<p>#CMT# #/CMT# The device has a vertical movable bar (13) placed at a door and suspended by connecting rods in front of a lock, when the bar rests on a key inserted into the lock. The bar is plugged in a latch (15) fixed at a framework of the door. The bar is raised with respect to a low initial position so as to hide the lock for infants, and is not plugged into the latch in the absence of the key in the lock. The rods are inserted into vertical slits (16), where fixation of the rods is assured by a nut (14). #CMT#USE : #/CMT# Device for blocking an opening of a door of a room in a dwelling unit. #CMT#ADVANTAGE : #/CMT# The device blocks an opening of the door such that the key is not removed from the lock, thus avoiding leaving out and forgetting to take the key from the lock. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a door opening blocking device, when a key is not in a lock. 13 : Movable bar 14 : Nut 15 : Latch 16 : Vertical slit.</p> |
