The present invention relates to an actuating assembly, in particular to an actuating assembly to operate a displaceable component (e.g. a keeper plate) of a latching system between operative and inoperative conditions in response to a signal received via an electromagnetic signal (such as a signal from a telecommunications network).
Disengageable locks are known. For instance, CH446,108 “Tresorschloss” describes a lock wherein a first key actuates a link to engage an unlocking mechanism, and a second key causes the engaged unlocking mechanism to retract a lock bolt to an unlocked condition. Similar disengageable locks are described in DE433,321, DE503,560, DE4,441,834, GB2,206,638 “Electromechanical lock”, GB2,313,148 “Locks”, EP2,562,333 “Automotive and transportation control systems”, WO 99/18311 “Closing device for a lock”, US2014/0197920 “Methods of configuring and using a wireless communications device”, U.S. Pat. No. 3,785,188 “Magnetic controlled door lock”, U.S. Pat. No. 4,580,424 “Single lever, double changeable safe deposit lock”, U.S. Pat. No. 4,656,852 “Lock with a double locking mechanism for a safe, bank compartment or the like”, U.S. Pat. No. 5,219,386 “Locker unit comprising a plurality of lockers” and U.S. Pat. No. 5,701,828 “Electronic security system”.
Furthermore, disengageable locks that engage upon receipt of a remote signal are known. For instance, EP0168884 “Locks” describes a key-releasable lock with a link incorporated in the unlocking mechanism, which link is movable by an electromagnetic actuator in response to a signal received by the lock between: an engaged position, in which the key-releasable lock may be operated; and a disengaged position, in which the lock may not be retracted to an unlocked position. Similar arrangements are described in EP0231532 “A lock having an external bolt unlocking device”, US2009/0049878 “Lock cylinder opening system and method” and U.S. Pat. No. 4,850,623 “Locking mechanisms”.
A drawback of known system is that the disengageable latching system/lock may not be engaged by one of a group of roaming persons (irrespective of the location of such persons) and, after engagement, known disengageable locks do not automatically disengage after expiry of a predetermined time from receipt of a remote signal from a roaming person.
It is an object of the present invention to provide an actuating assembly for a latching system that addresses this drawback.
According to a preferred embodiment of the present invention there is provided an actuating assembly to operate a displaceable component of a latching system, the actuating assembly includes:
In use, the first member may be directly connected or connectable to the displaceable component of the latching system, in which case an output drive member of the actuating assembly is provided by the first member. Instead, the first member may be indirectly connected or connectable to the displaceable component of the latching system, in which case the actuating assembly's output drive member, which may for example be or include a projecting element or arm connected or connectable to the displaceable component of the latching system, may be directly or indirectly connected to the first member, with displacement of the first member causing the output drive member to be displaced.
The latching system is typically for latching a closure member or door to a support structure on which the closure member or door is mounted. The support structure may be a static enclosure or a mobile enclosure. The enclosure may for example be a safe, electrical box, electrical sub-station, truck, delivery van or shipping container.
The first actuating sub-assembly may include a solenoid or an electric motor, e.g. a servomotor, or a linear actuator or an electromagnetic clutch for connecting the first and second members to each other.
In an embodiment of the invention, the first actuating sub-assembly includes a displaceable connecting component and a drive means, e.g. a solenoid, an electric motor or a linear actuator, which includes an output drive member which is connected to the connecting component, the connecting component being displaceable between a connecting position in which it connects the first and second members to each other and a non-connecting position in which it does not connect the first and second members to each other. The first actuating sub-assembly may include a non-mechanical key identification means, with the drive means being linked to the non-mechanical key identification means such that the drive means is operative in response to a signal received from the non-mechanical key identification means to cause displacement of the connecting component from its non-connecting position to its connecting position. The first actuating sub-assembly may be configured such that, after elapse of a preset time measured by the timer, the drive means is operative to cause displacement of the connecting component from its connecting position to its non-connecting position.
The first key, when in the form of an electromagnetic signal, may be encoded, with the key identification means including a decoder to decode the electromagnetic signal.
The actuating assembly may include a first key receiver for receiving the first key, when in the form of an electromagnetic signal.
The actuating assembly may include an electronic controller.
The actuating assembly may include location determining means for determining the location, e.g. the GPS co-ordinates, of the actuating assembly.
The actuating assembly may include storage means for storing an area or location, e.g. the GPS co-ordinates of a location, in which actuation of the first actuating sub-assembly is permitted.
The electronic controller may be configured to permit actuation of the first actuating sub-assembly only when the actuating assembly is at the location or within a specified distance from the location. Thus, for example, for applications where the actuating system is used to operate a component of a latching system for latching a closure member or door to a mobile enclosure, e.g. a motor vehicle, the actuating assembly may include storage means for storing a destination location, e.g. GPS co-ordinates, of the mobile enclosure, with the controller being configured to permit actuation of the first actuating sub-assembly only when the actuating assembly is within a specified distance from the destination location.
The actuating assembly may include a stored location management facility for managing, from a remote location, the area or location stored in the storage means in which actuation of the first actuating sub-assembly is permitted. Thus, with the stored location management facility, the area or location stored in the storage means may be inputted or modified from a remote location.
The actuating assembly may include real time location reporting means for real time reporting, e.g. by emitting a message via an electromagnetic signal to a remote location, on the location of the actuating assembly.
The actuating assembly may further include storage means for storing the co-ordinates of a desired route. The actuating assembly may include route deviation notifying means for notifying, e.g. by emitting a message via an electromagnetic signal to a remote location, when the location of the actuating assembly does not fall along the stored route. The actuating assembly may include a stored route management facility for managing, from a remote location, the route stored in the storage means. Thus, with the stored route management facility, the route stored in the storage means may be inputted or modified from a remote location.
The first actuating sub-assembly may be operably connected to at least one of the first member and the second member. In particular, at least one of the first and second members may include the displaceable connecting component, the connecting component being connected, e.g. pivotally connected, to the remainder of the first or second member, as the case may be, with the connecting component being receivable within a complementary receiving formation defined by the other member, thereby to connect the first and second members to each other. In an embodiment of the invention, the first member includes the connecting component and the second member defines at least one complementary receiving formation for receiving the connecting component, with the first actuating sub-assembly being operably connected to the connecting component so as to cause displacement of the connecting component from its non-connecting position to its connecting position in response to a signal received from the non-mechanical key identification means.
The first and second members may be rotatably displaceable such that, when the first and second members are in their operative configuration, rotary displacement of the second member causes rotary displacement of the first member.
The first member may define a circular aperture. The second member may be located within the aperture of the first member.
In an embodiment of the invention, the first member includes an outwardly projecting arm, with the arm being connected or connectable to the displaceable component of the latching system.
Instead, in another embodiment of the invention, the first member is connected to a linear toothed component, the linear, toothed component in effect providing, or being in the form of, a linear or rack gear, with the linear toothed component being connected or connectable to the displaceable component of the latching system. More particularly, the first member may have a toothed portion which extends at least partially around a periphery of the first member, with the toothed portion of the first member engaging with the toothed portion of the linear or rack gear.
In use, the actuating assembly may be installed on a door frame or surrounds. The displaceable component of the latching system to which the first member is connected may be a displaceable keeper plate which is connected to the door frame or surrounds in a manner such that a degree of displacement of the keeper plate relative to the door frame or surrounds is permitted, the keeper plate defining one or more apertures for receiving one or more latches mounted on the closure member or door. The or each latch may define an upwardly opening groove within which the displaceable keeper plate is captured by abutment of the keeper plate against a wall of the groove when the latch is in a latched position in which it is fast with the door frame or surrounds. Displacement of the first member may operate the latch to unlatch it by causing the displaceable keeper plate to be displaced upwardly so that it is no longer captured within the groove, thus permitting the or each latch to be withdrawn from the aperture of the displaceable keeper plate.
The second key may be a mechanical or non-mechanical key. In a preferred embodiment of the invention, the second actuating sub-assembly includes a mechanical lock mechanism which defines a passage or keyway for receiving a mating mechanical key. The second actuating sub-assembly may be configured to displace the second member when a mating key received in the passage or keyway is rotated. For example, the second actuating sub-assembly may include a drive member which is operably connected to the second member, with the lock mechanism being configured to displace the drive member, with displacement of the drive member causing the second member to be displaced. Instead, the second member may be a drive member of the lock mechanism, the lock mechanism being configured to displace the drive member when a mating key received in the passage or keyway is rotated.
The invention extends to a security system which includes:
The latching system may be as hereinbefore described.
The first and second keys may be as hereinbefore described.
The latching system is typically for latching a closure member or door to a support structure on which the closure member or door is mounted. The support structure may be a static enclosure or a mobile enclosure. The enclosure may for example be a safe, electrical box, electrical sub-station, truck, delivery van or shipping container.
The security system may include storage means for storing an area or location, e.g. the GPS co-ordinates of a location, in which actuation of the first actuating sub-assembly is permitted. The storage means may be proximate to, or part of, the actuating assembly or may be remote from the actuating assembly.
The actuating assembly may include an electronic controller.
The security system may include location determining means for determining the location, e.g. the GPS co-ordinates, of the actuating assembly.
The security system may include storage means for storing an area or location, e.g. the GPS co-ordinates of a location, in which actuation of the first actuating sub-assembly is permitted.
The electronic controller may be configured to permit actuation of the first actuating sub-assembly only when the actuating assembly is at the location or within a specified distance from the location.
The security system may include a stored location management facility for managing, from a remote location, the area or location stored in the storage means in which actuation of the first actuating sub-assembly is permitted. Thus, with the stored location management facility, the area or location stored in the storage means may be inputted or modified from a remote location.
The security system may include real time location reporting means for real time reporting, e.g. by emitting a message via an electromagnetic signal to a remote location, on the location of the actuating assembly.
The security system may further include storage means for storing the co-ordinates of a desired route. The security system may include route deviation notifying means for notifying, e.g. by emitting a message via an electromagnetic signal to a remote location, when the location of the actuating assembly does not fall along the stored route. The security system may include a stored route management facility for managing, from a remote location, the route stored in the storage means. Thus, with the stored route management facility, the route stored in the storage means may be inputted or modified from a remote location.
The actuating assembly may be as hereinbefore described.
The invention will now be described in more detail, by way of examples only, with reference to the accompanying drawings in which:
Referring to
Referring to
The latching system 14 includes a pair of keeper plates 12a, 12b (see
The actuating assembly 10 includes a body or housing 22, a first member 24 and a second member 26 (as best seen in
The first member 24 is annular, the first member 24 defining a central, circular aperture 28. The second member 26, which is also annular, is located within the aperture 28. The second member 26 is co-axial with the first member 24. The first member 24 includes a pivotable connecting component 30. The second member 26 defines on its periphery a plurality of circumferentially spaced receiving formations 32 which are in the form of notches. The connecting component 30 is receivable within the receiving formations 32, the first and second members 24, 26 being connected to each other when the connecting component 30 is received in one of the receiving formations 32, reminiscent of a ratchet comprising a gear and a pawl, but with the pawl not being biased towards the gear.
The first member 24 is also connected to a linear toothed component 34, the linear, toothed component 34 in effect providing, or being in the form of, a linear or rack gear. The first member 24 has a toothed portion 36 (shown in
As best seen in
The actuating assembly 10 also includes a second actuating sub-assembly which includes a mechanical lock mechanism (not shown) and a drive member 56, the lock mechanism being accessible via a keyhole 54 (
As best seen in
The keeper plate 12a defines three vertically spaced, latch-receiving apertures 68a, and the keeper plate 12b defines three vertically spaced, latch-receiving apertures 68b. The door 18 includes three vertically spaced latches 70 (one of which is shown in
In use, when the door 18 is latched to the door surrounds 16, the keeper plate 12a is captured between the walls of the grooves 80 of the latches 70, abutment of the keeper plate 12a against the walls of the grooves 80 inhibiting unlatching and displacement of the door 18, and the first member 24 and second member 26 are in their disconnected, inoperative configuration shown in
In particular, to connect the first member 24 to the second member 26 so that the first and second members 24, 26 assume their operative configuration, the first actuating sub-assembly 46 is activated by means of the electromagnetic signal from a cellular telecommunications network or a remote control device (not shown). The signal is detected by the key identification means (not shown) and, if there is a positive identification by the key identification means that the signal is the correct signal, the solenoid 48 is activated to displace its drive shaft 49 so as to cause the connecting component 30 to pivot towards the second member 26 so that the connecting component 30 is received in the neighbouring receiving formation 32, thereby connecting the first and second members 24, 26 to each other, as shown in
Thereafter, a mating mechanical key (not shown) is inserted via the keyhole 54 into the passage or keyway (not shown) of the lock mechanism (not shown) so that the key engages with elements (not shown) of the lock mechanism such that rotation of the key causes the drive member 56 to rotate in the direction of arrow “A” in
As soon as the mechanical key is released from its unlocking position, biasing means in the form of a spring (not shown), causes the first and second members 24, 26 to disengage from each other. This allows sliding plate 42 to return to its biased locked position under the influence of the biasing means in the form of the aforementioned spring (not shown) and the spring 64. This causes the linear or rack gear 34 and the arm 44 to be automatically lowered.
As the arm 44 of the first member 24 is upwardly displaced, the keeper plate 12a is drawn upwardly with it, against the urging of the coil spring 64. When the first member 24 has reached its uppermost position shown in
When the door 18 is closed, the latches 70 are inserted into the apertures 86, 68a and 68b, the keeper plate 12a being pushed upwardly by the tapered end portions 72 of the latches 70, until the grooves 80 reach the keeper plate 12a, whereafter the coil spring 64 urges the keeper plate 12a downwardly into the grooves 80. In this position, the keeper plate 12a is captured within the grooves 80. For the unlatching of the latches 70, actuation of the actuating assembly 10, as described above, is required.
Referring to
The actuating assembly 100 is similar to the actuating assembly 10 save that, instead of there being a linear or rack gear 34 and a sliding plate 42 with its projecting arm 44, an output drive member of the actuating assembly 100 is a projecting arm 112 of the first member 24. The arm 112 projects outwardly from an annular portion 114 of the first member 24 through a slot 116 defined by the housing 12. When the first member 24 is rotatably displaced, the arm 112 is rotatably displaced along with the remainder of the first member 24. It will be appreciated that the arm 112 provides a rotary output drive member for the actuating assembly 100.
As previously mentioned, the limit switches 88a and 88b detect whether the actuating assembly 100 is in its locked or unlocked condition. The switch 88a is activated by movement of the connecting component 30 and indicates whether or not the connecting component 30 has been displaced by the output drive shaft 49 of the solenoid 48, therefore indicating whether or not the first and second members 24 and 26 are connected. The switch 88b is activated by a pin 118 (shown in
In use, for connecting the first member 24 to the second member 26 so that the first and second members 24, 26 assume their operative configuration shown in
Thereafter, a mating mechanical key (not shown) is inserted in the passage or keyway (not shown) of the lock mechanism (not shown) so that it engages with elements (not shown) of the lock mechanism such that rotation of the key causes the drive member 56 to rotate in the direction of arrow “B” in
When the first member 24 is in its home of locking position, the pin 118 and the switch 88b are aligned with each other and the switch 88b is positively activated. During the unlocking procedure, as the first member 24 rotates away from its locking position, the switch 88b rotates with it, thereby causing the switch 88b to be displaced away from the pin 118 that protrudes from the base of the housing 22, thereby causing the state of the switch 88b to change from a positively activated state to an off or non-activated state.
Referring now to
The security system 200 includes a latching system 210 to latch a door (not shown) mounted on a mobile enclosure (not shown), to surrounds of the door (not shown), an actuating assembly 220 to operate a displaceable component (not shown) of the latching system 210 to latch or unlatch the door, a communications facility 224 which includes a first key emitter for emitting a first key and a second key 226. In this example, the mobile enclosure is a motor vehicle. It will, however, be appreciated the security system 200 could be used with a wide variety of mobile enclosures. Access to a cargo area (not shown) of the motor vehicle (not shown) is controlled by means of the door (not shown) and the security system 200. The first key is in the form of an electromagnetic signal. The second key 226 is a mechanical key.
The actuating assembly 220 is same as the actuating assembly 100 described above, save that it has certain further features as described below. In this embodiment of the invention, the latching system 210 requires a rotary output drive member. It will be appreciated, however, that in an alternative embodiment of the invention (not shown), where the latching system 210 requires a linear output drive member, the actuating assembly may instead for example be the actuating assembly 10.
The first key is for operating the first actuating sub-assembly 46 of the actuating assembly 220. The second key 226 is for operating the second actuating sub-assembly 52 of the actuating assembly 220.
The communications facility 224 sends and receives electromagnetic signals and is part of a monitoring facility or installation 227 which is situated at a location remote from the motor vehicle. The first actuating sub-assembly 46 includes an electronic controller 228 and a communication means 230 for sending and receiving electromagnetic signals to enable communication with the remote installation 227.
The actuating assembly 220 includes a location determining means 234 for determining the location, in particular the GPS co-ordinates, of the actuating assembly 220, and hence of the motor vehicle (not shown) on which it is installed.
The actuating assembly 220 also includes a storage means 236 for storing various items of information as described below.
One of the items stored in the storage means 236 is the location, in particular the GPS co-ordinates, of a planned destination of the motor vehicle. Another item of information stored in the storage means 236 is the distance from the planned destination within which the motor vehicle must be for actuation of the first actuating sub-assembly 46 to be permitted, the permitted distance being 100 metres in one embodiment of the invention. The electronic controller 228 is programmed with software which calculates whether the location of the vehicle as determined by the location determining means 234 is within the permitted distance of the planned destination and, if so, it causes a message to be sent via the communication means 230 to the remote installation 227 that the motor vehicle is within the permitted distance. If the motor vehicle is within the permitted distance, this is indicated on a user interface 238 at the remote installation 227. In this example, the user interface 238 includes a computer monitor whereby the position of the vehicle relative to the planned destination, i.e. whether or not the vehicle with within the permitted distance from the planned destination, and the status of the actuating assembly 220 (e.g. whether the first and second members 24, 26 are in their operative, i.e. connected, configuration and whether or not the first member 24 is in its home or locking position) is displayed. Instead, in an alternative embodiment of the invention (not shown), there could instead be a control panel with differently coloured lights for indicating the position of the vehicle relative to the planned destination and for indicating the status of the actuating assembly 220. The storage means 236 also stores the planned route of the motor vehicle to the destination.
The controller 228 includes a timer (not shown) and is programmed such that, after elapse of a preset time, e.g. elapse of 5 minutes measured by the timer, the solenoid 48 (shown in
The controller 228 is programmed with software to provide a management facility whereby the planned destination and the planned route stored in the storage means 236 can be inputted or modified from the remote installation 227.
The controller 228 is also programmed with software which causes the actual location of the actuating assembly 220 obtained from the location determining means 234 to be continuously reported via the communication means 230 to the remote installation 227. The location determining means 234 and the programmed controller 228 thus provide the actuating assembly 220 with a real time location reporting means for real time reporting on the location of the motor vehicle (not shown).
The controller 228 is also programmed with software which compares the actual location of the motor vehicle with the planned route, the actual location being obtained from the location determining means 234. If there is a discrepancy between the actual location and the planned route, the programmed controller 238 causes a notification to be sent via the communicating means 230 to the remote location 232 that the actual route of the motor vehicle (not shown) does not conform with the planned route. The locating determining means 234 and the programmed controller 228 thus provide a route deviation notifying means for notifying the remote installation 227 when the actual route of the motor vehicle (not shown) does not conform with the planned route.
As described above with reference to the actuating assembly 100, the actuating assembly 220 includes limit switches 89a, 89b, the switch 89a for detecting displacement of member 30 and thus the engagement between first and second members 24 and 26. The actuating assembly 220 also includes sensing means (not shown) to detect whether the actuating assembly 220 has been struck by lightning and whether the locking mechanism of the second actuating sub-assembly 52 has been tampered with, e.g. if the second member 26 has been rotated without the first member 24 having been rotated indicating that an attempt had been made to unlock the locking mechanism when the first and second members 24, 26 were in their inoperative configuration. The switches 89a, 89b and the sensing means are connected to the controller 228.
The controller 228, by means of input from the switches 89a, 89b, can detect whether or not the actuating assembly 220 is in a locked condition, i.e. the condition in which the first and second members 24, 26 are in their inoperative configuration and the first member 24 is in its home or locking position. The controller 228 can then cause a message to be sent to the remote installation 227 indicating the condition of the actuating assembly 220 in this regard so that the display panel of the user interface 238 can display whether the actuating assembly 220 is in a locked or unlocked condition. If the sensing means (not shown) detects that the actuating assembly 220 has been struck by lightning or that the locking mechanism of the second actuating sub-assembly 52 has been tampered with, the controller 228 causes a message to be sent to the remote installation 227 which results in a warning message being displayed on the display panel of the user interface 238.
In use, prior to the departure of the motor vehicle to deliver cargo to a planned destination, the planned destination and the planned route are inputted via the user interface 238 at the remote installation 227 into the storage means 236 of the first actuating sub-assembly 46. The door to the cargo area of the vehicle is latched to its surrounds by means of the latching system 210. Once the door is latched, it cannot be unlatched without actuation of the actuating system 220.
Once the motor vehicle has arrived at its destination, the driver telephones the remote installation 227 to request actuation of the first actuating sub-assembly 46. If the motor vehicle is within the permitted distance from the planned destination, this is indicated on the display panel of the user interface 238 at the remote installation 227. If the display panel indicates that the vehicle is within the permitted distance from the planned destination, an operator at the remote installation 227 causes a first electronic key for the first actuating sub-assembly 47 to be sent via the communication facility 224 to the actuating assembly 220 for actuation of the first actuating sub-assembly 46, i.e. the solenoid 48 (shown in
Once the first and second members 24, 26 are in their operative configuration, the driver can unlatch the latching system 210 by insertion of a mating mechanical key 226 into the passage of the locking mechanism of the second actuating sub-assembly 52 and rotationally displacing the key 226. As described above with reference to the actuating assembly 100, the rotational displacement of the key 226 causes the drive member 56 of the locking mechanism to rotate, which in turn causes the second member 26 and the first member 24 also to rotate, with the arm 112 rotating with the remainder of the first member 24 and causing the latching system 210 to unlatch.
As described above, the switch 89b can detect whether or not the first member 24 has been displaced from its home or locking position. If the actuating assembly 220 is not unlocked, i.e. if the first member 24 is not displaced away from its home or locking position, within five minutes of the receipt by the first actuating sub-assembly 46 as measured by the timer (not shown), the solenoid 48 causes displacement of the connecting component 30 from its connecting position to its non-connecting position. As previously mentioned, it is possible to achieve the uncoupling either: (i) by the controller 228 sending a signal for the solenoid to push (i.e. reverse direction) thereby disengaging element 30, 26; or (ii) by the controller 228 stopping the electromagnetic signal to the solenoid and by the biasing influence exerted by springs (not shown) displacing element 30 back into its natural inoperative configuration. In other words, elapse of a preset time measured by the timer from receipt of a first key by the first actuating sub-assembly causes the first and second members to assume their inoperative configuration. Unlocking of the actuating assembly 220 is then no longer possible until the first key is again sent from the remote installation 227 to the actuating assembly 220.
As mentioned above, whilst the motor vehicle is travelling, the real time location reporting means continuously reports on the location of the motor vehicle to the remote installation 227. If the motor vehicle deviates from the planned route, the route deviation notifying means notifies the remote installation 227 of the deviation.
By means of the invention as illustrated and described, an actuating assembly 10, 100 is provided which requires actuation by two keys (not shown) in order to displace its output drive member 44, 112. This can provide enhanced security when, in use, the actuating assembly 10, 100 is connected to a latching system. The actuating assembly 10, 100 can furthermore bear a significant amount of torque and load when compared to, for example, conventional actuating assemblies that are only electronically activated; however, the inclusion of the first actuating sub-assembly 46 in the actuating assembly 10, 100 described above means that tampering with the lock mechanism resulting in rotary displacement of the second member 26 should not in itself cause unlatching since, without the first and second members 24, 26 being connected to each other, displacement of the second member 26 will not cause the first member 24 to be displaced, and thus the output drive member 44, 112 will not be displaced.
Further, the security system 200 as illustrated and described can provide enhanced security which can be of particular use for cargo-carrying motor vehicles. In particular, before the locking mechanism can be unlocked with the key 226, the actuating assembly 220 must receive a first electronic key from the remote installation 227. Beneficially, the condition of the actuating assembly 220 and the location of the motor vehicle can be monitored from the remote installation 227. In particular, an operator at the remote installation 227 can check whether the motor vehicle is within the permitted distance of an intended destination before sending the first key. This provides an additional safety measure which can help to prevent loss of cargo due to robbery or theft along the route since the operator can ensure that the motor vehicle is at the planned destination before sending the first key.
It will be appreciated that, since the first key is a predetermined electromagnetic signal transmitted by a cellular telecommunication network (i.e. may be triggered by a cellular telephone), the person that provides the first key may roam. Furthermore, by automatically causing the first and second members to assume their inoperative condition after lapse of a predetermined time from receipt of the first key by the first actuating sub-assembly, the actuating assembly is rendered more secure against tampering and unauthorised operation.
