发明名称 Door security strut
摘要 A strut for holding a door in closed position, the strut comprising a tube and a rod threaded together so that the length of the strut is adjustable. The strut connects to a door bracket at two spaced locations whereby the strut is held in a fixed angular position relative to the door when in operating position. There is also a lock nut for locking the rod and tube to the adjusted length, a floor engaging pad swivelly connected to the tube, and one of the connections to the door bracket can be disengaged to permit swinging of the strut into a stored position against the door.
