Adjustable mounting bracket for sun screens

Abstract

Mounting brackets ( 1 ) that have to be fitted in an aligned state, e.g. to carry a roller blind in order that it is parallel to the edges of a niche, are provided with oblong holes according to prior art, in order that the placement may be adjusted in connection with tightening of the screws use. According to the invention a larger capacity for adjustment may be obtained, in that washers ( 5, 9 ) with an oblong hole ( 3 ) are used, and in that the washes are rotatably fitted in holes ( 7 ) in the brackets.

1 . A bracket for mounting a sun screen, in particular in a niche, by means of screws or similar fastening devices, comprising at least one hole in the bracket and a washer fitted between the head of the fastening device and the bracket, characterized in that the hole ( 7 ) in the bracket ( 1 ) is circular, that the washer has a circular, plateau-shaped part ( 9 ) in a first plane, with a diameter equal to the diameter of the hole ( 7 ) and fitted rotatably in the hole ( 7 ), and a surrounding ring-shaped part ( 5 ) with a larger diameter in a second plane resting on the bracket ( 1 ), and in that the washer is provided with an oblong hole ( 3 ) in circular plateau part.  
   
   
       2 . A bracket according to  claim 1 , characterized in that the oblong hole ( 3 ) has a length that is equal to the diameter of the circular part ( 9 ).  
   
   
       3 . A bracket according to  claim 1 , characterized in that the ring-shaped part ( 5 ) has a serrated edge ( 11 ).  
   
   
       4 . A bracket according to  claim 1 , characterized in that the circular part ( 9 ) has projecting parts (p′) on that side of the element that is opposite the ring-shaped part ( 5 ), for holding the washer ( 5 ,  9 ) in the hole.  
   
   
       5 . A bracket according to  claim 1 , characterized in that there is established a click-adjustment ( 11 , p) of the angle of rotation of the washer.  
   
   
       6 . Use of a bracket according to  claim 1  in conjunction with at least two fastening devices comprising a head and a shank, characterized in that the circular parts ( 9 ;  10 ) of the washers are placed in the holes ( 7 ;  8 ) of the mounting bracket, that a fastening device is fitted through the oblong hole ( 3 ;  4 ) with clearance between the head and the washer, that the ring-shaped parts ( 5 ;  6 ) are rotated with respect to both fastening devices during alignment of the bracket ( 1 ) to its desired position, until the oblong holes ( 3 ;  4 ) permit free passage of the shanks of the fastening devices, whereupon the fastening devices art tightened in order to maintain the aligned position of the bracket ( 1 ).
