Grille for a ventilation system

Abstract

A ventilation system having a main housing configured to be positioned adjacent to a wall or ceiling of a room of a building structure, a blower configured to be positioned in the main housing and draw air out of the room of the building structure, and a grille configured to be releasably secured to one of the main housing and the blower to at least partially block view of the blower. The grille has a plate defining an inner side and an opposing outer side and a plurality of legs configured to be removably securable to the plate.

We claim: 
     
         1 . A ventilation system comprising:
 a main housing configured to be positioned adjacent to a wall or ceiling of a room of a building structure,   a blower configured to be positioned in the main housing and draw air out of the room of the building structure, and   a grille configured to be releasably secured to one of the main housing and the blower to at least partially block view of the blower, the grille comprising:
 a plate defining an inner side and an opposing outer side, 
 a plurality of legs configured to be removably securable to the plate, 
   wherein the plurality of legs is configured to space the plate from the wall or ceiling.   
     
     
         2 . The ventilation system of  claim 1 , wherein the plate is flat. 
     
     
         3 . The ventilation system of  claim 1 , wherein the plurality of legs comprises four legs. 
     
     
         4 . The ventilation system of  claim 1 , wherein at least one nub extends from the plate to create a friction fit with at least one leg of the plurality of legs. 
     
     
         5 . The ventilation system of  claim 1 , wherein at least one nub extends from the plate to create a friction fit with at least one leg of the plurality of legs, wherein the plate comprises more nubs than legs. 
     
     
         6 . The ventilation system of  claim 1 , wherein at least one nub extends from the plate at least one leg of the plurality of legs comprises a cylindrical wall with an inner perimeter defining a hollow configured to create a friction fit over the nub. 
     
     
         7 . The ventilation system of  claim 1 , wherein the plate defines a periphery and the grille further defines a rail extending along the plate periphery. 
     
     
         8 . A ventilation system configured to be positioned adjacent to a wall or ceiling of a room of a building structure, the ventilation system comprising:
 a grille configured to be releasably secured to the ventilation system, the grille comprising:
 a plate defining an inner side and an opposing outer side, 
 a plurality of legs configured to be removably securable to the plate, 
   wherein the plurality of legs is configured to space the plate from the wall or ceiling.   
     
     
         9 . The ventilation system of  claim 8 , wherein the plate is flat. 
     
     
         10 . The ventilation system of  claim 8 , wherein the plurality of legs comprises four legs. 
     
     
         11 . The ventilation system of  claim 8 , wherein at least one nub extends from the plate to create a friction fit with at least one leg of the plurality of legs. 
     
     
         12 . The ventilation system of  claim 8 , wherein at least one nub extends from the plate to create a friction fit with at least one leg of the plurality of legs, wherein the plate comprises more nubs than legs. 
     
     
         13 . The ventilation system of  claim 8 , wherein at least one nub extends from the plate and at least one leg of the plurality of legs comprises a cylindrical wall with an inner perimeter defining a hollow configured to create a friction fit over the nub. 
     
     
         14 . The ventilation system of  claim 8 , wherein the plate defines a periphery and the grille further defines a rail extending along the plate periphery. 
     
     
         15 . A stack of grilles configured for a ventilation system, the stack comprising:
 a first grille plate and a second grille plate, and each of the first and second grille plates a plate defining an inner side and an opposing outer side, wherein the first grille plate outer side rests on the second grill plate inner side,   a plurality of legs configured to be removably securable to the plate.   
     
     
         16 . The stack of grilles of  claim 15 , wherein each of the first and second grille plates comprises one or more of a grille spring anchor, a grille spring retainer and a nub extending from the plate inner side, wherein the plate outer side of the first grille rests on the grille spring anchor, the grille spring retainer and/or the nub of the second grille. 
     
     
         17 . The stack of grilles of  claim 15 , wherein the plate of each of the first and second grille plates is rectangular. 
     
     
         18 . The stack of grilles of  claim 15 , wherein at least one nub extends from the plate to create a friction fit with at least one leg of the plurality of legs. 
     
     
         19 . The stack of grilles of  claim 15 , wherein at least one nub extends from the plate to create a friction fit with at least one leg of the plurality of legs, wherein the plate comprises more nubs than legs. 
     
     
         20 . The stack of grilles of  claim 15 , wherein the plate of each of the first and second grilles defines a periphery and a rail extends along the periphery.
