Abstract
An elevator that incorporates a framework that allows multiple autonomous mobile lifts to move independently inside and outside a building or a group of buildings in shafts and corridors in such a way that multiple lifts can share a shaft and/or corridor.
Claims19
An elevator system, comprising:
- a rack lattice installed within at least one elevator shaft;
- a lift having a plurality of driving trains, the lift configured to be movable along the rack lattice in an up, down, diagonal, left, and right direction depending on the geometry of the rack lattice;
- the plurality of driving trains comprising:
- a first gear mounted perpendicularly to a second gear, the first and second gear movable in a vertical, diagonal and horizontal direction along the rack lattice based on the geometry of the rack lattice;
- and
- wherein the rotation of the first gear moves the lift in a first direction along the rack lattice while sliding the perpendicularly mounted second gear through the rack lattice;
- and
- the second gear moves the lift in a second direction along the rack lattice while sliding the perpendicularly mounted first gear through the rack lattice.

An autonomous mobile lift configured for use in an elevator system comprising:
- a rack lattice comprising racks having frustum shaped teeth;
- a driving train, the driving train comprising:
- a first gear mounted perpendicularly to a second gear, the first and second gear movable in a vertical, diagonal and horizontal direction along the rack lattice based on the geometry of the rack lattice;
- and
- wherein the rotation of the first gear moves the lift in a first direction along the rack lattice while sliding the perpendicularly mounted second gear through the rack lattice;
- and
- the second gear moves the lift in a second direction along the rack lattice while sliding the perpendicularly mounted first gear through the rack lattice.

A method of controlling a number of lifts within an elevator system to increase capacity during peak hours of operation and decrease capacity during off-peak hours or remove lifts for maintenance, comprising:
- installing a rack lattice in a vertical direction along at least one elevator shaft and in a horizontal direction along at least one floor slab connected to at least one elevator shaft;
- controlling a lift having a driving train and wheels to enter an elevator shaft, the driving train having a first gear perpendicularly mounted to a second gear;
- engaging a first gear of the driving train with the rack lattice to move the lift into and along a vertical direction within an elevator shaft;
- sliding the second gear along the rack lattice as the first gear rotates;
- engaging the second gear of the driving train to move the lift into and along a horizontal direction along a floor slab connected to the elevator shaft;
- sliding the first gear along the rack lattice as the second gear rotates;
- disengaging the driving train from the rack lattice;
- powering the wheels to move the lift out of the elevator shaft.
