Abstract

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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An air circulation indicator comprising:
 a rotatable fan blade; and   a support structure for securing the rotatable fan blade substantially adjacent to a vent;   wherein air circulation through the vent rotates the fan blade, thereby indicating the air circulation through the vent.   
     
     
         2 . The air circulation indicator of  claim 1 , wherein the support structure includes a housing assembly. 
     
     
         3 . The air circulation indicator of  claim 2 , wherein the housing assembly is integrally formed with the vent. 
     
     
         4 . The air circulation indicator of  claim 2 , wherein the housing assembly includes attachment means for attaching the housing assembly to the vent. 
     
     
         5 . The air circulation indicator of  claim 4 , wherein the attachment means includes a hook. 
     
     
         6 . The air circulation indicator of  claim 4 , wherein the attachment means removably attaches the housing assembly to the vent. 
     
     
         7 . The air circulation indicator of  claim 1 , wherein the support structure includes a clip attachable to the vent. 
     
     
         8 . The air circulation indicator of  claim 7 , wherein the clip is removably attachable to the vent. 
     
     
         9 . The air circulation indicator of  claim 1 , wherein 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.   
     
     
         10 . An air circulation indicator comprising:
 a rotatable hub;   a rotatable fan blade connected to the rotatable hub for rotating therearound; and   a support structure including a rib for securing the rotatable hub substantially adjacent to a vent;   wherein air circulation through the vent rotates the fan blade, thereby indicating the air circulation through the vent.   
     
     
         11 . The air circulation indicator of  claim 10 , wherein the support structure includes a housing assembly. 
     
     
         12 . The air circulation indicator of  claim 11 , wherein the housing assembly is integrally formed with the vent. 
     
     
         13 . The air circulation indicator of  claim 11 , wherein the housing assembly includes attachment means for attaching the housing assembly to the vent. 
     
     
         14 . The air circulation indicator of  claim 13 , wherein the attachment means includes a hook. 
     
     
         15 . The air circulation indicator of  claim 13 , wherein the attachment means removably attaches the housing assembly to the vent. 
     
     
         16 . The air circulation indicator of  claim 10 , wherein the support structure includes a clip attachable to the vent. 
     
     
         17 . The air circulation indicator of  claim 16 , wherein the clip is removably attachable to the vent. 
     
     
         18 . A method for indicating air circulation comprising:
 providing a rotatable fan blade;   securing, using a support structure, the rotatable fan blade substantially adjacent to a vent;   circulating air through the vent; and   rotating the fan blade in response to the air circulation, thereby indicating the air circulation through the vent.   
     
     
         19 . The method of  claim 18 , further comprising:
 providing a housing assembly with the support structure; and   attaching the housing assembly to the vent.   
     
     
         20 . The method of  claim 19 , wherein the step of attaching includes:
 removably attaching the housing assembly to the vent.
