Definitions

  • the present invention relates to safes, vaults, strongrooms and the like security enclosures, and more particularly to locking mechanisms for the doors of such enclosures.
  • the door of a safe or the like prefferably be locked by means of bolts thrown from one or more edges of the door into engagement with the surrounding frame, for which purpose there is provided an externally-accessible handle, wheel or the like operating member which drives the boltwork through a mechanical transmission mounted within the door, the same mechanism, of course, being used to withdraw the bolts when the door is to be opened.
  • This boltwork is in turn locked in its thrown condition by the operation of one or more locks which throw their own bolts or other abutments into blocking positions in relation to the main boltwork or its transmission to resist subsequent retraction of the main bolts under forcing loads.
  • the present invention relates to various aspects of a mechanism of this kind which are particularly exemplified below.
  • One such aspect is the provision of one or more pivotal blocking member(s) which are turned to position(s) in which they block forced retraction of the main bolt(s) thrown from a respective edge of the door, by means of a pin-and-slot (or equivalent) coupling with a reciprocable operating member driven by operation of a said lock.
  • FIG. 1-3 there are shown the principal components of the door locking mechanism for a safe, which are assumed to be mounted in the door behind a layer of security barrier material formulated to resist breaching of the door while it remains closed and locked.
  • the illustrated assembly can in particular be produced as a module for installation in an existing or separately-manufactured safe door equipped with its own main bolts.
  • the mechanism will include sets of main bolts (not shown) which can be thrown into detentions in the associated door frame through all four edges of the door, each such set being carried by a respective bolt strap attached to a respective drive bar 1,2,3 or 4.
  • the bar 1 transmits movement to bolts at the upper edge of the door, bar 2 to bolts at the leading side edge of the door, bar 3 to bolts at the lower edge of the door and bar 4 to bolts at the hinge side edge of the door. All of these bars can be extended and retracted in unison by a central thrower which comprises a slotted disc 5 engaging a respective drive pin 6 on each bar.
  • the disc 5 is connected to a spindle 7 which passes through the thickness of the door to an external handle or wheel by which it can be turned to throw out or withdraw the main bolts in accordance with its sense of rotation.
  • the above-described boltwork can be locked when thrown by a pair of locks which in the illustrated embodiment comprise a keylock 8 and a separate keyless combination lock 9.
  • the latter is of the offset type in which the shaft 10 from the external dial is coupled to the driver through a gear train 11.
  • the bolt 12 of the keylock 8 is connected to a bar 13 which carries an abutment 14 which engages in a peripheral notch 15 in the thrower disc 5 when the boltwork is thrown and the keylock 8 is operated to extend its own bolt (i.e. downwards).
  • the disc 5 is blocked from withdrawing the main bolts if force is applied to the external handle or wheel and if end pressure is applied to any of the main bolts themselves in an attempt to drive them in it will be resisted through the connection of the respective drive bar 1-4 to the blocked disc 5. It is recognised, however, that some additional means is desirable for resisting forced retraction of the main bolts during an attack upon the safe, independently of the abutment 14, at least for those bolts which are thrown through the top, leading side edge and bottom of the door, and for this purpose three additional blocking members 16,17 and 18 are provided, for cooperation with respective bars 19,20 and 21 which are rigidly attached to the respective bolt straps at those three edges so as to move in unison with the respective main bolts.
  • the blocking member 16 is mounted on a fixed pivot 22 and is turned anticlockwise to place an abutment face 23 behind the bar 19 when the main bolts are thrown, by operation of the combination lock 9. That is to say the bolt 24 of the lock 9 carries a bar 25 which is connected by a pin and slot 26 to a crank 27 on a fixed pivot 28. The latter is connected by a pin and slot 29 to a bar 30 which is borne to reciprocate horizontally and is in turn connected by a pin and slot 31 to the blocking member 16. Accordingly, when the lock bolt 24 is extended (i.e. moved downwards) the bar 30 is shifted to the right to pivot the member 16 to its illustrated blocking position.
  • the blocking members 17 and 18 are mounted on fixed pivots 33 and 34 and are turned respectively anticlockwise and clockwise to place abutment faces 35 and 36 behind the bars 20 and 21 when the main bolts are thrown, by operation of the key lock 8. That is to say the bar 13 carried by the key lock bolt 12 is connected by a respective pin and slot 37,38 to the two blocking members 17 and 18 to pivot them to their illustrated blocking positions when the bolt 12 is extended. On the other hand, when the lock bolt is retracted to raise the bar 13, the members 17 and 18 are pivoted in the opposite respective senses to positions in which their central slots 39 and 40 are aligned with the bars 20 and 21 and accordingly permit withdrawal of the respective bolt straps by which those bars are carried.
  • the three blocking members 16, 17 and 18 are in fact of identical form, with member 18 being mounted in a reverse disposition to members 16 and 17. They each have an additional abutment face 23A, 35A and 36A respectively which is not employed in the illustrated embodiment but by which the same components may be used in a similar mechanism for a door of opposite hand to that illustrated.
  • a reciprocable shutter plate 41 having a contoured aperture 42.
  • This plate is linked to the combination lock 9 so that when the latter is unlocked the plate 41 is shifted to the right and the key for the lock 8 can be inserted and withdrawn, but when the combination lock is locked the plate 41 is shifted to the left and can trap within the key lock an inserted bitted filler piece, or blank key, and therefore blocks access through the key entrance to any picking tool.
  • the bolt 24 of the combination lock carries a plate 43 which is connected by a pin and slot 44 to a lever 45 on a fixed pivot 46.
  • the lever 45 carries a pin 47 which works in a slot 48 in the plate 41 to shift the latter in accordance with the sense in which the lever is pivoted by the plate 43.
  • the pin 47 lies in an overcentre position relative to pivot 46 in the sense of any external load applied to the plate 41 in the rightwards direction.
  • a glass-triggered relocker This comprises a sheet 49 of glass or similar frangible material (Figs 1, 2 and 4) extending behind the security barrier layer so as to be located between the front face of the door and all of the vital locking and blocking components of the mechanism.
  • the sheet 49 is connected by a cord 50 to a bolt 51 (see also Figure 5) biased by a spring 52 to extend from a housing 53.
  • the bolt 51 is normally held against the action of the spring 52 by the cord 50 in its unblocking position of Figure 5.
  • the tension in the cord 50 will be relieved and the bolt 51 allowed to extend from the housing 53 under the action of the spring 52, to the extent permitted by a stop pin 54 running in a slot 55 in the housing.
  • the bolt 51 is held in its extended position by a spring-loaded plunger 56 seen in Figures 1 and 4. In this condition the bolt 51 will act as a further blocking member resisting the forced retraction of the leading edge bolt strap through a bar 20A carried by that strap in parallel with the bar 20.
  • a second relocker is shown in Figures 1 and 4 for applying a further blocking action upon the horizontal bar 30 (and hence the blocking member 16 and combination lock bolt 24 linked to it) in the event that the cover plate 57 of the mechanism should become dislodged during an attack upon the safe.
  • This comprises another spring-loaded bolt 58 in a housing 59 which is normally held in its unblocking position by a boss 60 (Fig 3) on the cover plate 57. Should the latter be dislodged, however, the bolt 58 will be freed to move through the housing 59 to the extent permitted by a stop pin 61 and thus block retraction of a pin 62 carried by the bar 30.
  • a spring-loaded plunger is shown at 63 for holding the bolt 58 in its extended position when triggered in this way. While the bolt 58 remains in its unblocking position, however, normal retraction of the pin 62 and bar 30 under the control of the combination lock 9 is permitted by the reception of the pin 62 in a bore 64 in the side of the bolt. The reception of the pin 62 in the bolt 58 also provides a means for preventing release of the latter when the cover plate 57 is removed by authorised personnel e.g. for servicing of the lock mechanism, since in those conditions the lock bolt 24 and bar 30 will have previously been retracted by authorised operation of the lock 9.
