Description
Bisagra de puerta.Door hinge.
La presente invención se refiere a una bisagra para una puerta y en particular a una bisagra que se puede usar para vincular una puerta de electrodomésticos, tales como hornos, a las respectivas estructuras de soporte.The present invention relates to a hinge for a door and in particular to a hinge that can be used to link a door of appliances, such as ovens, to the respective support structures.
Las bisagras de este tipo se componen de dos partes separadas, ambas con una estructura con forma de caja y relacionadas entre sí cinemáticamente.Hinges of this type are made up of two separate parts, both with a box-shaped structure and kinematically related to each other.
Más exactamente, la primera de esas partes se fija a la estructura del horno de un lado de su abertura rectangular, mientras que la segunda parte se fija a un borde de la puerta, que de esta manera se puede mover, girando con respecto a la abertura.More exactly, the first of those parts is fixed to the oven structure on one side of its opening rectangular, while the second part is fixed to an edge of the door, which in this way can be moved, turning with respect to The opening.
Dichas primera y segunda estructura con forma de caja están conectadas entre sí por medio de una palanca, el extremo de un primer brazo de la palanca estando conectado rígidamente a la primera estructura con forma de caja, mientras que el extremo de un segundo brazo de la palanca estando abisagrado a la segunda estructura con forma de caja a través de un perno.Said first and second structure shaped box are connected to each other by means of a lever, the end of a first lever arm being rigidly connected to the first box-shaped structure, while the end of a second lever arm being hinged to the second box-shaped structure through a bolt.
Como consecuencia de lo anterior, durante la rotación de la puerta, en su dirección de apertura o en la dirección opuesta, es decir en la dirección de cierre, la segunda estructura con forma de caja gira alrededor del perno.As a consequence of the above, during the door rotation, in its opening direction or in the direction opposite, that is, in the closing direction, the second structure Box-shaped revolves around the bolt.
La segunda estructura con forma de caja también incluye parte de los medios internos para ajustar la apertura de la puerta y, más en particular, medios que, durante la apertura de la puerta, primero producen que la misma gire rápidamente de un ángulo de una determinada amplitud y luego que se abra gradualmente a baja velocidad, oponiéndose al peso de la misma puerta, hasta que quede totalmente abierta.The second box-shaped structure also includes part of the internal means to adjust the opening of the door and, more particularly, means that, during the opening of the door, first produce that it rotates quickly from an angle of a certain amplitude and then gradually open at low speed, opposing the weight of the same door, until it remains fully open
Esos medios internos de ajuste, del tipo conocido, comprenden una varilla colocada dentro de la segunda estructura con forma de caja. La parte inferior de la varilla está conectada, mediante un segundo perno, paralelo con el perno para la rotación de la segunda estructura con forma de caja, al segundo brazo de la palanca.Those internal means of adjustment, of the type known, comprise a rod placed inside the second box-shaped structure. The bottom of the rod is connected, by a second bolt, parallel with the bolt for the rotation of the second box-shaped structure, to the second lever arm.
Los medios internos de ajuste también comprenden primeros medios elásticos que presionan la varilla sobre el segundo perno, generando un momento de fuerza con respecto al primer perno que se transmite a través de la varilla y la segunda estructura con forma de caja a la puerta en una dirección que se opone a la apertura de la puerta, lo que equivale a decir, tendiendo a que gire alrededor del primer perno en la dirección opuesta a la de apertura de la puerta.The internal adjustment means also comprise first elastic means that press the rod on the second bolt, generating a moment of force with respect to the first bolt which is transmitted through the rod and the second structure with box shape to the door in a direction that opposes the door opening, which is equivalent to saying, tending to turn around the first bolt in the opposite direction to that of door opening.
Los medios internos también comprenden segundos medios elásticos adecuados para generar un segundo momento de fuerza que, durante las etapas iniciales de apertura de la puerta, se oponen al primer momento de fuerza y lo superan de manera que la puerta realice un rápido movimiento de apertura del ya mencionado ángulo de una determinada amplitud.The internal media also comprise seconds suitable elastic means to generate a second moment of force that, during the initial stages of opening the door, oppose the first moment of strength and overcome it so that the door perform a rapid opening movement of the aforementioned angle of a certain amplitude.
Más exactamente, los segundos medios elásticos se componen de un resorte espiralado envuelto de manera deslizante alrededor de un árbol y situado entre una aleta de tope solidaria con la segunda estructura configurada con forma de caja y un saliente del árbol.More precisely, the second elastic means they consist of a spiral spring wrapped in a sliding way around a tree and located between a solidary butt fin with the second box-shaped structure configured and a outgoing from the tree.
Un extremo del árbol soporta un tercer perno con un eje paralelo a los ejes de dichos primer y segundo perno y cuyos extremos opuestos se deslizan dentro de una ranura con una dada longitud hecha en la segunda estructura con forma de caja, la cual tiene el cometido de guiar y limitar la carrera del perno. En el tercer perno hay un rodillo loco. Cuando la puerta está cerrada y durante las fases iniciales de apertura de la puerta, el rodillo loco se apoya sobre un perfil de leva hecho sobre el borde superior de la palanca y se separa del borde cuando la puerta ha superado el antes mencionado ángulo de amplitud determinada.One end of the shaft supports a third bolt with an axis parallel to the axes of said first and second bolts and whose opposite ends slide into a slot with a given length made in the second box-shaped structure, which It has the task of guiding and limiting the bolt stroke. At Third bolt there is a crazy roller. When the door is closed and during the initial phases of opening the door, the roller crazy lean on a cam profile made over the top edge of the lever and separates from the edge when the door has exceeded the aforementioned angle of amplitude determined.
Durante la etapa de contacto del rodillo y la leva, el resorte espiralado se comprime entre la aleta y el saliente del árbol.During the contact stage of the roller and the cam, the spiral spring is compressed between the fin and the outgoing from the tree.
Como consecuencia de lo anterior, la leva transmite, a través del rodillo, el árbol, el resorte espiralado y la aleta de tope, el segundo momento de fuerza a la segunda estructura con forma de caja y, por ende, a la puerta, que tiende a hacer girar la puerta en su dirección de apertura.As a consequence of the above, the cam transmits, through the roller, the tree, the spiral spring and the butt fin, the second moment of force to the second box-shaped structure and, therefore, at the door, which tends to Turn the door in its opening direction.
Sin embargo, en la práctica los medios de conexión para la transmisión del segundo momento de fuerza son relativamente complejos, así como también caros con respecto a sus prestaciones.However, in practice the means of connection for the transmission of the second moment of force are relatively complex, as well as expensive with respect to their benefits.

Con referencia a las figuras 1, 2 y 3, el número 1 indica un horno, en su totalidad, que comprende un bastidor (2) en cuyo fondo está vinculada una puerta (3) mediante dos bisagras (4), las cuales permiten que la puerta gire alrededor de un eje horizontal (5).With reference to figures 1, 2 and 3, the number 1 indicates an oven, in its entirety, comprising a frame (2) at the bottom of which a door (3) is linked by two hinges (4), which allow the door to rotate around an axis horizontal (5).
Tal como se exhibe en particular en las figuras 2 y 3, cada una de las dos bisagras (4) es una bisagra hecha de una primera estructura con forma de caja (6) fijada al bastidor (2) del horno (1), y una segunda estructura con forma de caja (7) fijada a la puerta (3). Las dos estructuras con forma de caja (6 y 7) están conectadas cinemáticamente mediante una palanca (8), cuyo primer brazo (8') está fijado rígidamente a la primera estructura con forma de caja (6) y cuyo segundo brazo (8'') está fijado, mediante un perno (9) que pasa a través de un orificio (9') en correspondencia del extremo del segundo brazo (8'') y coaxial con el eje (5), a la segunda estructura (7). La segunda estructura comprende una varilla (10) situada longitudinalmente dentro de la misma segunda estructura (7) y conectada en correspondencia de su extremo inferior, mediante un perno (11) paralelo con el perno (9) y que pasa a través de un orificio (11') en una sección intermedia del segundo brazo (8'') de la palanca (8), a esta última, de manera que la varilla (10) pivote alrededor de un eje (12) del perno (11) que pasa a través del orificio (11') de la palanca (8).As shown in particular in the figures 2 and 3, each of the two hinges (4) is a hinge made of one first box-shaped structure (6) fixed to the frame (2) of the oven (1), and a second box-shaped structure (7) fixed to the door (3). The two box-shaped structures (6 and 7) are kinematically connected by a lever (8), whose first arm (8 ') is rigidly fixed to the first structure with box shape (6) and whose second arm (8``) is fixed, by a bolt (9) passing through a hole (9 ') in correspondence of the end of the second arm (8``) and coaxial with the axis (5), to the second structure (7). The second structure it comprises a rod (10) located longitudinally within the same second structure (7) and connected in correspondence of its lower end, by means of a bolt (11) parallel with the bolt (9) and passing through a hole (11 ') in an intermediate section from the second arm (8``) of the lever (8), to the latter, so that the rod (10) pivots around an axis (12) of the bolt (11) passing through the hole (11 ') of the lever (8).
La segunda estructura con forma de caja (7) comprende primeros medios (13) para ajustar la apertura de la puerta (3) que se componen de medios elásticos (14), en particular se componen de un resorte espiralado (15) substancialmente coaxial con la varilla (10) y que operan por tracción, como se describirá con mayores detalles abajo, un extremo del cual está conectado al extremo superior de la estructura (7) mediante una traviesa (16) mientras que el otro extremo está conectado a un orificio (17) de una pared lateral de la varilla (10).The second box-shaped structure (7) comprises first means (13) to adjust the opening of the door (3) which are composed of elastic means (14), in particular they consist of a spirally coiled spring (15) substantially with the rod (10) and operating by traction, as will be described in more detail below, one end of which is connected to the upper end of the structure (7) by a crossbar (16) while the other end is connected to a hole (17) of a side wall of the rod (10).
Cabe hacer notar que los pernos (9 y 11) no se mueven durante la rotación de la puerta (3) y, por ende, la rotación de la segunda estructura con forma de caja (7) y durante la rotación en ambas direcciones, entre una posición límite cerrada y una posición límite totalmente abierta, la segunda estructura con forma de caja (7) gira alrededor del eje (5) del perno (9) y la varilla (10) gira alrededor del eje (12) del perno (11). Tal como se exhibe en las figuras 2 y 3, el emplazamiento recíproco de los dos pernos (9 y 11) es tal que durante la apertura de la puerta (3) el resorte espiralado (15) es sometido a tracción por la varilla interna (10), generando un momento de fuerza (M1), antihorario en las figuras 2 y 3, con respecto al eje (5), que se opone a la apertura de la puerta (3) para regular la velocidad de bajada de la puerta mientras se abre.It should be noted that the bolts (9 and 11) are not move during the rotation of the door (3) and, therefore, the rotation of the second box-shaped structure (7) and during rotation in both directions, between a closed limit position and a fully open limit position, the second structure with box shape (7) rotates around the shaft (5) of the bolt (9) and the rod (10) rotates around the shaft (12) of the bolt (11). Such as the reciprocal location of the two bolts (9 and 11) is such that during the opening of the door (3) the spiral spring (15) is tensioned by the rod internal (10), generating a moment of force (M1), counterclockwise in Figures 2 and 3, with respect to the axis (5), which opposes the door opening (3) to regulate the lowering speed of the door while it opens.
Tal como se muestra en las figuras 2, 3 y 4, la segunda estructura con forma de caja (7) además comprende segundos medios (18) para ajustar la apertura de la puerta (3), que se componen de un elemento elástico (19), en particular configurado en U y realizado de alambre metálico. El elemento comprende dos brazos (20) y una porción intermedia (21). Cada uno de los dos brazos (20) forma un resorte flector (22) que en particular se compone de un arrollamiento con un eje (24) substancialmente paralelo con la porción intermedia (21) y con el eje (5) de rotación de la bisagra (4).As shown in Figures 2, 3 and 4, the second box-shaped structure (7) also comprises seconds means (18) for adjusting the door opening (3), which is they consist of an elastic element (19), in particular configured in U and made of metallic wire. The element comprises two arms (20) and an intermediate portion (21). Each of the two arms (20) it forms a bending spring (22) which in particular consists of a winding with an axis (24) substantially parallel with the intermediate portion (21) and with the axis (5) of rotation of the hinge (4).
La porción intermedia (20) del elemento elástico (19) está conectada a la pared de fondo (25) de la segunda estructura con forma de caja (7) a través de medios de vinculación (26) que se componen de medios de acoplamiento de rápida liberación (27). En particular, los medios (27) comprenden una aleta (28) sobre la pared (25) y que se extiende hacia el resorte (15) para crear un asiento (29) para la porción intermedia (21) del elemento elástico (19).The intermediate portion (20) of the elastic element (19) is connected to the back wall (25) of the second box-shaped structure (7) through linking means (26) which consist of quick release coupling means (27). In particular, the means (27) comprise a fin (28) on the wall (25) and extending towards the spring (15) to create a seat (29) for the intermediate portion (21) of the elastic element (19).
Los extremos de los dos brazos (20) del elemento elástico (19) están envueltos en anillo y soportan los extremos de un perno (30) cuyo eje (31) es paralelo al eje (24) y sobre el cual está colocado de manera giratoria un rodillo (32).The ends of the two arms (20) of the element elastic (19) are wrapped in a ring and support the ends of a bolt (30) whose axis (31) is parallel to the axis (24) and on which a roller (32) is rotatably placed.
En las paredes laterales opuestas (33), substancialmente normales a la pared de fondo (25) de la segunda estructura con forma de caja (7) hay dos ranuras (34) que se extienden a lo largo de una sección de una longitud determinada en una dirección substancialmente paralela al eje del resorte espiralado (15). La ranuras son adecuadas para recibir los extremos opuestos del perno (30) el cual soporta el rodillo (32) adecuado para vincularse de manera deslizante con una porción (35) dada del borde superior de la palanca (8) que forma un perfil de leva cuya función está descrita más adelante.On opposite side walls (33), substantially normal to the bottom wall (25) of the second box-shaped structure (7) there are two slots (34) that are extend along a section of a certain length in a direction substantially parallel to the spring axis spiral (15). The slots are suitable to receive the ends opposite the bolt (30) which supports the appropriate roller (32) to slide in a sliding manner with a given portion (35) of the upper edge of the lever (8) forming a cam profile whose function is described later.
En condiciones en las cuales hay contacto entre el rodillo (32) y la porción (35) del borde superior de la palanca (8), los enrollamientos (23) de los dos resortes de flexión (22) del elemento elástico (19) son sometidos a una flexión substancialmente alrededor del eje (24), generando un momento de fuerza (M2) opuesto al momento (M1) (horario en las figuras 2 y 3), con respecto al eje (5) de la segunda estructura con forma de caja (7) y, por ende, con respecto a la puerta (3), haciendo que esta última gire en su dirección de apertura.In conditions in which there is contact between the roller (32) and the portion (35) of the upper edge of the lever (8), the curls (23) of the two bending springs (22) of the elastic element (19) are substantially flexed around the axis (24), generating a moment of force (M2) opposite at the moment (M1) (schedule in figures 2 and 3), with respect to the axis (5) of the second box-shaped structure (7) and, therefore, with with respect to the door (3), making the latter turn in its opening address
El número 36 designa un dispositivo de rápido bloqueo/liberación de la puerta (3). El dispositivo (36), de tipo conocido, trabaja entre la puerta (3) y el bastidor (2) y, después de cada operación manual de cierre de la puerta (3), puede mantener la puerta cerrada hasta que el dispositivo (36) se active manualmente, usando un pulsador de control (37), eliminando todo impedimento para abrir la puerta (3).The number 36 designates a fast device door lock / release (3). The device (36), of type known, works between the door (3) and the frame (2) and then For each manual door closing operation (3), you can keep the door closed until the device (36) is activated manually, using a control button (37), removing all impediment to open the door (3).
En la práctica, con referencia a la patente de invención europea EP 0.632.180, y comenzando con la puerta (3) en su condición de cerrada exhibida en la figura 2, en la cual el rodillo (32) está en contacto con la sección inicial de la porción (35) del borde superior de la palanca (8), después de la activación del pulsador de control (37) las bisagras (4) primero provocan una rotación de apertura relativamente rápida de la puerta (3) que cubre un dado espacio angular, luego un movimiento de apertura frenado gradualmente, hasta que la puerta (3) quede totalmente abierta.In practice, with reference to the patent of European invention EP 0.632.180, and starting with the door (3) in its closed condition shown in figure 2, in which the roller (32) is in contact with the initial section of the portion (35) of the upper edge of the lever (8), after activation of the control button (37) the hinges (4) first cause a relatively fast opening rotation of the door (3) that covers a given angular space, then an opening movement braking gradually, until the door (3) is fully open
Más exactamente, la etapa inicial de apertura rápida se produce gracias a la supremacía del momento de fuerza M2 generado por el elemento elástico (19) sobre el momento de fuerza M1 generado por el resorte espiralado (15). Esta etapa termina cuando el rodillo (32) se separa de la porción (35) del borde superior de la palanca (8), lo que equivale a decir, cuando la segunda estructura con forma de caja (7) alcanza la posición denotada con 38. En esta posición los extremos del perno (30) que soporta el rodillo (32) alcanzan la posición de final de carrera a lo largo de las respectivas ranuras (34) y el rodillo (32) deja de estar en contacto con la porción (35) del borde superior de la palanca (8).More exactly, the initial opening stage rapid is produced thanks to the supremacy of the moment of force M2 generated by the elastic element (19) on the moment of force M1 generated by the spiral spring (15). This stage ends when the roller (32) is separated from the portion (35) of the upper edge of the lever (8), which is equivalent to saying, when the second box-shaped structure (7) reaches the position denoted with 38. In this position the ends of the bolt (30) that supports the roller (32) reach the limit switch position along the respective grooves (34) and the roller (32) are no longer in contact with the portion (35) of the upper edge of the lever (8).
Después de lo anterior la puerta (3), bajo la acción combinada de su peso que facilita su rotación de bajada y la acción de frenado provocada por el momento de fuerza (M1) a través del resorte espiralado (15) completa su etapa de apertura girando gradualmente hasta la posición denotada con 39 en la figura 2.After the above the door (3), under the combined action of its weight that facilitates its downward rotation and braking action caused by force moment (M1) through of the spiral spring (15) completes its opening stage by turning gradually to the position denoted with 39 in figure 2.
Como se muestra en la figura 5, para regular la intensidad del momento M1 y, por consiguiente, su acción de frenado sobre la puerta (3), hay medios (40) para ajustar la tensión del resorte de tracción (15). Esos medios (40) comprende medios de ajuste de rosca (41) para el punto de vinculación de uno de los dos extremos del resorte (15). La rosca (42) de los medios (41) se puede fijar en un extremo de una placa (43) que tiene una pluralidad de orificios (44) para la vinculación del extremo del resorte (15). Como se muestra en la figura 2, para ajustar la tensión del resorte (15) el extremo inferior del resorte (15) se puede vincular a uno de los orificios (17) de la varilla (10).As shown in Figure 5, to regulate the intensity of the moment M1 and, consequently, its braking action on the door (3), there are means (40) to adjust the tension of the tension spring (15). Those means (40) comprise means of thread adjustment (41) for the point of attachment of one of the two spring ends (15). The thread (42) of the means (41) is can be fixed at one end of a plate (43) that has a plurality of holes (44) for linking the end of the spring (15). As shown in Figure 2, to adjust the spring tension (15) the lower end of the spring (15) is You can link to one of the holes (17) of the rod (10).
Cabe hacer notar que, para facilitar y acelerar las operaciones de ensamblado de la bisagra (4) a la puerta (3), la segunda estructura con forma de caja (7) tiene medios de acoplamiento rápido (45) adecuados para operar conjuntamente con medios de alojamiento en un asiento (46) de la puerta (3) en el cual está encastrada la segunda estructura (7).It should be noted that, to facilitate and accelerate the assembly operations of the hinge (4) to the door (3), the second box-shaped structure (7) has means of quick coupling (45) suitable to operate together with accommodation means in a seat (46) of the door (3) in which the second structure (7) is embedded.
En particular, los medios de acoplamiento rápido (45) se componen de una aleta (47) sobresaliente de la parte externa de la segunda estructura con forma de caja (7).In particular, quick coupling means (45) are composed of a fin (47) protruding from the part external of the second box-shaped structure (7).
