Abstract

We provide affordable elevators that meet specific needs, reducing physical strain and enabling safe and secure movement to and from the second floor. [Solution] The structure comprises a box frame 2, which is a structure similar in shape to stairs, for eliminating the difference in height of stairs; two shafts 5 provided inside the box frame 2; treads 4 attached to the two shafts 5 and configured to be movable up and down; and a winch wire 6-1 stretched inside the box frame 2 to enable the treads 4 to move up and down. The treads 4 slide up and down on the shafts 5 by the movement of the winch wire 6-1. The box frame 2, shafts 5, treads 4 and winch wire 6-1 are integrally constructed, and each component for moving up and down is unitized.
