    DESCRIPTION
    Double pipe connection system.
    Object of the invention
    5 The object of the present invention is a double pipe connection system that facilitates both the installation of plumbing during the construction of a building and its possible repairs.
    Field of application of the invention
    This invention is generally applicable in the technical field of 10 double pipe systems for plumbing and / or heating.
    State of the art
    As is known, the classic method of channeling water through walls or floors for plumbing and / or heating, consists of embedding the pipes in rubbish or regattas that are subsequently covered with a plaster layer, leaving the embedded pipes. In case of walls made of laminated plasterboard, commonly known by the Pladur brand, there are supports that are attached to the uprights of Pladur's own walls, and in them the pipes are fastened.
    The terminal elbows connecting to the faucet or radiators are fixed to the wall by the plaster in case of the classic walls. In the case of Pladur, about 20 elbows with specific screws are necessary to attach to the mentioned supports.
    A few years ago, a pipeline installation system was disclosed, consisting of using two sectional tubes and features such that one can be introduced inside the other, the interior being the one that effectively conducts water. The outer tube is embedded in the wall and the inner tube is removable. This allows to inspect and repair water leaks without the need for works, which entail higher expenses and repair deadlines. The procedure is based on removing the damaged inner pipe and replacing it completely with a new one, without breaking the expensive ceramic tiles, also difficult to repair and which, almost always, have to be replaced. To

    instead, it offers the advantage of installing a pipe implicitly protected against possible mishaps in reforms. These systems are mainly used in plumbing installations even though they are also suitable for heating or air conditioning installations in general. Utility model ES-1019319 discloses this idea.
    Some companies sell accessories and pipes for this type of double pipe systems, such as the company TIEMME RACCORDERIE SpA. These accessories are based on a 105 ° elbow connected to the inner pipe and a plastic protector where the elbow is housed, and with an open channel on its side that connects to the external pipe, as shown in Figure 1. In this embodiment, the elbow needs to have a washer attached so that it is fixed to the protector, so that the elbow It cannot be a standard accessory distributed by manufacturers other than the protector. On the other hand, the elbow does not have any component that covers the pipeline to prevent the entry of debris or make the bricklayer aware of this risk. In addition, the protector has an invariable thickness, so it is difficult to flush the guard against the wall, since the wall covering should not always have the same thickness.
    Description of the invention
    The present invention consists of a double pipe connection system that at least partially overcomes the above-mentioned drawbacks, while also being economical and easy to install.
    The double pipe connection system is provided with one or more connection assemblies consisting of a box with an open channel in its side wall, an external pipe connected to said open channel, an internal pipe of a diameter smaller than the first pipe and which can move through it, and an elbow connected to the internal pipe and located inside the box, but easily removable next to the second pipe for replacement.
    One of the inventive aspects of the present double pipe connection system is that the box contains a removable cover. In this way, the external pipe and the box can be installed without the risk of rubble entering them during masonry work that could damage the subsequent insertion of the internal pipe. In this way, it

    It grants greater freedom of operation to both the mason and the plumber who will perform the plumbing installation. . This cover optionally has a hole where a fitting can be placed, which will serve as a connection between the elbow of the inner pipe and the outside of the box. To prevent debris from entering through said hole, it has a removable plug.
    When the plug is removed and the fitting is placed in the hole, one thread of the fitting is screwed into the elbow inside the box and the other thread is on the other side of the lid, that is, outside the box. The hole of the cover is of a diameter slightly larger than the diameter of the central part of the fitting where it is located, so that the cover and the fitting can rotate relative to each other around the longitudinal axis of the fitting. On the other hand, the diameter of said hole is smaller than the diameter of at least one section of the fitting inside the box, so that the same cover would prevent the fitting from moving out of the box. Alternatively, the fitting may have another section outside the case with a diameter greater than the hole in the lid, so that the fitting would also be prevented from moving into the case. In an alternative embodiment, the fitting does not contain this last section, but it is a nut / hexagonal threaded to the fitting which fixes the cover. Several fittings available in the market have these double-threaded configurations with one or more sections of diameters larger than the threads themselves. With this system, therefore, it is not necessary to use exclusive fittings or elbows with specific geometries, which provides comfort and freedom of acquisition of the system components to their installers.
    Another inventive aspect of the present system is that the aforementioned plug fits into the end of the outer fitting to the box, so that the entry of remains of work in the pipes during masonry work once the inner pipe and the elbow coupled to the fitting. Preferably, this plug fits into holes made in the lid of the box, so that it is stored next to it once the installation is finished, being available for future repairs of the pipes and preventing them from being lost. The fact that this plug is always visible allows the bricklayer to be more easily reminded that it is appropriate to cover the pipes so that no work remains enter.
    Another different aspect of the present invention is that the case lid has one or more openings where the user can insert the fingers or a tool and thus
    5

    hold the elbow or the fitting, according to your convenience, to tighten properly when being screwed between them or to other elements of the water installation. This aspect facilitates and ensures the screwing of the components. Alternatively, the system may have a placket that serves to cover the openings of the lid in case it is of interest to avoid the entry of remains of work into the box. Preferably and in the same way as the aforementioned cover, this placket can rotate with respect to the longitudinal axis of the fitting to be removed from the openings and allow access to the interior of the box. These aspects, together with the aspects mentioned in the previous paragraph, allow the external pipe of the system to be installed before the masonry work of a room, without the need to complete the installation of water, that is, to install the internal pipe and their respective connections. This fact transfers greater freedom of operation to the mason and the plumber to manage his work without needing to depend on the work of the other.
    Another inventive aspect of the present system is that the box contains at least one hole in its rear surface where it can be fixed to Pladur walls, and at least two skewers around the hole that allow the wall to be marked to facilitate the location of the drilling site .
    Another aspect of the invention consists in having a fixing element that allows two boxes to be fixed together, thus ensuring their correct relative placement between them, that is, at the same wall depth and spaced exactly to the position of the connections of standard faucet. This aspect makes it possible to use more than one set of double-pipe housing so that the two fittings are at the correct distance so that the connection to the faucet does not require eccentric connectors, which are expensive to adjust and protrude in excess of the wall, taking up space. It also allows the placement of each set at a different angle.
    Another of the inventive aspects of this system is that the walls of the box contain grooves that allow said walls to be easily cut and, therefore, to be adjusted to the final thickness of the wall and flush to the head. This aspect allows the trim that covers the box to have a reduced thickness, giving a visually more pleasant appearance to the water installation while saving occupied space. This trim may, optionally, have an internal thread for its attachment to the fitting, or alternatively, means that fit the hexagonal or the fitting tightly and prevent rotation between them, with the intention of facilitating connection and

    disconnection of the faucet to the system. You can also have an O-ring on its outer perimeter so that its contact area with the wall is sealed.
    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
    - Figure 1 shows a pipe connection system that is part of the state of the art.
    - Figure 2 shows a perspective view of an embodiment example of the double pipe connection system according to the invention, with an exploded of the first connection set and a semi-exploded of the second connection set.
    - Figure 3 shows a sectional view of the symmetry plane of a connection assembly, according to the previous embodiment example.
    Preferred embodiment of the invention.
    In the exemplary embodiment shown in the figures, the system comprises a first assembly (C1) and a second connection assembly (C2), each consisting of a box (1) with an open channel (11) in one of its side walls, an outer pipe (21) connected to said open channel (11), an inner pipe (22) of a diameter smaller than the first pipe (21) and which can move through it, an elbow (3) connected to the second pipe (22) and located inside the box (1), and a removable cover (5) that closes the box (1).
    In this preferred embodiment, the cover (5) of the housing is crossed by a fitting (4), so that a thread (41) of the fitting (4) is inside the housing (1) screwed to the elbow (3), and the other thread (42) is on the other side of the cover (5), that is, outside the case (1).
    The cover (5) and the fitting (4) are loosely coupled, so that they can rotate relative to each other around the longitudinal axis of the fitting (4), but at the same time the hole (51) is smaller than
    5

    diameter of the section (43) adjacent to the inner thread (41) of the fitting (4), whereby the cover (5) prevents the fitting (4) from moving longitudinally out of the housing (1).
    In this configuration, a hexagonal (7) is screwed into the outer thread (42) of the fitting (4) and prevents it from moving longitudinally into the case (1).
    This preferred embodiment contains a plug (10) which serves to cover both the hole (51) of the cover (5) and the external thread (42) of the fitting (4), and fits into holes (52) of the cover ( 5) where it can be stored as long as it is not used as a plug.
    To facilitate the screwing of the elbow (3) to the fitting (4), or of the fitting to elements external to the housing (1), the cover (5) has two openings (53) on two sides where the user can see the inside of the box or insert a tool to hold the elbow (3) or the fitting (4).
    To prevent the entry of debris into the box through said openings (53), this embodiment contains a placket (6) that covers the openings (53), preferably of transparent and flexible material, which can rotate with respect to the longitudinal axis of the fitting for be removed from the openings and allow access to the inside of the box.
    A fixing element (9) with anchoring elements (91) to the box (1), allows two connection assemblies (C1, C2) to be fixed together, thus ensuring their correct relative placement between them and with the possibility of placing each set (C1, C2) at a different angle.
    Several holes (14) are practiced on the back surface of the box (1), useful in case you want to fix it to the wall with screws, and include skewers (15) around which allow to mark the position of the holes (14) on Pladur walls.
    In order to be able to adjust the thickness of the box (1) to the final thickness of the wall of the room and make it flush with head, the side walls (12) of the box (1) contain slots (13) that allow its walls (12) to be more easily cut-out and therefore adjustable in length.
    To cover the components of the connection assembly (C1, C2) after finishing the masonry work, a bezel (8) is placed through the external thread (42) of the fitting (4). In this preferred embodiment, the bezel (8) has a thread (81) in its
    inner perimeter and an o-ring (82) on its outer perimeter so that its area of contact with the wall of the room is sealed.
    Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply alteration of the essential features of the invention that are claimed below.
