ABSTRACT:
An instructional balancing toy set for use, for instance, by preschool children to amuse and entertain the children while at the same time conveying concepts of object size and object weight. The device includes a base and a plurality of vertically stackable balancing members. The base is upwardly converging and frusto-conical in shape and rests on a support surface, and has a circular top lip which receives a generally spherical intermediate second balancing member to hold the spherical member in a predetermined upright proper orientation. The spherical member when properly oriented, includes an upwardly projecting lug at the top thereof which is received in a lug receiver on the bottom of a figurine to support the figurine in upright position on top of the spherical member as a third member of the assembly. The figurine member includes a generally concave depression on the top surface thereof.
Additional vertically stackable balancing members are intended to be stacked in a certain order and have decreasing size and weight characteristics progressively from the bottom of the stack to the top. Each member, in the form of a figurine or portion of a figurine, has a bottom pointed projection for forming a fulcrum when supported in a top depression of another member. Each also has opposing outwardly and downwardly projecting arms terminating in weights of sufficient mass, the weights being sufficiently below the respective bottom pointed projection so that when the balancing member is placed with the tapered point received in the concave depression at the top of the lower balancing member, a fulcrum effect and stable balancing equilibrium can be achieved.
The device can be constructed in a special form in which the balancing members are intended to be vertically oriented in a particular seriatim order. In such form, the balancing member weights are of a proper mass and at a proper distance below the balancing point or fulcrum so as to be insufficient to provide stable equilibrium for a stack in which a heavier balancing member is positioned out of order thereabove. Stable equilibrium will not be achieved and the stack will fall causing the child to try again until the balancing members are in proper order.
