Description

Domaine TechniqueTechnical area

La présente invention porte sur le domaine de la fabrication de planchers de terrasse constitués d'une pluralité de lames de terrasse.The present invention relates to the field of the manufacture of terrace floors made up of a plurality of terrace boards.

Technique antérieurePrior technique

Traditionnellement, les lames de terrasse, qui peuvent être en bois naturel ou composite, sont fixées à un support. Ce dernier est généralement constitué de lambourdes constituant un treillis, qui ont été préalablement fixées sur le sol ou sur une dalle béton.Traditionally, decking boards, which can be made of natural or composite wood, are fixed to a support. The latter generally consists of joists constituting a trellis, which have been previously fixed to the ground or to a concrete slab.

Les lames de terrasses sont posées sur les lambourdes en étant disposées parallèlement les unes aux autres selon leurs longueurs, le plus souvent dans le sens de la largeur de la dalle béton. On forme ainsi un plancher constitué de lames parallèles.The decking boards are placed on the joists by being arranged parallel to each other along their lengths, most often in the direction of the width of the concrete slab. A floor consisting of parallel strips is thus formed.

Pour fixer les lames de terrasse aux lambourdes, il est connu d'utiliser des dispositifs de fixation, généralement appelés « clips », qui sont fixés aux lambourdes à l'aide de vis, et qui possèdent des ailettes venant s'engager dans des rainures ménagées le long des bords longitudinaux des lames en vis-à-vis.To fix the decking boards to the joists, it is known to use fixing devices, generally called "clips", which are fixed to the joists by means of screws, and which have fins which engage in grooves provided along the longitudinal edges of the blades vis-à-vis.

Il existe plusieurs types de dispositifs de fixation. Un exemple est décrit dans EP 3 106 585 . Il comprend une molette rotative par rapport à une embase, la molette venant s'engager dans la rainure de la lame de terrasse.There are several types of fastening devices. An example is described in EP 3 106 585 . It comprises a rotatable knob relative to a base, the knob engaging in the groove of the decking board.

Un autre exemple est décrit dans le document FR2864568 .Another example is described in the document FR2864568 .

On comprend que la portion de la lame qui est située sous la rainure vient s'engager entre l'ailette et le support.It is understood that the portion of the blade which is located under the groove engages between the fin and the support.

Il est par ailleurs connu que les lames de terrasse ont tendance à se dilater et gonfler lorsque l'humidité augmente, notamment à l'automne et en hiver.It is also known that decking boards tend to expand and swell when the humidity increases, especially in autumn and winter.

La dilatation des lames a également pour effet d'augmenter leur épaisseur, considérée selon une direction verticale.The expansion of the blades also has the effect of increasing their thickness, considered in a vertical direction.

Aussi, selon la saison à laquelle la terrasse est fabriquée, les lames présenteront des épaisseurs différentes. Si la terrasse est construite en période humide, il peut arriver que la portion de lame située sous la rainure soit trop épaisse pour être engagée entre l'ailette et le support.Also, depending on the season in which the terrace is made, the boards will have different thicknesses. If the terrace is built in wet weather, it may happen that the portion of the blade located under the groove is too thick to be engaged between the fin and the support.

Par ailleurs, il arrive que la position des rainures varient d'une lame à l'autre, et que certaines rainures soit plus hautes qu'attendues.Moreover, it happens that the position of the grooves vary from one blade to another, and that certain grooves are higher than expected.

Dans ce cas également, il peut être difficile d'engager la lame avec l'élément de maintien.Also in this case, it may be difficult to engage the blade with the holding element.

Le poseur doit alors rectifier lui-même la largeur de la rainure, ou bien mettre au rebut la lame défectueuse et en choisir une autre.The installer must then rectify the width of the groove himself, or else scrap the defective board and choose another one.

Enfin, il existe des modèles de lames de différentes épaisseurs, selon le type de bois ou de qualité de lames. Aussi, d'un modèle de lame à l'autre, la position des rainures peut varier. Cela oblige généralement le poseur à disposer de plusieurs types de dispositifs de fixation ayant des dimensions adaptées aux différents modèles de lames.Finally, there are models of blades of different thicknesses, depending on the type of wood or the quality of the blades. Also, from one blade model to another, the position of the grooves may vary. This generally requires the installer to have several types of fixing devices with dimensions adapted to the different models of blades.

Exposé de l'inventionDisclosure of Invention

Un but de l'invention est de remédier aux inconvénients précités en proposant un dispositif de fixation universel qui peut être utilisé avec des lames de différentes épaisseurs.An object of the invention is to remedy the aforementioned drawbacks by proposing a universal fixing device which can be used with blades of different thicknesses.

Pour ce faire, l'invention porte sur un dispositif de fixation selon la revendication 1 pour fixer à un support au moins une lame de terrasse ayant un bord longitudinal muni d'une rainure, le dispositif de fixation comportant :

  • une embase ayant une face supérieure, l'embase comportant au moins un premier organe de guidage faisant saillie perpendiculairement à la face supérieure selon une première direction, l'embase ayant une longueur, une largeur, et une hauteur ;
  • un boitier coopérant avec le premier organe de guidage en sorte que le boitier est monté coulissant par rapport à l'embase selon la première direction, le boitier ayant une longueur, une largeur et une hauteur ;
  • un élément de maintien monté au boitier et configuré pour être engagé au moins dans la rainure de la lame de terrasse, l'élément de maintien faisant saillie de part et d'autre du boitier selon la direction longitudinale de l'embase; et
  • un élément de verrouillage configuré pour solidariser le dispositif de fixation au support.
To do this, the invention relates to a fixing device according to claim 1 for fixing to a support at least one decking board having a longitudinal edge provided with a groove, the fixing device comprising:
  • a base having an upper face, the base comprising at least a first guide member projecting perpendicular to the upper face in a first direction, the base having a length, a width, and a height;
  • a box cooperating with the first guide member so that the box is mounted to slide relative to the base in the first direction, the box having a length, a width and a height;
  • a holding element mounted on the housing and configured to be engaged at least in the groove of the decking board, the holding element projecting from either side of the housing in the longitudinal direction of the base; and
  • a locking element configured to secure the fastening device to the support.

Le support est constitué de préférence de lambourdes, préalablement fixées au sol. Les lambourdes sont généralement des pièces de bois formant un treillis sur lesquelles sont montées les lames.The support preferably consists of joists, previously fixed to the ground. The joists are generally pieces of wood forming a trellis on which the boards are mounted.

L'embase forme un entretoise entre les lames et le support, ce qui permet une ventilation sous les lames, et aussi d'évacuer l'eau de pluie.The base forms a spacer between the slats and the support, which allows ventilation under the slats, and also to evacuate rainwater.

On comprend que le boitier du dispositif de fixation selon l'invention est mobile par rapport à l'embase selon la première direction. Lorsque l'embase est fixée au support, la première direction est généralement verticale.It is understood that the housing of the fixing device according to the invention is movable relative to the base in the first direction. When the base is fixed to the support, the first direction is generally vertical.

La distance entre l'élément de maintien et l'embase du dispositif de fixation peut donc être modifiée en déplaçant le boitier par rapport à l'embase selon la première direction le long de l'organe de guidage. De préférence, le dispositif de fixation présente une distance minimale dans laquelle le boitier vient au contact de l'embase. La distance maximale est quant à elle légèrement inférieure à la hauteur du premier organe de guidage de façon que l'organe de guidage reste engagé dans le boitier.The distance between the holding element and the base of the fixing device can therefore be modified by moving the box relative to the base in the first direction along the guide member. Preferably, the fixing device has a minimum distance in which the box comes into contact with the base. The maximum distance is itself slightly less than the height of the first guide member so that the guide member remains engaged in the housing.

Aussi, grâce à l'invention, l'écartement entre l'élément de maintien et la face supérieure de l'embase peut être ajustée en fonction de la hauteur de la rainure considérée depuis la face supérieure de l'embase, c'est-à-dire l'épaisseur de la portion de lame située sous la rainure.Also, thanks to the invention, the spacing between the retaining element and the upper face of the base can be adjusted according to the height of the groove considered from the upper face of the base, i.e. ie the thickness of the portion of the blade located under the groove.

En pratique, le poseur place tout d'abord l'embase au support, généralement une lambourde, puis engage le boitier avec le premier organe de guidage. Le poseur place ensuite au moins une lame, de préférence deux lames, sur l'embase de sorte que l'élément de maintien vienne s'introduire dans la(les) rainure(s) de la (les) lame(s). Le boitier se positionne alors de lui-même en hauteur par rapport à l'embase en coulissant le long de l'organe de guidage.In practice, the installer first places the base on the support, generally a sleeper, then engages the box with the first guide member. The fitter then places at least one slat, preferably two slats, on the base so that the holding element is inserted into the groove(s) of the slat(s). The box then positions itself in height relative to the base by sliding along the guide member.

Le poseur verrouille ensuite le boitier, l'embase et l'élément de maintien au support à l'aide de l'élément de verrouillage.The installer then locks the box, the base and the holding element to the support using the locking element.

L'élément de verrouillage exerce un effort sur l'élément de maintien, et par conséquent sur les lames, dirigés selon la première direction vers l'embase, de sorte que les lames sont plaquées contre l'embase. Dans le même temps, les lames plaquent l'embase contre le support.The locking element exerts a force on the holding element, and consequently on the blades, directed in the first direction towards the base, so that the blades are pressed against the base. At the same time, the blades press the base against the support.

Les lames sont alors fermement maintenues au support grâce au dispositif de fixation, qui s'est adapté à la position des rainures des lames.The blades are then firmly held to the support thanks to the fixing device, which has adapted to the position of the grooves of the blades.

Avantageusement, le premier organe de guidage est parallèle et distant de l'élément de verrouillage. Autrement dit, le premier organe de guidage est non-coaxial à l'élément de verrouillage.Advantageously, the first guide member is parallel to and remote from the locking element. In other words, the first guide member is non-coaxial with the locking element.

Avantageusement, considérée selon la direction longitudinale de l'embase, la face supérieure de l'embase comporte deux portions d'embase disposées de part et d'autre de l'organe de guidage, pour recevoir deux lames de terrasse, au moins une des portions d'embase comportant un évidement bordé par un bord périphérique pour recevoir une des lames.Advantageously, considered along the longitudinal direction of the base, the upper face of the base comprises two base portions arranged on either side of the guide member, to receive two blades terrace, at least one of the base portions comprising a recess bordered by a peripheral edge to receive one of the blades.

Un intérêt de l'évidement est d'améliorer l'évacuation de l'eau de pluie entre les lames et le support, et d'éviter ainsi une accumulation d'eau sous la terrasse qui est susceptible d'endommager les lames et/ou le support.One advantage of the recess is to improve the evacuation of rainwater between the boards and the support, and thus to avoid an accumulation of water under the terrace which is likely to damage the boards and/or the support.

De préférence, l'embase comporte un piètement, de préférence périphérique, qui est muni de patins.Preferably, the base comprises a base, preferably peripheral, which is provided with pads.

Les échancrures situées entre deux patins adjacents permettent d'améliorer encore l'évacuation de l'eau de pluie hors de l'embase.The notches located between two adjacent runners further improve the evacuation of rainwater from the base.

Avantageusement, l'embase comporte un orifice qui est traversant et qui s'étend selon une direction parallèle à la première direction, l'orifice étant conformé pour recevoir l'élément de verrouillage lorsque le dispositif de fixation est solidarisé au support.Advantageously, the base has an orifice which is through and which extends in a direction parallel to the first direction, the orifice being shaped to receive the locking element when the fixing device is secured to the support.

L'élément de verrouillage traverse ainsi l'embase par l'orifice. Ce dernier est situé de préférence au milieu de l'embase.The locking element thus passes through the base via the orifice. The latter is preferably located in the middle of the base.

L'embase est de préférence une pièce en pastique.The base is preferably a plastic part.

Selon un mode de réalisation préférentiel, l'embase comporte un second organe de guidage, les premier et second organes de guidage étant disposés de part et d'autre de l'orifice, de préférence selon la largeur de l'embase.According to a preferred embodiment, the base comprises a second guide member, the first and second guide members being arranged on either side of the orifice, preferably along the width of the base.

La présence de deux organes de guidage a pour effet d'éviter une rotation du boitier par rapport à l'embase. Un intérêt est de faciliter le montage du dispositif de fixation.The presence of two guide members has the effect of preventing rotation of the case relative to the base. An interest is to facilitate the assembly of the fixing device.

Les premier et second organes de guidage s'étendent depuis une partie de l'embase qui forme un pont reliant les deux bords longitudinaux de l'embase.The first and second guide members extend from a part of the base which forms a bridge connecting the two longitudinal edges of the base.

Avantageusement, le boitier comporte au moins une première cavité pour recevoir le premier organe de guidage. Cette cavité débouche préférentiellement dans une face inférieure du boitier. Elle constitue un logement pour le premier organe de guidage.Advantageously, the box comprises at least a first cavity to receive the first guide member. This cavity preferentially opens into a lower face of the case. It constitutes a housing for the first guide member.

De préférence, le boitier comporte une seconde cavité pour recevoir le second organe de guidage.Preferably, the box includes a second cavity to receive the second guide member.

Le premier organe de guidage présente préférentiellement la forme d'un ergot. Encore de préférence, l'ergot est cylindrique ou tronconique. On comprend que l'ergot est engagé dans la cavité lorsque le boitier est monté sur l'embase.The first guide member preferably has the shape of a lug. Still preferably, the lug is cylindrical or frustoconical. It is understood that the lug is engaged in the cavity when the box is mounted on the base.

De préférence, le premier organe de guidage est déformable. Pour ce faire, le premier organe de guidage est préférentiellement creux. Aussi, le premier organe de guidage peut s'écraser sur lui-même selon une direction d'écrasement perpendiculaire à la première direction en cas par exemple de dilatation horizontale des lames.Preferably, the first guide member is deformable. To do this, the first guide member is preferably hollow. Also, the first guide member can be crushed on itself in a direction of crushing perpendicular to the first direction in the event, for example, of horizontal expansion of the blades.

Avantageusement, le boitier comporte en outre un trou s'étendant selon la hauteur du boitier et qui est traversant, le trou étant conformé pour recevoir l'élément de verrouillage lorsque le dispositif de fixation est solidarisé au support.Advantageously, the box further comprises a hole extending along the height of the box and which is through, the hole being shaped to receive the locking element when the fixing device is secured to the support.

Le trou est donc traversé par l'élément de verrouillage lorsque le dispositif de fixation est solidarisé au support.The hole is therefore traversed by the locking element when the fastening device is secured to the support.

Avantageusement, le trou du boitier se trouve dans le prolongement de l'orifice de l'embase lorsque le boitier est monté à l'embase.Advantageously, the hole in the box is in the extension of the hole in the base when the box is mounted on the base.

Avantageusement, le trou est disposé entre les première et seconde cavités. Le trou se trouve sensiblement au milieu du boitier, considéré selon sa longueur.Advantageously, the hole is arranged between the first and second cavities. The hole is located substantially in the middle of the box, considered according to its length.

La longueur du boitier correspond sensiblement à la largeur de l'embase. La hauteur du boitier est légèrement supérieure à la hauteur du premier organe de guidage.The length of the box corresponds substantially to the width of the base. The height of the box is slightly greater than the height of the first guide member.

Avantageusement, l'élément de maintien est un insert, de préférence métallique, qui est fixé au boitier.Advantageously, the holding element is an insert, preferably metallic, which is fixed to the case.

Le boitier est préférentiellement en matière plastique. L'insert est quant à lui de préférence surmoulé avec le boitier.The case is preferably made of plastic. The insert is for its part preferably overmolded with the box.

L'insert métallique permet d'améliorer la robustesse du dispositif de fixation selon l'invention, par rapport à des dispositifs de fixation traditionnels dont l'élément de maintien est en plastique.The metal insert makes it possible to improve the robustness of the fixing device according to the invention, compared to traditional fixing devices whose holding element is made of plastic.

L'insert fait préférentiellement sailli de part et d'autre de la largeur du boitier. Les deux parties en saillie de l'insert forment des ailettes qui sont destinées à venir s'engager dans les rainures des lames.The insert preferably protrudes on either side of the width of the box. The two projecting parts of the insert form fins which are intended to engage in the grooves of the blades.

Avantageusement, l'élément de maintien présente la forme d'une plaquette munie d'une ouverture, l'ouverture étant conformé pour recevoir l'élément de verrouillage lorsque le dispositif de fixation est solidarisé au support.Advantageously, the holding element has the form of a plate provided with an opening, the opening being shaped to receive the locking element when the fixing device is secured to the support.

De façon préférentielle, l'insert présente la forme d'une plaquette. L'ouverture de la plaquette est de préférence alignée avec le trou du boitier.Preferably, the insert has the shape of a wafer. The opening of the plate is preferably aligned with the hole of the case.

Avantageusement, la plaquette fait saillie de part et d'autre des bords longitudinaux du boitier.Advantageously, the wafer protrudes on either side of the longitudinal edges of the case.

On comprend que l'élément de verrouillage est engagé successivement dans l'ouverture de la plaquette, le trou du boitier et l'orifice de l'embase avant d'être introduit dans le support.It is understood that the locking element is engaged successively in the opening of the wafer, the hole of the housing and the orifice of the base before being introduced into the support.

De préférence, le trou du boitier et l'ouverture de la plaquette sont coaxiaux, le trou du boitier étant en retrait radialement par rapport à l'ouverture, par quoi l'élément de verrouillage vient en appui contre la plaquette lorsque le dispositif de fixation est solidarisé au support.Preferably, the housing hole and the plate opening are coaxial, the housing hole being set back radially with respect to the opening, whereby the locking element bears against the plate when the fixing device is attached to the support.

L'élément de verrouillage comporte préférentiellement un corps longiligne, par exemple une tige filetée, terminée par une tête.The locking element preferably comprises an elongated body, for example a threaded rod, terminated by a head.

La tête de l'élément de verrouillage est conformée pour venir en appui contre la plaquette, préférentiellement contre l'insert métallique, lorsque le dispositif de fixation est fixé au support.The head of the locking element is shaped to bear against the plate, preferably against the metal insert, when the fixing device is fixed to the support.

L'élément de verrouillage, qui est préférentiellement métallique, exerce un effort sur l'insert métallique et non pas sur le boitier plastique, ce qui présente l'avantage de ne pas endommager le pastique du boitier en cas de serrage fort de l'élément de verrouillage.The locking element, which is preferably metallic, exerts a force on the metallic insert and not on the plastic case, which has the advantage of not damaging the plastic of the case in the event of strong tightening of the element locking.

Préférentiellement, la plaquette présente un bord latéral muni de griffes configurées pour venir en appui dans une paroi de la rainure de la lame.Preferably, the wafer has a lateral edge provided with claws configured to bear against a wall of the groove of the blade.

Plus précisément, les griffes sont inclinées vers une face inférieure du boitier. Autrement dit, les griffes sont inclinées vers l'embase, de préférence d'un angle d'environ 30°-45° par rapport au plan de la plaquette.More specifically, the claws are inclined towards an underside of the case. In other words, the claws are inclined towards the base, preferably at an angle of about 30°-45° relative to the plane of the wafer.

Grâce à cette conformation, les griffes viennent se planter dans la paroi inférieure de la rainure lors de la fixation du dispositif de fixation. Cette paroi inférieure s'étend dans un plan parallèle à la face supérieure de l'embase. Ces griffes ont pour fonction de réduire le jeu des lames dans un plan horizontal. Elles permettent aussi d'améliorer le plaquage des lames contre l'embase.Thanks to this conformation, the claws are planted in the lower wall of the groove when fixing the fixing device. This lower wall extends in a plane parallel to the upper face of the base. These claws have the function of reducing the play of the blades in a horizontal plane. They also make it possible to improve the plating of the blades against the base.

Avantageusement, la plaquette présente un rebord latéral incliné.Advantageously, the wafer has an inclined side edge.

Le rebord latéral est incliné par rapport au plan de plaquette ou présente un bourrelet. Il est préférentiellement opposé aux griffes.The side flange is inclined with respect to the plate plane or has a bead. It is preferentially opposed to claws.

Le rebord latéral incliné est adapté pour venir au contact d'une paroi de fond de la rainure de la lame dans lequel il est engagé, notamment lors d'une dilatation de la lame dans un plan horizontal.The inclined lateral rim is adapted to come into contact with a bottom wall of the groove of the blade in which it is engaged, in particular during expansion of the blade in a horizontal plane.

Le sens d'inclinaison du rebord latéral est opposé à celui des griffes.The direction of inclination of the side rim is opposite to that of the claws.

Avantageusement, l'élément de verrouillage comprend une vis, qui comprend une tête de vis, et la tête de vis vient en appui contre l'élément de maintien lorsque le dispositif de fixation est solidarisé au support.Advantageously, the locking element comprises a screw, which comprises a screw head, and the screw head bears against the holding element when the fixing device is secured to the support.

La vis comporte un corps fileté terminé par la tête de vis. A l'extrémité opposée de la tête de vis se trouve une pointe auto-foreuse.The screw has a threaded body terminated by the screw head. At the opposite end of the screw head is a self-drilling point.

La tête de vis exerce donc une poussée sur l'élément de maintien, et préférentiellement de l'insert métallique, dirigée vers l'embase lorsque le dispositif de fixation est solidarisé au support.The screw head therefore exerts a thrust on the retaining element, and preferably on the metal insert, directed towards the base when the fixing device is secured to the support.

Avantageusement, l'orifice de l'embase, le trou du boitier et l'ouverture de l'élément de maintien sont alignés et conformés pour être traversés par l'élément de verrouillage lorsque le dispositif de fixation est solidarisé au support.Advantageously, the orifice of the base, the hole of the housing and the opening of the holding element are aligned and shaped to be traversed by the locking element when the fixing device is secured to the support.

Selon un aspect avantageux de l'invention, le boitier comporte des alvéoles de façon à pouvoir être écrasé sur lui-même selon la direction longitudinale de l'embase.According to an advantageous aspect of the invention, the box comprises cells so as to be able to be crushed on itself in the longitudinal direction of the base.

En cas de dilatation des lames dans un plan horizontal, c'est-à-dire selon la largeur des lames, les bords longitudinaux de deux lames adjacentes se rapprochent l'un de l'autre. Le boitier, et de préférence le premier organe de guidage, se déforment en s'écrasant légèrement de façon à absorber la dilatation des lames, ce qui permet d'éviter que les lames ne vrillent ou s'abiment en cas de dilatation. La déformabilité du boitier et du premier organe de guidage est configurée pour permettre aux lames de venir quasiment en contact de l'élément de verrouillage.In the event of expansion of the slats in a horizontal plane, that is to say along the width of the slats, the longitudinal edges of two adjacent slats approach each other. The housing, and preferably the first guide member, deforms by crushing slightly so as to absorb the expansion of the blades, which makes it possible to prevent the blades from twisting or being damaged in the event of expansion. The deformability of the casing and of the first guide member is configured to allow the blades to almost come into contact with the locking element.

L'invention porte en outre une installation comportant un support, des premier et deuxième lames de terrasse et au moins un dispositif de fixation selon l'invention, dans lequel chacune des première et deuxième lames présente une rainure ménagée le long d'au moins l'un de ses bords longitudinaux, les rainures des première et deuxième lames étant disposées en vis-à-vis de part et d'autre du boitier du dispositif de fixation, les première et deuxième lames étant posées sur l'embase et l'embase du dispositif de fixation étant solidaire du support, tandis que l'élément de maintien du dispositif de fixation est engagé dans les rainures, l'élément de verrouillage étant introduit dans l'élément de maintien, dans le boitier et dans l'embase tout en étant serré de façon exercer un effort sur l'élément de maintien dirigé vers le support en sorte de plaquer les première et deuxième lames contre l'embase, et plaquer l'embase contre le support.The invention further relates to an installation comprising a support, first and second decking boards and at least one fixing device according to the invention, in which each of the first and second boards has a groove formed along at least the one of its longitudinal edges, the grooves of the first and second strips being arranged opposite one another on either side of the housing of the fixing device, the first and second strips being placed on the base and the base of the fixing device being integral with the support, while the holding element of the fixing device is engaged in the grooves, the locking element being introduced into the holding element, into the housing and into the base while being tightened so as to exert a force on the holding element directed towards the support so as to press the first and second blades against the base, and press the base against the support.

Description détailléedetailed description

Sur la figure 1 , on a illustré un mode de réalisation d'un dispositif de fixation 10 pour fixer à un support S une première lame de terrasse 100 et une deuxième lame de terrasse 200. De façon connue, la première lame de terrasse 100 a un bord longitudinal 102 dans lequel est ménagée une rainure 104 qui s'étend selon la direction longitudinale de la première lame de terrasse. La deuxième lame de terrasse 200 a un bord longitudinal 202 dans lequel est ménagée une rainure 204 qui s'étend selon la direction longitudinale de la première lame de terrasse. Les première et deuxième lames de terrasse 100,200 sont parallèles l'une à l'autre selon leurs directions longitudinales et coopèrent chacune avec le dispositif de fixation 10.On the figure 1 , there is illustrated an embodiment of a fixing device 10 for fixing to a support S a first decking board 100 and a second decking board 200 . In known manner, the first decking board 100 has a longitudinal edge 102 in which is made a groove 104 which extends in the longitudinal direction of the first decking board. The second decking board 200 has a longitudinal edge 202 in which is made a groove 204 which extends in the longitudinal direction of the first decking board. The first and second decking boards 100 , 200 are parallel to each other in their longitudinal directions and each cooperates with the fastening device 10 .

Dans cet exemple, le support S est constitué d'un treillis de lambourde 2.In this example, the support S consists of a latticework of joists 2 .

Le dispositif de fixation 10 comporte une embase 12 ayant une face supérieure 14 et une face inférieure 16.The fixing device 10 comprises a base 12 having an upper face 14 and a lower face 16 .

A l'aide des figures 11 à 14 , on comprend que la face supérieure 14 est destinée à porter les lames de terrasse 100, 200, tandis que la face inférieure 16 de l'embase 12 est plaquée contre la lambourde 2.Using the figures 11 to 14 , it is understood that the upper face 14 is intended to carry the decking boards 100 , 200, while the lower face 16 of the base 12 is pressed against the joist 2 .

L'embase 12 comporte par ailleurs un premier organe de guidage 18 et un second organe de guidage 20 qui font saillie perpendiculairement à la face supérieure 14 selon une première direction D1.The base 12 also comprises a first guide member 18 and a second guide member 20 which project perpendicularly to the upper face 14 in a first direction D1 .

Dans cet exemple, l'embase 12 est constituée d'un matériau plastique.In this example, the base 12 is made of a plastic material.

En se référant aux figures 2 à 4 , on constate que l'embase comprend un piètement muni d'échancrures 24 définies entre des patins 26. On comprend à l'aide des figures 11 à 14 que lorsque l'embase 12 est posée sur la lambourde 2, les patins 26 viennent en appui contre la surface supérieure de la lambourde 2. Les échancrures 24 permettent d'assurer une ventilation sous les lames 100, 200, et aussi évacuer l'eau de pluie.By referring to figures 2 to 4 , it can be seen that the base comprises a base provided with indentations 24 defined between pads 26 . We understand with the help of figures 11 to 14 that when the base 12 is placed on the joist 2 , the pads 26 bear against the upper surface of the joist 2 . The indentations 24 make it possible to provide ventilation under the blades 100 , 200 , and also to evacuate rainwater.

Selon un aspect avantageux de l'invention, les premier et second organes de guidage 18, 20 présentent la forme d'ergots creux. Les premier et second organes de guidage 18, 20 comportent à cet effet des évidements 18a et 20a, visibles sur la figure 3 , qui permettent aux premier et second organes de guidage 18, 20 de pouvoir s'écraser radialement, notamment pour absorber une dilatation horizontale des lames.According to an advantageous aspect of the invention, the first and second guide members 18 , 20 have the form of hollow lugs. The first and second guide members 18 , 20 comprise for this purpose recesses 18a and 20a , visible on the picture 3 , which allow the first and second organs guide 18 , 20 to be able to crush radially, in particular to absorb horizontal expansion of the blades.

Par ailleurs, comme on le voit sur les figures 1 et 2 , considérée selon la direction longitudinale DL de l'embase 12, la face supérieure 14 de l'embase 12 comporte deux portions d'embase 12a, 12b qui sont disposées de part et d'autre des premier et deuxième organes de guidage 10, 20, pour recevoir les deux lames de terrasse 100, 200.Moreover, as seen in the figure 1 and 2 , considered along the longitudinal direction DL of the base 12 , the upper face 14 of the base 12 comprises two base portions 12a , 12b which are arranged on either side of the first and second guide members 10 , 20 , to receive the two decking boards 100 , 200 .

Dans cet exemple, chacune des deux portions d'embase 12a, 12b comporte des évidements 12c, 12d qui sont bordés par un bord périphérique 15 de l'embase 12. On comprend que les lames 100, 200 prennent appui sur ce bord périphérique 15.In this example, each of the two base portions 12a , 12b comprises recesses 12c , 12d which are bordered by a peripheral edge 15 of the base 12 . It is understood that the blades 100 , 200 rest on this peripheral edge 15 .

Les évidements 12c, 12d participent à une bonne ventilation sous les lames 100, 200, et à l'évacuation de l'eau de pluie.The recesses 12c , 12d contribute to good ventilation under the blades 100 , 200 , and to the evacuation of rainwater.

On comprend donc que les évidements 12c et 12d, associés aux échancrures 24, assurent une très bonne ventilation sous les lames 100, 200 et facilitent l'évacuation de l'eau de pluie.It is therefore understood that the recesses 12c and 12d , associated with the notches 24 , provide very good ventilation under the blades 100 , 200 and facilitate the evacuation of rainwater.

Par ailleurs, l'embase 12 comporte un orifice 40 qui traverse l'épaisseur de l'embase 12. Comme on le constate sur la figure 2 , l'orifice 40 est disposé entre les premier et second organes de guidage 18, 20. Furthermore, the base 12 includes an orifice 40 which passes through the thickness of the base 12 . As can be seen on the picture 2 , the orifice 40 is disposed between the first and second guide members 18 , 20.

L'orifice 40 est donc traversant et s'étend selon une direction D2 qui est parallèle à la première direction D1. Cette direction D2 est verticale lorsque l'embase est posée sur la lambourde 2. On constate par ailleurs sur la figure 2 que les centres des premier et second organes de guidage 18, 20 et le centre de l'orifice 40 sont alignés selon une direction parallèle à la direction transversale de l'embase 12.The orifice 40 is therefore through and extends in a direction D 2 which is parallel to the first direction D1 . This direction D 2 is vertical when the base is placed on the joist 2 . It is also observed on the figure 2 that the centers of the first and second guide members 18 , 20 and the center of the orifice 40 are aligned in a direction parallel to the transverse direction of the base 12 .

Plus précisément, l'orifice 40 est ménagé dans une partie formant un pont reliant les deux bords longitudinaux 15a, 15b du bord périphérique 15 de l'embase.More specifically, the orifice 40 is formed in a part forming a bridge connecting the two longitudinal edges 15a , 15b of the peripheral edge 15 of the base.

En se référant à nouveau à la figure 1 , on constate que le dispositif de fixation 10 comporte en outre un boîtier 50, dans cet exemple, réalisé en plastique, qui constitue une pièce distincte de l'embase.Referring again to the picture 1 , it is noted that the fixing device 10 further comprises a housing 50 , in this example, made of plastic, which constitutes a separate part of the base.

Le boîtier 50 est illustré plus en détail sur les figures 5 à 8 . Comme illustré en figures 6 et 7 , le boîtier 50 comporte une première cavité 52 pour recevoir le premier organe de guidage 18, et une seconde cavité 54 pour recevoir le second organe de guidage 20 lorsque le boîtier 50 est monté sur l'embase 12.Housing 50 is illustrated in more detail in the figures 5 to 8 . As illustrated in figures 6 and 7 , the housing 50 includes a first cavity 52 for receiving the first guide member 18 , and a second cavity 54 for receiving the second guide member 20 when the housing 50 is mounted on the base 12 .

A l'aide des figures 11 à 14 , on comprend que le boîtier 5 coopère avec les premier et second organes de guidage 18, 20 en sorte que le boîtier 50 est monté coulissant par rapport à l'embase 12 selon la première direction D1. Using the figures 11 to 14 , it is understood that the housing 5 cooperates with the first and second guide members 18 , 20 so that the housing 50 is mounted to slide relative to the base 12 in the first direction D1.

Le boîtier 50 comporte en outre des alvéoles 56 qui, considérées selon la longueur x du boîtier 50, sont disposées entre les première et seconde cavités 52, 54. Les alvéoles 56 permettent au boîtier 50 d'être écrasé sur lui-même selon sa largeur y, notamment lors d'une dilatation horizontale des lames.The casing 50 further comprises cells 56 which, considered along the length x of the casing 50, are arranged between the first and second cavities 52 , 54 . The cells 56 allow the box 50 to be crushed on itself according to its width y , in particular during a horizontal expansion of the blades.

Lorsque le boîtier 50 est monté sur l'embase 12, on comprend que la direction longitudinale Dx du boîtier 50 est parallèle à la direction transversale DT de l'embase 12.When the box 50 is mounted on the base 12 , it is understood that the longitudinal direction Dx of the box 50 is parallel to the transverse direction DT of the base 12 .

Le boîtier 50 comporte par ailleurs un trou 60 qui s'étend selon la hauteur z du boîtier 50 et qui est traversant. Considéré selon la direction longitudinale Dx du boîtier 50, le trou 60 est situé sensiblement au milieu du boîtier 50, entre les première et seconde cavités.The box 50 also includes a hole 60 which extends along the height z of the box 50 and which is through. Considered along the longitudinal direction Dx of the housing 50 , the hole 60 is located substantially in the middle of the housing 50 , between the first and second cavities.

Le boîtier 50 comporte en outre une paroi supérieure 58 dans laquelle débouche l'orifice 60.The casing 50 further comprises an upper wall 58 into which the orifice 60 opens.

Le boîtier 50 comporte en outre une fente 64, visible en figure 7 , qui est située sous la paroi supérieure 62 et qui débouche latéralement de part et d'autre de la largeur y du boîtier 50.The housing 50 further comprises a slot 64 , visible in figure 7 , which is located under the upper wall 62 and which emerges laterally on either side of the width y of the housing 50 .

Cette fente s'étend selon quasiment toute la longueur x du boîtier, et sur toute sa largeur y.This slot extends along almost the entire length x of the housing, and over its entire width y .

Le dispositif de fixation 10, tel qu'illustré en figure 1 , comporte en outre un dispositif de maintien 70 qui est monté au boîtier 50 et, comme illustré aux figures 11 à 14 , est configuré pour être engagé dans les rainures 104, 204 des lames de terrasse 100, 200. On constate sur la figure 1 , que l'élément de maintien 70 fait saillie de part et d'autre de la largeur du boîtier.The fixing device 10 , as illustrated in picture 1 , further comprises a holding device 70 which is mounted to the housing 50 and, as illustrated in figures 11 to 14 , is configured to be engaged in the grooves 104 , 204 of the decking boards 100 , 200 . We see on the picture 1 , that the holding element 70 protrudes on either side of the width of the housing.

L'élément de maintien 70 est un insert 72, métallique dans cet exemple, qui solidaire du boîtier 50. Plus précisément, l'insert 72 présente la forme d'une plaquette 74 qui est disposée dans la fente 64 du boîtier 50.The holding element 70 is an insert 72 , metallic in this example, which is integral with the casing 50 . More specifically, the insert 72 has the shape of a plate 74 which is placed in the slot 64 of the housing 50 .

La plaquette 74 comporte donc une première portion 74a en saillie par rapport au boîtier 50 et formant une première ailette. La plaquette 74 comporte en outre une seconde portion 74b en saillie par rapport au boîtier 50 et formant une seconde ailette opposée à la première ailette. L'insert 72 est illustré plus en détail aux figures 9 et 10 . La plaquette fait saillie de part et d'autre des bords longitudinaux du boitier.The wafer 74 therefore comprises a first portion 74a projecting relative to the housing 50 and forming a first fin. Plate 74 further includes a second portion 74b projecting relative to housing 50 and forming a second fin opposite to the first fin. Insert 72 is illustrated in greater detail in figures 9 and 10 . The wafer protrudes on either side of the longitudinal edges of the case.

La plaquette 74 comporte une ouverture 76 qui est traversante selon l'épaisseur de la plaquette 74.The wafer 74 has an opening 76 which passes through the thickness of the wafer 74 .

Dans cet exemple, le boîtier 50 est en plastique et est surmoulée avec la plaquette 74 métallique. Le trou 60 du boîtier 50 et l'ouverture 76 de la plaquette 74 sont coaxiaux. Dans cet exemple, le trou 60 du boîtier 50 est en retrait radialement par rapport à l'ouverture 76 de la plaquette 74. Pour ce faire, le diamètre du trou 60 du boîtier 50 est plus grand que le diamètre de l'ouverture 76.In this example, the housing 50 is made of plastic and is overmolded with the metal plate 74 . The hole 60 of the housing 50 and the opening 76 of the plate 74 are coaxial. In this example, the hole 60 of the housing 50 is set back radially with respect to the opening 76 of the plate 74 . To do this, the diameter of the hole 60 of the housing 50 is larger than the diameter of the opening 76 .

Comme illustré en figure 9 , la plaquette 74 est munie de griffes 75 qui s'étendent depuis un bord latéral 74c de la plaquette. Ces griffes sont configurées pour venir en appui dans une paroi de la rainure de la lame.As illustrated in figure 9 , the wafer 74 is provided with claws 75 which extend from a side edge 74c of the wafer. These claws are configured to bear against a wall of the groove of the blade.

Précisément, les griffes 75 sont configurées pour venir en appui dans une paroi inférieure 102a de la rainure 104 de la première lame 100. La plaquette 74 présente en outre un rebord latéral 74d opposé au bord latéral 74c, ce rebord latéral 74d ayant un pli ou bourrelet 77. Comme on le comprend à l'aide des figures 11 à 14, le bourrelet 77 est configuré pour venir en appui contre une paroi inférieure 204a de la rainure 204 de la deuxième lame 200.Specifically, the claws 75 are configured to bear against a lower wall 102a of the groove 104 of the first blade 100 . The wafer 74 also has a side edge 74d opposite the side edge 74c , this side edge 74d having a fold or bead 77 . As we understand from the figures 11 to 14 , the bead 77 is configured to bear against a lower wall 204a of the groove 204 of the second strip 200 .

Le dispositif de fixation 10 comporte en outre un élément de verrouillage 80 qui est configuré pour solidariser le dispositif de fixation et la lames au support. Dans cet exemple, l'élément de verrouillage 80 est une vis qui comporte une tige filetée 82 ayant une première extrémité 82a munie d'une tête 84, et une seconde extrémité longitudinale 82b munie d'une pointe auto-perforante 86.The fixing device 10 further comprises a locking element 80 which is configured to secure the fixing device and the blades to the support. In this example, the locking element 80 is a screw which comprises a threaded rod 82 having a first end 82 a provided with a head 84 , and a second longitudinal end 82 b provided with a self-perforating point 86 .

On comprend, à l'aide des figures 11 à 14 , que l'orifice 40 est conformé pour recevoir l'élément de verrouillage 80 lorsque le dispositif de fixation 10 est solidarisé au support. Le trou 60 est quant à lui conformé pour recevoir l'élément de verrouillage 80 lorsque le dispositif de fixation 10 est solidarisé au support. Enfin, l'ouverture 76 est conformée pour recevoir l'élément de verrouillage 80 lorsque le dispositif de fixation est solidarisé au support. Dans cet exemple, la tête de vis 84 de l'élément de verrouillage vient en appui contre l'élément de maintien 70 lorsque le dispositif de fixation est solidarisé au support. On comprend également que l'orifice 40 de l'embase 12, le trou 60 du boîtier 50 et l'ouverture 76 de l'élément de maintien sont alignés et conformés pour être traversés par l'élément de verrouillage 80 lorsque le dispositif de fixation est solidarisé au support.We understand, with the help of figures 11 to 14 , that the orifice 40 is shaped to receive the locking element 80 when the fixing device 10 is secured to the support. The hole 60 is itself shaped to receive the locking element 80 when the fixing device 10 is secured to the support. Finally, the opening 76 is shaped to receive the locking element 80 when the fixing device is secured to the support. In this example, the screw head 84 of the locking element bears against the holding element 70 when the fastening device is secured to the support. It is also understood that the orifice 40 of the base 12 , the hole 60 of the housing 50 and the opening 76 of the holding element are aligned and shaped to be crossed by the locking element 80 when the fixing device is attached to the support.

Dans la mesure où le trou du boîtier est en retrait radial par rapport à l'ouverture 76 de la plaquette 74, on comprend que la tête 84 de la vis 82 vient directement en appui contre l'insert métallique 72 lorsque le dispositif de fixation est solidarisé au support.Insofar as the hole in the housing is set back radially with respect to the opening 76 of the plate 74 , it is understood that the head 84 of the screw 82 bears directly against the metal insert 72 when the fixing device is attached to the support.

Sur les figures 11 et 12 , on a illustré un premier mode de réalisation d'une installation 500 conforme à l'invention. Cette installation 500 comporte un support constitué d'une lambourde 2, des première et deuxième lames de terrasse 100, 200 ayant une épaisseur e1. Comme expliqué ci-dessus, la rainure 104de la première lame 100 comporte une paroi inférieure 104a, tandis que la rainure 204 comporte une paroi inférieure 204a. Les parois inférieures 104a, 204a sont parallèles à la face supérieure de l'embase 12.On the figures 11 and 12 , a first embodiment of an installation 500 according to the invention has been illustrated. This installation 500 comprises a support consisting of a sleeper 2 , first and second decking boards 100 , 200 having a thickness e 1. As explained above, the groove 104 of the first board 100 comprises a lower wall 104 a, while the groove 204 has a bottom wall 204a . The lower walls 104 a , 204 a are parallel to the upper face of the base 12 .

L'installation 500 comporte en outre un dispositif de fixation 10 selon l'invention, à savoir celui de la figure 1 . Les rainures 104, 204 des première et deuxième lames 100,200 sont disposées en vis-à-vis l'une de l'autre de part et d'autre du boîtier 50 du dispositif de fixation 10. L'embase 12 du dispositif de fixation 10 est posée sur le support 2, tandis que l'élément de maintien 70 du dispositif de fixation 10 est engagé dans les rainures 102, 202. L'élément de verrouillage 80 est engagé successivement dans l'élément de maintien 70, dans le boîtier 50 en sorte de plaquer les première et deuxième lames 100, 200 et l'embase 12 contre le support 2.The installation 500 further comprises a fixing device 10 according to the invention, namely that of the figure 1 . The grooves 104 , 204 of the first and second blades 100 , 200 are arranged opposite one another on either side of the housing 50 of the fixing device 10 . The base 12 of the fixing device 10 is placed on the support 2 , while the holding element 70 of the fixing device 10 is engaged in the grooves 102 , 202 . The locking element 80 is engaged successively in the holding element 70 , in the housing 50 so as to press the first and second blades 100 , 200 and the base 12 against the support 2 .

Sur la figure 15 , on a illustré le comportement du dispositif de fixation 10 selon l'invention dans une situation dans laquelle les lames 100 et 200 se dilatent, par exemple en raison d'une augmentation de l'humidité de l'air qui fait gonfler les lames.On the figure 15 , the behavior of the fastening device 10 according to the invention has been illustrated in a situation in which the blades 100 and 200 expand, for example due to an increase in the humidity of the air which causes the blades to swell.

Tel qu'illustré en figures 12 et 15 , cette dilatation a pour effet que les bords longitudinaux 102,202 des première et deuxième lames 100,200 se rapprochent l'un de l'autre. En pratique, ce rapprochement est de l'ordre de quelques millimètres.As illustrated in figure 12 and 15 , this expansion has the effect that the longitudinal edges 102 , 202 of the first and second blades 100,200 approach each other. In practice, this rapprochement is of the order of a few millimeters.

Comme exposé ci-dessus, le boitier 50 et les ergots 18,20 de l'embase 12 sont déformables. Plus précisément, ils peuvent être légèrement écrasés sur eux-mêmes dans un plan horizontal.As explained above, the box 50 and the lugs 18 , 20 of the base 12 are deformable. More precisely, they can be slightly crushed on themselves in a horizontal plane.

En cas de dilatation très importante des lames, les bords longitudinaux des lames viennent pincer le boitier. Grâce à la déformabilité du boitier, et de préférence des ergots qui sont alors engagés dans le boitier, le boitier et les ergots se déforment légèrement en s'écrasant sous l'action du pincement. Ceci a pour effet de reprendre, sur quelques millimètres, l'expansion horizontale des lames et d'éviter ainsi que les lames se tordent ou se désengagent du dispositif de fixation. Lorsque l'humidité diminue, les lames se contractent et s'éloignent légèrement l'une de l'autre. Le boitier et les ergots reprennent alors leur forme initiale.In the event of very significant expansion of the slats, the longitudinal edges of the slats pinch the box. Thanks to the deformability of the casing, and preferably of the lugs which are then engaged in the casing, the casing and the lugs deform slightly by crushing under the action of pinching. This has the effect of resuming, over a few millimetres, the horizontal expansion of the blades and thus prevent the blades from twisting or disengaging from the fastening device. When the humidity drops, the blades contract and move slightly apart. The case and the lugs then return to their initial shape.

Les terrasses réalisées à l'aide de dispositifs de fixation selon l'invention présentent donc une meilleure résilience et durabilité que celles réalisées avec des clips de fixation traditionnels.The terraces made using fastening devices according to the invention therefore have better resilience and durability than those made with traditional fastening clips.
