DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE.DESCRIPTION OF A PREFERRED EMBODIMENT.
A la vista de las comentadas figuras y de acuerdo con la numeración adoptada, podemos observar como los pestillos 1 de golpe convencionales son susceptibles de adoptar una única posición, de forma que el extremo biselado 2 del pestillo al estar solicitado por un resorte 3 queda sobresaliendo respecto del testero o cabecera de la cerradura, permitiendo que en el cierre de la puerta 4 al topar el pestillo respecto de su zona biselada 2 con el elemento 5 relativo al elemento 6 en el que se presenta elIn view of the aforementioned figures and in accordance with the numbering adopted, we can see how conventional blow latches 1 are capable of adopting a single position, so that the beveled end 2 of the latch when requested by a spring 3 is protruding with respect to the end of the lock or headboard, allowing the latch of the door 4 to bump the latch with respect to its beveled area 2 with the element 5 relative to the element 6 in which the

Así, el cuerpo 6 en el que se haya el cerradero 7 de enclavamiento del pestillo 1 , alojado para su guiado en el correspondiente habitáculo 11 , presenta el elemento 5 con el extremo de tope del pestillo 1 ligeramente curvo para facilitar su retraimiento y su enclavamiento en el cerradero 7.Thus, the body 6 in which the locking latch 7 of the latch 1, housed for guidance in the corresponding compartment 11, has the element 5 with the stop end of the latch 1 slightly curved to facilitate its retraction and interlocking on the lock 7.
Con esta configuración se presenta el inconveniente de que en el espacio que queda entre la cabecera o testero de la cerradura y el cerradero, el pestillo 1 presenta una superficie biselada hacia el exterior, de manera que si se actúa por el exterior con cierta habilidad sobre él, con una simple tarjeta 8 o cualquier otro elemento haciendo presión, se llega a provocar su retraimiento por la descomposición de fuerzas que se produce, venciendo la presión del resorte 3 y abriéndose la puerta.With this configuration, the disadvantage arises that in the space between the headboard or the head of the lock and the lock, the latch 1 has a beveled surface towards the outside, so that if it is operated outside with a certain ability to he, with a simple card 8 or any other element under pressure, is able to cause its withdrawal by the decomposition of forces that occurs, overcoming the pressure of the spring 3 and opening the door.
Con objeto de solventar este inconveniente en la presente memoria se describe un pestillo 9 perfeccionado susceptible de adoptar dos posiciones diferentes, según se encuentra en posición para el cierre de la puerta, esto es, cuando la puerta portadora de la cerradura esté abierta y cuando el pestillo perfeccionado se encuentre enclavado en el cerradero.In order to solve this drawback, an improved latch 9 capable of adopting two different positions is described, as it is in position for closing the door, that is, when the door carrying the lock is open and when the perfected latch is locked in the strike.
Así, en la figura 3 de los diseños se observa como el pestillo 9 perfeccionado se encuentra con su extremo biselado sobresaliendo del ras del cabecero o testero de la cerradura de la puerta 4 con el lado interno del tramo 2 biselado enrasado con el cabecero o testero, de manera que al cerrar la puerta el pestillo 9 topa con el elemento 5 del cuerpo 6 de cierre, generalmente un marco, retrayéndose para posicionarse en el cerradero 7 en cuyo movimiento el pestillo perfeccionado tiene un mayor recorrido hacia el exterior tal como se observan las figuras 4 y 5 de los diseños.Thus, in figure 3 of the designs it is observed how the improved latch 9 is found with its beveled end protruding from the head of the headboard or front of the door lock 4 with the inner side of the bevelled section 2 flush with the headboard or headboard , so that when the door is closed, the latch 9 encounters the element 5 of the closing body 6, generally a frame, retracting to position itself in the striker 7 in whose movement the improved latch has a greater outward travel as observed Figures 4 and 5 of the designs.
Por otra parte, en la figura 5 de los diseños se observa como el pestillo 9 queda enclavado en el cerradero 7 de manera que en el espacio comprendido entre el cabecero o testero de la cerradura de la puerta 4 y el cerradero, el pestillo 9 presenta una superficie 10 totalmente plana en esta ejecución, si bien podrá adoptar cualquier otra configuración que impida su manipulación.On the other hand, in figure 5 of the designs it is observed how the latch 9 is locked in the striker 7 so that in the space between the headboard or headboard of the lock of the door 4 and the striker, the latch 9 presents a completely flat surface 10 in this embodiment, although it may adopt any other configuration that prevents its manipulation.
De esta forma, al quedar enclavado el pestillo 9, tal como se representa en la figura 5 de los diseños, si se trata de actuar sobre el pestillo con cualquier elemento, tai como una tarjeta 8 u otro cualquiera alIn this way, when latch 9 is locked, as shown in figure 5 of the designs, if it is about acting on the latch with any element, such as a card 8 or any other
