Adjustment Element

Abstract

The present invention relates to an adjustment element for local adjustment of the circumference of a blind roller for a roller blind, said blind roller having a first end, and a second end between which the blind is wound, a blind roller surface, and an axis of rotation extending axially in relation to said blind roller, said adjusting element comprising an adjustment means adapted to be mounted in proximity to one of said ends and adapted to be displaced relatively to said blind roller surface. In accordance with the invention an adjustment member is configured to partly encircle the circumference of said blind roller and adapted to cooperate with said adjustment means in a way that said adjustment member upon activation of said adjustment means locally is displaced from said surface of said blind roller to thereby adjust said circumference.

1 . An adjustment element for local adjustment of the circumference of a blind roller for a roller blind, said blind roller having a first end, and a second end between which the blind is wound, a blind roller surface, and an axis of rotation extending axially in relation to said blind roller, said adjusting element comprising an adjustment means adapted to be mounted in proximity to one of said ends and adapted to be displaced relatively to said blind roller surface, characterized in that said adjustment element further comprises an adjustment member configured to partly encircle said blind roller to form together with said surface a circumference on which said blind is wound, and adapted to cooperate with said adjustment means in a way that said adjustment member upon activation of said adjustment means locally is displaced in relation to said surface of said blind roller to thereby adjust said circumference. 
   
   
       2 . An adjustment element according to  claim 1 , wherein a recess extending axially, preferably in the full length of said blind roller. 
   
   
       3 . An adjustment element according to  claim 2 , wherein said adjustment means including a circular threaded part, and in that a block is configured to be arranged in said recess, said block comprising a top surface and a tapped hole configured to cooperate with said circular threaded part, wherein said top surface is configured for abutment with an under side of said adjustment member, and a base portion of said threaded part is configured to cooperate with a bottom surface of said recess. 
   
   
       4 . An adjustment element according to  claim 3 , wherein said block comprises lateral side surfaces that when mounted in the recess abut against inwardly protruding lips to thereby provide guidance for the block and prevent rotation of the block upon operation of the threaded part. 
   
   
       5 . An adjustment element according to  claim 1 , wherein said adjustment member is essentially tubular in shape and comprises a first lateral edge and a second lateral edge extending in a direction along said blind roller when mounted; a first edge and a second edge arranged opposite to each other and extending transversely to said blind roller when mounted, wherein at least one aperture is configured centrally in proximity to at least one of said first or second edges. 
   
   
       6 . An adjustment element according to  claim 1 , wherein said adjustment member is configured of a resilient sheet material, preferably metal or plastics. 
   
   
       7 . An adjustment element according to  claim 1 , wherein said adjustment member is adapted to cover said block, and that said aperture in said adjustment member allows access to said threaded part to thereby enable the operation thereof. 
   
   
       8 . An adjustment element according to  claim 1 , wherein said threaded part is configured with means for cooperating with an Allen key. 
   
   
       9 . A blind roller for a roller blind wherein at least one adjustment element according to  claim 1  is adapted on said blind roller.
