Description
Barrier Svstem lthe present invention relates to a barrier system for use
in restricting access to a particular locality via a point of access to that locality.
Although the following description refers almost exclusively to a barrier system in the form of one or more retractable bollards for use in the prevention of stealing cars, it will be appreciated by persons skilled in the art that the barrier system of the present invention could include any type <-if gate, pivotal bollards and/-'r the like which restricts access to any person, animal, vehicle and/or article to a locality when the barrier means are provided in a closed condition.
(I at crime is on the increase and it is becoming increasingly more common for cars to be stolen from a user's premises as a result of the premises being burgled and the car keys being stolen. Barrier systems are provided on access points of premises in an attempt to prevent unauthorised persons from entering the premises but there is currently no security system specifically designed to prevent cars being stolen or removed from a premises. For example, barrier systems in the form of one or more bollards which can be lifted into and out of the ground lay a user are known. Whilst such a system is likely to reduce the risk of a car being stolen from the premises, a ear . thief could still remove the bollards if they get hold of keys used -.
. for locking the bollards in place. Furthermore, it is time consuming for the user to have to remove and replace the bollards each time they wish to enter or leave the premises. .
Another example of a barrier system is in the form of electronic gates at an entrance to premises. 'Lyle electronic gates can be opened by a user in a vehicle via operation of a remote control device and/or a user may be required to operate some kind of telecom system located at the gateway which allows someone on the premises to operate a switch to open the gates if the user is authorised to enter the premises. problem with this type of barrier system is that it often requires electrical cables to be provided between the gate and a control panel in the premises, thereby making the system costly and causing significant clisrupton when being tatted. I7urthermore, these gates typically prevent all access to the premises by persons or animals, such as friends, the postman, the milkman and/or the like, unless they are provided with a remote control device.
Barrier systems are known which use automated movable bollards to overcome the abovementioned problem by allowing selective access to premises whilst preventing entry or exit of larger objects to or from the premises, such as a car. The bollards can be moved between open and closed positions by entry of a code into a fixed input device adjacent the bollards but this typically requires the user to get out or stretch out of their vehicle to input the code. This is inconvenient for the user, particularly if the weather is cold or wet. further method of actuating movement of the bollards is by using a remote control device. However, when a vehicle is located in front of or behind the bollards, the driver of the vehicle is typically unable to see when the bollards are fully retracted car raised. As such, the driver of the vehicle Is often required to exit the vehicle to . determine the position of the bollards before they can determine see.
I' whether it is safe tc> drive over the bollards. If the bollards are not fully retracted when the user drives over the bollards, they are likely to cause damage to the front or underside of their vehicle. :
It is known to provide signalling systems in the form of audible alarms, traffic lights or flashing lights on or adjacent the barrier means to indicate to a user when it is safe to pass through or over the barrier means. I lowever, such signalling systems are usually large, unsightly and/or noisy and arc therefore not suited for use in rcsidcutial areas or small premises.
It Is therefore an object of the present patent application to provide a barrier system which overcomes the abovementioned problems and which provides a safe and effective means of restricting access to a particular premises or locality.
According to a htst aspect of the present invention there is provided a barrier system for restricting access to a particular locality via a point of access to said particular locality, said barrier system including barrier means movable between a first open position, wherein access to said particular locality is substantially unrestricted via said access point, and a second closed position, wherein access to said particular locality is restricted via said access point, said system including user actuation means for causing movement of said barrier means between said open and closed positions and characterised in that said user actuation means is provided with signalling means for signalling the status of the barrier means to a user.
Preferably the user actuation means and the barrier means arc in wireless communication with each other. ...
. Thus, the user actuation means and the barrier means are -.
. typically independently arranged, separate units, thereby alkwng the user actuation means to be operated in a vehicle, # for example, without the user having to refer to any external or A-.
separate display or signal other than in the vehicle or on the user actuation means. 'this allows a user to determine the status A. : of the barrier means without leaving their vehicle and without ë requiring signalling means to be audible or visible to other people within the vicinity.
Preferably the barrier means and the user actuation means are provided with transmitters, receivers and/or transceivers for allowing said wireless communication between the same for operation calf the barrier system. Thus, the user actuation means can operate the barrier means remotely and the barrier means can signal the status of the barrier means to said user actuation means remotely.
l he wireless communication can be any or any combination of radio waves, infra red waves, microwaves and/or the like. Once the user actuation means and the barrier means are within a pre- determined distance of each other, data communication therebetween can occur.
(once the status of the barrier means has been signalled to the user actuation means, processing means in said actuation means processes the signal and generates a status signal via said signalling means.
In one embodiment the status of the barrier means is indicated/signalled following actuation of one or more buttons or switches on the user actuation means. Alternatively, the status of the barrier means can be signalled to the user actuation . means whenever the user actuation means is within a pre see.
i determined range of the barrier means. -.
In one embodiment the user actuation means are provided with user input means for Inputting security data therein. For example, the security data can include any or any combination of a pin code, identification code, user details and/or the like. The user actuation means typically does not allow actuation of the barrier means without firstly inputting correct or recognisable security data therein. This user input means can include one or more buttons, rotatable dials, voice recognition and/or the like.
Preferably micro-processing means provided in the user actuation means allows processing of the input security data and comparison of said security data with data stored in memory therein or connected thereto. If correct or recognisable security data is input, the actuation means allows activation of the barrier means and/or the status of the barrier means is signalled to said actuation means.
In one embodiment the user actuation means is in the form of a key fish or key ring.
in a further embodiment the user actuation means is integrally formed with or detachably attached in a vehicle associated with said locality.
The sgnalling means can include visual, audio and/or kinaesthetic signalling means.
In one embodiment the visual signalling means can include a display screen on which cane or more messages, images or text is provided for informing the user of the status of the user actuation means and/or barrier means. Alternatively, or in addition, one or more lights, coloured lights, LEDs and/or the . like can be lit, flash and/or switch off depending on the status of the barrier means. Thus, the user can see the status of the A... .
barrier means and determine when it is safe to pass over or e through the barrier means by looking at means provided on their person -' r in a vehicle. .
In a further embodiment the audio signalling means includes one or more spoken messages, alarms and/or the like.
In a yet further embodiment the kinaesthetic signalling means includes vibration means and/or the like.
The barrier means can include any or any combination of one or more retractable bollards, pivotable bollards, gates or fencing, barrier arm and/or the like.
Preferably the barrier means provides selective, restrictive or prevents access to the locality in said closed position, and open, increased or full access to the locality in said open position.
In a preferred embodiment the barrier means are in the form of one ->r more retractable bollards. The bollards are typically provided in a housing located in a ground or floor surface. The top of the housing can be recessed or substantially flush with the floor or ground surface in use to prevent a user tripping up over the same ' r prevent the same from damaging a vehicle or object passing over the same.
l'referably a transmitter, receiver and/or transceiver are provided on an exterior surface, on top of, inside and/or adjacent a bollard, such as in the housing. A further transmitter, receiver and/or transceiver can be provided on the user actuation means. ease
A
Whilst the barrier means and user actuation means are described herein as including transceivers, it will be appreciated by persons skilled in the art that communication can be one way, using a transmitter and receiver or two way using transceivers.
. . 'I;wo-way communication has the advantage that it reduces the likelihood of "grabbing" (i.e. unauthorised recording of codes from the user actuation means) taking place since the system of the present invention in this embodiment requires identification data to be sent from the user actuation means to the barrier means and from the barrier means to the user actuation means bcf-'rc the barrier system becomes operational.
According to a second aspect of the prescut invention there is provideLI a barrier system for restricting access to a particular locality via a point of access to said particular locality, said barrier system including one or more retractable bollards movable between a first open position, wherein the bollards are substantially recessed in the ground and access to the particular locality is substantially unrestricted via said access point, and a second closed position, wherein the bollards arc raised and access to said particular locality is substantially restricted via said access point, said system including user actuation means for causing movement of said bollards between said open and closed positions, characterized in that said user actuation means is in wireless communication with said barrier means and the signallng means provided in, on or associated with said user actuation means is capable of signalling the status of the bollards to a user.
Ehc user actuation means is typically portablc/mobile/transportablc and can be carried by a user as and when required. fiche user therefore does not have to exit a vehicle or building in order to actuate the user actuation means I' and/or to view a status signal. ce
lhc user actuation means typically includes a housing on which user input means and signalling means arc provided. : ..
In addition to the portable user actuation means, further signalling and/or control means can be provided in the locality or premises to allow one or more users in the premises to determine the status of the barrier means. For example, a low voltage cable could be provided in the locality between the barrier means and a required location in the locality, such as a house.
According to a further aspect of the present invention there is provided a meth<:>d of using a barrier system according to the present invention.
Acccr<1ing to a yet further aspect of the present invention there is provided user actuation means for use with a barrier system; and barrier means for user with a barrier system.
An advantage of the prescut invention is that even if car keys for a vehicle are stolen, the burglar or thief cannot remove the vehicle from the premises without first knowing the security data for operation of the barrier system. In addition, the barrier system of the present invention prevents unauthorised access of a vehicle or barrier means via a child. Thus, the present invention provides security between the barrier means and a user to prevent damage of a vehicle or article with respect to the barrier means. In addition, the present invention can also provide security between the barrier means and the user actuation means by requiring two-way communication using .- identification data therebetween. .e
Len embodiment of the present invention will now be described with rcfercncc to the accompanying figures, wherein: .

. display screen 18 on front face 16 of the housing. A first set of . ..: buttons 20, 22, 24 is provided for allowing control of the bollards 2 and for switching the key fob 12 between on/off conditions. More specifically, button 20 allows movement of the bollards from a retracted position to a raised position, button 22 allows movement of the bollards from a raised position to a retracted position and button 24 switches the key fob between on and off conditions.
User input means in the form of a set of numbered buttons 26 are also provided on front face 16 to allow a security code to be input into the key fob. The security code must be input into the key fate before the same will function. A microprocessor and memory are provided in the key fob to allow the input security code to be compared to stored security data. If the input data is correct, the key fob can then be operated to display the status of the bollards ancl/or allow movement of the bollarcls. If the input data is incorrect, the key fob will remain inoperable.
A transceiver 28 is provided on housing 14 which communicates via radio waves with transceivers 30 provided in a recess on the top surface 32 of each bollard 2. Thus, the bollard transceivers are located such that they can easily receive signal data sent from the key fob 12 whilst preventing damage to the same as a result of the transceivers protruding from the bollard or being accessible therefrom.
The key fob 12 is typically battery powered and the housing 14 .. is provided with a compartment therein for location of one or .
more batteries. The transceiver on each bollard can also be battery powered or operated from a mains power supply. .
It Is t' be noted that the barrier system can be provided in a master/slave arrangement, with a single transceiver car . communication crevice provided on one of the bollards .
. lo: (designatecl as being the master barrier means) and one or more further communication devices provided on the other bollards to allow communication therebetween and/or with the mater barrier means. The master and slave barrier means can operate substantially simultaneous with each other and/or the master barrier means could operate at different times to one or more of the slave barrier means.
Following actuation of button 20, 22 for allowing movement of the bollards, a message is displayed on displayed screen 18 to allow the user to determine the status of the bollards. Thus, for example, a message can be displayed saying "safe to pass" when the bollards are fully retracted or "do not pass" when the bollards are raised. A user can see this message and then decide when it is safe for them to drive over the bollards.
Other signalling means can be provided on the key fob. For example, a green light can be lit when the bollards are fully retracted and a red light can be lit when the bollards are raised.
The user actuation means could be fitted into the user's vehicle so that the user does not have to remember to carry the key fob on their person.
Other information or functions can be linked to the user actuation means if required. For example, the user actuation means can display data relating to the status of an immobiliser .. in a vehicle and/or the like. In addition, the user actuation .- means could communicate with other devices operating using .
radio waves, such as a mobile telephone, a lap top computer, :. television screen and/or the like. ë e. -
The barrier means can communicate the status of the same to : . the user actuation means directly or indirectly via another unit .
or control device. The barrier means may also communicate directly with the signalling means associated with the user actuation means or indirectly via some other device.
Thus, the present invention provides a mobile device for allowing a user to remotely control and determine the status of barrier means. Area .a. .. .e
