DESCRIPTION

5 OBJECT OF THE INVENTION

It is an object of the present invention, as the title of the invention establishes, a splice of fire hoses, that is, refers to the connectors placed at the ends of the hoses used by firefighters in firefighting.

It characterizes the present invention the special configuration and design of the splice that is such that it prevents the hose from getting caught in different places, in addition to serving firefighters and personnel working in a fire as a means of orientation to know where The exit is found.

Therefore, the present invention is within the scope of the hoses used in firefighting and particularly the connectors of said hoses.

BACKGROUND OF THE INVENTION

So far the joints of the hose sections used in firefighting are carried out by means of Barcelona fittings which is a type 25 of coupling or fitting that in Spain is standardized under the UNE 23,400.

These fittings are couplings indicated for fire, fire and other applications, it is a symmetrical fitting, that is, any fitting connects with any other, within the same size.

It consists of a cylindrical and hollow body that has on the one hand three pins that engage with their counterparts with a quarter turn, and on the other the corresponding ligature tail, mechanized thread.

The three main diameters of said fittings are: 025, 045 and 070, 5 (Measures in mm.)

The hydraulic capacity of these fittings is fixed in norm, but as a rule they are suitable only for impulse work, not depression, as they tend to be released. The material is aluminum or brass.

These unions, although they are effective for the purpose they are looking for, present a design problem since the three protruding pins make the hoses get caught in the corners, on the edges or on the stairs, in short, anywhere Define an angled projection.

In addition, another problem encountered by firefighting personnel is that they cannot be oriented because they are generally zero visibility, not knowing where the exit may be.

Therefore, it is the object of the present invention to develop a splice that overcomes the drawbacks described by designing a splice such as the one described below and is essentially included in the first claim.

DESCRIPTION OF THE INVENTION

The object of the invention is a splice of fire hoses, where on the one hand it is achieved that there is no laterally connected connecting pin, so that it is capable of being able to be hooked on any angled projection, such as, corners, stairs etc.

To achieve this functional advantage, each fitting has a conical body such that the pins do not protrude laterally from the diameter of the base of the conical body.

On the other hand, and in order for the joint to serve as a means of guiding personnel in fires, it has visual identification means and tactile identification means.

Among the means of visual identification can be the use of colors with a certain convention, so that for example, red could be used as a danger indicator, would correspond to the start of the hose, and on the other hand, use the green color on the other fitting of the joint that would correspond to the end of the hose and that would mean where the exit is.

Among the tactile recognition means arranged on the splice, a projection, recess or bulge could be used such that it allows a tactile recognition, even if there is no visibility, having to agree on which of the fittings said tactile recognition means are arranged , which in a possible embodiment could be on the fitting that indicates the exit.

In addition, it should be borne in mind that these bushings replace the pressure flanges that are placed industrially to attach the fitting to the hose; which allows us to re-fit the hose in real time in case it suffers an injury during its use, thus recovering its function immediately.

Unless otherwise indicated, all technical and scientific elements used herein have the meaning normally understood by a person skilled in the art to which this invention pertains. In the practice of the present invention procedures and materials similar or equivalent to those described herein can be used.

Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be apparent in part of the description and part of the practice of the invention.

EXPLANATION OF THE FIGURES

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented.

In figure 1, a representation of the joint object of the invention is shown.

PREFERRED EMBODIMENT OF THE INVENTION.

In view of the figures, a preferred embodiment of the proposed invention is described below.

In Figure 1 we can see how the joint is formed by joining two conical fittings, that is, fittings that have a conical body so that the connectors do not protrude outside the conical body of the fitting.

In particular, a first fitting (1) showing a conical bushing (1.1) is shown where the connecting pins (1.2) do not protrude from the outer diameter of the conical bushing (1.1). A second fitting (2) is also shown that

It also has a conical bushing (2.1) where its connecting pins (2.2) do not protrude laterally from the conical bushing (2.1).

Figure 1 shows how when the two fittings (1) and (2) no 5 are attached, the pins (1.2) and (2.2) protrude laterally, which avoids possible hooking of the hose in its course with any angled projection, such like corners, stairs, etc.

One of the fittings, for example the first fitting (1) has a certain color, for example red indicating danger or direction to where the fire is located, while the second fitting (2) has a different color, for example green , which indicates the direction to which the exit is located.

In addition to the visual means of identification of the fittings in order to facilitate orientation in the direction of the exit, the fittings, for example, can include one of them, tactile means, which among the possible embodiments could have a recess (3), being able to count on any other construction and geometry.

20 Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is stated that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated by way of For example, and to which it will also achieve the protection sought, provided that it does not alter, change or modify its fundamental principle.
