Description

L'invention concerne un plancher ou autre surface analogue comprenant: d'une part, une ossature formée d'éléments assemblés entre eux et, d'autre part, des dalles maintenues en position sur ladite ossature par une pluralité d'organes de fixation disposés sous leurs sous-faces, de préférence suivant deux ou plus de deux alignements et dont la forme coopère avec celle des éléments de l'ossature.The invention relates to a floor or other similar surface comprising: on the one hand, a frame formed of elements assembled together and, on the other hand, slabs held in position on said frame by a plurality of fixing members arranged beneath their undersides, preferably in two or more than two alignments, the shape of which cooperates with that of the elements of the frame.

Selon un exemple d'application particulièrement intéressant, l'invention est destinée à autoriser le montage et de démontage commodes, rapides et sans aucun outil, de planchers ou dallages de nature diverse tels que sols de tentes de camping, pourtours de piscines, accès à la mer, trottoirs, planchers de locaux industriels, etc... Ces exemples d'affectation intéressants ne sont cependant pas limitatifs, l'invention pouvant, plus généralement, être employée pour l'exécution de toute paroi ou surface horizontale, verticale ou inclinée telle que revêtement de murs, cloisons ou plafonds étagères, etc...According to a particularly interesting example of application, the invention is intended to allow the assembly and disassembly convenient, fast and without any tools, of floors or pavements of various nature such as the grounds of camping tents, swimming pool surrounds, access to the sea, sidewalks, floors of industrial premises, etc. These examples of interesting uses are not, however, limiting, the invention being able, more generally, to be used for the execution of any wall or surface that is horizontal, vertical or inclined. such as coating of walls, partitions or shelving ceilings, etc ...

On connaît déjà (FR-A-2.270.378) des planchers constitués par des dalles dont la face inférieure est munie de tétons et de tenons en forme de têtes de flèches fendues dans le milieu et qui, lors du montage desdits planchers s'engagent et se bloquent dans des rainures longitudinales que comportent des éléments d'ossature constitués par des poutrelles convenablement profilées. Un inconvénient de ce type de plancher est que, une fois montées, les dalles le sont d'une manière pratiquement définitive, et il est nécessaire de les briser lorsque l'on doit procéder à leur remplacement. Un autre inconvénient des planchers de ce genre est que, compte tenu du fait que les tétons et tenons dont sont munies les dalles forment des saillies de hauteur relativement importantes par rapport à l'épaisseur de ces dernières, l'empilage desdites dalles, par exemple en vue de leur stockage ou de leur expédition, nécessite un important volume. D'autre part, l'empilage des dalles peut provoquer la cassure des tétons ou tenons des dalles inférieures sous le poids des dalles superposées.We already know (FR-A-2,270,378) floors consisting of slabs whose underside is provided with pins and tenons in the form of arrow heads split in the middle and which, during the mounting of said floors engage and are blocked in longitudinal grooves which comprise framework elements constituted by suitably profiled beams. A disadvantage of this type of floor is that, once fitted, the tiles are almost completely finished, and it is necessary to break them when they have to be replaced. Another disadvantage of such floors is that, taking into account the fact that the nipples and tenons with which the slabs are provided form projections of relatively large height relative to the thickness of the latter, the stacking of said slabs, for example for storage or shipment, requires a large volume. On the other hand, stacking the slabs can cause the nipples or tenons of the lower slabs to break under the weight of the superimposed slabs.

L'invention a notamment pour but de remédier aux inconvénients susmentionnés.The object of the invention is in particular to remedy the aforementioned drawbacks.

Le plancher selon l'invention est principalement remarquable par le fait que ledit plancher ou autre surface est démontable, que ladite ossature est formée d'éléments tubulaires susceptibles d'être séparés, et en ce que les organes de fixation dont sont munies les dalles, sont constitués par des clips ou pinces élastiques comprenant deux branches flexibles disposées en vis-à-vis et dont les extrémités tendent à se rapprocher sous l'effet de leur élasticité après avoir été écartées, de façon à enserrer lesdits éléments tubulaires et à permettre de désolidariser lesdites dalles des ces derniers, par simple traction.The floor according to the invention is mainly remarkable by the fact that said floor or other surface is removable, that said frame is formed of tubular elements capable of being separated, and in that the fixing members with which the slabs are provided, consist of elastic clips or clamps comprising two flexible branches arranged opposite and whose ends tend to approach under the effect of their elasticity after being separated, so as to grip said tubular elements and to allow separate said slabs from the latter, by simple pulling.

Grâce à ce mode d'exécution, les dalles peuvent être aisément et quasi instantanément fixées sur l'ossature tubulaire par simple appui et pression. D'autre part, il est tout aussi facile et rapide des les désolidariser de ladite ossature, par simple traction.Thanks to this embodiment, the slabs can be easily and almost instantaneously fixed to the tubular framework by simple pressing and pressure. On the other hand, it is just as easy and quick to detach them from said frame, by simple traction.

Selon une autre caractéristique importante de l'invention, les dalles comportent des ouvertures la traversant dans leur épaisseur et débouchant entre les branches des clips ou pinces élastiques; une ouverture étant disposée au droit de chaque clip ou pince élastique, et ces ouvertures permettant le logement des clips des dalles superposées lorsque plusieurs dalles sont empilées.According to another important characteristic of the invention, the slabs have openings extending therethrough in their thickness and opening out between the branches of the clips or elastic clamps; an opening being arranged at the right of each clip or elastic clamp, and these openings allowing the accommodation of the clips of the overlapping slabs when several slabs are stacked.

Lavantage très intéressant découlant de ce mode de réalisation est que les dalles peuvent être empilées sous un encombrement réduit, sans aucun risque de cassure des clips ou pinces élastiques lesquels s'emboîtent parfaitement dans les ouvertures prévues dans l'épaisseur desdites dalles.The very advantageous advantage arising from this embodiment is that the tiles can be stacked in a small footprint, without any risk of breakage of the clips or elastic clamps which fit perfectly into the openings provided in the thickness of said tiles.

Ces buts et caractéristiques et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesquels:

  • La figure 1 est une vue de dessus d'une dalle du plancher ou autre surface démontable suivant l'invention.
  • La figure 2 est une vue en coupe suivant la ligne II-II de la figure 1.
  • La figure 3-est une vue de dessous de la dalle.

  • Figure 2 is a sectional view along line II-II of Figure 1.

On se réfère auxdits dessins pour décrire un exemple d'exécution avantageux, quoique nullement limitatif, l'étendue de la protection étant déterminée par la teneur des revendications, du plancher ou autre surface démontable qui fait l'objet de l'invention. Ce plancher comprend une dalle 1 qui est avantageusement moulée d'une seule pièce en toute matière plastique convenable présentant la rigidité requise et une certaine élasticité.Reference is made to said drawings to describe an advantageous embodiment, although in no way limitative, the extent of protection being determined by the content of the claims, of the floor or other removable surface which is the subject of the invention. This floor comprises a slab 1 which is advantageously molded in one piece from any suitable plastic material having the required rigidity and a certain elasticity.

Elle peut avoir une forme carrée, rectangulaire ou autre.It can have a square, rectangular or other shape.

Lorsque les dalles sont affectées à l'exécution de planchers démontables, leur face supérieure comporte, de préférence, une pluralité d'aspérités 2, de forme circulaire ou autre, destinées à constituer une surface antidérapante.When the slabs are assigned to the execution of removable floors, their upper face preferably comprises a plurality of asperities 2, of circular or other shape, intended to constitute a non-slip surface.

Le face postérieure ou face inférieure de la dalle comporte, de manière intéressante, des nervures 3 et 4 entrecroisées ayant pour but d'augmenter sa rigidité. Les nervures extrêmes 3' et 4' d'épaisseur plus importante sont disposées au droit des bords de la dalle et constituent en encadrement ou bordure entourant complètement la dalle proprement dite.The posterior face or lower face of the slab advantageously comprises crisscrossed ribs 3 and 4 intended to increase lie about its rigidity. The extreme ribs 3 'and 4' of greater thickness are arranged in line with the edges of the slab and constitute a frame or border completely surrounding the slab itself.

Suivant l'invention, ladite face postérieure ou face inférieure de la dalle est dotée d'une pluralité de clips ou pinces élastiques 5 avantageusement moulés d'une seule pièce avec ladite dalle. Suivant l'exemple illustré, la dalle comporte six clips ou pinches élastiques 5 s'étendant au-delà de sa sous-face 6 èt répartis suivant trois rangées ou alignements de deux clips espacées d'une distance 1 déterminant l'écartement des éléments tubulaires parallèles 7 de l'ossature sur laquelle ladite dalle est destinée à être positionnée par simple appui et pression.According to the invention, said rear face or lower face of the slab is provided with a plurality of elastic clips or clips 5 advantageously molded in one piece with said slab. According to the example illustrated, the slab comprises six elastic clips or pinches 5 extending beyond its underside 6 and distributed in three rows or alignments of two clips spaced apart by a distance 1 determining the spacing of the tubular elements parallel 7 of the frame on which said slab is intended to be positioned by simple pressing and pressure.

Chaque clip ou pince élastique 5 est constitué par une paire de branches flexibles 5a disposées en vis-à-vis et convergeant symètrique- ment, au-delà de ladite sous-face 6, en direction de leur extrémité libre (figure 4). De la sorte, lors de l'appui de la dalle sur les éléments tubulaires de l'ossature, les extrémités des branches 5a des clips 5 s'écartent des leur position de repos et se resserrent ensuite autour desdits éléments par l'effet de leur élasticité. Sa fixation sur ladite ossature est donc quasi instantanée, et il est tout aussi facile et rapide de la désolidariser de cette dernière, par simple traction.Each clip or elastic clamp 5 is constituted by a pair of flexible branches 5a arranged opposite and symmetrically converging, beyond said underside 6, in the direction of their free end (FIG. 4). In this way, when the slab rests on the tubular elements of the framework, the ends of the branches 5a of the clips 5 deviate from their rest position and then tighten around said elements by the effect of their elasticity. Its attachment to said frame is therefore almost instantaneous, and it is just as easy and quick to separate it from the latter, by simple traction.

Afin d'augmenter sa robustesse, la base de chaque clip ou pince élastique est constituée par un cadre 8 de hauteur identique à celle des nervures de renforcement 3 et 4 et formé, partiellement ou totalement, par lesdites nervures; tandis que des renforts 9 ayant, par exemple, une échancrure en arc de cercle, ou autre forme correspondant au profile des éléments 7 de l'ossature, relie, latéralement, la base de chaque branche flexible 5a à deux côtés parallèles dudit cadre.In order to increase its robustness, the base of each clip or elastic clamp is constituted by a frame 8 of height identical to that of the reinforcing ribs 3 and 4 and formed, partially or totally, by said ribs; while reinforcements 9 having, for example, a notch in an arc, or other shape corresponding to the profile of the elements 7 of the frame, connects, laterally, the base of each flexible branch 5a to two parallel sides of said frame.

Selon une caractéristique importante de l'invention, la dalle comporte une pluralité d'ouvertures 10 traversant sont épaisseur et débouchant entre les branches 5a des clips ou pinces élastiques 5. Le nombre de ces ouvertures 10, de forme rectangulaire ou autre, correspond à celui des clips ou pinces élastiques 5 et chacune d'elles est donc disposée au droit d'un clip ou pince élastique. De cette façon, lorsque les dalles sont superposées, les clips ou pinces élastiques 5 d'une dalle s'emboîtent dans les ouvertures 10 de la dalle superposée (figure 6) ou sous-jacente, suivant le sens de l'empilage. On obtient ainsi un auto-centrage des dalles empilées sous un volume réduit, un parfait équilibre de l'empilage, en même temps qu'une très bonne protection des organes de fixation (clips ou pinces élastiques 5) desdites dalles. A ce sujet, on observe que les pinces élastiques ont, sur leur portion s'étendant au-delà de la sous-face 6, et sur une portion de même hauteur délimitée par l'entrée des ouvertures 10, respectivement, des pentes externes 5b et internes 5c, identiques, de façon à s'emboîter parfaitement. D'autre part, la portion des pinces élastiques d'étendant au-delà de la sous-face 6 a une hauteur supérieure à celle des dalles, de sorte que, lorsque plusieurs dalles sont superposées, les pinces élastiques d'une dalle pénètrent à l'intérieur des deux dalles superposées ou sous-jacentes; les alignements de pinces élastiques emboîtées constituant ainsi de robustes points d'ancrage à l'intérieur de l'empilage.According to an important characteristic of the invention, the slab has a plurality of openings 10 passing through are thick and emerging between the branches 5a of elastic clips or clamps 5. The number of these openings 10, of rectangular or other shape, corresponds to that elastic clips or clips 5 and each of them is therefore arranged in line with an elastic clip or clip. In this way, when the slabs are superimposed, the elastic clips or clips 5 of a slab fit into the openings 10 of the superimposed slab (Figure 6) or underlying, depending on the direction of stacking. One thus obtains a self-centering of the tiles stacked under a reduced volume, a perfect balance of the stacking, at the same time as a very good protection of the fixing members (clips or elastic clamps 5) of said tiles. In this regard, it is observed that the elastic clamps have, on their portion extending beyond the underside 6, and on a portion of the same height delimited by the entry of the openings 10, respectively, external slopes 5b and internal 5c, identical, so as to fit perfectly. On the other hand, the portion of the elastic clamps extending beyond the underside 6 has a height greater than that of the slabs, so that, when several slabs are superimposed, the elastic clamps of a slab penetrate at the interior of the two overlapping or underlying slabs; the alignments of nested elastic clips thus constituting robust anchoring points inside the stack.

La dalle selon l'invention comporte encore des languettes 11 réparties sur sa périphérie, par exemple à raison de deux languettes par côté. Ces languettes sont solidaires de la base de l'encadrement ou bordure 3'-4' de la dalle. D'autre part, une encoche 12 est ménagée, à la base dudit encadrement, à proximité de chaque languette 11, et à la suite de cette dernière. Les encoches 12 ont une hauteur et une longueur à peine supérieures à celles des languettes 11 afin d'autoriser le logement desdites languettes. Dans ce but, et comme le montre la figure 3, les languettes et les encoches de deux côtés parallèles de la dalle, ont une position inversée, de façon que les languettes des côtés attenants de deux dalles contigües puissent se loger dans les encoches dont sont pourvus lesdits côtés.The slab according to the invention also includes tongues 11 distributed over its periphery, for example at the rate of two tongues per side. These tongues are integral with the base of the frame or border 3'-4 'of the slab. On the other hand, a notch 12 is formed, at the base of said frame, near each tongue 11, and following the latter. The notches 12 have a height and a length barely greater than those of the tongues 11 in order to allow the housing of said tongues. For this purpose, and as shown in FIG. 3, the tongues and the notches on two parallel sides of the slab have an inverted position, so that the tongues on the adjoining sides of two contiguous slabs can be housed in the notches of which are provided on said sides.

Cette disposition permet de réaliser un emboîtement réciproque des dalles entre elles, lequel, en combinaison avec le pinçage exercé par les clips 5, assure la bonne tunue desdites dalles sur l'armature 7.This arrangement enables reciprocal interlocking of the slabs with one another, which, in combination with the clamping exerted by the clips 5, ensures the correct tuning of said slabs on the frame 7.
