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.

What is claimed is: 1. An object retrieval device comprising: a frame that is a single, slender member; a retrieval means that includes a single pivot arm having a proximal end and a distal end, and a mounting assembly for rotatably mounting said proximal end of said pivot arm in said frame; a susp
What is claimed is: 1. An object retrieval device comprising: a frame that is a single, slender member; a retrieval means that includes a single pivot arm having a proximal end and a distal end, and a mounting assembly for rotatably mounting said proximal end of said pivot arm in said frame; a suspension means for suspending said frame and retrieval means above an object to retrieve; an actuation means assembled in said frame, said actuation means including a gravity-actuated trigger for holding said pivot arm in a cocked position, wherein said trigger is held in a cocked trigger position as long as a tension force is applied to said suspension means and automatically triggers under force of gravity when said tension force is removed, thereby releasing said pivot arm from said cocked position and allowing said pivot arm to swing toward said frame; wherein said pivot arm and said frame are adapted to catch and hold said object to retrieve between said pivot arm and said frame. 2. The object retrieval device of claim 1, wherein said trigger is slidably mounted on said frame, wherein a catch means is provided on said proximal end of said pivot arm for holding said pivot arm in a cocked position on said trigger. 3. The object retrieval device of claim 2, wherein said trigger has a trigger body with a trigger edge and wherein said catch means includes a roller bearing that is restrainable by said trigger edge when said actuation means is in said cocked position. 4. The object retrieval device of claim 3, wherein said trigger body has a trigger foot that is angled relative to said trigger body toward an anterior side of said frame, wherein said catch means further includes a catch groove, and wherein a lower edge of said trigger foot is catchable in said catch groove so as to restrain said pivot arm in a closed position. 5. The object retrieval device of claim 2, wherein said frame has an anterior side with an anterior channel, wherein parallel and opposite vertical grooves are provided in said anterior channel, and wherein said trigger is slidably mounted in said grooves. 6. The object retrieval device of claim 5, wherein said frame has a posterior side with a posterior channel, wherein parallel and opposite vertical grooves are provided in said posterior channel, wherein said actuation means further includes a trigger guide with a cantilevered guide plate and a guide slot formed in said guide plate in which an upper end of said trigger is receivable, wherein said trigger guide is assemblable in said posterior grooves, such that said cantilevered guide plate extends toward said anterior side of said frame. 7. The object retrieval device of claim 2, wherein said trigger has an upper end with a means for receiving an end of said suspension means. 8. The object retrieval device of claim 2, wherein said frame has a frame opening in a center section of said frame, with a side frame on each side of said opening, and said mounting assembly is mounted in said frame opening, wherein said trigger has a trigger opening and said trigger is slidably mounted on said frame such that said trigger opening overlays said frame opening and said proximal end of said pivot arm extends through said trigger opening on an anterior side. 9. The object retrieval device of claim 8, wherein said mounting assembly includes a shaft that extends across said frame opening and through said side frame, wherein said proximal end of said pivot arm is rotatably mounted on said shaft such that said distal end of said pivot arm is positioned on said anterior side of said frame. 10. The object retrieval device of claim 9 further comprising a biasing means for biasing said distal end of said pivot arm toward said closed position. 11. The object retrieval device of claim 10, wherein said biasing means is a torsion spring that is assembled around said shaft, with one end of said spring exerting a force against said frame and another end exerting a force against said pivot arm. 12. The object retrieval device of claim 1 further comprising an adjustable toot that incorporated into a lower end of said frame. 13. The object retrieval device of claim 12, wherein said foot has a guide bar for maintaining proper alignment of said foot and lateral spring means for retaining said foot at a proper adjustment within said frame. 14. The object retrieval device of claim 1, wherein said pivot arm includes a gripping element for gripping said object to retrieve. 15. The object retrieval device of claim 14, wherein said gripping element includes two gripping protrusions with a recess therebetween. 16. The object retrieval device of claim 14, wherein a gripping element-receiving recess is provided in said frame for receiving a tip of said gripping element when said retrieval means is in said closed position. 17. The object retrieval device of claim 1, wherein said pivot arm has a curved contour for scooping said object to retrieve.
