[0001] This invention relates generally to a civil aviation technology, and more specifically, to a technology for compartmentalization within the cabin of a civil aircraft. Background Technology

[0002] Currently, due to specific modification requirements, civil aircraft need to have different cabin compartment designs. Existing aircraft generally use partitions to divide the passenger cabin or cargo hold into different functional areas. Partitions can divide the cabin interior into independent areas according to different needs and functions, providing different cabin layouts, passenger services, and cargo load configurations. Common partitions include partitions between first class and business / first class, partitions between business / first class and economy class, and partitions between economy class cabins, etc.

[0003] First-class, business-class, or executive-class cabin partitions typically integrate multiple functions, including sliding doors, storage, and entertainment facilities. They require connection to the aircraft structure via brackets or rods, making installation cumbersome and disassembly inconvenient. Economy-class cabin partitions often require connection to the aircraft's overhead bins and structure via brackets or mounting brackets. These partitions experience complex stress environments, are difficult to disassemble and reassemble, and are detrimental to line maintenance.

[0004] The aforementioned aircraft compartmentation device has many heavy and complex parts, making it inconvenient to disassemble and assemble, and thus difficult to meet the needs of rapid modification and compartmentation of aircraft cabin sections.

[0005] Therefore, it is desirable to improve the existing compartmentation devices to provide a cabin compartmentation device that can be quickly installed and removed and is reliable in use. Summary of the Invention

[0054] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0055] Figure 1 A schematic diagram is shown illustrating the use of a compartmentalization device 10 according to a preferred embodiment of the present invention in an aircraft cabin. Depending on the requirements of the aircraft cabin layout, Figure 1 As shown, three compartmentation devices 10 are installed on the bulkhead and supports on one side of the cabin interior. It should be understood that the same three compartmentation devices can be installed on the other side of the cabin, so that the compartmentation devices are arranged side by side in pairs. Each compartmentation device 10 is fitted with a curtain below it, thereby independently dividing the originally unified cabin into multiple areas.

[0056] Figure 2 A perspective view of the compartmentation device 10 according to a preferred embodiment of the present invention is shown, while Figure 3 A perspective view of the compartmentation device is shown from another angle. The compartmentation device 10 mainly includes a clamping assembly 30 for engaging with a wall panel or bracket fixed inside the cabin, a compartmentation plate body 20 connected to the clamping assembly 30, and an attachment device installed on the compartmentation plate body 20, wherein the attachment device is used to install partitions such as curtains or partitions.

[0057] Figure 5 A perspective view of a compartment panel body 20 according to a preferred embodiment of the present invention is shown. The compartment panel body 20 has a double-layer cavity structure. Preferably, the compartment panel body 20 is integrally formed from a lightweight honeycomb sandwich panel material. The compartment panel body 20 is generally elongated, with its height being less than its length. The length of the body 20 depends on the requirements of the partitioning scenario in which it is used.

[0058] Specifically, the main body 20 of the compartment panel includes a first sidewall 21 and a second sidewall 22. The first sidewall 21 and the second sidewall 22 are arranged in a substantially parallel manner to form an internal cavity.

[0059] To ensure the strength of the compartment plate body 20, the compartment plate body 20 also includes multiple reinforcing ribs 23 and 25. These reinforcing ribs 23 and 25 extend between the inner surfaces of the first side wall 21 and the second side wall 22 within the internal cavity of the compartment plate body 20, thereby dividing the internal cavity into multiple smaller cavities. Figure 4 As shown, in the internal cavity, there is at least one horizontally extending reinforcing rib 25, which extends from the left side to the right side of the compartment body 20. Above the horizontal reinforcing rib 25, there are multiple vertically arranged reinforcing ribs 23. Below the horizontal reinforcing rib 25, no reinforcing rib is formed, but a complete long space is reserved for setting up attachment devices.

[0060] The attachment of the compartmentation device 10 is preferably configured to retractably install curtains or partitions. For example... Figure 4 As shown, the attachment device includes a slide rail 51 and multiple hooks 52 mounted on the slide rail 51. Through the slide rail and sliding hook structure, a partition curtain 70 can be suspended below the compartment panel as needed. The partition curtain 70 can be retracted and fastened during aircraft flight, landing and taxiing, without affecting emergency evacuation of the cabin.

[0061] from Figure 4As can be seen in the cross-sectional view, the slide rail 51 can be made of C-shaped profile, preferably metal or rigid resin. The slide rail 51 is connected to the lower surface of the horizontal reinforcing rib 25 via Velcro, so that the groove of the slide rail 51 faces downward. Multiple hooks 52 with pulleys are slidably inserted into the slide rail 51 to hang the curtain 70. It should be understood that it is better for the groove of the slide rail 51 to face downward, so as to avoid dust accumulation in the slide rail 51 affecting the smoothness of the slide rail 51. At the same time, the entire slide rail 51 is accommodated in the space formed by the horizontal reinforcing rib 25 and the lower part of the two side plates. The slide rail 51 does not protrude from the lower edge of the main body 20, only a part of the hooks 52 protrudes from the compartment plate main body 20. On the one hand, it improves the aesthetics, and on the other hand, it protects the pulleys of the hooks 52 to reduce dust accumulation.

[0062] In other alternative embodiments, the slide rail 51 may also be connected to the compartment body 20 by other connection methods, such as fastener connection, snap-fit ​​connection or adhesive connection.

[0063] like Figure 2 As shown, each compartment panel body 20 is typically mounted to the bulkhead panel by two clamping assemblies 30. The two clamping assemblies 30 are connected to the compartment panel body 20 at a distance from each other. Preferably, the two clamping assemblies 30 are arranged separately at or near the two ends of the compartment panel body 20. The location of the clamping assemblies 30 can also be determined based on the available mounting locations on the bulkhead panels or brackets inside the cabin.

[0064] Figure 6 and Figure 7 Perspective and plan views of a preferred clip assembly 30 according to the present invention are shown respectively. The clip assembly 30 mainly includes a pair of clips 31 and a clip applying force device. Each clip 31 has a latching portion 32 at its end, and the clip applying force device includes an elastic element, such as a spring 36, disposed between the pair of clips 31, the elastic element being arranged to apply a clamping force to the pair of clips 31. Further, as... Figure 6 and Figure 7As shown, the clamping force application device includes a pin 35 and a spring 36. The pin 35 passes through a through hole 38 formed on a pair of clamps 31, while the spring 36 is sleeved on the pin 35 and arranged between the pair of clamps 31. Furthermore, the clamping force application device also includes a pin 37, which is installed at one end of the pin 35 and inserted into a radially formed insertion hole at the end of the pin 35 that passes through the through hole 38 of the clamp 31, for mounting the pin 35 onto the clamp 31. In a preferred embodiment, the insertion hole 38 for inserting the pin 35 is formed below the clamp 31, away from the latching portion 32. This way, when the clamping assembly 30 is installed with the compartment plate body 20, the clamping force application device is received within the internal cavity of the compartment plate body 20, thus preventing accidental activation of the clamping force application device.

[0065] In an alternative embodiment, the pin can be fixedly connected to one clip, and a through hole is formed on the other clip. The pin is inserted into the other through hole, and a spring is arranged between the two clips, which can also achieve the same effect of applying force to clamp the clips on both sides.

[0066] The spring 36 in the clamping force application device is in a compressed state after the clamping latch 32 is installed. Thus, the spring 36 will always apply an outward elastic force to the clamp 31, causing the two clamps 31 to tend to clamp together towards both sides of the receiving slots 62. Figure 6 and Figure 8 As shown, the latching portions 32 of the two clips 31 are U-shaped, with the openings of the U-shaped latching portions 32 facing opposite directions, i.e., towards the left and right sides of the clip assembly 30. When the clip assembly 30 is mounted on the compartment plate body 20, the openings of the latching portions 32 face the two side walls of the compartment plate, respectively. In this case, the direction of the elastic force applied by the spring 36 is substantially transverse to the extension direction of the slide rail 51.

[0067] In addition, the clip 31 is provided with a fastening part, which is located at the end away from the latching part 32. For example... Figure 8 As shown, the fastening part includes support plates 33 arranged parallel to the side walls 21 and 22 of the compartment plate body 20. Support plate nuts 34 are fixedly provided on the support plates 33. The support plate nuts 34 are typically fixed to the opposing inner sides of the two support plates 33 by rivets. Thus, with the help of screws 27 (see...) Figure 9 The compartment plate body 20 can be fastened to the clamp assembly 30 by connecting the nut 34 and the clamp nut 34. On the compartment plate body 20, the screw holes for connecting the clamp assembly 30 can be set near the vertical reinforcing rib 23. The side wall strength is relatively large at such a position, which helps to reduce the deformation of the side wall of the body 20.

[0068] In a preferred embodiment, the distance between the two side walls 21, 22 of the compartment body 20 should be selected to ensure that the latching part 32 is tightly engaged in the corresponding slot 62. After the side walls 21, 22 of the compartment body 20 are fixed to the support plate 33 of the two clips 31 of the clip assembly 30 by the cooperation of fasteners and support plate nuts 34, the distance between the clips 31 is fixed and they can no longer move closer to each other to allow the latching part 32 to disengage from the slot 62.

[0069] On the other hand, the compartmentation device 10 may also include a mounting rail 61 for having multiple slots 62, such as Figure 10 As shown, the snap-fit ​​portion 32 of the snap-fit ​​assembly can engage with these slots 62. The distance between adjacent slots 62 corresponds to the distance between the side walls of the compartment panel body 20, ensuring that the snap-fit ​​portion 32 on the clip 31 can clamp onto one edge of the slot 62 when the elastic force in the clip assembly 30 is applied. The mounting rail 61 can be pre-set at the location in the cabin where the compartment panel 10 needs to be installed. However, in some embodiments, the slots 62 can be pre-set directly on the cabin wall panel or bracket.

[0070] The following describes the installation process of the compartment device 10 according to a preferred embodiment of the present invention.

[0071] Before installation, the clip assembly 30 and the compartment plate body 20 are separate from each other, while the attachment devices, including the slide rail 51 and hook 52, are pre-installed with the compartment plate body 20, and the support plate nut 34 is fixed to the support plate 33 by rivets. Align the latching parts 32 of the two clips 31 in the clip assembly 30 with the selected slots 62, and slightly press the two clips 31 inward against the elastic force of the spring 36, so that the latching parts 32 engage with the slots 62. After releasing, the latching parts 32 of the two clips 31 respectively hook outward to the two sides of the slots 62, thus completing the quick connection of the clip assembly 30. Next, insert the compartment panel body 20 and the clamping assembly 30 together from bottom to top. Insert the support plate 33 with nut 34 from the clamping assembly 30 into the internal cavity through the top opening of the compartment panel body 20, aligning it with the screw holes on the side wall of the body. Then, securely connect the compartment panel body 20 to the clamping assembly 30 with screws 27, thus completing the installation of the entire compartment device 10. Finally, hang the curtain 70 on the hook 52 to complete the compartment arrangement.

[0072] The disassembly of the compartmentation device 10 can be performed in the reverse order described above. Typically, the partition curtain 70 is removed first, then the screws 27 are loosened, the compartmentation plate body 20 is removed from the clip assembly 30, and then the two clips 31 of the clip assembly 30 are pressed inward against the elastic force of the spring to remove the clip assembly 30.

[0073] Preferably, the main body 20 of the compartment panel and the clip assembly 30 are painted to make them consistent with the overall color scheme of the cabin.

[0074] Furthermore, preferably, such as Figure 2 As shown, a hook portion 26 is integrally formed at the lateral end of the compartment panel body 20 for securing the curtain 70 in the center of the aisle. In an alternative embodiment, the hook portion 26 can be a hook located at the end of the slide rail 51, which is fixed relative to the slide rail 51 and cannot slide. In other alternative embodiments, the size and material of the clamp 31 in the clamping force application device are selected so that it is elastically deformable when the clamp assembly is installed on the compartment panel body, and the clamping force application device can be located near the buckle portion 32. With this alternative embodiment, after the clamp assembly 30 is fixed to the compartment panel body 20, the clamp assembly 30 can be installed into the slot 62 of the track 61. Correspondingly, when disassembling the compartment device, the clamp assembly 30 can be directly squeezed inward to remove it from the slot 62 without first separating the body from the clamp assembly. This compartment device is easier and faster to install and is more suitable for situations where relatively lightweight partitions are suspended.

[0075] In other alternative embodiments, the clip assembly 30 is also connected to the compartment body 20 via other quick-release structures, such as by a plug-in mechanism.

[0076] The compartmentation device 10 according to the present invention can flexibly arrange the curtains at the required locations according to the cabin layout requirements, and the clip assembly 30 can be quickly installed onto the cabin wall panel or bracket using elastic elements, realizing the modular installation of the cabin compartmentation facilities.

[0077] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the invention, fall within the protection scope defined by the claims of the present invention.
