Definitions

  • the invention relates to an anti-skid chain with a running net and a holding device connected to it, which in the assembled state is essentially closed to form a ring abutting an inner side flank of a tire, with one locking part being arranged at each end of the holding device, the two locking parts with one another are connectable, and the running net is tensioned on the outside of the tire by at least one tensioning / holding device.

Abstract

L'invention concerne une chaîne antidérapante comportant une structure réticulaire de roulement (LAU) et un dispositif de retenue (HAL) relié à ladite structure réticulaire, qui, à l'état monté, est fermé sensiblement sous forme d'anneau reposant sur un flanc latéral intérieur (FLA) d'un pneu. Un élément de blocage (VE1, VE2) est disposé, dans chaque cas, aux deux extrémités du dispositif de retenue (HAL). Les deux éléments de fermeture (VE1, VE2) peuvent être interconnectés et la structure réticulaire de roulement (LAU) est mise en tension sur la face extérieure du pneu par au moins un dispositif de contrainte/retenue. Les deux éléments de blocage (VE1, VE2) présentent dans chaque cas une base (BA1, BA2) sous forme de plaque. Il est prévu au moins une languette de retenue (HAZ), en saillie depuis la base (BA1) d'un premier élément de blocage (VE1). Le second élément de fermeture présente une section de retenue (HAB) pouvant entrer en prise avec la languette de retenue (HAZ). En position fermée, les bases (BA1, BA2) sous forme de plaques des deux éléments de blocage (VE1, VE2) sont sensiblement parallèles et à l'état monté, les éléments de blocage (VE1, VE2) sont maintenus en position fermée (SPO) par l'intermédiaire de forces de traction introduites par l'intermédiaire de la structure réticulaire de roulement (LAU), appliquée sur les deux éléments de blocage (VE1, VE2).
