Description

[Detailed description of the invention] The present invention is a V made of plywood or the like with a core made of paper, synthetic resin, or essential material suitable for use as side plates of unit shelves, shelf boards, etc.
This invention relates to a plate-like body sandwiched and fixed between surface plates formed by closing bending grooves such as character grooves.

Conventionally, side panels and shelf boards of unit shelves have been made of wooden boards with a resin decorative board overlay plywood adhered to the outside surface, but these are heavy and prone to warping, etc.
Moreover, it had the disadvantage that the plywood of the resin decorative board overlay plywood could be seen on the outer surface, which was undesirable in terms of design.

The present invention was developed in view of the above circumstances, and is lightweight, has high compressive strength, especially strength against bending and torsion, has an extremely beautiful appearance, and can be easily changed in shape and thickness depending on the purpose. It is an object of the present invention to provide a plate-shaped body that has good machinability and is easy to manufacture.

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

FIG. 1 is a partially cutaway perspective view of an embodiment of the present invention.
is a lattice-shaped core made of a synthetic resin board or a board made of a wood-based material such as plywood, and is disposed between the front plates 33 and fixed integrally with the front plates 3, 3.

As shown in FIG. 2, the core 1 has a notch 2a formed from the upper side of one core member 1a toward the other side, and the other core member 1a intersects with the core member 1a. A notch 2b is formed from the lower side of 1b toward the other side, and the notch 2a of the core component 1a and the core structure are formed so that one core component 1a and the other core component 1b intersect. It is fitted into the notch 2b of the core constituent material 1b which intersects with the material 1a.

On the other hand, to explain the surface plate 3VC, first, as shown in FIG. 3, a substrate 4 made of a wood-based material such as plywood, particle board, ... Or a synthetic resin sheet (film) such as a film, a strong and flexible decorative sheet or film such as cloth or paper 5 - simply referred to as a "decorative sheet"
Paste.

A printed pattern such as wood grain or the like is suitably applied to the surface of the decorative sheet 5.

Therefore, as shown in Fig. 3, the thickness t of the target plate-shaped body is
and bending grooves 6 with a V-shaped cross section that reach the decorative sheet 5 but do not damage it at intervals corresponding to Lvc.
...... are opened in parallel in the longitudinal direction.

The bending groove 6 is formed by cutting with a circular saw or cutter with a saw blade having a predetermined edge angle, and the angle θ of the course of the bending groove 6 is determined according to the present embodiment. In the example, about 900
shall be.

After that, the core constituent materials 1a, 1 of the lattice-shaped core 1 are
The decorative sheet 5 is arranged and fixed so that the lower side of b is in contact with the substrate 41111II of the surface plate 3, and the decorative sheet 5 is folded so as to close the bending groove 6 formed in the substrate 4 as shown in FIG. By bonding the groove walls of the bending groove 6 with adhesive, a plate-like body whose outer surface is covered with the decorative sheet 5 as shown in FIG. 1 is completed.

Incidentally, the core body 1 button and the surface plate 3 are not limited to the above embodiments, and can be modified in various ways.

FIG. 5 is a partially cutaway perspective view of a second embodiment, which is a modification of the previous embodiment, and FIG. 6 is a sectional view thereof.

Reference numeral 1 denotes a core body formed by stacking corrugated cardboard sheet flutes so as to be juxtaposed in the thickness t direction, and each core body 1' is arranged between face plates 3', and the face plate 3' has its front surface. An arcuate edge I is formed at the portion.

As shown in FIG. 1, the surface plate 3' is made by pasting a decorative sheet 5' on a substrate 4' as in the previous embodiment. As shown in FIG. 1, a large number of thin grooves 8 are formed in parallel in the longitudinal direction at appropriate locations in the decorative sheet 5' to reach the back surface of the decorative sheet 5' without damaging it, and grooves 8 for bending are provided in the same way as in the previous embodiment. Groove 6
' has also been opened in parallel.

As shown in FIGS. 6-1 and 8, a columnar core made of a wood-based material is provided, in which a core 1' is disposed and fixed on the surface of a substrate 4', and a circular arc-shaped portion 9 is formed in a part of the core 1'. The body 1a and the columnar core 1b with a rectangular cross section are also arranged and fixed, and the narrow groove 8 is filled with adhesive so as to be aligned with the arcuate portion 9 of the columnar core 1a.
By closing the bending grooves 6' as well as closing the bending grooves 6', a plate-like body having a circular arc-shaped edge 1 formed in a part as shown in FIGS. 5 and 6 is completed.

Note that the columnar cores 1a and 1b may not be used depending on the case.

FIG. 9 is a sectional view illustrating the manufacturing process of a third embodiment, which is a modification of the above embodiment.

1"3" is a flat core with a square cross section made of plywood particle board, hardboard, etc., and 1"b is a columnar core with a square cross section made of wood.

2 is a surface plate, and the surface plate! As shown in Fig. 9, the bending grooves σ and σ are arranged in a W-shape on the substrate l, and the bending grooves ``, C'' are closed and the chamfering force is applied. The flat core body 1''a and the columnar core body fb are brought into contact with the substrate A' of the surface plate, and the substrate Z
It is fixed so that it becomes one with the

Although the button and columnar core bodies 1b, 1b are arranged and fixed in the longitudinal direction in the above embodiment, they may be arranged and fixed in the width direction.

When used as a side plate of a shelf, a shelf support may be fixed to the columnar core.

In addition, a paper tube made of chip ball or yellow ball with a circular cross section cut to an appropriate length may be used as the core instead of or together with the core, or cardboard can be connected in a honeycomb shape. may be used as the core.

Since the present invention is constructed as described above, it has high compressive strength, especially strength against bending and torsion, and is suitable for use as shelf boards of unit shelves, etc. The core body is buttoned with a surface plate and is not visible from the outside. Since there is no such material, it is possible to use various materials such as waste materials, and it is possible to save resources and reduce product costs.

Since there are many hollow parts, it is possible to reduce the weight, and its shape and thickness can be changed in various ways depending on the purpose.It is also easy to saw, and is extremely convenient. .

Moreover, since the surface is buttoned with a decorative sheet with a printed pattern such as wood grain, it has a luxurious and beautiful appearance similar to natural wood, and has high utility value, and is extremely effective in modern times where high-quality natural wood is scarce. .
