Abstract: A wire maze toy includes an endless wire frame that is of substantially uniform cross-sectional configuration over its entire length and is configured to form multiple curves. A carriage including two slider members is fitted on the wire frame and is slidable along the wire frame. A spring structure has two ends connected to the two slider members respectively. The spring structure and the wire frame are dimensionally related such that tension in the spring structure depends on relative positions of the slider members along the wire frame.

Abstract: A toy comprising a frame formed from a continuous length of rigid elongated wire having ends. The wire between its ends is bent to form multiple curves to give the frame a three dimensional configuration with top, bottom and sides. The curves of the wire at the bottom lie in a plane to form a flat supporting surface for the frame. A plurality of beads, with a hole in each bead are movably supported on the wire, with the wire passing through each hole. The holes are sufficiently large to permit the beads to freely slide over the curves of the wire between its ends. In alternative embodiments, stop means may be provided at the ends of the wire to hold the beads on the wire or the ends of the wire may be joined by appropriate means, in each case to provide a continuous, endless run for the beads over the entire frame.
