Louver shade assembly

Abstract

A canopy tensioner adapted for use with a louver system wherein the canopy tensioner is mounted in pairs on the short and long arms of rib arm unit that traverse the body of the tensioner via an arm connecting chase is connected to a fiber anchor extrusion (keder) and wherein a rotating a nut positioned on the end of the rib arm unit changes the tension on the shade canopy element of the louver system. In an alternative mode, the tensioner unit is adapted for use with shade canopies, wherein the shade canopy is connected to and supported by poles that are connected by headers that are connected at right angles to rafters; support/connector blockes are positioned in the lumen of the rafter thereby connecting the tensioned to the support structure, and the tensioner is also mechanically connected to the front and rear keders of the shade canopy fabric element.

I claim: 
     
         1 . A canopy tensioner adapted for use with a louver assembly, wherein said canopy tensioner is a member of at least one pair of identical canopy tensioners, and wherein said canopy tensioner comprises a tensioner body, wherein said tensioner body comprises an arm connecting chase that traverses the longitudinal dimension of said tensioner body and further wherein a threaded end of a rib arm unit slidably engages said arm connecting chase, and further wherein a threaded adjustment nut functionally engages said threaded end of said rib arm unit, and further, wherein said adjustment nut contacts the inner face of said tensioner body and wherein said said tensioner body is physically secured to an anchor sleeve extrusion; and finally, wherein said canopy tensioner comprises a camber cable chase, wherein said camber cable chase traverses said body of said canopy tensioner and is parallel to and positioned below said arm connecting chase. 
     
     
         2 . A shade canopy tensioning device comprising a threaded, metallic rod and a tensioning nut, wherein the distal end of said threaded, metallic tensioning rod comprises a keder bolt connector eye, and wherein said shade canopy device further comprises a tension rod chase block, wherein said tension rod chase block comprises a first and a second tension rod chase, wherein said first and said second tension rod chases traverse the length of said tension rod chase block, and further wherein the proximal end of said threaded, metallic tensioning rod is adapted slidably to engage a tensioning rod chase; and further wherein said shade canopy tensioning device comprises a keder connector bolt, and wherein tensioning nut threadedly engages said threaded, metallic tensioning rod, and wherein said threaded, metallic tensioning rod slidably engages and is positioned in said first tensioning rod chase, and wherein said keder connector bolt mechanically engages and is connected to said keder bolt connector eye. 
     
     
         3 . The shade canopy tensioning device of  claim 2  wherein a tensioning rod chase block is positioned in the lumen of each end of at least two rafters, wherein the outside dimensions of said tension rod chase block are functionally equal to the inside dimensions of said lumen of each of said at least two rafters, such that said tension rod chase block is held securely in said lumen of each of said at least two rafters and further wherein a the members of a pair of bolt traverse each of said at least two rafters to further secure said tension rod chase block in said lumen; and further wherein a the members of a pair of metallic, rafter connector rods traverse and connect said at least two rafters and wherein said at least two rafters are connected to and supported by a front and a back header. 
     
     
         4 . The shade canopy tensioning element of  claim 3 , wherein the front header is connected to and supported by a pair of front corner posts and wherein the back headed is supported by a pair of back corner posts. 
     
     
         5 . The shade canopy tensioning element of  claim 4 , wherein the front corner posts and anchored by a rail anchor. 
     
     
         6 . The shade canopy tensioning element of  claim 5 , wherein at least on of the back corner posts is anchored by a double layer anchor. 
     
     
         7 . The shade canopy tensioning element of  claim 5 , wherein the corner posts are anchored by a sleeve anchor.
