A door security device comprising an elongated body member which has a head section at one end adapted for employment in proximity to a door, a reduced intermediate section, and a gripping section at the other end, adapted to engage the floor of the room into which the door opens. The gripping section is provided with a bottom facing having a downwardly depending stop adapted to engage the horizontal floor surface of the room in a gripping action and limit movement of the elongated body member upon the application of a horizontal force component through the head section. The head section comprises a generally vertical bumper face adapted to contact the door near the floor to provide a relatively shallow acute angle between the bumper face and the stop of the gripping section. The head section has a rearwardly projecting ledge portion terminating in a vertical bumper face adapted to engage the door in an abutting relationship near the bottom of the door and a pedestal portion which is displaced inwardly from the bumper face. The pedestal portion extends downwardly from the ledge portion, which is thus spaced above the floor, to a pedestal face adapted to engage the floor. The intermediate section is of a generally arched-shaped configuration to facilitate handling of the elongated body member. An alarm is incorporated into the door security device along with a switch for the alarm and a contact means in the bumper face for activating the switch.
