Patent attributes
A vertical linear actuator mechanism for positioning a load at a desired elevation above a support surface is described. The vertical linear actuator mechanism in one aspect thereof comprises an electric motor having a drivable shaft. The drivable shaft is coupled to a linear extendable mechanism having a load connector at a top end thereof. A potentiometer detects the position of the load connector relative to the support surface and provides position signals to a motor controller circuit which monitors the position of the load connector and controls the operation of the electric motor. In another aspect thereof the vertical linear actuator is comprised by a pair of gas spring cylinders interconnected together. The vertical linear actuator mechanism is secured inside a telescopic pedestal and extends and retracts the pedestal.
