Mullion cover hanger and curtain wall insulation system incorporating the same

Abstract

A mullion cover hanger and a curtain wall insulation system incorporating the mullion cover hanger are provided. The mullion cover hanger includes an elongated main body having hook members extending therefrom. When the mullion cover hanger is attached to a mullion, a mullion cover can be secured to the mullion cover hanger without using electric tools or additional fasteners.

What is claimed is: 
     
         1 . A mullion cover hanger for attaching a mullion cover to a mullion, the mullion cover hanger comprising:
 a main body having a top surface, a bottom surface, a first side edge, and a second side edge; and   a plurality of hook members extending outward relative to the top surface of the main body.   
     
     
         2 . The mullion cover hanger of  claim 1 , wherein a first plurality of hook members is positioned at the first side edge of the main body and a second plurality of hook members is positioned at the second side edge of the main body. 
     
     
         3 . The mullion cover hanger of  claim 2 , wherein each hook member positioned at the first side edge of the main body is parallel to a hook member positioned at the second side edge of the main body. 
     
     
         4 . The mullion cover hanger of  claim 2 , wherein each hook member positioned at the first side edge of the main body is not parallel to a hook member positioned at the second side edge of the main body. 
     
     
         5 . The mullion cover hanger of  claim 2 , wherein the hook members positioned at the first side edge of the main body are spaced equidistantly along the length of the main body, and the hook members positioned at the second side edge of the main body are spaced equidistantly along the length of the main body. 
     
     
         6 . The mullion cover hanger of  claim 1 , wherein the plurality of hook members extend outward relative to the top surface of the main body so as to form an angle between each hook member and the top surface of the main body. 
     
     
         7 . The mullion cover hanger of  claim 6 , wherein the angle between each hook member and the top surface of the main body is at least 45°. 
     
     
         8 . The mullion cover hanger of  claim 6 , wherein the angle between each hook member and the top surface of the main body is 90°. 
     
     
         9 . The mullion cover hanger of  claim 1 , further comprising at least one fastening aperture that extends from the top surface of the main body through the bottom surface of the main body. 
     
     
         10 . The mullion cover hanger of  claim 2 , further comprising at least one fastening aperture that extends from the top surface of the main body through the bottom surface of the main body. 
     
     
         11 . The mullion cover hanger of  claim 10 , wherein at least one fastening aperture is positioned between the first side edge and a centerline of the main body, and at least one fastening aperture is positioned between the second side edge and a centerline of the main body. 
     
     
         12 . The mullion cover hanger of  claim 1 , wherein the hook members are defined by:
 an upper edge that extends outward relative to the top surface of the main body at a first angle from the horizontal;   a lower edge that extends outward relative to the top surface of the main body at a second angle from the horizontal;   a topmost edge; and   a hook edge;   wherein the upper edge terminates at the hook edge;   wherein the lower edge terminates at the topmost edge;   wherein the topmost edge extends toward the top surface of the main body and terminates at the hook edge; and   wherein the first angle is less than the second angle.   
     
     
         13 . The mullion cover hanger of  claim 12 , wherein the first angle is 0° to 50° and the second angle is 20° to 70°. 
     
     
         14 . The mullion cover hanger of  claim 12 , wherein the first angle is 0° to 10° and the second angle is 20° to 40° 
     
     
         15 . The mullion cover hanger of  claim 1 , wherein the hook members extend outward relative to the top surface of the main body by a distance of 2 inches or less. 
     
     
         16 . The mullion cover hanger of  claim 1 , wherein the first side edge comprises at least one concavity and the second side edge comprises at least one concavity. 
     
     
         17 . The mullion cover hanger of  claim 1 , further comprising at least one line of reduced strength on the main body. 
     
     
         18 . The mullion cover hanger of  claim 1 , wherein the plurality of hook members consists of a first hook member positioned at the first side edge and a second hook member positioned at the second side edge.
