<p>The invention belongs to the technical field of accessories for doors and, in particular, relates to a device for blocking doors, particularly armour plated doors, in a partly open position with the certainty of any possibility being prevented of the blocking of the door being overcome through action taken on the outside thereof. The solution to the problem is obtained with a device 1 having an arm able to be oscillated and comprising at least one pin 4 that fits rotatably in a housing 1a placed in the floor; a thin part that extends perpendicularly to the said pin and is integral therewith; and a projecting stop 6 integral with the said thin part 5 and jutting out there from, the said projecting stop being connected to the said thin part through means able to fix, along the said thin part, the said projecting stop in a plurality of positions.</p> |
