DOOR

Details of Associated Provisional Application(s): No(s): Australian Provisional Application No. 2005905221 Filed: 22 nd September, 2005 The following statement is a full description of this invention, including the best method of performing it known to us: Fc2006-9-2 IZA\Filingokaway file wpd, -la- TITLE: SAFE CONSTRUCTION FOR SWING AND SLIDE DOOR FIELD OF THE INVENTION This invention concerns security door and frame construction and relates primarily to safes but is applicable to security doors.

BACKGROUND OF THE INVENTION In our co-pending application for Patent No. 2003252867, we describe security door constructions of the swing and slide type. The door frame has an upright for supporting Fc2006-09-21 .Z:Specificationsokaway.cap3-au wpd.

the door on an offset hinge and the upright of the frame opposite the hinge has a slot capable of receiving the closing edge of the door, which upon closing slides into the slot and upon opening, slides out of the slot.

The slide motion of the door precedes the opening swing and it is this retraction of the door from the slot which intruders try to achieve. The door is free to slide on the hinges and must be retained in the locked position by door bolts. We describe hook and slot formations in the above application which resist prying forces applied to the door. In copending Australian application no. 2004231234, we describe a horizontal bar which slides across the width of the door when the safe is locked and abuts the safe wall adjacent the door hinge. Prying forces tending to slide the door open are transmitted to the safe wall and resisted.

In co-pending Australian application no. 2005901184, we describe door mounted rise and fall hooks which drop into vertical slots in the closing stile of the door frame when the door is locked. These are both effective measures for resisting forces exerted by prying bars applied to the door frame, that is between the door and the closing style.

In safes such as gun safes which are made from plate 2-3mm thick, the above devices exert locking force at various sites and the metal between these sites could be bent. It would be desirable to resist prying by increasing the difficulty of inserting the prying bar into the gap between the door and the closing style so that effective leverage cannot be applied.

SUMMARY OF THE INVENTION The apparatus aspect of the invention provides a safe of the swing and slide type having a closing style which provides a landing surface for the safe door and a pocket for housing the closing edge of the door, wherein the door has a outwardly turned closing edge for the purpose of denying access to the door edge by a pry tool inserted between the door and the closing style.

Fc2006-09-21 Spec ifi~tiomkawy. p3 -au..wpd.2 -3- The closing style may have a portion against which the outward face of the door is intended to abut in the closed position and the pocket has a ramp surface adjacent the landing surface which the closing edge contacts as the door slides to the closed position in which locking follows and passage of the closing edge over the ramp surface forces the front face of the door against the portion of the closing style.

The inclined portion of the slot may have a front inclined wall and a rear inclined wall.

The rear inclined wall acts as a ramp surface contacted by the rear surface of the door edge as the door closes causing the door edge to abut the door stile tightly.

The front inclined wall acts as a ramp surface for the flange, directing the door away from the door stile toward the landing surface when the door is slid open.

The front inclined wall may be formed by bending the free edge of the closing style.

The landing surface may be provided by a wall parallel to the door but projecting from the safe wall adjacent the closing style.

The rear inclined wall may extend from the projecting wall to the closing style.

It is convenient if the rear inclined wall is part of a component of modified channel section which permits reinforcement of the hollow door style. Reinforcement is made possible by giving the component a profile which partly matches the door style profile and during manufacture putting the component inside the channel part of the door style so that the component and channel fit face to face and increase the stiffness of the closing style.

The flange may be formed by bending the door edge and may be 5-15mm deep, preferably 10 Omm deep. In this specification the term "flange" is intended to include a lip made by bending a single plate at 70-90'; a projection at 900 made by fabricating bent sections; a lip with an integral incline which is intended to assist the exit of the door from the door pocket. The flange may be of constant or tapering thickness.

SDETAILED DESCRIPTION WITH RESPECT TO THE DRAWINGS (Ni Referring now to Figures 1 and 2 of the drawings in which the numerals are in sequence Itaken from Figure 1 which represents published art. The door 16 is wider than the gap between the door styles 4, 6. The door is mounted on pairs of hinges 22, 26 and the slide (-i motion LEFT and RIGHT is controlled easily by knob 52, a crank and reaction bar (not shown) as described in Australian application no. 2003966471.

(Ni Referring now to Figures 3, 4 and 5, door style 6 remains the same as in the known safe but closing style is modified and the door closing edge is modified. The door edge is bent away from the safe interior to form a 10mm deep flange 150. The slot 14 is widened to accommodate the flange.

The closing style 4 terminates in a hook section 152, the top of which lies parallel to the landing surface 154. These two surfaces are separated by about 15mm in this embodiment. The corner of the style is strengthened by an angle section 156 and Rshaped section 158 forms a box 160, the landing surface 154 and a ramp 162. The slot shown in Figures 1 and 2 widens to form a pocket 164 extending the full height of the door.

In Figure 3 the rear face of the door 16 when swung on hinge 26 strikes the landing surface 154. When handle 52 rotates, the door swings about hinge 26 and slides toward the close/lock position where the edge of the door is deflected by ramp 162 and is forced against hook section 152 (see Figure Referring now to Figure 6, the door may be hollow and fabricated from plate so that the flange 150 is made from a hook section and an angle section.

Figure 7 shows how the flange of Figure 6 is modified to provide a second or exit ramp 166. When the handle 52 turns to open the door, the flange rides over exit ramp 166 and Fc2006-921,Z: \Specificatio ~okay. cap3 -au. -6slides over the landing surface 154.

In Figure 8 hook section 152 is modified to include the exit ramp 166. In addition, the door is fabricated from plate sections which include an incline 168. Upon commencing to slide open, incline 168 rides up exit ramp 166.

In Figure 9 the hook section 152 is simplified and presents a free edge 170 to the door edge. The flange 150 of the door is modified in that the incline 168 is provided in the door instead of being part of the portion of the closing style. The incline subtends an obtuse angle with the front face of the door.

The strips of foam 171 in Figure 9 and the earlier Figures are fire seals which react to fire by swelling in volume and closing the gap between the metal surfaces of the safe.

In Figure 10 the ramp surface 162 is modified in that it leads to a seat 172 about wide against which the corner of the external comer of the door 16 rests when closed and locked. The front face of the door abuts the hook formation 152 on the closing style.

Both faces of the door make contact with the closing style when the door is closed.

In Figure 1I1 the door is made from bent sections similar to those shown in Figure 6. The hinge end of the door is modified to create a hook formation 174 which cooperates with a complementary hook formation 176 on the opening style. When the door slides to the RIGHT on hinge 26 and then swings around hinge 22, the hook formations separate and allow the door to open about 900.

The modifications in Figures 10 and 11 are intended to resist a frontal force F on the door such as by ramming the centre of the door or the application of an impact tool.

We have found the advantages of the above embodiment to be: 1. An intruder has less purchase with a prying bar because closing causes the door to abut the closing style.

Fc2006-09-2 I.Z:\Spciriom~ lokaMy.up3 au .pd,6 2. The hinges and locking parts need not be as robust to achieve the same resistance to prying.

3. The improvement does not interfere with the installation or operation of conventional components such as pins which shoot in and out of the frame or door hooks which engage slots in adjacent frame components.

It is to be understood that the word "comprising" as used throughout the specification is to be interpreted in its inclusive form, ie. use of the word "comprising" does not exclude the addition of other elements.

It is to be understood that various modifications of and/or additions to the invention can be made without departing from the basic nature of the invention. These modifications and/or additions are therefore considered to fall within the scope of the invention.
