Description

Technical field

[0001] The present invention relates to the field of lightweight constructions, in particular garden pergolas. Prior art

[0002] Such constructions usually feature beams with exposed edges. In addition, it is known to have slats protruding in height when the pergola is viewed from the side.

[0003] There is a need to further improve the appearance and aesthetics of such lightweight constructions, while giving them at least equivalent, or even improved, qualities of service life.

[0004] Furthermore, there is a need to facilitate the design and assembly of such a lightweight construction, and to allow its adaptability to any space intended to accommodate it. Statement of the invention

[0005] The invention aims to meet all or part of these needs and achieves this, according to one of its aspects, by means of a lightweight construction element, in particular a pergola, comprising a support structure and slats carried by the support structure, the support structure comprising: at least one post, at least one supporting beam, at least one overbeam of generally elongated shape attached to the supporting beam, the overbeam having at least one closed contour cross-section.

[0006] Such a building element can be lighter, therefore easier to transport, assemble and disassemble, while being stronger and more resistant. The building element according to the invention is easy to install and does not require any specialized labor. Summary of the invention Load-bearing beam

[0007] A beam is a building part of a generally elongated shape. A load-bearing beam is a beam intended to extend horizontally, being carried by one or more posts, perpendicular to them.

[0008] The supporting structure may comprise one or two supporting beams, or even more than two supporting beams, in particular an even number of supporting beams.

[0009] The supporting beam may be hollow, in particular over a portion of length greater than a third of the length of said supporting beam, or even at least half, or even at least two-thirds, or even at least three-quarters of the length of said supporting beam, being substantially equal to the length of said supporting beam.

[0010] The supporting beam may have a general shape symmetrical with respect to a median plane. The median plane may be parallel to a longitudinal axis of said supporting beam, extending in particular vertically.

[0011] The supporting beam may have a generally rectangular cross-section. The supporting beam may have a first wall and a second wall. When the supporting beam is mounted on the support structure, the first wall may be located on the inner side of the support structure, and the second wall may be located on the outer side of the support structure.

[0012] The load-bearing beam may have a top wall and a bottom wall.

[0013] The upper wall of the supporting beam may be intended to receive the overbeam. Alternatively, the supporting beam may have no upper wall.

[0014] The supporting beam may comprise a plurality of fixing holes passing through the first wall. Said fixing holes may be distributed along an axis parallel to the longitudinal axis of said supporting beam, in particular being uniformly distributed. The fixing holes may be uniformly distributed along the length of the first wall of the supporting beam.

[0015] The fixing holes may be configured to receive end caps of the blades. The end caps may extend between the first and second walls of the supporting beam.

[0016] The load-bearing beam may have a horizontal partition. The horizontal partition may extend over at least a portion of the length of said load-bearing beam. The horizontal partition may connect the second outer wall to the first inner wall of said load-bearing beam.

[0017] The supporting beam may include a gutter for receiving and draining precipitation. In one embodiment, precipitation received in the gutter of the supporting beam may be discharged into the column.

[0018] The supporting beam may have a rib extending over at least a portion of the length of the supporting beam. The rib may be configured to cooperate with a profile for attaching the overbeam. In particular, the overbeam may slide along the supporting beam, in particular along an axis parallel to the rib.

[0019] Alternatively, the supporting beam may have a groove extending over at least a portion of the length of the supporting beam. The groove may be configured to cooperate with the attachment profile of the overbeam.

[0020] The supporting beam may be fixed to the post by fastening means, in particular by screwing. The supporting beam may be partially fitted into a socket portion of the post. Alternatively or additionally, the supporting beam may be fixed to a wall, in particular by screwing.

[0021] The length of the supporting beam can be between 1.5 and 5 m, better between 1.7 and 4 m, being in particular of the order of 3 m.

[0022] The supporting beam can be made at least partially of metal, in particular aluminum. Overbeam

[0023] The term "overbeam" refers to a construction part of generally elongated shape, intended to be mounted above a beam.

[0024] Thanks to the overbeam according to the invention, the beams on which an overbeam is attached are completely or partially concealed when the support structure is viewed from above. This results in an aesthetic gain. In addition, the slats are concealed when the support structure is viewed from the side. This results in an aesthetic gain.

[0025] By "added overbeam", it is meant that the overbeam is added to the supporting beam during assembly, the overbeam and the supporting beam being two separate parts.

[0026] The overbeam may have a general shape symmetrical with respect to a median plane. The median plane may be parallel to a longitudinal axis of the overbeam, in particular extending vertically.

[0027] The "cross-section" of the overbeam refers to the section obtained by cutting the overbeam along a plane perpendicular to its axis of elongation, also called the longitudinal axis of the overbeam.

[0028] The overbeam may have a closed contour cross-section over at least 10% of its length, better still at least 25%, even better still at least 50%, or even at least 75%, even better still at least 90% of its length. The overbeam may have a closed contour cross-section over its entire length. A closed cross-section makes it possible to obtain a more robust overbeam, with better mechanical strength.

[0029] The overbeam may have a generally cylindrical shape. By "cylindrical shape" we mean a ruled surface shape whose generating lines are parallel, that is to say having a surface in space formed of lines parallel to each other.

[0030] The overbeam may have a polygonal cross-section, including rectangular or square, triangular, pentagonal, hexagonal or even octagonal. In particular, the overbeam may define four rectangular walls. Alternatively, the overbeam may have an elliptical or even circular cross-section.

[0031] The overbeam may be hollow. In one embodiment, the overbeam may have a cavity. The cavity may be open.

[0032] The overbeam may have an open cavity at at least one end of the overbeam. An open cavity means that the overbeam has an opening directly connected to the outside. An overbeam that defines a cavity in this way provides a space protected from precipitation, rain and / or wind.

[0033] The cavity can accommodate a functional device. Various functional devices, such as a misting system, a lighting system, or a sound system, can be installed inside the cavity and form a compact unit. This saves space. The overbeam also provides impact protection for any functional devices housed inside.

[0034] The cavity may extend over at least 10%, better still at least 25%, even better at least 50%, or even at least 75%, even better at least 90% of the length of the overbeam. The cavity may extend over the entire length of the overbeam.

[0035] The overbeam can define a single open cavity communicating with the exterior at each of its ends, or several.

[0036] The overbeam may have two separate cavities, each open at both ends of said overbeam. Said cavities may be separated by a partition provided within the overbeam. The partition may extend in a plane parallel to the longitudinal axis of the overbeam, in particular a horizontal plane. By “horizontal plane” is meant a plane parallel to the ground when the support structure is mounted. Alternatively, the partition may extend in a plane transverse to the longitudinal axis of the overbeam.

[0037] The overbeam may be removable. By "removable overbeam" it is meant that the overbeam can be removed from the support structure, being able to be dismantled and / or reassembled, without it being necessary to dismantle the rest of said support structure. A removable overbeam allows for rapid assembly and disassembly. The overbeam can be assembled and dismantled several times. In particular, the overbeam can be removed without irreversible mechanical deformation of it or of the support structure. Its replacement is thus simplified.

[0038] The overbeam can be clipped onto the supporting beam. A clip-on fastening system allows for simplified assembly and disassembly of the construction element. In particular, the overbeam can be replaced relatively easily.

[0039] The overbeam may comprise at least one fixing profile extending along one of its walls along a longitudinal axis of said overbeam.

[0040] The fixing profile may be straight. The fixing profile may extend over at least 10%, better still at least 25%, or even at least 50%, or even at least 75%, or even at least 90% of the length of the overbeam. The fixing profile may extend over the entire length of the overbeam.

[0041] In one embodiment, the overbeam comprises two substantially identical fixing profiles, in particular arranged symmetrically along a median plane parallel to the longitudinal axis of said overbeam, in particular a vertical median plane.

[0042] The fixing profile may comprise a rib. The rib may extend longitudinally along the fixing profile. In particular, the rib may extend parallel to the longitudinal axis of the overbeam. The rib may extend over at least 10%, better still at least 25%, or even at least 50%, or even at least 75%, or even at least 90% of the length of the fixing profile.

[0043] The rib may be located at a distal end of the fixing profile. The rib of the fixing profile of the overbeam may cooperate with the groove or the rib of the supporting beam, in particular by clipping.

[0044] The overbeam can slide along the supporting beam.

[0045] The overbeam may have through holes arranged along at least one of its walls, in particular along one of its walls. The term "through hole" refers to an opening made through one of the walls of the overbeam. The overbeam may have through holes arranged along at least two walls, in particular along two walls, or even three walls, or even four walls.

[0046] The through holes may be arranged symmetrically along a median plane of the overbeam, the median plane extending in particular parallel to the longitudinal axis of the overbeam.

[0047] The number of through holes can be between 2 and 200, better between 3 and 100, or even between 3 and 50, or even between 5 and 50, or even between 10 and 50.

[0048] The through holes may be polygonal in shape, such as square or rectangular, or pentagonal, hexagonal or octagonal. Alternatively, the through holes may be circular in shape.

[0049] The through holes can be larger, between 1 and 100 mm, better between 2 and 50 mm, or even between 5 and 30 mm.

[0050] The through holes may be identical. Alternatively, the through holes may have at least two different shapes, or even at least three different shapes, or even more than four different shapes.

[0051] The through holes may be aligned along at least one row of holes, including one row, or even two or three rows, or even more than four rows. A row of holes may be parallel to the longitudinal axis of the overbeam. The row of holes may extend over at least 10% of the length of the overbeam, more preferably at least 25%, even more preferably at least 50%, or even at least 75%, even more preferably at least 90% of its length. The through holes of said at least one row may be uniformly spaced.

[0052] The overbeam may have at least one closing hood at one of its ends, in particular two closing hoods arranged at each of the ends of said overbeam.

[0053] The length of the overbeam can be between 0.5 and 5 m, better between 1.5 and 4 m, being in particular of the order of 3 m.

[0054] The cross-sectional area of ​​the cavity can be between 100 and 40000 mm 2< , better between 500 and 5000 mm 2< . Such dimensions allow for both a relatively small footprint and an internal cavity of sufficient size to accommodate different types of devices.

[0055] The overbeam can be made at least partially of metal, particularly aluminum. Auxiliary beam

[0056] The support structure may comprise at least one auxiliary beam transverse to the load-bearing beam, in particular perpendicular to the latter, at least one overbeam of generally elongated shape which may in particular be attached to the auxiliary beam, the overbeam having in particular at least one closed contour cross-section.

[0057] The support structure may comprise two or more auxiliary beams, including an even number of auxiliary beams.

[0058] The auxiliary beam(s) may extend parallel to the blades.

[0059] The auxiliary beam(s) may have all or part of the characteristics of the load-bearing beam(s) mentioned above with reference to the load-bearing beam. In particular, the auxiliary beam may be hollow, in particular over a portion of length substantially equal to the length of said auxiliary beam, or even at least half, or even at least two-thirds, or even at least three-quarters of the length of said auxiliary beam, being substantially equal to the length of said auxiliary beam.

[0060] The auxiliary beam may have a general shape symmetrical with respect to a median plane. The median plane may be parallel to a longitudinal axis of said supporting beam, extending in particular vertically.

[0061] The auxiliary beam may have a generally rectangular shape, with a first wall and a second wall. When the auxiliary beam is mounted on the support structure, the first wall is located on the innermost side of said support structure, and the second wall is located on the outermost side of said support structure.

[0062] The auxiliary beam may have a top wall and a bottom wall. The top wall may be intended to receive the overbeam. Alternatively, the auxiliary beam may have no top wall.

[0063] The auxiliary beam may have a horizontal partition. The horizontal partition may extend over at least a portion of the length of said auxiliary beam. The horizontal partition may connect the second outer wall to the first inner wall of said auxiliary beam.

[0064] The auxiliary beam may include a gutter for receiving and draining precipitation. In one embodiment, precipitation received in the gutter of the auxiliary beam may be discharged inside the column.

[0065] The auxiliary beam may have a rib extending over at least part of the length of the supporting beam. The rib may be configured to cooperate with a fixing profile of the overbeam. In particular, the overbeam may slide along the supporting beam, in particular along an axis parallel to the rib.

[0066] Alternatively, the auxiliary beam may have a groove extending over at least a portion of the length of the auxiliary beam. The groove may be configured to cooperate with the attachment profile of the overbeam.

[0067] The auxiliary beam may be fixed to the post by fastening means, in particular by screwing. The auxiliary beam may be partially fitted into a socket portion of the post. Alternatively or additionally, the auxiliary beam may be fixed to a wall, in particular by screwing.

[0068] The length of the auxiliary beam can be between 1.5 and 5 m, better between 1.7 and 4 m, being in particular of the order of 3 m.

[0069] The auxiliary beam can be made at least partially of metal, in particular aluminum. Blades

[0070] The lightweight construction element may comprise a plurality of blades. The support structure may comprise a row of blades, in particular between 2 and 100, better still between 5 and 50, even better still between 8 and 20 blades.

[0071] The blades may be arranged parallel side by side. Hereinafter, the term "axis of the blades" refers to the common axis of parallelism of the blades. In particular, the axis of the blades may be perpendicular to the axis of elongation of the at least one overbeam, in particular attached to the at least one supporting beam.

[0072] The blades may be fixed at their end(s) to at least one supporting beam, preferably at least two supporting beams, transversely to these. The blades may be mounted freely rotatable about an axis parallel to the axis of the blades.

[0073] The blades can have a generally rectangular shape, and define two main faces. The main faces can be rectangular.

[0074] The blades may define two lateral faces perpendicular to the main faces, in particular opposite the at least one supporting beam. The lateral faces may be trapezoidal in shape, in particular rectangular.

[0076] The blades may be configured to be movable between an open position and a closed position. In the open position, the blades may be vertical, at least one of the main faces of the blades being perpendicular to the ground, or oblique. In the closed position, the blades may be horizontal, at least one of the main faces of the blades being parallel to the ground. In particular, precipitation may be blocked by one of the two main faces of each of the blades.

[0077] The blades may be flat. In particular, the blades may have a single wall of generally rectangular shape. Alternatively, the blades may have a curved portion.

[0078] Each of the blades may have a first profile in the form of a gutter. The first profile may act as a gutter.

[0148] It has been illustrated to the figures 1 to 10 a light construction element 1, in particular a pergola, comprising a support structure 2 and blades 8 carried by the support structure 2. The support structure 2 has a generally rectangular shape when viewed from above.

[0149] In the illustrated embodiment, the support structure 2 comprises four posts 3, two load-bearing beams 4 and two auxiliary beams 6.

[0150] The support structure 2 is made partially of metal, in particular entirely of metal.

[0151] Each supporting beam 4 and auxiliary beam 6 has an overbeam 10. The overbeam 10 has a length substantially equal to that of the supporting beams 4 and the auxiliary beams 6.

[0152] The supporting beam 4 is hollow along its entire length.

[0153] The supporting beam 4 has a general shape symmetrical with respect to a median plane parallel to a longitudinal axis of said supporting beam 4, extending in particular vertically.

[0154] The supporting beam 4 has a generally rectangular cross-section. The supporting beam 4 comprises a first wall 42 and a second wall 44. The first wall 42 is located on the inner side of the supporting structure 2, and the second wall 44 is located on the outer side of the supporting structure 2.

[0155] The supporting beam 4 has no upper wall.

[0156] As illustrated in figures 6 And 8 à 10 , the supporting beam 4 comprises a plurality of fixing holes 18 passing through the first wall. Said fixing holes 18 are uniformly distributed along an axis parallel to the longitudinal axis of said supporting beam 4. The fixing holes 18 are configured to receive the end pieces 32 of the blades 8. The end pieces 32 extend between the two first 42 and second 44 walls of the supporting beam.

[0157] The supporting beam 4 comprises a gutter 40 intended to receive and evacuate precipitation. The precipitation received in the gutter 40 of the supporting beam 4 is discharged inside the column 3.

[0158] The supporting beam 4 is fixed to the post 3 by fixing means 52, 54, in particular by screwing. The supporting beam 4 is fitted into a fitting portion 58 of the post.

[0159] The length of the supporting beam 4 is about 3 m. The supporting beam 4 is made of aluminum.

[0160] As visible on the figures 4 And 5 , the supporting beam has a horizontal partition 46. The horizontal partition 46 extends over the entire length of said supporting beam. The horizontal partition 46 connects the second outer wall 44 to the first inner wall 38 of said supporting beam 4.

[0161] The supporting beam 4 has a rib 48. The rib 48 extends over the entire length of the supporting beam 4. The rib 48 is configured to cooperate with a fixing profile 28 of the overbeam 10.

[0162] The overbeam 10 is of generally elongated shape. The overbeam 10 has a closed contour cross-section along its entire length. The overbeam 10 has a generally symmetrical shape with respect to a median plane. The median plane is parallel to a longitudinal axis of the overbeam 10, and extends in particular vertically. The overbeam 10 has a generally cylindrical shape. The overbeam 10 has a square cross-section. In particular, the overbeam 10 defines four rectangular walls.

[0163] The overbeam 10 is hollow. The overbeam 10 defines a single open cavity 22 communicating with the exterior at each of its ends. The cavity 22 extends over the entire length of the overbeam 10.

[0164] The overbeam 10 is removable. The overbeam 10 is clipped onto the supporting beam 4 on the Figure 5 .

[0165] The overbeam comprises two fixing profiles 28. The two fixing profiles 28 are substantially identical. Said fixing profiles 28 are arranged symmetrically along a vertical median plane parallel to the longitudinal axis of said overbeam 10. The fixing profiles 28 extend along one of the lower wall 26 of the overbeam. Said profiles extend along a longitudinal axis of said overbeam. The fixing profiles 28 are rectilinear. The fixing profiles extend over the entire length of the overbeam.

[0166] Each of the fixing profiles 28 comprises a longitudinal rib 29 along the entire length of said fixing profile. Each of the ribs 29 is located at a distal end of the fixing profile 28 along which it extends. The rib 29 cooperates with the groove 44 of the supporting beam 4, in particular by clipping.

[0167] The overbeam 10 can slide along the supporting beam 4, as illustrated in figures 9 And 10 .

[0168] The 10 overbeam is made of aluminum.

[0169] The auxiliary beams 6 are perpendicular to the supporting beams 4. The auxiliary beam(s) 6 extend parallel to the slats. In this embodiment, the auxiliary beams 6 have all the characteristics of the supporting beams 4.

[0170] As illustrated in figures 1 to 3 And 7 à 8 , the lightweight construction element 1 comprises a plurality of blades 8. The support structure 2 comprises a row of nineteen blades 8. The blades 8 are arranged parallel side by side.

[0171] The blades 8 are fixed at their ends to the two supporting beams 4, transversely to them. The blades 8 are mounted freely rotatable around their longitudinal axis.

[0172] The blades 8 have a generally rectangular shape. The blades 8 define two main faces 34, 36. The main faces 34, 36 are rectangular.

[0173] The blades 8 can define two lateral faces 31 perpendicular to the main faces 34, 36, in particular opposite the supporting beam 4. The lateral faces 31 can be trapezoidal in shape, in particular rectangular.

[0174] The 8 blades are hollow.

[0175] Each of the blades 8 has a first profile 38 in the form of a gutter. The first profile 38 is intended to receive and evacuate precipitation when the blade is in the closed position. The first profile 38 extends along an axis parallel to the axis of the blades. The first profile 38 extends over the entire length of the corresponding blade 8.

[0176] Each of the blades 8 has a second profile 39. The second profile 39 is of a complementary shape to the first profile.

[0177] The blades 8 are configured to be movable between an open position and a closed position. In the closed position as seen in the figure 2 , the blades 8 are horizontal. The blades 8 then form a closed surface. The blades form a crenellated surface. The hollows defined at the surface are formed by the first profiles 38 of the blades. In the open position as seen on the figure 3 , the blades are vertical.

[0178] Each of the blades has at its ends an end piece 32 projecting from the lateral faces 31 of said blade 8. The end piece 32 is intended to be inserted into a fixing orifice 18 of the supporting beam 4. The end piece 32 is formed on a fixing cap 30. Two fixing caps 30 are mounted at the lateral faces 31 of each of the blades. The fixing cap 30 has an end piece 32 projecting in a direction parallel to the axis of the blades 8.

[0179] The 8 blades are completely opaque.

[0180] The support structure 2 also includes a crank 14 for modifying the orientation of the blades 8. For this purpose, a connecting bar 15 is screwed directly to each closing cover 30 on the same side of the row of blades 8. The crank 14 is connected to a movement transmission mechanism 16 connecting the crank to the end piece 32 of one of the blades 8 of the row of blades.

[0181] The movement transmission mechanism 16 is capable of transmitting the moment resulting from the actuation of the crank 14 to at least one blade 8 of the row of blades, all of the blades 8 of the row of blades then being driven in rotation by the connecting bar 15.

[0182] The crank 14 can be engaged between a first start-of-stroke position, the blades 8 then being in the open position, and a second end-of-stroke position, the blades 8 then being in the closed position.

[0183] The crank 14 can be operated in an intermediate stroke position, the blades 8 can then be oriented obliquely, at any angle desired by the user.

[0184] The posts 3 have a generally cylindrical shape, with a square section. The posts are hollow. As seen in the figure 6 , the upper part 56 of each of the posts 3 defines a nesting portion 58 intended to receive a supporting beam 4 and an auxiliary beam 6. Two of the walls of the post are shorter than the others, and define on their upper edge a support surface intended to receive said supporting beam 4 and auxiliary beam 6.

[0185] In particular, the post has two notches 59 at its upper portion. Each of the notches 59 is respectively of a shape complementary to that of the end of the supporting beam and the auxiliary beam.

[0186] Thus, the supporting beam 4 and / or the auxiliary beam 6 rest at least partially on the column 3.

[0187] The upper part 56 of the post 3 has fixing means 52, 54 intended to fix the supporting beam 4. Similar fixing means not illustrated are provided for the auxiliary beam 6. The fixing means comprise fixing holes 52 arranged through one of the walls of the post, and screws 54.

[0188] The base of each post has a 60 cover.

[0189] As illustrated in the figure 11 , the overbeam has five through holes 70 arranged along one of its walls. The through holes 70 are circular in shape. In this example, the through holes 70 are identical to each other.

[0190] The through holes 70 are aligned along a single row parallel to the longitudinal axis of the overbeam 10. The through holes 70 are uniformly spaced.

[0191] The support structure 2 may comprise a functional device.

[0192] As illustrated in the figure 11 , the support structure 2 comprises a misting device 72. The misting device 72 is arranged inside the overbeam 10. The misting device 72 comprises nozzles which can be inserted into the orifices 70.

[0193] Alternatively, a sound system 72 may be disposed within the overbeam. The sound system may include a Bluetooth sound bar.

[0194] Alternatively, a lighting device 72 may be arranged inside the overbeam. This lighting device may comprise LEDs which may be inserted into the holes 70.

[0195] Of course, the invention is not limited to the examples just described. The construction element could comprise several functional devices simultaneously, for example a misting device, a sound device and a lighting device. The construction element can also comprise a plurality of cover plates, arranged side by side, replacing the blades.
