A plurality of surface protrusions 6 having a substantially elongated shape extending perpendicularly to the direction of movement of the user towards an obstacle or dangerous area to be warned are uniformly distributed on one side 2a of the plate-like component 2. These surface protrusions 6 define a number of rows 7 arranged side by side and parallel and aligned one after the other with a constant lateral spacing. This void is designated by the symbol “
B", and the dimensions are preferably in the range of 70 mm to 90 mm.

The form of each surface protrusion 6 has two parallel straight edges 8 extending at right angles to the direction of movement of the user towards an obstacle or dangerous area; They are interconnected by semicircular end portions 9. Symbol "C" in Figure 1
The total length of each surface protrusion 6 indicated by is 95 mm to 115 mm.
It is desirable to set it in the range of mm. The code for each protrusion 6 is “
The width designated "D" is preferably in the range 25 mm to 35 mm, and the ratio between the lateral gap "B" separating the rows 7 and the width "D" of the protrusion is 2.3. It is desirable that there be

As clearly illustrated in FIG. 1, each row of surface protrusions 6 are
They are uniformly distributed according to constant longitudinal spacings marked "E", the spacings having dimensions of 115 mm to 14 mm.
A range of 5 mm is desirable.

Furthermore, the surface protrusions 6 of each row 7 are offset with respect to the surface protrusions 7 belonging to the adjacent row 7 by a dimension corresponding to half of their longitudinal spacing "E".

Each surface protrusion 6 is 2 m from the soil surface 2a of the plate-like component 2.
It has an upper surface 6a located at a height "F" of m to 5 mm. As is clear from FIG. 3, the upper surface 6a of the surface protrusion 6 has two
The plate-like component 2 is
It is connected to the upper surface 2a of. The radius of the arcuate portions 110a, 10b indicated by the symbol "G" in FIG. 3 is preferably in the range of 6 mm to 10 mm.

As is clear from FIG. 2, the height "F" of the surface protrusions 6 belonging to another row 7 is such that the danger area or the warned obstacle, in this case the end side 5a of the platform 5, approaches It is desirable to increase the size gradually.

In a preferred embodiment, the two first rows of protrusions have a height of 3
mm, while the protrusions of subsequent rows have a height of 4 mm. The plate-like component can also be partially or completely colored in a noticeable color to be convenient for people who are not completely blind.

The functional characteristics of the warning structure according to the invention described above primarily as a structure can be easily understood.

Due to the presence of the surface protrusions 6, the plate-like component is provided with a surface morphology that can be immediately recognized by a blind person by contacting the warning structure 1 when walking towards an obstacle or a warned area.

The elongated shape and orientation of the surface protrusions 6 is also advantageous in informing the blind person of the location and arrangement of obstacles or warned dangerous areas. More specifically, a blind person can know in advance that if he walks in a direction perpendicular to the direction of the surface protrusion 6, he will reach an obstacle or a warned area.

By varying the height of the surface protrusions 6 in steps, the blind person is forced to gradually move closer to the warned area or away from the <;r+ area while intersecting the warned structure 1. I can let you know what's going on.

The present invention achieves the intended objectives.

It will be appreciated that the warning structure of the present invention provides clear and easily recognizable information to alert a blind person to the presence of an obstacle or dangerous situation.

In this regard, due to the characteristics of the given structures and the above-mentioned dimensional ratios of the structures, a blind person can immediately recognize the presence of structures with which he comes in contact while walking on the floor 3.

Furthermore, it must be pointed out that the warning structure of the invention can be manufactured at extremely low cost and can therefore be easily installed even on existing footpaths.

Although the warning structure of the present invention is specifically constructed for use by people who are blind or have a significant visual impairment, the structure does not pose any inconvenience to the general public in the area in which it is installed. It will be understood that this is not the case.
