Abstract

A drape or blind assembly having a headrail in which there is disposed a shaft, on rotation of which the position of the drapes or blind slats is adjusted, and a transmission mechanism which comprises a drive gear and a coupling adapted to be coupled to such a shaft so that rotation of the drive gear normally causes rotation of the shaft. If, however, the drive gear is rotated past a predetermined rotational position, a stop member generally provided on the coupling engages an abutment member to prevent further rotation of the shaft. To prevent damage to the mechanism in such a situation, the mechanism includes a recess defined by first drive surfaces and a resilient arm means having Complementary second drive surfaces. On continued rotation of the drive gear after the stop member has engaged the abutment member, the resilient arm means flexes to permit relative rotation of the first and second drive surfaces. Bearings are provided in the headrail far rotatably supporting the shaft, and retaining it in position.
