Abstract

L'invention concerne un amortisseur et une semelle de poussée propulsive pour chaussure. La semelle intercalaire de chaussure est constituée d'un châssis supérieur (figure 1; détail 2) et d'un châssis inférieur (figure 1, détail 3) présentant un évidement (figure 1; détail 4) entre eux, le volume de ladite semelle pouvant subir une déformation élastique. Une ou plusieurs pièces élastiques (figure 1; détails 5 et 6) sont placées à l'intérieur de l'évidement. Les pièces élastiques se compriment pendant la phase de choc du pied et se dilatent pendant le décollement des orteils, avec un effet de poussée propulsive. Pour obtenir l'effet avec plus d'efficacité, un mécanisme de verrouillage relie le châssis supérieur au châssis inférieur. Ledit mécanisme de verrouillage active le bloc dans la phase de choc du pied lorsque la charge de compression maximale est atteinte dans l'arrière de la semelle intermédiaire. Le mécanisme de verrouillage libère le mécanisme au cours de la phase de décollement des orteils lorsqu'une charge de compression est appliquée sur l'avant de la semelle intercalaire, en soutien de la poussée propulsive. L'invention a pour objet d'améliorer l'efficacité et le confort de la semelle ainsi que de la chaussure elle-même.
