Description

Technical Field

[0001] This utility model relates to the technical field of air traffic control facilities, and specifically provides an airport tower control seat chair. Background Technology

[0002] In air traffic control, tower controllers need to continuously monitor runways, taxiways, and aircraft flight dynamics during critical phases such as the first and fifth turns of a flight, for extended periods of time with high concentration. To alleviate work fatigue and ensure optimal performance, they are typically equipped with dedicated chairs. The design of these chairs directly affects the controllers' comfort, work efficiency, and ultimately, the efficiency and safety of air operations.

[0003] Currently, traditional tower control chairs have significant shortcomings. Firstly, the seat height is mostly fixed, making it impossible to flexibly adjust to each controller's height, posture, and specific observation angle. When seated, controllers may experience limited visibility due to seats that are too high or too low, creating blind spots in critical areas and posing a potential threat to operational safety. Secondly, in traditional designs, the work surface and seat are usually separate facilities. This separation results in necessary equipment such as monitors, keyboards, progress sheets, and navigation data being scattered and cluttered. When the seat height is set too high, controllers must frequently bend over or significantly adjust their posture to retrieve various documents during their duties. This repetitive and unnecessary change of posture not only exacerbates physical fatigue but also introduces operational delays, potentially affecting the timeliness of decision-making and instruction issuance in the fast-paced world of air traffic control.

[0004] Therefore, there is an urgent need for a new type of tower control seat chair with a highly adjustable and integrated design to solve the above problems and provide controllers with an efficient, comfortable and safe working environment with unobstructed vision and easy access to equipment. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a novel, height-adjustable, integrated control tower chair, offering controllers an efficient, comfortable, and safe working environment with unobstructed visibility and easy access to equipment. The specific technical solution is as follows:

[0006] An airport tower control seat includes a base frame and a seat body mounted on the base frame. The front of the seat body is provided with a control table for placing items. A lifting part is provided between the base frame and the seat body. A tabletop fixing part is provided on one side of the seat body. One side of the control table is horizontally rotatably mounted on the tabletop fixing part. By rotating, the control table can be positioned in a first position in front of the seat body and a second position on one side of the seat body.

[0007] In this design, controllers can adjust the height of their seats using a lift mechanism, allowing different controllers to choose a height that suits their individual needs and preferences, thus reducing obstructed views. A control desk is also installed on the seat, providing space for essential equipment such as keyboards, progress reports, and navigation data. The desk's height adjusts with the seat height, ensuring controllers can easily access all devices without bending over or making significant adjustments to their posture. This improves both controller comfort and processing speed. While the desk's position in front of the seat can sometimes hinder controllers from getting in and out, allowing one side of the desk to rotate horizontally with the seat eliminates this interference in the second position. Once seated, rotating the desk to the first position ensures all devices are within easy reach.

[0008] Preferably, the desktop fixing part includes a vertically arranged support rod, which is fixedly arranged on one side of the seat body. The end of the support rod is provided with a pivot for connecting to the control table, and a damping mechanism is provided between the pivot and the control table.

[0009] In this solution, the damping mechanism ensures that the table rotates smoothly, quietly, and without impact, avoiding equipment damage or noise interference caused by sudden swinging. Control personnel can easily turn the table open, get up and sit down without any hindrance, thus improving the service life of the equipment and the user experience.

[0010] Preferably, the support rod is provided with a rotating collar, which is rotatably sleeved on the support rod around the axis of the support rod, and the rotating collar is connected to a display bracket.

[0011] In this solution, the monitor bracket, which is set by rotating the collar, allows the most frequently used computer monitor to be placed on the seat chair, making it easier to observe at a closer distance and reducing identification errors and the frequency of controllers turning around to observe. At the same time, the monitor can rotate flexibly around the axis of the support rod, ensuring that controllers can adjust the monitor to the most comfortable viewing angle according to their personal habits and lighting conditions, reducing visual fatigue caused by screen reflections or poor viewing angles.

[0012] Preferably, the seat body includes a seat cushion, a backrest, and armrests on both sides of the seat cushion. The height of the armrests is flush with the bottom surface of the control table. An auxiliary support plate is rotatably provided at the armrest away from the fixed part of the tabletop. The auxiliary support plate can rotate in the vertical direction. The rotation angle of the auxiliary support plate is 180°. When the auxiliary support plate is in an extreme position, the auxiliary support plate abuts against the bottom surface of the control table in the first position.

[0013] In this solution, since supervisors need to operate a mouse, the height of the armrests is adapted to the height of the control table, so that the supervisors' arms can rest on the armrests when operating the mouse, thus improving the supervisors' work comfort.

[0014] Preferably, a connector is provided at the end of the armrest away from the desktop fixing part, the connector being used to fix the control table in the first position. This prevents the control table from rotating under force when the operator's hands are resting on it.

[0015] Preferably, multiple auxiliary support legs are provided around the lifting part. The auxiliary support legs include a bottom support rod and a top support rod. The bottom end of the bottom support rod is fixedly connected to the base frame, and the top end of the top support rod is fixedly connected to the bottom of the seat body. The top support rod is slidably inserted into the bottom support rod.

[0016] In this design, when the seat body is subjected to uneven force and tends to tilt, the seat body is stabilized by the friction limit between the outer wall of the top support rod and the hole wall of the bottom support rod, thereby ensuring the stability of the seat body.

[0017] Since the height of the seat body after adjustment may be too high, making it inconvenient for controllers to get on and off the seat, in order to improve this problem, it is preferable to also include a foot pedal set on the base frame. The foot pedal includes one or more step plates, which are horizontally set in the base frame. The foot pedal also includes an anti-slip foot pedal set above the step plates, which is set in the base frame through a sliding mechanism.

[0018] In this solution, the step board provides steps for controllers to get up and down the main body of the seat, and the non-slip foot pedal meets the leg support needs of controllers in different sitting positions, ensuring that the calves and feet are effectively supported and avoiding leg soreness and numbness caused by prolonged sitting.

[0019] Preferably, the sliding mechanism includes a slide rail disposed in the base frame, and the anti-slip foot pedal is slidably disposed on both sides in the slide rail, allowing the anti-slip foot pedal to move horizontally along the front and rear directions of the seat body. The fore-and-aft distance of the anti-slip foot pedal can be finely adjusted according to the seat position to ensure operator comfort.

[0020] Preferably, the footrest is located on the base frame on the opposite side of the desktop fixing part.

[0021] Preferably, the base frame has multiple legs on its bottom surface, and each leg has a support pad that contacts the ground. This prevents the seat from accidentally moving or sliding in a control tower environment.

[0022] The beneficial effects of this utility model are:

[0023] 1. This utility model allows control personnel to adjust the height of the seat body by means of the lifting part while sitting in the seat chair, and adjust the height of the seat body to suit their own height, habits, etc., thereby reducing the obstruction of the field of vision.

[0024] 2. A control desk is installed on the seat, which can be used to place necessary equipment such as keyboards, progress sheets, and navigation data. At the same time, the height of the control desk can be adjusted with the height of the main body of the seat, ensuring that the controllers can operate the various devices on the control desk at their fingertips without having to bend over or make large adjustments to their sitting posture to operate the devices. This improves the controllers' work comfort while ensuring their processing speed. Attached Figure Description

Detailed Implementation

[0033] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of this utility model.

[0034] Example 1:

[0035] like Figure 1 and Figure 2 The diagram shows an airport tower control seat chair, comprising a base frame 1 and a seat body 2 mounted on the base frame 1. A control table 3 for placing items is located on the front of the seat body 2. The seat body 2 is positioned above the base frame 1 via a lifting mechanism 5. The seat body 2 uses a high-strength metal frame structure with a rust-proof surface to adapt to the control tower environment. It is equipped with a seat cushion 21, a backrest 22, and armrests 23 on both sides of the seat cushion 21, all with leather surfaces. The seat cushion 21 is 4-5cm thick, conforming to human body pressure distribution requirements and effectively preventing excessive pressure on the ischial tuberosity area. The backrest 22 integrates an adjustable lumbar support device, the maximum protrusion of which is located in the mid-lumbar region (approximately 200mm from the surface of the seat cushion 21), adaptively adjusting to the user's body shape to provide precise lumbar support. The armrests 23 are 25-30cm above the seat surface, and their height is flush with the bottom of the control table 3, conforming to the arm placement angle in a natural sitting posture.

[0036] Meanwhile, the control table 3 is mounted on one side of the seat body 2 via a desktop fixing part 4. Specifically, the desktop fixing part 4 includes a vertically arranged support rod 41, which is fixedly mounted on the seat body 2. A pivot 42 is provided at the end of the support rod 41, and one side of the control table 3 is horizontally rotatably connected to the support rod 41 via this pivot 42. To achieve smooth and quiet rotation and appropriate resistance at any position, a damping mechanism, such as a rotary damper or a damping hinge, is provided between the pivot 42 and the control table 3. A reinforcing plate 33 is provided at the bottom of the control table 3, and the reinforcing plate 33 is fixedly connected to the pivot 42 on the support rod 41, improving the strength of the control table 3. By rotating, the control table 3 can switch between a first working position located directly in front of the seat body 2 and a second entry / exit position located on the side of the seat. By allowing one side of the control table 3 to rotate horizontally relative to the seat body 2, in the second position, the interference of the control table 3 on the controller getting on and off the seat can be eliminated; after the controller sits on the seat, rotating the control table 3 to the first position can ensure that all the equipment on the control table 3 is in a position that the controller can operate at his / her convenience.

[0037] Furthermore, to ensure the stability of the control table 3 in the working position, a connector 24 is provided at the end of the armrest 23 away from the tabletop fixing part 4. The connector 24 can be a slot provided on the armrest 23 and a plug provided on the control table 3, or a structure with matching holes provided on the armrest and the control table 3, and fixed by a pin. In this embodiment, the connector 24 includes magnetic blocks respectively fixedly provided at the end of the armrest 23 and on the bottom surface of the corresponding side of the control table 3. When the control table 3 is rotated to the first position, the magnetic blocks on both sides attract each other, reliably fixing the tabletop and effectively preventing the control table 3 from rotating accidentally when the operator's hands are resting on it.

[0038] In this embodiment, controllers can adjust the height of the seat body 2 by using the lifting part 5 while sitting in the chair. This allows different controllers to adjust the height of the seat body 2 to suit their own height and habits, thereby reducing obstruction of vision. At the same time, a control table 3 is set on the seat, which can be used to place necessary equipment such as keyboards, progress sheets, and navigation data. The height of the control table 3 can change with the height of the seat body 2, ensuring that controllers can easily operate the various devices on the control table 3 without having to bend over or make large adjustments to their sitting posture to operate the devices. This improves the comfort of controllers and ensures the speed of processing control tasks.

[0039] Example 2:

[0040] To ensure cleanliness and efficiency during operation, the desktop of the control desk 3 is functionally divided into sections. In this embodiment, the view is taken from the perspective of the control personnel sitting in their chairs. Figure 4 As shown, the left side of the control table 3 integrates a navigation information board placement box 31, preferably 260mm × 420mm in size, to accommodate standard navigation information boards. The box features a semi-open design, with the height of the four edges preferably less than 20mm, and a dividing strip in the middle for easy and quick access to the information board. The right side of the desktop has a non-slip mouse pad area 32 with a slightly textured surface to enhance operational stability. A fixed cup holder is also installed on the side of the desktop to securely hold water cups and prevent accidental spills.

[0041] Example 3:

[0042] This embodiment, based on Embodiment 1, allows the display to be mounted on the control table 3 to further optimize human-computer interaction. For example, Figures 1 to 3As shown, a rotating collar 43 is also fitted onto the support rod 41. An additional rotation damper can be installed between the rotating collar 43 and the support rod 41 to ensure smooth rotation and allow for suspension. A monitor bracket 44 is connected to the rotating collar 43. This bracket employs a multi-joint adjustable structure, is fixed to the upper part of the support rod 41, and is located above the operating platform of the control table 3. It allows for adjustment of the monitor height by ±15cm and the tilt angle by ±30° to accommodate the visual needs of operators of different heights and reduce visual fatigue caused by screen glare or poor viewing angles.

[0043] Meanwhile, in order to improve the strength of the control table 3 and prevent damage to the connection between the control table 3 and the tabletop fixing part 4 during use, such as Figures 2 to 4 As shown, an auxiliary support plate 25 is rotatably mounted on the armrest 23 away from the desktop fixing part 4. The auxiliary support plate 25 can rotate in the vertical direction. By fixing a horizontal limiting plate 26 below the pivot of the auxiliary support plate 25 and on one side of the armrest 23, the auxiliary support plate 25 can only rotate upwards, and the rotation angle is limited to 180°. When the auxiliary support plate 25 is in an extreme position, it abuts against the bottom surface of the control table 3 in the first position. In this way, one end of the control table 3 is supported by the support rod 41, and the other end is supported by the auxiliary support plate 25, avoiding instability caused by a single support for the control table 3.

[0044] Example 4:

[0045] This embodiment, based on the above embodiments, provides a specific lifting structure. The lifting part 5 is disposed between the seat body 2 and the base frame 1, and is used to adjust the overall height of the seat. As a preferred embodiment, the lifting part 5 can adopt the telescopic cylinder used in existing pneumatic lifting chairs.

[0046] Of course, the lifting unit 5 can also adopt a mechanical structure, that is, a spiral lifting mechanism consisting of a rotating nut and a threaded lifting rod is installed inside the base frame 1. The rotating nut is connected to a horizontal rocker arm through a set of bevel gears, converting the rotational motion of the rocker arm into the rotation of the nut. The rotation of the nut drives the threaded lifting rod, which is precisely matched with it, to make a strictly vertical linear motion, thereby raising or lowering the seat body 2. This purely mechanical structure not only realizes stepless adjustment of the seat height, but also has a self-locking function, which can be locked safely and reliably in any position.

[0047] In this embodiment, regardless of which type of lifting unit 5 is used, it is preferable to position the lifting unit 5 directly below the center of the seat cushion, and to arrange multiple auxiliary support legs 51 around the lifting unit 5, such as... Figure 5As shown, auxiliary support legs 51 are located at the four corners of the bottom of the seat body 2. Each auxiliary support leg 51 includes a bottom support rod 511 and a top support rod 512. The bottom end of the bottom support rod 511 is fixedly connected to the base frame 1, and the top end of the top support rod 512 is fixedly connected to the bottom of the seat body 2. The two can be fixedly connected by flange connection, welding, etc. The bottom support rod 511 is a cylindrical structure with a vertical sliding hole. The top support rod 512 is slidably inserted into the sliding hole of the bottom support rod 511. The outer wall of the top support rod 512 is in contact with the hole wall of the bottom support rod 511. As the lifting part 5 rises and falls, the top support rod 511 also slides up and down relative to the bottom support rod 511. When the seat body 2 is subjected to uneven force and has a tendency to tilt, the friction limit between the outer wall of the top support rod 512 and the hole wall of the bottom support rod 511 stabilizes the seat body 2 and ensures the stability of the seat body 2.

[0048] It should be noted that when the lifting unit 5 uses a telescopic cylinder, the lifting cylinder must comply with SGS certification. If the usage level is Class 4 or above and the maximum static load is greater than 150kg, and there is sufficient strength to stabilize the seat body 2, then auxiliary support legs are not required. In this case, the upper end of the telescopic cylinder can be rotatably connected to the seat body 2, allowing the control personnel to sit on the seat and let the seat body rotate with the rotation of their upper body.

[0049] Example 5:

[0050] This embodiment addresses the problems of difficulty getting in and out of the seat after raising its height and the lack of leg support during prolonged sitting. Figure 2 and Figure 3 As shown, a footrest 6 is also provided on the base frame 1. The footrest 6 includes one or more step plates 61 horizontally arranged in the base frame 1. In this embodiment, a step plate 61 is arranged vertically, forming a two-level step structure together with the anti-slip foot pedal 62, so that the total height of the footrest 6 is 35-40cm, and the height difference between each step of the footrest 6 is 17-20cm. The surface of the step plate 61 is provided with anti-slip texture, and the top layer of the footrest 6 is the anti-slip foot pedal 62. The anti-slip foot pedal 62 is arranged in the base frame 1 through a sliding mechanism. The sliding mechanism includes a slide rail 63 arranged in the base frame 1. The anti-slip foot pedal 62 is slidably arranged in the slide rail 63 on both sides, so that it can be translated along the front and back direction of the seat body 2 and extend out of the base frame 1, so that controllers of different body types can find the most comfortable leg support position. Of course, it should be noted that locking mechanisms such as bolt locking and locking pins (not shown in the figure) can be set on the slide rail 63 to ensure that the anti-slip foot pedal 62 can be locked after being adjusted to a suitable position, so as to prevent the anti-slip foot pedal 62 from moving accidentally during operation; at the same time, in order to avoid interference between the upper control table 3 and the foot pedal 6, the foot pedal 6 should be set on the other side of the base frame 1 relative to the tabletop fixing part 4.

[0051] Example 6:

[0052] To ensure the overall stability and environmental friendliness of the equipment, this embodiment includes multiple support legs 11 on the bottom surface of the base frame 1. Each support leg 11 has a support pad 12 made of elastic material such as rubber at its base. This prevents the seat from moving accidentally in the control tower environment and avoids scratching the delicate and expensive anti-static flooring of the control tower. Figures 1 to 3 As shown, the base frame 1 is a rectangular frame, with legs 11 set at the four corners of the rectangular frame, and supports can also be set on the bottom surface of the step plate 61 for support.

[0053] Based on the above embodiments, the operating principle of this utility model is as follows: Before the controller sits down, the control table 3 can be easily rotated to the second side position, ensuring that the auxiliary support plate 25 overlaps with the corresponding armrest 23, allowing for unobstructed seating. After sitting down, the auxiliary support plate 25 is rotated 180 degrees and then the control table 3 is rotated back to the first front position and fixed by the magnetic connector 24, allowing the auxiliary support plate 25 to abut against the bottom surface of the control table 3. Subsequently, if a new controller uses this chair, the seat is adjusted to the height that provides the best tower view by operating the lifting unit 5, and the angle of the monitor bracket 44 is adjusted according to personal preference. During work, the keyboard, mouse, progress sheet, water cup, etc., can all be placed on the integrated control table 3, within easy reach. The legs can be naturally placed on the non-slip footrest 62, which is adjustable in height and fore-aft position, providing effective support. The entire system works together to significantly improve the efficiency, comfort, and safety of control work.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
