Between the ends (5,6) of the spring component in the longitudinal direction (7) is at least one tension component (4) with adjustable tension and traction. Along the spring component and between the ends on the load side interconnected chain components (1) are so arranged that at least indirectly they support on one another in the longitudinal direction. They are pivotable relatively to one another around pivot axes (8) which run crossways to the longitudinal direction and crossways to the first cross direction.

Description

Elemento en forma de tira.Element in the form of a strip.

El invento hace referencia a un nuevo elemento elástico, que se emplea por ejemplo en los denominados emparrillados de listones y se aplica preferentemente en asientos y divanes. El emparrillado de listones para colchones tiene la mayoría de veces la función de soporte para colchones o tapizados así como la obtención de bases duras para proporcionar confort al dormir o sentarse.The invention refers to a new element elastic, which is used for example in the so-called grilles of slats and is preferably applied in seats and couches. He grid slatting for mattresses has most of the time the support function for mattresses or upholstery as well as obtaining of hard bases to provide comfort when sleeping or sitting.

En algunos emparrillados de listones la dureza puede ajustarse mediante elementos de caucho colocados de manera deslizante entre dos listones elásticos. En otras conocidas construcciones, que se han utilizado para una disposición de base dura de los listones elásticos, la dureza de los listones elásticos se ajusta mediante uno o más elementos elásticos de menor longitud colocados de manera deslizante sobre los listones elásticos.In some grid slats the hardness can be adjusted by rubber elements placed in a manner sliding between two elastic slats. In other known constructions, which have been used for a basic layout hard of the elastic slats, the hardness of the elastic slats is adjusted by one or more elastic elements of shorter length placed slidably on the elastic slats.

Los inconvenientes de estas construcciones son debidos al funcionamiento de los propios listones elásticos. Por motivos estáticos deben estar formados con curvatura convexa en el costado de apoyo, a fin de garantizar una disposición de alturas continuas, así como una correspondiente fuerza de retorno de los listones elásticos. Por necesidades constructivas no puede conseguirse una flexión regular a la presión puntual en cada lugar del listón elástico. Por tanto, con estas conocidas formas de realización no se consigue un ajuste preciso de la dureza básica de los listones elásticos en un emparrillado de cama y en las tres zonas de confort, es decir, las áreas de cabeza, pies y espalda.The disadvantages of these constructions are due to the operation of the elastic slats themselves. By static motifs must be formed with convex curvature in the support side, in order to guarantee a height arrangement continuous, as well as a corresponding return force of the elastic slats. For constructive needs it cannot get a regular flexion at the point pressure in each place of the elastic strip. Therefore, with these known ways of realization is not achieved a precise adjustment of the basic hardness of the elastic slats in a bed grid and in the three comfort zones, that is, the head, foot and back areas.

Debido a estos inconvenientes constructivos de los listones elásticos, un confort para dormir o para estar echado o sentado tan solo puede conseguirse mediante construcciones de colchones y tapizados técnicamente costosos que forzosamente llevan a una elevada altura de constructiva. Por tanto, la ventilación y la eliminación de humedad de los colchones y tapizados se hace más difícil.Due to these constructive inconveniences of the elastic slats, a comfort to sleep or to be thrown or sitting can only be achieved through constructions of technically expensive mattresses and upholsteries that necessarily carry at a high constructive height. Therefore, ventilation and moisture removal of mattresses and upholstery is done more hard.

Este inconveniente de las conocidas construcciones de emparrillados de listones todavía resulta más grave cuando se utilizan en camas de enfermo, en las cuales los pacientes pasan un largo periodo de tiempo. Son utilizadas por distintos pacientes que tienen diferentes pesos, formas corporales individuales y con enfermedades muy distintas, disponiendo normalmente de un emparrillado de listones estandarizado sin ninguna posibilidad de ajuste de la dureza del apoyo. Los simples colchones colocados encima no pueden compensar estos inconvenientes constructivos del emparrillado de listones.This inconvenience of the known slatted grid constructions are still more severe when used in sick beds, in which the Patients spend a long period of time. They are used by different patients who have different weights, body shapes individual and with very different diseases, providing normally of a standardized slat grid without any possibility of adjusting the hardness of the support. The simple mattresses placed above cannot compensate for these inconveniences construction of the slatted grid.

El mismo tipo de problemas se produce en el campo de las sillas para oficina y en los asientos para coche. Tampoco en estos casos se han resuelto de manera óptima las posibilidades individuales de ajuste en lo que respecta la comodidad y el correcto asiento anatómica para los grupos de usuarios.The same type of problems occurs in the field of office chairs and car seats. Neither in these cases have optimally resolved the possibilities individual adjustment in regards to comfort and correct Anatomical seat for user groups.

Para resolver el problema, el invento descrito en la reivindicación 1 y en las reivindicaciones complementarias tiene por objeto crear un elemento elástico cuya dureza pueda ser ajustada simple y exactamente, que debe ser utilizado preferiblemente en emparrillados de listones para camas, sillas de trabajo en oficinas o asientos de coche.To solve the problem, the invention described in claim 1 and in the complementary claims it has to create an elastic element whose hardness can be adjusted simply and exactly, which should preferably be used in slats for bed slats, office work chairs or car seats.

De acuerdo con el invento dicho objeto se consigue por el hecho de que entre los puntos de apoyo en el sentido longitudinal del elemento elástico hay un elemento tensor, que puede inclinarse por lo menos en una primera dirección transversal, y tensarse con tracción previamente ajustada, y de manera que existen elementos de cadena unidos entre sí a lo largo del elemento tensor dispuestos en los costados intermedios de carga de los puntos de apoyo, de tal modo que los elementos de cadena se apoyan uno al otro en el sentido longitudinal y alrededor de los ejes de oscilación, que corren transversales al sentido longitudinal y transversales a la primera dirección transversal, pudiendo bascular unos respecto a otros.According to the invention said object is achieved by the fact that between the points of support in the sense longitudinal of the elastic element there is a tensioning element, which can lean at least in a first transverse direction, and tense with previously adjusted traction, and so that there are chain elements linked together along the tensioning element arranged on the intermediate loading sides of the points of support, so that the chain elements support each other in the longitudinal direction and around the oscillation axes, that run transverse to the longitudinal direction and transverse to the first transverse direction, being able to swing some with respect to others.

Las ventajas conseguidas mediante el invento consisten esencialmente en que el elemento elástico, que puede ajustarse fácil y exactamente en su dureza, resulta especialmente adecuado para camas de enfermo, en casa o en hospitales, clínicas, sanatorios, residencias de ancianos o de asistencia, en que se requieren valores de ajuste especialmente variables respecto a la distribución de presión y profundidades de hundimiento en la zona de apoyo. Además la mayoría de camas de enfermo permiten ajustar la parte de la cabeza y de los pies, y los colchones, que por la necesidad de poder doblarse tiene un menor espesor que un colchón normal para dormir, no pueden ejercer la función de un apoyo anatómico óptimo de la columna vertebral y la parte lumbar. Por tanto tiene especial importancia el emparrillado de listones en lo que respecta a la profundidad de hundimiento y la distribución de la presión.The advantages achieved by the invention essentially consist of the elastic element, which can adjust easily and exactly in its hardness, it is especially suitable for sick beds, at home or in hospitals, clinics, sanatoriums, nursing homes or assistance, where require especially variable adjustment values with respect to the pressure distribution and sinking depths in the area of support for. In addition, most sick beds allow adjusting the part of the head and feet, and the mattresses, which by the The need to bend has a smaller thickness than a mattress normal to sleep, can not exercise the function of a support optimal anatomical spine and lumbar part. By the slat grid is especially important which concerns the depth of sinking and the distribution of the Pressure.

Con el empleo de una cincha superior que puede bascular en sentido transversal, pero que es fija en el sentido longitudinal, se consigue una más amplia profundidad de hundimiento a partir del punto de presión y por tanto una más larga curva de distribución de presión, con un recorrido continuo. Se consigue alcanzar una óptima profundidad de hundimiento en los puntos de apoyo del elemento elástico, por ejemplo utilizando dos emparrillados de listones para una doble cama ancha, con el empleo de dos elementos elásticos combinados entre sí en su sentido de articulación.With the use of a top webbing that can tilting in a transverse direction, but which is fixed in the direction longitudinal, a wider sinking depth is achieved from the pressure point and therefore a longer curve of pressure distribution, with continuous travel. Is achieved reach an optimum depth of sinking at the points of elastic element support, for example using two slats of slats for a double wide bed, with the use of two elastic elements combined with each other in their sense of joint.

En el sector de los asientos, por ejemplo en sillas de trabajo para oficinas, mediante el empleo del elemento elástico en las áreas de asiento y respaldo, se obtiene una silla ampliamente dinámica y capaz de equilibrar las presiones. Gracias al empleo de elementos elásticos con cinchas centrales en el respaldo de asientos para coche puede reducirse la energía que en caso de una colisión trasera causada por otro vehículo recibe el conductor del vehículo que hay delante, el cual es apretado en esta situación contra el respaldo, puesto que el respaldo la amortigua de manera controlada hacia detrás para el conductor.In the seating sector, for example in office work chairs, by using the element elastic in the seat and backrest areas, you get a chair Widely dynamic and able to balance the pressures. Thanks to use of elastic elements with central straps on the backrest of car seats can reduce the energy that in case of a rear-end collision caused by another vehicle receives the driver from vehicle in front, which is tight in this situation against the backrest, since the backrest cushions it so Backward controlled for the driver.

Otra ventajosa forma de realización del invento, además del simple ajuste manual de la dureza del elemento elástico, por ejemplo mediante una llave dinamométrica, puede llevarse a cabo el control programado de la dureza de elementos elásticos individuales mediante software y electromotores de pasos. Esta aplicación resulta especialmente ventajosa en camas de enfermos y de hospitales con un cambio constante de la posición de las camas y diferentes enfermedades de los pacientes. En pacientes de larga permanencia y que necesiten cuidados, desde el punto de vista medico, se puede realizar un control dentro de determinados periodos de la dureza de las diferentes zonas duras o de algunos elementos elásticos a través del control electrónico. A continuación se describirán con más detalle ejemplos de formas de realización del invento haciendo referencia a los dibujos adjuntos.Another advantageous embodiment of the invention, In addition to the simple manual adjustment of the hardness of the elastic element, for example by means of a torque wrench, it can be carried out the programmed control of the hardness of elastic elements individual through software and stepper motors. This application is especially advantageous in sick beds and hospitals with a constant change in the position of the beds and Different diseases of patients. In long patients permanence and need care, from the point of view doctor, a check can be made within certain periods of the hardness of the different hard areas or of some elements Elastic through electronic control. Then you describe in more detail examples of embodiments of the invention referring to the attached drawings.

En la forma de realización de acuerdo con la figura 4, los elementos de cadena 1, en estado sin carga, forman en su conjunto, en sentido transversal con sus dorsos vueltos respecto al elemento tensor 4, un contorno curvado convexo simétrico a espejo. Debido a estas diferentes alturas de los elementos de cadena 1, hasta los extremos 5 y 6, que también forman los puntos de apoyo para el elemento elástico, puede obtenerse una misma profundidad de hundimiento, en cada lugar, entre los extremos 5 y 6.In the embodiment according to the Figure 4, the chain elements 1, in a no-load state, form in as a whole, transversely with its backs turned to the tensioning element 4, a symmetrical convex curved contour to mirror. Due to these different heights of the chain elements 1, to ends 5 and 6, which also form the support points for the elastic element, the same depth of sinking, in each place, between ends 5 and 6.

La figura 5 muestra, con detalle, que los elementos de cadena 1 tan solo están unidos entre sí en la cincha superior 14, y que en los costados frontales 9 únicamente están apretados uno contra el otro, de manera que el inclinarse en un primer sentido transversal dichos costados frontales ruedan uno sobre el otro y el punto de rodadura representa un eje giratorio dispuesto transversalmente.Figure 5 shows, in detail, that chain elements 1 are only attached to each other in the webbing upper 14, and that on the front sides 9 are only pressed against each other, so that leaning on a first transverse direction said front sides roll one on the other and the rolling point represents a rotating shaft arranged transversely.

En la forma de realización de acuerdo con las figuras 6 y 8, los elementos de cadena 1 van fijados a una cincha inferior 15, a fin de conseguir un apoyo central 16 o lateral 17 del elemento elástico, mientras que el elemento tensor 4 pasa sobre el costado superior.In the embodiment according to the Figures 6 and 8, the chain elements 1 are fixed to a webbing lower 15, in order to achieve a central support 16 or lateral 17 of the elastic element, while the tensioning element 4 passes over the upper side.

En la forma de realización de acuerdo con la figura 9, hay un elemento elástico con cincha superior 14 unido con un listón elástico 19 a través de un elemento de enlace 18, a fin de conseguir una profundidad de hundimiento aproximadamente igual de los extremos 5 y 6, como entre los extremos 5 y 6.In the embodiment according to the Figure 9, there is an elastic element with upper strap 14 attached with an elastic strip 19 through a link element 18, in order to achieve a depth of sinking approximately equal to ends 5 and 6, as between ends 5 and 6.

En la forma de realización de acuerdo con la figura 10 hay un corto elemento elástico con cincha inferior 15 y apoyo lateral 17 unido a través de un elemento de enlace 18 con un listón elástico 20 dispuesto sobre el elemento elástico.In the embodiment according to the figure 10 there is a short elastic element with bottom strap 15 and lateral support 17 joined through a link element 18 with a elastic strip 20 arranged on the elastic element.

En la forma de realización según la figura 11 hay dos listones elásticos con diferente inclinación y apoyo unidos entre sí en sentido longitudinal. Esta combinación puede ser ventajosa en la parte del asiento, especialmente aplicada en el campo de sillas.In the embodiment according to figure 11 there are two elastic slats with different inclination and support joined each other longitudinally. This combination can be advantageous in the seat part, especially applied in the field of chairs.

En la forma de realización de acuerdo con la figura 12 hay dispuestos dos elementos elásticos, uno largo con cincha superior 14 y uno corto con cincha inferior 15, a través de un elemento de enlace 18, que corre en el sentido de inclinación 32. Esta combinación de dos elementos elásticos permite una precisa profundidad de hundimiento del elemento de cadena superior en todos los lugares en el sentido longitudinal 7 y es especialmente adecuado para aplicar en camas de enfermo, en conexión con un control electromecánico central, para obtener los diferentes requisitos de dureza, desde el punto de vista médico.In the embodiment according to the Figure 12 there are two elastic elements, one long with upper strap 14 and short one with bottom strap 15, through a link element 18, which runs in the direction of inclination 32. This combination of two elastic elements allows precise sinking depth of the upper chain element in all the places in the longitudinal direction 7 and is especially suitable to apply in sick beds, in connection with a control central electromechanical, to obtain the different requirements of hardness, from a medical point of view.

En la forma de realización de acuerdo con las figuras 13, 14, 15 se muestran ejemplos de realización de un elemento elástico con cincha central 21, que puede aplicarse preferiblemente en el campo de asientos, en especial para respaldos de sillas de oficina o asientos de automóvil, y en que los elementos tensores 4 pasan por ambos costados de dicha cincha central.In the embodiment according to the Figures 13, 14, 15 show examples of embodiment of a elastic element with central strap 21, which can be applied preferably in the field of seats, especially for backrests of office chairs or car seats, and in which elements tensioners 4 pass through both sides of said central web.

En la forma de realización de acuerdo con la figura 19 se ha representado un elemento elástico con cincha superior 14, con elementos de cadena 27 colocados sobre la cincha superior 14 y con elementos de amortiguación y compensación 26 situados entre las superficies frontales 9', que en caso de una carga excesivamente fuerte y distinta de los elementos elásticos, como por ejemplo en bancos para sentarse en el exterior, descarga el elemento tensor 4 o el sistema tensor, respectivamente.In the embodiment according to the Figure 19 an elastic element with strap is shown upper 14, with chain elements 27 placed on the webbing upper 14 and with damping and compensation elements 26 located between the front surfaces 9 ', which in the case of a excessively strong and distinct load of elastic elements, such as on benches to sit outside, download the tensioning element 4 or the tensioning system, respectively.

En la forma de realización de acuerdo con las figuras 25, 26, 27 y 29, se representan las posibilidades de combinación de los elementos elásticos con listones y las combinaciones posibles de los elementos elásticos entre sí. Estos ejemplos de realización muestran ejemplos de aplicación para los sectores de sentarse, descansar y dormir.In the embodiment according to the Figures 25, 26, 27 and 29, the possibilities of combination of elastic elements with slats and possible combinations of elastic elements with each other. These realization examples show application examples for sectors of sitting, resting and sleeping.

Las figuras 29 y 30 muestran una variante en sentido longitudinal y transversal, en que la cincha superior 14 presenta apéndices 14', en especial formados de una pieza, que sobresalen separados contra el elemento tensor 4. Los elementos de cadena 1 van colocados sobre los extremos libres de los apéndices 14' y alojan los miembros en las correspondientes cavidades conformadas, que son algo mayores que los apéndices 14'. La carga sobre la cincha superior, transversal al elemento tensor, deforma dicha cinta superior 14, de manera que bajo determinadas circunstancias tampoco los apéndices 14' siguen exactamente paralelos entre sí, y los elementos de cadena 1 que limitan entre sí ruedan un poco con sus superficies frontales dirigidas una contra la otra 9, con el mismo efecto de una articulación. El elemento tensor 4 puede ser una cincha tensora que está colocada en una ranura inferior del elemento de cadena 1.Figures 29 and 30 show a variant in longitudinal and transverse direction, in which the upper strap 14 it presents appendices 14 ', especially formed of a piece, that protrude apart against the tension element 4. The elements of chain 1 are placed on the free ends of the appendages 14 'and the members lodge in the corresponding cavities shaped, which are somewhat larger than appendices 14 '. Load on the upper strap, transverse to the tensioning element, deforms said upper belt 14, so that under certain circumstances neither the appendices 14 'follow exactly parallel to each other, and the chain elements 1 that limit each other they roll a little with their front surfaces directed one against the another 9, with the same effect of a joint. The tensioning element 4 can be a tension webbing that is placed in a groove bottom of chain element 1.

Por contra, la figura 31 muestra una variante, en que los trozos de tubo de los elementos de cadena 1, que corren en dirección del elemento tensor 4, en este caso consisten en un elemento tensor con sección transversal cilíndrica, como un cable de acero, que se extiende a través del tubo.In contrast, Figure 31 shows a variant, in that the pipe pieces of the chain elements 1, which run in direction of tension element 4, in this case they consist of a tensioning element with cylindrical cross section, such as a cable steel, which extends through the tube.

Dado que los trozos de tubo, que presentan por un costado, y especialmente por ambos extremos, los correspondientes elementos amortiguadores 101, se apoyan con sus superficies frontales 9 en los flancos laterales de apéndices 14' de la cincha superior 14 que corren transversales al sentido de tensión, de modo que también aquí el elemento tensor 4 pasa a través de los trozos de tubo por las correspondientes aberturas de los apéndices 14'.Since the pieces of tube, which present by a side, and especially at both ends, the corresponding damping elements 101, are supported with their surfaces front 9 on the side flanks of appendages 14 'of the webbing upper 14 that run transverse to the sense of tension, so that also here the tensioning element 4 passes through the pieces of tube through the corresponding openings of the appendices 14 '.

Como elemento tensor 1 sirve en primer lugar la parte de la sección transversal de los trozos de tubo situada entre la cincha intermedia superior 14 y el elemento tensor 4, de modo que el punto de articulación del punto de contacto de dichos trozos de tubo se encuentra en los costados frontales 9 contra los apéndices 14'.The tension element 1 serves firstly as part of the cross section of the tube pieces located between the upper intermediate strap 14 and the tensioning element 4, so that the point of articulation of the point of contact of said pieces of tube is located on the front sides 9 against the appendages 14 '.

La figura 33 muestra una variante parecida a la de la figura 29, utilizándose sin embargo como elemento tensor 4 de nuevo un elemento con sección transversal circular, como un cable de acero, cuya principal diferencia reside en la conformación de la cincha superior 14.Figure 33 shows a variant similar to the of figure 29, however, being used as tension element 4 of again an element with circular cross-section, such as a cable steel, whose main difference lies in the conformation of the upper strap 14.

Tal como puede verse en la figura 33, la cincha superior se extiende por ambos costados del apéndice 14' varias veces la anchura del mismo, estando cortado en sentido longitudinal de los costados a intervalos, aproximadamente la profundidad de los apéndices 14' y presentando aberturas de gran superficie en estos sobrantes laterales. Un elemento elástico como este ofrece un apoyo de mayor superficie, sin impedir por completo una ventilación a través de la cincha superior 14 en esta superficie.As can be seen in Figure 33, the webbing upper extends on both sides of appendix 14 'several times the width of it, being cut lengthwise from the sides at intervals, approximately the depth of the appendices 14 'and presenting large surface openings in these leftover side An elastic element like this offers support of greater surface area, without completely preventing ventilation at through the upper strap 14 on this surface.

La figura 35 muestra una forma de realización parecida a la de la figura 25, con la diferencia de que, en el costado del elemento de cadena 1 opuesto respecto al elemento tensor 4 de cada elemento de cadena, va dispuesto un saliente transversal 28 que sobresale lateralmente lejos en sentido transversal del elemento tensor 4, para formar también una ancha superficie de apoyo mediante un único elemento elástico. Los elementos de cadena 1 pueden de este modo unirse entre sí a través de una sola articulación o mediante una cincha superior 14.Figure 35 shows an embodiment similar to that of figure 25, with the difference that, in the side of the opposite chain element 1 with respect to the tension element 4 of each chain element, a transverse projection is arranged 28 protruding laterally far in the transverse direction of the tensioning element 4, to also form a wide support surface by a single elastic element. String elements 1 they can thus join each other through a single articulation or by an upper strap 14.
