Description

本発明は、住宅、住宅機器、家具等に使用される額縁構造をした額縁構造戸板に関する。   The present invention relates to a frame structure door plate having a frame structure used for a house, a house device, furniture and the like.

従来、住宅、住宅機器、家具等に使用される戸板として、図６に示すように、縦框４と横框５との内周部に、鏡板８が填め込まれている額縁９が取り付けられた額縁構造戸板がある。   Conventionally, as a doorboard used for a house, housing equipment, furniture, etc., as shown in FIG. 6, a frame 9 in which an end plate 8 is fitted is attached to the inner periphery of the vertical gutter 4 and the horizontal gutter 5. There is a frame door.

この額縁構造戸板として、図７、図８に示すように、木質の枠材を芯材とし、その芯材の表面及び裏面に表面化粧板２を接着剤で貼着し縦框４を、そして、表面化粧板３を接着剤で接着して横框５を形成し、該縦框４と横框５の内周部に前記芯材の一部を突出させ、鏡板８が填め込まれている額縁９で前記芯材の突出部を表裏面から挟持させ接着剤で接着し、前記縦框４及び横框５の内周部に前記額縁９を取り付けて構成した額縁構造戸板が知られている。この額縁構造の戸板において、戸板の角部分における縦框と横框との接合方法は、主として縦框及び横框を４５度に切断し、該切断箇所を直角に継ぐ、いわゆる、留め継ぎ加工と、矩形からなる縦框及び横框を直角に当接させて継ぐ、いわゆる組み継ぎ加工の二つの種類の継ぎ加工方法が用いられてきた。このようにして四周に２本の縦框及び２本の横框によって矩形形状に組まれた框組みの内部に開口部が形成され、該開口部の外周、すなわち、框組みの内周に沿って設けられた額縁を介して鏡板が填め込まれている。   As shown in FIGS. 7 and 8, as the frame structure door plate, a wooden frame material is used as a core material, and a surface decorative board 2 is adhered to the front surface and the back surface of the core material with an adhesive, and a vertical gutter 4 is provided. The surface decorative board 3 is adhered with an adhesive to form a horizontal gutter 5, and a part of the core material is projected from the inner circumference of the vertical gutter 4 and the horizontal gutter 5, and the end plate 8 is fitted. There is known a frame-structure door plate that is configured by sandwiching the protruding portion of the core member from the front and back surfaces with a frame 9 and adhering with an adhesive, and attaching the frame 9 to the inner peripheral portions of the vertical and horizontal ribs 4 and 5. . In this frame-structured door plate, the joining method of the vertical hook and the horizontal hook at the corner portion of the door board is a so-called jointing process in which the vertical hook and the horizontal hook are mainly cut at 45 degrees and the cut portion is joined at a right angle. Two types of splicing methods, so-called splicing, have been used, in which a vertical spear and a horizontal spear made of a rectangle are brought into contact with each other at a right angle. In this way, an opening is formed in the inside of the braid assembled in a rectangular shape by two vertical rods and two horizontal rods on the four sides, and along the outer periphery of the opening, that is, the inner circumference of the rod assembly The end plate is inserted through a picture frame.

また、一側縁部を表面側から切欠して所定幅の表向き段部を形成した一対の縦框表面板と、両端縁部を裏面側から切欠して表向き段部の幅よりも小さい幅の裏向き段部を形成した一対の横框表面板とを枠状に配置し、これら表面板を横框表面板の裏向き段部を縦框表面板の表向き段部に重ねて互いに突き合わせるとともに、その突き合わせ部を仮止めして、縦框表面板と横框表面板との境界部の表面に表向き段部と裏向き段部との幅の差に相当する目地溝を形成した木製ドアがある。（例えば、特許文献１参照）。   In addition, a pair of vertical surface plates in which one side edge is notched from the surface side to form a front-facing step portion having a predetermined width, and both end edges are notched from the back surface side and have a width smaller than the width of the front-side step portion. A pair of recumbent surface plates formed with face-down steps are arranged in a frame shape, and these surface plates overlap each other with the face-down steps of the recumbent surface plate overlapped with the front-facing steps of the vertical surface plate. The wooden door having a joint groove corresponding to the difference in width between the front-facing stepped portion and the back-facing stepped portion on the surface of the boundary portion between the vertical surface plate and the horizontal surface surface plate is temporarily fixed to the butted portion. is there. (For example, refer to Patent Document 1).

特開平５−７１２７２号公報（第２−５頁、第１図、第１２−１４図）。Japanese Patent Laid-Open No. 5-71272 (page 2-5, FIG. 1, FIGS. 12-14).

木質材料は使用される場所の湿度変化等の環境の影響を受け、その含水率が変動し、収縮や膨張が生じやすい。そのために複数の部材の組み合わせからなる木質建材は部材間に隙間等が発生し易い。   Woody materials are affected by the environment such as humidity changes in the place where they are used, and their moisture content fluctuates, and they tend to shrink and expand. Therefore, a wooden building material composed of a combination of a plurality of members is likely to have a gap or the like between the members.

そのため、木質の枠材を芯材とし、その表裏面に木質の表面化粧板からなる框を組み付けて形成し、該框の内部に戸板開口部を設け、さらに、額縁の間に鏡板を挟み込んで、前記框の内周部に、表面裏面から額縁を取り付けてなる額縁構造の戸板が用いられているが、前記額縁構造の戸板において、框と額縁との間は、美観を高め高級感を得るといった意匠的要求や縦框と横框の収縮により外観を損ねることを防止するものとして、縦框横框の額縁側端面に表面側から切欠段部を加工し、該切欠段部によって薄板部を形成し、縦框の長手方向の内側端部と横框の短手方向の左右両端部との間、又縦框と額縁との間、また横框と額縁との間に意図的に目地溝を形成した構成の額縁構造戸板がある。   Therefore, a wooden frame material is used as a core material, and a wall made of a wooden surface decorative board is assembled on the front and back surfaces, a door plate opening is provided inside the wall, and an end plate is sandwiched between the frames. In addition, a frame-structured door plate is used on the inner peripheral part of the frame, and a frame structure is attached to the frame from the front and back surfaces. In the frame-structured door plate, between the frame and the frame, the aesthetic appearance is enhanced and a high-class feeling is obtained. In order to prevent the appearance from being damaged due to the design requirements and shrinkage of the vertical and horizontal planes, a notch step portion is processed from the surface side to the frame side end surface of the vertical and horizontal plane, and the thin plate portion is formed by the notch step portion. The joint groove is intentionally formed between the inner side edge of the longitudinal side of the downside and both left and right side ends of the side of the downside, between the downside and the frame, and between the side and the frame. There is a frame-structure door board with a configuration that forms

しかしながら、木質部材の含水率変動による部材伸縮や切欠加工精度不良、組み付け加工精度不良等の影響で、前記薄板部の先端部と額縁との間に、目隙が発生し易く、これが、かえって外観上目立つことになり、仕上がり精度、外観不良の原因となっていた。   However, due to the influence of member expansion / contraction, notch processing accuracy failure, assembly processing accuracy failure, etc. due to fluctuations in the moisture content of the wood member, gaps are likely to occur between the front end portion of the thin plate portion and the frame, which is rather the appearance. It became conspicuous, causing finishing accuracy and poor appearance.

そのため、上記、特開平５−７１２７２号公報においては、框接合部において、表面材を構成する縦框表面板と横框表面板とに切欠形成する表向き段部と裏向き段部との幅の差によって縦框表面板と横框表面板との接合部に目地溝を形成する構成を有している。さらに、額縁の外周部においても前記裏向き段部と同寸法の裏向き段部を形成し、縦框と額縁との接合部及び横框と額縁との接合において、切欠形成する表向き段部と裏向き段部との幅の差によって目地溝が形成されている。しかも、前記目地溝の幅は、上記表向き段部と裏向き段部との幅の差のみによって決まるので、前記目地溝幅を均一なものとすることができる。   Therefore, in the above-mentioned Japanese Patent Application Laid-Open No. 5-71272, the width of the front stepped portion and the back stepped portion that are notched and formed in the vertical surface plate and the horizontal surface plate constituting the surface material in the flange joint portion. It has the structure which forms a joint groove in the junction part of a vertical gutter surface board and a horizontal gutter surface board by the difference. Further, a back-facing step portion having the same dimensions as the back-facing step portion is formed also in the outer peripheral portion of the frame, and in the joining portion between the vertical hook and the frame and in the joining portion between the horizontal hook and the frame, A joint groove is formed by the difference in width from the back-facing step. In addition, since the width of the joint groove is determined only by the difference in width between the front-facing step portion and the back-facing step portion, the joint groove width can be made uniform.

しかしながら、上記、特開平５−７１２７２号公報に記載の木製ドアの製造方法では、前記目地溝の幅は均一なものとなるが、縦框の額縁側及び横框側端面に上側から切欠段部を加工し、縦框のその箇所に下側突条部を形成し、また、横框の額縁側端面においても、上側から切欠段部を加工し、横框のその箇所に下側突条部を形成し、逆に、額縁の縦框及び横框側の端面には、下側から切欠段部を加工し、額縁のその箇所に、前記下側突条部より長さ寸法の小さな上側突条部を形成し、また、横框の縦框側の端面において、下側から切欠段部を加工し、その箇所において、前記下側突条部より長さ寸法の小さな上側突条部を形成し、前記上側突条部と下側突条部の長さ寸法の差によって、凹条溝、すなわち目地溝を形成する構成となっているので、目地溝の底部は下側突条部で形成されており、すなわち、目地溝の底部は、縦框、横框の表面化粧板の下地板が露出することになる。   However, in the method for manufacturing a wooden door described in JP-A-5-71272, the width of the joint groove is uniform. The lower ridge is formed at that part of the vertical hook, and the notch step is processed from the upper side also at the frame side end face of the horizontal hook, and the lower ridge is formed at that position of the horizontal hook. On the other hand, a notch step is processed from the lower side to the vertical and horizontal end surfaces of the frame, and the upper protrusion having a smaller length than the lower protrusion is formed at that portion of the frame. Form a ridge, and process a notch step from the lower side on the end surface of the vertical ridge side of the horizontal ridge, and form an upper ridge that is smaller in length than the lower ridge at that location. And it becomes the structure which forms a concave groove, ie, a joint groove, by the difference of the length dimension of the said upper side protrusion part and a lower side protrusion part. In the bottom of the eye graben is formed by the lower ridge, i.e., the bottom of the eye graben would stiles, the base plate of the surface veneer of transverse rail is exposed.

このような構成であると、表面化粧板の下地板として、通常良く用いられる合板、中比重繊維板等の欠点が露出することになり、大変見苦しいものとなる。また、これを解消するには細長い目地底部に着色塗装を施すといった、極めて困難な作業が必ず必要となり、作業性に劣り、高価に付くといった問題点があった。また、よほどの熟練工でないと、うまく塗装できず、仕上がりの大変劣るものとなっていた。   With such a configuration, defects such as a plywood and a medium specific gravity fiber board that are commonly used as a base plate of a surface decorative board are exposed, which is very unsightly. Moreover, in order to solve this problem, an extremely difficult operation such as applying a colored coating to the elongated joint base is indispensable, resulting in inferior workability and high cost. Moreover, unless it was a very skilled worker, it could not be painted well and the finish was very inferior.

また、上記、特開平５−７１２７２号公報に記載の木製ドアの製造方法では、額縁の縦框及び横框側の端面及び横框の縦框側の端面に上側突条部が形成され、縦框の額縁側及び横框側端面及び横框の額縁側端面に下側突条部を形成され、それら、上側突条部及び下側突条部が相じゃくり嵌合する構成ゆえ、額縁周縁の上側突条部は、額縁材の一部で構成されることになり、額縁材が、木材無垢からなる場合、上側突条部が、木質材の含水率変動で、伸縮し、ひどい場合は上向きの反りが発生し、目地溝を挟んで、部材間に目隙、段差等が発生し易くなる。   Further, in the method of manufacturing a wooden door described in Japanese Patent Laid-Open No. 5-71272, the upper ridges are formed on the vertical and horizontal side surfaces of the frame and the vertical surface of the horizontal surface. Since the lower ridges are formed on the frame side, the horizontal frame side end surface, and the horizontal frame side end surface of the ridge, and the upper ridge portion and the lower ridge portion are fitted together, the frame periphery If the frame material is made of solid wood, the upper ridge will expand and contract due to fluctuations in the moisture content of the wooden material, An upward warp is generated, and a gap, a step or the like is easily generated between the members across the joint groove.

また、上記、特開平５−７１２７２号公報に記載の木製ドアの製造方法では、芯材の表裏面に表面化粧板を接着剤で接着して縦框及び横框を形成し、該縦框及び横框の内周部に芯材の一部を突出させ鏡板が填め込まれている額縁で、前記芯材の突出部を表裏面から挟持させ、接着剤で接着し、前記縦框及び横框の内周部に前記額縁を取り付けているが、その際の接着剤の塗布量を厳密に管理しないで塗布量にバラツキがでると、余剰の接着剤が接合部から溢れ出すことがあり、仕上がり外観上大変見苦しいものとなるといった問題があった。   Moreover, in the manufacturing method of the wooden door described in the above-mentioned Japanese Patent Application Laid-Open No. 5-71272, the surface decorative board is bonded to the front and back surfaces of the core material with an adhesive to form a vertical gutter and a horizontal gutter. With a frame in which a part of the core material protrudes from the inner peripheral part of the horizontal rail and the end plate is inserted, the protruding portion of the core material is sandwiched from the front and back surfaces and bonded with an adhesive. The frame is attached to the inner periphery of the adhesive, but if the coating amount varies without strictly controlling the amount of adhesive applied at that time, excess adhesive may overflow from the joint, resulting in a finish. There was a problem that it was very unsightly in appearance.

本発明は、上述した事情に鑑みてなされたもので、本発明の目的は、縦框、横框と額縁との間の目地溝、及び、縦框、横框の間の目地溝を形成する際、目地底部に塗装処理等のあと処理が不要で、製造作業性が極めて良好で、しかも熟練工も不要で、さらに、木質部材の含水率変動による部材伸縮や切欠加工精度不良、組み付け加工精度の多少の不良を吸収し、前記薄板部の先端部と額縁との間に、目隙、段差等が発生しにくく、仕上がり精度と外観的にも優れた額縁構造の戸板を安価に提供することを目的とする。さらに、本発明の他の目的は、芯材と表面化粧板との接合部や縦框及び横框と額縁との接合部から、余剰の接着剤が溢れ出すことを防止でき、仕上がり外観的にも優れた額縁構造の戸板を安価に提供することを目的とする。   This invention is made | formed in view of the situation mentioned above, The objective of this invention forms the joint groove between a downspout, a recumbent and a frame, and the joint groove between a downspout and a recumbent At the same time, post-processing such as painting processing is unnecessary on the joint base, manufacturing workability is extremely good, and skilled workers are also unnecessary.In addition, due to fluctuations in the moisture content of wooden members, member expansion and contraction accuracy is poor, assembly processing accuracy is low To provide a frame structure door plate that absorbs some defects, is less likely to cause gaps, steps, etc. between the tip of the thin plate portion and the frame, and has excellent finishing accuracy and appearance. Objective. Furthermore, another object of the present invention is to prevent excess adhesive from overflowing from the joint between the core material and the surface decorative board, and the joint between the vertical gutter and the horizontal gutter and the frame, in terms of the finished appearance. The purpose is to provide a door frame with an excellent frame structure at low cost.

上記の目的を達成するためになされた請求項１に記載の額縁構造戸板は、矩形形状の芯材１の表裏面に、表面化粧板２、３が接着されて、縦框４及び横框５が形成され、該縦框４及び横框５の内周部に前記芯材の一部を突出させ、鏡板８が填め込まれている額縁９で、前記芯材の突出部ＳＴを表裏面から挟持し接着剤で接着し、前記縦框４及び横框５の内周部に前記額縁９を取り付けて構成された額縁構造戸板であって、前記額縁９は、前記縦框４及び横框５側の端面の表面側に、額縁９の長手方向の全長にわたって、切欠段部Ｄ２が形成され、該切欠段部Ｄ２によって薄板部が形成され、該薄板部によって第２の下側突条部Ｔ２が形成されており、該第２の下側突条部Ｔ２によって、前記額縁９の外周の全周に沿うように、凹条溝Ｊ１が形成されており、さらに、前記横框５は、前記縦框４側の端面の表面側に、横框端面の全長にわたって、切欠段部Ｄ１２が形成され、該切欠段部Ｄ１２によって薄板部が形成され、該薄板部によって、第２の下側突条部Ｔ１２が形成されており、該第２の下側突条部Ｔ１２によって、前記横框５の短手方向の端面の縦框４側に凹条溝Ｊ２が形成されていることを特徴としている。   In order to achieve the above object, the frame structure door plate according to claim 1, wherein the front decorative plates 2 and 3 are bonded to the front and back surfaces of the rectangular core material 1, and the vertical gutter 4 and the horizontal gutter 5 are provided. Is formed, and a part of the core material is protruded from the inner peripheral portions of the vertical and horizontal ridges 4 and 5, and the protruding portion ST of the core material is formed from the front and back surfaces with the frame 9 in which the end plate 8 is fitted. A frame-structured door plate constructed by sandwiching and adhering with an adhesive and attaching the frame 9 to the inner periphery of the vertical gutter 4 and the horizontal gutter 5, wherein the frame 9 includes the vertical gutter 4 and the horizontal gutter 5 A notch step D2 is formed over the entire length in the longitudinal direction of the frame 9 on the surface side of the side end face, and a thin plate portion is formed by the notch step portion D2, and the second lower protrusion T2 is formed by the thin plate portion. And the concave groove J1 is formed along the entire outer periphery of the frame 9 by the second lower protrusion T2. Further, in the horizontal bar 5, a notch step portion D 12 is formed on the surface side of the end surface on the vertical rod 4 side over the entire length of the horizontal bar end surface, and a thin plate portion is formed by the notch step portion D 12. A second lower ridge T12 is formed by the thin plate portion, and the second lower ridge T12 is recessed on the vertical ridge 4 side of the end surface in the short direction of the horizontal ridge 5. A feature is that the groove J2 is formed.

このような構成を有する本発明によれば、凹条溝の目地底部として露出するのは、額縁に設けた第２の下側突条部と、横框の縦框側の端面、すなわち横框の短手側端面における表面化粧板の基材のみである。従って、表面化粧板の基材として通常用いられる合板や中比重繊維板が露出する部分は横框の左右短手部分の端面のみであり、ほとんど問題にならない。通常額縁は、品質、色調等の均一で外観上の欠点のない銘木の無垢材かまたは合成樹脂成型体からなるものが用いられるので、額縁を切欠して形成された目地底部は、前記したような目地底部の欠点や品質、色調のバラツキによる外観仕上がり性の低下といった問題点が解消される。ただ、横框の短手方向の下側突条部が目地溝底部となって、外観上露出するが、これは、戸板全体から見て、目地溝として短く、与える影響はほとんどない。   According to the present invention having such a configuration, what is exposed as the joint bottom portion of the groove is the second lower protrusion provided on the frame and the end surface of the downside of the downside, i.e., downside. It is only the base material of the surface decorative board in the short side end surface. Accordingly, the portion of the plywood or medium specific gravity fiber board that is normally used as the base material of the decorative face plate is exposed only at the end surfaces of the laterally short side portions of the reed, so that there is almost no problem. Usually, the frame is made of solid wood or synthetic resin molding that is uniform in quality, color tone, etc. and has no defects in appearance, so the joint base formed by cutting out the frame is as described above. This eliminates the problems such as defects in the bottom of the joint, quality, and deterioration in the appearance finish due to variations in color tone. However, the lower ridge in the lateral direction of the recumbent becomes the joint groove bottom and is exposed in appearance, but this is short as a joint groove when viewed from the whole door plate, and has little effect.

また、その箇所においても目地底部の仕上がりを考慮して、その箇所のみ塗装処理すれば済む。戸板全体からして、小部分ゆえかかる手間も小さくて済む。また、係る箇所の基材のみ欠点や木繊維の方向性の無い中比重繊維板等を使用すれば、仕上がりは全く問題なく、しかも横框の面積は比較的小さいので、コストに与える影響も極めて小さい。このようにして、仕上がり精度と外観的にも優れた額縁構造の戸板を安価に提供することができる。   In addition, it is only necessary to perform the coating process only in that portion in consideration of the finish of the joint bottom. Since the entire door plate is small, the labor required is small. In addition, if a medium specific gravity fiber board or the like having no defects or wood fiber directionality is used only for the base material in such a place, the finish will be no problem at all, and the area of the reed is relatively small, so the impact on the cost is also extremely high small. In this way, a door plate having a frame structure with excellent finishing accuracy and appearance can be provided at low cost.

請求項２に記載の額縁構造戸板は、請求項１に記載の額縁構造戸板において、前記縦框４及び横框５の表面化粧板２、３の額縁側の端面の裏面側に、縦框４及び横框５の長手方向の全長にわたって、切欠段部Ｄ１が形成され、該切欠段部Ｄ１によって薄板部が形成され、該薄板部によって、第１の上側突条部Ｔ１が形成され、芯材との間に嵌合凹部が形成されており、さらに、前記縦框４の表面化粧板２の横框５側の端面の裏面側に、縦框４の長手方向に、切欠段部Ｄ１１が形成され、該切欠段部Ｄ１１によって薄板部が形成され、該薄板部によって、第１の上側突条部Ｔ１１が形成され、前記第１の上側突条部Ｔ１、Ｔ１１と前記第２の下側突条部Ｔ２、Ｔ１２とが、相じゃくり方式で、相互に嵌合し、該嵌合箇所に、凹条溝Ｊ１、Ｊ２が形成されていることを特徴としている。   The frame-structure door board according to claim 2 is the frame-structure door board according to claim 1, wherein the vertical frame 4 is provided on the back side of the frame-side end surface of the surface decorative plates 2, 3 of the vertical wall 4 and the horizontal wall 5. A cut-out step portion D1 is formed over the entire length of the horizontal bar 5 in the longitudinal direction, a thin plate portion is formed by the cut-out step portion D1, and a first upper ridge portion T1 is formed by the thin plate portion. And a notch step portion D11 is formed in the longitudinal direction of the vertical rod 4 on the back side of the end surface of the vertical decorative plate 2 on the horizontal surface 5 side. A thin plate portion is formed by the notch step portion D11, and a first upper ridge portion T11 is formed by the thin plate portion, and the first upper ridge portions T1 and T11 and the second lower ridge portion are formed. The strips T2 and T12 are mated with each other in a phased manner, and concave grooves J1 and J2 are formed at the mating locations. It is characterized in that have been made.

このような構成を有する本発明によれば、額縁部材として例えば天然銘木からなる木材無垢を用いても、上側突条部が、縦框の額縁側端面及び横框側端面に形成され、また、横框の額縁側端面に形成されるので、上側突条部は、縦框、横框の化粧板で構成されることになり、相じゃくり嵌合で上側突条部が下側突条部を押さえ込み、木材の含水率変動による伸縮に弱い木材無垢からなる下側突条部の変形を有効に防止できる。すなわち、縦框、横框の化粧板は合板または中比重繊維板等を基材とし、木材無垢を基材としないので、上側突条部は、含水率変動に対して安定したものとなり、目地溝（凹条溝）を挟んでの目隙や段差にとって安定したものとなる。すなわち、木質部材の含水率変動による部材伸縮や切欠加工精度不良、組み付け加工精度の多少の不良を有効に吸収し、前記薄板部の先端部と額縁との間に、目隙、段差等が発生しにくくなり、外観的にも優れた額縁構造の戸板が可能となる。   According to the present invention having such a configuration, the upper ridges are formed on the frame-side end surface and the recumbent-side end surface of the vertical fence, even when using pure wood made of natural wood, for example, as the frame member, Since it is formed on the frame-side end face of the recumbent frame, the upper ridge is composed of a vertical and horizontal decorative panel. It is possible to effectively prevent deformation of the lower ridge portion made of solid wood that is vulnerable to expansion and contraction due to fluctuations in the moisture content of the wood. In other words, because the vertical and horizontal decorative panels are made of plywood or medium specific gravity fiber board and not solid wood, the upper ridge is stable against fluctuations in moisture content. It is stable for gaps and steps across the ground groove (concave groove). That is, it effectively absorbs material expansion / contraction, notch processing accuracy failure and some assembly accuracy due to fluctuations in moisture content of wood members, and gaps, steps, etc. occur between the tip of the thin plate and the frame. This makes it possible to produce a doorboard with a frame structure that is excellent in appearance.

請求項３に記載の額縁構造戸板は、請求項１または請求項２に記載の額縁構造戸板において、前記第２の下側突条部Ｔ２、Ｔ１２の突出長さが、前記第１の上側突条部Ｔ１、Ｔ１１の突出長さよりも長く、前記下側突条部Ｔ２、Ｔ１２の先端面Ｓ２、Ｓ１２と前記嵌合凹部の奥底面Ｓ１、Ｓ１１とが当接し、該嵌合箇所に、前記第１の上側突条部Ｔ１、Ｔ１１と前記第２の下側突条部Ｔ２、Ｔ１２の突出長さ寸法差を溝幅とする凹条溝Ｊ１、Ｊ２が形成されていることを特徴としている。   The frame structure door plate according to claim 3 is the frame structure door plate according to claim 1 or 2, wherein a protrusion length of the second lower protrusions T2 and T12 is the first upper protrusion. Longer than the projecting length of the strips T1, T11, the front end surfaces S2, S12 of the lower projecting strips T2, T12 and the back bottom surfaces S1, S11 of the fitting recess come into contact with each other, Concave grooves J1 and J2 having a groove width defined by the projecting length dimension difference between the first upper protrusions T1 and T11 and the second lower protrusions T2 and T12 are formed. .

このような構成を有する本発明によれば、前記第２の下側突条部Ｔ２、Ｔ１２の突出長さが、前記第１の上側突条部Ｔ１、Ｔ１１の突出長さよりも長く、前記下側突条部Ｔ２、Ｔ１２の先端面Ｓ２、Ｓ１２と前記嵌合凹部の奥底面Ｓ１、Ｓ１１とが当接し、該嵌合箇所に、前記第１の上側突条部Ｔ１、Ｔ１１と前記第２の下側突条部Ｔ２、Ｔ１２の突出長さ寸法差による凹条溝Ｊ１、Ｊ２が形成されるようにしたので、前記凹条溝Ｊ１、Ｊ２の溝幅寸法が一定となり、溝幅のバラツキが有効に防止可能となり、仕上がり精度に優れた額縁構造戸板が可能となる。   According to the present invention having such a configuration, the protrusion length of the second lower protrusions T2, T12 is longer than the protrusion length of the first upper protrusions T1, T11, and the lower protrusion The front end surfaces S2 and S12 of the side ridge portions T2 and T12 and the inner bottom surfaces S1 and S11 of the fitting recess come into contact with each other, and the first upper ridge portions T1 and T11 and the second upper portion at the fitting portions. Since the groove grooves J1 and J2 are formed by the difference in projecting length of the lower protrusions T2 and T12, the groove width dimension of the groove grooves J1 and J2 is constant, and the groove width varies. Can be effectively prevented, and a frame-structured door plate with excellent finish accuracy is possible.

請求項４に記載の額縁構造戸板は、請求項１〜３のいずれかに記載の額縁構造戸板において、前記嵌合凹部の奥底面Ｓ１、Ｓ１１と前記第２の下側突条部Ｔ２、Ｔ１２の先端面Ｓ２、Ｓ１２との間に隙間が形成され、該隙間によって接着剤溜まり凹部Ｕが形成されていることを特徴としている。   The frame structure door plate according to claim 4 is the frame structure door plate according to any one of claims 1 to 3, wherein the bottom surfaces S1 and S11 of the fitting recess and the second lower protrusions T2 and T12 are provided. A gap is formed between the tip surfaces S2 and S12, and an adhesive reservoir recess U is formed by the gap.

このような構成を有する本発明によれば、前記第１の上側突条部と芯材とで形成されている嵌合凹部の奥底面と前記第２の下側突条部の先端面との間に隙間が形成されているので、芯材の表裏面に表面化粧板を接着し、また、縦框及び横框の内周部からその一部を突出している芯材の突出部に額縁を接着したとき、接着剤の塗布量が多少多めになっていても、余剰の接着剤はこの接着剤溜まり凹部に溜まり、接着剤が縦框と横框との端部の接合部や縦框及び横框の内周部と額縁の接合部から溢れ出すことを防止することができ、仕上がり外観の優れた高品質の額縁構造戸板を得ることができる。従って、接着剤の塗布量管理範囲が広く設定でき製造作業性に優れる。   According to the present invention having such a configuration, the inner bottom surface of the fitting recess formed by the first upper ridge portion and the core material and the tip surface of the second lower ridge portion A gap is formed between the front and back surfaces of the core material, and a frame is attached to the protruding portion of the core material that protrudes partly from the inner periphery of the vertical and horizontal ribs. Even when the amount of adhesive applied is slightly larger when bonded, the excess adhesive will remain in the adhesive reservoir recess, and the adhesive will remain at the junction between the vertical and horizontal ends, It is possible to prevent overflowing from the joint between the inner peripheral portion of the side wall and the frame, and it is possible to obtain a high-quality frame structure door plate having an excellent finished appearance. Therefore, the application amount management range of the adhesive can be set wide and the manufacturing workability is excellent.

請求項１の発明によれば、目地底部として露出するのは、額縁に設けた第２の下側突条部と、横框の縦框側の端面、すなわち横框の短手側端面における表面化粧板の基材のみである。従って、表面化粧板の基材として通常用いられる合板や中比重繊維板が露出する部分は横框の左右短手部分の端面のみであり、ほとんど問題とならない。通常額縁は、品質、色調等の均一で外観上の欠点のない銘木の無垢材か、又は合成樹脂成型体からなるものが用いられるので、額縁を切欠して得られた目地溝の目地底部は前記したような目地底部の欠点や品質、色調のバラツキによる外観仕上がり性の低下といった問題点が解消される。ただ、前記したように、横框の短手方向の下側突条部が目地溝底部となって、外観上露出するが、これは、戸板全体から見て、目地溝として短く、与える影響はほとんどない。   According to the first aspect of the present invention, the second lower protrusion provided on the frame and the surface on the side surface of the downside of the downside, that is, the side surface of the short side of the side surface are exposed as the joint bottom. Only the base material of the decorative board. Therefore, the portion where the plywood or medium specific gravity fiber board, which is usually used as the base material of the surface decorative board, is exposed only on the end surfaces of the right and left short sides of the reed, and hardly causes a problem. Normally, the frame is made of solid wood with uniform quality, color tone, etc. and no defects in appearance, or one made of a synthetic resin molding, so the joint bottom of the joint groove obtained by cutting out the frame is The problems such as the above-described defects in the joint bottom, quality, and deterioration in the appearance finish due to variations in color tone are solved. However, as described above, the lower ridge of the lateral direction of the recumbent portion becomes the bottom of the joint groove, and is exposed on the appearance. rare.

また、その箇所においても目地底部の仕上がりを考慮して、その箇所のみ塗装処理すれば済む。戸板全体からして、小部分ゆえかかる手間も小さくて済む。また、係る箇所の基材のみ欠点や木繊維の方向性の無い中比重繊維板等を使用すれば、仕上がりは全く問題なく、しかも横框は比較的小面積ゆえ、コストに与える影響も極めて小さい。このようにして、仕上がり精度と外観的にも優れた額縁構造の戸板を安価に提供することができる。   In addition, it is only necessary to perform the coating process only in that portion in consideration of the finish of the joint bottom. Since the entire door plate is small, the labor required is small. In addition, if a medium specific gravity fiber board or the like having no defects or wood fiber directionality is used only for the base material in such a place, the finish will be no problem at all, and since the reed is relatively small in area, the impact on the cost will be extremely small . In this way, a door plate having a frame structure with excellent finishing accuracy and appearance can be provided at low cost.

請求項２の発明によれば、前記第１の上側突条部Ｔ１、Ｔ１１と前記第２の下側突条部Ｔ２、Ｔ１２とが、相じゃくり方式で、相互に嵌合し、該嵌合箇所に、凹条溝Ｊ１、Ｊ２が形成されているようにしたので、木質部材の含水率変動による部材伸縮や切欠加工精度不良、組み付け加工精度の多少の不良を有効に吸収し、前記薄板部の先端部と額縁との間に、目隙等が発生しにくく、外観的にも優れた額縁構造の戸板が可能となる。   According to the invention of claim 2, the first upper ridge portions T1, T11 and the second lower ridge portions T2, T12 are fitted to each other in a phased manner, and the fitting is performed. Since the concave grooves J1 and J2 are formed at the joints, the thin plate effectively absorbs the member expansion / contraction, the notch processing accuracy defect, and the assembly processing accuracy defect due to the moisture content variation of the wooden member. A door plate having a frame structure that is less likely to cause a gap or the like between the front end portion of the portion and the frame, and that has an excellent appearance.

すなわち、額縁部材として例えば天然銘木からなる木材無垢を用いても、上側突条部が、縦框の額縁側端面及び横框側端面に形成され、また、横框の額縁側端面に形成されるので、上側突条部は、縦框、横框の化粧板で構成されることになり、相じゃくり嵌合で上側突条部が下側突条部を押さえ込み、木材の含水率変動による伸縮に弱い木材無垢からなる下側突条部の変形を有効に防止できる。すなわち、縦框、横框の化粧板は合板または中比重繊維板等を基材とし、木材無垢を基材としないので、上側突条部は、含水率変動に対して安定したものとなり、目地溝（凹条溝）を挟んでの目隙や段差にとって安定したものとなる。すなわち、木質部材の含水率変動による部材伸縮や切欠加工精度不良、組み付け加工精度の多少の不良を有効に吸収し、前記薄板部の先端部と額縁との間に、目隙、段差等が発生しにくくなり、外観的にも優れた額縁構造の戸板が可能となる。   That is, for example, even when solid wood made of natural wood is used as the frame member, the upper protrusions are formed on the frame-side end surface and the recumbent-side end surface of the downpipe, and are formed on the frame-side end surface of the recumbent frame. Therefore, the upper ridge is composed of vertical and horizontal decorative panels, and the upper ridge presses down the lower ridge in a labyrinth fitting, and the expansion and contraction is caused by fluctuations in the moisture content of the wood. It is possible to effectively prevent the deformation of the lower ridge portion made of solid wood that is not easily damaged. In other words, because the vertical and horizontal decorative panels are made of plywood or medium specific gravity fiber board and not solid wood, the upper ridge is stable against fluctuations in moisture content. It is stable for gaps and steps across the ground groove (concave groove). That is, it effectively absorbs material expansion / contraction, notch processing accuracy failure and some assembly accuracy due to fluctuations in moisture content of wood members, and gaps, steps, etc. occur between the tip of the thin plate and the frame. This makes it possible to produce a doorboard with a frame structure that is excellent in appearance.

The front end surfaces S2 and S12 of the portions T2 and T12 and the inner bottom surfaces S1 and S11 of the fitting recess come into contact with each other, and the first upper protrusions T1 and T11 and the second lower side at the fitting portion Since the groove grooves J1 and J2 having the protrusion length dimension difference between the protrusions T2 and T12 as the groove width are formed, the groove width dimension of the groove grooves J1 and J2 becomes constant, and the groove width Variations can be effectively prevented, and a frame-structured doorboard with excellent finish accuracy is possible.

請求項４の発明によれば、前記嵌合凹部の奥底面Ｓ１、Ｓ１１と前記第２の下側突条部Ｔ２、Ｔ１２の先端面Ｓ２、Ｓ１２との間に隙間が形成され、該隙間によって接着剤溜まり凹部Ｕが形成されているので、芯材の表裏面に表面化粧板を接着し、また、縦框４及び横框５の内周部からその一部を突出している芯材の突出部ＳＴに額縁９を接着したとき、接着剤の塗布量が多少多めになっていても、余剰の接着剤はこの接着剤溜まり凹部Ｕに溜まり、接着剤が縦框４と横框５との端部の接合部や縦框４及び横框５の内周部と額縁９の接合部から溢れ出すことを有効に防止することができ、仕上がり外観の優れた高品質の額縁構造戸板を得ることができる。従って、接着剤の塗布量管理範囲が広く設定でき、製造作業性に優れる。   According to invention of Claim 4, a clearance gap is formed between back bottom face S1, S11 of the said fitting recessed part, and front-end | tip surface S2, S12 of said 2nd lower side protrusion part T2, T12, By this clearance gap Since the adhesive reservoir recessed portion U is formed, the surface decorative plate is bonded to the front and back surfaces of the core material, and the core material projecting partly from the inner peripheral portion of the vertical rod 4 and the horizontal rod 5 When the frame 9 is bonded to the part ST, even if the applied amount of the adhesive is slightly larger, the excess adhesive remains in the adhesive reservoir recess U, and the adhesive is between the vertical hook 4 and the horizontal hook 5.
