Double deck elevator with adjustable floor height

摘要

A double deck elevator includes a floor height adjusting mechanism that adjusts the distance between the upper and lower decks located within a cage frame. The adjusting mechanism includes a pantograph having an upper portion coupled to the upper deck and lower portion coupled to the lower deck. A central portion of the pantograph is fixed to a portion of the cage frame. A screw is coupled to the upper or lower portion to cause the pantograph to expand and contract to adjust the distance between the upper and lower decks. The screw is driven by a motor located between the upper and lower decks.
