bearing washer positioned between the thrust bearing ring and the pivot shaft.

20. The rear view mirror assembly of claim 16, further comprising at least one lubricated bushing positioned between the fixed shaft and the pivot shaft.

21. The rear view mirror assembly of claim 16, further comprising a packing gland positioned in the first aperture of the stationary base portion and disposed annularly about the pivot shaft.

22. The rear view mirror assembly of claim 16, further comprising a thrust spring positioned about the pivot shaft for damping vibrations induced by the vehicle.

23. The rear view mirror assembly of claim 15, further comprising a cable interconnected between the pivoting base assembly and the control knob.

24. The rear view mirror assembly of claim 23, further comprising one or more direction-changing pulleys in communication with the cable for routing the cable from the pivoting base assembly to the control knob.
