Description

Mecanismo para el despliegue y repliegue de un elemento cama de sofá-cama Mechanism for the deployment and folding of a sofa bed element

TECHNICAL FIELD OF THE INVENTION

La presente invención, según se indica en el título de esta memoria descriptiva, se refiere a un mecanismo para el despliegue hasta la posición de cama de un elemento cama de sofá-cama y su correspondiente repliegue hasta la posición de sofá. The present invention, as indicated in the title of this specification, refers to a mechanism for the deployment to the bed position of a sofa bed bed element and its corresponding folding to the sofa position.

BACKGROUND OF THE INVENTION

Son conocidos en el sector del mobiliario los sofá-cama que permiten realizar las operaciones de despliegue y repliegue del elemento cama sin necesidad de retirar los cojines que conforman la superficie de asiento ni los que conforman la superficie de respaldo, como se puede observar en el documento modelo de utilidad español ES1047164U en el que, sin detallar el mecanismo, se describe una solución para dicho problema. In the furniture sector, the sofa beds that allow the operations of unfolding and folding the bed element without the need to remove the cushions that make up the seating surface or those that make up the backing surface, as can be seen in the furniture sector, are known Spanish utility model document ES1047164U in which, without detailing the mechanism, a solution to this problem is described.

Sin embargo, las soluciones conocidas aún no han conseguido resultar absolutamente sencillas y cómodas para el usuario de cara al despliegue y repliegue del elemento cama. Son múltiples las ocasiones en las que la altura alcanzada por el extremo inferior del elemento cama en su posición intermedia de despliegue dificulta dicha operación para las personas de estatura media, que usualmente tienen que recurrir a operar sobre el elemento cama por un lateral del mismo, cuando esto es posible, resultando en un desequilibrio de esfuerzos en el mecanismo de despliegue entre sus partes laterales izquierda y derecha. However, the known solutions have not yet been absolutely simple and comfortable for the user for the deployment and folding of the bed element. There are multiple occasions in which the height reached by the lower end of the bed element in its intermediate deployment position makes said operation difficult for people of medium height, who usually have to resort to operating on the bed element on one side thereof, when this is possible, resulting in an imbalance of efforts in the deployment mechanism between its left and right side parts.

Igualmente, y relacionado con lo anterior, la operación de repliegue del elemento cama resulta incómoda y difícil para personas de estatura media, puesto que se ha de realizar una fuerza descendente sobre el extremo inferior del elemento cama, el cual, en posición cercana al repliegue, se encuentra dispuesto a una distancia considerable del usuario que suele optar por ejercer la presión sobre una zona más cercana, sobrecargando de ese modo el mecanismo de repliegue y llegando, en casos extremos, a la rotura de los elementos constituyentes de dicho mecanismo. Likewise, and related to the above, the operation of folding the bed element is uncomfortable and difficult for people of medium height, since a downward force has to be made on the lower end of the bed element, which, in a position close to the fold , it is arranged at a considerable distance from the user who usually chooses to exert pressure on a closer area, thereby overloading the folding mechanism and reaching, in extreme cases, the breakage of the constituent elements of said mechanism.

Es por tanto objeto de la presente invención un mecanismo de despliegue y repliegue de sofá-cama que permita, aparte de realizar dichas operaciones sin necesidad de retirar los cojines, realizar el despliegue de manera fácil y cómoda sin tener que recurrir el usuario a ejercer fuerza por uno de los laterales del elemento cama y a su vez permita que el repliegue se realice de manera semi-automática una vez alcanzado un punto concreto en la operación de repliegue, de modo que el usuario no tenga que realizar una fuerza descendente sobre el extremo inferior del elemento cama. It is therefore an object of the present invention a mechanism for unfolding and folding the sofa bed that allows, apart from performing said operations without the need to remove the cushions, to carry out the deployment in an easy and comfortable way without having to resort to the user to exert force on one of the sides of the bed element and in turn allow the folding to be carried out semi-automatically once a specific point has been reached in the folding operation, so that the user does not have to make a downward force on the lower end of the bed element.

DESCRIPTION OF THE INVENTION

La presente invención se refiere a un mecanismo para el despliegue y repliegue del elemento cama de un sofá-cama que está comprendido por cuatro semiestructuras rígidas que conforman el elemento cama, una semiestructura rígida que conforma la base, una semiestructura rígida que conforma el respaldo del sofá en posición replegada del mecanismo, cuatro muelles de retroceso y doce barras articuladas. The present invention relates to a mechanism for the deployment and folding of the bed element of a sofa bed that is comprised of four rigid semi-structures that make up the bed element, a rigid semi-structure that forms the base, a rigid semi-structure that forms the backrest of the sofa in position retracted from the mechanism, four recoil springs and twelve articulated bars.

Las cuatro semiestructuras rígidas están articuladas entre sí de modo directo y, en posición desplegada, conforman una superficie horizontal paralela al suelo y a la semiestructura rígida que conforma la base. The four rigid semi-structures are articulated with each other directly and, in an unfolded position, form a horizontal surface parallel to the ground and the rigid semi-structure that forms the base.

Las articulaciones, tanto para las cuatro semiestructuras rígidas mencionadas como las que se mencionan en adelante en el presente documento, únicamente permiten el giro entre los elemento que unen. The joints, both for the four rigid semi-structures mentioned and those mentioned hereinafter, only allow rotation between the elements that join.

La semiestructura rígida que conforma el respaldo del sofá en posición replegada es la encargada de, en posición desplegada, mantener tanto los cojines que conforman la superficie de asiento como los que conforman la superficie de respaldo en la zona inferior del elemento cama, de modo que no es necesario retirarlos al realizar la operación de despliegue ni la de repliegue. The rigid semi-structure that forms the backrest of the sofa in a folded position is responsible for, in the deployed position, keeping both the cushions that make up the seating surface and those that make up the backing surface in the lower area of the bed element, so that It is not necessary to remove them when performing the deployment operation or the withdrawal operation.

Los cuatro muelles de retroceso están encargados, una vez superado un punto concreto en la operación de repliegue, usualmente a partir de que el extremo inferior del elemento cama haya alcanzado su altura máxima, de continuar de manera semi-automática dicha operación de repliegue, evitándole al usuario la necesidad de realizar una fuerza descendente sobre el extremo inferior del elemento cama. The four recoil springs are in charge, once a specific point in the folding operation has been exceeded, usually after the lower end of the bed element has reached its maximum height, to continue said folding operation semi-automatically, avoiding to the user the need to make a downward force on the lower end of the bed element.

Las doce barras articuladas se disponen de modo que relacionan todos los elementos anteriores, consiguiendo que las operaciones de despliegue y repliegue sean sencillas y cómodas y que el extremo inferior del elemento cama no alcance una altura elevada durante la operación de despliegue, evitando de este modo una de las problemáticas del estado de la técnica conocido. The twelve articulated bars are arranged so that they relate all the previous elements, making the deployment and folding operations simple and comfortable and that the lower end of the bed element does not reach a high height during the deployment operation, thus avoiding one of the problems of the known state of the art.
