Definitions

• the present invention relates to a barrier portion for use in a barrier system, and a barrier system.
• Barriers are often erected in a temporary capacity as and when required. For example, temporary barriers are often employed for safety purposes to prevent members of the public from entering a potentially unsafe area whilst building work is being undertaken. The barrier may then be removed once the building work has been completed.
• temporary barriers do not always provide adequate performance in such circumstances.
• temporary barriers often require a compromise between a number of performance metrics including length, stability, portability, ease of storage and ease of shaping the temporary barrier around hazards or an area to be demarcated.
• some temporary barriers are provided with the individual barrier panels permanently connected to one another. Such temporary barriers may enable adequate stability of the barrier, but typically do not enable portability, ease of storage or ease of shaping of the barrier as desired. In addition, such temporary barriers generally have a fixed barrier length that cannot be extended or reduced as desired. Conversely, some temporary barriers are provided with the individual barrier panels separate or releasably connected to one another. Such temporary barriers often provide portability and ease of shaping of the barrier. However, such temporary barriers often do not provide adequate stability or ease of storage, and can be slow to deploy as each barrier panel must be handled separately. The present invention has been devised with the foregoing in mind.

• the barrier portion may comprise an A-frame structure.
• the barrier portion may be configured to cooperate with one or more barrier panels to form a barrier when the said barrier system is in a deployed configuration.
• the A-frame structure may be configured to stabilise the said barrier.
• a barrier portion comprising an A-frame structure may provide improved stability to a said barrier comprising the barrier portion and one or more barrier panels.
• An A-frame structure comprises an inherently stable triangular shape.
• An A-frame structure may also be simple to manufacture and implement.
• An A-frame structure may also effectively utilise the dimensions of the barrier portion to provide stability to the barrier without significantly increasing barrier weight or impacting on usable barrier length.
• the A-frame structure may be movable between a closed position and an open position. That may enable the barrier portion to be compact when the barrier system is in a stored configuration whilst providing stability when the barrier system is in the deployed configuration.
• the A-frame structure may comprise two components - optionally two halves - movably connected to each other.
• the two components may be rotatably e.g. hingedly or pivotably connected to each other at or towards an end thereof to permit movement between the closed position and the open position.

• the at least one half of the A-frame structure may also comprise one or more side portions extending substantially perpendicularly from opposing edges of the primary portion.

• the barrier portion 105 comprises an A-frame structure.
• the A-frame structure is movable between a closed position and an open position.
• Figures 2A and 2B show the A-frame structure in the closed position, whilst Figure 2C shows the A-frame structure in the open position.
• the A-frame structure may not be movable between a closed position and an open position, but may be permanently fixed or held in an open position.

• the first half 105 A and the second half 105B of the A-frame structure are configured to move between the closed position and the open position by pivoting about the hinge point 105C. In the closed position shown in Figures 2A and 2B, the two halves 105 A, 105B of the A-frame structure of the barrier portion 105 are substantially parallel to and adjacent one another.
• the two halves 105 A, 105B may be in contact with one another in the closed position.
• the two halves 105 A, 105B of the A-frame structure are angled relative to one another such that at a second end 107 of the A-frame structure opposite the hinge point 105C, the two halves 105 A, 105B are separated from one another to form a structure shaped substantially similar to a capital letter A (commonly referred to as an A-frame structure).
• the A-frame structure of the barrier portion 105 stabilises the barrier by providing a wider support base for the barrier system 100 than a substantially planar barrier panel (for example, a barrier panel 102). That wider support base provided by the A-frame structure of the barrier portion 105 may reduce a risk of the barrier tilting, tipping over or falling down when deployed.

• first half 105 A and the second half 105B may be separated by or angled relative to one another at an angle of between substantially 1° and substantially 45° in the open position.
• a longitudinal or vertical position of the strap on the A-frame structure may determine a length of the strap required to prevent excessive opening of the A-frame structure in the open position.
• a strap located at a higher position on the A-frame structure would not require as great a length as a strap located at a lower position on the A-frame structure.
• other suitable restraint mechanisms may be used, such as a tongue or flange on the first half 105 A receivable in corresponding groove on the second half 105B (or vice versa), the groove comprising a stop to prevent further travel of the tongue or flange.
• the barrier portion 105 may not comprise a restraint mechanism 108.

• the male portion 109A aligns with the female portion 109B. Elastic energy stored in the male portion 109A due to the male portion 109A deflecting around the first half 105 A is released, enabling the male portion 109A to be forced towards and received by the female portion 109B, thereby securing the A-frame structure in the closed position.
• the securing mechanism 109 is therefore configured to automatically engage when the A-frame structure is moved to the closed position.
• the securing mechanism 109 may not automatically engage when the A-frame structure is moved to the closed position, but may require manual input to secure the A-frame structure in the closed position.
