Description of a preferred embodiment

Tal como se muestra en las figuras, una realización de la cama hospitalaria de la invención indicada de forma general con la referencia 1 comprende un bastidor inferior 2 provisto de patas de soporte 3 en cuatro esquinas y un bastidor superior 4 elevable con relación al bastidor inferior 2 por medios de elevación que se detallarán más adelante. Como puede verse en las figuras 1 y 2, tanto el bastidor superior 4 como inferior 2 están formados por un marco perimetral de planta rectangular que está preferentemente fabricado con material metálico que aportan una mayor rigidez al conjunto de la cama 1. Tales patas de soporte 3 están fijadas al bastidor inferior 2 mediante elementos de tornillería que presentan un cabezal con una forma geométrica específica acoplable de tal manera que cuando se montan las patas de soporte 3 no giran, asegurando así su correcto posicionamiento y fijación. Mencionar que será evidente para un experto en la materia que en vez de emplear patas de soporte 3 pueden montarse ruedas que proporcionen maniobrabilidad a la cama hospitalaria.As shown in the figures, a realization of the hospital bed of the indicated invention of general form with reference 1 comprises a lower frame 2 provided with support legs 3 in four corners and a frame upper 4 lift in relation to lower frame 2 by means elevation that will be detailed later. As can be seen in Figures 1 and 2, both upper frame 4 and lower 2 They are formed by a rectangular perimeter frame that It is preferably made of metallic material that provides greater rigidity to the bed assembly 1. Such support legs 3 are fixed to the lower frame 2 by means of screws that have a head with a geometric shape specific coupling so that when the legs are mounted of support 3 does not rotate, thus ensuring its correct positioning and fixation. Mention that it will be evident to an expert in the field that instead of using support legs 3 wheels can be mounted which provide maneuverability to the hospital bed.

Con referencia a dichos medios de elevación comprenden un par de juegos 5 enfrentados y ubicados en los dos laterales alargados de la cama. Tales juegos 5 están constituidos de dos varillas 6 articuladas cada una de ellas inferiormente al bastidor inferior 2 y superiormente al bastidor superior 4, las cuales están entrecruzadas y articuladas entre sí por un pasador 7 central, estando los extremos de cada varilla 6 guiadas para llevar a cabo un desplazamiento lineal cuando se realizan las operaciones de elevación o descenso del bastidor superior 4. Los dos juegos 5 mencionados están unidos transversalmente por medio de un travesaño de refuerzo 22 en forma de barra situado en la parte inferior que aporta mayor rigidez y estabilidad a los juegos 5.With reference to said lifting means they comprise a pair of 5 games facing and located in both elongated sides of the bed. Such games 5 are constituted of two rods 6 articulated each of them inferiorly to the lower frame 2 and superiorly to the upper frame 4, the which are intertwined and articulated with each other by a pin 7 central, the ends of each rod 6 being guided to carry perform a linear shift when operations are performed lifting or lowering the upper frame 4. The two sets 5 mentioned are linked transversely by means of a crossbar of reinforcement 22 in the form of a bar located at the bottom which brings greater rigidity and stability to the games 5.

Además, como puede verse en la figura 6, se proporciona un cilindro-pistón 8, del tipo hidráulico o eléctrico, accionado por medio de un motor de accionamiento eléctrico de tipo convencional, el cual está fijado de forma solidaria por un extremo al bastidor inferior 2 por medio de una barra transversal 24 de forma centrada mientras que el otro extremo del cilindro-pistón 8 está vinculado al bastidor superior 4 y está articulado a un travesaño 9, cuyo travesaño 9 está superiormente articulado al bastidor superior e inferiormente articulado al bastidor inferior 2 a través de dos perfiles 17, de manera que los dos perfiles 17 están relacionados en movimiento con el juego de varillas 5. Más en particular, el extremo del cilindro-pistón 8 está fijado a una prolongación saliente 14 de éste y con un pasador o elemento de sujeción 15 que sujeta el extremo del cilindro-pistón 8. Los perfiles 17 se deslizan en su parte superior a través de una ranura o guía horizontal provista en el bastidor superior 4. Dicho cilindro-pistón 8 actúa cuando se eleva y baja el bastidor superior 4 en la dirección indicada según las flechas representadas en la figura 6.In addition, as can be seen in Figure 6, it provides a piston cylinder 8, of the type hydraulic or electric, driven by means of a motor conventional electric drive, which is fixed in solidarity with one end to the lower frame 2 by means of a crossbar 24 centered while the other end of piston cylinder 8 is linked to upper frame 4 and is articulated to a crossbar 9, whose crossbar 9 is superiorly articulated to the upper frame and inferiorly articulated to the lower frame 2 through two profiles 17, so that the two profiles 17 are related moving with the set of rods 5. More particularly, the end of the piston-cylinder 8 is fixed to a protruding extension 14 thereof and with a pin or element of fastener 15 that holds the end of the piston-cylinder 8. The profiles 17 slide in its upper part through a groove or horizontal guide provided in the upper frame 4. Said piston cylinder 8 acts when the upper frame 4 is raised and lowered in the direction indicated according to the arrows represented in figure 6.

Cada uno de los perfiles 17 está articulado al bastidor inferior 2 por medio de un pasador alargado 23 de modo que realizan una trayectoria angular cuando sube y baja el bastidor superior 4. Es decir, la dirección y velocidad relativa de movimiento del travesaño 9 en el extremo superior es igual a la del extremo superior de la varilla 6 que se desliza, tal como se explicará con mayor detalle más adelante.Each of the profiles 17 is articulated to the lower frame 2 by means of an elongated pin 23 so that perform an angular path when the frame goes up and down top 4. That is, the direction and relative speed of movement of the cross member 9 at the upper end is equal to that of the upper end of the sliding rod 6, as is will explain in more detail later.

De esta manera, la trayectoria que realiza el bastidor superior 4 cuando se eleva o baja es vertical (indicado por flechas en la figura 1) con respecto a la superficie de apoyo en la cual descansa el bastidor inferior 2.In this way, the trajectory that the upper frame 4 when raised or lowered is vertical (indicated by arrows in figure 1) with respect to the support surface on which the lower frame 2 rests.

En particular, los extremos de cada varilla están guiadas por medio de un elemento de rodadura 10, como por ejemplo una rueda, desplazable a través de una ranura longitudinal 16 o alojamiento, que en el caso del bastidor superior 4 está situada en una porción 20 unida al bastidor superior 4, por ejemplo, por medio de un cordón de soldadura (u otros medios adecuados), tal como se aprecia más claramente en las figuras 4 y 5.In particular, the ends of each rod are guided by a rolling element 10, as by example a wheel, movable through a longitudinal groove 16 or housing, which in the case of the upper frame 4 is located in a portion 20 attached to the upper frame 4, by example, by means of a welding bead (or other means suitable), as seen more clearly in Figures 4 and 5.

Adicionalmente, la parte frontal y posterior de la cama incluyen un tablero de cabecero 11 y un tablero de pies 12 fijados en el bastidor superior 4 a través de elementos de tornillería 19, tal como un sistema de tuerca-tornillo.Additionally, the front and back of the bed includes a headboard 11 and a footboard 12 fixed to the upper frame 4 through elements of screws 19, such as a system of screw nut.

Para aportar una mayor seguridad al paciente alojado en la cama, los dos lados alargados del bastidor superior 4 incluyen una barandilla 13 formada por una pluralidad de barras paralelas provista de un cilindro-pistón 21 para subir y bajar la citada barandilla 13 con el mínimo esfuerzo, habiéndose provisto un pulsador para accionar dicho cilindro-pistón 21. En la figura 6 se ha representado de forma esquematizada la barandilla 13 en una condición bajada y, por lo tanto, de no utilización.To provide greater patient safety housed in the bed, the two elongated sides of the upper frame 4 they include a railing 13 formed by a plurality of bars parallel provided with a piston cylinder 21 for raise and lower the said railing 13 with minimal effort, having provided a button to activate said piston cylinder 21. Figure 6 shows schematically depicted railing 13 in a lowered condition and, therefore, of non-use.

En el bastidor superior 4 se dispone de un somier 18 (véase la figura 6) que presenta diversos tramos a lo largo del mismo articulados entre sí, los cuales permiten adoptar distintas posiciones para el paciente o usuario. Cada tramo incluye unas bielas que se acoplan a la estructura del bastidor superior 4.In the upper frame 4 there is a box spring 18 (see figure 6) that presents various sections at along the same articulated with each other, which allow to adopt different positions for the patient or user. Each section includes connecting rods that fit the structure of the upper frame Four.
