- the element 1d being laterally in abutment against the element 1c already placed, the recesses 3 are located opposite the tabs 2 of the elements 1a and 1b, during this operation.
- the element 1d is compared with the elements 1a, 1b, as symbolized by the arrow f .
- the groove 13 of the element 1d engages against the rib 12 of the element 1a. It then suffices to place the element 1d on the ground, in the direction of the arrow g . By carrying out this operation, the recess 3 comes to take place automatically on the tab 2 of the element 1d since these are arranged opposite one another.
- the tulping 300, 310 provided at the entrance to the walls of the cavities 30 and 31 facilitates this nesting, achieving self-centering of the legs in their housing.
- parquet elements being staggered, it is necessary to provide small elements in the row ends. These elements have a single tab and a single corresponding recess, because their length is half that of the elements which have just been described.
Abstract
Description
La présente invention a pour objet un élément de parquet démontable.The present invention relates to a removable parquet element.
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, removable floors are used which are intended to be temporarily placed on a floor, for example for temporary sporting or cultural events, in sports halls or shows.
De nombreux types de parquets démontables ont déjà été proposés. Parmi ceux-ci, on connait un parquet formé d'un assemblage de plaques rectangulaires d'environ 1,80m de longueur et 50cm de largeur. 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°. La face inférieure des plaques comporte des rainures longitudinales et transversales qui s'étendent jusqu'à ses rives. 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.Many types of removable parquet have already been proposed. Among these, we know a parquet formed by an assembly of rectangular plates of about 1.80m in length and 50cm in width. On one of the large banks of these plates opens a connecting member in the form of a metal plate, the edges of which are raised at 90 °. The underside of the plates has longitudinal and transverse grooves which extend to its edges. The parquet elements are joined together by covering the plates, the raised edges of these being housed in the grooves of the adjacent parquet plate.
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.The parquet elements are intended to be staggered with respect to each other, so that smaller plates are provided for the edges of the parquet.
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. On peut également prévoir des éléments de bordure additionnels dont la fonction est de masquer les rives des plaques de parquet.Because the grooves on the underside of the plates are through, it is necessary to provide special edge plates with non-visible grooves, that is to say not through. One can also provide additional border elements whose function is to hide the edges of the parquet sheets.
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 is to propose a new type of removable parquet element which, while being of a simple design and a moderate cost price, does not have the disadvantage of the parquet elements described more high.
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 connecting tabs in the shape of a "T" the longitudinal branch of which extends perpendicularly to one of the edges of the plate and the transverse branch of which extends parallel to said bank, while it is provided under the plate, opening onto the opposite bank and facing said legs , contour recesses in the shape of a "T", of shape substantially complementary to that of the legs, which - by nesting the legs in the recesses - allows the assembly, edge against edge, of two adjacent parquet elements.
Selon d'autres caractéristiques avantageuses, mais non limitatives :
- les évidements ont des bords d'entrée évasés, ce qui facilite la mise en place des pattes en "T" lors de l'emboîtement ;
- les branches du "T" sont des tiges cylindriques, la tige transversale, de plus petit diamètre, traversant la tige longitudinale ;
- 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 ;
- 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 ;
- 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.
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 : - la figure 1 est une vue générale, en perspective, d'un élément de parquet ;
- la figure 2 est une vue de détail, en perspective, d'une partie (arrachée) de l'élément de parquet pourvue d'une patte de fixation ;
- la figure 3 est une vue de détail, toujours en perspective mais de dessous, d'une partie (arrachée) de l'élément de parquet pourvue d'un évidement ;
- les figures 4 et 5 sont des vues en coupe suivant l'axe longitudinal d'une patte, illustrant l'opération d'assemblage de deux éléments adjacents ;
- les figures 6 et 7 sont des sections transversales selon les plans VI-VI et, respectivement, VII-VII de la figure 5 ;
- la figure 8 est une vue de dessus schématique de plusieurs plaques de parquet en cours d'assemblage les unes aux autres.
- the recesses have flared entry edges, which facilitates the positioning of the "T" tabs during nesting;
- the branches of the "T" are cylindrical rods, the transverse rod, of smaller diameter, crossing the longitudinal rod;
- the longitudinal rod has an end portion (side opposite to the transverse rod) which is threaded, which makes it possible to fix it by screwing to the plate;
- the edge of the plate equipped with said tabs is provided with a rib which is integral with the plate, while the opposite edge has a groove of complementary shape;
- when the element has two fixing lugs, these are arranged at a quarter and three quarters of the length of the edge.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows, made with reference to the appended drawings in which: - Figure 1 is a general perspective view of a parquet element;
- Figure 2 is a detail view, in perspective, of a part (cut away) of the parquet element provided with a fixing lug;

- Figures 6 and 7 are cross sections along planes VI-VI and, respectively, VII-VII of Figure 5;
- Figure 8 is a schematic top view of several parquet plates being assembled to each other.
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
A titre indicatif, la plaque 1 peut avoir une dimension de lm par 0,50m, et une épaisseur d'environ 20mm. L'une des grandes rives 14 de la plaque est pourvue d'une nervure longitudinale 12 qui fait corps avec elle. 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.As an indication, the
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 characteristic of the invention, the
Chaque patte a la forme générale d'un "T".Each leg has the general shape of a "T".
Elle est composée de deux tiges métalliques cylindriques 20, 21, qui forment respectivement la branche longitudinale et la branche transversale du "T".It is composed of two
A titre indicatif, la tige 20 a une longueur de l'ordre de 70 mm et un diamètre de l'ordre de 8 mm. La tige 21 a une longueur de l'ordre de 40 mm et un diamètre de l'ordre de 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.As an indication, the
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 FIG. 4, the
De préférence la tige 20 est centrée dans l'épaisseur de la plaque.Preferably the
Sur la rive 15 de la plaque débouchent des évidements 3 disposés en regard des pattes 2.On the
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
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
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.We have designated by the
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 FIG. 1, the
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 FIGS. 4 to 8, we will now explain how an element of parquet is assembled with other elements already laid.
Comme on le voit à la figure 8, les différents éléments se placent en quinconce. 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.As seen in Figure 8, the different elements are staggered. The
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. Ils jouent en quelque sorte le rôle (annexe) de poignées.The transport and handling of the plates, with a view to their positioning, is done in an easy manner because the "T" shape of the
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. Sur la partie droite de ces figures, on a représenté le bord correspondant de l'élément 1d à mettre en place.In the left part of Figures 4 and 5, there is shown the edge of the
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. 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.The operator grasps
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
L'élément 1d est rapproché des éléments 1a, 1b, comme symbolisé par la flèche f.The
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. Il suffit alors de poser l'élément 1d au sol, dans le sens de la flèche 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. 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.When the
Une fois la mise en place effectuée, les éléments 1a et 1d occupent les positions illustrées aux figures 5 à 7.Once the installation has been carried out, the
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. 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.It should be noted that when two elements of the same row have been placed, for example the
Bien entendu, l'opération décrite plus haut est réitérée pour couvrir la totalité du sol à équiper.Of course, the operation described above is repeated to cover the entire floor to be equipped.
Les éléments de parquet étant disposés en quinconce, il est nécessaire de prévoir des éléments de petite taille dans les bouts de rangée. 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.The parquet elements being staggered, it is necessary to provide small elements in the row ends. These elements have a single tab and a single corresponding recess, because their length is half that of the elements which have just been described.
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 according to the invention will be made according to the different constraints to which the parquet will be subjected.
Une fois le parquet complètement posé, les éléments de liaison sont parfaitement invisibles. La cohésion des éléments de parquets entre eux est parfaite, aussi bien horizontalement que verticalement.Once the parquet is completely laid, the connecting elements are perfectly invisible. The cohesion of the parquet elements between them is perfect, both horizontally and vertically.
