Abstract

L'invention porte sur un dispositif volant qui génère une force de flottement en déplaçant vers le haut et vers le bas une paire d'ailes, ce dispositif étant notamment actionné par l'homme. Le mouvement vertical des ailes pouvant être facilement obtenu par une force limitée, le flottement peut alors s'exercer efficacement et le battement peut s'effectuer sur une longue durée. Ce dispositif volant à mouvements de battement comprend un organe unidirectionnel d'ouverture/fermeture placé sur les deux ailes de façon à supporter les deux ailes, droite et gauche, de sorte qu'elles battent dans le sens vertical, une ouverture pour permettre le passage de l'air lorsqu'elles se déplacent vers le haut et une fermeture pour empêcher l'air de passer lorsque les ailes sont en mouvement. Une structure pliable médiane de raccordement permet de supporter pivotante une barre latérale du corps principal supportée pivotante par un cadre inférieur placé sous les parties supports des deux ailes pourvues de barres latérales supportées pivotantes sur le côté du cadre support des deux ailes; et une partie de commande telle qu'un dispositif de préhension placé près d'une partie de raccordement entre la barre latérale du corps principal et la barre latérale de l'aile.
