Title (EN) A SHOE AND A SOLE THEREFOR
(FR) CHAUSSURE ET SEMELLE POUR CETTE CHAUSSURE
Abstract:
(EN) A sole for a shoe is disclosed which includes a resilient mid-sole (14) in which first and second flexible containers (18) are inset at the heel and forefoot regions of the sole. The containers are filled with a fluid which provides a cushioning medium and a connecting tube (19) provides a balancing of fluid pressure between the containers (19) as well as cushioning along the pressure path of the foot on the outside edge thereof. The embodiment of the invention also provides a valve formed by ribbed members (16) which constrict tube (19) when pressure is applied to them to trap increase in fluid pressure transferred into the forefoot container on initial heel impact to give an extra platform of resistance under the forefoot for a better push-off and 'kick'.
(FR) L'invention concerne une semelle élastique (14) pour chaussure qui comporte un premier et un second réservoir (18) souples logés au niveau du talon et de l'avant du pied. Ces réservoirs contiennent un fluide d'amortissement et un tuyau de raccordement (19) permet d'équilibrer la pression entre les réservoirs (18) et d'amortir le bord extérieur du pied le long de sa trajectoire de pression. Est également prévu un système de clapet formé d'éléments nervurés (16) qui étranglent le tuyau (19) lorsqu'ils sont soumis à une pression et dont le but est de retenir dans le réservoir avant la pression qui y est transférée lors de l'impact du talon afin d'accroître la résistance sous l'avant du pied et d'améliorer ainsi la poussée et l'impulsion.
