Abstract

[PROBLEMS] Based on the “Law on Promotion of Smooth Movement Using Public Transportation for Elderly People, Physically Handicapped Persons” (commonly known as “Transport Barrier Free Law”) promulgated on May 17, 2000 According to the “Guidelines for the Improvement of Road Movement Smoothness”, the visually impaired person guidance block has a luminance ratio of about 2 with the surrounding road surface (block). Blocks around the block are limited to low-brightness colors such as black, red, and brown.
A visually impaired person guide block is formed around a visually impaired person guide block by forming a low-luminance hue line having a width of about 20 mm in parallel with a linear protrusion on both ends of the visually impaired person guide block. A block for guiding visually handicapped persons capable of laying a block having high brightness equivalent to the block.

Description

  The present invention relates to a luminance ratio of a visually impaired person guidance block.

  According to the “Guidelines for the Promotion of Road Movement Smoothing”, conventional blocks for visually impaired persons are basically yellow, and many of the commercially available blocks are yellow.

The brightness of the yellow pavement differs slightly depending on the manufacturer, but it is about 110 cd / m ^{2 to} 130 cd / m ² , and when it is laid next to a high white block with a high luminance, a low luminance ratio (of the visually impaired guide block) Brightness ÷ brightness of paved road surface).

“Movement of the road” based on the “Law on Promotion of Facilitation of Movement Using Public Transportation for Elderly People, Physically Handicapped Persons” (commonly known as “Transportation Barrier-Free Law”) promulgated on May 17, 2000 According to the “Smoothing Maintenance Guidelines”, the visually impaired person guidance block has a luminance ratio of about 2 with the surrounding road surface (block), and in order to secure a luminance ratio of about 2 around the visually impaired person guidance block the block, blackish, brightness etc. reddish or brown is limited to the color low as ^{50cd / m 2 ~60cd / m 2} .

For this reason, after the enforcement of the barrier-free method, it is difficult to combine with a light-colored block whose luminance exceeds 70 cd / m ² or a white block having a luminance equivalent to yellow.

  In other words, on pavement surfaces that require laying blocks for visually impaired persons, the production of regional characteristics by the color of high-pavement materials and the laying of low-cost concrete flat blocks with high luminance will be implemented after the barrier-free law is enforced. It became difficult.

  The present invention makes it possible for the visually impaired person's guide block to stand up even if a block having a high luminance is laid around the visually impaired person's guide block.

  According to the “Guidelines for the Improvement of Road Movement Smoothing”, the guide block for visually handicapped persons has four or more linear protrusions according to the JIS standard, and the interval between the linear protrusions is 75 mm. The width of the bottom side of the protrusion is set to 27 mm.

  According to this, in the 300 mm square block, the linear projections are within 75 mm × 3 + 27 mm = 252 mm. All visually impaired blocks for guiding visually impaired people are made in conformity with JIS standards, so a 300 mm square block has a margin of 24 mm ((300 mm−252 mm) ÷ 2) on the left and right.

In the present invention, a line with a hue of approximately 60 cd / m ² or less, which is a luminance of 1/2 or less of the surface luminance of the guidance block main body for the visually impaired, is provided in the margin. Yellow between the projections in the shape of a projection) and a luminance ratio of 1.5 or more is ensured.

  As a result, the visually impaired person guide block stands up even if a block with high brightness is laid around the visually impaired person guide block.

  With such a device, it is possible to lay a block of high-luminance hue around the visually impaired person guidance block.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  A low-luminance hue line 2 having a width of about 20 mm is formed at both ends of the visually impaired person guiding block 1 in parallel with the linear protrusions 3.

  As a result, a block capable of laying a block having a high hue around the visually impaired person guiding block 1 is formed.

FIG. 1 is an overall view of the present invention.

Claims (1)

  At both ends of the visually-impaired person guidance block, a line with low brightness is applied, and the brightness ratio between the color of the visually-impaired person guidance block itself and the color of the line at both ends thereof is 1.5 or more. A block for guiding visually impaired persons.
