[0002]
[Prior art]
The staircase is formed of a stepped portion composed of a horizontal plane and a vertical plane. Conventionally, an anti-slip projection is used for the step portion to prevent a slip accident or a fall accident. Such protrusions are provided at the edge of the horizontal surface of the stepped portion, and the edge of the stepped portion is made higher than the horizontal surface of the stepped portion. By such processing, slipping of the stepped portion can be prevented, and safety during walking on the stairs can be improved.
[0003]
In addition, an example is known in which a non-slip tape is attached to the surface of the protrusion to enhance the anti-slip effect. Such an anti-slip tape has a base material made of polyester, an aluminum wheel or the like, and mineral particles are fixed to the surface of the base material. Such mineral particles can suppress slipping of shoe soles and the like, and can further enhance safety when walking on stairs.
[0004]
Furthermore, an anti-slip mat may be used for the horizontal portion of the stepped portion. The horizontal portion is covered with such a mat to prevent slipping. Such prevention of slipping in the horizontal portion can prevent tripping of the anti-slip protrusion protruding from the horizontal portion.
[0005]
[Problems to be solved by the invention]
The non-slip tape is applied to a base material such as polyester or an aluminum wheel with a resin adhesive, and is attached to a non-slip projection. Such an adhesive does not have sufficient tackiness and cannot maintain adhesive strength, and thus may be peeled off in a short period of time.
[0006]
Further, the anti-slip mat described above is subjected to anti-slip treatment on the back surface thereof so as not to slip on the horizontal part of the step. Such anti-slip treatment is performed by providing rubber protrusions or nets on the back surface of the mat.
