DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0026] Please refer to Figure 1-Figure 3The present invention provides an aviation seat bar that can rotate and translate forward, including a tray 1, a sliding mechanism 2 and a tea tray 3.

[0027] The tray 1 is fixed to the middle armrest of the airline seat, and is provided with at least two arcuate grooves 11. In this embodiment, there are three arcuate grooves 11, which can further improve the stability of the tea tray 3 during rotation.

[0028] The sliding mechanism 2 includes at least two sliders 21, each of which is slidably arranged in the corresponding arc-shaped groove 11, and the tea tray 3 is connected to each of the sliders 21. When the slider 21 is in the first position, the length direction of the tea tray 3 is parallel to the length direction of the middle armrest. When the slider 21 is in the second position, the length direction of the tea tray 3 is perpendicular to the length direction of the middle armrest.

[0029] When there is no need to place tea cups on the tea tray 3, the slider 21 is in the first position (eg Figure 1 ), at this time, the length direction of the tea tray 3 is arranged longitudinally, so as to adapt to the needs of a narrow bar; when two tea cups need to be placed side by side on the tea tray 3, since the width of the tea tray 3 is not enough to accommodate the two tea cups placed side by side, the tea tray 3 can be pushed, and the tea tray 3 drives the slider 21 in the arc groove 11. When the slider 21 reaches the second position (such as Figure 2 ), at this time, the length direction of the tea tray 3 is perpendicular to the length direction of the middle armrest, and the length of the tea tray 3 can accommodate two tea cups placed side by side. Therefore, the passengers on both sides of the bar will not feel unequal, thereby improving the user experience.

[0030] To accommodate smaller beverage cups, please refer to Figure 1 and Figure 2 In a preferred embodiment, two cup grooves 12 are provided on the tray 1. When the slider 21 is in the first position, the two cup grooves 12 are both located below the tea tray 3. When the slider 21 is in the second position, the two cup grooves 12 are both located on the side of the tea tray 3. Therefore, when the tea tray 3 is rotated to the horizontal position, the two cup grooves 12 can be exposed for passengers to place other smaller beverage cups, thereby expanding the usable area of ​​the bar.

[0031] In order to reduce the friction between the tea tray 3 and the tray 1 during rotation, please refer to Figure 3 In a preferred embodiment, the rotatable and forwardly translatable aviation seat bar also includes a first friction plate 4, which is fixed on the tea tray 3 and abuts against the tray 1. The first friction plate 4 can be made of plastic material, so that it has good wear resistance.

[0032] In order to realize the connection between the slider 21 and the tea tray 3, please refer to Figure 3-Figure 6 In a preferred embodiment, each of the sliders 21 is provided with a through-hole; the sliding mechanism 2 further includes at least two rotating shafts 22, one end of each of the rotating shafts 22 is fixed to the tea tray 3, and the other end of each of the rotating shafts 22 is inserted into the corresponding through-hole and rotatably connected to the corresponding slider 21, so that the slider 21 can rotate relative to the tea tray 3 to reduce the friction between the slider 21 and the arc-shaped groove 11.

[0033] In order to realize the connection between the rotating shaft 22 and the tea tray 3, please refer to Figure 3-Figure 6 In a preferred embodiment, a fixing screw hole 31 is provided on the tea tray 3, and one end of each rotating shaft 22 is formed with an external thread that matches the fixing screw hole 31. One end of the rotating shaft 22 is threadedly connected to the corresponding fixing screw hole 31, so that when installing, the rotating shaft 22 is passed through the through hole on the slider 21 and then threadedly connected to the fixing screw hole 31, which is convenient for quick installation.

[0034] To prevent the slider 21 from being separated from the shaft 22, please refer to Figure 3-Figure 6 In a preferred embodiment, the sliding mechanism 2 also includes a clamping plate 24, which is fixedly connected to the other end of each of the rotating shafts 22. The clamping plate 24 abuts against the tray 1. When in use, the clamping plate 24 can limit the slider 21 to prevent it from separating from the rotating shaft 22.

[0035] In order to realize the fixed connection between the clamping plate 24 and the other end of each rotating shaft 22, please refer to Figure 3-Figure 6 In a preferred embodiment, a plurality of mounting holes are provided on the clamping plate 24 , and the rotating shaft 22 is inserted into the corresponding mounting holes. A protrusion 221 is formed at the other end of the rotating shaft 22 , and the protrusion 221 abuts against the clamping plate 24 .

[0036] To reduce the friction between the clamping plate 24 and the tray 1, please refer to Figure 1 In a preferred embodiment, the rotatable and forwardly translatable aviation seat bar also includes a second friction plate 5, one end of the second friction plate 5 is connected to the clamping plate 24, and the other end of the second friction plate 5 is in contact with the tray 1. The second friction plate 5 can be made of plastic material, so that it has good wear resistance.

[0037] In order to adjust the tightness of the tea tray 3 during rotation, please refer to Figure 3 and Figure 4In a preferred embodiment, the clamping plate 24 is provided with an adjustment screw hole. The rotatable and forwardly movable airline seat bar further includes a tension adjustment member 6 comprising an adjustment screw 61 and an elastic member 62. The adjustment screw 61 is threaded into the adjustment screw hole, with one end of the adjustment screw 61 abutting against one end of the elastic member 62, while the other end of the elastic member 62 abuts against the second friction plate 5. During use, the screwing depth of the adjustment screw 61 can be changed, thereby changing the compression length of the elastic member 62, thereby adjusting the friction between the second friction plate 5 and the tray 1, and thus adjusting the tension of the tea tray 3 during rotation.

[0038] To facilitate installation of the elastic member 62, please refer to Figure 3 and Figure 4 In a preferred embodiment, the tension adjustment member 6 also includes a first connecting block 63 and a second connecting block 64, one end of the first connecting block 63 is fixedly connected to one end of the elastic member 62, the other end of the first connecting block 63 abuts against one end of the elastic member 62, one end of the second connecting block 64 is fixedly connected to the other end of the elastic member 62, and the other end of the second connecting block 64 abuts against the second friction plate 5.

[0039] In order to better understand the present invention, the following Figures 1-6 The working process of the rotatable and forward-translatable airline seat bar provided by the present invention is described in detail: when there is no need to place tea cups on the tea tray 3, the slider 21 is in the first position (such as Figure 1 ), at this time, the length direction of the tea tray 3 is arranged longitudinally, so as to adapt to the needs of a narrow bar; when two tea cups need to be placed side by side on the tea tray 3, since the width of the tea tray 3 is not enough to accommodate the two tea cups placed side by side, the tea tray 3 can be pushed, and the tea tray 3 drives the slider 21 in the arc groove 11. When the slider 21 reaches the second position (such as Figure 2 ), at this time, the length direction of the tea tray 3 is perpendicular to the length direction of the middle armrest, and the length of the tea tray 3 can accommodate two tea cups placed side by side. At the same time, the two cup grooves 12 are exposed for passengers to place other smaller beverage cups, expanding the usable area of ​​the bar. Therefore, passengers on both sides of the bar will not feel unequal, thereby improving the user experience.
