Description

  • [0001]
    La présente invention a pour objet un élément de parquet démontable. The present invention relates to a removable parquet element.
  • [0002]
    Dans de nombreuses applications, il est fait appel à des parquets démontables destinés à être placés provisoirement sur un sol, par exemple en vue de manifestations sportives ou culturelles temporaires, dans des salles de sports ou de spectacles. In many applications, it uses removable flooring to be placed temporarily on the ground, for example for temporary sports or cultural events, in sports halls and shows.
  • [0003]
    De nombreux types de parquets démontables ont déjà été proposés. Many types of removable floors have already been proposed. Parmi ceux-ci, on connait un parquet formé d'un assemblage de plaques rectangulaires d'environ 1,80m de longueur et 50cm de largeur. Of these, we know a flooring formed by an assembly of rectangular plates of approximately 1.80 m in length and 50cm in width. Sur l'une des grandes rives de ces plaques débouche un organe de liaison en forme de plaquette métallique dont les bords sont relevés à 90°. On one of the large sides of these plates there opens a shaped connecting element of metal plate whose edges are raised to 90 °. La face inférieure des plaques comporte des rainures longitudinales et transversales qui s'étendent jusqu'à ses rives. The lower face of the plates has longitudinal and transverse grooves which extend up to its banks. L'assemblage des éléments de parquet entre eux s'opère par recouvrement des plaquettes, les bords relevés de celles-ci étant logés dans les rainures de la plaque de parquet adjacente. The assembly of parquet parts together is achieved by recovery of platelets, the raised edges thereof being accommodated in the grooves of the adjacent flooring plate.
  • [0004]
    Les éléments de parquet sont destinés à être disposés en quinconce les uns par rapport aux autres, si bien qu'il est prévu des plaques de plus petites dimensions pour les bordures du parquet. Parquet elements are intended to be arranged in staggered relation to each other, so there are provided plates of smaller dimensions to the edges of the parquet.
  • [0005]
    Du fait que les rainures que présentent la face inférieure des plaques sont débouchantes, il est nécessaire de prévoir des plaques de bordure spéciales avec des rainures non apparentes, c'est-à-dire non débouchantes. Because the grooves that have the underside of the plates are opening out, it is necessary to provide special edging plates with no visible grooves, that is to say, not emerging. On peut également prévoir des éléments de bordure additionnels dont la fonction est de masquer les rives des plaques de parquet. There may also be additional border elements whose function is to mask the banks of the parquet plates.
  • [0006]
    L'objectif de l'invention est de proposer un nouveau type d'élément de parquet démontable qui, tout en étant d'une conception simple et d'un prix de revient modéré, ne présente pas l'inconvénient des éléments de parquet décrits plus haut. The objective of the invention to provide a new type of removable flooring element which, while being of simple design and moderate cost, does not have the drawback of parquet elements described above.
  • [0007]
    Ce résultat est atteint, conformément à l'invention, grâce au fait que l'élément de parquet démontable, qui consiste en une plaque rectangulaire, comporte au moins deux pattes de liaison en forme de "T" dont la branche longitudinale s'étend perpendiculairement à l'une des rives de la plaque et dont la branche transversale s'étend parallèlement à ladite rive, tandis qu'il est prévu sous la plaque, débouchant sur la rive opposée et en regard desdites pattes, des évidements de contour en forme de "T", de forme sensiblement complémentaire de celle des pattes, ce qui - par emboîtement des pattes dans les évidements - permet l'assemblage, rive contre rive, de deux éléments de parquet adjacents. This result is achieved, according to the invention, thanks to the fact that the removable parquet element which consists of a rectangular plate, comprises at least two L-shaped connecting tabs "T" which the longitudinal leg extends perpendicularly to one of the sides of the plate and whose transverse leg extends parallel to said edge, while it is provided in the plate, leading to the opposite side and facing said legs, contour-shaped recesses of "T", of substantially complementary shape to that of the lugs, which - by interlocking the tabs in the recesses - allows the assembly, against shore bank, two adjacent parquet elements.
  • [0008]
    Selon d'autres caractéristiques avantageuses, mais non limitatives : According to other advantageous characteristics, but not limiting:
    • les évidements ont des bords d'entrée évasés, ce qui facilite la mise en place des pattes en "T" lors de l'emboîtement ; the recesses have tapered entry edges, which facilitates the establishment of the tabs "T" during engagement;
    • les branches du "T" sont des tiges cylindriques, la tige transversale, de plus petit diamètre, traversant la tige longitudinale ; the branches of the "T" are cylindrical rods, the transverse rod of smaller diameter, passing through the longitudinal rod;
    • la tige longitudinale possède une portion d'extrémité (côté opposé à la tige transversale) qui est filetée, ce qui permet de la fixer par vissage à la plaque ; the longitudinal rod has an end portion (opposite side to the cross rod) which is threaded, which allows to fix by screwing the plate;
    • la rive de la plaque équipée desdites pattes est pourvue d'une nervure qui fait corps avec la plaque, tandis que la rive opposée présente une rainure de forme complémentaire ; the side of the plate equipped with said lugs is provided with a rib which is integral with the plate, while the opposite side has a complementary-shaped groove;
    • lorsque l'élément comporte deux pattes de fixation, celles-ci sont disposées à un quart et aux trois quarts de la longueur de la rive. when the element comprises two attachment tabs, the latter are arranged at one quarter and three quarters of the length of the bank.
      D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre, faite en référence aux dessins annexés dans lesquels : Other features and advantages of the invention will appear on reading the detailed description that follows, with reference to the accompanying drawings in which:

    • la figure 8 est une vue de dessus schématique de plusieurs plaques de parquet en cours d'assemblage les unes aux autres. Figure 8 is a schematic top view of several floors being assembled plates to each other.
  • [0009]
    L'élément de parquet 1 représenté à la figure 1 est formé d'une plaque rectangulaire composée d'un ensemble de lattes de parquet traditionnelles juxtaposées 10, par exemple en hêtre. The flooring 1 illustrated in Figure 1 element is formed of a rectangular plate composed of a set of juxtaposed traditional floorboards 10, for example beech.
  • [0010]
    A titre indicatif, la plaque 1 peut avoir une dimension de lm par 0,50m, et une épaisseur d'environ 20mm. As an indication, the plate 1 may have a dimension of film by 0.50m and a thickness of about 20mm. L'une des grandes rives 14 de la plaque est pourvue d'une nervure longitudinale 12 qui fait corps avec elle. One of the major sides 14 of the plate is provided with a longitudinal rib 12 which is integral with it. La rive opposée 15 est pourvue d'une rainure complémentaire 13, visible à la figure 3. Les deux autres rives de la plaque comportent une rainure 11 identique à la rainure 13. The opposite side 15 is provided with a complementary groove 13, visible in Figure 3. The other two sides of the plate comprise a groove 11 identical to groove 13.
  • [0011]
    Selon une caractéristique importante de l'invention, la plaque 1 comporte deux pattes de liaison 2 qui s'étendent perpendiculairement à la rive 14. According to an important feature of the invention, the plate 1 has two connecting lugs 2 which extend perpendicular to the edge 14.
  • [0012]
    Chaque patte a la forme générale d'un "T". Each tab has the general shape of a "T".
  • [0013]
    Elle est composée de deux tiges métalliques cylindriques 20, 21, qui forment respectivement la branche longitudinale et la branche transversale du "T". It consisted of two cylindrical metal rods 20, 21 which respectively form the longitudinal branch and the transverse branch of the "T".
  • [0014]
    A titre indicatif, la tige 20 a une longueur de l'ordre de 70 mm et un diamètre de l'ordre de 8 mm. As an indication, the rod 20 has a length of about 70 mm and a diameter of about 8 mm. La tige 21 a une longueur de l'ordre de 40 mm et un diamètre de l'ordre de 3 mm. The rod 21 has a length of about 40 mm and a diameter of about 3 mm. La tige 21 est emmanchée à force dans un trou percé diamétralement dans la zone d'extrémité de la tige 20. Elle est disposée parallèlement au plan de la plaque 1. The rod 21 is press fit into a hole drilled diametrically in the end region of the rod 20. It is arranged parallel to the plane of the plate 1.
  • [0015]
    Comme le montre la figure 4, la tige 20 se prolonge, du côté opposé à la branche 21, par une portion filetée, par laquelle elle est vissée dans un trou formé dans la plaque 1. Son filetage est avantageusement du type autotaraudeur, ce qui permet de la visser dans un trou lisse. As shown in Figure 4, the rod 20 extends, on the side opposite the branch 21, by a threaded portion by which it is screwed into a hole formed in the plate 1. The thread is advantageously of the self-tapping type, which allows screwing it into a smooth hole.
  • [0016]
    De préférence la tige 20 est centrée dans l'épaisseur de la plaque. Preferably the rod 20 is centered in the thickness of the plate.
  • [0017]
    Sur la rive 15 de la plaque débouchent des évidements 3 disposés en regard des pattes 2. On the bank 15 of the plate open recesses 3 arranged facing the two legs.
  • [0018]
    Chaque évidement 3 est destiné à recevoir, par emboîtement, et à retenir la patte 2 située en vis-à-vis et portée par une plaque 1 adjacente au cours de l'installation du parquet. Each recess 3 is designed to receive, by fitting, and retaining tab 2 located vis-à-vis and carried by a plate 1 adjacent in the installation of flooring.
  • [0019]
    L'évidement 3, bien visible à la figure 3, est une cavité creusée par fraisage dans le dessous de la plaque 1. Il a un contour en "T" conformé à la patte 2, et une profondeur suffisante pour permettre l'emboîtement de cette patte, et pour la retenir sans jeu, ou pratiquement sans jeu. The recess 3, although visible in Figure 3, a cavity is milled in the underside of the plate 1. It has a contour "T" shaped with the leg 2, and a depth sufficient to allow nesting of this lug, and to retain it without play or virtually without play.
  • [0020]
    On a désigné par la référence 30 la partie longitudinale de l'évidement, qui reçoit la branche 20, et par la référence 31 sa partie transversale, qui reçoit la branche 21. Elles ont toutes deux des bords d'entrée évasés (tulipés) 300, respectivement 310, qui facilitent l'opération d'emboîtement en assurant un centrage et un guidage des tiges. Was designated by the reference 30 the longitudinal section of the recess, which receives the arm 20 and by reference 31 its transverse portion, which receives the leg 21. Both have flared inlet edges (tulip-shaped) 300 , respectively 310, which facilitate the fitting operation by providing a centering and guiding the rods.
  • [0021]
    Dans la forme de réalisation de la figure 1, les pattes 2 et les évidements 3 sont disposés à environ un quart et trois quarts de la longueur des rives 14 et 15. In the embodiment of Figure 1, the legs 2 and 3 the recesses are arranged at about a quarter and three quarters of the length of sides 14 and 15.
  • [0022]
    En référence aux figures 4 à 8, nous allons maintenant expliquer de quelle manière se fait l'assemblage d'un élément de parquet avec d'autres éléments déjà posés. With reference to Figures 4 to 8, we will now explain in what way is assembling a parquet element with other elements already laid.
  • [0023]
    Comme on le voit à la figure 8, les différents éléments se placent en quinconce. As seen in Figure 8, the various elements are placed in staggered rows. L'élément 1d à mettre en place est destiné à se positionner, par l'un de ses grands côtés, à cheval contre deux éléments voisins 1a et 1b d'une rangée d'éléments déjà posées, et par l'un de ses petits côtés contre un élément 1c de la rangée en cours. The element 1d to implement is intended to be positioned, by one of its long sides, a horse against two adjacent elements 1a and 1b of a row of already laid elements, and by one of its small sides against a member 1c of the current row.
  • [0024]
    Le transport et la manipulation des plaques, en vue de leur mise en place, se font de manière aisée car la forme en "T" des pattes 20 permet à l'opérateur de les saisir facilement. The transport and handling of plates, for their implementation, will make a simple manner because the shape "T" legs 20 allows the operator to grasp them easily. Ils jouent en quelque sorte le rôle (annexe) de poignées. They play somehow the role (Annex) handles.
  • [0025]
    A la partie gauche des figures 4 et 5, on a représenté le bord de l'élément 1a déjà posé sur le sol 100, ce sol étant par exemple une surface en béton. At the left side of Figures 4 and 5, there is shown the edge of the element 1a already placed on the floor 100, the soil being for example a concrete surface. Sur la partie droite de ces figures, on a représenté le bord correspondant de l'élément 1d à mettre en place. On the right side of these figures, the corresponding edge shows the element 1d to implement.
  • [0026]
    L'opérateur saisit l'élément 1d et le rapproche des éléments 1a et 1b déjà posés tout en faisant glisser sa rive 16 contre la rive correspondante 17 de l'élément 1c. The operator grasps the element 1d and approaches the elements 1a and 1b already laid while sliding its edge 16 against the corresponding side 17 of the element 1c. II effectue cette opération en manipulant la plaque alors que celle-ci est inclinée par rapport à l'horizontale, comme le montre la figure 4. It does this by manipulating the plate so that it is inclined relative to the horizontal, as shown in Figure 4.
  • [0027]
    L'élément 1d étant latéralement en appui contre l'élément 1c déjà posé, les évidements 3 se trouvent en face des pattes 2 des éléments 1a et 1b, au cours de cette opération. The element 1d laterally bearing against the already laid element 1c, the recesses 3 are opposite the lugs 2 of the elements 1a and 1b, during this operation.
  • [0028]
    L'élément 1d est rapproché des éléments 1a, 1b, comme symbolisé par la flèche f . The element 1d has approached the elements 1a, 1b, as symbolized by the arrow f.
  • [0029]
    Lorsque l'élément 1d arrive en contact avec l'élément 1a, la rainure 13 de l'élément 1d s'engage contre la nervure 12 de l'élément 1a. When the element 1d comes into contact with the element 1a, the groove 13 of 1d element engages against the rib 12 of the element 1a. Il suffit alors de poser l'élément 1d au sol, dans le sens de la flèche g . Then simply place the component 1d on the ground, in the direction of the arrow g. En effectuant cette opération, I'évidement 3 vient prendre place automatiquement sur la patte 2 de l'élément 1d puisque ceux-ci sont disposés en regard les uns des autres. By performing this operation, I'évidement 3 takes its place automatically on the leg 2 of the element 1d since they are disposed facing each other. Le tulipage 300, 310 prévu à l'entrée des parois des cavités 30 et 31 facilite cet emboîtement, réalisant un autocentrage des pattes dans leur logement. The belling 300, 310 provided at the inlet of the cavity walls 30 and 31 facilitates this fitting, providing a self-centering of the legs in their housing.
  • [0030]
    Une fois la mise en place effectuée, les éléments 1a et 1d occupent les positions illustrées aux figures 5 à 7. Once the implementation carried out, the elements 1a and 1d occupy the positions illustrated in Figures 5 to 7.
  • [0031]
    Il faut noter que lorsque deux éléments d'une même rangée ont été posés, par exemple les éléments 1c et 1d, on introduit une fausse languette connue en soi dont l'espace généré par les rainures que présentent les petites rives 16 et 17 des éléments de parquet. Note that when two elements of the same row has been laid, e.g. elements 1c and 1d, is introduced spline known per se including the space generated by the grooves that have small banks 16 and 17 of the elements wooden floors. La fonction - bien connue - de cette fausse languette est de maintenir exactement bord à bord les éléments voisins de telle sorte qu'il n'y ait pas de solution de continuité dans la surface du parquet et que les sollicitations pondérales s'exerçant sur un élément sont transmises aux éléments voisins. The function - well known - this spline is to maintain exactly alongside neighboring elements so that there is no continuity in the surface of the floor and make the weight loads acting on a element are transmitted to the neighboring elements.
  • [0032]
    Bien entendu, l'opération décrite plus haut est réitérée pour couvrir la totalité du sol à équiper. Of course, the above operation is repeated to cover the entire floor to be equipped.
  • [0033]
    Les éléments de parquet étant disposés en quinconce, il est nécessaire de prévoir des éléments de petite taille dans les bouts de rangée. Parquet elements being arranged in staggered rows, it is necessary to provide small elements in the ends of row. Ces éléments possèdent une seule patte et un seul évidement correspondant, du fait que leur longueur est la moitié de celle des éléments qui viennent d'être décrits. These elements have one leg and one corresponding recess, that their length is half that of the elements that have just been described.
  • [0034]
    Il va de soi que le choix de dimensions et des matériaux de l'élément de parquet selon l'invention sera fait en fonction des différentes contraintes auquel sera soumis le parquet. It goes without saying that the choice of dimensions and materials of the parquet element of the invention will be made based on various constraints which will be subject the floor.
  • [0035]
    Une fois le parquet complètement posé, les éléments de liaison sont parfaitement invisibles. Once completely installed floors, the connecting elements are perfectly invisible. La cohésion des éléments de parquets entre eux est parfaite, aussi bien horizontalement que verticalement. The cohesion of the flooring elements between them is perfect, both horizontally and vertically.
