Latest Patents

Randall holds a patent for an "Elevator car with improved car door clutch." This invention features a clutch that is pivotally carried by a car door and is biased to an operative position. The design allows drive rollers of an adjacent hatch door to be engaged by 'open' and 'close' vanes. A first parallelogram linkage operates the close vane in direct response to the car door position, working in a direction opposite to the initial car door opening movement. Additionally, a second parallelogram linkage is associated with the open vane, which operates when the open vane contacts a hatch door roller at the start of door opening. This mechanism unlocks the car door by retracting a plunger from an opening in the car door sill. The car door clutch bias can be manually overcome by authorized maintenance personnel, allowing for disengagement from a hatch door.
