Barrier system

Abstract

A mobile barrier system comprises a wheeled trailer and a barrier mounted on the trailer. The barrier comprises a series of panels configured to form walls of the trailer in a collapsed condition for transportation of the barrier. The panels are movable to an erected condition for assembly of the barrier in which the panels are substantially aligned to form the barrier. One or more panels may be adjustable to vary the width of the barrier and two or more barrier systems may be linked to form a wider barrier. Stabilisers are provided to resist movement of the barrier in the erected condition. Guard panels at the top of the barrier can be deployed to resist scaling of the barrier by individuals and/or to increase the height of the barrier.

1 . A barrier system comprising a mobile transportation unit and a barrier for transportation by the unit to a location in which the barrier is to be deployed. 
   
   
       2 . A barrier system according to  claim 1  wherein, the barrier is mounted on the unit and is configured for conversion from an inoperative, collapsed or stowed position for transportation to an operative, erected or deployed position. 
   
   
       3 . A barrier system according to  claim 1  wherein, the transportation unit comprises a wheeled trailer that can be towed by a vehicle to transport the barrier system to the place of use. 
   
   
       4 . A barrier system according to  claim 3  wherein, the barrier comprises a plurality of panels. 
   
   
       5 . A barrier system according to  claim 4  wherein the panels are configured to form one or more walls of the trailer in an inoperative position of the barrier. 
   
   
       6 . A barrier system according to  claim 5  wherein, at least one of the wall panels is connected to the trailer in a fixed position with one or more of the remaining wall panels being hinged to this panel and releasably secured to the trailer so as to be capable of movement to an operative position of the barrier aligned with the fixed wall panel. 
   
   
       7 . A barrier system according to  claim 6  wherein, the fixed wall panel is provided at a rear end of the trailer and has at least one wall panel hinged to each side that extend along opposite sides of the trailer in the inoperative position. 
   
   
       8 . A barrier system according to  claim 7  wherein at least one side wall panel is adjustable to vary the width of the barrier in the operative position. 
   
   
       9 . A barrier system according to  claim 7  wherein, at least some of the wall panels are provided with an additional guard panel at the top of the barrier. 
   
   
       10 . A barrier system according to  claim 9  wherein, one or more guard panels is pivotal between a stowed position for transportation of the barrier and a deployed position in use of the barrier. 
   
   
       11 . A barrier system according to  claim 3  further comprising one or more stabilisers that can be selectively deployed in an operative position of the barrier. 
   
   
       12 . A barrier system according to  claim 11  wherein at least one stabiliser is provided that can be extended from a rear end of the trailer to engage the ground. 
   
   
       13 . A barrier system according to  claim 11  wherein at least one stabiliser is provided that can be lowered from the barrier to engage the ground. 
   
   
       14 . A barrier system according to  claim 11  wherein any or all of the stabilisers is adjustable and lockable in an adjusted position. 
   
   
       15 . A barrier system according to  claim 11  wherein any or all of the stabilisers is provided with a high friction material and/or a large surface area at the point where they contact the ground when deployed. 
   
   
       16 . A barrier comprising at least one barrier system according to  claim 1  configured to form the barrier. 
   
   
       17 . A barrier according to  claim 16  comprising two or more barrier systems linked to form the barrier. 
   
   
       18 . A mobile barrier system comprising a wheeled trailer and a panel assembly mounted on the trailer, the panel assembly comprising a plurality of panels configured to form one or more walls of the trailer in an inoperative position of the barrier system and being transformable to form a barrier in an operative position of the barrier system, at least one of the panels being fixed to the trailer in both the inoperative and operative positions and at least one further panel being hinged to said fixed panel for pivotal movement between a stowed position in the inoperative position of the barrier and a deployed position in the operative position of the barrier 
   
   
       19 . A barrier system according to  claim 18  further comprising stabiliser means on at least one of the trailer and panel assembly for stabilising the barrier in the operative position. 
   
   
       20 . A barrier system according to  claim 18  wherein the panel assembly further comprises anti-scaling means for the barrier in the operative position.
