S&F Ref: 662803 AUSTRALIA PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT Name and Address Azuma Design Pty Limited, of Applicant: an Australian company, ACN 002 031 307, of 160 162 Newton Road, Wetherill Park, New South Wales, 2164, Australia Actual Inventor(s): Michael Brian Alchin Address for Service: Spruson & Ferguson St Martins Tower Level 35 31 Market Street Sydney NSW 2000 (CCN 3710000177) Invention Title: A striker assembly for a door lock ASSOCIATED PROVISIONAL APPLICATION DETAILS [33] Country [31] Applic. No(s) [32] Application Date AU 2004900034 05 Jan 2004 The following statement is a full description of this invention, including the best method of performing it known to me/us:- -1 A STRIKER ASSEMBLY FOR A DOOR LOCK Technical Field The present invention relates to strikers to be fixed to a doorjamb and engaged by a lock tongue, the lock being mounted on a door associated with the doorjamb. s Background of the Invention Both sliding and pivotally mounted doors are provided with a lock having a tongue, with the tongue being adapted to engage a striker to retain the door in the closed position. The striker is attached to the doorjamb. For the lock tongue to correctly engage the striker, there needs to be an accurate 1o location of the striker and lock. Obtaining this correct location it is often time consuming and difficult. This is particularly evident in sliding doors where the doors are adjustably mounted on rollers. Object of the Invention It is the object of the present invention to overcome or substantially ameliorate 15 the above discussed problems. Summary of the Invention There is disclosed herein a striker assembly to be engaged by a door lock, said assembly including: a base to be adjustably fixed to a door jamb, the base including an upwardly 20 extending central portion with opposite upper and lower ends with a projection at each end, and first apertures through which threaded fasteners are to pass to attach the base to the doorjamb, the first apertures being vertically elongated to provide for vertical adjustment of the base relative to the doorjamb; and a striker member located between the projections and adjustably fixed to the base 25 and to be engaged by a tongue of the lock, and wherein the assembly has second apertures through which threaded fasteners pass to fix the striker member to the base, the second apertures being horizontally elongated to provide for horizontal adjustment between the striker member and base. Preferably, the projections extend horizontally laterally from the central portion. 30 Preferably, said base has said second apertures.

-2 There is further disclosed herein a striker assembly to be engaged by a door lock, said assembly including: a base to be fixed to a door jamb and having elongated first base apertures enabling generally vertical adjustment of the base relative to the jamb; and 5 a striker member fixed to the base but adjustable relative thereto in a generally horizontal direction, and to be engaged by a tongue of the lock, wherein said base includes an upwardly extending central portion with opposite upper and lower ends with a laterally extending projection at each end, said member being located between the projections for movement relative to said base, and said striker 1o member is attached to said base by means of threaded fasteners, with the base having elongated second base apertures through which fasteners pass to provide for horizontal adjustment of the member relative to the base. Preferably, said second base apertures are elongated horizontally. Preferably, said base and member are provided with abutting surfaces that have is engaging ridges and troughs to inhibit relative movement between the base and member when the threaded fasteners are tensioned. Preferably, the first base apertures are vertically elongated to provide for vertical adjustment of the base relative to the doorjamb. Brief Description of the Drawings 20 A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein: Figure 1 is a schematic front isometric view of a door striker assembly; Figure 2 is a schematic front isometric view of the door striker assembly of Figure 1 with a cover member removed; 25 Figure 3 is a schematic parts exploded perspective view of the striker assembly of Figure 1; Figure 4 is a schematic front isometric view of a modification of the striker assembly of Figure 1; Figure 5 is a schematic isometric view of the striker assembly of Figure 4 with a 30 cover member removed; and Figure 6 is a schematic parts exploded perspective view of the striker assembly of Figure 4.

-3 Detailed Description of the Preferred Embodiments In the accompanying drawings there is schematically depicted a striker assembly 10 to be attached to a door jamb to engage the tongue of a lock mounted on the door operatively associated with the doorjamb. In this particular embodiment, the striker 5 assembly 10 is adapted to engage the "hook" tongue of a sliding door lock. However, it should be appreciated that the present invention is also applicable to strikers for pivotally mounted doors. The assembly 10 includes a base 11 to be fixed to the door jamb. The base 11 includes a central portion 12 at the upper and lower ends of which there is provided 1o projections 13. The projections 13 project horizontally laterally beyond the portion 12. The projections 13 are provided with apertures 14 through which threaded fasteners may pass to secure the base 11 to the door jamb. In this respect, it should be appreciated that the apertures 14 are vertically elongated so that the base 11 may be adjusted in height relative to the door jamb and therefore the door and lock fixed thereto. is Attached to the base 11 so as to be positioned between the projections 13 is a striker member 15. The striker member 15 has an aperture 16 with upper and lower edges 17 over which the "hook" tongue can engage. The member 15 has an abutment face 18 to engage a corresponding abutment face 19 on the central portion 12. Preferably, the faces 18 and 19 are roughened or provided with ridges and troughs so that when the striker 20 member 15 is attached to the base 11, the surfaces 18 and 19 inhibit relative movement between the member 15 and the base 11. The central portion 12 is also provided with apertures 20 that are horizontally elongated and through which threaded fasteners 21 pass to engage threaded passages 22 in the member 15. When the threaded fasteners 21 are tensioned, the member 15 is held 25 in position between the projections 13. The member 15 can be adjusted by loosening the fasteners 21 and moving the member 15 relative to the base 11. When a desired position is located, the threaded fasteners 21 are tensioned so that the faces 18 and 19 are firmly held in frictional engagement. A cover member 23 is secured to the base 11 by means of a threaded fastener 24 30 by passing through aperture 25 to engage threaded passage 26 in the base 11. The cover member 23 covers the threaded fasteners 21, and apertures 14 and 20.

-4 In the embodiment of Figure 3, the member 15 is provided with slots 27 into which projections of a sliding door lock would engage to inhibit lifting of the sliding door to remove the hook from engagement with the member 15. In the embodiment of Figure 10, the striker member 15 has apertures 16 and 5 edges 17 over which a hook or hooks of the associated lock would engage.
