Abstract

Abstract The present invention is a manufacturing and colouring method for a tactile marker which creates a tactile marker with skid-proof properties. In the process of molding, this is accomplished by creating a wide and annular groove or an uneven surface with natural textures or irregular patterns on the marker surface. This can be done by engraving, or by using three-dimensional precision casting molds to create fine texture or coarse pattern on the marker surface. The texture or pattern is to cover the entire marker surface in order to create a skid-proof effect. Then, the marker surface will be coloured with methods including electrophoresis, electroplating, electrolysis, and baked painting. The entire marker surface, including the uneven surfaces, will be coloured. After colouring, the outermost layer of the marker surface of the tactile marker will be removed by polishing and buffing. With the colour of the outermost layer of the marker surface removed, the colour of the indented surfaces will be retained. Thus the colour contrasted with the surrounding floor and environment of the tactile marker is not too disruptive. T-T- 1 - A '1 -7- A A -O A Figure 3 9 1 3 2 3 2 Figure 4

Description

[0001] The invention is related to the field of tactile markers, especially the manufacturing and colouring method of tactile markers.
Background [0002] Considering the diversity of citizens, there have been more and more concerns to lower the risk for wheelchair users, pedestrians slipping, and pedestrians stumbling. Therefore, it is necessary to balance the demands and opinions between the visually impaired and the general public on the related regulations. Common tactile markers are trapeziumshaped with a flat surface; as for metal tactile markers, the round bevelled edges are polished to a smooth surface which entails a risk of pedestrians slipping.
[0003] Regarding colour contrast, metal tactile markers usually use coloured plastic chips or coloured non-slip stickers. A black or yellow colour is usually used. Although this complies with the regulations, when the colour contrast is too strong or when the colour is concentrated on the top of the marker or the bevelled side of the marker, especially when located indoors, it may disrupt the surrounding environment and interior design. But, the strong colour contrast may not compromise the general aesthetic value for some citizens. Electroplating is a common colouring method. But this makes a single-coloured tactile marker without colour contrast. Furthermore, the colouring may fall off over time with pedestrians trampling it coupled with all other kinds of collisions.
Summary [0004] This invention aims to provide a tactile marker which not only reduces the risk of stumbling or slipping pedestrians, but is also easily visible for the visually-imp aired with suitable colour contrast, as well as consideration for a balanced colouring and aesthetic design value.
[0005] This invention can be actualized by creating a wide and annular groove, or uneven pattern and texture in a round arc or streamline shape that covers the entire marker surface by
DOC ID-1924379744-2204
2019204029 07 Jun 2019 the method of casting. The marker surface will then be coloured. Then, the outermost layer of colouring will be removed, while the colouring in indented areas will be retained.
[0006] Further, a wide annular groove will be worked into the casting mold in a place corresponding to the marker surface. The groove has a round or flat bottom, which leads to the lip surrounding the groove to contain a sharp rounded edge near the top. The sharp edges of the outer and inner circle give a strong skid-proof effect. The distance between the two circles creates a non-slip effect similar to that of a stair nosing or non-slip stair tread.
[0007] Further, natural textures or irregular patterns will be created by casting mold in places corresponding to the marker surface and methods including engraving or threedimensional precision casting mold to create fine or coarse patterns on the marker surface. These textures or patterns will cover the entire exposed surface of the marker so that the entire surface is slip resistant.
[0008] Further, the marker surface is coloured with any one of the following methods, namely electrophoresis, electroplating, electrolysis, baked painting, paint spraying, paint marker. The entire surface or the indented areas of the marker are to be coloured. The colouring materials attach to the marker surface in a high quality and long-lasting manner.
[0009] Further, after colouring, the outermost layer of colouring will be removed with methods including polishing, buffing, blade scraping, or wiping. The colour in indented areas will then be retained, in order to increase the colour contrast of the marker.
[0010] Further, the tactile marker is in the form of a circular shape or a long horizontal strip. The shape of this tactile marker from a schematic view can be a trapezium, round arc, streamlined shape, trapezoid with round corner, or truncated dome.
[0011] Further, the bottom of the tactile marker extends downwards to form a nail, or a small circular protrusion extending from the bottom of the tactile marker, which is for fixing the marker to the mounting target surface. Or, there is a screw hole and a cover in the centre of the marker by using screw to fix the marker to the mounting target surface.
DOC ID-1924379744-2204
2019204029 07 Jun 2019 [0012] Further, the marker is made of metal and the type of metal includes stainless steel, brass or a compound of different metals. If the marker is made of resin, thermoplastic polyurethane is preferred.

Detailed Description [0032] This invention is a tactile marker where the uneven surface with natural texture or irregular pattern is first created by method of casting. The tactile marker will be coloured, then, the outermost layer of the colouring will be removed, and the colouring in the indented areas will be retained. Below is a further description of this invention with examples.
DOC ID-1924379744-2204
2019204029 07 Jun 2019 [0033] As shown in the figure 1(A), a wide annular groove 1 will be worked into the casting mold in a place corresponding to the marker surface. The groove 1 has a round or flat bottom, which creates sharp rounded edge 9, as shown in figure 4(A). The sharp edges 9 of the outer and inner circle give a strong skid-proof effect.
[0034] As shown in the figure 1(B, C), an uneven surface with natural texture or irregular pattern will be created by casting the mold in a place corresponding to the marker surface. Methods including engraving or three-dimensional precision casting mold to create fine or coarse pattern on the marker surface. These irregular textures or patterns will cover the entire exposed surface of the marker so that the entire surface is slip resistant.
[0035] As shown in the figure 2(A, B, C), the marker surface is coloured with any one of the following methods, namely electrophoresis, electroplating, electrolysis, baked painting, paint spraying, paint marker. The entire marker surface or the indented areas are to be coloured. The colouring materials attach to the marker surface in a good and long-lasting manner.
[0036] As shown in the figure 3(A, B, C), after colouring, the outermost layer 3 of colouring will be removed with methods including polishing, buffing, blade scraping, and wiping. The colour in indented area 1 and 2 will then be retained, in order to accentuate the colour contrast of the marker itself. Yellow or black colour is preferred. As the outermost layer 3 of colouring is removed, the part which most easily falls off is removed.
[0037] This invention adopts a special colouring method in order to achieve a colour contrast so that the visually impaired can easily notice the markers on the ground. The colour contrast is not too stark, and does not concentrate only on the top of the marker or the bevelled edge of the marker, but is spread out thoroughly or alternatively, so that they pose little disruption to the ground surface and the characteristics of the surrounding materials and designs. Furthermore, as the tactile marker itself already shows sufficient colour contrasts, it already satisfies the colour contrast standards upon installation on the ground.
[0038] As shown in figure 4(A, B, C), the shape of this tactile marker from a schematic view can be a trapezium, round arc, streamlined shape, trapezoid with round corner, or truncated dome. The colour contrast of the present invention does not rely on coloured sandpaper tape or plastic chips applied on the flat surface on top of the marker. Therefore, the top of the
DOC ID-1924379744-2204
2019204029 07 Jun 2019 marker need not be flat, but can be a round arc or a streamlined surface, so that the engraved fine texture as shown in figure 4(B) or the casted coarse pattern as shown in figure 4(C) can flow and extend to the surroundings more naturally. In addition, the arc surface can reflect light more evenly, resulting in a more even and more thorough colour contrast. This leads to a higher efficiency in terms of both appearance and colour contrast, as shown in figure 6.
[0039] The tactile marker with the wide annular groove is a trapezium when seen from the side view. To prevent pedestrians from stumbling and troubles that wheelchair users typically face, the annular grooves can be situated on the top of the marker near the bevelled edge 4, smoothing out the circular angle on top, so that the side view becomes more streamlined as shown in figure 7.
[0040] The tactile marker is in the form of a circular shape or a long horizontal strip. The elongated strip marker after colouring and polishing is shown in 5A, 5B, and 5C.
[0041] If fixing the marker to the mounting target surface requires drilling , the bottom of the tactile marker extends downwards to form nail 5 as shown in figure 7; If it requires the need to make groove on the floor surface, the bottom of the tactile marker extends downwards to form a small circular protrusion 6 as shown in figure 8; Or, if there is screw hole 7 and cover 8 in the centre of the marker by using screw to fix the marker to the mounting target surface as shown in figure 9.
[0042] The tactile marker is made of metal where the type of metal includes stainless steel, brass or a compound of different metals. If the marker contains resin, thermoplastic polyurethane is preferred.
[0043] It is obvious that the present invention is not limited to the above examples, and the present invention can be modified in various ways. Although the present invention has been discussed in detail in connection with the above examples, it should be understood that some similarities and alternatives that may be apparent to those skilled in the art are within the scope of protection defined by the present invention.
