Abstract:
1. A multiple element blind assembly connector which connects at least a first blind tube around which a first blind may be wound to a second blind tube around which a second blind may be wound, the connector comprising: a first coupling element attachable to the first blind tube, said first coupling element having a body and a projection extending therefrom, said projection including a first keying portion having a first interference region; a second coupling element attachable to the second blind tube, said second coupling element having a body defining a bore therein, which includes a second keying portion having a second interference region; wherein said first keying portion is insertable into said second keying portion along an insertion axis and upon insertion said first interference region keys with the second interference region of said second keying portion to a torque transferring position such that torque applied to one of said coupling elements is transferred to the other coupling element by interference between one interference region acting on the other interference region, and wherein said first keying portion is only insertable into said second keying portion to said torque transferring position when said first and second coupling elements are aligned within a single relative rotational range along said insertion axis; and wherein said first keying portion is capable of being inserted into and keyed with said second keying portion concurrently with either or both of said blind tubes substantially wound around by their respective blinds.
