facing that occurs when the vanes are in a substantially horizontal position e g perpendicular to the facings for maximum transparency as a result a user can pull the outer back bottom weighted rail downward past the normal maximum condition i e vanes substantially horizontal maximum transparency with another downward pull to set or release the ratchet in the roller a view through substantially transparent position can be achieved comfortably with the shade extending through exactly the full length of the corresponding window height the ratchet can also include stops spaced no farther apart than the roller rotation angle associated with an over draw length to enable an over pulling motion to set or release the ratchet the spacing of stops can also vary depending on the width of the vanes and the diameter of the roller in a particular embodiment the ratchet can include multiple stops within a single complete rotation thereby allowing the vanes to be set at intermediate angles between fully open i e substantially transparent and shut i e an opaque setting which approximates a flattened fabric as shown in fig1 a window shade assembly 100 according to embodiments of the present disclosure is shown window shade assembly 100 may be embodied as a fabric venetian window shade a venetian window shade refers to a window shade composed of several horizontal shade bars as examples window shade assembly 100 can include one or more.
