Abstract
A venetian blind (10) having a low profile headrail (18) is provided particularly useful for double-glazed and/or screened windows. A tilt mechanism (24) extends horizontally and outwardly from one end of the headrail and includes internal drive gearing and a spocket moving a horizontal beaded chain (31) held in a pair of clamping blocks (33) slidably movable to and fro in a guide channel (32) in the headrail. A tilt wand connector includes upper legs insertable into a square bore in a drive gear. The clamping blocks include clamp levers (34) for clamping the upper ends (20c) of vertical legs (20a) of the tape ladders supporting the blind slats (17) so that the orbital motion of the chain and sliding motion of the clamping blocks pulls or slackens opposite legs (20a, 20b) of the ladders effecting tilting of the blind slats. A draw cord and mounting screw guide (36) is included in the headrail which minimizes or prevents fraying of the draw cord(s) 21a. A combined chain tensioner (60) and cord lock assembly (40) is provided in an end casing (63) insertable into the other end of the headrail.
