APPARATUS FOR ASSEMBLING LOUVRED BLINDS:GUIDE MEMBER ACTUABLE BY LIFTING LADDER COMPRISES FLAP PIVOTABLE ON HORIZONTAL AXIS

摘要

The invention relates to an apparatus for assembling the louvres of louvred blinds to the supporting ladders and elevating members and includes a vertically disposed flap pivoted at its bottom and having a ladder guide along one face. A louvre is inserted horizontally between the two vertical stringers and between two adjacent rungs thereof. The flap lying to one side holds the ladder obliquely such that the rung above the louvre is to one side of a hole therethrough. The louvre is then lifted and a vertical needle for inserting an elevating member such as a cord or chain enters the hole as the louvre is lifted. This lifting motion also lifts the ladder which motion causes the flap to pivot and flip to a position on the other side of the hole so that the next successive rung will be on the other side of the hole and the needle. The assembly continues and results in the rungs of the ladder being disposed alternately on opposite sides of the elevating member.
