Description

本発明は、ドアや壁材などの内装用品や家具類などの収納用品に用いられる化粧溝を施した化粧板に係り、更に詳しくは、一枚の基板から種々の形状の化粧溝を作製した化粧板に関するものである。 The present invention relates to a decorative board provided with a decorative groove used for interior goods such as doors and wall materials and storage goods such as furniture, and more specifically, decorative grooves of various shapes are produced from a single substrate. It is about a decorative board.

従来、ドアや壁材などの内装用品や家具類などの収納用品には、表面にＶ字形、凵字形、逆台形状の化粧溝加工がなされている。この化粧溝加工は、通常、特許文献１の従来技術に示すように、通常、基板の表面にＶ字形の切削溝加工を行った後、切削面に化粧シートを貼り付けて作製されている。 Conventionally, interior goods such as doors and wall materials, and storage goods such as furniture have been subjected to V-shaped, bowl-shaped and inverted trapezoidal decorative groove processing on the surface. As shown in the prior art of Patent Document 1, this decorative groove processing is usually produced by applying a V-shaped cutting groove on the surface of a substrate and then attaching a decorative sheet to the cutting surface.

また、特許文献１のように、Ｖ字形の切削溝の底部に平坦部を設けた後に、切削面に化粧シートを貼り付けてＶ字形の化粧溝加工がなされている化粧板もある。 In addition, there is a decorative plate in which a V-shaped decorative groove is processed by attaching a decorative sheet to a cutting surface after providing a flat portion at the bottom of a V-shaped cutting groove as in Patent Document 1.

そして、特許文献２のように、基板の裏面からＶ字形の切削溝加工を行い、その後この切削面を広げて台板上に接着させて基板の表面にＶ字形の化粧溝加工がなされている化粧板もある。 And like patent document 2, V-shaped cutting groove processing is performed from the back surface of a board | substrate, and after that, this cutting surface is expanded and it adheres on a base plate, and V-shaped decorative groove processing is made | formed on the surface of the board | substrate. There is also a decorative board.

さらに、特許文献３のように、基板の裏面から２ヶ所のＶ字形の切削溝加工を行った後、切削面を接着して断面を略Ｊ字形にした基板を２枚用意し、嵌合溝を設けた台板にこの略Ｊ字形の基板を嵌め込むことで、基板の表面にＶ字形の化粧溝加工がなされている化粧板もある。 Further, as in Patent Document 3, two V-shaped cutting grooves are processed from the back surface of the substrate, and then two substrates having a substantially J-shaped cross section are prepared by bonding the cutting surfaces. There is also a decorative board in which a V-shaped decorative groove is formed on the surface of the substrate by fitting the substantially J-shaped substrate into the base plate provided with the base plate.

しかし、従来技術である切削面に化粧シートを貼り付ける方法では、化粧溝の幅が小さかったり、溝の深さが大きかったりした場合には、化粧シートが化粧溝の底まで十分入りこまずに化粧シートが浮き上がってしまうという問題があった。そして、逆に浮き上がりを防止するために化粧シートを溝の底に押しつけると化粧シートが破れてしまい、破損した部分から吸水を起こしてしまい、耐久性が低下するという問題があった。 However, with the conventional method of attaching a decorative sheet to the cutting surface, if the width of the decorative groove is small or the depth of the groove is large, the decorative sheet does not sufficiently enter the bottom of the decorative groove. There was a problem that the decorative sheet floated. On the other hand, when the decorative sheet is pressed against the bottom of the groove to prevent lifting, the decorative sheet is broken, causing water absorption from the damaged portion, resulting in a decrease in durability.

また、特許文献１に示す化粧板では、化粧溝の底部に平坦部を設けたことによって、化粧シートの浮き上がりや破損は防止できるが、Ｖ字形の化粧溝のシャープさといった質感を表現することが困難であるという問題があった。 Further, in the decorative plate shown in Patent Document 1, by providing a flat portion at the bottom of the decorative groove, the decorative sheet can be prevented from being lifted or damaged, but a texture such as the sharpness of the V-shaped decorative groove can be expressed. There was a problem that it was difficult.

そして、特許文献２に示す化粧板では、化粧シートがＶ字形の化粧溝の底まで密着していることから、化粧溝のシャープさを表現することはできるが、Ｖ字形の化粧溝を形成するために台板に接着することで基板と台板の間に空気層ができてしまうことから、プレス成形によって最終商品を製造することができない。
従って、最終商品となった際、中空部分に十分な強度を付与できないという問題があった。 And in the decorative board shown in patent document 2, since the decorative sheet has adhered to the bottom of the V-shaped decorative groove, the sharpness of the decorative groove can be expressed, but the V-shaped decorative groove is formed. Therefore, since an air layer is formed between the substrate and the base plate by bonding to the base plate, the final product cannot be manufactured by press molding.
Therefore, when it became the final product, there was a problem that sufficient strength could not be given to the hollow part.

さらに、特許文献３に示す化粧板では、Ｖ字形の切削溝加工を行い、断面を略Ｊ字形にした基板を２枚用意する必要があり、また、台板にも嵌合溝を設ける加工を行わなければならず、作業工程が複雑になるという問題があった。 Furthermore, in the decorative board shown in Patent Document 3, it is necessary to prepare a V-shaped cutting groove and prepare two substrates having a substantially J-shaped cross section, and to provide a fitting groove on the base plate. There is a problem that the work process becomes complicated.

本発明は、上記した従来の問題点に鑑みてなされたものであって、化粧溝の底部まで化粧シートを密着させつつ、化粧溝のシャープさを損なわない基板であって、なおかつ、１枚の基板のみで化粧溝を作製し、台板に加工を必要としない化粧板を提供することを目的とする。 The present invention has been made in view of the above-described conventional problems, and is a substrate that does not impair the sharpness of the decorative groove while keeping the decorative sheet in close contact with the bottom of the decorative groove, and one sheet. An object of the present invention is to provide a decorative plate in which a decorative groove is produced only with a substrate and the base plate does not require processing.

ここで、本発明に用いる基板は、木材はもちろんのこと、合板、ＭＤＦ、ＬＶＬ、パーティクルボードなどの木質材料系の板材にも用いることができる。また、珪酸カルシウム板のような無機材料系の板材にも用いることができる。 Here, the board | substrate used for this invention can be used also for board | plate materials of woody materials type | system | groups, such as a plywood, MDF, LVL, a particle board as well as wood. Moreover, it can also be used for an inorganic material-based plate material such as a calcium silicate plate.

本発明に用いる化粧シートは、基板に接着でき表面を化粧することができるものであれば特に限定されず、建材の化粧用材料として一般的に用いられている突き板を用いることができる。また、塩化ビニル樹脂、ポリエチレン樹脂、ポリプロピレン樹脂などの合成樹脂シートも用いることができる。なお、これらの突き板や合成樹脂シートには、適宜、色や模様をつけておいてもよい。 The decorative sheet used in the present invention is not particularly limited as long as it can be adhered to the substrate and can make the surface, and a veneer generally used as a decorative material for building materials can be used. Moreover, synthetic resin sheets such as vinyl chloride resin, polyethylene resin, and polypropylene resin can also be used. These veneer plates and synthetic resin sheets may be appropriately colored or patterned.

なお、本発明においては、側面視Ｗ字形に配置された４つの底部構成面と、側壁面と間に、化粧シートに平行な水平底部構成面を設けておくことが好ましい。
ここで、水平底部構成面の幅については、０．０５〜１．０ｍｍにすることが好ましく、さらには０．１〜０．３ｍｍにすることが好ましい。
その理由は、かかる遊びを作っておくことによって、切削面を折り曲げて接着した際に、化粧シートが折り曲げ部分で伸びることによって、破断したり、白化したりすることを防止できるからである。
また、かかる遊びを作っておくことによって、従来は冬場の温度が低い時期において、化粧シートの破断を防止するために必要であった、基板の加温の前処理作業を行うことなく切削面を折り曲げることができるからである。
従って、平坦部の幅が０．１ｍｍよりも小さいと折り曲げた際の化粧シートの破断や白化を十分には防止できない。また、平坦部の幅が０．３ｍｍよりも大きいと折り曲げた際に折り曲げ部で化粧シートが余り、外観が悪くなることになる。 In addition, in this invention, it is preferable to provide the horizontal bottom part construction surface parallel to a decorative sheet between the four bottom part construction surfaces arrange | positioned by side view W shape, and a side wall surface.
Here, the width of the horizontal bottom portion constituting surface is preferably 0.05 to 1.0 mm, and more preferably 0.1 to 0.3 mm.
The reason is that by making such play, it is possible to prevent the decorative sheet from being broken or whitened by being stretched at the bent portion when the cut surface is bent and bonded.
In addition, by making such play, the cutting surface can be made without the pre-treatment work of heating the substrate, which was conventionally necessary to prevent the decorative sheet from being broken at a low temperature in winter. This is because it can be folded.
Therefore, when the width of the flat portion is smaller than 0.1 mm, the decorative sheet cannot be sufficiently broken or whitened when folded. On the other hand, if the width of the flat part is larger than 0.3 mm, the decorative sheet is left in the folded part when folded and the appearance is deteriorated.

一方、水平底部構成面の厚みについては、略化粧シートに達する状態であればよい。これは、折り曲げの際に折り曲げ作業が困難とならなければ、厚みには限定されないという意味であり、従って、水平底部構成面にわずかに基板を残した状態で切削してもよいし、あるいは、化粧シートのみを残して基板を全て切削してもよい。 On the other hand, the thickness of the horizontal bottom portion constituting surface may be in a state of reaching substantially the decorative sheet. This means that the thickness is not limited as long as the bending operation is not difficult at the time of bending, and therefore, the substrate may be cut with a slight substrate left on the horizontal bottom component surface, or The entire substrate may be cut leaving only the decorative sheet.

請求項１の発明に係る化粧板は、基板と、この基板表面を覆う化粧シートとを備え、表面に化粧溝が形成された化粧板であって、表面に化粧シートが貼着された基板の裏面に４つ以上の底部構成面からなる凹凸底部を有する切削溝が形成された化粧板形成材の、切削溝の側壁面と、底部構成面とが接着されることによって、表面に化粧溝が形成される構成にしてある。
従って、裏面を折り曲げることによって、化粧シートが貼着された状態で表面に化粧溝を形成することができることから、化粧溝の底部まで化粧シートを密着させつつ、化粧溝のシャープさを損なわない化粧板を作製することができる。 A decorative board according to the invention of claim 1 is a decorative board that includes a substrate and a decorative sheet that covers the surface of the substrate, and has a decorative groove formed on the surface, and the decorative sheet is attached to the surface of the substrate. The decorative groove is formed on the surface by bonding the side wall surface of the cut groove and the bottom component surface of the decorative plate forming material in which the cut groove having the concave and convex bottom portion having four or more bottom component surfaces is formed on the back surface. The structure is formed.
Therefore, since the decorative groove can be formed on the surface with the decorative sheet attached by folding the back surface, the makeup does not impair the sharpness of the decorative groove while bringing the decorative sheet into close contact with the bottom of the decorative groove. A plate can be made.

請求項２および請求項３に係る化粧板は、切削溝が、垂直な両側壁面と、頂点部分が９０°の角度を持つ側面視Ｗ字形に配置された４つの底部構成面とを備え、両側壁面および４つの底部構成面の端縁が略化粧シートに達していて、４つの底部構成面のうち、側壁面側の底部構成面と側壁面とが接着されることによって、表面に断面Ｖ字形の化粧溝が形成される構成にしてある。また、側壁面の高さと、４つの構成面の切削溝の高さ方向の長さが同じである構成にしてある。
従って、折り曲げた際に９０°の角度を持つ側壁面と、底部構成面の９０°の角度を持つ頂点部分とが接着され、その側壁面の長さと底部構成面の長さが同じであることから、折り曲げた後の化粧板の裏面がフラットになり、台板に嵌合溝の加工を必要せずに表面にＶ字形の化粧溝を施した化粧板を作製することができる。
さらに、化粧板の裏面がフラットになっていることから、プレス加工によって台板に化粧板を固定することができ、中空構造とならずに強度を保持した化粧建材を作製することができる。 The decorative board according to claim 2 and claim 3 is provided with cutting grooves provided on both side wall surfaces that are perpendicular to each other, and four bottom constituent surfaces that are arranged in a W-shape in a side view with the apex portion having an angle of 90 °. The edge of the wall surface and the four bottom component surfaces reaches the decorative sheet, and among the four bottom component surfaces, the bottom component surface and the side wall surface on the side wall surface side are bonded to each other, whereby the surface has a V-shaped cross section. The decorative groove is formed. Further, the height of the side wall surface and the length in the height direction of the cutting grooves of the four constituent surfaces are the same.
Therefore, when bent, the side wall surface having an angle of 90 ° and the apex portion having the 90 ° angle of the bottom surface are bonded, and the length of the side wall surface is the same as the length of the bottom surface. Therefore, the back surface of the decorative plate after being bent becomes flat, and a decorative plate having a V-shaped decorative groove on its surface can be produced without the need to process the fitting groove on the base plate.
Furthermore, since the back surface of the decorative plate is flat, the decorative plate can be fixed to the base plate by pressing, and a decorative building material that maintains strength without having a hollow structure can be produced.

請求項４の発明に係る化粧板は、側面視Ｗ字形に配置された４つの底部構成面と、側壁面と間に、化粧シートに平行な０．０５〜１．０ｍｍの幅の水平底部構成面を備えている構成にしてある。
従って、かかる遊びがあることから、切削面を折り曲げた際に、化粧シートが折り曲げ部分で伸びることによる破断や白化を防止することができる。
また、冬場の温度が低い時期においても、化粧シートの破断を防止するための基板の加温を行うことなく切削面の折り曲げ作業を行うことができる。 A decorative board according to a fourth aspect of the present invention is a horizontal bottom structure having a width of 0.05 to 1.0 mm parallel to the decorative sheet between four bottom structure surfaces arranged in a W shape in a side view and a side wall surface. It is the structure provided with the surface.
Therefore, since there is such play, it is possible to prevent breakage and whitening due to the decorative sheet extending at the bent portion when the cutting surface is bent.
Further, even when the temperature in winter is low, the cutting surface can be bent without heating the substrate to prevent the decorative sheet from being broken.

請求項５の発明に係る化粧板は、切削溝が、基材を略化粧シートに達するまで切削形成された垂直な両側壁面と、基材を略化粧シートに達するまで切削形成された化粧シートに平行な第１水平底部構成面を両側に備え、両第１水平底部構成面からそれぞれ切削溝の開口方向に垂直に立ち上がる２つの垂直底部構成面と、この垂直底部構成面と連接する第１水平底部構成面と平行な第２水平底部構成面とを備え、側壁面と第１水平底部構成面および垂直底部構成面とが接着されることによって、表面に断面略凵字形の化粧溝が形成される構成にしてある。
従って、裏面を折り曲げることによって、化粧シートが貼着された状態で表面に化粧溝を形成することができることから、化粧溝の底部まで化粧シートを密着させつつ、化粧溝のシャープさを損なわない凵字形の化粧溝を施した化粧板を作製することができる。 The decorative board according to the invention of claim 5 includes a vertical both-side wall surface in which the cutting grooves are formed by cutting until the base material reaches the decorative sheet, and a decorative sheet formed by cutting the base material until the base material reaches the decorative sheet. Two first horizontal bottom constituent surfaces that are provided with parallel first horizontal bottom constituent surfaces on both sides, and rise from the first horizontal bottom constituent surfaces perpendicularly to the opening direction of the cutting groove, respectively, and a first horizontal that is connected to the vertical bottom constituent surfaces A second horizontal bottom component surface parallel to the bottom component surface, and the side wall surface and the first horizontal bottom component surface and the vertical bottom component surface are bonded to form a substantially groove-shaped decorative groove on the surface. The configuration is as follows.
Therefore, by folding the back surface, the decorative groove can be formed on the surface with the decorative sheet attached, so that the decorative sheet is brought into close contact with the bottom of the decorative groove and the sharpness of the decorative groove is not impaired. A decorative board provided with a letter-shaped decorative groove can be produced.

請求項６の発明に係る化粧板は、側壁面の高さと、第１水平底部構成面の幅と垂直底部構成面の高さとの合計とが同じ長さである構成にしてある。
従って、折り曲げた後に化粧板の裏面がフラットになり、台板に嵌合溝の加工を必要せずに表面に凵字形の化粧溝を施した化粧板を作製することができる。
さらに、化粧板の裏面がフラットになっていることから、プレス加工によって台板に化粧板を固定することができ、中空構造とならずに強度を保持した化粧建材を作製することができる。 The decorative board according to the sixth aspect of the invention is configured such that the height of the side wall surface and the sum of the width of the first horizontal bottom component surface and the height of the vertical bottom component surface are the same length.
Therefore, the decorative plate can be produced in which the back surface of the decorative plate becomes flat after being bent, and the base plate is provided with a square-shaped decorative groove on the surface without the need for processing the fitting groove.
Furthermore, since the back surface of the decorative plate is flat, the decorative plate can be fixed to the base plate by pressing, and a decorative building material that maintains strength without having a hollow structure can be produced.

請求項７の発明に係る化粧板は、切削溝が、基材を略化粧シートに達するまで切削形成された垂直な両側壁面と、基材を略化粧シートに達するまで切削形成された化粧シートに平行な第１水平底部構成面を両側に備え、両第１水平底部構成面からそれぞれ切削溝の開口方向に垂直に立ち上がる２つの垂直底部構成面と、この垂直底部構成面と連接する第１水平底部構成面と平行な第２水平底部構成面と、両第１水平底部構成面と両側壁面との間に側面視Ｖ字形底部構成面を備え、第１水平底部構成面と第１水平底部構成面側のＶ字形底部構成面とが接着され、側壁面と側壁面側のＶ字形底部構成面および垂直底部構成面とが接着され、かつ、第１水平底部構成面と第１水平底部構成面側のＶ字形底部構成面との接着部の表面が基板表面に折り返されて接着されることによって、表面に断面Ｖ字形の化粧溝が形成される構成にしてある。
従って、切削面を折り曲げて接着した際に、基板が巻き込まれた状態で化粧溝の開口部が形成されることから、化粧溝の強度が向上した化粧板を作製することができる。 The decorative board according to the invention of claim 7 includes a vertical both-side wall surface in which the cutting grooves are formed by cutting until the base material reaches the decorative sheet, and a decorative sheet formed by cutting the base material until the base material reaches the decorative sheet. Two first horizontal bottom constituent surfaces that are provided with parallel first horizontal bottom constituent surfaces on both sides, and rise from the first horizontal bottom constituent surfaces perpendicularly to the opening direction of the cutting groove, respectively, and a first horizontal that is connected to the vertical bottom constituent surfaces A second horizontal bottom configuration surface parallel to the bottom configuration surface, and a V-shaped bottom configuration surface in side view between both first horizontal bottom configuration surfaces and both side wall surfaces, the first horizontal bottom configuration surface and the first horizontal bottom configuration The V-shaped bottom constituting surface on the surface side is bonded, the V-shaped bottom forming surface and the vertical bottom forming surface on the side wall surface side are bonded, and the first horizontal bottom forming surface and the first horizontal bottom forming surface are bonded.
