Definitions
- the invention relates to an improved barrier section.
- the present invention relates to improved barrier section and connection system between two or more barrier sections.
- the connection system allows the barrier sections to be aligned and retained in at least two different configurations when forming the barrier.
- barriers are used in a number of applications where it is necessary to separate one area from another. Examples of the types of applications barriers may be used include, dividing road lanes, construction sites or other hazardous areas.
- Barriers are typically constructed by connecting a plurality of barrier sections together. Barriers are positioned to fit various configurations and may be connected to that the barrier is made up of various barrier sections. Prior art barrier sections are generally connected together either by a single pin which allows the barrier sections to pivot with respect to each other and not fix in place. Alternatively, the barrier sections are connected by a series of four pins that fix the barrier sections in place and do not allow for any movement or pivoting between the sections.
- one type of barrier connection employs a hinging mechanism, with two parallel sets of projections located on each end of each barrier section.
- the first set of projections on one end forms the gudgeon portion of the hinge mechanism, while the second set of projections on the opposing end forms the pintle portion of the hinge.
- both pintle portions on one barrier section is slotted into both gudgeon portions of another barrier section thereby forming the hinge.
- One disadvantage of this system is the time taken to form this connection increases substantially when further barrier sections have already been connected together, as the user has to ensure that downstream barrier connections do not come apart when the section being worked on is lifted into place. Additionally, as there is no locking or fastening mechanism in this connection, these types of barriers are generally only suitable for flat terrain. Uneven terrain does not allow the projections to properly align and connect together.
- a further disadvantage is that as sections are not locked together, this allows the sections to hinge and easily pivot with respect to each other, therefore offering little structural resistance to an impact force such as from a vehicle impact.
- New Zealand Patent No. 511631 describes another barrier connection system, where a plurality of barrier sections are connected together through a variation on a hinging mechanism.
- each barrier section has a plate that protrudes from the centre of each end on the section.
- Each plate has two projections and when the barrier sections are connected, the two projections overlap the two projections on the other barrier section.
- a single hinge pin is then threaded through an aperture which runs through all four projections to connect the barrier sections together.
- connection device described in this patent also uses hinge elements or brackets to connect a number of barrier sections together. Similar to NZ 511631 , this system has a hinge element located on each end of the barrier section.
- the hinge element is constructed from two brackets that project out and extend the whole width of the end of the barrier section. When in use, the brackets from two barrier sections overlap each other and are attached by a series of pins or bolts. The pins connect the brackets at three different .connection points. One connection point is located in the centre of the bracket, while the other two connection points are at either end of the bracket or side the barrier section.
- NZ 511631 and NZ 524878 One problem with the connections described in NZ 511631 and NZ 524878 is that it is difficult to move a barrier section into a different orientation to the other sections.
- the hinging mechanisms can not be easily re-positioned from the initial arrangement. To re-orientate the barrier sections, the hinges that have to be loosened, the barrier section moved to the desired angle and the hinges tightened. This can be time consuming and labour intensive, as numerous parts have to be manipulated.
- hinging connections are constructed from metal.
- the metal components have to be regularly inspected for wear and tear and to ensure that the systems remain safe and effective.
- the metal needs to be resistant to corrosion and hence tends to add expense to the barrier cost.
- the hinge elements or brackets project out from the end of the barrier section, this may be a potential hazard particularly if the barrier is struck by an impacting vehicle, as substantial damage may be caused to the vehicle and/or passages.
- connection system that would allow at least two barrier sections to run in varying orientations with respect to each barrier section and allow the direction to be easily manipulated. It would also be useful to have a system that has few metal hinging parts or elements that did not have to be routinely checked to ensure safety standards are met. Further, it would be useful to have a barrier connection that would fasten and hold the sections together, therefore allowing the barrier to be constructed and be suitable for a number of different terrains along with provide sufficient support if impacted by a vehicle.
- a barrier section which includes at least one connecting assembly at one or both ends of the barrier section, the connecting assembly having:
- connection section(s) which are positioned to be capable of engaging, or being engaged, with connection section(s) on an adjacent section, in use;
- the barrier section characterized in that the connecting section(s) are configured to engage with the connecting section(s) on an adjacent section via the connecting device so that the barrier sections have either: a fixed, or an at least partially pivotal relationship, with one another.

- the barrier sections may be filled with a fluid, such as water after connection via the connection device of the present invention. Use of water (or other fluids)- in the barrier sections provides greater weight to further support the barrier sections in position.
- the projecting portions(s) and receiving portions(s) may be integral with the body of the barrier section.
- the projecting portion(s) and receiving portion(s) may be made of substantially the same material as the barrier section.
- projection portions(s) and receiving portion(s) may have numerous variations in shape and configuration. In general, the projection portions(s) and receiving portion(s) should complement each other and thereby easily fit together.
- the projection(s) may be at least one protrusion.
- the protrusion may be substantially centrally positioned. In embodiments where there may be three or more protrusions, the protrusions may be evenly spaced with respect to one another.
- the receiving portion(s) may be at least one recess.

- connection device passes through the aligned apertures to engage the barrier sections and connect and retain the barrier sections in place.
- the connecting sections may be configured in a variety of different ways to have either a fixed or pivotal relationship.
- the respective portions may each include two apertures which are spaced apart and positioned to be capable of aligning with the respective aperture on the other portion.
- At least two apertures may pass through the projecting portion(s) and/or the receiving portion(s).
- the apertures may be orientated parallel to each other through the projecting portion(s) and/or receiving portion(s).
- the apertures may run horizontally through the projecting portion(s) and/or receiving portion(s).
- a first or outer aperture may be positioned close to the distal end of the barrier section and a second or inner aperture may run inside the first aperture, closer to the centre of the barrier section.
- the aperture(s) may travel sub vertically from the top of the barrier section to the notch and through to the bottom or bottom region of the barrier section.
- the connecting device may be at least one pin or such like.
- the connecting device may have least two shafts aligned in the same plane, wherein the shafts are adapted to be received through the apertures.
- the connecting device may be at least one U-shaped staple.

- the connecting device may be readjusted to connect the first and second barrier section in a second angled position with respect to each other.
- connecting device to engage the barrier sections is that it is more tolerant of uneven ground or terrain changes than at least some prior art designs. This is because connecting device is: sufficiently robust; and is dimensioned to be suitably sized with the apertures to provide room for non-perfectly aligned apertures as occurs on uneven ground to allow for changes in barrier sections angle.
- connection device allows the connection between two barrier sections to be placed in one position without altering the position of the downstream barrier connections.
- re-positioning a joint between two barrier sections may result in other barrier sections also needing to be re-positioned or even resulting in other barrier sections falling apart and needing to be reassembled.
