Channel lock filter fastening system for use with an air intake structure

Abstract

A fastening system for applying a covering material over an opening of a structure. At least one elongated rail is secured to a fascia of the structure in extending fashion proximate the opening and exhibits a shape with a forwardly projecting support surface within which is configured a narrowed slot. A plurality of fasteners each include a planar shaped base installable through an accessible end location of each of the rails so as to be traversable along an interior channel defined in the rail. A further rotatable portion of each fastener projects from the base through the outwardly facing slot to be rotated from a first position aligning with and seating over perimeter defined receiving apertures of the covering material to a second position in order to affix the material.

1 . A fastening system for applying, over an opening and surrounding fascia of a structure, a covering material exhibiting a reinforced extending perimeter within which is configured a plurality of receiving apertures, said fastening system comprising:
 at least one elongated rail adapted to being secured to the fascia in extending fashion proximate the opening, said rail exhibiting a three dimensional cross sectional shape with a forwardly projecting support surface within which is configured an outwardly facing narrowed slot; and   a plurality of fasteners each including a planar shaped base installable through an accessible end location of each of said rails and being traversable along an interior channel defined in said rail, a further portion of each fastener projecting from said insertable base through said outwardly facing slot and aligning with and seating over perimeter defined receiving apertures of the covering material in order to affix the material.   
     
     
         2 . The fastening system as described in  claim 1 , further comprising a pair of rails in parallel and horizontally extending fashion along fascia locations of the structure above and below the intake opening. 
     
     
         3 . The fastening system as described in  claim 2 , further comprising a second pair of rails in parallel and vertically extending fashion along additional fascia locations of the structure at opposite sides of the intake opening and such that said rails are arranged in a generally rectangular configuration. 
     
     
         4 . The fastening system as described in  claim 1 , said rail further comprising a modified “U” shape in cross section. 
     
     
         5 . The fastening system as described in  claim 1 , further comprising a plurality of spaced apart apertures defined in a base surface of said rail through which are installed a plurality of screw fasteners. 
     
     
         6 . The fastening system as described in  1 , said projecting portion of each of said fasteners further comprising a twist lock fastener. 
     
     
         7 . The fastening system as described in  claim 1 , said projecting portion of each of said fasteners further comprising a toggle lock fastener. 
     
     
         8 . The fastening system as described in  claim 1 , said projecting portion of each of said fasteners further comprising a hook fastener. 
     
     
         9 . The fastening system as described in  claim 1 , said projecting portion of each of said fasteners further comprising a carabiner fastener. 
     
     
         10 . A fastening system for applying, over an opening and surrounding fascia of a structure, a covering material including either of a flexible or rigid outer reinforced extending perimeter within which is configured a plurality of receiving apertures, said fastening system comprising:
 at least one pair of elongated rails adapted to being secured to the fascia in extending fashion proximate the opening, each of said rails exhibiting a three dimensional cross sectional shape with a forwardly projecting support surface within which is configured an outwardly facing narrowed slot; and   a plurality of fasteners each including a planar shaped base installable through an accessible end location of each of said rails and being traversable along an interior channel defined in said rail, a further rotatable portion of each fastener projecting from said insertable base through said outwardly facing slot and being rotated from a first position aligning with and seating over perimeter defined receiving apertures of the covering material to a second position in order to affix the material.   
     
     
         11 . The fastening system as described in  claim 10 , said rails each further comprising a modified “U” shape in cross section. 
     
     
         12 . The fastening system as described in  claim 10 , further comprising a plurality of spaced apart apertures defined in a base surface of said rail through which are installed a plurality of screw fasteners. 
     
     
         13 . The fastening system as described in  10 , said projecting portion of each of said fasteners further comprising a twist lock fastener. 
     
     
         14 . The fastening system as described in  claim 10 , said projecting portion of each of said fasteners further comprising a toggle lock fastener. 
     
     
         15 . A fastening system for applying, over an opening and surrounding fascia of a structure, a covering material exhibiting a reinforced extending perimeter within which are configured a plurality of spaced apart grommets defining individual receiving apertures, said fastening system comprising:
 at least one elongated rail adapted to being secured to the fascia in extending fashion proximate the opening, said rail exhibiting a three dimensional cross sectional shape with a forwardly projecting support surface within which is configured an outwardly facing narrowed slot;   a plurality of fasteners each including a planar shaped base installable through an accessible end location of each of said rails and being traversable along an interior channel defined in said rail, a further portion of each fastener projecting from said insertable base through said outwardly facing slot and aligning with and seating over selected grommets in the covering material in order to affix the material; and   said fasteners being quickly positioned in alignment with the receiving apertures associated with the covering material thus permitting self-alignment of said fasteners relative to the grommets thereby reducing wrinkling of the covering material during installation.   
     
     
         16 . The fastening system as described in  claim 15 , further comprising a pair of rails in parallel and horizontally extending fashion along fascia locations of the structure above and below the intake opening. 
     
     
         17 . The fastening system as described in  claim 16 , further comprising a second pair of rails in parallel and vertically extending fashion along additional fascia locations of the structure at opposite sides of the intake opening and such that said rails are arranged in a generally rectangular configuration. 
     
     
         18 . The fastening system as described in  claim 15 , further comprising a plurality of spaced apart apertures defined in a base surface of said rail through which are installed a plurality of screw fasteners. 
     
     
         19 . The fastening system as described in  15 , said projecting portion of each of said fasteners further comprising a twist lock fastener. 
     
     
         20 . The fastening system as described in  claim 15 , said projecting portion of each of said fasteners further comprising a toggle lock fastener.
