Description
DESCRIPCIÓN DISPOSITIVO DE PROTECCIÓN . DESCRIPTION PROTECTION DEVICE.
Objeto de la invención. Object of the invention.
La presente invención se refiere a un dispositivo de protección ; del tipo de los destinados a montarse sobre dos postes o puntales para delimitar espacios evitando el paso o la caída de personas. The present invention relates to a protection device; of the type of those destined to mount on two posts or props to delimit spaces avoiding the passage or the fall of people.
Antecedentes de la invención. Background of the invention.
En las obras de construcción es habitual delimitar zonas de paso o de trabajo con el fin de evitar la caída de personas al vacío, utilizando barandillas o protecciones de diferentes tipos. Concretamente en los edificios en construcción se disponen en el contorno de los forjados unos postes sobre los que se fijan los medios de protección, compuestos simplemente por unas tablas de madera. En algunos casos los postes disponen de unos ganchos o pasajes transversales para el apoyo del extremo de las tablas de cierre. Cuando los postes no disponen de pasajes o ganchos específicos, como ocurre con los puntales de soporte del encofrado, las tablas se fijan a dichos puntales con alambre. In construction works it is usual to delimit areas of passage or work in order to prevent people from falling into a vacuum, using railings or protections of different types. Specifically in the buildings under construction, posts are placed on the contour of the slabs on which the protection means are fixed, consisting simply of wooden boards. In some cases the posts have hooks or transverse passages for the support of the end of the closing tables. When the posts do not have specific passages or hooks, as with the formwork support struts, the boards are fixed to said struts with wire.
En ambos casos las tablas actúan más como barrera visual que como elemento de protección, ya que es habitual que no se encuentren sólidamente fijadas a los postes o puntales. In both cases the tables act more as a visual barrier than as a protective element, since it is usual that they are not solidly fixed to the posts or struts.
La conformación de estas barreras con tablas es especialmente lenta y pesada, ya que requiere el transporte de las tablas hasta la zona de colocación y la utilización de un tiempo importante para su colocación si se desea que queden bien fijadas. The conformation of these barriers with boards is especially slow and heavy, since it requires the transportation of the boards to the placement area and the use of an important time for their placement if they are to be well fixed.
Otro de los inconvenientes de este tipo de barandillas es que las tablas se rajan y deterioran durante su colocación, desmontaje y transporte, quedando con frecuencia inservibles para una posterior utilización.
Descripción de la invención Another of the disadvantages of this type of railings is that the boards are cracked and deteriorated during their placement, disassembly and transport, being often unusable for later use. Description of the invention
Para solventar los problemas se ha ideado el dispositivo de protección objeto de la invención que, siendo de una gran sencillez constructiva y de un bajo coste de fabricación, presenta unas particularidades orientadas a: facilitar su manipulación, transporte y colocación, permitir su reutilización, conformar una barrera efectiva y que no produce cortes o contusiones en caso de que las personas choquen o caigan contra el mismo, y permitir la aplicación sobre el mismo de motivos diversos, actuando simultáneamente como elemento de protección y como soporte publicitario o informativo. To solve the problems, the protection device object of the invention has been devised that, being of great constructive simplicity and of a low manufacturing cost, has particularities oriented to: facilitate its handling, transport and placement, allow its reuse, shape an effective barrier that does not produce cuts or bruises in the event that people collide or fall against it, and allow the application on it of various reasons, acting simultaneously as an element of protection and as an advertising or informational support.
De acuerdo con la invención, este dispositivo de protección, comprende un elemento laminar, flexible y resistente, de configuración general rectangular, que presenta unos tramos extremos alineados longitudinalmente y de diferentes anchuras. In accordance with the invention, this protection device comprises a flexible and resistant laminar element of general rectangular configuration, which has longitudinally aligned end sections of different widths.
El tramo extremo de mayor anchura comprende en la proximidad de los bordes superior e inferior unos ganchos para su fijación a un primer poste, puntal o similar, mientras que el tramo extremo de menor anchura comprende unos ganchos destinados a introducirse de forma selectiva en respectivos ojales de sendas alineaciones longitudinales de ojales definidos en la superficie posterior del elemento laminar, de forma que dicha porción extrema de menor anchura conforma un bucle de longitud regulable para la recepción en su interior de un segundo poste o puntal y el tensado de elemento laminar. The end section of greater width comprises in the proximity of the upper and lower edges hooks for fixing to a first post, strut or similar, while the end section of smaller width comprises hooks intended to be introduced selectively into respective eyelets of longitudinal alignment of defined eyelets on the rear surface of the laminar element, so that said lower portion of smaller width forms a loop of adjustable length for the reception inside of a second post or strut and the tension of laminar element.
La diferencia de anchura de los tramos extremos del elemento laminar tiene la finalidad de permitir que los ganchos del tramo de mayor anchura queden separados en una distancia mayor que el ancho del tramo de menor anchura. De este modo es posible fijar sobre un mismo poste o puntal los extremos opuestos de dos dispositivos consecutivos, sin que interfieran entre sí y de forma que no queden huecos apreciables entre ellos. The difference in width of the end sections of the laminar element is intended to allow the hooks of the section of greater width to be separated by a distance greater than the width of the section of smaller width. In this way it is possible to fix the opposite ends of two consecutive devices on the same post or strut, without interfering with each other and so that there are no appreciable gaps between them.
Cabe mencionar que el elemento laminar puede estar conformado mediante un tejido, por ejemplo de rafia, una lona, o cualquier otro material similar, que sea ligero y que presente una elevada resistencia a los esfuerzos de tracción. It should be mentioned that the laminar element can be formed by a fabric, for example of raffia, a canvas, or any other similar material, which is light and has a high tensile strength.
El carácter flexible del elemento laminar permite su plegado, lo que facilita el transporte en comparación con las tablas u otros elementos rígidos de longitud
más o menos elevada. Otra de las ventajas que proporciona la utilización de un elemento laminar flexible es que evita el riesgo de lesiones en caso de que la persona u operario caiga contra el mismo. The flexible nature of the laminar element allows its folding, which facilitates transport compared to tables or other rigid elements in length more or less elevated. Another advantage provided by the use of a flexible laminar element is that it avoids the risk of injury in case the person or operator falls against it.
Este dispositivo permite una colocación rápida y sencilla sobre postes o puntales, ya que basta coger uno de los postes o puntales con los ganchos correspondientes al tramo extremo de mayor anchura, formar con el extremo de menor anchura un bucle que abrace el otro poste o puntal, tensar el elemento laminar y fijar los ganchos de este tramo extremo de menor anchura a los pasajes posteriores que se encuentren lo más alejado posible del segundo poste. This device allows a quick and simple placement on posts or struts, since it is enough to take one of the posts or struts with the hooks corresponding to the widest end section, form a loop that embraces the other post or strut with the smaller width end , tension the laminar element and fix the hooks of this lower section of smaller width to the rear passages that are as far away as possible from the second post.
De acuerdo con la invención, el elemento laminar presenta una superficie anterior apta para la aplicación de motivos diversos, por ejemplo mediante técnicas de impresión, lo que permite la utilización adicional del dispositivo como soporte publicitario o informativo. According to the invention, the laminar element has a front surface suitable for the application of various motifs, for example by printing techniques, which allows the additional use of the device as advertising or informational support.
Este dispositivo comprende al menos dos bandas de material flexible dispuestas sobre la cara posterior del elemento laminar y fijadas al mismo mediante unas costuras transversales interdistanciadas que definen entre sí las alineaciones de ojales para la inserción de los ganchos correspondientes al tramo extremo de menor anchura. This device comprises at least two bands of flexible material disposed on the rear face of the laminar element and fixed thereto by means of interdistanced transverse seams that define each other the eyelet alignments for the insertion of the hooks corresponding to the smaller end section.

Realización preferente de la invención. Preferred embodiment of the invention.
Como se puede observar en el ejemplo de realización mostrado en las figuras adjuntas el dispositivo de protección comprende un elemento laminar (1) flexible y resistente, en este caso de tejido de rafia, de configuración general rectangular, que presenta dos tramos extremos (11, 12), alineados longitudinalmente y de diferentes anchuras. As can be seen in the example of embodiment shown in the attached figures, the protection device comprises a flexible and resistant laminar element (1), in this case of raffia fabric, of general rectangular configuration, which has two end sections (11, 12), longitudinally aligned and of different widths.
El tramo extremo (12) de mayor anchura comprende en la proximidad de los bordes superior e inferior, unos ganchos (2) y el tramo extremo (11) de menor anchura también dispone en sus extremos de unos ganchos (3). The end section (12) of greater width comprises in the vicinity of the upper and lower edges, hooks (2) and the end section (11) of smaller width also has hooks (3) at its ends.
El elemento laminar dispone en su superficie posterior de unas bandas (4) de material flexible, alineadas con los ganchos (3) del tramo extremo (11) de menor anchura y cosidas al mencionado elemento laminar (1) mediante unas costuras (41) transversales, definiendo sendas alineaciones de ojales (5). The laminar element has on its rear surface bands (4) of flexible material, aligned with the hooks (3) of the end section (11) of smaller width and sewn to said laminar element (1) by transverse seams (41) , defining paths of eyelets (5).
El elemento laminar (1) presenta una superficie anterior portadora de motivos (6) impresos, con fines decorativos o informativos. The laminar element (1) has an anterior surface bearing printed motifs (6), for decorative or informative purposes.
Como se puede observar en las figuras 3, 4 y 5 para colocar el dispositivo sobre puntales o postes (7), convenientemente fijados, basta con sujetar el extremo de la porción (12) de mayor anchura, por medio de los ganchos (2) correspondientes sobre uno de los postes o puntales (7) y rodear el otro poste o puntal (7) con la porción extrema (11) de menor anchura, formando un bucle. Una vez tensado el elemento laminar (1) se introducen los ganchos (3) de la porción extrema (11) en los ojales (5) que se encuentren en la posición mas alejada posible del segundo poste, cerrando dicho bucle, con lo que queda garantizada la posición del elemento laminar. As can be seen in figures 3, 4 and 5 to place the device on struts or posts (7), conveniently fixed, it is enough to hold the end of the portion (12) of greater width, by means of the hooks (2) corresponding on one of the posts or struts (7) and surrounding the other post or strut (7) with the end portion (11) of smaller width, forming a loop. Once the laminar element (1) is tensioned, the hooks (3) of the end portion (11) are introduced into the eyelets (5) that are in the furthest position possible from the second post, closing said loop, thereby remaining guaranteed the position of the laminar element.
Como se puede observar en las figura 6, la anchura del tramo extremo (12) de mayor anchura, es mayor que la separación existente entre los ganchos (3) del tramo
extremo (11) y que la anchura del propio tramo extremo (11) de menor anchura, lo que permite el enganche de los extremos opuestos de dos dispositivos consecutivos sobre un mismo poste o puntal, sin que interfieran entre sí y definiendo una superficie de protección prácticamente continua, es decir, sin huecos intermedios de amplitud significativa. As can be seen in Figure 6, the width of the widest end section (12) is greater than the gap between the hooks (3) of the section end (11) and that the width of the end section itself (11) of smaller width, allowing the coupling of the opposite ends of two consecutive devices on the same post or strut, without interfering with each other and defining a protection surface practically continuous, that is, without intermediate gaps of significant amplitude.
