ELECTRICALLY OPERABLE DRIVE ARRANGEMENT FOR VENETIAN BLINDS

摘要

The invention relates to an electrically operable drive arrangement for venetian blinds with at least one draw tape which tape is wound up or down by a motor located in the header. Switches in the header are operated by a feeler which moves respectively perpendicular to or parallel to the tape as the tape moves from its normal tangential position on the take-up roller upon bottoming of the blind, or when the blind reaches fully raised position.
