Description

本発明は、水平片と立設片とを有しており、円弧状に屈曲させてある形材及びこれを用いた開口部ユニットに関する。   The present invention relates to a shape member having a horizontal piece and a standing piece and bent in an arc shape and an opening unit using the same.

水平片１０１と立設片１０２からなる断面略Ｌ字形の形材を円弧状に屈曲させる場合、図９に示すように、屈曲部分の水平片１０１に複数のくさび形の切欠１０３を形成し（図９（ａ））、各切欠１０３を内側にたたむようにして立設片１０２を屈曲させる方法があった（図９（ｂ））。しかし、滑らかな円弧状にするために多数の切欠を形成すると、その分だけ水平片に多数の切込の跡が残るので外観が悪い点が問題であった。そこで、特許文献１には、水平片に三角形状の第一切除部と円弧状辺を有する第二切除部とを形成し、立設片を円弧状辺に沿って屈曲させる方法が提案されている。この方法によれば、水平片の切込跡は一本のみとなる。   When a substantially L-shaped section consisting of the horizontal piece 101 and the standing piece 102 is bent in an arc shape, a plurality of wedge-shaped notches 103 are formed in the horizontal piece 101 at the bent portion (see FIG. 9). In FIG. 9A, there is a method of bending the standing piece 102 so that each notch 103 is folded inward (FIG. 9B). However, if a large number of notches are formed in order to form a smooth arc, a large number of notch marks remain on the horizontal piece, and the appearance is poor. Therefore, Patent Document 1 proposes a method in which a first cut portion having a triangular shape and a second cut portion having an arcuate side are formed in a horizontal piece, and the standing piece is bent along the arcuate side. Yes. According to this method, the horizontal piece has only one cut mark.

特開昭６３−１１２０２６号公報JP-A-63-112026

しかしながら、上記の方法による場合、水平片の切込跡は少ないものの、屈曲部分において立設片を円弧状辺に沿わせる構成上、立設片と水平片の間の隙間が目立ってしまう点が問題である。   However, in the case of the above method, although there are few cuts of the horizontal piece, there is a point that the gap between the standing piece and the horizontal piece becomes conspicuous because of the configuration in which the standing piece follows the arcuate side at the bent portion. It is a problem.

本発明は、上記事情を鑑みたものであり、水平片と立設片とを有しており、円弧状に屈曲させてあるものであって、外観が良好な形材及びこれを用いた開口部ユニットを提供することを目的とする。   The present invention has been made in view of the above circumstances, has a horizontal piece and a standing piece, is bent in an arc shape, and has a good appearance and an opening using the same. The purpose is to provide departmental units.

本発明のうち請求項１の発明は、水平片と、水平片の一方側端から上方に延びる立設片とを有し、水平片と立設片とが交わる角部を所定長さにわたり切り取った切取部と、切取部の中央から水平片の他方側に寄った点を頂点とし、水平片の他方側端を底辺とする略二等辺三角形状の第一切欠部と、第一切欠部の頂点から切取部まで連通する第二切欠部とを形成してあり、水平片の一方側端を立設片の下側に入り込ませつつ、第一切欠部の対向する辺同士が当接する位置まで立設片を円弧状に屈曲させてあることを特徴とする。   The invention of claim 1 of the present invention has a horizontal piece and a standing piece extending upward from one end of the horizontal piece, and cuts a corner portion where the horizontal piece and the standing piece intersect over a predetermined length. A cut-out portion, a first isometric triangle-shaped notch with a point near the other side of the horizontal piece from the center of the cut-out portion and a bottom of the other end of the horizontal piece, A second cutout portion that communicates from the top of the cut portion to the cutout portion is formed, and the opposite sides of the first cutout portion contact each other while the one end of the horizontal piece enters the lower side of the standing piece. The standing piece is bent in an arc shape to a position where it comes into contact.

本発明のうち請求項２の発明は、立設片の上端から一方側に延びる上部片を有し、上部片が、複数の構成部材を他方側から一方側に向けて連設したものであって、隣接する構成部材同士が、長手方向にスライド自在に嵌合していることを特徴とする。   The invention according to claim 2 of the present invention has an upper piece extending from the upper end of the standing piece to one side, and the upper piece is formed by connecting a plurality of constituent members from the other side to the one side. Adjacent constituent members are slidably fitted in the longitudinal direction.

本発明のうち請求項３の発明は、開口部に取り付けるものであって、外枠と、内蓋とを有しており、外枠が、請求項１又は２記載の形材からなり、開口部の形状に合わせて屈曲させてあって、一方側が開口部の外周側、他方側が開口部の内周側を向くように、開口部の周縁部に取り付けてあり、内蓋が、略平板形状で、外枠の水平片に係止していることを特徴とする。   The invention according to claim 3 of the present invention is attached to the opening, and has an outer frame and an inner lid, and the outer frame is made of the profile according to claim 1 or 2, and is opened. It is bent according to the shape of the part, and is attached to the peripheral part of the opening part so that one side faces the outer peripheral side of the opening part and the other side faces the inner peripheral side of the opening part. And it is latching to the horizontal piece of an outer frame, It is characterized by the above-mentioned.

本発明のうち請求項１の発明によれば、屈曲部分において水平片が立設片の下側に入り込むので、上側から隙間が見えにくい。また、円弧状に屈曲させるにもかかわらず、直線状の切断加工のみで構成されるので、曲率の変更にも容易に対応できる。   According to the first aspect of the present invention, since the horizontal piece enters the lower side of the standing piece at the bent portion, it is difficult to see the gap from the upper side. Moreover, since it is comprised only by the linear cutting process, it can respond easily to the change of a curvature, although making it bend in circular arc shape.

また、立設片の上端から一方側に延びる上部片を設けた場合、屈曲部分の上部片は一方側が円弧の外周側となるので、一方側にいくほど曲げ応力が増大して曲げ加工が困難になるが、本発明のうち請求項２の発明によれば、上部片を複数の構成部材に分割してあるので、曲げ応力の増大が構成部材同士の滑りに置き換えられ、容易に曲げ加工を行うことができる。   In addition, when an upper piece extending from the upper end of the erected piece to one side is provided, the upper piece of the bent portion has one side on the outer peripheral side of the arc, so that bending stress increases toward the one side, making bending difficult. However, according to the invention of claim 2 of the present invention, since the upper piece is divided into a plurality of constituent members, the increase in bending stress is replaced by the slip between the constituent members, and bending can be easily performed. It can be carried out.

本発明のうち請求項３の発明によれば、外枠の屈曲部において隙間が見えにくく、外観が良好な開口部ユニットとなる。また、上部片を複数の構成部材に分割したことにより、上部片を大きくすることが可能であり、開口部の角部が円弧状でない場合でも、覆い隠すことができる。さらに、外枠の角部を円弧状に屈曲させてあり、それに合わせて内蓋の角部も円弧状に形成できるので、接触しても安全である。   According to the invention of claim 3 among the present invention, it is difficult to see the gap at the bent portion of the outer frame, and the opening unit has a good appearance. Further, by dividing the upper piece into a plurality of constituent members, the upper piece can be enlarged, and even when the corner of the opening is not arcuate, it can be covered. Furthermore, the corners of the outer frame are bent in an arc shape, and the corners of the inner lid can be formed in an arc shape accordingly, so that it is safe to contact.

以下、本発明の実施の形態を図面に基づいて説明する。この形材の第一実施形態は、図１に示すように、水平片１と、水平片１の一方側端から垂直上方に延びる立設片２とを有し、さらに水平片１の他方側端から垂直下方に延びる垂下片７と、立設片２の上端から一方側に延びる上部片８とを有する。水平片１、立設片２及び垂下片７は同一かつ一定の厚さであり、上部片８は基端から先端に向けて徐々に薄くなっている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the first embodiment of the shape member has a horizontal piece 1 and a standing piece 2 extending vertically upward from one end of the horizontal piece 1, and the other side of the horizontal piece 1. A hanging piece 7 extending vertically downward from the end and an upper piece 8 extending from the upper end of the standing piece 2 to one side are provided. The horizontal piece 1, the standing piece 2, and the hanging piece 7 have the same and constant thickness, and the upper piece 8 gradually decreases from the base end toward the tip.

そして、この形材を他方側を内側にして屈曲させるために、切断加工を施して、切取部４、第一切欠部５及び第二切欠部６を形成してある。切取部４は、水平片１と立設片２とが交わる角部３を所定の長さにわたり切り取って形成したもので、当該範囲においては水平片１と立設片２とが分断されている。切取部４の範囲は、すなわち立設片２が屈曲する範囲であり、切取部４を長くすれば屈曲部分の曲率は小さくなり、切取部４を短くすれば屈曲部分の曲率は大きくなる。第一切欠部５は、水平片１に形成した切欠であり、切取部４の中央から水平片１の他方側に寄った点を頂点とし、水平片１の他方側端を底辺とする二等辺三角形状である。二等辺三角形の頂角θは、形材の屈曲角と等しく、本実施形態では９０度である。なお、水平片１に連続する垂下片７も、水平片１と合わせて切り欠いてある。第二切欠部６も、同じく水平片１に形成した切欠であり、第一切欠部５の頂点から切取部４の中心まで連通する直線形状である。よって、第一切欠部５及び第二切欠部６により、水平片１は分断される。   Then, in order to bend the shape member with the other side inward, the cut portion 4, the first notch portion 5 and the second notch portion 6 are formed by cutting. The cut portion 4 is formed by cutting a corner portion 3 where the horizontal piece 1 and the standing piece 2 cross each other over a predetermined length, and the horizontal piece 1 and the standing piece 2 are divided in this range. . The range of the cut portion 4 is a range in which the standing piece 2 is bent. If the cut portion 4 is lengthened, the curvature of the bent portion is reduced, and if the cut portion 4 is shortened, the curvature of the bent portion is increased. The second notch 5 is a notch formed in the horizontal piece 1, with the point nearing the other side of the horizontal piece 1 from the center of the cutout 4 as the apex and the other end of the horizontal piece 1 as the bottom. It is an equilateral triangle. The apex angle θ of the isosceles triangle is equal to the bending angle of the profile, and is 90 degrees in the present embodiment. In addition, the drooping piece 7 continuing to the horizontal piece 1 is also cut out together with the horizontal piece 1. The second notch 6 is also a notch formed in the horizontal piece 1 and has a linear shape communicating from the top of the first notch 5 to the center of the cutout 4. Therefore, the horizontal piece 1 is divided by the first notch 5 and the second notch 6.

このように形成した形材を屈曲させる際には、水平片１の一方側端の、切取部４によって立設片２と分断された部分（端部片１ａ，１ｂ）を、立設片２の下側に入り込ませつつ、第一切欠部５の対向する辺（対向辺５ａ，５ｂ）同士が当接する位置まで、立設片２を円弧状に屈曲させる（図１（ｄ）、図２）。この際、上部片８については引き伸ばし加工をすることになるが、上部片８は、引き伸ばし量が大きくなる先端側に向けて薄くなっているので、容易に引き伸ばすことができる。   When the shape member formed in this way is bent, the part (end piece 1a, 1b) of one side end of the horizontal piece 1 separated from the standing piece 2 by the cutout portion 4 is used as the standing piece 2. The standing piece 2 is bent in a circular arc shape until the opposite sides (opposing sides 5a, 5b) of the first notch 5 come into contact with each other (FIG. 1 (d), FIG. 2). At this time, the upper piece 8 is stretched. However, since the upper piece 8 is thinned toward the tip side where the amount of stretching is increased, it can be easily stretched.

なお、形材を屈曲させる具体的な手段の一例として、図３に示すように、上型１１と下型１２とで形材Ｐ１を挟み込む方法がある。以下、本段落において、手前側、奥側及び左右側とは、図３（ａ）における手前側、奥側及び左右側を示すものとする。上型１１は、形材Ｐ１の立設片２の屈曲部分の曲率と等しい曲率で下向きに凸な湾曲部１１ａと、湾曲部１１ａの手前側に設けられ湾曲部１１ａより下側に突出する突出部１１ｂとを有する。一方、下型１２は左右に二つ配置され、互いに対称な形状をしており、手前側の低段部１２ａと、奥側の高段部１２ｂを有していて、さらに低段部１２ａ及び高段部１２ｂの左右内側には、形材の屈曲角に対応した傾斜部１２ｃ，１２ｄが形成されている。また、左右の下型１２の間には、ダイクッション１３を設けてあり、ダイクッション１３は弾性部材１３ａにより支持してある。形材Ｐ１は、手前側が上部片８、奥側が垂下片７となる向きで、立設片２が低段部１２ａに、垂下片７が高段部１２ｂに載るようにして、下型１２に載置する。第一切欠部５及び第二切欠部６は、左右の下型１２の中央に位置させる。そして、形材Ｐ１の上方から上型１１を降下させ、湾曲部１１ａを立設片２に当接させて押し曲げる。すると、形材Ｐ１はダイクッション１３により弾性的に支持されながら、立設片２が湾曲部１１ａにそって円弧状に屈曲する。この際、上部片８は突出部１１ｂに沿って滑らかに変形する。そしてそれと同時に、水平片１の端部片１ａ，１ｂが立設片２の奥側（図１では下側）に入り込む。低段部１２ａ及び高段部１２ｂに支持されていた立設片２及び垂下片７は、形材Ｐ１の屈曲に伴って傾斜部１２ｃ，１２ｄに移行する。そして、形材Ｐ１は第一切欠部５の対向辺５ａ，５ｂが当接する位置まで屈曲する（図３（ｃ））。   As an example of a specific means for bending the shape material, there is a method of sandwiching the shape material P1 between the upper die 11 and the lower die 12, as shown in FIG. Hereinafter, in this paragraph, the near side, the back side, and the left and right sides indicate the near side, the back side, and the left and right sides in FIG. The upper die 11 has a curved portion 11a that protrudes downward with a curvature equal to the curvature of the bent portion of the standing piece 2 of the profile P1, and a protrusion that is provided on the front side of the curved portion 11a and projects downward from the curved portion 11a. Part 11b. On the other hand, two lower molds 12 are arranged on the left and right sides, and are symmetrical to each other. The lower mold 12 has a lower step portion 12a on the front side and a higher step portion 12b on the rear side. Inclined portions 12c and 12d corresponding to the bending angle of the profile are formed on the left and right inner sides of the high step portion 12b. A die cushion 13 is provided between the left and right lower molds 12, and the die cushion 13 is supported by an elastic member 13a. The profile P1 is oriented so that the front side is the upper piece 8 and the back side is the hanging piece 7, the standing piece 2 is placed on the low step portion 12a, and the hanging piece 7 is placed on the high step portion 12b. Place. The first notch part 5 and the second notch part 6 are positioned at the center of the left and right lower molds 12. Then, the upper die 11 is lowered from above the shape member P1, and the bending portion 11a is brought into contact with the standing piece 2 and is bent. Then, while the shape member P1 is elastically supported by the die cushion 13, the standing piece 2 bends in an arc shape along the curved portion 11a. At this time, the upper piece 8 is smoothly deformed along the protruding portion 11b. At the same time, the end pieces 1a, 1b of the horizontal piece 1 enter the back side (lower side in FIG. 1) of the standing piece 2. The standing piece 2 and the hanging piece 7 supported by the low step portion 12a and the high step portion 12b shift to the inclined portions 12c and 12d as the shape member P1 is bent. Then, the profile P1 is bent to a position where the opposing sides 5a and 5b of the first notch 5 are in contact with each other (FIG. 3C).

このようにして屈曲させた形材は、水平片１の切込跡が第一切欠部５の対向辺５ａ，５ｂの当接部分の一本のみとなり、さらに屈曲部分において水平片１が立設片２の下側に入り込むので上側から隙間が見えにくく、外観が良好である。ただし、端部片１ａ，１ｂが立設片２の下側から一方側に飛び出しているので、上側からしか見えない箇所に使用することが望ましい。また、円弧状に屈曲させるにもかかわらず、直線状の切断加工のみで構成されており、切取部４の長さや第一切欠部５の頂点の位置を変更すれば、容易に屈曲部分の曲率を変更できる。   In the shape member bent in this way, the cut mark of the horizontal piece 1 is only one of the contact portions of the opposing sides 5a and 5b of the first notch 5, and the horizontal piece 1 stands at the bent portion. Since it enters into the lower side of the installation piece 2, it is hard to see a clearance | gap from upper side, and an external appearance is favorable. However, since the end pieces 1a and 1b protrude from the lower side of the standing piece 2 to the one side, it is desirable to use the end pieces 1a and 1b at a place that can be seen only from the upper side. Moreover, although it is made to be bent in an arc shape, it is configured only by a linear cutting process. If the length of the cutout portion 4 or the position of the apex of the first notch portion 5 is changed, the bent portion can be easily formed. The curvature can be changed.

次に、このようにして屈曲させた形材を開口部ユニットに用いた場合の例を示す。この開口部ユニットは、床下収納庫として用いるものであり、図４に示すように、床板２１に設けた略正方形の開口部２２に取り付けるものであって、外枠（形材Ｐ２）と、内蓋３０と、箱形の本体２３とを備えるものである（ただし、図４（ａ）は内蓋３０を外した状態を示す）。より詳しくは、図４（ｂ）に示すように、開口部２２の周囲には根太２４がまわしてあり、根太２４は大引き２５に載置してあり、さらに大引き２５は束２６によって支持してある。そして根太２４の開口部２２側には補助根太２７が取り付けてあり、補助根太２７に載置するようにして、開口部２２の周縁部に形材Ｐ２が取り付けてある。形材Ｐ２は、図１に示した形材と同様に、水平片１と、立設片２と、垂下片７と、上部片８とを有し、さらに垂下片７の下端から開口部２２側に延びる略Ｌ字形状の係止片９と、立設片２の下端から垂直下方に延びる脚部片１０とを有している。このような形材Ｐ２においても、垂下片７と係止片９を水平片１と合わせて切り欠いて第一切欠部を形成し、また水平片１と立設片２とを分断するように切取部及び第二切欠部を形成することで、図１に示した形材と同様に屈曲させることができる。そして長尺の形材Ｐ２を四か所で屈曲させて略正方形の外枠を形成して、上部片８が床板２１の上面に係止するようにして開口部２２の周縁部に嵌め込み、係止片９を補助根太２７にネジ止めして固定してある。このようにすると、形材Ｐ２の一方側が開口部２２の外周側、他方側が開口部２２の内周側を向く。また、本体２３は上方に開口した箱形で、開口縁部には略Ｌ字形状の爪部２３ａを有し、爪部２３ａを形材Ｐ２の係止片９に係止させて開口部２２に収めてある。そして水平片１には略平板形状の内蓋３０が載置される。外枠（形材Ｐ２）を円弧状に屈曲させたことにより、それに合わせて内蓋３０の角部も円弧状に形成できるので、接触しても安全である。なお、このように開口部ユニットを床下収納庫として用いる場合、開口部の周縁部に取り付けた形材は上側からしか見えないので、端部片が立設片の下側から飛び出している点は外観上問題とならない。   Next, an example in which the shape member bent in this manner is used for the opening unit will be described. This opening unit is used as an underfloor storage, and as shown in FIG. 4, is attached to a substantially square opening 22 provided on the floor plate 21, and includes an outer frame (shape member P <b> 2) and an inner frame. A lid 30 and a box-shaped main body 23 are provided (however, FIG. 4A shows a state in which the inner lid 30 is removed). More specifically, as shown in FIG. 4 (b), a joist 24 is turned around the opening 22, the joist 24 is placed on a large pull 25, and the large pull 25 is supported by a bundle 26. It is. An auxiliary joist 27 is attached to the joist 24 on the side of the opening 22, and a shape member P <b> 2 is attached to the peripheral portion of the opening 22 so as to be placed on the auxiliary joist 27. Similarly to the profile shown in FIG. 1, the profile P <b> 2 has a horizontal piece 1, a standing piece 2, a hanging piece 7, and an upper piece 8, and further, an opening 22 from the lower end of the hanging piece 7. A substantially L-shaped locking piece 9 extending to the side and a leg piece 10 extending vertically downward from the lower end of the standing piece 2 are provided. Also in such a shape member P2, the hanging piece 7 and the locking piece 9 are notched together with the horizontal piece 1 to form a first notch, and the horizontal piece 1 and the standing piece 2 are divided. By forming the cut-out portion and the second cut-out portion, it can be bent similarly to the profile shown in FIG. Then, the long shape member P2 is bent at four points to form a substantially square outer frame, and the upper piece 8 is fitted to the peripheral portion of the opening 22 so that the upper piece 8 is locked to the upper surface of the floor plate 21. The stop piece 9 is fixed to the auxiliary joist 27 with screws. In this way, one side of the profile P2 faces the outer peripheral side of the opening 22 and the other side faces the inner peripheral side of the opening 22. The main body 23 has a box shape opened upward, and has a substantially L-shaped claw portion 23a at the opening edge, and the claw portion 23a is engaged with the engagement piece 9 of the shape member P2 to open the opening portion 22. It is in. A substantially flat inner lid 30 is placed on the horizontal piece 1. Since the outer frame (shape member P2) is bent in a circular arc shape, the corners of the inner lid 30 can be formed in a circular arc shape accordingly, and it is safe to contact. In addition, when using the opening unit as an underfloor storage in this way, the shape attached to the peripheral edge of the opening can only be seen from the upper side, so the end piece protrudes from the lower side of the standing piece. There is no problem in appearance.

また、本発明の開口部ユニットは、天井ハッチとして用いるものであってもよい。この場合の開口部ユニットは、図５に示すように、天井４１に設けた略正方形の開口部２２に取り付けるものであって、外枠（形材Ｐ３）と、内蓋３０とを備えるものである。形材Ｐ３は、図１に示した形材と同様に、水平片１と、立設片と、垂下片と、上部片８とを有し、切取部、第一切欠部及び第二切欠部を形成したものである。そしてこの形材Ｐ３を四か所で屈曲させて略正方形の外枠を形成して、上部片８が天井４１の表面に係止するようにして開口部２２の周縁部に嵌め込んで固定してある。このようにすると、形材Ｐ３の一方側が開口部２２の外周側、他方側が開口部２２の内周側を向く。そして内蓋３０は、ヒンジ（図示省略）によって外枠（形材Ｐ３）に対して開閉自在に取り付けてあり、閉じた際には形材Ｐ３の水平片１に係止する。このように開口部ユニットを天井ハッチとして用いる場合、開放時には内蓋３０が外枠（形材Ｐ３）からぶら下がる状態となって、天井ハッチの下を通行する人が頭部をぶつける可能性があり、特に内蓋３０の角部が尖った形状だと危険であるが、本発明の開口部ユニットは、外枠（形材Ｐ３）を円弧状に屈曲させたことにより、それに合わせて内蓋３０の角部も円弧状に形成できるので、接触しても安全である。   The opening unit of the present invention may be used as a ceiling hatch. As shown in FIG. 5, the opening unit in this case is attached to the substantially square opening 22 provided on the ceiling 41, and includes an outer frame (shape member P <b> 3) and an inner lid 30. is there. The shape member P3 has the horizontal piece 1, the standing piece, the hanging piece, and the upper piece 8, similarly to the shape shown in FIG. 1, and has a cutout portion, a first notch portion, and a second notch portion. The part is formed. Then, the shape member P3 is bent at four places to form a substantially square outer frame, and the upper piece 8 is fitted and fixed to the peripheral portion of the opening 22 so that the upper piece 8 is locked to the surface of the ceiling 41. It is. In this way, one side of the profile P3 faces the outer peripheral side of the opening 22, and the other side faces the inner peripheral side of the opening 22. The inner lid 30 is attached to the outer frame (shape member P3) by a hinge (not shown) so as to be openable and closable. When the inner lid 30 is closed, the inner lid 30 is locked to the horizontal piece 1 of the shape member P3. When the opening unit is used as a ceiling hatch in this way, the inner lid 30 may hang from the outer frame (shape member P3) when opened, and a person passing under the ceiling hatch may hit the head. In particular, although it is dangerous if the corner of the inner lid 30 has a sharp shape, the opening unit of the present invention has an inner lid 30 according to the outer frame (shape member P3) bent in an arc shape. Since the corners of the can also be formed in an arc shape, it is safe to contact.

また、本発明の第二実施形態として、図６に示すように、立設片２の下側に入り込んで一方側に飛び出した端部片１ａ，１ｂを切除してもよい。この場合であっても、屈曲部分において水平片１の一方側端部は立設片２の下側に入り込んでいるので、上側から隙間が見えにくく外観が良好であり、さらに端部片１ａ，１ｂがなくなるので下側から見ても外観が良好となる。なお、端部片１ａ，１ｂは屈曲前にあらかじめ切除しておいてもよいし、屈曲後に飛び出した部分を切除してもよい。   Moreover, as 2nd embodiment of this invention, as shown in FIG. 6, you may cut off the edge part pieces 1a and 1b which entered the lower side of the standing piece 2, and jumped out to the one side. Even in this case, since one end of the horizontal piece 1 enters the lower side of the standing piece 2 at the bent portion, the gap is difficult to see from the upper side and the appearance is good, and the end piece 1a, Since 1b is eliminated, the appearance is good even when viewed from below. Note that the end pieces 1a and 1b may be excised in advance before bending, or portions protruding after the bending may be excised.

ところで、図４及び図５に示したような開口部ユニットを実際に施工する場合、略正方形の開口部の角部を円弧状に形成するのは非常に手間がかかるので、開口部の角部は直角に形成して、外枠の上部片によって開口部の角部を覆い隠す方法が現実的である。そのためには、上部片がある程度以上の幅を有していなければならないが、幅が広くなると、円弧状に屈曲させた外側部分の曲げ応力が増大して曲げ加工が困難になってしまう。そこで、幅広の上部片を有していても容易に曲げ加工を行うことができる第三実施形態を示す。   By the way, when actually constructing the opening unit as shown in FIGS. 4 and 5, it is very troublesome to form the corner of the substantially square opening in an arc shape. It is practical to form a right angle and cover the corner of the opening with the upper piece of the outer frame. For this purpose, the upper piece must have a certain width or more. However, if the width is increased, the bending stress of the outer portion bent in an arc shape increases, which makes bending difficult. Therefore, a third embodiment that can be easily bent even if it has a wide upper piece is shown.

第三実施形態は、図７（ａ），（ｂ）に示すように、水平片１と、水平片１の一方側端から垂直上方に延びる立設片２と、水平片１の他方側端から垂直下方に延びる垂下片７と、立設片２の上端から一方側に延びる上部片８と、垂下片７の下端から他方側に延びる略Ｌ字形状の係止片９と、同じく垂下片７の下端から一方側に延びる略Ｌ字形状の下部片３１とを有している。そして、第一実施形態と同様に、角部３を切り取って切取部４を形成し、水平片１を切り欠いて第一切欠部５及び第二切欠部６を形成してある。ただし、第一切欠部５は、垂下片７、係止片９及び下部片３１を水平片１と合わせて切り欠いてある。   As shown in FIGS. 7A and 7B, the third embodiment includes a horizontal piece 1, a standing piece 2 that extends vertically upward from one side end of the horizontal piece 1, and the other side end of the horizontal piece 1. A hanging piece 7 extending vertically downward from the top, an upper piece 8 extending from the upper end of the standing piece 2 to one side, a substantially L-shaped locking piece 9 extending from the lower end of the hanging piece 7 to the other side, and a hanging piece 7 and a substantially L-shaped lower piece 31 extending from the lower end to one side. And the corner | angular part 3 is cut off and the cutout part 4 is formed similarly to 1st embodiment, and the horizontal piece 1 is notched and the 1st notch part 5 and the 2nd notch part 6 are formed. However, the first notch 5 is notched with the hanging piece 7, the locking piece 9 and the lower piece 31 aligned with the horizontal piece 1.

そして第三実施形態においては、図７（ｃ）に示すように、上部片８が四つの構成部材８ａ，８ｂ，８ｃ，８ｄに分割してある。最も他方側の構成部材８ａ以外の各構成部材８ｂ，８ｃ，８ｄは、他方側に凸部８１を有しており、最も一方側の構成部材８ｄ以外の各構成部材８ａ，８ｂ，８ｃは、一方側に凹部８２を有していて、凸部８１を凹部８２に嵌合させて各構成部材８ａ，８ｂ，８ｃ，８ｄを連設してある。なお、凸部８１は基端よりも先端側が膨大となる形状であり、凹部８２も凸部８１と一致する形状である。よって、凸部８１を凹部８２に嵌合させる際には長手方向からスライドさせればよく、各構成部材８ａ，８ｂ，８ｃ，８ｄはスライド自在に嵌合する。また、最も他方側の構成部材８ａは、立設片２と一体に形成してある。   And in 3rd embodiment, as shown in FIG.7 (c), the upper piece 8 is divided | segmented into the four structural members 8a, 8b, 8c, 8d. Each component member 8b, 8c, 8d other than the most component member 8a has a convex portion 81 on the other side, and each component member 8a, 8b, 8c other than the most component member 8d is A concave portion 82 is provided on one side, and the constituent members 8a, 8b, 8c, and 8d are continuously provided by fitting the convex portion 81 into the concave portion 82. In addition, the convex part 81 is a shape in which the front end side is enormous from the base end, and the concave part 82 is also a shape that matches the convex part 81. Therefore, when the convex portion 81 is fitted into the concave portion 82, the convex portion 81 may be slid from the longitudinal direction, and the constituent members 8a, 8b, 8c, and 8d are slidably fitted. Further, the othermost constituent member 8 a is formed integrally with the standing piece 2.

このように構成した形材の第三実施形態を屈曲させる際には、図８に示すように、水平片１の一方側端の、切取部４によって立設片２と分断された部分（端部片１ａ，１ｂ）を、立設片２の下側に入り込ませることにより、第一実施形態と同様、水平片１及び立設片２部分について外観が良好になる。そして上部片８については、各構成部材８ａ，８ｂ，８ｃ，８ｄが異なる曲率で屈曲する。すなわち、他方側（円弧の内側）の構成部材は大きな曲率で、一方側（円弧の外側）の構成部材は小さな曲率で屈曲する。もし上部片８が一体であれば、一方側にいくほど曲げ応力が増大して曲げ加工が困難になるところ、本実施形態では上部片８を複数の構成部材８ａ，８ｂ，８ｃ，８ｄに分割してあり、隣接する構成部材同士が長手方向にスライド自在であるから、曲げ応力の増大が構成部材同士の滑りに置き換えられ、容易に曲げ加工を行うことができる。なお、各構成部材８ｂ，８ｃ，８ｄは、形材自体の長さよりも長くしておき、屈曲後に切りそろえればよい（図８中のＳ線で切断）。   When the third embodiment of the shape member configured as described above is bent, as shown in FIG. 8, a portion (end edge) separated from the standing piece 2 by the cutout portion 4 at one end of the horizontal piece 1. By allowing the pieces 1a and 1b) to enter the lower side of the standing piece 2, the appearance of the horizontal piece 1 and the standing piece 2 is improved as in the first embodiment. And about the upper piece 8, each structural member 8a, 8b, 8c, 8d bends with a different curvature. That is, the constituent member on the other side (inside the arc) bends with a large curvature, and the constituent member on the one side (outside the arc) bends with a small curvature. If the upper piece 8 is integrated, the bending stress increases as it goes to one side, and bending becomes difficult. In this embodiment, the upper piece 8 is divided into a plurality of constituent members 8a, 8b, 8c, and 8d. In addition, since adjacent constituent members are slidable in the longitudinal direction, an increase in bending stress is replaced by sliding between the constituent members, and bending can be easily performed. In addition, each component member 8b, 8c, 8d should just be longer than the length of the shape material itself, and should be cut off after bending (cut | disconnecting by the S line | wire in FIG. 8).

本発明は、上記の実施形態に限定されない。対象となる形材は、少なくとも水平片と立設片とを有していればよく、立設片は水平片に対して垂直なものに限られず、傾斜していてもよい。また、形材を屈曲させる具体的な手段はどのようなものであってもよく、上述したものとは別の構成の曲げ型を用いてもよいし、曲げ型を用いなくてもよい。さらに、構成部材の凸部及び凹部の断面形状は、くさび形、Ｔ字形や丸突起形など、短手方向に固定しかつ長手方向にスライド自在に嵌合できるものであれば、どのような形状であってもよい。また、本発明の形材は、一般に形材を用いる種々の製品に用いることができる。   The present invention is not limited to the above embodiment. The target shape is only required to have at least a horizontal piece and a standing piece, and the standing piece is not limited to a vertical piece with respect to the horizontal piece, and may be inclined. Further, any specific means for bending the profile may be used, and a bending die having a configuration different from that described above may be used, or the bending die may not be used. Furthermore, the cross-sectional shape of the convex part and the concave part of the constituent member can be any shape as long as it can be fixed in the short direction and slidable in the longitudinal direction, such as a wedge shape, a T-shape or a round projection shape. It may be. Moreover, the profile of this invention can be used for the various products which generally use a profile.
