1. A length adjustable fitting for blind systems, comprising:
a housing and a drive member fitted to said housing; and a core component including a core member shaped for engaging a drive portion of said drive member, the core component including a support portion shaped for engaging a support member for supporting said fitting; wherein: the selective adjustment of the drive member relative to the housing drives movement of the core member along an axis to a different position relative to the housing, wherein at each said position, the drive member engages the core member to resist movement of the core member along the axis from said position relative to said housing; wherein the drive member is rotatable relative to said housing in a length extending direction wherein it drives the core component from a retracted position towards an extended position where a portion of said core component is positioned outside of said housing; and wherein the drive member is also rotatable relative to said housing in a length retracting direction opposite to the length extending direction; and wherein the core component is operable according or both of options (i) and (ii) below: i) when the core component is placed in the extended position:
rotation of the drive member in the length extending direction moves the core component towards the retracted position; androtation of the drive member in the length retracting direction causes the drive member and the core component to engage so as to resist movement of the core component towards the retracted position; and ii) when the core component is placed in the retracted position:
rotation of the drive member in the length extending direction moves the core component towards the extended position; androtation of the drive member in the length retracting direction causes the drive member and the core component to engage so as to resist movement of the core component towards the retracted position.
