Patent ID: 8413297

Claim:
An apparatus for use with a post and a corresponding pivoting barrier, the apparatus comprising: an L-shaped frame comprising a first leg defining a first leg axis and a second leg defining a second leg axis, the L-shaped frame configured to be affixed to the post; a barrier pivot extending from the first leg of the L-shaped frame, the barrier pivot comprising at least one barrier pivot point; and a linear actuator arm mounting bracket extending from the second leg of the L-shaped frame, the linear actuator arm mounting bracket configured to connect to a proximal end of a linear actuator arm and support the linear actuator arm at the proximal end of the arm so that the arm can pivot around an actuator arm axis extending through the linear actuator arm mounting bracket, the axis of pivot of the linear actuator arm being substantially parallel to an axis of pivot through the barrier pivot point; the barrier pivot on the first leg and the linear actuator arm mounting bracket are configured and arranged to provide a distance A between the linear actuator arm axis of pivot and the axis of pivot through the barrier pivot point measured along the first leg axis and a distance B between the linear actuator arm axis and the axis of pivot through the barrier pivot point measured along the second leg axis which are substantially equal.
