Abstract
Abstract A lamp assembly for a road vehicle including a mounting plate which in use extends transversely of the vehicle. The mounting plate carries a pair of lamp units which are mounted adjacent one another on the mounting plate, so as to be at the left-hand side or the right-hand side of the front of the vehicle. A wiper arm is carried on a linkage arrangement supported by the mounting plate, and the wiper arm extends forwardly of the vehicle between the two lamp units. At its outer end the wiper arm is provided with a pair of wiper blades which extend in opposite directions one of the blades engaging the lens of one of the lamp units while the other blade engages the lens of the other lamp unit. A drive motor drives the linkage arrangement, and the linkage arrangement is such that the wiper arm moves in such a path that the wiper blades wipe the front surfaces of the lenses of the two lamp units. A second pair of lamp units can be mounted on the mounting plate at the opposite side of the vehicle, and the same drive mechanism can drive a second wiper arrangement associated with the other pair of lamps units. In addition, the wiping systems can incorporate means for supplying washing fluid to the lenses of the lamps during wiping.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A lamp assembly, for a road vehicle, including a mounting plate which in use extends transversely of a road vehicle, a pair of light units each of which has a curved lens, means mounting said light units adjacent to one another on said mounting plate in such a manner that in use said light units will be at oneside or the other of the vehicle, a wiper arm, said wiper arm extending between said light units, a pair of wipers, means mounting said pair of wipers at one end of said wiper arm so that said wipers extend in opposite directions from said wiper arm and are engageable with the lenses of said light units respectively, and, a drive linkage for reciprocating said wiper arm in a plane passing between said light units, said linkage being coupled to said wiper arm, and causing movement of said wipers in an arc of radius of curvature substantially equal to the radius of curvature of said light unit lenses, the wiper arm itself being shorter than said radius of curvature.
Claim 2
Dependent Claim
177 words
A lamp assembly, for a road vehicle, including a mounting plate which in use extends transversely of a road vehicle, a pair of light units each of which has a curved lens, means mounting said light units adjacent to one another on said mounting plate in such a manner that in use said light units will be at oneside or the other of the vehicle, a wiper arm, said wiper arm extending between said light units, a pair of wipers, means mounting said pair of wipers at one end of said wiper arm so that said wipers extend in opposite directions from said wiper arm and are engageable with the lenses of said light units respectively, and, a drive linkage for reciprocating said wiper arm in a plane passing between said light units, said linkage being coupled to said wiper arm, and causing movement of said wipers in an arc of radius of curvature substantially equal to the radius of curvature of said light unit lenses, the wiper arm itself being shorter than said radius of curvature.
Claim 3
Dependent Claim
24 words
An assembly as claimed in claim 1 wherein said linkage is driven by a shaft which is reciprocated about its longitudinal axis in use.
Claim 4
Dependent Claim
44 words
An assembly as claimed in claim 2 wherein said shaft similarly drives a second wiper arm associated with a pair of light units mounted in use on the side of the front of the vehicle remote from the first mentioned pair of light units.
Claim 5
Dependent Claim
22 words
An assembly as claimed in claim 1, further including a system for supplying washing liquid to the lenses of the light units.
Claim 6
Dependent Claim
41 words
An assembly as claimed in claim 4 wherein the wiper arm is hollow and carries a pair of jets through which washing fluid is directed onto said lenses, as jets communicating with a reservoir of washing liquid through the wiper arm.
Claim 7
Dependent Claim
178 words
A lamp assembly, for a road vehicle, including a mounting plate which in use extends transversely of a vehicle, a pair of light units each of which has a curved lens, means mounting said light units adjacent one another on said mounting plate in such a manner that in use said light units will be at one side or the other side of the vehicle, a wiper arm, said wiper arm extending between said light units, a pair of wipers, means mounting said pair of wipers on one end of said wiper arm, so that said wipers extend in opposite directions from said wiper arm and are engageable with said lenses of said light units respectively, means for reciprocating said arm in a plane passing between said light units so that said wipers wipe the lenses of said light units respectively, there being a rest position which said wipers assume when inoperative, and, a decorative member associated with said mounting plate, said decorative member being arranged to mask the wipers when the wipers are in said rest position.
Claim 8
Dependent Claim
178 words
A lamp assembly, for a road vehicle, including a mounting plate which in use extends transversely of a vehicle, a pair of light units each of which has a curved lens, means mounting said light units adjacent one another on said mounting plate in such a manner that in use said light units will be at one side or the other side of the vehicle, a wiper arm, said wiper arm extending between said light units, a pair of wipers, means mounting said pair of wipers on one end of said wiper arm, so that said wipers extend in opposite directions from said wiper arm and are engageable with said lenses of said light units respectively, means for reciprocating said arm in a plane passing between said light units so that said wipers wipe the lenses of said light units respectively, there being a rest position which said wipers assume when inoperative, and, a decorative member associated with said mounting plate, said decorative member being arranged to mask the wipers when the wipers are in said rest position.
