Description

WO 2013/091027 PCT/AU2012/001607 1 A MOUNTING ARRANGEMENT FOR TACTILE INDICATORS FIELD OF THE INVENTION This invention relates to tactile systems. In particular, this invention 5 relates to a mounting arrangement for tactile indicators, and a tactile system that incorporates the mounting arrangement. The invention also relates to a method for mounting tactile indicators. BACKGROUND OF THE INVENTION 10 It should be noted that reference to the prior art herein is not to be taken as an acknowledgement that such prior art constitutes common general knowledge in the art. Tactile ground surface indicators are protrusions that are located on ground surfaces, or walking surfaces, on which blind or visually-impaired 15 people walk. Typically, tactile indicators are found in and around buildings and stairs, or along the side kerb of roads. The ability to forewarn the blind or visLially-impaired people of an upcoming obstruction or hazard is important. Tactile indicators provide the visually impaired or the blind with an indication of what will be encountered if they continue to walk in a particular direction. 20 This is particularly important when the environment, which surrounds an obstruction or hazard, does not provide the visually impaired with sufficient indication of the presence of an obstruction or hazard. Typically tactile indicators are arranged according to a grid pattern on the ground surface. For example, tactile dots are an arrangement of short, 25 discrete, disc like object. The prior art has an inherent problem in that it takes considerable skill, care and many man-hours for a person to arrange each of those disc-like objects, individually, in correct alignment on the ground surface. It is a time-consuming process to glue each dot, one by one, to the ground-surface. Often, in one square metre, there can sometimes be around 30 400 of these tactile indicators. Moreover, the distance between the dots is mandated by the respective country standards; hence, the person has to take great care to maintain the prescribed dimensions. For this reason, the financial cost of installing these grids or arrangements of tactile indicators is very high.
WO 2013/091027 PCT/AU2012/001607 2 Tactile indicators are typically retrofitted to floors by way of forming mounting holes or slots, as the case may be, in the floors and then mounting the tactile indicators in the holes or slots. This is also very labor intensive and costly. 5 Clearly it would be advantageous if a mounting arrangement for tactile indicators could be devised that helped to at least ameliorate some of the shortcomings described above. In particular, it would be beneficial to provide for a mounting arrangement that reduces the cost and man hours and that meets the requirements of respective countries in relation to tactile indicators. 10 Therefore there is an ongoing need for an alternative tactile system that facilitates ease of installation. SUMMARY OF THE INVENTION Accordingly, the invention broadly provides a mounting arrangement for 15 tactile indicators, the mounting arrangement being arranged for in situ casting in a settable material that forms a floor in a manner that allows mounting of the tactile indicators subsequent to forming the floor. The mounting arrangement may include a body that is formed from a synthetic plastics material which resists structural degradation when secured 20 in situ in a settable cementitious material. Instead, the body may be formed from a metal alloy material, for example for in situ casting into a road that is formed from a warm bitumen material. The body may include a plurality of tactile indicator mounts for cooperating with complementary mounting formations of tactile indicators. 25 The tactile indicator mounts may include a plurality of spaced apart juxtaposed elongated mounts having an operatively upper end opposite a lower end. Each elongated mount may be in the form of a circular cylindrical tubular formation defining an axially extending open ended passage for 30 receiving a complementary shaped and sized mounting formation of the tactile indicator. The passage may be a rebated shaft or is screw-threaded. In another embodiment, the tactile mounts may be in the form of elongated slotted formation that defines a slot for receiving blade-shaped mounting formations of tactile indicators.
WO 2013/091027 PCT/AU2012/001607 3 The body may include a spacing arrangement fixedly to retain the elongated mounts in their spaced apart relationship. The spacing arrangement may include a plurality of spacer members that extend between adjacent elongated mounts fixedly to retain the elongated mounts in their 5 spaced apart relationship. The spacing arrangement may include a plurality of elongated spacer members that are arranged to form a matrix-like formation, in which the elongated tactile indicator mounts project from nodes of the matrix-like formation. In one embodiment, the spacing arrangement may be generally square 10 in outline when viewed in plan view. Instead, the spacing arrangement may be generally rectangular in outline, or generally triangular in outline, or the like, to suit certain applications. The body may include edge coupling formations for edge-to-edge coupling with another body of another body mounting arrangement. The edge 15 coupling formations may be in the form of complementary dovetail coupling formations or a halving detail formation. The mounting arrangement may include removable plugs for closing the open ends of the tactile indicator mounts, so as to resist ingress of the settable material during casting of the settable material. Alternatively, the 20 mounting arrangement may include a sealed knockout caps. The invention also provides a tactile system, which includes: at least one mounting arrangement for tactile indicators, as defined above; and at least one tactile indicator that is configured for mounting onto the mounting arrangement. 25 The tactile indicator system may include a plurality of mounting arrangements. Each mounting arrangement may include any one or more of the optional features as herein defined, describe, and illustrated. The tactile indicators may be in the form of tactile indicator studs having a head portion and a mounting formation for cooperating with the 30 tactile indicator mounts. Instead, the tactile indicators may be in the form of a directional indicator formed of a plurality of tactile indicators formed as a single elongated head portion with the tactile indicators providing for direction indication.
WO 2013/091027 PCT/AU2012/001607 4 The invention extends to a method for installing tactile indicators, which method includes: positioning a mounting arrangement within a space in which a floor is to be formed with a settable material; and casting the settable material to form the floor so as to secure the mounting arrangement by way of 5 in situ casting. The 'method may include closing open ends of the tactile indicator mounts with plugs or knockout caps prior to casting of the settable material, and subsequently removing the plugs or knockout caps to reveal the open ends of the tactile indicator mounts for mounting the tactile indicators. 10 BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the invention are now described by way of example with reference to the accompanying drawings in which: Figure 1 shows a three-dimensional view from above of a mounting 15 arrangement, in accordance with the invention, for tactile indicators; Figure 2 shows a top plan view of the mounting arrangement in Figure 1; Figure 3 shows a partly sectioned view of the mounting arrangement taken along lines A-A of Figure 1; 20 Figure 4 shows a side elevation view of the mounting arrangement in Figure 1; Figure 5 shows a partly sectioned view of the mounting arrangement in Figure 1, in use; Figure 6 shows another embodiment of a mounting arrangement, in 25 accordance with the invention; and Figure 7 shows a top plan view of the mounting arrangement in Figure 6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 30 In the drawings, reference numeral 10 generally indicates a mounting arrangement, in accordance with the invention, for tactile indicators 16. The mounting arrangement 10 forms part of a tactile system 12 that includes the mounting arrangement 10 and a plurality of tactile indicators 16 that are mounted or mountable on the mounting arrangement 10. The mounting WO 2013/091027 PCT/AU2012/001607 5 arrangement 10 finds particular application for in situ casting in a settable material, such as a settable cementitious material when forming a floor 48, as is explained in more detail below. The mounting arrangement 10 includes a body 18 that is formed from a 5 synthetic plastics material, such as PVC. In this embodiment the body is formed from a PVC compound that resists structural degradation when the body 18 is in situ casted in the settable cementitious material. Moreover, the body 18 is unitary in construction and formed in a plastics molding process. The body 18 includes a plurality of tactile indicator mounts 20 for 10 cooperating with mounting formations 24 of the tactile indicators 16. In this embodiment, each tactile indicator mount 20 is in the form of an elongated circular cylindrical tubular formation defining an axially extending open ended passage 26. The passage 26 can be rebated or screw-threaded to receive and lock the tactile shaft, for example at 27, and shaped and sized for 15 receiving the mounting formation 24 of the tactile indicator 16. It will be appreciated that the tactile indicators and tactile indicator mounts can be formed for mounting by way of an interference fit or locking, a frictional fit, or the like. Each tactile indicator 16 is in the form of a tactical indicator stud having 20 a frusto-conical head portion 22 from which the mounting formation 24 projects axially. In another arrangement the tactile indicators 17 may be in the form of a directional indicator formed of a plurality of tactile indicators formed as a single elongated head portion with the tactile indicators providing for direction indication as shown in figure 3. 25 The body 18 includes a spacing arrangement, generally indicated by reference numeral 25, fixedly to retain the elongated mounts 20 in their spaced apart relationship. The spacing arrangement 25 includes a plurality of spacer members 28 which is in the form of flat bars extending between adjacent elongated mounts 30 20 to fixedly retain the elongated mounts 20 in their spaced apart relationship. The spacer members 28 form a matrix-like formation, and the tactile indicator mounts 20 project from nodes of the matrix-like formation in a juxtaposed arrangement.
WO 2013/091027 PCT/AU2012/001607 6 To this end, the body 18 includes edges 30 that have edge coupling formations 32, 34 for edge-to-edge coupling with another body of another body mounting arrangement. The edge coupling formations 32, 34 is in the form of complementary halving detail or dovetail coupling formations which 5 include male dovetail formations 34 and female dovetail formations 32. Stoppers or plugs (not shown) are provided for the mounting arrangement 10 for closing the open ends of the tactile ind-icator mounts 20 to resist ingress of the settable material during in situ casting. Alternatively a knockout cap can be provided for the mounting arrangement 10 for closing the 10 open ends of the tactile indicator mounts 20 to resist ingress of the settable material during in situ casting. The knockout cap is removed prior to the installation of the tactile indicator 16. Figures 6 and 7 show another embodiment of a mounting arrangement 40, in accordance with the present invention, for mounting a tactile indicator 15 42. The mounting arrangement 40 includes elongated slotted mounts 44 that define slots 46 for receiving blade-like mounting formations 49 of the tactile indicators 42. Referring to Figure 5, in use, when tactile indicators 16 are to be provided on a floor 48 which is to be formed, a user selects a required number 20 of mounting arrangements 10 that corresponds with a floor area that is to be covered with tactile indicators 16. Before the floor 48 is casted, the user couples the mounting arrangements 10 to each other with the coupling formations 32, 34 and positions the coupled mounting arrangements 10 in place. Stoppers, plugs or 25 knockout caps are inserted into or over the open ends of the mounts 20 to resist ingress of the settable material. The floor 48 is then cast and left to set. Thereafter, the plugs or caps are removed, for example during a floor finishing step to reveal the open ends of the mounts 20. 30 The tactile indicator studs 22 are then mounted on the mounting arrangement by inserting the mounting formations 24 into the mounts 20.
WO 2013/091027 PCT/AU2012/001607 7 ADVANTAGES The mounting arrangement 10 advantageously provides a mounting arrangement that is able to be in situ casted when casting a floor. In addition, the mounting arrangement provides a plurality of mounts 20 that are readily 5 spaced apart at required distances from each other, for example readily to correspond with regulated spacing distances for tactile indicators. It follows that by using the tactile system 12 there is no need for drilling or cutting holes into the floor after the floor is formed to mount the tactical indicators, and therefore.has the advantage to save time and cost for installing 10 tactile indicators on a floor that is being formed. VARIATIONS It will be realized that the foregoing has been given by way of illustrative example only and that all other modifications and variations as 15 would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of the invention as herein set forth. Throughout the description and claims of this specification the words "comprise" and variations of that word such as "comprises" and "comprising" are not intended to exclude other additives components integers or steps. 20
