Description

Mounting module for secure rooms

Technical field.

This invention concerns secure rooms. More particularly, it concerns a module for inclusion in the doorway of type 1 (top secret) secure rooms, on which door monitoring, door control and surveillance apparatus may be mounted. However, the invention may be used in any room which is not a type 1 secure room but in which a degree of security and/or control is required.

Preliminary note.

In this specification, including the claims, "directional" terms (such as "top", "bottom", "side", "underside", "upper, "lower", "above", "upwards", "below", "inwards", "behind", "horizontal", "vertical" and the like) wifi be used in the sense that these terms would have with reference to an embodiment of the invention positioned as shown in Figures 2 to 9 of the accompanying drawings.

Background to the invention.

Doors of a type 1 security room usually have a number of security features associated with them. In particular, each door of a type 1 secure room, and each of the two doors of a type 1 secure room having an entry through a double door or through a "door and a half" door, is required to have the following equipment operatively associated with it a) a magna lock assembly which holds the door (or the two doors) securely closed until the magna lock is de-activated to permit the door (or doors) to be opened; b) a pair of magnetically biased, balanced reed switches, which provide a visual signal indicating whether the door is (or the doors are) open or closed; c) a "door open too long" signal generator (usually called a DOTL signal generator); d) a door closer, or two door closers if the entry to the room is through double doors or a "door and a half" door; and e) a camera (to monitor the interior of the room).

When entry to a type 1 secure room is through double doors or "door and a half" doors, a door sequencer (described in more detail below) is also required. A door sequencer ensures that when the doors are being closed, one of the two doors (namely the door which has its vertical edge which is remote from its mounting hinges either bull-nose shaped or arcuately curved), will close before the other door (the other door having a vertically extending right-angled strip on its vertical edge which is remote from its hinges, to provide a vertical, elongate flange which covers the gap between the two doors when they are closed).

These are official requirements. All of these listed components are known. In practice, however, seldom is all the required security, control or monitoring equipment mounted in an appropriate location relative to the door. And when most of the required equipment is present, only rarely does the door, after the equipment has been installed, comply completely with the fire regulations.

Disclosure of the invention.

It is an object of the present invention to provide a mounting module which can be positioned in the doorway to a secure room and onto which the control, security and monitoring equipment required for type 1 secure rooms can be mounted.

This objective is achieved with a mounting module comprising a rectangular metal strucwre which is dimensioned to fit within the top region of the frame of the door.

This mounting module has (1) a planar top plate which fits under the head of the door frame; (2) a pair of planar side plates, each of which extends vertically downwards from a respective end of the top plate; and (3) a planar bottom plate which extends horizontally between the lower edges of the side plates (and which is, therefore, parallel to the planar top plate).

The rigidity of this mounting module is enhanced by a vertical bracing flange (or a number of bracing flanges) extending inwardly from at least part of the edges of the top plate, the bottom plate and the side plates on the "room side" of the mounting module (the other side being termed the "door side" of the module).

If the module is to be used with a room having a single door, the mounting module will have a first mounting member in the form of a generally rectangular plate having dimensions such that a door closer may be mounted on it. This plate extends vertically downwards from the door-side edge of the top plate, with one side edge of this plate closely adjacent to one of the side plates. Normally, this first mounting member will be attached to (usually welded to, when the mounting module is constructed using steel plates) both the edge of the top plate and the edge of the adjacent side plate. The bracing flange on the room side of the mounting module will normally be cut away (or at least reduced in size) in the region of the first mounting member, to provide for access to the door closer from inside the room.

For a type 1 secure room with a double door, or with a "door and a half" door (which henceforth in this specification, including the claims, will be included in the term "double door"), the mounting module will have a pair of first mounting members, each in the form of a generally rectangular plate having dimensions such that a door closer may be mounted on it. Each such plate extends vertically downwards from the door-side edge of the top plate, and has one side edge that is closely adjacent to a respective one of the side plates of the mounting module.

Normally, each first mounting member wifi be attached to (usually welded to,when the mounting module is constructed using steel plates) both the edge of the top plate and the edge of its adjacent side plate. Preferably, the bracing flange on the room side of the mounting module is cut away (or at least reduced in size) in each region of the first mounting member, to provide for access to the door closers from inside the room.

For each type of security door, the mounting module has a second mounting member, typically in the form of a rectangular plate, extending vertically downwards from the room side edge of the top plate of the mounting module. This second mounting member has dimensions which enable the electromagnetic unit component of a magna lock magnetic door holding apparatus to be mounted on it.

If the room has double doors, a single second mounting member will normally be used to support two magna lock units. Conveniently, the second mounting member may comprise, or be formed integrally with, a portion of the bracing flange of the mounting module. The second mounting member is, of course, spaced apart from the first mounting member, for the door closer and the magna lock operate on different regions of the top of a door.

A third mounting member, in the form of a plate which extends vertically upwards from the door side edge of the bottom plate of the mounting module, has dimensions which enable a pair of magnetically biased, balanced reed switches to be mounted on it.

A fourth mounting member, in the form of a small plate on the room side of the mounting module, mounted on a supporting member that extends downwardly from the top plate of the mounting module, is adapted to have a DOTL (door open oo long alarm unit) mounted on it.

A fifth mounting member, in the form of a bracket on the bottom plate of the mounting module, having a vertically extending mounting plate, has dimensions that enable a surveillance camera to be mounted on it. Preferably, there will be no bracing flange (or there will be a cut out region of the bracing flange) on the room side of the mounting module alongside the region where the surveillance camera is to be mounted.

If the door with which the mounting module is to be used is a double door, provision for mounting a door sequencer (described later in this specification) will also be included in the mounting module. A portion of the bottom plate, below the third mounting member, will normally be used for this purpose.

Thus, the present invention provides a mounting module for use with the door (which may be a double door) of a type 1 secure room; said mounting module having a "door side" and a "room side"; said mounting module being mountable in the head of a door frame with said "room side" facing into said room; said mounting module comprising: a) a rigid structure having (1) an elongate, rectangular, planar top plate, having a length essentially equal to the length of the head of the frame of said door; the plane of said top plate being substantially horizontal when the mounting module is installed for use; (2) a pair of rectangular, planar side plates, each extending substantially vertically downwards from a respective end edge of said top plate, (3) a rectangular, planar bottom plate, located between, and attached to, said side plates at the lower edges of said side plates, the plane of said bottom plate being substantially parallel to the plane of said top plate, and (4) at least one planar bracing flange extending vertically into the space between the edges of said top, bottom and side plates on the room side of the mounting module; b) a first mounting member (or a pair of spaced apart first mounting members in the case of a mounting module for double doors), the (or each) first mounting member comprising a generally rectangular plate having dimensions such that a door closer may be mounted on it, said (or each) generally rectangular plate extending vertically downwards from the door-side edge of said top plate, one side edge of said generally rectangular plate being closely adjacent to an edge of one (or a respective one) of said side plates, said (or each) first mounting member being attached to both the edge of said top plate and the edge of said (or its associated) adjacent side plate; c) a second mounting member in the form of a rectangular plate, extending vertically downwards from the room side edge of said top plate; said second mounting member having dimensions which enable an electromagnetic unit component of a magna lock magnetic door holding apparatus to be mounted thereon (in the case of a mounting module to be used with double doors, said second mounting member being dimensioned to have two inagna lock electromagnetic units mounted thereon); said second mounting member being spaced apart from said first mounting member; d) a third mounting member, in the form of a plate which extends vertically upwards from the door side edge of said bottom plate, said third mounting member having dimensions which enable a pair of magnetically biased, balanced reed switches to be mounted on it; e) a fourth mounting member, in the form of a small plate on the room side of the mounting module, mounted on a supporting member that extends downwardly from the top plate of the mounting module, said fourth mounting member being adapted to have a DOTL unit mounted on it; and f) a fifth mounting member; said fifth mounting member comprising a bracket on said bottom plate; said bracket having a vertically extending mounting plate with dimensions that enable a surveillance camera to be mounted on it; said bracing flange being absent or reduced in size alongside the region where said surveillance camera is to be mounted.

As noted above, if the door with which the mounting module is to be used is a double door, provision for mounting a door sequencer will also be included in the mounting module.

Preferably, the mounting module will be provided with enclosed channels through which cables (for example, cables supplying power to the monitoring and surveillance equipment installed on the mounting module, and cables along which information signals from the monitoring and surveillance equipment are passed) may be routed. Such channels minimise the opportunity to tamper with those cables, or accidentally cause damage to those cables when installing the monitoring and surveillance equipment in the mounting module.

Embodiments which include features of the present invention will now be described, by way of example only. In the following description, reference will be made to the accompanying drawings.

Detailed description of the illustrated embodiments.

Figure 1 is a schematic view of one end of a type 1 secure room that has been fitted with the present invention. This room has double doors 11 and 14. The required monitoring, control and surveillance equipment for this room has been mounted in a mounting module 10 which has been constructed in accordance with the present invention. The set ceiling 12 of the room is fitted with a security hatch 13, which provides access, when required, to the space above the ceiling.

The present inventor has constructed prototypes of the mounting module 10. The prototypes of the mounting module are depicted in Figures 2 to 9.

Each of the mounting modules shown in Figures 2 to 9 has a top plate 20, a pair of side plates 21, 22, and a bottom plate 23. A flange member 24, connected to the room side edges of the plates 20, 21, 22 and 23, provides bracing and creates a rigid rectangular structure for the mounting module. For a type 1 secure room, this rectangular structure (including the bracing flange 24) is preferably made by welding together lengths of heavy gauge steel plate. If the mounting module is to be used in connection with rooms which have a lesser security designation (for example, a lecture hail, a function room of an hotel, a dangerous chemicals store, an armoury, a library, a bond store -this list is not exhaustive), this rectangular structure may be constructed using any other suitable material (including certain rigid plastics materials). A series of individual flanges could be used in place of the flange member 24. However, those individual flanges would have to be designed and located to ensure that the rectangular assembly of top plate, bottom plate and side plates is properly braced by the individual flanges.

A first mounting member 25, on which a door closer, not shown in the drawings, will be mounted, is attached to the rectangular structure of the mounting module shown in Figures 2 to 5. Two first mounting members 25 (on each of which a door closer will be mounted) are attached to the rectangular structure of the mounting module for double doors, which is illustrated in Figures 6 to 9.

In each case, the first mounting member 25 is a generally rectangular plate, having its planar surfaces vertical, that is welded (in the prototype mounting modules) to the door-side edge of the top plate 20 and to the door side edge of the side plate 22 (the adjacent side plate 22 or 23 in the case of the double doors module). The arm of the door closer that is mounted on a first mounting member 25 will be attached to the top region of the associated door, and will pass underneath the first mounting member 25. Note that, in these embodiments, the bracing flange 24 has a cut away portion or a reduced size portion 26 to provide access to the door closer from the room side of the mounting module.

A second mounting member 30, formed integrally with the bracing flange 24 in the illustrated embodiments, is located in the upper region of the mounting module.

The electromagnetic unit of a magna lock assembly is mounted behind, but on, the second mounting member (that is, the magna lock unit is mounted underneath the top plate 20, but on the second mounting member). Two such electromagnetic units will be mounted behind the second mounting member 25 of the mounting module for double doors, illustrated in Figures 6 to 9. A magna lock plate is mounted on the (or each) door of the secure room in a position such that, when the door is closed, the magna lock plate is adjacent to (and under the influence of) the associated electromagnetic unit of the magna lock assembly, being separated from that unit by only the thickness of the second mounting member 30. When the magna lock unit is actuated, a very large pulling force is required to open the associated door.

A third mounting member 32, consisting of a vertical plate onto which a pair of double balanced reed switches with adjustable magnetic bias may be mounted, is provided on each rectangular structure immediately above the door side edge of the bottom plate 23. The reed switches are mounted on the back of the vertical plate 32 (that is, above the bottom plate 23). At least one side bracket member 33 extends between a respective side edge of the vertical plate 32 and the bracing flange 24 of the prototype mounting modules. A channel member 34 of rectangular cross-section, mounted within the rectangular structure formed by the plates 20, 21, 22 and 23, and the bracing flange 24, is used to locate cables which are connected to the reed switches.

A fourth mounting member 37, mounted on a support member, is provided to support a DOTL (an indicator that shows when the door has been open too long).

The fourth mounting member 37 comprises a vertical plate on the room side of the mounting module. In the mounting module for a single door, the support for the plate 37 is a second channel member 38, and the plate 37 is located in the upper region of the module, but below the portion of the bracing flange 24 which extends downwardly from the top plate 20. In the prototype mounting module for double doors, the channel member 34 has been used as the support member for the plate 37, and the plate 37 is located in the lower region of the module, above that part of the bracing flange 24 which extends upwardly from the bottom plate 23. The channel members 38 and 34, which each have a hollow rectangular cross-section, house the cables to and from the associated DOTL indicator. In the mounting module for a single door, the channel 38 also houses cables to and from a surveillance camera ii that may be mounted on a fifth mounting member 40.

The fifth mounting member 40 shown in Figures 2 to 9 comprises a simple right-angled bracket, welded to the top surface of the bottom plate 23. The vertical portion of the bracket 40 is spaced a distance from the room side of the mounting module which allows a surveillance camera to be located between the bracket 40 and the bracing flange 24. In the mounting module for double doors, a second channel member 38 houses cables to and from the surveillance camera when it has been mounted on the fifth mounting member 40. Note that a second cut out portion of the bracing flange 24 is provided to allow the surveillance camera mounted on the bracket 40 to have an uninterrupted view of the room.

As noted above, an additional component is required when entry to the secure room is through double doors, namely, a door sequencer. A door sequencer may be mounted on the mounting module shown in Figures 6 to 9, below the vertical plate 32. As shown in Figure 10, when the double doors 11 and 14 are opened, a spring biased arm 17 of a door sequencer, which has a small wheel 18 at its free end, moves out from the position in which it has been held by the closed door 14. The door 14 has a right-angled strip 15 affixed to the vertical edge of the door 14 which is remote from its door hinges. The door sequencer arm 17 soon reaches its maximum extension position, which is adjustable. It remains in that extended position until the doors are closed by the door closers mounted on the first mounting member 25. If the door 14 with its right-angled strip 15 closes before the door 11, the wheel 18 bears against the door 14 and prevents its further closure. The vertical edge 16, which is remote from the binges of the door 11, has a bull-nosed or arcuate shape. When this edge 16 of the door 11 comes into contact with the arm 17, it pushes the arm 17 in the direction of the arrow A. As the door 11 continues to close, it continues to move the arm 17 (with the wheel 18 rotating), until the wheel 18 reaches a position on the surface of the door 14 such that the door 14, biased closed by its door closer, pushes the wheel -and therefore the arm 17 -further towards the position it occupies when the door 14 is fully closed. With this arrangement, the door 11 must close first.

When both doors are closed, the vertical "tongue" 15A of the strip 15 will overlap the edge 16 of the door Ii. The tongue 15A of the strip 15, therefore, prevents a person outside the secure room from observing part of the interior of the room through the space between the vertical door edges when the doors 11 and 14 are closed.

A cover will normally be screwed onto the room side of the mounting module, after the various monitoring, control and surveillance components have been fitted onto their respective mounting members of the mounting module. This cover prevents casual access to those components.

Advantages of the present invention when it is used with the door or doors of a type 1 secure room (a room in which work requiring absolute security may be undertaken) include: -the tamper-proof (or tamper-evident) nature of the mounting module when the required componefits are mounted on it; -the ability of a security organisation to purchase a mounting module which can be supplied with various monitoring, control and surveillance components mounted on the module, or readily mountable on the module, so that installation times will be kept to a minimum; -the ability to have additional savings with production runs producing a significant number of mounting modules; -the fact that there is space in the mounting module to include additional components, if required, in the future; and -the module enables a neat installation to be achieved with all the required monitoring, control and surveillance components present in a manner that does not affect the ability of the room to meet the requirements of fire regulations.

This list of advantages is not exhaustive.

As noted earlier in this specification, although the mounting module of this invention has been designed to meet the requirements of a type 1 secure room, the module can be used for rooms with various security classifications, which may require the use of only some of the various monitoring, control and surveillance components that have to be mounted on a module for a type 1 secure room. Such an arrangement permits the room with a lesser security classification to be "upgraded" to a higher security classification in the future by the simple act of mounting the additional required equipment on the mounting module.

It will be apparent to engineers in this field that variations to and modifications of the illustrated mounting modules described above may be made without departing from the present inventive concept, as set out in the following claims.
