Description

La présente invention concerne un support adaptable destiné à soutenir et à bloquer, aussi bien verticalement que transversalement, des panneaux polygonaux assemblés bord à bord pour constituer des planchers démontables, par exemple de scène, de podium, d'estrade, etc. L'invention concerne aussi un système de plancher démontable faisant usage de tels supports.The present invention relates to an adaptable support intended to support and block, both vertically and transversely, polygonal panels assembled edge to edge to form removable floors, for example stage, podium, platform, etc. The invention also relates to a removable floor system making use of such supports.

Dans les planchers démontables ainsi constitués, chaque panneau était jusqu'à présent muni d'un piètement complet et-donc supporté de façon indépendante des panneaux adjacents. Il en résultait, au droit des noeuds de juxtaposition de plusieurs panneaux -c'est-à-dire en fait sous la plus grande partie du plancher-, une multiplication des poteaux de soutien qui, non seulement était coûteuse en matériel et en temps de montage ou de démontage, mais encore ne permettait pas de façon facile, de réaliser un plancher approximativement nivelé au-dessus d'un sol accidenté.In the removable floors thus formed, each panel has hitherto been provided with a complete base and therefore supported independently of the adjacent panels. This resulted, in the right of the juxtaposition nodes of several panels - that is to say in fact under most of the floor -, a multiplication of support posts which, not only was costly in material and time assembly or disassembly, but still did not allow in an easy way, to achieve a roughly leveled floor above uneven ground.

L'invention a essentiellement pour but de remédier à ces inconvénients des dispositifs de l'art antérieur et de proposer un support de panneaux ainsi qu'un système de plancher démontable qui donnent mieux satisfaction, dans toute la mesure du possible, que les supports et les systèmes actuellement connus.The object of the invention is essentially to remedy these drawbacks of the devices of the prior art and to propose a support for panels as well as a removable floor system which give better satisfaction, as far as possible, than the supports and currently known systems.

Selon un premier aspect de l'invention, un support agencé conformément à l'invention se caractérise en ce qu'il comprend une tête de forme prismatique possédant plusieurs faces devant, en position d'utilisation, être approximativement verticales, au moins un doigt de soutien et de blocage destiné à être fixé, à l'aide de moyens de fixation, sur ladite tête, et des moyens-de réception prévus sur chaque face de la tête agencés pour recevoir et bloquer en position fonctionnelle correcte, en coopération avec les susdits moyens de fixation, un doigt de manière telle que, en position d'utilisation du support, ce doigt s'étende approximativement verticalement et fasse saillie, de façon décalée latéralement, au-delà de la tête.According to a first aspect of the invention, a support arranged in accordance with the invention is characterized in that it comprises a prismatic head having several faces which, when in use, are approximately vertical, at least one finger support and blocking intended to be fixed, by means of fixing, on said head, and receiving means provided on each face of the head arranged to receive and block in correct functional position, in cooperation with the above-mentioned fixing means, a finger so that, in the position of use of the support, this finger extends approximately vertically and protrudes, in a laterally offset manner, beyond the head.

Grâce à cette disposition, il est possible de placer ce support à un noeud de juxtaposition de plusieurs panneaux (c'est-à-dire au point de juxtaposition des angles de plusieurs panneaux), ce support unique soutenant et bloquant à lui seul les angles adjacents des panneaux juxtaposés. En outre, ce support est adaptable de façon aisée et sans outillage particulier, à chaque configuration, en fonction du nombre de panneaux juxtaposés au noeud considéré.Thanks to this arrangement, it is possible to place this support at a juxtaposition node of several panels (that is to say at the point of juxtaposition of the angles of several panels), this single support supporting and blocking the angles on its own. adjacent panels juxtaposed. In addition, this support is easily adaptable and without special tools, to each configuration, depending on the number of panels juxtaposed at the node considered.

Dans un mode de réalisation préféré, la tête présente la forme approximative d'un parallélépipède rectangle, avec quatre faces principales munies de moyens de réception d'un doigt.In a preferred embodiment, the head has the approximate shape of a rectangular parallelepiped, with four main faces provided with means for receiving a finger.

Avantageusement, les moyens de réception d'un doigt comprennent, d'une part sur chaque face principale de la tête, un bossage prismatique saillant et, d'autre part sur le doigt, un évidement prismatique de forme complémentaire de celle du bossage.Advantageously, the means for receiving a finger comprise, on the one hand on each main face of the head, a projecting prismatic boss and, on the other hand on the finger, a prismatic recess of shape complementary to that of the boss.

Un mode de réalisation simple consiste à prévoir les moyens de fixation de chaque doigt sous forme de moyens à vis.A simple embodiment consists in providing the means for fixing each finger in the form of screw means.

De préférence, les doigts sont au moins de deux types différents possédant respectivement deux longueurs différentes, ce grâce à quoi il est possible de réaliser des planchers avec gradins.Preferably, the fingers are of at least two different types having respectively two different lengths, whereby it is possible to make floors with steps.

Pour réaliser des planchers ou portions de planchers peu surélevés.au-dessus du sol, on prévoit des têtes munies d'une embase plane destinée à assurer leur appui sur le sol.To make floors or portions of floors slightly raised above the ground, heads are provided with a flat base intended to ensure their support on the ground.

Par contre, pour réaliser des planchers ou portions de plancher notablement surélevés au-dessus du sol, on prévoit que la tête est fixée au sommet d'un poteau de soutien de hauteur adaptée. La tête est alors évidée intérieurement par un logement axial, s'étendant approximativement verticalement dans la position d'utilisation du support, et ouvert vers le bas, ce logement étant dimensionné, notamment pour ce qui concerne sa hauteur et ses dimensions transversales, notamment son diamètre, pour recevoir l'extrémité du susdit poteau de soutien.On the other hand, to make floors or portions of floor markedly raised above the ground, provision is made for the head to be fixed to the top of a post. adapted height support. The head is then hollowed out internally by an axial housing, extending approximately vertically in the position of use of the support, and open downwards, this housing being dimensioned, in particular as regards its height and its transverse dimensions, in particular its diameter, to receive the end of the above support post.

Selon un second aspect de l'invention, un système de plancher démontable conforme à l'invention se caractérise en ce qu'il comprend : des supports conformes à l'invention tels que précédemment décrits ; des poteaux pour porter à leur extrémité libre au moins un certain nombre de ces supports ; et des panneaux polygonaux possédant, dans leurs angles, des cavités pratiquées dans leur face inférieure et ouvertes vers le bas, ces cavités étant dimensionnées pour recevoir les extrémités des doigts des supports et pour reposer verticalement sur lesdites extrémités.According to a second aspect of the invention, a removable floor system according to the invention is characterized in that it comprises: supports according to the invention as previously described; posts for carrying at their free end at least a certain number of these supports; and polygonal panels having, in their angles, cavities formed in their lower face and open downwards, these cavities being dimensioned to receive the ends of the fingers of the supports and to rest vertically on said ends.

Grâce aux différentes dispositions de l'invention, il est possible de constituer des planchers de scène, podium, estrade, etc., avec une grande économie de matériels et donc de poids puisqu'en principe les éléments de soutien sont métalliques, d'où des coûts moindres à l'achat et à l'utilisation, en même temps que sont obtenus divers avantages d'utilisation, en particulier un positionnement relatif, en particulier bord à bord, correct en niveau des différents panneaux assemblés.Thanks to the various arrangements of the invention, it is possible to constitute stage floors, podiums, platforms, etc., with great savings in materials and therefore in weight since in principle the support elements are metallic, hence lower purchase and use costs, at the same time as various advantages of use are obtained, in particular a relative positioning, in particular edge to edge, correct in terms of the various assembled panels.

L'invention sera mieux comprise à la lecture de la description détaillée qui suit d'un mode de réalisation préféré, donné uniquement à titre d'exemple illustratif, sans aucun caractère limitatif. Dans cette description, on se réfère aux dessins annexés sur lesquels :

  • - La figure 1 est une vue en coupe verticale d'un support conforme à l'invention, représenté en position fonctionnelle dans une des configurations possibles ;
  • - La figure 2 est une vue de dessous de l'un des éléments du support de la fig. l ; et
  • - La figure 3 est un exemple de plancher avec gradins qu'il est possible de constituer avec le support de l'invention.
The invention will be better understood on reading the following detailed description of a preferred embodiment, given solely by way of illustrative example, without any limiting character. In this description, reference is made to the appended drawings in which:
  • - Figure 1 is a vertical sectional view of a support according to the invention, shown in the functional position in one of the possible configurations;
  • - Figure 2 is a bottom view of one of the elements of the support of FIG. l; and
  • - Figure 3 is an example of a floor with steps that it is possible to form with the support of the invention.

En se référant tout d'abord aux figures 1 et 2, le support de l'invention comprend essentiellement une tête de support 1 et au moins un (en général plusieurs) doigt de support et de blocage 2 destiné à coopérer avec des panneaux de plancher 3 d'une manière qui sera expliquée ultérieurement.Referring first to Figures 1 and 2, the support of the invention essentially comprises a support head 1 and at least one (in general several) support and locking finger 2 intended to cooperate with floor panels 3 in a manner which will be explained later.

La tête de support 1 présente la forme générale d'un manchon tubulaire fermé à sa partie supérieure, présentant un évidement cylindrique intérieur 4 et possédant extérieurement une forme prismatique (en 5). Eventuelle- ment, comme dans l'exemple représenté, la partie prismatique (partie supérieure) 5 se prolonge vers le bas par une partie d'emmanchement 6 extérieurement cylindrique de révolution destinée, par exemple, à être emmanchée sur un poteau tubulaire 7 (représenté en trait mixte à la fig. 2). La zone de liaison entre les parties supérieure 5 et inférieure 6 peut être extérieurement agencée sous forme d'une saillie périphérique 8, continue, sur laquelle viennent prendre appui les extrémités inférieures des doigts, comme cela est visible à la fig. l.The support head 1 has the general shape of a tubular sleeve closed at its upper part, having an internal cylindrical recess 4 and having externally a prismatic shape (at 5). Optionally, as in the example shown, the prismatic part (upper part) 5 extends downwards by an externally cylindrical fitting part 6 of revolution intended, for example, to be fitted on a tubular post 7 (shown in dashed line in Fig. 2). The connection zone between the upper 5 and lower 6 parts can be externally arranged in the form of a continuous peripheral projection 8, on which the lower ends of the fingers come to bear, as can be seen in FIG. l.

La forme de la partie prismatique.5, et en partie le nombre de ses faces et les angles mutuels entre les faces, sont déterminés par le nombre et la forme des panneaux de plancher juxtaposés qui doivent être soutenus. En principe, les panneaux en question sont rectangulaires et, à chaque noeud de juxtaposition, se trouvent au maximum quatre angles de panneaux à soutenir. Dans ce contexte, la partie supérieure 5 possède extérieurement la forme d'un parallélépipède rectangle, à faces rectangulaires orthogonales 9.The shape of the prismatic part. 5, and in part the number of its faces and the mutual angles between the faces, are determined by the number and the shape of the juxtaposed floor panels which must be supported. In principle, the panels in question are rectangular and, at each juxtaposition node, there are a maximum of four angles of panels to be supported. In this context, the upper part 5 has the external shape of a rectangular parallelepiped, with orthogonal rectangular faces 9.

Chacune des faces 9 porte un bossage saillant 10 de forme pyramidale à section rectangulaire allongée. En outre, la partie supérieure 5 est munie de deux paires de perçages diamétraux il centrés sur les bossages 10.Each of the faces 9 carries a projecting boss 10 of pyramidal shape with an elongated rectangular section. In addition, the upper part 5 is provided with two pairs of diametric holes 11 centered on the bosses 10.

Bien que la tête de support qui vient d'être décrite semble devoir correspondre à la structure la plus couramment utilisée, il est possible de constituer des têtes un peu différentes (non visibles à la fig. 1) ; ces têtes de support de type court comportent une partie prismatique 5 analogue à celle précédemment décrite, mais elles ne possèdent pas de partie inférieure d'emmanchement 6 : sensiblement au niveau de la saillie annulaire 8, elle repose sur une plaque d'appui ou semelle à laquelle elle est fixée mécaniquement (par exemple par soudure).Although the support head which has just been described seems to have to correspond to the most commonly used structure, it is possible to form slightly different heads (not visible in FIG. 1); these short type support heads include a prismatic part 5 similar to that previously described, but they do not have a lower fitting part 6: substantially at the level of the annular projection 8, it rests on a support plate or sole to which it is mechanically fixed (for example by welding).

Pour les têtes de support de type long (représenté à la fig. 1), le positionnement à la hauteur convenable est assuré en utilisant des poteaux 7 de hauteur appropriée, éventuellement réglable (voir fig. 3).For long type support heads (shown in fig. 1), positioning at the correct height is ensured by using posts 7 of appropriate height, possibly adjustable (see fig. 3).

Pour ce qui est maintenant des doigts de support et de blocage 2, ils présentent eux aussi deux régions axiales distinctes ; une région supérieure 12 servant au support et au blocage proprement dits d'un panneau de plancher 3 et une région inférieure 13 servant à la fixation dudit doigt sur la tête de support 1.As for the support and locking fingers 2, they too have two separate axial regions; an upper region 12 serving for the actual support and blocking of a floor panel 3 and a lower region 13 serving for fixing said finger to the support head 1.

La région supérieure 12 est agencée sous forme d'un élément tubulaire 14 sensiblement cylindrique de révolution présentant un évidement intérieur 15, lui aussi sensiblement cylindrique de révolution, et à fond fermé. La face extérieure de l'extrémité libre de l'élément 14 présente un chanfrein conique 16 destiné à faciliter sa coopération avec le panneau 3.The upper region 12 is arranged in the form of a tubular element 14 which is substantially cylindrical of revolution having an internal recess 15, which is also substantially cylindrical of revolution, and with a closed bottom. The outer face of the free end of the element 14 has a conical chamfer 16 intended to facilitate its cooperation with the panel 3.

La région inférieure 13 se présente sous forme d'une cavité 17 de forme prismatique exactement complémentaire de la forme des bossages 10 de la tête de support 5. Le fond 18 de cette cavité est muni de deux perçages 19 destinés, en position de montage du doigt 2 sur la tête 5, à coïncider avec les perçages 11, pour que deux moyens de blocage (boulons, goupilles ou analogues) puissent y être engagés (non représentés).The lower region 13 is in the form of a prismatic cavity 17 exactly complementary to the shape of the bosses 10 of the support head 5. The bottom 18 of this cavity is provided with two holes 19 intended, in the mounting position of the finger 2 on head 5, to coincide with the holes 11, so that two locking means (bolts, pins or the like) can be engaged therein (not shown).

On peut remarquer que le fond 18 de la cavité 17 s'étend dans l'alignement de l'une des génératrices de l'élément tubulaire 14, de manière telle que ledit élément tubulaire 14 se trouve en encorbellement vers l'extérieur par rapport au fond 18. Des ailes extérieures de renfort 20 assurent la rigidification de l'ensemble.It can be noted that the bottom 18 of the cavity 17 extends in alignment with one of the generatrices of the tubular element 14, so that said tubular element 14 is cantilevered outward relative to the bottom 18. Outer reinforcing wings 20 ensure the stiffening of the assembly.

Les doigts de support et de blocage 2 peuvent être, par exemple, de deux types différents, analogues dans leur structure, mais différents l'un de l'autre par la longueur de l'élément tubulaire 12. Ces deux types de doigt ont été représentés sur la fig. 1, le doigt "court" 2A étant situé à droite et le doigt "long" 2B étant situé à gauche (les mêmes références numériques sont utilisées pour désigner les différentes parties de ces deux doigts). A titre d'exemple, la longueur de l'élément tubulaire 14A du doigt "court" 2A est d'environ 106 mm, tandis que la longueur de l'élément tubulaire 14B du doigt 2B est d'environ du double.The support and locking fingers 2 can be, for example, of two different types, analogous in their structure, but different from each other by the length of the tubular element 12. These two types of finger have been shown in fig. 1, the "short" finger 2A being located on the right and the "long" finger 2B being located on the left (the same reference numerals are used to designate the different parts of these two fingers). By way of example, the length of the tubular element 14A of the "short" finger 2A is approximately 106 mm, while the length of the tubular element 14B of the finger 2B is approximately double.

La fonction du support et de blocage des doigts 2 est assurée de la façon suivante.The function of the support and blocking of the fingers 2 is ensured in the following manner.

Chaque panneau de plancher 3 comprend une plaque 21 (en bois par exemple) notamment de forme rectangulaire, s'appuyant dans chacun de ses angles sur une pièce de coin métallique 22 (laquelle peut être solidarisée -par clouage ou vissage- à la plaque 21). La pièce de coin 22 présente un manchon tubulaire 23 saillant vers le bas et ayant un diamètre tubulaire intérieur correspondant approximativement au diamètre extérieur du doigt 2 pour pouvoir coiffer celui- ci. L'axe du manchon 23 est situé, par rapport aux bords de la pièce 22, de manière telle que, en position de montage de la pièce 22 sur le doigt 2, le bord de la pièce 23 s'étende jusqu'à proximité de l'axe la de la tête de support 1. On est ainsi assuré que deux panneaux voisins de même niveau ont leur bords correspondants pratiquement juxtaposés (comme représenté en trait mixte à la fig. 1). Dans le cas où les deux panneaux voisins sont supportés à des hauteurs différentes (formation en gradin), leurs bords correspondants sont situés pratiquement en alignement l'un au-dessus de l'autre (comme représenté à la fig. 1).Each floor panel 3 comprises a plate 21 (in wood for example) in particular of rectangular shape, resting in each of its angles on a metal corner piece 22 (which can be secured - by nailing or screwing - to the plate 21 ). The corner piece 22 has a tubular sleeve 23 projecting downward and having an inner tubular diameter corresponding approximately to the outer diameter of the finger 2 to be able to cap it. The axis of the sleeve 23 is located, with respect to the edges of the part 22, so that, in the mounting position of the part 22 on the finger 2, the edge of the part 23 extends as close as possible to the axis la of the support head 1. It is thus ensured that two neighboring panels at the same level have their corresponding edges practically juxtaposed (as shown in phantom in Fig. 1). In the case where the two neighboring panels are supported at different heights (tiered formation), their corresponding edges are situated practically in alignment one above the other (as shown in fig. 1).

Dans l'agencement qui vient d'être décrit, la pièce de coin 22 repose, par le fond de son manchon 23, contre l'extrémité libre de l'élément tubulaire 14 du doigt 2 -ce qui assure le support du panneau 3-, tandis que le manchon 23 emmanchée sur l'élément tubulaire 14 assure le blocage transversal du panneau 3. Une solida- risation (boulon, goupille) peut être prévue entre le manchon 23 et l'élément tubulaire 14 pour assurer en outre un blocage vertical de l'assemblage, l'organe de solidarisa- tion étant introduit dans le passage radial 6a (fig. 2).In the arrangement which has just been described, the corner piece 22 rests, by the bottom of its sleeve 23, against the free end of the tubular element 14 of the finger 2 - which ensures the support of the panel 3- , while the sleeve 23 fitted on the tubular element 14 ensures the transverse locking of the panel 3. A fastening (bolt, pin) can be provided between the sleeve 23 and the tubular element 14 to further ensure vertical locking of the assembly, the joining member being introduced into the radial passage 6a (FIG. 2).

Bien entendu, d'autres dispositions équivalentes peuvent être adoptées, telles que par exemple celle consistant en ce que le manchon 23 et/ou l'évidement tubulaire 15 soient mutuellement dimensionnées pour que le manchon 23 soit intérieur à l'évidement 15, ou bien celle consistant en ce que le manchon 23 fasse partie intégrante de la plaque 21 (notamment plaque constituée en matériau moulé).Of course, other equivalent arrangements can be adopted, such as for example that consisting of the sleeve 23 and / or the tubular recess 15 being mutually dimensioned so that the sleeve 23 is inside the recess 15, or else that consisting in that the sleeve 23 forms an integral part of the plate 21 (in particular plate made of molded material).

La tête de support 1 peut donc recevoir de un à quatre doigts 2, de l'un ou l'autre type (court ou long), en fonction du nombre de panneaux à supporter. A la figure 3 ont été réunies à titre d'exemple quelques configurations possibles de plancher faisant usage du support de l'invention. Sur cette figure 3, on a représenté un plancher avec gradins, constitué de panneaux identiques juxtaposés 3, soutenus par des supports de l'invention.The support head 1 can therefore receive from one to four fingers 2, of one or the other type (short or long), depending on the number of panels to be supported. In Figure 3 have been gathered by way of example some possible floor configurations using the support of the invention. In this Figure 3, there is shown a floor with steps, consisting of identical panels juxtaposed 3, supported by supports of the invention.

La partie de plancher 24 est située à ras du sol et les supports 25 sont du type "courts" précédemment décrits (partie supérieure pyramidale 5 directement montée sur une semelle d'appui au sol 26), munie de doigts d'un même type (en général du type court).The floor part 24 is located flush with the ground and the supports 25 are of the "short" type previously described (pyramidal upper part 5 directly mounted on a ground support sole 26), provided with fingers of the same type ( usually short).

La partie de plancher surélevé 27 est soutenue par des supports 28 avec partie inférieure d'emmanchement 6, fixés aux sommets de poteaux 7 avec réglages inférieurs 29. Tous les supports 28 soutenant la partie 27 sont équipés de doigts du même type (en général du type court). A la partie de plancher 27succèdent un premier gradin 30, puis un second gradin 31, supportas par des supports 28a munis respectivement de doigts des deux types (court et long) comme indiqué en regard de la fig. 1. Les poteaux 7' situés à la jonction des parties de plancher 30 et 31 sont plus hauts que les poteaux 7 supportant la partie de plancher 27.The raised floor part 27 is supported by supports 28 with lower fitting part 6, fixed to the post tops 7 with lower adjustments 29. All the supports 28 supporting part 27 are fitted with fingers of the same type (generally of the short type). At the floor part 27success a first step 30, then a second step 31, supported by supports 28a provided respectively with fingers of the two types (short and long) as indicated with reference to FIG. 1. The posts 7 'located at the junction of the floor parts 30 and 31 are higher than the posts 7 supporting the floor part 27.

Pour ce qui est plus particulièrement des supports 25 ou 28, ils sont équipés comme suit.As regards more particularly the supports 25 or 28, they are equipped as follows.

Ceux situés dans les angles des planchers (25' ou 28') n'ont à supporter qu'un seul angle dé panneau et sont donc équipés d'un doigt unique (de type court en général).Those located in the corners of the floors (25 'or 28') only have to support one angle of the panel and are therefore fitted with a single finger (generally of the short type).

Ceux situés en bordure des planchers (25", 28" ou 28a") ont à supporter deux angles de respectivement deux panneaux juxtaposés et sont donc équipés de deux doigts.Those located at the edge of the floors (25 ", 28" or 28a ") have to support two angles of respectively two juxtaposed panels and are therefore equipped with two fingers.

Enfin ceux (25'", 28"' ou 28a"') situés à un noeud de juxtaposition de quatre panneaux sont équipés de quatre doigts.Finally those (25 '", 28"' or 28a "') located at a juxtaposition node of four panels are equipped with four fingers.

Comme il va de soi et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus spécialement envisagés ; elle en embrasse, au contraire, toutes les variantes.As goes without saying and as it already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; on the contrary, it embraces all its variants.
