<p>TITLE: VERTICAL LOUVRE BLIND AND PARTS THEREFOR A vertical louvre blind has several identical travellers (16), an end one of which is moved by a pull cord (100), inserted between two fingers (90). This traveller pulls the other travellers by means of a ball chain (98) inserted between the fingers and into a slot (96). A tilt rod (14) rotates a worm (18) in each traveller, the worm engaging a wormwheel which can readily be pushed into the housing of the traveller. The wormwheel carries a hook (80) on which is mounted a louvre hanger. The louvre hangers each consist of two bars (30) and (34), the louvre material (22) being folded over to form a hem which can be clamped between the two bars by moving them transverse to their length. It is possible with the blind to have an easy modification of a stock blind to fit windows of several sizes.</p> |
