Upper frame for a vertical venetian blind

Abstract

An upper frame for a vertical Venetian blind includes a horizontal rod and a slide rail. The horizontal rod is formed axially with at least two rod portions, and the slide rail is axially formed with at least two slide rail portions. The rod portions can be connected together to make up the horizontal rod and the slide rail portions can be connected together to make up the slide rail. The rod portions and the slide rail portions are separable or collapsible before they are assembled, able to be packed with less space to save cost in packing, storing and transporting.

1 . An upper frame for a vertical Venetian blind comprising a horizontal rod, said horizontal rod provided with a slide rail in the interior, said slide rail fitted thereon with a plurality of slide blocks preset in number, said slide blocks actuated to slide horizontally on said slide rail by a control cord provided at one end of said horizontal rod: 
 Said horizontal rod formed axially with at least two rod portions, said rod portions able to be connected with each other to make up said horizontal rod: and    Said slide rail formed axially with at least two slide rail portions, said slide rail portions able to be connected with each other to make up said slide rail.    
   
   
       2 . The upper frame for a vertical Venetian blind as claimed in  claim 1 , wherein said rod portions are connected together by means of an outer connecting member and an inner connecting member, said outer connecting member having its upper inner side provided with plural engage blocks and elastic fitting projections, said rod portions having their a butting ends respectively bored with an engage groove, said rod portions having their upper jointing portions bored with a notch, said engage blocks on the inner sides of said outer connecting member respectively engaged with said two engage grooves of said two rod portions, said two elastic fitting projections of said outer connecting member positioned in said notch of said two rod portions, said inner connecting member having its outer side bored with two engage grooves, said elastic fitting projections of said outer connecting member respectively engaged with said engage grooves of said inner connecting member when said inner connecting member closely positioned on the inner sides of said two rod portions, said two rod portions fixedly sandwiched by said outer and said inner connecting member and connected together.  
   
   
       3 . The upper frame for a vertical Venetian blind as claimed in  claim 1 , wherein one of said two rod portions has its connecting end formed with two insert grooves, and the other of said rod portions has its connecting end formed with two projections to be engaged with said two insert grooves so as to connect said two rod portions.  
   
   
       4 . The upper frame for a vertical Venetian blind as claimed in  claim 1 , wherein said two rod portions are connected together by a hinge and a locking member, said hinge secured at the abutting ends of one side of said two rod portions, said locking member secured at the abutting ends of the other side of said two rod portions.  
   
   
       5 . The upper frame for a vertical Venetian blind as claimed in  claim 1 , wherein said two slide rail portions are connected together by a connecting rod, said connecting rod having its intermediate part formed with a connecting section, said connecting section having the same cross-sectional figuration and size as those of said slide rail, said connecting section having its opposite ends respectively extending horizontally and forming insert ribs preset in number, said two slide rail portions bored with insert grooves preset in number at the location corresponding to said connecting rod, said connecting rod having said insert ribs at the opposite ends respectively inserted in said insert grooves of said slide rail portions so as to let the opposite ends of said connect section of said connecting rod push against the opposite ends of said two slide rail portions.  
   
   
       6 . The upper frame for a vertical Venetian blind as claimed in  claim 1 , wherein one of said two slide rail portion has its end formed with a projection, and the other one has its end formed with a hole matching with said projection, said projection and said insert hole engaged with each other to connect said slide rail portions together.  
   
   
       7 . The upper frame for a vertical Venetian blind as claimed in  claim 1 , wherein said slide rail portions are connected together by a connecting rod, said connecting rod having a smaller diameter than said slide rail, said slide rail portions respectively bored with a hole at a location corresponding to said connecting rod, said connecting rod having two ends respectively inserted in said two holes at the opposite ends of said two slide rail portions.
