PLANCHONES, VOLCOS O VAGONES  PLANCHONES, VOLCOS OR WAGONS
DESCRIPCION DESCRIPTION
Sector Tecnológico Technology Sector
La presente invención describe un mecanismo retráctil de lonas para cubrir productos que son transportados en Planchones, Voleos o Vagones. The present invention describes a retractable canvas mechanism to cover products that are transported in Planchones, Volleos or Wagons.
Su aplicación es el cubrimiento de la carga en planchones, voleos o vagones de 5 a 15 metros de largo, de tal manera que el producto que se está trasportando quede totalmente cubierto. Its application is the covering of the load in slabs, volleys or wagons of 5 to 15 meters long, so that the product being transported is completely covered.
Su campo de acción se encuentra en el sector del trasporte, infraestructura, agroindustria, construcción y en general del transporte de productos y/o mercancías que necesiten ser cubiertas y protegidas. El mecanismo de la invención presenta una serie de elementos que permiten el desplazamiento por el planchón, volcó o vagón para realizar el cubrimiento de la mercancía que se va a transportar, así como el repliegue y liberación de la superficie para la tarea de cargue y descargue. Its field of action is in the sector of transport, infrastructure, agribusiness, construction and in general the transport of products and / or goods that need to be covered and protected. The mechanism of the invention presents a series of elements that allow the movement by the slab, dump or wagon to cover the merchandise to be transported, as well as the folding and releasing of the surface for the loading and unloading task. .
Estado de la Técnica State of the Art
En la actualidad los materiales trasportados, según la legislación vigente, deben ir cubiertos por una lona para evitar los posibles daños externos que se puedan ocasionar con la salida incontrolada de materiales, tal es el caso de los materiales sueltos (gravas, arenas y escombros etc.). La lona que es independiente del planchón, volco, o vagón debe ser extendida y fijada en cada viaje por el propio conductor, normalmente de forma manual, y muchas veces con la ayuda de terceros. Una vez realizado el trasporte debe ser recogida y retirada, labor difícil debido al esfuerzo físico requerido por parte de la persona o personas que realizan esta labor. Por otra parte se ha comprobado el riesgo laboral para conductores y terceros que realizan esta labor dando origen a frecuentes accidentes laborales. At present, the transported materials, according to current legislation, must be covered by a tarp to avoid possible external damages that may be caused by the uncontrolled exit of materials, such is the case of loose materials (gravels, sand and rubble etc. .). The canvas that is independent of the slab, dump, or wagon must be extended and fixed on each trip by the driver himself, usually manually, and often with the help of third parties. Once the transport has been carried out, it must be collected and withdrawn, difficult work due to the physical effort required by the person or persons performing this work. On the other hand, the occupational risk for drivers and third parties who carry out this work has been proven giving rise to frequent accidents at work.
Es conocido el sistema de plegado automático que extiende la lona de protección que va recogida en la parte delantera, en un eje, pero este sistema no ejerce ninguna seguridad respecto del material que trasporta, puesto que este puede desprenderse por toda la parte longitudinal del mismo, ya que solo ejerce fuerza en los puntos traseros y delanteros del conjunto. It is known the automatic folding system that extends the protective canvas that is collected in the front, on an axis, but this system does not exert any security with respect to the material that it transports, since this can be detached throughout the longitudinal part thereof , since it only exerts force on the rear and front points of the set.
El documento ES 2 207 404, plantea un sistema que se encuentra anclado al volcó, constituido por medio de una serie de travesaños y parejas diagonales articuladas en su punto medio que componen un mecanismo de tijeras múltiple, los cuales realizan el arrastre de la lona sin necesidad de cable guía o carriles adicionales. Document ES 2 207 404, proposes a system that is anchored to the volcano, constituted by means of a series of crossbars and diagonal couples articulated at its midpoint that make up a multiple scissors mechanism, which carry out the drag of the canvas without Need for guide wire or additional rails.
Asimismo el documento ES 1 073 539, presenta un sistema que va aferrado en la parte delantera del vehículo sobre un chasis de movimiento de un mástil extensible verticalmente mediante el accionamiento de un pistón neumático que comprende, al menos, el uso de una cadena y un eje de trasmisión. El mástil a su vez lleva unido a su extremo unas tijeras extensibles horizontales y unos tubos extensibles telescópicamente en su eje vertical. Also, document ES 1 073 539, presents a system that is clinging to the front of the vehicle on a chassis of movement of a vertically extendable mast by means of the actuation of a pneumatic piston comprising, at least, the use of a chain and a transmission shaft The mast in turn has attached horizontal extendable scissors and telescopically extendable tubes along its vertical axis.
Estas dos estructuras anteriormente mencionadas y documentadas, presentan frente a la invención propuesta una serie de inconvenientes al tener que implementar un sistema de bisagras que pueden desgastarse y fallar, además el sistema de tracción con rodamientos al no trabajar sobre una guía tiende a ser muy frágil. Por otro lado, el sistema de mástil extensible vertical es un elemento sin seguridad y firmeza para la sostenibilidad del peso de la estructura, y por estar expuesta a golpes por la acción de carga de los brazos del montacargas, corre el riesgo de dañarse constantemente incrementado los costos de mantenimiento por la cantidad de averías que se generan. These two structures previously mentioned and documented, have a series of drawbacks in the face of the proposed invention, since they have to implement a hinge system that can wear out and fail, and the traction system with bearings when not working on a guide tends to be very fragile. . On the other hand, the vertical extensible mast system is an element without security and firmness for the sustainability of the weight of the structure, and because it is exposed to shocks by the loading action of the forklift arms, it runs the risk of constantly increasing damage. maintenance costs for the amount of breakdowns that are generated.
El documento EP 1 529 671 da a conocer un sistema de accionamiento para una lona para recubrir contenedores de vehículos. Dicha lona es tensada mediante uno o más cables de bucle que se desplazan mediante poleas de accionamiento que les transfieren el movimiento necesario para desplazar la lona. EP 1 529 671 discloses a drive system for a tarp for coating vehicle containers. Said canvas is tensioned by means of one or more loop cables that are moved by means of drive pulleys that transfer the necessary movement to move the canvas.
En el documento ES 2 147 125 se observa un sistema de recogida y extendido de lonas para cubrición de cajas de vehículos mediante la disposición de una serie de arquillos transversales, en este caso el desplazamiento de los arquillos se realiza mediante unos cables guiados por poleas y accionados en su desplazamiento por un tambor de arrollamiento que puede ser accionado manualmente mediante manivela o de manera motorizada. Document ES 2 147 125 shows a system for collecting and extending tarpaulins to cover vehicle boxes by arranging a series of transverse arches, in this case the displacement of the arches is carried out by means of cables guided by pulleys and driven in its movement by a winding drum that can be operated manually by crank or motorized.

Due to the circumstances described above, the invention proposes a retractable mechanism for tarpaulins to cover slabs, volleys or wagons, which allows the driver to manually carve and unload from the floor without incurring any risk for handling heights; The invention provides a novel, simple and easy to execute mechanical system.
El mecanismo retráctil de lonas para cubrir planchones, voleos o vagones de la invención está diseñado para mejorar el rendimiento y obtener un máximo desempeño y rentabilidad en comparación a otros métodos tradicionales. Es un mecanismo versátil que permite abrir la lona desde la parte posterior o frontal del planchón, volco o vagón. El mecanismo retráctil de lonas para cubrir planchones, voleos o vagones de la invención cuenta con elementos conjugados que dan lugar a un resultado final en el que se aportan características significativas y novedosas frente al estado de la técnica. The retractable canvas mechanism to cover slabs, volleys or wagons of the invention is designed to improve performance and obtain maximum performance and profitability compared to other traditional methods. It is a versatile mechanism that allows you to open the canvas from the back or front of the slab, dump or wagon. The retractable canvas mechanism to cover slabs, volleys or wagons of the invention has conjugated elements that give rise to a final result in which significant and novel features are provided compared to the prior art.
El mecanismo retráctil de lonas para cubrir planchones, voleos o vagones de la invención, consiste en la disposición, sobre la parte superior del planchón, volco o vagón, de una serie de carros transversales donde se va a fijar o apoyar la lona que cubre la mercancía, pudiéndose desplazar estos carros por un riel dispuesto en los laterales del planchón, volco o vagón. The retractable canvas mechanism to cover slabs, volleys or wagons of the invention consists in the arrangement, on the top of the slab, dump or wagon, of a series of transverse carriages where the canvas covering the roof is to be fixed or supported. merchandise, being able to move these cars by a rail arranged on the sides of the slab, dump or wagon.
Esta serie de carros son de dos tipos: 2 carros de arrastre, uno delantero y uno trasero y carros intermedios (sencillos) distribuidos en forma equidistante que permiten el desplazamiento hacia adelante o hacia atrás de la lona por medio del riel. Tanto los carros de arrastre como los carros intermedios cuentan con medios de rodadura. En su pie se encuentra una base rectangular provista de ruedas de Nylon y rodamientos que se encajan o montan en rieles dispuestos a lo largo de las partes laterales del planchón, volcó ó vagón. This series of cars are of two types: 2 drag cars, one front and one rear and intermediate cars (simple) distributed in an equidistant way that allow the forward or backward movement of the canvas by means of the rail. Both drag cars and intermediate cars have rolling means. On its foot is a rectangular base provided with Nylon wheels and bearings that fit or mount on rails arranged along the side parts of the slab, tipped or wagon.
El riel está conformado por una canal en forma de "C", con aletas dobladas a 90° en la parte superior e inferior, el cual hace de guía para el movimiento de las ruedas en forma vertical. En la aleta inferior lleva una canal en forma de "U" inversacon unas aletas dobladas a 90° a su costados el cual, guía el rodamiento en forma horizontal para darle una mayor estabilidad y garantizar un buen movimiento en las fuerzas horizontales y verticales ejercidas por la persona que realiza el carpado y descarpado del planchón, volcó o vagón; estas piezas están formadas en material ASTM A 36 HR y van unidas para su funcionamiento. The rail consists of a "C" shaped channel, with fins folded at 90 ° at the top and bottom, which acts as a guide for the movement of the wheels vertically. In the lower fin it has a reverse "U" shaped channel with fins folded at 90 ° at its sides which guides the bearing horizontally to give it greater stability and ensure good movement in the horizontal and vertical forces exerted by the person who performs the carpating and shedding of the slab, overturned or wagon; These pieces are formed in ASTM A 36 HR material and are joined for operation.
Para el repliegue de la lona el mecanismo de la invención cuenta además con mecanismos tipo tijera, conformados por dos piezas diagonales y acoplados por sus extremos inferiores a los costados inferiores de los carros mediante tornillos los cuales permiten su oscilación, y en la parte superior va sujetaa la lona por medio de veleros. El mecanismo tipo tijera relaciona entre si los carros, y está dispuesto de tal manera que cada carro recibe una pareja de diagonales con el fin de unirlos de forma que cuando los carros se juntan por medio de un impulso provocado por una persona, la pareja de diagonales se cierra en su articulación y se juntan, esto hace que por ir en posición diagonal este lleve más longitud y la hace prolongar, lo que permite estirar y contraer la lona, de tal forma que al movimiento de los carros de arrastre delantero o trasero tiran o empujan los demás. A su vez, el mecanismo tipo tijera provoca que el repliegue de la lona se doble hacia el exterior del planchón, volco o vagón y no a su interior por causa de un fleje que contiene una memoria y que va instalado en los extremos inferiores a todo lo largo de la lona. For the folding of the canvas, the mechanism of the invention also has scissor-type mechanisms, formed by two diagonal pieces and coupled by their lower ends to the lower sides of the carriages by means of screws which allow their oscillation, and in the upper part it goes hold the canvas by sailboats The scissor-type mechanism relates the cars to each other, and is arranged in such a way that each car receives a pair of diagonals in order to join them so that when the cars come together by means of an impulse caused by a person, the couple of diagonals closes in their articulation and come together, this means that by going in a diagonal position it takes longer and makes it extend, which allows the canvas to stretch and contract, so that the movement of the front or rear drag cars throw or push others. In turn, the scissor mechanism causes the folding of the canvas to bend towards the outside of the slab, dump or wagon and not inside because of a strap that contains a memory and that is installed at the lower ends of everything along the canvas.
Se ha calculado que para realizar el cubrimiento total de un planchón, volco o vagón de 5 a 15 metros de longitud se necesitan dos carros de arrastre, delantero y trasero, y de varios carros intermedios, esta información no es limitativa. It has been calculated that to carry out the total coverage of a slab, dump or wagon of 5 to 15 meters in length, two drag cars, front and rear, and several intermediate cars are needed, this information is not limiting.
En el pie de los carros, arrastre e intermedios se encuentra una base rectangular, provista de ruedas de nylon y rodamientos, que conforman los medios de rodadura, y se desplazan dentro del riel. At the foot of the cars, drag and intermediate is a rectangular base, provided with nylon wheels and bearings, which make up the rolling means, and move inside the rail.
Con la instalación de estos elementos se consigue comunicar el movimiento de apertura y cierre a todos los carros, logrando que el conjunto pueda actuar por la acción única del carro de arrastre delantero o trasero, operación que es realizada por una persona en forma manual desde el piso. With the installation of these elements, the opening and closing movement can be communicated to all the cars, making it possible for the assembly to act by the single action of the front or rear drag car, an operation that is performed by a person manually from the floor.
La lona va sujeta a los carros de arrastre delantero y trasero por su periferia por medio de un conjunto de tornillos autoperforantes con arandela y entre la lona y los tornillos va una cinta o reata para evitar el rasgado de la lona. En su interior la lona va reforzada con tiras a lo ancho y llevan bolsillos los cuales la sujetan a los carros y a su mecanismo de tijeras por medio de velero. A su vez en el movimiento de los carros y el mecanismo de tijeras provocan que el repliegue de la lona se doble hacia su exterior del planchón, volco o vagón y en sus laterales no la deja introducir en su interior por causa de un fleje que contiene una memoria y que va instalado en los extremos inferiores a lo largo de la lona. The canvas is attached to the front and rear drag cars by its periphery by means of a set of self-drilling screws with washer and between the canvas and the screws there is a tape or reta to avoid tearing the canvas. Inside the canvas is reinforced with wide strips and carry pockets which hold it to the cars and its scissors mechanism by means of a sailboat. At the same time, in the movement of the cars and the scissors mechanism they cause the folding of the canvas to bend towards the outside of the slab, dump or wagon and on its sides it does not allow it to be inserted into its interior because of a strap that contains a memory and is installed at the lower ends along the canvas.
Para proteger la mercancía a transportar, de filtración de agua y/o aire o cualquier otro elemento externo, el mecanismo retráctil de la invención cuenta además, en la parte delantera, con un frente fijo sujeto al planchón o remolque el cual va a permitir un sello hermético al unirse con el carro de arrastre delantero que cuenta con unos cierres rápidos instalados en ambos costados. En la parte trasera cuenta con unos tensores fijos que van sujetos a la estructura del planchón, volco o vagón para obtener una buena tensión en la lona. To protect the merchandise to be transported, from water and / or air filtration or any other external element, the retractable mechanism of the invention also has, in the front part, a fixed front attached to the slab or trailer which will allow a hermetic seal when joining with the front drag carriage that has quick fasteners installed on both sides. In the back it has fixed tensioners that are attached to the structure of the slab, dump or wagon to obtain a good tension on the canvas.
El carro de arrastre trasero, cuenta con una cortina tipo auto-enrollable donde en su parte inferior a todo lo ancho de la misma lleva un tubo que sirve de guía, permitiendo ser accionada en forma manual por una manivela. El fin de esta manivela es poder enrollar la cortina sobre el eje inferior de la misma, y al estar totalmente recogida pueda ser fácilmente ubicada sobre la parte superior de la lona el sello total de la cortina se consigue por medio de veleros en los costados inferiores laterales de la misma. The rear drag carriage has a self-winding curtain where in its lower part the entire width of it carries a tube that serves as a guide, allowing it to be manually operated by a crank. The purpose of this crank is to be able to wind the curtain on the lower axis of the same, and being fully collected it can be easily located on the top of the canvas the total seal of the curtain is achieved by means of sailboats on the lower sides sides of it.
Por último el mecanismo retráctil de lonas para cubrir planchones voleos o vagones de la invención, permite que los carros puedan ser desplazados hacia delante, hacia tras o al centro, para facilitar el cargue o descargue. Finally, the retractable canvas mechanism to cover volley slabs or wagons of the invention allows the cars to be moved forward, backward or to the center, to facilitate loading or unloading.

Descripción detallada de la invención Detailed description of the invention
Como se puede observar en las figuras el mecanismo de la invención está previsto para la recogida y extendida de una lona (11 ) destinada a cubrir mercancías en planchones, voleos o vagones. As can be seen in the figures, the mechanism of the invention is provided for the collection and extension of a tarp (11) intended to cover goods in slabs, volleys or wagons.
El mecanismo retráctil de lonas para cubrir planchones, voleos o vagón de la invención, consiste en la disposición sobre la parte superior del planchón, volco o vagón, de una serie de carros de dos tipos: carros de arrastre, delantero y trasero (2) y carros intermedios (3) dispuestos transversalmente equidistantemente entre sí. Los carros constituyen conjuntamente el soporte de apoyo para la lona (11 ) que cubre la mercancía, pudiéndose desplazar dichos carros mediante rieles (1 ) dispuestos en las dos partes laterales del planchón, volco o vagón. The retractable canvas mechanism to cover slabs, volleys or wagons of the invention consists in the arrangement on the upper part of the slab, dump or wagon, of a series of cars of two types: drag cars, front and rear (2) and intermediate cars (3) arranged transversely equidistant from each other. The cars together constitute the support support for the canvas (11) that covers the merchandise, said cars being able to move by means of rails (1) arranged on the two lateral parts of the slab, dump or wagon.
Tanto los carros de arrastre como los carros intermedios cuentan con medios de rodadura. En su pie se encuentra una base rectangular (3.1 ) provista de ruedas de Nylon (5.1 ) y rodamientos (5.2) que se encajan o montan en rieles (1 ) dispuestos a lo largo de las partes laterales del planchón, volcó ó vagón, a nivel y linealmente correctos, para que se deslicen los carros. Both drag cars and intermediate cars have rolling means. On its foot is a rectangular base (3.1) provided with Nylon wheels (5.1) and bearings (5.2) that fit or mount on rails (1) arranged along the side parts of the slab, tipped or wagon, to level and linearly correct, so that the cars slide.
El riel (1 ) está conformado por una canal en forma de "C" (1.1 ), y aletas dobladas a 90° en la parte superior e inferior, el cual hace de guía para el movimiento de las ruedas en forma vertical. En la aleta inferior cuenta con una canal en forma de "U" (1.2) inversa con unas aletas dobladas a 90° a su costados, el cual, guía el rodamiento en forma horizontal para darle una mayor estabilidad y garantizar un buen movimiento en las fuerzas horizontales y verticales ejercidas por la persona que realiza el carpado y descarpado del planchón, volcó o vagón; The rail (1) is formed by a "C" shaped channel (1.1), and fins folded at 90 ° at the top and bottom, which acts as a guide for the movement of the wheels vertically. In the lower fin it has an inverse "U" (1.2) channel with fins folded at 90 ° at its sides, which guides the bearing horizontally to give it greater stability and ensure good movement in the horizontal and vertical forces exerted by the person who performs the carpating and unloading of the slab, overturned or wagon;
Las ruedas de nylon (5.1 ) se desplazan por el riel (1.1 ) en forma vertical y los rodamientos sobre el riel (1.2)en forma horizontal. Instalados en esta forma se consigue comunicar el movimiento de apertura y cierre de los carros (2) y (3) logrando que el conjuntopueda actuar por la acción de los carros de arrastre (2). Esta acción o fuerza es ejercida por una persona en forma manual y desde el piso haciendo el desplazamiento hacia adelante, al centro, o hacia atrás según sea su conveniencia. The nylon wheels (5.1) move along the rail (1.1) vertically and the bearings on the rail (1.2) horizontally. Installed in this way, it is possible to communicate the opening and closing movement of the carriages (2) and (3), so that the assembly can act by the action of the carriages (2). This action or force is exerted by a person manually and from the floor making the movement forward, to the center, or backwards according to his convenience.
Para el repliegue de la lona el mecanismo de la invención cuenta además con mecanismos tipo tijera (4), conformados por dos piezas diagonales (4.1 ) y (4.2), acoplados en sus extremos inferiores a los costados inferiores (3.2) de los carros (2) y (3) mediante tornillos los cuales permiten su oscilación, la parte superior va sujeta a la lona por medio de veleros, El mecanismo tipo tijera (4) relaciona entre si los carros, este mecanismo está dispuesto de tal manera que cada carro recibe una pareja de diagonales como se entiende mejor en la Fig.7, con el fin de unirlos de forma que cuando los carros se juntan por medio de un impulso provocado por una persona, la pareja de diagonales se cierra en su articulación y se juntan, esto hace que por ir en posición diagonal este lleve más longitud y la hace prolongar, lo que permite estirar y contraer la lona, de tal forma que al movimiento de los carros de arrastre delantero o trasero tiran o empujan los demás. A su vez.el mecanismo tipo tijera (4) provoca que el repliegue de la lona se doble hacia el exterior del planchón, volco o vagón y no a su interior por causa de un fleje que contiene una memoria y que va instalado en los extremos inferiores a todo lo largo de la lona (11 ). For the folding of the canvas, the mechanism of the invention also has scissor-type mechanisms (4), consisting of two diagonal pieces (4.1) and (4.2), coupled at their lower ends to the lower sides (3.2) of the carriages ( 2) and (3) by means of screws which allow its oscillation, the upper part is attached to the canvas by means of sailboats, The scissor mechanism (4) relates the carriages to each other, this mechanism is arranged in such a way that each car receives a pair of diagonals as best understood in Fig. 7, in order to join them so that when the cars are joined by means of an impulse caused by a person, the pair of diagonals is closed in their joint and they are joined , this means that by going in a diagonal position it takes more length and makes it extend, which allows the canvas to be stretched and contracted, so that the movement of the front or rear drag cars pulls or pushes the others. In turn, the scissor-type mechanism (4) causes the folding of the canvas to bend towards the outside of the slab, dump or wagon and not inside because of a strap that contains a memory and is installed at the ends inferior to the entire length of the canvas (11).
Cada una de las piezas diagonales (4.1 ) y (4.2) van atornilladas en la platina (3.2) de los carros de arrastre (2), y carros intermedios (3) a lado y lado tal como se muestra en la figura 3 y van asegurados con un tornillo" y tuerca de seguridad para darle oscilación. Cada extremo de las piezas diagonales (4.1 ) (4.2) del mecanismo tipo tijera (4) están unidas a los carros y las siguientes parejas de piezas diagonales (4.1 ) y (4.2) van unidas a los siguientes carros (3) y así sucesivamente.. Each of the diagonal pieces (4.1) and (4.2) are screwed onto the plate (3.2) of the drag carriages (2), and intermediate carriages (3) side and side as shown in figure 3 and are secured with a screw "and lock nut to give it a swing. Each end of the diagonal pieces (4.1) (4.2) of the scissor type mechanism (4) are attached to the carriages and the following pairs of diagonal pieces (4.1) and (4.2) are attached to the following cars (3) and so on.
La lona (11 ) va sujeta a los carros de arrastres delantero y trasero (2) por su periferia por medio de un conjunto de tornillos autoperforantes con arandela y entre la lona y los tornillos lleva una cinta reata para evitar el rasgado de la lona (11 ) y en los demás carros (3) y mecanismo tipo tijera (4) están sujetos con veleros. The canvas (11) is attached to the front and rear drag cars (2) by its periphery by means of a set of self-drilling screws with washer and between the canvas and the screws it has a straight tape to avoid tearing the canvas ( 11) and in the other cars (3) and scissor mechanism (4) they are held with sailboats.
El carro de arrastre delantero (2) crea un sello evitando la filtración de aire, agua o cualquier otra elemento externo con un frente fijo (7) instalado en la parte delantera. The front drag carriage (2) creates a seal preventing the filtration of air, water or any other external element with a fixed front (7) installed in the front.
A su vez este carro de arrastre (2) posee unos cierres rápidos (6) Instalados en sus costados del carro de arrastre delantero (2) y a la base fija del frente (7), haciendo el ejercicio de accionamiento de amarre entre el carro de arrastre delantero (2) y el frente fijo (7). In turn, this drag carriage (2) has quick fasteners (6) Installed on its sides of the front drag carriage (2) and at the fixed front base (7), doing the mooring drive exercise between the carriage front drag (2) and fixed front (7).
El mecanismo de la invención en su parte trasera cuenta con unos tensores (9) que van sujetos a la estructura del planchón, volco o vagón por medio de una cavidad que se ajusta al perfil de la base del tensor.EI carro de arrastre trasero (2), cuenta con una cortina (8) tipo auto-enrollable donde en su parte inferior a todo lo ancho de la misma lleva un tubo que sirve de guía permitiendo ser accionada por una manivela (13).
