Wooden vent cover

Abstract

A wooden vent cover has fixed vanes with major vane surfaces at angles which enhance the throw and spread of air flow through the vent cover. A vent assembly with a wooden vent cover having optimized vane major surface angles including an air flow regulator in combination with the wooden vent cover. The air flow regulator may be a slidable member or other configuration and may be held in place by couplers.

1 . A wooden vent cover for covering a vent opening, the wooden vent cover comprising: 
 a wooden vent cover body, the wooden vent cover body comprising opposed front and back surfaces and, wherein the front surface is exposed when the wooden vent cover is positioned to cover the vent opening;    a plurality of spaced apart wooden vanes supported by the body so as to not pivot relative to the body, at least a plurality of the vanes having air flow openings provided between the vanes, the vanes each comprising opposed first and second major vane surfaces which are positioned at an angle which is about sixteen degrees in either direction from a first plane which is perpendicular to a second plane defined by the front surface of the vent cover body; and    an air flow regulator which is slidably coupled to the wooden vent cover for sliding relative to the back surface of the wooden vent cover from a first closed position in which the air flow regulator substantially blocks the flow of air through the air flow openings to second open positions in which air flow paths are provided through the air flow regulator and through the air flow openings.    
   
   
       2 . A wooden vent cover for covering a vent opening, the wooden vent cover comprising: 
 a wooden vent cover body, the wooden vent cover body comprising opposed front and back surfaces and, wherein the front surface is exposed when the wooden vent cover is positioned to cover the vent opening;    a plurality of spaced apart wooden vanes supported by the body so as to not pivot relative to the body, at least a plurality of the vanes having air flow openings provided between the vanes, the vanes each comprising opposed first and second major vane surfaces which are positioned at an angle which is from about twelve degrees to about seventeen degrees in either direction from a first plane which is perpendicular to a second plane defined by the front surface of the vent cover body; and    wherein all of the vanes of the wooden vent cover have first and second major vane surfaces which are parallel and are at the same angle from the first plane.    
   
   
       3 . A wooden vent cover according to  claim 2  wherein the angle is sixteen degrees.  
   
   
       4 . A wooden vent cover for covering a vent opening, the wooden vent cover comprising: 
 a wooden vent cover body, the wooden vent cover body comprising opposed front and back surfaces and, wherein the front surface is exposed when the wooden vent cover is positioned to cover the vent opening; and    a plurality of spaced apart wooden vanes supported by the body so as to not pivot relative to the body, at least a plurality of the vanes having air flow openings provided between the vanes, the vanes each comprising opposed first and second major vane surfaces which are positioned at an angle which is from about twelve degrees to about seventeen degrees in either direction from a first plane which is perpendicular to a second plane defined by the front surface of the vent cover body.    
   
   
       5 . A wooden vent cover according to  claim 4  wherein the angle is from 11.9 degrees to 17.3 degrees in either direction.  
   
   
       6 . A wooden vent cover according to  claim 4  wherein the angle is sixteen degrees in either direction from the first plane.  
   
   
       7 . A wooden vent cover according to  claim 4  comprising a first set of a plurality of vanes which each have first and second major vane surfaces which are parallel and at a first angle in a first direction from the first plane and a second set of a plurality of vanes which each have first and second major vane surfaces which are parallel and at a second angle in a second direction opposite to the first direction from the first plane.  
   
   
       8 . A wooden vent cover according to  claim 7  wherein the first and second angles are each sixteen degrees.  
   
   
       9 . A wooden vent cover according to  claim 7  wherein the wooden vent cover body comprises a vane receiving opening and at least one divider which separates the vane receiving opening into first and second side-by-side openings, the first set of vanes being supported to extend within the first opening at one side of the divider and the second set of vanes being positioned to extend within the second opening at the opposite side of the divider.  
   
   
       10 . A wooden vent cover according to  claim 9  wherein the first and second angles are each sixteen degrees.  
   
   
       11 . A wooden vent cover according to  claim 9  wherein the wooden vent cover body is rectangular and the first and second side-by-side openings are also each rectangular.  
   
   
       12 . A wooden vent cover according to  claim 9  wherein the divider has respective first and second major air flow side surfaces which are at the same angle as an adjacent major vane surface.  
   
   
       13 . A wooden vent cover according to  claim 4  comprising an air flow regulator which is slidably coupled to the wooden vent cover for sliding relative to the back surface of the wooden vent cover from a first closed position in which the air flow regulator substantially blocks the flow of air through the air flow openings to second open positions in which air flow paths are provided through the air flow regulator and through the air flow openings.  
   
   
       14 . A wooden vent cover according to  claim 13  comprising plural detachable clips slidably coupling the air flow regulator to the wooden vent cover.  
   
   
       15 . A vent cover comprising: 
 a wooden vent cover comprising a wooden vent cover face and plural fixed vanes with vane surfaces angled to provide a sum total of one-half of the maximum total spread plus the maximum throw of at least 77 inches, wherein, with air flow exiting at the face of the wooden vent cover at five hundred feet per minute, the maximum throw is defined as being the maximum distance in a direction perpendicular to the wooden vent cover face where the flow rate has dropped to fifty feet per minute and the maximum total spread being the maximum distance in both directions parallel to the wooden vent cover face where the flow rate has dropped to fifty feet per minute;
