Description

[Detailed Description of the Invention] The present invention relates to the structure of a stair tread, and its purpose is to provide a tread with an anti-slip function on the surface of the tread, and to provide a tread with a novel and excellent appearance.

Conventionally, stair treads have been fitted with non-slip members made of composite or synthetic resin at the nosings to prevent slipping and wear, and in the case of wooden treads, hardwood members with grooves or textured surfaces have been used. Alternatively, JP-A-54-120914 discloses a method in which granules are attached to a thick coating film and a portion thereof is press-fitted into the coating film.

However, when using a tread with a non-slip material attached, the material may suddenly peel off during use, or tripping may result in an unexpected result. Most of them had a linear and monotonous appearance.

Therefore, in the present invention, we considered the above problems and created a transparent or semi-transparent synthetic resin with uneven texture on the upper surface of the convex part in synchronization with the flat pattern previously printed on the nosing of the tread. The problem is solved by providing a stair tread whose raised pattern is formed by a screen printing method.

The details will be explained below with reference to the drawings.

FIG. 1 is a perspective view of a footboard according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof.

1 is a tread, and for normal residential use it is made of sawn boards, laminated wood,
Alternatively, a decorative sheet such as a natural wood board, a vinyl chloride resin sheet, or decorative paper is pasted onto the surface of a substrate such as plywood or particle board.

Reference numeral 2 denotes an uneven transparent or translucent synthetic resin raised pattern printed on the nosing of the step board 1. The shape of the raised pattern 2 is raised in synchronization with the flat pattern 3 of a floral or abstract pattern previously printed on the nose of the step by a method such as ordinary offset or flexo printing.

In order to make the pattern 2 uneven, it is printed using a silk screen printing method using an emulsion-type or solvent-type transparent ink such as a high solid content acrylic resin, epoxy resin, or urethane resin with a non-volatile content of 50% or more. Pound it up to a thickness of ~500μ.

The height of the raised pattern 2 is set within the above range in order to give the pattern three-dimensionality and to take into consideration ink adhesion and durability.

As for the transparency of the ink, the base decorative sheet 7
The upper pattern 3 needs to be transparent or translucent to the extent that it can be seen through the two layers of the raised pattern.

The transparent or translucent raised pattern 2 is formed by the screen printing method by forming small irregularities 4 in the texture of the screen on the upper surface of the convex part of the raised pattern 2, which causes diffused reflection on the surface of the pattern. This is to further add the luster and anti-slip effect of the crystal.

After forming the transparent or translucent uneven raised pattern 2, the surface of the tread plate 1 is coated with a commonly used transparent top coat 5, or an anti-wear agent such as aluminum powder is mixed into the top coat 5. It is also possible to further improve durability.

As described above, the tread of the present invention has an uneven transparent or semi-transparent synthetic resin raised pattern formed on the step nosing to prevent slipping and to improve the design, in synchronization with the previously printed flat pattern. Because of this, the raised pattern not only allows the flat pattern to be seen through from the surface, but also the raised pattern itself becomes a pattern, and the uneven texture of the upper surface of the convex part shines like a crystal, giving it unprecedented safety and appearance. It has the effect of providing a stepping board.
