Description

The present invention relates to the general field of the building. She

  more particularly relates to verandah or canopy roofs comprising parallel chevrons adapted to carry roof panels, at least one inter-chevron spaces having a juxtaposition of an insulating opaque zone

  formed of one or more opaque and insulating panels, and a translucent zone formed of one or more translucent panels, such as glass, polycarbonate or polymethacrylate.

  This type of roof is interesting because the translucent area increases the clarity of the corresponding room. But on the other hand, this translucent zone does not generally have a good insulation coefficient, which can be a disadvantage, especially in hot or cold weather.

  The present invention provides an arrangement of this type of construction that allows the user, in a simple and very fast way, either to take advantage of the brightness conferred by the aforementioned translucent zone, or to ensure a continuity of insulation of the surface under roof.

  According to the invention, at least the rafters between which are placed opaque and translucent roof panels, are provided with longitudinal grooves which allow reception and sliding over at least part of their length, and in the direction of the slope , an internal occultation system in the form of an opaque panel (s) and complementary insulator (s), which complementary panel (s) are adapted to be positioned facing said or said roof panel (s) translucent (s) to ensure their masking and to achieve a continuity of roof insulation, or to be retracted into the bulk of the surface of said opaque roof panel (s) and insulators, to release the translucent surface available.

  According to a first embodiment, the occultation system in question consists of a single opaque and insulating panel whose lateral edges are able to slide each in a longitudinal groove arranged on the side of two chevrons vis-à-vis .

  According to another possible embodiment, this occultation system consists of a plurality of superimposed opaque and insulating panels, and the sides of the two chevrons vis-à-vis comprise a plurality of superimposed grooves for reception, each one of the side edges of one of said panels.

  According to an advantageous characteristic, the roof according to the invention comprises metal rafters provided with monobloc grooves made over their entire length to accommodate the occultation system or systems.

  According to a preferred configuration, in the inter-chevrons space or spaces equipped with a complementary concealment system according to the invention, the opaque and insulating roof panel (s) are arranged at the bottom and the translucent roof panel (s). are arranged in the upper part.

  Preferably, the complementary occultation system is arranged so as to preserve a space E between its upper face and the translucent roof panel or panels when it is in the active occultation position, this to allow air circulation. ; and the upper part of the corresponding space E is in relation to one or more discharge openings which are arranged in the ridge part and which open outwards.

  One or more fans devices can be arranged at the ridge of the building to optimize the evacuation of air, in particular air from the aforementioned space E.

  According to another embodiment of the invention, the lateral edges of the panel or panels forming the concealment system are equipped with added profiles provided with a longitudinal extension intended to slide in the receiving groove of the chevron. These extensions advantageously comprise an attached rod, forming a pad, to optimize the corresponding sliding.

  According to another feature, the lower end edge of the concealment system is equipped with an upwardly facing sealing brush.

  According to yet another particularity, the upper end edge of the occultation system is equipped with an attached profile provided with a seal intended to cooperate with the wall facing the ridge portion, when said system of occultation is in the active position, placed next to the translucent roof panel.

  In the case where the occultation system consists of several superimposed opaque and insulating panels, these panels are advantageously provided with brush-shaped means (s) intended to achieve a certain seal between them. They are also advantageously provided with stop systems adapted so that the operation of one of the panels causes the desired movement of the other or the other panels.

  Preferably, the panel or panels of the occultation system are operated by a cane. Still preferably, this or these occultation panels consist of a layer of insulating material (polyurethane or other) coated on both sides with an aluminum foil.

  But the invention will be further illustrated, without being limited in any way, by the following description of two particular embodiments, given solely by way of example and represented in the appended drawings, in which: FIG. 1 is a diagrammatic view, in perspective, illustrating the interior of a veranda or a canopy equipped with a roof according to the invention, the occultation systems being represented here retracted from the translucent part; FIG. 2 is a more detailed view of the veranda or canopy roof according to the invention, in longitudinal section along 2-2 of FIG. 1, the occultation system being here represented in the active position of masking the translucent part; - Figure 3 is an enlarged view in section along 3-3 of Figure 2; FIG. 4 is an enlarged sectional view along 4-4 of FIG. 2; - Figure 5 is a sectional view which details the sliding of the occultation panel on the receiving chevron; - Figure 6 illustrates an alternative embodiment of the occultation system, consisting of a plurality of superimposed panels.

  Figure 1 shows a veranda or a canopy, seen from the inside, whose roof portion is made of parallel rafters 1 which carry different roof panels.

  The rafters 1 extend from the upper part of the window frames 2 (or a load-bearing wall) to ridge 3, with a slope that can be between 4 and 50%.

  Roof panels located in inter-chevron spaces are, for some, in the form of opaque and insulating panels 5 which extend from the upper parts of window frames 2 to ridge 3; but at least one of these inter-chevron spaces comprises a juxtaposition of an opaque zone consisting of one or more opaque / insulating panels 6, and a translucent zone consisting of one or more translucent panels 7.

  In this case, FIG. 1 shows two inter-chevron lateral zones filled by opaque / insulating panels 5, which frame two central inter-chevron zones, each filled by a juxtaposition of an opaque / insulating panel 6 and a translucent panel 7. The opaque / insulating panels 6 are arranged in the lower part and the translucent panels 7 extend in the upper part, from the upper end of said opaque panels 6 to the ridge 3, to optimize the entry of light.

  The opaque and insulating panels 5, 6 are advantageously constituted by a layer of insulating material (for example polystyrene or polyurethane) whose two faces are covered with an aluminum foil. The translucent panels consist on their side in glass plates (possibly double glazing) or in polycarbonate sheets, polymethacrylate or equivalent ...

  Fixing the roof panels 5, 6 and 7 on the supporting rafters 1 is carried out by any technique known to those skilled in the art.

  According to the invention, the interglazing zones equipped with the juxtaposition of an opaque / insulating panel 6 and a translucent panel 7, comprise an internal occultation system, movable, capable of being able to be positioned opposite said translucent panel 7 to ensure its masking and to achieve continuity of roof insulation with the associated insulating panel 6, or to be retracted in the bulk of the surface of said opaque and insulating panel 6, to release the available translucent surface provided by the roof panel 7.

  The principle of this occultation system is illustrated in dashed lines in FIG. 1, by means of the reference numeral 8. In this figure, the two occultation systems 8 are represented in the retracted position, opposite the opaque and insulating panels 6. Their mobility in the direction of the slope of the rafters is illustrated by the orientation arrows 9.

  As will be detailed below in relation to Figures 2 to 6, each occultation system 8 is in the form of one or more panels whose lateral edges slide in grooves arranged along the length of the rafters 1.

  Figures 2 to 5 illustrate a first possible embodiment of a veranda roof or canopy according to the invention, wherein the occulting system 8 consists of a single sliding panel.

  As can be seen in Figure 2 which is a longitudinal section at an inter-chevrons space equipped with a juxtaposition of an opaque / insulating panel 6 and a translucent panel 7, the rafters 1 s extend sloping from the rainwater harvesting gutter 10 equipping the upper part of the window frames 2, up to the sealing flashing 11 which surmounts the wall-mounted sandpit 12.

  Of course, the present invention can quite apply to two-slope constructions joined at a ridge beam.

  These rafters 1 are made of aluminum profile. Their upper part serves to support the various roof panels 5, 6 and 7 above. Upper cowling profiles 14 provide sealing at the junction of the roof panels disposed on either side of the rafters 4; in this case, these profiles 14 provide sealing between the panels 5 and 6 (Figure 3) and between the panels 5 and 7 (Figure 4).

  In the lower part, under the means which allow the reception of the roof panels 5, 6 and 7, the rafters 1 comprise a longitudinal groove 16 arranged over their entire length, to ensure the reception and sliding of the occultation system 8 constituted here a single opaquisolant panel 17.

  Only the facing faces of the two chevrons 1 which guide the opaquak panel 17 may be provided with the aforementioned groove 16; however, preferably, the two lateral faces of each chevron are equipped with such a groove, to have a single type of chevron, and / or to be able to equip with a concealment system 8, two intersecting spaces juxtaposed, as shown on Figure 1.

  The grooves 16 are made in one piece in the profile constituting the chevron 1; the profile of these grooves 16 and the structure of the side edges of the panel 17 are adapted to ensure the optimal sliding of said panel 17, so that it can be positioned at will, quickly and easily, under the panel opaquelisolant 6, or under the translucent panel 7.

  The width of the opaque movable panel 17 corresponds approximately to the width of the inter-chevron space; its length is adapted according to the length of the roof panels 6 and 7, to be able to completely hide the translucent panel 7 once placed in the active position (Figure 2) and to be fully included in the bulk of the opaque-opaque panel 6, once retracted . In this case, the roof panels 6 and 7 and the concealment panel 17 have similar lengths; in this type of configuration with a single occultation panel, the translucent roof panel 7 has a length at most equal to that of the opaque-insulating panel 6.

  In FIG. 2, the sealed assembly zone 18 made between the opaqua-insulation panel 6 and the translucent panel 7 can be seen.

  The occulting panel 17 is advantageously a flat panel structure similar to that of the roof panels 5 and 6, that is to say consisting of a core of insulating material (polystyrene, polyurethane) coated on each side of an aluminum foil.

  On its side edges, this panel 17 receives inserts 20, for example aluminum, detailed in Figure 5. These profiles 20 comprise a U-shaped base 21 for attachment by embedding and / or gluing on the side edges of the panel 17; they further comprise a longitudinal extension 22 intended to be embedded in the receiving groove 16 of the rafters. The extension 22 advantageously comprises a longitudinal housing for receiving an attached rod 23, oriented downwards to come into contact with the base of the groove 16. This added ring 23 constitutes a pad to facilitate the sliding of the panel 17 in the reception grooves 16 of the rafters.

  The plastic material used for producing the pad 23 is chosen and adapted to facilitate the corresponding sliding of the panel 17.

  Once in place, the concealment panel 17 can be moved manually by a maneuvering rod 24 arranged at its upper edge.

  When it is maneuvered downward, in the retracted position, the lower edge of the panel 17 abuts against the inner part of the gutter 10. Its active occultation position of the translucent panel 7 (FIG. 2) is maintained by any means of adapted lock, for example by one or more rubber pads, judiciously positioned in the groove 16 to form a brake structure.

  The bottom end edge of the panel 17 is equipped with an insert profile 26 provided with a brush system 27 facing upwards. The upper end of this brush system 27 comes into slight contact with the underside of the opaque / insulating roof panel 6 to achieve a certain seal.

  On the opposite side, the upper end edge of the insulating panel 17 is also equipped with an added profile 28. This profile 28 is provided with a seal cooperating with the wall facing the ridge portion, here the sandbox 12, when the panel 17 is in the active position of occultation of the translucent panel 7.

  The corresponding section 28 can be used for fixing the end of the operating rod 24.

  In the active occultation position, a space E is preserved between the mobile panel 17 and the translucent panel 7.

  In the upper part, this space E opens facing opening (s) 30 in relation to the outside, arranged (s) in the ridge portion 3. The or openings 30 consist of grids and / or pivoting shutters .

  This configuration makes it possible to obtain air circulation from inside the construction, passing through the brush system 27 fitted to the lower end of the panel 17, the space E and the opening (s). , to ensure the evacuation of hot air likely to form between the two aforementioned panels 7 and 17. The air flow in question is illustrated by orientation arrows in FIG. 2.

  The evacuation of the air is optimized by the presence of one or more fans 32 arranged in the ridge portion 3. This or these fans 32 may be controlled by one or more thermostatic probes preferably placed under the translucent panel 7 .

  The panel 17 can be completely prepared in advance and the embedding of its side edges in the receiving grooves 16 of the rafters can be done through the available clearance. If this game is not enough, the panel 17 is only equipped with one of the profiles 20; it is fitted by this profile in one of the lateral grooves 16, then it receives by simply sliding the other lateral profile 20 previously fitted above in the corresponding groove of the chevron. The upper sections 28 and lower 26 are then put in place, and the different sections 20, 26, 28 are held by notched corner brackets.

  FIG. 6 illustrates an embodiment variant in which the concealment system 8 consists of several superimposed panels, each slidable in its own groove system.

  As can be seen in FIG. 6, this variant embodiment makes it possible to envisage the use of a translucent panel 7 of longer length than that of the opaque / insulating panel 6.

  Here, the translucent panel 7 has a length twice that of the opaque / insulating panel 6, and the concealment system 8 consists of two sliding panels 17 ', 17 ", each movable in its own groove system respectively 16' and 16 ".

  The two panels 17 'and 17 "have an identical length substantially corresponding to the length of the opaque / insulating panel 6. They have a structure similar to that of the occultation panel 17 described in relation to FIGS. 2 to 5. The two grooves 16 'and 16 "are arranged parallel to each other, on the sides of the rafters 1.

  In the retracted position, the two panels 17 'and 17 "are directly superimposed and placed in the space of the opaque / insulating panel 6. The panel 17' is placed above the panel 17".

  In the occultation position (FIG. 6), the top panel 17 'masks the lower part of the translucent panel 7, and the bottom panel 17 "masks the upper part of this panel 7.

  The upper end of the top panel 17 'and the lower end of the bottom panel 17 "cooperate by a system of stops, not shown, so that the operation of the bottom panel 17" by means of the rod 24 causes the panel from above 17 ', in order to obtain the desired telescopic deployment.

  The upper end of the top panel 17 'and / or the lower end of the bottom panel 17 "has a brush system (s) 34 sealing between the two panels. one of the panels is facing the opposite side of the other panel.

  Note that the sliding system of the movable panel or panels 17, 17 ', 17 "can be replaced by rolling members, rollers are then arranged on the lateral edges of the movable panels, and these rollers are rotated in bearings adapted grooves, or rails, arranged monobloc or not along the rafters 1.

  In the inter-chevron zones which are not equipped with the occultation system 8, the grooves 16, 16 ', 16 "of the rafters may be used for the reception of a cladding type facing or the like, which allows the interposition complementary insulation between the upper face of said facing and the facing roof panel.
