Abstract
A connection system between a carrier and a link of a pantograph in a control system of a covering for an architectural opening. The control system is adapted to move a plurality of carriers across at least a portion of the architectural opening. The connection system comprises an upstanding pin on the carrier, the pin having a laterally projecting key, and an aperture in the link. The aperture has a main portion extending upwardly from a bottom surface of the link and an enlarged recess extending downwardly from a top surface of the link, thereby defining an annular shoulder around the top of the main portion. An intermediate keyway communicates between the main portion of the aperture and the enlarged recess. The keyway is adapted to receive the key on the carrier to facilitate interconnection of the carrier with the link and pivotal movement of the carrier relative to the link after interconnection.
