ABSTRACT:
A semi-automatic shutter slat orientation adjustment and drape release control as applied in double-layer window drape compatible with Venetian blind slat; in more specific terms a composite structure of a blind, be it vertical or horizontal in execution, with a drape in a common tringle or top rail confined in a double rail guide, so that it makes possible switching selection of frontal or rear settings by means of a pair of opposing bevel gears with a single sliding sleeve that is driven by a ball chain carried in a support wheel. Under normal conditions, the sleeve, once acted upon by a compression spring behind it, will bring the frontal side of a composite bevel gear into engagement with the transmission bevel gear for the drape roller, thereby achieving release control of the drape sections, whilst orientation adjustment of the Venetian blind is performed by withdrawing the sleeve with the ball chain, to result in bringing the composite bevel gear into engagement with a transmission bevel gear provided on the orientation adjustment shaft for the Venetian blind.
