DESCRIZIONE DESCRIPTION

“VOMERE PERFEZIONATO PER SPALARE NEVE†⠀ œPOMERE PERFECTED FOR SHOVELING SNOWâ €

La presente invenzione à ̈ relativa a un vomere perfezionato preferibilmente per spalare neve ad alta velocità. The present invention relates to an improved share preferably for shoveling snow at high speed.

Un vomere viene normalmente realizzato interamente in acciaio e presenta un primo e un secondo volvente mobili fra loro intorno ad un asse verticale. Le lame possono essere configurate in posizioni discrete tramite l’azione di cilindri idraulici. A ploughshare is normally made entirely of steel and has a first and a second rolling element movable between them around a vertical axis. The blades can be configured in discrete positions through the action of hydraulic cylinders.

Un vomere in acciaio à ̈ normalmente impiegato quando su una strada la neve forma una coltre di spessore considerevole, come ad esempio in valichi di alta montagna. La struttura particolarmente robusta e resistente à ̈ progettata per spostare quantitativi elevati di neve ad una velocità ridotta, i.e. 5-10 km/h. A steel ploughshare is normally used when the snow forms a layer of considerable thickness on a road, such as in high mountain passes. The particularly robust and resistant structure is designed to move large quantities of snow at a reduced speed, i.e. 5-10 km / h.

Lo scopo della presente invenzione à ̈ di realizzare un vomere più leggero e adatto a un utilizzo versatile a velocità più elevate. The object of the present invention is to produce a lighter share suitable for versatile use at higher speeds.

Lo scopo della presente invenzione viene raggiunto tramite un vomere secondo la rivendicazione 1. The object of the present invention is achieved by means of a share according to claim 1.

Per una migliore comprensione della presente invenzione viene ora descritta una forma di realizzazione preferita, a puro titolo di esempio non limitativo, con riferimento ai disegni allegati in cu: For a better understanding of the present invention, a preferred embodiment is now described, purely by way of non-limiting example, with reference to the accompanying drawings in which:

- le figure 1a, b, c sono rispettive viste frontali di un vomere secondo la presente invenzione in differenti posizioni di lavoro; Figures 1a, b, c are respective front views of a share according to the present invention in different working positions;

- le figure 2a, b, c sono rispettive viste in pianta delle figure 1a, b, c; e figures 2a, b, c are respective plan views of figures 1a, b, c; And

- le figure 3a, b, c sono rispettive viste prospettiche delle figure 1a, b, c. - figures 3a, b, c are respective perspective views of figures 1a, b, c.

La figura 3a illustra, nel suo insieme, un vomere comprendente una struttura ammortizzante 2 atta ad essere fissata sull’avantreno di un veicolo e un gruppo lama 3 portato dalla detta struttura ammortizzata per spalare neve da una strada. Figure 3a shows, as a whole, a ploughshare comprising a shock-absorbing structure 2 able to be fixed on the front end of a vehicle and a blade assembly 3 carried by said shock-absorbing structure for shoveling snow from a road.

Il gruppo lama 3 comprende un primo e un secondo volvente 4, 5 incernierati rispetto ad un asse A verticale e simmetrico rispetto agli ancoraggi di cui la struttura ammortizzata 2 Ã ̈ provvisto per collegarsi al veicolo, cilindri 6, 7 montati fra la struttura ammortizzata 2 e i rispettivi volventi 4, 5 e gruppi coltelli 8, 9 montati sul rispettivo volvente 4, 5 e prossimi in uso alla strada. The blade assembly 3 comprises a first and a second rolling element 4, 5 hinged with respect to an axis A vertical and symmetrical with respect to the anchors with which the cushioned structure 2 is provided to connect to the vehicle, cylinders 6, 7 mounted between the cushioned structure 2 and the respective rolling elements 4, 5 and knife groups 8, 9 mounted on the respective rolling element 4, 5 and next to the road in use.

Ciascun gruppo coltello 8, 9 comprende un coltello fisso 10 prossimale al relativo volvente 4, 5 e un coltello mobile 11 prossimale in uso alla strada. Each knife assembly 8, 9 comprises a fixed knife 10 proximal to the relative rolling element 4, 5 and a movable knife 11 proximal in use to the road.

In particolare, il coltello mobile 11 Ã ̈ mobile fra una posizione estratta in cui il coltello fisso 10 Ã ̈ interposto fra un bordo inferiore 12 del coltello mobile 11 e il relativo volvente 4, 5 lungo una direzione verticale, e una posizione ritratta in cui il coltello fisso 10 si affaccia direttamente alla strada. In particular, the movable knife 11 is movable between an extracted position in which the fixed knife 10 is interposed between a lower edge 12 of the movable knife 11 and the relative rolling element 4, 5 along a vertical direction, and a retracted position in which the fixed knife 10 faces the street directly.

Il vomere 1 comprende inoltre attuatori idraulici 13 montati fra i volventi 4, 5 e i relativi coltelli mobili 11 comandare il movimento di questi ultimi fra la posizione estratta e quella ritratta. The share 1 further comprises hydraulic actuators 13 mounted between the rolling elements 4, 5 and the relative movable knives 11 to control the movement of the latter between the extracted and retracted position.

Preferibilmente, ciascun coltello mobile 11 à ̈ incernierato a un asse B trasversale, preferibilmente perpendicolare, all’asse A e fisso rispetto al relativo volvente 4, 5. Preferably, each movable knife 11 is hinged to a transverse axis B, preferably perpendicular to the axis A and fixed with respect to the relative rolling element 4, 5.

Ancor più preferibilmente, ciascun coltello 10 à ̈ realizzato di un materiale flessibile comprendente un materiale polimerico e il bordo inferiore 12 à ̈ definito da un materiale rigido, ad esempio metallico. Even more preferably, each knife 10 is made of a flexible material comprising a polymeric material and the lower edge 12 is defined by a rigid material, for example metallic.

Il vomere 1 comprende inoltre una prima e una seconda porzione sagomata 14, 15 interposte in direzione orizzontale fra i volventi 4, 5 e la struttura ammortizzata 2 e disposti per raccordare fra loro i volventi 4, 5. Ciascuna porzione sagomata 14, 15 à ̈ fissa rispetto alla struttura ammortizzata 2 e definisce una porzione di superfici di rotazione rispetto all’asse A. Ad esempio, la porzione sagomata 14 definisce una porzione di una superficie cilindrica e la porzione sagomata 15, disposta da parte opposta dei coltelli 10 11 rispetto alla porzione sagomata 14, definisce una superficie tale che ciascuna sezione lungo un piano contenente l’asse A definisce una linea curva i cui punti presentano una distanza decrescente rispetto all’asse A muovendo verso la porzione sagomata 14. Secondo una forma preferita di realizzazione, ciascun volvente 4, 5 comprende un telaio e una parete 16 realizzata di un materiale polimerico. Il telaio può essere metallico e comprendere una pluralità di traverse 17 e centine 18 che si incrociano per definire una struttura resistente e leggera. Ciascun telaio supporta la relativa parete 16 in modo che quest’ultima definisca una superficie concava per raccogliere e/o evacuare la neve dipendentemente dalla posizione angolare relativa dei volventi 4, 5 rispetto all’asse A. The share 1 also comprises a first and a second shaped portion 14, 15 interposed horizontally between the rolling elements 4, 5 and the cushioned structure 2 and arranged to join together the rolling elements 4, 5. Each shaped portion 14, 15 is fixed with respect to the cushioned structure 2 and defines a portion of surfaces of rotation with respect to the axis A. For example, the shaped portion 14 defines a portion of a cylindrical surface and the shaped portion 15, arranged on the opposite side of the blades 10 11 with respect to to the shaped portion 14, defines a surface such that each section along a plane containing the axis A defines a curved line whose points have a decreasing distance with respect to the axis A moving towards the shaped portion 14. According to a preferred form of embodiment, each rolling element 4, 5 comprises a frame and a wall 16 made of a polymeric material. The frame can be metallic and comprise a plurality of crosspieces 17 and ribs 18 which cross to define a resistant and light structure. Each frame supports the relative wall 16 so that the latter defines a concave surface to collect and / or evacuate the snow depending on the relative angular position of the rolling elements 4, 5 with respect to the axis A.

In particolare, le lame 4, 5 possono essere movimentate l’una rispetto all’altra per definire qualsiasi posizione angolare relativa sia simmetrica che asimmetrica rispetto a una piano di mezzeria passante per l’asse A. Ad esempio, per ottenere tale configurabilità elevata e flessibile, i cilindri 6, 7 sono comandati tramite valvole indipendenti e proporzionali, cioà ̈ aventi come effetto una regolazione continua o considerabile tale della portata di fluido idraulico che comanda i cilindri 6, 7. In particular, the blades 4, 5 can be moved with respect to each other to define any relative angular position, both symmetrical and asymmetrical with respect to a center plane passing through the A axis. For example, to obtain this high and flexible configurability, cylinders 6, 7 are controlled by independent and proportional valves, that is having the effect of continuously or considerably regulating the flow of hydraulic fluid that controls cylinders 6, 7.

In ciascuna posizione, le porzioni sagomate 14, 15 raccordano fra loro le pareti 16 in modo che, in uso, solo un minimo quantitativo di neve sfugge tra i due volventi 4, 5 verso la struttura ammortizzante 2 senza essere deviata lateralmente da questi ultimi. In each position, the shaped portions 14, 15 connect the walls 16 together so that, in use, only a minimum quantity of snow escapes between the two rolling elements 4, 5 towards the shock-absorbing structure 2 without being deflected laterally by the latter.

In particolare, le pareti 16 sono montate a sbalzo sul relativo telaio in modo da esercitare una pressione elastica sulle porzioni sagomate 14, 15 ed aumentare ulteriormente la tenuta contro la neve. In particular, the walls 16 are mounted cantilevered on the relative frame so as to exert an elastic pressure on the shaped portions 14, 15 and further increase the seal against snow.

I vantaggi del vomere secondo la presente invenzione sono i seguenti. The advantages of the share according to the present invention are the following.

La combinazione della struttura a telaio dei volventi 4, 5, del coltello 10 e del coltello mobile 11 rendono il telaio leggero e adatto alle elevate velocità anche per applicazioni ad alte velocità, ad esempio superiori a 30 km/h su strade dove la coltre di neve à ̈ spessa qualche decina di centimetri. Ad elevata velocità, infatti, il coltello mobile 11 à ̈ nella posizione ritratta in modo che eventuali ostacoli sulla strada sono compensati almeno parzialmente dalla deformabilità del coltello 10. The combination of the frame structure of the rolling elements 4, 5, the knife 10 and the movable knife 11 make the frame light and suitable for high speeds even for high speed applications, for example above 30 km / h on roads where the blanket of snow is a few tens of centimeters thick. In fact, at high speed, the movable knife 11 is in the retracted position so that any obstacles on the road are compensated at least partially by the deformability of the knife 10.

La pressione applicata dalle pareti 16 sulle porzioni sagomate 14, 15 definisce una tenuta efficace in modo che i volventi 4, 5 sono configurabili in modo continuo in modo estremamente versatile e sempre efficace. The pressure applied by the walls 16 on the shaped portions 14, 15 defines an effective seal so that the rolling elements 4, 5 can be configured continuously in an extremely versatile and always effective way.

Risulta infine chiaro che al vomere qui descritto e illustrato à ̈ possibile apportare modifiche o varianti senza per questo uscire dall’ambito di tutela come specificato dalle rivendicazioni allegate. Finally, it is clear that it is possible to make changes or variants to the share described and illustrated here without departing from the scope of protection as specified by the attached claims.

In particolare le pareti 16 sono flessibili per esercitare direttamente la pressione sulle porzioni sagomate 14, 15 tramite un’azione elastica oppure comprendono gruppi dedicati che premono sulle porzioni sagomate. In particular, the walls 16 are flexible to directly exert pressure on the shaped portions 14, 15 by means of an elastic action or they comprise dedicated groups which press on the shaped portions.

E’ inoltre possibile prevedere un vomere secondo la parte pre-caratterizzante della rivendicazione 1 e quanto riportato nella rivendicazione 2. In altre parole, à ̈ possibile che il vomere comprenda almeno una porzione sagomata 14, 15, in cui almeno la parete 16 à ̈ configurata in modo da esercitare una pressione sulla porzione sagomata 14, 15 senza che siano presenti i coltelli 10, 11. Anche il telaio 17, 18 può essere o non essere combinato con la parete 16 che comprime le porzioni 14, 15. It is also possible to provide a share according to the pre-characterizing part of claim 1 and what is reported in claim 2. In other words, it is possible that the share includes at least a shaped portion 14, 15, in which at least the wall 16 is It is configured in such a way as to exert a pressure on the shaped portion 14, 15 without the knives 10, 11 being present. The frame 17, 18 may or may not be combined with the wall 16 which compresses the portions 14, 15.
