Ladite au moins une chambre étanche 31 est destinée à être remplie avec un fluide, par exemple un liquide (eau par exemple) ou un gaz (air par exemple).Said at least one sealed chamber 31 is intended to be filled with a fluid, for example a liquid (water for example) or a gas (air for example).

Ce matelas intercalaire 3 comporte pour cela une valve de remplissage (non représentée) en communication fluidique entre la chambre étanche 31 et l'extérieur.This interlayer mattress 3 comprises for this purpose a filling valve (not shown) in fluid communication between the sealed chamber 31 and the outside.

Le matelas intercalaire 3 comporte avantageusement des peaux 3a, 3b définissant ladite au moins une chambre étanche 31 :

  • une peau inférieure 3a, ménagée du côté de la couche support 2, et
  • une peau supérieure 3b, ménagée du côté de la couche supérieure 4.
The intermediate mattress 3 advantageously comprises skins 3a, 3b defining said at least one sealed chamber 31:
  • a lower skin 3a, provided on the side of the support layer 2, and
  • an upper skin 3b, provided on the side of the upper layer 4.

Une fois ladite au moins une chambre étanche 31 remplie, le matelas intercalaire 3 présente avantageusement une forme générale parallélépipédique ou une forme bombée convexe ou une forme de calotte sphérique.Once said at least one sealed chamber 31 has been filled, the intermediate mattress 3 advantageously has a general parallelepiped shape or a convex rounded shape or a spherical cap shape.

Une fois ladite au moins une chambre étanche 31 remplie, ladite au moins une chambre étanche 31 remplie présente une épaisseur allant de 10 à 100 mm, de préférence de 30 à 100 mm.Once said at least one sealed chamber 31 is filled, said at least one filled sealed chamber 31 has a thickness ranging from 10 to 100 mm, preferably from 30 to 100 mm.

De manière générale et tel que représenté sur les figures 2 et 3, le matelas intercalaire 3 comporte une bande hermétique 32 délimitant ladite au moins une chambre étanche 31.In general and as represented on the figures 2 and 3 , the interlayer mattress 3 comprises a hermetic strip 32 delimiting said at least one sealed chamber 31.

La bande hermétique 32 comporte au moins un tronçon 321 fermé hermétiquement par une soudure (représenté sur les figures 2 et 3) et/ou par une paire de profilés qui pincent ce tronçon (non représentés).The hermetic strip 32 comprises at least one section 321 hermetically closed by a weld (shown on the figures 2 and 3 ) and/or by a pair of profiles which pinch this section (not shown).

De préférence, les profilés comportent des formes complémentaires et sont reliés par des organes de liaison qui traversent le tronçon 321.Preferably, the profiles have complementary shapes and are connected by connecting members which pass through section 321.

De préférence, la bande hermétique 32 présente une forme de cadre qui comporte plusieurs tronçons 321 :

  • deux tronçons longitudinaux, avantageusement fermés hermétiquement par une soudure, et
  • deux tronçons transversaux, avantageusement fermés hermétiquement par une soudure ou une paire de profilés.
Preferably, the hermetic strip 32 has the shape of a frame which comprises several sections 321:
  • two longitudinal sections, advantageously hermetically closed by welding, and
  • two transverse sections, advantageously hermetically closed by a weld or a pair of profiles.

La mise en oeuvre de moyens de fermeture par « profilés » permet un ajustement à façon de la longueur du matelas intercalaire 3 et de sa chambre étanche 31.The implementation of closing means using “profiles” allows custom adjustment of the length of the interlayer mattress 3 and its waterproof chamber 31.

Encore de manière générale, le matelas intercalaire 3 comporte une bande périphérique 33 qui est solidarisée avec la couche support 2, avantageusement par l'intermédiaire d'un profilé 6 rapporté par des organes traversants 7.Still generally speaking, the interlayer mattress 3 comprises a peripheral strip 33 which is secured to the support layer 2, advantageously via a profile 6 attached by through members 7.

La bande périphérique 33 est ainsi pincée entre le profilé 6 et une couche sous-jacente.The peripheral strip 33 is thus pinched between the profile 6 and an underlying layer.

Les organes traversants 7 traversent le profilé 6 et la bande périphérique 33, de sorte à s'ancrer avantageusement dans la couche support 2.The through members 7 pass through the profile 6 and the peripheral strip 33, so as to be anchored advantageously in the support layer 2.

La bande périphérique 33 présente avantageusement une largeur allant de 100 à 200 mm.The peripheral strip 33 advantageously has a width ranging from 100 to 200 mm.

En l'espèce, la bande hermétique 32 et la bande périphérique 33 sont confondus ou forme une même structure.In this case, the hermetic strip 32 and the peripheral strip 33 are combined or form the same structure.

En d'autres termes, la bande périphérique 33 forme ici la bande hermétique 32 délimitant la chambre étanche 31.In other words, the peripheral strip 33 here forms the hermetic strip 32 delimiting the sealed chamber 31.

Encore de manière générale, la surface du matelas intercalaire 3 est avantageusement inférieure par rapport à la surface de la couche support 2 et par rapport à la surface de la couche supérieure 4.Still generally speaking, the surface of the interlayer mattress 3 is advantageously less compared to the surface of the support layer 2 and compared to the surface of the upper layer 4.

Cette particularité permet de conserver un espace périphérique 1a, ou trottoir, qui est plus ferme autour du matelas intercalaire 3 (figure 1), utile notamment sur le plan de la sécurité en cas de chute de l'utilisateur (avantageusement hauteur de chute critique pour les jeux d'enfants).This particularity makes it possible to maintain a peripheral space 1a, or sidewalk, which is firmer around the interlayer mattress 3 ( figure 1 ), useful in particular in terms of safety in the event of the user falling (advantageously critical fall height for children's games).

De préférence, cet espace périphérique 1a présente par exemple une largeur allant de 1 à 1,5 m.Preferably, this peripheral space 1a has for example a width ranging from 1 to 1.5 m.

Par « gazons synthétiques » (dites encore « pelouses synthétiques » ou « pelouses artificielles » ou encore « gazons artificiels »), on entend avantageusement une surface imitant la pelouse naturelle.By “synthetic lawns” (also called “synthetic lawns” or “artificial lawns” or even “artificial lawns”), we advantageously mean a surface imitating natural lawn.

Un tel gazon synthétique comprend avantageusement des brins de plastique (imitant le gazon) qui sont rapportés sur un support (tissé ou non-tissé) muni de trous de drainage.Such synthetic turf advantageously comprises strands of plastic (imitating grass) which are attached to a support (woven or non-woven) provided with drainage holes.

La couche supérieure 4 peut comporter deux aspects différents :

  • un premier aspect dans une zone sus-jacente du matelas intercalaire 3, et
  • un second aspect dans une zone entourant ledit matelas intercalaire 3.
The upper layer 4 can have two different aspects:
  • a first aspect in an overlying zone of the interlayer mattress 3, and
  • a second aspect in an area surrounding said interlayer mattress 3.

Encore de manière générale, la couche supérieure 4 est avantageusement solidarisée avec la couche support 2, de préférence par l'intermédiaire de profilés 41 qui sont rapportés par d'organes traversants 42.Still generally, the upper layer 4 is advantageously secured to the support layer 2, preferably via profiles 41 which are attached by through members 42.

La couche supérieure 4 est ainsi pincée entre les profilés 41 et une couche sous-jacente.The upper layer 4 is thus pinched between the profiles 41 and an underlying layer.

Les organes traversants 42 traversent avantageusement les profilés 41 et la couche supérieure 4, de sorte à s'ancrer dans la couche support 2.The through members 42 advantageously pass through the profiles 41 and the upper layer 4, so as to anchor themselves in the support layer 2.

De manière générale, le contour périphérique de cette couche supérieure 4 correspond avantageusement au contour périphérique de la couche support 2.Generally speaking, the peripheral contour of this upper layer 4 advantageously corresponds to the peripheral contour of the support layer 2.
