It is known roof traversing devices, described in particular in the patent document FR 2,238,826, comprising a plate, also called flashing, comprising a plate provided on its upper face with a dome, and a tubular element surrounded by a skirt of complementary shape to that of the dome, so that said skirt is able to cover said dome for angles of inclination different from the main axis of the tubular element relative to the normal of the plate, said tubular element passing through an opening of the dome. The skirt mounted on the dome forms a hinge or patella system for adapting the angle of inclination of the tubular element to the roof slope. The dome has a large opening and the tubular member is rotated to the desired angle of inclination so that the tubular member is vertically plumbed. This type of roof crossing device is very simple to install. However, after mounting the tubular member on the plate, it is necessary to rigidly attach the lower portion of the tubular member to the frame to ensure proper retention of the tubular member. To do this the lower part is fixed by means of a clamp mounted on a trestle which is fixed between two vertical rafters of the frame. This placement of a header and a clamp considerably extends the installation time of the roof penetration device. The purpose of the present invention is to provide a new roof crossing device to overcome the aforementioned drawbacks, which is particularly simple and fast implementation. For this purpose, the present invention provides a roof penetration device comprising a platen, also called a flashing, comprising a plate provided on its outer face with a dome, said dome forming on the inner face of the plate a corresponding recess. a tubular element surrounded by a skirt of shape complementary to that of the dome, so that said skirt is able to cover said dome for different angles of inclination of the axis

Figures 1 to 13 illustrate a roof crossing device according to the invention. With reference in particular to FIG. 8, the roof penetration device comprises a plate S, also called a flashing, and a tubular element T, formed here of an upper tube 6 provided with a skirt or bib 7 and A lower tube 8. According to FIGS. 1 to 4, the plate S comprises a plate 1 of substantially rectangular shape provided in its middle part with a dome 2. The dome is disposed on the upper face 1a of the plate, centered according to the longitudinal plane P1 of the plate, and forms a corresponding recess on the lower face lb of the plate. The dome 2 comprises a central wall 21 and two side walls 22. The central wall has a longitudinal section in a circular arc. In the illustrated embodiment, this central circular-arc wall extends over approximately 180 °, and its center of curvature C1 is disposed above the support plane P2 of the plate, through which the plate bears in abutment. on the structural members when mounting the plate. The side walls 22 are flat and extend parallel to the normal N of the plate. The central wall has a rectilinear cross section, or preferably an arc of a circle as illustrated in the figures. The central wall 21 of the dome has a plurality of breakable parts 210, some of which will be removed to form an opening 216 (Fig. 10) whose position will be adapted to the desired angle of inclination of the tubular element T. These breakable parts are formed by weakening lines formed on said central wall. The central wall has two weakening lines, called peripheral 211, and a plurality of so-called transverse weakening lines 212, parallel to each other, extending from one peripheral line to the other, so as to form parts breakable in the form of transverse breakable strips. Each peripheral weakening line 211 comprises a longitudinal portion 211a disposed substantially at the junction between the central wall 21 and a side wall 22, in line with the inner surface 22b of a side wall, said longitudinal portion being extended by portions. 21lb in an arc of a circle, preferably in a quarter circle, each 21lb arcuate portion of a peripheral weakening line joined substantially at the longitudinal plane P1 an arcuate portion of the other line of peripheral weakening. With reference to FIG. 5, each weakening line 211, 212 is formed by a main groove 213, preferably a V groove, formed on the inner surface 21b of the central wall 21, and a so-called primer groove 214, preferably V, formed on the outer surface 21a to the right of the main groove. This primer groove, whose depth is less than that of the main groove, serves as a primer to facilitate the removal of a breakable portion. With reference to FIG. 4, the breakable portions 210 extend over only a portion of the central wall over a corner sector 13.

On either side of the normal N passing through the center of curvature C1, a high side and a low side of the stage are defined, the high side being arranged above the low side when the stage is installed on a sloped roof. . Said angle sector R is offset from the normal N of the high side of the plate. In the illustrated embodiment, the breakable parts extend over a sector having an angle R of about 100 °, this sector is positioned relative to the normal N so that the tubular element can be mounted on the plate according to an angle of inclination is between a minimum angle α of 5 ° and a maximum angle α2 of 55 °, said sector extending from the bottom side of the platen about 20 ° of the normal and the low side of about 80 °. °. To facilitate removal of the breakable parts, the central wall advantageously comprises a transverse opening 215, which extends from a peripheral weakening line 211 to the other, at their longitudinal portions 211a, and which is centered substantially in the middle of the corner sector 13. Referring to Figures 2 and 4, the plate is provided with a lower well or tube stiffening 3 extending perpendicularly from the lower face lb of the plate. This stiffening well is formed of two longitudinal lower side walls 31 and two transverse lower walls 32, 33. Said lower side walls are arranged longitudinally, so that their inner surfaces 3 lb are arranged in the extension of the inner surfaces 22b of the side walls 22 of the dome. The lower side walls 31 are connected in ends by the lower transverse walls. A first lower transverse wall 32 is disposed on the high side, so that its inner surface 32b is in line with the inner surface 21b of the central portion 21 of the dome. The second lower transverse wall 33 is arranged on the lower side, so that its inner surface 33b is also arranged in the extension of the inner surface 21b of the central portion 21. The lower transverse walls have a cross-section in an arc of which the radius of curvature corresponds to the radius of curvature in cross section of the central wall of the dome. Each lower side wall 31 is stiffened by bracing walls 34, for example three in number, each

7 connected on one side to the outer surface 3la of a lower side wall and on the other side to the lower face lb of the plate. The lower side walls have an end edge 311 in an arc of a circle, with a center of curvature C1, and whose radius of curvature substantially corresponds to that of the central portion 21 of the dome, at its junction with the side walls 22. The second transverse wall 33 has a recess 331 for the passage of the lower part of the tubular element for large angles of inclination, said tubular element being abutted against the free edge of this transverse wall for an angle d maximum inclination az of the tubular element. On the low side, the lower sidewalls extend beyond the second transverse wall and have vertical end edges 312 (Fig. 2) through which the platen is abutted against a roof element during its operation. mounting, especially against a trench or a batt. According to FIGS. 6, 7, 8 and 11, the tubular element T is formed of the upper tube 6 and of a lower tube 8, both of circular section, the lower tube constituting the lower part of the tubular element which extends under the skirt and is arranged under the dome when the tubular element is mounted on the plate. The upper tube is provided at its lower edge of the skirt 7 of complementary shape to that of the dome to fit on it. The skirt comprises a central wall 71 of longitudinal section 25 in a circular arc and of circular cross section, whose radii of curvature substantially correspond to those of the central wall 21 of the dome, and two side walls 72 substantially parallel to the main axis A of the tubular element. The central wall extending over an angle sector y (Fig. 11), which is smaller than the angle at which the dome extends, i.e., less than 180 ° in the present embodiment, and substantially equal to or greater than the angle 13. The central wall comprises two diametrically opposed portions, a portion 7la of large size and a portion 7 lb of small size. To form the tubular element, the lower tube 8 is fitted into the upper tube. With reference to FIGS. 12 and 13, the upper tube 6 comprises an inner annular shoulder 61 against which

8

the upper edge comes into abutment during the assembly of the two tubes 6, 8. The lower tube is held in the upper tube by means of two diametrically opposite lugs 62 formed on the inner surface of the upper tube 6, which snap into place in diametrically opposed corresponding recesses 82 formed on the outer surface of the lower tube 8. The lower tube has two flats 81 diametrically opposed, at which said recesses 82 are formed. Each flat extends from the upper annular edge 83 of the lower tube to a lug 84 intended to snap against the edge 311 in an arc of the lower side walls to lock the tubular element on the plate. The diameter of the lower tube is defined so that the distance between the surface of the flats 81 substantially corresponds to the distance between the inner surfaces 22b of the side walls of the dome, the outer radius of curvature of the lower tube substantially corresponding to the radius of curvature of the 21 lb. arcuate portions of the peripheral weakening lines. The plate and the two parts of the tubular element are advantageously made of a plastic material, by thermoforming or injection molding, preferably by injection molding. Said plastic material is for example a polyethylene or polypropylene-based material, preferably comprising a filler, in particular reinforcing fibers, and a light stabilizer, for example a polypropylene copolymer containing reinforcing fibers. A description of the use of the roof penetration device according to the invention will now be described. Depending on the slope of the roof, breakable portions 210 are removed to form an opening 216 allowing the passage of the lower tube 8, so that the angle of inclination of the tubular element T is adapted to the slope of the roof, namely the maximum angle of inclination a2 of 55 ° in the illustrated example. Removal of the breakable parts can be achieved by means of a clamp, tearing each breakable portion along the lines of weakness that define it. For removal of the first breakable portion, the aperture 215 is used to pass the clip.

The opening 216 can be made before the installation of the plate S on the roof or, preferably, once the laying is carried out. After snapping the lower tube 8 into the upper tube 6, the resulting tubular element T is mounted on the plate S by inserting its lower tube 8 in the dome 2, through the opening 216 created, until the lugs 84 abut against the edge 311 in an arc. To facilitate the engagement of the lower tube in the dome via the opening, the lugs 84 are in the form of a ramp whose thickness increases progressively towards the upper edge 83, as visible in FIG. 13. With reference to FIGS. 10, 12 and 13, when the tubular element is mounted on the plate, its main axis A passes substantially through the center of curvature Cl of the plate. The lower tube 8 is supported at its flats 81 against the inner surfaces 22b and 3b of the side walls 22 of the dome and the longitudinal bottom walls 31, which ensures a good maintenance of the main axis A of the tubular element in the longitudinal plane P1 of the plate. In this maximum angle of inclination a2, the lower tube comes against the edge of the notch 331. The end edge of the small portion 71b of the central wall 71 of the skirt 7 comes substantially against the plate 1, its large portion 71a covering the breakable parts not removed from the dome. The lower tube is substantially wedged between an undrawn breakable portion delimiting the opening 216 and the semicircular edge of the dome defined by the portions 21 lb in a circular arc of longitudinal lines of weakness. To enhance the angular retention of the tubular member, the tubular member may be glued to the dome, by previously applying glue to the dome and / or the inner surface of the skirt, and / or one or more screws may be screwed through the skirt and the dome, for example at an annular rib 721 (Fig.6) on the outer face of a side wall of the skirt. In general, depending on the angle of inclination, the lower tube may be substantially wedged between two non-withdrawable breakable parts delimiting the opening or, when the tubular element is in an extreme inclination angle ai or a2, between a breakable portion and the semi-circular edge of the dome defined by the arcuate portions of the longitudinal lines of weakness. Depending on the angle of inclination, 2953239 io

the tubular element can be turned to place the large portion 71a of the skirt of the high side of the plate, so that the unretrieved breakable portions are covered by this large portion. To allow the lugs 84 to abut against the edge 311 of the lower sidewalls, said arcuate edge extends over an angle at least equal to the angular spectrum defined between a1 and a2. A circular marking 217 is advantageously provided on the outer surface 21a of the central wall 21 of the dome, this marking corresponding to the positioning of the tubular element for an angle of inclination of 45 °, which will indicate to the installer the breakable parts to be removed for this angle of inclination, which is the most common angle for slate roofs. In order to more easily define the breakable parts which must be removed to form an aperture adapted to the angle of inclination, regardless of this angle, the device advantageously comprises a removable spirit level vial 9. With reference to FIGS. 14 and 15, the level vial is bent along a radius of curvature substantially corresponding to that of the dome 2. The plate S 'illustrated in FIG. 14 differs from that illustrated in the preceding figures solely by the fact that it further comprises a longitudinal groove 217 disposed along the median longitudinal plane of the plate, and extending over the breakable parts. Once the plate fixed on the roof, the level vial 9 is positioned in the groove and is slid into the latter to locate the vertical. Once the vertical is located, the operator then knows the breakable parts he must remove to form the opening adapted to the roof slope. Figures 16 and 17 illustrate an upper tube of a tubular element according to an alternative embodiment. As before, the upper tube 106 is provided with a skirt 107 of shape complementary to that of the dome to fit on the latter. The skirt comprises a central wall 171 and two side walls 172. The central wall this time extends symmetrically on either side of the axis of the tube on an angular sector corresponding to that of the dome, namely the order of 180 °, and thus comprises two symmetrical portions 17la, 35lb. One portion 171b includes a plurality of breakable portions 1710. The breakable portions are defined by lines

he

transverse weakening elements 1712 formed on the central wall, which are similar to those 212 described above, extending on each side wall 172 by lateral weakening lines 1718. Each breakable portion extends on the central wall and the two walls lateral, the first breakable portion being delimited by the edges of the portion 171b and side walls 172. This upper tube 106 is associated with the lower tube 8 described above to form a tubular element which can be used with a plate without breakable parts, provided an oblong opening extending over the sector of angle R defined above. Fractable parts 1710 are removed according to the angle of inclination desired to allow mounting of the tubular element on the plate while covering the entire oblong opening, the portion 171b provided with the breakable parts being disposed at the top or bottom side of the platen according to inclination angle. The tubular element formed from this upper tube 108 can also be used with the plates S and S 'described above. The appropriate breakable parts will be removed to allow positioning of the tubular member on the platen. This embodiment ensures a good cover of the dome beyond the breakable portions 210 not removed from the dome and the opening 216, especially avoiding any upwelling by capillarity when the device is used for very small slopes or flat roofs. According to the use of the device according to the invention, the tubular element T of the device may be equipped at the upper end of its upper tube 6 of different hat patterns, as well as an inner tube extending coaxially in the upper tube 6 and the lower tube 8. Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it comprises all the technical equivalents. described means and their combinations if they fall within the scope of the invention.
