Technical Field
[0001] This utility model relates to the field of handrail device technology, specifically to a comfortable ergonomic handrail device. Background Technology
[0002] Handrails are widely used in various buildings and facilities, serving as essential equipment to ensure the safety of people's movement. They are commonly found on stairs, escalators, pedestrian railings, and seats. They are generally composed of sturdy handrails and stable supporting components, and are made of various materials, such as stainless steel, wood, and plastic, to suit different scene styles and usage needs. People can maintain their balance by holding onto the handrail while walking or sitting and resting, which is especially convenient for the elderly, children, and people with mobility impairments. In crowded places, they can also guide people to pass through in an orderly manner, effectively preventing safety accidents such as falls and crowding, and safeguarding daily travel.
[0003] In the prior art, such as the armrest device of seat 200720144373.1, the technical solution is as follows: the armrest device of the seat includes a polyurethane armrest and an armrest frame inlaid in the polyurethane armrest. The feature is that it also includes a polyurethane cup sleeve fixed to the armrest frame by screws and a cup sleeve frame inlaid in the polyurethane cup sleeve. The screws are countersunk in the polyurethane armrest. However, the existing armrests are fixedly installed and the angle is not adjustable. They cannot fit the height, gait and grip habits of different users. Tall people may have to bend over to accommodate them, while short people have to lift their arms with difficulty. Long-term use can easily cause physical fatigue and discomfort. When the armrests of multiple seats are used, a large number of people of different body shapes frequently use the armrests. The fixed angle design obviously cannot meet the requirements of ergonomic comfort.
[0004] In view of this, this case arose in response to the aforementioned issues. Summary of the Invention

[0033] A fixing plate 7 is fixedly installed on the front and rear left sides of the device base 1. A first mounting seat 8 is fixedly installed on top of the fixing plate 7. A mounting block 9 is fixedly installed on the left side of the electric cylinder 10 and is hinged to the inside of the first mounting seat 8. A mounting sleeve 11 is fixedly installed on the output end of the electric cylinder 10. A second mounting seat 12 is hinged to the right end of the mounting sleeve 11. A connecting plate 13 is provided on the upper part of the moving frame 14. The second mounting seat 12 is fixedly installed on the bottom of the connecting plate 13. The fixing plate 7 on the front and rear left sides of the device base 1 and the first mounting seat 8 fixedly installed on top of it provide stable support for the first mounting seat 8, ensuring that the position of the first mounting seat 8 is stable, thereby ensuring that the electric cylinder 10 installed on the first mounting seat 8 is firmly installed, which is conducive to the stable operation of the electric cylinder 10 in the future. The electric cylinder 10 provides a reliable foundation for the operation and angle adjustment of the armrest 3. The mounting block 9 on the left side of the electric cylinder 10 is hinged to the inside of the first mounting seat 8. This hinged method allows the electric cylinder 10 to flexibly change its angle during operation, better adapting to the movement changes of the moving frame 14. This ensures smoother power transmission when the electric cylinder 10 pushes the moving frame 14, thereby achieving a more stable angle adjustment of the armrest 3.

This allows the moving frame 14 to stably drive the armrest 3 to rotate, improving the accuracy and stability of the armrest 3 angle adjustment and allowing users to more precisely adjust to a comfortable armrest angle.
[0034] The slide 15 is arc-shaped and is located on the front and rear sides and left and right sides of the movable frame 14. The limiting post 16 is fixedly installed on the front and rear sides inside the device base 1. The arc-shaped slide 15 on the movable frame 14 and the limiting post 16 inside the device base 1 cooperate with each other. The arc-shaped slide 15 limits the rotation path of the movable frame 14, making the movable frame 14 more stable and smooth when rotating, preventing the movable frame 14 from deviating or shaking during rotation, ensuring the stability of the armrest 3 angle adjustment process, and making the user more at ease.
[0035] The inner shape of the armrest groove 6 conforms to the shape of the human arm muscles, and the inner filling of the armrest groove 6 is filled with a resilient material. The design that conforms to the shape of the human arm makes the arm rest more naturally and comfortably. The resilient material can effectively cushion the arm pressure, reduce arm soreness caused by prolonged use, improve the comfort of the user when using the armrest device, and bring a better experience to the user.
[0036] Working principle:
[0037] When in use, the user presses the switch 4 on the armrest 3, which controls the electric cylinder 10 to start. The left end of the electric cylinder 10 is hinged to the first mounting base 8 via the mounting block 9, and the mounting sleeve 11 at the output end is hinged to the second mounting base 12 at the bottom of the connecting plate 13 inside the movable frame 14. When the electric cylinder 10 extends or retracts, it drives the movable frame 14 to rotate around the rotation connection point with the device base 1. The arc-shaped sliding groove 15 on the surface of the movable frame 14 slides along the limiting post 16, limiting the rotation trajectory of the movable frame 14. The rotation of the movable frame 14 drives the armrest 3 to change its angle to adapt to the needs of different users. The user places their arm in the armrest groove 6, which conforms to the shape of the human arm muscles and has elasticity to provide comfortable support.
[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
