2. Description of the Related Art In a playground of a kindergarten or a nursery school, the ground is leveled and used, or the ground is concretely paved and used. Therefore, the ground level and the playground of concrete pavement are hard and slippery when wet with rain,
A child who is absorbed in playing falls and hits his head, bruises, scratches, or falls, and hits a steel bar or jungle gym installed in the playground or the edge of concrete in the sandbox to cause injury such as a bone fracture. There is a risk that an accident will occur.

Therefore, elastic and soft rubber chip tiles are laid all over the playground to ensure sufficient shock absorption so that the child will not be injured when the child falls over, and the rubber chip tiles are formed so as to be easily permeable to water. , I try not to slip when walking in the rain.

Similarly, the stepped portion of the stairs or terrace is a place where a child may slip and fall accidentally. So that even if an infant slips and falls, to prevent serious injury, stick flat rubber chip tiles to the flat treads (Fumizura) and vertical rises (kake) on the steps of the stairs and terraces, Attach metal fittings as a non-slip material that also serves as a parting material that covers the edge of the rubber chip tile attached to the tread (Fumizura), or of the rubber chip tile attached to the kick from the front end of the rubber chip tile attached to the tread. We are working to install a separate hard resin non-slip to the upper end.

[0005]

However, the installation work of such a rubber chip tile is carried out by sticking flat rubber chip tiles on a flat tread (fumizura) and a vertical rise (kake) respectively, and finally, at the front end of the tread. Since it was necessary to perform work to install a separate slip stopper from the section to the upper end of the kick, it was very troublesome because the work could not be completed once. In addition, even if you attach a rubber chip tile with water permeability to the stairs to make it difficult to slip, since the non-slip material that also serves as a parting material is hard with metal or hard resin, an unexpected fall accident occurs especially in nursery schools and kindergartens. When you hit the stairs, there is a high risk of hitting the stiff corners and injuring yourself.

Further, even if the rubber chip tile itself has water permeability, since the non-slip material also serving as a parting material to be attached to the corner from the tread of the stairs to the kick is made of metal or hard resin, in the case of rain or dirt. By washing with water, these parting materials block the water to slow down the drying, and the rubber chip tiles also take a long time to be dipped in water, resulting in poor durability.

[0007] The inventor of the present invention uses the conventional flat rubber chip tile and the rubber chip tile and a separate non-slip member to perform the above-mentioned work when the non-slip work is performed on the steps of the stairs or terrace of the building or facility. The present invention has been made to solve the inconvenience of taking time and to provide a floor material integrally formed with a stair slip stopper which is safe and durable in use. Therefore, the object of the present invention is to provide an integrated stair slip stopper that can easily and quickly carry out anti-slip construction on the steps of stairs and terraces of buildings and facilities, and is safe and durable in use. Method for manufacturing molded flooring
