AI Technical Summary
In existing technologies, the wrapping and sealing treatment of stair handrails at bends suffers from rough splicing processes, resulting in enlarged gaps, warping, and sharp edges. The lack of standardized renovation methods affects the aesthetics and safety of building renovations.
The system employs a wrapping assembly that includes the staircase body and handrail. Through the combination of horizontal and vertical panels and connecting components, along with the bending deformation of the elastic plate, it achieves complete wrapping and sealing of the handrail at bends, avoiding warping and sharp edges.
It achieves standardized wrapping at the corners of stair handrails, improves operational standardization and the neatness of the renovated appearance, enhances safety and aesthetics, and is suitable for the renovation of public buildings and villas.
