[Prior art] The Venetian blinds have-an upper guide and-a τ guide. The upper guide is connected to the upper part of the money seems to be fixed. The hoisting rope of the lifting mechanism of the unloading rod is suspended below the upper guide rod. The horizontal slats ride between the upper guide and the τ guide. By tilting the inclination of the horizontal slats, the amount of light passing through the window can be adjusted. If necessary, the Venetian blinds can also be raised to allow light to pass through the window. In order to raise the blinds, the user can simply pull one rope or several ropes tied together. The lower end guide can be raised by pulling a rope towards the upper end guide. When the lower guides contact each slat, the 7jc slat is concentrated on the lower guides, thereby opening the shutters. One problem with Venetian blinds is that the weight of the shutter components (ie, the lower end guides and concentrated slats) makes it difficult to lift. This problem is particularly acute for wooden Venetian blinds weighing more than 10 kg. Therefore, there is a need for a system that provides a method for users to easily operate Venetian blinds. [Summary of the Invention] According to the present invention, it provides a Venetian blind, which has an upper end guide, a lower end guide and a horizontal slats located between the upper and lower end guides, one for adjusting the Venetian blind. 86254 -6-200406531 mechanism of the height of the lower guide rod; wherein the pulling mechanism includes: a first member attached to the upper guide rod, a second member attached to the lower guide rod, and-a rope 'It is attached to one end of the Venetian blinds and passes around the first member and the second member, wherein the displacement of the free end of the rope is greater than the displacement of the lower guide rod in order to adjust the lower guide rod using mechanical gain. height. The brother-member and the second member can be any element that allows the rope to pass without excessive frictional resistance. The rope is preferably connected to the upper guide bar of the shutter member. A better way is to attach the tether near the first member connected to the upper guide. The first member may optionally be one of a plurality of similar members connected to the upper guide, and the rope passes through the member connected to the upper guide. In the further < selection, the second member may be any one of a plurality of similar members connected to the lower end guide, and the rope is wound around the member connected to the lower end guide. The component is preferably a rotatable component. It can therefore rotate as the rope passes over it. The component is better with a pulley. Preferably, the Venetian blinds may have at least two lifting mechanisms. Preferably, the Venetian blind has another rope member for receiving the lifting mechanism. Preferably, the other member is a rotatable member. The member is therefore rotatable when the rope is passed over it. The component is more effective as a pulley. [Embodiment] 86254 200406531 FIG. 1 depicts a traditional Venetian blind assembly 150, which has an upper guide m and a lower guide 12, a horizontal slat 135, a rope bundle 125, and a lifting mechanism 130, 131. . The pulling mechanisms 130 and 131 are provided with pulleys m and 113 and pulling ropes 160 and 161 connected to the lower guide bar 120. The pull ropes 16 and 161 pass through the second pulley 15 and form a rope bundle 125. In the lifting mechanism 130, 131 of the shutter assembly 150, the displacement of the rope bundle 125 is converted into the same displacement of the lower end guide 12o. FIG. 2 illustrates the shutter assembly 50 with the lower guide 20 in the lowest position. The upper end guide 21 of the louver assembly 50 is connected to a window (not shown). The horizontal strip 35 is distributed between the lower guide 20 and the upper guide 21. By changing the length of the rope bundle 25, the position of the lower guide 20 can be adjusted, and therefore the position of the shutter assembly 50 can be adjusted. Figure 3 depicts the blind assembly 50 when partially opened in Figure 2, with the lower end guide 20 located between the highest position and the lowest position. After raising the lower end guide 20, the slats 35 are continuously concentrated on the lower end guide 20. Therefore, the slats are lifted together with the lower guide 20. The rope bundle 25 is composed of pulling ropes corresponding to the lifting mechanisms 30 and 31, respectively. The pull ropes 1 and 2 are connected to the upper guide rod 21 at the attachment points 5 and 6. The attachment points 5 and 6 are respectively located near the corresponding main pulleys η and π. Starting from attachment point 5, the pull rope 1 first loops through the lower main pulley 10 fixed to the lower guide 20, and then the pull rope 1 loops through the higher main pulley 11 fixed to the upper guide 21 similar Ground, starting from attachment point 6, the pull rope 2 first loops through the lower main pulley 12 fixed on the lower guide 20, and then the pull rope 2 loops through the lower fixed pulley 12 fixed on the upper 86254 -8-200406531 The high main pulley 13, the pull ropes 1 and 2 then all pass through the second pulley 15 at the forming rope bundle 25. Between the attachment points 5, 6 and the lower main pulleys 10, 12, and between the lower main beta wheels 10, 12 and the higher main pulleys 11, 13, the pull ropes 1, 2 are usually oriented vertically. Therefore, the lower guide bar 20 is suspended downward at the self-attachment points 5, 6 and the higher main pulleys 11, 13. The suspended mass of the concentrated slat and the lower end guide 20 is supported by four suspension points (attachment points 5, 6 and higher main pulleys u, 13). The pull ropes 丨, 2 transfer the gravity of the hanging mass applied to the respective higher main pulleys 11, 13 to the second pulley 15, and finally to the rope bundle 25. When the gravity of the suspension mass is evenly distributed between the suspension points, the force required to load the blinds by the rope bundle 25 is half of the gravity of the suspension mass. The displacement of the rope bundle is greater than the displacement of the lower guide 20. Therefore, a mechanical gain is obtained when the lower guide 20 is lifted. Figure 4 shows a shutter assembly 50 with a two-lift mechanism. The upper guide bar 21 is provided with relatively main pulleys π and π, and the attachment points 5 and 6 of the pull ropes 1 and 2 are also provided thereon. The second pulley 15 is connected near the upper guide rod end 21 so that the user can operate the rope bundle 25 away from the lifting mechanism. Those skilled in the art can easily modify it within the scope of the present invention. Therefore, I should understand that the present invention is not limited to the specific embodiments described above by way of example.
