  • Patent number: 6471264
    Abstract: A door security device operative to secure the door in a fully closed and partially opened state is disclosed. A vertically oriented housing mounted close to the handle side on the inside surface of the door contains a coaxial brace bar, the bottom end of which extends out of the housing, but does not reach the floor. A second vertically oriented brace bar is slideably mounted onto horizontal rods, which are affixed proximate to the bottom of the vertical brace bar. To lock the door, the bottom end of the slideable brace bar is inserted into one of two different floor plugs, the first of which is positioned adjacent to the location of the closed door (bracing the door in a fully closed position) and the second of which is positioned slightly interior to the first (bracing the door in a manner that allows it to be partially opened). If no security is desired, the entire device may be lifted in the housing, rotated into planar contact with the door, and locked in an inactive position.

  • Patent number: 5531490
    Abstract: A door security device allows partial opening of a door by coupling a door to a floor structure. The coupling is provided by a door bar including first and second length portions in spaced, parallel relation. The first and second length portions are interconnected by a coupling portion perpendicular thereto. One length portion is pivotally mounted in a floor on the inside of a doorway. The other length portion then assumes an upstanding vertical position. As the door opens, the door engages the upstanding length portion and moves towards an open position so long as the door bar permits. Eventually, the door bar blocks further opening of the door and maintains the door in a secure condition despite partial opening. In a second mode of use, the door bar is reoriented and inserted within the pivotal mounting of the floor to pin the door shut in closed condition. The door security device offers advantage in its ease of installation and use, low cost, and effective security against forced entry.

  • Patent number: 4262503
    Abstract: A security device for preventing the unauthorized opening of swinging doors. The device has two members, each of which includes two parallel tubes and a rectangular metal plate or web. Each pair of tubes is welded to the respective opposite side edges of its metal plate, and the device is adapted to slide along the floor beneath a door when the door is opened with the tubes of each pair upon opposite sides of the door. The tubes of one member are smaller than those of the other, and the pair of smaller tubes extend beyond their plate toward the other member, and are inserted into the respective larger tubes to a nested position. The overall length of the device is then such that the door can be closed. The members are then moved relative to each other from the nested position, i.e., longitudinally of the pipes so as to span the width of the door. Each pair of pipes has extensions beyond the plate which are then positioned upon opposite sides of the door frames.
