Abstract: An aft pivot assembly includes a height adjustment mechanism integrated into a device for mounting a payload, to enable release of the payload. The aft pivot assembly releasably secures an aft portion of the payload, such a pod, store, ordinance, or fuel tank. The aft pivot assembly includes a shaft operable with the mount device and a release component, the shaft being rotatable about multiple shaft axes relative to the mount device so as to either minimize or eliminate carriage loads about the aft portion, while reacting jettison loads during a jettison event or phase. The rotation of the shaft about its shaft axes can further be limited via a limit device. As the payload transitions from a carriage phase to a jettison phase, the shaft moves in multiple degrees of freedom and in multiple axes relative to the mount device.

Abstract: A pivotal ice fishing hole cover selectively covers a hole in an ice layer over a body of water, while permitting an ice fishing line to pass through and into the water. A ring rests adjacent to and circumscribes the ice fishing opening. A pair of hinges are affixed between the ring and a pair of pivotal lid portions, allowing the lid portions to pivot between a first closed configuration parallel to the ice that blocks the ice fishing opening and a second open configuration that allows access thereto. An ice fishing line opening between the pair of pivotal lid portions remains unobstructed regardless of wether the pivotal lid portions are closed or open. The closure is spring loaded, and with the push of a button will release from the lid, thereby allowing the spring hinges to pivot the lid from closed to open position.
