SYSTEM FOR COUPLING ROLLER SHADE TUBES

摘要

A coupling assembly for a multiple-tube roller shade includes a support assembly for rotatably supporting and connecting adjacently located tube-end portions and a clutch mechanism providing relative rotation therebetween. The support assembly includes a tube­end fitting and a torque-transferring drive transfer member contacting the tube. The clutch mechanism includes first and second clutch members respectively engaged and separated in closed and opened positions. A pull bar is translatable within one of the shafts and is moved by a draw pin received in aligned openings of the second clutch member, the shaft and the pull bar. The shaft openings are elongated for movement of the second clutch member between the closed and opened positions. An adjustment member threadedly engages the tube-end fitting for vertical adjustment of the fitting with respect to a support panel. The tube-end fitting is secured to a bracket having elongated openings for horizontal adjustment.
