To further explain, a connecting groove 23 is provided at the lower end of the middle rail 20, and the top end of the Roman curtain body 40 is embedded and fixed in the connecting groove 23.

To further explain, as shown in FIGS. 5 and 6, the lower rail 30 is provided with an axial groove 31 along the axial direction, and a notch 311 is provided at the top of the axial groove 31. The axial groove 31 is provided with a shaft rod 32, and the shaft rod 32 is provided with a buckle groove 321 along the axial direction. The bottom end of the Roman blind body 40 is provided with a fixing plate 45 and The buckle groove 321 of the shaft 32 is embedded, and then the Roman blind body 40 is wound around the shaft 32 and axially penetrated into the shaft groove 31. A cover plate 33 is fixed to the left and right ends of the lower rail 30 respectively; in addition, the Roman blind body 40 can be wrapped around the outer periphery of the lower rail 30, as shown in Figures 7 and 8.

To further explain, the present invention is provided with two first reels 11 and two second reels 12 inside the upper rail 10, the two first reels 11 reel in and release the two first rope bodies 13, and the two first reels 11 are connected to the first pull rope 15 through a first drive shaft 111 for actuation, and the two second reels 12 reel in and release the two second rope bodies 14. The second reels 12 are connected to the second puller 16 via a second drive shaft 121. The middle rail 20 is provided with a connecting hole 21 and a through hole 22 at both ends. Each horizontal bar 41 of the Roman curtain body 40 is provided with two buckle members 44, wherein the positions of the two buckle members 44 on the horizontal bar 41 are aligned with the two buckle members 44 of the middle rail 20. The two ends of the first rope bodies 13 are fixed to the two connecting holes 21 of the middle rail 20, and the two second rope bodies 14 pass through the two holes 22 of the middle rail 20 and the buckle member 44 in sequence from top to bottom. Finally, the ends of the second rope bodies 14 are fixed to the buckle member 44 at the last position, thereby completing the embodiment of the dimming Roman blind. When the first pull rope 15 drives the second first reel 11 to reel in or release the first rope body 13, the middle rail 20 can be driven to move up and down along the second rope bodies 14. In addition, when the second pull rope 16 drives the second reel 12 to reel in or release the second rope bodies 14, the Roman blind 40 can be driven to close or unfold.

To further explain, the Roman curtain body 40 can be selected as a light-transmitting curtain or a light-blocking curtain. In this embodiment, the Roman curtain body 40 is set as a light-blocking curtain. The above is only one implementation of this creation and should not be limited to this. It can also be set as a curtain body with a different light-transmitting or light-blocking effect according to special needs.

The use state of the structural embodiment is shown in Figures 1 and 2 in conjunction with Figure 9. The middle rail 20 and the Roman curtain 40 of this embodiment are respectively wound by the first and second ropes 13 and 14 of the first and second rope reels 11 and 12 to rise and form a fully light-transmitting state. The first rope 13 pulls the middle rail 20 to move upward and is attached to the bottom of the upper rail 10, while the second rope 14 pulls the bottom horizontal bar 41 to move upward and push the horizontal bars 41 in sequence to rise and close to the middle rail 20, so that the Roman curtain 40 between the horizontal bars 41 falls and overlaps in the direction of the opening 411.

Next, as shown in Figures 10 to 13, the Roman blind 40 is unfolded in this embodiment. The second pull rope 16 drives the second reel 12 to move and release the second rope 14. At this time, the lower rail 30 moves downward due to its own vertical weight, and pulls down the horizontal bar 41 in sequence, so that the Roman blind 40 is gradually unfolded downward from the middle rail 20. Since the Roman blind 40 is a blackout curtain, it further blocks external light to form a blackout state.

As shown in Figures 14 to 17, the middle rail 20 is displaced toward the lower rail 30 in this embodiment. The first rope puller 15 drives the two first rope reels 11 to operate and relax the two first rope bodies 13. At this time, the middle rail 20 moves downward along the two second rope bodies 14 due to its own vertical weight, so that the middle rail 20 gradually moves away from the upper rail 10, so that the upper half of the Roman curtain forms a hollow and light-transmitting state. When the middle rail 20 moves downward, the middle rail 20 moves downward along the two second rope bodies 14 and pushes the horizontal bars 41 downward in sequence, thereby folding the Roman curtain body 40 downward.

In addition, since the downward displacement of the middle rail 20 will simultaneously link the Roman curtain body 40 to fold downward, the light transmission range can be adjusted by the downward displacement of the middle rail 20 to achieve a semi-light-shielding and semi-light-transmitting effect.

Continuing from FIG. 9, it is a schematic diagram of the present embodiment in which the middle rail 20 and the Roman blind 40 are both folded upward. In general, since the first and second reels 11 and 12 are not linked to form a state of separate control, if the Roman blind 40 in the state of FIGS. 14 to 17 is directly controlled by the second pull rope 16 to control the second reels 12 to reel in the second ropes 14, although the middle rail 20 will move toward the upper rail 10, the first ropes 13 will be in a loose state because they are not reeled in, so that the first ropes 13 are easily entangled and knotted; therefore, if the middle rail 20 and the Roman blind 40 are both folded upward, the first ropes 13 will be in a loose state because the first ropes 13 are not reeled in. Therefore, if the middle rail 20 and the Roman blind 40 are both folded upward, the first ropes 13 will be in a loose state because the first ropes 13 are easily entangled and knotted. When the Roman blind is folded upward to form a fully light-transmitting state, the first pull rope 15 must first control the two first reels 11 to roll up the two first rope bodies 13, thereby driving the middle rail 20 to move upward and against the bottom of the upper rail 10, and reaching the middle rail 20 to be close to the state, at which time the Roman blind 40 is in an unfolded state, and then the second pull rope 16 controls the two second reels 12 to roll up the two second rope bodies 14, thereby driving the bottom horizontal bar 41 to move upward and sequentially offset all the horizontal bars 41 to be close to the middle rail 20, thereby reaching the state of the middle rail 20 and the Roman blind 40 being fully folded.

Another embodiment of the invention is shown in FIG. 18. The upper rail 10 may be provided with a linkage device 17 and a clutch device 18. The linkage device 17 is installed and connected between the adjacent first reel 11 and the second reel 12, and is connected to the first drive shaft 111 and the second drive shaft 121, respectively. The first and second reels 11 and 12 can achieve synchronous reeling action through the linkage device 17. The clutch device 18 is installed on the first pull rope 15 to make 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 18 forms an engagement state, so that the first pull rope 15 and the first reel 11 have a clutch effect. The first pull rope device 15 can control the reeling action of the second first reel 11. On the contrary, when the second second reel 12 synchronously links the first reel 11 to reel the first rope body 13 through the linkage device 17, the clutch device 18 will be disengaged, so that the first reel 11 will not reversely drive the first pull rope device 15 to act, thereby avoiding The first pull rope device 15 is damaged to achieve a foolproof protection effect, and further allows the user to directly control the first and second reels 11 and 12 to reel in the first and second rope bodies 13 and 14 through the second pull rope device 16 when the middle rail 20 moves down to form a light-transmitting state, so as to achieve a fully retracted state of the middle rail 20 and the Roman blind body 40.

The structure of the above-mentioned specific embodiment can achieve the following benefits: the Roman curtain 40 of the invention is arranged between the middle rail 20 and the lower rail 30, and there is no curtain between the upper rail 10 and the middle rail 20 to form a hollow curtain. The middle rail 20 and the Roman curtain 40 are respectively driven by the first and second winding ropes 11 and 12 to achieve the folding and unfolding actions, so that the Roman curtain 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 curtain, 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, and should comply with the relevant provisions of the Patent Law. Therefore, a new patent application has been filed in accordance with the law, and the Jun Bureau Review Committee is requested to grant legal patent rights, and I am 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.
