Abstract
The present invention is directed to a new and improved design associated with the fabrication and construction of a portable self-contained intrusion device that utilizes in conjunction therewith prior art technology of expandable air bags wherein there is provided a hollow static bar member having rotatably affixed thereto a threaded collar member which is capable of receiving a threaded pressure bar member such that upon rotational movement of the threaded collar member, the pressure bar member is either extended from or retracted into the hollow static bar member thereby causing the selective positioning of the portable self-contained intrusion device across any inwardly opening door. By having wedge members affixed to to exposed ends of the static bar member and the pressure bar member respectively, there is achieved a stable method to quickly and silently place across an inwardly opening door the portable self-contained intrusion device. By having a pressure plate that is capable of being selectively aligned between the hollow static bar member and the door to be forceably opened and which is capable of having positioned between itself and the door in question an expandable air bag, a method is achieved for gaining quick forceable access to an entryway as is required in many situations associated with police activity.
