Description

Pedestrian guidance urethane block {URETHANE BLOCK FOR PEDESTRIAN GUIDE}

The present invention relates to a pedestrian guide urethane block, and more specifically, a pedestrian guide configured to prevent pedestrians from walking safely by allowing the pedestrian to more accurately recognize the direction of the walkway and its surroundings. It relates to a urethane block.

In general, the conventional pedestrian guide block 10 is installed in a platform using an underground train or a train to guide the visually impaired to walk or board a train, as shown in Figure 1a and 1b of the plate-shaped plate ( 11) A circular or bar-shaped display unit 12 is formed to protrude from the upper end, and the visually impaired person recognizes the shape of the display unit 12 formed at the upper end of the plate 11 as the sole to move forward or turn left or right. By stopping or stopping, the blind person can walk in the desired direction or get on the train at the platform.

However, such a conventional walk guide block 10 is formed by the most paint is formed on the surface after being molded of concrete, or the display portion 12 for recognizing the walking information is molded of a plate formed of stainless steel ( 11) Because it is combined with the upper surface, it is broken even with a small impact, and the paint is peeled off after a long time, and the appearance is not good, and when the display unit 12 is made of stainless steel, shoes are worn with rain water due to the characteristics of smooth stainless steel. When stepped on (12), the shoe slipped on the display unit 12, causing the pedestrian to lose its center, thereby causing a safety accident.

In addition, the conventional walking guide block 10 is formed of concrete or stainless steel, so it is easy to recognize the direction of walking by stepping on the visually impaired foot, but in a dark place, for example, if there is no light or there is a light underpass or road In the case of a general pedestrian walking by recognizing a direction visually at a place such as a sidewalk or a stairway, there is a problem that the walking guide block 10 has difficulty in walking because the walking guide block 10 is not identified.

The present invention has been proposed in view of the problems described above, and its purpose is to allow the visually impaired to step on the soles of the foot and recognize the walking information, and to walk in the desired direction as well as to clearly identify the walking person during the day or night. The purpose of the present invention is to provide a walking guide urethane block configured to make walking safer by making the direction and surrounding conditions more accurate.

According to a feature of the present invention for achieving the above object, in the block formed by successively projecting the display portion on the upper surface of the plate, the block is absorbed by shock and at the same time, characterized in that molded with urethane having a fluorescence and luminous function Guided urethane blocks are provided.

As shown in 3c, in a block in which the display portion 120, such as a mountain shape, is protruded in succession, the block is formed of urethane having excellent shock absorption.

In some cases, an adhesive layer 130 may be formed on the bottom of the plate 110, and a release paper 140 may be attached to the bottom of the adhesive layer 130.

The urethane, which is a material of the walking guide urethane block 100, is made of a prepolymer and a curing agent, and its blending ratio varies slightly depending on hardness, but has a blending ratio as shown in Table 1 below. That is, when a prepolymer is 86.7 weight%-87.6 weight%, a hardening | curing agent is mix | blended in the ratio of 12.4 weight%-13.3 weight%.

Raw material Compounding ratio (% by weight) Prepolymer 86.7-87.6 Hardener 12.4 to 13.3

In some cases, the prepolymer and the curing agent are mixed with urethane, which is a material of the guiding urethane block 100, to have fluorescence and photoluminescence functions. After accumulating the fluorescent pigment and the incident light, a mixed pigment in which a photoluminescent pigment that emits light for a predetermined time according to the amount of incident light is added at a predetermined ratio may be added. As shown in the figure, when the prepolymer is 82.5% by weight to 83.8% by weight, the curing agent is 11.8% by weight to 12.8% by weight, and the mixed pigment is formulated in a ratio of 4.1% by weight to 5.3% by weight.

Raw material Compounding ratio (% by weight) Prepolymer 82.5-83.8 Hardener 11.8-12.8 Mixed Pigment 4.1-5.3

The mixed pigment is HBr, NaBr, TiO ₂ , CoO, FeO ₃ , NaHS0 ₃ , ZnO ₂ , KMn0 ₄ , 2H ₂ 0, MnCl ₂ 4H ₂ 0, Sb ₂ O ₃ , TiCl ₄ , (NH ₄ ) Mo ₇ 0 ₄ 4H ₂ 0 In order to display the desired color of the inorganic material, such as the above inorganic material is optionally mixed and used, the fluorescent pigment is a diazomethane (diazomethane: C ₆ H ₅ including the azo group and the blended inorganic material) N = NC ₆ H ₅ ) as well as the diazomethane contains some aromatic compound anthraquinone (anthraquinone: C ₁₄ H ₈ 0 ₃ ), and the photoluminescent pigment is a little diazomethane to the anthraquinone. It is composed.

As shown in Table 3 below, the mixing ratio of the plasticizer having the above characteristics and the fluorescent pigment and the phosphorescent pigment is 8.9% by weight to 10.8% by weight when the plasticizer is 89.2% by weight to 90.9% by weight. Consist of a proportion of

Raw material Compounding ratio (% by weight) Plasticizer 89.2-90.9 Fluorescent Pigment 8.9 to 10.8

In addition, the urethane, which is the material of the walking guide urethane block 100, is selected from any one of a variety of prepolymers classified by strength or bonding structure according to the application to be applied, and the selected prepolymer of the curing agent and pigment mixed The compounding ratio may be configured to be slightly increased or decreased, and the compounding ratio of the plasticizer and the fluorescent pigment and the photoluminescent pigment forming the mixed pigment may also be configured to be slightly increased or decreased.

The walk guide urethane block 100 according to the present invention configured as described above is molded in urethane so that it is not easily broken or deformed even when an impact is applied, and it is not slippery, so that the visually impaired person steps on the display unit 120 more safely. It can be recognized.

In addition, the walk guide urethane block 100 of the present invention is formed of a urethane having a fluorescence and luminous function, when installed in the basement of the underpass or stairway road, etc. not only emits light during the day but also accumulated at night without light As the light is emitted, it has a clear discrimination ability during the day and at night, so that ordinary pedestrians can accurately recognize the direction of the walkway and the surrounding situation so that they can walk more safely.

In addition, the walk guide urethane block 100 according to the present invention is to remove the release paper 140 from the adhesive layer 130, and then attach the adhesive layer 130 to the desired location, for example, the base surface, such as the basement, stairs or roads around the road. By being fixed by the installation of the walk guide urethane block 100 can be more easily installed.

As described above, the pedestrian guide urethane block, which is formed of urethane having fluorescence and luminous function, enables the visually impaired person to walk in the desired direction by recognizing the walking information by stepping on the sole, as well as general pedestrians during the day or night. It is effective to make walking safer by clearly identifying the walking direction so that the walking direction and its surroundings can be recognized more accurately.
