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.
  • a security device according to the first part of claim 1 is known from FR-A- 2050 713.
  • 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:
  • 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.
  • a security device As can be appreciated, with a security device according to the present invention, 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. Moreover, the outer arm of the lever, which abuts the door behind the bolt in the locked position, thus reinforcing the lock, acts as an armour. Such 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.
  • the security device (2) is used mainly for reinforcing a conventional dead bolt lock (4).
  • the lock (4) is mounted on a door (8) having a given outline (10).
  • the door (8) itself is mounted in a doorframe (12) provided with a door stop (14) on which the door (8) abuts when it is closed.
  • the doorframe (12) further comprises an inner surface (16) surrounding the door (8) when it is closed, and an outer lateral surface (18) disposed opposite the door stop (14) with respect to the inner surface (16).
  • the dead bolt (6) is movable between an unlocked position where it remains inside the outline (10) of the door (8) thereby allowing the door to open, and a locked position where the dead bolt (6) juts out over the outline (10) of the door (8) and engages a cavity (20) provided for that purpose in the inner surface (16) of the doorframe (12).
  • the security device comprises a first rigid vertical plate (22) shaped to extend flat on the outer lateral surface (18) of the doorframe opposite the door stop (14) just in front of the cavity (20) in the doorframe (12).
  • the inner arm (34) of the lever (30) is preferably sized for extending only partially within the cavity (20) of the doorframe (12) and has a shape adapted for engagement by a lateral surface (46) of the dead bolt (6) when the dead bolt (6) is in a locked position.
  • the security device (2) further comprises a second rigid vertical plate (24) integral to the first plate (22).
  • This second plate (24) is shaped to extend flat on the inner surface (16) of the doorframe (12), and is provided with an opening (26) as shown in Figure 3, set to face the cavity (20) in the doorframe (12) and for receiving the dead bolt (6). It has to be noted that another preferred embodiment of the present invention may very well comprise only the second above-mentioned plate without departing from the scope of the present invention.
  • the security device (2) further comprises a rigid sleeve (28) integral to the first and second plates (22,24).
  • This sleeve (28) is coaxial with the opening (26) provided in the second plate (24) and extends in the cavity (20) of the doorframe (12) for receiving the dead bolt (6) as it is in a locked position.
  • a security lever (30) is mounted on the first plate (22) of the security device (2) and is pivotable about a vertical axis (32) adjacent to the first plate (22).
  • the security lever (30) includes an inner arm (34) extending on one side of the first plate (22) in the cavity (20) of the doorframe (12) or in the sleeve (28) when the device (2) is provided with such a sleeve (28) as illustrated in FIG. 1.
  • the inner arm (34) extends in a position such that the dead bolt (6), in the locked position, abuts on the inner arm (34) and causes the lever (30) to pivot around its axis (32).
  • the lever (30) further includes an outer arm (36) extending on another side of the first plate opposite said one side, shaped and sized to extend on the door (8) behind the dead bolt (6), when the dead bolt has been brought to the locked position and has caused the lever (30) to pivot around its axis (32).
  • the outer arm (36) of the lever (30) is preferably flat and has an elongated shape.
  • the first plate (22) is provided with an opening (38) on the inside of the sleeve (28), the vertical axis (32) or hinge of the lever (30) extending across this opening.
  • the device (2) - further comprises first and second fastening means for securing the security device via the first and second plates (22,24).
  • Those fastening means may be screws or any other fastener known in the art such as nails, bolts, etc.
  • the outer arm (36), as it abuts on the door (8), is greatly reinforcing the door lock (4) as acting as an "armour".
  • a device according to the present invention greatly lowers the chances for anyone to knock down the door.
  • the height of the first and second plates (22,24) is greater than the height of the opening (26) in the second plate (24).
  • those plates (22,24) have a height at least three times greater than the height of the opening (26) in the second plate (24).
  • the first plate (22), the second plate (24), the sleeve (28) and the lever (30) are preferably made of metal and the sleeve (28) may be welded to the first and second plates (22,24).
  • the security device (2) preferably further comprises a tightening means disposed inside the sleeve (28) for keeping the dead bolt (6) tight as it is in a locked position in the sleeve (28).
  • the tightening means may comprise a spring-leaf (40) mounted inside the sleeve (28) and facing the opening (38) in the first plate (22) and a screw (42) mounted inside the sleeve (28) accessible from the outside for adjusting the spring-leaf (40).
  • the security device (2) may also comprise spring means for bringing back the outer arm (36) in an open position as the dead lock (6) is in an unlocked position, thereby allowing the door (8) to freely open and close without hitting the outer arm (36).
  • the spring means may comprise a spring (43) operatively mounted at one end of the hinge (32).
  • the security device may also comprise a protective covering or hood (not illustrated) mounted on the security device and adapted to receive the outer arm.
  • this protective covering is used for hiding and protecting the outer arm.
  • the inner arm (34) of the lever (30) has a rounded outline (44) on which a lateral surface (46) of the dead bolt (6) abuts when the dead bolt (6) is in a locked position.
  • the inner arm (34) of the lever (30) may have a hollow portion (48) defining a passage between the opening (38) in the first plate (22) and the screw (42) of the spring-leaf (40), thereby making the screw (42) accessible from the inside.
  • this embodiment may further comprise adjustment means for adjusting the lever to any length of dead bolt.
  • These adjustment means may comprise a spring mounted on an inner face of the inner arm.
  • the lever (30) has an L-shaped cross-section, the inner arm (34) then corresponding to the short portion of the L and the outer arm (36) corresponding to the longer portion of the L.
