• un marco horizontal que rodea una abertura, estando dicho marco dotado de una porcion de bisagra de marco hueca;• a horizontal frame surrounding an opening, said frame being provided with a hollow frame hinge portion;
• una tapa prevista para un cierre ajustado de dicha abertura, estando la tapa dotada de unas caras anterior y posterior, y de una porcion de bisagra de tapa complementaria y acoplable a la porcion de bisagra de marco hueca, permitiendo la rotacion de la tapa alrededor de un eje de articulacion;• a cover provided for a tight closing of said opening, the cover being provided with front and rear faces, and a complementary hinge portion complementary to the hollow frame hinge portion, allowing the lid to rotate around of an axis of articulation;
• un extremo retenedor de la porcion de bisagra de tapa en forma de resalte dispuesto en su extremo mas alejado respecto a la tapa;• a retaining end of the hinge portion of the lid-shaped projection disposed at its furthest end from the lid;
• un apendice de la porcion de bisagra de marco configurado para entrar en interferencia geometrica con un extremo retenedor de la porcion de bisagra de tapa, estando la tapa en posicion de cierre, impidiendo el desplazamiento ascendente de la tapa;• an appendix of the frame hinge portion configured to enter geometric interference with a retaining end of the lid hinge portion, the lid being in the closed position, preventing upward displacement of the lid;
proporcionando, la interaction de las porciones de bisagra de tapa y de marco, tres posiciones de bloqueo de la tapa respecto al marco, una posicion cerrada, una posicion de apertura intermedia, y una posicion de maxima apertura en la que dicha tapa forma un angulo de mas de 95° respecto al marco;providing, the interaction of the lid and frame hinge portions, three locking positions of the lid relative to the frame, a closed position, an intermediate opening position, and a maximum opening position in which said lid forms an angle of more than 95 ° with respect to the frame;
Se entendera que la tapa puede referirse tanto a una tapa que cierre completamente la abertura como a una reja, por ejemplo una reja de sumidero.It will be understood that the lid can refer to both a lid that completely closes the opening and a fence, for example a drain grate.
La posicion de cierre es aquella en la que la tapa queda acoplada al marco y obtura completamente la abertura. La posicion de apertura intermedia es aquella en la que la tapa se encuentra abierta aproximadamente 90° respecto al marco, y por lo tanto en vertical, ya que en todo el documento se entiende que idealmente el marco se encontrara en posicion horizontal aunque se admite su colocation en otras posiciones. La posicion de maxima abertura es aquella en la que la tapa esta totalmente abierta y ya no puede abrirse mas, siendo su angulo de abertura mayor que el de la posicion de apertura intermedia y por lo tanto mayor a 95°. Tlpicamente esta posicion tiene un angulo de abertura de entre 110° y 140° respecto al marco.The closing position is that in which the lid is coupled to the frame and completely seals the opening. The intermediate opening position is that in which the lid is open approximately 90 ° with respect to the frame, and therefore vertically, since in the whole document it is understood that ideally the frame will be in a horizontal position although its colocation in other positions. The maximum opening position is that in which the lid is fully open and can no longer be opened, its opening angle being greater than that of the intermediate opening position and therefore greater than 95 °. Typically this position has an opening angle of between 110 ° and 140 ° with respect to the frame.
La tapa queda articulada respecto al marco mediante el acople de la porcion de bisagra de tapa, que sobresale del perlmetro de la citada tapa, con la porcion de bisagra de marco hueca, que conforma una cavidad en la que dicha porcion de bisagra de tapa se introduce.The lid is articulated with respect to the frame by coupling the lid hinge portion, which protrudes from the perimeter of said lid, with the hollow frame hinge portion, which forms a cavity in which said lid hinge portion is enter.
De un modo novedoso el presente certificado de adicion propone que la tapa incluya ademas un primer brazo protuberante unido a una cara posterior de la tapa incluyendo dicho primer brazo una porcion en voladizo que se extiende quedando elIn a novel way, the present certificate of addition proposes that the cover also includes a first protruding arm attached to a rear face of the cover, said first arm including a cantilevered portion that extends being the

Asl pues de la tapa sobresale un primer brazo que tiene una porcion en voladizo, preferiblemente compuesto del mismo material que el resto de la tapa y fabricado simultaneamente y solidariamente con el resto de la tapa, siendo la tapa y por lo tanto tambien el brazo un solo cuerpo continuo. A modo de ejemplo se propone que dicha tapa y dicho primer brazo esten compuestos de fundicion ductil o de fundicion de grafito esferoidal, ya que este material permite su fabrication enmoldado y a la vez confiere una menor fragilidad en comparacion con la fundicion corriente, y ciertas capacidades elasticas mejoradas.Thus the first arm protrudes from the lid, which has a cantilever portion, preferably composed of the same material as the rest of the lid and manufactured simultaneously and jointly with the rest of the lid, the lid being and therefore also the arm a Only continuous body. By way of example, it is proposed that said cover and said first arm be composed of ductile iron or spheroidal graphite cast iron, since this material allows its fabrication molded and at the same time confers a lower fragility compared to the current foundry, and certain capacities improved elastic.
Estando una porcion del brazo en voladizo, y gracias a las propiedades de elasticidad del material que lo compone en combination con la esbeltez de dicha porcion en voladizo del brazo confiere a dicho brazo de unas propiedades de elasticidad perceptibles. Por lo tanto el extremo distal de la porcion en voladizo, es decir el extremo del brazo mas alejado de la union del brazo con la tapa, admite una deformation y un desplazamiento sensible con respecto a la tapa oponiendo una fuerza elastica frente a dicha deformacion elastica. Por lo tanto dicho brazo actua a modo de muelle que empuja la tapa contra el marco asegurando asl un cierre eficaz, e impidiendo que el paso de personas o vehlculos sobre dicha tapa produzca movimientos, vibraciones o ruidos por el movimiento de la tapa respecto al marco.Being a portion of the cantilever arm, and thanks to the elastic properties of the material that composes it in combination with the slenderness of said cantilever portion of the arm, it gives said arm some perceptible elastic properties. Therefore, the distal end of the cantilever portion, that is to say the end of the arm furthest from the union of the arm with the lid, admits a deformation and a sensitive displacement with respect to the lid opposing an elastic force against said elastic deformation. . Therefore said arm acts as a spring that pushes the cover against the frame thus ensuring an effective closure, and preventing the passage of people or vehicles on said cover produces movements, vibrations or noise by the movement of the cover with respect to the frame .
Segun una realization del perfeccionamiento, la citada interferencia geometrica existente entre el extremo distal del voladizo y el citado apendice de la porcion de bisagra de marco, estando la tapa en posicion cerrada, produce una tension elastica en el brazo que genera con un esfuerzo cuya principal componente es de direction vertical ascendente que se transmite al apendice, estando el marco en posicion horizontal.According to an embodiment of the improvement, the aforementioned geometric interference between the distal end of the overhang and the aforementioned appendix of the frame hinge portion, being the lid in closed position, produces an elastic tension in the arm that generates with an effort whose main The component is of ascending vertical direction that is transmitted to the appendix, the frame being horizontal.
Para generar un esfuerzo en direccion principalmente vertical ascendente, el citado apendice debe estar situado por encima del extremo distal del voladizo, impidiendo su desplazamiento en direccion vertical ascendente para producir su deformacion y generar dicha tension elastica del brazo.To generate an effort in the mainly vertical upward direction, the aforementioned appendix must be located above the distal end of the overhang, preventing its displacement in the upward vertical direction to produce its deformation and generate said elastic tension of the arm.
Estando el apendice por encima, se impide la extraction del brazo, y del resto de la tapa, en direccion vertical ascendente resulta imposible por dicha interferencia geometrica. Por este motivo se propone que el extremo distal del voladizo del brazo seWith the appendix above, the extraction of the arm is prevented, and the rest of the cover, in the vertical upward direction is impossible due to said geometric interference. For this reason it is proposed that the distal end of the cantilever of the arm be

encuentre mas alejado del perimetro de la tapa que el eje de articulacion. Esta caracterlstica permite que al pivotar la tapa alrededor del citado eje de articulacion produciendo su abertura, los elementos situados mas alejados del perimetro de la tapa que dicho eje de articulacion se desplacen en una direction descendente. En este caso el extremo distal del voladizo del brazo desciende alejandose del apendice y permitiendo la citada abertura de la tapa.find farther from the perimeter of the lid than the axis of articulation. This feature allows the pivot to pivot the cover around said articulation axis producing its opening, the elements located farther from the perimeter of the lid that said articulation axis move in a downward direction. In this case the distal end of the cantilever of the arm descends away from the appendix and allowing the aforementioned opening of the lid.
Adicionalmente el perfeccionamiento propuesto contempla que el citado extremo distal del voladizo del brazo tenga al menos una cara coplanar con el extremo retenedor de la portion de bisagra de tapa. De este modo un mismo apendice recto puede interactuar simultaneamente con el extremo retenedor y con el extremo distal del voladizo.Additionally, the proposed improvement contemplates that said distal end of the arm overhang has at least one coplanar face with the retaining end of the lid hinge portion. In this way the same straight appendix can interact simultaneously with the retaining end and with the distal end of the overhang.
Tambien se propone que la porcion de bisagra de tapa se componga de dos paredes distanciadas perpendiculares al eje de articulacion, estando dicha porcion en voladizo del brazo confinada entre dichas dos paredes. De este modo se consigue una construction compacta de la porcion de bisagra de tapa integrando ademas dicho brazo.It is also proposed that the lid hinge portion be composed of two spaced apart walls perpendicular to the articulation axis, said cantilever portion of the arm being confined between said two walls. In this way a compact construction of the lid hinge portion is achieved by also integrating said arm.
De forma adicional se propone que la tapa incluya ademas al menos un segundo brazo protuberante unido a dicha cara posterior de la tapa incluyendo dicho segundo brazo una porcion en voladizo que se extiende quedando, el extremo distal del voladizo, en interferencia geometrica con unos anclajes previstos en el citado marco estando la tapa en position carrada, y quedando el citado al menos un segundo brazo sometido a tension elastica. Dicho al menos un segundo brazo al estar la tapa cerrada queda sometido a tension elastica, generando una fuerza que mantiene la tapa firmemente unida al marco, impidiendo movimientos, vibraciones o ruidos de la tapa y el marco. Para proceder a la apertura de la tapa, habra que aplicar una fuerza ascendente sobre la tapa para producir su pivotacion alrededor del eje de articulacion, y para producir una deformation elastica del citado al menos un segundo brazo que libere su extremo distal de la interferencia geometrica con los citados anclajes del marco. Tlpicamente dicha deformacion de los segundos brazos elasticos se producira en una direccion horizontal.Additionally, it is proposed that the cover also includes at least a second protruding arm attached to said rear face of the cover including said second arm a cantilever portion that extends, the distal end of the cantilever, in geometric interference with anchors provided in said frame with the lid being in carrada position, and the aforementioned being at least a second arm subjected to elastic tension. Said at least a second arm when the lid is closed is subjected to elastic tension, generating a force that keeps the lid firmly attached to the frame, preventing movements, vibrations or noise of the lid and the frame. To proceed with the opening of the lid, an upward force will have to be applied on the lid to produce its pivot around the axis of articulation, and to produce an elastic deformation of said at least one second arm that releases its distal end of the geometric interference with the mentioned frame anchors. Typically said deformation of the second elastic arms will occur in a horizontal direction.
Se entendera que las referencias a posicion geometricas, como por ejemplo paralelo, perpendicular, tangente, vertical, horizontal, etc. admiten desviaciones de hasta ±5° respecto a la posicion teorica definida por dicha nomenclatura.It will be understood that references to geometric position, such as parallel, perpendicular, tangent, vertical, horizontal, etc. they admit deviations of up to ± 5 ° with respect to the theoretical position defined by said nomenclature.

La citada porcion de bisagra de marco 10 tiene forma de caja, disponiendo de dos paredes perpendiculares al eje de articulacion E que se extienden desde el marco 1 y de las que sobresalen los correspondientes gorrones 11, y de una pared paralela al eje de articulacion E que une los extremos de dichas dos paredes encerrando un recinto.Said frame hinge portion 10 has a box shape, having two walls perpendicular to the axis of articulation E that extend from the frame 1 and from which the corresponding pins 11 protrude, and a wall parallel to the axis of articulation E which joins the ends of said two walls enclosing an enclosure.
Sobre dicha pared paralela al eje de articulacion E se emplaza un apendice 15.An appendix 15 is placed on said wall parallel to the axis of articulation E.
La porcion de bisagra de tapa 20 sobresale lateralmente de la propia tapa 2, y se extiende hacia abajo mediante dos paredes laterales enfrentadas y perpendiculares al eje de articulacion E. Sobre las caras exteriores de dichas dos paredes se han previsto unos rebajes que forman dos pistas 21 simetricas.The lid hinge portion 20 protrudes laterally from the lid 2 itself, and extends downwardly by means of two side walls facing and perpendicular to the axis of articulation E. On the outer faces of said two walls, recesses forming two tracks are provided. 21 symmetric
Dichas pistas 21 estan previstas para actuar de levas de los gorrones 11, permitiendo la union y el desplazamiento pivotante de la porcion de bisagra de tapa 20 con la porcion de bisagra de marco 10.Said tracks 21 are provided to act as cams of the bearings 11, allowing the union and pivotal movement of the lid hinge portion 20 with the frame hinge portion 10.
Ademas dicha porcion de bisagra de tapa 20 dispone de un extremo retenedor 22 dispuesto en su extremo mas alejado respecto a la tapa 2, en forma de resalte que es complementario con el citado apendice 15 de la porcion de bisagra de marco 10, quedando el extremo retenedor 22 en contacto con el apendice 15 impidiendo la extraction de la tapa del marco estando la tapa en position cerrada. El citado extremo retenedor 22 se compone en la presente realization de dos extremo retenedores simetricos, estando la porcion de bisagra de tapa 20 compuesta de dos paredes paralelas distanciadas, cada una dotada de una pista 21 y de un extremo retenedor 22.Furthermore, said lid hinge portion 20 has a retaining end 22 disposed at its furthest end with respect to the lid 2, in the form of a shoulder which is complementary to the aforementioned appendix 15 of the frame hinge portion 10, the end being retainer 22 in contact with appendix 15 preventing removal of the frame cover while the lid is in the closed position. The aforementioned retaining end 22 is composed in the present embodiment of two symmetrical retaining ends, the lid hinge portion 20 being composed of two spaced parallel walls, each provided with a track 21 and a retaining end 22.
La tapa 2 integra ademas un primer brazo elastico unido a su cara posterior. Dicho primer brazo esta compuesto del mismo material que la tapa, y esta fabricado al mismo tiempo que la misma, siendo el primer brazo elastico y la tapa 2 solidarios.The cover 2 also integrates a first elastic arm attached to its rear face. Said first arm is composed of the same material as the lid, and is manufactured at the same time as the lid, the first elastic arm and the lid 2 being integral.
Dicho primer brazo elastico dispondra de una porcion en voladizo cuya esbeltez le conferira propiedades elasticas perceptibles, permitiendo de este modo actuar, con ciertas limitaciones, a modo de muelle.Said first elastic arm will have a cantilever portion whose slenderness will confer perceptible elastic properties, thus allowing it to act, with certain limitations, as a spring.
Dicho primer brazo elastico dispone de un extremo distal (el extremo mas alejado de su union con la tapa 2) estando dicho extremo distal dispuesto en una posicion adyacente al extremo retenedor 22, concretamente dicho extremo distal se emplaza entre los dos extremos retenedores 22 simetricos antes descritos, quedando dicha porcion en voladizo del primer brazo elastico al menos parcialmente emplazada entre las dos paredes simetricas que componen la porcion de bisagra de tapa 20.Said first elastic arm has a distal end (the end furthest from its union with the cover 2) said distal end being disposed in a position adjacent to the retaining end 22, namely said distal end is located between the two symmetrical retaining ends 22 before described, said cantilever portion of the first elastic arm being at least partially located between the two symmetrical walls that make up the lid hinge portion 20.
El citado extremo distal tiene al menos una cara coplanar con el extremo retenedor 22 de la porcion de bisagra de tapa 20, de modo que tanto los dos extremos retenedoresThe said distal end has at least one coplanar face with the retaining end 22 of the lid hinge portion 20, so that both the two retaining ends

22 simetricos como el extremo distal del primer brazo elastico entran en contacto con el apendice 15 de la porcion de bisagra de marco 10 estando la tapa en posicion cerrada, produciendo una deformacion elastica del primer brazo elastico generando una tension que mantiene la porcion de bisagra de tapa 20 presionada contra la porcion de bisagra de marco 10.22 symmetrical like the distal end of the first elastic arm come into contact with the appendix 15 of the frame hinge portion 10 while the lid is in the closed position, producing an elastic deformation of the first elastic arm generating a tension that maintains the hinge portion of cover 20 pressed against the frame hinge portion 10.
Dicho extremo distal se propone que se encuentre mas alejado del perlmetro de la tapa que el eje de articulacion E. Esta caracterlstica permite que, al abrir la tapa, todos los elementos dispuestos mas alejados de la tapa 2 que dicho eje de articulacion E se desplacen en una direction descendente. De este modo el extremo distal del primer brazo elastico se separara del apendice 15 permitiendo la apertura de la tapa 2.Said distal end is proposed to be farther from the perimeter of the lid than the articulation axis E. This feature allows, when opening the lid, all the elements disposed farther from the lid 2 than said articulation axis E to move in a downward direction. In this way the distal end of the first elastic arm will be separated from the appendix 15 allowing the opening of the lid 2.
El contacto entre el extremo distal y el apendice 15 se produce en un plano horizontal o casi horizontal, admitiendose que dicho plano de contacto pueda estar inclinado ± 45° respecto a la posicion horizontal. Esta posicion del plano de contacto permite generar, por causa de la tension elastica, un esfuerzo cuya principal componente es de direccion vertical.The contact between the distal end and the appendix 15 occurs in a horizontal or almost horizontal plane, admitting that said contact plane can be inclined ± 45 ° with respect to the horizontal position. This position of the contact plane allows to generate, due to elastic tension, an effort whose main component is of vertical direction.
En la presente realization se incluyen ademas dos segundos brazos elasticos unidos a la cara posterior de la tapa 2, dispuestos simetricamente. Cada uno de dichos segundos brazos elasticos dispone de una union con la tapa, de una porcion esbelta en voladizo y de un extremo distal confiriendo a dicho brazo propiedades elasticas perceptibles similares a las del primer brazo elastico. Cada uno de los extremos distales de los segundos brazos elasticos esta previsto para ser acoplado a un anclaje previsto en el marco 1 produciendo una deformacion elastica de dicho segundo brazo elastico y por lo tanto creandose una tension elastica que empuja la tapa contra el marco.The present embodiment also includes two second elastic arms attached to the rear face of the cover 2, arranged symmetrically. Each of said second elastic arms has a joint with the lid, a slender cantilever portion and a distal end conferring said elastic properties on the arm similar to those of the first elastic arm. Each of the distal ends of the second elastic arms is provided to be coupled to an anchor provided in the frame 1 producing an elastic deformation of said second elastic arm and therefore creating an elastic tension that pushes the cover against the frame.
Los extremos distales de dichos segundos brazos elasticos no sobresalen del perlmetro definido por la tapa 2, por lo tanto al abrir la tapa 2 dichos extremos distales tambien se desplazan en direccion ascendente junto con la tapa 2. Para producir la liberation de dichos extremos distales de los respectivos anclajes mediante dicho desplazamiento ascendente, se requiere que la deformacion elastica de los segundos brazos se produzca en una direccion paralela a la tapa 2, al contrario que la deformacion del primer brazo que se propone que sea en una direccion perpendicular a la tapa 2.The distal ends of said second elastic arms do not protrude from the perimeter defined by the cover 2, therefore when opening the cover 2 said distal ends also move upwards together with the cover 2. To produce the release of said distal ends of the respective anchors by means of said upward displacement, it is required that the elastic deformation of the second arms occurs in a direction parallel to the cover 2, unlike the deformation of the first arm that is proposed to be in a direction perpendicular to the cover 2 .
La combination de la fuerza elastica ejercida sobre la tapa 2 por los primer y segundos brazos retiene la tapa 2 firmemente acoplada contra el marco 1, evitando movimientos, ruidos o vibraciones.The combination of the elastic force exerted on the cover 2 by the first and second arms retains the cover 2 firmly coupled against the frame 1, avoiding movements, noises or vibrations.
