DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to security barriers for vehicles particularly for use in car parks to prevent theft and unauthorized access.
BACKGROUND TO THE INVENTION
Most car parks if they provide any barrier to entry or exit provide a boom gate at the entry and exit points to the car park. This offers some security but is not sufficient to deter car theft in many instances. Individual restraints For car parking spaces have been used where a steel tube barrier is folded down to allow the vehicle to be parked and is lockable in an upright position when the car is parked or the space is being reserved. These restraints are manually operated and fixed in their position.
Remotely actuated vehicle barriers have been proposed for roadways and parking spaces but, as exemplified by GB patent 2282838 and German patent 4307045, these only move the barrier from one fixed non barrier position to a second fixed barrier position.
Although car parking spaces are generally of uniform dimensions, cars are not. Usually there is no restraint on any side of a car space or in some cases at the end of the space. Costs dictate that an ideal barrier system will provide a barrier at the two longitudinal ends of the space which is what most proposals have done. However these restraints are not sufficient to prevent cars of short body length from being maneuvered past the barrier. The only suggestion made to address this problem has been to PROVIDE side restraints to individual car spaces, which is expensive as well as inhibiting driver and passenger access to the vehicle.
It is an object of this invention to provide a cost effective secure car parking space which overcomes the above problems.
SUMMARY OF THE INVENTION
The present invention provides a secure car space which has an end for entry and exit from the space, a fixed barrier at the end opposite the entry, and which further includes at the entry end an adjustable barrier moveable from a non barrier position to a position in which it prevents egress of a parked vehicle characterized in that the barrier is able to be positioned the same distance from a vehicle regardless of the vehicle's length.
This invention is predicated on the realization that the car parking space need not be "one size fits all". By having a barrier which adjusts to the size of the vehicle the possibility that a small car can be maneuvered out of the car space is avoided.
In another aspect this invention also provides an adjustable barrier system including to an erect position and to move the erect vehicle barrier into close proximity to said vehicle to prevent its egress from the parking space.
For convenience the barrier is located at ground level when the car space is available. A central location adjacent the entry end of the car parking space is most effective. The controller or actuation means is most effectively located on a post at a central position at the other end of the car space, especially where there is no other barrier at that end.
The barrier can be any shape, but is most conveniently a post mounted on a conveyor in a track in the floor of the car space. The conveyor mechanism both raises the barrier into an erect barrier position and moves it to a location adjacent one end of the vehicle to prevent its being driven away. The post includes a sensor which senses the location of the vehicle and cooperates with the actuation means to provide a signal to stop the movement of the post at a predetermined distance from the parked vehicle.
The length of the conveyor and its location in the car space is determined by the length of the space and the length of the shortest and longest vehicles to be accommodated. The non barrier position is conveniently at the entry end of the parking space so that less movement of the post is required with longer vehicles and all movement of the erect post is toward the end of the parked vehicle.
The actuation means to be secure needs to be key, card or code activated. A mechanism which releases a key, or ticket to be used to initiate the r
