Definitions

  • the present invention relates to the field of security devices for door locks, more particularly to a security device for dead bolt locks.
  • a drawback with the above-mentioned first type of devices known in the art is that in general, they are mainly adapted to latch bolt locks and not to dead bolt locks. If they are adapted to dead bolt locks, their mechanism is usually independent from the mechanism of the lock itself. Thus, for securely locking a door with those types of security devices, the door lock must be first engaged and then, in a second step, the security device has to be engaged. Examples of such prior art devices are described in US patent nos .
  • An object of the present invention is to propose a security device for a door lock which satisfies the above- mentioned needs. More particularly, the present invention proposes a security device for a dead bolt lock, the dead bolt lock including a dead bolt and being mounted on a door having a given outline, the door itself being mounted in a doorframe provided with a door stop on which the door abuts when it is closed, an inner surface surrounding the door when the door is closed, and an outer lateral surface disposed opposite the door stop with respect to the inner surface, the dead bolt is movable between an unlocked position where it remains inside the outline of the door thereby allowing the door to open, and a locked position where the dead bolt juts out over the outline of the door and engages a cavity provided for that purpose in the inner surface of the doorframe.
  • the security device is characterized in that it comprises: a first rigid vertical plate for attachment to said doorframe and shaped to extend flat on the outer lateral surface of the doorframe opposite the door stop just in front of the cavity in the doorframe; a security lever mounted on said first plate and pivotable about a vertical axis adjacent to the first plate the security lever including an inner arm on one side of the first plate for extending in the cavity of the doorframe for engagement with the dead bolt when the dead bolt is moved to the locked position thereby causing the lever to pivot around said vertical axis, the security lever further including an elongated outer arm integral with the inner arm and extending on another side of the first plate opposite said one side, shaped and sized for abutment on an outer surface of the door when the dead bolt has been moved to the locked position and has caused the lever to pivot around said vertical axis; and first fastening means for securing the security device via the first plate to the doorframe.
  • the security device further comprises a second rigid vertical plate integral to the first plate and shaped to extend flat on the inner surface of the doorframe, the second plate being provided with an opening set to face the cavity in the doorframe and for receiving the dead bolt; and second fastening means for securing the security device to the doorframe via the second plate.
  • the security device further comprises a rigid sleeve integral to the first and second plates, the sleeve being coaxial with the opening provided in the second plate and extending in the cavity of the doorframe for receiving the dead bolt as it is in a locked position.
  • the locking of the dead bolt lock is performed in only one step by simply engaging the door lock thereby engaging the security device simultaneously.
  • a security device greatly lowers the chances that someone knock down the door.
  • Another advantage of a security device according to the present invention is that it is of simple construction, low in cost and very easy to install on a doorframe.
