DISPOSITIVO A CATENE DA NEVE DI RAPIDA APPLICAZIONE AI PNEUMATICI SNOW CHAIN DEVICE FOR QUICK APPLICATION TO TIRES

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

L'invenzione concerne un nuovo dispositivo costituito da catene da neve strutturate in modo tale da essere applicate ai pneumatici in modo semplice e rapido. The invention relates to a new device consisting of snow chains structured in such a way as to be applied to tires simply and quickly.

Sono note le attuali difficoltà che gli automobilisti trovano allorchè sono costretti a montare le catene da neve, richiedenti complesse e numerose procedure di aggancio e fissaggio, in particolare durante condizioni atmosferiche avverse. The current difficulties that motorists encounter when they are forced to mount snow chains, which require complex and numerous hooking and fixing procedures, are known, in particular during adverse weather conditions.

Scopo dell'invenzione è quello di risolvere completamente le suddescritte negatività con un dispositivo applicabile ai pneumatici in tempi molto ridotti e tale da risultare ad alta fhzionalità. The object of the invention is to completely solve the aforementioned negativities with a device applicable to tires in a very short time and such as to be highly functional.

Lo scopo si raggiunge con il dispositivo secondo l'invenzione comprendente catene da neve costituite da coppie di elementi applicabili e fissabili ad ogni pneumatico, in modo tale da ottenerne la copertura completa. The object is achieved with the device according to the invention comprising snow chains consisting of pairs of elements that can be applied and fixed to each tire, in such a way as to obtain complete coverage.

In una possibile variante strutturale il dispositivo risulta costituito da un solo elemento allo stesso scopo. In a possible structural variant, the device consists of a single element for the same purpose.
