1. A vehicular firefighting system comprising:
- a vehicle;
a boom consisting of a pair of substantially parallel tubes that form a structure for the boom and have a hollow interior that serves as a conduit for passage of a flow of a firefighting agent;
a T-shaped support coupled to the vehicle and having an internal passage for receiving the flow of a firefighting agent from a source and directing the flow to the tubes;
the T-shaped support also pivotally coupled to a first end of the tubes for movement of the tubes in a substantially vertical plane;
a junction portion pivotally coupled to a second end of the tubes, the junction portion having an internal passage for the flow of a firefighting agent from the tubes;
a nozzle coupled to the junction portion for discharging the flow of a firefighting agent; and
a linkage having a first end pivotally coupled to the nozzle and a second end pivotally coupled to the vehicle, wherein the linkage is configured to maintain an orientation of the nozzle as the boom pivots about the T-shaped support.

Abstract
A vehicular firefighting system includes a vehicle, a boom pivotally coupled to the vehicle about a horizontal axis and a nozzle pivotally coupled to the boom. In one embodiment, the system includes a linkage having a first end coupled to the nozzle and a second end coupled to the vehicle such that the linkage maintains an orientation of the nozzle as the boom pivots about the horizontal axis. In another embodiment, the boom forms at least one fluid conduit in fluid communication with the nozzle so as to deliver firefighting agent to the nozzle.

13. A firefighting agent delivery system for use with a vehicle, the system comprising:
-
a support having an internal passage for receiving a flow of a firefighting agent from a source, the support coupled to the vehicle; a boom consisting of a plurality of tubes coupled to the support;
wherein the tubes provide the structure of the boom and have a hollow interior that serves as a conduit for receiving the flow of the firefighting agent from the support and pivotally movable relative to the vehicle about a first horizontal axis and in a substantially vertical plane;a junction portion coupled to the tubes of the boom for receiving the flow of the firefighting agent from the tubes; a nozzle coupled to the junction portion for receiving the flow of the firefighting agent from the junction portion and pivotally movable about a second horizontal axis; and a linkage having a first end pivotally coupled to one of the junction portion and the nozzle and a second end pivotally coupled to the vehicle, wherein the linkage is configured to maintain an orientation of the nozzle as the tubes pivot about the first horizontal axis.

14. A method for delivering a firefighting agent from a vehicle, the method comprising:
-
pivoting a T-shaped support about a substantially vertical axis relative to the vehicle; moving a boom consisting of a plurality of substantially parallel tubes that serve as the structure for the boom and have an internal passage that serves as a conduit for a flow of a firefighting agent from the T-shaped support, the tubes coupled to the T-shaped support for pivotal movement about a horizontal axis and in a substantially vertical plane relative to the vehicle; moving the firefighting agent through a conduit formed by the T-shaped support and the tubes to the nozzle; and ejecting the firefighting agent through the nozzle. - View Dependent Claims (15)
