Escalera adaptable para paso de minusválidos.Adaptable ladder for passing disabled.
La presente invención se refiere a una escalera adaptable para paso de minusválidos, prevista para permitir que los minusválidos que se desplazan en silla de ruedas puedan pasar de un nivel a otro de manera autónoma, sin ayuda de terceros y sin ningún tipo de dificultad. El dispositivo es igualmente válido para madres con carritos, ya sea de bebés, de la compra, etc, o para cualquier otra aplicación similar.The present invention relates to a ladder adaptable for disabled people, intended to allow disabled people who move in a wheelchair can pass from a level to another autonomously, without the help of third parties and without any type of difficulty The device is equally valid for mothers with carts, whether for babies, shopping, etc, or for any Another similar application.
El objeto de la invención es transformar una escalera en una plataforma elevable para que la silla de ruedas de minusválidos pueda salvar el obstáculo infranqueable que supone la escalera en posición de uso normal. La plataforma en que es transformable la escalera también puede descender y permitir con ello que el minusválido en su silla de ruedas pueda acceder tanto al nivel o plano superior como al nivel o plano de suelo inferior.The object of the invention is to transform a ladder on a lifting platform so that the wheelchair of disabled people can overcome the insurmountable obstacle that the ladder in normal use position. The platform on which it is transformable the ladder can also descend and allow with this means that the disabled person in his wheelchair can access both the upper level or plane as at the lower level or floor plan.
La barrera arquitectónica que suponen las escaleras para minusválidos que se desplazan en silla de ruedas, limitan enormemente la movilidad de éstos, ya que cuando en su trayectoria se encuentran con una escalera, resulta imposible salvar esta barrera.The architectural barrier that the disabled stairs that move in a wheelchair, greatly limit their mobility, since when in their path meet a ladder, it is impossible to save This barrier.
Ante dicho problema se adoptan medidas tales como rampas, elevadores específicos concebidos al efecto, etc, como medios alternativos a las escaleras para posibilitar el tránsito de los minusválidos en silla de ruedas, entre diferentes niveles, aunque dichas soluciones únicamente resuelven en parte la problemática.Faced with this problem, such measures are taken as ramps, specific elevators designed for this purpose, etc., as alternative means to the stairs to enable the transit of the disabled in a wheelchair, between different levels, although these solutions only partially solve the problematic
No obstante, se conocen sistemas basados en la construcción de escaleras transformables, en las que sus escalones pueden adoptar una posición coplanaria, permitiendo de este modo el acceso a una plataforma que se puede elevar y/o descender para poder situarse en correspondencia con el nivel de un piso superior o con el nivel de un piso inferior, y con ello permitir que la silla de ruedas de minusválido pueda transitar sin problemas.However, systems based on the construction of transformable stairs, in which its steps they can adopt a coplanar position, thus allowing the access to a platform that can be raised and / or lowered to be able to be in correspondence with the level of an upper floor or with the level of a lower floor, and thereby allow the chair to Disabled wheels can travel smoothly.
Concretamente, en la Patente Europea 2147559 se describe un conjunto de escalera/aparato elevador para personas con la finalidad expuesta, en donde los peldaños de la escalera están relacionados con unos elementos articulados formando un mecanismo que posibilita disponer todos los peldaños en el mismo plano, para que en combinación con una plataforma asociada al conjunto del mecanismo, permitir el paso de la silla de ruedas de un nivel a otro, previo posicionado de la silla en la plataforma inicial a través de la plataforma formada por los escalones en su posición coplanaria.Specifically, in European Patent 2147559 it is describes a set of stairs / lifting apparatus for people with the stated purpose, where the stair steps are related to articulated elements forming a mechanism which makes it possible to arrange all the steps in the same plane, to that in combination with a platform associated with the whole of the mechanism, allow the passage of the wheelchair from one level to another, after positioning the chair on the initial platform to through the platform formed by the steps in position coplanar
En esta Patente Europea se describen varias alternativas en lo que respecta a la materialización de la escalera y a los elementos para posicionar los peldaños de una u otra manera, aunque siempre con el denominador común de una enorme complejidad del conjunto de elementos que intervienen, vinculación y forma de llevar a cabo el posicionado de los peldaños, lo que unido a la plataforma inicial supone una elevada ocupación volumétrica y por lo tanto mas espacio para la implantación de la escalera, lo que resulta inviable en determinados lugares.This European Patent describes several alternatives in regards to the materialization of the ladder and to the elements to position the steps in one way or another, although always with the common denominator of enormous complexity of the set of elements involved, linking and form of carry out the positioning of the steps, which together with the initial platform supposes a high volumetric occupation and therefore much more space for the implementation of the staircase, which It is unfeasible in certain places.
La escalera que se preconiza ha sido concebida para resolver la problemática anteriormente expuesta, estando además realizada de forma sencilla, simple y con una estructura que ocupa un espacio reducido, lo que posibilita su implantación en cualquier parte en que sea necesaria su utilización.The ladder that has been recommended has been conceived to solve the problem described above, being also made in a simple, simple way and with a structure that occupies a reduced space, which allows its implementation in any part in which its use is necessary.
La escalera adaptable de la invención se constituye mediante una pluralidad de peldaños, como es convencional, pero facultados en este caso con la capacidad de desplazarse verticalmente en sentido ascendente y/o descendente, de forma independiente, y sincronizada, para establecer una plataforma a la que podrá acceder la silla de ruedas de un minusválido, para que éste pueda situarse en un nivel superior o en un nivel inferior respecto del suelo, previo desplazamiento ascendente y/o descendente de la comentada plataforma formada por dichos peldaños móviles.The adaptable ladder of the invention is constitutes by a plurality of steps, as it is conventional, but empowered in this case with the ability to move vertically upward and / or downward, from independently, and synchronized, to establish a platform which can be accessed by the wheelchair of a disabled person, for that it can be placed at a higher level or at a lower level with respect to the ground, after ascending and / or descending displacement of the commented platform formed by said mobile steps.
A partir de estas características, la escalera
de la invención presenta una serie de particularidades de las que se
derivan las ventajas referidas con anteriori-
dad.From these characteristics, the ladder of the invention presents a series of particularities from which the advantages referred to above are derived.
dad
Una de las características de la escalera de la invención consiste en que la estructura de elevación/descenso de cada peldaño es físicamente independiente respecto de los restantes, si bien los mismos estarán sincronizados, y está materializada, en cada caso, con un especie de mecanismo de tijera cuyos brazos son accionados para elevar y/o descender el respectivo peldaño, mediante un mecanismo constituido por un motor eléctrico con un husillo que extiende o retrae la tijera soporte del peldaño, elevando o descendiendo éste.One of the characteristics of the staircase of the invention is that the lifting / lowering structure of each step is physically independent from the rest, although they will be synchronized, and it is materialized, in each case, with a kind of scissor mechanism whose arms are actuated to raise and / or descend the respective step, by a mechanism consisting of an electric motor with a spindle that extend or retract the step support scissors, raising or descending this one.
Evidentemente ese mecanismo de accionamiento puede ser sustituido por unos medios hidráulicos y/o neumáticos que realicen la misma función. De igual manera, es posible disponer un mecanismo alternativo con la ubicación de la maquinaria albergada en las cajas laterales, de manera que se evite la ocupación del fondo bajo la escalera.Obviously that drive mechanism it can be replaced by hydraulic and / or pneumatic means that Perform the same function. Similarly, it is possible to arrange a alternative mechanism with the location of machinery housed in the lateral boxes, so that the occupation of the fund is avoided down the stairs.
Mediante un adecuado control de movimiento de los distintos motores de accionamiento de los distintos peldaños, se consigue que cada uno de éstos baje hasta el nivel extremo inferior, es decir hasta quedar coplanarios con el plano del escalón inferior y empotrado en el suelo, quedando todos los peldaños coplanariamente para establecer una plataforma a nivel del suelo, a la que puede acceder sin problemas una silla de ruedas de minusválidos o una persona impedida, de manera que manteniendo la horizontalidad de tal plataforma, ésta puede ocupar, por ascenso, el nivel superior mediante el accionamiento simultáneo de todas las tijeras y con la misma intensidad, permitiendo por lo tanto al minusválido acceder a ese nivel superior.Through proper movement control of the different drive motors of the different steps are get each of these down to the lower extreme level, that is to say until coplanaries remain with the plane of the lower step and embedded in the ground, leaving all the steps coplanarly to establish a ground level platform, to which you can seamlessly access a disabled wheelchair or a handicapped person, so that maintaining the horizontality of such platform, it can occupy, by promotion, the upper level by simultaneous operation of all scissors and with the same intensity, thus allowing the disabled to access That higher level.
Obviamente, el tránsito de un nivel superior a otro inferior se efectuará a la inversa.Obviously, transit from a level higher than another lower one will be done in reverse.
Por último decir que la escalera se puede complementar con una barandilla articulada, de protección o seguridad, para casos en los que exista riesgo de caída frontal durante las operaciones de elevación y/o descenso de la plataforma formada por el conjunto de peldaños de la propia escalera.Finally say that the ladder can be complement with an articulated, protective railing or safety, for cases where there is a risk of frontal fall during platform lifting and / or lowering operations formed by the set of steps of the ladder itself.
Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

La figura 5.- Corresponde a un detalle en perspectiva de parte del mecanismo de accionamiento de la tijera de cada peldaño, constituida fundamentalmente por un motor y un husillo.Figure 5.- Corresponds to a detail in perspective of part of the scissor drive mechanism of each step, consisting essentially of an engine and a spindle
La figura 6.- Muestra una representación correspondiente a una vista lateral de la tijera de un peldaño en posición plegada.Figure 6.- Shows a representation corresponding to a side view of the scissors of a step in folded position.
En las figuras referidas puede verse una escalera (1) con una pluralidad de peldaños (2) capacitados de desplazarse independientemente en sentido vertical. Cada peldaño (2) está soportado por una estructura de tijera (3) que es extraíble y extensible para descender y/o ascender, respectivamente.In the referred figures you can see a ladder (1) with a plurality of steps (2) capable of move independently vertically. Each step (2) is supported by a scissor structure (3) that is removable and extensible to descend and / or ascend, respectively.
Dichas estructuras de tijera (3) son accionadas por un mecanismo formado preferentemente por un motor (4) y un husillo (5), de manera que éste discurre a través de una tuerca ubicada y fijada en un carro de desplazamiento formado por un bloque central (6) que incorporará la correspondiente tuerca de paso del husillo (5), con un brazo transversal (7) en cuyos extremos están establecidas articulaciones (9) de la tijera (3), de manera que dependiendo del sentido de giro del husillo (5) y por lo tanto del sentido de desplazamiento del referido carro (6), la correspondiente tijera (3) se extenderá o se retraerá para producir, en acción de extensibilidad, la elevación del respectivo peldaño (2), mientras que en la acción de retraimiento se producirá el descenso del peldaño (2). Como es evidente y se puede ver en la figura 5, las articulaciones (9) incorporan ruedas extremas para deslizamiento por correspondientes guías (11) establecidas en los perfiles laterales de apoyo correspondientes.Said scissor structures (3) are driven by a mechanism preferably formed by a motor (4) and a spindle (5), so that it runs through a nut located and fixed in a carriage formed by a block central (6) that will incorporate the corresponding nut spindle (5), with a transverse arm (7) at whose ends are established joints (9) of the scissors (3), so that depending on the direction of rotation of the spindle (5) and therefore the direction of travel of said carriage (6), the corresponding scissors (3) will extend or retract to produce, in action of extensibility, the elevation of the respective step (2), while that in the retraction action the descent of the step (2). As is evident and can be seen in Figure 5, the Joints (9) incorporate extreme wheels for sliding by corresponding guides (11) established in the side profiles corresponding support.
De acuerdo con las características referidas, cuando la escalera (1) se encuentra en posición de uso como se ve en las figuras 1 y 2, y en donde puede apreciarse además que el peldaño (2) está enrasado con el suelo (8), como se representa en las figuras 1 y 3, en el caso de querer pasar a nivel superior por parte de un minusválido en una silla de ruedas, será necesario accionar los motores (4) de accionamiento de las distintas estructuras de tijera (3) soporte de los peldaños (2), efectuándose lógicamente un control del movimiento de los motores para conseguir que todos los peldaños (2) se sitúen coplanariamente al mismo nivel, formando una plataforma inferior (10) enrasada con el peldaño inferior (2), como se ve en la figura 3, en cuya plataforma se puede ubicar una silla de ruedas de minusválido para posteriormente elevar la plataforma referida (10), es decir simultáneamente todos los peldaños (2) con el control ya referido de los motores, lo que se puede conseguir mediante la oportuna sincronización, alcanzando dicha plataforma (10) el nivel superior al que puede directamente acceder y transitar en el mismo la silla de ruedas.According to the characteristics mentioned, when the ladder (1) is in the position of use as seen in Figures 1 and 2, and where it can also be seen that the step (2) is flush with the ground (8), as depicted in the Figures 1 and 3, in the case of wanting to pass to a higher level on the part of a disabled person in a wheelchair, it will be necessary to operate the drive motors (4) of the different structures of scissors (3) support of the steps (2), logically making a motion control of the engines to get all rungs (2) are coplanarly positioned at the same level, forming a bottom platform (10) flush with the bottom step (2), as it is seen in figure 3, on whose platform a chair can be located of handicapped wheels to later raise the platform referred (10), that is simultaneously all the steps (2) with the aforementioned engine control, which can be achieved through timely synchronization, reaching said platform (10) the level above which you can directly access and transit in it the wheelchair.
