The structure is shown in Figures 2 to 5. The upper light-adjusting curtain body 40 is assembled between the upper rail 10 and the middle rail 20, and the lower light-adjusting curtain body 50 is assembled between the middle rail 20 and the lower rail 30.

According to this, when the first rope puller 15 drives the first rope reel 11 to retract or release the first rope body 13, the upper dimming curtain body 40 can be driven to be folded or unfolded. In addition, when the second rope puller 16 drives the second rope reel 12 to retract or release the second rope body 14, the lower dimming curtain body 50 can be driven to be folded or unfolded.

To further explain, the upper light-adjusting curtain body 40 and the lower light-adjusting curtain body 50 have different use effects, and can be selected as a light-transmitting curtain or a light-blocking curtain respectively. In this embodiment, the upper light-adjusting curtain body 40 is set as a light-transmitting curtain, and the lower light-adjusting curtain body 50 is set as a light-blocking curtain. The above is only one embodiment of this invention and should not be limited to this. The upper and lower light-adjusting curtain bodies 40 and 50 can not only be replaced with light-transmitting curtains or light-blocking curtains, but can also be set as curtains with effects other than light-transmitting and light-blocking according to special needs.

For further explanation, please refer to Figures 6 and 7 to see that the lower dimming curtain body 50 can further surround and wrap around the outer circumference of the lower rail 30.

The actual use of the structure is shown in Figures 1, 5, and 8. In this embodiment, the upper and lower light curtain bodies 40 and 50 are respectively received by the first and second rope reels 11 and 12 to reel in the first and second rope bodies 13 and 14 to rise to form a fully light-transmitting state. At this time, the first rope body 13 pulls the middle rail 20 to move upward and pushes the upper horizontal rail 41 to rise. The upper dimming curtains between the upper horizontal rails 41 fall and overlap toward the opening 4111 of the embedded tube 411, and the second rope 14 pulls the bottommost lower horizontal rail 51 to move upward, and pushes the lower horizontal rails 51 to rise and fit together, so that the lower dimming curtains 50 between the lower horizontal rails 51 fall and overlap toward the opening 5111 of the embedded tube 511.

Next, as shown in Figures 9 to 11, the lower dimming curtain body 50 of this embodiment is unfolded. The second rope puller 16 drives the second rope reel 12 to operate and release the second rope body 14. At this time, the lower rail 30 moves downward due to its own vertical weight, and pulls down the lower horizontal rail 51 in sequence, so that the lower dimming curtain body 50 is gradually unfolded downward from the middle rail 20. Since the lower dimming curtain body 50 is a blackout curtain, it further blocks external light to form a blackout state.

As shown in FIGS. 12 to 14, the upper dimming curtain body 40 is unfolded according to the present embodiment. The first rope puller 15 drives the first rope reel 11 to operate and release the first rope body 13. At this time, the middle rail 20 moves downward along the second rope body 14 due to its own vertical weight, and pulls down the upper horizontal rail 41 in sequence, thereby moving the upper dimming curtain body 40 from the upper The rail 10 gradually unfolds downwards. Since the upper light-adjusting curtain body 40 is a light-transmitting curtain, it further allows external light to penetrate into the light-transmitting state, and at the same time, the curtain body is used to achieve the indoor privacy effect. When the upper light-adjusting curtain body 40 moves downwards and unfolds, the middle rail 20 moves downwards along the second rope body 14 and pushes the lower horizontal rail 51 downwards in sequence, thereby folding the lower light-adjusting curtain body 50 downwards.

In addition, since the upper dimming curtain body 40 is unfolded downward, the lower dimming curtain body 50 is simultaneously retracted downward, and the light transmission range is adjusted by the unfolding degree of the upper dimming curtain body 40, so as to have a semi-shielding and semi-transmitting effect.

Continuing from FIG. 8, it is a schematic diagram of the present embodiment in which the upper and lower dimming curtain bodies 40, 50 are both folded upwards. In the general design, since the first and second reels 11, 12 are not linked to form a state of separate control, the dimming Roman curtain in the state of FIG. 1 is directly controlled by the second pull cord 16. When the second rope 14 is retracted by the middle rail 20, the upper dimming curtain 40 is pushed by the middle rail 20 to move toward the upper rail 10 for retraction, but the first rope 13 is not retracted and thus becomes loose, so that the first rope 13 is easily entangled and knotted. Therefore, when the upper and lower dimming curtains 40 and 50 are both retracted upward to form a dimming curtain, the first rope 13 is not retracted and becomes loose. When the Roman blind is in the fully light-transmitting state, the first pull rope device 15 must first control the first reel 11 to roll up the first rope body 13, thereby driving the middle rail 20 to move upward and push all the upper horizontal rails 41 toward the upper rail 10 to achieve the purpose of folding the upper dimming curtain body 40. At this time, the lower dimming curtain body 50 is in the unfolded state. Then, the second pull rope device 16 controls the second reel 12 to roll up the second rope body 14, thereby driving the bottommost lower horizontal rail 51 to move upward and push all the lower horizontal rails 51 toward the middle rail 20 in sequence, thereby achieving the state of the upper and lower dimming curtain bodies 40 and 50 being fully folded.

Another embodiment of the invention is shown in FIG. 15. A linkage device 18 and a clutch device 19 may be provided inside the upper rail 10. The linkage device 18 is installed and connected between the first reel 11 and the second reel 12, so that the first and second reels 11 and 12 can achieve synchronous reeling action through the linkage device 18. The clutch device 19 is installed on the first pull rope 15, so that the first pull rope 15 and the first reel 11 have a clutch effect. Accordingly, when the first pull rope 15 is actuated and controlled, the clutch device 19 forms a coupling state, so that the first pull rope 15 can be controlled. The first reel 11 is controlled to retract, while the second reel 12 is synchronously linked to the first reel 11 through the linkage device 18. The clutch device 19 will be disengaged, so that the first reel 11 cannot drive the first pull rope 15 to operate, thereby avoiding the first pull rope 15 from being damaged and achieving a foolproof protection effect. Furthermore, when the upper dimming curtain body 40 is in an unfolded state, the user can directly control the first and second reels 11 and 12 to retract the first and second rope bodies 13 and 14 through the second pull rope 16 to achieve a fully retracted state of the upper and lower dimming curtain bodies 40 and 50.

The structure of the above-mentioned specific embodiment can achieve the following benefits: the Roman blind of the invention has an upper dimming curtain body 40 and a lower dimming curtain body 50 with different dimming effects. The upper dimming curtain body 40 is assembled between the upper rail 10 and the middle rail 20, and the lower dimming curtain body 50 is assembled between the middle rail 20 and the lower rail 30. The folding and unfolding actions of the upper and lower dimming curtain bodies 40 and 50 are achieved through the first and second winding rope devices 11 and 12, so that the Roman blind has a two-stage operation control effect, thereby providing users with the ability to adjust the amount of light penetration while taking into account the indoor privacy effect, greatly improving the practicality of the Roman blind, and thus increasing consumers' willingness to purchase.

In summary, this creation has indeed achieved a breakthrough structural design, and has improved new content, while also being able to achieve industrial applicability and progress. Moreover, this creation has not been seen in any publication and is also novel, so it should comply with the relevant provisions of the Patent Law. Therefore, we have filed a new patent application in accordance with the law and pleaded with the Jun Bureau Review Committee to grant legal patent rights. We are very grateful.

However, the above is only a preferred embodiment of this invention, and it cannot be used to limit the scope of implementation of this invention; that is, all equivalent changes and modifications made according to the scope of this new patent application should still fall within the scope of this new patent.
