Abstract: A buffer apparatus for rolling curtain. The buffer apparatus is disposed in a reel of the rolling curtain, including a housing, a clutch mechanism disposed in the housing and movable between an adjoining position and a separated position and a driving shaft fitted in the housing and drivingly connected with the clutch mechanism. One end of the driving shaft protrudes from the housing to connect with a rotary disc. The rotary disc is drivable by the reel to drive and rotate the driving shaft and operate the clutch mechanism. When the reel forward rotates to drop the drape of the curtain, the clutch mechanism is moved from the adjoining position to the separated position and no damping effect is created. When the reel backward rotates to wind the drape and a certain length of the drape remains, the clutch mechanism is moved from the separated position to the adjoining position.

Abstract: Roller curtain with back rolling force, including: two end members; a locating mechanism connected with a first end member; a hollow reel positioned between the two end members with one end fitted on the locating mechanism, whereby the reel is drivingly rotatable by the locating mechanism for winding or unwinding the curtain; a fluid pressure cylinder in which the piston stem keeps outward extending in normal state, the pressure cylinder being fitted in the reel with the rear end connected with the second end member, the other end of the reel being rotatably fitted with the cylinder body; and a linking device disposed between the reel and the pressure cylinder for converting the rotational movement of the reel into linear movement of the piston stem. When the reel rotates to unwind the curtain, the linking device retracts the piston stem into the cylinder body to reserve a pressure source in the pressure cylinder.

Abstract: A window blind, which includes a track; a blind suspended from the track; a plurality of blind take-up mechanisms respectively mounted inside the track, each blind take-up mechanism including a spool holder securely mounted inside the track, a spool revolvably supported on the spool holder, at least one positioning element detachably fastened to the spool, and a lift cord having a top end fastened to one positioning element at the spool and a bottom end fastened to the blind for enabling the blind to be taken up/let off upon rotary motion of the spool; and a control unit securely mounted on the track at one end for operation by hand to rotate the spools of the blind take-up mechanisms through a transmission rod thereof, for enabling the blind to be lifted or lowered.

Abstract: A lifting track of curtain is composed of a track, a plurality of winding mechanisms each having a carrying seat, a cord-winding shaft, and a cord fastened at one end thereof with the cord-winding shaft and at another end thereof with the curtain. As the cord-winding shaft is turned, the cord is wound on the cord-winding shaft such that the cord slides from a large diametrical end of a cylindrical body of the cord-winding shaft toward a small diametrical end of the cylindrical body of the cord-winding shaft. The carrying seat is provided with a concave surface for preventing the intertwining of the cord at the time when the cord is wound on the cord-winding shaft.
