DANDENONG VIC 3175 METHOD APPARATUS FOR ERECTING A DOOR Details of Associated Provisional Application(s): No(s): Australian Provisional Application No. PL8940/93 The following statement is a full description of this invention, including the best method of performing it known to me/us: 1 CO 1 33 0 2 iiAW 94 940,crsdat.197,hyandxcap,1 _I I I_ la- TITLE: METHOD AND APPARATUS FOR ERECTING A DOOR FIELD OF THE INVENTION This invention relates to a method and apparatus for erecting a door.

BACKGROUND TO THE INVENTION It is common to provide security doors comprising a door frame having a top and bottom rail, two stiles and a panel extending in between the rails and the stiles.

The panel is usually made of metal mesh.

On a simple cost and strength basis, a steel security door is superior to an aluminium security door.

However, notwithstanding that standards exist, and that 20 doors can be purchased of a standard size, it is commonly found that a door manufactured to a standard size will not *fit to a door frame which is supposedly of a standard size.

In the case of timber doors it is relatively easy to cut a standard door or to plane it or to tack a strip onto it to suit a non-standard door frame.

In the case of the steel security door, such options as cutting, planing or adding a piece on are not particularly practicable.

Accordingly, if a steel door is to be made, it is current practice for a workman to visit the actual site and make measurements. Thereafter, the door is made to those measurements and inevitably a delay occurs particularly if a quality security door is required which has been given good quality rust proofing and powder coating.

940M23,crnsspe.074,HYIAND.CAP,1 2 Aluminium at present appears to have an advantage in respect of metal security doors in that it can be readily cut with simple tools and assembled into a door on site.

Whilst steel can be similarly worked, it is not practicable to provide freshly cut ends of steel with good quality rust proofing on site.

Accordingly, at present, an aluminium security door offers certain savings in labour costs as compared to a steel security door.

However, on the basis of quality and strength, a steel security door is still to be preferred.

Accordingly, the applicant, recognising that it takes a significant period of time to measure, make, electroplate, powder coat and install a steel door, has sought for ways in which a steel door might more easily be installed, and 20 fully meet all the requirements of and pass Australian Standard AS/NZS 2803 in respect of security doors.

SUMMARY OF THE INVENTION The present invention provides an adjustable metal security door comprising:a longitudinal extending metal hinge post having two or more security hinges mounted on said hinge post so as to be attached by said hinges to a side of a doorway frame, a metal door frame being engageable with the longitudinally extending metal hinge post, said door frame comprising a top rail, a bottom rail, a lock or latch stile adapted to locate adjacent to a lock or latch side of the doorway frame, a second stile on the opposite side to the lock or latch stile and a panel extending between the rails and /stiles, the outer edge of said second stile constituting a 960731 pnsdat.092D'!and~cp2 3 longitudinally extending channel member engageable over the hinge post so as to be adjustable thereon and fixable thereto to vary the width of the door.

The present invention also provides:a method of fitting an adjustable metal security door to a doorway frame which doorway frame comprises a first upright to which the door is to be hinged and a second upright towards which the door is to hingedly swing and to which the door is to latch or lock; comprising hingedly mounting a longitudinally extending metal hinge post to the first upright, taking a metal door frame comprising top and bottom rails, two spaced stiles and a panel extending between the rails and the stiles, fitting said metal door frame on said longitudinally extending metal hinge post by means of a channel member forming one of said stiles engaging over said hinge post and adjusting and fixing the position of said metal door frame with respect to said longitudinally extending hinge post whereby to vary the width of the combination of said longitudinally extending hinge post and said door frame.

PREFERRED ASPECTS OF THE INVENTION The door and the longitudinally extending member may be secured together with the longitudinally extending metal hinge post already hinged or prior to final hinging as suits a person.

Preferably there is a means for effecting widthwise 960731,ansdat.92,hyandcap3 4adjustment and another means for holding to a particular widthwise adjustment.

In a preferred instance, screws are used for effecting widthwise adjustment and bolts are used to hold to a particular widthwise adjustment.

In using screws to effect adjustment it is to be noted that gravity acting on the door will tend to cause a turning away from the longitudinally extending hinge post towards the top of the door and a turning towards the longitudinally extending hinge post towards the bottom of the door. This can be counteracted by using an upper screw tending to pull the door and longitudinally extending hinge post together and a lower screw tending to push the door and longitudinally extending hinge post apart.

In another instance the longitudinally extending hinge post and the door frame are so shaped that they press-fit '20 together in a series of steps to effect the desired adjustment.

In another instance a ratchet mechanism is used to obtain adjustment.

As it is possible that there may need to be a height adjustment of the door it is preferred to provide a height S: adjusting member.

The height adjusting member may be a panel which can be fixed to one of the rails.

In a preferred instance the height adjusting member is in use secured to the top rail.

In a preferred instance the height adjusting member is a channel which can locate over the top rail.

While the present invention has particular application to the manufacture of steel doors it can also be used in respect of aluminium doors.

A specific embodiment of a door in accordance with this invention will now be described with the aid of the accompanying drawings.

The door 1 shown in the drawings comprises a hinge post 2 20 which is provided with hinges 3.

The hinge post 2 is formed of 50 x 20 x 1.6 mm tube.

The hinges 3 are in the nature of butt hinges and are known steel security hinges incorporating interlocking lugs or dogs 3a which prevent dismantling of the hinge plates on removal of the hinge pin and such hinge construction is hereinafter referred to as "security hinges".

Attached to the hinge post 2 in a manner to be described below is a frame 4.

The frame 4 comprises a top rail 21 and a bottom rail 22.

The rails 21 and 22 are formed of 50 x 20 x 1.6 mm steel tube.

960731,cmsdat.092,hyland.cap,6 6 a- The frame 4 further comprises an upper strengthening bar 23 and a lower strengthening bar 24.

V. V 960731.cmsdat.092.hylandxeap,6 7- The strengthening bars 23 and 24 are made of 25 x 5 mm mild steel.

Panels of mesh 26 are provided and may be a measure o£ any desired strength or style. One suitable mesh is Lysaght HH 3050. Another suitable mesh is Lysaght PA 051 which is a restricted vision mesh.

Extending between the bars 23 and 24 is an anti-tamper plate 27.

A lock 28 is secured to a right stile 31.

The lock 28 is of a nature which has a thumb turn release on the inside but a key release on the outside. It is considered important to have a thumb release on the inside for safety reasons in case of fire.

In addition, the frame 4 comprises a left stile 32.

The right stile 31 is formed of 50 x 20 x 1.6 mm steel tube.

The left stile 32 is a roll form section 50 x 25 x 1.6 mm which is in fact a channel 33 as can be seen in Figures 2 and 3.

4. e The channel 33 comprises a web 34 and flanges 36. The channel 33 has an open side 37 within which the hinge post 2 is received.

It will be appreciated that the frame 4 by being entered S. around the hinge post 2 can be moved towards and away from the hinge post 2 and, as a result, the width of the door 1 overall can be varied by the amount which the open side 37 is moved onto the hinge post 2.

94l523,cmsspe.074,HYLAND.CAP,7 8 For the purpose of making a specific width adjustment, a top adjustment screw 38 and a bottom adjustment screw 39 are provided.

The screws 38 and 39 pass through the web 34 and screwingly engage with the hinge post 2 thus by tightening or loosening the screws 38 and 39 the proximity of the web 34 and hence the effective width of the door 1 can be varied.

In use, the door is offered up to a frame and adjustment is made to the screws 38 and 39 until the door 1 suitably fits the frame.

It is to be noted that the screw 38 is arranged to tend to pull between the post 2 and channel 33 while the screw 39 is arranged to tend to push between the post 2 and channel 33.

Thereafter, fixing bolts 41 pass through the flanges 36 and through the hinge post 2 and are tightened up to fix the positional relationship of the hinge post 2 and channel 33.

Since some adjustment of the height of the door 1 may be necessary, a cap 46 is provided.

The cap 46 is a rolled formed section 22 x 40 x 1 mm.

As necessary, the cap 46 may be cut to length on site.

The cap 46 fits over the top rail 21 although it could also fit below the bottom rail 22, and it secured to the top rail 21 by means of pop rivets 47.

The door 1 described above is believed to have ample adjustment to suit non-standard door frames, can be prior manufactured to be ready for installation on site without the need for prior measurement and subsequent manufacture, 940523,mssp.074,HYLAND.CAP,8 9 can be despatched to country areas provided some minimal information is known about size requirement, can still have good quality rust prevention treatment and should be closely as readily installable as an aluminium door.

Still further, it is noted that the door 1 could possible be re-used at another site. In this last respect, it has been noted that steel security doors, because they are normally made to a specific size, are often discarded when a building is demolished or when changes to a building are made. As a consequence, doors which are in perfectly satisfactory condition are often discarded whereas they could be readily be re-used.

The claims, illustrations, photographs and drawings form part of the disclosure of this specification as does the description, claims, illustrations, photographs and drawings of any associated provisional or parent specification or of any priority document all of which are 20 imported hereinto as part of the record thereof.

Finally it is to be understood that various alterations, modifications and/or additions may be incorporated into the various constructions and arrangements bor parts without 25 departing from the spirit and ambit of the invention.
