Description

The invention relates to the field of sectional doors to erase upwards, such as those typically used for automobile garages.

The invention more particularly relates to such a sectional door - especially a garage door for automobiles - whatever its state (disassembled or pre-mounted or mounted in place on a construction), a panel specifically for such a door sectional and a construction having a bay, provided with such a sectional door.

Such a sectional garage door is already known for a construction having a bay limited by an external front plane and an inner rear plane, vertical and parallel, the spacing corresponding to the thickness of the wall in which the bay is located. Such a bay extends in a longitudinal horizontal direction and a vertical direction. Such a bay also has a median plane of general symmetry, vertical, orthogonal to the outer frontal plane and the inner rear plane. This median plane is also a general plane of symmetry of the door, in reference to the situation where it is mounted in place on the construction, as for example of WO 02/072991 .

There are other areas of application in which sectional closure flaps can be used, for example to close the cargo of a truck, as described in US 6,098, 696 . In this document, a shaft is mounted in a bore of the flap, and a cover is used at this assembly.

For the sake of convenience, throughout the text, the door is described with reference to the state mounted in place on a construction, and more particularly in the closed position. However, such a door can be in the mounted state in place on a construction and in the open position. It can also be in the disassembled or pre-assembled state.

Such a sectional door comprises a frame and an opening.

The frame includes two lateral uprights, to be fixed to the construction, so as to extend in the vertical direction.

Each of these lateral upright assemblies comprises, in the first place, a frontal soul intended to be associated with a spandrel, in particular to be placed against it, to be arranged in a frontal plane which is more or less merged with the inner rear plane of the spine. bay, and to extend also in the longitudinal longitudinal direction. This frontal soul is attached to the median plane, a proximal transverse return. It comprises, secondly, a guide rail which, with respect to the front core, is also arranged in a transverse horizontal direction. It comprises, thirdly, at least one bearing part with which cooperates a holding portion of at least one deformable seal having at least one application portion on the opening. In a known embodiment, the frontal soul is also attached and integral a distal transverse return which, in the closed position, is further from the median plane than the proximal transverse return.

The frame also includes two high side sets, intended to carry the opening in the extreme open position where it is disposed generally horizontally inside the construction, erased in the upper position, to leave the bay free.

The opening comprises, in the first place, a plurality of panels forming together a leaf, extending in the longitudinal horizontal direction, each having an outer front face and an inner rear face. spaced, typically formed by two metal sheets shaped and assembled, and two side edges, two longitudinal edges and a thermally insulating filling. Such a leaf can also be in an extreme position of closure where it is arranged globally vertically to obscure the bay. The opening comprises, secondly, joint hinges of two adjacent panels, axes parallel to the longitudinal longitudinal direction. It comprises, thirdly, two sets of guide rollers carried by the panels to their inner rear faces, protruding from their side edges, axes parallel to the longitudinal longitudinal direction.

Such a sectional door also comprises means for maneuvering and driving the leaf between its two extreme positions.

In the closed position, the outer end faces of the panels - the outer end face of the leaf - extend generally parallel to the outer front plane or to the inner rear plane of the bay, whereas the two sets of guide rollers cooperate with the two guide rails, and a seal application portion is applied to the opening in its lateral areas.

Such a sectional door is described for example in the document EP 0 943 777 .

Such a sectional door with the features of the preamble of claim 1 is described in the document US 6,098,696 .

A panel for such a sectional door with the features of the preamble of claim 9 is described in the document WO 02/072991 A1 .

Such a door is also manufactured and marketed by the company NOVOFERM® under the name ISO 20 for panels with two steel walls, being 20 millimeters thick, and under the mark ISO 45 with panels of 45 millimeters thick , offering better thermal insulation.

A panel has, in cross section relative to its outer front face and its inner rear face, a rectangular or pseudo-rectangular shape with straight side edges, that is to say flat and planes.

According to the embodiments, apart from the possible existence of moldings, cassettes, portholes, gate or the like, the panels forming the leaf are substantially identical or similar to each other, as to their general shape, to their average total thickness, and their relative general arrangement relative to the frame, or different from each other as to their average total thickness.

According to the embodiments, a panel has an outer front face and an inner back face which are flat or substantially flat, the panel then having a total thickness which is the same or substantially the same for the entire panel is a panel has a front face outer and / or an inner back which have substantial reliefs, in particular a panel provided with moldings, cassettes, portholes, gate or the like, the panel having a total thickness that is not the same for the entire panel.

In known manner, the panels have, in horizontal longitudinal direction, a length which, like that of the leaf, is a little larger (for example a few centimeters) than the length of the bay in the same horizontal longitudinal direction. And, in the closed position, the outer end faces of the panels - corresponding to the outer front face of the leaf - are spaced from the frontal plane of the front cores of the frame, towards the interior of the bay and the construction and are therefore clearly separated. from the inner backplane of the bay. This spacing, which is typically of the order of a few centimeters, is in correspondence with the transverse dimension of the proximal transverse return, which is thus visible from the outside. This proximal transverse return terminates opposite the front core by a bearing part with which cooperates a holding portion of the deformable seal having an application portion on the outer end faces of the panels - outer end face of the leaf.

In some cases, it is desired that the sectional door provides some thermal insulation.

This has led manufacturers to offer doors whose panels are thicker, typically 45 millimeters thick.

The document EP 1 359 278 A describes a panel including thermal insulation means.

The document EP 1 571 281 A discloses a sectional door having the general structure discussed above, wherein each side upright assembly is in the form of a profile including a thermal insulation material.

The document EP 2 426 309 A discloses a sectional door having the general structure described above, in which three side seals are provided. Two joints, arranged side by side, are carried by the frontal soul and directed in the transverse direction towards the inside of the sectional door so as to be applied on the outer end faces of the panels - corresponding to the outer front face of the leaf - which are, however, removed from the frontal plane of the frontal souls and clearly separated from the inner rear plane of the bay. Another joint is carried by an additional transverse wing adjoining the front soul and is directed towards the median plane so as to come to apply against the side edges of the panels. Such an embodiment is complex and expensive since it requires three different seals and a side-mounted dormant assembly comprising an additional wing. On the other hand, its effectiveness is limited because the thickness of the panels is itself necessarily limited because, failing that, the total space of the leaf of the sectional door would be excessive.

There is therefore a need to provide an upwardly erasable sectional door, such as that typically used for automobile garages that has improved thermal insulation properties. In addition, it is important that such a door structure and assembly as simple as possible, in any case not more complex than those of current sectional doors. It is also important that such a sectional door is not a substantially higher cost than existing sectional doors. It is also important that such a sectional door offers a perceived high quality in terms of thermal insulation. It is also important that such a sectional door provides a high aesthetic quality, especially that the proximal transverse return is not or is not visible from the outside when the door is in the closed position.

This is the problem underlying the invention.

Hereinafter a detailed discussion of several embodiments of the invention with examples and reference to the drawings.

A sectional door 1, of a type known by the term "upwardly erasable", is adapted and intended to be mounted in place on a construction 2 having a bay 3. The invention is aimed at both the sectional door 1 to the door. Disassembled or pre-assembled state that the sectional door in the state mounted on the construction 2, and that the construction 2 provided with such a door thus mounted.

To simplify the description, it is made with reference to the mounted state of the sectional door 1 in place on the construction 2. It is thus necessary to understand the terms "exterior", "interior", "high" "," Down "," vertical "," horizontal "," front "," rear ". Of course, the sectional door 1 in the disassembled or pre-assembled state can be in any relative position.

The construction 2 comprises a wall 4 in which is formed the bay 3 with, on either side laterally, two kinds of piers 5 - or songs between the outer face 4a and the inner face 4b of the wall 4 - and in the upper part a lintel. Such a bay 3 is limited by an outer front plane Pfe and an inner rear plane Pai, corresponding respectively to the outer face 4a and the inner face 4b of the wall 4. The Pfe and Pai planes are parallel to each other and to the wall 4, and arranged vertically. They are spaced a distance corresponding to the thickness of the wall 4. The bay 3 extends in a longitudinal horizontal direction H and a vertical direction V. In addition, the bay 3 has a median plane of general symmetry, vertical , Pms. Taking into account the convention previously indicated with regard to the description of the sectional door 1, this one also comprises a median plane of general symmetry, Pms. On either side of the bay 3, laterally, towards the interior I of the building 2, are the two spandrels 4c.

Is called "side", which is on the side of the sectional door 1 or the bay 3, that is to say on either side.
Direction H is termed "longitudinal" because it extends along Bay 3.
The Pfe plane is termed "external frontal" because it is placed forward, frontally, and on the outer side E of the building 2. Conversely, the plane Pfe is described as "inside back" because it is placed rearward with respect to the plane Pfe, and the inner side I of the construction 2.
The horizontal direction orthogonal to the longitudinal horizontal direction is referred to as the "transverse horizontal direction T". By analogy, a vertical plane orthogonal to the external frontal plane Pfe and to the inner rear plane Pai is called a "transverse plane Pt". Thus, the piers or songs 5 of the bay 3 are arranged transversely, in addition to vertically.

It is understood that the terms "horizontal", "vertical", "orthogonal" should be understood as also including what is substantially horizontal, substantially vertical, substantially orthogonal.

The sectional door 1 comprises a frame 6 and an opening 7.

The frame 6 comprises on the one hand two sets called "side uprights" 6a, intended to be fixed to the spandrels 4c, so as to extend in the vertical direction V and, secondly, two sets, called "lateral highs" 6b. The two lateral upright assemblies 6a are intended to carry, position, and guide the opening 7 in the closed position or for its portion disposed generally vertically, while the two upper lateral assemblies 6b are intended to carry, position, and guide the opening 7 in the open position or for its portion disposed in the upper position generally horizontally.

Each side upright assembly 6a comprises firstly a front core 8 intended to be associated, in particular to be placed against, possibly rigidly attached to a spandrel 4c. In the embodiment shown, the lateral upright assembly 6a is a folded metal sheet. The frontal soul 8 extends in a front plane Pai 'confused with the inner rear plane Pai of the bay 3. In other embodiments, the two planes Pai and Pai' can be distinct while remaining adjacent, with a spacing lower, for example, less than one centimeter.

To the front core 8 is attached and integral a transverse return 8a described as "proximal" because it is closest to the opening 7 and the median plane Pms that another transverse return 8c qualified as opposed to "distal Which is also contiguous and integral with the front core 8, but, considered in horizontal longitudinal direction H, is spaced laterally from the proximal transverse return 8a. The front core 8, the return 8a and the return 8c together form a generally U-shaped profile, whose branch corresponding to the proximal transverse return 8a is of smaller length, considered in the transverse direction T, while the branch corresponding to the distal transverse return 8c is of greater length, considered in transverse direction T.

Each lateral upright assembly 6a also comprises a guide rail 9 which, with respect to the front core 8, is also arranged in a transverse horizontal direction T. In the embodiment shown, the guide rail 9 is attached to and integral with the return distal transverse 8c opposite the frontal soul 8.

Each lateral upright frame 6a also comprises at least one bearing part 8b with which a holding part 10a of at least one deformable seal 10 having at least one application part 10b on the opening 7 cooperates. seals 10 arranged laterally, for thermal insulation (avoiding the passage of air), but also protection against rain, sound insulation. These seals 10 also contribute to the aesthetics of the sectional door 1 by establishing a visual continuity between the frame 6 and the leaf 11a. When the leaf 11a is moved between its two extreme positions, respectively opening and closing, the panels 11 slide on the two joints 10. In the embodiment shown, the proximal transverse return 8a comprises, towards the opposite of the soul frontal 8, at its end, a bearing portion 8b seal.

A seal 10 has a holding portion 10a, an application portion 10b and between them a seal body 10c.

The opening 7 comprises a plurality of panels 11, rigid and self-supporting, following an extension of each other, associated with each other adjacent, so as to form a leaf 11a, continuous. Thus, in the embodiment shown on the figure 1 , the leaf 11a comprises four panels 11, this number of panels being only exemplary. The prediction of four panels, or a nearby number of panels, is typical in the case of automobile garage doors. Each panel 11 extends in its largest dimension in the longitudinal horizontal direction H. Each panel 11 has an outer end face 12a and an inner back face 12b formed by two metal sheets, for example painted galvanized steel, shaped and assembled, directly or indirectly, extending generally parallel to each other for their main portions. The two faces, outer front 12a and inner rear 12b, are arranged spaced apart from each other. Each panel 11 also has two side edges 13 and two longitudinal edges 14a and 14b, low and high, respectively. According to the embodiments, the side edges 13 are formed by a portion of one and / or the other of the two metal sheets also forming the outer end face 12a and the inner rear face 12b of the panel or by two shaped sheets or two profiles, for example metal, reported, as shown on the Figures 3A, 3B , 4A, 4B and 5A to 5E . Each panel 11 also has an internal hollow space for filling 15, thermal insulation, between the shaped and assembled metal sheets forming the faces 12a and 12b. By convention, the terms "external front face 12a", "internal rear face 12b" and "side edges 13" are applied both for a panel 11 and for all the panels 11 forming the leaf 11a. The longitudinal edges 14a and 14b, low and high, respectively, are shaped with a complementary projection and recess so that two successive panels 11 can be adjacent while being relatively pivotable relative to each other. The case Where appropriate, the bottom longitudinal edge 14a of the lowest panel 11 and the high longitudinal edge 14b of the uppermost panel 11, which are free, may have a special arrangement, such as a seal, contact bar, etc.

The opening 7, especially the leaf 11a, can be in two extreme positions, respectively opening and closing, and be operated and driven between these two positions. In the open position, the leaf 11a is disposed generally horizontally inside the construction 2, erased in the high position, carried by the two upper side assemblies 6b with rails (carried by the ceiling 4d for example by means of supports 6d ), to leave free the bay 3. In the closed position, the leaf 11a is arranged generally vertically to obscure the bay 3, being then carried by the two side upright assemblies 6a. Of course, the opening 7, especially the leaf 11a, is dimensioned in relation to the bay 3 while the frame 6 is dimensioned in relation to the opening 7. In the case of a garage door for automobiles, the bay 3 may have, typically, a length, considered in horizontal longitudinal direction H, which may be between the order of 2 meters or a little less and of the order of 5 meters or a little more. The bay 3 may have, typically, a height, considered in vertical direction V, which may be between the order of 2 meters or slightly less and of the order of 2.5 meters. As a result, a panel 11 may have a length, considered in longitudinal horizontal direction H, between its two side edges 13, which may be between about 2 meters or slightly less and about 5 meters or a little more and a height, considered in vertical direction V, between its two longitudinal edges 14a and 14b which can be of the order of 50 centimeters. These dimensions are illustrative but not limiting.

The opening 7 also has hinges of association of two adjacent panels 11, axes parallel to the longitudinal horizontal direction H.

The opening 7 also comprises two sets of guide rollers 16, carried by the panels 11 to their inner rear faces 12b projecting from their side edges 13, axes parallel to the longitudinal horizontal direction.

The sectional door 1 also comprises means for maneuvering and driving the leaf 11a between its two extreme positions. These means are manual or motorized, if necessary remote controlled.

With such a sectional door, in the closed position, the outer end faces 12a of the panels 11 - outer end face 12a of the leaf 11a - extend generally parallel to the outer front plane Pfe and the inner rear plane Pai of the bay 3,, considered in the longitudinal horizontal direction H, the side edges 13 of the panels 11 - side edges 13 of the leaf 11a - are spaced from the distal transverse returns 8c, while the two sets of guide rollers 16 cooperate with the two guide rails 9, and that each seal 10 is applied to the panels 11 and the leaf 11a, in its lateral areas.

In the embodiment shown on the figure 1 , apart from the possible existence of moldings, cassettes, portholes, wicket or the like, the panels 11 forming the leaf 11a are substantially identical or similar to each other, as to their general form, as to their relative general arrangement with respect to the 6, and their average total thickness, measured in the transverse direction T while the door is in the closed position. The description is made more particularly with reference to such an embodiment which, however, is not exclusive of others in which, apart from the possible existence of moldings, cassettes, portholes, gate or the like, the panels 11 forming the leaf 11a are substantially different from each other, for example as to their average total thickness.

Moreover, in the embodiment shown on the figure 2 , apart from the possible existence of moldings, cassettes, the panels 11 and the leaf 11a are arranged so as to be symmetrical with respect to the median plane Pms. The description is made more specifically with reference to such an embodiment which, however, is not exclusive of others in which the panels 11 and the leaf 11a are not symmetrical with respect to the median plane Pms.

Considered in the transverse direction T and in the closed position, a panel 11 comprises - and more particularly a panel 11 is constituted by - a front portion 17a adjacent to its outer end face 12a and a rear portion 17b adjacent to its inner rear face 12b. This rear portion 17b has, with respect to the front portion 17a, at least one lateral extension 18 extending in the longitudinal horizontal direction H, and more particularly this rear portion 17b has two lateral extensions 18, on either side. , especially identical or similar, in particular of the same dimension in the longitudinal horizontal direction.

As a result, considered in longitudinal longitudinal direction, the rear portion 17b has a length greater than the length of the front portion 17a. And, a side edge 13 having a lateral extension 18 forms a rabbet 19 open frontally and laterally. This rabbet 19 has a transverse portion 19a laterally limiting the front portion 17a and a longitudinal portion 19b frontally limiting the extension 18.

The total thickness of such a panel 11 is the sum of the thickness of its front portion 17a and the thickness of its rear portion 17b.

Such a panel 11 has, in cross section relative to its outer end face 12a and its inner rear face 12b (plane of figures 2 , 3A , 3B , 4A , 4B , 5A to 5E ), a shape that is the combination of a rectangular or pseudo-rectangular shape corresponding to its front portion 17a and a rectangular or pseudo-rectangular shape corresponding to its rear portion 17b, these two rectangular or pseudo-rectangular shapes being adjacent and arranged with a general symmetry with respect to the median plane Pms of the panel 11.

In the closed position, considered in the longitudinal horizontal direction H, the front portion 17a of the panel 11 is entirely located between the two lateral upright assemblies 6a and extends to their vicinity. More specifically, the lateral edge 13 of the front portion 17a is disposed, considered in the longitudinal horizontal direction H, in the vicinity of the proximal transverse return 8a, with a small joint passage space 10. "Neighborhood" must be understood here as meaning a small distance so as to limit the passage of air, but sufficient for the leaf 11a can move relative to the two side uprights 6a without rubbing on those and that the seal 10 can be put in place between them. Such a distance is of the order of a few millimeters or of the order of a centimeter.

In the closed position, considered in the transverse direction T, the outer end face 12a of the panel 11 is disposed in the vicinity of the front plane Pai 'of the front webs 8. "Neighborhood" must be understood here to mean that the outer front face 12a of the panel 11 is spaced from the frontal plane Pai 'frontal webs 8 with an average distance of less than 1 centimeter, more particularly less than 0.5 centimeter. And, also in the closed position, and considered in the transverse direction T, the outer end face 12a of the panel 11 is disposed in the, or in the vicinity of, the inner rear plane Pai of the bay 3. Being reminded that the front plane Pai 'is merged with the inner Pai backplane or the two separate planes are adjacent, with little spacing between them. Thus, in the closed position, the returns transversal transverse 8a are substantially invisible from the outside of the sectional door 1 and the construction 2.

In the closed position, the seal 10 is applied, by its application portion 10b, on the front portion 17a of the panel 11. More specifically, the application portion 10b is arranged, considered in the transverse direction T, in the , or in the vicinity of the front plane Pai 'of the front core 8, respectively of the inner rear plane Pai of the bay 3, and, in the closed position, it is applied on the outer end face 12a of the panel 11.

The invention relates to an embodiment in which a panel 11 has the characteristics described. It also relates to the embodiments in which several panels 11, in particular the majority of the panels 11 of the leaf 11a, and more especially the whole (as in the case of the figure 1 ) or almost all of the panels 11 of the leaf 11a, have the characteristics described.

In addition, apart from the possible existence of moldings, cassettes, portholes, gate or the like, a panel 11 has a total average thickness D - between its outer end face 12a and its inner rear face 12b - which is greater than 45 millimeters (which is the largest standard thickness of sectional door panels to date), in particular an average total thickness D between 45 millimeters and 65 millimeters, more especially a total average thickness D equal to or in the order of 60 millimeters.

The seal body 10c extends in the transverse direction T and comes against the proximal transverse return 8a. The application part 10b and the body 10c then form between them an angle of the order of a right angle, while the application part 10b and the holding part 10a are arranged on either side of the body 10c.

The seal 10 may be the subject of different embodiments.

In a first realization ( figures 2 , 3A and 3B ), the seal body 10c extends a substantial length in the transverse direction T and the holding portion 10a is disposed against the body 10c by means of a bend at a 360 ° angle. In a second realization ( Figures 4A and 4B ), the body of the seal 10c extends over a short length in the transverse direction T and the holding portion 10a forms with the body 10c an angle of the order of a right angle.

In another aspect, it is possible to envisage, as represented on the Figures 3A and 3B , a seal 10 having an application portion 10d which, considered in the transverse direction T, is spaced inwards relative to the front plane Pai 'of the front core 8, respectively relative to the interior rear plane Pai of the bay 3, and which, in the closed position, is applied on the rear portion 17b or the rabbet 19 of the panel 11, in particular its longitudinal portion 19b.

In this case, it is possible to envisage, as represented on the Figures 3A and 3B , that the same seal 10 has a first application portion 10b on the front portion 17a of the panel 11, especially the outer end face 12a, and a second application portion 10d on the rear portion 17b or the rebate 19 of the panel 11, in particular its longitudinal part 19b.

It is also possible to envisage, in another embodiment, that there are two separate seals, a first seal 10 having an application portion 10b on the front portion 17a of the panel 11 and a second seal having a portion of application 10b on the rear portion 17b or the rabbet 19 of the panel 11.

The achievements just described are not exclusive of others, functionally equivalent.

More specifically, other constructive features of a specially adapted panel 11 for the sectional door 1 are now more specifically described.

The panel 11 may be the subject of different embodiments.

Thus, according to one conceivable embodiment, a panel 11 has an outer front face 12a and an inner rear face 12b which are flat or substantially flat. In this case, the panel 11 has a total thickness that is the same or substantially the same for the entire panel 11. If all the panels 11 of the leaf 11a are identical or similar and in particular are of the same thickness, the leaf 11a itself even an outer front face 12a and an inner rear face 12b which are flat or substantially flat and a total thickness which is the same or substantially the same for all the leaf 11a, with the possible exception of longitudinal edge areas 14a, 14b.

According to another conceivable embodiment, a panel 11 has an outer end face 12a and / or an inner rear face 12b which have substantial reliefs, recessed and / or protruding. Such is for example the case of a panel 11 provided with moldings, cassettes, portholes, gate or the like. In this case, the panel 11 has a total thickness that is not the same for the entire panel 11.

According to possible embodiments, the rear portion 17b of the panel 11 has an average thickness greater than the average thickness of its front portion 17a. In particular, the rear portion 17b has an average thickness greater than half the average total thickness D of the panel 11. In particular, the rear portion 17b has an average thickness of the order of 2/3 or 3 / 4 of the total average thickness D of the panel 11. Thus, with a panel 11 having a total average thickness of 60 millimeters, it can be envisaged that the front portion 17a has a thickness of the order of 20 millimeters while the rear part has a thickness of the order of 20 millimeters.

In one conceivable embodiment, a lateral extension 18 has a dimension in longitudinal horizontal direction H of the same order of magnitude as the average total thickness D of the panel 11. In particular, this dimension of the lateral extension 18 may be of the order of a fraction the average total thickness D of the panel 11, as of the order 1/3. Such an embodiment is given by way of example.

In one possible embodiment, a lateral extension 18 has a dimension in horizontal longitudinal direction H of the order of a few millimeters to a few centimeters.

What has been described for a panel 11 may be transposed to the leaf 11a in that it comprises this panel or leaf 11a in its entirety if the panels 11 are identical or similar.

The panel 11 comprises two shaped and assembled metal sheets forming the outer end face 12a and the inner rear face 12b and an inner hollow space for the thermal insulating filling 15. According to embodiments, the front portion 17a and the rear portion 17b form, each on the one hand, together on the other hand, a single continuous hollow space or several distinct hollow spaces, filling 15 occupying all or only part of one or more of these hollow spaces.

Thus, in the embodiment shown on the Figures 3A, 3B , 4A and 4B , the front part 17a and the rear part 17b together form a single continuous hollow space, filling 15 occupying the entire hollow space.

In the embodiment shown on the Figure 5A , the front portion 17a and the rear portion 17b each form a single continuous hollow space, the panel 11 thus having two continuous but distinct hollow spaces, one 20a for the front portion 17a and the other 20b for the rear portion 17b.And filling 15 occupies all of these two hollow spaces. Such an embodiment may be suitable with front portions 17a and 17b rear made separately and rigidly associated with each other, then.

In the embodiment shown on the Figure 5B , the front part 17a and the rear part 17b, with the exception of the lateral extensions 18, together form a single continuous hollow space 21a, while the two lateral extensions 18 form two distinct hollow spaces 21b. And, the filling 15 occupies the entire hollow space formed by the front portion 17a and the portion of the rear portion 17b which extends, while the two hollow spaces of the two lateral extensions 18 are free of filling. Such an embodiment may be suitable with lateral extensions 18 reported.

The realization of the Figure 5C is similar to that of Figures 3A, 3B , 4A and 4B except that the front portion 17a has a smaller thickness and the rear portion 17b a greater thickness, all other things being equal, and that the panel 11 is provided to include an additional stiffening structure 22, arranged in the panel 11.

The realization of the figure 5D is a variant of the realization of the Figure 5A with a filling of the hollow space 20b of the rear portion 17b with a composite filling comprising for example several layers 15a, 15b, 15c, 15d and 15e.

The realization of the figure 5E is a variant of the realization of the Figures 3A, 3B , 4A and 4B with an outer front face 12a comprising a portion 23 in relief, here hollow on a small portion of the thickness of the front portion 17a, but can be projecting and of various shape.

Filling 15 provides thermal insulation. According to the invention it is a material such as a rigid plastic foam. It may also be a different structure, more or less complex, homogeneous or not, for example in layers or cells or anything else, or an insulation device. The expression "filling, thermal insulation" refers to all these achievements and all those that are functionally equivalent.

According to the invention the filling 15 is placed in the hollow space or spaces of the front part 17a and the rear part 17b. According to the embodiments, as stated above, it occupies all or only part of this or these hollow spaces.

The achievements just described are not exclusive to others. They illustrate the versatility of form, arrangement and structure of a panel 11.

The invention also relates to the construction 2 equipped with the sectional door 1.

This construction 2 has already been described. It has a 3 bay limited by the two outer Pfe front planes and inner rear Pai. It is equipped with a sectional door 1, especially garage door for automobiles, the two side upright assemblies 6a are attached to the construction 2, the front core 8 of each of them being associated with a wedge 4c, disposed in the frontal plane Pai '.

In the extreme open position, the leaf 11a is disposed generally horizontally inside I of the construction 2, erased in the high position, to leave free the bay 3, carried by the upper side assemblies 6b.

In the extreme closed position, the leaf 11a is arranged vertically vertically to conceal the bay 3. In this position, the outer end face 12a of the panel (s) 11 - outer end face 12a of the leaf 11a - extends generally parallel to the planes Pfe outside front and Pai inner rear, while, considered in the longitudinal horizontal direction H, the front portion 17a of the panel (s) 11 - front portion 17a of the leaf 11a - is entirely located between the two lateral upright assemblies 6a while extending to their vicinity and that, considered in the transverse direction T, the outer end face 12a of the panel (s) 11 - outer end face 12a of the leaf 11a - is disposed in the or in the vicinity of the inner rear plane Pai of the bay 3, being separated from it by an average distance of less than 1 centimeter, more particularly less than 0.5 centimeter.

As indicated, the frame 6 includes two lateral upright assemblies 6a each comprising a proximal transverse return 8a which, in the closed position, is substantially invisible from the outside E of the sectional door 1 and the construction 2.
