  • Patent number: 5004240
    Abstract: A golf ball retriever includes a self-contained module having a plurality of curved, resilient prongs in the form of cantilevered springs and a housing with a side wall, an open end and a closed end. An end cap having an aperture associated with each prong is disposed across the open end of the housing and retains the prongs. One of the prongs has a shoulder cooperating with a portion of the end cap to form a latching mechanism. A push button arrangement disengages the latching mechanism allowing an axial compression spring to move the prongs from a first position having the prongs substantially disposed within the housing to a second position having the prongs substantially extending from and through the housing's open end. The resilient, elastic prongs bias the push button arrangement toward a latched position. The cantilevered configuration of the prongs places them in a biased relationship with the side wall of the housing and urges the prongs toward the second, extended position.
