OBJETO DE LA INVENCIÓN La presente invención se refiere a un nuevo dispositivo de seguridad para el uso de elementos que habitualmente se disponen suspendidos de un soporte superior desde el que cuelgan, posición desde la que se manipulan. OBJECT OF THE INVENTION The present invention relates to a new safety device for the use of elements that are usually arranged suspended from an upper support from which they hang, position from which they are handled.
Un ejemplo de elementos que se manipulan en suspensión, lo constituyen herramientas que se suspenden del soporte superior mediante un tubo de alimentación de la herramienta, en cuyo extremo inferior se soporta dicha herramienta, de manera que el tubo de alimentación puede ser elongado para desplazar la herramienta hasta la zona de trabajo por parte de un usuario. An example of elements that are manipulated in suspension, are tools that are suspended from the upper support by means of a tool feed tube, at which lower end said tool is supported, so that the feed tube can be elongated to move the tool up to the work area by a user.
Por lo general el tubo de alimentación presenta una configuración de tipo helicoidal que es adecuada para facilitar su elongación y desplazar la herramienta hasta la zona de trabajo. In general, the feeding tube has a helical type configuration that is suitable to facilitate its elongation and move the tool to the work area.
En otras aplicaciones se emplean cables extensibles con freno para soportar el elemento o herramienta. In other applications extendable cables with brake are used to support the element or tool.
El objeto de la invención es dotar al elemento en suspensión de un testigo de redundancia que indique cuando se produce una rotura del soporte superior del elemento suspendido. Para ello el testigo de redundancia del dispositivo de seguridad se activa cuando se produce la rotura del soporte superior de forma que se hace visible un tramo de cinta de un color llamativo que alerte de dicha rotura. De esta manera la cinta llama la atención al usuario indicándole que el soporte superior del elemento suspendido debe ser reparado para evitar posibles accidentes. ANTECEDENTES DE LA INVENCIÓN The object of the invention is to provide the suspended element with a redundancy token indicating when a breakage of the upper support of the suspended element occurs. For this, the redundancy warning light of the safety device is activated when the upper support is broken so that a section of tape of a striking color is visible that warns of said breakage. In this way the tape draws attention to the user indicating that the upper support of the suspended element must be repaired to avoid possible accidents. BACKGROUND OF THE INVENTION
En el estado de la técnica es conocido el empleo de elementos en suspensión, como por ejemplo pueden ser herramientas del tipo de las que se disponen suspendidas de un soporte superior, que comprende un doble soporte de seguridad constituido por un primer y un segundo soporte fijados unidos mediante eslabones, de modo que el tubo de alimentación está suspendido del primer soporte con lo que si se produce su rotura el conjunto queda suspendido del segundo soporte. Esta circunstancia se da por el hecho de que al requerirse la elongación del tubo de alimentación hasta la zona de trabajo, se obliga al primer soporte a soportar esfuerzos que con el uso continuado de la herramienta pueden dar lugar a su rotura, de forma que ello no impide que la herramienta pueda seguir siendo usada al quedar suspendida del segundo soporte, lo que en ocasiones puede determinar que el uso de la herramienta llegue a producir la rotura del segundo soporte con el consiguiente riesgo para los operarios. Dado que en la mayoría de los casos el soporte superior de la herramienta se encuentra dispuesto en el techo, los operarios no prestan atención al estado del mismo, por lo que puede producirse la caída de la herramienta sobre una persona que se encuentre debajo. The use of suspended elements is known in the state of the art, such as, for example, tools of the type that are suspended from an upper support, comprising a double safety support consisting of a first and second support fixed. linked by links, so that the feeding tube is suspended from the first support so that if it breaks, the assembly is suspended from the second support. This circumstance is due to the fact that when elongation of the feeding tube is required to the work area, forces the first support to withstand efforts that with the continued use of the tool can lead to its breakage, so that this does not prevent the tool from being able to continue being used when suspended from the second support, which can sometimes determine that the Using the tool will cause the second support to break with the consequent risk to the operators. Since in most cases the upper support of the tool is arranged on the roof, the operators do not pay attention to the state of the tool, so that the tool can fall on a person underneath.
En el estado de la técnica no existe ningún dispositivo que señalice cuando se produce una rotura de alguno de los elementos del soporte superior de la herramienta, de forma que dicho testigo llame la atención del operario indicándole que el soporte ha de ser reparado para evitar un posible accidente. In the state of the art there is no device that signals when there is a breakage of any of the elements of the upper support of the tool, so that this warning draws the attention of the operator indicating that the support has to be repaired to avoid a possible accident

Para ello la invención ha desarrollado un dispositivo de seguridad 4 que está constituido por una carcasa constituida por una pieza superior 5 y una pieza inferior 6 que están dotadas respectivamente de una ranura superior 7 y una ranura inferior 8, en cuyo interior alojan un carrete-contrapeso 9 que está constituido por un vástago 10 dotado de una ranura 1 1 y que está rematado en sus extremos por sendas porciones circulares 12. For this, the invention has developed a safety device 4 which is constituted by a housing consisting of an upper part 5 and a lower part 6 that are respectively provided with an upper groove 7 and a lower groove 8, inside which a reel houses Counterweight 9 which is constituted by a rod 10 provided with a slot 1 1 and which is finished at its ends by two circular portions 12.
En el ejemplo de realización la pieza superior 5 e inferior 6 de la carcasa presentan una configuración semicilíndrica que se unen entre sí alojando en su interior el carrete- contrapeso 9 de forma que sus porciones circulares 12 constituyen las bases laterales de la carcasa cuando se unen la pieza superior 5 y la pieza inferior 6. Esta unión se efectúa mediante un precinto rompible 16 que está constituido por una etiqueta adhesiva que envuelve a la carcasa de forma que dicha etiqueta adhesiva 16 está dotada de zonas carentes de material 18 dispuestas a lo largo de la zona de unión de la pieza superior 5 e inferior 6, de manera que establecen zonas de debilitamiento 17 para provocar su rotura cuando sufran una fuerza de tracción, tal y como será descrito con posterioridad. Dichas zonas carentes de material 18 y las zonas de habilitamiento 17 están calculadas para que dichas zonas de debilitamiento 18 se rompan a partir del momento en que tengan que soportar una fuerza de 1 N. Las piezas superior e inferior comprenden una zona abierta 19 dispuesta en correspondencia con las zonas carentes de material 18 del precinto 16, de manera que se permite la visualización de la cinta inferior en el interior de la carcasa. In the exemplary embodiment, the upper part 5 and lower part 6 of the housing have a semi-cylindrical configuration that is joined together housing the reel inside it. counterweight 9 so that its circular portions 12 constitute the lateral bases of the housing when the upper part 5 and the lower part 6 are joined. This connection is made by a breakable seal 16 which is constituted by an adhesive label that wraps the housing so that said adhesive label 16 is provided with areas devoid of material 18 arranged along the joining area of the upper part 5 and lower 6, so as to establish areas of weakening 17 to cause their breakage when they suffer a force of traction, as will be described later. Said areas devoid of material 18 and the enabling zones 17 are calculated so that said weakening zones 18 are broken from the moment they have to withstand a force of 1 N. The upper and lower parts comprise an open zone 19 arranged in correspondence with the material-free areas 18 of the seal 16, so that the display of the lower tape inside the housing is allowed.
La ranura 1 1 del vástago 10 del carrete-contrapeso 9 está prevista para introducir el extremo de una cinta inferior 14 que se enrolla sobre el carrete-contrapeso 9 de forma que el otro extremo de la cinta inferior 14 sale al exterior de la carcasa a través de la ranura inferior 8 de la pieza inferior 6, fijándose este extremo en una porción intermedia del soporte superior 3, y más concretamente en uno de los eslabones 3b que une el primer soporte 3a con el segundo soporte 3c. The groove 1 1 of the rod 10 of the spool-counterweight 9 is provided to introduce the end of a lower belt 14 that is wound on the spool-counterweight 9 so that the other end of the lower belt 14 comes out of the housing to through the lower groove 8 of the lower part 6, this end being fixed in an intermediate portion of the upper support 3, and more specifically in one of the links 3b that joins the first support 3a with the second support 3c.
Además el dispositivo de la invención cuenta con una cinta superior 13 que se retiene mediante la ranura superior 7 del cuerpo superior 5, de forma que su extremos superior se fija sobre la parte superior del soporte superior 3a y más concretamente sobre el primer soporte 3a. Furthermore, the device of the invention has an upper belt 13 that is retained by the upper groove 7 of the upper body 5, so that its upper ends are fixed on the upper part of the upper support 3a and more specifically on the first support 3a.
En base a la configuración descrita, se comprende fácilmente que cuando se produzca la rotura del primer soporte 3a se produce un descuelgue de la herramienta 1 , lo que hace que la cinta superior 13 se tense, tensión que igualmente se transmite a la cinta inferior 14, de forma que ambas fraccionan de las correspondientes piezas superior e inferior, con lo que la etiqueta adhesiva 16 se ve sometida a esta tracción, lo que produce la rotura de las zonas de debilitamiento 17 separándose la pieza superior 5 de la pieza inferior 16, con lo que el carrete-contrapeso 9 cae produciéndose el desenrollado de la totalidad de la cinta inferior 14, quedando el carrete-contrapeso colgando de su extremo, alertando de la rotura del soporte superior de la herramienta, ya que dicha cinta inferior constituye el despliegue de un testigo que indica dicha rotura. Based on the described configuration, it is easily understood that when the first support 3a breaks, a tool 1 is lifted, which causes the upper belt 13 to be tensioned, tension that is also transmitted to the lower belt 14 , so that both split of the corresponding upper and lower pieces, whereby the adhesive label 16 is subjected to this traction, which causes the breakage of the weakening zones 17 to separate the upper part 5 from the lower part 16, whereby the spool-counterweight 9 falls causing the unwinding of the entire lower belt 14, the spool-counterweight hanging from its end, warning of the breakage of the upper support of the tool, since said lower belt constitutes the deployment of a witness indicating said breakage.
Cabe señalar que la cinta inferior 14 es de un color llamativo que alerta al operario de la rotura del soporte, sin necesidad de que éste tenga que estar mirando al techo para verificar su estado, de modo que indique al operario que se debe reparar el soporte para evitar un posible accidente. It should be noted that the lower belt 14 is a striking color that alerts the operator to the breakage of the support, without the need for it to be facing the ceiling to verify its status, so that it indicates to the operator that the support must be repaired to avoid a possible accident.
Tanto la ranura superior 7 de la pieza superior 5, como la inferior 8 de la pieza inferior 6, como la ranura 11 del vástago 10 del carrete-contrapeso 9, están dotadas de elementos de freno de la cinta. Estos elementos de freno definen un trazado sinuoso determinado por resaltes 15 previstos en ambas caras de las ranuras 7, 8 y 1 1 , que colaboran para realizar la función de freno de las cintas 13 y 14 cuando el dispositivo está en reposo. Both the upper groove 7 of the upper part 5, and the lower groove 8 of the lower part 6, as well as the groove 11 of the rod 10 of the spool-counterweight 9, are provided with belt brake elements. These brake elements define a winding path determined by projections 15 provided on both sides of the grooves 7, 8 and 1 1, which collaborate to perform the brake function of the belts 13 and 14 when the device is at rest.
