Title
(EN) FLOOR TILE
(FR) CARREAU DE SOL
Abstract
(EN) Floor tile (100) comprising a plurality of piezoelectric stacks (1), each of the stacks being made by overlapping a plurality of piezoelectric elements (2) and a first plurality of elastic insulating spacers (3) interposed between each pair of adjacent piezoelectric elements (2); a plurality of plastic containers (6) each one of them being designed to house a corresponding piezoelectric stack (2); at least one box (8) designed to house at least two plastic containers (6). The tile (100) further comprises a body (11) configured to accommodate the at least one box (8) and formed by: an upper surface (12) designed to support a flooring; a pressure transfer element (13), designed to transform the pressure exerted on the upper surface of the body (11) in a uniform compression of all piezoelectric stacks (1) contained therein; a retaining element (14) of the at least one box (8) designed to fix the box (8) inside the body (11); elastic elements designed to promote the release from a compressed configuration to a rest configuration when the pressure exerted on the upper surface of the body (11) is removed and a lower element (15) closing the body (11).
(FR) L'invention concerne un carreau de sol (100) comprenant une pluralité d'empilements piézoélectriques (1), chacun des empilements étant réalisé par chevauchement d'une pluralité d'éléments piézoélectriques (2) et d'une première pluralité d'éléments d'espacement isolants élastiques (3) interposés entre chaque paire d'éléments piézoélectriques adjacents (2) ; une pluralité de récipients en matière plastique (6) dont chacun est conçu pour loger un empilement piézoélectrique correspondant (2) ; au moins une boîte (8) conçue pour loger au moins deux récipients en matière plastique (6). Le carreau (100) comprend en outre un corps (11) conçu pour recevoir la ou les boîtes (8) et formé : d'une surface supérieure (12) conçue pour supporter un plancher ; d'un élément de transfert de pression (13), conçu pour transformer la pression exercée sur la surface supérieure du corps (11) en compression uniforme de tous les empilements piézoélectriques (1) contenu en son sein ; d'un élément de retenue (14) de la ou des boîtes (8) conçu pour fixer la boîte (8) à l'intérieur du corps (11) ; d'éléments élastiques conçus pour favoriser la libération d'une configuration comprimée à une configuration de repos lorsque la pression exercée sur la surface supérieure du corps (11) est retirée et qu'un élément inférieur (15) ferme le corps (11).
