Security lock for doors has spring through which auxiliary slide pulls or pushes tilting piece when moving to maximum extraction position or retraction position, respectively

摘要

An auxiliary slide (9) pulls a tilting piece (15) through a spring (18) when moving to a maximum extraction position in which the auxiliary slide blocks a closing slide (1) from moving to a retraction position. Moving the auxiliary slide to the retraction position pushes the tilting piece upright through the spring and allows the closing slide to freely retract.
