Description

SILLA ARMABLE DE FÁCIL ENSAMBLE Y ALTO SOPORTE  ARMABLE CHAIR OF EASY ASSEMBLY AND HIGH SUPPORT
ESTRUCTURAL  STRUCTURAL
La presente invención se relaciona con una silla armable, la cual cuenta con una estructura fabricada en un material altamente resistente, preferiblemente en acero o fibra de carbono, la cual tiene una base que se une con una porción intermedia, preferiblemente con forma sustancialmente redondeada, con el fin de ajustarse a la forma de las piernas del usuario para su comodidad, y donde dicha porción intermedia se conecta con una porción superior sustancialmente recta con un ángulo de inclinación menor a 20°, donde dicha porción superior es una sola pieza continua compuesta por un tubo doblado que se ensambla a la parte superior de la porción intermedia. The present invention relates to an arm chair, which has a structure made of a highly resistant material, preferably in steel or carbon fiber, which has a base that joins an intermediate portion, preferably with substantially rounded shape, in order to conform to the shape of the user's legs for comfort, and where said intermediate portion is connected with a substantially straight upper portion with an inclination angle of less than 20 °, where said upper portion is a single continuous composite part by a bent tube that is assembled to the top of the intermediate portion.
La silla armable de la presente invención es de fácil ensamble y además debido a su forma y al material de la estructura interna, tiene una alta resistencia para cualquier tipo y tamaño de usuarios. La silla además se envuelve en una tela, preferiblemente una tela flexible, con el fin de permitir que cuando el usuario se sienta en ella, haya una deformación de la tela y así ésta se ajusta a la forma de dicho usuario, suministrando así la comodidad y el confort deseados. The armchair of the present invention is easy to assemble and also due to its shape and the material of the internal structure, it has a high resistance for any type and size of users. The chair is also wrapped in a fabric, preferably a flexible fabric, in order to allow when the user sits on it, there is a deformation of the fabric and thus it conforms to the shape of said user, thus providing comfort and comfort desired.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el estado de la técnica existe una pluralidad de sillas que se pueden ensamblar para ser instaladas en el sitio deseado, donde dichas sillas se ajustan a las necesidades de los usuarios a los cuales se dirigen. Sin embargo, i también existe una necesidad evidente por un tipo de mobiliario, el cual permita ser desarmado y armado de forma fácil, y donde el mismo pueda ser transportado de forma adecuada y rentable para poder llevar a cabo una producción en masa, es decir, donde el medio de transporte pueda ser cualquier vehículo, ya que el empaque del mobiliario es de una tamaño reducido. In the state of the art there is a plurality of chairs that can be assembled to be installed at the desired site, where said chairs conform to the needs of the users to which they are directed. However There is also an obvious need for a type of furniture, which allows it to be disassembled and assembled easily, and where it can be transported properly and profitably to be able to carry out a mass production, that is, where the medium of transport can be any vehicle, since the packaging of the furniture is of a reduced size.
En este sentido, existe una serie de divulgaciones en la técnica enfocadas a sillas desarmables que se ajustan a la forma del usuario. Así, el documento AR069556 divulga una silla reposera que cuenta con una estructura tubular, preferiblemente de acero, asociada a una pieza textil que, envainada en los travesaños superior e inferior de la misma, se extiende para definir su asiento y respaldo. La estructura de esta silla está compuesta por tres pares de tramo tubulares, sustancialmente iguales dos a dos, que se acoplan, por sus extremos para el armado y desarmado de la misma, comprendiendo además, un par de travesaños que definen el ancho de la estructura, un par de largueros de apoyo inferior y un par de tramos tubulares de respaldo que se extienden entre los de apoyo inferior y el travesaño inferior. Sin embargo, la silla descrita en este documento requiere de una transporte especial, toda vez que no es completamente desarmable, haciendo su proceso de fabricación y transporte poco rentable, ya que se requiere de un espacio muy amplio para llevar a cabo dicho transporte. Además, la forma de esta silla requiere de un sistema de recubrimiento en tela especial, toda vez que la tela no puede ser deslizada por la estructura, sino que por el contrario debe ser fabricada a la medida y su instalación corresponde a un proceso tedioso y complicado para un usuario medio, lo cual además requiere de un técnico especializado para instalarla. De otra parte, el documento ES2090526 se refiere a un sillón reclinable modular y su método de ensamble, donde dicho sillón incluye un mecanismo de actuación simplificado que reduce de forma significativa la complejidad y el peso del sistema al tiempo que suministra una comodidad mejorada al usuario. El sillón comprende un par de miembros laterales del bastidor que tienen una serie de taladros alineables formados en el interior, un eje de soporte suspendido desde el primer conjunto de taladros alineados, una varilla de accionamiento suspendida del segundo conjunto de taladros alineables y que se extiende transversal mente entre dichos miembros laterales del bastidor, un conjunto de apoyo de las piernas del usuario suspendido desde dicho eje de soporte, un conjunto de asiento que tiene un asiento, un respaldo de asiento desmontable y medios de articulación oscilantes para conectar el respaldo y el asiento. In this sense, there is a series of disclosures in the art focused on disassembled chairs that fit the user's shape. Thus, document AR069556 discloses a lounge chair that has a tubular structure, preferably of steel, associated with a textile piece that, wrapped in the upper and lower crossbars thereof, extends to define its seat and backrest. The structure of this chair is composed of three pairs of tubular sections, substantially equal two to two, that are coupled, at their ends for the assembly and disassembly thereof, also comprising a pair of crossbars that define the width of the structure , a pair of lower support stringers and a pair of tubular backup sections extending between the lower support and the lower crossbar. However, the chair described in this document requires a special transport, since it is not completely disassembled, making its manufacturing and transportation process unprofitable, since a very large space is required to carry out said transport. In addition, the shape of this chair requires a special fabric covering system, since the fabric cannot be slid by the structure, but instead must be Made to measure and its installation corresponds to a tedious and complicated process for an average user, which also requires a specialized technician to install it. On the other hand, document ES2090526 refers to a modular recliner and its assembly method, where said chair includes a simplified actuation mechanism that significantly reduces the complexity and weight of the system while providing improved user comfort . The chair comprises a pair of side frame members that have a series of adjustable holes formed inside, a support shaft suspended from the first set of aligned holes, a drive rod suspended from the second set of adjustable holes and extending transversely between said lateral members of the frame, a support assembly of the user's legs suspended from said support axis, a seat assembly having a seat, a removable seat backrest and oscillating articulation means for connecting the backrest and the seat.
La invención descrita en esta anterioridad tiene una principal desventaja, la cual se basa en que el mobiliario corresponde a una silla bastante compleja con una pluralidad de elementos que requieren una única instalación por medio de un técnico especializado, lo cual no permite que dicha silla pueda ser transportada y desarmada de forma fácil, limitando así su campo de aplicación y aumentando los costos, tanto de producción, como de ensamble y transporte de la silla. Ahora bien, el documento AR073192 divulga una silla desarmable, la cual permite llevar a cabo un armado y desarmado sencillo, con solo un destornillador y sin necesidad de experiencia o capacidad alguna, con las ventajas de traslado que el desarme de un mueble produce. La silla descrita en este documento comprende dos primeros cuerpos longiformes laterales unidos por medio de por lo menos tres segundos cuerpos longiformes a modo de travesaños mediante elementos de unión que pasan a través de los primeros cuerpos longiformes y se fijan a los extremos de dichos segundos cuerpos longiformes. The invention described herein has a main disadvantage, which is based on the fact that the furniture corresponds to a rather complex chair with a plurality of elements that require a single installation by means of a specialized technician, which does not allow said chair to be transported and disassembled in an easy way, thus limiting its field of application and increasing the costs, both of production, of assembly and transport of the chair. However, document AR073192 discloses a disassembled chair, which allows simple assembly and disassembly, with only a screwdriver and without the need for any experience or capacity, with the advantages of transfer that the disassembly of a furniture produces. The chair described in this document comprises two first lateral longiform bodies joined by means of at least three second longiform bodies as crossbars by means of joining elements that pass through the first longiform bodies and are fixed to the ends of said second bodies Longiforms
Sin embargo, la silla descrita en este documento presenta una principal desventaja basada en los cojines que deben ser ubicados en su parte superior para poder proporcionar comodidad a un usuario, ya que dichos cojines son elementos rígidos que requieren de un transporte y una fabricación muy especializada y que se adapta a la forma de la silla como tal, lo cual convierte la silla en un mobiliario fijo y que no puede ser armado y desarmado de forma sencilla para ser transportada por el mismo usuario a cualquier tipo de locación. Finalmente, el documento AR042965 se relaciona con una silla articulada, plegable y desarmable, cuyo respaldo es la funda para guardarla y transportarla. La silla descrita en este documento se caracteriza porque la estructura espacial que la conforma está constituida con barras o bielas articuladas entre sí, las cuales en la posición desplegada forman dos triángulos paralelos unidos entre sí por dos bielas diagonales, donde dichos triángulos son determinados por las patas anteriores y posteriores. Las patas anteriores se prolongan en su extremo superior por donde se deslizan los soportes del asiento y se introducen en las vainas del respaldo. Así las cosas, es evidente que existe en el estado del arte una necesidad por diseñar e implementar una silla armable con una estructura lo suficientemente rígida y resistente que puede ser usada por usuarios de cualquier tipo y tamaño, donde dicha silla pueda ser transportada de una forma fácil y adecuada, lo cual hace que su proceso de fabricación y la silla como tal sean rentables y los costos puedan ser reducidos, teniendo en cuenta que el ensamble y desensamble de la misma pueda ser realizada por el mismo usuario y no por un técnico especializado. However, the chair described in this document presents a main disadvantage based on the cushions that must be located in its upper part to be able to provide comfort to a user, since said cushions are rigid elements that require a very specialized transportation and manufacturing and that adapts to the shape of the chair as such, which converts the chair into fixed furniture and cannot be assembled and disassembled in a simple way to be transported by the same user to any type of location. Finally, document AR042965 relates to an articulated, folding and disassembled chair, whose back is the cover for storage and transport. The chair described in this document is characterized in that the spatial structure that forms it is constituted with bars or connecting rods articulated with each other, which in the deployed position form two parallel triangles joined together by two diagonal connecting rods, where said triangles They are determined by the anterior and posterior legs. The forelegs extend into their upper end where the seat supports slide and are inserted into the backrest sheaths. Thus, it is evident that in the state of the art there is a need to design and implement an armchair with a sufficiently rigid and resistant structure that can be used by users of any type and size, where said chair can be transported from a easy and proper way, which makes its manufacturing process and the chair as such cost effective and costs can be reduced, taking into account that the assembly and disassembly of the same can be done by the same user and not by a technician specialized.
Adicionalmente, se requiere que la silla armable esté recubierta por un material que permita su adaptación a la forma del usuario, con lo cual se suministra la comodidad y el confort deseados, donde dicho material de recubrimiento de la silla sea una tela flexible de fácil instalación y que se deslice a través de los tubos que forman la estructura de la silla y no se requiera de ningún tipo de costura o unión de la tela para ayudar en la facilidad de instalación del mobiliario. Additionally, it is required that the armchair be covered by a material that allows its adaptation to the user's shape, which provides the desired comfort and comfort, where said chair covering material is a flexible fabric of easy installation and that it slides through the tubes that form the structure of the chair and does not require any sewing or joining of the fabric to help in the ease of installation of the furniture.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓN La silla armable (1 ) de la presente invención comprende las siguientes partes o componentes: DETAILED DESCRIPTION OF THE INVENTION The arm chair (1) of the present invention comprises the following parts or components:
• una sección inferior (2) compuesta por dos tubos (21 ) doblados que tienen una forma particular la cual es plana (21 1 ) en la parte más inferior y circular (212) en la parte superior, donde dicha parte circular (212) corresponde a la sección intermedia de la silla (1 ) y donde la parte plana (21 1 ) más inferior corresponde al componente que sirve de soporte de la silla (1 ) con el piso; • a lower section (2) composed of two bent tubes (21) having a particular shape which is flat (21 1) in the lower part and circular (212) in the upper part, where said circular part (212) corresponds to the intermediate section of the chair (1) and where the lower flat part (21 1) corresponds to the component that serves as the chair support (1) with the floor;
• un soporte horizontal (3) que corresponde a un tubo que conecta los tubos (21 ) de la sección inferior (2) en la parte plana (21 1 ) para dar soporte, rigidez y estabilidad a la silla (1 );  • a horizontal support (3) corresponding to a tube that connects the tubes (21) of the lower section (2) to the flat part (21 1) to give support, rigidity and stability to the chair (1);
• una sección superior (4) formada por un soporte superior (41 ) que se forma a partir de un tubo doblado en sus extremos, donde cada uno de los extremos de dicho soporte (41 ) se une a cada uno de los tubos doblados (21 ) en la parte superior (212) de la sección inferior (2) de la silla (1 ); y  • an upper section (4) formed by an upper support (41) that is formed from a bent tube at its ends, where each of the ends of said support (41) joins each of the bent tubes ( 21) in the upper part (212) of the lower section (2) of the chair (1); Y
• un recubrimiento en tela (5) que cubre la parte circular (212) de la sección inferior (2), el soporte horizontal (3) y la sección superior (4) y que es el encargado de dar soporte a la silla (1 ) para poder soportar un usuario de cualquier tamaño, donde dicha tela (5) se fija en el soporte horizontal (3) y la sección superior (4) pasando dichos elementos de la silla (1 ) a través de ella.  • a fabric covering (5) covering the circular part (212) of the lower section (2), the horizontal support (3) and the upper section (4) and which is responsible for supporting the chair (1 ) to be able to support a user of any size, where said fabric (5) is fixed on the horizontal support (3) and the upper section (4) passing said elements of the chair (1) through it.
Así las cosas, la parte plana (21 1 ) de la sección inferior (2) es completamente recta, es decir, no tiene ningún ángulo de inclinación con relación a la horizontal, teniendo en cuenta el hecho que es la parte que soporta la totalidad de la silla (1 ) y más específicamente, el peso del usuario que se siente sobre ella. Por lo tanto, se requiere que toda la sección inferior (2), especialmente la parte plana (21 1 ) sea resistente y que la unión entre los tubos (21 ) doblados sea realizada por medio de algún medio de fijación que permita que la sección inferior (2) sea un elemento rígido. Thus, the flat part (21 1) of the lower section (2) is completely straight, that is, it has no inclination angle in relation to the horizontal, taking into account the fact that it is the part that supports the whole of the chair (1) and more specifically, the weight of the user who sits on it. Therefore, it is required that the entire lower section (2), especially the flat part (21 1) be resistant and that the joint between the bent tubes (21) is carried out by means of some fixing means that allows the lower section (2) to be a rigid element.
En una modalidad preferida de la invención, los tubos doblados (21 ) no se encuentran de forma paralela y tienen un ángulo de inclinación entre sí, que corresponde al mismo ángulo de inclinación que se presenta al interior del soporte superior (41 ) de la sección superior (4), tal como se puede ver en la figura 5. Ahora bien, los tubos doblados (21 ) en la parte circular (212) están dispuestos de forma tal que no están paralelos entre sí y además, forman una figura tal que tiene sus dos extremos inferior y superior paralelos y los extremos laterales son curvos hacia adentro, tal como se muestra en la figura 6. La forma de esta parte circular (212) permite que el recubrimiento de tela (5) que se encuentra sobre dicha parte circular (212) tenga una resistencia mayor a la que se presenta en la sección superior (4) y que la forma circular se ajuste a la forma de la parte interna de las piernas del usuario para suministrar comodidad y confort mejorados. Así mismo, la forma de la sección circular (212) permite que la instalación del recubrimiento de tela (5) sea realizado de forma fácil, ya que permite que la tela (5) sea deslizada por la estructura, al no tener puntas rectas que lleven a que la tela (5) se rompa o se desgarre. En una modalidad preferida de la invención, la unión entre el tubo doblado (21 ) en su parte circular (212) con el soporte superior (41 ) se lleva a cabo por medio de ensamble entre tubos tal como por medio de tornillos, pasadores de seguridad o ensamble prisionero, preferiblemente con ensamble prisionero, donde el diámetro externo de los tubos (21 , 41 ) es igual, pero donde el soporte superior (41 ) cuenta con una porción que sobresale del mismo y cuyo diámetro es menor al de los dos tubos (21 , 41 ), toda vez que éste ingresa en los tubos doblados (21 ) para poder realizar la sujeción y el ajuste de las partes de la silla (1 ), bien sea por un tornillo que lo atraviesa o por el prisionero, como se indicó anteriormente. In a preferred embodiment of the invention, the bent tubes (21) are not parallel and have an angle of inclination to each other, corresponding to the same angle of inclination that is presented inside the upper support (41) of the section upper (4), as can be seen in figure 5. Now, the bent tubes (21) in the circular part (212) are arranged such that they are not parallel to each other and also form a figure such that it has its two lower and upper ends parallel and the lateral ends are curved inwards, as shown in figure 6. The shape of this circular part (212) allows the fabric covering (5) that is located on said part Circular (212) has a greater resistance to that presented in the upper section (4) and that the circular shape conforms to the shape of the inner part of the user's legs to provide improved comfort and comfort. Likewise, the shape of the circular section (212) allows the installation of the fabric covering (5) to be carried out easily, since it allows the fabric (5) to slide through the structure, as it does not have straight points that lead the fabric (5) to break or tear. In a preferred embodiment of the invention, the connection between the bent tube (21) in its circular part (212) with the upper support (41) is carried out by means of assembly between tubes such as by means of screws, pins safety or prisoner assembly, preferably with prisoner assembly, where the external diameter of the tubes (21, 41) is the same, but where the upper support (41) has a protruding portion thereof and whose diameter is smaller than the two tubes (21, 41), whenever it enters the bent tubes (21) to be able to hold and adjust the parts of the chair (1), either by a screw that passes through it or by the prisoner, as stated above.
De otra parte, el ensamble entre los tubos doblados (21 ) en su sección plana (21 1 ) con el soporte horizontal (3) se realiza por medio de un tornillo en cada extremo de dicho soporte (3), donde cada tornillo atraviesa el tubo doblado (21 ) correspondiente en su sección plana (21 1 ) y es atornillado en cada extremo del soporte horizontal (3). Por lo tanto, para poder realizar este acople entre los tubos doblados (21 ) y el soporte horizontal (3) se requiere que dicho soporte (3) sea curvo en sus extremos con el fin que el acople sea sustancialmente hermético y los elementos coincidan en forma, específicamente en su contorno. On the other hand, the assembly between the bent tubes (21) in its flat section (21 1) with the horizontal support (3) is carried out by means of a screw at each end of said support (3), where each screw crosses the corresponding bent tube (21) in its flat section (21 1) and is screwed on each end of the horizontal support (3). Therefore, to be able to make this coupling between the bent tubes (21) and the horizontal support (3) it is required that said support (3) be curved at its ends so that the coupling is substantially hermetic and the elements coincide in shape, specifically in its outline.
En este sentido, la estructura total de la silla (1 ) como tal, está conformada por la sección inferior (2), el soporte horizontal (3) y la sección superior (4), donde la estructura es fabricada en un material resistente, preferiblemente un material metálico, tal como acero, aunque se pueden usar otros materiales resistentes tal como fibra de carbono, guadua, madera pos formada, o materiales compuestos. Adicionalmente, dicha silla (1 ) se forma por medio del recubrimiento de tela (5) que pasa por la estructura total, quedando sus extremos fijos en el soporte horizontal (3) y el soporte superior (41 ). Finalmente, el recubrimiento de tela (5) corresponde a un elemento que recubre la sección circular (212) de la sección inferior (2) y la sección superior (4), tal como se indicó anteriormente, y que es una tela fabricada de un material flexible, con el fin que se pueda adaptar fácilmente a la forma de la estructura de la silla (1 ) y que facilite su instalación, donde el material flexible además reduce alergias por no uso de materiales como espumas que puede propagarlas. In this sense, the total structure of the chair (1) as such is formed by the lower section (2), the horizontal support (3) and the upper section (4), where the structure is made of a resistant material, preferably a metallic material, such as steel, although other resistant materials such as carbon fiber, guadua, post-formed wood, or materials can be used compounds. Additionally, said chair (1) is formed by means of the fabric covering (5) that passes through the total structure, its ends being fixed on the horizontal support (3) and the upper support (41). Finally, the fabric covering (5) corresponds to an element that covers the circular section (212) of the lower section (2) and the upper section (4), as indicated above, and which is a fabric made of a flexible material, so that it can be easily adapted to the shape of the chair structure (1) and that facilitates its installation, where the flexible material also reduces allergies by not using materials such as foams that can spread them.
Opcionalmente, el recubrimiento de tela (5) puede contar en su superficie inferior que se encuentra ubicada en la sección superior (4) con un par de argollas que permiten estirar la tela por medio de un tensor (6) que se conecta a otro par de argollas que se ubica en el extremo distal de cada uno de los tubos doblados (21 ) en la parte plana (21 1 ), con el fin de suministrar a la silla (1 ) una sección hundida que ayuda a que el usuario se pueda sentar y ayuda en la estética de la misma. Optionally, the fabric covering (5) can have on its lower surface that is located in the upper section (4) with a pair of rings that allow the fabric to be stretched by means of a tensioner (6) that is connected to another pair of rings that are located at the distal end of each of the bent tubes (21) in the flat part (21 1), in order to provide the chair (1) with a sunken section that helps the user to sit and help in the aesthetics of it.
