摘要： Abstract A blind with a looped blind sheet for adjusting opacity is revealed. The blind includes a top rod 5 supporter, a top rod with two ends connected to the top rod supporter, a bottom rod supporter, a bottom rod with two ends connected to the bottom rod supporter, and looped blind sheet. The looped blind sheet with predetermined length and width includes 10 alternate see-through parts and opaque parts and connected to form a loop having a front blind sheet and a rear blind sheet wound between the top rod and the bottom rod. When the front blind sheet or the rear blind sheet is pulled down or up, the 15 opacity is adjusted by overlap degree of the see through parts and the opaque parts of the front and the rear blind sheets changing without changing the length of the looped blind sheet. 2722062_1 (GHMatters) P87486.AU 30/06/11 09---207 141b -203

摘要： The Venetian blind for a building window has involves lengthening the upper vertical pull cord section of the running cord of the blind (51) which is provided in a conventional blind for adjusting the louvre angles. The lengthened cord section remains movable and attached to the rotor for adjusting the louvre angle. The cord is then run over a spool. The upper section of the louvres can be lowered by rotation of the spool to leave a clear upper gap at the top of the louvres.

摘要： A Venetian blind includes a tilt means having multiple ladder strings for tilting slats of the blind connected to the ladder strings. Each of the ladder strings includes a front and a rear vertical strings, and a plurality of transverse ladders spaced between and along the front and the rear vertical strings. Upper ends of the two vertical strings are upward extended to provide a front and a rear hanging section, respectively, without any transverse ladders spaced between the hanging sections. Upper ends of the hanging sections are upward and movably extended through a tiller and then wound around a reel fixedly mounted on a rotary shaft in the head rail of the Venetian blind. The two hanging sections may be synchronously released from the reels when the rotary shaft is turned forward, so that the upper slats are lowered to a distance below the head rail of the blind, and a light transmissible area without being shielded by any slat is provided above the upper slats, and the lowered slats could still be deployed and tilted to adjust volume and direction of light projected through the blind.
