FIELD OF APPLICATION OF THE INVENTION

The present invention relates to the field of verandas and in particular to adaptations to ensure the connection between its roof and its side walls in the best conditions. DESCRIPTION OF THE PRIOR ART

The design and construction of verandas presents difficulties in terms of the connection between the upper part of the vertical side walls (in particular those forming gables) and the lower surface of the inclined roof. Indeed, the dimensions of verandas are likely to vary. In addition, as the roof must have an angle of inclination necessary for the flow of water, the angle formed between the vertical walls and the roof may vary.

The upper part of the vertical side walls thus constitutes a variable portion according to the angle and the dimensions adopted by the veranda. This variable portion is then made to measure, which increases the cost of the veranda.

In addition, this upper part poorly made or carried out at the last moment may not perform the air tightness functions well. The connection with the roof and that with the vertical wall may then not be optimal.

Finally, this upper part can be implemented by a cut piece which, blocking the triangular opening created, can have an unattractive aesthetic.

The integration of a gutter adds to these difficulties. Indeed, the gutter linked to the lateral edge of the roof follows the slope of the latter and must not come into conflict with the vertical side walls.

Likewise, the use of self-supporting panels of great thickness as constituent elements of the roof also makes it more difficult to connect with the upper parts of the vertical side walls since the elements which have to cooperate are of different natures. Such a connection sees panels cooperate

- 2 large, self-supporting inclines on the one hand with glazed walls framed by profiles on the other. Thus, the sealing and the aesthetics of this veranda part can be optimized. DESCRIPTION OF THE INVENTION

On the basis of this state of affairs, the applicant has carried out research aimed at facilitating the connection between the lateral vertical walls and the roof of a veranda-type construction so as to provide a solution optimizing both the tightness but also the aesthetics of this connection.

These researches led to the design and the realization of a device of connection between the vertical walls and the roof of a light construction of veranda type guaranteeing a good sealing in this high part and cooperating with a gutter in order to facilitate the water drainage.

According to the invention, the connecting device between the vertical walls formed of at least one carpentry frame comprising upper and lower crosspieces as well as uprights and the roof of a light veranda-type construction, said roof having an upper face and a lower face, is remarkable in that it comprises two modules:

- a first module which is fixed to the edge of the roof and which is equipped with a profile or a set of linear profiles formed. a horizontal portion preformed to receive at least one joint coming into contact with the underside of the roof, said horizontal portion following the inclination of said underside,. a downwardly projecting vertical portion having an internal face facing the interior of the building and an external face facing the outside of the building;

a second module which is fixed to said vertical portion by positioning itself against said external face of said vertical portion and on the upper cross member of the frame of the joinery constituting the vertical walls, the second module being equipped with a profile or a set of profiles incorporating a gutter profile, the fixing of the second module to said vertical portion allowing the position and in particular the inclination of the second module to be adjusted relative to the first module so that the

-3 first module follows the inclination of the roof and the second module rests on the upper cross member of said frame of the joinery constituting the vertical walls.

This characteristic is particularly advantageous in that it guarantees the sealing of the upper part of the vertical walls of the veranda with the roof. Indeed, the first module is equipped with a joint and follows the slope of the underside of the roof. By proposing a fixing on the roof itself, the contact between the underside and the joint is also guaranteed.

In addition, it authorizes the adjustment of the slope of the gutter which can rest on it, thanks to the breakdown into two modules of the device, on the upper cross member of the frame and therefore remain horizontal.

It is then no longer necessary to custom manufacture a profile or a plugging panel for this upper part since the device of the invention follows the slope of the roof, guarantees sealing with its lower surface and allows adjustment of the slope of the gutter which rests and thus fixes on the joinery of the vertical walls.

The assembly of the veranda is thus facilitated.

This device also offers improved aesthetics.

According to another particularly advantageous characteristic of the invention, said horizontal portion of the first module is broken down into at least two profiles or sets of profiles: one internal, the other external, each carrying a seal coming into contact with the underside of the roof, the two profiles or sets of profiles being separated by thermal break bars. Thermal insulation is thus highly optimized.

According to another particularly advantageous characteristic of the invention, said roof is constituted by an assembly of self-supporting panels. A roof made up of self-supporting panels facilitates the fixing of the device on the edges of the roof as well as the contact with the lower surface of the roof for the joints. Sealing is therefore optimized. The device of the invention facilitates the integration of self-supporting insulating panels in the structure of a veranda.

-4The structure of a traditional veranda (gutters and chassis) does not change, but such a device facilitates the support of such a roof since the gutters can rest on the high crosspieces of the joinery of the walls and the first module can follow the slope of the roof. This device thus makes it possible to apply a percentage of slope and in particular the 2% of slope necessary for the self-supporting panels forming the roof while preserving the structure of the veranda.

In order to adapt to this type of roof, according to another particularly advantageous characteristic of the invention, the device of the invention is remarkable in that said horizontal portion of the first module is preformed with an external horizontal projection to which comes attach the lower end of a fixing plate adopting the profile of a bracket coming to bear on the vertical outer edge of the self-supporting panel and on the upper surface of the self-supporting panel.

According to another particularly advantageous characteristic of the invention, said vertical portion of the first module receives on its internal face a vertical flat profile for covering. This vertical flat profile optimizes the internal aesthetics of the connection by hiding the fixing screws between the two modules.

According to another particularly advantageous characteristic of the invention, the set of profiles adopting the gutter profile of the second module is broken down into a vertical connecting part which comes to bear and is fixed against the external face of said vertical portion of the first module and a water recovery part adopting a U-shaped profile, the two parts being interconnected by bars of thermal break. The thermal insulation is therefore optimized over the entire height of the gutter.

According to another particularly advantageous characteristic of the invention, said vertical portion of the first module is positioned under the lower surface of the roof in connection with the profile or set of internal profiles of the horizontal portion. Thus, not only the two joints but also the connection zone between the first and the second modules are protected by the roof.

According to another particularly advantageous characteristic of the invention, the device comprises a vertical seal forming an accordion having folds deploying or retracting according to

-51 'distance or vertical approximation of the second module relative to the horizontal portion of the first module, the upper edge of said joint being fixed to the horizontal portion, the lower edge being fixed to the second module. This characteristic contributes to sealing and guarantees it despite the possible adjustment of the angular position. The presence of this seal prevents the penetration of water and air between the two modules constituting the device.

According to another particularly advantageous characteristic of the invention, the device comprises an element of insulating material interposed between the horizontal portion of the first module and the second module, said element being cut so as to fill the vertical space separating them. This element also participates in the insulation.

According to another particularly advantageous characteristic of the invention, the outer face of the vertical portion of the first module and the underside of the horizontal portion of the first module meet to form a groove open downwards with a semi-circular profile with which cooperates , when said faces come into contact for partial pivoting, the upper end of the vertical part of the second module which adopts the same profile. This partial pivoting will allow the device to position itself like a sand board at the horizontal lower end of the roof while following the slope of the lower surface of the roof for the first module and the verticality of the second module.

Another object of the invention is of course the veranda or the lightweight construction equipped with such a device.

The fundamental concepts of the invention having just been exposed above in their most elementary form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving by way of 'nonlimiting example, an embodiment of a device according to the invention.

DESCRIPTION OF A PREFERRED EMBODIMENT

As illustrated in the drawing in Figure 1, the veranda referenced V as a whole is juxtaposed against the wall M of a construction. In addition to the shared side common with said wall M, said veranda V comprises a roof 100, a vertical wall parallel to said wall M, two lateral vertical walls forming a gable (of which only 200 is visible in the drawing) perpendicular to said wall M.

As illustrated, the upper part 210 of the vertical side wall 200 joins the roof 100 which follows a slope for the purpose of discharging rainwater.

This roof 100 is formed by an assembly of self-supporting panels and is equipped on its three free edges (the fourth being in contact with the wall M) of a gutter C for recovery and evacuation of water.

As illustrated in the drawing in FIG. 2, the connection device D of the invention appearing in the various projected sections, provides suitable fixing of the channel C to the three flanges with a different vertical distance between the first module and the second module according to the desired slope difference between the two modules.

Indeed, as illustrated in the drawing of FIG. 3, the device referenced D as a whole proposes an adjustment of the position of the gutter C relative to the roof 100 as a function of the slope of the latter and of the fact that said gutter C remains horizontal by resting on the upper cross member of a fixed frame of carpentry of the sliding type with two openings which constitutes the upper part 210 of the vertical side wall 200.

To do this, the device D comprises two modules 300 and 400 which are fixed one on the other in an adjustable manner according to the double arrow Fl. The first module 300 is fixed to the edge of the roof 100 and the gutter C is supported and is fixed on the upper cross member 210 of the carpentry frame and is also fixed on the second module 400.

The first module 300 which is fixed to the edge of the roof 100 is equipped with a set of linear profiles formed by a horizontal portion 310 and a vertical portion 320.

The horizontal portion 310 is preformed to receive two seals 311 coming into contact with the lower face 110 of the roof 100. The horizontal portion 310 therefore follows the inclination of said lower face 110. It further breaks down into two sections 312 and 313 One of the sections 312 is said to be internal because it faces towards the inside of the veranda V and the other section 313 is said to be external because it faces towards the outside of the veranda V. The sections 312 and 313 each carry a seal 311 coming into contact with the underside 110 of the roof, the two sections 312 and 313 are braced by bars 314 of thermal break ensuring the insulation between the internal section 312 and the external section 313 of the horizontal portion 310. The almost all of this horizontal portion is located under the lower surface 110 of the roof 100.

Maintaining in position of said horizontal portion 310 is carried out as described below. Said horizontal portion 310 of the first module 300 is preformed with an external horizontal projection 315 which projects horizontally beyond the vertical plane defined by the edge of the self-supporting panel forming the roof 100.

This external edge defining the edge of the roof 100 defines a vertical plane on which comes to bear and fix itself

- 8 by screwing, a fixing plate 500 adopting the profile of a square. This bracket 500 includes:

- At the upper end 510, an internal projection coming to bear on the upper surface 120 of the roofing panel 100;

at the lower end 520, an external projection coming to be fixed by screwing a screw 530 to said external horizontal projection 315 of the horizontal portion 310.

The horizontal portion 310 is therefore clamped to the lower surface 110 of the panel forming the roof 100 and the contact of the joints 311 with this surface is guaranteed.

The vertical portion 320 of the first module 300 projects downward from the internal edge of the internal profile 312 of the horizontal portion 310. Consequently, said vertical portion 320 is positioned under the lower surface 110 of the roof 100. Said vertical portion 320 is part of said internal profile 312.

This vertical portion 320 has an internal face 321 oriented towards the inside of the veranda V and an external face 322 oriented towards the outside of the veranda V.

The vertical internal face 321 accommodates a vertical flat covering profile 600.

As illustrated, the vertical external face 322 serves as a support and attachment plane for the second module 400 on which the gutter depends

vs.

In fact, this second module 400 is fixed by screwing to said vertical portion 320 by positioning itself against said external face 322. The second module 400 is formed by a set of profiles taking up the profile of the channel C.

This set of profiles adopting the profile of the channel C is broken down into a vertical connection part 410 which comes to bear and fix against the external face 322 of said vertical portion 320 and a water recovery part 420 adopting a U-shaped profile.

These two parts 410 and 420 are interconnected by bars 430 for thermal break.

Advantageously, the thermal break bars 314, 430 as well as those of the frame of the joinery forming the vertical wall 200 are almost aligned.

The external branch of the U-shaped profile 420 forming the channel C is enhanced by a vertical profile 440 in order to guarantee the recovery

- 9waters despite the thickness of the panel forming the roof 100. This extension thus takes into account the difference in height between the lower surface 110 of the roof panel 100 to which the first module 300 is fixed and the upper surface 120 of said panel roof 100 on which the water to be recovered flows.

As illustrated by the drawings of the different figures 5, 5a, 5b and 5c or by comparing between the drawings of Figures 3 and 4, the attachment of the second module 400 to said vertical portion 320 of the first module 300 is adjustable so as to allow the channel C to rest and to be fixed by screwing on the horizontal crosspiece while being linked to the first module which follows the slope of the roof by being connected to the edge of the roof 100.

Thus, according to the drawing of FIG. 4, the second module 400 is placed in a lower position relative to the lower surface 110 of the roofing panel 100 and corresponds to a position more upstream of the slope (such as that illustrated on the drawing of Figure 5b).

This vertical adjustment according to the double arrow F1 thus authorizes the adjustment of the inclination of the second module 400 with respect to the first module 300, that is to say of the gutter C with respect to the inclination of the roof 100 despite the fact that the first module follows the slope of the roof 100 and the second follows that (horizontal) of the joinery forming the vertical lateral wall 200.

This setting also makes it possible to use the same device D both for the lateral roof edges according to the slope, as for the horizontal lower roof edge which does not have a slope. The connection between the various channels is greatly facilitated. This setting finally guarantees good insulation and good sealing.

In order to optimize this sealing and this insulation, the device D comprises several elements taking into account the change of angle along the slope.

Thus, the device D comprises a vertical seal 700 forming an accordion having folds that deploy or retract according to the distance or the vertical approximation according to the double arrow F1 of the second module 400 relative to the horizontal portion 310 of the first module 300. Indeed, as illustrated, the upper edge 710 of said accordion joint 700 is fixed to said horizontal portion 310

- while the second lower 72 0 is fixed to the internal arm of the U-shaped profile of the set of profiles 420 forming the channel C.

Similarly, the device D comprises a vertical element 800 of insulating material interposed between the horizontal portion 310 of the first module 300 and the second module 400. This element 800 is cut so as to fill the vertical space separating the two modules. It has an upper edge 810 along the slope of the first module 300 since it comes into contact with the lower surface of the horizontal portion 310 and a lower edge 820 along the slope (horizontal surface) of the second module 400 since it comes into contact with the upper bar 430.

This element 800 is only inserted when this is justified, namely when the contact surface between the external vertical face 322 of the first module 300 and the vertical connecting part 410 of the second module is no longer protected from the outside due to the fact too large a gap.

As this appears more clearly in a position where the first and second modules are separated (such as that illustrated by the drawing in FIG. 4), the external face 322 of the vertical portion 320 and the underside of the internal profile 312 of the portion horizontal 310 meet to form a groove open downwards 316 with a semi-circular profile.

As illustrated, the high end 411 of the vertical connection part 410 of the second module 400 adopts the same profile to cooperate with said groove 316 when they come into contact such as the position illustrated by the drawings of FIGS. 3 and 5c, at partial pivoting ends. Indeed, the edge of the lower end of the self-supporting panels has an angle relative to the vertical angle caught by the pivot in order to keep the gutter horizontal.

It is understood that the device, which has just been described and shown above, has been for disclosure rather than for limitation. Of course, various arrangements, modifications and improvements could be made to the example above, without however departing from the scope of the invention.
