The present invention relates to a hose deployment device and in particular to a device to rapidly and reliably deploy a lay flat expanding hose in a linear or coiled fashion.
Hoses are used throughout the world to transport fluid between different locations. For example, industrial hoses are typically used between various machines and in process plants. Hoses are also used around swimming pools, gardens and by fire fighters and other emergency personnel to extinguish fires.
Fire fighters and emergency personnel will often carry their own hoses to a location where a fire is to be extinguished. A fire hose is very easy to manipulate while dry. As soon as water is introduced into the hose, it expands and becomes harder, more strenuous and time consuming to maneuver and direct the resultant water stream. To be effective the hose must allow the water to flow at the optimum flow rate. To this end a hose should not be pressurized with water until it is correctly laid out. It takes a fire fighter a considerable amount of time to correctly deploy a hose in a confined space i.e. fire stairs and terrace style courtyards or the like. The extra time causes significant delays in extinguishing fixes and rescuing people.
Typically, three factors contribute to the correct deployment of a fire hose, Firstly, hose preparation or how a hose is folded is critically important as quick and accurate deployment is required. A fire fighter needs to avoid kinking and needs lineal space usually at least a minimum of 15 meters to deploy the hose. Secondly, hose deployment or the functionality of the hose is important as it effects the nature of the water travelling through the hose. Lastly, the hose lay or the nature the hose is made ready is important as the hose needs to be laid straight out along a surface and organized and this can be particularly difficult to achieve when fighting a fire at night or in heavy smoke as something as simple as a car tyre can interrupt the unrolling hose. Also, a fire fighter or other emergency personnel often wear protective equipment making correct hose deployment challenging.
Common to all events where hose lay is required; there are two standard needs that must be met. The first being a need to ‘stretch’ a hose from a pressurised water supply to a point at or near to the entry of a fire where it can then be connected to the second standard hose lay. A hose ready to deploy into a room, compartment or area involved in the fire. There is a need for a device that stores and deploys, ‘stretches’ or ‘Lays’ a hose from the pressurised water supply to a point at or near to the entry point of a file or incident.
In an attempt to address the above problems some fire fighters use a High Rise or Remote Access Kit to convey hose to a hydrant in a point too far from the fire truck. However, the High Rise or Remote Access Kit is simply a typical backpack that is large enough to hold the equipment required and does not assist the fire fighter in the correct deployment of a hose. When rolling out a hose a linear space of 15 meters is required. When deploying a hose from a hydrant in a stairwell of a high rise building the hose needs to be rolled down the stairs to achieve the 15 meters. This adds significant weight for the fire fighter to move when the hose is pressurized with water.
In U.S. Pat. No. 6,267,319 is shown an apparatus and method of rolling a fire hose. However, this device rolls the hose in a coil about a large fixed metal structure. It is not in a pack, bag or other easily portable device. The structure is also heavy, requires considerable storage space and still requires manual handling of deployed and undeployed fire hose.
Accordingly, there is a need for a device to assist a fire fighter or other emergency personnel to easily and quickly prepare, deploy and lay a fire hose or the like in a confined space. In particular, to reliably deploy a hose with no kinks or tangles while increasing the speed of water exiting the hose, while decreasing the physical exertion of the fire fighter or other emergency personnel.
It is an object of the present invention to substantially overcome or at least ameliorate one or more of the disadvantages of the prior art, or to at least provide a useful alternative.
