Abstract (en)
[origin: EP0045963A1] The construction set is comprised of synthetic material elements capable of being assembled. On their upper side, the elements have a protruding portion and, in their lower side, a tightening portion. The assembly of two construction elements is obtained by introducing, under pressure, the protruding part of one of the elements into the tightening part of the other element. The material of the construction elements is a synthetic material, flexible, solid, friction resistant, undeformable and hygienic, as for example polyethylen. The tightening part (1) and the protruding part (2) are coaxial and comprised by sleeve-shaped walls. On their outer face, the elements are provided with round corners (9), and in their inner portion, with reinforcement walls (6).
