Descripción de la invenciónDescription of the invention

La bisagra para escaleras de tijera y otras aplicaciones objeto de la presente invención, además de estar provista de un tope de apertura mediante planchas de metal que apoyan de canto, incorpora en sus dos palas rectangulares de montaje a ambos lados de la escalera, de unos tornillos salientes hacia el interior, cuyos tornillos quedan solidariamente fijados por su cabeza mediante soldadura, remachado o cualquier otro medio, de forma que, para realizar su montaje en los dos lados de la escalera (normalmente de madera), con solo proceder a realizar en los puntos requeridos de la misma unos orificios pasantes, la bisagra se aplica a la escalera introduciendo los tornillos solidariamente fijados a la propia bisagra, fijándola mediante tuercas en los extremos saliente de los tornillos en las partes internas de los puntos de aplicación de las bisagras.The hinge for scissor stairs and others applications object of the present invention, besides being provided with an opening stop by metal plates that They support singing, incorporates in its two rectangular mounting blades  on both sides of the stairs, of some projecting screws towards the interior, whose screws are fixedly fixed by its head by welding, riveting or any other means, of so that, for mounting on both sides of the stairs (usually made of wood), just proceed to perform in the points through holes are required, the hinge is applied  to the ladder by introducing the screws fixedly attached to the hinge itself, fixing it with nuts at the ends protrusion of the screws in the internal parts of the points of application of hinges.

Las dos palas que conforman la bisagra propiamente dicha, se montan articuladamente entre si por un acodamiento superior y junto a la parte baja de las mencionadas palas, se incorporan dos piezas unidas entre sí y fijadas a su vez cada una de ellas, a las palas de modo que al producirse la apertura de la escalera, la bisagra mediante sus palas abiertas, tira de las piezas en forma de biela, cuya extensión limita la apertura de la bisagra y consecuentemente de la escalera de tijera.The two blades that make up the hinge proper, they are mounted articulately to each other by a upper bending and next to the lower part of those mentioned shovels, two pieces joined together and fixed in turn each of them, to the blades so that when opening occurs from the ladder, the hinge with its open blades, pulls the connecting rod-shaped pieces, the extent of which limits the opening of the hinge and consequently the scissor ladder.

Las dos piezas en forma de biela por la parte alta de la articulación entre ellas mismas en el centro entre las dos palas, disponen de unos salientes en los que se ha practicado un ligero doblado, para que el material de las dos bielas que se disponen en posición continua una de otra, al realizarse el plegado en el sentido de acercamiento mutuo, al alcanzar la escalera su máxima apertura útil, actúen de tope que regula la apertura de la escalera.The two rod-shaped parts on the side high joint between themselves in the center between two blades, have some protrusions in which it has been practiced a slight bent, so that the material of the two connecting rods is they have a continuous position of each other, when folding in the sense of mutual approach, upon reaching the ladder its maximum useful opening, act as a stop that regulates the opening of the stairs.
