[0046] FIG. 18 is a perspective view illustrating a temporary barrier in accordance with another embodiment of the invention.

[0047] Referring to FIGS. 1 to 6, a temporary barrier 10 is illustrated, the barrier 10 being intended for use in applications in which it is required to restrict pedestrian access to certain areas. By way of example, it may be used in crowd management or control applications, to restrict pedestrian access to areas in which access is restricted for safety reasons, for example because works are being undertaken in those regions, or in a range of other applications. The barrier 10 comprises a barrier panel 12 supported upon a pair of feet 14. The expressions “upper” and “lower” are understood with reference to the panel in its intended in-use configuration, standing on its feet 14, corresponding to the reading orientation of FIG. 1.

[0048] The panel 12 is of multi-part form, comprising a first panel component 16 and a second panel component 18 arranged in a side-by-side configuration and secured to one another using an upper elongate reinforcing member 20. Optionally, the first and second panel components may be further secured to one another using, as shown herein, a lower elongate reinforcing member 22. The panel components 16, 18 are of moulded plastics material form manufactured by, for example, injection moulding. It will be appreciated that, as the panel 12 is of multi-part form, and in particular as it is made up of first and second panel components 16, 18, the components of the panel 12 are each of sufficiently small dimensions that they can readily be manufactured using injection moulding or compression moulding techniques, for example.

[0049] The panel components 16, 18 are substantially identical to one another, and so only one of them will be described herein in further detail with reference to FIGS. 7 to 10.

[0050] As shown in FIGS. 7 to 10, the panel component 16 comprises an upper rail 24, a lower rail 26 and an end post 28. A series of uprights 30 extends between the upper and lower rails 24, 26, the uprights 30 extending substantially parallel to the end post 28.

[0051] The upper and lower rails 24, 26 are of substantially square cross-section, hollow form, as shown in FIG. 9 (showing a section of the upper rail 24), and are formed with a series of windows 32 spaced apart along the length of the respect rail 24, 26. The windows 32 are formed so that some of them open to one face of the component 16, and others of them open to the other face of the component 16. The windows 32 are arranged in an alternating fashion. The rails 24, 26 are thus of a shut through form, lending themselves to manufacture using plastics material moulding techniques in a relatively simple and convenient manner. FIG. 9 also illustrates in section the upper elongate reinforcing member 20 extending through the hollow upper rail 24, one side (the left-hand side in the reading orientation of FIG. 9) of the hollow upper rail 24 showing in section a window 32 through which the elongate reinforcing member 20 is visible.

[0052] The end post 28 is of H-shaped cross-sectional form, as shown in FIG. 8. Most of the uprights 30 are similarly of H-shaped cross-sectional form, but are of smaller dimensions than the end posts 28 (see also FIG. 15 described below). H-shaped cross sections are suited for injection moulding. The H-shaped cross section is symmetric and therefore provides the same appearance at either side of the panel when assembled. Other cross-sections may be used.

[0053] As illustrated in FIG. 10, the upright 30 aligned with the associated foot 14 is of a different design to the remainder of the uprights 30 in that it is of hollow tubular form formed with windows 34 arranged in an alternating fashion similar to the windows 30.

[0054] The reinforcing members 20, 22 are of hollow, substantially square cross-sectional shape, of dimensions allowing them to be fitted within the hollow rails 24, 26. Conveniently, they are of pultruded or extruded form, preferably of a fibre reinforced plastics material. The material is conveniently brightly coloured. It will be appreciated that with the reinforcing members 20, 22 positioned within the hollow rails 24, 26, parts of the reinforcing members 20, 22 will be exposed, to be visible through the windows 32, as illustrated in FIG. 6. FIG. 6 corresponds to FIG. 1 and shows the upper and lower elongate reinforcing members 20, 22 and upright reinforcing members 36, 38 (for more detail on the reinforcing members, see additional description with reference to FIGS. 7 to 10) with cross-hatching; the cross-hatching is intended to illustrate their visibility through alternating windows 20 in the barrier panel components, but it will be understood that the reinforcing members may not necessarily exhibit a visible cross-hatching pattern, and may be of a single colour. One or more of the reinforcing members may be of a contrasting colour relative to the colour of the barrier panel component to provide improved visibility. For instance, the reinforcing members may be of a bright colour, and/or have light-reflecting properties. To provide illustrative examples, the barrier panel components may be of any suitable colour such as orange, dark grey or black, or any colour desired by a customer, and the reinforcing members may be of bright yellow or white reflective colour. By being recessed within the rails, the reinforcing members are somewhat better protected than paint, coating or stickers applied directly to the surface of the barrier panel, while still providing good visibility.

[0055] As shown in FIGS. 1 to 6, the reinforcing members 20, 22 are of a relatively great length, extending over at least half of the width of the panel 12, and preferably extending over significantly more of the width than this. Each of the reinforcing members 20, 22 is thus located partly within the respective rail of the first panel component 16, and partly within the respective rail of the second panel component 18. By way of example, the reinforcing members 20, 22 may extend over three quarters, or more, of the width of the panel 12. The reinforcing members 20, 22 are secured within the rails 24, 26 using any suitable technique. By way of example, screws or nuts and bolts or other threaded fasteners may be used, extending through appropriately positioned openings formed therein. Alternatively, rivets could be used, or suitable adhesives may be used. It will be appreciated that these techniques represent examples of suitable securing techniques and that other techniques may be used without departing from the scope of the invention. The substantially square cross-section prevents rotation of the reinforcing members 20, 22. Furthermore, a reinforcing member may be inserted with any of the flat surfaces up. This reduces the need for an alignment step during assembly. However, other cross-sections may be used. In embodiments, the reinforcing members 20, 22 are hollow, solid, or of H-section profile.

[0056] It will be appreciated that with the reinforcing members 20, 22 secured in position, the reinforcing members 20, 22 serve to secure the panel components 16, 18 to one another. Furthermore, they provide reinforcement or strengthening to the panel 12, resisting bending or deformation of parts thereof. The position of the reinforcing members 20, 22 near the upper and lower edges, respectively, provides a climb-impeding configuration because of the absence of stepping surfaces between the upper and lower rail.

[0057] Upright reinforcing members 36, 38 are located within the hollow uprights 30, and have the feet 14 fitted to the lower ends thereof. The upright reinforcing members 36, 38 are of circular cross-sectional shape and are free to rotate relative to the associated uprights 30. Consequently, the feet 14 attached thereto may be rotated between in use and stowed positions. The upright reinforcing members may have other suitable profiles, for instance a square profile.

[0058] Turning to FIGS. 11 to 17, another embodiment of a temporary barrier 10A is illustrated. The temporary barrier 10A is similar to the above-described temporary barrier 10. The temporary barrier 10A comprises two types of barrier panel components. In FIGS. 11 to 17, numerals with a suffix -A and same numeral as in FIGS. 1-10 are used to identify similar components.

[0059] The temporary barrier 10A comprises a barrier panel 12A supported on two feet 14A. The barrier panel 12A comprises two end panel components 16A which are identical to each other and constitute a first type of panel component, and a plurality (here: six) of mid panel components 18A that are identical to each other and constitute a second type of panel component. The panel components 16A and 18A are arranged in side-by-side configuration and secured in succession by an upper reinforcement member 20A and a lower reinforcement member 22A, although it will be understood that the lower reinforcement member 22A may be optional. The end panel components 16A are reinforced by upright reinforcing members 36A and 38A, respectively. The panel components 16A and 18A are of moulded plastics material form manufactured, for instance, by injection moulding or compression moulding. Each of the panels is of smaller construction than the entire barrier panel 10, rendering it more readily suitable for manufacture by moulding.

[0060] As can be imagined, any number of mid-panel components, or no mid-panel component, may be used to manufacture a barrier panel of varying length. The FIG. 11 embodiment comprises eight panel components each about one eight of the width of the barrier panel width of known metal temporary barriers, namely six mid-panel components and two end-panel components.

[0061] FIGS. 11 and 12 show two connector rings 42A on one end panel component and two connector hooks 44A on the opposite end panel component. The connector rings and connector hooks constitute connectors for end-to-end engagement of a series of panels. The connectors may correspond to those of known metal barriers such that the temporary barrier of the invention is compatible in size and end-to-end connection with known metal temporary barriers.

[0062] By providing the hooks and loops as attachable components, this allows the same mould to be used for both end barrier panel components and configuring one end panel component as hooked end and another end panel component as loop end. Preferably, each end panel component is provided with at least two connectors, e.g. two hooks and two loops, to provide a relatively stable quasi-hinged end-to-end connection. Preferably the hooks and loops are engagable with a reasonable degree of play to allow adjacent connected panels to tilt relative to each other while connected. This facilitates the provision of a series of connected barrier panels on uneven terrain.

[0063] FIG. 13 illustrates a front view of an end panel component 16A, and FIG. 14 illustrates a front view of a mid-panel component 18A. Each component comprises an upper rail 24A and a lower rail 26A. The upper and lower rails 24A and 26A are similar to the rails described in relation to FIGS. 7 to 10, in that they are formed with windows arranged on alternating sides of the fence panel component such that the rails 24A, 26A are of shut-through form suitable for moulding techniques. FIG. 16 shows a section through an upper rail 24A illustrating at the right-hand side (in the reading orientation of FIG. 16) a window 32A. The end-panel component 18A comprises an end rail 28A with an H-profile, as described above in relation to FIG. 7. Partway along the length of the end rail 28A, one or more (here: two on either side of the panel) seating surfaces 46A are provided to facilitate the mounting of panel-to-panel connectors such as connector hooks 44A (see FIG. 12) or connector rings 42A (see FIG. 12). The end panel component 16A comprises a foot adapter 48A extending from the lower rail 26A in extension of one of the uprights 30A that is aligned with the associated foot 14A. The foot adapter 48A is hollow, of a shape to receive a reinforcing member 36, 38. The exterior silhouette of the foot adapter 48A may be round or otherwise dimensioned to engage a socket in a foot 14A. The foot adapter 48 may include abutment surfaces that limit axial rotation of a foot 14A. For instance, the axial rotation may be limited to a 90 degree range or to a 180 degree range such that a foot 14A may be rotated into a stowed position in which it lies flat with the barrier panel or into an extended position in which it extends practically perpendicular to the barrier panel. A 90 degree rotation range may be suitable for a symmetrical foot and will help ensure that a foot is correctly aligned in either a stowed or extended position when the abutment surface is hit. A 180 degree rotation may be appropriate for asymmetrical feet.

[0064] The adapter 48A may be integral with a barrier panel component, e.g. integrally moulded. The adapter 48A may be fitted to the barrier panel component after moulding. In that case, the barrier panel component may have rotational symmetry about the horizontal axis, as it may be imagined, such that the end panel barrier components and any mid panel barrier components may be assembled with any side up and the foot adapters 48A are fitted post assembly.

[0065] The mid panel component 18A illustrated in FIG. 14 comprises two uprights 30 and so exhibits sufficient stiffness for handling during manufacture of the barrier panel. By providing fewer uprights 30A per panel component, e.g. two uprights 30A as shown in FIG. 14, the manufacturing process is more resilient against an occasional manufacturing error in one of the uprights 30, in that a manufacturing error in one upright affects only one easily replaceable component of the entire barrier panel. However, mid-barrier panels with different numbers of uprights may be used in the invention. The uprights 30A are of H-shaped cross-section as illustrated in FIG. 15, but may have other suitable cross-sections.

[0066] The mid panel component 18A has two-fold symmetry in the vertical and horizontal direction. This facilitates the assembly of a barrier panel 10A because the mid panel component 18A will be appropriately orientated with either side up or down and with either side left or right.

[0067] In embodiments, the upright reinforcing members 36, 38 are of box or H-profile cross-section and may be of rectangular or square profile. The upright reinforcing members 36, 38 may be solid or hollow. If the hollow channel of the upright 30 is generally rectangular, a corresponding rectangular and square profile of the upright reinforcing member provides a closer location of the reinforcing members 36, 38 at the windows 34. This improves visibility of contrasting colours, particularly if it is considered that the reinforcing member may already, by virtue of it being located in a channel, be recessed from the outer upright surface. The closer location of surfaces of the reinforcing members 36, 38 reduces the gaps that may otherwise be present with round reinforcing members, which reduces the risk of entrapment or the gaps being filled with litter. If the feet 14 are provided with round profile sockets to receive the reinforcing members, the feet are still rotatable even with non-round reinforcing members. Alternatively, the channel and upright reinforcing members 36, 38 may have a round profile.

[0068] The presence of the upright reinforcing members 36, 38 further strengthens or reinforces the panel 12.

[0069] The upright reinforcing members 36, 38, like the reinforcing members 20, 22, are preferably of fibre reinforced plastics material form, for example manufactured by pultrusion or extrusion.

[0070] In embodiments, the reinforcing members 20, 22 are of a length no longer than the distance between the upright reinforcing members 36, 38, so that the upright reinforcing members 36, 38 can be fitted before or after assembly of the two panel components 16, 18.

[0071] In embodiments, the upper reinforcing member 20A is longer than the lower reinforcing member 22A. For instance, the upper reinforcing member 20A may be longer than the distance between the upright reinforcing members 36A, 38A to provide increased stability of the upper rail 24A.

[0072] As illustrated in FIG. 7, the end most upright 30 may be formed with projecting features 40 arranged to cooperate with the end most upright 30 of the other of the panel components, in use. The arrangement of projecting features 40 may be self-complementary. Alternatively, as illustrated in FIG. 14, the end most uprights 30A are arranged such that they need not come into abutment with those of adjacent barrier panel components.

[0073] FIG. 18 illustrates another embodiment of a temporary barrier 10B. The temporary barrier 10B is similar to the above-described temporary barriers 10 and 10A. In FIG. 18, numerals with a suffix -B are used to identify similar components as in the preceding embodiments.

[0074] The temporary barrier 10B comprises a barrier panel 12B, which comprises two rows, a lower row 17L and an upper row 17U, each row comprising two panel components 16B side-by-side, such there is a total of four panel components 16B. In the present example, each of the panel components 16B is identical, although this is not necessarily the case in every embodiment. Each panel components 16B is of generally rectangular, approximately square shape and comprises two outer rails, one outer rail at a horizontal edge and one outer rail on a vertical edge. The panel components 16B are arranged and rotated such that the inner edges of each panel components 16B face each other and the outer rails are at the outer edge of the barrier panel 12B. The rails are hollow and provided with windows. When assembled, the two outer edges at the top of the panel components 16B in the upper row 17U form an upper rail 24B, receiving an upper reinforcement member 20B. The outer edges at the side of the panel components 16B in the upper row 17U and in the lower row 17L provide a hollow upright rail, one hollow upright rail at either end of the barrier panel 12B, to receive upright reinforcing members 36B and 38B. Likewise, the two outer edges at the base of the panel components 16B in the lower row 17L form a lower rail 22B, receiving a lower reinforcement member 22B. The upper reinforcement member 20B is received within the upper rail 24B but portions of it are visible through windows 32B in the outer edges. Likewise, the upright reinforcing members 36B and 38B are visible through windows 34B in the outer edges, and the lower reinforcing member 22B received in the lower rail 26B is visible through windows 32B in the outer edges.

[0075] Between the upper row 17U and the lower row 17L there is provided a central reinforcing member 21B connecting the two rows. This provides stability to the temporary barrier 10B. Although not illustrated, the edges of the barrier panels 16B could be configured with alternatingly offset walls structures or hoops that can be engaged, for instance in alternating or overlapping fashion, to provide a common hollow channel for the central reinforcing member 21B. In that case, the walls structures may comprise windows in the manner of the upper and lower rails to allow portions of the central reinforcing member 21B to be visible.

[0076] As in the preceding figures, the upper and lower elongate reinforcing members 20B, 22B and upright reinforcing members 36B, 38B are illustrated with cross-hatching; the cross-hatching is intended to illustrate their visibility through alternating windows 32B and 34B in the barrier panel components 16B, but it will be understood that the reinforcing members may not necessarily exhibit a visible cross-hatching pattern, and may be of a single colour.

[0077] The panel components 16B are of moulded plastics material form manufactured, for instance, by injection moulding or compression moulding. Each of the panels 16B is of smaller construction than the entire barrier panel 10B, rendering it more readily suitable for manufacture by moulding.

[0078] The upright reinforcing members 36B and 38B extend from the lower row 17L to provide free ends 48B each for connection to a foot. Each free end 48B is provided with a foot structure 14B, and the foot structures 14B (here showing two feet 14B) can be slotted into a further support structure such as a base block.

[0079] Although described a 2 by 2 arrangement, any number of barrier panels may be provided side-by-side in a row. The number of barrier panels per row may differ. The temporary barrier 10B comprises panels of about 1×1 metre side length and measures about 2×2 metres. Several of such barrier panels 10B may be arranged, side-by-side, to form a temporary fence of any length. Although the barrier panel 1B is described with a central reinforcing member 21B that extends horizontally, some barrier panels may comprise a plurality of upright reinforcing members. A barrier panel may comprise both horizontal and vertical reinforcing members if arranged in a suitable way, for instance on opposite sides of the barrier panel to allow them to cross. Likewise, a barrier panel may comprise one or more diagonal reinforcing members, for instance two diagonal reinforcing members.

[0080] The temporary barrier 10, 10A and 10B described hereinbefore are advantageous in that, as it is of plastics material form, they are of relatively low weight and are of relatively low cost form. In the arrangement shown, the feet 14 are of low profile form and so do not present a significant trip hazard to pedestrians in the vicinity of the barrier. The plastics material of the barrier is of relatively good resilience, and so if subject to relatively low magnitude impacts will tend to deflect and subsequently return to substantially its original form. The manner in which it is fabricated lends itself to the use of injection moulding techniques through each component part being of relatively small dimensions.

[0081] Whilst selected forms of barrier are described and illustrated hereinbefore, a number of modifications and alterations may be made thereto without departing from the scope of the invention. By way of example, the rails could be of H-shaped section, with the reinforcing members attached to faces thereof rather than located within the hollow interior of the rails as illustrated. The reinforcing members, rails and uprights may be of other cross-sectional shapes to those illustrated. For instance, the rails and/or uprights may be of round cross-section to receive round reinforcing members. The reinforcing members may be solid or hollow. The reinforcing members may comprise hollow channels to receive additional reinforcing structures. The reinforcing members, i.e. the upper reinforcing member, one or both upright reinforcing members, and, if present, the lower reinforcing member may be made from or comprise metal.

[0082] If desired, the feet could be fitted to the lower rail rather than to the upright reinforcing members. The barrier panel may be provided with any number of feet. A panel with two feet allows for a configuration with the feet connected at the end panels.

[0083] Features described in relation to the FIG. 11 barrier panel may be used in the FIG. 1 barrier panel, and vice versa.

[0084] For instance, although not shown in FIGS. 1 to 10, once the barrier panel components are assembled, the barrier panel 10 may be provided with connectors such as hooks and loops for end-to-end engagement of a series of barrier panels.

[0085] Barrier panels of the type described herein may have any length. A typical length of a pedestrian barrier may be in the region of 1.5 to 2 meters. Due to their likely length and because such barriers may be installed in uneven terrain they are described herein as being supported on feet. The feet may be constituted by base block elements, particularly if the barrier panels are to be installed on relatively even ground. However, the barrier panel may also be supported on a unitary base block of sufficient dimensions. Such a base block may itself comprise feet, for instance integral with the base block.

[0086] A number of other modifications may be made without departing from the scope of the invention as defined by the appended claims.
