Definitions

  • the present invention relates to a mobile air supply cart. More specifically, the present invention is directed to a cart for transporting cylinders that contain a supply of air for personnel using breathable gas and water fire hoses while working in a smoke filled, toxic, or another hazardous environment.
  • a hose is that identified by U.S. Patent Number 6,520,178, which discloses two air hoses located within a water hose, together with a system allowing for easy connect and disconnect of the air supply to the firefighter’s mask that could be used with a standard self-contained breathing apparatus used by firefighters.
  • Patent Number 6,520,178 is disclosed in pending application PCT/US2019/016501 , which, among other things, discloses a system for an air and water hose apparatus that automatically switches the user’s source of air from the apparatus to tanks worn on the back of the user when the air pressure in the apparatus falls below a certain pressure.
  • Patent Number 6,521 ,178 (“Air and Water Hose Apparatus for Firefighters”), which applications are incorporated herein by reference, the wearer is not required to be solely reliant on the limited amount of air that can be provided by such cylinders on his back, because breathable air is supplied through the hose apparatus.
  • air must be supplied to the breathable air and water hose apparatus.
  • Stand-alone pressurized air cylinders such as those used in self-contained breathing apparatuses, may be used as such a remote source of air to supply such a hose.
  • such cylinders are heavy and bulky, and transporting them to facilitate movement of the user is difficult and time consuming. Even when the hose is lengthy, this presents a serious drawback in those situations in which the user must move rapidly, a frequent occurrence when fighting fires.
  • This object, as well as other objects, is accomplished in a mobile gas supply cart having a support for at least one, and more preferably three, compressed gas cylinders. At least two wheels are rotatably coupled to the support and a piping assembly is supported on the support.
  • the piping system has (i) a manifold supported by the support and having inlet ports for receiving gas from the compressed gas cylinders and an outlet port, (ii) a pressure regulator in flow communication with the manifold port, and (iii) at least one outlet port for supplying gas to a breathable gas and water hose.
  • the support has (i) a base portion to which the wheels are coupled, (ii) a frame portion for supporting compressed gas cylinders, (iii) a connector for coupling and uncoupling the frame portion from the base portion, and (iv) storing capacity for a folded, empty breathable gas and water hose that is not in use.
  • Figure 1 is a front elevation view of the mobile air supply cart according to the current invention.
  • Figure 2A is a rear elevation view of the mobile air supply cart according to the current invention.
  • Figure 2B is an enlarged view of one end of a breathable gas and water hose apparatus that may be used in conjunction with the current invention.
  • Figure 3 is an enlarged partial view of the cylinders and piping system.
  • Figure 4 is a rear elevation view of the mobile air supply cart including a cover protecting a folded, empty breathable gas and water hose.
  • Figure 5 is an interior view of the mobile air supply cart according to the current invention with the surrounding environment illustrated by dotted lines.
  • the mobile air supply cart 101 according to the current invention is shown in Figure 1.

  • the breathable gas and water hose 102 may be one such as that disclosed in pending application PCT/US2019/016501 , filed on February 4, 2019 in the name of 1005, LLC and titled “Breathable Gas and Water Hose Apparatus”.
  • the cart 101 is comprised of a frame assembly base 103.
  • the base 103 has a handle 104 which is affixed at one end and a bottom tray 105 which is affixed at the other end.
  • a pair of wheels 106 are mounted on the base 103.
  • the base 103 has a wall support 107 extending upwardly from the tray 105 attached thereto.
  • the tray 105 is adapted to support three compressed air cylinders 110, 111 and 112.
  • the cylinders 110, 111 and 112 are secured to the base 103 or the wall support 107.
  • the base 103 can also be configured to support a folded breathable gas and water hose 102 as shown in Figure 2.
  • a piping system 120 is mounted on the cart 101 , as shown in Figure 5.
  • the piping system 120 regulates the flow of breathing air from the compressed air cylinders 110, 111 and 112 to the regulator 121.
  • Each of the compressed air cylinders 110, 111 and 112 has a first shut-off valve 124 at its top, as shown in Figure 3 and in Figure 5.
  • a piping system 120 shown in Figure 5, features a coupling for each cylinder 110, 111 and 112 that is adapted to mate with the outlets of the corresponding shut-off valves 124.
  • High pressure hoses 113, 114 and 115 direct the compressed air from the cylinders 110, 111 and 112 to a four-way manifold 126. From the four way manifold 126, the air flows to a regulator 121.
  • a gauge as is well known in the art, allows the pressure of the air in the regulator 121 to be monitored.
  • a safety valve also well known in the art, connected to the regulator 121 ensures that the air pressure does not exceed a predetermined value.
  • the regulator 121 is connected to a quick connect fitting, well known in the art, that allows a breathable gas and water hose 102 to be connected.
