Patent

CA 2608346

Non-slipping wheel (1) comprising an elastomer layer (3) which covers at least the radially outer part of the wheel, characterized in that the elastomer layer has been provided with bubbles which are continuously torn open during use of the wheel thereby generating a suction effect. The buttles can be provided by foaming the elastomer. The elastomer can be polyurethane, and the wheel can further comprise an inner core layer (2) of a different material which is elastic, e.g., rubber. The wheel is particularly useful for floor cleaning machines: due to their use on ground which is covered by a cleaning solution, the wheels face traction problems - on the other hand, the wheels should not leave additional residues or markings on the floor.

L~invention concerne une roue antidérapante (1) comprenant une couche élastomère (3) recouvrant au moins la partie radialement externe de la roue, caractérisée en ce que la couche élastomère est pourvue de bulles qui sont déchirées en permanence pendant l~utilisation de la roue, générant ainsi un effet d~aspiration. Les bulles s~obtiennent par moussage de l~élastomère. L~élastomère peut être du polyuréthane, et la roue peut comprendre en outre une couche centrale interne (2) d~un matériau différent qui est élastique, par exemple du caoutchouc. La roue s~utilise en particulier pour les machines nettoyage des sols : du fait de leur emploi sur un sol recouvert d~une solution de nettoyage, les roues rencontrent des problèmes de traction - par ailleurs, les roues ne doivent pas laisser de résidus ni de marques supplémentaires sur le sol.
