La presente invenzione b relativa ad una superficie sportiva di gioco con un manto erboso in fibre sintetiche intasata con materiali di origine naturale. The present invention relates to a sports playing surface with a turf made of synthetic fibers clogged with materials of natural origin.

Sono noti manti erbosi in fibre sintetiche utilizzati come pavimentazioni per campi sportivi, ad esempio, per campi da golf, tennis, hokey o calcio. Synthetic fiber turf grasses used as flooring for sports fields, for example, for golf, tennis, hockey or football fields are known.

Tali manti sono normalmente formati da reticoli di fibre sintetiche in materiale termoplastico, ad esempio in polipropilene, polietilene o poliestere. Le fibre sono fissate (in inglese "tufied") ad un supporto primario, ad esempio realizzato in un tessuto di polipropilene, eventualmente accoppiato a geotessili o a reti di rinfom, il quale viene poi spalmato sul rovescio con lattice di gomma sintetico, poliuretano PVC o altro per ancorare definitivamente le fibre al supporto primario, in modo che le fibre stesse assumano complessivamente una forma a V e una lunghezza finale opportuna d These mantles are normally formed by networks of synthetic fibers in thermoplastic material, for example in polypropylene, polyethylene or polyester. The fibers are fixed (in English "tufied") to a primary support, for example made of a polypropylene fabric, possibly coupled to geotextiles or reinforcing nets, which is then spread on the reverse side with synthetic rubber latex, polyurethane PVC or other to definitively anchor the fibers to the primary support, so that the fibers themselves take on a V-shape overall and a suitable final length d

superficie in erba naturale. Le fibre sono normalmente mantenute in posizione "eretta" tramite un materiale di intasamento consistente in uno strato di sabbia che impedisce il piegamento totale della fibra anche durante l'uso del manto erboso stesso. Al di sopra c'è uno strato di materiale tennoplastico e10 vulcanizzato in granuli comprendente ad esempio polietilene stabilizzato ai raggi ultravioletti derivato da un operazione di riciclaggio o non, ma pub ad esempio comprendere polipropilene, e può essere addittivato con un materiale elastomerico ad esempio EPDM o SBR. Detti granuli sono atti a conferire maggiore elasticità al manto erboso nel loro complesso e quindi a favorire un rimbalzo migliore delle palle sulla superficie di gioco e ad evitare eventuali danni agli utilizzatori sulla superficie dura costituita dallo strato compatto in sabbia natural grass surface. The fibers are normally kept in an "upright" position by means of a clogging material consisting of a layer of sand which prevents the total bending of the fiber even during the use of the turf itself. Above there is a layer of tennoplastic material vulcanized in granules comprising for example polyethylene stabilized to ultraviolet rays derived from a recycling operation or not, but can for example comprise polypropylene, and can be added with an elastomeric material such as EPDM or SBR. Said granules are able to give greater elasticity to the turf as a whole and therefore to favor a better rebound of the balls on the playing surface and to avoid any damage to users on the hard surface constituted by the compact layer of sand.

I1 materiale d'intasamento dell'erba sintetica non deve subire alcun tipo di variazione a causa degli agenti atmosferici owero non deve essere igroscopico quindi non gelivo anche senza l'apporto di additivi tipo sale, altamente inquinanti. The clogging material of the synthetic grass must not undergo any type of variation due to atmospheric agents or it must not be hygroscopic therefore it does not freeze even without the addition of highly polluting salt additives.

Inoltre nel momento in cui si rende necessaria la sostituzione del manto erboso b necessano separare la sabbia, il materiale plastico e le fibre sintetiche. L'operazione di separazione risulta però costosa e complessa in quanto il materiale plastico non è più riutilizzabili ed ha un peso specifico elevato, pertanto risulta una operazione antieconomica e svantaggiosa. Furthermore, when it is necessary to replace the turf b, it is necessary to separate the sand, the plastic material and the synthetic fibers. However, the separation operation is expensive and complex since the plastic material is no longer reusable and has a high specific weight, therefore it is an uneconomic and disadvantageous operation.

Scopo della presente invenzione b quello di fornire una superficie che consenta di risolvere in maniera semplice ed economica i problemi sopra esposti e che, in particolare, al momento dello smaltimento non presentino problemi ambientali. The object of the present invention is to provide a surface which allows the above problems to be solved in a simple and economical manner and which, in particular, do not present environmental problems at the time of disposal.

Pag.n...<3>....... Page n ... <3> .......

Secondo la presente invenzione viene fornito un manto erboso comprendente un supporto, fibre sintetiche fissate a detto supporto ed un materiale di intasamento atto a mantenere dette fibre in posizione prestabilita, caratterizzato dal fatto che detto materiale di<intasamento è totalmente naturale, non igroscopico quindi non gelivo>. According to the present invention, a turf is provided comprising a support, synthetic fibers fixed to said support and a blocking material suitable for keeping said fibers in a predetermined position, characterized in that said blocking material is totally natural, non-hygroscopic and therefore not freezing>.

L'invenzione vmh ora descritta con riferimento anche al disegno annesso che illustra un esempio di attuazione non limitativo al manto erboso in fibre ottenuto secondo i dettami della presente invenzione. The invention now described with reference also to the attached drawing which illustrates a non-limiting embodiment of the fiber turf obtained according to the dictates of the present invention.

Nella figura viene designato nel suo complesso con 1) un manto erboso comprendente una pluralità di fibra 2) sintetiche fissate ad un supporto 3) primario. Le fibre hanno lunghezza opportuna da simulare uno strato di erba naturale, ad esempio di 5-70 mm, e sono mantenute in una direzione sostanzialmente eretta, tramite uno strato di sabbia, materiale di intasamento 5), per evitare che durante l'uso si pieghino e che quindi rimangano schiacciate parallelamente al supporto 3) stesso. Le fibre 2 hanno pertanto una configurazione sostanziamente a V perpendicolare al supporto 3) stesso. In the figure 1) a turf comprising a plurality of synthetic fibers 2) fixed to a primary support 3) is designated as a whole. The fibers have a suitable length to simulate a layer of natural grass, for example 5-70 mm, and are kept in a substantially upright direction, by means of a layer of sand, a clogging material 5), to avoid that during use bend and therefore remain flattened parallel to the support 3) itself. The fibers 2 therefore have a substantially V-shaped configuration perpendicular to the support 3) itself.

Le fibre 2 sintetiche sono ad esempio di polietilene, di polipropilene o di poliamide. The synthetic fibers 2 are for example of polyethylene, polypropylene or polyamide.

I1 materiale d'intasamento 5) e 6), è disposto in forma di strato ed b costituito prevalentemente dallo strato 6) dato granuli di materiale organico trattato con materiale poliuretanico, di dimensioni preferibilmente comprese tra 0,l e 5mm. The clogging material 5) and 6) is arranged in the form of a layer and b consists mainly of the layer 6) given granules of organic material treated with polyurethane material, preferably of dimensions between 0.1 and 5mm.

Le percentuali in volume dello strato 6) sono comprese tra il 20% e 1'80% rispetto allo strato 5). The volume percentages of the layer 6) are between 20% and 80% with respect to the layer 5).

<Pahl o IVTA57 O 24200011>I granuli di materiale organico, nella fattispecie sughero, vengono sottoposti ad un intervento di impermeabilizzazione e saturazione dei pori con materiale impermeabilizzante. In tal modo si ottiene un una granulo imputrescibile e rinfoizato all'usura, senza perdere l'elasticità originale del prodotto base, atto a favorire I'elasticità alla superficie da gioco ed, in particolare, a favorire il rimbalzo della palla da gioco ed ad evitare danni fisici degli utilizzatori della superficie di gioco. <Pahl or IVTA57 O 24200011> The granules of organic material, in this case cork, are subjected to a waterproofing and saturation of the pores with waterproofing material. In this way a rot-proof and wear-resistant granule is obtained, without losing the original elasticity of the base product, designed to favor the elasticity of the playing surface and, in particular, to favor the bounce of the game ball and to avoid physical harm to the users of the playing surface.

In particolare, il manto erboso secondo la presente invenzione consente di sostituire il materiale di intasamento di tipo plastici antiecologici con un materiale naturale disponibile a basso costo, ignifugo, non igroscopico quindi non gelivoed imputrescibile. In particular, the turf according to the present invention allows the infill material of the anti-ecological plastic type to be replaced with a natural material available at low cost, fire-retardant, non-hygroscopic and therefore non-gelivorous and rot-proof.

Infine l'utilizzo del granulo naturale nobilitato, nella fattispecie il sughero, 6) come materiale d'intasamento secondo la presente invenzione permette una separazione facile dell'intero manto erboso 1). Finally, the use of the natural ennobled granule, in this case the cork, 6) as a clogging material according to the present invention allows an easy separation of the entire turf 1).

Risulta infine chiaro che al manto erboso 1) realizzato secondo la presente invenzione possono essere apportate modifiche e varianti che non escono dall'ambito di tutela della presente invenzione. Finally, it is clear that modifications and variations may be made to the turf 1) made according to the present invention which do not depart from the scope of protection of the present invention.

In particolare possono essere variati le percentuali e la granulometria dei materiali di intasamento naturale trattato con intervento di impermeabilizzazione e saturazione dei pori con materiale impermeabilizzante, ed i materiali stessi utilizzati come mezzi di intasamento. In particular, the percentages and granulometry of the natural clogging materials treated with waterproofing and saturation of the pores with waterproofing material, and the materials themselves used as clogging means can be varied.
