Device for hanging a curtain in front of a window

Abstract

The device includes two sub-assemblies ( 1 ) for mounting the rail ( 2 ) for supporting the curtain on the leaves ( 3 ) of the window, each sub-assembly having a plate ( 5 ) and an offset arm ( 6 ). The plate is formed so as to be able to be fixed to the upper edge of a leaf ( 3 ), in the vicinity of the pivot axis thereof, and includes mounting elements ( 14 ) for pivotably mounting the offset arm thereon, along an axis extending, after mounting on the leaf ( 3 ), parallel to the pivot axis of the leaf. The offset arm ( 6 ) is formed to offset the rail ( 2 ) relative to the wall; it is pivotably mounted on the plate ( 5 ) by the mounting elements and is pivotably connected to the rail ( 2 ) at a point thereof which is longitudinally fixed, also along an axis parallel to the pivot axis of the leaf ( 3 ).

1 . Device for hanging a curtain in front of a window, characterized in that it comprises two sub-assemblies ( 1 ) for mounting the rail ( 2 ) for supporting the curtain on the leaves ( 3 ) of the window, each sub-assembly ( 1 ) comprising a plate ( 5 ) and an offset arm ( 6 ); the plate ( 5 ) is formed so as to be able to be fixed to the upper edge of a leaf ( 3 ), in the vicinity of the pivot axis thereof, and comprises mounting means ( 14 ) for the pivotable mounting of the offset arm ( 6 ) thereon, along an axis extending, after mounting on the leaf ( 3 ), parallel to the pivot axis of the leaf ( 3 ); the offset arm ( 6 ) is formed to offset the rail ( 2 ) relative to the wall; it is pivotably mounted on the plate ( 5 ) by means of said mounting means and is pivotably connected to the rail ( 2 ) at a point thereof which is longitudinally fixed, also along an axis parallel to the pivot axis of the leaf ( 3 ). 
   
   
       2 . Device according to  claim 1 , characterized in that at least one plate ( 5 ) comprises an abutment member ( 13 ) and in that the corresponding offset arm ( 6 ) also comprises an abutment member ( 15 ), these two abutment members ( 13 ,  15 ) being arranged so as to come into abutment against one another in the closed position of the leaf ( 3 ). 
   
   
       3 . Device according to  claim 2 , characterized in that the plates ( 5 ) and the offset arms ( 6 ) of the two sub-assemblies ( 1 ) each comprise abutment members ( 13 ,  15 ) as mentioned above. 
   
   
       4 . Device according to  claim 1 , characterized in that the means for the pivotable mounting of an offset arm ( 6 ) on the corresponding plate ( 5 ) are formed by a pin ( 14 ) integral with the plate ( 5 ) and by a bore made in each offset arm ( 6 ), this bore allowing the pivotable engagement of the offset arm on the pin ( 14 ). 
   
   
       5 . Device according to  claim 2 , characterized in that the abutment member of each plate ( 5 ) is formed by a pin ( 13 ) integral with each plate ( 5 ) and in that the abutment member of the corresponding offset arm ( 6 ) is formed by a projection ( 15 ) projecting radially from this offset arm ( 6 ), this projection ( 15 ) preferably being integral with this offset arm ( 6 ). 
   
   
       6 . Device according to  claim 1 , characterized in that each plate ( 5 ) comprises means for adjusting the position of the pivotable mounting means of the offset arm ( 6 ), these adjusting means being able to be adjusted such that the pivot axis of the offset arm ( 6 ) is merged with the pivot axis of the leaf ( 3 ) on which the plate ( 5 ) is mounted. 
   
   
       7 . Device according to  claim 6 , characterized in that means are provided for limiting the pivoting of each offset arm ( 6 ) relative to the rail ( 2 ). 
   
   
       8 . Device according to  claim 1 , characterized in that when a leaf ( 3 ) comprises an upper rebate ( 10 ), the plate ( 5 ) intended to be fixed to this leaf ( 3 ) is formed and dimensioned to be able to be engaged to overlap, in a close-fitting manner, the projecting edge ( 3   a ) of the leaf ( 3 ) which defines the rebate ( 10 ). 
   
   
       9 . Device according to  claim 8 , characterized in that each plate ( 5 ) comprises a tapped bore ( 11 ) being able to receive an adjusting screw ( 12 ) capable of bearing against the leaf ( 3 ) without penetrating the material thereof. 
   
   
       10 . Device according to  claim 1 , characterized in that each sub-assembly ( 1 ) comprises means ( 19 ,  20 ) for adjusting the height of the rail ( 2 ) relative to the leaf ( 3 ). 
   
   
       11 . Device according to  claim 2 , characterized in that the means for the pivotable mounting of an offset arm ( 6 ) on the corresponding plate ( 5 ) are formed by a pin ( 14 ) integral with the plate ( 5 ) and by a bore made in each offset arm ( 6 ), this bore allowing the pivotable engagement of the offset arm on the pin ( 14 ). 
   
   
       12 . Device according to  claim 2 , characterized in that each plate ( 5 ) comprises means for adjusting the position of the pivotable mounting means of the offset arm ( 6 ), these adjusting means being able to be adjusted such that the pivot axis of the offset arm ( 6 ) is merged with the pivot axis of the leaf ( 3 ) on which the plate ( 5 ) is mounted. 
   
   
       13 . Device according to  claim 2 , characterized in that when a leaf ( 3 ) comprises an upper rebate ( 10 ), the plate ( 5 ) intended to be fixed to this leaf ( 3 ) is formed and dimensioned to be able to be engaged to overlap, in a close-fitting manner, the projecting edge ( 3   a ) of the leaf ( 3 ) which defines the rebate ( 10 ).
