Regulation 3.2 AUG-TRAILIA Patents Act 1990 COML ET .PECFECADON STANDARD PATENT APPLICANT: CUNNINGHAM, Michael INVENTION TiTLE: BARRIER SYSTEM The following statement is a full description of this invention, including the best method of performing it known to me: - -2 BARRIER SYSTEM Field of the Invention This invention generally relates to a barrier and particular is concerned with safety barriers for providing both visual and physical barriers. Background to the Invention It sometimes happens that extensive road work, for example during maintenance, repair or expansion of a section of road, is carried out on the section of road which may tak3 some time to complete. Typically the section of road affected during such typcs of road work is shielded off to protect personnel working on the road area as well as motorists using a part of the road not being affected by the road work. One way of shielding off the section of road being affected by the road works is to assemble a barrier at least between the work area and an adjacent road surface still open to traffic. The time required to assemble the barrier should ideally be kept to a minimum thereby reducing the disruption in flow of traffic which may be caused in a part of the road not being affected by the road works. One type of barrier which can be used is a shaded cloth covering over a wire fence. Constructing such a barrier is relatively simple and ordinary does not require a great amount of time to assemble the barrier. However, in order to allow the barrier of this type to be assembled relatively quickly, the barrier is assembled from components which are relatively light. This may cause reduction of the overall weight of the barrier which could lead to the barrier being easily influenced by wind or air blowing onto the barrier. Other barriers include fencing with heavy footings for receiving loosely fitting poles with flexible material or flexible fencing extending therebetween. These barriers take much time to assemble. However the main problem is the poles often are dislodged from the footings due to the height relative to the footings or are readily knocked over and then are held by other poles and the flexible material or flexible fencing. This creates an unsafe barrier and aids damage to the flexible material or flexible fencing. Summary of the Invention Accordingly, it is an aim of the present invention to overcome or substantially ameliorate one or more of the disadvantages of the prior art by providing a barrier system in the form of rigid -3 fencing that can be used to provide a physical and visual barrier which is easy to erect and dismantle. The invention provides a barrier system which includes at least two spaced apart elongate posts and a panel which in use extends between the two elongate posts; and wherein each elongate post includes a support arrangement which is capable of receiving an end of the panel and which includes at least a first pair of spaced apart side stop formations and a bottom stop formation; and wherein in use each end of the panel extends from a respective bottom stop formation in between a respective at least first pair of spaced apart side stop formations thereby allowing the panel to be supported by the spaced apart elongate posts. The invention provides a barrier system which can be relatively easily constructed by fitting a panel between two spaced apart elongate posts without requiring the use of fasteners or the like. Each elongate post carries a support arrangement which includes at least a first pair of spaced apart side stop formations which allow an end of the panel to be positioned therebetween thereby allowing the panel to be supported in the operative position, which typically is a substantially vertical orientation, by the two spaced apart elongate posts. The support arrangement may further include a bottom stop formation which allows a lower section of the panel to rest at each of the ends of the panel on the respective bottom stop formation. Thus, each end of the panel is supported by the support arrangement on opposed sides of the panel as well as at a lower portion of the ends of the panel. The panel is therefore carried by the bottom stop formations and is prevented from pivotal movement about the lower section of the panel by the first pair of spaced apart side stop formations. The support arrangement therefore allows engagement of each end of the panel with a respective support arrangement by movement of the respective ends of the panel longitudinally along a respective elongate post. In other words, opposed ends of the panel is slid along a respective adjacent elongate post until the lower section of the panel abuts the bottom stop formation. A barrier system which includes at least two spaced apart elongate posts and a panel which in use extends between the two elongate posts; each of the at least two spaced apart elongate posts extend from a supporting means; and wherein each elongate post includes a support arrangement each of which is capable of receiving an end of the panel so that the panel in use is supported in an operative position by the spaced apart elongate posts. The invention also provides a barrier system in the form of rigid fencing for mounting to at least one removable supporting means able to provide a momentum inhibiting barrier to vehicles, the barrier system including: -.4 a. at least one elongate post for mounting substantially upright to the supporting means; and b. a panel removably mountable to the at least one post above the removable supporting means; and wherein the elongate post includes a support arrangement which is capablo of receiving a portion of the panel so that the parel in use is supported in an operative position by the elongate post; whereby the barrier system is easy to erect and dismantle and provide a substantial visual barrier and a physical barrier. The invention provides a barrier system which includes at least two spaced apart elongate posts and a panel which in use extends between the two elongate posts; and wherein each elongate post includes a support arrangement each of which is capable of receiving an end of the panel so that the panel in use is supported in an operative position by the spaced apart elongate posts. Each of the at least two spaced apart elongate posts my have any suitable profile which will allow the panel to extend between and supported by the two spaced apart elongate posts. For example, each of the at least two spaced apart elongate posts may have a cross sectional profile which is substantial square, rectangular oval or the like. In one example of the invention, a channel is formed at least on one side of each of the at least two spaced apart elongate posts so that sides of the channel form the first pair of side stop formations. In another example of the invention each of the at least two spaced apart elongate posts of formed to have an upper part and the lower part from which the upper part extends. The parts may be secured to each other using any suitable technique such as welding, fasteners or the like. In another example of the invention the first and second parts of formed from one piece of material which is shaped to form the upper and lower parts. In a further example of the invention the lower part is angled relatively to the upper part so that the upper part extends substantially vertical once the lower parts is anchored. In a further example of the invention the lower part is secured to a supporting means. The supporting means is such that it allows the at least two spaced apart elongate posts to extend from the supporting means in such a way so that the barrier can be assembled on the supporting means with a predetermined degree of stability. For example, the supporting means may be a cement barrier or fence which may be formed from one continuous section of cement or assembled from a number of sections or blocks. The cement fence may also be a permanent fixture or a temporary installation.
-5 The lower part of each of the at least two spaced apart elongate posts may also be secured to the supporting means using any suitable technique. For example, suitable fasteners may be used to secure the lower part to the supporting means. The fasteners may be embedded during manufacture of the supporting means or may be fitted to holes, which may have boen formed during manufacture of the supporting means or which may have be formed through the supporting means during or after manufacture the supporting means. so that the fasteners extend through the supporting means. In one example of the invention the upper part of each of the at least two spaced apart elongate posts carry the support arrangement. Each of the at least two spaced apart elongate posts may be manufactured from any suitable material which will increase the durability, strength, and lifcspan cf the at least two spaced apart elongate posts. For example, each of the at least two spaced apart elongate posts may be manufactured from a metal such as mild or stainless steel or plastic. The panel may be constructed using any suitable any suitable technique to have any suitable shaped. In one example of the invention, the panel is formed, when viewed from a side, to have a profile which is substantially rectangular although other shapes can equally be employed such as square, oval or the like. In one example of the invention, the panel is formed from a frame to which is fitted a filler sheet. The filler sheet may be formed from any suitable material which will reduce the level of ease with which a person, standing on an outside of the barrier, to be able to see through the barrier and see, for example, a worksite which is shielded off by the barrier of the present invention. For example, the filler sheet may be in the form of a mesh material which may be covered with a material such as a shaded cloth. The mesh of the filler sheet may also be such that it makes it difficult to see through the filler sheet. Alternatively, the filler sheet may be formed from an integral piece of material which may be manufactured from a suitable would, metal, or plastic. When an integral piece of material is used to manufacture the filler sheet, suitable apertures may be formed through the filler sheet to allow air to pass through the barrier thereby decreasing a force which may be exerted on components of the barrier as a result of air flowing against the barrier. The frame and filler sheet may be secured or attached to each other using any suitable technique such as welding, fasteners, rivets or the like. In one example of the invention, the frame is constructed in any suitable way and maybe manufactured from an integral piece of material or from several sections of material. When several sections of material is used to -6 assemble the frame, any suitable technique may be used to secure the sections of material to each other such as welding, fasteners or the like. In one example of the invention, the support arrangement may include at least a first pair of spaced apart side stop formations through which the at least two spaced apart elongate posts is able to maintain the panel in use in the operative position. In one example of the invention, the at least first pair of spaced apart side stop formations are formed by material from or one or more components carried by each of the at least two spaced apart elongate posts. In the example when a channel is formed on at least one side of each of the at least two spaced apart elongate posts, sides of the channel form the first pair side stop formations. In a further example of the invention, each formation of the two spaccd apart sida stop formations is formed by a member which extends from a side of each of the at least two elongate posts. For example, the member may be a piece of flat bar which is secured to a respective post so that opposed ends of the bar project from opposed sides of the post. The piece of flat bar may be secured to the post using any suitable technique such as welding, fasteners or the like. Alternatively, in a further example of the invention, the member may have any other suitable shape and maybe a piece of square bar, angle iron or the like provided that the member used has a suitable shape so that a portion of the member stands proud from a side of the post. In a further example of the invention, formations of the spaced apart side stop formations are carried by one member which has the spaced apart formations formed at spaced apart locations on the member. The spaced apart formations may be may be formed in any suitable way, for example using material from the one member or using parts which are attached to the one member. In the example of the invention when the support arrangement includes a bottom stop formation, a lower section of the panel rests against the bottom stop portion when the panel is supported by the at least two spaced apart elongate posts in the operative position. Alternatively, when the support arrangement only includes at least a first pair of spaced apart side stop formations, the lower section of the panel may rest against a supporting means which carries the at least two spaced apart elongate posts. In a further example of the invention, the support arrangement includes a second pair of spaced apart side support formations which are spaced apart from the first pair of spaced apart side support formations. In a further example of the invention, the first pair of spaced -7 apart side stop formations are positioned at one end of each of the at least two spaced apart elongate posts and the second pair of spaced apart side stop formations are positioned at an opposed end of each of the at least two spaced apart elongate posts. For example, the first pair of spaced parts side stop formations may be positioned at an upper end of the upper part of each of the at least two spaced apart elongate posts and the second pair of spaced apart side stop formations may position at a lower end of the upper part of each of the at least two spaced apart elongate posts. In a further example of the invention, the support arrangement may include a third stop formation which is positioned on each of the at least two spaced apart elongate posts at a position which is intermediate to the first and second pairs of spaced apart side stop formations. The third stop formation may include any one s op formation which is positioned at one side of each off the at least two spaced apart elongate posts. When the support arrangement includes the first and second pairs of side stop formations and the third side stop formations, and when each of the two spaced apart elongate posts is viewed along a length of the post, the first and second pairs of spaced apart side stop formations and the third side stop formation form of a channel which is capable of accommodating an end of the panel. The invention provides a barrier system which includes at least two spaced apart elongate posts and a panel of which each end is associated with a respective adjacent elongate post so that the panel extends in use between the two elongate posts; and wherein each elongate post includes a support arrangement which is capable of receiving an end of the panel and which includes at least one pair of spaced apart side stop formations; and wherein in use each end of the panel is fitted to a respective support arrangement so that the end extends between the at least first pair of spaced apart side stop formations thereby allowing the panel to be supported by the at least two spaced apart elongate posts. The invention also provides a method for constructing a barrier system, the method including the steps of securing a first elongate post to a supporting means; securing a second elongate post to the supporting means at a position which is spaced apart from the first elongate post; and sliding a panel in between the first and second spaced apart elongate posts so that each end of the panel is positioned between at least a first pair of spaced apart side stop formations of a support arrangement which is carried by each of the first and second elongate posts until a lower section of the panel abuts a bottom stop formation of each of the support arrangements so that the panel is supported at opposed ends by the first and second elongate posts through the bottom stop formation and by the first pair of spaced apart side stop formations which prevent pivotal movement of the panel about the lower section.

-11 Description of Illustrated Embodiment of the Invention In this embodiment illustrated in Figures 1, 2 and 3, the invention provides a barrier system 10 in the form of rigid fencing, having removable supporting means 13 able to provide a momentum inhibiting barrier to vehicles, two elongate posts 21 for mounting substantially upright to the supporting means at either end of the supporting means 13 and a substantially non-transparent elongated panel 11 removably mountable to iho removable sunoortino means 13. The posts 21 include two portions 22, 23, a first portion having a shape substantially complementary to the outer structure of the supporting means and a second portion having a substantially linear section angled to the first portion to provide a substantially upright orientation when the first portion is mounted to the supporting means. The p>inel 11 includes a rigidity formation to increase rigidity and limit flex and the panel further including wind directing means for decreasing torsional wind pressures on the panel. The barrier system includes at least one elongate post, 21, with a "U" shaped cross section for mounting substantially upright to a supporting means, 13. The posts are held in place by the supporting means 13 such as a removable fillable container that water or a cementitious block, the post is fixedly mounted to the removable concrete footing. The posts have a substantially rigid polymer planar panel, 11, removably mounted to them such that the barrier system can be used to form a physical barrier that also provides a substantial visual barrier. The panel is substantially rectangular in shape with two sets of edges. One edge set defines the length of the rectangle, while the other set defines the height which is substantially in the range of 35% to 45% of the length of the panel. The length of the panel is in the order of three meters. The barrier system 10 is mounted together by a mounting means that includes an inverted hook, 32, on the posts, 21, and a receiving structure formed as a receiving sleeve, 31, on the panel, 11,. The inverted hooks are passed into the receiving sleeve when mounting to suspend the panel from the posts. Once the panel has been mounted onto the inverted hooks on the support posts, fasteners can engage with the inverted hooks to hold the panel in place. The panel includes a plurality of apertures, 19, that allow the wind to pass through which will also substantially restrict visibility through the panel. These apertures are arranged in rows and are spaced by a distance that can substantially range from 5% to 10% of the panel height.
-12 The panel, 11, also includes at least one protruding ridge, 15, that is elongate with a length and a width and is formed integrally with the panel. A ridge runs substantially parallel to the length of the panel and their width is in the range of 10% to 20% of the panel height. When a plurality of ridges is used on the panel, the total sum of the ridges heights is in the range of 25% to 35% of the panel height. These ridges are included on the panel to provide extra strength. The posts, 21, are divided into two portions defined by a bend. The first portion, 22, has a shape substantially complementary to the outer structure of the supporting means. The second portion, 23, has a substantially linear section angled to the first portion to provide a substantially upright orientation when the first portion is mounted to ihe supporting means, 13. The second portion of the post includes the mounting means in the form or inverted hooks, 32. To assembb- the barrier system a person would follow the following steps: a) beginning with providing a substantially rigid panel, 11, and at least one post, 21, including two portions. b) The first portion, 22, having a shape substantially complementary to the outer structure of the supporting means and a second portion, 23, having a substantially linear section angled to the first portion to provide a substantially upright orientation when the first portion is mounted to the supporting means. c) The at least one post includes at least one mounting means in the form of an inverted hook, 32, and the panel includes at least one receiving structure formed as a receiving sleeve, 31. d) The panel, 11, is then mounted to the at least one post, 21, by passing the inverted hooks through receiving sleeves and holding on the rigid sheet such that the barrier system can be used to provide a visual barrier and a physical barrier to a supporting moans such as a concrete footing. e) The support posts would be aligned such that they extend substantially vertical from the supporting means, 13, which is a cementitious block or concrete footing. f) The support posts will need to be mounted to the supporting means, this can either be done by releasably mounting them to the supporting means, or by fixing them to the supporting means. g) If the posts, 21, are to be releasably mounted to the supporting means, they will be attached by a method that will not make use of fasters such as hooks. h) Once this was done, the rigid panel would be mounted to the support by passing the inverted hooks through the receiving sleeves, 31, on the rigid panel.
- 13 i) This would allow the barrier system to be used to provide at least a partial visual barrier and a physical barrier to passing traffic and pedestrians. j) The assembly method also includes fixedly mounting the first portion, 22, of the at least one posts to the mounting means which is a portable concrete foot. A method of manufacturing a barrier system includes the steps of: providing a first material that is extrudable and rigid that is then formed and shaped to size, thickness, shape and form that is usable as a panel, 11. The plurality of apertures, 19, receiving sleeves, 31, and the ridges, 15, are made during the forming and shaping of the material. o A second material is then provided that is malleable and rigid that is then formed and shaped to size, thickness, shape and form that is usable as a post, 21, with a "c" cross section and has two portions, 22 and 23. o The plurality of mounting means in the form of inverted hooks, 32, is made during the forming and shaping. This method of manufacture will make a barrier system is provided which is capable of being used as a visual barrier and a physical barrier to passing vehicles and pedestrians. The method for manufacturing the barrier system includes the plurality of apertures, 19, being made post forming and shaping of the material of the barrier system. These apertures can be made by a number of methods such as cutting or punching. The receiving sleeve, 31, is made using a method of manufacture which happens post forming and shaping of the material. These receiving sleeves can be made by a number of methods such as cutting or punching. The method of manufacturing the barrier system includes the shape of the "c" section of the post, 21, being formed post forming and shaping of the material of the barrier system. The forming of the support post can be achieved by bending or extruding. The inverted hooks, 32, on the post, 21, made during the method of manufacture of the barrier system can happen post forming and shaping of the material. The manufacturing process used to make these inverted hooks can be either be punching and bending or cutting and bending. The two portions of the post, 22 and 23, are formed during the method of manufacture of the barrier system happens during the forming and shaping of the material. These two portions of the post can be made by bending the post.
- 14 Figures 4 to 8 illustrate a variation 100 of a barrier system according to the invention which includes two spaced apart elongate posts 112 and a panel 114 which in use extend' between the two spaced apart elongate posts. Each of the two spaced apart elongate pusts 112 has an upper part 116 and a lower part 118 from which the upper part extends. Laci of the two spaced apart elongate posts carry a support arrangement 120 which is capable of receiving an end 124 of the panel. For simplification purposes reference will only be made hereinafter to one of The two spaced apart elongate posts. However, since each of the two spaced apart elongate posts is substantially identical, the description of the invention as far as it at relates to the elongate post should be taken for both of the two spaced apart elongate posts. Rcf-:rring in particular to Figures 4 and 5, the support arrangemnert 120 has a first pair of spaced apart side stop formations 126, which is positioned at an upper end 128 of the upper part 116, a second pair of spaced apart side stop formations 130 which is positioned at an opposed, lower end 134 of the upper part 116, a third stop formation 136 which is positioned on the upper apart between the first and second pair of spaced apart side stop formations, and a bottom stop formation 138 which is positioned on the upper part at a position which is adjacent the lower part 118. The first and second pair of spaced apart side stop formations 126 and 130 each has a first member 140 which is positioned on an outer surface 144 of the upper part 116 and a second member 146 which is positioned on an inner surface 148 of the upper part 116. The third stop formation 136 has only the second member 146. Each of the first and second members 140 and 146 has opposed ends 150 each of which extends from opposed sides 154 of the upper part 116. The bottom stop formation 138 has two angled members 156 each of which is positioned on one of the opposed sides 154 of the upper part 116. As is particularly evident from Figure 5, the lower part 118 of the elongate post 112 is angled relatively to the upper part 116 thereby allowing the upper part 116 substantially vertical from a supporting means or cements block 158 to which the lower part is secured to using suitable fasteners, not shown. The lower part is secured to an angled surface 160 of the cement block at a position so that the bottom stop formation 138 is positioned in proximity to a top part 164 of the cement block. This allows a lower section 166 of the panel 114 to be positioned adjacent to the top part once the barrier system 100 is assembled so that a gap 168 (see Figure 8) is kept to a minimum. This reduces the likelihood the barrier system 100 having sections through which a person, not shown, can see through when looking at the barrier system.
-15 Figure 6 shows the panel 114. The panel has a frame 170 which encloses filler sheet 174 which, in the illustrated example, is a mesh material which is to be covered by a shaded cloin 176. Figure 8 illustrates the supporting of the panel 114 by the post 112 in an operative position 178 in which the panel extends substantially vertical from the cement block 158. The end 124 of the panel is fitted to the support arrangement 120 so that the end 124 extends from the bottom stop formations 138 in such a way so that the end is positioned between the first and second members 140 and 146 of the first and second pairs of spaced apart side stop formations 126 and 130 and is positioned adjacent the second member 146 of the third stop formation 136. The orientation of the first and second members 140 and 146 of is better shown in Figure 7 in which the post 112 has been removed to simplify the drawing. Thus, a lower portion 180 of the panel 112 is rests on one of the angled members 156 of the bottom stop formation 133 so that the end 124 of the panel nestles between the first and second members 140 and 146 of the first and second pairs of spaced apart side stop formations 126 and 130 thereby preventing pivotal movement 184 of the panel about the lower section 166 of the panel. The first and second members 140 and 146 therefore create a channel 186 which allows the end 124 of the panel to be slid longitudinally along the post 112 from the upper and 128 to the lower end 134 of the upper part 116 of the post. The post 112 has two support arrangements 120 since each of the members 140 and 146 of the first and second pairs of spaced apart side stop formations 126 and 130 of the third stop formation 136 extend across the outer surface 144 of the post so that the opposed ends 150 of the members project from the opposed sides of 154 of the post. Therefore, it is possible to register the end 124 of the panels 114 with other one of the support arrangements 120 carried by the opposed sides 154. The invention therefore provides a barrier system which allows a panel to be relatively easily fitted to elongate posts by sliding an end of the panel along a length of the post until a lower portion of the end rests on a bottom stop formation so that the end of the panel is held captive between first and second pairs of spaced apart side stop formations which prevent pivotal movement of the panel about a lower section of the panel. In other words, each elongate post carries a support arrangement, of which the first and second pairs of spaced apart side stop formations and the bottom stop formation form part of, which maintains the panel in use in an operative position. The elongate posts of the barrier system can also be secured to cement blocks ordinary used to demarcate a road work site thereby only requiring the fitment of the panel between adjacent pairs of elongate posts for the barrier system according to the invention to be assembled. This is likely to reduce time needed to -16 assemble the barrier system. Additionally, the panel is manufactured from a metal which reduces the likelihood of the panel inadvertently being moved against gravity to detach the panel from adjacent pairs of elongate posts. The support arrangement also has a third stop formation which is intermediate to the first and second pairs of spaced apart side stop formations which provide support to the panel at an intermediate position. While we have described herein a particular embodiment of a barrier system, it is further envisaged that other embodiments of the invention could exhibit any numbLr and combination of any one of the features previously described. However, it is to be understood that any variations and modifications can be made without departing from the spirit and scope thereof.
