Abstract

An emergency response vehicle such as an ambulance is provided with a warning unit that provides a visual and audible warning signal. The warning unit is mounted in a recess or cutout in the hood which covers the engine compartment of the vehicle. This positioning of the warning unit avoids blockage of the air flow through the radiator required for cooling of the vehicle engine. Brackets or other suitable devices are used to mount the warning unit, preferably to a wall such as a radiator support, so that the warning unit remains stationary during opening and closing of the hood. The wall also serves to block rearward passage of the noise generated by the warning unit.

Claims

1. An emergency response vehicle comprising:

a chassis;

an engine supported on said chassis and positioned within an engine compartment;

a radiator mounted in front of the engine;

a grill positioned forwardly of the radiator and constructed to permit an air stream to flow through the grill and to the radiator for cooling thereof;

a hood positioned in covering relation to at least a portion of the engine compartment, said hood being mounted for raising and lowering to provide access to the engine compartment;

a cutout provided at a forward position in the hood; and

a warning unit comprising a flashing light and a siren coupled with the vehicle chassis and positioned within said cutout in the hood.

2. The emergency response vehicle as set forth in claim 1, including a wall positioned forward of the engine and wherein said first warning unit is mounted on said wall.

3. The emergency response vehicle as set forth in claim 2, wherein the radiator is mounted to the wall.

4. The emergency response vehicle as set forth in claim 3, including a second cutout in the forward position of the hood and a second warning unit positioned within the second cutout, said first and second cutouts being laterally spaced apart in said hood.

5. The emergency response vehicle as set forth in claim 4, including brackets mounting the first and second warning units to said wall, said first and second warning units being adjustable on said brackets in a fore-and-aft direction.

6. The emergency response vehicle as set forth in claim 3, wherein said warning unit includes a barrier wall positioned behind a sound generating portion of the siren to block rearward propagation of said generating sound.

7. An emergency response vehicle comprising:

a chassis;

an engine supported on said chassis and positioned within an engine compartment;

a radiator mounted in front of the engine;

a grill positioned forwardly of the radiator and constructed to permit an air stream to flow through the grill and to the radiator for cooling thereof;

a hood positioned in covering relation to at least a portion of the engine compartment, said hood being mounted for raising and lowering to provide access to the engine compartment;

a first cutout provided at a forward position in the hood; and

a warning unit comprising a flashing light and a siren coupled with the chassis and positioned within said first cutout in the hood and out of said air stream, said first warning unit being mounted independently of the hood to permit raising and lowering of the hood without movement of the first warning unit.

8. The emergency response vehicle as set forth in claim 7, including a wall positioned forward of the engine and wherein said first warning unit is mounted on said wall.

9. The emergency response vehicle as set forth in claim 8, wherein the radiator is mounted to the wall.

10. The emergency response vehicle as set forth in claim 9, including a second cutout in the forward position of the hood and a second warning unit positioned within the second cutout, said first and second cutouts being laterally spaced apart in said hood.

11. The emergency response vehicle as set forth in claim 10, including brackets mounting the first and second warning units to said wall, said first and second warning units being adjustable on said brackets in a fore-and-aft direction.

12. The emergency response vehicle as set forth in claim 9, wherein said first warning unit includes a barrier wall positioned behind a sound generating portion of the siren to block rearward propagation of said generating sound.

13. An emergency response vehicle comprising:

a chassis;

an engine supported on said chassis and positioned within an engine compartment;

a wall positioned in front of the engine;

a radiator mounted to said wall in front of the engine;

a grill positioned forwardly of the radiator and constructed to permit an air stream to flow through the grill and to the radiator for cooling thereof;

a hood positioned in covering relation to at least a portion of the engine compartment, said hood being mounted for raising and lowering to provide access to the engine compartment;

a pair of spaced apart cutouts provided at a forward position in the hood; and

a pair of warning units each comprising a flashing light and a siren coupled with the chassis, one of the warning units being positioned within one of said spaced apart in the hood and the other of said warning units being positioned within the other of said spaced apart, said warning units being mounted on said wall and independently of the hood to permit raising and lowering of the hood without movement of the warning units.

14. The emergency response vehicle as set forth in claim 13, including brackets mounting the warning units to said wall, said warning units being adjustable on said brackets in a fore-and-aft direction.

15. The emergency response vehicle as set forth in claim 14, wherein said warning units each includes a barrier wall positioned behind a sound generating portion of the siren to block rearward propagation of said generating sound.
