  • the structure design allows the deformation thereof and the massive amount of material as well as the very long construction time of the device prevents it from being easily displaced and with reduced costs, after it has been assembled in the said building.
  • the strength offered by this invention is not secure, because of the big parts which it is assembled from, that makes the constructor to use, in his turn, large cross-section elements from said building. Moreover, because of the fact that the assembling of this unit involves the use of a considerable number of bolts, the holes for these bolts drilled in the sectional elements diminishing the strength thereof, and implicitly the strength of the whole structure.

  • the parallelepipedon-shaped frame is a non-deformable structure made of a resistant material. In case of an earthquake, the user has to go to the module located in a certain place inside the room and to open the access door in order to enter the module.
  • this protection module did not take into account the individual use thereof in classrooms in schools and universities or in offices and it cannot be even used this way, namely individually for each person sitting at a desk in the classroom, attending the classes within the teaching process, nor individually by a person in front of a desk in the process of working or studying.
  • the problem solved by the present invention consists in providing individual protection against the consequences of an earthquake, any moment this person occupies a place at a school or university desk or at a desk in a study inside a flat, or in a working room, by rapidly individually manoeuvring the desk in order to find a shelter therein.

Abstract

L'invention concerne une table de bureau parasismique, destinée à protéger les personnes se trouvant à l'intérieur de bâtiments scolaires d'enseignement ou analogues, contre des tremblements de terre, des cyclones, des attaques terroristes, des situations de guerre, et autres catastrophes naturelles ou criminelles. La table de bureau parasismique comprend un cadre de forme parallélépipédique (1) présentant une structure à stabilité dimensionnelle, construite en des matériaux ignifuges, robustes au point de vue structurel, et dotée d'une enveloppe extérieure résistante, pouvant être également aérodynamique. Cinq faces du module sont fermées, et la sixième face mobile (3) est constituée par un panneau coulissant au moyen duquel l'utilisateur peut avoir accès à l'espace protégé et qui présente deux positions : pour l'utilisation normale, en position horizontale, il joue le rôle de support pour les objets personnels et, en position verticale, il forme écran contre les projectiles pouvant blesser l'utilisateur dans des situations d'urgence.
