Title (EN) AIR CIRCULATION INDICATOR
(FR) INDICATEUR DE CIRCULATION D'AIR
Abstract:
(EN) An air circulation indicator and method of use includes a rotatable fan blade, and a support structure for securing the rotatable fan blade substantially adjacent to a vent, such that air circulation through the vent rotates the fan blade, thereby indicating the air circulation through the vent. The support structure includes a housing assembly. The housing assembly is integrally formed with the vent. Alternatively, the housing assembly includes an attachment mechanism for attaching the housing assembly to the vent. The attachment mechanism includes a hook which removably attaches the housing assembly to the vent. In another alternative, the support structure includes a clip attachable to the vent, wherein the clip is removably attachable to the vent. The support structure includes a rotatable hub attached to the blade, and a rib extending from the hub to the vent for fixing the hub to the vent.
(FR) L'invention concerne un indicateur d'une circulation d'air et un procédé d'utilisation associé, comprenant une pale de ventilateur rotative et une structure de support destinée à fixer la pale de ventilateur rotative sensiblement adjacente à un évent, de sorte que la circulation d'air à travers l'évent fasse tourner la pale de ventilateur, indiquant ainsi la circulation d'air à travers l'évent. La structure de support comprend un ensemble enveloppe. L'ensemble enveloppe est formé d'un seul tenant avec l'évent. Selon une variante, l'ensemble enveloppe comprend un mécanisme de fixation destiné à fixer l'ensemble enveloppe à l'évent. Le mécanisme de fixation comprend un crochet permettant de fixer amovible l'ensemble enveloppe à l'évent. Selon une autre variante, la structure de support comprend une pince pouvant être fixée à l'évent, la pince pouvant être fixée amovible à l'évent. La structure de support comprend un moyeu rotatif fixé à la pale, et une nervure s'étendant du moyeu à l'évent afin de fixer le moyeu à l'évent.
