Removable attachment and associated telescopic rod

Abstract

The present invention concerns a removable fixing device for a telescopic rail comprising an internal spring ( 3 ) and intended to support a curtain on a window or door frame ( 4 ), said fixing comprising in particular a lug ( 5 ) for attachment on the frame ( 4 ) and separation from the pane, and means of connection with one end of said rail, said connecting means being independent of the lug ( 5 ). According to the invention, said connecting means comprise at least a first holding element ( 61 ) and and a second holding element ( 62 ), each element cooperating with the internal wall of the free end of one of the tubes ( 1, 2 ) forming the telescopic rails and with the internal part of an end piece ( 7, 9 ) intended to cover the free end of said rail.

1 . Fixing device for a telescopic rail comprising an internal spring and adapted to support a curtain on a frame of an opening such as a window or door, said fixing device comprising a lug for attachment on the frame and means for connection with one end of said rail, said connection means being independent of said lug, wherein said connection means comprises at least one first holding element and a second holding element, each element cooperating with the inner wall of the free end of one of the tubes forming the telescopic rail and with the inner wall of an end piece intended to cover the free end of said rail, and in that the first holding element has an outside diameter different from that of the second holding element. 
     
     
         2 . Fixing device according to  claim 1 , wherein the end piece and the connecting means are in a single piece. 
     
     
         3 . Fixing device according to  claim 1 , wherein the end piece comprises an at least partially cylindrical element intended to extend said telescopic rail longitudinally. 
     
     
         4 . Fixing device according to  claim 1 , further comprising a cylindrical connecting piece externally surrounded by said first and said second holding elements and allowing for the first and second holding elements to be aligned coaxially, said cylindrical piece having two zones having two different outside diameters and comprising at least one collar disposed between said two zones. 
     
     
         5 . Fixing device according to  claim 4 , wherein said cylindrical piece further comprises at each end a collar for holding the elastic elements. 
     
     
         6 . Fixing device according  claim 1 , wherein the first and/or second holding element or elements comprises a ring having at least one longitudinal slot over part of its length. 
     
     
         7 . Fixing device according to  claim 1 , wherein the first and/or second holding element or elements comprise a cylindrical compression draw spring. 
     
     
         8 . Fixing device according to  claim 1 , wherein part of said fixing lug cooperates with said connecting means, through a contact situated between the first and second holding elements. 
     
     
         9 . Telescopic rail cooperating with at least two fixing devices according to  claim 1 , wherein the telescopic rail comprises two rigid tubes that fit one in the other, and wherein said internal spring is a self-locking compression draw spring housed inside said tubes at the overlapping ends thereof.
