Abstract
A system for signalling conditions of, including an emergency within, a vehicle comprises a main housing mountable on the vehicle at a location visible from substantially all lateral points. A warning light is mounted within the housing and light which it generates is projected from the housing by an optical system as a plurality of substantially collimated beams each of which is oblique with respect to the major axis of the vehicle. A switch for actuating the warning light is located within the vehicle for unobtrusive operation. The system also includes additional signal lights for signalling different conditions of the vehicle and circuitry which prevents simultaneous operation of certain of the signal lights that have contradictory meanings.
Claims27
A system for signalling an emergency within a vehicle, comprising:
- a main housing mountable on the vehicle at a location visible laterally from all points about the vehicle;
- warning light producing means mounted within said main housing for producing warning light;
- optical means for causing the warning light produced by said warning light producing means to be projected from said housing as a plurality of beams each of which is oblique with respect to the major axis of the vehicle, said optical means comprising a plurality of elongate tubular members mounted on said main housing each having an axis extending obliquely with respect to the major axis of the vehicle when said main housing is mounted thereon and through each of which the warning light produced by said warning light producing means is projected as one of the beams;
- and
- means for actuating said warning light producing means unobtrusively from within the vehicle.
A system for signalling an emergency within a vehicle, comprising:
- a main housing mountable on the roof of said vehicle to be visible laterally from all points about said vehicle;
- warning light producing means mounted within said main housing for producing warning light;
- a plurality of elongate tubular members each mounted on said main housing and having an axis extending obliquely with respect to the major axis of said vehicle;
- a plurality of collimator lenses each mounted between said light producing means and an end of one of said tubular members remote from said light producing means, said collimator lenses and said tubular members collimating light from said light producing means in a plurality of beams each projecting obliquely with respect to said major axis;
- and
- means for actuating said light producing means unobtrusively from within the vehicle.
A signal light system for a taxicab, said system comprising:
- a housing mountable on said taxicab and including a portion laterally visible 360 degrees about said taxicab when mounted thereon;
- a plurality of signal light producing means mounted within said housing and including a first signal light producing means for selectably indicating that said taxicab is available for hire, and a second signal light producing means for selectably indicating that said taxicab is off duty;
- means for preventing simultaneous activation of said first and said second light producing means;
- warning light producing means mounted within said portion of said housing for producing warning light;
- optical means for projecting light produced by said warning light producing means as a plurality of beams each of which is oblique with respect to the major axis of the taxicab, said optical means comprising a plurality of elongate tubular members each mounted on said portion of said housing and each having an axis extending obliquely with respect to said major axis when said housing is mounted on said taxicab, the warning light produced by said warning light producing means being projected through each of said tubular members as one of said beams;
- and
- means for actuating said warning light producing means unobtrusively from within said taxicab.
