Description

1 IMPROVEMENTS IN LOCKS BACKGROUND Many-types of conventional multipoint locks have a central controlling lock connected to slave remote locks by connecting members. A small number of different length connecting members have been developed to suit the range of common sized doors but sometimes, these are unsuitable and door manufacturers have resorted to cutting and bending standard length connecting members - a time consuming and often unsuccessful endeavor. OBJECT It is the object of the present invention to substantially overcome or at least ameliorate one or more of the above disadvantages or to provide a useful alternative. SUMMARY According to a first aspect there is disclosed herein a lock assembly including: a centre lock including actuating means, the actuating means being operatively associated with a lock casing of the centre lock, one or more remote lock(s) spaced from the lock casing; one or more adjustable connecting member(s) operably adapted to connect the one or more remote lock(s) to the actuating means, the one or more adjustable connecting member(s) including overlapping longitudinal first and second portions wherein the effective length of the one or more adjustable connecting member(s) is adjusted by relative displacement of the overlapping first and second portions; and one or more fastener(s) adapted for operative insertion between the overlapping first and second portions so as to restrain relative displacement of the overlapping first and second portions, thereby restraining adjustment of the effective length of the one or more adjustable connecting member(s). According to another aspect of the invention, there is disclosed a lock for a displaceable wing including an adjustable connecting member operably interconnecting a remote lock to an actuating means spaced from the remote lock, 2 said adjustable connecting member including overlapping longitudinally elongated first and second portions and means to restrain relative displacement therebetween, wherein the effective length of the adjustable connecting member is dependent on the lengths of the overlapping portions that may be electively set. Preferably, the first portion is configured as a driven portion operably connected to the actuating means and the second portion is configured as a remote portion where each said portion is straddled by means cooperable with the first and second portions to restrain relative displacement therebetween. Having regard to the distance between the remote lock and the actuating means; the normal operating forces; the need to fit within a limited space, the adjustable connecting member is preferably configured to be resistant to buckling.

Preferably, the fastener comprises a rivet or pin. Preferably, the fastener comprises a broaching-pin that during application cuts a side channel in each of the driven and remote portions. Preferably, the adjustable connecting member operably interconnects a remote engaging member within the remote lock to a slide within the actuating means, said remote engaging member displaceable to and from an operative configuration by displacement of the slide. Preferably, the lock includes an upper adjustable connecting member operably interconnecting an upper remote engaging member within an upper remote lock to the slide and a lower adjustable connecting member operably interconnecting a lower remote engaging member within a lower remote lock to the slide, said remote engaging members displaceable together to and from their respective operative configurations by displacement of the slide. Preferably, the axis of the remote portion is offset from that of the driven portion. According to another aspect of the invention, there is provided a method of setting the length of 4 an adjustable connecting member to render it suitable for a remote lock spaced a known distance from an actuating means, the actuating means being operably associated with a lock casing spaced from the remote lock, the method including: aligning one end of the assembled adjustable connecting member relative to a first mark, aligning the other end of the assembled adjustable connecting member relative to another mark spaced from the first mark a distance compatible with a connecting member suitable for the remote lock spaced a known first distance from the actuating means, and applying fastening means to relatively restrain the driven and remote portions.

In particular forms of such locks, the slide takes the form of a deadlocking slide that also acts to deadlock a bolt in the central lock. A more particular form of such a central locks is described in 77719/94 and its divisional applications, in 49195/93 and its divisional applications, in 40311195 and its divisional applications, 35 2004 250982 and 2005 250050 all of which are hereby included by reference. It - Jun. U'-! UUb2L*-M P12 9 should be noted that some of the central locks described in these patent specifications may requiring minor adaptation to become compatible with inventions described within. The inventions within will be described by way of example only with 5 reference to and in the context of a central lock having the deadlocking slide referred to above, however the inventions subject of this application are not limited to these particular applications. The inventions relate to a lock 6 including an actuating means I connected to an upper remote lock 2 and/or a lower remote lock 3 by an upper connecting 10 members 4 and a lower connecting members 5 respectively where at least one of the connecting or drive members is adjustable in length, as shown in Fig I to 3. In some forms the actuating means 1 comprises a central lock 25 that includes an engaging member configured as a latch bolt 26 and a cylinder 27 that is operable to actuate the connecting members to operate the remote locks. 15 In some forms, the remote end of the connecting member is configured to connect to the associated remote lock having a remote engaging member and in one form, the connecting member includes a return portion 12 that is received in an aperture 13 in the remote lock that in some forms is within a moveable member 79 operably associated with the remote engaging member; in some forms, the 20 moveable member comprises an arm of a pivotal rocker. In some forms, the driven end (meaning the end nearest the central lock end) of the connecting member is configured to connect to the actuating means and in one form it includes a return portion 15 that is received in an aperture 16 in a moveable member 18 of the actuating means, that in some forms comprises a 25 deadlocking slide of a central lock and in some forms the deadlocking slide extends rearwardly to protrude from rear wall of the lock casing - the aperture/s 16 being in that protruding portion. In one form, as shown in Fig 4, the adjustable connecting member includes a remote portion 19 that will be connected to the remote lock and a driven portion 30 20 that will be connected to the central lock, these portions connected by a clamp 21, as shown in Fig 5, to in effect provide a telescopic joint wherein the overall length of the adjustable connecting member can be adjusted by varying the distance the portions extend from the clamp; in these forms, the outer ends of the adjustable connecting member are adapted to be connected to the remote lock and actuating 35 means.
10 The inventions within include a method of adjusting the connecting member as shown in Fig 6, where a special ruler shows adapted lengths of connecting members corresponding to the actual measurable lengths of the distances between the centre of the central lock and an edge of the associated remote lock, ie the 5 lengths of connecting members are not actual but as required to result in remote locks separated by a desired distance form a central lock. Where the connecting members include parallel returns, as shown in Fig 6, the ruler is on a planar board 41 that has a recess 42 at one end (orthogonal to its plane) to receive one return and multiple recesses 43 spaced from this at pre-determined distances likely to be 10 encountered in configuring connecting member lengths. In usage, one return is inserted in recess 42 and the other return is placed in an appropriate recess 43 the clamp is aligned so that the fastener recess is orthogonal to the plane of the board at which point the fastener is applied. One of the advantages of this method, is that the return portions can be correctly relatively 15 orientated with certainty because the portions 19,20 cannot be rotated relative to the tubular portion as the fastener is applied. Before describing multiple forms of connecting members and clamps, we will describe a particularly limiting environment for which an adjustable connecting member was sought; that of a substantially conventional Australian security door 20 framed by members characterized by an elongated hollow substantially 16 MM wide and 40 MM deep into which the central and remote locks is fitted. Given the sizes of common security door locks in Australia where the central lock body extended into the hollow to within a small distance of the rear wall of the hollow (and not greatly exceeding the diameter of a cylindrical wire rod having a 25 diameter of about 4.5 MM from which commonly employed connecting members are constructed) and where the remote locks extended into the hollow to a greater but still small distance of the rear wall of the hollow and having as one of the objectives of the inventions within to provide an adjustable connecting member for existing common central locks, solutions were sought where 1) the adjustable connecting 30 member did not protrude more that a small distance from the rear of the central lock body and 2) not more that a greater but still small distance from the rear of the remote lock bodies and 3) could fit within the width of 16 MM of the hollow. Having regard to the above constraints and to the facts that 1) the construction of the central and remote looks requires connecting members to be disposed sideways 35 relative to the 16 MM wide hollow, 2) remote locks are disposed up to about 1 meter 11 from the central lock and 3) the connecting members need to be resistant to buckling when subjected to the force corresponding to the point where further turning of the key shears the head off points us towards a solution comprising commonly employed cylindrical wire rods having a diameter of about 4.5 MM and 5 where the remote portion 19 and driven portion 20 lie in a plane parallel the face of the door so as to occupy minimum width within the channel. Of the various connecting members conceived and described within, that described immediately below is best suited to Australian security doors. Some forms of connecting member, as shown in Fig 7 and 8, include the 10 remote portion 19 and driven portion 20 described above and a clamp 21 that includes adjacent longitudinally elongated apertures 23 defined by substantially parallel longitudinal axii and between them is a lateral aperture 22 that in one form is defined by an axis that passes between the portions in a direction substantially orthogonal to the plane defined by the substantially parallel longitudinal axii, this 15 lateral aperture 22 intersecting each of the elongated apertures 23 to form openings to the elongated apertures 23 or to form thin deformable walls between the lateral aperture 22 and the elongated apertures 23. The lateral aperture 22 is configured to receive a fastener 24 such that when the fastener is inserted, it extends into the apertures 23A and 23B to engage the remote portion 19 and a driven portion 20 20 that in some forms are identical. Trials have shown that in some cases, using some adjusting methods, the act of inserting the fastener 24 causes the portions to rotate relative to the clamp so in some forms, an expandable hollow cylindrical tube 25 that may comprise a substantially conventional roll-pin 32 is driven into the lateral aperture 22 to be 25 deformed by being pressed sideways by the portions and to give rise to reactionary force/s that act on the sides of the portions to urge them apart and against the walls of the apertures 23A, B and give rise to frictional forces that act to restrain relative displacement between the portions and the clamp and in a particular form the diven and remote portions are held slightly pressed on by the tube 25 but such that they 30 can be displaced but with minimal force to facilitate adjustment. Subsequently, a fastener 24 is inserted by force into the axial aperture 26, in the roll pin to force it to assume a large internal and external diameter whereby to urge the portions apart and without urging the portions to rotate. In some forms, the apertures 23A is connected to an outwardly disposed 35 side opening 27A that leaves a portion of the remote portion within exposed and 12 the apertures 23B is connected to an outwardly disposed side opening 27B that leaves a portion of the driven portion within exposed 23B. The side openings 27A,B are each configured such that the sideways forces exerted on the driven and remote portions by the insertion of the fastener cause the exposed portions in-part to 5 displace sideways away from each other and into their associated side openings 27A, B: this displacement in-part being enabled by deformation of the driven and remote portions that as a consequence gives rise to reactionary force/s that act of the sides of the tube 25 and on the walls of the apertures 23A, B that cooperate to hold the remote portion 19 and driven portion 20 elastically deformed and as a 10 consequence giving rise to frictional forces that act to restrain relative displacement between the remote portion 19 and driven portion 20 and clamp under normal operating loads. Obviously, the further the driven and remote portions are displaced (in-part) into their associated side openings 27A, B the larger will be the frictional force. Trial and error has proved that the clap shown in Fig 6 is well suited to 15 security door look applications. The clamp described immediately above is also particularly well suited to driven and remote portions having a tolerance on diameter that is relatively large, the deflection into the side openings accommodating tolerance in excess of the minimum diameter. 20 In a particular form, the driven and remote portions are constructed from resilient elastically deformable material such as partly hardened steel wire or rod. In this case, the insertion of the roll-pin urges the driven and remote portions apart till they abut against the walls of the apertures 23A, B whereupon insertion of the fastener 24 urges the exposed portions of the driven and remote portions apart to 25 deform the driven and remote portions as they are displaced into side openings 27A, B and giving rise to reactionary forces that act inwardly on the opposite sides of the roll-pin and giving rise to increased frictional forces that act to restrain relative displacement between the clamp and driven and remote portions. In a particular form, the driven and remote portions comprise round bars and the apertures 23A 30 and 23B are substantially cylindrical. In a particular form of side opening 27A, BA extend inwardly to meet the apertures 23A and 23B and they have a width equal to the diameter D of the apertures 23A and 23B. In a particular form, the side opening 27B, A are substantially identical in form, opposed and extend equal distances longitudinally in 13 both directions away from the lateral aperture 22 to terminate before the respective ends of the clamp. This embodiment can be represented by the following, as shown in Fig 8: if the driven and remote portions have a diameter d1, the undeformed tube 25 (roll 5 pin) has an inner diameter d4 and an outer diameter d3 (and an effective wall thickness (d3-d4)/2 and the outer surfaces of the driven and remote portions are separated by a distance of L, then in a configuration where the tube 25 is held slightly compressed (by being compressed to an effective diameter d3o ) such that the first members can be displaced but with minimal force can be represented by: 10 dl + d3 - d3dt + dl = L assuming the driven and remote portions are not deformed by the insertion of the tube 25. When the fastener 24 having a diameter d5 has been installed, dl+ d5 +(d3-d4) +dl - L + 2 Lma where Laelt, is the distance the driven and remote portions are displaced into 15 a respective side opening 27A, B and assuming the sides of the tube 25 and sides of the driven and remote portions remain substantially undeformed and for this to occur the hardness of the tube 25 the driven and remote portions are comparable. In a preferred form, lateral aperture 22 is bounded by a tube shoulder 33 being a portion of the lateral recess of lesser diameter that prevents the tube 25 20 from being driven further into the clamp while providing passage for the fastener 24 and so when the fastener is driven in, the tube 25 expands without longitudinally displacing and without exerting a moment on the driven and remote portions urging them to rotate. In a particular form, as shown in Fig 5, that is suitable for conventional 25 Australian security door and is adaptable to suit common Australian security door locks: L= 13.50, d1=4.50, d5 +(d3d4) = 3.2, the axii of the elongated apertures 23 are separated by 6.25 requiring the driven and remote portions to be displaced into the side recesses as the fastener is inserted, the walls of the clamp surrounding the lateral aperture 22 are minimized within practical limits and the width of the clamp is 30 9 MM enabling it to fit within the 16 MM width (even when offset as required by common Australian security door locks) and to be compatible with common Australian security door locks. In some forms, the roll-pin 32 and fastener 24 described above are combined into a single pin 28 that is simply driven into the lateral aperture 22 to 35 urge the exposed portions of the driven and remote portions apart to deform the 14 driven and remote portions as they are displaced into side openings 27A, B and giving rise to reactionary forces that act inwardly on the opposite sides of the roll-pin and giving rise to increased frictional forces that act to restrain relative displacement between the clamp and driven and remote portions. In this case, the rods need to be 5 restrained against rotation as the pin is driven in. In some forms, as shown in Fig 9, the pin is configured as a broaching-pin 29 having a hardness in excess of the hardness of the driven and remote portions to facilitate cutting and it has at least one peripheral sharp cutting shoulder 30 that overlaps the apertures 23A and 23B and configured so that during insertions 10 grooves are broached in the sides of the driven and remote portions to better retain the driven and remote portions against relative displacement. In a particular form, the broaching pin 29 is substantially cylindrical having a diameter D and the cutting shoulder 30 is defined in part by this diameter D. In some forms, the broaching pin has a generally tapered leading end and multiple spaced circular cutting shoulders 15 31 having diameters that get progressively larger so insertion causes the cutting shoulders to cut orthogonal channels in a side of the driven and remote portions. The mechanism is such that the broaching-pin 29 will continueto cut/deepen the orthogonal channels till the outwardly directed component of force associated with cutting exceeds the inwardly directed forces resulting from deformation of the first 20 members at which time, the first members will deform away from the cutting-pin 29 as the exposed portions displace further into the side opening 27A, S Where the cutting-pin is configured to have multiple cutting shoulders, a tapered side of the leading end of the cutting-pin may at some time during this process act directly on the first members to urge them apart. 25 In some forms, as shown in Fig 10, the driven and remote portions comprise hollow tubes one of which extends into the other and in some forms, the internal diameter of one is substantially the same as the external diameter of the other but with working clearances and where they overlap they are straddled by a sleeve 44 that includes an orthogonal aperture 45 that extends to intersect a cylindrical 30 aperture 48 through which the driven and remote portions extend one inside the other and after the portions are adjusted to achieve the desired length, a fastener 47 is driven inwardly through the orthogonal aperture to deform or puncture the walls of both the driven and remote portions to prevent relative displacement In another similar form, as shown in Fig 11, the driven and remote portions 35 have a cross-section having an external form that is substantially semi-circular so 15 that together in the assembled form, they occupy the circular aperture 48 in a sleeve 49 and where the fixing recess extends inwardly to intersect this circular recess 48 and after the portions are adjusted to achieve the desired length, a fastener 50 Is driven inwardly through the orthogonal aperture to puncture the wails 5 of both the driven and remote portions to prevent relative displacement. In another form, as shown in Fig 12, at least one of the driven and remote portions includes a tubular portion 51 into which at least one end portion 52 extends to effect a telescopic joint; the length of the adjustable connecting member being adjusted by varying the distance the at least one end portion extends from the 10 tubular portion 51. In one form, the tubular portion 51 includes a longitudinally extended side slot 53 that connects to a longitudinally extended longitudinal bore 54 (that may be coaxial with the tubular portion) that extends longitudinally beside the side slots. In a particular form, the side slot extends for the entire length of this tubular member and the bore comprises an axially extended bore that similarly 15 extends for the entire length of this tubular member. In some forms, one end of each end portion 52 includes a through fixing aperture 55 configured to receive a fastener 56 - in some forms, the diameter of the fastener shank (which extends through the side slot) is configured to be substantially the same so that the end portion can be displaced into and from the bore while fastener slides longitudinally in 20 the slide slot to restrain the end portion from angularly displacing relative to the tubular portion. Once assembled, the members are relatively aligned and adjusted to provide the desired length and the fastener is driven inwardly to deform or puncture the opposite wall of the tubular member to prevent any relative displacement. In some forms, the opposite wall has pre-drilled apertures 57 to 25 receive the fastener. In other forms, as shown in Fig 13, each connecting member 2,3 includes a first portion 60 and a second portion 61 connected by a threaded shaft 62; the portions including an internally threaded recesses 63 and 64 respectively that are engaged (or engageable with) with the threaded shaft 62; the length of the 30 connecting rod being adjusted by rotating one or both portions relative to the threaded shaft 62. In some forms, each portion 60, 61 comprises an elongated portion attached to a nut or threaded member 65; where in a particular case the elongated portion has a diameter substantially the same as common connecting rods and the threaded member 12 comprises an elongated sleeve nut 66 that is 35 attached to the elongated portion by welding, soldering or other means. As is 16 common, each connecting rods has ends adapted to be connected to the central lock and remote lock. The inventions described herein include the locks included herein by reference adapted to include an adjustable upper and an adjustable lower 5 connecting members 4,5 having a form described herein. In one such case, the adjustable connecting member is used in conjunction with the locks described in 77719/94, 49195/93 by simply adapting the deadlocking slide to protrude through the rear of the casing so that recesses 70 in this deadlocking slide are accessible and to receive the retums15 and 12 (ie. a recess for the upper and a recess for the 10 lower connecting members). Similarly, the adjustable connecting member can be used in conjunction with the locks described in 250982 and 2005250050 by simply adapting the deadlocking slide to protrude through the rear of the casing as described above. The adjustable connecting member can also be used in conjunction with the 15 locks described in 40311/95 and the divisional applications by simply adapting the deadlocking slide to extend rearwardly from beneath the casing to protrude from the plane defining the rear of the casing so that recesses 71 in this portion on the deadlocking slide are accessible to receive the returns 5. 20
