Abstract

A lifting mechanism for the bedspring or the bed-plane (20) of an articulated bed is presented. The bedspring or the bed-plane (20) is connected to a chassis (10) laid on the ground, and comprises (i) a first and a second lifting arm (30, 40) mounted substantially parallel to each other and hinged to the chassis and the bed-plane to form an articulated parallelogram, one of the two arms being extendable through two segments (42, 44) mounted telescopically into one another, and (ii) elastic means thrusting between the two segments to counter the weight of the bed-plane and to servo their lifting. The elastic means (50) are arranged inside one or both of said segments (42, 44).

Description

Cama articulada con mecanismo de elevación. Articulated bed with lifting mechanism.

La presente invención se refiere a una cama articulada con un mecanismo de elevación. The present invention relates to an articulated bed with a lifting mechanism.

Son conocidas las camas articuladas con mecanismos de elevación que permiten elevar y mantener el somier de la cama (o las tablillas) de la cama (es decir, el denominado plano de la cama) a una cierta altura por encima del suelo, permitiendo que un ama de casa vuelva a hacer la cama confortablemente sin agacharse y tener que acceder al espacio por debajo del somier. The articulated beds with lifting mechanisms are known that allow to raise and maintain the bed base (or the slats) of the bed (that is, the so-called bed plane) at a certain height above the ground, allowing a Housewife make the bed comfortably again without bending down and having to access the space below the bed base.

En el pasado, el solicitante ha patentado un mecanismo, colocado en dos ejemplares idénticos en dos lados opuestos del armazón/chasis de la cama fijados al suelo, constituidos por un primer y un segundo brazo de elevación montados sustancialmente paralelos entre sí y articulados al armazón y al plano de la cama para formar un paralelogramo articulado. Uno de los dos brazos está construido de manera extensible, esto es a través de dos segmentos montados telescópicamente uno en el interior del otro. Esto permite, una vez está elevado el plano de la cama, inclinar el plano de la cama con respecto a un plano horizontal, de modo que se facilite el arreglo de la cama. Para oponerse al peso del plano de la cama -plano -cama y para permitir la elevación del mismo, unos medios elásticos están dispuestos en empuje (generalmente resortes) en los dos segmentos. Un resorte de gas está colocado entre el otro brazo, el inextensible y el chasis, otra vez con la función de permitir la elevación del plano de la cama. Generalmente, el brazo extensible consiste en casquillos de sección transversal rectangular y los medios elásticos están colocados al lado de ellos, fuera. El empuje de los medios elásticos tiende a distorsionar el brazo extensible, aumentando la fricción de sus segmentos telescópicos y requiriendo una fuerza mayor para la elevación del plano de la cama. También, se debe utilizar una barra de torsión por debajo del plano de la cama para compensar el empuje de los medios elásticos, con un incremento del peso y de los costes. In the past, the applicant has patented a mechanism, placed in two identical specimens on two opposite sides of the bed frame / chassis fixed to the floor, consisting of a first and a second lifting arm mounted substantially parallel to each other and articulated to the frame and to the bed plane to form an articulated parallelogram. One of the two arms is built in an extensible manner, this is through two segments telescopically mounted inside each other. This allows, once the bed plane is raised, to tilt the bed plane with respect to a horizontal plane, so that the arrangement of the bed is facilitated. To oppose the weight of the plane of the bed-flat-bed and to allow its elevation, elastic means are arranged in thrust (generally springs) in the two segments. A gas spring is placed between the other arm, the inextensible and the chassis, again with the function of allowing the elevation of the bed plane. Generally, the extendable arm consists of bushes of rectangular cross-section and the elastic means are placed next to them, outside. The thrust of the elastic means tends to distort the extensible arm, increasing the friction of its telescopic segments and requiring a greater force for the elevation of the bed plane. Also, a torsion bar should be used below the bed plane to compensate for the thrust of the elastic means, with an increase in weight and costs.

Los mecanismos de elevación conocidos comprenden el documento EP 1 374 741, el cual describe una cama contenedora con medios para mover un armazón del colchón conectados a un cuerpo del contenedor. En cada pared lateral del cuerpo del contenedor, está prevista una barra lateral articulada a la pared lateral. En la barra lateral, están dispuestos diversos brazos para sostener articuladamente el armazón del colchón. Known lifting mechanisms comprise EP 1 374 741, which describes a container bed with means for moving a mattress frame connected to a container body. On each side wall of the container body, a side bar articulated to the side wall is provided. On the sidebar, various arms are arranged to articulately support the mattress frame.

La invención, por lo tanto, resuelve el problema de la simplificación de la estructura del mecanismo, al mismo tiempo mejorándolo y eliminando algunos inconvenientes. The invention, therefore, solves the problem of simplifying the structure of the mechanism, at the same time improving it and eliminating some inconveniences.

Estos problemas se resuelven mediante una cama articulada con un mecanismo de elevación para el somier o el plano de la cama como se reivindica en la reivindicación 1. These problems are solved by an articulated bed with a lifting mechanism for the bed base or the bed plane as claimed in claim 1.

De este modo el empuje de los medios elásticos se dirige y se descarga a lo largo de la dirección del movimiento de los segmentos telescópicos y no induce a ningún esfuerzo lateral que tienda a curvarlos uno sobre el otro. Esto resulta en un deslizamiento mutuo mejorado en los segmentos telescópicos porque la fricción es inferior y la posibilidad de eliminación de la barra de torsión. Una construcción preferida permite que dichos segmentos tengan una sección transversal circular, circunstancia que permite mejorar el deslizamiento de los mismos y evita oscilaciones de los mismos puesto que se reducen los juegos mecánicos. Para dichos segmentos muy fácilmente se pueden utilizar casquillos de metal. Preferentemente, dichos medios elásticos comprenden un resorte de gas, un objeto muy fácilmente disponible y fiable. Preferentemente, el resorte de gas tiene su cuerpo montado en el interior de un segmento y su vástago conectado en acción de empuje al otro segmento, esto es el vástago está montado para empujar interiormente uno de los segmentos. Ventajas adicionales se pueden obtener cuando se utiliza un elemento montado entre dos segmentos adaptado para disminuir el coeficiente de fricción mutuo, por ejemplo un resorte, una junta o un collar, preferentemente formado a partir de material con un bajo coeficiente de fricción, por ejemplo Teflón®, aplicado coaxialmente por encima o en el interior del borde del segmento el cual contiene al otro. In this way the thrust of the elastic means is directed and discharged along the direction of the movement of the telescopic segments and does not induce any lateral effort that tends to bend them over each other. This results in an improved mutual sliding in the telescopic segments because the friction is lower and the possibility of torsion bar removal. A preferred construction allows said segments to have a circular cross-section, a circumstance that makes it possible to improve their sliding and prevents oscillations thereof since the mechanical games are reduced. For these segments, metal bushings can be used very easily. Preferably, said elastic means comprise a gas spring, a very easily available and reliable object. Preferably, the gas spring has its body mounted inside a segment and its rod connected in pushing action to the other segment, that is the rod is mounted to push one of the segments inside. Additional advantages can be obtained when using an element mounted between two segments adapted to decrease the coefficient of mutual friction, for example a spring, a joint or a collar, preferably formed from material with a low coefficient of friction, for example Teflon ®, coaxially applied above or inside the edge of the segment which contains the other.

Las ventajas de la invención se pondrán de manifiesto mediante la siguiente descripción de una forma de realización preferida, ilustrada en el dibujo adjunto que muestra un plano de la cama que se puede elevar con un mecanismo según la invención, en el cual: The advantages of the invention will be revealed by the following description of a preferred embodiment, illustrated in the attached drawing showing a bed plane that can be raised with a mechanism according to the invention, in which:

la figura 1 muestra una vista lateral del mecanismo según la invención en una posición cerrada; Figure 1 shows a side view of the mechanism according to the invention in a closed position;

la figura 2 muestra una vista lateral del mecanismo de la figura 1 en una posición elevada; Figure 2 shows a side view of the mechanism of Figure 1 in an elevated position;

la figura 3 muestra una vista lateral del mecanismo de la figura 1 en la posición elevada y con el plano de la cama inclinado; Figure 3 shows a side view of the mechanism of Figure 1 in the elevated position and with the plane of the inclined bed;

la figura 4 muestra una vista axonométrica del despiece del mecanismo de la figura 1. Figure 4 shows an axonometric view of the exploded view of the mechanism of Figure 1.

El mecanismo (o articulación) de la invención está montado en un armazón/chasis 10 fijado al suelo, el cual bajo las condiciones de reposo (plano de la cama no elevado) sirve como soporte a un plano de la cama o soporte para un somier de la cama 20. El chasis 10 actúa como una base para la cama (figura 1). Con una maniobra conocida, el plano de la cama 20 se puede elevar con respecto al chasis 10 (figura 2) y, cuando se eleva, puede ser oscilado con respecto a un plano horizontal (figura 3). Los movimientos permitidos al plano de la cama 20 son esencialmente conocidos (véanse también las flechas en las figuras 1 -3). The mechanism (or articulation) of the invention is mounted on a frame / chassis 10 fixed to the floor, which under the conditions of rest (bed plane not raised) serves as a support for a bed plane or support for a bed base of the bed 20. The chassis 10 acts as a base for the bed (figure 1). With a known maneuver, the plane of the bed 20 can be raised with respect to the chassis 10 (figure 2) and, when raised, it can be oscillated with respect to a horizontal plane (figure 3). The movements allowed to the plane of the bed 20 are essentially known (see also the arrows in Figures 1 -3).

El mecanismo que permite el movimiento del plano de la cama 20 está montado en dos ejemplares idénticos en dos lados de la cámara y comprende dos brazos rígidos 30, 40, cada uno giratoriamente articulado tanto al armazón 10 como al plano de la cama 20 mediante pasadores, indicados genéricamente con el número de referencia 12. El brazo 30 es de una sola pieza, mientras el brazo 40 tiene una estructura extensible telescópica y está formado por dos segmentos tubulares cilíndricos o casquillos huecos 42, 44. El segmento 44, por lo tanto, puede deslizarse en el interior del segmento 42. Los brazos 30, 40 están montados sustancialmente paralelos entre sí para formar un paralelogramo articulado con el cual elevar y sostener el plano de la cama 10. The mechanism that allows the movement of the bed plane 20 is mounted on two identical specimens on two sides of the chamber and comprises two rigid arms 30, 40, each rotatably articulated to both the frame 10 and the bed plane 20 by pins , indicated generically with the reference number 12. The arm 30 is in one piece, while the arm 40 has an extensible telescopic structure and is formed by two cylindrical tubular segments or hollow bushings 42, 44. The segment 44, therefore , can slide inside the segment 42. The arms 30, 40 are mounted substantially parallel to each other to form an articulated parallelogram with which to raise and support the bed plane 10.

Como resulta evidente a partir de la figura, para amortiguar los dos segmentos 42, 44 un resorte de gas 50 (véase la figura 4 en donde está representado esquemáticamente en una línea de trazos) está alojado en el interior del segmento 44, con su vástago 46 (véase la figura 3) interiormente conectado con, y en empuje sobre, el segmento As is evident from the figure, to dampen the two segments 42, 44 a gas spring 50 (see Figure 4 where it is schematically represented in a dashed line) is housed inside the segment 44, with its stem 46 (see figure 3) internally connected with, and in push on, the segment

42. Puesto que, entonces, el empuje del resorte 50 ocurre axialmente con respecto a los segmentos 42, 44 y no lateralmente, no soportan deformación o curvado lateral alguno (el momento de torsión del giro se elimina) y la estabilidad y la facilidad de un deslizamiento relativo resultan mejoradas. El resorte de gas 50, o cualquier medio equivalente, puede estar colocado en el interior de uno de los segmentos 42, 44 o en ambos, dependiendo de su tamaño o de las características deseadas para el mecanismo. 42. Since, then, the thrust of the spring 50 occurs axially with respect to the segments 42, 44 and not laterally, they do not support any deformation or lateral bending (the twisting moment of the rotation is eliminated) and the stability and ease of relative slippage are improved. The gas spring 50, or any equivalent means, can be placed inside one of the segments 42, 44 or both, depending on its size or the characteristics desired for the mechanism.

Aunque en las figuras está representada una barra de torsión conocida 60, adaptada para conectar y estabilizar los dos mecanismos de la cama, en la práctica ha probado ser innecesaria. Gracias a la sección circular de los segmentos 42, 44 su deslizamiento se presenta mejorado puesto que no existen bordes de deslizamiento sobre los cuales se puedan concentrar esfuerzos mecánicos. Para mejorar adicionalmente el deslizamiento de este tipo, se prefiere montar en la boca del segmento 42 un collar 62 (véase la figura 4), por ejemplo fabricado de Teflón®, a fin de mantener coaxiales y con un cierto juego mutuo (en el interior del segmento 42), así como para un mejor accionamiento, los dos segmentos 42, 44 evitando rozamientos indeseados. Although a known torsion bar 60 is shown in the figures, adapted to connect and stabilize the two bed mechanisms, in practice it has proved unnecessary. Thanks to the circular section of the segments 42, 44 its sliding is improved since there are no sliding edges on which mechanical stresses can be concentrated. To further improve the sliding of this type, it is preferred to mount a collar 62 in the mouth of segment 42 (see Figure 4), for example made of Teflon®, in order to keep coaxial and with a certain mutual play (inside of segment 42), as well as for a better drive, the two segments 42, 44 avoiding unwanted friction.

Un resorte de gas 70, articulado a través de pasadores 12 al armazón 10 y el brazo 30, completa el mecanismo. Su función es permitir la elevación del plano de la cama 10 y equilibrar el peso de la misma. A gas spring 70, articulated through pins 12 to the frame 10 and the arm 30, completes the mechanism. Its function is to allow the elevation of the bed plane 10 and balance its weight.
