摘要

Improvements in the locking mechanisms of the movable latches of a door, of application in the assemblies formed of two facing doors, equipped with respective locks and hinged on the same side, with a twist in the same sense, in which the interior is ordinary and the outside is latticed for protection, and in which the opening from within is only feasible previous coupling at will of their locks for simultaneous operation, characterized because the outer door has a horizontal rod equipped with a latch and a push spring, which it corresponds longitudinally with a slot of the fixed frame in its hinged upright, having in the same upright another rod in perpendicularity with the previous one and provided with a spring that pushes it against the mobile hinge of the inner door, corresponding longitudinally with a rear slot of the same frame, said hinge having a projection that, in the open position of the door the inner part tightens the rod in question, so that both doors being closed, the respective rods are in forward position, that is, the latch of the outer door remaining applied, and in the case of being opened the inner door, its rod is pushed by the projection of the hinge intercepting an eventual setback formed from the rod of the outer door, while when both doors are opened together, the rod of the outer door is retracted by the lock itself to enable the opening.
