  • this includes the above Puzzle a transparent puzzle support, illuminated from below with a suitable light source, on which the individual puzzle elements can be arranged. The lighting from below shows whether the individual puzzle elements are correctly assembled or not.
  • a disadvantage of these known three-dimensional puzzles is that they are only insufficiently suitable as advertising media or representational bodies. On the one hand, they would have to be sufficiently complicated to satisfy the play instinct of the human being, and on the other hand, the disassembled puzzle should not give such a complicated impression that it discourages a potential customer from playing with the puzzle, that is, it covers up the human instinct to play.
  • the puzzle consists of a certain number of puzzle bodies, which result from plane cuts of a tetrahedron. These flat steps result in comparatively simple geometric bodies which have a plurality of planar surface surface pigments and which are parts of the surface of the underlying tetrahedron.

  • the puzzle becomes more or less complicated and can therefore be difficult to the degree of a specific user group or when used as an advertising medium or presentation body for a specific group of buyers.
  • the puzzle bodies are all of the same shape. This can be achieved simply in that the cuts through which the puzzle bodies are generated by the tetrahedron and the resulting partial bodies are always placed in such a way that two identical bodies are created. Since the puzzle bodies consist of identical parts or parts of the same shape, the puzzle parts into which the puzzle bodies are broken down only consist of two differently shaped parts. I.e. the entire puzzle consists of a certain number of
  • Puzzle pieces with a first shape and the same number of puzzle pieces with a second shape are identical parts or with only two different puzzle pieces naturally also leads to considerable advantages in production, since the production machines only have to be designed for two different parts.
  • the individual puzzle bodies are hollow, so that the individual puzzle pieces each consist of at least two plates arranged at an angle to one another. So that these puzzle pieces can be put together to form the respective puzzle body, the abutting edges of the puzzle pieces must be beveled. Hollow puzzle pieces have the advantage that they can be used as containers. With appropriate dimensioning of the puzzle or the puzzle body, for example, the product for which the advertisement is to be advertised can be included in the puzzle bodies (claim 6).

Abstract

Un puzzle tridimensionnel se compose d'une pluralité de pièces (60-67) qui peuvent à leur tour être décomposées en deux parties (68, 69). Dans leur état assemblé, les pièces forment un tétraèdre. Selon un mode préférentiel de réalisation, les faces des pièces qui sont à l'extérieur du tétraèdre assemblé sont pourvues de parties d'un puzzle holographique. Lorsque l'on assemble correctement le puzzle tridimensionnel composé des pièces et éléments, le puzzle holographique est lui aussi correctement assemblé. Selon un mode préférentiel de réalisation, les pièces du puzzle sont creuses, de sorte que l'on peut également emboîter les uns dans les autres une pluralité de ces puzzles.
