These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0023] Reference Figure 1 and Figure 2 As shown, this application discloses a handrail lifting mechanism, which includes a fixed component 10, a movable component 20, a slide rail mechanism 30, a gas spring 40, and a control component 50. The user activates the gas spring 40 through the control component 50, which serves as a power source to drive the movable component 20 to rise and fall relative to the fixed component 10 along the guide of the slide rail mechanism 30, thereby realizing the synchronous lifting and lowering of the handrail installed on the movable component 20.

[0024] Thus, by cooperating with the gas spring 40 and the slide rail mechanism 30, only the control component 50 is needed to achieve smooth and easy lifting and lowering of the armrest, making operation convenient and effortless. At the same time, this mechanism has a simple structure and can be applied to different types of seating, adapting to users of different heights and body types, and improving comfort.

[0025] The fixing assembly 10 includes two sets of fixing plates 11 and a connecting plate 12, with the two sets of fixing plates 11 arranged vertically at intervals. The connecting plate 12 is connected to the fixing plates 11 by welding, riveting, or bolting, and is perpendicular to the fixing plates 11. To further enhance stability, a triangular reinforcing rib (not shown in the figure) can be added between the two sets of fixing plates 11.

[0026] Compared to a single fixing plate 11, the upper and lower fixing plate 11 frame structure in this application, combined with the connecting plate 12, forms a highly rigid and stable whole, which can more effectively resist the overturning moment generated during use.

[0027] Furthermore, the cylinder 41 of the gas spring 40 is connected to the connecting plate 12. In this embodiment, the connecting plate 12 is vertically arranged, and the gas spring 40 achieves lifting and lowering in the vertical direction. Therefore, this design makes full use of the vertical surface of the connecting plate 12, providing a sufficient and reliable mounting base for the cylinder 41 and ensuring the stable transmission of thrust.

[0028] At the same time, the force of the gas spring 40 can be distributed more directly and evenly to the two sets of horizontally set fixed plates 11 through the connecting plate 12, and finally transmitted to the seat, which greatly optimizes the force path and enhances the rigidity and stability of the entire armrest lifting mechanism.

[0029] The movable component 20 includes a movable plate 21 and a lifting plate 22 fixed to the movable plate 21. There are two sets of movable plates 21, which are arranged vertically at intervals.

[0030] The fixed plate 11 has a relief portion 111 that bends away from the movable plate 21. The relief portion 111 and the movable plate 21 together form a space for accommodating the gas spring 40. In this way, by setting the bend relief portions 111 at both ends of the fixed plate 11, it and the movable plate 21 together form a regular "storage compartment". This not only makes efficient use of vertical space and makes the handrail lifting mechanism compact, but more importantly, it perfectly solves the problem of arranging the gas spring 40, realizing interference-free, integrated, and concealed installation, while enhancing the local rigidity of the overall component.

[0031] The lifting plate 22 includes a connecting part 222 and a supporting part 223, which are L-shaped. Specifically, the connecting part 222 is fixed parallel to the movable plate 21 and rises and falls synchronously to transmit power. The horizontally extending supporting part 223 is specifically used for installing and fixing the external handrail. The included angle between the connecting part 222 and the supporting part 223 is not limited here and can be adjusted according to the installation position of the handrail on the supporting part 223.

[0032] The slide rail mechanism 30 includes at least one set of movable slide rails 31 and stationary slide rails 32. The stationary slide rails 32 are connected to the fixed component 10, and the movable slide rails 31 are connected to the movable component 20. In this embodiment, the slide rail mechanism 30 includes two sets of movable slide rails 31 and stationary slide rails 32. The two sets of stationary slide rails 32 are respectively fixed to opposite sides of the fixed component 10, and the two movable slide rails 31 are respectively fixed to opposite sides of the movable component 20.

[0033] The two sets of moving slide rails 31 and stationary slide rails 32 are located on both sides of the gas spring 40. This symmetrical layout effectively balances the lateral forces on the moving component 20 during lifting and lowering, preventing one side from jamming.

[0034] In one embodiment, a ball or roller bearing is provided between the stationary slide rail 32 and the movable slide rail 31 to ensure smooth and low-noise sliding of the movable slide rail 31 relative to the stationary slide rail 32. Furthermore, a limiting block (not shown in the figure) is provided at the end of the stationary slide rail 32 to prevent the movable component 20 from overtraveling and disengaging during lifting, ensuring safe operation. In this embodiment, the limiting block is engaged with the end of the stationary slide rail 32 to facilitate the assembly and disassembly of the movable slide rail 31 relative to the stationary slide rail 32.

[0035] The cylinder 41 of the gas spring 40 is connected to the fixed assembly 10, and the piston rod 42 of the gas spring 40 is connected to the movable assembly 20. During operation, the cylinder 41 remains stationary as an anchor point, and the extension and retraction of the piston rod 42 directly drives the movable assembly 20 and the handrail fixed thereon, achieving smooth linear lifting and lowering.

[0036] The control assembly 50 includes a control button 51 and a control cable 52. The control button 51 controls the start and stop of the gas spring 40 via the control cable 52, so the handrail can be started and stopped at any position simply by pressing the control button 51. Specifically, one end of the control cable 52 is connected to the control button 51, and the other end is connected to the release valve of the gas spring 40.

[0037] The lifting plate 22 has a through hole 221 for the control cable 52 to pass through. Preferably, the through hole 221 should be fitted with a protective ring made of rubber or plastic to prevent the metal edge from cutting the control cable 52.

[0038] Please refer to the reference again. Figure 3 As shown, this application also discloses a seating arrangement, which includes an armrest frame 60, an armrest board 70, and an armrest lifting mechanism. A fixed component 10 is connected within the armrest frame 60, and a movable component 20 is connected to the armrest board 70.

[0039] The top of the handrail frame 60 has a through groove 61 for the handrail lifting mechanism to move up and down. The connecting part 222 moves up and down along the through groove 61, and the support part 223 is located outside the through groove 61.

[0040] In this embodiment, the handrail panel 70 is located above the handrail frame 60, and the projection of the handrail panel 70 on the vertical plane covers the handrail frame 60 to achieve an aesthetically pleasing concealed effect. Preferably, a rubber sealing strip can be provided on the lower surface of the handrail panel 70, so that when the handrail is lowered to its lowest position, the handrail panel 70 can fit tightly against the top of the handrail frame 60, which serves to prevent dust and reduce noise.

This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
