Abstract
An improved three-dimensional combination toy may comprise a central part, a plurality of guide canopies installed above the central part to form guide spaces, (the guide canopies being laterally spaced apart from one another such that the spaces between the edges of adjacent guide canopies define guide tracks), seven movable blocks (each provided with a slide piece dimensioned to slide within and be retained by the guide spaces and attached to its block via an inwardly projecting slide leg free to move within the guide tracks) and a fixed block fastened to the central part. Preferably, a slide piece insertion opening is defined (by means of cutouts provided in the relevant canopy corners) at one particular rest position where a particular three of said guide canopies are adjacent to one another. The guide canopies may first be attached to the central part; the seven movable blocks may then be assembled with their respective slide pieces inserted into the guide spaces via the slide piece insertion opening, and finally the fixed block may be fastened to the central part above the slide piece insertion opening.
