Description

Technical Field

[0001] This utility model relates to a barrier rope assembly. Background Technology

[0002] When an aircraft is parked with its doors open and boarding stairs and jet bridges not yet connected, passengers near the doors (such as flight attendants and cleaning staff) may not notice the edge of the cabin and could fall, resulting in personal injury. Therefore, safety ropes are typically installed on the door frames of aircraft boarding doors and service doors. These ropes are extended and hooked onto hooks on the opposite side of the frame to secure the door, alerting passengers that the door is open and preventing falls in case of an accident.

[0003] Currently, the arresting rope is directly installed to the door frame of the aforementioned hatch using fasteners consisting of bolts and nuts. Specifically, one end of the arresting rope is fixed to a side of the door frame from the side opposite to the hatch opening with bolts, and then tightened with nuts from the hatch opening side of that side frame. However, near the door frame where the arresting rope is installed, there are often onboard facilities such as galleys and lavatories. Therefore, when the arresting rope is damaged and needs to be replaced, it is difficult for operators to bypass the equipment near the door frame to remove and install the arresting rope. To facilitate the replacement, space needs to be reserved near the onboard equipment for access to the arresting rope, or some onboard equipment needs to be temporarily removed, making the arresting rope replacement operation quite complicated. Utility Model Content

[0004] This utility model was made in view of the above-mentioned problems, and its purpose is to provide a barrier rope assembly that can be detached from one side.

[0005] To achieve the above objectives, this utility model provides an arresting rope assembly disposed on a door frame of an aircraft having opposing first and second side frames. The arresting rope assembly includes: an arresting rope supported at one end on the first side frame; and a hook mounted on the second side frame for hooking the other end of the arresting rope when pulled from the first side frame toward the second side frame. The arresting rope assembly includes: a support member located on the side of the first side frame opposite to the second side frame and supporting the one end of the arresting rope; and a connector that connects the support member to the first side frame in a manner that allows for detachment and reattachment from the second side frame relative to the first side frame.

[0006] According to the arresting rope assembly of this utility model, for a hatch that requires the installation of an arresting rope, a support member for supporting one end of the arresting rope is provided on one of the two side frames opposite to the hatch frame opening, on the side opposite to the other side frame, i.e., the side opposite to the opening. This support member is connected to the side frame via a connector that can be detached from the side where the opening is located. Therefore, when replacing the arresting rope installed around the hatch, the support member can be removed from or installed onto the hatch frame by removing or installing the connector from the more convenient opening side. This allows for arresting rope replacement without removing other equipment around the hatch or reserving space for fastener installation around the arresting rope installation location.

[0007] Furthermore, in the barrier rope assembly of this utility model, preferably, the support member includes: a bracket that supports one end of the barrier rope; and a pad that is detachably connected to the bracket and located between the bracket and the first frame, wherein the first connector connects the support member to the first frame via the pad.

[0008] Furthermore, in the barrier rope assembly of this utility model, it is preferable that at the connection between the pad and the first frame, the surface of the pad is formed with a shape corresponding to the surface of the first frame.

[0009] According to the above-described barrier rope assembly, the support member includes a bracket for supporting the barrier rope and a pad for transferring the bracket to the frame, thereby connecting the barrier rope to the frame via the pad. Furthermore, by forming the surface of the pad at the connection point with the frame into a shape corresponding to the surface of the frame, the shape of the pad can be designed according to the specific shape of different parts of the frame surface. This allows for the specific selection of the installation position relative to the door frame based on actual conditions, increasing the spatial freedom of barrier rope installation.

[0010] Furthermore, in the barrier rope assembly of this utility model, it is preferred that the bracket includes a winding member capable of winding up the barrier rope.

[0011] Furthermore, in the barrier rope assembly of this utility model, it is preferred that it also includes a support and a baffle. The support is disposed on the first frame and supports the baffle. The baffle is provided with an opening, which allows the barrier rope to pass through and prevents the barrier rope from being completely wound into the winding member.

[0012] According to the above-described barrier rope assembly, after the barrier rope is used, it can be wound up by the winding mechanism. Furthermore, by setting up a baffle, the barrier rope is prevented from being completely wound up to a position that is inconvenient for the operator to grasp, making it convenient for the operator to frequently pull out the barrier rope.

[0013] Furthermore, in the barrier rope assembly of this utility model, it is preferred to include a pin, which is supported on the support. When the barrier rope is pulled out, the pin can support the barrier rope in a manner that prevents the barrier rope from contacting the first frame.

[0014] According to the above-described structure of the barrier rope assembly, the barrier rope, after being pulled out, does not come into contact with the door frame through the pin supported on the support. Thus, the door frame can be prevented from scraping the barrier rope and causing wear during the pulling process, thereby improving the durability of the barrier rope.

[0015] Furthermore, in the barrier rope assembly of this utility model, preferably, the first connecting member is a bolt, and the nut is disposed on the support member in a manner that restricts rotation, and the support member is connected to the first frame by the bolt and the nut.

[0016] Furthermore, in the arresting rope assembly of this invention, it is preferable that the first frame and the second frame are opposite each other in the length direction of the aircraft fuselage.

[0017] The arresting rope assembly with the above structure can be installed in a way that allows for single-sided installation and removal from the door frame opening side, and can be installed along the length of the fuselage at the cabin door located on the side of the fuselage to warn the personnel on board.

[0018] (Utility Model Effect)

[0019] According to the arresting rope assembly of this utility model, for aircraft doors requiring arresting rope installation, the arresting rope is supported by a support member, and the support member is installed to the door frame from the opposite side of the opening using a connector. Therefore, compared to directly installing the arresting rope to the door frame from the opposite side of the opening using fasteners, when disassembling and replacing the arresting rope, the support member supporting the arresting rope can be disassembled and reassembled from the opening side using the connector, thus completing the replacement of the arresting rope without having to remove other onboard equipment around the door to access the arresting rope, simplifying the operation process. Simultaneously, there is no need to reserve space for fastener installation and disassembly on the installation side of the arresting rope; only space for the rope's movement is required, increasing the spatial freedom of the onboard equipment arrangement around the door. Furthermore, by using the support member as a transition module, the contact surface requirements for the arresting rope connection to the frame are reduced, increasing the spatial freedom of the arresting rope's arrangement.

[0045] The following description, in conjunction with the accompanying drawings, describes one embodiment of the present invention.

[0046] Figure 1This is a schematic diagram of a door frame equipped with the arresting rope assembly of this embodiment. In this embodiment, the door frame is, for example, the door frame of a door located on the side of the fuselage, such as an aircraft boarding door, and includes two opposing side frames along the length of the fuselage. Specifically, the door frame includes a front side frame 9 located on the nose side and a rear side frame 8 located on the tail side, with the front side frame 9 and the rear side frame 8 facing each other across a door frame opening.

[0047] In addition, such as Figure 2 , Figure 3 As shown, in this embodiment, the barrier rope assembly includes a barrier rope 1 mounted on the rear frame 8 and a hook 7 mounted on the front frame 9.

[0048] In the following description, the side of the rear frame 8 that is closer to the door frame opening is referred to as the opening side, and the side opposite to the opening side (i.e., the side used to install the barrier rope 1) is referred to as the installation side.

[0049] The barrier rope assembly in this embodiment mainly includes a barrier rope 1, a support 3, a hook 7, a pad assembly 12, a bolt 16, and a retractor 17.

[0050] The barrier rope 1 is secured to the rear frame 8 via a retractor 17 and a pad assembly 12. (Example) Figure 4 As shown, the pad assembly 12 of this embodiment includes a pad 2, a bushing 14, and a support plate nut 15.

[0051] like Figure 5 As shown, the pad 2 of this embodiment includes a base and four protrusions. When viewed along the thickness direction of the pad 2, the base is formed as a rounded rectangle with rounded corners at all four corners. The four protrusions extend upward from the upper surface of the base at the four corners, and when viewed along the thickness direction of the pad 2, the inner corner of each protrusion along the diagonal of the base is rounded. Furthermore, multiple ( ) are formed in the portion of the base other than the protrusions. Figure 5 There are four through holes (four in total) for the bolts 16 described later to pass through. Additionally, although... Figure 5 Not shown in the diagram, but the seat also has multiple through holes for rivets to pass through.

[0052] Holes for mounting the bushing 14 are formed on each boss portion of the pad 2. The bushing 14 is made of, for example, a material with good wear resistance, such as... Figure 6 As shown, the bushing 14 is cylindrical, and its inner wall has threads that mate with the screw 13 described later. In this embodiment, four bushings 14 are provided on the pad assembly 12. The outer diameter of the bushing 14 is set to be slightly larger than the size of the hole formed on the boss portion of the pad 2, and the four bushings 14 are pressed into the holes on the four boss portions respectively. Thus, the bushing 14 is fixedly connected to the pad 2 by the interference fit between the bushing 14 and the hole.

[0053] The support plate nut 15 of this embodiment includes a nut body and a support plate fixed to the nut body. The nut body is formed into a square body with a threaded hole in the center that mates with the bolt 16 described later. The support plate is formed into an ear shape and is fixed to the bottom of the nut body from both sides, and has through holes for rivets to pass through.

[0054] In this embodiment, four support plate nuts 15 are provided on the pad assembly 12. The threaded holes on the nut body of the support plate nut 15 are aligned with the through holes on the seat of the pad 2 for the bolts 16 to pass through. The support plate of the support plate nut 15 is riveted to the pad 2 by rivets, thereby fastening the support plate nut 15 to the pad 2.

[0055] The arresting rope 1 is made of high-strength nylon webbing, has a certain degree of elasticity, and is long enough to be pulled from the rear frame 8 to the front frame 9 of the aircraft door. It features conspicuous patterns such as yellow and black stripes to ensure visibility by personnel under various lighting conditions. Furthermore, although not shown, one end of the arresting rope 1 has a loop made of nylon webbing or rope. When the door is opened, the operator pulls the arresting rope 1 and attaches the loop to the hook 7, thus positioning the arresting rope 1 between the rear frame 8 and the front frame 9 for a warning effect.

[0056] like Figure 7 As shown, in this embodiment, the barrier rope 1 is designed to be retractable and supported by a retractor 17 (equivalent to the bracket of this utility model), and the barrier rope 1 is stored in the retractor 17 when not in use. Specifically, the retractor 17 includes a housing and an inertia wheel axle. The housing is used to house the barrier rope 1 and support the inertia wheel axle, and multiple through holes are formed at the bottom of the housing for the threaded portions of the screws 13 to pass through. The inertia wheel axle is used to retract the barrier rope 1, and it is connected to the end of the barrier rope 1 that is not provided with a loop buckle. After the barrier rope 1 is used, it can automatically retract the barrier rope 1 into the retractor 17 by inertia.

[0057] The barrier rope 1 is securely connected to the pad assembly 12 via a retractor 17. Specifically, as follows: Figure 7 As shown, the bottom of the housing of the retractor 17 abuts against the upper end face of the boss portion of the pad 2, and the hole formed on the bottom of the housing is aligned with the holes of the four bushings 14. Multiple screws 13 pass through the through holes on the bottom of the housing and are screwed into the four bushings 14 of the pad assembly 12. Thus, the barrier rope 1 is fixedly connected to the pad assembly 12 via the retractor 17, forming a barrier rope-pad assembly (hereinafter sometimes referred to as an assembly).

[0058] In this embodiment, when installing the assembly to the rear frame 8, the assembly is first abutted against the rear frame 8 from the mounting side. Specifically, the bottom surface of the pad 2 in the assembly abuts against the surface of the mounting side of the rear frame 8. Then, four bolts 16 are passed through the rear frame 8 from the opening side and fitted to the four support nuts 15 provided on the pad assembly 12. Thus, the assembly is fixedly installed to the rear frame 8, completing the installation of the barrier rope 1. Here, the assembly is located between the skin 10 and the onboard equipment 11 in the direction facing the door frame opening, and the connection and installation position of the assembly relative to the rear frame 8 can be specifically selected according to the actual situation.

[0059] Furthermore, in this embodiment, such as Figure 2 As shown, the surface at the connection between the rear frame 8 and the assembly is flat. However, depending on the actual installation situation, the surface of the door frame at the suitable location for installing the assembly may also be stepped or otherwise non-flat. Therefore, the connection surface of the pad 2 can be designed according to the actual shape of the door frame connection surface to achieve contact connection with the connection surfaces of various door frame edges.

[0060] like Figure 2 As shown, a support 3 is also provided at the rear frame 8. The support 3 is made of, for example, a high-strength metal material and includes a fixing part and a supporting part.

[0061] The fixing part is fixedly connected to the rear frame 8 from the opening side by fasteners, and has a portion that extends toward the mounting side without contacting the rear frame 8. A pair of lugs are provided on this portion, extending toward the mounting side, and through holes are formed at the ends of the lugs on the mounting side. The pin 4 passes through the through holes on the pair of lugs, and the two ends of the pin 4 are fixed by two cotter pins 5, thereby mounting the pin 4 between the pair of lugs.

[0062] The support portion is formed to extend from the end of the fixed portion near the cabin interior side toward the opening side, and a baffle 6 is provided at its opening side end. The baffle 6 is made of, for example, a plastic with high wear resistance, and an opening is formed on the baffle 6 to allow the arresting rope 1 to pass through.

[0063] Therefore, with the hatch open, the operator grasps the loop at the free end of arresting rope 1 to pull it out. The pulled-out arresting rope 1 first passes around the pin 4 on the support 3 from the mounting side, then is pulled towards the opening side and passes through the opening on the baffle 6. The pulling continues until the loop can be hooked onto the hook 7 on the front frame 9, thus completing the setup of the arresting rope 1 and serving as a warning to the personnel on board. Here, because the arresting rope 1 first passes around the pin 4 towards the mounting side and then turns to pass through the baffle 6, its surface remains a certain distance from the rear frame 8 when taut. Therefore, during the pulling process, the surface of the arresting rope 1 will not contact the rear frame 8 and cause friction, reducing wear on the arresting rope 1 and improving its durability.

[0064] Furthermore, preferably, the barrier rope 1, after passing through the opening on the baffle 6 and without being pulled, will not be completely retracted into the retractor 17, and the loop of the barrier rope 1 is located on the opening side relative to the baffle 6. Specifically, for example, a limiting member is provided at the connection between the barrier rope 1 and the loop, the limiting member being configured to deform under pressure and pass through the opening on the baffle 6, and to be unable to pass through the opening when there is no pressure or the pressure is small. Alternatively, the limiting member may not be deformable, but the opening on the baffle 6 may be deformable and enlarged under pressure to allow the limiting member to pass through, and to prevent the limiting member from passing through when there is no pressure or the pressure is small. Additionally, both the limiting member and the opening on the baffle 6 may be deformable.

[0065] In this way, the barrier rope 1 will not be completely retracted into the retractor 17 when it is not pulled. Instead, it will be kept in the state where the ring buckle is on the open side relative to the baffle 6 by the limiting member. This makes it convenient for the operator on the machine to pull the barrier rope 1.

[0066] In addition, preferably, the edges of the openings on the baffle 6 are rounded to reduce wear on the barrier rope 1 when it is pulled, thereby improving the durability of the barrier rope 1.

[0067] The following describes the installation, replacement, and usage methods of the barrier rope assembly in this embodiment.

[0068] The barrier rope assembly of this embodiment mainly includes a pad assembly 12 for installing the barrier rope 1, a retractor 17, and a hook 7 for hooking the barrier rope 1.

[0069] One end of the barrier rope 1 has a loop for hooking onto the hook 7, and the other end of the barrier rope 1 is connected to the inertia wheel axle of the reel 17 and wound onto the inertia wheel axle.

[0070] The bushing 14 with threads formed on its inner wall is installed to the pad 2 by interference fit, and the support plate nut 15 is installed to the pad 2 by riveting, thereby completing the preparation of the pad assembly 12.

[0071] Next, align the through holes at the bottom of the housing of the retractor 17 with the openings of the bushings 14 on the pad assembly 12, and screw the screws 13 into the threads on the inner wall of the bushings 14, thereby connecting the barrier rope 1 to the pad assembly 12 via the retractor 17 to form an assembly.

[0072] The operator can hold the assembly and pass it from the maintenance access cover of the onboard equipment 11 to the mounting side surface of the rear frame 8. Here, an opening for bolt 16 installation is pre-drilled on the rear frame 8 at a suitable location for installing the barrier rope 1 (e.g., at a height suitable for warning personnel on board), corresponding to the layout of the support plate nut 15 on the pad assembly 12. After aligning the threaded hole of the support plate nut 15 with the opening on the rear frame 8, the bolt 16 is screwed into the threaded hole of the support plate nut 15 from the open side. Thus, the assembly is installed to the rear frame 8 from the mounting side, i.e., the barrier rope 1 is installed to the rear frame 8. Here, the hook 7 is installed on the front frame 9 corresponding to the mounting position of the barrier rope 1.

[0073] When replacing the barrier rope 1, the assembly is removed by unscrewing the bolt 16 from the open side and taken out from the maintenance port cover of the machine equipment 11. After replacing the barrier rope 1, it can be installed again through the above installation process.

[0074] In addition, the support 3 can be installed from the open side to the rear frame 8. The support 3 is equipped with a pin 4 and a baffle 6 with an opening. A space is reserved between the machine equipment 11 and the rear frame 8 for the barrier rope 1 to be pulled out. After the barrier rope 1 is pulled out from the retractor 17, it first passes around the pin 4 from the installation side and then passes through the opening on the baffle 6. The ring buckle at least one end of the barrier rope 1 is kept on the open side of the baffle 6 by the limiting member set on the barrier rope 1. When the operator sets up the barrier rope 1, the barrier rope 1 can be pulled out by holding the ring buckle and pulled until the ring buckle hooks onto the hook 7. After use, the ring buckle is removed from the hook 7, and the barrier rope 1 is automatically wound up by the inertial wheel until the limiting member locks it onto the baffle 6.

[0075] (Main effects of this implementation method)

[0076] According to the arresting rope assembly of this embodiment, the arresting rope 1 is supported by a retractor 17 with an inertial pulley axle. The pad assembly 12 is connected to the retractor 17 supporting the arresting rope 1 to form an assembly. The assembly is then installed to the mounting side of the rear frame 8 from the opening side using bolts 16. Therefore, when replacing the arresting rope 1, compared to directly installing the arresting rope 1 to the door frame from the mounting side using fasteners, the assembly can be removed and the arresting rope 1 replaced by removing the bolts 16 from the opening side, without having to remove other equipment around the door, such as onboard equipment 11, to access the arresting rope 1, thus simplifying the operation process. At the same time, only space needs to be left near the mounting side of the rear frame 8 for the rope 1 to move, without having to reserve space for fastener installation and removal, increasing the spatial freedom of the arrangement of equipment such as onboard equipment 11 around the door. In addition, by using the pad 2 to transfer the retractor 17 supporting the barrier rope 1 to the frame, the contact surface shape of the pad 2 can be designed according to the actual contact surface of the frame, so as to achieve contact connection with the frame connection surface of various door frames, reduce the contact surface requirements of the barrier rope 1 to the frame, and increase the spatial position freedom of the barrier rope 1.

[0077] (Modified Example)

[0078] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0079] In the above embodiment, the example described is that the barrier rope 1 is designed as a retractable type and automatically retracts to the retractor 17 via an inertial wheel axle supported on the housing after use, but it is not limited to this. For example, the retractor 17 may not be provided, and one end of the barrier rope 1 may be directly supported by a simple bracket. After the barrier rope 1 is removed from the hook 7 after use, the part of the barrier rope 1 that passes through the baffle 6 (i.e., the part erected between the front and rear door frames) can be pulled back under the gravity of the part of the barrier rope 1 located on the installation side relative to the baffle 6, or it can be manually reset by the operator on the machine.

[0080] Furthermore, in the above embodiment, the example described is that the retractor 17 is connected by installing a bushing 14 on the pad 2 to engage with the screw 13, and by installing a support nut 15 on the pad 2 to engage with the bolt 16. However, this is not a limitation; the pad 2 may not be equipped with the aforementioned bushing 14 or support nut 15. For example, the pad 2 may be pre-formed with threaded holes for engaging with the screw 13 and bolt 16, respectively, and the retractor 17 can be installed to the rear frame 8 via the pad 2 by connecting the screw 13 and bolt 16 to the respective threaded holes.

[0081] Furthermore, in the above embodiment, the example given is that the arresting rope 1 is installed on the rear frame 8 and the hook 7 is installed on the front frame 9, but this is not a limitation. The frame on which the arresting rope 1 and the hook 7 are installed can be selected according to the installation situation of the onboard equipment around the cabin door, or the arresting rope 1 can be installed on the front frame 9 and the hook 7 can be installed on the rear frame 8.

[0082] Furthermore, in the above embodiment, the example described is the front and rear frames along the fuselage length direction on which the arresting rope assembly is installed on the door frame, but this is not a limitation. The arresting rope assembly can also be installed on two opposing frames along the fuselage width direction, height direction, etc., for example, on the door frame of doors such as aircraft lavatory doors and cockpit doors, serving to warn unauthorized personnel not to enter.

[0083] It should be understood that within the scope of this invention, the various parts of the embodiments can be freely combined, or the various parts of the embodiments can be appropriately modified or omitted.
