Title (EN) SKATE BRAKE
(FR) FREIN DE PATIN
Abstract:
(EN) A brake actuator (10) is provided which utilizes either a mechanical or fluid actuation mechanism. The fluid is transferred from an activation reservoir (24) through a tube (34) to an expansion chamber (12) which activates an extendable piston (14) of the brake. The fluid is contained in a closed system and may be biased to a non-braking state so that the wheels will automatically return to their freely rotating state without any further action by the skater after braking. The upper reservoir fits between the liner surrounding the users calf and the back of the skate. The lower reservoir (24) is positioned adjacent the mechanical braking mechanism (10). The lower reservoir (24) is biased so that the fluid returns to the upper reservoir and the brake is deactivated. A buffer can be provided around the upper reservoir to assure even flow through the reservoir and tube (34) and to create a compressible environment. The buffer helps to prevent inadvertent braking and to provide control of the degree of braking. In a mechanical embodiment a piston (80) moves into the expansion chamber.
(FR) L'invention porte sur une commande de frein (10) actionnée soit mécaniquement, soit hydrauliquement. Dans la variante hydraulique, le fluide hydraulique est transféré du réservoir d'actionnement (24) par un tube (34) vers une chambre d'expansion (12) qui agit sur le piston extensible (14) du frein. Le fluide est placé dans un système fermé et peut être rappelé à un état de non freinage où les roues roulent librement sans qu'il soit nécessaire de continuer à agir sur le patin. Le réservoir supérieur est placé entre la doublure entourant le mollet et l'arrière du patin. Le réservoir inférieur (24) est attenant au mécanisme de freinage (10) et il est mis sous pression pour que le fluide retourne au réservoir supérieur, ce qui provoque le desserrage du frein. On peut prévoir un tampon autour du réservoir supérieur pour le système sous pression régularisant le flux à travers le réservoir et le tube (34) et maintenant le système sous pression, empêchant les freinages par inadvertance, et contrôlant l'intensité du freinage. Dans la variante mécanique, le piston (80) se déplace dans la chambre d'expansion.
