Description

The present invention relates to a roof window, that is to say a window intended to be integrated into a roof and commonly referred to as a recessed window.

Such a roof window consists in a known manner of a perimetric frame, integrated into the roof structure and on which is posited in principle an opening incorporating a glazing to bring into the room in which is installed the window of roof, natural clarity, outside fresh air when the opening is open.

DE2946514A1 discloses a window according to the preamble of claim 1.

It is known, with reference to Figs. 1a and 1b , to place a roof window Ft in a roof T by having on each side of the longitudinal members L of the frame Cs of the window, and in the direction of the slope of the roof, two gutters Cn designed to collect the rainwater streaming on the roof and coming especially from the upper part of the window. The slates Ad are arranged to overlap on the roof so as to cover laterally the outer edge of the two gutters Cn. The movable frame of the opening Ov is bordered by a perimeter return which covers the two inner edges of the two gutters Cn.

The result is a roof window that is relatively well embedded in the roof. However several disadvantages remain, the slates Ad are posed in door to false on the outer edge of the two gutters Cn while they overlap in the direction of the slope of the roof so that they are only applied punctually on said outer edge, and can thus crack, break during the day / night cycles, seasons. The sealing of slates at this location is achieved by a grout Jt made of cement and eventually disintegrated with time allowing moisture to seep under the slates. In addition, the Cn gutters are wide enough to collect rainwater during severe weather, which widens the width of the window and makes it less discreet.

In a second roof window construction presented on the Fig. 2 , two Nq latches are arranged on each side of the frame Cs of the window Ft, and in the direction of the slope of the roof T. Each node Nq is formed of a folded plate having an L configuration with a rising vertical branch Bv adjacent a lateral side of a longitudinal member L of the frame Cs and a horizontal branch Bh turned outwards and which is covered mainly by slates bordering laterally said frame. The rainwater runs off on the uncovered part of the horizontal branches of the two Nq nozzles. The seal is obtained by a bed of mortar, for example cement-based and lime, interposed between the horizontal branch of the noodles and slates. The movable frame of the opening ov is bordered by a perimeter return which covers the two inner edges of the two rising vertical branches Bv Nq. The slates are no longer mounted cantilevered. The width of the window is reduced compared to that described previously. However, the vertical branch Bv must have a recommended height h minimum of four cm measured above the slates so that the runoff can flow properly on the Nq nubs, during severe weather, that is to say without being able to pass over the longitudinal members L of the chassis Cs. This results in a projecting height of the window above the roof large enough to make the presence of the window unobtrusive.

Based on this prior art, the applicant sought a solution to design and install a window in a roof, so as to make it as unobtrusive as possible when it is laid, while remaining effective with respect to the deflection of runoff.

For this purpose, there is provided a roof window according to claim 1 comprising a fixed frame provided with two longitudinal longitudinal members, the window comprising two gutters; according to the invention, two cleats are fixed externally and laterally to both longitudinal spars and the two gutters are fixed on said two cleats, provision considered in the position of installation of said window, the window further comprising notches, each notquet comprising a plate intended to be covered by roof covering elements, such as slates, tiles, said plate being extended by a lateral edge by an overlapping means designed to cover the free edge of the outer side wall constituting the two gutters.

When the window is embedded in the roof, heavy rain runoff overflows over the overlapping means forming the nozzles to flow into the gutters. The height of the projecting portion of the window above the roof can be reduced to a minimum by adjusting the height position of the two cleats against the longitudinal longitudinal members of the frame. The window remains discreet on the roof.

According to the invention, the overlapping means is formed of a profiled shape having a U-shaped geometry returned with a first face extending substantially perpendicularly to said plate, followed by a second face adapted to cover the free edge of the outer wall. of a corresponding gutter which extends outwards, a third face extending substantially perpendicularly to the second face and being disposed opposite the first face, said third face so as to be able to to dive inside the said gutter.

By designing this geometry of noquet capable of diverting runoff from below into a gutter, the height of the projecting portion of the window, excluding the roof, can be limited to a minimum, of the order of one to two centimeters. The integration of the window remains discreet.

According to the invention, the third constituent face of the overlapping means of the notquet extends beyond said plate.

The runoff is diverted to the lowest level in the gutter.

According to an additional feature of the invention, each gutter is formed of a profile having, viewed from one end, a U-shaped geometry with an intermediate wall extended at its two edges by the outer side wall and by an inner side wall adjacent to the outer face of a corresponding longitudinal spar.

This geometry of the gutter is ideal for it to be fixed on a corresponding longitudinal spar.

According to an additional feature of the invention, the two free edges of the outer and inner side walls are folded towards the interior of the gutter to prevent rain splashing up the outside of said gutter.

According to an additional feature of the invention, several notches are used on each side of the window frame, the width of the means of overlapping of the nozzles increasing from their upper part to their lower part, in the laying position of said notches to obtain a mutual recovery properly adjusted and without gap between two noodles to follow.

In an alternative embodiment, a single noquet is used on each side of the window frame.

This noquet is suitable for cooperating with tiles of all sizes.

According to an additional feature of the invention, a runoff plate is disposed under the bottom cross member constituting said frame, a clamp being fixed transversely on said runoff plate to retain cover elements or a sheet metal plate, intended to mask said plate runoff.

Advantageously, the clamp is fixed on an intermediate profile for its adjustment in height.

The cover elements, the sheet metal plate, retained in said clamp can be positioned coplanarly to the roofing elements of the roof.

According to an additional feature of the invention, the runoff plate is laterally bordered by two flaps in which are respectively formed and in their upper part, two corridors, the two gutters connecting in the two corridors.

The water collected by the gutters flows on the bibs.

According to an additional feature of the invention, a transverse channel bordering the upper cross member constituting the frame, said channel being connected at its ends by two sections of gutter connected in the upper part of the two gutters.

It serves to divert, in the gutters, runoff from the top of the upper part of the window.

A roof T is presented on the Fig. 3 , in which a roof window 100 has been recessed. The roof T consists in particular of unrepresented faults supporting Cv chevrons. Lt battens are fixed at regular intervals on the chevrons Cv. Means of covering the roof, such as slates Ad are represented in a few copies to facilitate the reading of this Fig. 3 . They are fixed by hooks on Lt battens or on stiles.

The roof window 100 comprises a fixed frame Cf secured to the roof T and in which an opening leaf Ov is movably mounted between a release / opening position with respect to the fixed frame Cf and a covering position of said frame. The opening ov can be of the projection or tilting type.

On the Fig. 4 , the fixed frame Cf consists of two high Th and low Tb cross members joined at their ends by two longitudinal longitudinal beams Lg and Ld right. Two cleats Ts are attached laterally and outside the two longitudinal longitudinal beams L. They are provided with fixing lugs Pf for fixing the roof window on the roof structure and in particular on its rafters. The fixing tabs Pf present on this Fig. 4 , an angle geometry with a vertical face fixed on the outer face of the cleats Ts and a horizontal face intended to be fixed on the upper face of said rafters.

Two gutters 120 are respectively disposed on the two cleats Ts as suggested by the arrows F on the exploded view of this Fig. 4 .

On the Fig. 5 , we clearly visualize the two gutters 120 fixed over the two cleats Ts. The two gutters 120 are intended to collect and evacuate sandstone from the slope of the roof runoff running down the roof, laterally to the window and deviated by the upper part of said window.

Each gutter 120 is formed of a profile having, viewed from one end, a U-shaped geometry with an intermediate wall 122 extended at its two edges by two lateral walls, one external 123 and the other inner 124.

Notables 140, of a particular construction, are used to channel in the two gutters 120, the runoff flowing laterally to the window. On the Figs. 5 and 6 , the noquet 140 presented consists of a flat plate 142 extended by a side edge by an overlapping means 150 adapted to be capped from above, in the position of installation of the roof window, the free edge of the side wall external 123 of a corresponding 120 gutter. The overlapping means 150 is formed of a profiled shape having a U-shaped geometry returned with a first face 152 perpendicularly extending the flat plate 142, followed by a second face 153 which extends parallel to said plate and outwards , a third face 154 perpendicularly extending the second and being disposed vis-à-vis the first side 152. Given the method of manufacture of the noquet 140 by folding in a sheet of metal and which is specified below, it should not be considered in the strict sense the perpendicular disposition of the faces between them. A tolerance of several degrees is possible in folding, without departing from the scope of the invention. Moreover, the second face 153 may have a rounded profile.

So, and with reference to the detail view of the Fig. 5 , the flat plate 142 is covered at the end of the integration of the window 100 in the roof, by the slates Ad forming roof for the roof. The overlapping means 150 covers the free edge turned upwardly of the outer wall 123 of the gutter 120, so that the overflow water from the slates Ad, the rainwater falling laterally to the window, can only pass through the two gutters 120. With reference to the Fig. 6 the third face 154 is longer than the first face 152 by extending beyond the plate 142 to dive inside the corresponding gutter to channel the overflow water in said gutter. See in this regard the detailed view of the Fig. 5 . It will also be noted that the two free edges of the outer 123 and inner side walls 124 are folded towards the inside of the gutter 120 to prevent splashing by heavy rain from rising to the outside of said gutter.

Furthermore, the movable frame of the opening leaf Ov is bordered by a perimetrical return which covers, in the closed position of said opening, in particular the two edges of the inner side walls 124 of the two gutters 120.

Each noquet 140 is advantageously made of aluminum foil which is folded in several stages to give it the geometry that it displays on the Fig. 6 . The height of the overlapping means 150, considered from its flat plate 142, is calculated as a function of the height of the roof covering, that is to say precisely according to the thickness of the slates, the tiles when they are asked. It can be used for this purpose and with reference to Fig. 8 a tool Ot consisting of two plates Pq spaced from the width of the overlapping means 150 of the notch 140 and in which two stops Bt adjustable according to the height of the roof covering, allow to define by folding, the height of the means overlap 150 by folding the flat plate 142, as suggested by the arrow I. This tool can advantageously be used on the installation site of the roof window. The flat plate 142 is advantageously folded by pinching it between two sheets. The overlapping means 150 is wedged longitudinally by two stops disposed between the two plates Pq at their two ends.

With reference to the Fig. 4 , several noets 140 are preferably used on each side of the roof window 100. It is thus possible to install roof windows of different heights using a variable number of nozzles.

On the Fig. 7 , the notches 140 are capped during their installation on the roof by local overlap of their overlap means 150. The width of the overlap means 150 is variable. Thus, its width L measured in its lower part with reference to the position of installation of the notches, is greater than the width 1 measured in its upper part, to obtain a mutual overlap properly adjusted and without gap between two noodles to follow.

On the Fig. 4 , the evacuation of runoff from the top of the upper part of the window 100 is carried out via a transverse gutter Gt should be positioned against the high cross Th of the window. It is connected at its ends by two sections Tc of gutters that should fit into the upper part of the two gutters 120 as suggested by the arrows G. Thus the runoff water that flows on the roof cover, to the right from the window, are deviated in the gutters 120.

A cover plate Pr, bordered by two lateral wings A1 which descend on both sides of the window, makes it possible to mask the gutter Gt and its two connection sections Tc.

The lower part of the two gutters 120 is connected to two flaps Ba which frame a runoff plate Ps which should be arranged against the lower crossbar Tb of the fixed frame Cf of the window 100. The two gutters 120 are connected in two corridors Cl shaped in the upper part of the two flaps Ba, as suggested by the arrows H. These are preferably made of lead sheets.

It is possible to mask the bibs Ba and the runoff plate Ps by covering them with cover elements or a sheet metal plate. On the Fig. 3 , a clamp Pn is fixed transversely on the runoff plate Ps to retain slates Ad. Fig. 9 , the gripper Pn consists of a profile shaped so as to have two elastic jaws disposed vis-a-vis and between which are inserted to be retained the high slices of the slates Ad, the two jaws being joined by a wall of back. This clamp Pn is held on the runoff plate Ps via a profile Po fixed on an inclined portion of said runoff plate Ps. This profile Po comprises a fixing wall on said runoff plate, extended obliquely by a retaining wall and against which is fixed, for example by gluing with the press, the back wall of said clamp Pn. It is thus possible to predict the height of this gripper Pn with respect to the runoff plate Ps for fixing roofing elements (slates, tiles) so that they are coplanar with the other elements of roof covering. A binder, such as putty, is introduced into the clamp Pn, and then the edges of the cover elements are inserted into said clamp to hold them by clamping and gluing.

In the invention, and with reference to Fig. 5 , the recessed position of the roof window 100 is adjusted by the setting of the position of the brackets Ts on the longitudinal members Lg of the fixed frame Cf. This position is defined in particular by the thickness of the window, the thickness of the means cover (slates, tiles).

The installation of the window 100 of the invention in a roof is implemented in the following manner. The two gutters 120 are fixed on the two cleats Ts. The position of the cleats Ts is adjusted according to the thickness of the window, the thickness of the covering means. The fixed frame Cs of the window is placed in a roof opening by fixing it with the fixing brackets Pf, for example, on the rafters Cv.

We put the transverse gutter Gt with its two sections Tc gutters.

We put the cover plate Pr.

We put the runoff plate Ps.

The opening is mounted in the fixed frame Cf.

The studs 140 are placed from top to bottom on each side of the frame Cs of the window so that their overlapping means 150 cover the free edges of the outer walls 123 of the two gutters 120. The slates constituting the cover are laid. Where appropriate, cover elements underlying the window are mounted in the gripper Pn. A sheet metal plate can still be used to replace these underlying cover elements.

The construction of the window of the invention makes it possible to fit it judiciously into a roof, that is to say so that it barely protrudes from the covering elements of the roof. The part underlying its lower part can also be masked by cover elements or by a mask formed of a metal plate.

On the Fig. 10 , the cover of the roof T is made with Tl tiles.

On the Fig. 11 , the overlapping means 150 of the notches 140 covers the free edge of the outer lateral walls 123 of the gutter 120. The seating wall of the notquet 140 is defined to receive a corresponding Tl tile. She presents on this Fig. 11 , a convex wall 142 'with lateral projection, in the pose position of the notquet on the roof. This convex wall 142 'is visible distinctly on the Fig. 12 . It serves to perfect the seal between a tile and another tile of lower rank. It is in principle flat and then shaped by laying said tile over it. The latch 140 is preferably constructed in two parts, the seat wall 142 'for a tile, made of a flexible sheet of metal, such as lead, aluminum and which is laterally bordered by a rising vertical wall 143 which goes up inside the first face 152 of the overlap means 150. The two parts are assembled by stapling.

On the Fig. 13 , the noquet 140 is unique for each lateral side of the window. It is particularly suitable for collaborating with mechanical tiles, such as flat tiles Tl 'with lateral recess.

A flange 144 extends vertically the lateral edge of the plane plate 142 of the noquet 140 to carry the tiles.

A longitudinal rib 145 of clearance is formed on the flat plate 142 of the noquet 140 to carry the tiles and clear a space for the flow of rainwater. Deposition of a bonding foam is performed between the flange 144 and the rib 145 to block the passage of moisture outwardly from the fixed frame of the window. The noquet 140 is preferably manufactured in a single component to be used with tiles of any size.
