US Patent 7318612 Gravity actuated retrieval device

Gravity-actuated device for retrieving various types of objects from various ground surfaces. The device has a single retrieval arm pivotably mounted on a slender frame. Gripping elements on the end of the retrieval arm allow the operator to grip a variety of objects, including soft flexible objects, such as a glove, rigid slender objects, such as an arrow, or objects having a loop or strap, such as a thermos bottle. The device is suspended from above to retrieve the object and collapses to a slender compact configuration when not in use.
