Definitions

  • the present invention relates to an accessory for a barrier, a barrier, and/or a method of use of the accessory and/or barrier.
  • the barrier can be any type of barrier that prevents, or at least hinders, the movement of one or more persons, animals and/or objects from one side of the barrier to an opposite side of the barrier in use.
  • the barrier could be a security barrier and/or the like.
  • barriers on one or more sides of a road to prevent a vehicle from leaving the road and/ or moving onto an opposite carriageway or other lane defined in the road in use.
  • conventional barriers may not be of sufficient height to prevent a larger vehicle from rolling over the top of the barrier in the event of an impact or accident. It is becoming more prevalent to have larger vehicles travelling on roads and it is therefore becoming increasingly important to have improved safety measures for these larger vehicles.
  • conventional barriers could be replaced with much higher barriers but this replacement would be time consuming to implement, wasteful in respect of the existing barriers, and would incur significant expense.
  • a further problem associated with conventional barriers is that when used on a central reservation of a motorway, the current height of many conventional barriers provides sufficient visibility for a driver travelling on one carriageway to become distracted by one or more incidents that may be occurring on an opposite carriageway, such as for example a crash or an accident. It is known to provide an accessory attached to a top of a conventional barrier in the form of a T-top.
  • a T-top has a base and two opposing upright side walls. The base of the T-top typically protrudes outwardly from the side walls of the barrier and also provides added height to the existing barrier. This helps to prevent a vehicle from "riding up" the barrier in the event of impact of the vehicle with the barrier.
  • the exposed edges of the upright side walls of the T-top can increase the injury risk or risk of "slicing" to a person, such as a motorcyclist, or can increase the damage to a small car, when landing on the same in the event of an accident.
  • an accessory for a barrier including a base member arranged to contact a top or uppermost surface of a barrier in use, two opposing side wall members protruding outwardly from the base member, each side wall member having a first end attached to or integral with the base member and a second end located a spaced distance apart from the base member, and wherein attachment means are provided on or associated with the accessory for allowing attachment of the accessory to a barrier in use, and the second end of each side wall member has a top wall or top portion that protrudes inwardly of the accessory and is opposite to and a spaced distance apart from the base member.
  • the barrier accessory provides a box or box-like member that can be located on top of or on an uppermost surface of a barrier in use to provide a number of additional functions or features to the barrier.
  • the additional functions or features are as follows:
  • the provision of the accessory increases the height of the barrier to prevent or help to prevent:
  • the barrier so as to remove the risk of distraction to a driver or person on one side of the barrier that may be caused by an event, accident and/or the like taking place on an opposite side of the barrier. It can also act as a screen or a base for a screen to prevent dazzle caused by sunlight or from lights of other vehicles on the opposite side of the barrier;
  • the provision of the accessory provides additional strength and rigidity to the barrier when attached to the same in use.
  • top wall or portions of the accessory improves the safety of the accessory compared to other accessory devices which have an exposed upright edge that can cause damage or slicing to vehicles or persons landing on said edge in an accident.
  • the accessory can act as a conduit for the supply and protection of services along the barrier, such as for example, one or more conduits, water pipes, electrical cables, gas pipes, speed detection and prevention means, lighting, traffic counting devices and/ or the like.
  • the accessory can act as a base for the provision of one or more further accessories, panels, fences, screens, information panels, for instructional purposes and/or the like.
  • the accessory is detachably attachable to the barrier in use.
  • the side wall members of the accessory are arranged to protrude upwardly, perpendicular, substantially perpendicular, transverse, vertically or substantially vertically from the base member.
  • the accessory can be attached to any existing or conventional barrier or can be attached to a barrier that is designed specifically for receiving the accessory.
  • the attachment means or the barrier and/or accessory can include any or any combination of one or more apertures, nuts and bolts, straps, screws, clips, joining plates, fasteners, inter- engaging members, anchor pins, mortise andtenon connection, rivets, resin, welding, adhesive and/ or the like.
  • the attachment means includes one or more straps that extend from a surface of the accessory to the barrier and/or along a side wall of the barrier at any point between a base or lowermost surface of the barrier and a top or uppermost surface of the barrier.
  • the attachment means could include one or more anchor pins that engage the one or more straps to a ground surface at or adjacent the base or lowermost surface of the barrier in use.
  • a top surface or uppermost surface of the existing barrier, or a side wall adjacent the top or uppermost surface of the existing barrier is provided with attachment means for allowing attaching of the accessory to the same in use.
  • attachment means are provided on or associated with the base member of the accessory.
  • both the barrier and the accessory are provided with attachment means for allowing attachment of the accessory to the barrier in use.
  • attachment means for allowing attachment of the accessory to the barrier in use.
  • apertures can be defined in a top or uppermost surface of the barrier and in the base member of the accessory for the location of the one or more nuts and bolts therethrough.
  • the apertures on the top or uppermost surface of the barrier and the base member of the accessory are preferably aligned or substantially aligned in use.

  • the top wall or top portion provides an inwardly protruding flange or lip on one or both of the second ends of the opposing side wall members.
  • a space is typically provided between the top wall or top portion of the opposing side wall members.
  • the second ends of the two opposing side wall members can include a combination of one or more top walls or top portions that extend entirely between and are in contact with the two side wall members, and one or more top walls or top portions that extend only partially between the two side wall members.
  • the one or more top wall or top portions of the accessory are integrally formed with one or more of the side wall members and/ or is attached to one or more of the side wall members.
  • one or more apertures, slots, windows, channels and/or the like are defined in the top wall or top portion to allow access to the interior of the accessory in use.

  • the barrier has a longitudinal axis and the accessory is arranged on the barrier such that a longitudinal axis of the accessory is parallel or substantially parallel to the longitudinal axis of the barrier.
  • the barrier includes two or more barriers joined together in an end to end manner. This typically allows an elongate barrier structure to be provided.
  • the accessory is shorter in length than the length of a barrier to which it is to be attached to in use. In one embodiment the accessory can be of such length to be provided over or overlap with two or more barriers in use. In one example the accessory can be of such length to be provided over and/ or overlap with an entire barrier system.
  • a single barrier may have a length of approximately 3 metres and the accessory may have a length of 6 or 12 metres. Thus, the accessory will overlap and be provided over the length of 2 or 4 barrier.
