The security enclosure may comprise a securing apparatus to secure the access member in a closed position. The securing apparatus may comprise a securing member movable from a non-securing position to a securing position and actuating means for moving the securing member. Actuation of the actuating means may move the securing member to the securing position.

The actuating means may comprise a switch which may be operable between on and off positions by a manipulating member. The manipulating member may comprise a key.

The switch may be provided on a key receiving element. The switch may be movable between the on and off positions by the manipulating member.

The actuating means may comprise a displacement device for displacing the securing member between the securing and non-securing positions. Actuation of the actuating means may cause the displacement device to displace the securing member to the securing position.

The displacement device may be electrically connected to the switch. Movement of the switch to the on position may cause electricity to be supplied to the displacement device, which may displace the securing member. The supply of electricity to the displacement device may displace the securing member to the securing position.

The displacement means may comprise urging means to urge the securing member to the non-securing position. The displacement device may comprise a solenoid.

The switch may be mounted on a closure, such as a door of a storage region. The closure may comprise a lock for locking the closure in a closed position. The key receiving element may be provided on the closure and may be associated with the lock for locking and unlocking the closure.

The lock may be movable between a locked condition in which the closure is locked and unlocked condition in which the closure can be opened. The key receiving element and the switch may be arranged such that, when the key is inserted into the key receiving element and turned to move the lock to the unlocked condition, the switch actuates the displacement device and displaces the securing member to the securing position.

The lock may be operable on the supply of electric power thereto. The closure may comprise power shut off means to shut off the electric power to the lock. The power shut off means may shut off the electric power to the lock when the closure is opened.

The power shut off means may comprise a switch which is opened on opening of the closure. The provision of the power shut off means provides the advantage, for one embodiment, of preventing the lock being moved to the locked condition when the closure is open, thereby maintaining the securing member in the securing position.

The securing apparatus may include a release switch to allow the access member to be opened. The release switch may control the displacement device to allow the securing member to be retracted. In one embodiment, operation of the release switch may switch off the supply of electrical power to the displacement device, thereby retracting the securing member.

The release switch may comprise a further key receiving member for receiving a further key, and which may be capable of being operated by the further key, to cut off the supply of electric power to the displacement device, thereby allowing the securing member to be retracted.

In one embodiment, the security enclosure may hold telecommunications apparatus.

The telecommunications apparatus may be provided in one of the first and second wall arrangements of the security enclosure. An aperture or recess may be defined in one of the first wall members for receiving the telecommunications apparatus.

A recess may be defined in the corresponding second wall member to allow the second wall member to receive the telecommunications apparatus when the second wall member is in its retracted condition, and to allow the second wall memberto move between its retracted and extended conditions.

A cover member may be provided to cover the recess when the second wall member is in the extended condition.

The cover member may be movable between closed and open positions, and may be movable between an open position when the second wall member is in the retracted condition and a closed position across the recess when the second wall member is in the extended condition. The cover member may be a plate, such as a steel plate.

Urging means, such as a spring arrangement, may be provided to urge the cover member to the closed position.

An embodiment of the invention will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view from above of a security enclosure with an extension compartment in a retracted condition; Figure 2 is a perspective view from above of the security enclosure shown in Figure 1 with the extension compartment in an extended condition; Figure 3A is a side view of the security enclosure shown in Figure 2 in the extended condition; Figure 3B is a side view similar to Figure 3B of a modified security enclosure; Figure 4 is a perspective view from above of a carrying assembly used with the security enclosure shown in Figures 1 to 3; Figure 5 is a perspective view from below of the carrying assembly shown in Figure 4; Figure 6 is a top plan view of the carrying assembly shown in Figures 4 and 5 with a roof element removed; Figure 7 is a front perspective view of the security enclosure, with the outer wall member and the front wall removed; Figure 8 is a circuit diagram of a locking device for use with the security enclosure shown in figures 1 to 3; Figure 9 is a perspective view from above of another embodiment of a security enclosure with an extension compartment in a retracted condition; Figure 10 is a perspective view from above of the security enclosure shown in Figure 9 with the extension compartment in an extended condition; and Figure 11 is a view of a drive mechanism used in the embodiment shown in Figures 9and 10.

Referring to figures 1 to 3, there is shown a security enclosure in the form of a security booth 10. The security booth 10 is used to house an automated teller machine 11 for dispensing cash. Such automated teller machines are known in the

art and are not described in this specification.

The security booth 10 comprises a main body 12 having first and second side wall arrangements 14, 16, a fixed roof 18, a front wall 20, and a rear wall 22.

Each of the first and second side wall arrangements 14, 16 comprises respectively a first wall member in the form of a fixed inner wall member 14A, 16A and a movable second wall member in the form of a movable outer wall member 14B, 16B. The movable outer wall members 146, 166 are movable between a retracted condition shown in Figure 1 and an extended condition shown in Figures 2 and 3.

The front wall 20 extends across the front of the outer wall members 14B, 16B, and an inner roof 24 extends across the top of the outer wall members 14B, 16B. Thus, the two movable outer wall members 14B, 16B, the front wall 20, and the inner roof 24 together provide a movable extension compartment 26 which can be slid from the retracted condition shown in Figure 1 to the extended condition shown in Figures 2 and 3, and from the extended condition to the retracted condition.

The extension compartment 26 is mounted on a carriage assembly 40 (see Figures 4 to 6). The carriage assembly 40 is movable between a retracted condition, in which the extension compartment 26 is retracted to its position around the main body 12, and an extended condition, in which the extension compartment 26 is in its extended condition in front of the main body.

The movement of the extension compartment 26 is guided by runners 27 extending along a lower region of the inner wall members 14A, 16A. The runners 27 co-operate with rollers 27A shown in broken lines in Figure 3.

In the embodiment described herein, the runners 27 provide minimal support for the extension compartment 26, serving mainly to guide the extension compartment 26.

Instead, the majority of the weight of the extension compartment 26 is supported by the carriage assembly 40.

The carriage assembly 40 comprises a fixed support assembly 42 fixedly mounted on the main body 12. Figures 4 and 5 show the fixed support assembly 42, which comprises a pair of opposed rail members 44 having inwardly facing bearing engagement faces 46.

A bracing member 48 extends between the rear ends 50 of the two rail members 44.

The carriage assembly 40 further includes a carriage assembly 52, which comprises first and second carriages 54, 56. The first carriage 54 comprises opposite rail elements 58, each having an outwardly facing bearing engagement face 60.

The inner roof 24 is mounted on the first carriage 54. The outer wall members 14B, 16B are mounted on the inner roof 24, and extend downwardly therefrom, as shown in broken lines in Figure 4.

A rear bracing member 59 extends between the rear ends 61 of the rail elements 58, and a front bracing member 63 extends between the front ends 65 of the rail elements 58.

The second carriage 56 comprises a pair of bearing carrier members 62 on each of which two outwardly facing bearings 64 are provided to co-operate with the inwardly facing bearing engagement faces 46 of the rail members 44. The outwardly facing

II

bearings 64, in co-operation with the inwardly facing bearing engagement faces 46, facilitate linear motion of the second carriage 52 relative to the fixed support assembly 42, as shown by the double headed arrow A. The second carriage 56 also comprises a bracing member 66 extending between the rear ends 68 of the bearing carrier members 62.

The second carriage 56 is movable between two positions, namely (a) an extended position in which the bracing member 66 is substantially midway along the rail members 44 of the fixed support assembly 42, as shown in Figures 4 to 6, and (b) a retracted position in which the bracing member 66 of the second carriage 56 is adjacent the bracing member 48 of the fixed support assembly 42, as shown in broken lines in Figure 6. A suitable stop arrangement is provided to prevent movement of the second carriage 56 beyond the extended position shown in Figure 6.

Two inwardly facing bearings 70 are provided on each of the bearing carrier members 62 and co-operate with the outwardly facing bearing engagement faces 60 of the rail elements 58 of the first carriage 54. The inwardly facing bearings 70, in cooperation with the outwardly facing bearing engagement faces 60, facilitate linear motion of the first carriage relative to the second carriage, as shown by the double headed arrow B. The first carriage 54 is movable between two positions, namely (a) an extended position, as shown in Figure 6, in which the rear bracing member 59 is substantially midway along the bearing carrier members 62, and (b) a retracted position in which the rear bracing member 59 of the first carriage 54 is adjacent the bracing member 66 of the second carriage 56, as shown in broken lines in Figure 6. A suitable stop arrangement is provided to prevent movement of the first carriage 54 beyond its extended position shown in Figure 6.

The provision of a carriage assembly 40, having three stages, namely a fixed support assembly 42 and first and second carriages 54, 56, in this embodiment, provides the advantage that the first carriage 54 can extend substantially wholly beyond the fixed support assembly 42, and yet is held firmly in position by the second carriage 56. Thus, the extension compartment 26 extends substantially wholly beyond the main body 12, and yet can be fully retracted to its position around the main body 12.

The extension compartment 26 may define an enclosed region 28 within the extension compartment 26. When the extension compartment 26 is in the extended condition, the enclosed region 28 is provided forward of the main body 12.

An access member in the form of an outer door 30 is provided in the front wall 20. A rectangular access aperture 32 is defined in the outer door 30 to allow access to the automated teller machine 11 when the extension compartment 26 is in the retracted condition shown in Figure 1.

If desired, the security enclosure 10 could be used to hold a public telephone. In such an embodiment, as shown in the drawings, particularly Figure 3, in which a telephone 33 is mounted in a rectangular aperture 35 in the inner wall member 16A.

Where a telephone 33 is provided in the inner wall member 16A, the outer wall member 16B defines a rectangular recess 37 to allow access to the telephone 33 through the outer wall member 16B when the outer wall member 16B is in the retracted position. When the outer wall member 16B is in the extended position, as shown in Figure 3A, a metal plate 39 is arranged over the aperture 37 to prevent access to the extension compartment 26. The rectangular recess 37 is generally the same size and shape as the rectangular aperture 35. The metal plate 39 is removed when the extension, 26 is moved back to its retracted position.

If desired, a fuse box 41 can be provided within the aperture 35 in the inner wall member 16A and, as can be seen from Figure 3 the rectangular recess 37 in the outer wall 1 6B is large enough to extend around the fuse box 41. An access door 43 in the inner wall member 16A is provided over the contents of the fuse box 41 to prevent unauthorised access.

In a modification shown in Figure 3B, the aperture 35 in the inner wall member 16A extends only around the telephone 33, and does not extend around the fuse box 41.

Similarly, the rectangular recess 37 in the outer wall member 16B, as shown in Figure 3B does not extend around the fuse box 41. Instead, an access door 43B is provided in the outer wall member 1 6B to allow access to the fuse box 41.

When the extension compartment 26 is in the extended condition shown in Figure 2, access can be gained to the enclosed region 28 forward of the main body 12 via the outer door 30. Such access is required by engineers wishing to carry out maintenance on the automated teller machine 11, or by security personnel wishing to replenish the cash in the automated teller machine 11. In the latter case, it is particularly desirable for the security personnel to be enclosed within the enclosed region 28 to prevent access by thieves and robbers.

When the engineer or the security personnel is within the enclosed region 28, a closure plate 34 can be arranged to cover the aperture 32 from the inside, and secured in position. Only part of the cover plate 34 is shown in Figure 2.

Securing apparatus may be provided within the security booth 10 to secure the outer door 30 in its closed condition, when cash is being replenished in the automated teller machine 11.

The front wall 20 has a front mounting plate 72 fixedly mounted above the outer door 30. The front mounting plate 72 has mounted therein a securing member, in the form of a bolt 74 (see Figure 7). The bolt 74 is driven by suitable displacement means, which in the embodiment shown is a solenoid 76.

The bolt 74 is movable between extended and retracted positions. The supply of electric power to the solenoid 76 moves the bolt to its extended position. A resilient urging means in the form of a spring moves the bolt to its retracted position when the supply of electric power is switched off.

When the bolt 74 is in its extended condition it extends through the bottom of the mounting plate 72 into an aperture in the upper edge of the outer door 30, thereby securing the door 30 in its closed condition.

The solenoid 76 can be any suitable solenoid known in the art, but at a suitable such a solenoid is sold by Emessem solenoid Company Ltd, and is sold under the name of D. C. Right-angle Lock Unit, Type 60.

Figure 8 shows an electrical circuit 77 connecting the solenoid 76 to a cabinet door lock 78 on the cabinet door 80 of a cabinet 82. The cabinet 82 is shown in Figure 7.

When the cabinet door lock 78 on the cabinet door 80 is in its locked position, as shown in solid lines in Figure 7, then electricity is not supplied to the solenoid 76 and therefore the bolt 74 is maintained in its retracted condition.

When the cabinet door lock 78 is moved to its unlocked position, electricity is supplied to the solenoid 76 and the bolt 74 is moved to its extended position, thereby extending into the outer door 30, locking it closed.

Referring to Figure 8, the circuit 77 comprises a supply 79 of electric power. The circuit 77 also comprises a cabinet door lock switch 84 operated by the cabinet door lock 78, and a relay 85 connected between the cabinet door lock 78 and the solenoid 76. When the cabinet door lock 78 is in its locked position, the cabinet door lock switch 84 is open thereby preventing the flow of electricity to the solenoid 76.

Conversely, when the cabinet door lock 78 is in its unlocked position, to allow the cabinet door 80 to be opened, the cabinet door lock switch 84 is closed thereby closing the relay 85 and allowing a flow of electricity to the solenoid 76. This moves the bolt 74 to its extended position, locking the outer door 30 closed.

The cabinet door lock 78 is operable only with a supply of electricity thereto. If electricity is not supplied to the cabinet door lock 78, it will not operate.

The circuit 77 further comprises an outer door position switch 86 mounted on the outer door 30. The purpose of the outer door position switch 86 is to shut off the supply of electricity to the cabinet door lock 78 when the outer door 30 is open.

The outer door position switch 86 is in its open position, as shown, when the outer door 30 is open and, as a result, electricity is not supplied to the cabinet door lock 78, and it cannot be unlocked. Also, when the outer door position switch 86 is open, no electricity is supplied to the solenoid 76. Thus, the bolt 74 remains retracted within the solenoid 76.

Electricity is only supplied to the cabinet door lock 78 when the outer door 30 and, consequently, the outer door position switch 86 are closed. This is a safety feature of this embodiment, and means that the cabinet 80 cannot be opened until the outer door 30 is closed.

The circuit 77 also includes a cabinet door position switch 88 mounted on the cabinet door 80. The cabinet door 80 is movable between an open position and a closed position.

In the open position of the cabinet door 80, the cabinet door position switch 88 is also open, thereby switching off the supply of electricity to the cabinet door lock 78 and preventing the cabinet door lock 78 being operated. In the closed position of the cabinet door 80, the cabinet door position switch 88 is also closed, thereby providing a supply of electricity to the cabinet door lock 78, allowing it to be locked and unlocked.

The circuit 77 is provided with an emergency switch 90 in the form of a key receiving element on the outside of the main body 12. When the appropriate key is inserted into the key emergency switch 90, and turned to an off position, the supply of electricity to the solenoid 76 is cut off. This immediately results in the bolt 74 being retracted to its position within the solenoid 76, and the outer door 30 can then be opened.

There is thus described an advantageous embodiment, in which the provision of outer sliding walls 14B, 16B allows easy maintenance on themain body 12, in addition to providing a secure enclosure for an engineer or security personnel to work on the automated teller machine 11 inside.

Various modifications can be made without departing from the scope of the invention. For example, the security enclosure 10 could be devoid of a telephone, and the inner and outer wall members 16A, 16B would be the same is the inner and outer wall members 14A, 14B.

Referring to Figures 9 to 11, there is shown a further embodiment of the invention.

The security enclosure shown in Figures 9 to 11 is generally designated 110, and comprises many of the same features as the embodiment shown in Figures 1 to 8.

These features have been designated with the same reference numerals as in Figures 1 to 8.

One of the differences between the embodiment shown in Figures 9 to 11 and the embodiment shown in Figures 1 to 8 is that the embodiment shown in Figures 9 to 11 is larger and includes a roof 118 having a curved front projecting portion 118A. A further difference lies in the provision of a drive assembly 120 (see Figure 11) to drive the extension compartment 26 between the retracted position shown in Figure 9 and the extended position shown in Figure 10.

The drive assembly 120 comprises a rotary drive motor 122 fixedly mounted on the front bracing member 63. A transmission member comprising a threaded elongate element in the form of a screw jack 124 is mounted on the rotary drive motor 122 for rotation thereby. The screw jack 124 is threadably received in an internally threaded nut element 126, which is fixedly mounted to an inner roof member 128 of the main body 12, by a mounting bracket 130.

A guide sleeve 132 extends from the mounting bracket 130 to the rear wall arrangement 22. The guide sleeve 132 is provided to receive the screw jack 124 when the carriage assembly 40 is in its retracted position.

The operation of the drive assembly on and on 20 will be described with reference to Figure 11. In Figure 11, the carriage assembly 40 is in the extended position, and when it is desired to move it to the retracted position, the drive motor 122 operates to rotate the screw jack 124 about its longitudinal axis. The outer thread on the screw jack 124 co-operatively engages the inner thread on the nut 126. Thus, by rotating the screw jack 124 in one direction, the screw jack 124 is screwed into the nut 126 and is received within the guide sleeve 130. This moves the carriage assembly 40 to its retracted position.

When it is desired to move the carriage assembly 40 to its extended position, the drive motor is actuated to rotate me screw jack 124 in the opposite direction thereby unscrew in the screw jack from the nut 126 and moving the screw jack 124 out of the guide sleeve 132 A further difference between the embodiment shown in Figures 9 to 11 and the embodiment shown in Figures 1 to 8 is, in the embodiment shown in Figures 9 to 11, that the roof 118 is fixedly mounted to the first carriage 54. This means that the inner roof 128 is fixed in place as part of the main body 12.
