Window blind structure

Abstract

A window blind structure comprises a blind body and a set of left/right support brackets wherein the blind body is folded into a U shape with a winding shaft and a hanging rod respectively attached at both end edges thereto, and a counterweight object accommodated into the bending area for even suspension of the blind body thereby. Each left/right support bracket has a grooved area with a fixing surface at one side, and an extension portion at the other side wherein one extension portion has crosswise retaining recesses cut thereon, and the other pivoting holes disposed thereon for holding the winding shaft there-between. Around four side corners of each extension portion are respectively disposed a thru-hole accompanied by first and second positioning blocks to match with an adjusting support member that can flexibly change the direction of assembly, achieving more versatile and convenient assembly of the left/right support brackets thereby.

1 . A window blind structure, comprising a blind body and a set of left and right support brackets wherein the blind body is extended and bent into a U-shaped configuration to form a first shade section and a second shade section each made up of a plurality of light-permeable areas and light-shading areas alternatively arranged to one another at the surface thereon respectively; at both end edges of the blind body are respectively attached a winding shaft and a hanging rod, and a counterweight object is accommodated into the bending area of the folded blind body so as to keep even and neat suspension of the first and second shade sections thereby; each of the left/right support brackets is made up of a grooved area with a fixing surface defining one sidewall to be mounted to a wall surface thereby, and an extension portion stretching outwards in perpendicular to the other sidewall of the grooved area thereof; one extension portion of the left/right support brackets is defined by a plurality of retaining recesses, and the other extension portion of the left/right support brackets is correspondingly provided with multiple pivoting holes so that a positioning rib of a covering and a pivoting post of a linkage body mounted at both end edges of the winding shaft can be respectively joined therewith; around four side corners of each extension portion thereof are respectively disposed a thru-hole accompanied at two adjacent sides by a first positioning block and a second positioning block to cooperatively work with an adjusting support member having an adjustment slot disposed thereon; therefore, depending on the position of the left/right support bracket mounted to a vertical/horizontal wall surface, the adjusting support member can flexibly change the direction of assembly onto the extension portion of the left/right support bracket, and a retaining cavity is indented at one side of the adjusting support member for the mounting of the hanging rod therein.  
     
     
         2 . The window blind structure as claimed in  claim 1  wherein the hanging rod can be made in a hollow tube.  
     
     
         3 . The window blind structure as claimed in  claim 1  wherein both end edges of the hanging rod have a coupling port disposed therein respectively to be cooperatively associated with a support fitting thereby.  
     
     
         4 . The window blind structure as claimed in  claim 3  wherein the support fitting is made up of a coupling section of smaller diameter disposed at one end, and a support section of identical diameter to the hanging rod with an annular coupling groove indented in the middle section thereon.  
     
     
         5 . The window blind structure as claimed in  claim 1  wherein the grooved area of the left/right support bracket can be formed in a U-shaped configuration.  
     
     
         6 . The window blind structure as claimed in  claim 1  wherein the fixing surface of the left/right support bracket has a plurality of locking holes disposed thereon.  
     
     
         7 . The window blind structure as claimed in  claim 1  wherein each of the retaining recesses defining one extension portion of the left/right support brackets is made in a U shape and connected to each other to form a crosswise configuration thereby.  
     
     
         8 . The window blind structure as claimed in  claim 1  wherein the first positioning block of the left/right support bracket is horizontally aligned adjacent to each thru-hole thereof.  
     
     
         9 . The window blind structure as claimed in  claim 1  wherein the second positioning block of the left/right support bracket is vertically aligned adjacent to each thru-hole thereof.
