Description

Field of the invention

The invention relates to a method for handling a hose reserve when extinguishing a fire, more precisely a flat or storey fire or another not directly accessible from a fire truck or other water source from fire, and a device for safe and orderly tracking the hose reserve (hose management) the fire fighting.

State of the art

The laying of hose assemblies in firefighting operations and, above all, the formation of hose reserves in buildings is often very difficult dar. There are many different methods and procedures to form hose lines and reserves before flats, but these are usually associated with a greater amount of time, which in turn often leads to compromises in hose management. The right hose management is decisive for fast and safe operation success.

So far, the laying of hose lines by means of roller hoses or hose carts. When laying the hose lines through roller hoses, the hoses must first be rolled out of the building, connected with each other and then laid by hand to the event location. The hose reserve must also be manually formed at the event location in order to be able to penetrate into the smoky danger zone.

The situation is similar when laying the hose line by means of hose carrier baskets. Although the laying of the hose to the event location designed much easier than the rolling hoses, since the hose after coupling to a fixed point (eg distributor) and carrying away the Schlauchtragekorbes quasi even from the Unrolls and moves hose carrier. Arriving at the event site, however, the tube for the formation of tube reserves must first be taken out of the hose carrier basket by hand and laid professionally. Due to the design of the hose carrier basket, the support frame is very unstable when pulling out the hose, whereby the simultaneous removal and laying of the hose by a person is difficult to implement.

As an alternative to tubular baskets, a number of devices are known in which hoses wound on a reel can be unwound while being carried by the reel. Examples of this are in the documents AT 36548 . DE 867 954 and US 3,722,823 to find. The disadvantage here is especially that the hoses must be completely unrolled before the actual use. The hose reserve must still be formed manually.

In all these variants, the laying of the hose is depressurized, d. H. the hose is not yet filled with water. If the hoses are then filled with water and put under pressure, the hose often bends around - this may result in knots in the hose reserve or, in the worst case, a fire fighter being injured. To counteract this, the water supply is usually only hesitant and careful, resulting in precious time is lost.

However, before it is finally possible to proceed into the fire apartment, the hose reserve must be checked a second time because of the pressure surges and possibly corrected. If the hose reserve is not laid correctly, retightening of the hose line is only partially possible, if at all possible, due to the high degree of friction.

Furthermore, it often happens that hose couplings wedged by design due to edges, which makes retightening the hose also impossible. This means for the preceding squad that firefighting or in the worst case, the search for people must be stopped. The troop must first go back to release the hose coupling, so that the hose can be tightened again.

In addition, the hose reserve, the z. Personnel or firefighters who have to pass through the smoky area, do not take the hose reserve true, which can lead to injuries (inter alia, by falls).

EP 0 397 461 A1 discloses a device for handling a tube reserve, comprising a reel and a hose, wherein the device is provided for wall mounting.

US 3,942,636 A and JP 2013 039380 A disclose a bag in which a tube can be transported folded flat.

task

The object of the invention is to provide a method and a device which improve the fire fighting, in particular the hose management.

solution

This object is solved by the subject matters of the independent claims. Advantageous developments of the subjects of the independent claims are characterized in the subclaims. The wording of all claims is hereby incorporated by reference into the content of this specification.

In the following, individual process steps are described in more detail. The steps do not necessarily have to be performed in the order given, and the method to be described may also have other steps not mentioned.

To achieve the object, a method for handling a hose reserve when extinguishing a fire is proposed in which initially a water supply line laid using at least one hose or provided by a fire truck. Typically, a main supply line is first laid from the hydrant or the fire truck, which ends in a distributor. There, another supply line is connected, which extends to the event floor or until shortly before the fire. Usually hoses are used for these lines, which are not dimensionally stable. For more accessible fires can alternatively be applied directly to the fire truck.

For the proposed method, the following steps are now carried out: A preferably dimensionally stable tube is provided, as well as a reel, which has a central water connection, which is rotatable relative to the reel and ensures a fluid connection to the tube which is wound on the reel , The hose is designed such that it has a second connection at its end not connected to the central water connection. Furthermore, a transport device for the reel is provided, wherein the transport device is a pocket whose surface consists of more than 50% of flexible material, and which has a hole for the central water connection. The reel is rotatably mounted for unwinding of the hose in the transport device. The transport device is fixed in the region of the end of the water supply line, for example on a railing in a staircase. The water supply line is connected to the central water connection of the reel (eg via a short hose). The hose is unwound as attack hose only as far from the reel, as it is necessary to achieve the fire, and finally the fire is extinguished. The wound part of the attack hose here forms the hose reserve.

With this method, no additional hose reserve must be formed, which eliminates the time-consuming laying of hose lines in bays and the resulting tripping hazards. The self-contained system also prevents hose couplings from becoming wedged or stuck to edges. In addition, the system can be filled with water at any time and without preparation and put under pressure. The hose reserve can in this case remain in the transport device. Also pressure surges do not affect the hose reserve and it is always a node-free tracking ensured the hose. The advantage here is in addition that the advancing firefighter must carry very little weight with it.

In a variant of the proposed method, the water supply line is connected to the second terminal of the dimensionally stable tube. Furthermore, an attack hose is connected to the central water connection of the reel. For example, a short hose, which is mounted on the outside and connected to the central water connection of the reel, serves as an attack hose. This may optionally be dimensionally stable or not, the dimensionally stable embodiment is preferred, and is between 1 and 3 m, preferably between 1.5 and 2.5 m, more preferably 2 m long. The length of the attack hose is chosen such that it can be handled by a person, and that the risk that the attack hose kinks or knots, is very low. This attack hose is led to the fire, wherein the transport device is carried along with the reel with the dimensionally stable hose. The dimensionally stable hose is unwound from the reel as far as necessary to reach the fire. This procedure allows a particularly good handling and control of the attack hose and the hose reserve.

Preferably, the hose is dimensionally stable. As a transport means a bag is provided which has a shape adapted to the shape of the reel whose surface consists of more than 50% of flexible material and which has at least one handle and / or belt on which it can be worn.

With appropriate design of the bag, this method has the additional advantage that the bag can be used as a rescue device when needed.

To solve the problem also contributes to a reel for receiving a dimensionally stable hose, which has at least two flat struts which extend from the axis of the reel to the outside. These struts are arranged in at least one plane perpendicular to the axis of the reel. This plane in turn is positioned along the axis of the reel such that a hose diameter fits between the plane and the adjacent end of the reel. If several such levels are present, they also have the distance of a hose diameter to the adjacent level. Preferably, three or four struts are arranged in each plane, the number of levels depending on the length of the reel (in tube diameters).

With such a reel is achieved that the hose at any time - regardless of whether he is filled and under pressure or not - can roll easily from the reel. Pressure surges when filling the hose do not lead to individual windings solve, unwind or hook. Rather, the hose is guided during unwinding through the struts and always remains completely under control.

The object is further achieved by a device for safe and orderly tracking of the hose reserve during firefighting, with a hose and a reel. The reel has a central water connection, which is rotatable relative to the reel and ensures a fluid connection to the hose, which can be wound on the reel. The device also has a bag for transporting the reel, wherein the surface of the bag consists of more than 50% of flexible material and the bag has at least one handle and / or belt on which it can be carried or mitgeschleift. The reel is rotatably mounted in the pocket for unwinding the hose.

In the exercise or use case, the bag can be immediately brought to the intended place (eg on the landing before a fire apartment) and connected there immediately.

In this device, a dimensionally stable tube is preferred. Then the entire system can always be filled directly with water and put under pressure due to the dimensionally stable hoses.

It is particularly favorable in this context if the reel is configured as described above.

It is also beneficial if the central water connection complies with a standard and the hose has a second connection at its end not connected to the central water connection, which corresponds to the same standard as the central water connection. In this case, it is particularly preferred if the connections are firefighting C or D couplings.

Advantageously, the internal connection of the hose with the central water connection is also standardized, preferably a C or D coupling.

In another embodiment, shut-off devices may be connected or installed to the respective couplings (outside the central water connection and / or at the end of the hose and / or at the inner end of the central water connection), which are designed as a valve, slide, flap or tap.
The bag is particularly easy to design and handle, as it has a hole for the central water connection.

The tube reserve has an optimal length when the wound tube has a length of between 15 and 45 m, preferably between 25 and 35 m, particularly preferably 30 m.

The transport of the device is additionally facilitated if the reel consists of a light metal and / or a plastic, whereby their weight is as low as possible.

In a preferred embodiment of the device, a dimensionally stable short hose is connected to the central water connection. This is between 1 and 3 m, preferably between 1.5 and 2.5 m, more preferably 2 m long and can be used as an attack hose.

If the central water connection firmly connected to the bag, the reel is secured against unwanted falling out.

For everyday use in the fire department, it is also advantageous if on the outside of the bag at least one mounting option for accessories is available. Typically, these are provided with Velcro straps.

A very useful accessory is a distributor. This makes it possible to proceed on the event floor with multiple attack lines. The water supply line is connected to the distributor. At one of the outlets of the distributor, the short hose is connected, which is connected to the central water connection. While the device is in use, another line may be connected to the splitter and made ready for use, for example, for a second squad or the security squad.

According to the invention, the pocket has a shape adapted to the shape of the reel, that is, it is essentially a flat cylinder. This facilitates the unwinding of the reel inside the bag. In addition, the bag is equipped with a front and a back and has a circumferential Velcro or zipper between the front and back. This can be easily opened to unroll the tube, or even fully opened to unfold the bag and remove the reel or use.

The circumferential closure between the front and back of the bag may have a safeguard against unintentional opening. This may be e.g. to trade a carabiner hook.

To save an unconscious person quickly from the danger area, there are numerous possibilities. Since it is not possible to search the premises quickly with a large number of rescue equipment or aids (eg grinder carrier), these must be requested during the operation. Thus, the rescue of people is limited in most cases to the very power-consuming pulling by hand or by means of endless loop. Especially when overcoming height differences or rescuing accidental respirator wearers, the physical limits are quickly reached.

The in the publication JP 2013-039380 A The disclosed device makes it possible to use a hose carrying bag, which is to be used analogously to a hose carrier basket, as a rescue device after removal of the hoses. For this purpose, two such bags can be combined with two carrying rods to form a stretcher. This approach is relatively cumbersome and necessarily requires a second person, so that the advantage over the request of an additional rescue device (whichever type) in practice should be rather low.

It would be much easier if the proposed bag would be used as a rescue device. The bag can be used as a rescue device, if there are a sufficient number of carrying handles and / or straps to transport an unconscious person in the unfolded bag can.

For the use of the bag as a rescue device, it is advantageous if the front and / or the back of the bag is reinforced with a plate. The plate increases stability and can serve as a back protector for the person to be transported. Preferably, this is a plastic plate.

If the reinforcing plate on the side facing away from the pocket skids and / or rollers, this makes it much easier to carry the bag, especially if the tube has already been filled with water.

If the reinforcing plate is designed to be removable, greater flexibility results when used as a rescue device, in particular if the plate has attachment possibilities for a person to be rescued. This may, for example, be a rescue cloth or rescue slings. The attachment of the plate to the bag is typically realized by large Velcro surfaces.

In addition, it is advantageous if a fold-out head plate is attached to the reinforcing plate, which particularly supports and protects the head of the person to be transported. This is especially important when the unfolded bag is to be used like a stretcher.

It is also advantageous if a connection area between the front and the back of the bag is reinforced as a joint. Such a designed bag can be used in particular as a life diaper.

To facilitate the use of the bag as a rescue device, on the side of the bag on which the central water supply of the reel is arranged, a hook and loop fastener may be present to allow a quick opening of the bag and removing the reel, even without the possibly to disconnect the connected hose.

The orientation of the users in very poor visibility conditions (e.g., due to heavy smoke in confined spaces) can be facilitated by attaching to the bag a safety line provided with means for automatic reeling.

A further relief in poor visibility results when lighting is provided on the front side and / or the inside of the bag. The lighting on the inside is particularly advantageous for the use of the bag as a rescue device.

The effort and labor in the use of the proposed device is reduced when the bag is provided with means for automatically winding the reel.

The following refers to the FIGS. 1 to 6 , In the proposed invention, a hose reel 1 with central water connection 2 is combined with a matching carrying bag 3. The hose reel 1 lies inside the pocket 4 and is mounted on a bearing device which is combined with the central water connection 2. The water connection pipe runs through an opening in the bag to the outside. At the end of a dimensionally stable short tube 6 may be attached, which can be fixed lying outside on the bag for transport. This can be used as an attack hose use. At the end of the short tube typically a Feuerwehrgebrauchlichen C or D coupling 5 is attached. On the lying in the bag 3 hose reel 1 is also a dimensionally stable hose 7 is connected and wound up. The inner hose 7 is 15 to 35 meters long, depending on the version. The hose end is fixed to an opening 8 on the front side of the bag. Thus, the rigid hose can be easily loosened and removed from the hose reel.

The bag is made of a very robust and tear-resistant material. On the front of the surface can, as in Fig. 7 shown, various auxiliary equipment 9 (eg hollow jet pipe, fire fighting text, mobile smoke curtain, distributor, etc.) and on a Velcro 10 various sets, holsters and / or bags are attached. On the front and back are two hand loops 12, which can be connected to a carabiner. The carabiners can be individually connected to an endless loop 13 - depending on whether the bag is worn, tightened, hung or used as a rescue device.

In Fig. 8 It can be seen that at the back of the bag 3, a plastic plate 11 is attached. This can form the outside of the bag 3. But it can also be attached to the inside 4 of the bag 3. It is also possible that the plastic plate 11 is sewn to the back of the bag 3 between two layers of fabric.
The plastic plate 11 provides more stability, but mainly serves as a back protection for people lying on it, possibly reduces the adhesive or sliding friction when tightening the bag and possibly acts at the same time as protection against wear.

Due to the special arrangement of the hand loops 12 on the bag can be quickly and easily fix people to be rescued for transport. However, to carry out the transport, it makes sense to first remove the hose reel from the bag. An additional plastic plate 14 to support the head is then unfolded. This is in Fig. 9 to see. Here is the bag completely unfolded. After positioning the person on the unfolded bag 4, this can be used as a carrier. By folded out headrest 14 comfortable positioning is possible. The hand straps 12 serve as carrying handles.

In 10 and 11 an alternative variant of the use of the bag is shown as a rescue device: The person is positioned on the upper part 17 (with the reinforcing plate 11) of the unfolded bag. The head part 14 is also unfolded. Subsequently, the lower part 18 of the bag between the legs of the person to be rescued is guided upwards and over this (sandwich technique). The hand loops from the front and back are brought together and connected to the carabiners. The endless loop 13, which is also connected to the carabiners, serves as a pull rope to pull the resulting abrasive wearer from the danger area. For this application, the hinge portion 15 of the bag is additionally reinforced.

To better carry people, the hose reel can be easily removed from the bag. This is in the FIGS. 12 to 15 shown. By a special Quick-release opening 16 with Velcro surfaces, through which the bag can also be opened on the side next to the connection pipe, it is possible to remove the hose reel in a few seconds even without uncoupling the hose line. Figs. 12A and B show the closed bag from the outside.

In Fig. 13 the overlapping part of the upper side is released from the Velcro surface 10. The further opening is in Fig. 14 to see - the Velcro 10 is already here free. In Fig. 15 the opening process is even more advanced, the bag also opens at the front, so that the reel 1 can be removed.

An improved reel for a dimensionally stable hose is in FIGS. 16 and 17 to see. Fig. 16 shows how the preferably four struts 22 are arranged in the cutting plane, namely at the same angular distance around the central axis 20 of the reel 1 around. The struts arrange and control the course of the windings of a coiled on the reel, dimensionally stable hose. This is in longitudinal section through the reel 1 in Fig. 17 shown. The struts 22 are arranged in planes, which are positioned at intervals corresponding to the diameter of the dimensionally stable tube 7, on the central axis 20 of the reel. The tube can be wound like yarn on a spool of thread, since in the spaces between the struts can be easily changed from one winding plane to the next.
