Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a handrail structure in an elevator car. Background Art

[0002] Elevators are essential transportation tools in multi-story buildings. Elevator cabins are typically equipped with handrails, which provide support and comfort for passengers while riding. They also provide a secure resting point for passengers in unusual situations, such as sudden stops due to malfunctions. Currently, most handrails are directly fixed to the cabin walls. These protruding handrails take up considerable space in the cabin, and installing them in smaller cabins can make the space even more cramped. Furthermore, handrails are typically fixed at a height suitable for adults, making them too high for children or elderly people in wheelchairs. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a handrail structure in an elevator car, which changes the handrail into a pull-out shape, making it convenient for passengers to choose the state of the handrail according to their needs.

[0005] On the basis of the above solution and as a preferred solution of the above solution: a rotatable limit block is provided on one side of the front side of the mounting frame, and the limit block can be rotated to abut against the outside of the vertical surface or leave the vertical surface.

[0006] On the basis of the above solution and as a preferred solution of the above solution: the upper edge of the vertical surface of the armrest protrudes from the horizontal movable frame to form a hand-holding portion.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: a first mounting opening and a second mounting opening are provided on the car wall, the first mounting opening is 85 to 95 cm high from the ground, and the second mounting opening is 65 to 75 cm high from the ground.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the front side of the mounting frame is installed outside the mounting opening of the car wall, a notch is provided in the middle of the front side of the mounting frame, and part of the vertical surface of the handrail is opposite to the notch.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: mounting openings of different heights are provided on the car wall, and a slidable and retractable handrail assembly is provided in each mounting opening, which is convenient for adults, children or elderly people in wheelchairs to use when taking the elevator; the handrail is a retractable structure, which is usually retracted in the mounting opening, and the surface of the handrail is flush with the car wall, and will not occupy the car space. When the handrail is needed, it can be pulled out for use, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In the description of the present invention, it should be noted that, for directional words, such as the terms "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific protection scope of the present invention.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Therefore, the terms "first" and "second" may explicitly or implicitly refer to one or more of these features. In the description of this utility model, "several" and "a number" mean two or more, unless otherwise specifically defined.

[0017] See the accompanying drawings. The elevator car handrail structure described in this embodiment includes a car wall 1 and two sets of handrail assemblies 2. The car wall 1 is provided with a first mounting opening 11 and a second mounting opening 12 at different heights, each of which is mounted within one of the first and second mounting openings 11, 12. The first mounting opening 11 is 85 to 95 cm above the ground, making it convenient for adults to use it normally. The second mounting opening 12 is 65 to 75 cm above the ground, making it convenient for children or elderly people in wheelchairs to use it when riding the elevator.

[0018] The armrest assembly 2 includes a mounting frame 21 and an armrest 22. A groove 23 for accommodating the armrest is provided in the middle of the mounting frame 21, and slide rails are provided on both sides of the groove 23. The armrest 22 is movable relative to the groove 23. The armrest 22 includes a horizontal movable frame 221 and a vertical surface 222. The horizontal movable frame 221 slides in conjunction with the slide rails. The upper edge of the vertical surface 222 of the armrest protrudes from the horizontal movable frame 221 to form a handheld portion. In the initial state, the armrest 22 can be retracted into the groove 23, and the vertical surface 222 of the armrest is flush with the car wall 1, so as not to occupy space within the car. When in use, the armrest 22 can be pulled out, and the vertical surface of the armrest extends outward from the car wall, making it easier for passengers to hold it.

[0019] The front side of the mounting frame 21 is mounted outside the mounting opening of the car wall 1. A notch 24 is provided in the middle of the front side of the mounting frame 21. A portion of the vertical surface 222 of the handrail 22 is opposite the notch 24, allowing the user to pull out the handrail 22 through the notch 24. A rotatable stopper 3 is provided on one side of the front side of the mounting frame 21. The stopper 3 can be rotated to contact the outside of the vertical surface 222 or to move away from the vertical surface 222.

[0020] The handrail in the elevator car is normally retracted within the mounting opening, with the vertical surface 222 of the handrail 22 flush with the car wall 1. To prevent the handrail 22 from sliding out during elevator movement, the stop block 3 can be rotated so that it abuts against the outside of the vertical surface 222, restricting the movement of the handrail 22. When a passenger needs to use the handrail 22, the stop block 3 is rotated away from the vertical surface 222, and the user pulls the handrail 22 out through the notch 24, providing a convenient support point for the passenger. Adults can use the upper handrail, while children or elderly people in wheelchairs can use the lower handrail.

[0021] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
