Definitions

  • the present invention relates to constituent elements of a grid.
  • a grid is constituted by a mesh of two mutually orthogonal series of parallel metal bars welded together.
  • some of the bars may have a curved shape and, in addition, ironwork patterns may be welded between adjacent bars.
  • a disadvantage of such grids is that the user can not customize and in addition the manufacturer must manage a stock of grids of all sizes possible.
  • there are at least three parameters to manage namely the length and the width of the grid, as well as the nature of the bars, that is to say their appearance.
  • GB 2 268 956 A teaches a grid having a horizontal bar having a lateral notch on which is laterally slidable a branch of a slider or elastic hairpin clip, pushed down towards the horizontal bar to be trapped axially by the two flanks of the notch.
  • the slider thus fixed in axial position on the horizontal bar, is itself a prisoner inside a vertical bar constituted by two U-shaped angles.
  • the present invention aims to simplify the locking assembly in the mutual position of the bars.
  • the invention firstly relates to a set of gate elements, comprising a first plurality of longitudinal bars each comprising a second plurality of securing sections with respectively a said second plurality of sections of coupling belonging to transverse bars, characterized in that each coupling section has a transverse cut and each securing section comprises a securing segment of shape and length adapted to be received in the cut, segment limited by a shoulder of a lateral relief of axial positioning arranged then to be axially opposite an abutment surface forming part of abutment means belonging to the coupling section considered.
  • the shoulder opposes any lateral force that would be exerted, voluntarily or otherwise, on the associated crossbar, and would be likely to deviate from a neighbor.
  • This set of elements is therefore, in storage, in the form of free elements, which are then assembled into a grid.
  • the longitudinal bars extend substantially horizontally and the transverse bars substantially vertically.
  • the abutment coupling As the abutment coupling, supplemented as necessary by the sealing of the ends of the appropriate bars, avoids the need for a mutual welding of the crossed bars, which would be impractical for a common user, it is unnecessary to store all possible types of grid because it can be assembled quickly, by mounting in the desired relative positions, without the risk of not having the desired locking elements, since they are integrated bars.
  • the user can therefore choose the transverse bars independently of the longitudinal bars, either for their length or their shape.
  • the first plurality and / or the second plurality of bars may each be limited to a single bar.
  • the grid may for example be used to protect an opening or be a kind of ladder serving for example support for shelves.
  • the coupling section is of the female type, the cutout being a transverse coupling hole having a clearance jig adapted to be able to ensure the free passage of a longitudinal bar when it forms an axis. having an axis direction aligned with a passage template direction defined by the hole, each securing section being of male type and the shoulder being arranged for, by misalignment between the axis and clearance gauge directions, to come axially facing the abutment surface.
  • the so-called horizontal bars are therefore pins for the vertical bars that are threaded over them by sliding, as long as the orientations of the associated sections are suitable, then the vertical bars are then locked in position by misalignment when they have reached the respective axial positions. provided on the horizontal bars.
  • the respectively coupling and securing sections are arranged so that the misalignment is obtained by axial rotation of at least one of the longitudinal bar and the crossbar considered or by a relative pivoting between the longitudinal bar and the crossbar. associated.
  • the user rotates each vertical bar around its axis then seals at least two at least one end, without having to seal the horizontal bars, trapped vertical bars, or it rotates each horizontal bar about its axis to angularly position said lateral relief axially opposite the abutment surface of the female section, coupling.
  • pivoting the user assembles the bars according to a mesh forming meshes having the initial angle allowing the desired mounting between the bars, for example lozenges, then it deforms the lattice in its plane so that the meshes take the form intended to perform the desired locking, for example rectangles. In such a case, a minimum of sealing points is sufficient to maintain the coupling.
  • the shoulder is turned away from another shoulder, arranged to cooperate with another abutment surface forming part of the control means. stop.
  • the coupling hole has a non-circular passage template, having a recess to which is substantially adjusted a protuberance of the transverse profile of the longitudinal bar, except that the securing segment has a recessed profile, limiting the bottom of a notch whose first edge constitutes the said shoulder, the recessed profile existing over a defined axial length of notch and being shaped to allow axial rotation of the male section so that the shoulder exits the passage template.
  • the notch preferably has a second edge, constituting the second shoulder, spaced from the first edge of at least one said notch length corresponding to a length of the coupling hole, to form a pair of jaws able to trap axially.
  • two opposite mouths of the coupling hole respectively the first and second edges.
  • the securing notch may be separated axially into two sub-segments by a portion of a section comprising said protuberance, constituting an index intended to be received in a cavity formed in a wall of the coupling hole.
  • the index thus provides bidirectional axial locking.
  • the securing respectively coupling and securing sections may thus for example have respectively threaded and threaded peripheries, on at least one angular sector, of rack, respectively corresponding to the lateral relief and the abutment means.
  • the bidirectional lock is thus distributed.
  • the securing section may have an elongated cross-section of reduced size but having a length greater than said width of flattening of the jig of passage.
  • the passage template is elongate, that is to say substantially elliptical or lenticular, with an extension direction substantially along the axial direction of the bar cross section considered, allows to limit the necessary thickness of the transverse bars, that is to say, to maintain a certain wall thickness at the transverse cut, which is for example a said coupling hole.
  • the respective coupling holes of two transverse bars have between them a mirror symmetry, so that said axial rotation of the securing section, causing the exit of the shoulder out of the clearance template, represents a relative tilting in one direction, one of the two transverse bars around the longitudinal bar, and represents a relative tilting, in the opposite direction, of the other of the two transverse bars.
  • the respective holes, at a given height, transverse bars having been aligned it is first necessary to tilt the successive transverse bars respectively on one side and the other of the planned plane of the grid, that is to say that it has a lateral profile in V. Then, by pivoting according to a given angular sector in a plane perpendicular to the planned common plane, each transverse bar is folded in the plane expected, thus transforming the "V" profile into an "I".
  • the clearance template can be provided to be progressively flattened by misalignment of the clearance gauge direction with respect to the axis direction, following said relative pivoting or said rotation of the cross bar, until that the jig passage no longer fully encompasses the shoulder.
  • At least one pair of associated bars longitudinal and transverse, is hermaphroditic, with respectively a said female coupling section and a said male securing section. The mutual locking of the bars is thus better ensured.
  • the set of bars may in particular comprise two said pairs of hermaphrodite bars provided to form a parallelogram having a pair of couplings of a first type, inverse of the first type, that is to say dual, along a diagonal and a pair of couplings of a second type according to another diagonal.
  • the interlocking mesh of the bars is thus optimal.
  • the male section of a first longitudinal bar of this kind can be followed by another male section and the female section of a second longitudinal bar of this kind can be followed by another female section. This offers several possibilities for various assemblies of other bars.
  • a transverse bar i.e., with coupling holes, may be provided to be mounted in longitudinal position by coupling the coupling hole with a transverse bar.
  • Such a bar is therefore versatile because it can be effectively transverse, and thus offer a coupling and stop hole, but it can also serve as a pin for another crossbar, that is to say have the function of a longitudinal bar.
  • This multipurpose bar will therefore have a reduced section to be able to cross the hole of the associated crossbar, or the crossbar actually will have a hole with extended section in the extension direction of this crossbar, and the multipurpose bar will present a section lengthened in the same way.
  • the longitudinal bars and the transverse bars have said cutouts distributed on two opposite sides of the bars.
  • Some of the longitudinal bars and crossbars preferably comprise end sections arranged to be sealed.
  • transverse bars may have a folded conformation in a decorative pattern of determined size, with two opposite and aligned coupling holes, to be threaded on a single longitudinal bar, inserted between two elongated transverse bars each threaded on the plurality of bars cross.
  • the user can thus successively thread patterns of different shapes, for example in a circle, diamond, heart, S or other, on each of the longitudinal bars, and thus customize its grid.
  • these patterns constitute spacers between the elongate transverse bars and contribute to locking in translation of the other transverse bars on the longitudinal bars.
  • this shape characteristic of a transverse bar is independent of the means, integrated or not, locking in position of the bars.
  • the invention also relates to a transverse bar for forming a set of grid elements according to the invention, characterized in that it comprises a said first plurality of coupling sections each having a transverse cut, for receiving a longitudinal bar, associated with abutment means comprising an abutment surface provided to cooperate with a shoulder of the bar longitudinal.
  • the coupling section is preferably of the female type, the cutout being a transverse coupling hole having a passage template adapted to be able to ensure the free passage of a longitudinal bar when it forms an axis having a direction of axis aligned on a passage template direction defined by the coupling hole, said cooperation of the abutment surface being obtained by misalignment between the axis directions and clearance template.
  • the invention finally relates to a longitudinal bar for forming a set of grid elements according to the invention, characterized in that it comprises a said second plurality of securing sections with respectively a said second plurality of coupling sections belonging to transverse bars having receiving cutouts, each joining section comprising a securing segment, of shape and length adapted to be received in a said cut, segment limited by a shoulder of a lateral relief of axial positioning arranged for then find axially facing an abutment surface forming part of abutment means belonging to the coupling section considered.
  • each securing section is then male type and the shoulder is arranged for, by misalignment between the axis directions and clearance gauge, come axially facing the abutment surface.
  • the Figures 1 to 4 represent details of coupling elements exposing the first embodiment of bars constituting a grid 1, serving as protection in this example, whose general shape is represented on the Figures 5 and 6 , which further expose the second embodiment.
  • the grid 1 comprises a first plurality of here two bars 2 and 3, said longitudinal, here identical and horizontal in this example and further serving here to the anchoring of the grid 1, and a second plurality of here two bars 4, 5, transversely extending, here orthogonal in final position ( Fig. 6 ), relative to the longitudinal bars 2 and 3.
  • the transverse bars 4, 5 are here identical and are used for masking an opening, not shown, whose excessive height prohibits the use of only the two longitudinal bars 2 and 3, or whose excessive width would require longitudinal bars 2, 3 too long and therefore easy to separate mutually.
  • the bars or bars 2 to 5 are rectilinear. It can be expected that the end sections of the longitudinal bars 2, 3 have a forked shape or other de sealing, not drawn, to better ensure anchoring.
  • the anchor requires that one of the two sets of bars 2, 3 and 4, 5 is longer than the corresponding dimension of the protected opening and the other series of bars is shorter that the other dimension of the opening if the grid 1 extends opposite the edge of the opening, we could consider that it is the transverse bars that are anchored, especially in a case for which they would be few for example as here there are two.

Fig. 2 ), that is to say that it has an elongate shape, substantially in ellipse, in approximately the extension direction defined by the axis 40, this elongated shape being here extension axis slightly inclined in this direction .
  • the second passage template of geometric axis 42A2 is narrower, that is to say corresponds to the cross section of the securing segment 22, that is to say the first elementary passage template but decreased by notches 24 and 25.

  12. Anordnung nach einem der Ansprüche 2 bis 11, wobei mindestens ein Paar (2, 4) von einander zugeordneten Stäben, einem Längs- und einem Querstab, ein Paar von Zwittern ist, mit jeweils einem besagten weiblichen Kopplungsabschnitt (41) und einem besagten männlichen Verbindungsabschnitt (21).
  13. Anordnung nach Anspruch 12, welche zwei besagte Paare (2, 4 und 3, 5) von Zwitter-Stäben aufweist, die dafür vorgesehen sind, ein Parallelogramm zu bilden, das auf einer Diagonalen ein Paar von Kopplungen eines ersten Typs und auf einer anderen Diagonalen ein Paar von Kopplungen eines zweiten Typs, der zu dem ersten Typ invers ist, aufweist.
  14. Anordnung nach Anspruch 13, wobei auf den männlichen Abschnitt (21) eines ersten Längsstabes (2) ein weiterer männlicher Abschnitt (21) folgt und auf den weiblichen Abschnitt (41) eines zweiten Längsstabes (3) ein weiterer weiblicher Abschnitt (41) folgt.
  15. Anordnung nach einem der Ansprüche 1 bis 14, wobei die Längsstäbe (2, 3) und die Querstäbe (4, 5) besagte Ausschnitte (42, 142) aufweisen, die auf zwei gegenüberliegenden Seiten der Stäbe (2, 3, 4, 5) verteilt sind.
  16. Anordnung nach einem der Ansprüche 2 bis 15, wobei ein besagter Querstab (5) dafür vorgesehen ist, durch Kopplung des Kopplungsloches (41) mit einem Querstab (4) in einer Längsposition angebracht zu werden.
  17. Anordnung nach einem der Ansprüche 1 bis 16, wobei einige von den Längsstäben (2, 3) und den Querstäben (4, 5) Endabschnitte umfassen, die dafür ausgebildet sind, vergossen zu werden.
  18. Anordnung nach einem der Ansprüche 2 bis 17, wobei das Durchgangsprofil eine Form aufweist, die im Wesentlichen entlang einer Erstreckungsrichtung des betreffenden Querstabes (4, 5) langgestreckt ist.
  19. Anordnung nach einem der Ansprüche 1 bis 18, wobei einige der Querstäbe (4, 5) eine gemäß einem dekorativen Motiv mit einem bestimmten Platzbedarf gebogene Gestalt aufweisen, mit zwei gegenüberliegenden und fluchtenden Kopplungslöchern, um auf einen einzigen Längsstab (2, 3) aufgesteckt zu werden, eingefügt zwischen zwei langgestreckten Querstäben (4, 5), die jeweils auf die Vielzahl von Längsstäben (2, 3) aufgesteckt sind.
  20. Querstab (2, 3) zum Ausbilden einer Anordnung von Gitterelementen (1) nach einem der Ansprüche 1 bis 18, dadurch gekennzeichnet, dass er eine besagte erste Vielzahl von Kopplungsabschnitten (41) aufweist, die jeweils einen quer hindurch verlaufenden Ausschnitt (42, 43) zur Aufnahme eines Längsstabes (2, 3) aufweisen, der mit Anschlagmitteln verbunden ist, die eine Anschlagfläche (248B, 249B) umfassen, die dazu vorgesehen ist, mit einer Schulter des Längsstabes (2, 3) zusammenzuwirken.
  21. Querstab nach Anspruch 20, wobei der Kopplungsabschnitt (41) vom "weiblichen Typ" ist, wobei der Ausschnitt ein quer verlaufendes Kopplungsloch (42, 43) ist, das ein Durchgangsprofil aufweist, das dafür eingerichtet ist, den freien Durchgang eines Längsstabes (2, 3) sicherzustellen, wenn er eine Achse mit einer Achsenrichtung (20) bildet, die mit einer durch das Kopplungsloch (42, 142A) definierten Durchgangsprofillrichtung (42A, 142A) fluchtet, wobei das Zusammenwirken der Anschlagfläche (248B, 249B) durch Fluchtabweichung zwischen der Achsenrichtung (20) und der Durchgangsprofilrichtung (42A, 142A) erzielt wird.
  22. Längsstab (2, 3) zum Ausbilden einer Anordnung von Gitterelementen (1) nach einem der Ansprüche 1 bis 19, dadurch gekennzeichnet, dass er eine besagte zweite Vielzahl von Abschnitten (21) zur Verbindung mit je einer besagten zweiten Vielzahl von Kopplungsabschnitten (41) aufweist, die zu Querstäben (4, 5) gehören, welche Aufnahmeausschnitte (42, 142) aufweisen, wobei jeder Verbindungsabschnitt (21) ein Verbindungssegment (22) umfasst, dessen Form und Länge dafür eingerichtet sind, in einem besagten Ausschnitt (42, 142) aufgenommen zu werden, wobei das Segment (22) von einer Schulter (242, 243) eines seitlichen Reliefs zur axialen Positionierung begrenzt wird, die dafür ausgebildet ist, sich dann axial gegenüber einer Anschlagfläche (248B, 249B) zu befinden, die Teil von Anschlagmitteln ist, die zu dem betreffenden Kopplungsabschnitt (41) gehören.
