Description

VERANDA AND CHASSIS ROOF
MODULAR FOR ITS REALIZATION.

 The invention relates to a veranda roof, of the type comprising a cover formed from filling panels and carried, in the upper part, by a wall profile fixed horizontally against a rear wall, and in the lower part, by a facade profile arranged at the top of the veranda facade.

 Three essential qualities are sought after in veranda roofing production systems: sealing quality whatever the inclination of the cover, ease of installation and flexibility of adjustment of this inclination, finally simplicity of the system and reduced cost price. . These qualities are difficult to reconcile and none of the existing systems satisfactorily combines all of these qualities.

 Thus, certain systems make it possible to obtain an excellent seal but require a large number of profiles and have a relatively complex structure which incurs the cost.

 Other systems are simpler and more reduced in price, but they generally have leaks which constitute a very serious disadvantage.

 In addition, all known systems require during the fitting of delicate adjustment operations as well as the execution of precise bores to properly position the various elements of the roof as a function of the slope to be given to it.

 The present invention proposes to remedy the shortcomings of known systems, by providing a new roofing system which satisfactorily reconciles the qualities of tightness, simplicity of structure and ease of assembly.

 An essential objective of the invention is in particular to eliminate any delicate operation during assembly and to ensure an automatic inclination adjustment whatever the value thereof, any drilling operation being eliminated during assembly.

To this end, the veranda roof targeted by the invention, of the type comprising a wall profile adapted to be fixed horizontally against a wall, and a roofing carried in the upper part by the wall profile and in the lower part by a profile facade, is characterized in that
- the cover is in the form of several independent frames juxtaposed against each other along a horizontal direction, each frame of height corresponding to that of the cover being composed
a high cross section adapted to cooperate with the wall profile,
two chevron profiles, arranged on either side of the chassis and adapted to join in a sealed manner with the contiguous chevron profiles of the neighboring chassis,
a low cross member joining the two chevron profiles and arranged to be positioned in the vicinity of the facade profile,
and a filling panel framed by said profiles and fixed thereon,
- The wall profile and the top rail profile of each chassis include hooking and pivoting means combined, adapted to ensure the attachment of the top rail profile on the wall profile, leaving said high rail profile the ability to rotate around a horizontal axis parallel to its longitudinal direction.

 In particular, the wall profile comprises a short lower wing provided with the above-mentioned hooking and pivoting means, while the upper cross-sectional profile of each chassis comprises at its lower part the combined hooking and pivoting means of the former, these means being adapted to couple and hang together when the chassis is approximately horizontal and to lock so as to become inseparable when the chassis is tilted downward.

 Furthermore, according to another characteristic of the invention, the bottom cross section of each chassis comprises, in the lower part, a picking return, turned on the internal side and adapted to cooperate with picking pieces secured to the profile of fa frame to block the frame in abutment against said facade profile.

 Thus, the roof according to the invention is produced by means of modular frames which are produced in the workshop. The assembly is then limited to fixing, in a traditional manner in itself, the wall profile against the wall concerned, to present each chassis approximately horizontally so that its high cross section is located opposite this wall profile, to be coupled the means for hooking and pivoting these profiles and for tilting the frame, causing it to pivot down until it rests on the facade profile. Preferably, this support is produced at the level of the chevron profiles.

 I1 then suffices to lock the chassis in this position by means of the hooking pieces (for example two in number), these pieces being fixed on the front profile and caused to 'hang on the hooking return of the profile of lower cross member of the chassis.

 The following chassis is put in place in the same way; its transverse position (along a horizontal direction) is adjusted by simple sliding Until bringing it against the first, the chevron profiles of the two frames joining together in a sealed manner, as we will see it further.

 We understand the ease of installation of such a roof, which requires no drilling operation and includes only extremely simple operations within the reach of all non-specialists. In addition, the structure of each chassis is extremely simple (essentially: four profiles, two of which are identical and one filling panel) and assembly requires only one additional profile (wall profile) and simple hooking pieces (very simple structure) .

Furthermore, the roof according to the invention preferably has the following other characteristics, which combine to give it excellent sealing qualities.
the wall profile comprises an upper covering wing arranged to form a projection relative to the wall and carrying at its end a lip seal facing downwards,
the upper cross section of each chassis comprises an upper fin disposed below the aforementioned upper covering wing and extending in a plane very approximately parallel to the plane of the chassis so as to act as a support at the end of the aforementioned lip seal whatever the inclination of said chassis,
the upper cross section of each chassis has a core forming an incorporated rebate, the walls of which project from the side of the wall section and which opens on the opposite side in order to contain the corresponding edge of the filling panel,
the lower cross-section profile of each chassis carries, on the external side, a lip seal oriented downwards and arranged to come into abutment against the façade profile when the chassis comes to rest against said façade profile,
the lower cross-section profile of each chassis comprises two faces, located opposite and in the immediate vicinity of the filling panel and separated by 7 grooves containing a flexible seal resting along said profile against the filling panel,
each of the chevron profiles of each frame forms, on one face of its core, a rebate directed towards the filling panel and into which the corresponding edge of said panel penetrates,
each chevron profile comprises, located projecting from its core on the side opposite to its rebate, on the one hand, a fin provided with a flexible seal, on the other hand, two close fins, arranged so that the contiguous chevron profiles of the two neighboring frames, arranged in reverse positions relative to each other, interpenetrate, the two fins of one overlapping the fin of the other with support of the flexible joint, and vice versa .

 As will be better understood below, this gives a roof with good air and water tightness, both at the junction with the wall profile, and at the junction with the profile of facade and of the junction between chassis.

 The invention extends, as a new product, to a modular frame for veranda roofing composed of a filling panel of a type known per se and of a high cross section, a low cross section and of two chevron profiles> having the characteristics previously defined or which will be defined later.

 The invention also extends, as essential means for the production of modular chassis, to each of the constituent sections of said chassis, obtained in particular by spinning or extrusion in light alloy.

The invention described above in its general form will be better understood on reading the description which follows and on examining the appended drawings which present, by way of non-limiting example, a preferred embodiment; on these drawings which form an integral part of the present description
FIG. 1 is a schematic perspective view of a veranda having a roof produced in accordance with the present invention,
. FIG. 2 is a schematic perspective view of a modular frame from which said roof was made,
FIGS. 3, 4, 5 and 6 show in cross section the section of the profiles used in said roof,
. FIG. 7 is a section through a vertical plane AA of the mounted roof,
FIG. 8 is a partial section thereof through a plane BB perpendicular to the plane of the roof,
Figures 9a, 9b and 9c are explanatory diagrams of the assembly of said roof.

 It should be noted that, by "roof plan" or "chassis plan" or even "plane of filling panels", is meant the mean plane along which these elements extend.

 The veranda shown by way of example in FIG. 1 is leaned traditionally against a wall M and comprises conventional facades, such as a front facade provided with an upper facade profile F and lateral facades. These facades are of known type.

 The roof consists of several modular frames such as l, of the type shown in FIG. 2. These frames, the height of which corresponds to that of the roof, are juxtaposed along a horizontal line and held in the upper part. by means of a wall profile 2, said chassis resting at the bottom on the front profile F with a blocking which will be described later.

(The roof also comprises parts serving as covers on the sides, which can be of any known type and will not be described in detail).

Each mud frame 1 is constituted by a filling panel 3 which is framed on three sides by a high cross section 4, and by two pro-chevron 5 and 6; moreover, in the vicinity of its lower part, a lower cross-section profile 7 brings together, below the panel 3, the two chevron profiles 5 and 6 with the triple aim of stiffening the assembly, ensuring low sealing and to allow the chassis to be locked relative to the facade profile F. (In addition, a square 6 fixed its ends to the chevron profiles forms an embellishing cover at the base of the filling panel 3 and prevents it from sliding towards the low2
The filling panel 3 can be of any type known per se, hollow extruded plastic panel, solid panel, glazing, etc.

 To allow a better understanding of the structure of each chassis and its mounting, the wall profile 2 and the constituent profiles 4, 5 or 6, and 7 of said chassis are described in detail below, respectively with reference to FIGS. 3, 4, 5 and 6. These sections are preferably made of aluminum alloy.

 The wall profile 2 (Figure 3) has a core 9 which is called to bear against the wall by small rear ribs. In the upper part, this section is provided with a covering wing 10 which forms a projection sufficient to cover the upper cross section section 4 of the chassis whatever the inclination of the latter. At its end, this projection is slightly inclined downward and forms a groove 46 for the installation of a connection bar at the ends of the profile when the length of the roof exceeds the standard length of the profiles (generally 6 meters) .

 Immediately behind the inclined part, the wall profile 2 forms a seal-holder groove 11 in which is housed the heel of a lip seal 12 oriented downwards; the latter is intended to come into flexible abutment against the high cross section of each chassis.

 In addition, the wall profile 2 has at the rear and opposite the wing 10 a fin 13 called to be housed in a groove formed in the wall, (and which will be filled with a sealant).

 In the lower part, the wall profile 2 has a short lower wing 14 provided at its end with means allowing the attachment of each frame while allowing them to pivot. In the example, these means are constituted, on the one hand, by a wall 15 having a section in the form of a sector of a circle, on the other hand, by an ascending lip 16 having a bearing end 16a.

 The wall 15 forms a convex interior surface 15a whose transverse profile in the form of a sector of a circle is centered on a horizontal axis X situated above said surface substantially at the level of the bearing end 16a; in the example, this end has the shape of a rounded bead substantially centered on the axis X.

 Furthermore, the wall profile 2 has cells 17, 18 and 19 for fixing the covers on the sides of the roof, as well as ribs 47 in the vicinity of the core 9 in order to form grooves for the establishment of connection plates between profiles.

 The high cross section 4 (Figure 4) has a core 20 which forms an incorporated rebate 21 whose walls project from the side of the friend who is called to come opposite the web 9 of the wall profile; this rebate 21 opens on the opposite side in order to contain the upper edge of the filling panel 3.

 The upper cross section 4 further comprises an upper fin 22 which extends in a plane orthogonal to its core 20 and, therefore, parallel to the plane of the frame or of the filling panel; this fin 22 has a sufficient width to allow it, when the chassis is mounted, to serve as a support at the end of the joint 12 whatever the inclination of said chassis.

 In the lower part, the top cross section 4 is provided with means adapted to cooperate with the hooking and pivoting means (15, 16) of the wall profile, in order to allow the chassis to be hooked while allowing its pivoting. about an axis parallel to the longitudinal direction of the profile. These means are constituted, on the one hand, by a wall 23 having a section in the form of a sector of a circle, on the other hand, by a support structure 24 adapted to bear on the end 16a of the lip 16 of the wall profile and to be able to pivot relative to it.

 In the example, the support structure 24 is composed of two fins 24a and 24b arranged in inverted V, with a view to forming between them a rounded groove centered on a longitudinal axis Y; these fins 24a and 24b are shaped so as to be able to overlap the lip 16 of the wall profile, the bead 16a of the latter being housed in the aforementioned groove with coincidence of the axes X and Y; in addition, the fin 24a has at its end a short horizontal part to facilitate, during installation, the engagement of the bead 16a between the fins 24a and 24b.

 The wall 23 which is attached to the lower end of the fin 24b, forms a concave locking surface 23a centered on the axis Y, so as to be able to slide against the convex surface 15a of the wall profile when the profiles are coupled (broken lines drawn in Figure 3).

 The length of the wall 23 is provided such that this wall remains recessed with respect to the surface 15a of the wall profile (release position) when the chassis is in a position close to the horizontal, that is to say when the the core 20 of the high cross section 4 is approximately vertical. When the frame is inclined downward, the locking wall 23 engages below the convex surface 15a and locks the two profiles which become inseparable, while leaving the profile 4 the ability to rotate freely around 1 axis. X.

 I1 it should be noted that the upper cross section 4 has a height suitable for its upper wing 22 to be located below the covering wing 10 of the wall section in the coupling position described above.

 Furthermore, the upper cross section 4 has two cells 25 and 26 located at the base of its rebate 21 on the external side (relative to the chassis). These cells make it possible to fix, at the upper corners of the chassis, the profile 4 on the two chevron profiles, by means of fixing screws.

 Each chevron profile 5 or 6 (FIG. 5) has a core 27 which is provided on one face with a rebate 28 formed by two fins projecting with respect to said face; this rebate is intended to contain a lateral edge of the filling panel; its median plane coincides with the median plane of the core 27, so that the chevron profile can be caused, by its rebate 25, to overlap the edge of the panel in a position or in the inverted position.

 On the other side of its core 27, each chevron profile 5 or 6 further comprises, on the one hand, two close fins 29 and 30, one of which is disposed at the end of the friend 27, of on the other hand, a fin 31 arranged in the vicinity of the other end so as to penetrate between the two fins 29 'and 30' of another chevron section arranged in an inverted position opposite the first (broken lines).

 The fin 31 is provided with a joint groove 32 in which is housed the heel of a flexible joint 33 which will come to bear against the fin 29 ′ of the contiguous chevron profile. The walls of the groove 32 are arranged projecting from the external side, so as to delimit on the external face of the fin 31 a water drainage channel, guiding their flow downwards.

 In addition, the ends of the fins 29 and 30 as well as the fin 31 (at its groove 32) are biased to facilitate the interpenetration of the chevron profiles of the neighboring frames.

 Finally, the bottom cross section 7 has a cross section of the type shown in FIG. 6. This section comprises, at the top, two bearing faces 34 and 35 separated by a groove 36 called to contain a flexible seal 37 The support faces 34 and 35 are intended to come, by their ends, in external support against the rebate 28 of the chevron profiles 5 and 6: in this position, said faces are located in a plane parallel to the filling panel and located in the immediate vicinity of the latter, the flexible seal 37 then being in eprllt against said panel all along the low cross-section profile 7.

In the lower part, this profile 7 comprises, on the internal side, a hooking return 38 intended to allow the blocking of the chassis relative to the facade profile
F and, on the external side, a seal carrier groove 39 in which is housed the heel of a lip seal 40 which will come to bear against said front profile F.

 In addition, the profile 7 has two cells 41 and 42 which allow said profile to be fixed at its two ends, on the chevron profiles 5 and 6 by means of fixing screws screwed into the friend 27 of said chevron profiles.

 Figure 7 shows in section through a plane A compacting by a line of greatest slope of the roof) a frame 1 mounted. This chassis is hung and locked in the upper part on the wall profile 2 and rests in the lower part on the front profile F by its two chevron profiles 5 and 6. I1 is blocked by two hooking pieces such as 43, which form, each, a hook engaged in the return 38 of the lower cross-section profile 7 and which are fixed to the front profile F. In the example, this profile F is provided with an upper groove and the part 43 is fixed. by means of a screw 44 screwed into a heel 45 housed in said groove; this screw 44, the rod of which passes through a base 43a that the part 43 comprises, makes it possible to fix the latter by tightening.

Figure 8 shows in cross section
BB the juxtaposition of two chassis. The two opposite chevron profiles 5 and 6 of a given chassis are arranged in inverted positions, one with respect to lXautredytrgSvenMuer the contiguous chevron profiles of neighboring salt inverted chassis: the watertight junction of two neighboring chassis is thus achieved by interpenetration of herringbone profiles thereof, the adjustment of the transverse position of the frames consisting simply in sliding them to attach them and obtain this interpenetration.

 Figures 9a, 9b and 9c illustrate the method of de-positioning a frame, a method which requires no drilling and eliminates any delicate adjustment operation.

 The frame considered 1 is presented opposite the wall profile 2 in a roughly horizontal position (FIG. 9a).

 Said chassis is brought closer to this section and slightly raised to allow the attachment of its high cross section 4 to the wall section 2 (FIG. 9b).

 The frame is then inclined downwards until its chevron profiles 5 and 6 come to rest on the front profile F; during this operation, the upper cross section 4 is locked onto the wall profile 2. The lower cross section 7 is then locked relative to the front section F by means of the hooking pieces, by tightening the screws 44.

 We can imagine the great ease of mounting such a roof, which does not require any particular skill or competence. The number of profiles that constitute it is very small and this structural simplicity gives it a moderate price. In addition, a low quality excel seal is obtained without the need for special adjustments, thanks to the various arrangements described.

 Of course, the invention is not limited to the terms of the foregoing description but includes all of its variants.
