AI Technical Summary
Existing RV concealed folding ladders have narrow step crossbars, are difficult and unsafe to use, and lack handrail facilities, resulting in difficulties and high risks in their use.
A folding ladder mechanism was designed, comprising an outer side plate, an inner side plate, a step, a rotating groove, a rotating shaft, a cylinder, and a handrail assembly. The step is driven to unfold and fold by the cylinder, and combined with the foldable handrail, it improves safety and ease of use.
It enables the convenient unfolding and folding of stairs without taking up space, improving safety and labor-saving, and adapting to the installation needs of different spaces.
