Description

Plataforma auxiliar para escaleras.Auxiliary platform for stairs.

Object of the invention

La presente invención se refiere a una plataforma auxiliar, especialmente concebida para constituir el complemento de una escalera, en especial de una escalera doble o de tijera.The present invention relates to a platform auxiliary, specially designed to be the complement of a ladder, especially a double or scissor ladder.

El objeto de la invención es conseguir una pequeña plataforma que, acoplada a los escalones de la escalera, facilite el posicionamiento o estabilización de determinados objetos utilizables conjuntamente con la escalera, como por ejemplo un cubo de pintura mientras se está pintando.The object of the invention is to achieve a small platform that, coupled to the stair steps, facilitate the positioning or stabilization of certain objects that can be used in conjunction with the ladder, such as a bucket of paint while it is being painted.

Background of the invention

Son conocidas plataformas auxiliares para escaleras del tipo anteriormente citado, como por ejemplo la que muestra la patente europea ES 2 038 809, en la que la plataforma propiamente dicha cuenta con medios de enganche a uno de los peldaños de la escalera y, en oposición a dichos medios de enganche, con una pareja de estribos a través de los que la citada plataforma se cuelga simultáneamente del peldaño inmediatamente superior.Auxiliary platforms are known for stairs of the aforementioned type, such as the one shows the European patent ES 2 038 809, in which the platform proper account with means of hooking to one of the stair steps and, in opposition to said means of hitch, with a pair of stirrups through which the aforementioned platform hangs simultaneously from the step immediately higher.

La plataforma está además concebida fundamentalmente como medio de apoyo para los pies del usuario, en orden a potenciar el confort de la escalera, razón por la cual la plataforma se sitúa entre las dos ramas de la escalera de tijera.The platform is also designed fundamentally as a means of support for the user's feet, in order to enhance the comfort of the stairs, which is why the platform is located between the two branches of the ladder of scissors.

No hace falta ser un experto en la materia para darse perfectamente cuenta que la disposición de la plataforma auxiliar entre las dos ramas de la escalera y los dos estribos laterales a través de los que la misma se cuelga del peldaño superior, crean una especie de "jaula" que rodea a cualquier objeto que se sitúe sobre la plataforma, que hace muy difícil el acceso al mismo. Específicamente si la plataforma auxiliar se utiliza para disponer un cubo de pintura, los propios peldaños de la escalera y los estribos que sujetan la plataforma, constituyen estorbos que afectan a todo el perímetro de dicho cubo y que dificultan de forma muy considerable el acceso a la pintura alojada en el interior del mismo.It is not necessary to be an expert in the field to realize perfectly that the layout of the platform auxiliary between the two branches of the ladder and the two stirrups sides through which it hangs from the step superior, they create a kind of "cage" that surrounds any object placed on the platform, which makes the access to it. Specifically if the auxiliary platform is used to arrange a bucket of paint, the steps of the stairs and stirrups that hold the platform, constitute hindrances that affect the entire perimeter of said cube and that make painting very difficult to access housed inside it.

Aparentemente la solución a este problema sería disponer la plataforma auxiliar hacia fuera, es decir en posición contraria a la prevista en dicha patente europea, pero esto en la práctica no es factible ya que la longitud de los estribos está prevista para que la plataforma auxiliar quede orientada hacia el interior de la escalera, y si se invierte su posición la plataforma adopta una inclinación tan acusada, por resultar los estribos extremadamente cortos, que resultaría inoperante, ya que cualquier objeto depositado sobre la misma tendería a desplazarse por gravedad cayendo finalmente al suelo.Apparently the solution to this problem would be lay the auxiliary platform out, that is, in position contrary to that foreseen in said European patent, but this in the practice is not feasible since the length of the stirrups is provided so that the auxiliary platform is oriented towards the inside the stairs, and if its position is reversed the platform adopts such a steep inclination, as stirrups result extremely short, which would be inoperative, since any object deposited on it would tend to move through gravity finally falling to the ground.

Pero es más, aun diseñando los estribos para este posicionamiento exterior de la plataforma auxiliar, se mantendría parte de la problemática anteriormente expuesta ya que dichos estribos seguirían limitando la accesibilidad a la plataforma, y especialmente limitando el tamaño de los objetos a disponer sobre la misma, cuya anchura no podría en ningún caso ser mayor que el distanciamiento entre tales estribos.But it is more, even designing the stirrups for this external positioning of the auxiliary platform, would remain part of the problem described above since these stirrups would continue to limit accessibility to the platform, and especially limiting the size of the objects to be arranged on the same, whose width could in no case be greater than the distancing between such stirrups.

Description of the invention

La plataforma auxiliar que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, y ello en base a que dicha plataforma, que como en el caso de la citada patente europea está destinada a acoplarse a uno de los peldaños de la escalera, descansa a su vez sobre el peldaño inmediatamente inferior, en lugar de quedar colgada del superior, con lo que la estructura soporte de dicha plataforma queda situada por debajo de ella y no entorpece en absoluto la accesibilidad ni a la plataforma en sí misma ni a los objetos situados encima de ella.The auxiliary platform that the invention proposes solves the problem fully satisfactorily previously exposed, and this on the basis that said platform, which as in the case of the aforementioned European patent is intended to engage one of the steps of the ladder, rest in turn on the immediately lower step, instead of being hanging from the top, so that the support structure of said platform is located below it and does not hinder absolute accessibility neither to the platform itself nor to the objects above it.

De forma más concreta la plataforma se materializa en una chapa metálica que configura una especie de cazoleta invertida, para rigidizar su estructura, con una superficie antideslizante para eliminar el riesgo de deslizamiento sobre ella, con la especial particularidad de que en correspondencia con uno de sus bordes incorpora un faldón descendente a través del que se acopla al peldaño de la escalera elegido, mientras que a través de su borde opuesto se une articuladamente a dos brazos rematados por su extremidad libre en una amplia horquilla redondeada, a través de la que dichos brazos se acoplan al peldaño inmediatamente inferior, actuando como riostras que estabilizan la plataforma propiamente dicha en disposición de trabajo.More specifically the platform is it materializes in a metal sheet that configures a kind of inverted bowl, to stiffen its structure, with a non-slip surface to eliminate the risk of slipping about it, with the special feature that in correspondence with one of its edges incorporates a skirt descending through which it is attached to the stair step chosen, while through its opposite edge it joins articulated with two arms topped by its free limb in a wide rounded fork, through which said arms they attach to the immediately lower step, acting as braces that stabilize the platform itself in work readiness

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas y en especial de la figura 2, puede observarse como la plataforma auxiliar que la invención propone es aplicable a escaleras de tipo tijera en las que se establece un armazón (1) provisto de una pluralidad de peldaños (2) uniformemente distribuidos y al que se unen articuladamente un segundo armazón (3) que actúa como apoyo para el primero, manteniéndolo con la inclinación adecuada, con la colaboración de compás superior (4) en el que forma parte una plataforma (5) integrada en la propia escalera, si bien la invención es igualmente aplicable a escaleras a base de dos armazones idénticos, ambos con peldaños, unidos articuladamente por su extremidad superior y provistos de cualquier medio limitador de apertura o distanciamiento para los mismos.In view of the figures outlined and especially of Figure 2, can be seen as the auxiliary platform that the proposed invention is applicable to scissor-type stairs in that a framework (1) provided with a plurality of steps (2) uniformly distributed and joined articulated a second frame (3) that acts as support for the first, keeping it with the proper inclination, with the upper measure collaboration (4) in which a platform (5) integrated in the ladder itself, although the invention is equally applicable to stairs based on two identical frames, both with steps, joined together by its upper limb and provided with any limiting means of opening or distancing for them.

Pues bien, dicha plataforma auxiliar se materializa en una plataforma propiamente dicha (6), de anchura preferentemente próxima a la longitud de los escalones (2), materializado en una chapa de rigidez apropiada, la cual se potencia dotando a la misma de una combinación a modo de cazoleta invertida, contando en correspondencia con el que ha de ser su borde interno con un faldón vertical y descendente (7), dotado de una ligera inflexión interna (8) en su extremidad libre, faldón destinado al enclavamiento de la plataforma (6) a uno cualquiera de los escalones (2) de la escalera, contando los laterales de dicha plataforma propiamente dicha (6) con prolongaciones extremas (9) contrapuestas al faldón (7) y a las que se unen articuladamente mediante sendos ejes (10), respectivos brazos (11), descendentes, rematados en una horquilla (12) a base de una pareja de amplios arcos extremos (13) fácilmente acoplables a un peldaño de la escalera, relacionados entre sí para constituir un conjunto monopieza mediante rama transversal que relaciona uno de sus extremos y que se corresponde con la propia referencia (12).Well, said auxiliary platform is materializes on a platform proper (6), wide preferably close to the length of the steps (2), materialized in a plate of appropriate stiffness, which power providing it with a bowl-like combination inverted, counting in correspondence with what should be your internal edge with a vertical and descending skirt (7), equipped with a slight internal inflection (8) at its free end, skirt intended for interlocking the platform (6) to any one of the steps (2) of the ladder, counting the sides of said proper platform (6) with extreme extensions (9) opposed to the skirt (7) and to which they are articulated by means of two axes (10), respective arms (11), descending, topped on a fork (12) based on a pair of broad extreme arches (13) easily attachable to a step of the ladder, interrelated to constitute a set monopieza by means of transversal branch that relates one of its extremes and that corresponds to the reference itself (12).

De acuerdo con esta estructuración y como se desprende de la observación de la figura 2, la plataforma propiamente dicha (6), y la superficie operativa estará dotada de perforaciones (14) que rematan protuberancias troncocónicas, para potenciar su agarre, y es susceptible de engancharse a través del faldón (7) sobre un peldaño de la escalera (1), y simultáneamente apoyar a través de los brazos (11) sobre el peldaño inmediatamente inferior, adoptando una posición sensiblemente horizontal, proyectada hacia fuera, que permite tanto la disposición sobre la misma de una persona como de cualquier objeto, quedando éste último perfectamente estabilizado en condiciones de óptima accesibilidad.According to this structuring and how it follows from the observation of figure 2, the platform proper (6), and the operating surface will be provided with perforations (14) that finish off truncated conical protuberances, for Boost your grip, and is likely to get caught through the skirt (7) on a stair step (1), and simultaneously rest through the arms (11) on the step immediately lower, adopting a substantially horizontal position, projected outward, which allows both the layout on the same of a person as of any object, the latter being perfectly stabilized in optimal conditions accessibility.

Solo resta señalar por último que la plataforma propiamente dicha (2) incorpora en sus zonas laterales y próximas al faldón (7) sendas protuberancias exteriores (15), obtenidas mediante troquelado, que acoplándose ajustadamente entre los montantes de la armadura (1) de la escalera, estabilizan la plataforma frente a una posible tendencia al desplazamiento hacia dentro de la misma.It only remains to point out finally that the platform proper (2) incorporates in its lateral zones and next to the skirt (7) outer protuberances (15), obtained by die-cutting, which is tightly coupled between uprights of the frame (1) of the ladder, stabilize the platform facing a possible tendency to shift towards within it.
