Más concretamente, en la invención se ha ideado un dispositivo electromecánico especialmente destinado para su aplicación en pequeños muebles de tipo auxiliar, tales como cabeceros, detrás del sofá, recibidores, muebles bar, lateral/frontal escritorios, almacenaje en pasillos, separador ambientes, salas reuniones, expositores comercios, mesas de televisión, etc., concebido para ganar espacio y almacenaje, facultar la elevación de dichos muebles o partes de los mismos, desde una posición o nivel inferior inoperante y opcionalmente oculta, hasta una posición o nivel elevado y funcional. or parts thereof. More specifically, in the invention an electromechanical device specially designed for application in small auxiliary furniture has been devised, such as headboards, behind the sofa, hallways, bar furniture, side / front desks, aisle storage, room divider, rooms meetings, commercial exhibitors, television tables, etc., designed to gain space and storage, empower such furniture or parts thereof, from an inoperative and optionally hidden lower position or level, to a high and functional position or level .

BACKGROUND OF THE INVENTION

Existen en la actualidad diversos sistemas elevadores de superficie de descanso de canapés y muebles similares, particularmente divanes y camas, que permite que dicha superficie de descanso pueda adoptar dos posiciones diferentes: una posición bajada en la que el usuario puede reposar sobre dicha superficie de descanso y una posición elevada en la que es posible acondicionar dicha superficie, por ejemplo cambiando sábanas o realizando otras labores similares para hacer la cama, a una altura que no requiere que el usuario tenga que inclinarse demasiado y, en consecuencia, adoptar una postura forzada incómoda. There are currently several lifting systems for resting surfaces of canapés and similar furniture, particularly couches and beds, which allows said resting surface to adopt two different positions: a lowered position in which the user can rest on said resting surface and an elevated position in which it is possible to condition said surface, for example by changing sheets or doing other similar tasks to make the bed, at a height that does not require the user to have to lean too much and, consequently, adopt an uncomfortable forced posture .

Se conocen ya camas y somieres dotados de medios para variar la altura de las superficies de descanso de los mismos con miras a facilitar las labores que hayan de realizarse en ellas. Estos medios suelen consistir en la combinación de bielas, muelles y/o pistones de gas instalados en un bastidor fijo del somier o de la cama. There are already known beds and bed bases equipped with means to vary the height of their rest surfaces with a view to facilitating the work to be done on them. These means usually consist of the combination of connecting rods, springs and / or gas pistons installed in a fixed bed frame or bed frame.

Este tipo de camas y somieres es requerido especialmente por los centros en los que han de hacerse cada día un gran número de camas. Ejemplos de estos centros son residencias, hospitales y hoteles, en donde es importante que el personal que realiza esta tarea no se vea obligado a adoptar reiteradamente posturas que violentan su espalda y pueden ser causa de lesiones. En los hogares tenemos canapés y sillones descanso y sofás cama. This type of beds and bed bases is especially required by the centers where a large number of beds are to be made every day. Examples of these centers are residences, hospitals and hotels, where it is important that the personnel performing this task are not forced to repeatedly adopt positions that violate their backs and can cause injuries. In the homes we have canapés and armchairs rest and sofa beds.

También es conocido el uso de amortiguadores para parte de muebles móviles en diferentes configuraciones con fluidos viscosos, amortiguadores por aire. Como se aprecia en los documentos JP0060272446, EP0430797, EP0841452 así como el DE4409716. It is also known to use dampers for part of mobile furniture in different configurations with viscous fluids, air dampers. As can be seen in documents JP0060272446, EP0430797, EP0841452 as well as DE4409716.
