Abstract

Un montaje de cerradura incluye un tapon con una chaveta, pines primarios (188) alineados con la chaveta, una barra lateral (222), pines secundarios (204) adyacentes a la chaveta y al menos un elemento de control de barra lateral suplementario para controlar el movimiento de la barra lateral. Una llave en bruto tiene una hoja de llave con un borde superior primario (118) para recibir mordiscos primarios (120) para controlar los pines primarios (188), una nervadura (132) para recibir mordiscos secundarios (136) para controlar los pines secundarios, y al menos un pin de lanzadera (138). El pin de lanzadera (138) se acopla a una arista de multiples niveles (164) dentro de la chaveta para mover el pin de lanzadera (138) de una posicion retraida a una posicion extendida en donde un extremo del pin de lanzadera (138) acciona el elemento de control de barra lateral suplementario.
