Abstract: The blind includes an upper beam, a rope winder and a lifting rope. The bottom wall of the upper beam includes a through hole for the lifting rope to penetrate therethrough. The rope winder is arranged inside the upper beam and includes a top plate and a bottom plate. A winding wheel for winding the lifting rope is arranged between the top and bottom plates. The stringing apparatus of the present invention is arranged on the bottom wall of the upper beam and protrudes out of the top surface of the bottom wall. The relationship between a vertical distance from the bottom surface of the top plate of the rope winder to the top surface of the rope winder and a distance from the top surface of the stringing apparatus to the top surface of the bottom wall of the upper beam satisfies the relation of 2-5:1.

Abstract: A blind capable of stepless positioning includes a control unit which controls the positioning of a shade, is disposed in a roller, and has a fixed sleeve, a spindle, a movable sleeve and a pre-torque spring. The fixed sleeve is fixedly disposed at a roller holder and fitted around one end of the spindle, whereas the movable sleeve is fixedly disposed at the roller and fitted around the other end of the spindle; hence, the movable sleeve rotates together with the roller. The pre-torque spring is fitted around the spindle and has two ends connected to the fixed sleeve and the movable sleeve, respectively, such that the pre-torque spring operates in conjunction with the movable sleeve. While the shade is being rolled up and rolled down, a predetermined torque level of the pre-torque spring matches the length of the shade to therefore brake the shade at any height.

Abstract: A Roman shade includes a shade having multiple folded sections formed thereon and multiple control units are connected to the folded sections. Each control unit includes a connection unit and a rope unit. The connection unit and the rope unit share a common end. The connection unit is sewed to the folded sections so as to allow the transmission rope in the connection unit to move freely within the connection unit. The distance between the connection ropes of the rope unit restricts the transmission rope from being pulled out easily.

The transmission ropes are operated steadily and effectively.

Abstract: A hollow slat includes an elongate body having a space defined therein and two ends of the elongate body are two closed ends. At least two through holes are defined through top and bottom surfaces of the elongate body and each through hole has a peripheral wall which is connected between the top and bottom surfaces of the elongate body such that the through holes are not in communication with the space in the elongate body.

Abstract: A Roman shade includes a top box and a shade including a first layer and a second layer is connected to the top box. The first layer includes multiple pocket portions formed thereon and the pocket portions each are defined by folding a part upward to define a passage which extends transversely through the first layer. Multiple first holes and second holes are defined through the first layer. The pocket portion is located between the first and second holes. The second layer is located on a first side of the first layer and two control ropes each have a top end connected to the top box and a lower end of each control rope extends through the first hole from the first side of the first layer and passes over a second side of the first layer and then extends through the second hole in sequence.

Abstract: A control device for blinds includes a transmission unit, a scrolling unit and a tilting unit, the transmission unit includes a case in which a coil spring and a gear unit are received. The coil spring is connected between the gear unit and the case. The scrolling unit includes two scrolling rods which are rotated with a transmission rod. Each scrolling rod has a lift cord wrapped thereon and extending through slats of the blinds. The tilting unit includes two tilt members connected to two respective end sections of the two scrolling rods. Two tilt cords have two respective positioning members which are clamped in two clamp grooves of the two tilt members and the tilt cords extend through the slats. The gears in the gear unit can be adjusted so as to cooperate with slats of different weights.

Abstract: A slats control system for blinds includes a first control rope and a second control rope. Two respective first ends of the two control ropes are fixed to the control members corresponding thereto and the axis of the control member is located between the first control rope and the second control rope. Multiple odd-numbered slats and even-numbered slats are connected to the head box. Multiple connection ropes extend through the slats and are connected between the head box and a bottom bar. A first/second driving rope is transversely connected to an underside of the odd-numbered slat/even-numbered slat. The first/second control ropes are connected to the first/second driving ropes on each slat. When the control members are rotated by rotating a shaft, the first/second control rope and the second/first control rope are lifted and the lowered simultaneously. The odd-numbered slats and the even-numbered slats are rotated in opposite directions simultaneously.

Abstract: A operation wand assembly of a curtain a curved connection member adapted to be connected to the lower rail of the curtain and having a top recess.
