Novelty: a prefabricated playground which is an assembled construction formed by connection of prefabricated frames and corridors in factory sites. Constitution: assembled prefabricated frames 1 and corridors 7 of different types assembled in situ via four types of connecting means (11, 12, 13, 14) and double bases 5. For the interconnection of frames, said connecting means engage the housing 2 of the frames. The corridors 7 are created by double bases 5 interconnecting said frames. The composition of the aforementioned four elements (frames, corridors, connecting means and double bases) offer a safe strong construction. Users are protected by the foam 16, the plastic cover 17 covering the metal parts and the material of the corridors, the special plastic nettings 19 and the plastic or metal struts of different types (20, 22, 24) which being tensioned via perforating screws 21 or special plastic fastening means 23 are liable to deter wounding and fall of users. Advantages: easy transport and installation of playgrounds; maximum safety for users. |
