1. A rolling toy comprising:

  • a primary roller and a secondary roller;

    said primary roller has a tubular member extending along a longitudinal axis thereof between a left end and a right end;

    said primary roller further has at least a left annular flange and a right annular flange which are fixedly attached to said tubular member;

    said left annular flange and said right annular flange are configured such that said primary roller is rollable on the left annular flange and the right annular flange on a horizontal support surface;

    said tubular member has a substantially cylindrical interior surface facing an interior of the tubular member;

    wherein said left annular flange and said right annular flange are spaced apart along said longitudinal axis and have an equal outer diameter;

    configurations of said primary roller and said secondary roller and weights of the rollers are such that the center of gravity of said rolling toy is located between the left and right annular flanges when said primary roller is positioned having said longitudinal axis oriented horizontally and said secondary roller is disposed on said substantially cylindrical interior surface in a middle section of said tubular member;

    said secondary roller is sized to fit within said tubular member and is adapted for a rolling motion on said substantially cylindrical interior surface;

    wherein at least one of the following includes a helical guiding means;

    (i) said tubular member and (ii) said secondary roller;

    said helical guiding means is/are configured for urging said secondary roller to move longitudinally toward said left end or said right end when said secondary roller is in the rolling motion on said substantially cylindrical interior surface;

    configuration of the primary roller and weights of the primary and secondary rollers are such that, as the primary roller is positioned having said longitudinal axis oriented horizontally, at least one of the following is satisfied;

    (a) a center of gravity of said primary roller is located approximately at a location of a vertical plane, substantially perpendicular to the longitudinal axis, and associated with the left annular flange or to the left of the left annular flange, and(b) the center of gravity of said primary roller is located approximately at a location of a vertical plane, substantially perpendicular to the longitudinal axis, and associated with the right annular flange or to the right of the right annular flange;

    thereby, when said secondary roller is disposed on said substantially cylindrical interior surface in a predetermined location and said primary roller is set in a rolling motion on said horizontal support surface in a predetermined direction, the rolling motion of the primary roller results in a tilting thereof in respect to said horizontal support surface due to one of the following;

    (i) the longitudinal movement of said secondary roller toward said left end, (ii) the longitudinal movement of said secondary roller toward said right end, (iii) the longitudinal movement of said secondary roller toward said left end and subsequent detachment thereof from said tubular member, and (iv) the longitudinal movement of said secondary roller toward said right end and subsequent detachment thereof from said tubular member.
