Description

[Detailed description of the invention] The invention is composed of multiple materials such as a core material made of a lumber core or a laminated board, a lauan veneer attached to the core material, and a decorative veneer to decorate the top surface. Related to improvement of decorative treads for stairs.

As shown in FIG. 5, conventional decorative stair treads are made by cross-pasting lauan veneers 4a and 4b on both sides of a core material 1 so that their fiber directions are perpendicular to the fiber direction of the core material 1. Since the thick decorative material 2 was glued to the end face, which is the base, and the decorative veneer 5 was glued to the top surface, anti-slip grooves were formed on the decorative veneer 5 to ensure safety when going up and down. If the run veneer 4a or the core material 1 is carved in the bottom of the groove, the run veneer 4a or the core material 1 is exposed at the bottom of the groove, resulting in a problem that the appearance is unsatisfactory.

The present invention was proposed in order to solve the above-mentioned problems, and its purpose is to provide a decorative tread for stairs provided with anti-slip grooves without impairing the aesthetic appearance.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIGS. 1 and 2 show the decorative tread for stairs according to the present invention, and FIG. 3 shows the tread constituent members. In the figure, 1 is a core material, which is made of lumber core, laminated wood, or the like. 2 is a thick decorative material adhered to the end face of the core material 1 on the facing side, and for example, precious wood such as pine, oak, zelkova, etc. is used. The core material 1 to which the decorative material 2 is adhered is made by adhering the decorative material 2 to a stack of multiple boards 1a and cutting it into a width l corresponding to the wall thickness l of the core material 1, as shown in FIG. Each can be easily obtained by doing the following. These core material 1 and decorative material 2
is bonded with the fiber direction facing the width direction of the step plate. 3a and 3b are base decorative veneers made of precious wood that is the same as or similar in appearance to the decorative material 2, and the fiber direction of the veneers 3a and 3b is parallel to the fiber direction of the core material 1 and the decorative material 2. The decorative material 2 is bonded to both upper and lower surfaces of the decorative material 2 and to a portion near the front end surface of the core material 1 that is connected thereto. 4a and 4b are base decorative veneer 3
It is a lauan veneer glued to both the top and bottom of the core material 1 part excluding the adhesive parts a and 3b, and each lauan veneer 4
The fiber directions of a and 4b are perpendicular to the fiber direction of the core material 1 (so-called cross pasting). 5 is a decorative veneer adhered to the upper surface of the base decorative veneer 3a and the lauan veneer 4a, and is made of the same precious wood as the base decorative veneer 3a. Reference numeral 6 denotes an anti-slip groove formed by carving a long groove in the decorative veneer 5 that overlaps with the base decorative veneer 3a, and the base decorative veneer 3a is visible on the bottom surface of the groove 6. The base decorative veneers 3a, 3b and the lauan veneers 4a, 4b may be adhered to the core material 1 separately, but as shown in FIG. , 3b and 4b are preferably temporarily attached.

In the above embodiment, the base decorative veneer 3b and the lauan veneer 4b are also pasted on the lower surface of the core material 1 in order to decorate the facings of the tiers and to prevent the core material 1 from warping. However, it is also possible to omit these 3b and 4b. In addition, the treads in the above embodiment are suitable for so-called box-type stairs, and the left and right ends are covered by girders on both sides of the staircase, and most of the back side is also hidden by the risers. , these parts are not decorated, but depending on the application, for example, in the case of strip stairs, the back side,
It goes without saying that both ends and the rear end of the wood are also decorated as appropriate. Although not shown, the anti-slip groove 6 may be formed by press-fitting the decorative veneer 5 and recessing it into a groove shape.

In the decorative stair tread of the present invention having the above structure, a lauan veneer is attached to the core material, a base decorative veneer is attached to the front end surface of the core material, and the top surface of the decorative veneer is attached to the core material. Because the decorative veneer is pasted, the lauan veneer is not exposed to the surface, and even if the anti-slip groove is formed by carving it into the decorative veneer, the base decorative veneer will not be exposed at the bottom of the groove. Therefore, the lauan veneer is not exposed. Therefore, even though the anti-slip grooves are formed, a beautiful appearance as if it were made of a single plate can be obtained.
