Abstract
The invention is an elevator. The elevator is driven by a rack and a chain. The elevator also comprises a transportable frame, a floor, and an elevator shaft. The purpose of the invention is, by using a rack and chain lifting device to drive the elevator, to allow the elevator to be driven from the bottom. Driving the elevator from the bottom makes the structural integrity of the elevator box unnecessary, so that the elevator box can be replaced with an elevator box façade and a fabric door, making the elevator lighter and more economical. In addition, the design of the elevator allows for adjacent doors, battery power, and voice control.
