Para mayor simplicidad, en lo sucesivo se hará referencia a una única bisagra con la misma orientación de montaje y teniendo en cuenta que para la otra posible bisagra se aplican igualmente las mismas consideraciones constructivas y funcionales.For simplicity, from now on it will be done reference to a single hinge with the same mounting orientation and taking into account that for the other possible hinge they apply equally the same constructive considerations and functional.
En referencia a las figuras 1 y 2, el número 1 indica un medio de conexión sustancialmente plano y bloqueado en un elemento de fijación 10 del lavavajillas, y el número 2 indica un medio de soporte fijado a la puerta que posee el panel opcional. El medio de soporte 2 tiene una forma sustancialmente alargada y se extiende a lo largo de un plano vertical casi paralelo al medio de conexión 1.Referring to figures 1 and 2, the number 1 indicates a substantially flat and locked connection means in a fixing element 10 of the dishwasher, and the number 2 indicates a support means fixed to the door that has the optional panel. He support medium 2 has a substantially elongated shape and is extends along a vertical plane almost parallel to the middle of connection 1.
El medio de soporte 2 está unido al medio de conexión 1 por medio de una manivela 4 y un primer brazo 6.The support means 2 is attached to the means of connection 1 by means of a crank 4 and a first arm 6.
Un extremo de la manivela 4 está abisagrado a través de un primer pivote 5 con el medio de conexión 1 y el otro extremo está conectado, de forma que pueda girar, al medio de soporte 2 por medio de un primer pasador 3.One end of the crank 4 is hinged to through a first pivot 5 with the connection means 1 and the other end is connected, so that it can rotate, to the middle of support 2 by means of a first pin 3.
Un extremo del primer brazo 6 está abisagrado a través de un segundo pivote 9 con el medio de conexión 1 y el otro extremo está conectado, de forma que pueda girar, al medio de soporte 2 por medio de un segundo pasador 7.One end of the first arm 6 is hinged to through a second pivot 9 with the connection means 1 and the other end is connected, so that it can rotate, to the middle of support 2 by means of a second pin 7.
Los pivotes primero 5 y segundo 9, y los pasadores primero 3 y segundo 7, poseen puntos de apoyo y ejes respectivamente ortogonales al plano del medio de conexión 1. El primer pivote 5 está fijado a la puerta más cerca que el segundo pivote 9, y está fijado bajo éste. El primer pasador 3 está situado cerca de una parte periférica inferior del medio de soporte 2 y el segundo pasador 7 tiene una posición más central que el desarrollo longitudinal del medio de soporte 2.The first 5 and second 9 pivots, and the first 3 and second 7 pins, have support points and shafts respectively orthogonal to the plane of the connection means 1. The first pivot 5 is fixed to the door closer than the second pivot 9, and is fixed under it. The first pin 3 is located near a lower peripheral part of the support means 2 and the second pin 7 has a more central position than the development longitudinal of the support means 2.
La distancia entre los pivotes primero 5 y segundo 9 es mayor que la distancia entre los pasadores primero 3 y segundo 7, a fin de provocar, cambiando de un estado de cierre C de la puerta a un estado de apertura A de la misma puerta, su elevación y alejamiento de la abertura relacionada del lavavajillas o aparato.The distance between the pivots first 5 and second 9 is greater than the distance between the first 3 pins and second 7, in order to cause, changing from a closed state C of the door to an opening state A of the same door, its lifting and moving away from the related opening of the dishwasher or device
La bisagra incluye unos medios de equilibrio 11, consistentes por ejemplo en un muelle 13 tensado y que reacciona en extensión o compresión, y unos medios de leva 15 constituidos por una placa que posee, aproximadamente, forma cuadrangular.The hinge includes balancing means 11, consisting, for example, of a spring 13 tensioned and reacting in extension or compression, and cam means 15 constituted by a plate that has approximately quadrangular shape.
Un extremo de los medios de equilibrio 11 está fijado a los medios de fijación 10, y el otro extremo está fijado a un vértice de la placa 15 de forma que pueda girar, mientras que el vértice opuesto está conectado en cascada, de forma que pueda girar, a unos elementos articulados 8 y al medio de soporte 2. Por consiguiente, un movimiento relacionado de los medios de leva 15, contrarrestado por los medios de equilibrio 11, corresponde a cada movimiento de la puerta desde el estado de cierre C al estado de apertura A y viceversa. Después, los medios de equilibrio 11, por medio de los elementos articulados 8 y el medio de soporte 2, ejercen una fuerza elástica de cierre sobre el par de fuerzas de apertura generado por el peso de la puerta y transmitidos por ésta al medio de soporte 2.One end of the balancing means 11 is fixed to the fixing means 10, and the other end is fixed to a vertex of the plate 15 so that it can rotate, while the opposite vertex is cascaded, so that you can turn, to articulated elements 8 and to the support means 2. By consequently, a related movement of cam means 15, offset by balancing means 11, corresponds to each door movement from the closing state C to the state of A opening and vice versa. Then, the balancing means 11, by means of the articulated elements 8 and the support means 2, exert an elastic closing force on the torque force of opening generated by the weight of the door and transmitted by it to the support medium 2.
Unos medios de fricción 14 están conectados, de forma que puedan girar, a los dos vértices restantes de la placa 15, por medio de pernos 17. Los medios de fricción 14 se deslizan sobre los medios de leva 15 entre dos paredes 12 del medio de conexión 1. Las paredes 12 son casi paralelas y perpendiculares al plano definido por el medio de conexión 1.Friction means 14 are connected, of so that they can rotate, to the two remaining vertices of the plate 15, by means of bolts 17. The friction means 14 slide on cam means 15 between two walls 12 of the means of connection 1. The walls 12 are almost parallel and perpendicular to the plane defined by the connection means 1.
Los medios de equilibrio 11 y los elementos articulados 8 transmiten a los medios de leva 15 respectivamente una fuerza elástica de cierre y una fuerza de reacción. Estas fuerzas opuestas están desalineadas y, por lo tanto, ejercen un par de rotación en los medios de leva 15, que hace que éstos giren. El par de fuerzas de rotación se transmite mediante los medios de leva 15 a los medios de fricción 14, que, por consiguiente, transmiten un par de reacción a las paredes 12. Después, cada medio de fricción 14 ejerce una presión contra la respectiva pared 12, que produce fricciones mutuas, particularmente fricción estática y un contrapesado de la puerta.The means of balance 11 and the elements articulated 8 transmitted to cam means 15 respectively an elastic closing force and a reaction force. These opposing forces are misaligned and therefore exert a pair of rotation in the cam means 15, which causes them to rotate. He torque of rotation forces is transmitted by means of cam 15 to the friction means 14, which, therefore, transmit a pair of reaction to the walls 12. Next, each friction means 14 exerts a pressure against the respective wall 12, which produces mutual friction, particularly static friction and a Weighted door.
Los bordes longitudinales libres de las paredes 12 están doblados hacia el interior del medio de conexión 1, uno hacia el otro, de tal forma que se impide que los medios de fricción 14 se desacoplen de dicho medio de conexión.Free longitudinal edges of the walls 12 are bent into the connection means 1, one towards the other, so that friction means is prevented 14 are decoupled from said connection means.
Por ejemplo, los medios de fricción 14 consisten en bloques deslizantes o rodillos guía 16 aptos para deslizarse con fricción sobre las paredes 12. El bloque deslizante o los rodillos guía 16 están hechos de un material plástico caracterizado por un coeficiente de fricción predeterminado para crear tales fuerzas de fricción para contrapesar un peso total de la puerta y/o panel, que oscila entre 6 y 14 kilogramos.For example, friction means 14 consist in sliding blocks or guide rollers 16 suitable for sliding with friction on the walls 12. The sliding block or rollers guide 16 are made of a plastic material characterized by a predetermined coefficient of friction to create such forces of friction to weigh a total weight of the door and / or panel, which It ranges between 6 and 14 kilograms.
Los elementos articulados 8 incluyen una biela 20 cuyo extremo está conectado respectivamente, de forma que pueda girar, al primer pasador 3 y a un primer extremo del balancín 21 que pivota centralmente sobre el medio de conexión 1 por medio de un tercer pivote 23. Los elementos articulados 8 incluyen además un segundo brazo 22 cuyos extremos están conectados respectivamente, de forma que puedan girar, al segundo extremo del balancín 21 y a los medios de equilibrio 11 para convertir el movimiento del medio de soporte 2 en un movimiento lineal de los medios de leva 15.The articulated elements 8 include a connecting rod 20 whose end is connected respectively, so that it can turn, to the first pin 3 and to a first end of the rocker 21 which pivots centrally on the connection means 1 by means of a third pivot 23. The articulated elements 8 further include a second arm 22 whose ends are connected respectively, so that they can turn, to the second end of rocker 21 and to balancing means 11 to convert the movement of the medium of support 2 in a linear movement of the cam means 15.
El dispositivo de bisagra incluye además unos medios deslizantes 24 fijados al medio de conexión 1 e interpuestos entre éste y el medio de soporte 2 con el fin de impedir el huelgo transversal de la puerta, encajando de forma deslizante con el medio de soporte 2.The hinge device also includes some sliding means 24 fixed to the connection means 1 and interposed between it and the support means 2 in order to prevent the strike transverse of the door, sliding fit with the support medium 2.
La bisagra también incluye un medio de bloqueo 25 y un medio de parada 26 realizados respectivamente en el medio de conexión 1 y en el medio de soporte 2. Los medios de parada 26 encajan con el medio de bloqueo 25, correspondiendo al estado de apertura A.The hinge also includes a locking means 25 and a stop means 26 performed respectively in the middle of connection 1 and in the support means 2. The stop means 26 they fit with the locking means 25, corresponding to the state of opening A.
Durante el funcionamiento de la bisagra, al cambiar del estado de cierre C al estado de apertura A, la puerta tensa la bisagra con un par de apertura que aumenta progresivamente, ya que el peso de la puerta funciona con un brazo que aumenta progresivamente. Se producen simultáneamente la extensión de los medios de equilibrio 11 y el aumento de la fuerza elástica transmitida a los medios de leva 15 y al medio de soporte 2. Por consiguiente, hay un aumento en la presión ejercida por los medios de fricción 14 contra las paredes respectivas 12 y un aumento de la fuerza de cierre ejercida por los medios de equilibrio 11. La elevación progresiva de la presión aumenta el par de apertura, permitiendo que la puerta también se detenga en estados próximos al estado de apertura A. El aumento de la fuerza de cierre contribuye al equilibrio del par de apertura.During hinge operation, when change from the closing state C to the opening state A, the door tighten the hinge with an opening pair that increases progressively, since the weight of the door works with an arm that increases progressively Simultaneously the extension of the balancing means 11 and increasing elastic force transmitted to cam means 15 and support medium 2. By consequently, there is an increase in the pressure exerted by the media of friction 14 against the respective walls 12 and an increase in the closing force exerted by the balancing means 11. The progressive rise in pressure increases the opening torque, allowing the door to also stop in states near the opening state A. Increasing the closing force contributes to the balance of the opening torque.
Una variante de la bisagra prevé que las paredes 12, en lugar de ser paralelas, puedan ser convergentes. La convergencia aproximadamente en dirección al primer pivote 5 aumenta progresivamente la presión ejercida por los medios de fricción 14 contra las paredes 12, y, por tanto, las fricciones que cambian del estado de cierre C al estado de apertura A.A variant of the hinge provides that the walls 12, instead of being parallel, they can be convergent. The convergence approximately towards the first pivot 5 increases progressively the pressure exerted by the friction means 14 against walls 12, and therefore the frictions that change from closing state C to opening state A.
También resulta útil destacar que la convergencia en la dirección opuesta provoca los efectos opuestos.It is also useful to note that the convergence in the opposite direction causes the effects opposites
Particularmente, la variante que se muestra en las figuras 3 y 4 pone de relieve que la pared más alejada 12 del medio de soporte 2 está inclinada hacia el pivote 5 mientras que la pared más próxima 12 al soporte 2 es casi paralela al mismo, correspondiendo al estado de cierre C.Particularly, the variant shown in Figures 3 and 4 show that the farthest wall 12 of the support means 2 is inclined towards pivot 5 while the nearest wall 12 to support 2 is almost parallel to it, corresponding to the closing state C.
Esta variante también prevé que la fuerza elástica de cierre de los medios de equilibrio 11 y la fuerza de reacción de los elementos articulados 8 estén ligeramente desalineadas, por ejemplo de 1 a 5 milímetros y preferentemente 2,5 milímetros, correspondiendo al estado de cierre C, de forma que al cambiar de este estado al estado de apertura A, el bloque deslizante 16, o el rodillo guía, que se desliza sobre la pared inclinada 12 provocan la rotación de la placa 15 y la desalineación progresiva de la fuerza elástica de cierre con respecto a la fuerza de reacción y el aumento progresivo del brazo de dicho par y la intensidad de dicho par a fin de transmitir un par de fuerzas de rotación progresivamente más alto, que se transmite a los medios de fricción 14 mediante los medios de leva 15. Por tanto, estos medios de fricción 14 trasmiten a las paredes 12 un par de reacción progresivamente mayor y de tal forma que contrapese de forma continua el aumento de la fuerza del peso de la puerta y el panel opcional durante la apertura.This variant also provides that the force elastic closing of the balancing means 11 and the force of reaction of articulated elements 8 are slightly misaligned, for example 1 to 5 millimeters and preferably 2.5 millimeters, corresponding to the closing state C, so that at change from this state to the opening state A, the block slide 16, or the guide roller, which slides over the wall inclined 12 cause plate rotation 15 and misalignment progressive closing force with respect to the force of reaction and the progressive increase of the arm of said pair and the intensity of said pair in order to transmit a pair of forces of progressively higher rotation, which is transmitted to the means of friction 14 via cam means 15. Therefore, these means of friction 14 transmit a reaction torque to the walls 12 progressively greater and in such a way that it weights in a way the increase in the force of the door and panel weight continues optional during opening.
Y a la inversa, al mover la puerta entre el estado de apertura A y el estado de cierre C, el juego de fuerzas es el opuesto y, por tanto, se garantiza el contrapesado continuo de la puerta que permanece equilibrada en cualquier posición entre los dos estados, apertura A y cierre C.And conversely, by moving the door between the opening state A and closing state C, the set of forces it is the opposite and, therefore, the continuous counterbalance of the door that remains balanced in any position between the two states, opening A and closing C.
La principal ventaja de la presente invención consiste en proporcionar un dispositivo de bisagra para abrir y cerrar una puerta, también con un panel, sin interferencias con rodapiés u otros elementos cercanos o situados bajo la puerta, y apto para contrapesar la puerta contrarrestando el peso de la misma y permitiendo su parada en cualquier posición final o intermedia.The main advantage of the present invention is to provide a hinge device to open and close a door, also with a panel, without interference with skirting boards or other elements near or located under the door, and suitable to counterbalance the door by counteracting the weight of the door and allowing your stop at any final position or intermediate.
Otra ventaja es la de proporcionar una bisagra para contrapesar puertas que posean un peso que varía en un amplio intervalo, sin necesidad de correcciones o ajustes.Another advantage is to provide a hinge to counterbalance doors that have a weight that varies widely interval, without the need for corrections or adjustments.
Otra ventaja de la presente invención es la de proporcionar un dispositivo de bisagra muy fácil de fabricar y usar y muy económico.Another advantage of the present invention is that of provide a hinge device very easy to manufacture and use And very economical.
