发明名称 Golf ball retriever
摘要 A device for retrieving golf balls consists of a pair of discs or disc portions rotatably mounted upon a plastic body. The shaft used to rotatably support the discs also serves to maintain the prongs of the body in a spaced relationship in which they develop an optimal amount of force upon the discs. The head assembly consists of only a few parts, and no supplemental means is necessary to secure them.
