Abstract

Automotive lighting systems include a casing which defines an interior space and a pair of shafts extending thereacross so as to establish adjacent first and second interior space regions. Lamps are positioned in respective ones of these adjacent first and second interior space regions and are covered by a respective pair of lenses. Each lens has proximal and distal ends and is connected pivotally at the proximal end thereof to a respective one of the shafts to allow for independent pivotal movements of the distal end between inoperative and operative positions. Push switches are operatively connected to respective ones of the lamps and positioned in respective ones of the first and second interior space regions in such a manner that the distal ends of each lens is in contact with a respective push switch. In such a manner, the push switches may be operated in response to the pivotal movements of the lenses between its inoperative and operative positions to thereby illuminate the lamps. Most preferably, the pair of shafts are positioned closely adjacent one another and extend across the casing at generally a central position thereof such that the proximal ends of the lenses are immediately adjacent one another with the lenses extending in opposite directions toward the distal ends thereof. The automotive lighting systems may be provided as a component part of a door switch circuit which responsively operates the lamps on opening of an automotive door.

An automotive lighting system comprising:

a casing which defines adjacent first and second interior space regions;
a pair of lamps positioned in respective ones of said adjacent first and second interior space regions;
first and second lenses covering respective ones of said adjacent first and second interior space regions, each of said first and second lenses having proximal and distal ends, and being positioned relative to one another so that said proximal ends thereof are adjacent to one another generally at a central region of said casing and said distal ends thereof are positioned remotely from one another near respective lateral regions of said casing,
mounting assemblies for respectively mounting each one of said first and second lenses to said casing for independent operable movements with respect to the other of said first and second lenses, wherein said each of said mounting assemblies include;
(1) opposed pairs of fulcrum shafts projecting from respective opposed sides of said casing near said central region thereof,
(2) pairs of bearing sections formed at said proximal ends of said first and second lenses for engagement with a respective one of said pairs of fulcrum shafts to allow for pivotal movements thereabout;
(3) opposed pairs of fixed shafts spaced from said fulcrum shafts and projecting from said opposed sides of said casing near said distal ends of said first and second lenses;
and
(4) pairs of engagement sections each having hooks for engagement with respective ones of said fixed shafts so as to allow said distal ends of said first and second lenses to be moved towards and away from said casing in response to pivotal movements of said proximal ends thereof about said fulcrum shafts;
and wherein said system further comprises,
a pair of push switches operatively connected to said respective ones of said lamps and positioned in respective ones of said first and second regions of said interior space such that each of said distal ends of said first and second lenses is in contact with a respective one of said push switches so as to allow said respective one of said push switches to be operated in response to a respective one of said distal ends of said first and second lenses being moved towards said casing when pivoted about said fulcrum shafts to thereby illuminate said lamp operatively connected thereto.
