Abstract
Abstract On this safety pyramidal toy spindle fitted in a separate base similar components formed with a central hole are adapted to be placed in order to constitute an educational game for small children; the pyramid formed by the components being crowned by an allegorical head or similar character. This spindle is a one-piece member of non-toxic material having a flexibility sufficient to permit the bending of its tip down to the level of the base bottom, the spindle resuming its position substantially perpendicular to the base when the pressure exerted at any point along the spindle is released. The cross-sectional shape of the spindle being substantially that of a greek cross with reinforcing ribs.
