S&F Ref: P004325 AUSTRALIA PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT Name and Address Architectural Window Systems Pty Ltd, of Applicant: an Australian company, ACN 067 950 903, of 76-78 Jedda Road, Prestons, New South Wales, 2170, Australia Actual Inventor(s): Mark McCleary Address for Service: Spruson & Ferguson St Martins Tower Level 35 31 Market Street Sydney NSW 2000 (CCN 3710000177) Invention Title: An assembly to support a lock Associated Provisional Application Details: [33] Country: [31] Appl'n No(s): [32] Application Date: AU 2010903818 25 Aug 2010 The following statement is a full description of this invention, including the best method of performing it known to me/us: 5845c(5422888_1) 1 AN ASSEMBLY TO SUPPORT A LOCK Technical Field [0001] The present invention relates to assemblies to support locks in doors and more particularly but not exclusively to such assemblies including an extruded generally upright door frame member that receives the lock. Background of the Invention [0002] Frequently pivotally and sliding mounted doors include a door frame that receives a panel. Typically the panel would be one or more glass sheets. [0003] The door frame includes a pair of generally parallel transversely spaced upright frame members joined by a pair of generally parallel transversely spaced horizontal frame members. Accordingly the frame is of a generally square or rectangular configuration. One of the vertical frame members receives a lock that engages the door jamb. [0004] To correctly install the lock, the vertical member that receives the lock has machined in it an aperture through which the lock is inserted. The aperture is formed by a tool that is rotated. Accordingly the corners of the aperture are curved. [0005] A disadvantage of the above described door frame member and associated lock is that the face plate of the lock needs to be formed so as to match the rounded corners of the aperture, or the aperture further machined to remove the rounded corners. Frequently a lock with a non standard face plate needs to be provided. [0006] The locks are secured to the vertical frame member by having located within the frame member a plate engaged by a threaded fastener. The threaded fastener passes through an aperture in the face plate and passes through the frame member to engage the plate. When installing the lock, frequently it is difficult to engage the plate as the plate is not well located. Accordingly, a disadvantage of this method of installing locks is time consuming and therefore costly.

2 Object of the Invention [0007] It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages. Summary of the Invention [0008] There is disclosed herein an assembly to support a door lock, the lock having at least one aperture through which a fastener passes to secure the lock to the assembly, the assembly including: an extruded door frame member, the member including an outer longitudinally extending surface having an aperture through which the lock is inserted to project inwardly of the member, the member having a pair of longitudinally extending transversely spaced slots located inwardly of the member from said surface; a mounting member located in the slots adjacent the aperture of the outer longitudinally extending surface and adapted to engage the fastener so that upon tensioning of the fastener the lock is secured to the assembly; and at least one filler part to engage the lock, the at least one filler part having a mounting portion disposed between the lock and the mounting member, and an exposed portion located at an end extremity of the aperture of the outer longitudinally extending surface. [0009] Preferably, the door lock has a pair of apertures, said pair of apertures of the door lock being longitudinally spaced relative to the assembly, and said mounting member is a first mounting member, and the assembly includes a second mounting member, the second mounting member being located in said slots and located adjacent a respective one of the apertures of the door lock but spaced from the first mounting member and adapted to engage a second fastener to pass through the respective one of the apertures of the door lock to further aid in securing the lock to the assembly. [0010] Preferably, the mounting members are slidably mounted in the slots. [0011] Preferably, said assembly includes at least one locating part, the at least one locating part being attached to the frame member and engages with an associated one of the mounting members to aid in locating the associated mounting member relative to the aperture of the outer longitudinally extending surface.

3 [0012] Preferably, said slots are a first pair of slots, and said frame member includes a second pair of slots, with the assembly further including a strip located in said second pair of slots. [0013] Preferably, the strip is slidable along the second pair of slots. [0014] Preferably, the exposed portion of the filler part is substantially flush with the outer longitudinally extending surface. [0015] Preferably, the lock includes a face plate and said aperture of the door lock extends through the face plate, and wherein the fastener passes through the face plate, the mounting portion of the filler part and the mounting member to secure the lock to the assembly. Brief Description of the Drawings [0016] A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein: [0017] Figure 1 is a schematic front elevation of a door lock and a vertical door frame member within which the lock is mounted; [0018] Figure 2 is a schematic front elevation of the door frame member of Figure 1 with the lock removed; [0019] Figure 3 is a schematic parts sectioned plan view of portion of the door frame member of Figure 1; and [0020] Figure 4 is a schematic further sectioned top plan view of the door frame member of Figure 1. Detailed Description of the Preferred Embodiment [0021] In the accompanying drawings there is schematically depicted a lock 10. In this embodiment the lock 10 is mounted on a pivotally mounted door including a generally upwardly oriented frame member 11. The frame member 11 is preferably an extruded aluminium section 4 and includes a surface 12 that provides the edge of the door. The lock 10 is mounted in the member 11 so as to project internally of the member 11. [0022] The lock 10 has a face plate 13 with its exposed outer surface 23 generally co-planar with the surface 12. To enable the lock 10 to be mounted in the member 11, the member 11 is machined so as to provide an aperture 14 through which the lock 10 is inserted. The aperture 14 would be formed by a rotatably driven tool and therefore has arcuate end portions 15. The member 11 is further machined so as to have an inner aperture 16 again enabling the lock 10 to project internally of the member 11. [0023] As best seen in Figures 3 and 4, the member 11 is provided with a pair of longitudinally extending parallel spaced slots 17 that are positioned and configured to slidably receive and retain a pair of mounting members 18. One mounting member 18 is located essentially below the lock 10 while the other mounting member 18 is located essentially above the lock 10. [0024] Also as best seen in Figures 3 and 4, the member 11 has a second pair of longitudinally extending slots 19. The slots 19 receive a longitudinally extending plastics strip 20 part of which is located above the lock 10 while part is located below the lock 10. [0025] Passing through the strips 20 is at least one locating part. In the embodiment depicted, the locating part is in the form of threaded fasteners 29 that project internally of the member 11 and engage the members 18 to accurately locate the members 18 relatively to the aperture 14. The members 18 have apertures that are aligned with apertures 21 in the plate 13 through which threaded fasteners 22 pass to engage the members 18. Tensioning of the threaded fasteners 22 securely clamps the lock 10 in position. [0026] Located between the face plate 13 and the edges of the apertures 14 there is located a filler part 25 that include an exposed portion 26 that is located between the face plate 13 and the edges of the aperture 16 having the curved portions 15. The filler part 25 also has a flange 27 that is sandwiched between the face plate 13 and the member 11 while also having an aperture 28 through which the threaded fastener 22 engaging the member 18 passes. The part 25 also has a projection 30 that aids in retaining the part 25 in position until the fastener 22 is inserted. The fastener 29 can also be employed to engage the projection 30 to aid in retaining the part 25 in position.

5 [0027] The above described preferred embodiment has a number of advantages including enabling locks, having a face plate with square ends, to be used with a filler located between the face plate and the extruded vertical door frame member. Still further the engaging members are retained in position in the vertical frame member so that they are easily engaged when installing the lock.
