r~LELD OF THE i~tVENTIQN
This invention reIat~ to shielding devices for external rearview mirrors mounted on vehicles. The shielding device of this invention is suitable for use with rearview mirrors for S various vehicles including cars, buses, ~n.icks and boats. Although the invcnrion will be described with reference to its particular application on a motor vehicle and more partie;ularly a motor car it should be appreciated that it is applicable to any vehicle lia ing an external rearview mirror positioned adjacent a window.
IO BACKGROUND ART
During incfemeat weather it is often very difficult for the driver of a vehicle such as a motor car to have a clear view of the externally mounted rearvision mirror.
This is a consequence of the water or even snow that will necessarily accumulate on the outer surface 15 of the vehicle window and upon the surface of the mirror itself. Dust can also accumulate on these surfaces especially if the surfaces are damp due to light rain or dew. These environmental contaminants can degrade the driver's vision of the imaga provided by the mirror to such an extent that the trurror is of little or no value. External rearview mirrors are, of course, very important to the safe operation of the vehicle especially when charging lanes, 20 reversing and parking the vehicle.
Prior art attempts at overcoming this problem have been directed to providing a shroud, such as disclosed in U.S. Paten No. 4,750,824, to protect the surface of the mirror andlor arrangements a;o direct an air tlnw onto the mirror s.irfxce. While these approaches 25 provide Borne imp:ovement they only provide partial protection to the mirror and do not fully enclose the mirror or provide a complete solution to the problem of environmental contamination by rain or spew, which rnay still contact will: the outside surface of the mirror.

BEST MODE FOR CARRYING OUT THE INVENTION
The drawings show a shielding device 10 for a vehicle external rearview mirror 11 mounted adjacent a side window (not shown) of a vehicle. The device comprises a generally rectangular transparent housing 12 which sealingly encloses the surface 13 of mirror 11. A mounting plate or side wall 14 is secured to the vehicle by means of screws 15 extending into an appropriate part of the vehicle trim (not shown}. The mounting plate extends along the window and includes a rectangular opening 16 defined by a surrounding rectangular portion 17. A seal (not shown) is provided between the rectangular portion 17 and the surface of the vehicle window so as to prevent the ingress of any environments! contaminants.
CA o 2 2 8 7 4 8 0 19 9 9 - i o - i 4 SUBSTITUTE SHEET (RULE 28) _. ~ _~_._~ ___.. ~ _~. ____ ~
The seal is of a suitably soft and resilient material such as silicon rubber that will conform to the shape of the gap and provide a substantially moisture impervious ' seal. It will be apparent that a seal of this type allows the window to be wound up and down in the usual manner. The lower edge of rectangular portion 17 rests against a ledge provided adjacent the vehicle window. The housing 12 is hingedly connected to mounting plate 14 by hinge 18 respectively secured to the plate and housing 12. This hinge may be optional, if the user does not require the device or housing to be moved forward. The housing 12 comprises an upper surface 19 a lower surface 20 connected by a rear surface 21, outer side wall a front wall 23, an outer side protruding portion 24 and a side wall extension 25.
When the device 10 is in the use position shown in Figure 1 the housing 12 and mounting plate 14 sealingly enclose the mirror surface 13. The top sheet 19 and bottom sheet 20 extend past the rear surface 21 so as to enclose that surface.
The bottom sheet 20 does not extend as far rearwardly as the top sheet 19.
Similarly, the outer side wall 22 extends past the rear surface 21 and has an inturned edge 26.
A locking tab 27 is used to retain the housing 12 in the use position by engaging a crack (not shown) between the vehicle window and the door panel. Therefore, it can also be made at half the thickness of the side wall 14 for easy insertion or otherwise it will need to bend to the proper shape for inserting into the crack. For the same function, it 27 can be replaced by some clips also.
The hinged connection of the housing 12 with plate 14 allows the housing to be swung forward in the manner shown in Figure 2 to allow access to the mirror 11 for cleaning and adjustment.
Protruding portion 24 of housing 12 is provided to fit around mirror 11 and also provide protection of outer side wall 22 from to the air flow generated as a consequence of the movement of the vehicle.
In use, the protected position of arcuate rear surface 21 prevents the CA 02287480 1999-io-i4 SUBSTITUTE SHEET (RULE 26) accumulation of environmental contaminants such as dust, water or even snow from adhering to the rear surface. The rectangular opening 16 provides a substantially unobstructed view of the mirror surface 13 from within the vehicle.
Since the rear surface 2I is not obstructed, a substantially unobstructed field of view to the rear of the vehicle is observed from within the vehicle. The protruding portion 24 of the housing I2 also prevents the accumulation of environmental contaminants along the outer side wall 22 and side wall extension 25. This provides a substantially unobstructed field of view from the mirror to the side of the vehicle.
It will accordingly be apparent that the shielding device of this invention allows a driver to see to the rear and the side of the vehicle in an improved manner even during quite inclement weather. The sealed nature of the device prevents contamination of the mirror surface or of the portion of the window through which the mirror surface is viewed whilst the exterior design of the device prevents the accumulation of contaminants on surfaces providing at least some field of view to the rear and side of the vehicle.
A further embodiment which is more aerodynamic and streamlined is shown in Figures 3 to 5. This is generally similar to that shown in Figures 1 and 2 and like reference numerals are used to denote like parts. A significant difference, however, is that protrubrance 25 is dispensed with and in its place the front wall 23 is instead formed in a convexly curved configuration, as shown clearly in Figure 4. The side walls are also angled inwardly from the top sheet 19 to the bottom sheet 20. Angling the outer side wall provides protection from rain and the like to maximise visibility through the housing whilst the inner wall is angled to match the angle of the car window, which is usually at about 20° or more with respect to the vertical. A rib protrusion 22A extends along the outer edge of the tope sheet 19, adjacent the outer side wall to further protect the side wall from snow or rain run-off from the top sheet. To further assist the aerodynamic CA o 2 2 8 7 4 8 0 19 9 9 - i o - i 4 SUBSTITUTE SHEET (RULE 26) properties of the housing, and facilitate water and snow run-off, the top of the housing is sloped downwardly Loward the front wall 23, as illustrated in Figure 5, while the rear end thereof tapers inwardly.
The front wall 23 preferably has a concave i~er profile shaped to acxommodate at least a portion of the mirror 11 to provide a seal therearound.
The wall may, therefore, be substantially rigid or flexible and provided with means to adhere it to the mirror.
A further feature of the embodiment of Figures 3 to 5 is a side wall extension or lip 26 which is provided adjacent the open end 2$ to deflect air-flow away from the opening and inhibit ingress of snow or rain which may otherwise be caused through forward motion of the vehicle.
It will be readily apparent that the shielding device according to this invention can be formed so as to be fitted to a vehicle as an after-market item.
Alternatively, it caa be manufactured with a mirror included for fitting to new vehicles in lieu of the standard external mirror.
It will also be apparent that the shielding device can be formed in any suitable shape that is capable of enclosing the external mirror and abutting the appropriate portion of the side window whilst presenting a generally streamlined profile to the air flow generated by movement of the vehicle.
The foregoing describes only one embodiment of the invention and modifications can be made without departing from the scope of the invention.
