DESCRIPCIÓN  DESCRIPTION

Dispositivo de protección aplicable a los postes de los guardarrayes de carreteras. Objeto de la invención Protection device applicable to road guard posts. Object of the invention

Las barreras de seguridad que escoltan los laterales de la vía, en aquellas zonas en las que existe peligro de que un vehículo abandone lateralmente la calzada, están constituidas por una banda metálica convenientemente curvada con cierta ondulación en forma de bionda, de forma que ofrecen un frente hacia la carretera carente de aristas. Esta banda se sitúa paralela a la calzada, soportada por postes verticales anclados en el suelo, que en la parte superior presentan un coliso u otro medio de fijación entre poste y barrera. The safety barriers that escort the sides of the road, in those areas where there is a danger of a vehicle leaving the road sideways, are constituted by a metal band conveniently curved with some bionda-shaped undulation, so that they offer a facing the road without edges. This band is located parallel to the roadway, supported by vertical posts anchored in the ground, which at the top have a collision or other means of fixing between post and barrier.

Estas barreras de seguridad funcionan adecuadamente con los coches y otros vehículos de cuatro o más ruedas ya que impiden que el vehículo se salga de la calzada y facilitan su retorno a la misma; no obstante, cuando se cae un motociclista, normalmente resbala por la vía y va a parar contra la barrera o contra los postes que la sustentan; éstos son vigas en "C" o en "H" que presentar aristas vivas lo que motiva, que además del golpe, el accidentado sufra frecuentemente amputaciones de algún miembro. These safety barriers work properly with cars and other vehicles with four or more wheels as they prevent the vehicle from leaving the road and facilitate its return to it; however, when a motorcyclist falls, he usually slides down the road and goes against the barrier or the posts that support it; these are beams in "C" or "H" that present live edges which motivates, that in addition to the blow, the injured person frequently suffers amputations of some member.

Así pues, el objeto de la presente invención es un dispositivo destinado a proteger los postes que soportan los guardarrayes que constituyen la barrera habitual de una carretera o autovía, que en caso de accidentes de tráfico de vehículos de dos ruedas provocan funestas consecuencias al impactar los conductores contra ellos. Thus, the object of the present invention is a device intended to protect the posts that support the guardrails that constitute the usual barrier of a road or highway, which in case of traffic accidents of two-wheelers cause serious consequences when impacting the drivers against them.

Antecedentes de la invención Background of the invention

Para evitar el impacto contra los postes que soportan la barrera de seguridad, se han diseñado multitud de elementos de revestimiento, que protegen los postes evitando así el impacto de la persona accidentada contra estos elementos metálicos. En la literatura de patentes podemos encontrar varias referencias a dispositivos de estas características. To avoid the impact against the posts that support the safety barrier, a multitude of cladding elements have been designed, which protect the posts thus avoiding the impact of the injured person against these metallic elements. In the patent literature we can find several references to devices of these characteristics.

i En su mayoría se trata de elementos de revestimiento rígidos o semi-rígidos; en otros casos están realizados en materiales flexibles, o presentan una configuración que permite absorber en cierta medida el impacto del cuerpo de la persona accidentada contra dicho poste. Un ejemplo de esta naturaleza se describe en el documento ES-2253993 en el que el revestimiento del poste está formado por varios aros cilindricos concéntricos de espesor variable, abiertos en un lado y realizados en material flexible deformable, con recuperación inmediata. Los problemas que plantean este tipo de soluciones, además de que es imprescindible que el material o la constitución del revestimiento sea capaz de absorber el impacto, radican en la forma de fijación al poste, ya que su colocación se ha de poder realizar de forma mecánica tanto en barreras de nueva construcción, como en barreras existentes. i They are mostly rigid or semi-rigid lining elements; in other cases they are made of flexible materials, or have a configuration that allows to absorb to some extent the impact of the body of the injured person against said post. An example of this nature is described in document ES-2253993 in which the lining of the post is formed by several concentric cylindrical rings of variable thickness, open on one side and made of deformable flexible material, with immediate recovery. The problems posed by this type of solutions, in addition to the fact that it is essential that the material or the constitution of the coating be able to absorb the impact, lie in the form of fixing to the post, since its placement must be able to be performed mechanically both in new construction barriers and in existing barriers.

El documento EP 1256659 describe un cilindro de absorción de impacto, hueco, que rodea el poste de apoyo de la bionda a lo largo de una carretera, que consta un cilindro rígido, interior capaz de girar alrededor del poste y un cilindro exterior de un diámetro más grande, hecho de un material blando, que tiene por finalidad resistir un impacto de un vehículo, o cuerpo de una persona proyectada contra dicho carril, para aliviar el daño posible. EP 1256659 describes a hollow impact absorption cylinder, which surrounds the bionda support post along a road, consisting of a rigid, inner cylinder capable of rotating around the pole and an outer cylinder of a diameter larger, made of a soft material, which aims to resist an impact of a vehicle, or body of a person projected against said lane, to alleviate the possible damage.

El documento WO2005075745 divulga un dispositivo de protección que presenta un revestimiento flexible susceptible de cubrir el poste, formado por un cuerpo de plástico con un desarrollo cilindrico y una sección transversal abierta que proporciona una abertura frontal longitudinal, de modo que se puede montar para abrazar un poste de apoyo de una barrera carretera. En una realización preferida, la protección está formada esencialmente por dos paredes cilindricas conectadas por nervios circulares que forman una envolvente que presenta un buen comportamiento a la absorción de golpes. WO2005075745 discloses a protection device that has a flexible coating capable of covering the post, formed by a plastic body with a cylindrical development and an open cross-section that provides a longitudinal front opening, so that it can be mounted to embrace a Support post of a road barrier. In a preferred embodiment, the protection is essentially formed by two cylindrical walls connected by circular ribs that form an envelope that exhibits a good shock absorption behavior.

El dispositivo descrito en el documento WO2012004445, del mismo inventor, prevé una protección de los postes que gira cuando se produce un impacto contra él. Este dispositivo resuelve favorablemente esta situación; no obstante deja sin cubrir situaciones en las que el accidentado impacta contra una zona intermedia, así como los posibles daños que se pueda causar cuando impacta frontalmente contra este dispositivo y no se produce el efecto de giro de la protección. Descripción de la invención The device described in WO2012004445, of the same inventor, provides for a protection of the posts that rotates when an impact occurs against it. This device resolves this situation favorably; however, it leaves uncovered situations in which the injured person hits an intermediate zone, as well as the possible damages that may be caused when it hits this device frontally and the protection's turning effect does not occur. Description of the invention

Estudios sobre seguridad vial, en concreto sobre los efectos del impacto de personar que se caen, normalmente de un vehículo de dos ruedas, he impactan contra el guardarraíl han venido a determinar que la principal causa de muerte y accidente grave se produce cuando el accidentado impacta contra el poste que sustenta la bionda o barrera que bordea la carretera. Para evitar que este impacto cause daños irreparables en el accidentado se han previsto tres aspectos: Studies on road safety, specifically on the effects of the impact of falling, usually from a two-wheeled vehicle, have impacted the guardrail have come to determine that the main cause of death and serious accident occurs when the injured person impacts against the pole that supports the bionda or barrier that borders the road. To avoid this impact causing irreparable damage to the injured, three aspects have been foreseen:

- Se ha previsto emplear un elemento de revestimiento para estos postes que sea blando y deformable, que absorban la energía del impacto en particular cuando la dirección de desplazamiento del accidentado sea perpendicular al poste. - It is planned to use a lining element for these posts that is soft and deformable, which absorb the energy of the impact in particular when the direction of travel of the injured person is perpendicular to the post.

- También se ha previsto que dicho elemento de revestimiento pueda girar en torno al poste, únicamente en caso de impacto, de forma que cuando el accidentado impacte lateralmente se produzca el desplazamiento del obstáculo, de forma que al moverse éste con el accidentado se reduce el impacto en gran medida. - It has also been foreseen that said cladding element can rotate around the post, only in the event of an impact, so that when the injured person impacts laterally, the movement of the obstacle occurs, so that when the latter moves with the injured person, the impact greatly.

Finalmente en aquellas circunstancias en las que el accidentado se desplaza por un punto intermedio entre dos postes y por tanto puede caerse a la cuneta o por el terraplén situado fuera de la carretera, se ha previsto que la longitud de estos revestimientos sea tal que entre dos postes consecutivos únicamente quede un espacio del orden de unos 30-40 cm. por el que difícilmente se puede colar una persona. El accidente en estos puntos prácticamente queda eliminado por la capacidad de ceder al girar ambos revestimientos como si se deformase la protección cuando se produce el impacto en esta zona intermedia. Finally, in those circumstances in which the injured person moves through an intermediate point between two posts and therefore can fall to the gutter or by the embankment located off the road, it is provided that the length of these linings is such that between two Consecutive posts only a space of the order of about 30-40 cm remains. through which you can hardly strain a person. The accident at these points is practically eliminated by the ability to yield by turning both coatings as if the protection deforms when the impact occurs in this intermediate zone.

Así pues, el dispositivo de protección contra impactos de personas en los postes de los guardarrayes de carreteras, objeto de la presente invención, resuelve de forma favorable todas las situaciones de accidente posibles, en particular reduciendo el efecto de choque contra el poste del guardarraíl; a este efecto, este dispositivo comprende: Una estructura soporte interior, preferentemente de naturaleza metálica o de un plástico o caucho resistente, la cual, en sección, define un hueco central, que tiene una sección ligeramente mayor que la del poste que soporta la bionda y una configuración similar al mismo. La forma de este hueco determina que el dispositivo pueda insertarse en el poste de arriba abajo en una barrera de nueva construcción o en la cual se ha desmontado el guardarraíl y también que tienda a mantenerse en posición paralela a la bionda. Al mismo tiempo, también ha de permitir que ante un impacto lateral efectúe un ligero giro, hasta un ángulo máximo del orden de 45e; a este efecto dicho hueco presenta una holgura o capacidad de deformación suficiente como para permitir el giro de la estructura sobre el soporte en determinadas condiciones. Thus, the protection device against impacts of persons on the posts of the road guard, object of the present invention, resolves favorably all possible accident situations, in particular by reducing the impact of collision against the guardrail post; For this purpose, this device comprises: An internal support structure, preferably of a metallic nature or of a resistant plastic or rubber, which, in section, defines a central hollow, which has a section slightly larger than that of the post that supports the bionde and a configuration similar to it. The shape of this hole determines that the device can be inserted into the post from top to bottom in a newly constructed barrier or in which the guardrail has been disassembled and also that it tends to remain in a position parallel to the bionda. At the same time, it must also allow a slight turn before a lateral impact, up to a maximum angle of the order of 45 e ; For this purpose, said gap has a clearance or deformation capacity sufficient to allow the structure to rotate on the support under certain conditions.

Sobre esta estructura el dispositivo monta un revestimiento flexible formado por dos o más ruedas recicladas de automóvil, de las cuales la zona central se ha cortado y retirado, mientras que la parte restante se ha deformado, aplastándolas lateralmente en sentido transversal para conformar una envolvente ovalada en torno a la estructura soporte interior, en la que el eje mayor se sitúa paralelo a la bionda o la carretera. La configuración de este revestimiento facilita el giro del dispositivo en cualquier condición, a menos que el impacto sea exactamente perpendicular a la bionda y hacia el centro del poste. On this structure the device mounts a flexible covering formed by two or more recycled automobile wheels, of which the central area has been cut and removed, while the remaining part has been deformed, crushing them laterally in a transverse direction to form an oval envelope around the inner support structure, in which the major axis is located parallel to the bionda or the road. The configuration of this coating facilitates the rotation of the device in any condition, unless the impact is exactly perpendicular to the bionde and towards the center of the post.

Exteriormente este dispositivo se estructura por medio de una banda flexible y resistente, también de configuración ovalada, que se coloca en torno a la estructura interior, dispuesta a recibir en su interior las ruedas de automóvil, para proporcionarles dicha forma ovalada. Externally this device is structured by means of a flexible and resistant band, also of oval configuration, which is placed around the interior structure, arranged to receive inside the automobile wheels, to provide said oval shape.

Finalmente, se prevé un relleno blando y/o con capacidad de deformación elástica ante un impacto, que ocupa el espacio y los huecos existentes entre la banda flexible y la estructura soporte interior. Finally, a soft padding and / or elastic deformation capacity is anticipated in the event of an impact, which occupies the space and the gaps between the flexible band and the inner support structure.

Opcionalmente, sobre la banda exterior se adhiere o fija durante la fabricación una lámina o placa, así mismo blanda y/o deformable, que presenta grabada o serigrafiada por su cara exterior un ángulo de bisectriz horizontal, que indicará la dirección de la carretera. El hueco interior de la estructura soporte presenta una configuración sensiblemente rectangular, cuyos lados transversales con respecto a la bionda son ligeramente más largos que los del poste y presentan sendas cara semicirculares, las cuales están definidas por sendos cilindros laterales huecos. Esta configuración tienden a mantener el dispositivo paralelo a la bionda, no obstante, en caso de impacto contra él, presenta la posibilidad de que el soporte gire sobre el poste y por tanto el dispositivo en su conjunto, de forma tal que cualquier impacto sobre él también supondrá un cierto giro del mismo, lo que evita que el impacto sea directo contra el poste, a menos que sea perpendicular a él. Optionally, a sheet or plate, also soft and / or deformable, adheres or screenprinted on its outer face an horizontal bisector angle, which will indicate the direction of the road, is adhered or fixed during manufacturing. The inner hollow of the support structure has a substantially rectangular configuration, whose transverse sides with respect to the bionda are slightly longer than those of the post and have semi-circular face paths, which are defined by two hollow side cylinders. This configuration tends to keep the device parallel to the bionda, however, in case of impact against it, it presents the possibility that the support rotates on the pole and therefore the device as a whole, so that any impact on it it will also involve a certain turn of the same, which prevents the impact from being direct against the post, unless it is perpendicular to it.

Se han previsto realizaciones alternativas para la fabricación y/o montaje de este dispositivo. Opcionalmente, la banda envolvente exterior puede sustituirse por unas cuerdas, cables, o elementos similares que le den forma a las ruedas de automóvil antes de ser introducidas sobre la estructura y durante el moldeo y el secado del relleno interior y exterior, para que mantengan su forma durante este proceso. En otra solución constructiva, la banda se puede sustituir por un revestimiento antiadherente que impregna el molde en el que se introducen las ruedas y la estructura interior antes del moldeo y el secado del relleno, de forma que es éste el que amalgama y mantiene la forma del dispositivo una vez se seca. Alternative embodiments are planned for the manufacture and / or assembly of this device. Optionally, the outer wrapping band can be replaced by ropes, cables, or similar elements that shape the car's wheels before being introduced on the structure and during the molding and drying of the inner and outer fill, so that they maintain their form during this process. In another constructive solution, the band can be replaced by a non-stick coating that impregnates the mold into which the wheels and the interior structure are introduced before molding and drying the filling, so that it is this that amalgams and maintains the shape of the device once it dries.

En otra solución alternativa, las ruedas se pueden sustituir por caucho picado o en trozos, proveniente de ruedas recicladas de vehículos. En ambos casos el primer recubrimiento después de la estructura interior rígida es flexible y por tanto permite reducir el impacto de una persona u objeto sobre él; mientras que el revestimiento más externo es deformable al impacto, o blando, a fin de que absorba la fuerza del impacto sobre él y en conjunto evitar el daño en el accidentado. In another alternative solution, the wheels can be replaced by chopped rubber or in pieces, from recycled vehicle wheels. In both cases, the first coating after the rigid interior structure is flexible and therefore allows the impact of a person or object on it to be reduced; while the outermost lining is deformable to impact, or soft, so that it absorbs the force of the impact on it and together prevents damage to the accident.

En otra solución alternativa la estructura soporte está abierta por la zona central, justamente en la parte que corresponde con el poste soporte de la bionda. De igual forma y enfrente a esa abertura se prevé que los elementos que conforman el revestimiento del dispositivo estén abiertos definiendo una ventana vertical en toda la altura del dispositivo. Al colocar esta ventana hacia la parte posterior, o sea la opuesta a la carretera, es posible introducir el dispositivo en un poste ya instalado, lo que permite la colocación de estas protecciones en carreteras con barreras instaladas. Con la finalidad de evitar también que en condiciones normales una persona pueda traspasar la barrera que conforman estos dispositivos debajo de la bionda, se ha previsto que el grado de deformación de las ruedas de automóvil insertadas en su fabricación, conjuntamente con la configuración de la banda flexible exterior sea tal que su eje mayor tenga una longitud que deje entre dos dispositivos colocados en dos postes consecutivos un espacio comprendido entre 10 y 50 cm., es decir un espacio que no permita el paso de una persona o que, de producirse, frene su paso de forma considerable. In another alternative solution, the support structure is open in the central area, just in the part corresponding to the bionde support post. In the same way and in front of that opening it is expected that the elements that make up the lining of the device are open defining a vertical window in the entire height of the device. By placing this window towards the back, that is, the opposite of the road, it is possible to insert the device into an already installed post, which allows the placement of these protections on roads with installed barriers. In order to also avoid that in normal conditions a person can cross the barrier that these devices make up under the bionda, it is provided that the degree of deformation of the car wheels inserted in its manufacture, together with the configuration of the band flexible exterior is such that its major axis has a length that leaves a space between 10 and 50 cm between two devices placed on two consecutive posts, that is, a space that does not allow the passage of a person or that, if produced, stops It happened considerably.

También se ha tenido en cuenta el posible impacto de un vehículo contra esta protección. Mientras que el choque contra una protección convencional suponía su rotura y en consecuencia la formación de aristas vivas que implicaban un problema añadido a los accidentes de ciclistas o motociclistas, en la protección presente es difícil que el impacto de un automóvil suponga su rotura, porque gira y se acomoda a la parte que incide sobre ellas; es más, esta protección reduce también en parte el choque de un vehículo contra el guardarraíl. The possible impact of a vehicle against this protection has also been taken into account. While the crash against a conventional protection meant its breakage and consequently the formation of living edges that implied an added problem to the accidents of cyclists or motorcyclists, in the present protection it is difficult for the impact of a car to suppose its breakage, because it rotates and it adapts to the part that affects them; Moreover, this protection also partially reduces the collision of a vehicle against the guardrail.

Estamos pues ante un dispositivo realizado con materiales reciclados, que no sólo presenta un cuerpo flexible y deformable al impacto, sino que además gira cuando se impacta contra él, de forma que el golpe se minimiza de forma considerable en comparación con otros dispositivos existentes. We are therefore faced with a device made of recycled materials, which not only has a flexible and deformable impact body, but also rotates when it is struck against it, so that the blow is minimized considerably compared to other existing devices.

Como se puede observar en las figuras referenciadas, se trata de un dispositivo para proteger los postes (2) que soportan las biondas o barreras guardarraíl (1 ) que se colocan en determinados puntos de una calzada para evitar que los vehículos se salgan de la vía en caso de accidente, pero que en sí, constituyen un problema añadido cuando el accidentado es un ciclista o motorista que impacta contra dichos postes. As can be seen in the referenced figures, it is a device to protect the posts (2) that support the biondas or guardrail barriers (1) that are placed at certain points of a roadway to prevent vehicles from getting out of the way In the event of an accident, but that in itself, they constitute an added problem when the injured person is a cyclist or motorcyclist who impacts against these posts.

La base de este dispositivo radica en la reutilización de ruedas usadas de automóvil estándar, con lo cual no solo se resuelve el problema de la protección de los postes, sino también el de dar salida a este tipo de productos reciclados, cuya reutilización y reubicación resulta habitualmente difícil y costosa. The basis of this device lies in the reuse of used standard car wheels, which not only solves the problem of the protection of the posts, but also of giving way to this type of recycled products, whose reuse and relocation results usually difficult and expensive.

El dispositivo comprende un alma (3) que define un hueco interior (31 ) acorde al poste (2), de forma que éste puede deslizarse por dentro para introducir el dispositivo de arriba abajo cuando la bionda (1 ) está en proceso de instalación o desmontada. Se ha previsto que la longitud de este hueco sea ligeramente mayor que la del poste (2) y que los laterales mayores sean redondeados, a efectos de que el poste (2) ante una fuerza lateral, como la que se produciría en caso de impacto sobre el dispositivo, pueda girar un ángulo aproximado de 45e. En definitiva, esta estructura interior (1 ) está formada por dos tubos (32) soldados con cierta separación mediante dos chapas paralelas que definen el hueco interior (31 ). The device comprises a core (3) that defines an inner hole (31) according to the post (2), so that it can slide inside to introduce the device from top to bottom when the bionda (1) is in the process of installation or disassembled It is envisaged that the length of this gap is slightly greater than that of the post (2) and that the larger sides be rounded, so that the post (2) faces a lateral force, such as that which would occur in case of impact on the device, you can rotate an angle of approximately 45 e . In short, this interior structure (1) is formed by two welded tubes (32) with a certain separation by means of two parallel plates that define the internal hollow (31).

Revistiendo dicha estructura interior (3) se colocan dos ruedas usadas de automóvil (4) apiladas, lo que hace una altura comprendida entre 40 y 45 cm., o sea un poco menos que la altura habitual a la que se coloca el guardarraíl (1 ). A estas ruedas (4) se les ha eliminado una banda entorno al hueco interior a fin de que resulten fácilmente deformables y sean más flexibles. Por fuera y con la finalidad de proporcionales una forma ovalada a las ruedas (4) se coloca una banda flexible (5) y todo ello se introduce en un molde en el que se rellenan los huecos con un polímero (7), que en combinación con el caucho de las ruedas (4) es capaz de absorber impactos de alta energía. Coating said interior structure (3) two stacked used car wheels (4) are placed, which makes a height between 40 and 45 cm., That is a little less than the usual height at which the guardrail is placed (1 ). To these wheels (4) a band around the inner hollow has been removed so that they are easily deformable and more flexible. Outside and for the purpose of proportionally an oval shape to the wheels (4) a flexible band (5) is placed and all this is introduced into a mold in which the holes are filled with a polymer (7), which in combination with the rubber of the wheels ( 4) It is capable of absorbing high energy impacts.

Por la cara exterior, la que queda enfrentada a la calzada, se coloca un lámina (6) en la que se ha grabado o serigrafiado un ángulo (61 ) que se colocará en la dirección de la carretera. De hecho no es necesario fabricar dos modelos diferentes para izquierda y derecha, puesto que el dispositivo es reversible. Esta lámina (6) también puede ser una placa de un polímero similar o igual al del relleno interior, en cuyo caso se colocará sobre la banda flexible (5) antes de la aplicación del mismo para que quede embebida en él. On the outer face, which faces the roadway, a sheet (6) is placed on which an angle (61) has been engraved or screen printed to be placed in the direction of the road. In fact it is not necessary to manufacture two different models for left and right, since the device is reversible. This sheet (6) can also be a plate of a polymer similar or equal to that of the inner padding, in which case it will be placed on the flexible strip (5) before applying it so that it is embedded in it.

Es posible prescindir de la banda flexible (5) en la fabricación de este dispositivo. En este caso será necesario disponer unas simples cuerdas u otro medio que mantenga la forma ovalada en las ruedas (4) mientras éstas se introducen en el molde y se endurece el polímero (7), que sería en este caso el que proporcionaría la forma al dispositivo. It is possible to dispense with the flexible band (5) in the manufacture of this device. In this case it will be necessary to arrange simple ropes or other means that maintain the oval shape on the wheels (4) while they are introduced into the mold and the polymer (7) hardens, which would be in this case the one that would provide the shape to the device.

El cualquier caso el dispositivo presenta una envolvente al poste (2) de sección ovalada que presenta una longitud comprendida entre 70 y 90 cm. de forma tal que, en una instalación estándar de una bionda (1 ) en la que la separación entre postes está comprendida entre 100 y 120 cm., el hueco que queda entre dos dispositivos consecutivos estará comprendido entre 10 y 50 cm., de forma tal que si el accidentado impacta justamente en el hueco, queda frenado sin conseguir pasar al otro lado de la bionda, fuera de la carretera. In any case, the device has an envelope to the oval section post (2) having a length between 70 and 90 cm. so that, in a standard installation of a bionde (1) in which the spacing between posts is between 100 and 120 cm., the gap between two consecutive devices will be between 10 and 50 cm., so such that if the injured person impacts just in the hollow, it is stopped without being able to pass to the other side of the bionda, off the road.
