DESCRIPTION
[0054] FIG. 1 is a side view of a temporary barrier 10. The temporary barrier 10 comprises a barrier panel 11, two supporting feet 12, a mounting surface 13 constituting a mounting location and a connector element 14.
[0055] As shown in FIG. 1, the barrier panel 11 has an oblong-shaped side profile comprising a first lateral end 16, a second lateral end 17, a base 19 and a top rail 18. The first and second lateral ends 16, 17 are separated by a distance defined by the panel's width, and the base 19 and top rail 18 are separated by a distance defined by the panel's height. The barrier panel 11 has a thickness (not shown in FIG. 1) which is much smaller than both the panel width and the panel height. The plane of the panel is understood to correspond to the width and height extension of the barrier panel 11. The first and second lateral ends 16, 17 are substantially straight and parallel in relation to each other and are generally vertically aligned when both supporting feet 12 rest on an underlying ground surface (not shown in FIG. 1). The base 19 and top rail 18 are substantially straight and parallel in relation to each other and are generally horizontally aligned when both supporting feet 12 rest on an underlying ground surface. Panels of this type are typically flat to allow them to be stacked for storage or transportation. However, it will be appreciated by those skilled in the art that the barrier panel 11 may have any shaped side profile. For example, the barrier panel 11 may have a side profile which is oval-shaped or irregularly-shaped. Some temporary barriers are of balcony shape with a wider footprint for increased stability. The barrier may be assembled from multiple panel components. Any such, barriers would be understood to include lateral ends for end-to-end connection of a series of barriers.
[0056] In FIG. 1, the panel 11 is of a grid-panel type with integrally moulded vertical posts spaced apart by a plurality of (here: six) openings 15. However, the barrier panel 11 may comprise more than six openings, fewer than six openings, or no openings (i.e. the panel 11 may be a continuously solid panel, as may be desirable to protect passers-by from debris or dust).
[0057] The barrier panel 11 may be manufactured from a moulded plastics material such as, for example, acrylonitrile butadiene styrene (ABS), polyethylene, polycarbonate, polyamide, or polypropylene. The barrier panel 11 may be manufactured from either a virgin plastic material or a recycled plastic material. The barrier panel 11 may be manufactured via any process known in the art such as, for example, blow moulding, injection moulding, or compression moulding.
[0058] The barrier panel 11 may include one or more strengthening members to improve the panel's strength and/or rigidity. The strengthening members may be manufactured from a different material to the barrier panel such as, for example, a stronger and/or more rigid plastics material, steel, aluminium or wood, or a fibre-reinforced composite material. The strengthening members may lie adjacent: the top rail 18, the base 19, the first lateral end 16, the second lateral end 17, one or more openings 15, or a combination of said locations.
[0059] As shown in FIG. 1, the temporary barrier 10 comprises a mounting surface 13 constituting a mounting location, located on a side face of the barrier panel 11 and adjacent the second lateral end 17 of the barrier panel 11. By side face, it is meant an outer surface of the barrier panel 11 which is at least partially defined by the first lateral end 16, the second lateral end 17, the base 19 and the top rail 18. Thus, a barrier panel will typically have two side faces, only one of which is shown in FIG. 1. A connector element 14 is affixed to the mounting surface 13. The connector element 14 extends laterally from second lateral end 17 of the barrier panel 11 such that it is able to connect in end-to-end fashion to an adjacent temporary barrier.
[0060] In FIG. 1, the mounting surface 13 is a distinct portion of the outer surface of the barrier panel 11 onto which a connector element 14 may be affixed. In other embodiments, the mounting surface 13 is comprised on a separate structure which has been affixed to the outer surface of the barrier panel 11. Said separate structure may be manufactured from a different material to the barrier panel 11 such as, for example, a different plastics material, steel, aluminium or wood, or a fibre-reinforced composite material. Said separate structure may be manufactured from a stronger material than the barrier panel 11. In some embodiments, the mounting surface 13 may be recessed into the outer surface of the barrier panel 11.
[0061] In some embodiments, the connector element 14 is manufactured from a different material to the barrier panel 11. For example, the connector element 14 may be manufactured from a different moulded plastics material to the barrier panel 11. Alternatively, the connector element 14 may be manufactured from a non-plastics material such as, for example, steel, aluminium, wood or a fibre-reinforced composite. The connector element 14 may be manufactured from, or reinforced with, a stronger material than the barrier panel 11. By stronger, it is meant that the connector element may be harder, more durable, more resilient and/or more rigid than the barrier panel.
[0062] In FIG. 1, the connector element 14 is affixed to the mounting surface 13 via rivets 20. However, it will be appreciated by those skilled in the art that the connector element 14 may be affixed to the mounting surface via any means well known in the art such as, for example, screws, a snap-fit arrangement, or a combination of two or more different affixing means.
[0063] In some embodiments, the connector element 14 is rotationally locked in relation to the barrier panel 11. In other embodiments, the connector element 14 is vertically fixed in position to prevent sliding up and down the barrier and allowed to rotate in relation to the barrier panel 11 about at least one axis of rotation. The locked, or fixed, engagement may be achieved by providing corresponding engagement features in the form of an arrangement of holes as attachment configuration of the connector element 14 and in the form of corresponding holes as fixture-receiving configuration of the outing surface 13.
[0064] In FIG. 1, the mounting surface 13 is shown to be rectangular. However, it will be appreciated by those skilled in the art that the mounting surface could be of any size and shape which is suitable for accommodating the connector element 14 which is to be affixed to it. Particularly if integrally moulded with the barrier panel 11, the mounting surface may comprise tapered and curved contours to facilitate manufacture by moulding.
[0065] Referring to FIGS. 2a and 2b, FIG. 2a shows a side view of two temporary barriers 20 according to another embodiment of the invention connected in end-to-end fashion. The same reference numerals are used in FIGS. 1 and 2a for corresponding elements without repeating the description thereof. Each temporary barrier 20 comprises a first mounting surface 23a adjacent the first lateral end 16 of the barrier panel 11, and a second mounting surface 23b adjacent the second lateral end 17 of the barrier panel 11. In the embodiment shown in FIG. 2a, the first and second mounting surfaces 23a, 23b are located on a side face of the barrier panel 11. In the particular embodiment, the second mounting surface 23b is located at a different height (at a greater vertical distance from the base 19 of the barrier panel 11) than the first mounting surface 23a.
[0066] As shown in FIG. 2a, a first connector element 24a is affixed to the first mounting surface 23a and a second connector element 24b is affixed to the second mounting surface 23b. The first and second connector elements 24a, 24b may be affixed to the first and second mounting surfaces 23a, 23b via any of the affixing means previously described in relation to FIG. 1.
[0067] FIG. 2b shows an isolated perspective view of the first and second connector elements 24a, 24b shown in FIG. 2a. As shown in FIG. 2b, the first connector element 24a has a different configuration to the second connector element 24b. The first connector element 24a comprises a ring 25 and the second connector element 24b comprises a hook 26. The ring 25 is configured to receive the hook 26. It will be appreciated by those skilled in the art that any engaging configuration can be provided instead of the ring 25 and the hook 26 so that it can be provided that the first and second connector elements 24a, 24b are engageable in the lateral direction of the temporary barrier 20; the lateral direction of the temporary barrier 20 being defined as parallel to the width of the barrier panel 11. For example, the hook 26 may comprise a straight downwardly depending rod such as that shown comprised in the connector element 14 of FIG. 1. As a further example and as illustrated in FIG. 3b, the hook 36 may comprise a cylindrical structure constituting the hook end and the ring 35 may comprise a circular cuff configured to at least partially surround the cylindrical structure. This will be discussed in more detail below.
[0068] The temporary barrier 20 shown in FIG. 2a comprises first and second mounting surfaces 23a, 23b and first and second connector elements 24a, 24b located adjacent the first and second lateral ends 16, 17 of the barrier panel respectively. In some embodiments, the first and second mounting surfaces 23a, 23b and the first and second connector elements 24a, 24b may both be located at the same lateral end of the barrier panel 11. In said embodiments, the first and second mounting surfaces may be located on opposite side faces of the barrier panel 11 such that the first and second connector elements are offset from one another in a direction parallel to the barrier panel's thickness.
[0069] In some embodiments, the barrier panel 11 exhibits symmetry such that the mounting panels are on the same height. This facilitates manufacture if the temporary barrier can be assembled without regard to the orientation of the barrier panel. The barrier panel may comprise multiple mounting locations, e.g. a total of four mounting locations, or six mounting locations, near the base, near the centre, and near the top, on each of the left and right end of the barrier panel, such that the barrier panel is correctly oriented for assembly regardless of which edge is facing up or to a particular side. It will be understood that the barrier panel may have more mounting locations than connectors. Each mounting location may allow a connector to be affixed to it.
[0070] Referring to FIGS. 3a and 3b, FIG. 3a shows a side view of two temporary barriers 30 according to another embodiment of the invention connected in end-to-end fashion. The same reference numerals are used in FIGS. 1 and 3a for corresponding elements without repeating the description thereof. The temporary barrier 30 comprises a first mounting surface 33a located adjacent the first lateral end 16 of the barrier panel 11 and a second mounting surface 33b located adjacent the second lateral end 17 of the barrier panel 11. In the particular embodiment, the first and second mounting surfaces 33a, 33b are located at the same height from the base 19 of the barrier panel.
[0071] As shown in FIG. 3a, a first connector element 34a is affixed to the first mounting surface 33a and a second connector element 34b is affixed to the second mounting surface 33b. The first and second connector elements 34a, 34b may be affixed to the first and second mounting surfaces 33a, 33b via any of the affixing means previously described in relation to FIG. 1.
[0072] FIG. 3b shows an isolated perspective view of the first and second connector elements 34a, 34b shown in FIG. 3a. The first connector element 34a comprises a circular cuff 35 and the second connector element 34b comprises a cylindrical structure 36. The circular cuff 35 is configured to at least partially surround the cylindrical structure 36 such that the first and second connector elements 34a, 34b are interlocked in the lateral direction of the temporary barrier 30. In some embodiments, the cylindrical structure 36 and the circular cuff 35 are rotationally locked about an axis parallel to the longitudinal direction of the temporary barrier 30; the longitudinal direction being defined as parallel to the height of the barrier panel 11. In other embodiments, the circular cuff 35 is free to rotate about the cylindrical structure 36.
[0073] Referring to FIGS. 4a-4c, FIG. 4a shows a perspective view of a connector element mounting configuration according to another embodiment of the invention. The same reference numerals are used in FIGS. 1 and 4a-4c for corresponding elements without repeating the description thereof. The temporary barrier 40a comprises a mounting surface 43a adjacent a lateral end of the barrier panel 11. The mounting surface 43a is planar and is parallel to a plane passing through the two lateral ends 16, 17 of the barrier panel 11. In the particular embodiment, the mounting surface 43a is recessed into a side face of the barrier panel 11. However, it will be appreciated that in other embodiments, the mounting surface 43a may be flush with a side face of the barrier panel 11. The connector element 44a comprises an affixing portion 46a constituting a panel-engaging portion and a connecting portion 47a. In FIG. 4a, the connecting portion 47a is shown as a hook. However, the connecting portion 47a may alternatively be a ring or otherwise. The affixing portion 46a comprises a planar affixing surface 45a (obscured in FIG. 4a). When the connector element 44a is affixed to the mounting surface 43a, the planar affixing surface 45a abuts and lies adjacent to the planar mounting surface 43a. The connector element 44a may be affixed to the mounting surface 43a via any of the means previously described. The thickness of the affixing portion 46a, as defined in the direction normal to the planar affixing surface 45a, may be chosen to be substantially the same as the depth of the recessed mounting surface 43a.
[0074] FIG. 4b shows a perspective view of a connector element mounting configuration according to another embodiment of the invention. The temporary barrier 40b comprises a mounting surface 43b at a lateral end of the barrier panel 11. The mounting surface 43b is planar and is perpendicular to a plane passing through the two lateral ends 16, 17 of the barrier panel 11. In the particular embodiment, the mounting surface 43b is recessed into an end face of the barrier panel 11. By end face, it is meant an outer surface of the barrier panel 11 which is substantially perpendicular to the barrier panel's side faces and which has a surface normal which is parallel to the width of the barrier panel 11. However, it will be appreciated that in other embodiments, the mounting surface 43b may be flush with an end face of the barrier panel 11. The connector element 44b comprises an affixing portion 46b constituting a panel-engaging portion and a connecting portion 47b. In FIG. 4b, the connecting portion 47b is shown as a hook. However, the connecting portion 47b may alternatively be a ring or otherwise. The affixing portion 46b comprises a planar affixing surface 45b (obscured in FIG. 4b).

The connector element 44b may be affixed to the mounting surface 43b via any of the means previously described. The thickness of the affixing portion 46b, as defined in the direction normal to the planar affixing surface 45b, may be chosen to be substantially the same as the depth of the recessed mounting surface 43b.
[0075] FIG. 4c shows a perspective view of a connector element mounting configuration according to another embodiment of the invention. The temporary barrier 40c comprises a mounting location constituted by two surfaces, namely a first mounting surface 431c and a second mounting surface 432c (obscured in FIG. 4c). Both mounting surfaces 431c, 432c lie adjacent a lateral end of the barrier panel 11. The mounting surfaces 431c, 432c are planar and are parallel to a plane passing through the two lateral ends 16, 17 of the barrier panel 11. In the particular embodiment, the mounting surfaces 431c, 432c are recessed into the side faces of the barrier panel 11. However, it will be appreciated that in other embodiments, the mounting surfaces 431c, 432c may be flush with the side faces of the barrier panel 11. The surfaces of the mounting location may be provided with integrally moulded holes extending through the thickness of the barrier panel from one mounting surface 431c to the opposite mounting surface 432c. The connector element 44c comprises an affixing portion 46c constituting a panel-engaging portion and a connecting portion 47c. In FIG. 4c, the connecting portion 47c is shown as a hook. However, the connecting portion 47c may alternatively be a ring or otherwise. The affixing portion 46c comprises a first planar affixing surface 451c (obscured in FIG. 4c) and a second planar affixing surface 452c, which constitute the panel-engaging portion. When the connector element 44c is affixed to the mounting surfaces 431c, 432c, the first planar affixing surface 451c abuts and lies adjacent to the first planar mounting surface 431c and the second planar affixing surface 452c abuts and lies adjacent to the second planar mounting surface 432c. In the connector element mounting configuration shown in FIG. 4c, the connector element 44c sandwiches the mounting surfaces 431c, 432c comprised on the barrier panel 11. The connector element 44c may be affixed to the mounting surfaces 431c, 432c via any of the means previously described, for example may be affixed via prefabricated holes, without having to alter or damage the barrier panel mould. The overall thickness of the affixing portion 46c, as defined in the direction normal to the planar affixing surfaces 451c, 452c, may be chosen to be substantially the same as the thickness of the barrier panel 11.
[0076] Referring to FIG. 5, FIG. 5 shows a perspective view of a connector element mounting configuration according to another embodiment of the invention. The temporary barrier 50 comprises a mounting surface 53 at a lateral end of the barrier panel 51. The mounting surface 53 is curved about an axis which is parallel to the longitudinal direction of the temporary barrier 50. In the particular embodiment, the mounting surface 53 corresponds to the curved outer surface of a circular cylinder. However, it will be appreciated that the mounting surface 53 may correspond to any curved surface, such as, for example, the curved surface of a partial circular cylinder, the surface of a sphere or the curved surface of a partial sphere. In the particular embodiment, the mounting surface 53 is recessed into the outer surface of the lateral end of the barrier panel 51. However, it will be appreciated that in other embodiments, the mounting surface 53 may be flush with the outer surface of the lateral end of the barrier panel 11. The connector element 54 comprises an affixing portion 56 constituting a panel-engaging portion and a connecting portion 57. The affixing portion 56 comprises two flexible arms separated by a gap 58. The two arms are configured to be prised apart such that the gap 58 is wide enough to receive the mounting location 53. In FIG. 5, the connecting portion 57 is shown as a hook. However, the connecting portion 57 may alternatively be a ring or otherwise. The affixing portion 56 comprises a curved affixing surface 55. In the particular embodiment, the affixing portion 56 comprises a circular cuff with an inner circular affixing surface 55. The inner circular affixing surface 55 has a similar radius to the curved mounting surface 53. When the connector element 54 is affixed to the curved mounting surface 53, the curved affixing surface 55 at least partially conforms to and at least partially surrounds the curved mounting surface 53. The connector element 54 may be affixed to the mounting surface 53 via any of the means previously described. The thickness of the affixing portion 56, as defined in the direction normal to the curved affixing surface 55, may be chosen to be substantially the same as the depth of the recessed mounting surface 53. In some embodiments, the connector element 54 is rotationally locked with respect to the mounting surface 53.
[0077] One or more of the connector elements may extend in the extension of the plane of the panel, laterally beyond the footprint of the base, sufficiently to allow two adjacent temporary barriers to be connected at a right angle, such that four panels can be connected to form a square.
[0078] While the barrier panel has been depicted as fence-type panel with slots, variants of the barrier panel may be continuously solid to provide protection against dust or debris.
