This application is related to and claims the benefit of Italian Patent Application No. 102018000007822 filed on Aug. 3, 2018, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a connecting assembly for hydraulic-sanitary utilities with pipes for hot and cold water, respectively arranged so as to form a closed loop for the hot water and a closed loop for the cold water.
More specifically, the disclosure relates to a connecting assembly of the said type, which allows easier use and installation, as well as easier positioning, a reduction in the number of pieces, and the option of having reduced overall dimensions, consequently reducing stagnation.
It is well-known in the art how, in order to realize hydraulic-sanitary systems, a connection is needed for each hydraulic-sanitary component between the hydraulic connections of the hydraulic-sanitary component and the relative supply pipes comprising loop circuits for the hot water and for the cold water, as well as between the discharge of each hydraulic-sanitary component and the discharge pipe.
The technologies used in the '80s and '90s were characterized by lengthy execution times, by the need to have to act heavily on the wall structures and, in time, the creation of cracks at the wall interventions carried out. They are essentially loop circuits for hot water and for cold water, from which, for each utility to be served, a pipe for the cold water and a pipe for the hot water branches off.
One solution to this problem was proposed in Italian patent n° 1290251, deposited on 4 Feb. 1997, and granted on 22 Oct. 1998 in the name of Mr. Libani Roberto, and entitled “Prefabricated building module for the installation of hydraulic-sanitary components”.
The solution according to IT'251 comprises prefabricated modules, substantially made of metal material, inside which the hydraulic supply and discharge pipes are arranged, with the relative connections for the relative hydraulic-sanitary apparatus.
This solution solves many of the specific problems of the prior art, however, it is still complicated to put in place, being characterized by the presence of numerous components, as well as the impossibility of realizing the positioning as a function of the specific solution to which it is to be applied and, above all, the impossibility to reduce the overall dimensions.
In the light of the above, the Applicant has realized and perfected a connecting assembly, which can be used in the production of hydraulic-sanitary systems, which overcome the aforesaid problems.
The present disclosure will now be described, by way of a non-limiting illustrative example, according to preferred embodiments thereof, with particular reference to the figures of the attached drawings wherein:
First, it should be pointed out how the embodiments, which will be described below, must only be understood as illustrative. Also the specific dimensions must not be used in any way to limit, in any way, the protective scope of the disclosure, the features of each embodiment being able to be combined with those of others, and being independent of the measurements of the connecting assembly.
Initially observing
The connecting assembly 1 is a single block realized with any technology available, for example by 3D printing, traditional molding of any type, etc.
In the connecting assembly 1 a chamber 2 is provided for hot water and a chamber 3 is provided for cold water.
The hot water chamber 2 comprises an inlet 4′ and an outlet 4″ (which can be inverted with respect to the order shown in the figure, depending on the needs), provided with coupling systems, which do not constitute part of the present disclosure, and a single top fitting 4′″ for the connection with a hydraulic connection (not shown) of the hot water of the specific hydraulic-sanitary element (also not shown).
The chamber 2, through the inlet 4′ and the outlet 4″, is connected, in series, to the pipes of the loop circuit for hot water.
The inlet 4′ and the outlet 4″ are mutually arranged side by side along the same side as the connecting assembly 1, i.e. with the axis parallel to each other, and all lying in a single plane of connection to the loop circuit.
The top fitting 4′″ has an axis orthogonal to the plane of connection to the loop circuit.
Similarly, the cold water chamber 3 comprises an inlet 5′ and an outlet 5″ (which can be inverted with respect to the order shown in the figure, depending on the needs), provided with coupling systems, which do not constitute part of the present disclosure, and a single top fitting 5′″ for the connection to a hydraulic connection (not shown) of the cold water of the specific hydraulic-sanitary element (also not shown).
Similarly, the chamber 3, through the inlet 5′ and the outlet 5″, is connected, in series, to the pipes of the loop circuit for the cold water.
The inlet 5′ and the outlet 5″ are mutually arranged side by side along the same side as the connecting assembly 1, i.e. with the axis parallel to each other, and all lying in a single plane of connection to the loop circuit.
The top fitting 5′ has an axis orthogonal to the plane of connection to the loop circuit.
Preferably, all of the inlets 4′, 5′ and all of the outlets 4″, 5″ are mutually arranged side by side along the same side as the connecting assembly 1, i.e. with the axis parallel to each other, and all lying in a single plane of connection to the loop circuit.
Furthermore, preferably, the fittings 4′ and 5′″ for supplying hot and cold water to the hydraulic-sanitary element, both arranged with the axis orthogonal to the plane of connection to the loop circuit, are preferably placed on the same face as the connecting assembly 1.
A thread 6 is further provided on connecting assembly 1 to attach the collar supporting the discharge fitting.
Finally, the isolation chamber, realized between the hot water chamber 2 and the cold water chamber 3, is indicated with numerical reference 7.

In
Also for this embodiment, the identical or similar elements with respect to the embodiment described with reference to
As for the third embodiment, the two chambers 2, 3 are, indeed, present as chambers 32 for hot water and 33 for cold water, but they are configured, again in the connecting assembly 31, as pipes 32, 33 respectively.
The two chambers 32, 33 are joined by at least one fastening element 36, in the embodiment shown two fastening elements, which are stably constrained to the two pipes 32, 33 close to the ends.
In this case, the substantial difference with respect to the embodiment of
Advantageously, the alternation on the connection plane of the terminal ends of the two chambers 32, 33 allows a reduction in the wheelbase, making the connecting assembly significantly more compact.
In order to allow such alternation on the connection plane of the terminal ends of the two chambers 32, 33, in the fourth embodiment of the connecting assembly 31 according to the disclosure, the chambers are partially mutually overlapping on the plane orthogonal to the connection plane, while maintaining an isolation space 37.
Also in the case of the embodiment shown in
The relative elements for coupling to the hot and cold water pipes and to the hydraulic connection of the specific hydraulic-sanitary element are shown close to the inlets 34′, 34″, 35′, 35″ and the fittings 34″, 35′″.
The connections of the various embodiments of the connecting assembly 1, 11, 21, 31 according to the disclosure can be formed by any type of coupling, for example, of the threaded, crimped, quick coupling type, by welding, etc.

The present disclosure has been described by way of a non-limiting illustrative example according to preferred embodiments thereof, however, it is understood that variations and/or modifications may be made by the persons skilled in the art, without thereby departing from the relative scope of protection.
