Sole for footwear that can recover some of the energy generated during walking

摘要

The present invention relates to a sole for footwear capable of recovering a part of the energy generated during walking, said sole comprising at least one energy harvesting means (6), energy harvesting means (6 ) Comprises a tubular body (60) fixed in use having first and second ends (61, 62), a movable part (63) slidable in the tubular body (60) Wherein the energy harvesting means is arranged to generate electrical energy during use, during sliding, after sliding of the movable part (63) with respect to the tubular body (60) fixed during use , The sole further comprises at least one actuator group (7) for the energy harvesting means (6), the actuator group (7) comprises a fluid Comprising at least one fluid circuit comprising at least one first and at least one second tank (71, 72), the first tank (71) being housed in the rear region (2) of the sole and the Wherein at least one first and at least one second joining pipe are housed in a front region of the sole and at least one first tank and at least one second joining pipe, Between a second end (61) of a first tubular body (60) and a second end (62) of a second tank (72) and a tubular body (60) . The first tank (71) has a substantially elongated and curved planar shape.
