发明名称 Deformable toy building elements - are made in basic geometric or letter shapes in both solid and hollow form from elastic deformable foam material
摘要 <p>The deformable toy building units belong together. The toy building units have the form of basic geometric elements and of letters with type measurements and are available both in solid and hollow form. The toy building units have a surface with a considerable degree of roughness and consists of a foam material which is to a large extent elastically deformable. The building units are punched out from a plate of foam material and at least some of the hollow formed units can be turned inside out.</p>
