Abstract

Un elemento di rullo per uno scivolo, comprendente un cilindro esterno, un tubo interno e dei mezzi connettori per realizzare i collegamenti fra detti componenti i quali sono tutti formati integralmente in un materiale dotato di un'adeguata elasticità, resistenza ad usura, resistenza agli agenti atmosferici ecc.; in cui il cilindro esterno ha uno spessore sufficiente a renderlo deformabile, e sono previsti mezzi intercalari leggermente più corti dello spazio formato fra il cilindro esterno e il tubo interno, allo scopo di limitare l'entità della deformazione del cilindro esterno, e delle nervature, in alternativa ai mezzi connettori, le quali si collegano al cilindro esterno e al tubo interno su di un lato a diametro ridotto del cilindro esterno, e si collegano al solo tubo interno su di un lato a diametro maggiore del cilindro esterno, così da definire un intervallo di circa 2-3 mm fra il bordo esterno del tubo interno e la faccia interna del cilindro esterno.A roller element for a chute, comprising an external cylinder, an internal tube and connector means for making the connections between said components which are all integrally formed in a material with adequate elasticity, wear resistance, resistance to agents atmospheric etc .; wherein the outer cylinder has a thickness sufficient to make it deformable, and interlayer means slightly shorter than the space formed between the outer cylinder and the inner tube are provided, in order to limit the extent of deformation of the outer cylinder, and of the ribs, as an alternative to the connector means, which connect to the external cylinder and the internal tube on one side with a reduced diameter of the external cylinder, and connect to the internal tube only on one side with a larger diameter of the external cylinder, so as to define a interval of about 2-3 mm between the outer edge of the inner tube and the inner face of the outer cylinder.
