摘要: An automatic gate opening device consisting of two arm members pivotally attached to form a link. One end of the link is pivotally attached to one end of a standoff. The second end of the standoff is fixedly attached to a hinge post supporting the gate. The second end of the link is pivotally attached to the gate. An electrically powered linear actuator is pivotally attached to the post arm and gate arm through levers. The solar panel charges a battery which, through a receiver unit, powers the actuator. Gate operator actuates gate with a portable transmitter.
