Skylight system

Abstract

A skylight system ( 10 ) including a prefabricated mounting frame ( 20 ) and a prefabricated hood assembly ( 25 ), adapted to assemble together to form a skylight ( 10 ).

1 . A skylight system including a prefabricated mounting frame and a prefabricated hood assembly, adapted to assemble together to form a skylight.  
   
   
       2 . The skylight system of  claim 1  wherein, said prefabricated mounting frame comprises a rectangular arrangement of extruded sections to form a rectangular support structure.  
   
   
       3 . The skylight system of  claim 2  wherein, said extruded sections are provided with bottom flange portions adapted to seat on the batten timbers of a sloping roof.  
   
   
       4 . The skylight system of  claim 2  wherein, said extruded sections are provided with a pair of closely spaced projecting flanges adapted to accept and retain pre-assembled flashing elements attached to said extruded sections.  
   
   
       5 . The skylight system of  claim 4  wherein, said flashing elements along the two sloping sides of said skylight, comprise roll-formed metal strips, said roll-formed strips adapted to interface with roof covering material.  
   
   
       6 . The skylight system of  claim 4  wherein, said flashing elements along the two horizontal sides of said skylight comprise malleable metal strips.  
   
   
       7 . The skylight system of  claim 2  wherein, said prefabricated mounting frame is provided with sprung retainer elements attached to each of the extruded elements forming the sides of said rectangular support structure.  
   
   
       8 . The skylight system of  claim 7  wherein, said sprung retainer elements are in the form of bent metal strips with the lower ends of said strips forming an angle with said sides of said rectangular support structure, such that said lower ends deflect inwardly from said sides.  
   
   
       9 . The skylight system of  claim 3  wherein said extruded members are provided with an horizontal ledge extending outwardly from said extruded members, said horizontal ledge adapted to support a sealing strip, said sealing strip forming a perimeter seal around the top of said prefabricated mounting frame.  
   
   
       10 . The skylight system of  claim 1  wherein, said prefabricated hood assembly includes perimeter capping, glass layers, internal sash frame, extruded seal elements and extruded clamping members.  
   
   
       11 . The skylight system of  claim 10  wherein, said perimeter capping is fabricated from extruded elements adapted to provide framing of said glass layers and support for said clamping members.  
   
   
       12 . The skylight system of  claim 11  wherein, said internal sash frame is retained within said perimeter capping by said clamping members, said clamping members provided with a clamping ledge adapted to engage in grooves provided in the outer faces of said internal sash frame.  
   
   
       13 . The skylight system of  claim 10  wherein, said extruded seal elements provide support for said glass layers.  
   
   
       14 . The skylight system of  claim 10  wherein, said glass layers are clamped between said perimeter capping, said extruded seal elements and said internal sash frame by said clamping members.  
   
   
       15 . The skylight system of  claim 14  wherein, said clamping members are fastened to said perimeter capping by self tapping screws.  
   
   
       16 . The skylight system of  claim 1  wherein, said prefabricated hood assembly is adapted for assembly with said prefabricated mounting frame so that said internal sash frame locates within said prefabricated mounting frame; said clamping members seating on said perimeter seal.  
   
   
       17 . The skylight system of  claim 16  wherein, said prefabricated hood assembly is retained in sealing engagement with said prefabricated mounting frame by means of said sprung retainer elements engaging in recesses provided in the outer surfaces of said internal sash frame.  
   
   
       18 . The skylight system of  claim 15  wherein, said prefabricated mounting frame is provided with an extruded hinge section; said hinge section adapted to be a clip-on attachment to one of said extruded sections of said prefabricated mounting frame.  
   
   
       19 . The skylight system of  claim 18  wherein, said hinge section includes an extruded lobe element, said lobe element being of substantially circular section and further including a convex extruded arcuate guide segment concentric with said lobe element.  
   
   
       20 . The skylight system of  claim 19  wherein, at least one of said extruded elements of said perimeter capping of said prefabricated hood assembly includes an extruded hinge element of partially cylindrical form and a concave extruded arcuate guide segment concentric with said hinge element, said hinge element and said concave extruded arcuate guide segment adapted to mate with said lobe element and said convex extruded arcuate guide segment so as to allow rotation of said prefabricated hood assembly about said lobe element when one of said extruded hinge elements of said perimeter capping is assembled with said lobe element.
