Gate operator unit

A device for automatically opening and closing a gate comprising:

• an actuator link including a first arm and a second arm, said arms each having a first and a second end, said first ends being pivotally attached;
• a standoff having a first end and a second end, said standoff rigidly attached at said first end to a hinge post of said gate, said second end being removed from said hinge post;
• a first arm lever with a first end rigidly attached to said first arm and a second end removed therefrom;
• a second arm lever with a first end rigidly attached to said second arm and a second end removed thereform;
• and
• a linear actuator having a first end and a second end and capable of increasing and decreasing in length;
• power means for operating said linear actuator, said power means connected to said linear actuator;
• means for activating said power means;
• wherein said first end of said linear actuator is connected to said second end of said first arm lever, and said second end of said linear actuator is attached to said second end of said second arm lever, said linear actuator thereby capable of pivoting said actuator link, and, having said second end of said first arm attached to said standoff and said second end of said second arm attached to said gate, the pivoting thereby moving said gate between an open position and a closed position.

A device for automatically opening and closing a gate, comprising:

• an actuator link including a post arm and a gate arm each with a first and a second end, with said first ends of said post arm and said gate arm pivotally attached;
• a linear actuator having a first and a second end, said linear actuator capable of expanding and contracting in length;
• a gate arm lever with a first and a second end, rigidly attached at said first end to said gate arm, said gate arm lever extending substantially perpendicular to said gate arm, and with said second end of said gate arm lever pivotally attached to said first end of said linear actuator;
• a post arm lever with a first and second end, rigidly attached at said first end to said post arm, said post arm lever extending substantially perpendicular to said post arm, and with said second end of said post arm lever pivotally attached to said second end of said linear actuator;
• a hinge post including at least two hinges for supporting said gate and said gate opening device;
• a stop post for arresting motion of said gate and maintaining said gate in a closed position;
• a standoff comprising a longitudinal member having a first and a second end and rigidly attached at said first end to said hinge post at a point between said hinges, said standoff extending outward at an angle of approximately 1471/2 degrees from a plane formed by said gate when in a closed position;
• a power supply comprising at least one DC battery and a solar cell to recharge said battery, said power supply for actuating said linear actuator;
• a receiver means for receiving a radio signal from a remote transmitter and non-manually actuating said linear actuator;
• a switch for manually activating said linear actuator;
• key means for overriding said manual switch and thereby preventing the manual actuation of said linear actuator without said key means;
• means to detach said gate arm from said gate thereby moving said gate without operation of said linear actuator;
• wherein the combination of said standoff, said actuator link, said post arm lever, said gate arm lever, and said linear actuator moves said gate between a closed position when said gate is substantially across a roadway and against said stop post to an open position approximately 90.degree. therefrom.
