What is required is an apparatus for cleaning a mirror mounted to an exterior of a motor vehicle that is adapted for use with a substantially flat rectangular mirror.
According to the present invention there is provided apparatus for cleaning mirror mounted to exterior of motor vehicle, including an elongate tubular body having a first end, a second end, and a fluid cavity that extends between the first end and the second end. The first end is sealed. The second end has a hose coupling adaptor. A plurality of radial fluid outlets are positioned axially along tubular body between the first end and the second end. Means is provided for securing the tubular body along one edge of a mirror with the radial fluid outlets oriented toward a pane of the mirror. A source of washing liquid and a source of compressed air are provided.
A conduit provides a first path and a second path and has a coupling end, a first end and a second end. The coupling end of the conduit is connected to the hose coupling adaptor at the second end of the elongate tubular body. The first end of the conduit is connected to one of the source of washing liquid and the source of compressed air. The second end of conduit is connected to the other of the source of washing liquid and the source of compressed air. Means is provided for selectively activating the source of compressed air, alone, along one of the first path and the second path, such that fluid flows through the conduit into the fluid cavity and out the plurality of radial fluid outlets onto the pane of the mirror. Means is provided for activating the source of compressed air, in combination with the source of washing liquid along the other of the first path and the second path, such that fluid flows through the conduit into the fluid cavity and out the plurality of radial fluid outlets onto the pane of the mirror.
According to another aspect of the present invention there is provided an apparatus, as described above, in combination 21 ~7~03 with a truck mirror positioned on a motor vehicle.

DE~ATT~n DESCRIPTION OF THE ~K~rr;KKr;v EMBODIMENT
The preferred embodiment, an apparatus for cleaning a mirror mounted to an exterior of a motor vehicle generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 3.
FIGURE 1 illustrates apparatus 10 in combination with a truck mirror 12 mounted by an attachment bracket 14 to an exterior of a motor vehicle, the motor vehicle being generally represented by 18. Truck mirror 12 includes a rectangular pane 20 supported in a shallow rectangular frame 22.
Referring to FIGURE 2, apparatus 10 includes an elongate tubular body 24 having a first end 26, a second end 28.
Referring to FIGURE 3, a fluid cavity 30 extends between first end 26 and second end 28. Referring to FIGURE 2, first end 26 is sealed. Second end 28 has a male hose coupling adaptor 32.
A plurality of slotted radial fluid outlets 34 are positioned ~1 ~37603 axially along tubular body 24 between first end 26 and second end 28. Tubular body 24 has a projecting tab 36 with fastener receiving apertures 38. Referring to FIGURE 3, tubular body 24 is secured along one edge 40 of mirror 12 by fasteners 42.
Referring to FIGURE 1, when attached to mirror 12, as described, radial fluid outlets 34 are oriented toward pane 20 of mirror 12. A source of washing liquid 44 and a source of compressed air 46 are both provided within motor vehicle 18.
A conduit 48 is provided which provides two alternative paths for the flow of fluids; a first path 50 and a second path 52.
Conduit 48 has three ends; a coupling end 54, a first end 56 and a second end 58. Coupling end 54 of conduit 48 is connected to male hose coupling adaptor 32 at second end 28 of elongate tubular body 12. First end 56 of conduit 48 is connected to source of washing liquid 44. Second end 46 of conduit 48 is connected to source of compressed air 46. A
three position activation switch 60 is provided within motor vehicle 18. When activation switch 60 is in a first position source of compressed air 46 is activated, alone and fluids are diverted along first path 50 from source of compressed air 46 through to coupling end 54. When activation switch 60 is in a second position source of compressed air 46 is activated and diverted along second path 52 where it draws washing fluid from source of washing liquid 44. When activation switch 60 is in an intermediate position, source of compressed air 46 is shut off causing apparatus 10 to be inactive.
The use and operation of apparatus 10 will now be described with reference to FIGURES 1 through 3. Referring to FIGURE 1, when activation switch 60 is moved to the first position compressed air flows from source of compressed air 46, through conduit along first path 50, sending only air into fluid cavity 30. The compressed air escapes from fluid cavity 30 through radial fluid outlets 34, blowing across pane 20 of mirror 12. The force of the compressed air blows dirt and debris from pane 20 of mirror 12. When activation switch 60 is moved to the second position, compressed air flows from 21 ~7603 compressed air source 46 through conduit 48 along second path 52 drawing washing liquid from source of washing liquid 44.
Washing liquid is carried by the compressed air along conduit 48 into fluid cavity 30 and out of radial fluid outlets 34 onto pane 20 of mirror 12. When pane 20 of mirror 12 is clean, activation switch 60 is moved back to the first position so that only compressed air flows through conduit 48. As compressed air continues to blow, any residue of washing liquid is blown from pane 20 of mirror 12, thereby leaving a clean and clear viewing surface.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
