Abstract
1509947 Venetian blinds LEVOLOR LORENTZEN Inc 12 Sept 1975 [30 Sept 1974] 37548/75 Heading E1J A venetian blind has a tilt mechanism with a gear 42 in the form of a sector of less than 360‹, which gear runs out of mesh with a drive worm 41 after the blind has been closed to a maximum. The gear may then retrogress and re-engage the worm. The retrogression may be up to the maximum closure position or slightly beyond it in which case slight opening of the slats occurs. The worm is operated manually by a rod 45. The gear is mounted on a tilt rod 24 carrying drums on which the ladders 18 are wound.
