Technical Field

[0001] This application relates to the field of projection technology, and in particular to an inflatable screen. Background Technology

[0002] In related technologies, there is an inflatable screen that is not inflated when not in use for easy storage; when in use, the inflatable screen is inflated to unfold it, making it relatively flat so that the projection device can project images onto the screen.

[0003] However, inflatable screens are usually used outdoors. Since they are inflated before use, they are lightweight and may be blown over or shaken by the wind, affecting the viewing experience. Utility Model Content

[0004] This application provides an inflatable screen that can improve the installation stability of the inflatable screen when used outdoors and enhance the viewing experience.

[0005] The first aspect of this application provides an inflatable screen, comprising: The curtain itself; An inflatable frame is connected to the curtain body. When the inflatable frame is in use, it is inflated to support the curtain body when it is unfolded. Windproof ropes, connected to the inflatable frame, are used to secure the inflatable frame to the ground; and A storage component, connected to the inflatable frame, is used to store the windproof rope when not in use.

[0006] Furthermore, when the inflatable frame is in use, the storage component is located in the upper half of the inflatable frame.

[0007] Furthermore, when the inflatable frame is in use, the height of the storage component is not less than 150 cm and not more than 180 cm.

[0008] Furthermore, the storage component includes: A storage bag is attached to the inflatable frame. The storage bag has a storage cavity and a storage opening communicating with the storage cavity. A portion of the windproof rope can be stored in the storage cavity through the opening.

[0009] Furthermore, the storage bag is glued, hung, or snapped onto the inflatable frame.

[0010] Furthermore, the inflatable frame includes: The frame includes two vertical air columns and two horizontal air columns. The two vertical air columns are respectively connected to the left and right edges of the curtain body, and the two horizontal air columns are respectively connected to the top and bottom edges of the curtain body. Two support frames are disposed on the left and right sides of the whole formed by the two vertical air columns and are respectively connected to the two vertical air columns to support the two vertical air columns respectively. At least two of the windproof ropes are respectively connected to the two vertical air columns, and at least two of the storage bags are respectively connected to the two support frames or at least two of the storage bags are respectively connected to the two vertical air columns, and the connection position of the windproof ropes to the vertical air columns is higher than that of the storage bags.

[0011] Furthermore, each of the aforementioned support frames includes: The front support air column is connected at its top to the vertical air column and is located on the front side of the curtain body; The rear support air column, with its top end connected to the vertical air column and located on the rear side of the curtain body, and its top end connected to the top end of the front support air column at an acute angle; and The bottom support air column is connected at both ends to the bottom ends of the front support air column and the bottom ends of the rear support air column, respectively. The storage bag is attached to the acute angle connection between the front support air column and the rear support air column, and the horizontal cross-section of the storage cavity gradually increases from top to bottom.

[0012] Furthermore, the bottom support air column includes: The front support section is connected at its front end to the bottom end of the front support air column; and The rear support section is connected at its rear end to the bottom end of the rear support air column, and at its front end to the rear end of the front support section at an obtuse angle.

[0013] Furthermore, it also includes: At least two pull rings, each of the two pull rings being connected to one of the two vertical air columns; At least two of the windproof ropes are respectively threaded through at least two of the pull rings, and the two free ends of each windproof rope can be stored in the adjacent storage bag.

[0014] A second aspect of this application provides an inflatable screen, comprising: The curtain itself; An inflatable frame includes a perimeter frame connected to the peripheral edge of the curtain body and two support frames respectively disposed on the left and right sides of the perimeter frame, each support frame comprising: A front support air column, the top of which is connected to the frame and located on the front side of the curtain body; The rear support air column is connected at its top to the frame and located behind the curtain body, with its top end forming an acute angle with the top end of the front support air column; and The bottom support air column is connected at both ends to the bottom ends of the front support air column and the rear support air column, respectively.

[0015] Based on the inflatable screen provided in this application, by setting windproof ropes, the number of fixed points between the inflatable frame and the ground can be increased, reducing the probability that the inflatable screen will be blown by the wind or shake when used outdoors, so that the inflatable screen can be fixed to the ground more stably and improve the viewing effect.

[0016] The storage unit serves at least two purposes: First, it stores the windproof ropes, preventing them from swinging randomly to any position and making them easy to retrieve next time. Second, after the windproof ropes are fixed to the inflatable frame, they have a first fixed point on the frame. Furthermore, after being stored in the storage unit, they have a second fixed point on the unit. Therefore, once stored, the windproof ropes are relatively fixed in position and will not swing randomly. For the next use, simply remove the windproof ropes from the storage unit and fix them to the ground to install the inflatable screen. This eliminates the need to fix the windproof ropes to the inflatable frame, making the inflatable screen more convenient to use. Attached Figure Description

[0024] In related technologies, there is an inflatable screen that is not inflated when not in use for easy storage; when in use, the inflatable screen is inflated to unfold it, making it relatively flat so that the projection device can project images onto the screen.

[0025] However, inflatable screens are usually used outdoors. Since inflatable screens are used after being inflated, they are relatively lightweight and may be blown over or shaken by the wind, affecting the viewing experience.

[0026] To resolve the above issues, please refer to Figure 1-2 This application provides an inflatable screen 1, which includes a screen body 10 and an inflatable frame 20.

[0027] The screen body 10 is the main part of the inflatable screen 1, used by the projection device to project images onto it, so that the screen body 10 displays the image to be output by the projection device. Specifically, the screen body 10 is generally rectangular, with a regular shape, so that the aspect ratio of the image projected onto the screen body 10 is more suitable and will not be excessively distorted. The screen body 10 is made of flexible material to facilitate folding and storage.

[0028] The inflatable frame 20 is connected to the screen body 10. As the name suggests, the inflatable frame 20 is a frame that can be inflated and deflated. When using the inflatable frame 20, air can be injected into the inflatable frame 20 through the air nozzle 60, so that the inflatable frame 20 is in an inflated state to have a certain strength. When the inflatable frame 20 is in use, it has two functions: First, it unfolds the screen body 10, which was originally in a folded or wrinkled state, so that the screen body 10 is in a flat unfolded state; Second, when the inflatable frame 20 is placed in an appropriate posture, such as vertically, it can support the screen body 10 in the unfolded state, so that the projection device can project the image onto the screen body 10, reducing the probability of image distortion and unnecessary diffuse reflection on the screen body 10.

[0029] When the inflatable screen 1 is not in use, the gas inside the inflatable frame 20 can be released through the air nozzle 60, so that the inflatable frame 20 and the screen body 10 can be folded or crumpled into a ball, making it easy to store the inflatable screen 1, for example, by storing the folded inflatable screen 1 in the storage bag 41.

[0030] In some embodiments, the inflatable screen 1 further includes a windproof rope 30, which is used to connect to the inflatable frame 20 and to secure the inflatable frame 20 to the ground. For example, the windproof rope 30 can be fixed to the ground by ground stakes or directly tied to a fixed object on the ground (such as a tree, stone, etc.).

[0031] By setting up windproof ropes 30, the number of fixed points between the inflatable frame 20 and the ground can be increased, reducing the probability that the inflatable screen 1 will be blown by the wind or shake when used outdoors, so that the inflatable screen 1 can be fixed to the ground more stably and improve the viewing experience.

[0032] Please see Figure 1-3 In some embodiments, the inflatable screen 1 further includes a storage component 40, which is connected to the inflatable frame 20 and is used to store the windproof ropes 30 when not in use. Exemplarily, the storage component 40 can be a frame structure or a bag-like structure, as long as it can store the windproof ropes 30. This embodiment does not limit the specific form of the storage component 40. Furthermore, the storage component 40 can be made of a flexible material, making it easy to fold or crumple, thus avoiding interference or obstruction to the storage of the inflatable screen 1.

[0033] The storage component 40 serves at least two purposes: First, it stores the windproof rope 30, preventing it from swinging randomly to any position and making it easier to retrieve next time. Second, after the windproof rope 30 is fixed to the inflatable frame 20, it has a first fixed point on the frame. Furthermore, after being stored in the storage component 40, it has a second fixed point. Therefore, once stored in the storage component 40, the windproof rope 30 is relatively fixed and will not swing randomly. For the next use, the windproof rope 30 can be directly removed from the storage component 40 and fixed to the ground to install the inflatable screen 1. This eliminates the need to fix the windproof rope 30 to the inflatable frame 20, making the use of the inflatable screen 1 more convenient.

[0034] Please continue reading. Figure 1 In some embodiments, when the inflatable frame 20 is in use, that is, when the inflatable frame 20 is in an inflated state and is placed vertically, the storage component 40 is located in the middle or upper part of the inflatable frame 20. In this way, when storing the windproof rope 30 in the storage component 40, the user does not need to bend over or stand on tiptoe to conveniently store the windproof rope 30 in the storage component 40.

[0035] Understandably, users can also deflate the inflatable frame 20 first, and then store the windproof rope 30 in the storage unit 40. In this way, the windproof rope 30 can also be conveniently stored in the storage unit 40.

[0036] In some embodiments, when the inflatable frame 20 is in use, the height of the storage component 40 is no less than 150 cm and no more than 180 cm. Since most users are no less than 150 cm and no more than 180 cm tall, and users can raise or lower their hands, the reachable range of the hands used to grasp or hold the windproof rope 30 is between 140 cm and 200 cm without bending over or standing on tiptoe. Therefore, by setting the height of the storage component 40 to no less than 150 cm and no more than 180 cm, users can simply place their hands naturally in front of their chest, without bending over or standing on tiptoe, and without raising or lowering their hands, to store the windproof rope 30 in the storage component 40. For example, when the inflatable frame 20 is in use, the height of the storage component 40 is 150CM, 157CM, 160CM, 175CM, and 180CM, etc.

[0037] Please see Figure 3 In some embodiments, the storage component 40 includes a storage bag 41 connected to the inflatable frame 20. By setting the storage component 40 as a storage bag 41 and connecting the storage bag 41 to the inflatable frame 20, when storing the inflatable screen 1, since the storage bag 41 is deformable, it can be folded and stored together with the inflatable frame 20 and the screen body 10. The storage bag 41 does not obstruct the folding and storage process of the inflatable frame 20 and the screen body 10.

[0038] Furthermore, the storage bag 41 has a storage cavity (not shown in the figure) and a storage opening 41a communicating with the storage cavity. A portion of the windproof rope 30 can be stored in the storage cavity through the storage opening 41a. The storage cavity is relatively large and can accommodate a longer windproof rope 30. The storage opening 41a is relatively small compared to the storage cavity. After the windproof rope 30 is stored in the storage bag 41, the storage opening 41a can prevent the windproof rope 30 from coming out of the storage cavity when not operated by the user. That is, the windproof rope 30 is stably stored in the storage cavity.

[0039] In some embodiments, the storage bag 41 is attached to the inflatable frame 20. For example, the storage bag 41 can be attached to the inflatable frame 20 via Velcro, allowing the storage bag 41 to be attached and detached from the inflatable frame 20 multiple times. Furthermore, by providing multiple Velcro straps on the inflatable frame 20, the storage bag 41 can also be attached to different Velcro straps to more flexibly adjust its position on the inflatable frame 20.

[0040] In some embodiments, the storage bag 41 is hung on the inflatable frame 20. Thus, when the inflatable frame 20 is in use, simply hanging the storage bag 41 on it is sufficient, making the process simple and convenient. For example, a hook can be provided on the inflatable frame 20, and a hanging hole can be provided on the storage bag 41. The storage bag 41 can be hung on the inflatable frame 20 by inserting the hanging hole into the hook.

[0041] In some embodiments, the storage bag 41 is snapped onto the inflatable frame 20. Thus, when the inflatable frame 20 is in use, simply snapping the storage bag 41 onto it is sufficient. The process of installing the storage bag 41 onto the inflatable frame 20 is simple and convenient, and the snapping point between the storage bag 41 and the inflatable frame 20 is more stable, preventing the storage bag 41 from being easily blown around by the wind. For example, a hook can be provided on the inflatable frame 20, and a slot can be provided on the storage bag 41. The storage bag 41 can be snapped onto the inflatable frame 20 by inserting the hook into the slot.

[0042] Please see Figure 1-2 In some embodiments, the inflatable frame 20 includes a surrounding frame 21. The surrounding frame 21 is connected to the peripheral edge of the screen body 10. When inflated, the surrounding frame 21 unfolds to form a rectangular frame, thereby expanding the screen body 10 and placing it in an unfolded state. This prevents the image on the screen body 10 from being distorted.

[0043] In some embodiments, the frame 21 includes two vertical air columns 211 and two horizontal air columns 212. The two vertical air columns 211 are respectively connected to the left and right edges of the screen body 10, and the two horizontal air columns 212 are respectively connected to the upper and lower edges of the screen body 10. In this way, the two vertical air columns 211 expand the screen body 10 in the vertical direction, that is, the up and down direction, and the two horizontal air columns 212 expand the screen body 10 in the horizontal direction, that is, the left and right direction. In this way, the force on the periphery of the screen body 10 is more uniform, and the screen body 10 can be expanded more flat.

[0044] Specifically, the two vertical air columns 211 are the left vertical air column 211L and the right vertical air column 211R, respectively, and the left vertical air column 211L and the right vertical air column 211R are connected to the left and right edges of the curtain body 10.

[0045] The two horizontal air columns 212 are the top horizontal air column 212T and the bottom horizontal air column 212B, respectively. The top horizontal air column 212T and the bottom horizontal air column 212B are connected to the upper and lower edges of the screen body 10, respectively. The two ends of the top horizontal air column 212T are connected to the top of the two vertical air columns 211, and the bottom horizontal air column 212B is connected to the bottom edge of the screen body 10. The two ends of the bottom horizontal air column 212B are connected to the bottom of the two vertical air columns 211. Thus, the left vertical air column 211L, the top horizontal air column 212T, the right vertical air column 211R, and the bottom horizontal air column 212B are connected in sequence to form a complete annular frame 21. After the frame 21 is inflated, the frame 21 pulls the screen body 10 from each radial direction, making the screen body 10 flatter.

[0046] In some embodiments, the left vertical air column 211L, the top horizontal air column 212T, the right vertical air column 211R, and the bottom horizontal air column 212B can be connected in sequence. In this way, only one of the left vertical air column 211L, the top horizontal air column 212T, the right vertical air column 211R, and the bottom horizontal air column 212B needs to be equipped with an air nozzle 60 to realize the inflation and deflation process of the entire frame 21, making the inflation and deflation process simpler. Please see Figure 2 In some embodiments, the inflatable frame 20 also includes a central vertical air column 211M, which extends in the vertical direction and connects to and communicates with the top horizontal air column 212T and the bottom horizontal air column 212B, and is located between the two vertical air columns 211. Through the supporting effect of the central vertical air column 211M, the probability of the curtain body 10 sagging due to its own weight can be reduced, and the flatness of the curtain body 10 can be further improved.

[0047] It is understood that in other embodiments, a central horizontal air column (not shown in the figure) may be further provided. The central horizontal air column extends in the left and right direction and connects and communicates with the left vertical air column 211L and the right vertical air column 211R, and is located between the two horizontal air columns 212. Through the supporting effect of the central horizontal air column, the probability of the curtain body 10 sagging due to its own weight can be reduced, and the flatness of the curtain body 10 can be further improved.

[0048] Please see Figure 1-2In some embodiments, the inflatable frame 20 further includes two support frames 22, namely, a left support frame 22L and a right support frame 22R. The left support frame 22L and the right support frame 22R are arranged on the left and right sides of the enclosure 21 along the left and right directions. That is, the two support frames 22 are arranged on the left and right sides of the whole formed by the two vertical air columns 211 and are respectively connected to the two vertical air columns 211 to support the two vertical air columns 211. Specifically, the left support frame 22L is connected to the left vertical air column 211L and is used to support the left vertical air column 211L, and the right support frame 22R is connected to the right vertical air column 211R and is used to support the right vertical air column 211R. By having the two support frames 22 in contact with the ground, the contact area between the inflatable curtain 1 and the ground can be increased, thereby improving the stability of the inflatable curtain 1 when it is placed vertically on the ground.

[0049] In some embodiments, each support frame 22 includes a front support air column 221, a rear support air column 222, and a bottom support air column 223. The left support frame 22L will be used as an example for illustration.

[0050] The top of the front support air column 221 is connected to the frame 21. Specifically, the front support air column 221 is connected to the left vertical air column 211L, and the front support air column 221 is located on the front side of the curtain body 10. In this way, when the wind blows from back to front onto the inflatable curtain 1, the front support air column 221 can support the inflatable curtain 1 backward, reducing the probability of the inflatable curtain 1 tilting over.

[0051] The top of the rear support air column 222 is connected to the frame 21. Specifically, the rear support air column 222 is connected to the left vertical air column 211L, and the rear support air column 222 is located on the rear side of the curtain body 10. In this way, when the wind blows from front to back onto the inflatable curtain 1, the rear support air column 222 can support the inflatable curtain 1 forward, reducing the probability of the inflatable curtain 1 tilting down one after the other.

[0052] Furthermore, the top of the rear support air column 222 is connected to the top of the front support air column 221 at an acute angle. In this way, the included angle formed by the top of the rear support air column 222 and the top of the front support air column 221 is small. When the lengths of the rear support air column 222 and the front support air column 221 are fixed, the rear support air column 222 and the front support air column 221 can be connected to a higher position of the left vertical air column 211L, thereby improving the support stability of the left vertical air column 211L and reducing the size occupied by the rear support air column 222 and the front support air column 221 in the front-back direction.

[0053] The two ends of the bottom support air column 223 are connected to the bottom ends of the front support air column 221 and the rear support air column 222, respectively. By further setting the bottom support air column 223, the contact area between the inflatable frame 20 and the ground can be further increased, thereby improving the stability and flatness of the inflatable frame 20 when it is placed vertically on the ground. In addition, the bottom support air column 223, the front support air column 221, and the rear support air column 222 form a triangular structure, which can further improve the overall structural stability of the support frame 22, thereby further improving the support stability of the support frame 22 for the vertical air column 211.

[0054] In some embodiments, the bottom support air column 223 includes a front support section 2231 and a rear support section 2232. The front end of the front support section 2231 is connected to the bottom end of the front support air column 221, and the rear end of the rear support section 2232 is connected to the bottom end of the rear support air column 222. The front end of the rear support section 2232 and the rear end of the front support section 2231 are connected at an obtuse angle. That is, the bottom end of the rear support air column 222, the rear support section 2232, the front support section 2231, and the bottom end of the front support air column 221 are connected sequentially from back to front, and the rear support section 2232 and the front support section 2231 are set at an obtuse angle.

[0055] Specifically, taking the left support frame 22L as an example, since the rear support section 2232 and the front support section 2231 are set at an obtuse angle, the rear support section 2232 extends horizontally to the left rear, and the front support section 2231 extends horizontally to the left front. In this way, when the wind blows from right to left, the rear support section 2232 and the front support section 2231 can support the rear support air column 222 and the front support air column 221 respectively, and then support the left vertical air column 211L through the rear support air column 222 and the front support air column 221, reducing the probability of the inflatable curtain 1 tilting to the left.

[0056] Similarly, when the wind blows from the right front to the left rear, the rear support section 2232 can support the rear support air column 222, which in turn supports the left vertical air column 211L, reducing the probability of the inflatable curtain 1 tilting to the left rear. When the wind blows from the right rear to the left front, the front support section 2231 can support the front support air column 221, which in turn supports the left vertical air column 211L, reducing the probability of the inflatable curtain 1 tilting to the left rear.

[0057] In some embodiments, one end of the bottom horizontal air column 212B is connected to the obtuse angle connection of one of the bottom support air columns 223, and the other end of the bottom horizontal air column 212B is connected to the obtuse angle connection of another bottom support air column 223. In this way, in the same support frame 22, the rear end of the front support section 2231, the front section of the rear support end, one end of the bottom horizontal air column 212B, and the bottom end of one of the vertical air columns 211 are connected to the same position. This can further strengthen the structural strength of the inflatable frame 20 after inflation, thereby improving the wind resistance of the inflatable curtain 1.

[0058] In some embodiments, both support frames 22 are connected to the surrounding frame 21, so that only one air nozzle 60 needs to be set in one of the support frames 22 or the surrounding frame 21 to realize the inflation and deflation process of the entire inflatable frame 20, making the inflation and deflation process simpler.

[0059] Please see Figure 3 In some embodiments, the storage bag 41 is bonded to the acute angle connection between the front support air column 221 and the rear support air column 222. In this way, the storage bag 41 is bonded to the top of both the front support air column 221 and the rear support air column 222, which can increase the bonding area between the storage bag 41 and the support frame 22 and improve the bonding stability of the storage bag 41 on the support frame 22.

[0060] Furthermore, the horizontal cross-section of the storage cavity gradually increases from top to bottom. That is, the horizontal cross-section of the storage cavity becomes larger as it approaches the bottom of the storage cavity. This allows the windproof rope 30 to be mostly located at the bottom of the storage cavity due to its own weight, enabling the storage cavity to accommodate a longer length of windproof rope 30.

[0061] Please see Figure 1-2 In some embodiments, at least two windproof ropes 30 are provided, and the at least two windproof ropes 30 are respectively connected to two vertical air columns 211. That is, at least one windproof rope 30 is connected to the left vertical air column 211L, and at least another windproof rope 30 is connected to the right vertical air column 211R. In this way, by fixing the inflatable frame 20 to the ground with at least two windproof ropes 30, the stability of the inflatable frame 20 when placed vertically on the ground can be further improved.

[0062] Please see Figure 1-2Corresponding to at least two windproof ropes 30, the number of storage bags 41 is also set to at least two. At least two storage bags 41 are respectively connected to two support frames 22. For example, two storage bags 41 are glued to the left support frame 22L and the right support frame 22R at the acute angle connection between the front support air column 221 and the rear support air column 222; or, at least two storage bags 41 are respectively connected to two vertical air columns 211. For example, at least one storage bag 41 is connected to the left vertical air column 211L to store the windproof rope 30 connected to the left vertical air column 211L, and at least another storage bag 41 is connected to the right vertical air column 211R to store the windproof rope 30 connected to the right vertical air column 211R.

[0063] Furthermore, the connection point between the windproof rope 30 and the vertical air column 211 is higher than that of the corresponding storage bag 41. Thus, the connection point between the windproof rope 30 and the vertical air column 211 is higher, and when the wind blows towards the inflatable screen 1, the windproof rope 30 can pull the inflatable screen 1 from a higher position, so that the inflatable screen 1 can withstand stronger winds and has stronger wind resistance.

[0064] Please see Figure 1 as well as Figure 3 In some embodiments, the inflatable screen 1 further includes at least two pull rings 50, which are respectively connected to two vertical air columns 211. At least one pull ring 50 is connected to the left vertical air column 211L, and at least another pull ring 50 is connected to the right vertical air column 211R. At least two windproof ropes 30 are respectively threaded through the at least two pull rings 50, that is, at least two windproof ropes 30 are respectively threaded through the pull rings 50 on the left vertical air column 211L and the right vertical air column 211R. In this way, the middle part of the windproof rope 30 is threaded through the corresponding pull ring 50, and the two free ends of the same windproof rope 30 can be fixed to the front and rear sides of the inflatable screen 1 in the front-back direction, thereby improving the stability of the inflatable screen 1 when placed vertically. When it is necessary to store the windproof rope 30, the two free ends of the same windproof rope 30 can be stored in the adjacent storage bag 41 to prevent the two free ends from swinging randomly.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
