Definitions

  • the present invention relates to lock mechanisms.
  • One mechanism for achieving this effect includes securely attaching a first end of a short safety chain to a doorframe and providing a receiving slot on the door in to which a second end of the chain is detachably connected.
  • the length of the chain may be altered to vary the distance to which the door may be opened and may be completely disconnected from the slot in order to open the door fully.
  • An alternative mechanism for preventing a door or window from opening fully comprises the use of a safety lever instead of a chain for connecting the door to the doorframe.
  • a first end of the lever is pivotally secured to the doorframe often located close to the central latch, and a second end, which has a slot therethrough is engaged by a moveable member which is located inside the door.
  • the catch lever hangs vertically and when the door is opened, the lever pivots upwards until at a horizontal position where the member engaging the lever prevents further movement.
  • the length of the lever determines to what extent the door can be opened and the engaging member may be disengaged from the lever allowing the door to open fully.
  • More elaborate lock mechanisms exist and comprise a moveable drive bar attached to the side of the door where vertical movement of said drive bar results in the actuation of latches, or the like, remote from the central latch. Such arrangements may also be combined with the mechanisms for preventing a door or window from opening fully as described above.
  • a problem with such arrangements using a chain or catch lever is that it can he relatively simple to break away a cover plate to enable unauthorised movement of the drive bar.
  • a lock mechanism comprising a drive bar which operates at least one latch, and a locking means operable to cooperate with said drive bar such that movement of the drive bar is prevented or suitably restricted.
  • the drive bar may be secured to a door or window by any means.
  • the drive bar may be connected along the vertical axis of the door or window by any means.
  • the locking means prevents, in use, the movement of the drive bar in any direction.
  • the locking means may cooperate with the drive bar such that vertical movement of the drive bar is prevented.
  • the drive bar may be provided with an aperture.
  • the aperture may be an elongate slot.
  • the locking means may be connected to the door or window.
  • the locking means may comprise a blocking member shaped to fill the elongate slot of the drive bar, when in a locking position.
  • the blocking member may be box shaped.
  • the lock mechanism may further comprise a safety lever.
  • the safety lever may be arranged for pivotal attachment to a door or window frame.
  • the safety lever may have an aperture therein.
  • the blocking member may have a head which is engageable within the aperture of the safety lever, when the lock mechanism is in an intermediate position, such that in use the door or window can only open to a limited extent, controlled by the length of the safety lever.
  • Means may be provided to operate the lock mechanism remotely, for example by means of a hand held unit which can be operated to send a signal to a receiver of the lock mechanism. This makes it possible for the safety lever to be engaged from outside a building as well as inside, which is not possible with prior art devices.
  • Electrical components of the remote control device may be battery operated.
  • a solar panel device may be provided, for example for incorporation in glazing of a door or window, the solar panel device being arranged to charge a battery.
  • the invention includes a locking means in combination with a drive bar as defined above.
  • the invention also includes a window or door having at least one locking means in combination with a drive bar as defined above.
  • FIG. 1 illustrates a lock mechanism generally shown as 2.
  • the lock mechanism 2 comprises a safety lever 4 which has a first end 4a and second end 4b.
  • the first end 4a is slidably connected to an elongate slot 6 of a fixing bar 8 which is secured by securing means through apertures 10 to the inside of a door frame (not shown).
  • the second end 4b has an elongate aperture 12 and is of a suitable size to accommodate a cylindrical head 14a of a body 14 which is generally box shaped and largely located within a lock housing 16.
  • Figure 2 illustrates the lock mechanism 2 in a first position and shows the body 14 connected to the cylindrical head 14a by a neck region 14b.
  • the head 14a passes through an elongate aperture 20 in a drive bar 18 which, by means of vertical movement, for example by rotation of a handle (not shown) is responsible for actuating other latch mechanisms at remote locations from the lock mechanism.
  • a handle not shown
  • the surface of the cylinder head 14a sits flush against the side of the drive bar 18
  • the drive bar is free to move in a vertical direction and, assuming that all latch mechanisms are in an unlocked configuration, the door is free to swing open.
  • Figure 3 illustrates the lock mechanism in a second position and shows the body 14 having moved to the right a distance, x 2 , in a horizontal direction.
  • the head 14a region has passed further through the aperture 20 in the drive bar 18 and now engages with the aperture 12 of the safety lever 4.
  • the drive bar In the second position the drive bar is still free to move in a vertical direction and, assuming that all latching mechanisms are in an unlocked configuration, the door is free to swing open as the safety lever 4 pivots upwardly as shown in Figure 1 until at a horizontal position when further movement is prevented.
  • the length of the safety lever 4 determines how far the door can open.
  • Figure 4 illustrates the lock mechanism in a third position and shows the cylinder body having moved even further to the right a distance, x 3 .
  • the head 14a further engages the aperture 12 of the safety lever 4, however, now the forwardly facing face of the body 14 also passes through the aperture 20 of the drive bar 18 thereby preventing movement of the drive bar 18 in a vertical direction.
  • the drive bar is unable to unlock the remote catches and it is not possible to open the door at all.
  • Movement of the body 14 may be brought about by any desired locking device, such as a cylinder lock, and because the box shaped body 14 completely blocks movement of the drive bar 18 in the Figure 4 position, the door is secure even if an attempt is made to force the lock.
  • a locking device such as a cylinder lock
  • FIG. 5 to 8 has a housing 21 in which a locking hook 22 is pivotally mounted at 23.
  • the hook 22 is pivotally connected at 24 to a plate 25 which is secured to a drive bar 26.
  • Figure 8 shows the locking hook 22 in the retract, unlocking position.
  • the hook projects through a slot in a face plate 27 which can be seen in Figures 5, 7 and 8.
  • the hook 22 has a latching effect.
  • this embodiment also has security locking means in the form of a retractable plunger 28.
  • Figure 7 shows the plunger 28 in a retracted position.
  • the plunger 28 is shown in the security position in which it has been extended to pass through a first aperture 29 in the drive bar 26. After passing through the aperture 29, the plunger then passes through an aperture 30 in the face plate 27. This effectively locks the drive bar to the face plate 27. This effectively locks the drive bar to the face plate so security is maintained even if an intruder manages to force the hook 22 into an unlatched position.
  • latches may be used instead of the hook 22.
  • the plunger 28 may be operated in any desired manner, for example using a solenoid.
  • the plunger can be operated remotely.
  • Manual means may be provided by means of which an authorised person within premises can release the plunger 28 manually.
  • the plunger 28 may be extended through a second drive bar hole 31.
  • Figure 9 illustrates an embodiment in which a locking plunger 32 can be arranged to project from a euro-groove 33 in part of the door frame 34.
  • the drive bar (not shown) is manually operated in a conventional manner using a handle 35.
  • the plunger 32 is controlled by an electrical mechanism 36 mounted on the inside of the door.
  • the mechanism 36 contains a motor 37 for driving the plunger 32 in and out, a receiver circuit 38, and a battery 39.
  • An authorised person has a remote control device which, when actuated, sends a signal to the receiver circuit 38, operating the motor 37 to retract or extend the plunger 32.
  • a solar powered device may be provided to provide backup power to the battery 39.
  • a manual device may be provided for freeing the plunger 32 from within the premises if necessary.
  • Figure 10 illustrates an embodiment similar in some respects to that shown in Figure 9, but in which a motor 40 is mounted within a housing 41.
  • the motor 41 can be operated to extend or retract a rectangular cross-section plunger 42.
  • a rotatable member 43 having a tongue 44. If the member 43 is rotated manually by a control knob (not visible in Figure 10) within the premises, the tongue 44 acts on a projection 45 of the plunger 42 and retracts the plunger. This acts as a safety override enabling the person to escape from the premises in an emergency, even if there is a power failure.
  • the various embodiments of the invention can be applied to lock mechanisms and door frames during original manufacture, or they may be retro-fitted to existing installations.
  • lock mechanisms described above has been primarily designed for use with windows or doors there may be circumstances in which the lock mechanism can be used where any opening is provided with a cover.
