Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible board material that can be used for multiple purposes, such as the seat or back of a chair, or as a wall covering material.

Until now, there have been no wood-based flexible boards that can be used for multiple purposes, such as chair seats or backrests, or wall coverings, and most of them have been made using metal hinge members, such as hinges. Alternatively, there is one in which the part connecting the plates made of synthetic resin is formed by a thin part made of synthetic resin, and the thin part is used as a hinge part.

However, the appearance of such hinge members and thin parts is not made of wood-based materials, and it is not possible to obtain a uniform appearance with other parts made of wood-based materials. If a hinge or the like is used, the number of parts will increase, which will increase the cost accordingly.

On the other hand, it is easy to curve to suit the human body shape, and it can be used for chairs that are not flat, such as chaise longues, but need to have a curved surface to suit the body shape. The appearance of a flexible plate material that is easy to install and that can simplify the assembly of chairs during assembly is eagerly awaited.

In addition, even if there is some unevenness on the base, it is desired to develop flexible boards made of wood-based materials that can be easily installed and can be bent to accommodate the uneven surface of the base. It is rare.

Therefore, the main object of the present invention is to provide a flexible board whose outer surface is formed of a rigid strip board made of a wood-based material and a decorative veneer made of a wood-based material, and which is capable of being bent. and its manufacturing method.

Hereinafter, the present invention will be explained in detail according to embodiments shown in the drawings.

FIG. 1 is a perspective view of a chair using an embodiment of the present invention as a seat plate and a backrest, and FIG. 2 is a side view thereof.

Reference numeral 1 denotes a flexible plate material that constitutes the backrest 7 and seat 8 of the chair.

As shown in FIG. 3, this flexible plate material 1 is made of a high-quality natural material on one surface of a strong and flexible sandwiching sheet 2 made of woven fabric such as nylon fabric or non-woven fabric made from polyester or the like. Decorative veneers 3 made of wood-based materials, such as natural wood decorative veneers made by slicing wood into 0.2 mm to 1 mm pieces, are laminated with a hot melt adhesive formed into a film, and then sandwiched together. On the other surface of the sheet 2, a board 4 made of a wood-based material such as a natural wood board such as cedar or cypress, plywood, or laminated wood,
They are laminated with a hot-melt adhesive formed into a film, and the adhesive is heated and melted, then cooled and solidified to form a sandwich sheet 2 and a decorative veneer 3.
A laminate is also formed by bonding the plate members 4 and 4 together.

That is, the flexible plate material 1 is formed from the surface of the plate material 4 of the laminate on the side opposite to the sandwiching sheet 2 side,
As shown in FIG. 3, a plurality of parallel V-shaped grooves 5 with a V-shaped cross section reaching the surface of the sandwiching sheet 2 without damaging it are opened using a grooving blade such as a cutter.
The plate material 4 is divided into a band-like plate 8 having a substantially trapezoidal cross section, and the sandwiching sheet 2 and the decorative veneer 3 are formed to be flexible at the V-shaped groove 5 portion. In addition, at the V-shaped groove 5 portion, a through hole may be provided in the band plate 6, the sandwiching sheet 2, and the decorative veneer 3 to improve air permeability.

One end of the flexible board 1 is fixed to the backrest forming the upper half of the rear legs 9a, 9b of the chair with wood screws, etc. As shown, a locking hole 10 having a circular cross section is formed, and the rear legs 9 are fixed to the rear legs 9a, 9b so as to project forward from approximately the center of the rear legs 9a, 9b.
Seat bodies 11c, 11 made of the same material as a, 9b
The locking hole 10 is formed to be locked to a protruding pin 12 provided protrudingly from the front end of b.

At normal times, the flexible plate 1 is attached to the protruding pin 12 to support the backrests of the rear legs 9a, 9b and the seat body 1.
1a, 11b, and is fixed to the upper edge of the backrest part 7.
and a seat portion 8. When not in use, the flexible plate 1 is removed from the protruding pin 12, and the seat bodies 11a, 11b are folded inward at the hinges 13a, 13b, as shown in FIG.

Next, another embodiment of a wall covering material using a flexible plate material will be described.

FIG. 6 is a perspective view of the example, and FIG. 7 is a sectional view of the example.

2' is a strong and flexible sandwiching sheet, and the sandwiching sheet 2' is impregnated with a hot melt adhesive.

3' is a decorative veneer laminated on one side of the sandwiching sheet 2', and 6' is a band-shaped plate with a rectangular plane and approximately trapezoidal cross section that is attached to the other side of the sandwiching sheet 2'. be.

A decorative veneer 3' is laminated on the surface of the sandwiching sheet 2', and a plurality of strip plates 6' are arranged in parallel on the other surface, and a V-shaped groove 5'a is formed between the strip plates 6'. ，
5'b are formed vertically and horizontally. Thereafter, the hot melt adhesive impregnated into the sandwich sheet 2' is melted by hot pressing, and the melted hot melt adhesive is cooled and solidified to form the sandwich sheet 2', the decorative veneer 3', and the strip board. Glue 6'. Note that the shape of the strip plate 6' may be modified as appropriate, but if a long plate is to be formed, the horizontal V-shaped groove 5'b is perpendicular to the vertical V-shaped groove 5'a. If there are too many belt-shaped plates 6', the flexible plate material will bend at the V-shaped groove 5'a, making it difficult to adhere to a wall surface, etc., so it is necessary to appropriately select the combination of band-shaped plates 6'.

In order to adhere the decorative veneer 3' to a wall surface as a wall covering material, adhesive may be applied to the surface of the decorative veneer 3' and the decorative veneer 3' may be adhered to the wall surface. If the wall surface has a curved surface or a corner, the flexible plate material may be bent and bonded at the V-shaped groove 5'a.

Since the present invention is configured as described above, when used as a seat or backrest of a chair, for example, it can be curved to suit the human body shape, and since it is formed in a series, the seat or backrest can be bent. It is easy to attach to the wall, simplifying the assembly work, and when used as a wall covering, it can be easily folded to accommodate the corner or curved surface. It can be bent and pasted, contributing to ease of construction.

In addition, band-shaped boards are convenient because they can be manufactured using relatively narrow or short boards instead of using a single long board. .

The work of adhering the sandwich sheet and the decorative veneer or strip board can be easily done by using a film-like hot-melt adhesive or by impregnating the sandwich sheet with a hot-melt adhesive. Moreover, it has good adhesion. In addition, if you use a hot-melt adhesive whose main component is a vinyl copolymer, the adhesive after curing will be soft, blend well with the sandwich sheet, have strong adhesion, and be flexible. It can also handle bending of plate materials.

The present invention has various excellent effects as described above.
