El presente invento se refiere a una pieza convertible de mobiliario que puede convertirse de un sofá y/o una cama individual a una litera.The present invention relates to a piece convertible furniture that can be converted from a sofa and / or a Single bed to a bunk bed.

Existe la necesidad constante de optimizar el uso del espacio disponible cuando se amuebla una habitación. Consiguientemente, con frecuencia se prefieren, y algunas veces resulta esencial utilizar, piezas de mobiliario que cumplan múltiples funciones. Esta necesidad resulta primordial, por ejemplo, en el caso de habitaciones para niños, en las que el espacio es verdaderamente esencial, o en el caso de hostales u hoteles, cuando la necesidad de ofrecer una habitación con un sofá que sea cómodo y estéticamente agradable se combina con la de disponer del máximo número de camas.There is a constant need to optimize use of the space available when a room is furnished. Consequently, they are often preferred, and sometimes it is essential to use, pieces of furniture that comply multiple functions This need is paramount, for example, in the case of rooms for children, in which the space is truly essential, or in the case of hostels or hotels, when the need to offer a room with a sofa that is comfortable and aesthetically pleasing is combined with having the maximum number of beds

En el transcurso del tiempo se han propuesto muchas soluciones para satisfacer las anteriores necesidades y existen gran número de sofás que se convierten en camas, literas o camas individuales con una cuna para emergencias.In the course of time they have been proposed many solutions to meet the above needs and there are a large number of sofas that convert into beds, bunk beds or Single beds with an emergency cot.

La técnica anterior incluye varios sofás que pueden convertirse en una cama y otros que pueden convertirse en dos camas en el espacio de una, pero estos sofás de la técnica anterior difícilmente pueden cumplir todas las funciones adecuadamente.The prior art includes several sofas that they can become a bed and others that can become two beds in the space of one, but these technical sofas previous can hardly fulfill all the functions adequately.

Otro inconveniente de la técnica anterior es que los sofás, cuando se convierten en camas, con frecuencia resultan cómodos como sofá o como cama, pero no como ambos a la vez.Another drawback of the prior art is that sofas, when they become beds, often result comfortable as a sofa or as a bed, but not as both at the same time.

Otro inconveniente de la técnica anterior es que si se extrae una cama situada bajo el sofá o bajo otra cama, para utilizarla, ocupa el espacio de otra cama sin satisfacer la necesidad de optimizar el espacio.Another drawback of the prior art is that if a bed located under the sofa or under another bed is removed, to use it, occupies the space of another bed without satisfying the Need to optimize space.

Otro inconveniente de la técnica anterior es que la segunda cama, incluso cuando se utiliza debajo de la cama individual elevada, no puede ser considerada como una verdadera litera, ya que el espacio entre ambas camas no es suficiente para considerarlas como tal y la segunda cama, en cualquier caso, se encuentra a una altura considerablemente más baja que una cama normal.Another drawback of the prior art is that the second bed, even when used under the bed individual high, can not be considered as a true bunk bed, since the space between both beds is not enough to consider them as such and the second bed, in any case, is found at a height considerably lower than a bed normal.

Otro inconveniente de la técnica anterior es que incluso cuando la segunda cama satisface la necesidad de optimizar el espacio, quedando situada debajo de la cama individual, no siempre cumple las máximas exigencias de seguridad, especialmente en lo que se refiere a su despliegue.Another drawback of the prior art is that even when the second bed satisfies the need to optimize the space, being located under the single bed, does not always meets the highest safety requirements, especially in regards to its deployment.

Un ejemplo de un sofá que puede convertirse en una litera puede encontrarse en la publicación "Product Licensing Index" núm. 177 (págs. 37-38).An example of a sofa that can become a bunk can be found in the publication "Product Licensing Index "No. 177 (pp. 37-38).

Un miembro longitudinal 7, hecho preferiblemente de tubo metálico, está roscado entre las patillas y actúa como soporte para los componentes de acolchado del respaldo 54.Pins 6, preferably made of sheet metal, are provided in frame halves 1, in a region rear A longitudinal member 7, preferably made of tube metallic, it is threaded between the pins and acts as a support for the padding components of the backrest 54.

Un segundo par de mitades de bastidor 9, simétricas e idénticas a las mitades de bastidor 1, están dispuestas en una región frontal y están conectadas a las mitades de bastidor 1 mediante la dos bisagras 10 que están acopladas rígidamente, por ejemplo por soldadura, a las mitades de bastidor 1 y 9.A second pair of frame halves 9, symmetrical and identical to frame halves 1, are arranged in a frontal region and connected to the halves of frame 1 by means of the two hinges 10 that are coupled rigidly, for example by welding, to frame halves 1 and 9.

Un somier 15 está dispuesto dentro de las mitades de bastidor 1 y descansa sobre los miembros longitudinales 3 y 5 y sobre los soportes ajustables 16 acoplados rígidamente al somier 11. Ménsulas 17 están acopladas rígidamente al somier 15 en una región trasera, por ejemplo por soldadura, y están articuladas al par de pivotes 18 acoplados rígidamente a las mitades de bastidor 1. Ventajosamente, en su lado trasero, el somier 15 tiene un marco 19 de retención de colchón, hecho de tubo metálico conformado.A bed base 15 is arranged inside the halves of frame 1 and rests on the longitudinal members 3 and 5 and on adjustable supports 16 rigidly coupled to the bed base 11. Corbels 17 are rigidly coupled to bed base 15 in a rear region, for example by welding, and are articulated to the pair of pivots 18 rigidly coupled to frame halves 1. Advantageously, on its rear side, the bed base 15 has a frame 19 of mattress retention, made of shaped metal tube.

En el lado opuesto con respecto al panel 14 de recubrimiento, una escalera plegable 60, constituida por un paralelogramo deformable, está articulada al somier 11 que está acoplado rígidamente a las mitades de bastidor 9 y está dispuesta por debajo del somier 15 de forma que la superficie de soporte esté dirigida hacia abajo.On the opposite side with respect to panel 14 of covering, a folding ladder 60, consisting of a deformable parallelogram, is articulated to the bed base 11 which is rigidly coupled to the frame halves 9 and is arranged below the bed base 15 so that the support surface is directed down.

Como se muestra de la mejor manera en la Fig. 3, la escalera 60 comprende un montante corto 20, un montante largo 21, tres peldaños 22, 23 y 24, una barrera de seguridad 25 y una barra para la barrera 26. Los peldaños 22, 23 y 24 están articulados a los montantes 20 y 21 en torno a los pivotes 27, 28, 29, 30, 31 y 32.As shown in the best way in Fig. 3, the ladder 60 comprises a short upright 20, a long upright 21, three steps 22, 23 and 24, a safety barrier 25 and a barrier bar 26. Steps 22, 23 and 24 are articulated to the uprights 20 and 21 around the pivots 27, 28, 29, 30, 31 and 32.

La barrera 25 está articulada al montante 21 alrededor del pivote 33 y a la barra 26 alrededor del pivote 34, mientras que, en su otro extremo, la barra 26 está articulada al somier 11 en torno al pivote 35.The barrier 25 is articulated to the post 21 around pivot 33 and to bar 26 around pivot 34, while, at its other end, the bar 26 is articulated to the box spring 11 around pivot 35.

Los montantes 20 y 21 están pivotados en torno a los pivotes 36 y 37, que están acoplados rígidamente a las placas 38 y 39, que están soldadas al somier 11.The uprights 20 and 21 are pivoted around pivots 36 and 37, which are rigidly coupled to the plates 38 and 39, which are welded to the bed base 11.

La unidad 41 de muelle/amortiguador está articulada a la placa 39 en torno al pivote 40 y está articulada por u otro extremo en torno al pivote 42, que está acoplado rígidamente al montante 21.The spring / shock absorber unit 41 is articulated to plate 39 around pivot 40 and is articulated by or other end around pivot 42, which is coupled rigidly to the stud 21.

Empujando ligeramente los montantes 20 y 21 de la escalera 60 como se ha descrito, ésta gira en sentido contrario al de las agujas del reloj en torno a los pivotes 36 y 37, de forma que el sistema constituido por la escalera y la barrera y constituido por paralelogramos deformables, se dispone horizontalmente por sí mismo, sostenido por la unidad 41 de muelle/amortiguador, variando sus dimensiones hasta que se pliega completamente hacia arriba y en posición horizontal.Slightly pushing uprights 20 and 21 of the staircase 60 as described, it turns counterclockwise clockwise around pivots 36 and 37, so that the system constituted by the ladder and the barrier and consisting of deformable parallelograms, it is arranged horizontally by itself, held by unit 41 of spring / shock absorber, varying its dimensions until it folds completely up and in a horizontal position.

El montante 21, que es coaxial con la barra 26, sólo puede llegar al final de su carrera después de haber sido forzado manualmente a superponerse sobre la barra 26, produciendo así un efecto elástico que ayuda a mantener al sistema en la posición horizontal (en la Figura 3, la posición plegada de la escalera 60 y de la barrera se ilustra en línea de trazos).The stile 21, which is coaxial with the bar 26, You can only reach the end of your career after being manually forced to overlap on bar 26, producing thus an elastic effect that helps keep the system in the horizontal position (in Figure 3, the folded position of the staircase 60 and the barrier is illustrated in dashed line).

Una unidad 45 de muelle/amortiguador está articulada entre una de las mitades de bastidor 1 y el somier 15, en los puntos 43 y 44, y facilita el giro excesivo parcial del somier 15 y del correspondiente colchón 46, requerido para extracción subsiguiente, por rotación, del segundo somier 15 y del correspondiente colchón 47.A spring / shock absorber unit 45 is articulated between one of the frame halves 1 and the bed base 15, at points 43 and 44, and facilitates partial excessive rotation of the box spring 15 and the corresponding mattress 46, required for subsequent extraction, by rotation, of the second bed base 15 and the corresponding mattress 47.

La unidad 48 de muelle/amortiguador está articulada en torno al pivote 49, que está acoplado rígidamente a la patilla 50, que está soldada dentro del miembro de perfil metálico en U 8 y, en su otro extremo, en torno al pivote 51, que está acoplado rígidamente a la patilla 52 soldada dentro del miembro de perfil metálico en U 53, de forma que, en la posición cerrada, como el pivote 51 está axialmente desplazado con respecto a la articulación 49 y a la bisagra 10, mantiene el par de bastidores 1 y 9, mutuamente abisagrados, en una posición cerrada, estable.The spring / shock absorber unit 48 is articulated around pivot 49, which is rigidly coupled to pin 50, which is welded inside the profile member metallic at U 8 and, at its other end, around pivot 51, which is rigidly coupled to pin 52 welded inside the member U-shaped metal profile 53, so that, in the closed position, as the pivot 51 is axially offset with respect to the joint 49 and hinge 10, maintains the pair of racks 1 and 9, mutually hinged, in a closed, stable position.

La unidad 48 de muelle/amortiguador está dispuesta, por tanto, durante su compresión máxima, dentro del par de miembros de perfil en U 8 y 53, que la ocultan de la vista cuando la pieza de mobiliario está cerrada.The spring / shock absorber unit 48 is arranged, therefore, during maximum compression, within the torque of U 8 and 53 profile members, who hide it from view when the piece of furniture is closed.

Con el fin de convertir la pieza de mobiliario desde una posición de sofá (en la que el colchón 46 actúa como asiento, el colchón 47 está almacenado boca abajo debajo del colchón precedente y el acolchado del respaldo 54 está soportado por el miembro longitudinal 7) a una posición de cama individual, basta con retirar el acolchado 54 de respaldo, mientras que la conversión en litera supone (véase la Fig. 2) voltear parcialmente el somier 15 y el correspondiente colchón 46, que son empujados y soportados por la unidad 45 de muelle/amortiguador y, luego, agarrando el panel 14 de recubrimiento, empujar hacia arriba, de forma que el sistema compuesto por el par de bastidores 9, los miembros longitudinales correspondientes 12 y 13, el colchón 47, la escalera 60 y el conjunto de barrera abisagrado al par de bastidores 11, en virtud del par de bisagras 10, gira en 180º, ayudado y soportado por el empuje de la unidad 48 de muelle/amortiguador, disponiéndose por sí mismo en la configuración de litera (Fig. 2).In order to convert the piece of furniture from a sofa position (in which the mattress 46 acts as seat, mattress 47 is stored upside down under the preceding mattress and backrest padding 54 is supported by longitudinal member 7) to a single bed position, just remove the back pad 54 while the bunk conversion assumes (see Fig. 2) partially flip the bed base 15 and the corresponding mattress 46, which are pushed and supported by the spring / shock absorber unit 45 and then grabbing the cover panel 14, push up, of so that the system composed of the pair of racks 9, the corresponding longitudinal members 12 and 13, mattress 47, the ladder 60 and the hinged barrier assembly next to Racks 11, by virtue of the pair of hinges 10, rotates 180º, helped and supported by the thrust of unit 48 of spring / shock absorber, disposing itself in the configuration bunk bed (Fig. 2).

Los componentes de acolchado del respaldo 54 pueden guardarse en la superficie de soporte 55. El somier 15 y el correspondiente colchón 46 vuelven a posicionarse horizontalmente y son soportados por los miembros longitudinales 3 y 5, mientras que la segunda cama queda accesible después de hacer girar, en 90º, la escalera y la barrera correspondiente, que están plegadas frontal y horizontalmente, agarrando, por ejemplo el montante 21 y haciéndolo girar en el sentido de las agujas del reloj, con ayuda de la unidad 41 de muelle/amortiguador, que cumple una función de contrapeso, hasta que la escalera es desplegada verticalmente y la barrera, simultáneamente, se levanta. Esta operación abre la cadena de paralelogramos que constituye el conjunto escalera-barrera.The padding components of the backrest 54 can be stored on the support surface 55. The bed base 15 and the corresponding mattress 46 reposition horizontally and they are supported by longitudinal members 3 and 5, while the second bed is accessible after turning, in 90º, the ladder and the corresponding barrier, which are folded front and horizontally, grabbing, for example, the stud 21 and making it turn clockwise, with the help of the unit 41 spring / shock absorber, which performs a counterweight function, until the ladder is deployed vertically and the barrier, simultaneously, it rises. This operation opens the chain of parallelograms that constitutes the set barrier ladder

Con el fin de volver a la posición original, basta con realizar las operaciones a la inversa, después de anclar el colchón 47 al somier 11 mediante un par de cintas 56 previstas a tal fin, mientras que con el fin de facilitar el fácil acceso a la cama superior, basta con plegar la escalera hacia arriba, a la posición horizontal y hacer girar hacia abajo a la parte móvil de la unida de mobiliario hasta que la fuerza de la unidad 48 de muelle/amortiguador equilibre el peso; esto ocurre, aproximadamente, después de un cuarto de vuelta. El colchón es inclinado así hacia delante, con lo que se facilita el preparar la cama.In order to return to the original position, just perform the operations in reverse, after anchoring the mattress 47 to the bed base 11 by means of a pair of tapes 56 provided to such purpose, while in order to facilitate easy access to the upper bed, just fold the ladder up, to the horizontal position and turn down the moving part of the united furniture until the strength of unit 48 of spring / damper balance weight; this happens, approximately, after a quarter turn. The mattress is inclined thus forward, which makes it easier to prepare the bed.

En la práctica se ha visto como se han conseguido, de acuerdo con el presente invento, los objetivos y los fines antes mencionados mediante una pieza de mobiliario que se convierte, por rotación, de sofá y/o cama individual, en litera, cuyo invento incluye: un par de bastidores metálicos verticales que están rígidamente acoplados a un par de barras horizontales que cumplen una función de soporte y están conectadas mutuamente por cuatro miembros longitudinales horizontales; un somier, que está abisagrado dentro de los bastidores y que, también, actúa como soporte para el asiento; un segundo par de miembros metálicos verticales, que son simétricos y están dispuestos en una posición avanzada con respecto al primer par y que están conectados por dos miembros longitudinales horizontales; un marco de tubo metálico que está acoplado rígidamente al par de bastidores y que actúa como somier para el segundo colchón; una escalera, que constituye un paralelogramo deformable, que tiene una barrera asociada y que está articulada al somier de la segunda cama. Los pares de bastidores están mutuamente abisagrados en el frente y en la región superior, de manera que después de dar la vuelta parcialmente al somier de la primera cama, con ayuda del empuje de una unidad de muelle/amortiguador, y haciendo girar en 180º al par de bastidores frontales y al somier que está rígidamente acoplado a ellos con ayuda de otra unidad de muelle/amortiguador, el somier y el colchón correspondiente que estaban dispuestos boca abajo debajo de la superficie de la primera cama, quedan dispuestos ahora adecuadamente por encima de la superficie y en la posición de uso como litera, soportados de forma estable por el par de bastidores gemelos subyacentes. La escalera y la barrera correspondiente, a continuación de la rotación de la segunda cama, son plegadas horizontalmente en posición frontal. En virtud de la simple rotación de un montante, la escalera, al girar en dos pivotes que están rígidamente acoplados al somier, se despliega y se abre con el fin de quedar dispuesta en posición vertical para soportar el somier, al tiempo que la barrera, que está articulada a la escalera, sube. Se obtiene así la conversión en litera sin esfuerzo y con un pequeño número de movimientos sencillos y seguros. Realizando estas operaciones a la inversa, la pieza de mobiliario puede disponerse de nuevo en la posición plegada, o cerrada, actuando como cama individual que es un cómodo sofá, equipada con almohadones previstos a tal fin, soportados por uno de los miembros longitudinales de la primera cama. Los almohadones o cojines pueden guardarse debajo de la primera cama cuando la unidad de mobiliario se utiliza como litera.In practice it has been seen how they have achieved, in accordance with the present invention, the objectives and the purposes mentioned above through a piece of furniture that converts, by rotation, from sofa and / or single bed, to bunk, whose invention includes: a pair of vertical metal racks that are rigidly coupled to a pair of horizontal bars that they fulfill a support function and are mutually connected by four horizontal longitudinal members; a box spring, which is hinged inside the racks and that also acts as seat support; a second pair of metal members vertical, which are symmetrical and are arranged in a position advanced with respect to the first pair and they are connected by two horizontal longitudinal members; a metal tube frame that is rigidly coupled to the pair of racks and acts as box spring for the second mattress; a ladder, which constitutes a deformable parallelogram, which has an associated barrier and which is articulated to the bed base of the second bed. The pairs of racks they are mutually hinged in the front and in the upper region, so that after partially turning the bed base of the first bed, with the help of the thrust of a unit of spring / shock absorber, and turning the pair of frames 180º front and box spring that is rigidly coupled to them with support of another spring / shock absorber unit, box spring and mattress corresponding that they were arranged upside down under the surface of the first bed, are now properly disposed above the surface and in the position of use as a berth, stably supported by the pair of twin racks underlying. The ladder and the corresponding barrier, to continuation of the rotation of the second bed, are folded horizontally in front position. Under the simple rotation of an upright, the ladder, when turning on two pivots that are rigidly coupled to the bed base, unfolds and opens in order of being arranged in an upright position to support the bed base, when time that the barrier, which is articulated to the stairs, goes up. I know get the conversion into berth effortlessly and with a small number of simple and safe movements. Performing these operations in reverse, the piece of furniture can be arranged new in the folded position, or closed, acting as a bed individual that is a comfortable sofa, equipped with pillows provided for that purpose, supported by one of the members Longitudinal of the first bed.
