Antecedentes de la invención Background of the invention

En las bisagras del tipo indicado el pasador que relaciona las palas va montado en los casquillos sin posibilidad de deslizamiento longitudinal respecto de los mismos. Generalmente el pasador es solidario de uno de los casquillos. 15 On the hinges of the type indicated the pin that relates the blades is mounted on the bushings without the possibility of longitudinal sliding with respect to them. Generally the pin is integral with one of the bushes. fifteen

Con esta constitución, cuando es necesario desmontar una hoja de puerta o ventana, es necesario elevarla hasta lograr que el pasador quede fuera del casquillo no solidario de dicho pasador. Cuando se quiere volver a montar la hoja, como el montaje de la misma requiere la disposición de al menos dos bisagras, es necesario montar la mismo tiempo ambas bisagras, lo 20 cual exige enfrentar al mismo tiempo los pasadores y casquillos de las dos bisagras. Esta operación se complica cuando la hoja es pesada y su montaje se efectúa con tres o más bisagras. With this constitution, when it is necessary to disassemble a door or window leaf, it is necessary to raise it until the pin is outside the non-integral bushing of said pin. When you want to reassemble the sheet, as the assembly of the same requires the provision of at least two hinges, it is necessary to assemble both hinges at the same time, which requires facing both the pins and bushings of the two hinges. This operation is complicated when the blade is heavy and its assembly is carried out with three or more hinges.

Descripción de la invención 25 Description of the invention

La presente invención tiene por objeto proporcionar una bisagra para el montaje de puertas y ventanas, del tipo inicialmente indicado, constituida de modo que permita extraer e introducir fácilmente el pasador a través de los casquillos, lo cual permitirá separar y unir las dos palas de las bisagras, facilitando con ello tanto el desmontaje como el montaje de las hojas de una 30 puerta o ventana. The present invention aims to provide a hinge for the assembly of doors and windows, of the type initially indicated, constituted so as to allow the pin to be easily removed and inserted through the bushings, which will allow the two blades of the two to be separated and joined. hinges, thereby facilitating both disassembly and assembly of the leaves of a door or window.

La bisagra de la invención dispone además de medios que impiden la salida accidental del pasador de los casquillos de las palas, una vez introducido hasta su posición de montaje. The hinge of the invention also has means that prevent the accidental exit of the pin from the blades of the blades, once it has been introduced to its mounting position.

En la bisagra de la invención el pasador es de diámetro ligeramente menor que el interno de los casquillos de las palas, de modo que sin que existan holguras apreciables entre pasador y casquillos, dicho pasador sea fácilmente deslizable a través de los casquillos. In the hinge of the invention, the pin is slightly smaller in diameter than the internal of the blade bushes, so that without appreciable gaps between pin and bushes, said pin is easily slidable through the bushes.

De acuerdo con la invención el pasador y uno de los casquillos, al menos, dispone en sus 40 superficies enfrentables de conformaciones macho y hembra complementarias que son encastrables entre sí por presión, al alcanzar posiciones axiales coincidentes, en las que constituyen un medio de enclavamiento que impide el deslizamiento accidental del pasador respecto de los casquillos. In accordance with the invention, the pin and one of the bushings, at least, have in their 40 facing surfaces complementary male and female conformations that are recessed together by pressure, upon reaching coincident axial positions, in which they constitute a locking means. which prevents accidental sliding of the pin with respect to the bushings.

Según una posible forma de ejecución, las conformaciones macho y hembra son elásticamente retraíbles por presión. According to a possible embodiment, the male and female conformations are elastically retractable by pressure.

En una forma preferida de ejecución las conformaciones complementarias consisten en una garganta, y en un resalte anular que presentan el pasador y uno de los casquillos, definiendo 50 las conformaciones macho y hembra que quedan situadas en posiciones coincidentes, al introducir el pasador en los casquillos hasta la posición de funcionamiento. In a preferred embodiment, the complementary conformations consist of a throat, and an annular projection that the pin and one of the bushes have, defining 50 the male and female conformations that are located in coincident positions, when the pin is inserted into the bushes. to the operating position.

Por ejemplo, el pasador puede presentar una garganta periférica, cerca de uno de sus extremos, y uno de los casquillos un resalte anular interno, cerca de su base exterior. El pasador puede ir rematado en el extremo opuesto en una cabeza que puede estar formada sobre el mismo pasador o constituir una pieza independiente, fijable al pasador por ejemplo mediante roscado. 5 For example, the pin may have a peripheral throat, near one of its ends, and one of the bushings has an internal annular shoulder, near its outer base. The pin can be finished off at the opposite end in a head that can be formed on the same pin or constitute an independent piece, fixable to the pin for example by threading. 5

De este modo, el acoplamiento entre el pasador y casquillos de las palas se consigue mediante las conformaciones macho y hembra complementarias, pudiendo las conformaciones macho adoptar forma de nervio continuo o de resaltes discontinuos, en forma de salientes radiales retráctiles, de tipo “Jack”. 10 In this way, the coupling between the pin and bushes of the blades is achieved by the complementary male and female conformations, the male conformations being able to take the form of a continuous nerve or of discontinuous projections, in the form of retractable radial projections, of the "Jack" type. . 10

Descripción detallada de un modo de realización 20 Detailed description of one embodiment 20

La constitución y ventajas de la bisagra de la invención se comprenderán mejor con la siguiente descripción del ejemplo de realización, mostrado en los dibujos adjuntos. The constitution and advantages of the hinge of the invention will be better understood with the following description of the exemplary embodiment, shown in the accompanying drawings.

En la figura 1 se muestra una bisagra compuesta por dos palas (1 y 2) portadoras de otros tantos casquillos cilíndricos alineados, uno inferior (3) y otro superior (4). 25 Figure 1 shows a hinge composed of two blades (1 and 2) carrying as many aligned cylindrical bushings, one lower (3) and one upper (4). 25

Las palas (1 y 2) disponen además de orificios (5) para el paso de tornillos de fijación a la hoja de una puerta o ventana y al marco de la misma. The blades (1 and 2) also have holes (5) for the passage of fixing screws to the leaf of a door or window and to the frame thereof.

El casquillo superior (4) queda superpuesto en posición coaxial sobre el casquillo inferior (3). A través de los dos casquillos se introduce un pasador (6) que sirve como medio de unión y articulación entre las dos palas. 30 The upper bushing (4) is superimposed in a coaxial position on the lower bushing (3). Through the two bushings a pin (6) is introduced that serves as a means of connection and articulation between the two blades. 30

El pasador (6) es de diámetro ligeramente menor que el interno de los casquillos (3 y 4), sin que exista holgura apreciable entre los mismos, pero de modo que permita el deslizamiento del pasador respecto a los casquillos. The pin (6) is slightly smaller in diameter than the internal of the bushings (3 and 4), without appreciable clearance between them, but in a way that allows the pin to slide with respect to the bushings.

El pasador (6) y el casquillo superior (4) disponen de medios complementarios macho y hembra de enclavamiento. Estos medios consisten en un canal anular (7) que presenta el 35 pasador (6) cerca de uno de sus extremos, y en un resalte (8) que sobresale de la superficie interna del casquillo superior (4). Este resalte puede ser continuo, en forma de nervio anular, o discontinuo, en forma de resaltes retráctiles, tipo “Jack”. The pin (6) and the upper bushing (4) have complementary male and female interlocking means. These means consist of an annular channel (7) having the pin (6) near one of its ends, and a shoulder (8) protruding from the inner surface of the upper bushing (4). This projection can be continuous, in the form of an annular nerve, or discontinuous, in the form of retractable projections, "Jack" type.

En el extremo inferior el pasador (6) queda rematado en una cabeza (9) de diámetro mayor que el interno de los casquillos (3 y 4) y que servirá como tope que limite la penetración del pasador 40 en los casquillos de las palas. At the lower end, the pin (6) is finished off in a head (9) of greater diameter than the internal of the bushings (3 and 4) and which will serve as a stop that limits the penetration of the pin 40 in the paddle bushings.

Con la constitución comentada, el pasador (6) puede introducirse mediante una ligera presión a través de los casquillos (3 y 4) alineados, hasta lograr la retracción de los salientes (8), por el extremo (10) del pasador, y su recuperación una vez que ha pasado dicho extremo de los salientes (8), para su acoplamiento sobre la garganta (7), impidiendo así la salida accidental del 45 pasador. Para la extracción del pasador se actuará de forma contraria, por ejemplo traccionando desde su cabeza (9). With the constitution mentioned, the pin (6) can be introduced by a slight pressure through the bushes (3 and 4) aligned, until retraction of the projections (8), by the end (10) of the pin, and its recovery once said end of the projections (8) has passed, for coupling on the throat (7), thus preventing the accidental exit of the pin. To remove the pin, the opposite will be done, for example by pulling from its head (9).

De este modo, para desmontar una puerta montada con las bisagras de la invención, será suficiente extraer los pasadores de todas las bisagras, operación que puede ser realizada por una sola persona, sin uso de herramientas y sin necesidad de tener que elevar la puerta, como se requiere con las bisagras tradicionales. Thus, to disassemble a door mounted with the hinges of the invention, it will be sufficient to remove the pins from all the hinges, an operation that can be performed by a single person, without the use of tools and without having to raise the door, as required with traditional hinges.

El pasador (6) se introducirá desde abajo o desde arriba, dependiendo de cómo se monta la 5 bisagra. The pin (6) will be inserted from below or from above, depending on how the hinge is mounted.

El casquillo superior (4) puede presentar su base externa (11) cerrada. The upper bushing (4) can have its external base (11) closed.

La cabeza (9) del pasador puede formar parte del mismo, constituyendo con él una sola pieza, o bien ser independiente, según se muestra en la figura (2). La cabeza (9) puede disponer de una espiga (12) roscada y el pasador (6) de un taladro axial (13), también roscado, para su 10 fijación mutua. The head (9) of the pin can be part of it, constituting with it a single piece, or be independent, as shown in figure (2). The head (9) may have a threaded pin (12) and the pin (6) of an axial bore (13), also threaded, for mutual fixing.
