Abstract

La présente invention concerne un type de structure de volet roulant qui peut être retiré ou remonté et abaissé. Cette structure comprend un support, un rideau et une tirette. Le côté supérieur du rideau est fixé au support. L'extrémité de traction de la tirette passe par un dispositif à glissement limité fixé au support. L'autre extrémité de la tirette s'étend jusqu'à l'autre extrémité du rideau depuis la partie inférieure de celui-ci, et elle est reliée à un cône. L'extrémité pointue du cône est enfoncée dans un trou traversant d'un élément de fixation fixé au support, et l'extrémité large du cône est bloquée par serrage à l'extrémité du trou traversant. Une fente ouverte de l'élément de fixation suit la partie latérale du trou traversant et établit la connexion avec cette partie. L'extrémité de fixation de la tirette est reliée audit cône, la tirette étant elle-même maintenue par le cône et par le dispositif de fixation. Lorsqu'une force extérieure s'exerçant sur la tirette dépasse 3 kg, le cône peut se séparer automatiquement du dispositif de fixation en raison de l'élargissement du trou traversant. Cette structure est simple et sûre.
