  • Patent number: 4591152
    Abstract: Amusement apparatus forming a toy or game having a plurality of rod-like elements which are linked up serially end-to-end to form a chain. A user holds one element in his or her hand and uses the one element to link up with a second element. The process is repeated from element to element until the supply of elements is depleted or until the chain is broken. The elements each have a ring at one end and a cranked portion at the other end. The cranked portion fits through the ring of an adjacent element in the chain to form an over-and-under connection between the elements.
