Abstract
A track driven power door operator selectively and automatically opens a door swingably mounted on a door frame. The power door operator includes an elongate track housing mounted on the door frame and a power screw disposed within the track housing. A drive is provided for powering the rotation of the power screw about the horizontal axis for moving a slider block linearly along the horizontal axis upon its activation. An arm link is pivotally connected at one of its ends to the slider block and pivotally connected at its other end to the door. A control is provided for controlling the operation of the motor for moving the slider block which rotates the door between its closed and open positions.
