According to a third aspect of the present invention, there is provided a cabinet comprising said assembly, wherein the closure is a door or cover of the cabinet. 25 In a preferred embodiment of the invention, the assembly includes a protective holder for a padlock configured such that when the padlock is held thereby, the holder and padlock form an assembly for releasably interlocking said closure and said structure ("lock assembly"), the holder having a housing which is configured to be supported from or forms part of one of said closure and said structure so as to be able to receive, upon sliding 30 movement of said closure, relative to said structure, into a closed condition, a catch supported from or forming part of the other of said closure and said structure whereby to C:\Users\sbt\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -2- permit receipt of the catch through the space defined within the shank of the held padlock when open, the housing being configured with an opening whereby the body of the held padlock is accessible in a manner such that the body can be pushed to effect closure of the held padlock and thus entrapment of the catch once received through the space, whereby 5 said closure and said structure are interlocked, and such that opening of the held padlock can thereafter be effected, whereby the catch and lock assembly are separable, the holder further comprising a retainer received by said space so as to engage the shank and so hold the padlock in position in the lock assembly. A conventional padlock, to which this embodiment has particular, but not exclusive, application, comprises a metal body, an 10 inverted U-shaped shank coupled to the body, and a tumbler or core, which is housed in the body and configured with a key slot that accessible through a base of the body to receive a key for unlocking the padlock. The padlock in this embodiment is thus shielded when it is in use, whereby a person, for the purposes of gaining forced entry or access, is hindered or precluded from breaking it, e.g. using an oxyacetylene torch to melt the body 15 or shank of the padlock, or using bolt cutters to break the shank, or by drilling through the tumbler in the body.

In preferred embodiments of the invention, the protective holder is a lockbox which houses a padlock to preclude access to the shank thereof, protecting it from damage inflicted in an 20 attempt to break the lock when in use.

Preferably, the housing is formed from stainless steel. The housing may be formed of an alternative material - preferably metal - but preferably one which is likewise unable to be cut, or at least difficult to cut, with an oxyacetylene cutting torch. 25

In preferred embodiments of the invention, the retainer precludes removal or escape of the padlock through the opening in the lock assembly.

Preferably, the housing comprises opposed front and rear walls, between which the 30 padlock in the lock assembly lies and which face a front and rear, respectively, of the padlock in the lock assembly, a top wall, below which the padlock in the assembly lies, C:\Users\sbt\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -3- and opposed side walls, between which the padlock in the lock assembly lies and which face lateral sides of the padlock in the lock assembly, and the opening is bounded by lower ends of the front and rear walls and side walls. 5 Preferably, the holder is configured such that the padlock hangs from the retainer -preferably in a substantially upright orientation - in the lock assembly. Preferably, the opening is through a lower end of the housing. Preferably, the opening is downwardfacing. Preferably, the retainer comprises a hanger. 10 Preferably, the retainer is shaped to conform to the inner profile of the shank, whereby engagement between the retainer and shank locates the padlock in the lock assembly.

Preferably, the housing is configured with an aperture arranged to receive the catch therethrough. Preferably, the retainer projects into the aperture. 15

Preferably, the housing includes a cover which can be removed such that mounting of the padlock in the housing and removal of the padlock from the housing are permitted. Preferably, the aperture is formed through the cover. Preferably, the cover is defined by a front wall of the housing. Preferably, the cover comprises a cover plate. 20

Preferably, the housing is configured with opposed interior faces which lie closely adjacent front and rear sides of the shank in the lock assembly such that an extent to which the shank is displaceable along the retainer is limited or negligible. Preferably, the faces are defined by spacer pieces projecting into the housing interior from front and rear walls of 25 the housing.

Preferably, the housing is configured with opposed interior faces which lie closely adjacent front and rear sides of the body in the lock assembly such that an extent to which the body is displaceable in a direction from either one of those sides to the other is limited or 30 negligible. Preferably, those faces are defined by front and rear walls of the housing. C:\Users\sbt\AppData\Local\Microsoft\Windows\Teinporary Internet Files\ContentOutlook\P9411D5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -4-

Preferably, the housing is configured with opposed interior faces which lie closely adjacent opposite lateral sides of the body in the lock assembly such that an extent to which the body is displaceable in a direction from either one of those sides to the other is limited or negligible. Preferably, those faces are defined by side walls of the housing. 5

The padlock is preferably one which is key-unlockable. Generally speaking, the key-unlockable padlock will be one which has a key slot accessible through the base of the padlock body. Alternatively, the padlock may, for example, be a combination padlock, configured with means (such as a dial, discs or cams) for inputting a sequence of letters or 10 numbers to open the lock.

Preferably, the closure comprises a door or cover.

In a preferred embodiment of the invention, the closure is said sliding closure and said 15 structure comprises a section which is positioned to abut or lie closely adjacent a leading edge of the closure when the latter is in said closed condition, and said holder is recessed within said section so as to be rendered inaccessible by movement of closure into the closed condition. Preferably, said section is defined by a frame member, which may, for example, form part of a support frame of the closure assembly. The support frame may be 20 a fixed frame or form part of another closure of the closure assembly. The other closure may be a slidable closure having a leading edge which, when both closures are in closed conditions, abuts or lies closely adjacent the leading edge of said sliding closure.

Preferably, the holder is arranged to one side a wall of said one of the closure and structure 25 and an opening is provided through the wall at a position adjacent the holder, permitting access, from the other side of the wall, to the opening of the holder to lock and unlock the padlock in the lock assembly. Preferably, the opening of the holder is transverse to the opening provided in the wall. Preferably the padlock hangs from the retainer in the lock assembly, the opening of the holder is downward-facing, and the opening provided through 30 the wall is at a level below that of the opening of the holder. Preferably, the releasably lockable assembly includes a guard or shroud which opens into the opening provided C:\Users\sbt\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -5- through the wall and also opens into the opening of the holder, defining a cavity into which a person may insert digits of his or her hand to lock or unlock the padlock, which isolates one side of said one of the closure and structure from the other side of said one of the closure and structure. 5

CAUsers\sbt\AppData\Local\Microsoft\WindowsYTeniporary Internet Files\Content.Outlook\P9411 D5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -6- A lockbox 1 is illustrated in Figures 1, 2, 3 A and 3B. The lockbox 1 comprises a housing 3 which receives a padlock 50 (see Figure 3A), the housing 3 being generally box-shaped and having opposed side walls 3A, a top wall 3B, a rear wall 3C, and a removable cover 3D defining a front wall of the housing 3, the "front" being the position at which the 5 lockbox 1 is opened. The cover 3D is removably attachable to the remainder of the housing 3 via screws 4A which are received through holes 4B formed in the cover 3D at upper comer positions thereof, and into threaded holes 4C provided at corresponding comer positions in or adjacent to the rear wall 3C. The walls 3A, 3B, 3C and 3D are formed from sections of stainless steel plate. 10

The cover 3D is configured with an aperture 5, which receives therethrough a catch, as will be described in further detail later.

As can be seen in Figure 2, the rear wall 3C comprises two plate sections, whereby it is 15 very robust, namely an outer plate section 3C1 and an inner plate section 3C2 which is welded thereto, into upper corner portions of which inner section the threaded holes 4C are formed. The inner plate section 3C2 is formed with an aperture 6 therethrough which aligns with the aperture 5 when the cover plate 3D is in position and defines a forwardly opening recess behind the padlock 50 (when mounted in the holder 1), which receives the 20 catch, as will be described in further detail later. The rear wall 3C is provided with an inverted U-shaped piece 3C3, also cut from plate, which is welded to the inner plate 3C2, so as to project therefrom into the housing interior, and is formed with cutouts 9 at the upper comer positions thereof, which permit access to the threaded holes 4C. 25 The wall 3D comprises a single plate section 3D1 formed with cutouts 8 at the upper comer positions thereof, and also is provided with an inverted U-shaped piece which is welded to the section 3D1 so as to project into the housing interior when the cover plate 3D is in position. The holes 4B are formed through corners of the section 3D2 which are exposed through cutouts 8, whereby the heads of the screws 4A are recessed behind the 30 outer face of the cover 3D when in position. The sections 3D2 and 3C3 are arranged so as not to occlude the apertures 5 and 6. C:\Users\sbt\AppData\Local\Microsoft\Windows\Teniporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -7-

The lockbox 1 additionally comprises a retainer 7 which is fixed to the rear wall 3C/piece 3C3 and projects forwardly to be received through the space 52 bounded by the shank 54 of the padlock 50, whereby the padlock 50 hangs from the retainer 7 when 5 mounted in the lockbox 1. The retainer 7 is configured in the form of an inverted U-shaped section, which is bent from plate so as to conform generally to at least part of the curved inner profile of the shank 54 at its upper end, thereby defining a saddle which locates the upper end of the shank 54 and against which that upper end seats (see Figure 8). The spacing between the uppermost extent of the retainer 7 and the upper wall 3B is only 10 slightly larger than the thickness of the shank 54, whereby there is minimal clearance between the shank 54 and upper wall 3B when the padlock 50 is mounted. The spacing between the walls 3A is only slightly larger than the width of the padlock body 56, whereby there is minimal clearance between the body 56 and the respective side wall 3 A on either side of the body when the padlock 50 is mounted. The shape of the retainer 7 is 15 such that it permits padlocks 50 having different sizes of shank 54 to be hung therefrom in a self-locating manner; the upper end of a shank having a relatively large radius of curvature will be contacted along a relatively short arcuate portion thereof by the curved upper surface of the retainer 7, whereas one which has a relatively small radius of curvature will be so contacted along a relatively long arcuate portion thereof, by the curved 20 upper surface of the retainer 7. Because the upper surface of the retainer 7 is symmetrical about an upright central plane extending from the front of the lockbox to the rear of the lockbox, the shank 54, which is correspondingly symmetrical, automatically locates when hung on the retainer 7. The shape of the retainer 7 is also such that it precludes a padlock having an excessively small shank from being hung from the retainer 7. 25

Because the retainer 7 is configured in the form of a curved section of thin plate, it occupies only a small amount of the space 52 when received therethrough, thereby allowing for the use of a relatively large-sized, and thus strong, catch with the lockbox 1 and padlock 50, which catch will be described in further detail later. 30

Referring to Figure 3A, the housing 3 has no lower wall, whereby it is configured with an C:\Users\sbt\AppData\Local\Microsoft\Windows\Teniporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -8- opening 9 at its lower end. The opening 9 provides access to the underside or base 57 of the padlock body 56, permitting a key 60 to be inserted into the lock barrel/tumbler key slot which is accessible through the base 57, and thus unlocking of the padlock 50. The opening 9 also permits the body 56 to be pushed upwardly, either via direct contact with 5 the base 57 or by pushing of the key 60 when received in the key slot, such that the padlock 50 can be closed/locked, the padlock 50, in so doing, being displaced upwardly slightly such that the shank 54 abuts the interior face of the upper plate 3B, which provides a reaction force against the shank 54 so that the body 56 can be locked thereto. 10 Exemplary lockable assemblies incorporating the lockbox 1 and padlock 50 will now be described.

In a first example, shown in Figures 4 to 10, the lockbox 1 is incorporated into a hinged door assembly 30 in a shed or steel cabinet. The rear side of the lockbox 1 is welded to an 15 inner surface of a panel of a hinged door 31 in the assembly, as will be apparent from Figure 5, whereby the lockbox 1 is mounted. Referring to Figures 5 and 6, a cutout 34 is formed through the panel immediately below the position where the lockbox 1 is fixed to the panel, whereby a person on the outside of the door 31 can insert digits of his or her hand through the panel to manipulate the padlock 50, as will be described in further detail 20 later. To preclude access to the shed/cabinet interior through the cutout 32, particularly to the screws 4A (which might otherwise then be removable to enable removal of the cover 3D and thus access to the shank 54), a shroud or guard 40 is mounted immediately below the lockbox 1. The guard 40 is formed from steel plate and, referring to Figure 6, comprises upright side walls 40A, an upright front or inner wall 40B, and a flat bottom 25 wall 40C fixed to lower ends of the walls 40A and 40B. The guard 40 defines, below the lockbox 1, a cavity 42 (see Figure 4) which is isolated from the shed/cabinet interior and which provides access to the base 57 of the padlock body 56.

Referring to Figures 5, 7 and 8, mounted to another part of the assembly, with respect to 30 which other part the door 31 swings, is a catch member 60 which engages the assembly formed by the lockbox 1 and padlock 50 mounted therein. In the example shown, the C:\Users\sbt\AppData\Local\Microsoft\Windows\Teniporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 -9- cabinet/shed comprises double-doors, one of which is the door 31, and the catch member 60 is mounted to the other door 32, via a bracket 69 which spaces a fixed end of the catch member 60 inwardly from the door 32. 5 The catch member 60, with reference to Figure 8, is formed from a length of steel rod and bent so as to comprise a first section 61 which extends, away from the fixed end, in a direction parallel to the plane of door 31 (when closed), a second section 62, which projects outwardly from an end of the first section 61, and a third section, which projects downwardly from an outer end of the section 62, the third section 63 defining a catch, 10 referred to previously, which is engageable with the padlock 50, as will be described in further detail shortly.

It will be appreciated that, in another example, the door 31 could be the only door in the cabinet/shed, in which case the catch member would be mounted to a part of the 15 cabinet/shed which is permanently fixed.

With reference to Figures 9 and 10, use of the lockbox 1 to lock the assembly 30 will now be described. With the door 32 retained in a closed condition, e.g. via a padbolt 39 securing it to a frame member of the assembly 30 (see Figure 4), the door 31, with the 20 padlock 50 hung from the retainer 7 in an open condition and the cover plate 3D mounted in position via the screws 4A, is closed, causing the catch 63 to pass through the aperture 5 and thence through the space 52 such that it is received in the cavity 6. The person who has thus closed the door 31 (who is located on the outside thereof) then inserts digits of his or her hand into the cavity 42 (through opening 32) and pushes the base 57 of the padlock 25 body 56 upwardly, thereby closing/locking the padlock 50, whereupon the lower end of the catch 63 is trapped behind the padlock body 56; more particularly, the catch 63 abuts the body 56 if an attempt is made to swing the door 31 open again. The clearances between the interior faces of the sections 3C2, 3D1 and the padlock body 56 are minimal, as are the clearances between the interior faces of the pieces 3C3, 3D2 and the shank 54, the 30 shank 54 and padlock body 56, upon the latter being engaged by the catch 63 if a person tries to pull door 31 open, thus being abutted by the housing 3 so that the padlock 50 C:\Users\sbt\AppData\Local\Microsoft\Windows\TemporaryIntemetFiles\Content.Outlook\P941 ID5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 - 10- cannot be displaced to any significant extent. Moreover, the retainer 7 projects a sufficient distance from the housing rear wall 3C that the shank 54 cannot pass over the free end thereof. More particularly, the retainer 7 is so long that a free end portion thereof is received within the aperture 5 of the cover plate 3D. 5

With the door 31 thus securely locked, the shank 54 is completely shielded, as is the majority of the padlock body 56.

To unlock the door 31, a person inserts the key 60 through the cavity 42 and into the key 10 slot which opens through the base 57, then turns the key 60 whereupon the padlock body is displaced downwardly as the padlock 50 unlocks, such that it no longer obstructs the catch 63, whereby opening of the door 31 is permitted.

An assembly 70 incorporating the lockbox 1 and padlock 50 according to a second 15 example is shown in Figures 11 and 12. This assembly 70, like assembly 30, forms part of a shed or steel cabinet, but comprises a sliding door 71 instead of a hinged door, and a permanently fixed frame structure 72, forming part of the structural frame of the cabinet/shed, which incorporates the lockbox 1. The structure 72 could be modified so as to form a second sliding door which moves, between open an closed conditions, in a 20 direction parallel to door 71, without departure from the invention.

In this example, the lockbox 1 is recessed behind a face of an upright frame member 73, against or adjacent to which face a leading edge of the door 71 is received when the latter is closed, the front of the cover plate 3D being exposed through a cutout 74, provided 25 through the face, such that it faces the door leading edge. The catch member 60 in this example, which is also bent from steel round bar, comprises a straight section 62, which is fixed at one end to the leading edge and extends in the direction from the leading edge to the lockbox 1, and a further section, defining the catch 63, which projects downwardly from the leading end of the straight section 62. 30

The door 71 is provided with rollers 80, at an upper end thereof, via which rollers it hangs C:\Users\sbt\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\P941 lD5X\Speci as filed.DOC-1/03/2017 2017201423 01 Mar 2017 - 11 - from the fixed frame structure of the cabinet/shed. That frame structure is provided with an elongate circular cross-section rail 90 which comprises a length of steel tube section but may alternatively comprise, for example, a length of steel round bar. Each roller 80 is configured with a circumferential channel or groove 81 into which a respective portion of 5 an upper section of the rail 90 is received, whereby the rollers 80 are laterally retained to the rail 90, and thus constrained to movement only in the direction along the rail 90 during opening and shutting of the door 71. The lower end of the fixed frame structure is configured with a channel 95 which provides lateral restraint to the lower end of the door 71, precluding the door from swinging to any appreciable extent about an axis parallel to 10 the rail 90.

The assembly 70, like the assembly 30, incorporates a guard 40 arranged immediately below the lockbox 1. A cutout 34 is formed through an outer wall of the member 73, which cutout provides access to the cavity 42 defined by the guard 40, and thus to the base 15 of the padlock body, allowing the padlock to be closed/locked and opened/unlocked in the manner previously described. In the assembly 70, the opening 32 is perpendicular to the front face of the cover plate 3D, rather than being parallel to it.

When the door 71 is closed, the catch 63 is received through the aperture in the cover plate 20 and thence through the space defined by the shank, so as to be accommodated in the aperture/cavity 6. Closure/locking of the padlock 50 (made possible by the cavity 42) then, in the same manner as previously described, entraps the catch 63 behind the lock body such that the door 71 is locked/closed. Advantageously, because the lockbox 1 is recessed behind the cutout 34, the leading edge of the door 71 can be brought against, or 25 very closely adjacent, to the upright member 73, and fixed in that position when the padlock 50 is closed, precluding access to the cover plate screws, as well as access through the aperture in the cover plate, when the door is locked closed. To preclude any access whatsoever to the section 62 of the catch element 60, a guard 65, comprising a plate section or flange, is attached to or forms part of the member 73, which guard extends the 30 entire height of the gap between the door leading edge and the face and projects away from the member face so as to cover that gap. 2017201423 01 Mar 2017 C:\Users\sbt\AppData\Local\Microsoft\Windows\TemporaryIntemet Files\Content.Outlook\P941 lD5XASpeci as filed.DOC-1/03/2017 - 12-
