Description

La présente invention concerne le domaine des blocs modulaires flottants utilisables notamment pour la réalisation de pontons flottants.The present invention relates to the field of floating modular blocks which can be used in particular for the production of floating pontoons.

Plus spécialement l'invention concerne de tels blocs plus spécialement de forme parallélépipèdique et constitués d'un corps creux dont les parois sont en matière synthétique moulée, notamment par soufflage.More specifically, the invention relates to such blocks, more particularly of parallelepiped shape and consisting of a hollow body whose walls are made of molded synthetic material, in particular by blowing.

Il est entendu que l'invention n'est pas limitée à cette structure et concerne tous les blocs modulaires d'une densité permettant leur flottaison et destinés à constituer, notamment par leur assemblage, des structures flottantes.It is understood that the invention is not limited to this structure and relates to all modular blocks of a density allowing their flotation and intended to constitute, in particular by their assembly, floating structures.

Il est connu par le brevet français publié 2 116 846 de prévoir sur la face inférieure de blocs flottants une concavité, dimensionnée, selon ce document antérieur, en forme de cloche, de façon à emmagasiner une réserve d'air jouant alors le rôle d'amortisseur des mouvements vers le bas du bloc par compression de la réserve d'air.It is known from the published French patent 2 116 846 to provide on the underside of floating blocks a concavity, dimensioned, according to this prior document, in the shape of a bell, so as to store an air reserve while playing the role of damper for downward movement of the block by compression of the air reserve.

L'invention retient sans doute le principe général d'une face inférieure concave mais en empêchant toute présence d'air dans la concavité par une conformation et un dimensionnement approprié et en vue d'obtenir essentiellement une stabilité du bloc moins pour résister aux mouvements d'enfoncement, comme dans le document antérieur cité, que pour limiter les mouvements parasites d'oscillation angulaire du bloc maintenu dans une position toujours voisine de l'horizontale.The invention undoubtedly retains the general principle of a concave underside but by preventing any presence of air in the concavity by an appropriate conformation and sizing and with a view to essentially obtaining a block stability less to resist the movements of sinking, as in the cited earlier document, only to limit the parasitic movements of angular oscillation of the block maintained in a position always close to the horizontal.

A cet effet l'invention concerne un élément modulaire flottant constitué d'un bloc parallélépipèdique notamment en matière synthétique du type dont la face inférieure destinée à être totalement immergée présente une configuration incurvée concave, la concavité étant orientée vers le milieu liquide, et caractérisé en ce que la dite face concave est en forme de calotte sphérique dont la flèche centrale est de dimension inférieure à 20% et de préférence inférieure à 10% du plus petit côté de ladite face.To this end, the invention relates to a floating modular element consisting of a parallelepipedal block in particular of synthetic material of the type whose lower face intended to be fully submerged has a concave curved configuration, the concavity being oriented towards the liquid medium, and characterized in that said concave face is in the form of a spherical cap whose central arrow is of dimension less than 20% and preferably less than 10% of the shortest side of said face.

De préférence ledit bloc modulaire est de section horizontale carrée et le bord circulaire de la concavité inférieure rejoint sensiblement le milieu de chacun des cotés de ladite face inférieure, les bords de ladite face étant ainsi sensiblement tangents à ladite calotte sphérique et ladite face inférieure étant prolongée dans chaque angle par une zone plane.Preferably said modular block is of square horizontal section and the circular edge of the lower concavity substantially meets the middle of each side of said lower face, the edges of said face thus being substantially tangent to said spherical cap and said lower face being extended. in each corner by a flat area.

Selon une autre caractéristique, la face supérieure dudit bloc, face orientée vers le zénith en position d'immersion, présente une configuration convexe parallèle à la concavité de la face inférieure, la face supérieure ainsi complémentaire de la face inférieure permettant la gerbabilité des blocs.According to another characteristic, the upper face of said block, face facing the zenith in the immersion position, has a convex configuration parallel to the concavity of the lower face, the upper face thus complementary to the lower face allowing the stackability of the blocks.

L'invention permet d'obtenir des blocs présentant une bonne stabilité individuelle en position immergée ; mais il est également essentiel dans la mise en oeuvre de structures flottantes utilisant les blocs flottants du type spécifié d'assurer la stabilité de l'ensemble des blocs assemblés et à cet effet l'invention concerne également un dispositif de verrouillage résistant aux sollicitations résultants des mouvements parasites et erratiques susceptibles d'affecter les blocs assemblés sous l'effet des éléments.The invention makes it possible to obtain blocks having good individual stability in the submerged position; but it is also essential in the implementation of floating structures using floating blocks of the specified type to ensure the stability of all of the assembled blocks and for this purpose the invention also relates to a locking device resistant to the stresses resulting from parasitic and erratic movements likely to affect the assembled blocks under the effect of the elements.

Il est déjà connu par le brevet français publié 2 150 133 de prévoir sur les arêtes verticales disposées à chaque angle du bloc modulaire à embase carrée des oreilles rayonnant en étoile et décalées en hauteur, de sorte que quatre blocs assemblés selon une arête voisine présentent leurs oreilles d'assemblage en superposition et chaque oreille présente un logement, les logements prévus au centre des oreilles étant colinéaires de façon à permettre l'insertion d'une clavette de verrouillage dans la position d'assemblage des blocs modulaires.It is already known from the published French patent 2,150,133 to provide on the vertical edges arranged at each angle of the modular block with square base ears radiating in a star and offset in height, so that four blocks assembled along a neighboring edge have their assembly ears superimposed and each ear has a housing, the housing provided in the center of the ears being collinear so as to allow the insertion of a locking key in the assembly position of the modular blocks.

Selon l'invention, la clavette cylindrique comporte à sa base quatre ergots répartis sur le pourtour cylindrique et espacés entre eux de 90°, ces ergots étant aptes à venir se positionner sous l'oreille d'assemblage inférieure, et les oreilles superposées comportent sur le pourtour de leur évidement central quatre encoches espacées à 90° et aptes à permettre le coulissement des quatres ergots précédents successivement dans chacune des oreilles, la rotation ultérieure de sensiblement 45° de la clavette assurant le positionnement desdits ergots sous la partie non encochée de l'oreille inférieure, les ergots se trouvant alors bloqués en assurant la sécurité et le blocage de la clavette de verrouillage dans sa position de blocage.According to the invention, the cylindrical key has at its base four pins distributed on the cylindrical periphery and spaced apart by 90 °, these pins being able to come to be positioned under the lower assembly ear, and the superimposed ears comprise on the periphery of their central recess four notches spaced at 90 ° and able to allow the sliding of the four preceding pins successively in each of the ears, the subsequent rotation of substantially 45 ° of the key ensuring the positioning of said pins under the notched part of the 'lower ear, the lugs then being blocked ensuring security and blocking of the locking key in its locking position.

Selon une autre caractéristique, la partie cylindrique de la clavette de verrouillage comporte, au dessus desdits ergots, des nervures profilées, espacées entre elles de 90° et décalées de 45° par rapport au positionnement desdits ergots, ces rainures coopérant avec des incurvations en creux disposées sur le pourtour intérieur des logements au centre des oreilles, récepteurs de ladite clavette, ces incurvations en creux étant intercalées entre les encoches précitées prévues pour l'insertion des ergots de blocage.According to another characteristic, the cylindrical part of the locking key comprises, above said lugs, profiled ribs, spaced apart by 90 ° and offset by 45 ° relative to the positioning of said lugs, these grooves cooperating with hollow bends arranged on the inner periphery of the housings in the center of the ears, receptors of said key, these recesses being inserted between the aforementioned notches provided for the insertion of the locking pins.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit et qui est donnée en rapport avec une forme de réalisation de l'invention présentée à titre d'exemple non limitatif.Other characteristics and advantages of the invention will emerge from the description which follows and which is given in relation to an embodiment of the invention presented by way of nonlimiting example.

La figure 1 représente une vue en coupe transversale d'un bloc selon l'invention.Figure 1 shows a cross-sectional view of a block according to the invention.

La figure 2 représente une vue en plan de la moitié du bloc précédent.Figure 2 shows a plan view of half of the previous block.

La figure 2a représente une vue agrandie de l'oreille représentée sur la figure 2.FIG. 2a represents an enlarged view of the ear represented in FIG. 2.

La figure 3 représente une vue en coupe verticale de la clavette de verrouillage.Figure 3 shows a vertical sectional view of the locking key.

Les figures 4, 5 et 6 représentent des vues en coupe horizontale de la clavette de la figure 3, respectivement selon les lignes IV-IV, V-V et VI-VI de ladite figure 3.FIGS. 4, 5 and 6 represent views in horizontal section of the key of FIG. 3, respectively along the lines IV-IV, V-V and VI-VI of said FIG. 3.

La figure 7 représente une vue de blocs assemblés en situation.FIG. 7 represents a view of blocks assembled in situation.

Selon la figure 1 et la figure 2, on voit représenté un bloc flottant modulaire et destiné, par assemblage des blocs modulaires entre eux, à réaliser une surface flottante permettant le passage des personnes ou des appareils.According to Figure 1 and Figure 2, there is shown a modular floating block and intended, by assembling modular blocks together, to achieve a floating surface allowing the passage of people or devices.

On voit que la face supérieure bombée 1 épouse un profil convexe orienté vers le zénith, auquel correspond sensiblement le profil concave 2a de la face inférieure 2, ce profil étant représenté en pointillé puisqu'il correspond à la partie intérieure de la face inférieure ; la ligne en trait plein 3 (figure 2) représente la face latérale 3', à laquelle la face inférieure se raccorde par sensiblement un quart de cylindre 4;dans chaque angle entre les lignes pointillées 2b (pourtour de la calotte sphérique) et les lignes pointillées 2c (bords de la face inférieure) où se trouve la zone plane 5.It can be seen that the domed upper face 1 follows a convex profile oriented towards the zenith, to which the concave profile 2a of the lower face 2 corresponds substantially, this profile being shown in dotted lines since it corresponds to the inner part of the lower face; the solid line 3 (FIG. 2) represents the lateral face 3 ′, to which the lower face is connected by substantially a quarter of a cylinder 4; in each angle between the dotted lines 2b (periphery of the spherical cap) and the lines dotted lines 2c (edges of the lower face) where the flat area is 5.

La concavité disposée sur la face immergée procure un effet de ventouse qui améliore la stabilité.The concavity arranged on the immersed face provides a suction cup effect which improves stability.

Par ailleurs, toute modification dans la position horizontale du bloc se traduit par une immersion plus importante d'un côté de ladite face immergée créant une poussée d'Archimède qui tend à rétablir et à rééquilibrer la position horizontale du cube.Furthermore, any modification in the horizontal position of the block results in a greater immersion on one side of said immersed face creating an Archimedes thrust which tends to restore and rebalance the horizontal position of the cube.

Enfin, la face supérieure bombée assure une évacuation rapide de l'eau susceptible de venir se déposer (vagues, pluies, embruns, etc.) sur ladite face, et en assurant un profil concave de la face inférieure correspondant au profil convexe de la face supérieure on obtient ainsi une parfaite gerbabilité des éléments et leur stabilité en position empilée, pour le stockage ou le transport.Finally, the curved upper face ensures rapid evacuation of the water likely to be deposited (waves, rain, spray, etc.) on said face, and by ensuring a concave profile of the lower face corresponding to the convex profile of the face. superior, we obtain perfect stackability of the elements and their stability in stacked position, for storage or transport.

Le bloc flottant comporte au niveau de chaque arête verticale une oreille d'assemblage, les quatre oreilles, venues du corps du bloc 11 et désignées par la référence 13, sont étagées en hauteur de façon à permettre la superposition de quatre oreilles venues de quatre blocs adjacents, ceci de façon connue en soi.The floating block comprises at each vertical edge an assembly ear, the four ears, coming from the body of the block 11 and designated by the reference 13, are stepped in height so as to allow the superposition of four ears coming from four blocks adjacent, this in a manner known per se.

Ainsi qu'on le voit sur la figure 2 et la figure 2A, les oreilles 13 comportent un logement central 14, les logements venant en superposition de façon colinéaire permettent l'engagement de la clavette de verrouillage 17 représentée à la figure 3.As can be seen in FIG. 2 and FIG. 2A, the lugs 13 comprise a central housing 14, the housings coming in superimposition in a collinear manner allow the engagement of the locking key 17 shown in FIG. 3.

Sur le pourtour intérieur de ce logement 14 on voit quatre encoches 15 opposées deux-à-deux et disposées par conséquent en croix sur le pourtour de l'évidement central, les encoches étant espacées de 90° ; entre deux encoches se trouve positionné et prévu un évidement ou incurvation en creux 16 ; de sorte que les évidements 16 sont également opposés deux-à-deux étant disposés en croix et décalés de 45° par rapport au positionnement des encoches.On the inner periphery of this housing 14 we see four notches 15 opposite in pairs and consequently arranged in a cross on the periphery of the central recess, the notches being spaced 90 ° apart; between two notches is positioned and provided a recess or recess 16; so that the recesses 16 are also opposite in pairs, being arranged in a cross and offset by 45 ° relative to the positioning of the notches.

La clavette de blocage 17 représentée à la figure 3 comporte une partie inférieure cylindrique 17a sur la base de laquelle sont disposés quatre ergots 18 (figure 4) aptes à s'engager successivement dans les encoches 15 disposées sur le pourtour des oreilles précédentes.The locking key 17 shown in Figure 3 has a cylindrical lower portion 17a on the base of which are arranged four pins 18 (Figure 4) adapted to engage successively in the notches 15 disposed on the periphery of the previous ears.

Une rotation légère de la clavette après son engagement assure le blocage par positionnement des ergots 18 sous l'oreille inférieure 13a, les ergots étant positionnés alors en dehors de leur encoche de passage ce qui assure un verrouillage de l'ensemble ; les quatres ergots 18 étant alors portants sur le pourtour de l'oreille inférieure 13a, on obtient une grande sécurité dans le blocage.A slight rotation of the key after its engagement ensures the locking by positioning of the lugs 18 under the lower ear 13a, the lugs then being positioned outside their passage notch which ensures locking of the assembly; the four pins 18 then being bearing on the periphery of the lower ear 13a, great security is obtained in blocking.

Le verrouillage sous la dernière oreille 13a positionne le blocage environ à mi hauteur du bloc, là ou les débattements sont au minimum, que l'interface entre deux blocs s'ouvre vers le haut ou vers le bas ; de plus l'ergot pour se dégager devra traverser les quatre oreilles superposées ce qui rend le dégagement improbable sinon impossible.The locking under the last ear 13a positions the blocking about halfway up the block, where the deflections are at a minimum, whether the interface between two blocks opens up or down; moreover, the lug to disengage will have to cross the four superimposed ears, which makes disengagement improbable if not impossible.

Par ailleurs, pour assurerun complément de verrouillage, le corps cylindrique 17 comporte des rainures profilées verticales 19 (figure 5) qui sont décalées de 45° par rapport au positionnement des ergots ; ces rainures verticales peuvent également pénétrer dans les logements au centre des oreilles en passant à force dans les évidement 16 prévus sur le pourtour des logements 14 entre deux encoches 15.Furthermore, to ensure additional locking, the cylindrical body 17 has vertical profiled grooves 19 (FIG. 5) which are offset by 45 ° relative to the positioning of the pins; these vertical grooves can also penetrate into the housings in the center of the ears by forcing through the recesses 16 provided on the periphery of the housings 14 between two notches 15.

Lors de la rotation (de l'ordre de 45°) de la clavette de blocage, les rainures profilées 19 viennent se loger dans une encoche 15 assurant ainsi un effet de verrouillage empêchant la clavette de tourner sur elle-même et de s'éjecter.During rotation (of the order of 45 °) of the locking key, the profiled grooves 19 are housed in a notch 15 thus ensuring a locking effect preventing the key from turning on itself and ejecting itself .

Au niveau supérieur de la clavette et transitant vers la partie supérieure tronconique ou pyramidale, pointe en bas, une partie de forme générale cylindrique de plus grand rayon comporte également des rainures plus importantes 10 qui viennent s'engager dans les logements récepteurs 20 prévus sur la partie supérieure de l'arête des blocs assemblées entre eux.At the upper level of the key and passing towards the frusto-conical or pyramidal upper part, point downward, a generally cylindrical part of larger radius also has larger grooves 10 which engage in the receiving housings 20 provided on the upper part of the edge of the blocks assembled together.

Bien évidemment, les évidements 16 ont une profondeur vers l'extérieur très inférieure à la profondeur des encoches 15, de même que les rainures 19 ont une épaisseur très inférieure à celle des ergots 18.Obviously, the recesses 16 have a depth towards the outside much less than the depth of the notches 15, just as the grooves 19 have a thickness much less than that of the lugs 18.
