Embodiment 1

[0020] Such as Figure 1-2 As shown, a strip-shaped direction guide brick includes a brick body 1, and four strip-shaped grooves 2 arranged side by side at equal distances are arranged in the brick body 1. The bottoms of the four strip-shaped grooves 2 are all communicated through vent holes 3, and the vent holes 3 There is a whistle tube 4 inside, and the whistle tube 4 is located between the two bar-shaped grooves 2 in the middle. The bar-shaped groove 2 is sealed and slidably connected with a guiding protrusion 5 through a limit mechanism. When a blind person steps on the middle two bars of the brick body 1 When the leading raised block 5 is on, the whistle tube 4 does not make a sound. When a blind person steps on two or one guiding raised block 5 on one side of the brick body 1, the whistle pipe 4 emits a short alarm whistle to remind the blind person to correct the route in time , to prevent blind people from shifting blind roads to cause dangerous accidents.

Embodiment 2

[0024] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the volume of the two strip grooves 2 located in the middle is smaller than the volume of the two strip grooves 2 located on both sides, when the two strip grooves 2 on one side of the brick body 1 When the guide bumps 5 are stepped on at the same time, the guide bumps 5 close to the center of the brick body 1 first reach the bottom of the strip groove 2, and the air holes 3 are closed, and the guide bumps 5 at the center of the brick body 1 Unable to continue descending.

[0025] When the blind walks on the blind road, a sole of the blind person can step on two of them on the two leading raised blocks 5 in the brick body 1, and when the blind stepped on the two leading raised blocks 5 of B and C, the sentinel tube 4 will not vocalize;

[0026] When the blind person steps on C (or B) and D (or A) two guideway raised blocks 5, C (or B) guideway raised piece 5 moves down to the bo...

Abstract

The invention belongs to the field of guiding devices for the blind, and in particular relates to a strip-shaped direction guide brick, which includes a brick body. The brick body is provided with four strip-shaped grooves arranged side by side at equal distances. The bottoms of the four strip-shaped grooves are all passed through The air hole is connected, and a whistle tube is arranged in the ventilation hole, and the whistle tube is located between the two bar-shaped grooves in the middle, and a guiding lug block is sealed and slidably connected in the strip-shaped groove through a limit mechanism, and the guiding lug lug The upper end of the block extends out of the upper surface of the brick body. The present invention can make the blind person feel undulating feeling when stepping on the guiding raised block, and the tactile feeling is relatively obvious, which plays a good role in guiding the way. Offset, when the blind person deviates too much from the blind path, the whistle will emit a longer alarm whistle to warn the blind person that the route is excessively deviated, reminding him to correct the route in time, so that the blind person can distinguish the degree of deviation from the blind path, and the safety is higher.

Description

technical field [0001] The invention belongs to the technical field of road bricks, in particular to a strip-shaped direction leading road brick. Background technique [0002] Guide bricks are convenient road facilities for blind people to travel safely. Generally, it is paved with three types of bricks, one is strip-shaped guiding bricks to guide blind people to move forward with confidence; the other is reminder bricks with dots to remind blind people that there are obstacles ahead; the other is blind road danger warning guiding bricks, The dots are larger. [0003] The existing bar-shaped direction leading bricks have a simple structure and can only play a simple guiding role. When a blind person is walking, the route will inevitably have a slight deviation, but the blind person cannot perceive it at this time. This slight deviation will cause a large deviation during the accumulation process of a long road section, so that the blind person deviates from the blind road....
