METHOD AND DEVICE FOR HANDLING A HOSE SUPPLY

Abstract

Disclosed is a method for extinguishing a fire, comprising the following steps: a dimensionally stable hose and a reel comprising a central water connection that is rotatable relative to the reel are provided, the hose being wound on the reel; the dimensionally stable hose is designed in such a way as to have a second connection; furthermore, a transport device is provided in which the reel is rotatably mounted in order for the hose to be unwound; the hose is connected to the water supply conduit; the hose is unwound from the reel only by the length required to reach and extinguish the fire. The disclosed method dispenses with the time-consuming installing of hoses in bays and eliminates the associated risk of tripping over the hose. In the disclosed method, the wound dimensionally stable hose forms the hose supply. Moreover, the system can be filled with water and pressurized without any preparation at any time. The hose supply can remain in the bag. Also disclosed is a corresponding device, which can additionally be used as a rescue device.

[0069] FIG. 17 shows a schematic longitudinal sectional view through such a reel.

[0070] The following relates to FIGS. 1 to 6. In the case of the proposed invention a hose reel 1 with central water connection 2 is combined with a matching carry bag 3. The hose reel 1 hereby lies in the inside 4 of the bag and is mounted on a bearing device which is combined with the central water connection 2. The water connection pipe runs outwards through an opening in the bag. At its end, a dimensionally stable short hose 6 can be attached, which can be fixed externally to the bag for transport. This short hose can be used as an attack hose. At the end of the short hose there is typically attached a C or D coupling 5, as is commonly used by the fire brigade. A hose 7, which likewise is dimensionally stable, is connected to and wound on the hose reel 1 arranged in the bag 3. The inner hose 7 is 15 to 35 metres long, depending on the embodiment. The hose end is fixed at an opening 8 on the end face of the bag. The dimensionally stable hose can thus be easily released and removed from the hose reel.

[0071] The bag is made of a very robust and tear-resistant material. As shown in FIG. 7, various aids 9 can be fastened on the front side of the surface (e.g. fog nozzle, firefighter's axe, mobile smoke screen, manifold, etc.), and various sets, holsters and/or pockets can be fastened to a hook-and-loop fastener pad 10. Two hand loops 12, which can be connected to a carabiner, are fastened in each case on the front side and rear side. The carabiners can be connected individually to an endless sling 13depending on whether the bag is to be carried, dragged, hung or used as a rescue device.

[0072] It can be seen in FIG. 8 that a plastic plate 11 is attached to the rear side of the bag 3. This can form the outside of the bag 3. However, it can also be fastened on the inside 4 of the bag 3. It is also possible that the plastic plate 11 is sewn in at the rear side of the bag 3 between two material layers.

[0073] The plastic plate 11 ensures greater stability, but serves primarily as a back support for individuals lying on it, and potentially reduces the coefficient of adhesion or sliding friction as the bag is dragged along, and as applicable acts simultaneously as protection against wear.

[0074] Due to the specific arrangement of the hand loops 12 on the bag, individuals to be rescued can be quickly and easily fixed for transport. In order to perform the transport, it is expedient however to firstly remove the hose reel from the bag. An additional plastic plate 14 is then folded out to support the head. This can be seen in FIG. 9. Here, the bag is completely folded open. Once the individual has been positioned on the folded-open bag 4, this bag can be used as a stretcher. By means of the folded-out head support 14, comfortable positioning is made possible. The hand loops 12 are used as carry handles.

[0075] An alternative variant of the use of the bag as rescue device is shown in FIGS. 10 and 11: The person is positioned on the upper part 17 (with the reinforcement plate 11) of the folded-open bag. The head part 14 is likewise folded out. The lower part 18 of the bag is then guided up between the legs of the person to be rescued and placed over the legs (sandwich technique). The hand loops from the front and rear side are brought together and are connected by the carabiners. The endless sling 13, which is likewise connected to the carabiners, is used here as a pulling rope in order to pull the resultant basket stretcher from the hazard zone. For this application, the hinge region 15 of the bag is additionally reinforced.

[0076] For improved transportation of individuals, the hose reel can be easily removed from the bag. This is shown in FIGS. 12 to 15. A special quick-action fastener opening 16 with hook-and-loop fastener pads, by means of which the bag can also be opened on the side next to the connection pipe, makes it possible to remove the hose reel within a few seconds, without even disconnecting the hose line. FIGS. 12A and B show the closed bag from the outside.

[0077] In FIG. 13 the overlapping part of the upper side is being released from the hook-and-loop fastener pad 10. Further opening can be seen in FIG. 14the hook-and-loop fastener pad 10 is already exposed here. In FIG. 15 the opening process has progressed further; the bag is also open at the end face, such that the reel 1 can be removed.

[0078] An improved reel for a dimensionally stable hose can be seen in FIGS. 16 and 17. FIG. 16 shows how the preferably four struts 22 are arranged in the plane of section, specifically with equal angular distance around the central axis 20 of the reel 1. The struts organise and control the course of the coils of a dimensionally stable hose wound onto the reel. This is shown in longitudinal section through the reel 1 in FIG. 17. The struts 22 are arranged in planes that are positioned at the central axis 20 of the reel at distances corresponding to the diameter of the dimensionally stable hose 7. The hose can be wound similarly to thread on a thread spool, since it is possible to change without difficulty from one coil plane to the next in the gaps between the struts.

GLOSSARY

Attack Hose

[0079] This term denotes the hose or hose portion to which the jet nozzle is connected and from which the extinguishing agent exits during the firefighting operation.

Reel

[0080] A reel is a technical aid for winding and unwinding elongate materials, such as threads, ropes, wires and tapesin this case hoses, for which reason reference is also made to a hose reel. It has a bobbin-like structure, which is mounted rotatably about a central axis, as is the case in a cable drum for electrical cables.

Hose Supply

[0081] This term denotes a hose length (typically 15-30 m), which is additionally provided at a suitable distance from the source of fire so as to be able to advance towards the source of fire with the attack hose (see above) without great resistance.

Bag

[0082] A bag is a container for transporting objects. A bag is made primarily of flexible material and has at least one handle, loop or strap, by which the bag can be carried.
