Description

[Detailed description of the invention] The present invention relates to a staircase with a new configuration, and its purpose is to integrate the decorative surface board of the tread and the riser board, so that it has a beautiful appearance and does not cause treading. Our aim is to provide stairs to a wide range of people.

As shown in Figure 1, the conventional staircase has a holder on the top of the board,
Attach a decorative veneer made of wood veneer, vinyl chloride resin sheet, printing paper, etc. to the front edge of the front and bottom parts, and
The receiver is provided with a groove C on the lower surface of the plate A, a groove C is carved along the length of the plate A to form a tread E, and the upper end of the riser plate E is fitted into the groove C, The lower end was placed on the surface of the adjacent footboard for admonition.

However, because conventional stairs are constructed as described above, there is no continuity between the surface pattern of the decorative veneer entrance and the surface pattern of the second riser board, which is attached to the board with adhesive. It was extremely unsightly in appearance, and also had the disadvantage that when a person moved on the tread plate ho, a frictional sound was generated between the tread plate ho and the riser plate 2, which was likely to cause the so-called stomping phenomenon. Ta.

The present invention has been made with the aim of improving all of the drawbacks of the conventional stairs mentioned above.

Hereinafter, the present invention will be explained in detail based on the embodiment shown in FIG.

In the present invention, a flat plate-shaped receiver made of solid wood, laminated wood, etc. is connected from the upper surface 2 of the plate 1, through the front side 5 of the front surface 3 and the lower surface 4, to the one end 6 of the plate 1. A decorative board 7 made in a shape that hangs down from the lower surface 4 of the receiver is attached to the board 1 with adhesive, nails, etc., and the tread board 8 and riser board 9 are integrally formed. This is a hollow staircase, and the tips 10 of the risers 9 are fixed to the rear surfaces 11 of the adjacent treads 8 using adhesive, nails, or the like.

Incidentally, the tip 10 of the riser board 9 may be fitted into a groove previously carved in the deep part of the surface of the footboard 8.

An example of the method for manufacturing the decorative board 7 used in the present invention will be explained in detail based on FIG. 3. , vinyl chloride resin sheet,
A decorative veneer 13 having a thickness of 0.2 to 2.0 mm and having flexibility such as printed paper is pasted with an adhesive interposed therebetween, and a waste veneer 14 having flexibility is also pasted on the back side.

The waste veneer 14 is not exposed on the surface of the staircase, which is the final product.

Next, V-shaped grooves 15 with an angle of 90' are carved at predetermined positions from the decorative veneer 13 side and the sacrificial veneer 14 side, respectively.

At this time, the ■-shaped groove 15 is a so-called ■-type groove in which the decorative veneer 13 (or the waste veneer 14) and the substrate 12 are carved, and only the waste veneer 14 (or the decorative veneer 13) is left. It is the law.

The decorative board 7 created in this way may be bent into the desired shape by bending it along the pattern grooves 15 before being attached to the plate, or the receiver may be bent into the desired shape before being attached to the plate. It may be bent along the plate surface to form a desired shape.

Figures 4 and 5 show different embodiments of the present invention.
The figure shows a method of manufacturing a decorative board 7, in which a U-shaped groove 1 is formed on the decorative veneer 13 side of the part of the decorative board 7 that is installed on the upper surface 2 of the board 1.
6 is carved, the receiver is attached to plate 1 as shown in Fig. 5, and U
The mold grooves 16 are used to prevent slippage.

Of course, in addition to the U shape, a U shape or a square shape may be used.

Further, a non-slip component may be buried in the U-shaped groove 16.

The stairs of the present invention are constructed as described above, and the present invention can produce the following effects.

(1) The decorative board can be easily attached to the board, so during construction work, only the board can be installed, and after the construction of other parts is completed, the decorative board can be attached to the board. , there is no need for special curing during construction work, which was required for conventional stairs.

(2) Since the tread and riser are completely integrated, it is possible to prevent tread noise caused by contact between the tread and the riser.

(3) Since the tread and riser are made of a single piece of decorative board, the continuity of the surface pattern, especially in the case of a wood grain pattern, can be maintained, resulting in an extremely pleasing appearance.

(4) There is no need for special grooves for inserting risers into the back of the tread, and construction is extremely easy.
