El dispositivo objeto de la presente invención presenta como características descollantes la facilidad de montaje y desmontaje del acoplamiento de vigas y la gran seguridad del dispositivo de conexión, puesto que de modo natural no se pueden desacoplar ni caer los elementos de viga, ya que en caso de caída de uno de los elementos de viga, éste quedará simplemente suspendido del enganche. Esta posibilidad de suspensión se utiliza también en el desmontaje, puesto que el elemento que se desea desmontar puede quedar en una primera fase simplemente suspendido del gatillo de enganche del dispositivo de conexión.The device object of the present invention presents as easy features the ease of assembly and disassembly of the beam coupling and the great safety of connection device, since naturally they cannot be decouple or drop the beam elements, since in case of falling one of the beam elements, this will be simply suspended of the hitch. This possibility of suspension is also used in disassembly, since the element to be disassembled can stay in a first phase simply suspended from the trigger of connection device hitch.

De modo esencial, para cumplir su función el dispositivo objeto de la presente invención comprende en un extremo de la viga un gatillo de forma compleja basculante alrededor de un eje interno, con tope de desplazamiento en giro en el interior del propio elemento de viga, con un perfil externo conjugable con el elemento del otro extremo de la viga para producir su fácil apertura y con una zona de apoyo arqueada con centro de curvatura coincidente en el centro de giro del gatillo, por lo que proporciona una posición estable sin posibilidad de par de giro para que se pueda desprender un elemento de viga. El dispositivo se complementa con un pasador fijado en el otro extremo del elemento de viga, sujeto mediante piezas dispuestas sensiblemente en forma de ángulo diedro, en las que un brazo sirve para el acoplamiento de un pasador horizontal de enganche con el gatillo del extremo opuesto del elemento de viga en prolongación mientras que el otro brazo forma una superficie de apoyo para los laterales el elemento de viga en prolongación. De esta manera se consigue una función de tope vertical por apoyo sobre dichas superficies, lo cual no permite el desplazamiento vertical de un elemento de viga con respecto al siguiente mientras que se consigue también el tope axial por la conjugación de la acción del pasador horizontal de un extremo con el gatillo de retención del extremo del elemento de viga dispuesto en oposición.Essentially, to fulfill its function the device object of the present invention comprises at one end of the beam a trigger of complex tilting shape around a internal shaft, with rotating travel stop inside the own beam element, with an external profile conjugable with the element at the other end of the beam to produce its easy opening and with an arched support zone with a center of coincidence of curvature in the center of rotation of the trigger, so it provides a stable position without the possibility of turning torque so that you can detach a beam element. The device is complemented with a pin fixed on the other end of the beam element, attached by pieces arranged substantially in the form of a dihedral angle, in which an arm is used for coupling a pin horizontal hitch with the trigger on the opposite end of the extension beam element while the other arm forms a support surface for the sides the beam element in extension. This way a stop function is achieved vertical by support on these surfaces, which does not allow vertical displacement of a beam element with respect to the following while the axial stop is also achieved by the conjugation of the action of the horizontal pin of one end with the Trigger of retention of the end of the beam element arranged in opposition.
