[0032] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] The terms "first," "second," "third," "fourth," etc. (if any) in the description and claims of this application are used to distinguish similar objects and not necessarily to describe a particular sequence or order.

[0034] The terms "up," "down," "left," "right," "front," "back," "top," and "bottom" (if any) used in the specification and claims of this application are defined by the positions of structures in the accompanying drawings and the positions of structures relative to each other. These terms are intended solely for clarity and convenience in presenting the technical solution. It should be understood that the use of these terms does not limit the scope of protection claimed in this application.

[0035] As shown in Figures 1 and 2, the curtain provided in an embodiment of the present application includes an upper curtain rod 1, a lower curtain rod 2, a first curtain body 3, a second curtain body 4, a pull cord 5, and a cord winder 6. The upper curtain rod 1 is positioned above the lower curtain rod 2 (as shown in Figures 1 and 2, arrow X indicates the left-right direction, arrow Y indicates the up-down direction, and arrow Z indicates the forward-backward direction). The upper curtain rod 1 is spaced vertically from the lower curtain rod 2. The upper curtain rod 1 can be secured to a desired location (e.g., on a wall) using bolts, screws, or other components, thereby securing the curtain in the desired position.

[0036] The first curtain body 3 and the second curtain body 4 are arranged in a front-to-back relationship, each positioned between the upper curtain rod 1 and the lower curtain rod 2. The top ends of the first curtain body 3 and the second curtain body 4 are both fixedly connected to the upper curtain rod 1, while the bottom ends of the first curtain body 3 and the second curtain body 4 are both fixedly connected to the lower curtain rod 2. The first curtain body 3 is a Roman shade, and the second curtain body 4 is a pleated shade or a cellular shade (both pleated shades and cellular shades share a folding structure, comprising multiple folding units 41). The second curtain body 4 comprises multiple folding units 41 connected in sequence from top to bottom; at least some of the folding units 41 in the second curtain body 4 are connected to the first curtain body 3. As a result, when the second curtain body 4 is folded upward or extended downward, the first curtain body 3 can fold or unfold along with the second curtain body 4.

[0037] A cord winder 6 is fixedly mounted within the upper curtain rod 1. One end of the draw cord 5 is connected to the cord winder 6, while the other end of the draw cord 5 is connected to the lower curtain rod 2. The draw cord 5 is also connected to the multiple folding units 41 in the second curtain body 4. The cord winder 6 is used to position the curtain when it is folded upward (i.e., the cord winder 6 can fix the draw cord 5 at any extended length), thereby positioning the curtain in any folded position.

[0038] The curtain provided in this embodiment is provided with a first curtain body 3 and a second curtain body 4. The first curtain body 3 is a Roman shade, and the second curtain body 4 is a pleated shade or a honeycomb shade. The first curtain body 3 and the second curtain body 4 are arranged in a front-to-back relationship. During use, the user can select one of the first curtain body 3 and the second curtain body 4 to face the user (for example, toward the room) and the other to face away from the user (for example, toward the outside). After using the curtain for a period of time, the user can turn the curtain over so that the back of the curtain faces the user. Because the first curtain body 3 and the second curtain body 4 are two different curtain bodies, the user can observe different types of curtain bodies, thereby improving the aesthetics and freshness, meeting the different needs of users, and eliminating the need to replace the curtain, thus saving costs.

[0039] At the same time, at least some of the folding units 41 in the second curtain body 4 are connected to the first curtain body 3. When the second curtain body 4 is folded, the first curtain body 3 can fold along with it, achieving a simultaneous folding effect. This eliminates the need for a pull cord or other components on the first curtain body 3 for folding the first curtain body 3, thus saving costs. Furthermore, this double-layer curtain structure can improve the light-blocking and privacy-blocking effects of the curtain compared to a single-layer curtain.

[0040] As an embodiment, the first curtain body 3 and the second curtain body 4 are different colors, so that when the user turns the curtain over, they can see the curtain bodies of different colors, further improving the aesthetics and freshness. Of course, in other embodiments, the first curtain body 3 and the second curtain body 4 can also be the same color.

[0041] As an embodiment, the materials of the first curtain body 3 and the second curtain body 4 can be the same or different. The patterns and colors of the first curtain body 3 and the second curtain body 4 can be the same or different.

[0042] As shown in Figures 1 and 2 , in one embodiment, the second curtain body 4 is a pleated curtain, and the folding units 41 therein are V-shaped. As shown in Figure 6 , in another embodiment, the second curtain body 4 is a honeycomb curtain, and the folding units 41 therein are tubular (specifically, the cross-section of the folding units 41 may be hexagonal). The specific structures of pleated curtains and honeycomb curtains can be found in the prior art and will not be elaborated upon here.

[0043] As shown in Figures 1 and 2 , as one embodiment, the first curtain body 3 includes a plurality of vertically arranged folding segments 31 and a connecting portion 32 connecting each pair of vertically adjacent folding segments 31. The connecting portion 32 is integral with the folding segments 31 and is connected to the folding units 41 in the second curtain body 4. Each folding segment 31 corresponds to a plurality of folding units 41 in the second curtain body 4, meaning that the height of a folding segment 31 is equal to the height of the plurality of folding units 41 (i.e., the height of a folding segment 31 is greater than the height of a single folding unit 41). When the curtain is draped downward, the folding segments 31 are planar (as shown in Figures 1 and 2 ). When the curtain is folded upward, the folding segments 31 bend, and the plurality of folding segments 31 overlap.

[0044] As shown in Figures 1 and 2 , as one embodiment, a folded edge 411 of the folding unit 41 (the folded edge 411 is located at the bend of the folding unit 41) is connected to the first curtain body 3. Specifically, along the front-to-back direction Z, the folding unit 41 is provided with folded edges 411 on opposite sides. The folded edge 411 on the side of the folding unit 41 closest to the first curtain body 3 is connected to the first curtain body 3.

[0045] As shown in Figures 1 to 3 , in one embodiment, the folding unit 41 is connected to the first curtain body 3 via a connector 7 (specifically, the folded edge 411 of the folding unit 41 is connected to the connecting portion 32 of the first curtain body 3 via the connector 7). Multiple connectors 7 are provided, spaced vertically apart, and are respectively connected between different folding units 41 in the second curtain body 4 and different locations on the first curtain body 3. The connectors 7 can be made of metal, plastic, or other materials. Of course, in other embodiments, the folding unit 41 and the first curtain body 3 can also be connected by sewing, gluing, or other methods.

[0046] As shown in FIG. 1 and FIG. 2 , as an embodiment, a plurality of connecting members 7 are arranged at equal intervals in the upper and lower parts, so that the plurality of folding sections 31 can be evenly stacked together after being folded, thereby improving the aesthetics.

[0047] As shown in Figures 1 to 3, as one embodiment, the connecting member 7 is located between the folding unit 41 and the first curtain body 3. The connecting member 7 includes a connecting rod 71, a first blocking bar 72, and a second blocking bar 73. Each of the connecting rod 71, the first blocking bar 72, and the second blocking bar 73 is an elongated structure. A first engaging slot 713 is provided on the side of the connecting rod 71 facing the first curtain body 3, with a notch 713a of the first engaging slot 713 located on the side of the connecting rod 71 facing the first curtain body 3. A second engaging slot 714 is provided on the side of the connecting rod 71 facing the second curtain body 4, with a notch 714a of the second engaging slot 714 located on the side of the connecting rod 71 facing the second curtain body 4. The first blocking bar 72 is located within the first engaging slot 713, and the second blocking bar 73 is located within the second engaging slot 714. A portion of the first curtain body 3 is retained within the first engaging slot 713 by the first blocking bar 72, while the folded edge 411 of the folding unit 41 is retained within the second engaging slot 714 by the second blocking bar 73.

[0048] Specifically, in this embodiment, the first blocking bar 72 and the second blocking bar 73 are both cylindrical structures, and the first engaging groove 713 and the second engaging groove 714 are both circular grooves, resulting in a cross-section of the connecting rod 71 having an "8" shape with both ends open. Furthermore, the diameter of the first blocking bar 72 is smaller than the inner diameter of the first engaging groove 713 and larger than the size of the notch 713a of the first engaging groove 713, allowing the first blocking bar 72 to be retained within the first engaging groove 713 and prevent it from falling out. The diameter of the second blocking bar 73 is smaller than the inner diameter of the second engaging groove 714 and larger than the size of the notch 714a of the second engaging groove 714, allowing the second blocking bar 73 to be retained within the second engaging groove 714 and prevent it from falling out. Part of the first curtain body 3 wraps around the first blocking bar 72 (i.e., is wrapped around the first blocking bar 72), so that the first blocking bar 72 can clamp the first curtain body 3 into the first clamping groove 713; the folded edge 411 of the folding unit 41 wraps around the second blocking bar 73 (it is easy to understand that because the folded edge 411 of the folding unit 41 wraps around the second blocking bar 73, the shape of the folded edge 411 of the folding unit 41 changes with the shape of the second blocking bar 73: i.e., from the original sharp angle to the arc shape), so that the second blocking bar 73 can clamp the folding unit 41 into the second clamping groove 714, thereby achieving the connection between the first curtain body 3 and the second curtain body 4.

[0049] As shown in Figures 2 and 3 , as one embodiment, the connecting portion 32 protrudes from the surface of the first curtain body 3. The connecting portion 32 is formed by bending a portion of the first curtain body 3 so that it protrudes from the surface of the first curtain body 3. The connecting portion 32 wraps around the first blocking bar 72 (as will be readily understood, since the connecting portion 32 wraps around the first blocking bar 72, the shape of the connecting portion 32 changes with the shape of the first blocking bar 72, i.e., the connecting portion 32 is arc-shaped). The connecting portion 32 is retained in the first retaining groove 713 by the first blocking bar 72.

[0050] As shown in Figures 2 and 3 , as one embodiment, the connecting rod 71 includes a first long tube 711 and a second long tube 712 that are interconnected and form an integral structure. A first engaging slot 713 is provided on the first long tube 711, with the opening of the first engaging slot 713 located on the side of the first long tube 711 near the first curtain body 3 ; a second engaging slot 714 is provided on the second long tube 712, with the opening of the second engaging slot 714 located on the side of the second long tube 712 near the second curtain body 4 .

[0051] As shown in FIG3 , as one embodiment, an opening 710 is provided at the end of the connecting rod 71 along its length. The opening 710 communicates with both the first and second slots 713, 714. The first and second blocking bars 72, 73 can be installed into the first and second slots 713, 714 through the opening 710. The connector 7 further includes a blocking member 74, which is disposed at the end of the connecting rod 71 and blocks the opening 710, thereby preventing the first and second blocking bars 72, 73 from escaping from the slots through the opening 710. The blocking member 74 is fixed to the end of the connecting rod 71.

[0052] As shown in FIG. 3 , as an embodiment, openings 710 are provided at opposite ends of the connecting rod 71 along its length, and blocking members 74 are provided at opposite ends of the connecting rod 71 .

[0053] As shown in FIG. 3 , as an embodiment, the blocking member 74 includes an inserting portion 741 and a stopping portion 742 connected to each other. The inserting portion 741 is inserted into the first slot 713 and / or the second slot 714 , and the stopping portion 742 covers the opening 710 .

[0054] As shown in FIG1 , FIG4 and FIG5 , as an embodiment, a mounting groove 11 is provided on the upper curtain rod 1 , and the rope winder 6 is arranged in the mounting groove 11 . The rope winder 6 and the upper curtain rod 1 can be fixed by screws or the like.

[0055] As shown in Figures 1, 4, and 5, as one embodiment, there are two draw cords 5, one on each side of the curtain. The cord reel 6 has a dual-cord structure (i.e., one reel 6 is connected to two draw cords 5). The cord reel 6 comprises a base 61, a winding drum 62 disposed within the base 61, a rotating drum 63, and a coil spring 64. Two winding drums 62 are located on opposite sides of the rotating drum 63. A first fixing post 65 and a second fixing post 66 are spaced apart within the base 61 and fixed to the inner wall of the base 61. The winding drum 62 is mounted on and rotatable around the first fixing post 65, while the rotating drum 63 is mounted on and rotatable around the second fixing post 66. The winding drum 62 is equipped with a first gear 621, and the rotating drum 63 is equipped with a second gear 631. The first gear 621 and the second gear 631 mesh; that is, the first gear 621 on both winding drums 62 meshes with the second gear 631 on the rotating drum 63. A coil spring 64 is disposed between the rotating drum 63 and the second fixing post 66. The inner end of the coil spring 64 is connected to the second fixing post 66, and the outer end of the coil spring 64 is connected to the rotating drum 63. The draw cord 5 is wound around the winding drum 62, with one end of the draw cord 5 extending outside the base 61. The two draw cords 5 are connected to the two winding drums 62. When the curtain is draped downward and the draw cord 5 is pulled outward from the base 61, the winding drum 62 rotates, driving the rotating drum 63 to rotate, thereby accumulating force in the winding spring 64. When the curtain is folded upward, the rotating drum 63 rotates under the elastic force of the winding spring 64, driving the winding drum 62 to rotate, thereby reeling the draw cord 5 and winding it around the winding drum 62, thereby reducing the extended length of the draw cord 5. Simultaneously, the two winding drums 62 and the rotating drum 63 rotate synchronously, allowing a single cord reel 6 to reel in and unreel two draw cords 5.

[0056] Specifically, during use, when the curtain is hanging down, the user can pull the lower curtain rod 2 downward with his hand. At this time, the extended length of the draw cord 5 increases, and the draw cord 5 drives the winding drum 62 to rotate to pay out the line. The rotation of the winding drum 62 drives the rotating drum 63 to rotate, and the rotation of the rotating drum 63 drives the winding spring 64 to rotate, so that the winding spring 64 accumulates force; when the curtain is folded and retracted upward, the user can lift the lower curtain rod 2 upward with his hand. At this time, the extended length of the draw cord 5 decreases, and the rotating drum 63 rotates under the elastic force of the winding spring 64 and drives the winding drum 62 to rotate. The winding drum 62 takes up the line to wind the draw cord 5 around the winding drum 62 (for the specific structure and working principle of the rope reel 6, please refer to patents such as CN215859915U and CN206571402U).

[0057] As shown in Figure 8 , in another embodiment, the rope reel 6 is a single-rope structure, with each rope reel 6 connected to a single pull rope 5. Each rope reel 6 includes a winding drum 62 located on one side of a rotating drum 63. This winding drum 62 is connected to a single pull rope 5 to reel in and release the single pull rope 5. In this case, two rope reels 6 are required, each connected to two pull ropes 5 to reel in and release the two pull ropes 5.

[0058] As shown in Figures 1 and 2 , as one embodiment, each folding unit 41 is provided with a cord insertion hole 410, through which a draw cord 5 passes, thereby enabling the folding and unfolding of each folding unit 41. As one embodiment, the cord insertion hole 410 is located in the middle of the folding unit 41 along the front-to-back direction Z. As shown in Figures 2 and 6 , this cord insertion structure can be used regardless of whether the second curtain body 4 is a pleated curtain or a honeycomb curtain.

[0059] As shown in Figure 7 , in another embodiment, each folding unit 41 is provided with a raised ring portion 42. This ring portion 42 is an annular structure that protrudes from the surface of the second curtain body 4. The ring portion 42 and the folding unit 41 can be integral (for example, if the second curtain body 4 is woven from silk thread, the ring portion 42 is part of the silk thread in the second curtain body 4) or separate (for example, the ring portion 42 can be bonded to the folding unit 41). A drawstring 5 passes through the ring portion 42 on each folding unit 41, allowing the folding and unfolding of each folding unit 41 to be achieved using the drawstring 5. This approach eliminates the need for drilling holes in the second curtain body 4, thereby improving aesthetics. Preferably, the ring portion 42 is located at the folded edge 411 of the folding unit 41, on the side of the folding unit 41 away from the first curtain body 3. This cord-threading arrangement can be used regardless of whether the second curtain body 4 is a pleated curtain or a honeycomb curtain (Figure 7 illustrates a pleated curtain as the second curtain body 4).

[0060] As shown in Figure 9 , as another embodiment, each folding unit 41 has a flange 43 on its folded edge 411 facing away from the first curtain body 3 (of course, the flange 43 can also be provided on the folded edge 411 facing the first curtain body 3). The flange 43 is integral with the folding unit 41 and is a long, strip-shaped structure extending in the left-right direction X (the flange 43 and the folding unit 41 have the same dimensions in the left-right direction X). A through-hole 430 is provided in the flange 43. A pull cord 5 passes through the through-hole 430 in the flange 43 of each folding unit 41, thereby enabling the folding and unfolding of each folding unit 41. This method eliminates the need for drilling holes in the second curtain body 4, thereby improving the aesthetics. As shown in Figures 9 and 10 , this cord-threading structure can be used regardless of whether the second curtain body 4 is a pleated curtain or a honeycomb curtain (Figure 9 illustrates a pleated curtain, while Figure 10 illustrates a honeycomb curtain).

[0061] Of course, in other embodiments, when the folding edge 411 of the folding unit 41 is provided with a flange portion 43, a rope threading structure as shown in FIG. 2 or FIG. 6 may also be adopted, that is, the folding unit 41 is provided with a rope threading hole 410, and the pull rope 5 is passed through the rope threading hole 410 on each folding unit 41, thereby utilizing the pull rope 5 to realize the folding and hanging of each folding unit 41. In this case, the pull rope 5 does not pass through the flange portion 43, and the flange portion 43 serves an aesthetic purpose.

[0062] The curtain provided in the embodiment of the present application is provided with a first curtain body 3 and a second curtain body 4. The first curtain body 3 is a Roman shade, and the second curtain body 4 is a pleated shade or a honeycomb shade. The first curtain body 3 and the second curtain body 4 are arranged in a front-to-back relationship. During use, the user can select one of the first curtain body 3 and the second curtain body 4 to face the user (for example, toward the room) and the other to face away from the user (for example, toward the outside). After using the curtain for a period of time, the user can turn the curtain over so that the back of the curtain faces the user. Since the first curtain body 3 and the second curtain body 4 are two different curtain bodies, the user can observe different types of curtain bodies, thereby improving the aesthetics and freshness, meeting the different needs of users, and eliminating the need to replace the curtain, thus saving costs.

[0063] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
