"Tactile ground surface indicator" Details of Associated Provisional Applications No: 2007903648 filed 5 July 2007; and No. 2007906297 filed 16 November 2007.
The following statement is a full description of this invention, including the best method of performing it known to us: QO\OPER\MRF\2008\NZ 30547474 150 doc 29/5/08 -1A- 00 Tactile 'Ground Surface Indicator The present invention relates to tactile indicators which are disposed on a ground surface to provide a tactile and/or visual indication to a person, particularly a blind or vision- Simpaired person, walking on the surface.
(Ni S 10 Tactile ground surface indicators are specially configured protrusions which are positioned 00oO on walking surfaces. Such indicators are typically found in public areas in and around buildings and stairs, or at pedestrian crossings and the like, to forewarn pedestrians, particularly blind or vision-impaired persons, of an upcoming obstruction or hazard. When the person feels the tactile indicators under their feet, they are made aware that their next step should be taken with caution.
Tactile ground surface indicators can be located, for example, in approaches to steps or stairs, edges of railway platforms, traffic crossings, ramps and so forth.
It is advantageous to machine or mould tactile indicators from stainless steel, because of its strength and durability. Stainless steel indicators are typically adhered to the ground with adhesive such as epoxy adhesive, either directly on the ground surface or in a recess or cavity in the ground into which a stem of the indicator is received. The need for adhesive complicates the installation of the tactile indicators, in that supplies of such adhesive must be maintained and the indicators are vulnerable to dislodgement before the adhesive has set, generally necessitating downtime, usually of the order of 24 hours, during which the area in which the indicators have been installed must be cordoned off.
According to a first aspect of the present invention, there is provided a tactile ground surface indicator, comprising: a body, made of metal and comprising an indicator portion configured to be positioned above a ground surface; and a retaining portion, configured for retaining engagement with the body and being receivable in a cavity provided in the ground, the retaining portion being adapted to deform against a wall of the cavity when the tactile ground surface indicator is inserted into the P:\OPER\MRPSpcifications\2008\30547474 AU I SOdoc 29/5/08 00 0 O cavity to retain the tactile ground surface indicator in the ground.
Deformation of the retaining portion against the wall establishes sufficiently tight contact engagement between the retaining portion and the wall to resist upward pulling forces on the indicator. Such engagement will generally include frictional engagement.
SAdvantageously, the tactile ground surface indicator can thus be installed very rapidly, without any adhesive, whilst still being robust and durable.
00 In one embodiment of the present invention, the retaining portion and body are provided as
O
O a single piece. In accordance with such an embodiment, driving the indicator, and in particular the retaining portion, into the cavity causes the deformation of the retaining portion. The retaining portion may be overmoulded to the body.
In a preferred embodiment of the present invention, the retaining portion and body are instead provided separately and are configured to be retainably coupled. Preferably, the body is configured with a stem which extends downwardly from the indicator portion and the retaining portion comprises an upwardly opening recess arranged for downward receipt of the stem therein. Preferably, the stem is sized such that it urges the retaining portion radially outwardly when inserted into the recess, whereby the retaining portion may be first inserted into the cavity alone, with little or no force, and the stem subsequently driven into the recess to force the retaining portion against the cavity wall to effect the deformation.
Preferably, the stem and a wall of the recess are configured with formations which interlockingly engage when the stem is inserted into the recess. The formations may comprise complementarily configured ribs and grooves which are provided on the stem and the recess wall respectively or vice versa. The ribs and grooves may extend circumferentially.
Preferably, the retaining portion is formed with at least one protuberance which protrudes radially outwardly to deform against the cavity wall.
In one embodiment, the at least one protuberance comprises a pair of opposed ribs which extend in general alignment with the direction of insertion of the retaining portion in the P \OPER\MRFSpecificaLion,2OO8O\547474 AU 50 doc 29/5/08 00 3 recess to engage opposed portions of the cavity wall.
In an alternative preferred embodiment of the present invention, the at least one protuberance extends circumferentially around the retaining portion to engage the opposed S 5 portions. In particular, the at least one protuberance may comprise one or more ribs Cc extending around the retaining portion. The ribs may define a barbed or saw-tooth O configuration which facilitates insertion of the retaining portion.
00 SConsistent with national standard no. AS/NZS 1428, tactile ground surface indicators according to preferred embodiments of the present invention provide areas of raised ground surface texture treatment, designed to provide blind or vision-impaired pedestrians with warning and/or directional orientation information.
According to a second aspect of the present invention, there is provided a method of installing a tactile ground surface indicator, the indicator comprising a retaining portion and a metallic body formed separately from the retaining portion, the body having an indicator portion arranged to be positioned above a ground surface and an anchoring portion extending from the indicator portion, which method comprises: inserting the retaining porltion in a cavity provided in the ground surface; and inserting the anchoring portion into the cavity to effect retaining engagement between the anchoring portion and the retaining portion and to effect deformation of the retaining portion against the wall of cavity such that the retaining portion is retained in the cavity.
According to a third aspect of' the present invention, there is provided a method of manufacturing a tactile ground surface indicator, the method comprising: forming a body from metal, the body having an indicator portion configured to be positioned above a ground surface; and overmoulding a retaining portion on the body such that the retaining portion is locked to the body, the retaining portion being made from a deformable material and being configured to deform against a wall of the cavity when the tactile ground surface indicator is driven into the cavity to retain the tactile ground surface indicator in the ground.
P:\OPER\MRF\Specifications\2008\30547474 AU I 50 doc 295108 00 4 The present invention will now be described, by way of non-limiting example only, with Sreference to the drawings, in which: Figure 1A is a perspective view of a tactile ground surface indicator according to a c 5 first embodiment of the invention; Cc, Figure 1B is a top view of the indicator showing Figure 1A; O Figure lC is a cross-sectional elevation view taken through section J-J in 00 Figure 1 B, showing deformable longitudinal ribs of a retaining portion of the indicator; Figure 1D is a cross-sectional elevation view taken through section K-K in Figure 1 B, showing channels of the retaining portion of the indicator; Figure 2A is a perspective view of the body portion of the tactile ground surface indicator according to both the first embodiment and a second embodiment of the invention; Figure 2B is a top view of the body portion shown in Figure 2A; Figure 2C is a cross-sectional elevation view taken through section D-D in Figure 2B; Figure 2D is a rotated side view of the body portion shown in Figures 2A to 2C.

The indicator 1 further comprises a generally elongate retaining portion 9, which is received over, and engaged with, the stem 7, the retaining portion, which is for holding the indicator 1 in the ground, being made from suitably deformable plastic, whereby the retaining portion comprises a deformable portion, as will be described in further detail later, which is configured to deform against an annular wall of the cavity when the indicator 1 is driven into the cavity.
The retaining portion in this embodiment is moulded as a single piece of plastically-deformable plastic, and is moulded to, the stem 7. The retaining portion 9 is configured as a cap which covers the stem 7, the cap defining a recess 11 which is occupied by the stem 7. The retaining portion 9 has a generally circular outer transverse cross-sectional profile.
The exterior of the retaining portion is provided with a pair of opposed ridges or ribs 13 which extend linearly and longitudinally along the retaining portion 9 from a top end of the retaining portion 9. The ribs 13 are provided at diametrically opposite positions on the retaining portion 9. The ribs 13 protrude radially outwardly to be engageable with the annular wall of the cavity so as to deform against the wall when the indicator 1 is driven into the cavity, thus permanently locking the retaining portion in the cavity and fixing the indicator 1 in the ground. To this end, the outermost extents of the ribs 13 are spaced apart by a distance which slightly exceeds the diameter of the cavity.
P:\OPER\MRF\Specifications\2008\30547474 AU 150.doc 29/5/08 00 6 In an alternative embodiment, two pairs of ribs are provided the ribs of each pair lying at Sdiametrically opposite positions cn the retaining portion to define planes which are perpendicular to each other and which each form an acute angle of 600 with the plane in S 5 which the channels 17 are arranged.
(Ni O The lower end 15 of the retaining portion 9 is tapered radially inwardly to facilitate driving 00 of the indicator 1 into the ground.
The retaining portion 9 further comprises a pair of longitudinally extending channels 17 which are disposed at diametrically opposite positions on the exterior of the retaining portion 9 and extend generally linearly between the top and bottom ends of the retaining portion 9. The channels 17 define: spaces into each some of the material of the retaining portion 9 can be displaced when the retaining portion 9 is driven into the cavity, under a radially inward pressure exerted by the cavity wall, giving rise to a radially outward biasing of the retaining portion against the cavity wall, which assists retention of the indicator 1 in the ground.
An annular channel 19 is provided in the exterior of the stem 7, the channel 19 defining a space into which a complementarily configured, radially inwardly projecting portion 21, in the form of an annular rim, provided on the retaining portion 9 in the recess 11, is received.
The channel 19 defines a transversely extending portion which in turn defines an upper shoulder 23, providing a downwardly facing surface 25. The channel 19 also defines a further transversely extending portion which in turn defines a lower shoulder 27, providing an upwardly facing surface 29.
Similarly, the projecting portion 21 defines, on the retaining portion 9, a transversely extending portion which in turn defines an upper shoulder 30, providing a downwardly facing surface 31. The projecting- portion 21 also defines a further transversely extending portion which in turn defines a lower shoulder 33, providing an upwardly facing surface P.\OPER\MRRSpecifkaions\2008\30S47474 AU 150do 295/08 00 7 The downwardly facing surface on the retaining portion 9 abuts the upwardly facing surface on the stem 7 to restrain the body 3 from upward movement relative to the retaining portion 9. Similarly, abutment of the downwardly facing surface of the stem 7 with the upwardly facing surface of the retaining portion 9 prevents downward movement C' 5 of the body 3 with respect to the retaining portion, as does abutment of the upper end of the Sretaining portion 9 with the underside of the indicator portion 5. Relative movement O between the retaining portion 9 and body 3 is thus prevented.
00 In other embodiments, the abutting surfaces need not face exactly upwardly and downwardly but rather need merely to have respective upwardly and downwardly facing components.
As can be seen in Figures 1C and ID, the recess 11 and stem 7, and particularly the channel 19 projecting portion 21, are complementarily profiled such that the retaining portion 9 is closely received over and fitted to the stem 7.
As will be clear from Figures 1B and 1 D, the channels 17 lie in an upright plane which is perpendicular to an upright plane in which the ribs 13 lie. The ribs 13 are thus provided intermediate the channels 17 around the exterior of the retaining portion 9.
In the following description of the second and third embodiments, the same reference numerals as used in respect of the first embodiment will be used to designate common features.
The indicator 1' according to the second embodiment is shown in Figures 3A to 3C. It is identical to the indicator 1 of first embodiment in every respect except that the retaining portion comprises opposed ridges or ribs 13' which, instead of extending longitudinally along the retaining portion extend around the retaining portion The ribs 13' each extend between the channels 17 and are provided at opposite sides of a longitudinally-extending plane passing through the channels, the ribs 13' thus defining a substantially annular deformable portion. The ribs 13' are provided approximately halfway down the retaining portion.
P OPERV\MRF\Spccifications\2008\30547474 AU 150 doc 29/5/01)8 00 8 In an alternative embodiment, the retaining portion comprises more than two ribs, constituting protruberances or protruding portions, extending therearound to define a substantially annular deformable portion. In another alternative embodiment, the deformable portion is defined by deformable wings protruding from the retaining portion.
A tactile ground surface indicator 1" according to a third embodiment of the invention, as O depicted in Figures 4A to 4C, also comprises a body portion 3 (see Figure 4B) moulded as Sa single piece of stainless steel, or machined from a solid bar of stainless steel. The body portion 3 comprises an indicator portion 5, which is identical to the indicator portions of the first and second embodiments. The body portion 3 further comprises a stem 7 and an elongate retaining portion 9" into which the stem 7 is lockingly receivable.
In this embodiment, the retaining portion instead of being overmoulded to the stem 7, is formed separate from the body 3 and is constructed to receive lockingly the stem 7 during installation in the ground 7, as will be described in greater detail below.
The retaining portion a perspective view of which is shown in Figure 4B, is moulded as a single piece of plastically-defornable plastic. The retaining portion 9" takes the form of a generally cylindrical cap which is receivable over the stem 7, the cap having a recess 11 which is to be occupied by the stern 7.
The exterior of the retaining portion 9" is configured with a plurality of radially outwardly protuberances or protruding portions, in the form of ribs or ridges 13" which are arranged axially or longitudinally along the retaining portion 9" and which each extend therearound.
The ridges 13" provide a serrated longitudinal cross-sectional profile, affording the exterior of the retaining portion 9" a barbed configuration. As can be seen in Figure 4A, each ridge 13" extends upwardly and radially outwardly to define an annular edge 71.
The retaining portion 9" further comprises openings in the form of a pair of axially extending slots 73 disposed on opposite sides of the retaining portion the slots 73 providing communication between the outside of the retaining portion 9" and the recess 11.
The slots 73 are located at approximately the same axial position along the retaining P \OPER\MRF\Specifications\2DO8\30547474 AU 150 doc- 29/5/08 00 9 O9 portion 9" as the ridges 13".
The stem 7 has a lower portion 7A, an upper portion 7B and a tapered step 7C between the upper and lower portions. The diameter of the lower portion 7A is less than that of the recess, whereas the diameter of the upper portion 7B is slightly greater than that of the Cc recess.
00 The inner wall of the recess 7 is; further provided with a plurality of circumferential Sgrooves 75 which lockingly receive circumferential ribs 77 formed on the stem 7, as will be described in further detail below.
Installation of the tactile ground surface indicator 1" according to the third embodiment commences with drilling a cavity into the ground, the cavity having approximately the same diameter and depth as the retaining portion The retaining portion 9" is then inserted into the cavity. Each edge 71, because the ribs extend upwardly and radially outwardly, is a trailing edge when the retaining portion 9" is inserted, whereby any engagement between it and the cavity wall during insertion will not hinder insertion.
Next, the lower end of the stem 7 of the body portion 3, which is tapered to facilitate insertion, is introduced into the open upper end of the retaining portion 9" and forced down through the recess 7, whereby the tapered step 7C and upper portion 7B engage the inner wall of the recess 7 to cause the walls of the retaining portion including the ridges 13", to be displaced radially outwardly such that the tips 71 are forced against the annular wall of the cavity, whereupon the ridges 13" serve as barbs which engage with the annular wall and will resist pulling forces which may otherwise be sufficient to remove the indicator 1" from the ground, thus locking the retaining portion in the cavity. Because the ridges 13" are plastic, they will deform slightly when forced against the annular wall. The radially outward displacement of the ridges 13" is enabled, or at least facilitated, by the slots 73.
Upon insertion of the stem 7 into the recess 11, the ribs 75 are received in the grooves 77.
As can be seen from Figure 4A, the ribs 77 and grooves 75 are complementarily profiled such that the body portion 3 and the retaining portion 9" are locked together, the stem thus P:\OPER\MRFSpcifications\2OO '30547474 AU O150 doc- 29/5/C8 00 anchoring the indicator 1" in the cavity. Since the retaining portion 9" is made out of plastic, the retaining portion 9" is resiliently flexible to a sufficient extent to enable the Sinner wall of the recess 11 to be displaced radially outwardly to allow passage of the ribs 73 past the grooves 75 during insertion of the stem 7, until the stem 7 has been fully 5 inserted, whereupon the grooves 75 align with the appropriate respective ribs 73 and the inner wall contracts slightly so that the ribs 73 are received in the grooves 00 The indicator portion 5 of each of the indicators 1, 1' and 1" according to the first, second and third embodiments, respectively, is illustrated in Figures 5A to 5E. The indicator portion 5, which is provided as a single piece, has a generally circular transverse cross section and comprises a bottom portion 56, defining a downwardly facing surface 58 arranged to abut the ground surface, an upper portion 57 and a sloped or tapered smooth side wall 59, extending upwardly and radially inwardly from the bottom portion 56 to the upper portion 57 and being inclined at an angle of approximately 350 to 450 from the downwardly facing surface 58. The diameter of the bottom portion is 35 millimetres.
The upper portion 57 is defined by an upwardly facing surface 61, which is bounded by an upper end of the side wall. The diameter of the upwardly facing surface 61, and thus the upper portion, is 25 millimetres. The distance between the downwardly facing surface 58 and the upper portion 57 is 4 to 5 millimetres.
A gripping portion, provided by a circular lip 60, is provided at a radially outermost position on the upper surface 61 and extends upwardly from the upper surface 61 to define a shoulder 62 which protrudes outside of the conical plane defined by the side wall 59, i.e.
by extrapolation in the upwardly and radially inwardly direction in which the side wall 59 extends. The shoulder 62 comprises an edge 64 which lies outside of the conical plane.
The lip 60 has a height of 0.5 millimetres The protruding shoulder 62, particularly its edge 64, is able to catch and engage the sole of the person's shoe, particularly as, moved against the tactile ground surface indicator in a direction having a sideways component, thereby preventing slipping, especially in the general plane defined by the side wall, and conferring improved anti-slip characteristics to P \OPER\MRFSpecifications\2008\30547474 AU 15Odoc- 29/5108 00 00 11 the tactile ground surface indicator.
STo enhance gripping further, a gripping pattern 63, is provided on the upper surface 61, the gripping pattern 63 comprising a plurality of concentric rings 65 extending upwardly from S 5 the upper surface 61. The upper ends or tips of the rings, which define the uppermost c extent of the gripping pattern 63, lie in a plane which is approximately 0.5 millimetres O above the upper portion 57, or the plane defined by the upwardly facing surface 61 and are oO coplanar with the top end of the circular lip 60 and the upper edge 64.
The concentric rings 65 each have a thickness of approximately 0.5 millimetres, as does the lip 60. The concentric rings 65 have a radial pitch P of approximately 1.10 millimetres, each ring 65 thus having a thickness which is approximately 45% of the radial pitch P.
Annular spaces 66 are defined between the rings 65, the annular spaces having a radial dimension of approximately 0.6 mllimetres, as does the annular space defined between the lip 60 and the outermost ring Manufacture of the indicator 1 and 1' according to the first and second embodiments firstly comprises moulding of the body portion 3, including the indicator portion 5, from stainless steel, or machining it from a solid billet of stainless steel.
With the body portion 3 arranged upside down, the stem 7 is then centrally positioned in a mould which defines the external configuration of the retaining portion the flat underside of the indicator portion 5 abutting a lower end of the mould to close that lower end. Molten plastic is then injected into the space between the mould and the stem, through a suitable opening provided in the mould. The plastic is then allowed to cool and set, whereupon the finished indicator 1/1' is removed from the mould.
Owing to the aforementioned abutment of surfaces on the retaining portion 9/9' and stem 7, the retaining portion 9/9' is permanently fixed to the stem 7.
