[0046] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of a composite curtain 100 provided by an embodiment of the present utility model. The embodiment of the present utility model provides a composite curtain 100, which includes a first mounting member 110, a second mounting member 120, a movable assembly 130, a first curtain body 140, and a second curtain body 150. The movable assembly 130 is located between the first mounting member 110 and the second mounting member 120. The first curtain body 140 is located between the first mounting member 110 and the movable assembly 130. The second curtain body 150 is located between the second mounting member 120 and the movable assembly 130. In this embodiment, the first mounting member 110 is located above the second mounting member 120. Therefore, in the vertical direction from top to bottom are the first mounting member 110, the first curtain body 140, the movable assembly 130, the second curtain body 150, and the second mounting member 120.
[0047] The first curtain body 140 is connected to the first mounting member 110 and the movable assembly 130, and the second curtain body 150 is connected to the second mounting member 120 and the movable assembly 130. The first curtain body 140 and the second curtain body 150 can be deployed or stacked between the first mounting member 110 and the second mounting member 120. Understandably, the first mounting member 110 and the second mounting member 120 are respectively arranged on opposite sides of the window, and the first curtain body 140 and the second curtain body 150 are deployed and stacked between the first mounting member 110 and the second mounting member 120, so as to block the light passing through the window.
[0048] It should be noted that the first curtain body 140 and the second curtain body 150 are curtain bodies made of different materials, and the structural arrangement and manufacturing process of the first curtain body 140 and the second curtain body 150 are different. Therefore, the light shielding rates of the first curtain body 140 and the second curtain body 150 are not the same.
[0049] The movable assembly 130 can move between the first mounting member 110 and the second mounting member. Since both the first curtain body 140 and the second curtain body 150 are connected to the movable assembly 130, when the movable assembly 130 moves, the deployment areas of the first curtain body 140 and the second curtain body 150 will change. Specifically, when the movable assembly 130 moves upward, the deployment area of the first curtain body 140 becomes smaller, and the deployment area of the second curtain body 150 becomes larger. When the movable assembly 130 moves downward, the deployment area of the first curtain body 140 becomes larger, and the deployment area of the second curtain body 150 becomes smaller. Thus, the movable assembly 130 can select to use the first curtain body 140 or the second curtain body 150 by changing the deployment areas of the first curtain body 140 and the second curtain body 150, so as to achieve the alternative use of the two curtain bodies.
[0050] In this embodiment, when the movable assembly 130 cannot move upward, the first curtain body 140 is completely stacked, and the deployment area of the second curtain body 150 is the maximum deployment area. When the movable assembly 130 cannot move downward, the second curtain body 150 is completely stacked, and the deployment area of the first curtain body 140 is the maximum deployment area. Among them, the maximum deployment area of the first curtain body 140 is equal to the maximum deployment area of the second curtain body 150.
[0051] It should be noted that the maximum deployment lengths of the first curtain body 140 and the second curtain body 150 are the distance between the first mounting member 110 and the second mounting member.
[0052] Further, please refer to Figure 1The movable assembly 130 includes an installation box 131 and a pull rope 132. The installation box 131 is connected to the first curtain body 140 and the second curtain body 150. The pull rope 132 is passed through the installation box 131, and the two ends of the pull rope 132 are respectively connected to the first installation member 110 and the second installation member 120. The installation box 131 and the pull rope 132 are movably matched, and the installation box 131 moves along the extension direction of the pull rope 132.
[0053] Specifically, the installation box 131 and the pull rope 132 are movably matched, wherein the pull rope 132 plays a guiding role, so that the installation box 131 can move along the extension direction of the pull rope 132. In this embodiment, the extension direction of the pull rope 132 is a vertical direction, so that the installation box 131 can move in the vertical direction, thereby driving the first curtain body 140 and the second curtain body 150 to unfold or overlap.
[0054] It should be noted that, in this embodiment, the first curtain body 140 and the second curtain body 150 are honeycomb curtains, which include a plurality of blades. The plurality of blades are all inserted into the pull cord 132, so that the first curtain body 140 and the second curtain body 150 are both unfolded or attached along the numerical direction.
[0055] In other embodiments, the first curtain body 140 and the second curtain body 150 may also be other curtain structures such as blinds or Roman blinds.
[0056] According to the above content, the installation box 131 is provided with a through hole 1312, and the pull rope 132 passes through the through hole 1312, so that the installation box 131 can move along the extension direction of the pull rope 132.
[0057] Furthermore, the movable assembly 130 further includes a first locking member 133, which is located in the installation box 131 and connected to the installation box 131; the pull rope 132 is passed through the first locking member 133; the first locking member 133 is used to lock the installation box 131.
[0058] Specifically, the composite curtain 100 is provided with a first locking member 133 so that the installation box 131 can stop moving at any position during the movement along the extension direction of the pull cord 132, that is, the installation box 131 is locked.
[0059] Thus, the locking member is opened, and the installation box 131 can be moved, thereby adjusting the expansion area of the first curtain body 140 and the second curtain body 150, so as to choose to use the first curtain body 140 or the second curtain body 150. When the user is in use, the installation box 131 can be locked by the first locking member 133, so that the installation box 131 cannot be moved, thereby locking the expansion area of the first curtain body 140 and the second curtain body 150.
[0060] For other embodiments, please refer toFigure 2 , Figure 2 This is a schematic structural diagram of the composite curtain 100 provided by other embodiments of the present utility model. The composite curtain 100 further includes a drawstring 132 and a second locking member 170. One end of the drawstring 132 is connected to the first mounting member 110; the other end of the drawstring 132 passes through the movable assembly 130 and the second mounting member 120; the second locking member 170 is connected to the second mounting member 120, and the second locking member 170 is used to lock the second mounting member 120.
[0061] Specifically, the drawstring 132 passes through the second mounting member 120 and extends downward. The second locking member 170 is arranged below the second mounting member 120. It should be noted that the second mounting member 120 is a movable member, and the second mounting member 120 moves along the extension direction of the drawstring 132. When the second locking member 170 is opened, by moving the second locking member 170, the second mounting member 120 is driven to move, so as to unfold or overlap the second curtain body 150.
[0062] When the user needs to close the curtain, the first locking member 133 and the second locking member 170 are opened, and the movable assembly 130 and the second mounting member 120 are moved upward. When the movable assembly 130 and the second mounting member 120 cannot move upward anymore, the first curtain body 140 and the second curtain body 150 are completely overlapped. Subsequently, the first locking member 133 and the second locking member 170 are locked to prevent the movable assembly 130 and the second mounting member 120 from moving downward.
[0063] Furthermore, please refer to Figures 3 - 12 , Figure 3 This is a schematic structural diagram of the locking pin 1331 in the locking position from the first perspective provided by the embodiment of the present utility model; Figure 4 is Figure 3 the cross-sectional view at A-A in Figure 5 This is a schematic structural diagram of the locking pin 1331 in the locking position from the second perspective provided by the embodiment of the present utility model; Figure 6 is Figure 5 the cross-sectional view at B-B in Figure 7 This is a schematic structural diagram of the locking pin 1331 in the unlocking position from the first perspective provided by the embodiment of the present utility model; Figure 8 is Figure 7 the structural diagram at C-C in ; This is a schematic structural diagram of the locking pin 1331 in the unlocking position from the second perspective provided by the embodiment of the present utility model; Figure 10 is Figure 9 the structural diagram at D-D in ; Figure 11 This is a schematic structural diagram of the movable member provided by the embodiment of the present utility model; Figure 12 This is a schematic structural diagram of the fixed member provided by the embodiment of the present utility model.
[0064] In this embodiment, the first locking member 133 includes a locking pin 1331 and a sleeve 1332. The sleeve 1332 is sleeved on the locking pin 1331; the sleeve 1332 is connected to the mounting box 131. The locking pin 1331 is movably engaged with the sleeve 1332, and the locking pin 1331 has at least an unlocking position and a locking position. The locking pin 1331 is provided with a first through hole 1334, and the sleeve 1332 is provided with a second through hole 1335; the pull rope 132 is passed through the first through hole 1334 and the second through hole 1335; when the first through hole 1334 is in the locking position, the pull rope 132 abuts against the outer wall of the locking pin 1331. When the locking pin 1331 is in the locking position, the locking pin 1331 and the pull rope 132 are jointly used to clamp the pull rope 132. Specifically, when the first through hole 1334 of the locking pin 1331 is in the locking position, the first through hole 1334 and the second through hole 1335 are misaligned. At this time, the pull rope 132 abuts against the outer wall of the locking pin 1331, and the pull rope 132 is clamped by the locking pin 1331 and the sleeve 1332, resulting in the first locking member 133 being unable to move, so that the first locking member 133 is locked. Thus, the first locking member 133 locks the mounting box 131, making the mounting box 131 unable to move.
[0065] When the first through hole 1334 of the locking pin 1331 is in the unlocking position, the first through hole 1334 is aligned with the second through hole 1335. At this time, the first locking member 133 is unlocked, so that the sleeve 1332 can drive the mounting box 131 to move along the extending direction of the pull rope 132, thereby changing the unfolding area of the first curtain body 140 and the second curtain body 150, so as to selectively use the first curtain body 140 and the second curtain body 150. Thus, by selectively using curtains with different light-shielding rates, the living comfort of people is improved.
[0066] According to the above structural settings, please refer to Figures 1 - 10 , the first locking member 133 further includes a spring 1333. The two ends of the spring 1333 are connected to the locking pin 1331 and the sleeve 1332; the spring 1333 elastically acts on the locking pin 1331, so that the locking pin 1331 has a tendency to move from the unlocking position to the locking position.
[0067] Specifically, under the action of an external force, the locking pin 1331 is moved from the locking position to the unlocking position; at this time, the spring 1333 is compressed. After the external force disappears, the locking pin 1331 moves from the unlocking position to the locking position under the action of the restoring force of the spring 1333.
[0068] According to the above content, please refer to Figures 1 - 12 , the locking pin 1331 is provided with a guiding groove 1336, and the inner wall of the sleeve 1332 is provided with a sliding portion 1337; the sliding portion 1337 is slidably engaged with the guiding groove 1336.
[0069] Specifically, when the first through hole 1334 is in the locked position, the sliding portion 1337 abuts against the front end of the guiding groove 1336, thereby preventing the locking pin 1331 from disengaging. Moreover, by providing the sliding portion 1337 and the guiding groove 1336, the locking pin 1331 is prevented from deflecting, and the rotation of the locking pin 1331 is avoided, which may cause the first through hole 1334 not to be aligned with the second through hole 1335, resulting in the inability to unlock the first locking member 133.
[0070] Further, please refer to Figures 1 - 14 , Figure 13 which is a schematic structural view of the transmission member 160 and the first locking member 133 provided by an embodiment of the present invention; Figure 14 which is a schematic structural view of the mounting box 131 provided by an embodiment of the present invention.
[0071] When the areas of the first curtain body 140 and the second curtain body 150 are too large, the volume of the mounting box 131 increases accordingly, and its weight also increases. Therefore, a plurality of draw ropes 132 and a plurality of first locking members 133 are provided to enable the mounting box 131 to be locked.
[0072] Each draw rope 132 passes through a first locking member 133; the composite curtain 100 further includes a transmission member 160; the mounting box 131 is provided with a third through hole 1311; the transmission member 160 is connected to a plurality of locking pins 1331 through the third through hole 1311, and the transmission member 160 is used to drive the plurality of locking pins 1331 to move synchronously. A plurality of through holes 1312 are provided, and each draw rope 132 passes through a through hole 1312; the axial direction of the through hole 1312 is perpendicular to the axial direction of the third through hole 1311.
[0073] It should be noted that the plurality of first locking members 133 are arranged in parallel and at intervals, and among them, the locking pins 1331 are located on the same side. Among them, the axial direction of the third through hole 1311 is parallel to the axial direction of the sleeve 1332, so that when the transmission member 160 is driven to move, the transmission member 160 can drive the plurality of locking pins 1331 to move along the axial direction of the sleeve 1332.
[0074] According to the above arrangement, the transmission member 160 includes a connecting portion 161 and a transmission portion 162; the connecting portion 161 is located inside the mounting box 131, and the connecting portion 161 is connected to a plurality of locking pins 1331; one end of the transmission portion 162 is connected to the connecting portion 161 through the third through hole 1311, and the transmission portion 162 is movably engaged with the third through hole 1311. Specifically, by pressing the transmission portion 162, the transmission portion 162 and the connecting portion 161 move along the axial direction of the third through hole 1311. Thereby driving the plurality of locking pins 1331 to move synchronously, and further causing the first through holes 1334 of the plurality of locking pins 1331 to move from the locked position to the unlocked position, so as to adjust the unfolded areas of the first curtain body 140 and the second curtain body 150.
[0075] Understandably, in this embodiment, the connecting portion 161 is a rod structure, and the extending direction of the connecting portion 161 is perpendicular to the axial direction of the third through hole 1311. The transmission portion 162 is located at the middle position of the connecting portion 161.
[0076] In summary, the composite curtain 100 includes a first curtain body 140 and a second curtain body 150. The materials and structures of the first curtain body 140 and the second curtain body 150 are different, so that the light shielding rates of the first curtain body 140 and the second curtain body 150 are different. Both the first curtain body 140 and the second curtain body 150 can be unfolded or stacked between the first mounting member 110 and the second mounting member 120.
