Abstract

- The invention relates to a connection system (1) between an air network for the ventilation of a building, and a socket tile (2), comprising a sleeve (6) having an elongated shape and comprising a lower section (9), an intermediate section, which extends longitudinally along an intermediate central axis (M), and an upper section (11) which extends longitudinally along an upper central axis (S), the upper central axis (S) and the intermediate central axis (M) being laterally offset from each other.

Description

[0001] The present invention relates to the general technical field of building ventilation systems and equipment, in particular MVHR (Mechanical Ventilation with Heat Recovery) systems, and also falls within the general field of construction, in particular the installation of roofs and coverings.

[0002] The present invention relates more specifically to a connection system between, on the one hand, an air network for the ventilation of a building, and on the other hand, a socket tile intended to be part of a roof of said building, comprising at least one sleeve intended to connect an air duct of the air network, such as a stale air or smoke exhaust pipe, to the socket tile, said sleeve having an elongated shape extending between an upper end intended to be turned towards the outside of the building and an opposite lower end intended to be turned towards the inside of the building.

[0003] The present invention further relates to a roof penetration assembly comprising such a connection system.

[0004] Air exhaust systems are generally used to remove stale air from buildings, such as homes and commercial and industrial facilities. These systems are designed to draw air from inside buildings and expel it outside. Mechanical ventilation systems (MVHR) are particularly well-suited for this purpose and include an air duct running from the room to be ventilated to an outlet opening to the outside, as well as an active ventilation device to draw the air out of the room through this duct and then through the outlet. MVHR outlets are typically located in the walls or roof of buildings.

[0005] In cases where the exhaust vent of a mechanical ventilation system (MVHR) is located on the roof, there are specific constraints regarding the installation of the air outlet systems. Indeed, particularly when the roof is tiled, it is preferable to respect the existing tile pattern when installing the MVHR system. In other words, the overall arrangement of the tiles should not be disrupted despite the installation of the MVHR unit and its associated air outlet at tile level. This is for both aesthetic and practical reasons: the general arrangement of the tiles in relation to each other and its associated aesthetic appearance, the type and color of the tiles (generally terracotta, for example, reddish), maintaining the mechanical protection and weatherproofing provided by the roof, etc.The installation of the VMC, and in particular the VMC air outlet located at roof level, must therefore allow air to be evacuated while preserving the general arrangement of the roof tiles.

[0006] To this end, known air outlet systems suitable for MVHR generally include a connection sleeve to an internal ventilation system (e.g., an MVHR duct), as well as a socket tile, which essentially consists of a tile equipped with a douille ", that is to say in this case a raised edge delimiting an air passage opening. The connecting sleeve, guided by said edge, is inserted into the air passage opening of the socket tile, and allows the latter to be connected to the internal ventilation system.

[0007] While known air outlet systems generally perform their function satisfactorily, they nonetheless have certain imperfections relating in particular to their installation, use, modularity, adaptability, cost or practicality.

[0008] In particular, conventional air vent systems are difficult to install with certain tile geometries and arrangements, especially tiles where the area covered by another tile—that is, the part of the tile that does not correspond to the gauge (in other words, the part of the tile that is not exposed to rain)—is relatively large in proportion to the total tile surface area, and / or exceeds a certain dimension. Thus, tiles adjacent to the vent tile are frequently obstructed by the space created by current air vent systems, particularly the sleeves of these conventional systems. The underlying roof battens in the immediate vicinity of the vent tile can also hinder or even prevent the installation of conventional air vent systems.

[0009] Furthermore, conventional air exhaust systems sometimes exhibit poor aerodynamic performance, particularly in terms of pressure drop in the outgoing airflow. Consequently, either the ventilation fans must expend a significant amount of electrical energy to expel the necessary quantity of air from the building, or the air is not properly (fully and consistently) expelled from the conventional exhaust system, or both problems occur simultaneously. These significant pressure drops associated with conventional exhaust systems can also result in intense and unpleasant continuous noise (due to the friction of the outgoing air), perceptible both inside and outside the building, thus disturbing the occupants or neighbors.

[0010] Furthermore, known air outlet systems are often, by their very design, complex to install at roof level, and require a substantial specialized workforce (often several people), and a long and tedious installation process, with associated costs and significant risks of installation errors.

[0011] Finally, known air outlet systems require special socket tiles which are sometimes difficult to integrate with other tiles on certain roofs or with the structure of the latter (underlying lintels, etc.), which can result in additional complications when installing such known systems, such as physical difficulty in setting up said systems and as well as an increased risk of error by the roofer, a lack of sealing or mechanical resistance of the roof, or even an aesthetic inconsistency due to the particular shape of the socket tiles adapted for these known air outlet systems, making said socket tiles stand out among the other tiles in a visually exaggerated and unpleasant way.

[0012] The objects assigned to the present invention are therefore aimed at remedying the various disadvantages listed above and proposing a new connection system between, on the one hand, an air network for the ventilation of a building and, on the other hand, a socket tile intended to be part of a roof of said building which, while being particularly easy to install, is also easily integrated into a very constrained environment such as the roof of a building.

[0018] Another object of the invention aims to propose a new connection system whose design allows it to be connected in a simple, secure and quick manner with a socket tile of a roof.

[0019] Another object of the invention aims to propose a new connection system between, on the one hand, an air network for the ventilation of a building, and on the other hand, a socket tile intended to be part of a roof of said building, which is suitable for connecting different types of air networks, and in particular standard VMC air ducts, without requiring any particular modification of said ducts.

[0020] Another object of the invention aims to propose a new connection system whose design allows for simple, economical and easy industrialization.

[0021] Another object of the invention aims to propose a new connection system between, on the one hand, an air network for the ventilation of a building, and on the other hand, a socket tile intended to be part of a roof of said building which, while being of a particularly compact and discreet geometry, is easy and quick to dismantle if necessary.

[0022] Another object of the invention is to propose a new connection system that requires only minimal maintenance.

[0023] Another object of the invention aims to propose a new connection system between, on the one hand, an air network for the ventilation of a building, and on the other hand, a socket tile intended to be part of a roof of said building whose installation does not degrade the external aesthetic appearance of said roof.

[0024] Another object of the invention aims to propose a new roof penetration assembly whose design allows it, on the one hand, to be particularly easy to install and integrate into a very constrained environment such as the roof of a building, regardless of the type of tiles on which said roof is equipped, and on the other hand to ventilate said building while minimizing aerodynamic pressure losses.

[0025] Another object of the invention aims to provide a new roof penetration assembly which has a particularly compact and discreet geometry, which is thus easy to install on all kinds of roofs and to match with all kinds of standard tiles, and which is also simple to manufacture, economical and easy to industrialize, while exhibiting excellent robustness and an aesthetic appearance ensuring great visual consistency to a roof equipped with standard tiles and said socket tile.

[0026] The objects assigned to the present invention are achieved by means of a connection system between, on the one hand, an air distribution network for the ventilation of a building, and on the other hand, a socket tile intended to form part of the roof of said building, comprising at least one sleeve for connecting an air duct of the air distribution network, such as a stale air or smoke exhaust pipe, to the socket tile, said sleeve having an elongated shape extending between an upper end intended to be turned towards the outside of the building and an opposite lower end intended to be turned towards the inside of the building, said connection system being characterized in that said sleeve comprises at least: a lower section, preferably of circular cross-section, extending longitudinally from the lower end to the upper end, and intended to be fluidly connected to the air network; an intermediate section, extending longitudinally along an intermediate central axis by extending said lower section towards the upper end of the sleeve, and having an elongated cross-section in a plane orthogonal to the intermediate central axis; an upper section intended to be connected to the socket tile, and extending longitudinally along a superior central axis by extending said intermediate section to the upper end of the sleeve, said upper section having an elongated cross-section in a plane orthogonal to the superior central axis, the superior central axis and the intermediate central axis being laterally offset from each other, said sleeve being rigid.

[0027] The objects assigned to the present invention are also reached using a roof penetration assembly comprising a socket tile intended to be part of a roof of a building, and a connection system as described above between, on the one hand, an air network for the ventilation of said building and, on the other hand, said socket tile.

[0028] Also described is a socket tile intended to be part of a building's roof, intended to be connected to the connection system as described above.

[0030] The invention relates, according to a first aspect, to a connection system 1 between, on the one hand, an air duct network (not illustrated) for the ventilation of a building, and on the other hand, a socket tile 2 intended to be part of the roof of said building. Indeed, when installing a ventilation system in a building whose roof is covered with tiles, it is necessary to connect the air duct network to a socket tile 2 in order to be able to expel air from the building, and / or to be able to draw air into the building (in the case of dual-flow mechanical ventilation systems in particular).The air distribution network is thus advantageously part of a ventilation system, which air distribution network preferably comprises a set of ducts for air circulation, including a stale air or smoke exhaust duct (and / or an outside air intake duct). The ventilation system advantageously comprises a mechanical ventilation device, generally consisting of one or more fans, i.e., one or more sets of blades rotating by means of an electric motor to draw air from within the building out of it (or conversely, draw outside air into the building), via the air distribution network. The connection system 1 is therefore preferably intended to (and designed to) be connected to an air intake duct and / or a stale air or smoke exhaust duct (not shown here), which duct is therefore part of the air distribution network.The said air distribution network is advantageously designed to be equipped with one or more fans, thereby forming a ventilation system as mentioned above. This ventilation system may be a mechanical ventilation system (MVHR), an air conditioning system, or any other similar system involving the extraction (and / or intake), preferably active (i.e., using a fan), of air from a building (and / or outside air into a building). The connection system 1 of the invention thus advantageously allows the exhaust pipe of the air distribution network to be mechanically and fluidly connected to the socket tile 2 of the roof. The socket tile 2 is, as its name indicates and as will be seen in more detail later, provided with a " douille that is to say, a through-hole 3 allowing air to pass out of the building itself (or outside air into the building, in the case of extraction). The air to be extracted from the building therefore passes from inside the building to the ventilation system, and more specifically to its exhaust pipe, then the air passes through the connection system 1, and finally the air exits outside via the socket tile 2 (this is obviously the reverse in the case of air being extracted from inside the building). The socket tile 2 is, as we will see, preferably designed to integrate harmoniously, both mechanically and aesthetically, with the other roof tiles 4, which are therefore preferably (at least for the most part) standard tiles 4 without a socket (that is to say, without a through-hole 3). An example of a standard tile 4 is given in the figure 4 , on the right. The socket tile 2 advantageously has an upper face 16, which is preferably (intended to be) turned towards the outside of the building (therefore turned upwards), and also preferably has a lower face 17, which is preferably (intended to be) turned towards the inside of the building (therefore turned downwards).

[0031] The invention further relates, according to a second aspect, to a roof penetration assembly 5 comprising a socket tile 2 intended to form part of a building's roof, and a connection system 1 as described above and below between, on the one hand, an air distribution network for the ventilation of said building and, on the other hand, said socket tile 2. Said socket tile 2 is preferably also that described above and below. The roof penetration assembly 5 therefore advantageously comprises at least the socket tile 2 and the connection system 1 as described above and below, the socket tile 2 and the connection system 1 being preferably designed to be mechanically connected to each other.The preceding description, like the following one, concerning the socket tile 2 and the connection system 1, therefore preferably also applies to the roof penetration assembly 5 according to the invention, and conversely, the following description concerning the roof penetration assembly 5 also preferably applies to the socket tile 2 and the connection system 1 according to the invention. Thus, the roof penetration assembly 5 advantageously allows either air (outside the building) to enter the ventilation system (and thus enter the building), or air (inside the building) to exit the ventilation system (and thus exit the building).

[0032] A third aspect also describes a socket tile 2 intended to form part of a roof, said socket tile 2 being intended to (and designed to) be connected to the connection system 1 as described above and below, said socket tile 2 preferably also being as described above and below. Obviously, the preceding description, like the following one, concerning the connection system 1 and the roof penetration assembly 5, therefore preferably also applies to the socket tile 2 according to the invention, and conversely, the following description concerning the socket tile 2 preferably also applies, for the common elements, to the connection system 1 and the roof penetration assembly 5 according to the invention.

[0033] According to the invention, the connection system 1 includes at least one sleeve 6 for connecting an air duct of the air network, such as a stale air or smoke exhaust pipe (the same as previously mentioned, not illustrated), to the socket tile 2.

[0034] The sleeve is preferably made of plastic, more precisely advantageously made of at least 90% (and preferably more than 95%, or even 100%) by weight of one or more polymer materials. Advantageously, any polymer material that provides the sleeve 6 with its own mechanical strength is suitable. For example, polypropylene is the polymer material.

[0035] The sleeve 6 is rigid, meaning it advantageously possesses inherent mechanical strength. Thanks to its rigidity, the sleeve 6 advantageously retains its shape under normal operating conditions. In particular, the sleeve 6 is not designed to be twisted and / or plastically deformed and / or permanently deformed by hand. One of the advantages arising from the rigidity of the sleeve 6 is that it can be held with one hand, particularly for insertion into the socket tile 2, which facilitates the positioning and installation of the sleeve 6, as will be explained in more detail below.

[0036] According to an advantageous embodiment of the invention, the socket tile 2 is made of terracotta, which remains the most traditional way of making a tile, particularly to ensure the best possible aesthetic match with other tiles, standard tiles 4 often also being made of terracotta. Alternatively, the socket tile 2 could possibly be made of plastic, composite, polymer, or even metal.

[0037] According to the invention, said sleeve 6 has an elongated shape extending between an upper end 7 intended to be oriented towards the outside of the building and an opposite lower end 8 intended to be oriented towards the inside of the building. In other words, the sleeve 6 advantageously extends in a general direction of extension between the upper end 7 and the lower end 8, the upper end 7 preferably being positioned facing the outside of the building, or even substantially outside the building, in particular just above the roof or at the level of the roof slope, while the lower end 8 is advantageously positioned facing the inside of the building, or even substantially inside the building, in particular just below the roof or within the roof.

[0038] The sleeve 6 is preferably designed to allow air (or other gas) to pass through it, and therefore includes, as illustrated in the figures, a side wall forming a conduit providing an air passage between said lower end 8 and said upper end 7.

[0039] According to the invention, said sleeve 6 comprises at least: a lower section 9, preferably circular in cross-section, extending longitudinally from the lower end 8 to the upper end 7, and intended to be fluidically connected to the air distribution network; an intermediate section 10, extending longitudinally along an intermediate central axis M by extending said lower section 9 towards the upper end 7 of the sleeve 6, and which has an elongated cross-section in a plane orthogonal to the intermediate central axis M; an upper section 11 intended to be connected to the socket tile 2, and which extends longitudinally along an upper central axis S by extending said intermediate section 10 to the upper end 7 of the sleeve 6, said upper section 11 having an elongated cross-section in a plane orthogonal to the upper central axis S .

[0040] In summary, said sleeve 6 advantageously comprises at least three sections different from each other, intended to be positioned successively from bottom to top, in the following manner: first the lower section 9 at the very bottom, then above this the intermediate section 10, then above this the upper section 11. Au-dessus " is preferably understood here as being intended to be located, once the connection system 1 is connected to the socket tile 2 (and therefore installed on / in the roof), at a higher altitude. Indeed, as will be seen, the sleeve 6 can be intended to be positioned substantially vertically, but it is preferably intended to be positioned substantially obliquely. Preferably, the sleeve 6 is not intended to be positioned horizontally, although this is not entirely excluded. Obviously, said side wall advantageously extends over said lower section 9, intermediate section 10, and upper section 11, from the lower end 8 to the upper end 7, and said lower section 9, intermediate section 10, and upper section 11 are therefore preferably formed by said side wall."

[0041] As described above, the lower section 9 preferably includes the lower end 8 and extends towards the upper end 7. The lower section 9 is advantageously intended to (and designed to) be connected (fluidically and mechanically) to a ventilation system exhaust pipe, in particular an exhaust pipe with a diameter between 120 and 200 mm, preferably between 140 and 180 mm, and even more preferably approximately 160 mm (+ / -5 mm), which is a very common standard diameter dimension among exhaust pipes in current ventilation systems. The connection system 1 is therefore particularly suitable for connection to a standard ventilation system already installed or to be installed within a building for its ventilation.

[0042] Preferably, said lower section 9 extends longitudinally along a lower central axis FAccording to a preferred variant, said lower section 9 has a substantially circular cross-section in a plane orthogonal to the lower central axis F The advantage of this configuration is that the air distribution network exhaust pipes generally have a circular cross-section. Alternatively, the lower section 9 may, in a plane orthogonal to the lower central axis, have a cross-section that is substantially in the shape of a regular convex polygon (square, regular convex pentagon, etc.), or oval, or oblong and / or elliptical. Preferably, the lower section 9 is rigid, that is, it has inherent mechanical strength.

[0043] As previously stated, the intermediate 10 and upper 11 sections each present, in a plane orthogonal to their respective central axis (intermediate M and superiorS (respectively), a respective cross-section that is elongated, that is to say, that advantageously presents in the relevant orthogonal plane a minimum dimension and a maximum dimension that are larger, preferably significantly larger, for example more than 20% larger, than said minimum dimension. Preferably, said maximum and minimum dimensions are measured inside the sleeve 6, which is preferably, as its name indicates, hollow. The figures 14 à 16 These illustrate cross-sectional views, facing outwards, of the aforementioned upper 11, intermediate 10 and lower 9 sections, illustrating their respective transverse sections in a plane orthogonal to the lower central axes F , intermediate M and superior S , respectively.

[0044] According to an important feature of the invention, the upper central axis S and the intermediate central axisM are laterally offset from each other. Thus, the upper central axis S and the intermediate central axis M are advantageously not confused with one another, and preferably do not intersect one another. In fact, the upper central axis S and the intermediate central axis M extend preferentially at a distance from each other, and are radially offset from each other, that is to say that at least in the vicinity of sleeve 6, the upper central axis S and the intermediate central axis M are spaced apart. Particularly advantageously, the upper central axis S and the intermediate central axis M are radially offset from each other. Put another way, preferably, for any plane that is orthogonal to at least one of the aforementioned superior central axes Sand intermediate central axis M and which, on the other hand, intersects with sleeve 6, the upper central axis S and the intermediate central axis M are both intersecting with said arbitrary plane respectively at a first and a second intersecting point, said first intersecting point and second intersecting point being located at a distance from each other (in the same arbitrary plane therefore).

[0045] Advantageously, the upper central axis S and the intermediate central axis M are roughly parallel to each other.

[0046] In summary, the connection system 1 of the invention thus advantageously allows the sleeve 6 to have the following characteristics: on the one hand, the upper section 11 and the intermediate section 10 each have an elongated cross-section, and on the other hand, there is an offset between the respective central axes (upper Sand intermediary M ) of said upper 11 and intermediate 10 sections, which essentially allows the connection system 1 not only: to be able to fit into particularly crowded geometries of roofing and tiles, as can be seen in particular at the figure 4 where a standard tile 4 can have a gauge (part exposed to the weather) conforming to the rest of the standard tiles despite the presence of the socket tile 2 and the sleeve 6 inserted in the latter, but also to have a minimum amount of aerodynamic pressure loss, i.e. to minimize the undesirable effects of friction of the air expelled from the building via the connection system 1, in particular due to the particular geometry of the upper 11 and intermediate 10 sections.

[0047] The minimum dimension present at the cross-section of the intermediate section 10 is essentially advantageously translated into a narrowing of the section of the latter along a direction of minimum dimension substantially perpendicular to the intermediate central axis M , as can be seen in the figure 4 This allows for additional space (lateral and / or radial) under the socket tile 2, where a portion of the standard tile 4 can be placed, in particular a concealed portion 12 of the standard tile 4, separate from the exposed portion 13 of said standard tile 4. In the example illustrated in the figure 4 , each standard tile 4 thus presents an exposed portion forming a portion of the gauge 13 intended to directly receive the elements (rain, snow), said portion of the gauge 13 being, in the example illustrated in the figure 4 , noticeably convex (with the concave side facing the building, although other shapes are possible). The standard tile 4 also includes a portion 12 hidden by the adjacent tile, said hidden portion 12 being, in the example illustrated in the figure 4 , essentially flat (other shapes are obviously possible). When the adjacent tile is the socket tile 2, the specific geometry of the intermediate section 10 allows for this additional space while minimizing pressure losses despite the change in cross-section between the lower section 9 and the intermediate section 10. The specific geometry of the upper section 11 is quite similar to that of the intermediate section 10, as illustrated by the figures 14 et 15 This also contributes to minimizing pressure losses, while allowing easy connection to the socket tile 2 and minimizing the latter's bulk, particularly at the through-hole 3 of said socket tile 2. The configuration of the sleeve 6 according to the invention makes it possible, in particular, to obtain excellent aerodynamic performance, which thus complies with the French Environmental Regulation 2020 (RE 2020) and the AFNOR standard NF EN 13141-5 (pressure losses of roof outlets for mechanical ventilation systems). Preferably, said intermediate section 10 is rigid, that is to say, it has its own inherent mechanical strength.

[0048] Advantageously, the upper section 11 is (intended for and) therefore designed to be inserted at least in part within a through hole 3 (the one already mentioned) of said socket tile 2. Thus, the particular geometry of the upper section 11, in addition to the advantages already mentioned above, makes it possible to prevent unintentional rotations of the sleeve 6 when it is inserted within the socket tile 2, and facilitates the placement of the latter within the through hole 3.

[0049] According to a preferred embodiment of the invention, the respective cross-sections of the intermediate 10 and upper 11 sections each have a constant shape (i.e. substantially identical over the respective height of each of the two sections 10, 11).

[0050] The intermediate section 10 and the upper section 11 each advantageously have a cylindrical shape, said cylinder preferably being formed from a surface in space consisting of parallel lines, said cylinder being further preferably hollow. More advantageously, the intermediate section 10 and the upper section 11 each have a right cylindrical shape, and more precisely a right cylindrical shape with an elliptical, oval, and / or oblong base. The respective points of each of the intermediate central axes M and upper central axis Scan possibly be defined as the intersection, in each plane orthogonal to the parallel lines defining said cylinder, of the largest internal diameter with the smallest internal diameter of the section considered (intermediate section 10 or upper section 11), such that the intersection divides the largest diameter into two equal primary sections, and the smallest diameter into two equal secondary sections. The foregoing also applies advantageously, mutatis mutandis , to the lower section 9 and its lower central axis F Alternatively, but preferably leading to the same result as above, each of the central axes M, S , F , is advantageously formed of a succession of points, each point constituting a geometric center in the cross-section considered of the segment 9, 10, 11 concerned.

[0051] Advantageously, the respective cross-section of each of the intermediate 10 and upper 11 segments is oblong, that is to say, it advantageously has a shape that is longer than it is wide and whose angles (for example, four in number) are rounded.

[0052] According to a particular embodiment of the invention, illustrated in the figures, whether used alone or in combination with the foregoing, the respective cross-section of each of the intermediate 10 and upper 11 segments has a general shape of a closed plane geometric figure with two parallel segments and two opposing plane curves, each segment being connected to the two plane curves. Obviously, the two endpoints of each segment are each connected to one of the two endpoints of each plane curve.

[0053] The socket tile 2 preferably comprises, as already mentioned above, a through-hole 3 for receiving the upper section 11. The socket tile 2 further advantageously comprises, as illustrated in the figures, a rim 14 delimiting the through-hole 3 and extending around a central axis of penetration. The through-hole 3 advantageously has an elongated cross-section in a plane orthogonal to the central axis of penetration, which is preferably substantially parallel to or coincident with the upper central axis. S(when the sleeve 6 and the socket tile 2 are connected). Thus, the said through orifice 3, and by extension the rim 14, advantageously has a shape substantially conjugate to that of the upper section 11, since the said through orifice 3 is preferably designed to house at least a part of the upper section 11. When the connection system 1 and the socket tile 2 are connected, the rim 14 is therefore advantageously designed to surround a part of the upper section 11, the latter being in particular pressed against the inside of the said rim 14 (within the through orifice 3, therefore).

[0054] According to an advantageous embodiment of the invention, the lower central axis F and the intermediate central axis Mare offset laterally from each other. This allows the lower section 9 to have a standard (in particular, circular) shape while preserving the additional space mentioned above thanks to the particular geometry of the intermediate section 10, as illustrated in figures 1 à 7 The lower section 9, for example, is formed by a portion of tubing with a circular cross-section of 160 mm + / - 5 mm in diameter, easily adaptable to a drain pipe (from the ventilation system) of the same type and / or similar dimensions. Thus, the lower central axis F and the intermediate central axis M are advantageously not confused with one another, and preferably do not intersect one another. In fact, the lower central axis F and the intermediate central axis Mextend preferentially at a distance from each other, and are radially offset from each other, that is to say that at least in the vicinity of sleeve 6, the lower central axis F and the intermediate central axis M are spaced apart. Particularly advantageously, the lower central axis F and the intermediate central axis M are radially offset from each other. Put another way, preferably, for any plane that is orthogonal to at least one of the aforementioned lower central axes F and intermediate central axis M and which, on the other hand, intersects with sleeve 6, the lower central axis F and the intermediate central axis Mare both intersecting with said arbitrary plane respectively at a third and a second intersecting point, said third intersecting point and second intersecting point being located at a distance from each other (in the same arbitrary plane therefore).

[0055] Advantageously, the lower central axis F and the intermediate central axis M are roughly parallel to each other.

[0056] Thus, the lower central axis F the intermediate central axis M and / or the upper central axis S is / are preferably substantially parallel to the general extension direction of sleeve 6.

[0057] According to a particular embodiment of the invention, the cross-section of the intermediate section 10 is smaller than that of the upper section 11 and / or that of the lower section 9, as illustrated in figures 3 , 7 And 13 , 16This reduction in cross-section at the intermediate section 10 is advantageously limited, since the latter has an elongated cross-section (and of maximum dimension) in a plane orthogonal to the intermediate central axis M , which makes it possible to partially compensate for the reduction of the cross-section of said intermediate section 10 to its minimum dimension (width).

[0058] According to a particular embodiment, the sleeve 6 has the following dimensions, the width and length (or diameter) being given orthogonally to the respective central axis of each section 9, 10, 11, on the outside of each section 9, 10, 11, while the height is given in a direction parallel to the respective central axis of each section 9, 10, 11: the lower section 9 has a circular cross-section with a diameter of 160 mm + / - 10 mm, and a height of 95 mm + / - 5 mm; the intermediate section 10 has an oblong cross-section, with a width (minimum dimension in the cross-section) of 115 mm + / - 10 mm, a length (maximum dimension in the cross-section) of 175 mm + / - 10 mm, and a height of 60 mm + / - 5 mm; the upper section 11 has an oblong cross-section, with a width (minimum dimension in the cross-section) of 135 mm + / - 10 mm, a length (maximum dimension in the cross-section) of 175 mm + / - 10 mm, and a height of 40 mm.

[0059] According to the embodiment illustrated in the figures, said sleeve 6 further comprises a lower transition section 20 connecting the intermediate section 10 to the lower section 9, said lower transition section 20 having a cross-section with the intermediate central axisM which varies, and which preferably decreases progressively between said lower section 9 and said intermediate section 10.

[0060] Independently or in combination with the foregoing, said sleeve 6 further comprises an upper transition section 21 connecting the intermediate section 10 to the upper section 11, said upper transition section 21 having a cross-section to the intermediate central axis M which varies, and which preferably increases progressively between said intermediate section 10 and said upper section 11.

[0061] According to a particularly advantageous embodiment of the invention, the connection system 1 comprises a locking means, designed to lock the sleeve 6 in translation relative to the socket tile 2 in at least one direction parallel or coinciding with the upper central axis. SIn other words, the locking means is preferably designed to lock the connection system 1 to the socket tile 2, and more specifically to lock the sleeve 6 within the through hole 3 of said socket tile 2, preventing any relative movement of the sleeve 6 with respect to the socket tile 2. More precisely, the locking means allows the sleeve 6 to be attached to the socket tile 2 by eliminating at least one degree of freedom (translation about the upper central axis). S) of the sleeve 6 relative to the socket tile 2, while the rotation of the sleeve 6 within the through-hole 3 is blocked by the particular geometry of the upper section 11 with its elongated cross-section inserted into the through-hole 3, which therefore advantageously also has an elongated cross-section substantially conjugate to that of the upper section 11 (thus eliminating another degree of freedom of the sleeve 6 relative to the socket tile 2). Naturally, the sleeve 6 is also advantageously blocked in translation along directions orthogonal to the upper central axis S By the very fact of being inserted into the through hole 3 of the socket tile 2, the rim 14 prevents the movement of the sleeve 6 in said directions. Thus, once the connection system 1 and the socket tile 2 are connected to each other, they advantageously have no degree of freedom relative to each other.

[0062] According to a first variant, the locking means comprises at least one lower stop 18, 19 provided at the level of the upper section 11 and / or the intermediate section 10, said lower stop 18, 19 being designed to bear against a lower face 17 (that already mentioned above) of the socket tile 2. This makes it possible to block the upward translation of the sleeve 6, essentially preventing the latter from exiting the socket tile 2, which could compromise the installation of the connection system 1, its connection to the ventilation network, or the arrangement of the tiles. According to a particular embodiment of this first variant, illustrated in the figures, said lower stop 18, 19 comprises at least one first lower lug 18 and / or a second lower lug 19, each projecting outwards from the sleeve 6 (preferably from an external surface thereof) and integral with it.The said first lower lug 18 is located at a higher altitude than the second lower lug 19, for example with respect to the vertical or the upper central axis. S(which preferably extends obliquely). For example, said first lower lug 18 is positioned at the level of said upper section 11 (and connected to it), and said second lower lug 19 is positioned at the level of said intermediate section 10 (and connected to it). Said first and second lower lugs 18, 19 are advantageously formed from the same material as said sleeve 6, which simplifies and speeds up the manufacture of the connection system 1 while giving it excellent robustness. It is obviously possible that the lower stop means 18, 19 may comprise only said first lower lug 18 or only said second lower lug 19. However, when these last two lugs 18, 19 are present, they allow the sleeve 6 to be wedged more stably and securely against the underside of the socket tile 2, since they are located, relative to said sleeve 6, at different heights.The lower stop means 18, 19 preferably comprises several distinct and spaced first lower lugs 18 having the same function, for example at least two first lower lugs 18 as illustrated in the figures.

[0063] The sleeve 6 may have at least one, preferably at least two, shims 15 intended to bear against the rim 14 of the socket tile 2 inside the through orifice 3. The shim(s) 15 advantageously each project outwards from the sleeve 6 (preferably from an external surface of the latter) at the level of the upper transition section 21 and / or the upper section 11 (and connected to said section 21, 11), and are more advantageously made of material with one and / or the other of said upper transition section 21 and / or upper section 11.

[0064] According to a second variant, implemented independently or in combination with the preceding one, the locking means comprises at least one upper stop means 22, 23 provided at the level of the upper section 11, said upper stop means 22, 23 being designed to bear against an upper face 16 (that already mentioned above) of the socket tile 2. This makes it possible to block the downward translation of the sleeve 6, essentially preventing the latter from sinking further into the roof and the building, which could compromise the installation of the connection system 1, its connection to the socket tile 2, or even the roof's watertightness. According to a particular embodiment of this second variant, illustrated in the figures, said upper stop means 22, 23 comprises at least one upper lug 22 projecting outwards from the sleeve 6, preferably from an external surface of the latter.The upper lug 22 is preferably positioned at the level of the upper section 11 (and connected to it), above the possible first and second lower lugs 18, 19. More precisely, the upper lug 22 is preferably positioned at the level of the upper end 7, as illustrated in the figures. The upper lug 22 is advantageously formed from the material of the sleeve 6. Obviously, the upper stop means 22, 23 preferably comprises a plurality of distinct and spaced upper lugs 22, but all advantageously performing a similar function, namely, abutting against and above the upper face 16 of the socket tile 2. For example, as illustrated in the figures, the upper stop means 22, 23 comprises four upper lugs 22.

[0065] According to a particular embodiment of the aforementioned second variant, the upper stop means 22, 23 is designed to undergo elastic deformation and thus, by virtue of this deformation: of an initial configuration, before the insertion of the upper section 11 into the through orifice 3, as illustrated in particular in figures 1 And 2 , to a deformed configuration (not illustrated), where said upper stop means 22, 23 mechanically interacts with the socket tile 2 (and more specifically with the inside of the rim 14) during the insertion of the upper section 11 into the through orifice 3, then to a final configuration, which is substantially the same as the initial configuration, at the end of the insertion of the upper section 11 into the through orifice 3, said upper stop means 22, 23 then being supported against the upper face 16 of said socket tile 2.

[0066] Preferably, the upper section 11 is rigid, that is to say, it has inherent mechanical strength. However, the upper stop means 22, 23 is advantageously flexible, in order to be able to withstand the aforementioned temporary elastic deformation.

[0067] In other words, such a configuration advantageously allows the sleeve 6 to be fitted into the through hole 3 of the socket tile 2 and easily attached to the latter by snapping it into place (using the lower stop means 18, 19 and upper stop means 22, 23), said snapping being preferably reversible. It is thus possible to insert the sleeve 6 into the through hole 3 of the socket tile 2 from below, for example by pushing said sleeve 6 upwards into the socket tile 2, thereby causing the upper stop means 22, 23 to deform elastically, until said upper stop means 22, 23 can deform again to return to its final configuration where it bears against the upper face 16 of the socket tile 2.This allows an operator (for example, a roofer) to install the socket tile 2 on the roof, then push the sleeve 6, for example with one hand thanks to the rigidity of said sleeve 6, into the through-hole 3 until it clicks into place. This considerably facilitates the installation of the roof penetration assembly 5, not only from a practical point of view, but also in terms of labor, as only one person is needed, particularly for pushing the sleeve 6 into the through-hole 3. Of course, it is also possible to pre-assemble the roof penetration assembly 5 by connecting the socket tile 2 to the connection system 1 (and more specifically to the sleeve 6) in the manner of the [previous example]. figure 10 , then to place the socket tile 2 on the roof, easily aligning it with the adjacent tiles (especially the adjacent standard tiles 4) as illustrated in particular by the figure 4 This is achieved, in particular, through the specific geometry of the upper section 11 and the intermediate section 10. Optionally, the roof penetration assembly 5 is pre-assembled, with the connection system 1 already connected to the socket tile 2, while advantageously the socket tile 2 is bonded to a riser 28, the latter preferably being bonded to a cap element 27. The riser 28 and the cap element 27 are described in more detail below. The bonding is carried out, for example, with enamel.

[0068] According to a particular embodiment, illustrated in the figures, said upper stop means 22, 23 comprises one or more through slots 23 provided in said upper section 11, said through slot(s) 23 allowing elastic deformation of said upper stop means 22, 23. For example, said upper stop means 22, 23 comprises, on either side of each upper lug 22, at least two through slots 23 made in the thickness of the upper section 11, a through slot 23 thus being provided on each side of said upper lug 22. Each through slot 23 advantageously extends from the upper end 7 to the lower end 8, although said through slot 23 is advantageously provided only in the upper section 11 (or, in the extreme, also in the upper transition section 21).Such a configuration with one or more through slots 23, preferably two through slots 23 surrounding each upper lug 22, makes it possible to form, at the level of the upper section 1, and more precisely at the level of the upper end 7, a kind of tongue (or foldable blade) incorporating the upper lug 22, as can be seen in particular at the . figures 1 , 2 , 5 à 7, 10, 13 et 14. When the upper section 11 is inserted into the through-hole 3, each upper lug 22 comes into contact with the inside of the rim 14 of the socket tile 2, causing the tongue to bend inwards towards the upper section 11, corresponding to the deformed configuration of the upper stop means 22, 23 mentioned above. When the upper section 11 is sufficiently inserted into the through-hole 3, the upper lugs 22 emerge from the hole and are therefore no longer in contact with the inside of the rim 14. The tongue unfolds and returns to its original position, as illustrated in particular in figures 10 And 14 . Each upper lug 22 is then preferably opposite and abutted against the upper face 16 of the socket tile 2, which corresponds to the final configuration mentioned above of the upper stop means 22, 23.

[0069] Advantageously, the rim 14 is provided, on the side of said upper face 16, with at least one recess 24 (designed for and) intended to receive said upper lug 22. Obviously, when the upper stop means 22, 23 comprises several upper lugs 22, the rim 14 is provided, on the side of said upper face 16, with a plurality of recesses 24, each recess 24 being (designed for and) intended to receive one of said upper lugs 22. Such a configuration makes it possible, in particular, to position, wedge, and attach the sleeve 6 more precisely, more easily, and more securely relative to the socket tile 2, while preventing any rotation of the sleeve 6 relative to the socket tile 2. To detach the sleeve 6 from the socket tile, it is sufficient to push the upper lugs 22 inward along the upper section 11, while simultaneously pushing the sleeve 6 downwards.The said blocking method is therefore, in this latter configuration, advantageously reversible.

[0070] As illustrated in particular by figures 9 And 11 à 13 The said socket tile 2 optionally includes, on its lower face 17, a first and a second flat 25, 26 intended to (and designed to) bear respectively against the said first and second lower lugs 18, 19. The said first flat 25 is therefore advantageously situated at a higher altitude than the second flat 26, for example with respect to the vertical, to the upper central axis S or even to the central axis of crossing. The first and second flat surfaces 25, 26 advantageously form part of the lower face 17 of the socket tile 2.

[0071] The sleeve 6 is preferably monobloc, meaning that it is advantageously formed from a single piece. In particular, according to this preferred variant, sleeve 6 is formed from a single piece of plastic, for example, by molding. This configuration is particularly advantageous because it allows sleeve 6 to be formed in a single step, providing it with excellent mechanical strength, while also improving the ease of installation of the connection system 1 on a roof, since there is no need to manage several separate parts of sleeve 6.According to an alternative variant (not illustrated), the sleeve 6 is formed of several distinct parts, for example a main part and an added part intended to be attached to and fixed to said main part, said added part comprising for example the upper stop means (or at least a part thereof) while said main part comprises the remainder of the sleeve 6. In this latter alternative variant, the sleeve 6 advantageously further comprises fastening means for securing, possibly reversibly, the main and added parts to each other, for example by snap-fitting.

[0072] In a manner known as such, the roof of said building extends, on the side of said socket tile 2, along a slope inscribed in a mean plane. Said upper central axis S and / or said intermediate central axis MThe vent(s) are advantageously substantially orthogonal to the mean plane, with a margin of error of 10° or less, preferably 5° or less. This simplifies the installation of the vent tile 2 and its associated connection system 1, as it eliminates the need for a perfectly vertical air inlet or outlet (as with chimneys). In certain roof configurations, this also optimizes the minimization of pressure losses. In other words, the through-hole 3 of the vent tile 2 is advantageously angled rather than vertical. More precisely, the central axis of the through-hole 3 is preferably angled, not vertical, although this is not entirely impossible.Thus, when the connection system 1 is connected to the socket tile 2, the general extension direction of the sleeve 6 is preferably intended to extend obliquely or alternatively vertically.

[0073] The roof penetration assembly 5 further advantageously includes a cap element 27 for positioning on the socket tile 2 to prevent rainwater from falling into the penetration orifice 3 while allowing air to escape from or enter the roof penetration assembly 5. Advantageously, said roof penetration assembly 5 further includes a riser means 28 for placing directly on the socket tile 2 to be interposed between the cap element 27 and said socket tile 2, as illustrated in figures 1 à 4The riser 28 is preferably designed to be positioned on the rim 14 so as to conceal at least part of the latter from external view. More advantageously, the riser 28 is preferably intended to be placed on the rim 14 to conceal the recesses 24, as well as at least part of the connection system 1, for example, the upper lugs 22. Said riser 28 provides the mechanical connection between the rim 14 and the cap element 27. Said riser 28 advantageously has a through-hole with an elongated cross-section, advantageously in a plane orthogonal to the central axis of penetration. Advantageously, the cross-section of the riser 28 is substantially similar in its general shape (and also in its dimensions) to that of the through-hole 3 and / or to that of the upper section 11.According to the embodiment illustrated in the figures, the riser 28 has a general ring shape. The cap element 27 and / or the riser 28 is / are advantageously made of terracotta, which preserves the overall appearance of the roof, particularly when the standard tiles 4 are also made of terracotta.
