  • Patent number: 5362271
    Abstract: Playthings, such as dolls (10, 12), figures or toy animals (22) are provided. The playthings are provided singly or in pairs. The playthings have limbs, such as arms, or other appendages such as tails or trunks, extending from their bodies, the limbs or appendages being provided with connection elements, such as magnets (14), for removably attaching limbs together to simulate "hand holding" or to attach to metal surfaces or to "pick up" metal objects. In alternative embodiments the magnets are arranged so that they will repel each other so that certain limbs or appendages will not attach to each other. In another embodiment the playthings can be manipulated by the thumb and fingers, such as in the form of recesses (44) provided in the clothes or by strings (38), such as in the form of a marionette (46).
