Definitions

  • This invention relates to locks of the kind including a bolt which is movable between lock and unlock conditions. Such locks are commonly used to secure doors and the like in a closed position. It will be convenient to hereinafter describe the invention with particular reference to door locks, but it is to be understood that the invention has other uses.
  • the invention provides a lock assembly that includes an arrangement for adjusting the hand of the assembly, a lock assembly that is electrically operable and includes an arrangement for minimising power consumption, a solenoid operated lock assembly that is readily convertible to provide either a fail-safe or fail-secure mode of operation, and a key override monitoring facility for a lock assembly.
  • the "handing" of a lock assembly refers to the side or sides of a locked door from which a user will be unable to open the door. Such handing is usually defined relative to a direction across a door from the hinge side.
  • the handle or knob hereinafter the term handle is to be understood as including a knob
  • the handle on the right side of the said direction will not operate the assembly when it is locked whereas the left side handle will.
  • the inoperable handle is on the "outside" of the door such that persons on the other side, for example persons inside a room, will be able to open the door.
  • a lock assembly may be "interconnected", which means that when the lock assembly is locked, both the left and right side handles are inoperative to move the bolt.
  • a known lock assembly that includes an arrangement for adjusting the hand of the assembly is described in Australian Patent application No. 6/01355 PC ⁇ 7AU95/00376
  • the particular arrangement which is described includes a pivoted lever which carries two catches. Each catch is settable by a screw, against the bias of a spring, into a position where, on pivoting of the lever it will interact with the lock's actuator mechanism to prevent operation of the lock by one of the handles.
  • the setting of one or other of the catches to move with the lever determines the hand of the lock, and if both are so set, the lock will be arranged for interconnected operation.
  • the screw for a catch is removed, the spring urges the catch away from the actuator mechanism and presses it against a wall of the lock's casing.
  • 10589/92 is relatively complex and would be unsuitable for use in locks where space is very limited, for example in short backset locks.
  • the invention also relates to a solenoid controlled lock of either the fail ⁇ safe or fail-secure kind.
  • a solenoid driven component of the lock is arranged to adopt a lock release condition in the event of a power failure whereas in the fail-secure kind of lock, a solenoid driven component is arranged to adopt a lock secure condition in the event of a power failure.
  • the solenoid driven component may be directly or indirectly connected with a detent so as to move the detent between active and inactive positions; that is the locking mechanism may include electrically operated drive means as exemplified by a solenoid.
  • a problem with electrically operated drive means in a lock assembly is that the power needed to overcome the inertial mass of the mechanism to move it from an unlocked to a locked condition (for example in a fail-safe lock) or from a locked to an unlocked condition (for example in a fail-secure lock) may be excessive.
  • a manifestation of this problem, where the electrically operated drive means is a solenoid is that the size of the solenoid needed to move the locking mechanism may be too large relative to the available space in the lock. Thus space constraints may dictate the maximum size and hence the power of a solenoid that may be used. In any event, an arrangement for an electrically operated drive means that minimises power consumption is clearly desirable.
  • the present invention offers an alternative arrangement to that disclosed in AU 10589/92 for adjusting the hand of a lock mechanism which may be of simpler construction and suitable for use in short backset locks.

That is, there is a single carrier or detent which responds to the locking mechanism and which carries one or two locking heads which is /are fixedly held thereon in a predetermined position, being one or the other of two adjustment positions.
  • the mounting of the catches is such that either one or both may be rendered independent of movement of the pivoted lever.

  • the actuator means may comprise a split hub assembly such that the lock bolt is independently operable by a handle receivable in the actuator means on either side of the lock assembly and the sliding locking head may be arranged to render the handle on either side operative or inoperative.
  • the detent includes two locking heads for interacting with a split actuator means, wherein each locking head is slidingly adjustable independently of the other locking head to selectively render a handle on one side of the lock assembly operative or inoperative.
  • a lock assembly including a split hub actuator means and a detent having two locking heads according to the invention allows the lock assembly to be set such that for either hand of operation, a handle on one side of the lock assembly, or a handle on the other side, or both may be rendered inoperable for the active (that is locked) position of the detent.
  • the locking head or heads on the detent may be mounted for sliding movement thereon by any suitable means, provided such means is able to hold the head in its adjusted set position.
  • One such means may comprise a set screw passing through a slot in the detent and engaging a threaded hole in the head such that, on loosening the screw, the head is slidably adjustable along the length of the slot and, on tightening the screw, the head is fixable in a set position at either end of the slot.
  • the position of the or each locking head on the detent may be altered between either of two positions by a cam or eccentric arrangement.

Il comprend un pêne (1, 3) qui est mobile entre une position verrouillée et une position déverrouillée, grâce à un moyen d'actionnement rotatif à moyeux détachables (5a, 5b), chaque moyeu comprenant un trou traversant carré (6) pour recevoir la tige d'une poignée correspondante. Un mécanisme de verrouillage du système comprend un ergot (7) qui peut être déplacé entre une position inactive et une position active, par l'action d'un solénoïde (9). L'ergot comporte deux têtes de verrouillage (10, 11) qui sont montées d'une manière ajustable sur l'ergot (7) pour que l'une des têtes ou les deux puissent empêcher la rotation d'un ou des deux moyeux (5a, 5b), lorsque l'ergot est dans sa position active, en venant en contact avec une surface de butée (21a, 21b) sur les moyeux. Le système de serrure comporte également un levier pivotant (53) pour faciliter le passage entre un mode de fonctionnement où le verrou reste fermé en cas d'une défaillance du courant et un mode de fonctionnement où il reste ouvert en cas d'une défaillance du courant et des ressorts (59 ou 61) pour diminuer le poids (force) de l'ergot (7) s'exerçant sur le solénoïde (9), afin de minimiser la consommation de puissance. On décrit également un dispositif associé à une serrure à barillet (8) qui est prioritaire par rapport à la clé. Ce dispositif comporte un microcommutateur (201) et un moyen (207) pour l'actionner à l'aide d'une serrure à barillet (8) soit 'main gauche', soit 'main droite'.
