ABSTRACT:
A wand for adjusting window blinds comprises at least two wand sections. The first wand section is an elongated rod having a hook at one end for attachment to a mechanism for adjusting a window blind. A connection means comprising four longitudinally extending lobes is arranged at the other end of the first wand section. A second wand section comprises also an elongated rod having four fingers at one end thereof designed such that the fingers interengage between the four lobes of the first wand section to releasably and non-pivotably interconnect the two wand sections. Small teeth located on the sides of the fingers engage in notches formed in the lobes to maintain the two wand sections in engagement. Additional wand sections, similar to the second wand section, can be added to the second wand section to further lengthen the blind adjusting wand.
