ABSTRACT:
An apparatus for selectively holding an object, such as a mailbox, in an up or down position having an arm pivoted to an upright post. A mailbox support platform is pivotally connected to the outer end of the arm. A linear actuator pivotally connected to the inner end of the arm and anchored on the post operates to pivot the arm from a generally horizontal position to a raised position. A control rod is pivotally connected at its outer end to the mailbox support structure. The inner end of the control rod carries rollers which ride in a vertical track secured to the post. A rigid link interconnects the inner ends of the arm and control rod causing the inner end of the control rod to move along the track and the mailbox support platform to pivot on the arm to maintain the mailbox in a generally horizontal position as it moves between its down and up positions.
