Background

An elevator is a vertical elevator powered by an electric motor and equipped with a box-like car for carrying people or cargo in a multi-story building. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor.

The national standard residential design code implemented from 6.1.1999 stipulates that elevators must be installed in houses with seven or more floors or the top floor of the house being more than 16m from the outdoor design ground, and the houses or other public buildings after the standard promulgation must be provided with elevators according to the standard strictly, but most of the floors of the houses before 1999 meet the standard for installing the elevators, but because the building is in consideration of cost and is not provided with the elevators, the elevator is inconvenient for residents living in old houses without the elevators, especially for old residents living in 2 floors, going upstairs and downstairs are a big problem, and for this reason, some cities begin to go out from old houses in the next year and add the transformation scheme of the elevators, but is limited by the existing residential building structure, and generally need to install a vertical elevator outside the building, installation and maintenance costs are high and lighting of low-rise residents is also affected.

In order to solve the problem that the existing residential building is high in cost when a vertical lifting elevator is additionally installed, various corridor seats capable of being installed in a corridor appear in the market, and the corridor seat is an elevator running on the side face of a staircase. The main function is to help the people who are inconvenient to move (disabled people and old people) to go up and down stairs in home. The structure of the seat elevator generally comprises a track, a driving device and a seat, and has two structures of a continuous type and a sectional type, and although the elevator can convey people or objects up and down on the premise of not damaging the structure of the existing house, the sectional type structure is inconvenient to use, the continuous type structure occupies a larger space, the safety is poor, and the problem that the old people above the 5 th floor are difficult to go out is not fundamentally solved.
