Class U S TO BE COMPLETED BY APPLICANT Name of Applicant: AFAZE PTY LTD trustee for the SDL UNIT TRUST Address of Applicant: 57 Robinson Avenue, Belmont, in the State c' Australia, Commonwealth of Australia.
Actual Inventors: SAMUEL GEORGE DOAK and CLEMENT JOHN LONGMAN Western Address for Service:- Wray Associates Primary Industry House 239 Adelaide Terrace Perth Western Australia 6000.
Complete Specification for the invention entitled: "AN IMPROVED SECURITY DOOR SYSTEM" t The following statement is a full description of this invention, including the best method of performing it known to us:- Ci 1 i 13 THIS INVENTION relates to an improved security door system and parts thereof in order to prevent unauthorised entry into a building.
With the ever increasing consciousness of the community insofar as security of one's home is concerned, a Ssubstantial market has developed in Australia in respect of security doors. Accordingly, a number of Australian Standards have been brought into existence in respect of S the manufacture and design of security doors, however, it I has come to light that the Standards are set to such a high ideal, that it is extremely difficult to economically manufacture and market a security door for the domestic i market which meets the Australian Standards. In this S, respect, it has been almost impossible to achieve the Standards without the use of a plurality of locks incorporated into the design of the door, generally three, one located near the top of the aoor, one near the bott-c '1 and one near the centre of the door.
SFurthermore, it has heretofore been near impossible to 0 design a door which can meet the Australian Standards when fitted to a timber door frame as opposed to a steel door frame.
The three major aspects of the Australian Standards which have in the past proved difficult to achieve in the design of security doors, without requiring the provision of a plurality of locks and utility in respect of only steel door frames, are:- The ability of the door to withstand buckling or collapse along the plane of the door in the transverse direction, which can arise from an intruder jemmying the door near the lock to withdraw the tongue of the lock axially from the receptor hole of the striker plate; i 3 (ii) The ability of the door to oppose prising and bending at the top and especially at the bottom of the door outwardly from its plane whilst the centre portion of the door remains in its locked position, which can arise by an intruder grasping and lifting or pulling the bottom or top of the door which is not locked to the door frame out from the plane of the door to gain access; and (iii) The ability of the striker plate to remain fixed in position to the door frame in the face of high lateral Q s: stresses applied to the door and consequently the tongue of the lock when extended in the locked position within S the receptor hole of the striker plate, as may arise with o o an intruder attempting to prise or jemmy the door out of 2 its locked position.
It is an object of the present invention to provide a security door system having a single lock which is capable i of satisfying the aforementioned requirements specified in the Australian S.-ndards for security doors, and also 4a4 i S( separate componentj of the door system which satisfy one or other of the aforementioned requirements.

The invention will be better understood by reference to the following description of one specific embodiment thereof which is described with reference to the accompanying drawings in which:- Figure 1 is a perspective view of a security door system according to one specific embodiment of this r r -i -II- I i; -6invention; Figure 2 is a cross sectional view of the intermediate rail; Figure 3 is a fragmentary plan view of the peripheral frame of the security door along the longitudinal side adjacent the locking means; and Figure 4 is a fragmentary perspective view of a security door system.
The embodiment is directed towards a security door system and towards the striker plate, intermediate rail and rod 0 components of the system.
The security door system generally comprises: a security door 40 of typical prOportions having a peripheral frame 31 of hollow section, intermediate rail and cylindrical rod 30; and (ii) a striker plate all of which are mounted within and to a door frame 14.
a o:C 0 The peripheral frame 31 of the security door 40 comprises i a pair of spaced apart longitudinal! sides 31a and 31b, and a pair of spaced apart transverse sides 31c and 31Id which are arranged in a rectangular configuration and which are adapted to support a metal grille. One longitudinal side S31a is provided with hinges 32 to be hingedly secured to so that the other longitudinal side 31b can be moved the, IcorreIsponing longitudinal 'side: of the -door. :f rae 14, laterally with respect to the door frame to enable opening or closing of the door. One of the transverse sides 31c is provided at the top of tle door and the other transverse side 31d is provided at the bottom of the door.
The striker plate 10 comprises two faces 11a and llb in a spaced parallel relationship with respect to each other.
The faces I1a and lIb are adjoined at adjacent edges by means of a web portion 12 which extends substantially orthogonally between the faces. The arrangement of the j 7faces and web portion result in a stepped configuration adapted to be fixedly secured to a portion of the door frame 14 by means of screws 18 accommodated within corresponding holes of the striker plate. The striker plate is particularly mounted so that one of the faces llb is juxtaposed to the outer face 15 of the door stop of the door frame 14, the other face 11a is juxtaposed to the outer face 13 of the door reveal, and the web portion 12 is juxtaposed to the anterior face 19 of the door stop.
The face lla which is juxtaposed to the outer face 13 of the door reveal is provided with an aperture 16 in the 0 0 0 form of a rectangular hole through which locking means in the form of an extendable and retractable tongue 17 0 e :provided on the door, is received.
The intermediate rail 20 comprises an elongated hollow section 21 of rectangular uniform cross-section. The 0 hollow section 21 is provided with a pair of U-shaped ro, channel members 23a projecting vertically from opposite 0° sides of the hollow section and extending along the 0°20 longitudinal axis thereof.
Each channel member 23a is adjoined to the hollow section 21 by a web portion 22a. Each channel member 23a is spaced apart and parallel to the hollow section 21.
The intermediate rail 20 is disposed on the surface of a I with the locking means to support the same, which position is generally within four inches of the midway line between and parallel to the transverse sides of the frame 31 of the security door.
The rod 30 is cylindrical and has a uniform circular cross-section. The rod 30 is comprised of a high tensile steel which is substantially resilient to lateral bending _1 _i -8moments and extends within the hollow peripheral frame 31 of a security door 40 along a longitudinal side of the frame which is adjacent to the locking means 17. The opposite ends of the rod 30 terminate at positions A spaced a distance apart from the transverse sides of the frame.
The frame 31 of the door is provided with a U-shaped channel member 23b affixed to the frame by the provision of a web portion 22b along one side of the channel member 23b which is identical in configuration to the channel members 23a and extension 22a provided on the intermediate rail SThe U-shaped channel members 23a of the intermediate rail j %i 20 and channel members 23b of the frame 31 are interconnected to form two rectangular sub-frames spacee.
vertically apart to receive two panels of metal grille 41.
One panel is positioned above the intermediate rail 20 and the second is positioned below the intermediate rail 20 as shown in Figure 1.
L} 0 The purpose of the intermediate rail 20 is to provide additional and sufficient transverse strength to the security door 40 so as to oppose buckling of the 4 longitudinal sides 31a and 31b towards each other in the plane of the door, and so inhibit jemmying of the locking means 17.
The cylindrical rod 30 is provided to strengthen the other longitudinal side 31b of the security door 40 in order to prevent or reduce the likelihood of the top or bottom transverse sides 31c and 31d of the frame of the security door from being permanently prised up, thereby preventing unauthorised entry or inhibiting access through said security door.
-9- By having the striker plate 10 formed of a stepped configuration a stronger mounting of the striker plate to the door frame can be achieved, thereby reducing the likelihood of the security door 40 from being forced open by prising the striker plate 10 from the door frame 13.
More specifically the additional strength is provided by the face lib of the striker plate 10 being juxtaposed to the outer face of the door stop portion 15, as well as to the door reveal. Consequently, this form of striker plate I 10 makes the security door system capable of being fitted to wooden door frames and still satisfy or approach the .a Sspecifications set down by the Australian standards.
The security door system may also be provided with flywire 9. 42 and suitable handle means for operating the locking means.
Various other changes and modifications may be made to the embodiment described without departing from the spirit and "scope of the invention.
