摘要： An apparatus for adjusting a tilt angle of a plurality of slats in a window blind. The window blind includes a headrail having disposed therein a shaft that rotates responsive to rotation of an externally accessible angle adjustment wand. The apparatus includes a pulley coupled with the shaft and the slats. The pulley causes adjustment of the tilt angle of the slats in response to rotation of the shaft, provides a first torque at a first position corresponding to an open position of the slats and a second torque at a second position corresponding to an approximately closed position of the slats, where the second torque is greater than the first torque.

摘要： An improved venetian type blind has slats each slat having at least two slots along one edge of the slats and one slot on the opposite edge of the slats. A slot on one edge is not opposite a slot on the other edge. Ladders having opposite cord type rails and rungs extending therebetween, are positioned so that one rail of a ladder is outside each of the slots and connected to the bottomrail. A lift cord passes through each of the slots between the slat and the ladder rail. A tilt mechanism attached to the headrail moves the rails of the ladders together when the blind is changed from an open to closed position.

摘要： An improved venetian blind having a head rail which carries an elongated rotator member. A first rotator band is connected to the rotator member and to the edges of a plurality of slats carried below the head rail. A second rotator band is connected to the rotator member such that pulling on one portion of the second rotator band causes the rotator member to rotate in one direction, which in turn causes the rotator band to tilt the slats in a first direction, and pulling on a second portion of the second rotator band causes a reverse rotation of the rotator member, to thereby cause the slats to be tilted in an opposite direction. The rotator band passes through a handle, and the handle includes a tilt member connected to the rotator band for allowing selectively tilting the slats through movement of the tilt member.
摘要翻译：一种改进的百叶窗具有头轨，其带有细长的旋转构件。第一旋转带连接到旋转体构件和承载在头轨下方的多个板条的边缘。第二旋转带连接到旋转体构件，使得拉动第二旋转体带的一部分使得旋转体构件沿一个方向旋转，这又导致旋转体沿第一方向倾斜板条，并且拉动第二旋转体带的第二部分导致旋转体构件的反向旋转，从而使板条沿相反方向倾斜。旋转带通过手柄，并且手柄包括连接到旋转带的倾斜构件，用于允许通过倾斜构件的移动选择性地倾斜板条。

摘要： A venetian type window blind having a wand which is rotatable to control tilting of slats and lift cord operating mechanism on the wand for raising and lowering the blind and locking the blind in adjusted positions. The venetian blind lift cords extend into a lengthwise cord passage inside the wand and the lift cord operating mechanism includes a lift member mounted for movement along an outer side of the wand and lift cord, an engaging member in the cord passage for moving the lift cords to raise and lower the blind in response to movement of the lift member along the wand. The operating means includes lock means for locking the lift cord engaging member at selected positions along the wand.

摘要： A window blind includes top and bottom beams, and many slats disposed therebetween. The top beam has two opposite lateral holes. The window blind further includes a slat folding transmission device having a cord rolling member disposed in the top beam, and two opposite lift transmission cords passing through the lateral holes of the lateral plates of the top beam respectively. Two ends of each lift transmission cord are connected with the bottom beam and the cord rolling member respectively, so that the two lift transmission cords can pull the bottom beam simultaneously when being rolled by the cord rolling member, thereby moving the bottom beam upwardly to fold up the slats. Therefore, the slats of the window blind of the invention need no processing and keep complete in structure, thereby providing good effect of blocking out the light when being adjusted to the inclined condition.
