In order to increase the range, direction and/or control of the flow of firefighting fluid from the outlet end 16 of pipe apparatus 12, an electronically controlled fluid delivery device 30 may be mounted to the outlet end 16 of pipe apparatus 12. Exemplary electronically controlled fluid delivery devices include a nozzle or a monitor and nozzle. A monitor may increase the reach of the fluid flowing through pipe apparatus 12 and, further, provides enhanced control over the direction of flow from the outlet. Suitable nozzles and monitors are sold by Elkhart Brass Manufacturing Company, Inc. (Elkhart Brass) of Elkhart, Ind., with suitable monitors sold under the trademarks STINGER™ and SIDEWINDER® EXM available from Elkhart Brass. Exemplary electronically controlled monitors are disclosed in U.S. patent application Ser. No. 12/174,866, titled FIREFIGHTING DEVICE FEEDBACK CONTROL, the disclosure of which is expressly incorporated by reference herein.
In order to operate the power-operated actuators, such as motors 32, on the nozzle and/or monitor, power must be supplied to the actuator(s) 32 and control unit 34. However, locating a power supply at the nozzle or monitor potentially exposes the power source of the power supply to excessive heat and other detrimental environments and increases the effort to extend the pipe apparatus. Accordingly, the present invention provides a power supply system, illustratively a battery 20 that can deliver power to the monitor without subjecting the source of the power supply to the same environment as the monitor and/or nozzle and, moreover, that is accessible to the firefighter without putting the firefighter to greater risk of injury. For ease of description, the description hereafter references a monitor and nozzle application, but the invention is not so limited and also includes just the use of a nozzle or other fluid delivery devices. The illustrated battery 20 is an example of a portable power supply.
As shown in
Water source 210 provides water to pipe apparatus 12 which travels through pipe section 12A generally in direction 212. The water then travels upward in generally direction 214 and exits monitor 30 which is in fluid communication with the pipe apparatus 12 generally in direction 216 to combat a fire on floor 204B. An operator through control unit 34 may control motors 32 to adjust a nozzle of electronically controlled fluid delivery device 30 or to change an orientation of electronically controlled fluid delivery device 30 to direct the water in various directions. In one embodiment, an operator provides input signals to control unit 34 through a control input device 37. The control input device 37 may be a portable handheld device or attached to frame assembly 14. In one embodiment, the control input device 37 communicates with the control unit 34 over a wired connection. In one embodiment, the control input device 37 communicates with the control unit 34 over a wireless connection.
Referring to
As described in the referenced application, pipe apparatus 12 has a curvilinear structure, which forms inlet 24 for receiving a fluid from a source of fluid pressure, and an intermediate portion 12B, which is located between the inlet 24 and outlet 16 and which is adapted to extend from a lower floor to an upper floor. Pipe apparatus 12 is formed from a rigid material, such as a metal material, including steel, stainless steel, or aluminum or an alloy thereof, but may also be produced from a polymeric material, such as polyvinyl chloride. Pipe apparatus 12 is generally formed from several pipe sections, which are joined end to end and, further as described, includes an extendible intermediate portion that includes a telescoping portion 12C, so that the length of the pipe apparatus 12 may be increased to extend the position of outlet 16.
Referring to
As previously noted, frame 14 is adapted to support pipe apparatus 12 in a manner so that pipe apparatus 12 may be laterally guided and, further, may be pivoted to allow the outlet of the pipe apparatus to initially be extended through an opening in the wall of the building, for example through a window, and then raised so that it extends up to the floor above. As best seen in
To accommodate the extension of the pipe apparatus 12, extension arm 18 includes a fixed tubular member 18A and a telescoping tubular member 18 B, which can be fixed in position along member 18A to fix the length of intermediate pipe section 12 B by pins 44, which extend through transverse openings provided in tubular members 18A and 18 B. As previously noted, battery housing 22 is mounted to fixed tubular member 18A and further remote from outlet 16. In order to accommodate the extension of extension arm 18 (and the extension of the monitor mounted to outlet 16), the electrical cord that provides the connection between battery 20 and the monitor and nozzle motors may comprise a coiled electrical cord 44. Cord 44 may be routed through a conduit 46, which may be mounted to telescoping tubular member 18B or as noted below through extension arm 18.
Housing 22 may be fixedly mounted to tubular member 18A by a bracket 22A or may be movably mounted to tubular member 18A by a sleeve, such as a sleeve with low friction liner to allow movement of housing 22 along tubular member 18B when a sufficient force is applied. As best seen in

In the illustrated embodiment, housing 22 includes an opening 52 on one end of the housing, which includes a recess 54 that extends into the side of housing 22. Positioned below recess 54 and mounted to the exterior surface 22A of housing 22 are connectors 48. Battery 20 similarly includes surface mounted connectors 50, which align with recess 54 when inserted into housing 22 so that connectors 50 can be aligned with and guided into connection with connectors 48. Furthermore, housing 22 is sized so that when battery 20 is inserted into housing, the upper end 56 of battery 20 is substantially flush with the end of housing 22. Optionally, the battery may incorporate a handle or an engagement structure to facilitate removal of the battery from the housing. Alternately, as shown, the battery may be ejected from the housing by way of an opening 58 provided at the opposed end of the housing, such as shown in
As would be understood, by locating the battery at the proximal end of extension arm 18, the battery is located below and away from the high heat area when apparatus 10 is deployed in a firefighting situation. Furthermore, the location provides a firefighter easier access to the battery and reduces the force required to raise the pipe apparatus.
