La presente memoria descriptiva se refiere, como su título indica, a un teclado desechable y reciclable destinado a ser utilizado en hoteles, residencias, hospitales y colectividades para el control o la introducción de datos en equipos electrónicos o informáticos, caracterizado porque está constituido de tal forma que es una estructura fina y económica, desechable y reciclable, susceptible de ser entregado para su uso personal a cada cliente de un hotel, paciente de un hospital, usuario de una residencia, etc… o bien utilizados para renovarlos periódicamente en aquellos entornos médicos, quirúrgicos o industriales donde la higiene y la esterilización dificulte el uso de teclados convencionales. This description refers, as its title indicates, to a disposable and recyclable keyboard intended for use in hotels, residences, hospitals and communities for the control or introduction of data in electronic or computer equipment, characterized in that it is constituted of such form that is a fine and economical structure, disposable and recyclable, capable of being delivered for personal use to each client of a hotel, patient of a hospital, user of a residence, etc ... or used to renew them periodically in those medical environments , surgical or industrial where hygiene and sterilization make it difficult to use conventional keyboards.

En la actualidad son ampliamente conocidos múltiples y variados tipos de teclados utilizados en variados entornos, como por ejemplo mandos a distancia de televisión, equipos musicales, aire acondicionado, teclados de ordenadores, móviles, teclados de control de equipos médicos o quirúrgicos. En este tipo de equipos es frecuente, por ejemplo en el caso de hoteles, residencias, hospitales, que dichos teclados sean utilizados sucesivamente por muchos clientes, usuarios o pacientes. Esto plantea unos serios problemas de higienización, desinfección y limpieza, robos, perdidas, etc. debido principalmente a que el elevado coste de estos equipos obliga a utilizarlos repetidas veces. At present, multiple and varied types of keyboards used in various environments are widely known, such as television remote controls, musical equipment, air conditioning, computer keyboards, mobiles, medical or surgical equipment control keyboards. In this type of equipment it is frequent, for example in the case of hotels, residences, hospitals, that said keyboards are used successively by many clients, users or patients. This raises serious problems of sanitation, disinfection and cleaning, theft, loss, etc. mainly because the high cost of these equipment requires them to be used repeatedly.

Son comúnmente conocidos y se han empleado tradicionalmente teclados planos o extraplanos, que facilitan la limpieza frente a los electromecánicos, tal y como podemos encontrar recogido en las patentes JP 11134092 “Teclado de tipo plano”, ES 2065360 “Teclado de láminas” y ES 2000729 “Teclado con estructura laminar”, pero siguen presentando problemas de desinfección e higienización, a la par que su alto coste económico hace imposible que sean de un solo uso. Flat or extra-flat keyboards are commonly known and have been used traditionally, which facilitate cleaning against electromechanics, as can be found in JP 11134092 "Flat type keyboard", ES 2065360 "Sheet keyboard" and ES 2000729 "Keyboard with laminar structure", but still presenting problems of disinfection and sanitation, while its high economic cost makes it impossible for them to be of a single use.

Se han intentado utilizar asimismo una gran variedad de protecciones higiénicas flexibles, desechables, que se aplican sobre teclados convencionales, tales como las descritas en las patentes GB 2393146 “Cubierta antibacteriana desechable para un teclado de ordenador y un ratón”, CN 201355477 “Película sanitaria desechable utilizada para teclado de ordenador”, CN 201130348 “Cubierta higienizadora para teclado”, US 5944432 “Dispositivo para suministrar cubiertas sanitarias desechables para teclados” y US 20010041088 ”Embalaje cubierta para teclado de ordenador”, pero son una solución costosa, no ecológica al tratarse de materiales no biodegradables, y que además no garantiza una absoluta desinfección del teclado. Attempts have also been made to use a wide variety of flexible, disposable hygienic protections, which are applied to conventional keyboards, such as those described in GB 2393146 "Disposable antibacterial cover for a computer keyboard and mouse", CN 201355477 "Sanitary film disposable used for computer keyboard ”, CN 201130348“ Hygienic keyboard cover ”, US 5944432“ Device for supplying disposable sanitary keyboard covers ”and US 20010041088“ Computer keyboard cover packaging ”, but they are an expensive, non-ecological solution to they are non-biodegradable materials, and that also does not guarantee an absolute disinfection of the keyboard.

También podemos encontrar realizaciones extraplanas y flexibles, como por ejemplo la descrita en la Patente CA 2372706 “Matriz de teclado completamente flexible”, susceptible de realizarse sobre tela o papel, pero presenta el problema de que el mecanismo de funcionamiento se basa en cadenas metálicas, lo cual impide un inmediato reciclado del reciclado, debiendo separarse en centros especializados de reciclado y no por los usuarios las partes metálicas de las no metálicas, con el consiguiente encarecimiento del proceso. We can also find extra-flat and flexible embodiments, such as the one described in Patent CA 2372706 "Fully flexible keyboard matrix", which can be made on fabric or paper, but presents the problem that the operating mechanism is based on metal chains, which prevents an immediate recycling of recycling, and the metallic and non-metallic parts must be separated in specialized recycling centers and not by users, with the consequent increase in the cost of the process.

Para solventar la problemática existente en la actualidad de contagio por gérmenes nocivos para la salud de las personas, en cuanto la higiene y aislamiento sanitario en colectividades o entornos multiusuario, y proporcionar una solución que mejore o sea alternativa a las existentes, se ha ideado el teclado desechable y reciclable objeto de la presente invención, el cual está formado por dos capas de material biodegradable con tinta conductora ecológica y/o finas láminas de aluminio, separados opcionalmente por una capa aislante preferentemente de material vegetal en forma de pintura, y con otras capas complementarias también de de material biodegradable. La capa superior dispone de unos troquelados parciales, a modo de penínsulas, o bien de unos termoconformados que crean unas teclas accionables con el dedo. To solve the current problem of contagion by germs harmful to people's health, in terms of hygiene and sanitary isolation in multi-user communities or environments, and provide a solution that improves or is alternative to existing ones, it has been devised disposable and recyclable keyboard object of the present invention, which is formed by two layers of biodegradable material with ecological conductive ink and / or thin sheets of aluminum, optionally separated by an insulating layer preferably of plant material in the form of paint, and with other complementary layers also of biodegradable material. The upper layer has partial die cuts, like peninsulas, or thermoforming that create keys that can be operated with the finger.

De esta forma el teclado es una estructura ergonómica fina y económica, desechable y reciclable, susceptible de ser entregado para su uso personal a cada cliente de un hotel, paciente de un hospital, personal médico, usuario de una residencia, etc… o bien utilizados para renovarlos periódicamente en aquellos entornos médicos, quirúrgicos o industriales donde la higiene y la esterilización dificulte el uso de teclados convencionales. In this way the keyboard is a fine and economical ergonomic structure, disposable and recyclable, capable of being delivered for personal use to each client of a hotel, patient of a hospital, medical staff, user of a residence, etc ... or well used to renew them periodically in those medical, surgical or industrial environments where hygiene and sterilization make it difficult to use conventional keyboards.

Entre los principales usos de esta invención se encuentran todos aquellos equipos electrónicos susceptible de ser utilizados a distancia y por múltiples personas, en hoteles, residencias, hospitales, colectividades, como por ejemplo mando a distancia de televisión, mando a distancia de aire acondicionado, mando a distancia de un equipo musical, teclado de un equipo informático, teclado de un teléfono móvil, teclado de un dispositivo médico o quirúrgico, etc… Among the main uses of this invention are all those electronic equipment that can be used remotely and by multiple people, in hotels, residences, hospitals, communities, such as television remote control, air conditioning remote control, remote control remote control of a musical equipment, keyboard of a computer equipment, keyboard of a mobile phone, keyboard of a medical or surgical device, etc ...
