Abstract
A construction type educational and amusement device having as its basic element a generally spherical hollow module or capsule and adjuncts which may be interconnected and operatively assembled into a large number of different relations to form power-driven vehicles, cranes, propeller-driven floats, air propelled devices and many other assemblies of scientific interest. The capsules of a complete assembly may contain, respectively, an electric motor, gearing of various kinds and types, to form operative simulations. The modules are preferably of clear plastic so that operation may be observed and understood.
Claims28
In an educational and amusement construction type assembly, first and second hollow substantially identical halves forming a generally symmetrical hollow capsule having a polar diameter and an equatorial plane intersecting the mid-point of said polar diameter, normal thereto, said halves having contacting peripheral edges lying in said equatorial plane, and first and second tubular projections extending radially outwardly from said capsule at the respective ends of a first diameter in said equatorial plane, each said projection being formed by matching semi-cylindrical tubular portions each integral with a respective one of said halves and having contacting edge surfaces lying in said equatorial plane.
In a construction type educational and amusement assembly, a plurality of like capsules of regular geometrical form, each comprising first and second identical mating halves and having a polar diameter, an equatorial plane normal to and intersecting the mid-point of said diameter, and contacting peripheral edges disposed in said plane, each said half having first and second semicylindrical projections fixed therewith and extending radially outwardly therefrom at the respective ends of a first diameter in said equatorial plane, each said projection of one half mating with a corresponding projection of the other half to conjointly form a short, open-ended tubular coupling element communicating with the interior of its capsule, and a plurality of tubular connecting sleeves each adapted to receive in its respective ends and with a smooth fit, a pair of said coupling elements of contiguous capsules, to separably and firmly connect the same into a unitary assembly.
