Abstract
Catenaccio ferma-porta per porte e cancelli a doppia anta, applicabile al montante esterno dell'anta priva di serratura, costituito da un profilato metallico a lamina piegata ad "L" onde creare due ali ancorabili al montante esterno dell'anta priva di serratura, tra dette due ali essendo montato un catenaccio cilindrico, liberamente guidato tra le ali e cavallotti di ritegno, in modo da poter fuoriuscire parzialmente verso il basso per inserirsi in un corrispondente foro ricavato nel pavimento o terreno, detto chiavistello essendo racchiuso entro almeno una molla cilindrica di richiamo e sottoposto a traslazione, con caricamento di detta molla, da due elementi astiformi apribili-chiudibili a compasso e incernierati, con un estremo, a una di dette ali e con l'altro estremo in testa a detto catenaccio, così da consentire ad ogni chiusura dell'anta con serratura, il divaricamento di dette aste e quindi la fuoriuscita del chiavistello di ancoraggio al pavimento e, all'apertura della stessa anta, l'automatico richiamo di detto catenaccio ad opera di detta molla previamente caricata.Door-locking bolt for double-leaf doors and gates, applicable to the external upright of the door without lock, consisting of a metal profile with "L" folded foil to create two wings anchored to the external upright of the door without lock, between said two wings being mounted a cylindrical bolt, freely guided between the wings and retaining brackets, so as to be able to partially come out downwards to fit into a corresponding hole in the floor or ground, said bolt being enclosed within at least one cylindrical spring of return and subjected to translation, with loading of said spring, by two rod-shaped, lockable, compass-shaped elements hinged, with one end, to one of said wings and with the other end at the head of said bolt, so as to allow each closure of the door with lock, the spreading of said rods and therefore the exit of the anchor bolt to the floor and, when the same is opened on the leaf, the automatic return of said deadbolt by said previously loaded spring.
