Description

DESCRIZIONE del modello industriale d’utilità dal titolo: DESCRIPTION of the utility industrial model entitled:

“SPAZZOLA PER IL TRATTAMENTO SUPERFICIALE DI MATERIALI’ "BRUSH FOR THE SURFACE TREATMENT OF MATERIALS '

Il presente trovato riguarda una spazzola per il trattamento superficiale di materiali, ed iu particolare una spazzola utilizzabile in combinazione con le levigatrici per marmi e pietre allo scopo di conferire a questi ultimi un aspetto antichizzato. The present invention relates to a brush for the surface treatment of materials, and in particular to a brush that can be used in combination with sanders for marble and stone in order to give the latter an antiqued appearance.

Sono note macchine per il trattamento superficiale di materiali, iu particolare di marmi e pietre, le quali comprendono alcune spazzole provviste di setole abrasive utilizzabili per conferire ad essi un aspetto antichizzato. Queste macchine note presentano l inconveniente di essere relativamente costose sia nell’acquisto sia nella manutenzione, dato che le spazzole si usurano in maniera non uniforme, per cui risulta necessario sostituirle frequentemente. Machines are known for the surface treatment of materials, particularly marble and stone, which comprise some brushes provided with abrasive bristles which can be used to give them an antiqued appearance. These known machines have the drawback of being relatively expensive both in purchase and maintenance, given that the brushes wear unevenly, so it is necessary to replace them frequently.

Scopo del presente trovato è pertanto quello di fornire una macchina per conferire un aspetto antichizzato alle superimi dei materiali da trattare, la quale sia esente da tali inconvenienti. Detto scopo viene conseguito con ima spazzola le cui caratteristiche principali sono specificate nella prima rivendicazione ed altre caratteristiche sono specificate nelle rivendicazioni successive. The object of the present invention is therefore to provide a machine for giving an antiqued appearance to the surfaces of the materials to be treated, which is free from such drawbacks. Said object is achieved with a brush whose main characteristics are specified in the first claim and other characteristics are specified in the subsequent claims.

Grazie alla particolare forma del supporto delle setole, la spazzola secondo il presente trovato può essere infatti montata nelle levigatrici che comprendono alcuni dischi rotanti, ciascuno dei quali è provvisto di una pluralità di sedi nelle quali vengono generalmente montati i blocchetti abrasivi intercambiabili che realizzano la levigatura. Con questo accorgimento diventa quindi superfluo acquistare una macchina apposita dedicata esclusivamente al conferimento di un aspetto antichizzato, dato che risulta possibile impiegare per questo scopo tali levigatrici, generalmente disponibili in ogni officina che esegue il trattamento superficiale di materiali. Thanks to the particular shape of the bristle support, the brush according to the present invention can in fact be mounted in the sanders which include some rotating discs, each of which is provided with a plurality of seats in which the interchangeable abrasive blocks which perform the polishing are generally mounted. . With this expedient it therefore becomes superfluous to purchase a special machine dedicated exclusively to conferring an antiqued appearance, since it is possible to use these sanding machines for this purpose, generally available in any workshop that performs the surface treatment of materials.

Un altro vantaggio della spazzola secondo il presente trovato è costituito dal minore costo di manutenzione in caso di usura non uniforme, in quanto è sufficiente sostituire solo le spazzole maggiormente usurate, e non tutto l’insieme delle stesse, come nelle macchine note. Another advantage of the brush according to the present invention is the lower maintenance cost in the event of non-uniform wear, as it is sufficient to replace only the most worn brushes, and not all of the same, as in known machines.

Secondo un particolare aspetto del trovato, i fasci di setole abrasive sono disposti secondo un orientamento sostanzialmente radiale rispetto al centro di rotazione dei dischi rotanti, evitando cosi il rischio di rigare i materiali da trattare. According to a particular aspect of the invention, the bundles of abrasive bristles are arranged in a substantially radial orientation with respect to the center of rotation of the rotating discs, thus avoiding the risk of scratching the materials to be treated.

Infine, la particolare forma delle setole abrasive ed il tipo di materiale utilizzato per la loro fabbricazione risultano essere particolarmente idonei all’uso della spazzola secondo il presente trovato per conferire un aspetto antichizzato alla superficie dei materiali da trattare. Finally, the particular shape of the abrasive bristles and the type of material used for their manufacture are particularly suitable for the use of the brush according to the present invention to give an antiqued appearance to the surface of the materials to be treated.

Ulteriori vantaggi e caratteristiche della spazzola secondo il presente trovato risulteranno evidenti agli esperti del ramo dalla seguente dettagliata descrizione di una sua forala realizzativa con riferimento agli annessi disegni in cui: Further advantages and characteristics of the brush according to the present invention will become evident to those skilled in the art from the following detailed description of an embodiment thereof with reference to the attached drawings in which:

- la figura 1 mostra una vista dall’alto di tale forma realizzativa; e - Figure 1 shows a top view of this embodiment; And

la figura 2 mostra una vista frontale della forma realizzativa di figura 1. figure 2 shows a front view of the embodiment of figure 1.

Facendo riferimento a tali figure, si vede che la spazzola secondo la presente forma realizzativa del trovato comprende un supporto 1 di materiale plastico, il quale presenta sostanzialmente una forma di prismoide avente le basi e due superfici laterali contrapposte di forma trapezoidale. Sulla base superiore del supporto 1 è ricavata una pluralità di scanalature parallele, hi particolare quattro scanalature, in ciascuna delle quali è inserita ed incollata, ad esempio mediante una colla epossidica a due componenti, un’estremità di un fascio di setole abrasive 2 a sezione ellittica, preferibilmente realizzate nel materiale denominato Tynex<® >della società DuPont<®>. La grana delle setole abrasive 2 può essere scelta liberamente in funzione dell’effetto che si desidera ottenere, tuttavia si è osservato che si conferisce un gradevole aspetto antichizzato alla maggior parte dei materiali utilizzando setole abrasive aveuti una grana il cui indice è compreso tra 46 e 320. Le scanalature nelle quali sono inseriti i fasci di setole 2 sono preferibilmente disposte parallelamente all’altezza delle basi del supporto l in modo tale che quando la spazzola secondo il presente trovato viene montata su un disco rotante di una levigatrice, tali scanalature risultano disposte secondo un orientamento sostanzialmente radiale rispetto al centro di rotazione del disco. With reference to these figures, it can be seen that the brush according to the present embodiment of the invention comprises a support 1 of plastic material, which substantially has a prismid shape having the bases and two opposite side surfaces of trapezoidal shape. On the upper base of the support 1 there is obtained a plurality of parallel grooves, in particular four grooves, in each of which an end of a bundle of abrasive bristles 2 in section is inserted and glued, for example by means of a two-component epoxy glue. elliptical, preferably made of the material called Tynex <®> from DuPont <®>. The grain of the abrasive bristles 2 can be freely chosen according to the desired effect, however it has been observed that a pleasant antiqued appearance is given to most materials by using abrasive bristles whose grain index is between 46 and 320. The grooves in which the bundles of bristles 2 are inserted are preferably arranged parallel to the height of the bases of the support l so that when the brush according to the present invention is mounted on a rotating disk of a sanding machine, these grooves are arranged according to a substantially radial orientation with respect to the center of rotation of the disc.

Ulteriori varianti e/o aggiunte possono essere apportate dagli esperti del ramo alla forma realizzativa qui descritta ed illustrata restando nell’ambito del trovato stesso. Further variations and / or additions can be made by those skilled in the art to the embodiment described and illustrated here while remaining within the scope of the invention itself.
