(cam 25 supported in the casing, [noting that in the form shown in Fig 1 the locking Scam 25 and snib 23 are in a different location to those within the form shown in Fig 2 to 9] o and in some forms a hand operable exterior locking member 26 supported in relation to the exterior side of the wing.

In some forms, the lock is characterized by an "engaged configuration" in Swhich the engaging means 4 and engagable means 25 are connected; and while in M the engaged configuration, some locks forms may be further configured to be ci deadlocked to resist disengagement and in some locks deadlocking may correspond 00 10 to configuring the lock to a second or first locked configuration as described below.

O Characteristically, the lock can only be unlocked from the first locked configuration of Fig by the cylinder, Locks that include a Snib are characterized by what is denoted herein as a second locked configuration from which they may be unlocked by operation of the Snib or cylinder if one is included; locks that include a Snib can also be displaced into the second locked configuration by operation of the Snib.

Some locks include a Locking-Snib that is operable to displace the lock into the second locked configuration (but this is not operable to displace the lock into the first configuration and that is not operable to unlock the lock), i.e. the Locking-Snib in the exterior handle set can only be used to lock the lock.

In one form, the deadlocking slide comprises a rectilinearly displaceable member is elongated in the direction of movement and displaceable in response to cylinder and/or Snib and/or Locking-Snib operation (depending on the configuration of the lock) to displace towards and/or away from the engaging member to deadlock the latch bolt or un-deadlock the latch bolt respectively. It includes the drive recess 21 defined in part by a substantially horizontal locking drive shoulder 27 and spaced vertically from that, a substantially horizontal unlocking drive shoulder 28.

Within a second range of first cam movement, the first cam arm occupies the cam recess to operably couple the deadlocking slide and first cam together whereby translational movement of the deadlocking slide causes the first cam to angularly displace and angular displacement of the first cam causes the deadlocking slide to displace. While in this coupled mode, the deadlocking slide may be displaced to and from the second locked configuration (corresponding to a deadlock latch bolt) by actuation of the Snib (through the interspaced Snib cam described below) and by actuation of the first cam in response to key actuation of the cylinder. From this coupled configuration, the first cam may be further displaced in a locking direction, into a first range of first cam movement, (during which displacement the deadlocking 8 COMS ID No: ARCS-200986 Received by IP Australia: Time 15:37 Date 2008-08-05 FROM :PUSTRAL

The components are preferably further configured such that when the deadlocking slide is in the deadlocking position and the first cam is in 00 10 the first range of movement, the point of contact of the peripheral surface on the deadlocking slide is defined by a normal vector that passes though the pivotal axis of the first cam, In some embodiments, the Jacking shoulder is connected to an inclined surface 29 (also referred to as an exist shoulder 29) that is configured such that when the lock is in the first locked configuration the inclined surface 29 is substantially defined by a normal vector that passes substantially though the pivotal axis of the first cam so that the peripheral surface of the cam can slide over the inclined surface 29 without or without substantially, displacing the deadlocking slide that remains in cooperation with the engaging member.

When the lock is in the first locked configuration, it is desirable that it be biased against displacement from that configuration and/or require the exertion of a predetermined force or torque to do so and when the cam arm is in the cam recess it is desirable that it be biased against displacement from recess and/or require the exertion of a predetermined force or torque to do so both these objectives are achieved by the inclusion of a torsion slide spring. The slide spring is supported in a cylindrical recess in a side of the deadlocking slide below the drive recess as shown in the Figures 2 to 4 with the cylindrical coiled portion disposed about an axis that is orthogonal the sides of the casings. The spring has a spring arm that extends rearwardly to intersect the locus of movement of the peripheral end of the first cam arm and a fixed end that is restrained within a tangential slotted aperture 32. The spring arm 30 lies in plane shared by the lock body and first cam, (a plain parallel to the plane of a casing side) and between the two sides. Parts are configured such that the first cam arm cannot leave the drive recess during normal operation without displacing the slide spring arm and when the lock is in a first locked configuration, the first cam arm and slide spring arm are substantially orthogonally disposed in which configuration, the vector defining the point' on the surface of the first cam arm in contact with the spring arm, passes substantially 9 COMS IDNo: ARCS-200986 Received by IP Australia: Time 15:37 Date 2008-08-05 FROM AUSTRL LOCK Fi-inhiF hln cl~nrnr~~~~ .O o000o5oo Afu9. 05 2008 05:28PM P12 00 through the pivotal axis of the first cam. Alternatively, an angularly displaceable Srocker 30 is supported beside the deadlocking slide that amongst other functions, acts on the first cam arm to bias it against displacing from the configuration it Sassumes in the undisplaced disposition of Fig 2 and against displacing from the configuration it assumes in the locking disposition of Fig 3 by being biased towards the cylinder by a compression spring 31 held compressed between the rocker and Sa wall of the casing.

SThe Snib or other hand operable member, is supported in relation to the Cl0 interior side of the wing and in some forms, supported within the interior handle 00 10 assembly. Associated with the Snib is an angularly displaceable snib cam 32 (also referred to as the locking cam) that has a snib cam arm 34 that extends rearwardly in the casing to overlap the deadlocking slide as it does in AU16404/97 and AU77719/94; the snib cam arm having a sideways protruding shoulder preferably comprising a pinned protrusion 35 at its free end that overlaps the deadlocking slide to locate within an aperture 36 in a side of the deadlocking slide to operably couple the snib cam and deadlocking slide whereby angular displacement of the Snib cam causes rectilinear displacement of the deadlocking slide and rectilinear displacement of the deadlocking slide causes the Snib cam to rotate. The snib cam in some forms is supported by opposed cylindrical side protrusions 37 that are received one in each of a pair of opposed circular recesses 38 in the side walls of the casing all rotational parts in the lock body generally being supported in the casing in this manner. The snib cam is connected to the Snib by a snib-shaft 39 that may be integrally connected to the Snib and that extends into a mating snib cam recess 40 of the snib cam.

In some embodiment where the latch bolt is held partly extended prior to latching the lock includes an auxiliary bolt 41 displaceable between extended and retracted positions.

Some locks and in particular, particular forms of locks described above are adapted to be connected to an upper and/or a lower remote lock; these locks characterized by: a second locked configuration characterized by a fully extended latch bolt deadlocked by the deadlocking slide and fully extended remote bolts and a displaced cylinder cam arm still within the drive recess 24; where the lock can be displaced to this second locked configuration by operation of any one of the Locking-Snib, the Snib or the cylinder depending which of these elements is included, COMS ID No: ARCS-200986 Received by IP Australia: Time 15:37 Date 2008-08-05 FROM AUSIRAL LOCK PHONE NO. :61396665755 Pugj. 05 2008 05:29P1 P13 00 a first locked configuration characterized by a fully extended latch bolt ;Z deadlocked by the deadlocking slide, fully extended remote bolts and a displaced cylinder cam arm that abuts the exit shoulder 27; where the lock can be displaced to o and from this first locked configuration only by operation of the cylinder, in some forms, the fully extended remote bolts are characterized by being deadlocked by means within the remote lock that may comprise an operating rockers.

The lock outlined above, may be configured to operate remote bolts in an upper remote lock 75 and/or a lower remote lock 75 by including a rearward 00 10 extension to the deadlocking slide comprising a substantially laminar drive plate 46 o that extends through a vertically elongated rectangular slotted aperture 47 of the casing to comprise a protruding drive shoulder 48 that includes multiple circular apertures.

In one type of lock, the drive shoulder 48 includes an upper aperture So and a lower aperture 61 having a diameter substantially the same as the diameter of an upper inner Bowden cable 52 and a similar lower inner Bowden cable respectively, comprising a moveable elongated member that may be configured as a hardened steel wire. The end of the inner cable 52 (for the upper remote lock adjacent to the lock body, includes a right angle return portion 54 that passes through the- aperture 50 while the other end includes a similar return portion 55 that extends into an aperture 56 in the free end 57 of a first arm 58 of an operating rocker 69 having a substantially cylindrical portion 60 having an axial aperture 61 that is supported about a shaft 62 that defines its pivotal axis and that comprises an orthogonal extension to the wall of the remote casing 63 of the upper remote lock 75. The cylindrical portion is connected to a second arm 65 having a free end 66 configured to act on a profiled trailing shoulder 67 (on which it acts in a cam follower relationship to cause the bolt to displace towards extended position) and to act on the rear shoulder 68 of the remote bolt (on which it acts in a cam follower relationship to cause the bolt to displace towards retracted position) that is supported within a remote casing and having passage through an aperture 69 in the front wall 70 of the remote lock.

Where the elongated drive members comprise inner Bowden cables as described above, there is a corresponding outer sheath that supports the cable to restrain it against buckling and that also acts to control the effective distance between the casing and remote lock casing to ensure that the length of the displacement imparted to the cable by the lock body results in the same length 11 COMSID Na: ARCS-200986 Received by IP3 Australia: Time 15:37 Date 2008-08-05 FROM USIRPL LOCK PHONE NO. :61396865753 Aug. 05 2008 05: 29PN P14 00 12 displacement at the remote lock.
