DEVICES FOR VENTILATION OR AERATION AND / OR LIGHTING

  DESTINED TO BE PLACED IN WALL OF THE BUILDINGS

  The present invention relates to ventilation or ventilation and / or lighting devices intended to be placed on the walls of buildings,

most commonly on the roof.

  Devices of this type are known such as lanterns, windows with snuffboxes, or smoke outlets. These devices, besides their specific functions all have an imperative which is the sealing of their connection to the wall on which they are attached. For simplicity will be used in the remainder of this paper, for these walls the terms "roof" or "roof", it being understood that the devices concerned, although mainly applicable to roofs, can also be placed on walls

substantially vertical.

  These devices are placed on the roof and in a general manner, these roofs have a relief for stiffening the roof elements, and guide water flows. Frequently, this relief is in the form of ribs, directed according to the largest slope of the roof. For the installation of aeration or lighting devices, an aperture of corresponding size is provided or made in the roof; the device is placed so as to cover this opening, and is fixed to the roof. Means for sealing between the

  roof and the frame or chassis of the device are provided.

  In known techniques, sealing is commonly performed by interposing a seal of silicone sealant type between the roof and the frame of the device. This type of seal has several disadvantages. On the one

  On the other hand, it requires during the realization, a time of relative labor-

  This is aggravated by the difficulties encountered when working at heights on roofs. On the other hand, it is difficult to obtain a regular seal, and, in addition to an unsightly appearance, there is a risk of obtaining a questionable seal, especially as the seal thickness can be significant in

  the case of a pronounced roof relief.

  Other means are known to try to improve the connection between the frame of the device and the roof. In particular,

  devices whose frame is shaped according to the relief of the roof, and is therefore an element integrated into the roof. However, these devices can only be prefabricated or molded in the case of plastic constructions, and therefore can only adapt to a single profile of roof elements. It is then necessary for the manufacturer either to realize these devices on demand, or to store a large number of different models designed to adapt to each type of roof. These two solutions are not

  obviously not satisfactory from an economic point of view.

  It is also stated that an important aspect in these provisions

  sitives is the material in which they are made. Taking into account that these devices are directly subjected to the weather, the sun, the wind, the weight of the snow, etc., their constituent material must be able to

  resist all these constraints.

  The present invention aims to solve the various problems

  above mentioned, and to propose a device having very good qualities of weather resistance and waterproofness to rain and wind when

is placed on the wall of a building.

  To achieve these goals, it is proposed a ventilation device or

  lighting intended to be placed on the wall of a building and more particularly

  roofing, of the type comprising a fixed frame, and connecting means and sealing between the frame and said wall. According to the invention, the device is characterized in that the frame is composed of a rigid frame externally coated with metal sheets whose bottom part forms a curb whose two lateral sides follow the shape of the panels of the wall, the side upper (in the direction of the wall) is flat and located at a height corresponding to the low areas of the profile of the panels to be placed below them, the lower side has a flat part at a height corresponding to the high areas of the profile of the panels to be placed above them, and the flat part extending by a folded edge down and cut so as to

  marry the profile of the panels, closures in compressible material pre-

  formed according to said profile, being arranged between the roof panels and

  said lower and upper sides.

  Advantageously, the outer covering forming a curb consists of four sheets (one per side of the frame) of prepainted aluminum,

  the four sheets being interconnected by folding at the angles.

  Advantageously, the upper and lower sides of the curb have a curved middle part respectively connecting their

  flat parts at their upper parts covering the frame.

  Thanks to the different characteristics expressed above, the device according to the invention has a remarkable seal and its installation is greatly facilitated by the fact that the specific sealing closures: the different profiles of roof panels are prefabricated, and , except for the cutting of the folded edge of the lower side of the curb, it can adapt to many panel profiles, to the extent, of course

  o These do not have too different profiles of heights.

  Other features and benefits will appear during the

  description which will be given as an example of an embodiment of

  the invention, applied to zenithal lighting devices of covered premises.

  Reference is made to the accompanying drawings in which:

  - Figure 1 is a schematic perspective view of the device according to the invention.

  FIG. 2 is a section along the direction of greater slope of the

zenith lighting device.

  FIG. 3 is a sectional view of this device along the axis III-III of FIG. 2, showing on the left side the connection of the lateral side in the case of a single-insulation roof, and on the right part in

  the case of a roof with reinforced insulation.

  FIG. 4 is a view similar to that of FIG. 2, but in the case

  a roof with reinforced insulation.

  - Figure 5 is a top view of the frame and the translucent panel.

  - Figure 6 is a partial section of the device along line VIVI of Figure 5.

  It is specified that, in order to facilitate the reading of the different drawings, they are not all executed on the same scale and for the sake of clarity,

  some elements have been represented only schematically.

  Figure 1 shows the adaptation of the device on a roof formed of ribbed panels 1, 2, 3 and 5 which surrounds an opening 4. To facilitate understanding of the invention, the device and the two panels

  upper 5 and lower 2, are shown offset with respect to each other.

  It is easily understood that once the installation is complete, the lower side 11 is above the panel 2, and the panel 5 is above the

upper side 12.

  The device comprises a rigid frame 20 with walls perpendicular to the mean plane of the roof, externally coated with sheets 33, 34, 35 and 36 prepainted aluminum. The two sheets 34 and 36 forming the lateral sides 13 and 14, are folded to form the ribs 15 and 16 so as to match the profile of the ribs of the roof panels, and cover the ribs 6 and 7 at the edges of the opening 4. A seal strip 17 is interposed between the ribs 15 and 16 of the lateral sides 13 and 14 and the ribs 6 and 7 of the panels, before fixing by screwing by means of

self tapping screws 49.

  4 - The wall 35 has a solid portion forming the upper side 12 in the same plane as the non-ribbed portions of the lateral sides 13 and 14, and is placed below the edge of the upper panel 5, a sealing foil 18, preformed according to the profile of the roof panels, being interposed at the level of the covering. Fixing is also ensured by

  screws 49, in the recessed areas 5a of the panel 5.

  The sheet 33 forming the lower side 11 has a face

  plane 19, offset in height with respect to the side 12, by a corresponding distance

  laying at the height of the ribs 6 and 7 of the panels 2. In this way, this flat face 19 comes to cover the edge of the lower panel 2, and is extended by an edge 21 folded down substantially at right angles and having cutouts 22. the shapes of the profile of the panel 2, the edge 21 can thus marry precisely said profile. A counter-sealing profile 23 (not visible in Figure 1) is interposed between the flat face 19 and the edge of the panel 2 that it covers, the fixing being provided by screws 49

  placed only at the ribs of said panel.

  The links between the four sheets 33, 34, 35 and 36 are

  bending 24 and 25; bends are always made so as not to be an obstacle to the flow of water. Thus the fold 24 will be folded towards the lateral side, and the fold 25 will be folded towards the lower side. We find on the other figures the elements previously

  described. The drawing in Figure 2 shows in addition the constitution of the structure

  ensuring the rigidity of the device. We see the frame 20 consisting of panels 26 of plywood or similar material, coated internally and over its entire height, pre-painted aluminum sheets 27 and 28. These sheets are folded at their lower parts 29 and 30 to cover the

  lower edge of the panels 26. The lower part 29 extends parallel to

  at the upper or lateral sides 13 and 14 (see FIG. 3) with the interposition of a layer of rigid insulating material 31. The lower part of the sheet 28 corresponds to the lower side 19, is folded a second time upwards to form This provision is in particular intended to facilitate the installation of the device in the opening of the roof, the upper side 12 being slidable under the upper panel 5, and the lower side 11 can be applied on the lower panel 2, the fold 32 not constituting any inconvenience, and even possibly may constitute a guide during the introduction of the frame in the opening of

the roof.

  Note that the inner aluminum sheets 27 and 28, and outer 33, 34, 35 and 36 are not in contact, and therefore do not create a thermal bridge; leaves 35 and 33 are bent next

  a round of large radius to facilitate the flows.

  On the right side of FIG. 3 and in FIG.

  a variant of the invention adapted to. insulating roofs. In this variant, the panels 26 of the frame 20 extend downward a distance corresponding to the thickness of the layer of insulating material 31 'which is intended to correspond to the thickness of the insulation in place under the roof . Note in Figure 4 that the part. lower 29 'of the inner lining 27 covers all the insulator, the latter is maintained, by gluing on said portion 29' ,. as well as on the edge 12 of the outer sheet 35. Note that there is no thermal bridge, the leaves

  of aluminum inside and outside not meeting at any place.

  On the lower side (on the right of Figure 4), we note the absence of insulation, the insulation being made here by the material

insulation in place under the roof.

  The particular characteristics of the application of the invention to a zenith lighting device will now be described. In this

  application, a translucent panel 51 of polycarbonate plastic

  honeycomb triple wall is adapted to the frame 20 to close the opening tightly, while allowing a maximum of natural light. In addition, the triple wall honeycomb polycarbonate is remarkable for its light weight, its good coefficient of thermal insulation, its resistance to thermal and mechanical shocks, and a good preservation of these characteristics during aging. This material is already known,

  it is simply recalled that it consists of three leaves 51a, 51b, 51c parallel

  spaced apart and connected by longitudinal ribs 51d and 51e which define

  deny between them cavities 51f.

  According to the particular application of the invention, the translucent panel is mounted in a frame 52 made of aluminum profiles which fits on the

upper edge of the frame 20.

  The aluminum section 52 'has a preferred cross-section such as that shown in FIG. 6. It comprises in particular an upper tongue 53 directed towards the inside of the frame and under which the edge of the translucent panel 51 is slid. 5la superior of the panel is in contact with the edge of this tab, while the lower sheet presses a seal 54 housed in a recess - 55 of the profile 52. A game is reserved over the entire periphery of the panel between it and the part vertical 56, linked to the tongue 53 of the profile, so as to allow the free expansion of the

sign.

  - 6 With this arrangement and the maintenance of the panel pressed on the seal 54 by the tongue 53, the seal between the panel 51 and the frame 52 is permanently ensured. In addition, bores 57 are made in the profile located on the underside of the device to allow the evacuation of any condensates, or infiltrations between the upper face of the translu-

and the tongue 53.

  At the longitudinal ends of the panel 51, that is to say on the edges or open cells 51f, an angle 58 is glued by one of its wings 58a under the edge of the upper sheet 51a. The other wing 58b of the angle extends down over the entire thickness of the panel 51, is

  pressed against the edge of the panel and closes the cells in a

  time not waterproof. This system allows the circulation of air and the evacuation of condensates that can be created in the cells, but on the other hand limits the penetration and the proliferation of micro-organisms or insects.

in this one.

  The section 52 further includes on each side of the recess receiving the seal 54, two walls 59 and 60 perpendicular to the plane of the panel, and forming with the bottom of the recess 55 an inverted U-shaped rib which covers the upper edge of the frame 20. Between the wall 59 located towards the outside of the frame 52 and the aluminum sheets covering the outside of the frame is interposed a seal 62 sealing

between frame and frame.

  The frame is fixed to the frame by screws 63 passing through the wall 60 and screwed from the inside into the panels 26 of the frame

20.

  The profiles of the frame are cut on the tab and assembled by self-tapping screws 64 passing through a profile and axially screwed into

  grooves 65 of circular section of three respectively made

  on each side of the recess 55, and down the wall 59.

  In the central portion of the drawing of Figure 6 is shown an additional possibility of usingon the profile 52 'forming the frame 52. The profile 52 "is here rotated 90 so as to have the wall 60 upwards.This wall comprises a recess 66 similar to the recess in which is placed a seal, and it is placed in contact with the underside of the translucent panel 51. This arrangement is particularly intended for lighting devices having a large surface, the additional profile being placed in the intermediate position to support the panel 51, for example towards its middle, and to prevent it from bending.

  intermediate section is fixed in a manner similar to that described above.

  for the assembly of the frame 52, by screws 67 passing through the frame and -7 -

  screwed into the grooves 65 of the profile.

  The invention is not limited to the lighting device described above by way of example. In particular it can be applied to other devices intended to ensure the passage through a roof, chimney or ventilation duct for example. The frame can also receive the sleeping frame of a window or a smoke outlet; it is also specified that the device is not reserved for roofs or walls formed of

  ribbed panels, but can also be used on traditional roofs

  such as tiles, slates, etc.
