the same or are very similar to that shown in fig1 b and which generally comprise a horizontally positioned rod 8 rotatably connected in and to head rail 12 multiple pulleys 5 affixed to rod 8 to spin with rod 8 with the pulleys 5 in spaced relationship with one another a worm gear wheel 16 is attached to rod 8 usually toward one end thereof a worm gear 15 is rotatably attached to head rail 12 and in contact with gear wheel 16 so that rotation of worm gear 15 causes rotation in worm gear wheel 16 which in turn rotates rod 8 and pulleys 5 trained over pulleys 5 are loops of string or cord 9 one loop per pulley 5 normally the loops of string 9 hang downward and include short horizontally disposed strings 3 connecting across the two sides of a given loop slats 13 rest atop horizontal strings 3 between multiple loops of string 9 the loops 9 trained over pulleys 5 are such that the string moves with the pulleys 5 when rotation occurs therefore strings 3 can be tilted and thus the slats 13 resting atop strings 3 may be tilted to varying degrees of open and to being vertically tilted to put the blind in a closed state normally slats 13 remain horizontal but tilt with the edge nearest the window rolling in a radius nearer or further relative to the window in typical venetian blinds the rod 4 is the device which the user grasps in hand to rotate the rod 4 and ultimately pulleys 5.
