Multiple Dead Bolts Patents (Class 70/103)
  • Patent number: 11725419
    Abstract: Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform. In a particular embodiment, an embodiment of the invention may include a security system involving a plurality of door locations having a plurality of networked door blocking apparatus. Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.

  • Patent number: 9003843
    Abstract: Disclosed in one aspect is the fixed door pull handle assembly that includes an elongated door pull handle with two or more support standoffs projecting away from the elongated door pull handle and securing the elongated door pull handle to the doorframe or to the body of the door. One of the support standoffs is user rotatable, and rotatably engages a door latch assembly within the door. In another aspect, the support standoff is not user rotatable. Instead, a center-pivoting handle is mounted in-line with one of the support standoffs and rotatably engages the door latch assembly within the door. The center-pivoting handle is recessed within the elongated handle.

  • Publication number: 20080184749
    Abstract: An intuitively operable door locking arrangement and a method include, a lock-point arming input element that is connected directly to a handle-operated control element of the locking arrangement, rather than being connected directly to a lock-point of the door locking arrangement. The locking arrangement and method may be used in hinged single or multiple-panel installations, having single, and/or multiple lock-points, may allow keyless locking from outside, and may include a latching arrangement. In active door locking apparatuses, the lock-point is movable only through operation of the handle-operated control element. The lock point arming element is selectively moveable between an armed and a disarmed position thereof, and is configured and connected to the handle-operated control element in such a manner that the handle-operated control element may be used to move the lock-point to the locked position thereof only when the lock-point arming input element is in the armed position thereof.

  • Patent number: 6837082
    Abstract: A door security system for use in conjunction with a building having an existing doorway, for providing enhanced security to the occupants of the building. The door security system has a steel door hingeably attached to a steel doorframe. The steel door has a plurality of evenly spaced steel vertical rods, and a plurality of metal plates which overlay and are attached to the vertical rods, thereby conferring great strength to the door. The central plate has two deadbolt locks, and a cover plate in proximity to the deadbolt locks. The cover plate prevents an individual from inserting an object between the door and the doorframe, in an attempt to push the lock bolts from their corresponding bolt recesses within the doorframe. The door security system may be installed within any suitably sized doorway within the existing building to provide a sense of security to the occupants.

  • Patent number: 4067212
    Abstract: A two dead bolt door lock is disclosed wherein the bolts are transversely disposed and wherein the bolts are disposed one behind the other in the locked position so as to provide a secure locking mode. When door mounted, and in the locked position, a vertical bolt is disposed on the inside of the door adjacent the jamb and a horizontal bolt is mounted in the jamb. Attempts to jimmy the horizontal bolt in its line of least resistance are frustrated by the presence of the vertically locked bolt acting against the jimmying force. The locks are both operated by a single key actuated cylinder and/or hand knob through a common connection rod with coordinated cam actions. In another embodiment, keys may be employed on both the inside and the outside of the door.
