Presenta el perno de fijación objeto de esta invención, como característica esencial, el hecho de que al colocarse se bloquea él mismo de manera inmediata sin necesidad de efectuar operación o maniobra alguna en la parte posterior del lugar donde se está colocando. Ello le confiere la importante particularidad del autobloqueo.It presents the fixing bolt object of this invention, as an essential feature, the fact that at putting himself locks himself immediately without needing carry out any operation or maneuver at the back of the place Where it is being placed. This gives the important particularity of the self-locking.

Generalmente, en la actualidad, al unir dos o más placas mediante pernos que las atraviesan a través de orificios previamente practicados en las mismas, se requiere, para su fijación, la colocación por la parte posterior de una tuerca, y para mayor seguridad una contratuerca, lo que impide que, de forma accidental, el perno pueda desprenderse.Generally, at present, by joining two or more plates by bolts that pass through holes previously practiced in them, is required, for fixing, placement by the back of a nut, and for greater security a locknut, which prevents, so accidental, the bolt can come off.

La necesidad de colocar y mantener retenida la tuerca posterior para fijarla por roscado adecuadamente, obliga a que un operario la sostenga, accediendo para ello a ese lugar, lo que en ciertas ocasiones, resulta difícil, por causa de la inaccesibilidad de ese lugar posterior, o bien por las dimensiones de las placas que se están fijando.The need to place and hold the rear nut to fix it by threaded properly, forces for an operator to hold it, by accessing that place, that on certain occasions, it is difficult, because of the inaccessibility of that later place, or because of the dimensions of the plates that are being fixed.

Hasta el presente se ha intentado solventar estos inconvenientes prácticos con la utilización de diversos tipos de pernos, la mayoría de los cuales requiere sostener las mencionadas tuerca y contratuerca mientras se procede al apriete por roscado del conjunto.Until now, attempts have been made to solve these practical inconveniences with the use of various types of bolts, most of which require holding the mentioned nut and locknut while tightening by threaded assembly.

El perno de fijación, provisto de un sistema de autobloqueo, objeto de esta invención, ofrece una solución práctica y efectiva a la problemática antes descrita, al presentar un elemento útil para llevar a cabo toda instalación en que han de fijarse dos o más placas entre sí, así como placas con paneles aislantes intermedios u otros dispositivos de construcción, recubrimiento y/o aislamiento, de fácil aplicación por parte de los operarios especializados en este tipo de instalaciones.The fixing bolt, provided with a system of Self-locking, object of this invention, offers a practical solution and effective to the problem described above, when presenting a useful element to carry out any installation in which they have to fix two or more plates together, as well as panels with panels intermediate insulators or other construction devices, coating and / or insulation, easy to apply by operators specialized in this type of facilities.

Esta facilidad práctica de utilización está basada en el hecho de que, una vez colocada por el extremo posterior del perno una arandela al efecto diseñada, no será preciso mantenerla sujeta, ya que el propio perno, al girarlo en una acción de roscado, provocará el autobloqueo del conjunto.This practical ease of use is based on the fact that, once placed at the rear end of the bolt a washer designed for this purpose, it will not be necessary keep it fastened, since the bolt itself, when turning it into an action Threading will cause the self-locking of the assembly.

De acuerdo con estos dibujos, el perno de fijación con sistema de autobloqueo, objeto de esta invención, consiste en un perno o vástago metálico propiamente dicho (1), preferentemente de acero y de forma cilíndrica, provisto de un fileteado de rosca en toda su longitud excepto en un extremo, el cual será sin fileteado y de diámetro inferior al de la rosca para facilitar la operación de sujección del conjunto y operación por ejemplo con la utilización de la mordaza de un taladro. El diámetro de este perno es pequeño con relación a su longitud, mostrando la apariencia de un espárrago roscado, siendo su longitud variable, de acuerdo con el grosor total del conjunto de placas u otros elementos similares que deban unirse y fijarse.According to these drawings, the bolt of fixing with self-locking system, object of this invention, consists of a bolt or metal rod itself (1), preferably of steel and cylindrical shape, provided with a threaded thread over its entire length except at one end, the which will be without filleting and of a smaller diameter than the thread for facilitate the operation of securing the assembly and operation by example with the use of the jaw of a drill. The diameter of this bolt is small in relation to its length, showing the appearance of a threaded stud, its variable length being, of according to the total thickness of the set of plates or other elements similar that must be joined and fixed.

Este perno (1) está provisto, en uno de sus extremos, de una cabeza cónica circular (2), para facilitar la alineación del conjunto con los orificios de las placas, o incluso de una cabeza de corte tipo broca para realizar dichos orificios en caso de que éstos no existan, a cuya cara inferior queda solidarizado un resorte espiral plano (3) de desarrollo diametral creciente.This bolt (1) is provided, in one of its ends, of a circular conical head (2), to facilitate the alignment of the assembly with the holes in the plates, or even of a drill-type cutting head to make said holes in if these do not exist, whose lower face is solidarity a flat spiral spring (3) of diametral development growing.

Éste perno puede presentar puntos debilitados para, en caso de que no se requiera el desmontaje del perno de fijación objeto de ésta invención, se pueda romper el vástago por cizallamiento, de modo que del conjunto no sobresalga dicho vástago, tal como re representa en la Figura 4. El perno o vástago (1), la cabeza (2) y el resorte espiral plano (3) forman un sólo conjunto indivisible. Se completa el conjunto con una arandela plana circular (4), la cual presenta en un lado de su parte central un resalte cilíndrico y regruesado (5), de diámetro coincidente con el de los orificios que debe practicarse en las placas a unir y fijar. En el otro lado, la arandela (4) figura un núcleo prismático hexagonal (6), de anchura menor que el resalte (5), con las caras planeadas con el fin de facilitar la sujección de la arandela en el momento de la compresión del resorte, con una llave o dispositivo afín a tal efecto, la cual está provista de un orificio roscado interiormente, para su disposición sobre el perno (1), roscado sobre el mismo.This bolt may have weakened points. for, in case the disassembly of the bolt is not required fixing object of this invention, the rod can be broken by shear, so that the rod does not protrude from the assembly, as shown in Figure 4. The bolt or rod (1), the head (2) and the flat spiral spring (3) form a single set indivisible. The set is completed with a circular flat washer (4), which has a highlight on one side of its central part cylindrical and thickened (5), with a diameter coinciding with that of the holes to be made in the plates to be joined and fixed. At On the other hand, the washer (4) contains a hexagonal prismatic core (6), smaller than the protrusion (5), with the faces planned in order to facilitate the fastening of the washer at the time of compression of the spring, with a key or device related to such effect, which is provided with an internally threaded hole, for its arrangement on the bolt (1), threaded on it.
