Definitions

  • This invention concerns a children's building block made of injection moulded thermoplastic rubber.
  • the purpose of this invention is the production of building blocks for children under the age of three.
  • building blocks can be press fitted on top of one another, male against female: the elements on the top surface of a block being the male elements which press fit into the bottom cavity (being the female element) of the overlying block.
  • the inventive idea concerns the realization of a game consisting of soft, elastic elements; it is obvious that modules of this kind would in no way be dangerous for small children since if the same fall against the modules accidently they would obviously bend, gradually absorbing the blow and then return to their original shape.
  • the male - female coupling requires very little strength enabling even small children to pull them apart very easily.
  • the invention is set out in claim 1.
  • Polypropylene for example, would be totally ill-suited in this case, regardless of whether this were used during moulding or blowing.
  • blowing procedure can be used only for closed forms (such as dolls, animals, balls) but not for hollow forms, as in the case of building blocks; moreover blown polypropylene is subject to irregular and significant shrinkage when it hardens.
  • PVC is just as unsuitable for manufacturing the element according to the invention for two fundamental reasons; first and foremost because this material is suspected of being toxic to persons, but above all because PVC is also subject to irregular and virtually uncontrollable shrinkage when it hardens; in other words, with this material it would again be impossible to manufacture blocks in identical sizes, this being essential for blocks which are to be coupled together.
  • This manufacturing technique not only ensures good structural results (in that the blocks are sufficiently soft and elastic) but is also inexpensive enough to make it particularly convenient for the production of large scale quantities of the items in question.
  • the preferred embodiment of the construction solution moreover makes it possible to produce the blocks at an industrial level in identical and precise sizes in that thermoplastic rubber is subject to constant shrinkage, which can be estimated with a good degree of accuracy, when it hardens in the mould.
  • moulded blocks can be coupled easily and precisely, male against female, with other blocks, be these blocks manufactured during the same production run or in different production runs.
  • block module according to the invention should also have a conventional cavity at the bottom as well as a series of circular elements projecting from its upper horizontal surface; moreover said modules may be produced in different sizes so as to allow children to build many different shapes and objects.
