摘要

A recreational and psychotechnical device to exercise the skill and appreciate the reflexes, which essentially comprises a flat and smooth circular track of variable inclination provided with a series of circular perforations of equal diameter, arranged arbitrarily on its surface, and a fixed annular frame provided of another series of perforations equal to each other and to those of the track; this set of track and frame is arranged above a frustoconical cuvette centered with a lower tubular column that serves as a guide to a piston topped by an upper frustoconical tape that when ascending the piston happens to coincide and fit with a central perforation of the circular platform flat the flat circular platform can be tilted in any direction by means of lateral controls acting on respective lever systems that attack said platform below and eccentrically; the central piston is subjected to the reaction of a spring that tends to keep it high and with the terminal cap adjusted to the central hole of the track, and can be lowered optionally acting on a control lever that projects laterally from the base.
