摘要:
A rolling collection tool allows for retrieval of ground objects including pine cones by a user while standing erect. A method for construction of the device is provided in which a plurality of wires are formed into a generally oval shaped chamber and covered in a flexible covering in sets of two or more wires. The chamber is connected to a bail and handle and rolls to pick up and store objects in the chamber until emptied. The objects enter the chamber as the device rolls by temporary separation of the covered wires for the object, and the device retains the objects by resilient return movement of the covered wires to their original position. The flexible covering on the wires rotates around sets of the wires as the device retrieves objects.
