摘要： A cellular shade includes a head rail unit, an intermediate rail unit, a bottom rail unit, a blind body and a magnetically attractive unit. The head rail unit includes a head rail and a lower mounting bracket. The intermediate rail unit includes an intermediate rail and an upper mounting bracket. The magnetically attractive unit includes a first housing mounted on the lower mounting bracket, a second housing mounted on the upper mounting bracket, and a magnet mounted on one of the first and second housings. The other one of the first and second housings is magnetically attractive with the magnet. The first housing includes a first positioning member to be retainingly positioned to the lower mounting bracket. The head rail unit and the intermediate rail unit can be firmly secured to each other by means of the magnetically attractive unit so as to prevent light leaking.

摘要： A venetian blind includes a frame unit, a slat unit, a transmission unit, and an operating unit. The slat unit includes multiple drive axles and a plurality of slats each connected co-rotatably to the drive axles. The transmission unit includes two transmission rollers, a plurality of constant-force coil springs that are linked together and that are coupled to the drive axles, and a belt that cooperates with the constant-force coil springs to form a loop trained on the transmission rollers. The operating unit includes an inner control member connected to the belt, and an outer control member operable to drive the inner control member to move so as to drive rotation of the drive axles via the constant-force coil springs to rotate the slats.

摘要： A driving device is for a window blind. The driving device includes a mounting frame disposed between parallel first and second plates of the window blind, and first and second transmission members. The first transmission member has an inner magnetic portion and a worm portion. The inner magnetic portion is adapted to be disposed adjacent to the first plate, and is rotatable under influence of a magnetic force from a side of the first plate. The worm portion is co-rotatably connected to the inner magnetic portion. The second transmission member has a worm gear portion meshing with the worm portion, and a driving rod connected to the window blind so as to be driven rotatably by the first transmission member to operate the window blind.

摘要： A driving device includes amounting frame, a driving rod, a driving gear, a worm, primary and auxiliary input members, and a reduction gear train. The mounting frame is connected to a frame unit. The driving rod is connected to a blind unit and is rotatable about a first axis. The driving gear is connected to the driving rod. The primary input member is rotatable about a second axis. The worm is connected to the primary input member and meshes with the driving gear. The auxiliary input member is rotatable about the second axis. The reduction gear train is connected between the primary and auxiliary input members, such that rotation of the auxiliary input member drives the primary input member to rotate at a speed different from that of the auxiliary input member.

摘要： A cord-winding device for a Venetian blind includes: a first reel; a driving unit including a driving wheel and a spring-winding wheel; and a brake unit including a driven gear, a driving member, a ratchet wheel sleeved on the driving member, a plurality of friction members disposed between the driving member and the ratchet wheel, and at least pawl biased to engage the ratchet wheel. When the driven gear is driven by the first reel to rotate in a direction, rotation of the ratchet wheel is stopped by the pawl so that the driving member drives the friction members to rotate, and when the driven gear is driven by the driving wheel to rotate in an opposite direction, the driving member drives rotation of the friction members and, thus, the ratchet wheel.

摘要： A driving device for a window blind includes a rotary unit and a driving unit . The rotary unit includes a rotary shaft and a screw nut. The rotary shaft is mounted in a receiving space of a lower rail, is rotatable relative to the lower rail about an extending axis thereof, and is configured to permit pull cords to be wound thereon, such that rotation of the rotary shaft drives the lower rail to move relative to an upper rail. The screw nut engages a threaded section of the rotary shaft and is fixedly connected to the lower rail, such that the rotary shaft moves along the extending axis relative to the lower rail upon the rotation thereof relative to the lower rail. The driving unit is linked to the rotary shaft for driving the rotation of the rotary shaft.
