  • Patent number: 4991896
    Abstract: A golf ball retriever (10) having a plurality of disks (24) spaced apart by spacer tubes (26) and secured to a rod (22) which is rolled over the bottom of a water hazard to pick up golf balls (28). The rod (22) is supported by a frame (16) which is secured to an elongated handle (12) by a pivot joint (14) which is selectively lockable in one of two positions. In its deployed position, the pivot joint (14) is locked so that the rod (22) is held perpendicular to the length of the elongated handle (12). In the storage position, the pivot joint (14) is locked to that the rod (22) is substantially parallel to the elongated handle (12) so that the golf ball retriever (10) may be easily stored in a golf bag. The golf ball retriever (10) picks up golf balls (28) in a broad strip without requiring visual guidance of the retriever (10) because golf balls (28 ) tend to become aligned between two disks (24) as the retriever is rolled over a golf ball.
