Abstract

La présente invention concerne un appareil porteur et amortisseur de chocs qui comprend un premier et un second élément porteur (12, 14), apte chacun à recevoir au moins un élément ressort comprimable (16) en contact opérationnel, tournant, flottant. Les éléments ressorts comprimables (12, 14) comprennent un premier et un second panneau arqué (18, 24) qui sont contigus l'un à l'autre en leurs extrémités proximales respectives et orientés de façon qu'ils forment un V biconcave. L'invention comprend une semelle porteuse et amortisseuse de chocs pour chaussures, dans laquelle le premier et le second élément porteur (12, 14) sont aptes chacun à recevoir une pluralité d'éléments ressorts comprimables (16) en contact opérationnel, tournant, flottant. Le contact flottant, tournant en une pluralité de points le long de la semelle permet un réalignement constant des deux surfaces porteuses de la semelle en réponse aux charges qui lui sont appliquées. Par conséquent, l'invention permet, par un amortissement des chocs indépendant, de stabiliser et compenser les charges qui sont appliquées de manière décentrée ou selon des angles qui ne sont pas verticaux par rapport à l'un ou l'autre des éléments porteurs.
