Description

DISPOSITIVO PARA EL ACCIONAMIENTO DE TOLDOS DE CAMTONES. REMOLQUES Y SIMILARES. DEVICE FOR THE OPERATION OF CAMTONES FOLDS. TRAILERS AND SIMILAR.
El presente modelo de utilidad se refiere a un dispositivo para el accionamiento de toldos de camiones, remolques y similares, que permite extender y/o recoger el toldo de forma automática, sin necesidad de tener que montarlo o desmontarlo manualmente.The present utility model refers to a device for driving awnings of trucks, trailers and the like, which allows to extend and / or pick up the awning automatically, without having to mount or disassemble it manually.
Los toldos de camiones y en general de cualquier vehículo de carga pueden constituir en muchos casos un gran obstáculo para las operaciones de carga y descarga, siendo necesario proceder a su recogida para facilitar estas operaciones, por ejemplo mediante aparatos de carga.The awnings of trucks and in general of any cargo vehicle can be in many cases a great obstacle to loading and unloading operations, being necessary to collect them to facilitate these operations, for example by means of loading devices.
La recogida y posterior extendido del toldo de forma manual, supone un trabajo engorroso y que requiere cierto tiempo, debido a los anclajes o elementos de sujeción necesarios.The collection and subsequent extended of the awning of manual form, supposes a cumbersome work and that requires some time, due to the necessary anchors or elements of subjection.
Por otro lado, debido a que los toldos deben ir soportados por una armadura, generalmente compuesta por arcos o cerchas transversales, la recogida del toldo no es suficiente para disponer de toda la superficie libre, ya que los arcos o cerchas atraviesan la caja y pueden constituir un obstáculo para el manejo de la carga. También pueden disponerse los arcos o cerchas de modo que sean desmonta¬ bles, pero aumentan el trabajo y tiempo de apertura y cierre del toldo. El objeto del presente modelo de utilidad es desarrollar un dispositivo para el accionamiento de toldos en camiones y vehículos de carga en general, mediante el cual pueda extenderse o recogerse el toldo de forma automática, al mismo tiempo que se consigue el desplazamiento en el sentido adecuado de los arcos o cerchas transversales que soportan el toldo. De este modo, cuando se desea recoger el toldo, se consigue el plegado de la lona y el desplazamiento de los arcos o cerchas, hasta lograr su agrupamiento bajo la lona plegada, quedando la caja totalmente descubiert--- y libre para llevar a cabo las operaciones de carga y descarga sin que exista obstáculo alguno. Del mismo modo, para cubrir el vehículo, se desplazan la lona y arcos o cerchas conjuntamente, hasta lograr el desplegado total del conjunto, en el cual los arcos o cerchas quedan posicionados correctamente para soportar la lona. El dispositivo de la invención comprende dos carriles o guías longitudinales que discurren a lo largo de los laterales de la caja, por encima de las paredes longitudinales de la misma. Sobre cada uno de estos carriles o guías van montados, en igual número en ambos lados, carrillos que pueden desplazarse a lo largo de las guías. Entre cada dos carriles enfrentados, uno de cada lado, discurre un arco o cercha transversal rígida, mientras que entre cada dos cerchas consecutivas van dispuestos brazos plegables que quedan en posición alineada cuando la lona está extendida, cubriendo todo el vehículo, y se pliegan al recoger la lona.On the other hand, because the awnings must be supported by an armor, generally composed of arches or transverse trusses, the collection of the awning is not sufficient to have the entire free surface, since the arches or trusses cross the box and can constitute an obstacle to cargo handling. Arches or trusses can also be arranged so that they are removable, but they increase the work and opening and closing time of the awning. The purpose of this utility model is to develop a device for driving awnings in trucks and cargo vehicles in general, by means of which the awning can be extended or picked up automatically, at the same time that the displacement is achieved in the proper direction of the transverse arches or trusses that support the awning. In this way, when it is desired to collect the awning, the folding of the canvas and the displacement of the arches or trusses are achieved, until it is grouped under the folded canvas, leaving the box fully discovered --- and free to carry out loading and unloading operations without any obstacle. In the same way, to cover the vehicle, the canvas and arches or trusses are moved together, until the total deployment of the assembly is achieved, in which the arches or trusses are correctly positioned to support the canvas. The device of the invention comprises two rails or longitudinal guides that run along the sides of the box, above the longitudinal walls thereof. On each of these rails or guides are mounted, in equal numbers on both sides, carriages that can be moved along the guides. Between each two facing rails, one on each side, runs a rigid transverse arch or truss, while between each two consecutive trusses foldable arms are arranged that are aligned when the canvas is extended, covering the entire vehicle, and fold to the Pick up the canvas.
La lona que configura el toldo, compuesta por una lámina flexible, va fijada sobre los brazos plegables antes citados.The canvas that configures the awning, composed of a flexible sheet, is fixed on the folding arms mentioned above.
Los carrillos de uno y otro lado quedan relacionados mediante sendos cables que van fijados al carrillo posterior y que se prolongan a partir de los carrillos extremos en porciones que se conectan a tambores que enrollan y desenrollan sincronizadamente en sentido contrario las porciones de uno y otro extremo, efectuando de este modo el plegado y desplegado del toldo, incluyendo la lona o lámina flexible de cubrición y los arcos o cerchas transversales.The carriages on either side are connected by means of two cables that are fixed to the rear carriage and that extend from the end carriages into portions that are connected to drums that wind and unwind synchronously in the opposite direction the portions of both ends , thereby folding and unfolding the awning, including the canvas or flexible covering sheet and the transverse arches or trusses.

El toldo 2 instalado en la caja del camión de las figuras 1 y 2 incluye una estructura plegable, la cual va montada sobre dos carriles o guías longitudinales 3, cada una de las cuales va situada por encima del tablero lateral 4 del vehículo, en posición coplanaria con el mismo. Estos carriles o guías pueden estar constituidos por dos perfiles tubulares paralelos. La estructura plegable citada está constituida por dos series de caπillosIn figures 1 and 2 a truck is shown whose box 1 is covered by a canopy 2, this awning being in the deployed position in figure 1, completely covering the box 1 of the truck, while in figure 2 it is in the folded position or pick up The awning 2 installed in the truck box of figures 1 and 2 includes a folding structure, which is mounted on two rails or longitudinal guides 3, each of which is located above the side panel 4 of the vehicle, in position coplanar with it. These rails or guides may consist of two parallel tubular profiles. The aforementioned folding structure is constituted by two series of caps
5 montados en las guías o carriles 3, incluyendo las dos series igual número de carrillos, situados en posiciones transversalmente enfrentadas. Como mejor se aprecia en las figuras 6 y 7, cada carrillo 5 lleva fijado superiormente una columna 6. Cada dos columnas consecutivas 6 pertenecientes a carrillos de un mismo lado van unidas mediante un conjunto de brazos plegable 7, figuras 6 y 7. Las columnas pertenecien¬ tes a carrillos 5 enfrentados de uno y otro lado quedan relacionadas entre sí mediante un arco o cercha transversal 8, figuras 4 y 5. Cada dos arcos o cerchas consecutivas van además relacionados entre sí por un conjunto de brazos plegables intermedios 9. De este modo, la estructura plegable incluye los arcos o cerchas transversales 9 que quedan relacionados entre sí a través de los conjuntos de brazos plegables extremos 7 e intermedio 9 y quedan montados sobre los carrillos 5, a través de las columnas 6.5 mounted on the guides or rails 3, including the two series equal number of rails, located in transversely facing positions. As best seen in figures 6 and 7, each carriage 5 has a column 6 fixed on top. Each two consecutive columns 6 belonging to carriages on the same side are joined by a set of folding arms 7, figures 6 and 7. The columns belonging to 5 facing carriages on either side are related to each other by a cross arch or truss 8, figures 4 and 5. Each two consecutive arches or trusses are also interrelated by a set of intermediate folding arms 9. Thus, the folding structure includes the transverse arches or trusses 9 that are related between yes through the sets of folding arms 7 and intermediate ends 9 and are mounted on the carriages 5, through the columns 6.
Las dos series de carrillos quedan relacionados entre sí mediante sendos cables 10 que van fijados al carrillo que ocupa la posición extrema posterior y se prolongan a partir de los carrillos extremos en porciones que se conectan a tambores 11 que enrollan y desenrollan sincronizadamente en sentido contrario las porciones 12 y 13 de uno y otro extremo.The two series of carriages are connected to each other by means of two cables 10 that are fixed to the carriage that occupies the rear end position and extend from the end carriages into portions that are connected to drums 11 that wind and unwind synchronously in the opposite direction. portions 12 and 13 of both ends.
En la posición representada en la figura 3, el tambor 11 gira de modo que vaya enrollando la porción 12 y desenrollando la porción 13, con lo cual los carrillos se desplazan en la dirección B, en la que los conjuntos 7 y 9 de brazos van adoptando la posición plegada referenciada con los números 7a y 9a en la figura 3, quedando los carrillos 5 correspondientes adosados entre sí. Cuando se desea plegar la estructura el tambor 11 girará en sentido contrario, fraccionando entonces del tramo 13 y soltando o liberando el tramo 12, con lo que los carrillos 5 se desplazan en sentido opuesto al de la flecha B. La lona o lámina flexible del toldo irá fijada a los arcos o cerchas 8, siendo arrastrada por dichos arcos en los desplazamientos ya descritos, obteniéndose así de un modo automático, mediante la activación del tambor 11 , el desplegado total de la estructura y lona, hasta conseguir la cubrición total de la caja del vehículo, tal y como se representa en la figura 1 , o bien el plegado de la lona y estructura en la parte anterior de la caja, dejando el resto de la misma totalmente libre para efectuar las operaciones de carga y descarga.In the position shown in Figure 3, the drum 11 rotates so that it is winding the portion 12 and unwinding the portion 13, whereby the carriages move in the direction B, in which the arm assemblies 7 and 9 go adopting the folded position referenced with the numbers 7a and 9a in figure 3, the corresponding carriages 5 being attached to each other. When it is desired to fold the structure, the drum 11 will rotate in the opposite direction, then fractionating the section 13 and releasing or releasing the section 12, whereby the carriages 5 move in the opposite direction to that of the arrow B. The canvas or flexible sheet of the awning will be fixed to the arches or trusses 8, being dragged by said arcs in the displacements already described, thus obtaining in an automatic way, by activating the drum 11, the total unfolding of the structure and canvas, until the total covering of the vehicle box, as shown in figure 1, or the folding of the canvas and structure in the front part of the box, leaving the rest of it completely free to carry out loading and unloading operations.
El conjunto de brazos plegables 7 y 9 puede estar constituido por dos parejas-de brazos 1.4, que van articulados entre sí por uno αe sus extremos, mientras que por el opuesto se articulan, uno de ellos a las columnas 6 y el opuesto a un cuerpo intermedio 15. A través de este cuerpo puede discurrir el cable 10 que relaciona cada serie de carrillos. Como se aprecia en las figuras 8 y 9, cada uno de los carrillos 5 puede estar constituido por dos placas paralelas 16, entre las que van montados cuatro ejes transversales 17, portadores de ruedas 18 que apoyan sobre el perfil 19 que define el carril o guía 3. Las placas 16 van unidas mediante una placa superior 17 y disponen en sus cantos verticales de orejetas 20 entre las que se montan rodillos 21 de giro libre, de eje vertical, que apoyan sobre las superficies verticales del perfil 19.The set of folding arms 7 and 9 can be constituted by two pairs-of arms 1.4, which are articulated with each other by one of its ends, while on the opposite they are articulated, one of them to columns 6 and the opposite of a intermediate body 15. Through this body can run the cable 10 that relates each series of carriages. As can be seen in Figures 8 and 9, each of the carriages 5 can be constituted by two parallel plates 16, between which four transverse axes 17, wheel carriers 18 that rest on the profile 19 defining the rail or are mounted guide 3. The plates 16 are connected by means of an upper plate 17 and are arranged in their vertical edges of lugs 20 between which free-rotating rollers 21, of vertical axis, which rest on the vertical surfaces of the profile 19 are mounted.
De este modo, los carrillos 5 apoyan sobre las superficies horizontales superior e inferior del perfil y también sobre las superficies verticales del mismo, evitando todo riesgo de cabeceo y asegurando un buen deslizamiento longitudinal sobre el mismo.In this way, the carriages 5 rest on the upper and lower horizontal surfaces of the profile and also on the vertical surfaces thereof, avoiding any risk of pitching and ensuring a good longitudinal sliding on it.
Los cables 10 que relacionan los carrillos 5 de uno y otro lado apoyan sobre poleas posteriores 22 y anteriores 23 de cambio de dirección.The cables 10 that relate the carriages 5 on either side rest on rear pulleys 22 and previous 23 of direction change.
El tambor 11 irá accionado mediante un motor, con cambio de sentido de giro, de modo que mediante la puesta en funcionamiento en el sentido adecuado se logre la recogida o desplegado del toldo, junto con la estructura que soporta el mismo.The drum 11 will be driven by a motor, with change of direction of rotation, so that by putting it into operation in the proper direction, the collection or unfolding of the awning is achieved, together with the structure that supports it.
Como se aprecia en las figuras 3 y 4, a lo largo de cada pareja de brazos 9 puede discurrir un cable 24, que se fija al cuerpo intermedio 15 de dichos brazos y se conecta por sus extremos a los muelles 25. Este sistema servirá para tensar y mantener a los brazos 9 en posición horizontal.As can be seen in Figures 3 and 4, a cable 24 can run along each pair of arms 9, which is fixed to the intermediate body 15 of said arms and connected at its ends to the springs 25. This system will serve to tension and keep arms 9 horizontal.
En las figuras 10 y 1 1 se muestra una posible forma de sujeción lateral de la lona o lámina flexible de cubrición, que se referencia con el número 26. Los bordes longitudinales de esta lona o lámina flexible llevan fijados poleas 27 y 28, a diferente altura, entre las que pasa un cordón elástico 29. Por debajo de las poleas 28 dispone además de parejas de poleas 30 que están destinadas a discurrir sobre una carrilera 31 fijada longitudinalmente en los laterales de la caja del vehículo.In Figures 10 and 1 1 a possible form of lateral support of the canvas or flexible covering sheet is shown, which is referred to with the number 26. The longitudinal edges of this canvas or flexible sheet have pulleys 27 and 28 fixed, to different height, between which an elastic cord 29 passes. Below the pulleys 28 it also has pairs of pulleys 30 which are intended to run on a rail 31 fixed longitudinally on the sides of the vehicle case.
Con la constitución comentada, durante las operaciones de plegado de la estructura, el cordón elástico 29 facilita el plegado de los laterales de la lona.With the constitution mentioned, during the operations of folding the structure, the elastic cord 29 facilitates the folding of the sides of the canvas.
En las figuras 12 a 14 se muestra un posible sistema de cierre y amarre posterior de la lona, con el que no es necesario que el operario trepe para efectuar las operaciones de amarre. La lona o lámina de cubrición puede incluir dos o tres mecanismos como los representados en cada lado, dependiendo de la altura del camión.Figures 12 to 14 show a possible closure and back tie system of the canvas, with which it is not necessary for the operator to climb to perform the mooring operations. The canvas or cover sheet can include two or three mechanisms such as those represented on each side, depending on the height of the truck.
Las figuras 12 a 14 incluyen un mecanismo de apriete o amarre de la lona, el cual irá montado al menos en el perfil 31 correspondiente al pie posterior de los laterales de la caja del camión. Este mecanismo está compuesto por dos llantas de apriete, una lateral referenciada con el número 32 y otra posterior referenciada con el número 33, que van articuladas mediante bisagras 34. Entre estas llantas y el perfil 31 se ajusta el lateral de la lona 26 y la lona trasera 26a. La llanta 32 lleva fijados pasadores 35 que penetran en el perfil 31 y quedan rematados en una cabeza 36 entre la cual y un asiento 37 va montado un resorte de compresión 38 que impulsa al pasador 35 hacia la posición mostrada en la figura 13. El perfil 31 lleva también montada una palanca 39 dotada de una patilla interna 40 enfrentada a la cabeza 36 del vastago 35.Figures 12 to 14 include a mechanism for tightening or tying the canvas, which will be mounted at least on the profile 31 corresponding to the rear foot of the sides of the truck body. This mechanism is composed of two clamping wheels, one side referenced with the number 32 and another rear referenced with the number 33, which are articulated by hinges 34. Between these tires and the profile 31 the side of the canvas 26 is adjusted and the rear canvas 26a. The rim 32 has fixed pins 35 that penetrate the profile 31 and are finished off in a head 36 between which and a seat 37 is mounted a compression spring 38 that drives the pin 35 towards the position shown in Figure 13. The profile 31 also has a lever 39 fitted with an internal pin 40 facing the head 36 of the rod 35.
Desplazando la palanca 39 hacia la posición mostrada en la figura 14, la patilla 40 empuja hacia el exterior al pasador 35, con lo cual la llanta 32 se separa del perfil 31. Al mismo tiempo la llanta 33, mediante la articulación 34, se abre parcialmente, liberando la lona posterior 26a.By moving the lever 39 towards the position shown in Figure 14, the pin 40 pushes the pin 35 outwards, whereby the tire 32 is separated from the profile 31. At the same time the tire 33, by means of the articulation 34, opens partially, releasing the rear canvas 26a.
Al soltar la palanca 39, ésta recupera la posición de la figura 13, merced al resorte 38. La escuadra 41 provoca el giro de la llanta 33, al pasar el mecanismo de una a otra posición.When the lever 39 is released, it recovers the position of figure 13, thanks to the spring 38. The square 41 causes the wheel 33 to rotate, when the mechanism is passed from one position to another.
Las figuras 13 y 14 corresponden al mecanismo del lado izquierdo de la caja, siendo el del lado derecho de igual constitución, pero ocupando una posición simétrica. Los brazos plegables 6 pueden disponer de un muelle que los impulse hacia la posición de plegado, mediante los cuales se asegura el inicio del movimiento de estos brazos en el sentido correcto de plegado.Figures 13 and 14 correspond to the mechanism on the left side of the box, the one on the right side being of the same constitution, but occupying a symmetrical position. The folding arms 6 can have a spring that drives them towards the folded position, by means of which the start of the movement of these arms in the correct folding direction is ensured.
La lona 26 puede disponer de piezas de refuerzo de plástico en los laterales, situadas de modo que cooperen y faciliten su plegado durante el proceso de recogida de la estructura. Además la lona puede incluir piezas de articulación para su conexión a los brazos plegables 7 que ayudarán al plegado de la lona. The canvas 26 can have plastic reinforcement pieces on the sides, positioned so that they cooperate and facilitate their folding during the process of collecting the structure. In addition, the canvas can include articulation pieces for connection to the folding arms 7 that will help the folding of the canvas.
