579193 Patent Form No. 5 NEW ZEALAND Patents Act 1953 COMPLETE SPECIFICATION TITLE: Patch Lock Fitting We ASSA ABLOY Australia Pty Limited of 235 Huntingdaie Road, Oakleigh, Victoria, 3166, Australia, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: 579193 2 PATCH LOCK FITTING This application claims priority from Australian Application No.2008904339 filed 22 August 2008, the contents of which are to be taken as incorporated herein by this reference.

This invention relates to a patch lock assembly, and a patch lock fitting, for location adjacent a side edge of a frameless glass door panel. The fitting is 10 particularly suitable for use with a mortice lock assembly and it will be convenient to hereinafter describe the invention with respect to this application.

The term mortice lock as herein after referred in the specification is intended to include locks locatable in a mortice cavity having a movable lock bolt or a movable strike which can be moved to a release position.

Patch fittings generally include a sub-structure formed from a pair of members that clamp onto the glass door panel. A patch fitting may form part of a hinge or provide a means for attaching a lock assembly to the glass frameless door panel.

It is generally desirable for the patch fitting to securely attach to the door panel 20 so as to reduce the likelihood of unauthorised removal of the lock from the door panel.

One form of mortice lock suitable for use with a patch lock fitting includes a lock bolt that is movable out from a front face of the mortice lock housing, between a retracted and extended position by operation of a cylinder lock. The cylinder 25 lock is often attached to the mortice lock housing by way of a single pin or long thin bolt extending from a front face of the mortice lock housing. The patch lock substructure generally includes an aperture to provide access to the cylinder lock. The cylinder lock generally interacts with the substructure adjacent the aperture so as to secure the mortice lock adjacent the patch lock fitting. The 30 tolerance between the cylinder lock housing and the aperture allows for RECEIVED at IPONZ on 10 June 2010 579193 3 movement of the mortice lock assembly relative to the patch lock fitting. With repeated use of the door, the mortice lock can become loose in the patch lock fitting, and the patch lock fitting assembly including the mortice lock can become loose relative to the glass door panel. This can result in the lock becoming unserviceable to 5 the extent that the bolt may no longer locate in a strike of an adjacent jamb when the door is in a closed position. Furthermore the door furniture can also be loosened.

According to one aspect of this invention there is provided a patch lock fitting for locating a mortice lock assembly in a recess formed adjacent a side edge of a glass door panel, the fitting including; a substructure formed from a pair of plate members 10 that has a cavity for receiving the lock and at least one spacer located between the plate members and the glass door panel so as to firmly locate the fitting in the recess, the substructure also has a zone which in use is occupied by the panel, the zone being positioned relative to the cavity so as to align the mortice lock assembly substantially with the panel, the substructure being configured to facilitate connection 15 of a front portion of the mortice lock assembly to the substructure.

It is preferred that the substructure includes at least one threaded bore to receive a fastening element so as to facilitate connection of a front portion of the mortice lock assembly to the substructure.

It is further preferred that the threaded bore is configured to receive a screw that 20 extends through a face plate or mortice lock housing associated with the mortice lock assembly.

It is preferred that each plate member includes a substantially planar portion which in use extends in the general direction of the panel, at least one of the plate members includes a transverse portion that extends substantially transverse to the planar 25 portion, wherein the zone is adjacent an edge of the planar portion and further defined by the transverse portion.

It is further preferred that the transverse portion is configured to facilitate connection of a front portion of the mortice lock assembly to the substructure.

It is preferred that a retention formation in use interacts with the panel to limit 30 movement of the fitting relative to the recess.

C:\pof\temp\SPEC-NZ166S5-09.doc RECEIVED at IPONZ on 10 June 2010 579193 4 It is further preferred that the retention formation is associated with the transverse portion.

It is preferred that each plate member includes a recess to accommodate a cylindrical lock housing of the mortice lock assembly, the recess extends from a front edge of 5 the plate member so as to allow the lock housing to be located in and removed from the cavity in the substructure without detaching the cylindrical lock from the mortice lock assembly.

It is preferred that the patch lock fitting include a plurality of spacers located between the plate members, at least one spacer located between the plate members and the 10 glass door panel so as to firmly locate the fitting in the recess.

It is preferred that the patch lock fitting include at least one cover that is located over one of the plate members, the fitting including means for retaining the cover adjacent the plate.

It is further preferred that the patch lock fitting includes the means for retaining the 15 cover including at least one rotatable member that engages the cover and the plate member.

It is further preferred that the cover includes an aperture for access to the cylindrical lock housing.

It is further preferred that the pair of plate members is retained in its form of the 20 substructure by at least one fastener.

It is further preferred that the fastener is a screw or bolt.

According to another aspect of this invention there is provided a patch lock assembly for location in a recess formed adjacent a side edge of a glass door panel, the assembly including a patch lock fitting as hereinbefore defined and a mortice lock 25 having a bolt that is movable between an extended and a retracted position.

According to further still another aspect of this invention there is provided a patch lock assembly for location in a recess formed adjacent a side edge of a glass door panel, the assembly including a patch lock fitting as hereinbefore C:\pof\temp\SPEC-NZl669S-09.doc 579193 defined and an electronic mortice Sock having a strike that is movable between a locked and a release position, the strike engaging a lock bolt when the door is in a dosed position.

It will be convenient to hereinafter describe one or more embodiments of the 5 invention with reference to the attached drawings. The particularity of those drawings and the related detailed description is not to be understood as superseding the generality of the broad definition of the invention provided by the claims.

Figure 1 illustrates an isometric view of the patch lock assembly with the 10 mortice lock housing removed.

Figure 2 illustrates an exploded view of the patch lock assembly from Figure 1.

Figure 3 illustrates part of the patch lock fitting located in a recess formed adjacent a side edge of a glass door panel.

Figure 4 illustrates an assembled patch lock fitting with a mortice lock having a 15 movable swing lock bolt according to one aspect of this invention.

Figure 5 illustrates an assembled patch lock fitting with a mortice lock having a movable strike plate according to another aspect of this invention.

Referring firstly to Figure 1 which illustrates in summary a patch lock fitting 1, a glass door panel 2 and a face plate 3 of a mortice lock assembly 4 (see figure 4 20 or 5). The patch lock fitting 1 is particularly suitable for use with a frameless glass door panel 2 as illustrated, however the fitting may also be useful with a framed glass door panel. The glass door panel should include a recess adjacent a side edge which is more clearly illustrated in Figure 2.

Referring now to Figures 4 and 5, the patch lock fitting includes a substructure 8 25 formed from a pair of plate members 6, 7. The substructure 8 has a cavity 9 for receiving the mortice lock 4. In the embodiment illustrated the cavity 9 is defined on the sides by a planar portion 10, 11 of each plate member, and defined at an upper and lower end by transverse portions 12,13 of each plate member 6, 7 extending substantially transverse to each planar portion. 579193 6 The transverse portions are best illustrated in figure 2 and are shown in the form of a wall member 12, 13 extending perpendicular to the planar portion 10, 11. Each wall member 12, 13 extends from a front edge 14 of the planar portion 10,11 towards a rear edge 15 of the planar portion 10, 11. Whilst the 5 illustration shows the wall being spaced from the rear edge 15 of the planar portion 10, 11, this is not essential. More specifically, one or each wall 12, 13 could extend to the rear edge 15 of the planar portion 10, 11, however it is generally preferable to leave a gap so as to allow for a zone x which in use is occupied by the glass panel 2 when the patch fitting is in use. This zone x will 10 be further described later in the specification.

Figure 2 illustrates both plate members 6, 7 having each wall 12, 13 extending from the planar portion 10, 11. However, this is not essential. More specifically, an alternative would be for only one of the plate members 6, 7 to include both walls 12, 13 extending from its planar portion 10, 11. Another alternative is for 15 each planar portion 10, 11 to have only one wall 12 or 13 defining an upper or lower end of the cavity 9. Naturally the height of that wall 12, 13 would need to increase so as to maintain the width of the cavity 9.

Figure 2 also illustrates a plurality of bolts 16 that are used to secure one plate member 6 to the other plate member 7. The bolts 16 preferably extend through 20 one plate member 6 to locate in a threaded bore 17 formed in the other plate member 7. It is preferred that the height of each wall 12, 13 be designed relative to the length of each bolt 16 so as to enable each plate member 6, 7 to clamp onto the glass panel. This form of fastening arrangement is only preferred and other forms of fastening are clearly possible. The patch fitting 25 may also include one or more spacers 17, the or each spacer being located in the zone x between the plate members 6, 7 so as to firmly locate the patch fitting 1 in the recess 5. Figure 2 illustrates the patch fitting having five spacers 17, however this number is merely preferred.

The recess 5 formed in the glass door panel 2 may be designed to facilitate 30 retention of the patch lock fitting 1 within the recess 5. In the embodiment illustrated in Figure 2 and 3 the recess 5 is formed with a concave portion 18 which is keyed into by a convex portion 19 of each wall 12, 13 of the plate 579193 7 members 6, 7 (see figure 3) adjacent the rear edge 15. The form of retention arrangement 18, 19 is merely preferred, and other forms of retention formations are possible. More specifically, the retention formation illustrated is associated with the transverse portion 12, 13, however the retention formation may be a 5 separate feature of each plate member 6, 7. It ought to be appreciated that once the plate members 6, 7 are fastened together to form the substructure 8, the patch lock fitting 1 will be retained in the recess 5 and it would be very difficult to forcibly remove the fitting 1 from the recess 5 in a direction parallel with the plane of the glass door panel 2.

The substructure 8 preferably includes at least one threaded bore 21 adjacent to the front edge 14 of the planar portion 10, 11. Each bore 21 receives a bolt 22 for attaching the mortice lock 4 to the substructure 8. This attachment may be a direct attachment of the housing 4 to the substructure 8 as illustrated in figure 5, or an indirect attachment via the face plate 3 as illustrated in figures 2 15 and 4.

Figure 2 illustrates bores 21 formed in upper 13 and lower walls 12 of one plate member 7. This is merely preferred, and the location of the bores may vary. More specifically, as an alternative the bores 21 may be located in an upper wall 13 of one plate member 6 and a lower wall 12 of the other plate member 7.

It is generally preferred that the bores 21 be aligned with the glass door panel 2 so as to centrally align the mortice lock 4 assembly with the glass door panel 2. However, it ought to be appreciated that this alignment is not essential. More specifically, the bores 21 in the plate members 6, 7 could be miss aligned to coincide with miss aligned bores 23 (see fig 2) in the mortice lock housing 4, 25 while still maintaining the mortice lock housing 4 in alignment with the panel 2. Therefore variations in this alignment are possible. Figure 2 however illustrates the apertures 24 in the faceplate 3 being centrally aligned to receive bolts 22 there through for attaching the face plate 3 to the substructure 8. Furthermore figure 2 illustrates the bores 23 in the mortice lock housing 4 being centrally 30 aligned with further apertures 25 in the face plate 3. 579193 Figure 2 also illustrates each planar portion having a recess 26 which in use accommodates a cylinder lock housing 27 of the mortice lock assembly 4. It is preferred that the recess 26 extends from the front edge 14 of the plate member 6, 7 so as to allow the mortice lock housing 4 to be located in and removed from 5 the cavity 9 in the substructure 8 without detaching the cylinder lock housing 27 from the mortice lock assembly 4.

Figure 2 also illustrates the patch lock fitting 1 having a pair of covers 28, each one located over a respective plate member 6, 7. The covers 28 are retained adjacent the plate members 6, 7 by way of grub screws 29 located in each 10 planar portion 6, 7, however this form of fastening is not essential. More specifically the covers may be clipped on or attached using other forms of fasteners. Each cover includes an aperture 30 for providing the user with access to the cylinder lock face 31. The cylinder lock face 31 may protrude into or through the aperture which will further increase the resistance of the mortice 15 lock housing 4 from being pulled out of the patch lock fitting 1.

It ought to be appreciated from the description above that the invention provides a patch lock fitting 1 that allows the mortice lock assembly 4 to be substantially aligned with the plane of the glass door panel 2. Securely fixing of the mortice lock assembly 4 to the patch lock fitting 1 is a further advantage.

Various alterations and/or additions may be introduced to the patch lock fitting as hereinbefore described without departing from the spirit or ambit of the invention.
