CAMPO DE LA INVENCIÓNFIELD OF THE INVENTION
La presente invención se refiere a mejoras en un sistema móvil para realizar prácticas de laboratorio.The present invention relates to improvements in a mobile system for performing laboratory practices.
Más particularmente, se refiere a mejoras en la estructura mecánica y demás componentes de un sistema móvil para realizar prácticas de laboratorio.More particularly, it refers to improvements in the mechanical structure and other components of a mobile system to perform laboratory practices.
ANTECEDENTES DE LA INVENCIÓN Existe actualmente la necesidad de llevar hasta los salones de clase desde los niveles básicos hasta los niveles superiores de estudio, sistemas móviles en los cuales se puedan llevar a cabo diferentes experimentos para la enseñanza de ciencias tales como la física, la química y la biología entre otras. Se han hecho intentos en desarrollar gabinetes móviles que contengan un amplio equipo para la realización de muy variados experimentos en dichas áreas de la ciencia con fines de enseñanza.BACKGROUND OF THE INVENTION There is currently a need to bring classrooms from the basic levels to the upper levels of study, mobile systems in which different experiments for teaching science such as physics, chemistry can be carried out and biology among others. Attempts have been made to develop mobile cabinets that contain extensive equipment for conducting varied experiments in these areas of science for teaching purposes.
Por ejemplo, en las solicitudes de patente Brasileñas Nos.For example, in Brazilian patent applications Nos.
BR8100060U y BR8100289U publicadas el 3 de septiembre de 2002 y el 9 de septiembre de 2003, respectivamente, se divulga un gabinete de laboratorio móvil para realizar experimentos que comprende un gabinete monobloque con tapa superior antiderrapante, puertas y ruedas que puede incluir equipos tales como una bomba de agua, un lavabo, un depósito para agua, un sistema de drenaje para residuos, un compresor de aire, una fuente ininterrumpida de energía y un sistema de protección contra sobrecargas y cortos circuitos .BR8100060U and BR8100289U published on September 3, 2002 and September 9, 2003, respectively, a mobile laboratory cabinet is disclosed to conduct experiments comprising a monobloc cabinet with a non-skid top cover, doors and wheels that may include equipment such as a water pump, a washbasin, a water tank, a waste drainage system, an air compressor, an uninterrupted source of energy and an overload protection system and short circuits.
Aunque dicho gabinete puede ser funcional, presenta graves fallas en su estructura que lo hacen deficiente en la seguridad del mismo al ser desplazado de un sitio a otro a fin de cumplir su función de ser móvil. Asimismo, presenta deficiencias graves en la superficie sobre la cual se llevan a cabo los experimentos ya que no cuenta con medios seguros para que principalmente los residuos líquidos sean desechados de manera apropiada y segura. Existe también la solicitud de patente Alemana No. DE200520003038U publicada el 16 de junio de 2005, la cual describe un gabinete de laboratorio móvil para demostraciones educativas por ejemplo de reacciones químicas que tiene un sistema de extracción en la pared lateral interna. Sin embargo, dicho gabinete no cuenta con compartimentos adecuados para guardar diferentes equipos o kits para la realización de diferentes experimentos aparte de experimentos químicos, por lo que su utilidad está enormemente limitada.Although this cabinet can be functional, it presents serious flaws in its structure that make it deficient in its security when being moved from one place to another in order to fulfill its function of being mobile. It also has serious deficiencies on the surface on which the experiments are carried out since it does not have safe means so that mainly liquid waste is disposed of properly and safely. There is also the German patent application No. DE200520003038U published on June 16, 2005, which describes a mobile laboratory cabinet for educational demonstrations for example of chemical reactions having an internal side wall extraction system. However, said cabinet does not have adequate compartments to store different equipment or kits for carrying out different experiments apart from chemical experiments, so its usefulness is greatly limited.

It is yet another object of the invention to provide said mobile laboratory practice system with a sealed compartment for storing a portable gas burner together with its burner. Said sealed compartment avoids risks of flame or explosion by keeping away a possible gas leak from any chemical reagent. Said sealed compartment comprises its own lock and is located inside the main compartment of the cabinet protecting it from any external impact.
