<p>The invention relates to a three-dimensional, logical and constructive toy having a regular, semi-regular, spherical or amorphous outer body shape, preferably in the form of a tetrahedron, the body being composed of partial bodies which can be rotated relative to one another, and a six-arm central body with arms disposed at right angles to one another being arranged in the centre-point of the body. According to the invention, the central body (1) consists of three rigid and three rotary arms (2), whose end faces have on one side in each case one large and one small projection and, on the other side, four small projections. Arranged between the arms are twelve sliding segments (3) whose circular outer surface has a guide path, in which correspondingly profiled inner webs of two sliding bodies are guided in the form of a three-sided pyramid so that the eight sliding bodies, which together form a basic body in the shape of a regular octahedron, can be rotated relative to one another about three spatial axes aligned perpendicular to one another. The sliding body (4) has a semicircular opening, to receive in each case three sliding segments (3), and three rectangular cutouts. The outer surface of each sliding body (4) is connected non-detachably to a covering element, four sliding bodies (4) in one tetrahedron consisting of a covering element in the form of a tetrahedron tip (6). <IMAGE></p> |
