Pupitre versátil visual y posturalmente ergonómico Versatile visual and posturally ergonomic desk

SECTOR DE LA TÉCNICA SECTOR OF THE TECHNIQUE

La presente invención se refiere encuadra dentro del sector de mobiliario para trabajo, en particular se refiere a mobiliario para entornos de enseñanza y aprendizaje. De forma más concreta, se refiere a un pupitre con ergonomía visual y postural. The present invention refers to within the furniture sector for work, in particular it refers to furniture for teaching and learning environments. More concretely, it refers to a desk with visual and postural ergonomics.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Los escritorios habituales usados en aula se pueden encontrar en forma mesa plana con una silla asociada a la misma. También se utilizan mesas unidas al asiento para una fácil disposición en grupos de trabajo colaborativo. Estas mesas son de una medida fija para un grupo de alumnos de una edad determinada pero de estaturas diferentes. Las sillas tienen ei mismo problema impidiendo una incorrecta postura y ergonomía cuando estas personas realizan tareas habituales de estudio en clase Cincuenta minutos en estas condiciones durante 6 horas de media durante 5 olas lectivos perjudica, tanto la condición física de cada alumno, como también la adaptación visual con problemas de visión binocular cuando se inclina papel o cabeza para realizar la lectura, escritura o dibujos evitando problemas de visión doble, bcrrosidad, lagrimeo, enrojecimiento de ios ojos y otros, impidiendo el mejor rendimiento desde el punto de vísta optométríco. The usual desks used in the classroom can be found in a flat table with a chair associated with it. Tables attached to the seat are also used for easy arrangement in collaborative work groups. These tables are of a fixed size for a group of students of a certain age but of different statures. The chairs have the same problem preventing incorrect posture and ergonomics when these people perform usual tasks of study in class Fifty minutes in these conditions for 6 hours on average during 5 waves of classes harms both the physical condition of each student, as well as the adaptation visual with binocular vision problems when tilting paper or head to perform reading, writing or drawings avoiding problems of double vision, bcrrosidad, lachrymation, redness of the eyes and others, preventing the best performance from the point of optometric sight.

Un problema adicional viene dado por la iluminación de las aulas que puede dar lugar a sombras en el texto de trabajo y la pérdida de contraste por la disposición de los focos sin potencia suficiente para permitir la mejor luminosidad. An additional problem is given by the lighting of the classrooms that can give rise to shadows in the text of work and the loss of contrast by the arrangement of the spotlights without sufficient power to allow the best luminosity.

La combinación entre la mesa y la silla produce desequilibrios adicionales en forma de distancias demasiado cortas al texto, tropiezos con las piernas por ser muy bajas las mesas o altas las sillas, incomodidad por respaldo, columnas Inclinadas por falta de inclinación de las mesas y otras similares. Por tanto, sería deseable disponer de un equipo ligero, versátil y con tecnología avanzada e iluminación autónoma independiente de la del aula. The combination between the table and the chair produces additional imbalances in the form of distances too short to the text, trips with the legs because the tables are too low or the chairs are high, discomfort due to backrest, columns inclined due to the lack of inclination of the tables and other Similar. Therefore, it would be desirable to have a light, versatile equipment with advanced technology and autonomous lighting independent of the classroom.

En esta invención se propone un escritorio que permite modificar la altura, inclinación e iluminación en función de las necesidades del usuario. Además, el equipo puede ser fabricado con materiales ligeros para poder ser transportado y puede incorporar un equipo informático. In this invention a desk is proposed that allows to modify the height, inclination and lighting according to the needs of the user. In addition, the equipment can be manufactured with lightweight materials to be transported and can incorporate a computer equipment.

EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION

El pupitre está formado por dos elementos principales: un tablero (1) y un asiento (4) unidos por, ai menos, una barra formada, a su vez, por dos partes ensambladas: una parte flexible (12) - unida ai tablero por un cabezal (11 ) que permite la vascularización de la tabla y su fijación - y una parte fija exlensibíe (13) unida al asiento que permite alejar o acercar el asiento al tablero para acopiar eí cuerpo según las características ergonómicas del usuario. The desk is formed by two main elements: a board (1) and a seat (4) joined by, at least, a bar formed, in turn, by two assembled parts: a flexible part (12) - attached to the board by a head (11) that allows the vascularization of the table and its fixation - and a fixed part (13) attached to the seat that allows to move the seat closer or closer to the board to collect the body according to the ergonomic characteristics of the user.

El tablero (1 ) lleva incorporado un espacio para adherir una tableta digital con un sistema operativo y aplicaciones específicas para enseñanza con conexión wifi y otros sistemas de conexión inalámbrica. Además, el tablero se puede doblar en el centro de su estructura: esta doblez (3) se consigue con bisagras. El tablero cuenta con dos laterales de LED (10) que se pueden encender y variar en intensidad y color, con conexión a una batería incorporada en la propia bese, incrustada y tapada. The board (1) incorporates a space to attach a digital tablet with an operating system and specific applications for teaching with Wi-Fi connection and other wireless connection systems. In addition, the board can be folded in the center of its structure: this fold (3) is achieved with hinges. The board has two LED sides (10) that can be switched on and vary in intensity and color, with connection to a built-in battery, embedded and covered.

El asiento (4) se divide en varias partes para posibilitar su variación en altura con la posadera (5) en base a un tabique hidráulico (6) apoyado sobre tres patas (7) y con abrazadera con mando (8) que permite bloquear la altura adecuada también del vastago superior (9) que permita poner el respaldo en una posición de apoyo relajante. The seat (4) is divided into several parts to allow its variation in height with the innkeeper (5) based on a hydraulic partition (6) supported on three legs (7) and clamp with control (8) that allows to block the suitable height also of the upper rod (9) that allows to put the backrest in a position of relaxing support.

Todos ios elementos pueden estará fabricados de un material ligero (metal o plástico) para que ei escritorio pueda ser transportado con facilidad. All the elements can be made of a light material (metal or plastic) so that the desk can be transported easily.

Eí pupitre puede es de uso individual pero con posibilidad de sincronización para combinar equipos similares en caso de trabajo en grupos.
