CA 2321742

A dual action buckle (20) which employs a cable tightening action and a strap tensioning action to tighten two separate portions of a boot, notably a snowboard boot (10). Thus, the boot (10) may be tightened around the foot and/or particular functionalities of the boot (10) may be engaged to a preset condition with one simple buckle closing action. During rest periods when the applied tightening and/or functionalities are not needed, they may be deactivated with one simple buckle opening action, giving relief to the foot, greater ease of walking, etc. The invention includes a primary lever (26), a secondary lever (32) pivotally connected to the primary lever (26) and a pulley (42). The pulley (42) acts to double the cable retraction action of the secondary lever (32). This allows the dual action buckle (20) to be made much smaller than would otherwise be the case.

L'invention concerne une boucle (20) double action qui sert à serrer les câbles et à tendre les sangles de manière à serrer deux parties distinctes d'une chaussure, notamment une chaussure de ski (10). La chaussure de ski (10) peut être fermée autour du pied et/ou des fonctionnalités particulières de la chaussure de ski (10) peuvent être utilisées pour prédéfinir une action de fermeture de boucle. Pendant les périodes de repos, lorsque le resserrement et/ou les fonctionnalités sont jugés nécessaires, ils peuvent être désactivés par le biais d'une seule action d'ouverture, soulageant ainsi le pied et assurant une plus grande aisance lors d'un déplacement, etc. L'invention concerne aussi un premier levier (26), un second levier (32) connecté de manière rotative au levier (26) et une poulie (42). La poulie (42) sert à doubler la rétraction du câble du levier (32). Ainsi, on peut fabriquer une boucle double action (20) beaucoup plus petite que les boucles utilisées actuellement.
