Abstract

The invention relates to a collapsible system comprising a tubular body formed by collapsible units. Curved and straight prefolds are marked out in order to form the collapsible units. When an axial force is exerted thereon, the prefolds contract, reducing the length of the tubular body such that one end of the tube closes to form a cone-like structure and the other end opens so that the cone can be inserted therein, thereby dissipating the force applied. In addition, the system can return to the original shape thereof depending on the material used. The collapsible units can be applied to any material that can be used to form a cylindrical body, such as metal, plastic or paper. The invention can be used, for example, to dissipate force in a collision between two bodies housing the above system therebetween or as a system for compacting packages and containers.

ANTECEDENTESBACKGROUND
En la actualidad existen artículos elaborados con predobleces con distintas aplicaciones, como: las patentes FR 2,729,640 y US 3,474,844 que se refieren a la compactación de botellas de PET desechables, para disminuir el espacio que estas ocupan al ser desechadas. Dichas patentes consisten en que sobre la botella que simula un cuerpo tubular donde se proyectan líneas transversales y paralelas con la finalidad de comprimir la botella a manera de acordeón. La diferencia respecto a la presente invención es que el cuerpo tubular que tiene proyectadas unidades colapsables a base de predobleces curvos y rectos, se inserta en si mismo, haciendo que la longitud del cuerpo tubular diminuya y con esto disipar la fuerza aplicada. Adicionalmente el cuerpo tubular con predobleces curvos y rectos, una vez que ha sido compactado se auto sujeta, es decir, no regresa a su estado inicial a menos de que se le aplique una fuerza contraria a la compactación. Una de las aplicaciones de la presente invención es colocarla entre el chasis y la defensa de un vehículo, funcionando preferentemente como absorbedor de energía cinética al momento de una colisión. En esta aplicación se conoce la patente ES2147472-A1, misma que consiste en la distribución de cortes verticales en un tubo y que al ser impactado se expande radialmente, con la diferencia de que en la presente invención el cuerpo tubular se pliega contrayéndose en si mismo disipando la fuerza aplicada.At present there are articles made with pre-difficulties with different applications, such as: patents FR 2,729,640 and US 3,474,844 that refer to the compaction of disposable PET bottles, to reduce the space they occupy when they are discarded.

La presente invención, motivo de esta solicitud, consiste en configurar en un cuerpo tubular de material plegable, recto o con ligera conicidad, con geometría circular, elíptica, poligonal o combinación de estas, unidades colapsables preferentemente equidistantes formando un sistema colapsable. Para proyectar el sistema colapsable es necesario dividir el cuerpo tubular en mínimo dos áreas adyacentes en donde la línea divisoria es perpendicular al eje (las áreas son denominadas "A" y "B"), y sobre estas se realizan predobleces curvos y rectos (ver figura 1); y cortes curvos. Los predobleces formados con líneas curvas y rectas, en las áreas "A" y "B" sirven de guía para el sistema colapsable y su marcación está determinada por el tipo de material a trabajar. Es decir, en el caso de papeles gruesos o cartoncillos y algunos plásticos como el polipropileno y algunos otros polímeros, la marcación se puede hacer por el proceso de inyección, soplado, rotomoldeado, o suajado; en el caso de los metales laminados, el proceso adecuado sería el troquelado y rolado o doblado; y en algunas casos la marcación de los predobleces adicionalmente presenta perforaciones o cortes. Cabe señalar que dependiendo del material seleccionado el sistema colapsable puede regresar a su geometría original después de haber ejercido una fuerza axial.The present invention, reason for this application, consists of configuring a tubular body of foldable material, straight or with slight conicity, with circular, elliptical, polygonal geometry or combination of these, preferably equidistant collapsible units forming a collapsible system. In order to project the collapsible system it is necessary to divide the tubular body into at least two adjacent areas where the dividing line is perpendicular to the axis (the areas are called "A" and "B"), and on these curved and straight preforms are performed (see Figure 1); and curved cuts. Predobleces formed with curved and straight lines, in areas "A" and "B" serve as a guide for the collapsible system and its marking is determined by the type of material to work. That is, in the case of thick papers or paperboard and some plastics such as polypropylene and some other polymers, the marking can be done by the process of injection, blowing, rotomolding, or softening; in the case of rolled metals, the proper process would be die cutting and rolling or bending; and in some cases the marking of the predobles additionally presents perforations or cuts. It should be noted that depending on the material selected, the collapsible system may return to its original geometry after exerting an axial force.
Al aplicar una fuerza axial sobre el cuerpo tubular, los predobleces de las unidades colapsables localizadas en el área "A" se pliegan, y simultáneamente los predobleces del área "B" se doblan adoptando una forma similar a la de un cono que se inserta por su punta en el área "A" lo cual ocasiona una disminución en la longitud del cuerpo tubular. El sistema colapsable guiado por líneas curvas y rectas en cuerpos tubulares propuesto en este invento, tiene aplicaciones diversas; como almacenamiento, en empaques y/o envases; posición de uso, formando parte o el todo de la estructura de muebles, juguetes, pantallas para lámparas y; específicamente se hace mención como elemento estructural en los automóviles, preferentemente localizado entre el chasis y la defensa, ya que funciona como disipador de fuerza al momento de un choque; así como una técnica de compactación para botellas de PET. Es importante resaltar que el material del cual esta hecho el cuerpo tubular esta en función de la aplicación.By applying an axial force on the tubular body, the pre-woes of the collapsible units located in the "A" area are folded, and simultaneously the predobles of the "B" area are folded adopting a shape similar to that of a cone that is inserted by its tip in the area "A" which causes a decrease in the length of the tubular body. The collapsible system guided by curved and straight lines in tubular bodies proposed in this invention has diverse applications; as storage, in packages and / or containers; position of use, forming part or all of the structure of furniture, toys, lampshades and; Specifically, mention is made as a structural element in automobiles, preferably located between the chassis and the defense, since it functions as a force dissipator at the time of a crash; as well as a compaction technique for PET bottles. It is important to highlight that the material from which the tubular body is made is depending on the application.
El invento consiste en realizar y distribuir de una manera determinada en un cuerpo tubular mínimo dos unidades colapsables preferentemente equidistantes a manera transversal, que conforman un sistema colapsable que permite el colapso del mismo cuerpo tubular de una manera predeterminada por las unidades colapsables. Las unidades colapsables comprenden una combinación entre cortes curvos, la proyección de predobleces curvos y rectos; así como una pluralidad de perforaciones, en las 2 áreas axiales adyacentes definidas como "A" y "B" del cuerpo tubular (Ver figura 1). Existe una línea fronteriza transversal entre las áreas "A" y "B", para proyectar una unidad colapsable en el cuerpo tubular (ver figura 2) la línea fronteriza antes descrita, comprende la unión de dos predobleces, el primero de ellos denominado valle fronterizo (1) que se predobla en valle, simulando una hendidura; es decir doblar el material hacia el observador, sobre la línea y es perpendicular al eje del cuerpo tubular; y el otro predoblez, denominado montaña fronterizo (2) que se predobla en montaña, propiciando que se levante el material y esto consiste en doblar el material hacia el lado contrario del observador, sobre la línea y también es perpendicular al eje del cuerpo tubular. Sobre una de las áreas, a la que denominaremos: área "A" se presenta: una sección en arco combinada (20), denominada así porque comprende al menos dos predobleces en montaña (25 y 26) y un corte en arco (27); en adelante a esta sección, la denominaremos, como "SAC" (ver figura 3).The invention consists in carrying out and distributing in a determined manner in a minimum tubular body two collapsible units preferably equidistant in a transverse manner, which form a collapsible system that allows the collapse of the same tubular body in a predetermined manner by the collapsible units. Collapsible units comprise a combination between curved cuts, the projection of curved and straight predobles; as well as a plurality of perforations, in the 2 adjacent axial areas defined as "A" and "B" of the tubular body (See figure 1). There is a transverse border line between areas "A" and "B", to project a collapsible unit in the tubular body (see figure 2) the border line described above, includes the union of two predobles, the first of them called the border valley (1) that is pre-folded in the valley, simulating a cleft; that is, to bend the material towards the observer, on the line and is perpendicular to the axis of the tubular body; and the other predoblez, called the border mountain (2) that is pre-folded in the mountain, causing the material to be lifted and this consists in bending the material towards the opposite side of the observer, over the line and is also perpendicular to the axis of the tubular body. On One of the areas, which we will call: area "A", is presented: a combined arc section (20), named this way because it comprises at least two mountain predoots (25 and 26) and an arc cut (27); hereinafter we will call this section, as "SAC" (see figure 3).
En el área adyacente al área "A", denominada como área "B", se presentan una serie de predobleces ligeramente curvos u oblicuos que se describen de la siguiente manera: el predoblez valle oblicuo (5) se predobla en valle y es oblicuo al eje del cuerpo tubular, y pasa por la mediatriz (11) del predoblez montaña fronterizo (2) y se extiende hasta un punto indefinido (12) a la izquierda del observador e interno al predoblez montaña en arco (3), se extiende también hacia la derecha del observador en el área "B" y es interrumpido al momento de su intersección (10) con un predoblez montaña oblicuo (6) que se predobla en montaña y es oblicuo al eje del cuerpo tubular (que en la figura se encuentra a la derecha del observador con respecto al predoblez montaña en arco (3). Éste último predoblez montaña oblicuo (6) inicia en la intersección (13) del predoblez montaña en arco (3) y el predoblez valle fronterizo (1).In the area adjacent to the area "A", referred to as area "B", a series of slightly curved or oblique predobles are presented as described: the oblique valley predoble (5) is pre-folded in the valley and is oblique to the axis of the tubular body, and passes through the mediatrix (11) of the border mountain predoble (2) and extends to an indefinite point (12) to the left of the observer and internal to the arc mountain predoble (3), also extends towards the right of the observer in the area "B" and is interrupted at the moment of its intersection (10) with an oblique mountain predoble (6) that is pre-folded in the mountain and is oblique to the axis of the tubular body (which in the figure is the right of the observer with respect to the arched mountain predoble (3) The latter oblique mountain predoble (6) begins at the intersection (13) of the arched mountain predoble (3) and the border valley predoble (1).
Teniendo como eje de simetría una línea imaginaria paralela al eje que pasa por la mediatriz del predoblez montaña fronterizo (2), se proyectan en espejo los 2 predobleces oblicuos anteriormente mencionados, quedando estos como a continuación se describe: El predoblez valle oblicuo espejo (7), que se predobla en valle y es oblicuo al eje del cuerpo tubular y en espejo al predoblez valle oblicuo (5) y pasa por la mediatriz (11) del predoblez montaña fronterizo (2) y se extiende hasta un punto indefinido (14) a la derecha del observador e interno al predoblez montaña en arco (3), se extiende también hacia la izquierda en el área "B" y es interrumpido al momento de su intersección (9) con un predoblez montaña oblicuo espejo (8), que se predobla en montaña, es oblicuo al eje del cuerpo tubular y en espejo al predoblez montaña oblicuo (6). Éste último predoblez montaña oblicuo espejo (8) (que en la figura se encuentra a la izquierda del observador con respecto al predoblez montaña en arco) inicia en la intersección (4) entre el predoblez montaña en arco (3) y el predoblez valle fronterizo (1) de la unidad colapsable vecina.Having as an axis of symmetry an imaginary line parallel to the axis that passes through the mediatrix of the border mountain predoble (2), the 2 oblique predobles mentioned above are projected in mirror, leaving these as described below: The mirror oblique valley predoble (7 ), which is pre-folded in the valley and is oblique to the axis of the tubular body and in a mirror to the oblique valley predoble (5) and passes through the mediatrix (11) of the border mountain predoble (2) and extends to an indefinite point (14) to the right of the observer and internal to the arched mountain predoble (3), it also extends to the left in area "B" and is interrupted at the time of its intersection (9) with a mirror oblique mountain predoble (8), which is pre-folded in mountain, is oblique to the axis of the tubular body and in mirror to the oblique mountain predoble (6). The latter oblique mirror mountain predoble (8) (in the figure to the left of the observer with respect to the arched mountain predoble) begins at the intersection (4) between the arched mountain predoble (3) and the border valley predoble (1) from the neighboring collapsible unit.
Las intersecciones (9) y (10) de cada unidad colapsable están alineadas; (debido a la imagen de espejo) pero pueden estar sin alinear respecto a las mismas intersecciones de los unidades colapsables vecinas. La figura 3, es la representación del sistema colapsable en su variación de SAC en el área "A" y predobleces curvos y rectos en el área "B"; la figura 4, es una representación del sistema colapsable mostrado en la figura 3, que se muestra totalmente colapsado sobre la marcación previamente propuesta al ejercer sobre el cuerpo tubular una fuerza axial. La figura 5, es una vista superior del sistema colapsable de la figura 3 en su estado original.The intersections (9) and (10) of each collapsible unit are aligned; (due to the mirror image) but they may not be aligned with respect to the same intersections of neighboring collapsible units. Figure 3 is the representation of the collapsible system in its variation of SAC in the "A" area and curved and straight predoots in the "B" area; Figure 4 is a representation of the collapsible system shown in Figure 3, which is fully collapsed on the previously proposed marking when exerting an axial force on the tubular body. Figure 5 is a top view of the collapsible system of Figure 3 in its original state.
Es importante resaltar que los predobleces curvos y rectos, proyectados en las áreas "A" y "B", pueden ser sustituidos por una pluralidad de perforaciones que opcionalmente son circulares (Ver figura 6), lineales (Ver figura 7) o combinación de estos (Ver figura 8), la pluralidad de perforaciones alineadas a la proyección montaña en arco, se le denominada como perforaciones montaña en arco lineales (21) o perforaciones montaña en arco circulares (24). La figura 9 muestra el cuerpo tubular de la figura 7 al plegarse totalmente sobre la marcación propuesta, al ejercer una fuerza axial. Las perforaciones montaña en arco lineales (21) y circulares (24); y el predoblez montaña en arco (3), inician en la intersección del predoblez valle fronterizo (1) y el predoblez montaña fronterizo (2) y termina en la intersección (4) entre el predoblez montaña fronterizo (2) de esta unidad y valle fronterizo (1) de la unidad vecina.It is important to highlight that curved and straight predobles, projected in areas "A" and "B", can be replaced by a plurality of perforations that are optionally circular (See figure 6), linear (See figure 7) or combination of these (See figure 8), the plurality of perforations aligned to the arc mountain projection, is referred to as linear arc mountain perforations (21) or circular arc mountain perforations (24). Figure 9 shows the tubular body of Figure 7 when fully folded over the proposed marking, when exerting an axial force. Linear (21) and circular (24) arc mountain perforations; and the arched mountain predoble (3), begin at the intersection of the border valley predoble (1) and the border mountain predoble (2) and ends at the intersection (4) between the border mountain predoble (2) of this unit and valley border (1) of the neighboring unit.
El primer predoblez en montaña (25) sigue la curvatura de la SAC (20), e inicia en la intersección que se forma entre el predoblez valle fronterizo (1) y el predoblez montaña fronterizo (2); y termina en un punto paralelo a la mitad de la distancia que existe entre la mediatriz (11) y el punto mas alto de la SAC; y es en este punto, donde inicia el corte (27), que se realiza siguiendo la curvatura de la SAC y termina en el punto equidistante del lado opuesto, para dar inicio al segundo predoblez montaña (26), que es la proyección en espejo del primer predoblez montaña (25).The first mountain predoble (25) follows the curvature of the SAC (20), and begins at the intersection that forms between the border valley predoble (1) and the border mountain predoble (2); and ends at a point parallel to half the distance between the mediatrix (11) and the highest point of the SAC; and it is at this point, where the cut begins (27), which is done following the curvature of the SAC and ends at the equidistant point on the opposite side, to start the second mountain predoble (26), which is the mirror projection of the first mountain predoblez (25).
Considerando que los cortes en arco (20), las perforaciones montaña en arco (21) y los predobleces montaña en arco (3) pueden variar su forma geométrica en sus repeticiones transversales así como en las axiales. Las filas de unidades colapsables a lo largo del sistema pueden variar de posición transversal respecto a la primera, y pueden estar o no invertidas a manera de espejo.Considering that arc cuts (20), mountain arc perforations (21) and mountain arc predobles (3) can vary their geometric shape in their transverse repetitions as well as in axial ones. The rows of collapsible units along the system may vary in transverse position with respect to the first, and may or may not be inverted as a mirror.
Las figura 10a, 10b y 10c, representan algunas de las etapas del plegado del sistema colapsable en la variante de predobleces curvos y rectos, donde en la figura 10a se puede apreciar una etapa inicial del cuerpo tubular cuando empieza a recibir una fuerza axial, en la figura 10b se observa la etapa intermedia del cuerpo tubular al seguir recibiendo la fuerza axial y plegarse sobre la marcación propuesta (considerando para efectos del presente invento, que la marcación es representativa mas no limitativa, y puede hacerse referencia al sistema colapsable con las variantes con corte en arco, perforaciones montaña en arco y tal como se representa en las figuras, a los predobleces curvos y rectos); en la figura 10c se muestra la etapa de plegado total del sistema colapsable sobre la marcación propuesta al recibir una fuerza axial. La figura 11, presenta una opción para la proyección de predobleces oblicuos en el área "B" del cuerpo tubular donde la intersección (9) entre los predobleces valle oblicuo espejo (7) y montaña oblicuo espejo (8) (representados en la figura a la izquierda del observador respecto al predoblez montaña en arco) esta en contacto con la intersección (10) de una unidad colapsable vecina y forman un vértice (17) y de igual manera la intersección (10) entre los predobleces valle oblicuo (5) y montaña oblicuo (6) con la intersección (9) de la unidad colapsable vecina forman el vértice (18).Figures 10a, 10b and 10c, represent some of the stages of folding the collapsible system in the variant of curved and straight predobles, where in figure 10a an initial stage of the tubular body can be seen when it begins to receive an axial force, in Figure 10b shows the intermediate stage of the tubular body as it continues to receive the axial force and folds over the proposed marking (considering for the purposes of the present invention, that the marking is representative but not limiting, and reference can be made to the collapsible system with the variants with arc cutting, mountain arc perforations and as shown in the figures, to curved and straight predobles); Figure 10c shows the total folding stage of the collapsible system on the proposed marking when receiving an axial force. Figure 11 presents an option for the projection of oblique predobles in the "B" area of the tubular body where the intersection (9) between the valley oblique mirror predobles (7) and mirror oblique mountain (8) (represented in figure a the left of the observer with respect to the arched mountain predoble) is in contact with the intersection (10) of a neighboring collapsible unit and forms a vertex (17) and similarly the intersection (10) between the oblique valley predobles (5) and oblique mountain (6) with the intersection (9) of the neighboring collapsible unit form the vertex (18).
La figura 12, es una variante en el sistema de predobleces en donde se puede visualizar que el predoblez montaña en arco (3) puede variar en cuanto a su forma geométrica pudiendo ser de forma ovalada, circular, o poligonal, cabe mencionar que el corte en arco (20), y la pluralidad de perforaciones montaña en arco (21) pueden variar su geometría al igual que el predoblez montaña en arco (3).Figure 12, is a variant in the predoble system where it can be seen that the arc mountain predoble (3) can vary in terms of its geometric shape and can be oval, circular, or polygonal, it should be mentioned that the cut in arc (20), and the plurality of mountain arc perforations (21) can vary their geometry like the mountain arc predobility (3).
La figura 13 es una representación del sistema colapsable preferido como disipador de fuerza, al estar localizado perpendicularmente en medio de dos cuerpos que ejercerán sobre el sistema colapsable una fuerza, particularmente el sistema colapsable tiene sección transversal circular (19) en donde todas las unidades colapsables tienen un predoblez montaña en arco con geometría elíptica, y los vértices de los predobleces oblicuos entre las unidades colapsables están separados. La figura 14 muestra el cuerpo tubular de la figura 13 al plegarse sobre la marcación propuesta de predobleces curvos y rectos, una vez que se le ha aplicado una fuerza sobre su eje axial. En la figura 15, podemos observar la vista superior del sistema colapsado en su ejemplo preferido. La figura 16 representa una variante del sistema colapsable de sección transversal circular (22) en donde las filas de unidades colapsables se repiten particularmente tres veces de manera axial.Figure 13 is a representation of the preferred collapsible system as a force dissipator, being located perpendicularly in the middle of two bodies that will exert a force on the collapsible system, particularly the collapsible system has circular cross-section (19) where all the collapsible units they have an arched mountain predoble with elliptical geometry, and the vertices of the oblique predobles between the collapsible units are separated. Figure 14 shows the tubular body of Figure 13 when folded over the proposed marking of curved predobles and straight, once a force has been applied on its axial axis. In Figure 15, we can see the top view of the collapsed system in your preferred example. Figure 16 represents a variant of the collapsible system of circular cross-section (22) in which the rows of collapsible units are particularly repeated three times axially.
La figura 17, muestra una vista isométrica del sistema colapsable preferido. Figure 17 shows an isometric view of the preferred collapsible system.
