Abstract

(57) [Abstract] [Purpose] An object of the present invention is to enable mass production of Braille tiles for carpets that do not impair the aesthetics and texture of the carpet and that are also excellent in walking. [Structure] A carpet body in which a large number of dot-shaped circular holes or linear strip grooves are formed in a carpet of 300 to 500 mm square in length and width, and on the other hand, a rubber or synthetic resin material is used from the circular holes or strip grooves of the carpet body. And a tile body having protrusions of the same shape protruding by a certain height, wherein the tile body is integrated from the back surface side of the carpet body so that each protrusion protrudes above the tile bristles of the carpet body. To do.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to Braille tiles for carpets.

[0002]

[Prior art]

 As a measure for visually impaired persons in carpet tiles, holes are preliminarily formed in the carpet tiles, and projections made of thermoplastic resin, rubber, or metal are embedded in the holes to fasten them with screws. On the other hand, there is also a method of embedding a Braille tile made of rubber or a heat-plasticized resin of the same size as the carpet tile while appropriately cutting out a necessary portion of the carpet laid on the floor surface.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional technique, the former needs to make holes one by one, which is troublesome in construction. On the other hand, in the latter, it is necessary to cut the appropriate place of the carpet laid on the floor to the size of the Braille tile angle, and although the work is somewhat simplified compared to the former, it is troublesome and it is a different material, rubber. Alternatively, the large size of the tile made of heat-plasticized resin impairs the aesthetic appearance of the carpet, which is not preferable in appearance.

[0004]

[Means for Solving the Invention]

 The present invention is intended to solve the above problems, and is characterized by a carpet body in which a large number of dot-shaped circular holes or linear strip grooves are formed in a carpet having a length and width of 300 to 500 mm square. On the other hand, the tile body is made of rubber or synthetic resin material and has a protrusion of the same shape that projects a certain height from the circular hole or strip groove of the carpet body. It should be integrated so that it protrudes above the bristles of the body. At this time, it is extremely preferable that the circular protrusion is in the shape of a pot, because it does not place much strain on the foot during walking.

[0005]

[Action]

 The soft texture and anti-slip properties of the carpet provide guidance and warning when the visually impaired are walking, without impairing the texture and aesthetics of the carpet, and do not overload the foot of the pedestrian. Exerts an excellent effect in obtaining

[0006]

【Example】

 FIG. 1 shows the product of the present invention, in which A is a plan view and B is a sectional view. Reference numeral 1 is a carpet body having a length and width of 300 to 500 mm square, and a pile 1b having a hair length of about 3.5 mm is planted on a base cloth 1a having a thickness of about 1.5 mm. . Then, the carpet 1 is provided with a large number of through holes 2 into which the projections of the tile plate described below are fitted.

Reference numeral 3 is a tile plate having a length and width of 300 to 500 mm, which is the same as the carpet body 1, and is made of rubber or a thermoplastic resin material, and the carpet is placed on a substrate 3 a having a thickness of about 1.5 mm. A large number of pot-shaped projections 3b to be fitted into the through holes 2 formed in the body 1 are integrally molded. Here, the tile plate 3 including the protrusions is integrally formed of rubber or a thermoplastic resin material.

The height of the pot-shaped projection 3b is about 10 mm, and when it is fitted into the through hole 2 formed in the carpet body 1 from below, the tip of the pile 1b of the carpet body 1 is inserted. It is configured so that it projects by about 5 mm.

The above dimensions in the present invention show a standard example, and different dimensions can be designed as necessary, but the protrusion 3b protrudes from the tip of the pile 1b by at least about 3 mm. To be done.

In the present invention, the carpet body 1 and the tile board 3 are separately formed, and the protrusions 3b of the tile board 3 are pierced through the projections 3b of the carpet body 1 from below the base cloth 1a of the carpet body 1. It is fitted into the hole 2 to be integrated, and the bonding is performed by applying an adhesive on the substrate 3a of the tile board 3 excluding the protrusion 3b or on the back surface side of the base cloth 1a of the carpet body 1 by pressure bonding. Be seen.

The above is an example of the carpet tile in which the pot-shaped projections 3b are scattered, but the same can be applied to the case of the linear projection. FIG. 2 is an explanatory view of this, where A is a plan view and B is a cross-sectional view. At this time, a linear through hole 2'is formed in the carpet body 1 ', and the tile board 3'is formed. A pan-shaped projection 3'b is formed to be fitted into the linear through hole 2 '. In each of the above-mentioned embodiments, making the upper part of the protrusion into a pan-head shape is excellent in that the load (resistance) of the foot during walking is not too much.

In the present invention, the spot-shaped or linear pot-shaped projections are manufactured by an injection molding method, a compression molding method, or the like. In the case of the injection molding method, rubber or a thermoplastic resin material is injected into a prescribed array of points or linear cavities and vulcanized or cured to produce the resin. On the other hand, the carpet body is manufactured by punching out the carpet ground with a sword type having a specified array of dots or lines, and therefore the tile body 1 and the carpet body 3 can be manufactured extremely easily. .

[0013]

[Effect of device]

 Since the present invention is configured as described above, it is easy to mass-produce, and the product has only the projections of dots and lines scattered in the pile bristles, so that the texture and aesthetics of the carpet are impaired. In addition, it is possible to give guidance and warning to visually impaired people with a soft walking feeling that does not burden the gait, and in particular, because the pile hair surrounds the protrusions. It has extremely excellent slip resistance.
