Hereinafter, a method of manufacturing an electromagnetic induction block for the blind according to the present invention will be described.

The method of manufacturing an electromagnetic induction block for the blind according to the present invention may be manufactured by mixing or inserting an electromagnetic signal generator into a molded body of the block, or may be manufactured by attaching a magnetic body to the surface of the molded body of the block. It can also be produced by attaching magnetic tape to the surface of the flooring material inside and outside.

Referring to FIGS. 3 to 6, 8, and 9, in the method of providing magnetism to these induction blocks, a molded body may be formed by embedding a magnet, attaching a magnetic tape, or mixing ferrite in a mixing step of ceramic raw materials or cement. After fabrication, the signal can be input by magnetizing the entire block or partially.

In addition, in the case of coating or attaching a material capable of inputting a signal to the surface of the block molding agent, the process may be much simpler. In this case, durability of the skin adhesive should be considered. Even if it is installed, it can manufacture blocks that are durable, solid and have a beautiful surface.

Referring to FIG. 7, as an example of a block for inputting a signal by inserting a magnet as described above, the protrusion 44 and the protrusion 42 may be formed in the mold to facilitate the insertion of the magnet, and the inserted magnet M ) Is preferably as far forward as possible without harming the durability of the front of the block, because it is advantageous to read the input signal. In addition, the shape of the magnet (M) can be free, and it is preferable to use an annular magnet, because it can form a uniform and wide magnetic field in the range of the magnetic field.

After the magnet (M) is inserted, the extra space around the remaining projections can be filled with the flooring material, in this case, the inserted magnet is prevented from being separated, especially in the rough or rough roads cement , The silicon can be used to completely fix the inserted magnet. And, when inserting the magnet (M) can be filled with other materials to paste the pin extra space to the floor.

In addition, when cement is used as the binder 22 as the material for forming the block, the cost is significantly reduced, although the appearance is lower than that of the ceramic raw material. When the magnet (M) is inserted, it is possible to physically insert the magnet before the hydration reaction of the cement is developed without making a special head-shaped protrusion in the mold, in which case the magnet 2 No secondary process is needed. In addition, even when ferrite is mixed with cement and magnetized, no change in ferrite properties occurs because a process such as sintering is not necessary. In addition, various materials may be used as a material for forming a molded article of a block.

The present invention is not limited to the above materials but includes all general rubber-based materials, tile materials, ceramic materials and the like. In particular, when rubber-based materials are used, impact resistance and good shock absorption are not obtained when ceramic materials or ceramic materials are used.

FIG. 10 shows the shape of a block for inputting a signal by inserting a conductor ML after molding the block from the above materials. In this case, the intensity of the signal can be adjusted at will compared to the case of inputting the signal using ferrite, magnet, etc., and the signal can be changed at will after the construction of the block, and the signal transmission is much more than using ferrite, magnet, etc. Clearly it has the advantage of no noise in the signal transfer phase. (However, in this case, there is a disadvantage in that the maintenance and maintenance costs are required because of the difficulties in construction and the continuous dependence on the external power supply after construction.)

In addition, the electromagnetic signal generator provides an electric signal or a magnetic signal, and the electromagnetic signal generator is selected from a ferrite, a magnet, a conductor, and an oscillator. When the electromagnetic signal generator is formed of a magnetic material that provides a magnetic signal, the magnetic pattern of the magnetic material may be formed in various forms of a straight line or a non-linear shape, and various information may be provided to the visually impaired person holding a wand capable of detecting the electromagnetic signal. It can provide.

As described above, in the present invention, an electromagnetic induction block for the visually impaired is manufactured to generate an electromagnetic signal in the molded body of the block, and the visually impaired person recognizes a variety of information more accurately by using a wand capable of detecting the electromagnetic signal. You can be guided stably.

According to the present invention as described above, in the implementation of a wide range of materials, such as ceramic materials, ceramic materials, cement, rubber-based materials for the visually impaired can select the appropriate material according to the situation to maximize the characteristics, magnet By inserting or mixing ferrite, conductor, material of radio wave generation part, etc. to input specific signal or by attaching or coating these materials to block molded body to input signal, the visually impaired can reduce the risk factor when walking, There is a special effect that can provide.

In addition, the effect of the present invention can further expand the area that can provide convenience for the walk of the visually impaired by installing a magnetic tape having the function of the electromagnetic induction block in the room space difficult to install due to construction and work problems. .

The above description is only a description of one embodiment of the present invention, the present invention is capable of various changes and modifications within the scope of the configuration.
