Piezas de ensamblaje para estructura automontableAssembly parts for self-assembling structure

La presente invencion, tal y como su nombre indica, se refiere a unas piezas de ensamblaje para una estructura automontable que comprenda una pluralidad de largueros y una pluralidad de travesanos que se ensamblan entre si generando una estructura solida sin necesidad de ningun otro elemento o material de union.The present invention, as its name indicates, refers to assembly parts for a self-assembling structure comprising a plurality of stringers and a plurality of crossbars that are assembled together generating a solid structure without the need of any other element or material. of Union.

La estructura requiere solo de dos tipos de piezas que consiguen conformar y dar solidez a la estructura.The structure requires only two types of pieces that manage to shape and give strength to the structure.

El sector de la tecnica al que pertenece es el de los sistemas de ensamblaje de estructuras. ANTECEDENTES DE LA INVENCIONThe sector of the technique to which it belongs is that of the systems of assembly of structures. BACKGROUND OF THE INVENTION

Si bien el tipo de estructura a la que se aplican las piezas de ensamblaje puede tener multiples usos y aplicaciones, resulta idonea para ser utilizada como pallet de transporte, de hecho es ese un sector en donde se han encontrado los antecedentes mas cercanos y que aquf se comentan.Although the type of structure to which the assembly parts are applied can have multiple uses and applications, it is suitable to be used as a transport pallet, in fact that is a sector where the closest antecedents have been found and here They comment.

Desde antiguo se han venido utilizando los pallets para transportar cargas, sin embargo tales palets deben de realizar diversos viajes sin carga.Since ancient times, pallets have been used to transport loads, however such pallets must make several trips without cargo.

En transportes de larga distancia el coste de vuelta de los pallets, debido a su volumen, hace que sea antieconomica su recuperacion.In long-distance transport the return cost of the pallets, due to its volume, makes its recovery uneconomical.

Tampoco es facil la venta de pallets nuevos a grandes distancias pues el recorrido entre el fabricante y el primer usuario se hace igualmente sin carga.It is also not easy to sell new pallets over long distances because the route between the manufacturer and the first user is also without load.

Para favorecer el transporte de mayor cantidad de pallets en una misma unidad de transporte, como puede ser un camion o un container, se han ideado pallets desmontables, de tal forma que, una vez cumplida su funcion con la carga en un transporte, puedan desmontarse para optimizar el espacio.To favor the transport of more pallets in the same transport unit, such as a truck or a container, removable pallets have been devised, so that, once their function is fulfilled with the load in a transport, they can be disassembled to optimize space.

Los pallets desmontables favorecen tambien la sustitucion de piezas rotas pues en los no desmontables, la rotura de una pieza convierte al pallet en inservible en la mayorla de las ocasiones con el coste economico y medioambiental que ello supone.The removable pallets also favor the replacement of broken pieces because in non-removable ones, the breakage of a piece makes the pallet unusable in most cases with the economic and environmental cost that this entails.

De entre los antecedentes de pallets desmontables encontramos los siguientes:Among the background of removable pallets we find the following:

El modelo de utilidad ES245986 se refiere a un pallet desmontable si bien para dar rigidez al conjunto requiere que los elementos longitudinales queden unidos entre si tanto superior como inferiormente, lo cual eleva el numero de piezas a utilizar en el montaje.The utility model ES245986 refers to a removable pallet, although in order to give rigidity to the assembly, it requires that the longitudinal elements be joined together both superiorly and inferiorly, which increases the number of parts to be used in the assembly.

El modelo de utilidad ES1018770U, se refiere a un pallet desmontable cuyos distintos elementos quedan unidos entre si por una serie de tacos atravesados por unas varillas, requiriendose por tanto tales elementos de union ademas de las piezas longitudinales y transversales que constituyen en si misma la estructura.The utility model ES1018770U, refers to a removable pallet whose different elements are joined together by a series of studs crossed by rods, therefore requiring such joint elements in addition to the longitudinal and transverse parts that constitute the structure itself .

El modelo de utilidad ES1033284U se refiere a un pallet desmontable cuyas piezas se unen entre si gracias a una disposicion tipo sandwich en donde a la pieza central se le han anadidoThe utility model ES1033284U refers to a removable pallet whose pieces are joined together thanks to a sandwich type arrangement where the centerpiece has been added

unas protuberancias aptas para ensamblarse con unos orificios practicados en las piezas exteriores. Esta solucion presenta algunos problemas de fabricacion esencialmente derivados de las protuberancias que deben unirse al liston en una fase posterior asl como problemas de transporte pues la existencia de las protuberancias impide optimizar los espacios en el transporte cuando se lleva el pallet desmontado.protrusions suitable for assembling with holes made in the outer parts. This solution presents some manufacturing problems essentially derived from the protuberances that must be attached to the bar at a later stage as well as transport problems since the existence of the protuberances prevents optimizing the spaces in the transport when the pallet is removed.

El modelo de utilidad ES1018770U se refiere a una pallet automontable configurado en base a una plataforma horizontal que presenta unos recortes a modo de pestana siendo que esas pestanas deben poder deformarse hasta adoptar una posicion vertical, lo cual limita los materiales a los que puede aplicarse esta solucion tecnica.The utility model ES1018770U refers to a self-pallet pallet configured on the basis of a horizontal platform that has cuts like a flange being that these eyelashes must be able to deform until adopting a vertical position, which limits the materials to which this can be applied technical solution

La patente europea EP0516681 publicada en Espana como ES2093698 se refiere a una palet desmontable constituido a base de dos largueros metalicos huecos, enfrentados entre si cuyos lados encarados presentan una serie de orificios aptos para introducir y fijar unos travesanos que presentan en su cara inferior unas ranuras de disposicion y forma adecuada para asentarse sobre las paredes verticales interiores de los largueros dichos. Esta solucion tecnica requiere que los largueros sean metalicos.European patent EP0516681 published in Spain as ES2093698 refers to a removable pallet consisting of two hollow metal stringers, facing each other whose facing faces have a series of holes suitable for introducing and fixing crossbars that have grooves on their underside of disposition and suitable form to settle on the interior vertical walls of the said stringers. This technical solution requires that the stringers be metallic.

La patente estadounidense US2007/0221537 se refiere a una estructura tridimensional realizada a partir de diversas piezas que se ensamblan entre si en donde tales piezas se encuentran realizadas o al menos rellenas de varias capas de carton o papel corrugado. Esta patente requiere, para su ejecucion, varios tipos distintos de piezas. Por otro lado, los ensamblajes generan salientes en la estructura que dificultan el manejo y el almacenamiento del mismo.US Patent US2007 / 0221537 refers to a three-dimensional structure made from various pieces that are assembled together where such pieces are made or at least filled with several layers of cardboard or corrugated paper. This patent requires, for its execution, several different types of parts. On the other hand, assemblies generate protrusions in the structure that make handling and storage difficult.

La patente estadounidense US8113129, se refiere a un pallet formado por distintas piezas, largueros y travesanos, que se ensamblan entre si, estando cada uno de esos largueros y travesanos compuestos por dos piezas que, al unirse, atrapan a la pieza con la que se cruzan y, a su vez, quedan atrapadas con ella. El ensamblaje asl planteado genera salientes que dificultan el manejo y almacenamiento del pallet.US patent US8113129, refers to a pallet formed by different pieces, stringers and crossbars, which are assembled together, each of these stringers and crossbars being composed of two pieces that, when joined, trap the piece with which it they cross and, in turn, get trapped with it. The assembly asl raised generates protrusions that hinder the handling and storage of the pallet.

La patente estadounidense US20 09/0298015 se refiere a un pallet desmontable formado por una serie de piezas, largueros y travesanos, que se cruzan formando el pallet, quedando unidas por clipaje reforzada la union por unas varillas que atraviesan longitudinalmente las piezas una vez montado el pallet. En esta patente se requieren distintas piezas y varillas y, dado el modo de union, se generan salientes que dificultan el manejo y almacenamiento del pallet.US patent 09/0298015 refers to a removable pallet formed by a series of pieces, stringers and crossbars, which intersect forming the pallet, being joined by reinforced clipping the union by rods that cross the pieces longitudinally once assembled the pallet Different parts and rods are required in this patent and, given the way of joining, protrusions are generated that make handling and storage of the pallet difficult.

El propio solicitante es titular de una patente cercana en el estado de la tecnica que es la ES201331602 que supera varios de los problemas expuestos si bien dependiendo del material en que se construya, los travesanos pueden quedar excesivamente debiles por sus rebajes y, por otro lado, los largueros, tal y como estan recogidos en esa patente son excesivamente pesados.The applicant himself is the owner of a nearby patent in the state of the art, which is ES201331602, which overcomes several of the problems presented, although depending on the material in which it is constructed, the crossbars may be excessively weak due to their recesses and, on the other hand , the stringers, as set out in that patent, are excessively heavy.

El pallet no requiere de tornillerla ni elementos adicionales para asegurar sus uniones, ambas cosas muy ventajosas especialmente para el reciclado pues no requiere la fase de desmontaje y separacion de materiales.The pallet does not require a screwdriver or additional elements to ensure its joints, both very advantageous things especially for recycling because it does not require the phase of disassembly and separation of materials.

Este pallet puede realizarse en cualquier material medianamente rlgido y asl se han hecho pruebas en madera, plastico o incluso carton, obteniendose excelentes resultados.This pallet can be made in any medium rigid material and thus tests have been done on wood, plastic or even cardboard, obtaining excellent results.

Por otro lado la simplicidad de sus un uniones hace que con solo dos tipos de piezas, pueda montarse la estructura.On the other hand, the simplicity of their joints means that with only two types of parts, the structure can be assembled.

La estructura automontable se construye a partir de un numero concreto de dos tipos de piezas que, puestas de manera distinta, cumplen distintas funciones en la estructura. Tales piezas son:The self-assembling structure is constructed from a specific number of two types of pieces that, placed differently, fulfill different functions in the structure. Such pieces are:

1. Pieza de larguero que comprende:1. Stringer piece comprising:

a. Una base del larguero que comprende un cuerpo alargado de seccion preferiblemente cuadrangular.to. A base of the stringer comprising an elongated body of preferably quadrangular section.

b. Una corona del larguero en su parte superior que, siendo de menor grosor que el larguero comprende:b. A crown of the stringer in its upper part which, being of smaller thickness than the stringer comprises:

i. Una pluralidad de elementos en forma de "L” invertida en donde cada uno de esos elementos comprenden una pared vertical, una cubierta horizontal dispuesta en el sentido del eje longitudinal del larguero generandose una cavidad interior bajo dicha cubierta horizontal, estando todo ellos alineados, dispuestos en el mismo sentido y distribuidos de manera regular a lo largo del larguero.i. A plurality of inverted "L" shaped elements in which each of these elements comprises a vertical wall, a horizontal cover arranged in the direction of the longitudinal axis of the crossbar generating an inner cavity under said horizontal cover, all of them being aligned, arranged in the same direction and distributed regularly along the crossbar.

ii. Al menos un elemento en forma de "T” que comprende una pared vertical y una cubierta horizontal atravesada, preferiblemente en perpendicular, al eje longitudinal del larguero, generando una cavidad interna a cada lado de la pared horizontal.ii. At least one "T" shaped element comprising a vertical wall and a horizontal cover crossed, preferably perpendicularly, to the longitudinal axis of the crossbar, generating an internal cavity on each side of the horizontal wall.

2. Pieza de travesano que comprende un cuerpo laminar que comprende:2. A cross member comprising a sheet body comprising:

a. Una pluralidad de perforaciones de abrochado. Distinguiremos entre perforaciones A que son las parcialmente cerradas por una pestana a media altura por uno de sus extremos longitud inales y perforaciones B que son las parcialmente cerradas por una pestana a media altura por uno de sus extremos laterales. Las perforaciones se encuentran agrupadas en de dos en dos y cada grupo comprende una perforacion A y una perforacion B preferiblemente dispuesta una a continuacion de la otra. La orientacion de estos grupos se alterna a lo largo del travesano.to. A plurality of buttoned perforations. We will distinguish between perforations A that are partially closed by a mid-height flange by one of its inal length ends and perforations B that are partially closed by a mid-height flange by one of its lateral ends. The perforations are grouped in two by two and each group comprises a perforation A and a perforation B preferably arranged next to each other. The orientation of these groups alternates along the crossbar.

b. Opcionalmente la pieza de travesano puede comprender orificios pasantes distribuidos por sus caras mayores para aligerar la pieza.b. Optionally the crosspiece can comprise through holes distributed on its larger faces to lighten the piece.

La estructura comprende una pluralidad de piezas de larguero y una pluralidad de piezas de travesano cuyo numero final dependera de la configuracion que se le quiera dar a la estructura.The structure comprises a plurality of stringer pieces and a plurality of crossbar pieces whose final number will depend on the configuration that is to be given to the structure.

Las piezas de larguero son de mayor grosor en su base y de menor grosor en su corona, estando los elementos en forma de "L” invertida y "T” preferiblemente en una posicion longitudinalmente centrada.The stringer pieces are thicker at their base and smaller in their crown, the elements being "L" inverted and "T" preferably in a longitudinally centered position.

Para el montaje del pallet, las piezas de larguero se disponen apoyadas sobre su base y con la corona en una posicion superior, dispuestas una con otras en paralelo y espaciadas entre si debiendo estar, al menos una de ellas, en sentido contrario a las demas, es decir, dispuesta en paralelo pero habiendo rotado 180° sobre su eje vertical.For the assembly of the pallet, the stringer parts are arranged supported on its base and with the crown in a superior position, arranged one with the other in parallel and spaced apart from each other, at least one of them must be in the opposite direction to the others. , that is, arranged in parallel but having rotated 180 ° on its vertical axis.

Distinguiremos entre largueros pares e im pares en funcion de su orientacion en donde todos los pares estaran orientados de igual forma y todos los impares en sentido inverso.We will distinguish between even and even stringers depending on their orientation where all the pairs will be oriented in the same way and all the odd ones in the opposite direction.

En una realizacion preferida la estructura comprende 3 piezas de larguero que se alternan estando la central, par, en sentido inverso a las de los laterales, impares.In a preferred embodiment the structure comprises 3 stringer pieces that alternate being the central, even, in the opposite direction to those of the odd sides.

Las piezas de travesano se situan sobre las piezas de larguero haciendo coincidir sus perforaciones A con los elementos en forma de "L” invertida existentes en la corona de los largueros.The crossbar pieces are placed on the stringer pieces by matching their perforations A with the inverted "L" shaped elements existing in the crown of the stringers.

Para permitir la coincidencia de todas las perforaciones A con los elementos en forma de "L” invertida, los largueros pares estaran ligeramente adelantados a los largueros impares.In order to allow all the perforations A to coincide with the inverted "L" shaped elements, the even stringers will be slightly forward to the odd stringers.

Estando las piezas de travesano engarzadas con los elementos en forma de "L” invertida se procede a desplazar el o los largueros pares para enrasarlos longitudinalmente con los impares.The pieces of crossbar being crimped with the elements in the form of an inverted "L", proceed to move the pair (s) to make them longitudinally flush with the odd ones.

De este modo los travesanos quedan abrochados a los largueros pues las cubiertas horizontales de los elementos en forma de "L” invertida quedan sobre las pestanas que cierran parcialmente las perforaciones A quedando dichas pestanas alojadas en las cavidades interiores de tales elementos en forma de "L”.In this way the crossbars are fastened to the stringers because the horizontal covers of the inverted "L" shaped elements remain on the flanges that partially close the perforations A leaving said flanges housed in the interior cavities of such "L" shaped elements. "

Una vez las pestanas que cierran parcialmente las perforaciones A estan alojadas en las cavidades internas de las piezas en forma de "L”, se procede a situar las piezas de travesano restantes sobre la o las zonas donde se encuentran los elementos en forma de "T”, haciendo coincidir tales elementos en forma de "T” con las perforaciones B del travesano. Para que la cubierta horizontal de los elementos en forma de "T” pueda pasar a traves de la zona libre de la perforaciones B, el travesano debe situarse ligeramente desplazado hacia un lateral del conjunto de la estructura para, en un momento posterior, centrarlo y abrocharlo forzando a que las pestanas que cierran parcialmente las perforaciones B queden alojadas en una de las cavidades formadas entre la pared vertical y la cubierta horizontal de los elementos en forma de "T”.Once the flanges that partially close the perforations A are housed in the internal cavities of the "L" shaped pieces, the remaining crossbar pieces are placed on the one or the areas where the "T" shaped elements are located ", Matching such" T "shaped elements with the perforations B of the crossbar. In order for the horizontal cover of the" T "shaped elements to pass through the free area of the perforations B, the crossbar must be positioned slightly displaced to one side of the structure assembly to, at a later time, center it and fasten it, forcing the flanges that partially close the perforations B to be housed in one of the cavities formed between the vertical wall and the horizontal cover of the elements in the form of "T".

La estructura ensamblada mediante este sistema de abrochado en dos direcciones, longitudinal y lateral, queda solidamente montada no siendo posible que un golpe fortuito o un movimiento involuntario provoque el desensamblado.The structure assembled by means of this fastening system in two directions, longitudinal and lateral, is solidly assembled and it is not possible that an accidental hit or an involuntary movement causes disassembly.

Para aligerar la estructura, los travesanos pueden presentar, distribuidos por sus caras mayores, orificios pasantes.To lighten the structure, the crossbars may have, through their larger faces, through holes.

Por otro lado, tambien para aligerar la estructura, los largueros presentan vaciados siendo que algunos de tales vaciados configuran orificios capaces de acoger los elementos de carga de una maquina trasportadora, tal y como pueden ser los patines de una carretilla transportadora.On the other hand, also to lighten the structure, the stringers have emptyings being that some of these emptyings form holes capable of receiving the loading elements of a transporting machine, such as the skates of a conveyor.

La existencia de vaciados o huecos en los pallets es habitual para favorecer el suo de maquinas transportadoras, sin embargo estos vaciados pueden debilitar la estructura o, entre otras limitaciones, hacer que los pallets asl configurados no puedan trasladarse por una lfnea de rodillos.The existence of emptyings or gaps in the pallets is common to favor the suo of conveyor machines, however these empties can weaken the structure or, among other limitations, make the configured pallets can not be moved along a line of rollers.

Para solucionar am bos problem as, la estructura en forma de pallet objeto del presente, comprende un cierre inferior de tales orificios de tal forma que el orifico queda enmarcado e insertado en el cuerpo de los largueros y no meramente, como sucede en otras realizaciones, como un rebaje puntual en forma de arco.To solve both problems, the pallet-shaped structure object of the present, comprises a lower closure of such holes in such a way that the hole is framed and inserted into the body of the stringers and not merely, as in other embodiments, like a punctual arc-shaped recess.

La pieza de larguero par, en este caso la central, se dispone ligeramente adelantada respecto de las anteriores de modo que al ubicar los travesanos (16) sobre los elementos en "L” invertida, la parte abierta de cada perforacion tipo A (15) coincida con la cubierta horizontal de cada "L” invertida (9) de las coronas (6) de los largueros (1).The piece of even stringer, in this case the central one, is arranged slightly ahead of the previous ones so that when locating the crossbars (16) on the inverted "L" elements, the open part of each type A perforation (15) match the horizontal cover of each inverted "L" (9) of the crowns (6) of the stringers (1).

Una vez dispuestos todos los travesanos (16) sobre los elementos tipo "L” invertida e insertados estos elementos en las perforaciones tipo A (15) de los travesanos, se procede a enrasar longitudinalmente los largueros de tal modo que las pestanas tipo A (17) se alojen en las cavidades interiores de los elementos de "L” invertida (10) y asl, al estar los largueros en sentidos opuestos de manera alterna, se genera un abrochado impidiendo que los travesanos puedan moverse, si no es moviendo tambien los largueros, al estar los largueros enfrentados unos con otros.Once all the crossbars (16) are arranged on the inverted "L" type elements and these elements are inserted in the perforations type A (15) of the crossbars, the stringers are longitudinally flush so that the type A flanges (17 ) are housed in the interior cavities of the elements of inverted "L" (10) and thus, being the stringers in opposite directions alternately, a buckle is generated preventing the crossbars from moving, if it is not also moving the stringers , being the stringers facing each other.

No obstante, para evitar que el desplazamiento involuntario de los largueros pudiera provocar el desabrochado, se utiliza un travesano de cierre que siendo geometricamente igual a los demas, su instalacion es sin embargo distinta.However, in order to avoid that the involuntary displacement of the stringers could cause the unfastening, a closing traverse is used that is geometrically equal to the others, its installation is however different.

Este travesano de cierre se ubica haciendo coincidir y alojando en las zonas abiertas de las perforaciones tipo B (18) las cubiertas horizontales de las "T” (13).This closing traverse is located by matching the horizontal covers of the "T" (13) in the open areas of the type B perforations (18).

Una vez esta el travesano como se ha indicado debe quedar ligeramente descuadrado del conjunto sobresaliendo por el lateral de la estructura, procediendose entonces a enrasar dichoOnce the traverse is indicated as indicated, it should be slightly untouched from the assembly protruding from the side of the structure, then proceeding to make this

travesano con el resto lo que provoca que las pestanas tipo B (19) se inserten en las cavidades laterales de la T (14).traverse with the rest which causes the type B eyelashes (19) to be inserted into the lateral cavities of the T (14).
