本考案は樹木の成長過程において、樹幹や大枝
等に発生した瘤や腫脹と呼ばれる異常細胞組織の
杢を利用してなる強化化粧板に関するものであ
る。[Detailed description of the invention] The present invention relates to a reinforced decorative board that utilizes the heather of abnormal cell tissue called lumps and swellings that occur on tree trunks, branches, etc. during the growth process of trees.
カエデ類やクルミ類の樹木に生じた瘤杢は、リ
ボン杢等の放射組織からできた杢と異なつてその
繊維方向が複雑に入り組んでおり、これを切削し
て溌板にすると、その板面に対して繊維方向が直
交或いは直交に近い角度で傾斜して現われる部分
が生じ、杢の模様が美麗で雅趣に富むために、工
芸的価値の高いものが得られる。 Unlike heather formed from radial tissues such as ribbon heather, the heather that occurs on maple and walnut trees has a complicated fiber direction. There are parts where the fiber direction is perpendicular to the grain, or inclined at an angle close to perpendicular to the grain, and the heathered pattern is beautiful and elegant, making it possible to obtain products with high craft value.
しかしながら、上記瘤杢部分はその繊維方向が
板面に対して概ね直交している部分が多いので、
薄板にすると曲げや引張り等の外力で割れの欠け
が容易に生じ、強度的に極めて弱いものである。 However, in many of the above-mentioned bulge areas, the fiber direction is approximately perpendicular to the board surface, so
When made into a thin plate, it easily cracks or chips due to external forces such as bending or tension, and is extremely weak in terms of strength.
従つて、従来から瘤杢の薄板は、主として家具
等の表面材のように、あまり強度的な性能が要求
されない部分のみに利用され、建築用の床材のよ
うに強度や耐摩耗性、耐汚染性が要求されるとこ
ろでは、欠けや、繊維間空間への塵埃の付着等の
問題が生じるために殆んど使用できなかつた。 Therefore, conventionally, thin boards made from bulges have been used only for areas that do not require strong performance, such as surface materials for furniture, and for areas that do not require strong performance, such as flooring materials for buildings. In places where stain resistance is required, problems such as chipping and adhesion of dust to the spaces between fibers occur, so that they can hardly be used.
又、瘤杢薄板表面に耐汚染性を付与するには、
樹脂塗装を行うことも考えられるが、樹脂塗装で
は樹脂液が瘤杢薄板の表層部分と繊維間空隙の大
きい部分のみに浸透するだけであるから、樹脂に

足するばかりでなく、表面のみに樹脂被覆層が形
成されるだけであるから、杢内部の繊維間の結合
力が弱くて床材として用いた場合に衝撃により割
れが生じる。 In addition, in order to impart stain resistance to the surface of the heather thin plate,
It is possible to apply resin coating, but with resin coating, the resin liquid only penetrates into the surface layer of the heather thin plate and the areas with large interfiber voids, so the fiber luster caused by the resin does not appear and lacks depth. Not only does it lack a three-dimensional effect, but because the resin coating layer is only formed on the surface, the bonding force between the fibers inside the heather is weak, and when used as a flooring material, cracks occur due to impact.
さらに、瘤杢薄板を所望寸法に切断する場合、
塗装後は塗膜に割れや亀裂等を発生させる虞れが
あるので、塗装前に切断加工が行われるが、脆い
ために角欠け等が生じ、又、サンダーがけによつ

上表面に繊維が毛羽立ち状態になつているので、
平滑な鏡面の塗面を形成するには多数回、重ね塗

う問題点を有する。 Furthermore, when cutting the bulge thin plate to desired dimensions,
After painting, there is a risk of cracks or cracks in the paint film, so cutting is performed before painting, but the brittleness may cause corners to be chipped, and sanding is required to obtain thickness accuracy. However, due to the weak bonding force between the tissues, the heather is destroyed and the thickness accuracy is not achieved, and the fibers become fluffy on the surface.
In order to form a smooth, mirror-like painted surface, it is necessary to apply multiple coats many times, which poses a problem in that the work is troublesome.
本考案はこのような問題点をなくするために、

It consists of a resin-injected thin plate made by injecting and hardening a transparent synthetic resin liquid into the thin plate, and at least one layer of grained or straight-grained wood veneer adhered to the underside of the resin-injected thin plate. The objective is to provide a reinforced decorative board that exhibits a luster and a variety of patterns that cannot be obtained by other methods.

硬化させてなるものである。 The embodiments of the present invention will be explained with reference to the drawings: 1
is a resin-injected heather thin board, which is made by cutting out the abnormal cell tissue parts called lumps or swellings that occur in trees such as elm, quince, and walnut, so that the wood fibers are oriented in a spiral shape almost perpendicular to the board surface. Obtain a thin plate such as sliced veneer, rotary veneer, sword veneer, etc. with an appropriate thickness, and inject a transparent synthetic resin liquid into the thin plate under pressure, vacuum injection, or vacuum pressure. After injecting by a method such as injection,
It is made by hardening.
2は樹脂注入処理瘤杢薄板1の裏面全面に裏打
材として一体に接着した適宜厚さの板目又は柾目
の木材単板である。 Reference numeral 2 denotes a wood veneer with an appropriate thickness and grain or straight grain, which is integrally bonded to the entire back surface of the resin-injected heathered thin board 1 as a backing material.
瘤杢薄板に注入する合成樹脂液としては、縮合

なるものである。 When the resin is injected into the thin plate of the lump, the resin liquid completely fills the cells of the thin plate of the lump, or the voids and gaps such as knots, cracks, and cracks, and solidifies while impregnating the inside of the plate. The unique heathered pattern can be seen through to the inside, and the fiber direction is perpendicular to the board surface, so the resin-injected heathered thin board has transparency that increases gloss and creates a three-dimensional effect. 1.

い。 As shown in FIGS. 1 and 2, such a thin board 1 was bonded with a wood veneer 2 on the back side to form a reinforced decorative board, but as shown in FIGS. Thin veneer pieces 3, 3, 3, 3 of straight-grained or board-grained resin-injected wood are arranged around the four sides of the treated heathered thin board 1 in the shape of a frame, and this is used as a backing material or as a backing material as described above. It may be attached integrally onto a plurality of wood veneers 2 with grain or straight grain that are not injected with resin.

強度的に優れた化粧板となるものである。 With this structure, chipping of the corners of the central burl board 1 is prevented by the surrounding resin-injected thin wood veneer pieces 3, and further, multiple wood veneers 4 are attached to the back surface.
When bonding and performing actual processing on the peripheral edge surface,
The impact strength of the upwardly protruding portion of the female part 5 is increased, resulting in a decorative board with even greater strength.

る。 In this way, the present invention has been developed by cutting a lump or swollen part of wood to an appropriate thickness, and the inside of the wood fiber has an abnormally oriented part in a spiral shape that is approximately perpendicular to the board surface. A resin liquid-injected curvature thin plate having a diffusely reflecting portion of light rays, which is obtained by injecting and curing a transparent synthetic resin liquid, and one or more layers of plate grain or straight grain bonded to the lower surface of the resin liquid injection-treated curvature thin plate. Since this is a reinforced decorative board made of wood veneer, the resin is injected and hardened even into the inside of the wood veneer, so it has great strength, abrasion resistance, and stain resistance. Not only can it eliminate the adhesion of dust, etc., but since the fibers of the heathered thin plate are perpendicular to the plate surface, the transparency is further increased in that area, and the light rays are diffusely reflected inside the thin plate, causing the fibers to The gloss appears on the surface, and the heather is raised, creating a reinforced decorative board with a three-dimensional and solid feel.

し得るものである。 Furthermore, the diffusely reflected light rays reflect off the cell walls of the fibers, creating a lumpy pattern that varies depending on the viewing direction, unlike conventional veneers made of normal tissue such as wood grain or straight grain, which are injected with resin. It is capable of exhibiting cosmetic properties that have a deep and beautiful craft value that cannot be obtained elsewhere.

が良好となるものである。 In addition, since a wood veneer is attached to the bottom surface of such a resin liquid injection-treated bulge thin plate, when the synthetic resin liquid injected into the bulge heather thin plate hardens, the resin liquid fills the voids of the bulge heather. The backing wood veneer reliably prevents outflow from abnormally oriented areas where the fiber directions are perpendicular to each other, allowing a sufficient amount of resin liquid to be retained inside, increasing transparency and curing. The resin increases the bending rigidity in the direction perpendicular to the fiber direction of the wood veneer, which prevents cracking and chipping, and also allows the wood veneer to be cut from the back side when cutting to the desired size with a saw. Since it is reinforced, it eliminates chipping and cracking and improves dimensional accuracy.
