Definitions

  • the present invention relates to locks.
  • the invention seeks to provide a lock which, while normally operable only by authorised key-­holders also has a provision for release electrically in response to a signal from a remote control station.
  • a need for locks having this facility arises, for example, in corrective institutions or other secure buildings where passage through specified doors is usually to be restricted to authorised personnel but where, in the event of fire or some other emergency, it is necessary to unlock the doors quickly under central control to permit the egress of all persons in the locality.
  • the invention accordingly provides a lock comprising: a bolt movable between locking and unlocking positions and means for blocking movement of the bolt from its locking to its unlocking position; a key-recognition mechanism with means whereby said blocking means can be released and the bolt moved between its locking and unlocking positions by turning a correct key; an emergency release member separate from the bolt and spring means permanently biasing that member to move in a sense in which it can release said blocking means and move the bolt from its locking to its unlocking position, independently of the key-recognition mechanism; a detent member normally holding said emergency release member in an inoperative position; an electromagnetic actuator adapted, when energised, to release the detent member to permit the emergency release member to move in the aforesaid sense under the force of said spring means; and means whereby subsequent turning of the correct key in the sense to move the bolt to its locking position is effective to reset the emergency release member to its said inoperative position.
  • the lock illustrated in Figure 1 is a mortice lock having a forend 1 and a case 2 closed by a cap 3. It includes a reciprocable latch bolt 4 which can be withdrawn against its spring bias 5 by handles (not shown) on both sides of the door linked to a follower 6 by the usual square-sectioned spindle. A return spring 7 acts on the follower 6 via a tie 8.
  • the lock also includes a reciprocable dead bolt 9 the movement of which is normally under the control of a locking cylinder (not shown) mounted through the aperture 10 in the case and cap. More particularly the cylinder acts through a runner 11 (see also Figures 2 and 3) which is borne by a pair of pegs 12 to move along an arcuate tract 13 in the case 2.
  • Figure 1 shows the bolt 9 in its extended position in which it is deadlocked by a pin 14 upstanding from the runner 11 lying behind a surface 15 of the plate-like tail of the bolt (see also Figure 4).
  • the correct key is turned in the locking cylinder through 360° in the clockwise sense (as viewed in Figure 1) so that a thrower (not shown) on the cylinder engages the drive face 16 of the runner 11 and moves the runner clockwise to the opposite end of its track 13, in so doing the runner pin 14 engaging the drive face 17 of the bolt 9 and drawing the bolt back into the case.
  • the mechanism finishes with the pin 14 lying in front of the face 18 of the bolt tail to block extension of the bolt.
  • the lock While withdrawal of the dead bolt 9, and hence unlocking of the door to which the lock is fitted, is normally available only to authorised keyholders, the lock also includes provision whereby, in a emergency, the bolt can be withdrawn under remote control from a central station, so that the door can then be opened by any person withdrawing the latch bolt 4 with the associated handle.
  • the mechanism includes an emergency release lever 22 (see also Figure 5) pivoted at 23 in the case and acted upon by a relatively strong spring 24 urging the lever to turn in the anticlockwise sense (as viewed in Figure 1).
  • this lever is held in its inoperative position shown in Figure 1, by means of a second, detent lever 25 (see also Figures 6 and 7).
  • the lever 25 is generally L-shaped and is pivoted on a pin 26 in the case.
  • the shorter arm 27 of the lever 25 has a slot in its end by which it is linked to the armature 28 of a solenoid 29.
  • the longer arm 30 of the lever 25 also has a slot 31 within which is received the head 32 of the lever 22.
  • This part of the lever 22 has a notch 33 which interlocks with the lever 25, so as to hold both the lever 22 against the anticlockwise bias of its spring 24 and the lever 25 against an anticlockwise bias applied to it by a spring 34 on the solenoid 29.
  • an additional reset member 38 is provided (see also Figure 8).
  • This member comprises an arm pivoted on a pin 39 in the case and articulated to the lever 22 through a pin and slot coupling 40/41, so as to pivot clockwise about its pin 39 as the lever 22 pivots anticlockwise about its pin 23, and vice versa .
  • the cylinder thrower engages the belly 42 of the member 38 to pivot the latter anticlockwise through a few more degrees and so take the lever 22 back to its interlocked position with the lever 25.
  • An advantage of the mechanism described above is that only a short pulse of electrical energy to the solenoid 29 is required in order to trigger release of the lever 22, and the force for emergency withdrawal of the bolt 9 comes from a spring 24 rather than from the solenoid itself, so power-­consumption is very low.
  • the geometry of the lever 25 means that the armature 28 need move through only a small distance, corresponding to the position of maximum attraction within the operational characteristics of a conventional solenoid, so that reliability in triggering the lever 22 is ensured.
  • the free distance through which the lever 22 is permitted to move before its foot 35 encounters the runner pin 14 means that there is no danger of the lever 25 relocking the lever 22 if the solenoid is de-energised before the lever 22 has had a chance to move the runner 11.
  • Such circumstances could arise if, for example, a person is pushing upon the door at the moment when the lever 22 is triggered. The lateral force on the bolt 9 could then cause sufficient friction to prevent the spring force on the lever 22 from withdrawing the bolt - until, that is, the force on the door is relieved at which point the lever will automatically move to withdraw the bolt.
  • Reference numeral 43 in the drawing denotes a microswitch for giving a remote indication of the withdrawn condition of the bolt 9.
