发明名称 Collapsible grapple
摘要 A collapsible grapple comprises a pair of selectively assembleable members. The first member includes a pair of elongated shanks or side elements confluent at their upper ends to form a single part and defining between them an elongate slot. The second member similarly comprises a pair of elongated shank or side elements confluent at their upper ends to form a single part and defining between them an elongate slot. The side elements of the second member converge below their upper ends to form a first loop, then part and converge again below the first loop to form a second loop between the first and second convergences. The lower ends of the side elements of both members extend away from the elongated slot and have pointed ends to define a pair of hooks lying in substantially the same plane as the side elements.
