Patent ID: 7963771

Claim:
An experiment and education kit comprising a plurality of units having functional elements, the functional elements comprising a mechanical function element, an optical function element, a detection and measurement function element, or a drive function element, the units being connectable, interlockable or mutually couplable to form a unit constituent body that is an apparatus having a specific function, the kit further comprising a magnetic base and fixtures employing magnetic forces to securedly engage the units against the magnetic base, the fixtures being arranged, when the kit is assembled, alongside sides of the units and comprising peripheral side pressing portions including elongate, elastic slip preventing members protruding from the fixture interiors to the peripheral side pressing portions, the slip preventing members being embedded within an interior of a respective fixture when assembled and are arranged, when the kit is assembled, above a respective top surface of the units and deform across an entirety of a cross-sectional surface area thereof upon being pressed against the top surface of a unit so as to sandwich the units between the slip preventing members and the magnetic base upon secured engagement of the units to the magnetic base, wherein at least two of the units are constructed so as to be detachably secured at arbitrary positions on the magnetic base by means of the fixtures so that the unit constituent body is constructable by mutual positional adjustment of the units detachably secured on the magnetic base.
