Description

DESCRIPTION

Hose coupling set

field of invention

The present invention relates to a coupling assembly for hoses, especially applicable to fire hoses used by firefighters in extinguishing fires.

Background of the invention

Currently, during firefighting, firefighters have to cut off the water supply to the hose when it is necessary to disconnect the lancehead and mount a new section of hose, on which the lancehead is remounted. .

In these situations, it is necessary to notify the fire truck operator to cut off the water supply. It is therefore necessary to wait for the drop in water pressure in the hose (whose length can be several hundred meters) to be able to carry out this operation to lengthen the hose. All this means interrupting the action of the firefighters, which entails a loss of time, which on some occasions when working to extinguish a fire can be essential.

Therefore, a coupling assembly for hoses is necessary to speed up the lengthening process of the hose.

Summary of the invention

The object of the present invention is, therefore, to provide a coupling assembly for hoses that allows speeding up the process of lengthening the hose with the addition of a new section.

The invention provides a hose coupling assembly comprising a lance with a fitting and, additionally, a ball valve, which has a hose coupling attached to one end and a hose coupling to the other end. attached a fitting configured to mate with the spearhead fitting.

By means of this configuration, a coupling assembly for hoses is achieved that allows the immediate shutdown of the hose's water supply, to allow the lance tip to be disconnected and thus mount a new section of hose on whose end the lance tip is reassembled. launches, all without having to cut off the water supply from a truck or from the source of the supply.

Another advantage of the invention is that the elements of the assembly can be quickly coupled to each other, which contributes to reducing the total assembly time of the assembly.

Another advantage of the invention is that the elements of the assembly are standard and standardized parts, so there are no replacement problems in the event of failures.

Other advantageous embodiments of the invention are set forth in the dependent claims.

Brief description of the drawings

Next, the object of the present invention will be illustrated in a non-limiting manner, with reference to the accompanying drawings, in which:

Figure 1 shows an assembly of a lance tip on the end of a hose, according to the state of the art.

Figure 2 shows an embodiment of a hose coupling assembly of the invention attached to a length of hose.

Figure 3 shows an elongated assembly with several sections of hose and with a coupling assembly for hoses of the invention at one of the ends.

Figure 4 shows another embodiment of a hose coupling assembly of the invention attached to a length of hose.

Detailed description of the invention

Figure 1 shows a lance tip attached to the end of a hose, which is the assembly commonly used by firefighters in the state of the art. Said coupling may be a quick coupling, union type.

Figure 2 shows a hose coupling assembly 1 of the invention attached to a length of hose 5. Assembly 1 comprises a lance tip 8 with a fitting, and additionally a ball valve 4. This ball valve 4 A hose coupling is attached to one end and a fitting 3 configured to engage spearhead fitting 8 is attached to the other end.

In Figure 2 the hose coupling is a hose coupling 2. According to another embodiment, shown in figure 4, the coupling for hoses is a fitting 2', which would be coupled to another fitting 9 located at the end of hose 5.

These fittings 3, 2', 9 are quick coupling elements, and are standardized in Spain within the UNE 23400 standard as connection fittings within fire-fighting material. This fitting is also called a Barcelona fitting.

According to one embodiment, the ball valve 4 is a valve with a female thread at both ends, and the coupling for hoses and the fitting 3 have a male thread at one of their ends, the male threads being attachable to the female threads of the valve. ball 4.

According to another embodiment, the ball valve 4 is a 1 inch diameter valve, and the male threads of the hose coupling and fitting 3 are also 1 inch.

Likewise, the ball valve 4 of the assembly of the invention may comprise a manual lever 7 to facilitate its opening and closing, preferably a lever of reduced length.

With assembly 1 of the invention, the process of lengthening the hose becomes faster, since once the quick coupling assembly 1 is available to hoses coupled to a hose 5, the ball valve 4 is closed by means of the manual lever 7, whereupon the water stops coming out of the lance tip 8. Then the fitting 3 is disengaged from the lance tip fitting 8, and a longer hose 5' is chosen. This hose 5' or longer section is coupled at one end to the fitting 3, and at the other end it is coupled to another coupling assembly 1 for hoses of the invention. The operator or the firefighter can then open the ball valves 4 in order to be able to extinguish the fire again.

With this hose coupling assembly 1 it is not necessary to cut off the water supply from the truck, stopping the pump, but rather the operator or firefighter himself can do it from wherever he is with the hoses 5, 5', using a minimum amount of time.

In this case, there would be pressure in the hose 5, and the maneuver of adding a section of hose would be done in about 20 seconds, instead of several minutes in which they would remain without activity and with the risk of possible exposure to fire, especially in forest fires.

In the case of the embodiment of figure 4, the coupling of the set 1 would even be immediate, since by having the fitting 9 it can be assembled or disassembled on the hose 5 without the use of tools, which would save more time.

Although some embodiments of the invention have been described and represented, it is evident that modifications within its scope can be introduced, and it should not be considered limited to said embodiments, but only to the content of the following claims.
