CAMA Y VICEVERSABED AND VICEVERSA
DESCRIPCIONDESCRIPTION
Objeto de la invencionObject of the invention
La presente invencion se refiere a un sistema de conversion de un mueble para convertir un sofa en cama y viceversa que esta destinado a facilitar las operaciones de conversion de sofa en cama y viceversa. El sistema de conversion ocupa un reducido espacio; destacandose ademas que su instalacion esta ubicada en zonas laterales del mueble, lo que permite poder aprovechar espacios internos del conjunto del mueble para guardar objetos, incluso en dichos espacios internos se pueden montar cajones.The present invention refers to a system of conversion of a piece of furniture to convert a sofa into a bed and vice versa that is intended to facilitate the conversion operations of sofa into bed and vice versa. The conversion system occupies a small space; standing out besides that his installation is located in lateral zones of the piece of furniture, what allows to be able to take advantage of internal spaces of the set of the furniture to keep objects, even in said internal spaces can draw drawers.
Problema tecnico a resolver y antecedentes de la invencionTechnical problem to solve and background of the invention
Actualmente son conocidos fundamentalmente dos tipos de sistemas de conversion de muebles para convertir un sofa en cama y viceversa; donde los muebles incluyen una estructura de somier que es plegable y puede adoptar una primera posicion desplegada para convertir el mueble en cama; y una segunda posicion plegada para convertir el mueble en sofa, donde en esta segunda posicion plegada la estructura de somier esta recogida y oculta dentro de un espacio interior del mueble.Currently, two types of furniture conversion systems are fundamentally known for converting a sofa into a bed and vice versa; where the furniture includes a frame structure that is foldable and can adopt a first deployed position to convert the furniture into a bed; and a second folded position to convert the furniture into a sofa, where in this second folded position the mattress structure is collected and hidden inside an interior space of the furniture.
Para convertir el mueble de sofa en cama se extrae hacia fuera la estructura de somier, bien mediante el arrastre de una parte inferior del sofa, o bien tirando hacia arriba de dicha parte inferior del sofa.To convert the sofa furniture into a bed, the mattress structure is pulled outwards, either by dragging a lower part of the sofa, or by pulling upwards said lower part of the sofa.
El problema de este sistema de conversion radica por un lado, en que la parte baja del mueble esta completamente inhabilitada, es decir, no se puede emplear como zona de almacenamiento, ya que dicha parte baja se necesita para albergar parte de la estructura de somier y/o para poder llevar a cabo el plegado y desplegado de dicha estructura de somier.The problem of this conversion system lies on the one hand, in that the lower part of the furniture is completely disabled, that is, it can not be used as a storage area, since said lower part is needed to house part of the bed frame structure and / or to be able to carry out the folding and unfolding of said bed frame structure.
Por otro lado, estos sistemas de conversion requieren un esfuerzo fisico importante para extraer y volver a guardar la estructura de somier.On the other hand, these conversion systems require an important physical effort to extract and re-store the bed frame structure.
Por ultimo, cabe senalar que en el caso del sistema de conversion en el que se extrae la estructura de somier mediante arrastre (por ejemplo a traves del empleo de ruedas); dicho sistema de conversion posee el inconveniente anadido de que el contacto de las ruedas con el suelo puede rayar la superficie de dicho suelo.Finally, it should be noted that in the case of the conversion system in which the bed structure by dragging (for example, through the use of wheels); said conversion system has the added disadvantage that the contact of the wheels with the ground can scratch the surface of said floor.
Otro tipo de sistema de conversion conocido para convertir un mueble sofa en cama es aquel en el que se abate el respaldo del mueble en modo sofa hacia atras, convirtiendo asi el sofa en cama.Another type of conversion system known to convert a sofa furniture into a bed is one in which the back of the furniture is pushed down in a sofa-like manner backwards, thus converting the sofa into a bed.
El problema de este sistema de conversion descrito en el parrafo anterior radica en que necesariamente el sofa debe estar separado una cierta distancia de una pared para que el respaldo se pueda abatir y poder convertir el sofa en cama. En estos muebles en los que el respaldo es abatible tambien hay que anadir la limitacion en lo que se refiere a la longitud de dicho respaldo y por lo tanto de la cama.The problem with this conversion system described in the previous paragraph is that the sofa must necessarily be separated a certain distance from a wall so that the backrest can be folded down and the sofa converted into a bed. In these furniture in which the backrest is foldable you also have to add the limitation in what refers to the length of said backrest and therefore of the bed.
Asimismo, al hilo de lo dicho en el parrafo anterior, para volver a convertir el modo cama al modo sofa, es preciso levantar desde atras el respaldo con el gran esfuerzo fisico que ello conlleva.Also, in line with what was said in the previous paragraph, in order to convert the bed mode back to the sofa mode, it is necessary to raise the backrest from the back with the great physical effort that this entails.

Sobre el primer bastidor 6 se monta un elemento de asiento 6a y sobre el segundo bastidor 7 se monta un elemento de respaldo 7a.The first seat frame 6 is attached to the first arms 5a by first pieces 15 and the second back frame 7 is attached to the second arms 5b by means of second pieces 16. On the first frame 6 a seat element 6a is mounted and on the second frame 7 a backup element 7a is mounted.
En una realizacion de la invencion el elemento de asiento 6a y el elemento de respaldo 7a son elementos independientes; mientras que en otra realizacion de la invencion el elemento de asiento 6a y el elemento de respaldo 7a son dos elementos que estan unidos entre si mediante un abisagrado; como son por ejemplo dos colchones unidos por una arista comun.In an embodiment of the invention, the seat element 6a and the backrest element 7a are independent elements; while in another embodiment of the invention, the seat element 6a and the backrest element 7a are two elements that are joined together by a hinged one; such as, for example, two mattresses joined by a common edge.
Sobre el primer bastidor 6 de asiento esta fijado un larguero 17 que se utiliza para manipular el sistema de conversion para convertir el sofa en cama o viceversa; donde dicho larguero 17 se encuentra ubicado en correspondencia con un frontal del mueble 1 por donde sobresale el primer bastidor 6 junto con el elemento de asiento 6a en la position desplegada del sistema de la invencion en modo cama.On the first seat frame 6 is fixed a stringer 17 which is used to manipulate the conversion system to convert the sofa into a bed or vice versa; wherein said stringer 17 is located in correspondence with a front of the cabinet 1 through which the first frame 6 together with the seat element 6a projects in the unfolded position of the system of the invention in bed mode.
En una posicion plegada del sistema de conversion en el modo sofa, el segundo bastidor 7 junto con el elemento respaldo 7a estan dispuestos en una posicion sustancialmente vertical, mientras que el primer bastidor 6 junto con el elemento de asiento 6a estan dispuestos en una posicion horizontal.In a folded position of the conversion system in the sofa mode, the second frame 7 together with the backrest element 7a are arranged in a substantially vertical position, while the first frame 6 together with the seat element 6a are arranged in a horizontal position .
En cambio, en una posicion desplegada del sistema de conversion en modo cama, el segundo bastidor 7 junto con el elemento de respaldo 7a estan dispuestos en una posicion horizontal, mientras que el primer bastidor 6 junto con el elemento asiento 6a estan dispuestos tambien en una posicion horizontal sobresaliendo hacia fuera con respecto al frontal del mueble 1.On the other hand, in a deployed position of the conversion system in bed mode, the second frame 7 together with the backrest element 7a are arranged in a horizontal position, while the first frame 6 together with the seat element 6a are also arranged in a horizontal position. horizontal position projecting outwards with respect to the front of the cabinet 1.
Por otro lado, las guias inferiores 2 y las guias superiores 3 estan delimitadas por unos extremos opuestos: unos extremos posteriores y unos extremos anteriores que estan mas proximos al frontal del mueble 1 que los extremos posteriores; donde los extremos anteriores de las gwas superiores 3 forman parte de sus tramos curvados 3b que convergen hacia el frontal del mueble 1 y tambien convergen hacia las guias inferiores 2.On the other hand, the lower guides 2 and the upper guides 3 are delimited by opposite ends: rear ends and front ends that are closer to the front of the furniture 1 than the rear ends; where the front ends of the upper gwas 3 are part of their curved sections 3b that converge towards the front of the cabinet 1 and also converge towards the lower guides 2.
Al hilo de lo dicho en el parrafo anterior, los extremos anteriores de las guias inferiores 2 estan mas proximos al frontal del mueble 1 que los extremos anteriores de las guias superiores 3, de forma que las guias inferiores 2 tienen unos tramos adicionales 2a que sobresalen con respecto a los extremos anteriores de las guias superiores 3; donde dichos tramos adicionales 2a y los tramos arqueados 3b de las guias superiores 3 permiten que los primeros brazos 5a y los segundos brazos 5b de las estructuras articuladas 5 se junten y contacten entre si en la posicion de desplegado en modo cama, consiguiendo que el primer bastidor 6 y el segundo bastidor 7 queden alineados horizontalmente en dicha posicion de desplegado en modo cama.In line with what has been said in the previous paragraph, the front ends of the lower guides 2 are closer to the front of the furniture 1 than the front ends of the upper guides 3, so that the lower guides 2 have additional sections 2a that protrude with respect to the previous ends of the upper guides 3; where said additional sections 2a and the arched sections 3b of the upper guides 3 allow the first arms 5a and the second arms 5b of the articulated structures 5 to come together and contact each other in the unfolding position in bed mode, obtaining that the first frame 6 and second frame 7 are aligned horizontally in said deployed position in bed mode.
Partiendo de la posicion plegada en modo sofa, para transformar al modo cama, se tracciona de dicho larguero17, donde con esta operation se desplazara el primer bastidor 6 y tambien el segundo bastidor 7 hasta alcanzar la posicion de desplegado total en la que los dos bastidores, primero 6 y segundo 7, se colocan en un plano horizontal para conformar una cama formada por el elemento de asiento 6a asociado al primer bastidor 6 y el elemento de respaldo 7a asociado al segundo bastidor 7. En dicha posicion de desplegado total, el elemento de asiento 6a tiene una superficie de apoyo que es coplanaria a otra superficie de apoyo del elemento de respaldo 7a.Starting from the folded position in sofa mode, to transform to the bed mode, said stringer 17 is pulled, where with this operation the first frame 6 and also the second frame 7 are moved until reaching the full unfolding position in which the two frames , first 6 and second 7, are placed in a horizontal plane to form a bed formed by the seat element 6a associated with the first frame 6 and the backing element 7a associated with the second frame 7. In said full unfolding position, the element 6a has a support surface that is coplanar to another support surface of the backrest element 7a.
En la posicion de desplegado total en modo cama, el posicionamiento del segundo bastidor (7) de respaldo se mantiene en una posicion estable gracias a que los segundos brazos (5b) estan en contacto con los primeros brazos (5a) de las dos estructuras articuladas (5).In the fully deployed position in bed mode, the positioning of the second backrest frame (7) is maintained in a stable position thanks to the fact that the second arms (5b) are in contact with the first arms (5a) of the two articulated structures (5).
Asimismo, partiendo de la posicion desplegada en modo cama, para transformar al modo sofa, se empuja dicho larguero17 hacia el interior del mueble 1, donde con esta operacion se desplazara el primer bastidor 6 y tambien el segundo bastidor 7 hasta alcanzar la posicion de plegado en la que el primer bastidor 6 junto con el elemento de asiento 6a se mantienen en una posicion horizontal y el segundo bastidor 7 junto con el elemento de respaldo 7a de situan en una posicion sustancialmente vertical. Also, starting from the position deployed in bed mode, to transform to the sofa mode, said stringer 17 is pushed towards the interior of the cabinet 1, where with this operation the first frame 6 and also the second frame 7 will move until reaching the folding position wherein the first frame 6 together with the seat element 6a are held in a horizontal position and the second frame 7 together with the backing element 7a is placed in a substantially vertical position.
Durante las operaciones de plegado y desplegado para alcanzar el modo sofa o el modo cama mediante el sistema de conversion de la invention, los primeros elementos de conexion 9 y los segundos elementos de conexion 10 de las dos estructuras articuladas 5 se desplazan guiados en todo momento a lo largo de las guias inferiores 2 y superiores 3; donde los primeros brazos 5a se mueven en direcciones paralelas a lo largo de las guias inferiores 2, mientras que los segundos brazos 5b son arrastrados por los primeros brazos 5a, a la vez que dichos segundos brazos 5b basculan alrededor de la articulation comun 8 variando sus posiciones relativas con respecto a los primeros brazos 5a.During the folding and unfolding operations to reach the sofa mode or the bed mode by means of the conversion system of the invention, the first connecting elements 9 and the second connecting elements 10 of the two articulated structures 5 move guided at all times along the lower guides 2 and upper 3; where the first arms 5a move in parallel directions along the lower guides 2, while the second arms 5b are dragged by the first arms 5a, while said second arms 5b swing around the joint articulation 8 varying their relative positions with respect to the first arms 5a.
Durante las operaciones de plegado y desplegado, el segundo bastidor 7 de respaldo se mantiene en una position sustancialmente vertical mientras los segundos elementos de conexion 10 de los segundos brazos 5b estan situados a lo largo de los tramos rectos 3a de las guias superiores 3.During the folding and unfolding operations, the second backrest frame 7 is held in a substantially vertical position while the second connection elements 10 of the second arms 5b are located along the straight sections 3a of the upper guides 3.
En cambio, cuando dichos segundos elementos de conexion 10 de los segundos brazos 5b alcanzan los tramos arqueados 3b de las guias superiores 3, varia progresivamente la inclination del segundo bastidor 7 de respaldo; todo ello segun se muestra en las figuras 4a a 4c, de forma que cuando los segundos elementos de conexion 10 alcanzan unos extremos de dichos tramos arqueados 3b de las guias superiores 3, el segundo bastidor 7 de respaldo se coloca en la posicion horizontal.On the other hand, when said second connection elements 10 of the second arms 5b reach the arched sections 3b of the upper guides 3, the inclination of the second backrest frame 7 progressively varies; all of this as shown in figures 4a to 4c, so that when the second connection elements 10 reach ends of said arched sections 3b of the upper guides 3, the second backrest frame 7 is placed in the horizontal position.
Durante dichas operaciones de plegado y desplegado varia la distancia entre la primera articulacion 12 y la segunda articulacion 13 de cada accionador 11.During said folding and unfolding operations, the distance between the first articulation 12 and the second articulation 13 of each actuator 11 varies.
Gracias a los dos accionadores 11 se realiza un esfuerzo mmimo en la transformation de sofa a cama y viceversa, en el que tambien participan las guias inferiores 2 y superiores 3, asi como las guias laterales 14, de manera que los dos accionadores 11 ayudan en el movimiento de los dos bastidores 6, 7 reduciendo el esfuerzo necesario a aplicar.Thanks to the two actuators 11, a minimal effort is made in the transformation from sofa to bed and vice versa, in which the lower guides 2 and upper 3 also participate, as well as the lateral guides 14, so that the two actuators 11 help in the movement of the two frames 6, 7 reducing the effort necessary to apply.
Ademas cabe senalar que durante las operaciones de plegado y desplegado el bastidor inferior 6 esta guiado en todo momento en las guias laterales 14 y tambien se encuentra guiado por los primeros brazos 5a a lo largo de las guias inferiores 2.It should also be noted that during the folding and unfolding operations the lower frame 6 is guided at all times in the lateral guides 14 and is also guided by the first arms 5a along the lower guides 2.
Asi pues, gracias a la configuration y disposition del sistema de conversion de la invencion, para pasar del modo sofa al modo cama se consigue tirando del larguero17 hacia fuera del mueble 1, donde con esta operacion se transforma el modo sofa del mueble 1 en modo cama; mientras que para pasar del modo cama al modo sofa, se empuja hacia adentro del mueble 1 sobre el larguero17, de forma que el modo cama vuelve a su posicion original de sofa; destacandose que no es necesario levantar manualmente el conjunto del segundo bastidor 7 y el elemento de respaldo 7a.So, thanks to the configuration and disposition of the conversion system of the invention, to move from sofa to bed mode is achieved by pulling the stringer17 out of the furniture 1, where with this operation the sofa mode of furniture 1 is transformed into bed mode; while to move from the bed mode to the sofa mode, it is pushed into the furniture 1 on the stringer 17, so that the bed mode returns to its original sofa position; it being emphasized that it is not necessary to manually lift the assembly of the second frame 7 and the backing element 7a.
Se destaca que no se emplea ningun espacio de la zona inferior del mueble 1 por debajo de las guias laterales 14, lo cual lo convierte en especialmente ventajoso para el almacenamiento de objetos; incluso se pueden montar unos cajones 18 para poder guardar dichos objetos.It is emphasized that no space is used in the lower area of the furniture 1 below the lateral guides 14, which makes it especially advantageous for the storage of objects; even drawers 18 can be mounted to store said objects.
Se destaca tambien la ventaja de que el mueble puede estar situado en una zona adyacente a una pared, de forma que no habria problema a la hora de la conversion de sofa en cama, no siendo necesario separar el mueble con respecto a dicha pared, ya que el abatimiento del conjunto del segundo bastidor 7 y respaldo 7a se realiza junto con un desplazamiento de avance hacia el frontal del mueble 1 donde se encuentra el larguero 17. It also highlights the advantage that the furniture can be located in an area adjacent to a wall, so that there would be no problem when converting sofa into bed, it is not necessary to separate the furniture with respect to said wall, since that the folding of the assembly of the second frame 7 and backrest 7a is carried out together with a forward movement towards the front of the piece of furniture 1 where the stringer 17 is located.
