Abstract A self-righting mailbox support has a tubular vertical member having its lower end adapted to be sunk in the ground, a crossmember secured to the buried end resisting rotation. A plug in the vertical member is rotatably contained in its upper end and has a retaining cap plate secured at its top for rotating on the top of the vertical member. An elongated mailbox-supporting-arm has one end welded to the plug cap. A coil spring contained in the vertical member has one end secured to the capped plug and its other end secured to an anchor plug which is secured within the vertical member by a bolt therethrough, the spring acting as a torsion spring for returning the mailbox end of the supporting arm to its normal position when the latter end has been struck by a passing vehicle.
A mailbox support comprising a tubular upright member adapted to have one end secured in the ground alongside a roadway, a capped plug rotatably contained on the open upper end of the upright member, an elongated horizontally-disposed member secured at one end to the capped plug and having its other end normally positioned close to the Roadway and adapted to be supportingly secured to a mailbox, a helical coil spring contained in the upright member, an anchor plug contained in the upright member, the plug being secured to the upright member by bolt means therethrough, each end of the spring being at least partially bent to extend radially of the spring, the capped plug having a slot across its lower end, the anchor plug having a slot across its upper end, the spring bent upper end lying in the capped plug slot, the spring bent lower and lying in the anchor plug slot, a pin extending diametrically across the capped plug slot below the spring bent upper end, and a pin extending diametrically across the anchor plug slot above the spring bent lower end, whereby when the mailbox end of the horizontally disposed member is struck by a vehicle it swings away from the roadway and is returned to its normal position by the spring.
