Abstract: A portable door secure system which consists of an elongate shank with a foot component coupled to a lower end of the shank for engaging a floor in front of a door and a yoke component coupled to an upper end of the shank for engaging an underside of a door knob on the door. The shank can be positioned at an angle between the door knob and the floor, to jam the door closed to prevent the door from being opened inwardly toward the side on which the device resides. The device disassembles into a very small compact light weight set of components so that it may easily be carried by a user typically a hotel or motel patron.
