以下、本発明の実施の形態を図面に基づいて説明する。この実施例における形材は、既存の戸を取り外して残った既存枠の内周側に取り付けられる改修戸の化粧カバーとして用いるものであり、既存枠と躯体の納まりに応じて、一部の面を切断して長さを調整する必要がある。形材１の断面形状は、図１及び図２に示すように、略Ｌ字形であって、表面にラミネートフィルム２を貼ってあり、長さ調整が必要な面の裏面に、形材１の長手方向に沿って延びるガイド溝１１を形成してある。ガイド溝１１は、等間隔に並んで複数本形成してあり、板厚の１／３程度の深さの断面略半円形の溝となっていて、何れか１本のガイド溝１１を選択して、その選択したガイド溝１１ａに沿って形材を切断する。 Embodiments of the present invention will be described below with reference to the drawings. The profile in this example is used as a decorative cover for a refurbished door that is attached to the inner peripheral side of the existing frame that is left after removing the existing door, and depending on whether the existing frame and the frame are accommodated, part of the surface Need to cut and adjust the length. As shown in FIG. 1 and FIG. 2, the cross-sectional shape of the shape member 1 is substantially L-shaped, and the laminate film 2 is attached to the front surface thereof. A guide groove 11 extending along the longitudinal direction is formed. A plurality of guide grooves 11 are formed at equal intervals and have a semicircular cross section with a depth of about 1/3 of the plate thickness. Any one guide groove 11 is selected. Then, the profile is cut along the selected guide groove 11a.

図１に示すように、形材の切断には、ラミネートフィルム２を切断するための治具３と、カッター４と、ペンチ５を用いる。このうち、カッター４とペンチ５は一般的な工具であり、ここでは治具３について説明する。なお、以下において前後左右とは、図３に示す各方向のことである。治具３は、図２及び図３に示すように、上下に対向する略直方体形の上側胴部３３及び下側胴部３４と、上側胴部３３と下側胴部３４の後端部同士を接続する半円弧状の接続部３５を有し、全体で略Ｕ字形であって、全体が樹脂により成形されている。よって、上側胴部３３と下側胴部３４に上下から力を加えると、接続部３５がたわんで、上側胴部３３と下側胴部３４の前端部同士が接近するように変形させることができる。上側胴部３３は、前側の一部が左右に幅広に形成してあり、さらに上下に突出した前端面３６を形成してある。そして、前端面３６の下端部と上端部が前側に突出しており、下側の突出部の左右方向中央部及び上側の突出部の左右両端部を切り欠いて、カッター刃３７の受部３８ａ，３８ｂを形成してある。下側の受部３８ａは上下に貫通しており、上側の左右の受部３８ｂはそれぞれ下側に開口する形状である。カッター刃３７は、市販品を折り取り線で折り取った１片からなる平行四辺形のものであり、刃部３２側を下側の受部３８ａに嵌め、その反対側を上側の左右何れか（図３では左）の受部３８ｂに嵌めてある。この際、下側の受部３８ａが上下に貫通する形状なので、カッター刃３７の刃部３２の先端が、前端面３６から下側に突出する。また、上側の左の受部３８ｂを選択したことにより、刃部３２が右側を向いており、この場合、切断方向は左向きとなる。上側の右の受部３８ｂを選択すれば、刃部３２は左側を向き、切断方向は右向きとなる。そして、前端面３６の前側から矩形平板状の挟持板３９をネジ止めして取り付け、前端面３６と挟持板３９とでカッター刃３７を挟み込んで固定してある。また、下側胴部３４の前端部の上側面には、２本のガイド部３１ａ，３１ｂを形成してある。ガイド部３１ａ，３１ｂは、下側胴部３４の左右方向に沿って延びる断面略三角形の突条からなり、２本のガイド部３１ａ，３１ｂの間隔は、形材１のガイド溝１１の間隔と等しく、前側のガイド部３１ａが、上側胴部３３の刃部３２に対向している。よって、上側胴部３３と下側胴部３４に上下から力を加えると、刃部３２と前側のガイド部３１ａが接近する。 As shown in FIG. 1, a jig 3 for cutting the laminate film 2, a cutter 4, and pliers 5 are used for cutting the profile. Of these, the cutter 4 and the pliers 5 are general tools, and the jig 3 will be described here. In the following, front, rear, left and right refer to each direction shown in FIG. As shown in FIGS. 2 and 3, the jig 3 includes a substantially rectangular parallelepiped upper body portion 33 and a lower body portion 34 that are vertically opposed to each other, and rear end portions of the upper body portion 33 and the lower body portion 34. Has a semi-arcuate connecting portion 35 for connecting with each other, is substantially U-shaped as a whole, and is entirely molded of resin. Therefore, when a force is applied to the upper body portion 33 and the lower body portion 34 from above and below, the connecting portion 35 bends and the front ends of the upper body portion 33 and the lower body portion 34 can be deformed so as to approach each other. it can. A part of the front side of the upper body portion 33 is formed wide on the left and right sides, and further, a front end surface 36 protruding vertically is formed. Then, the lower end portion and the upper end portion of the front end face 36 project toward the front side, the left and right center portions of the lower projecting portion and the left and right end portions of the upper projecting portion are cut out, and the receiving portion 38a of the cutter blade 37, 38b is formed. The lower receiving portion 38a penetrates vertically, and the upper left and right receiving portions 38b each have a shape that opens downward. The cutter blade 37 is a parallelogram formed of one piece obtained by breaking off a commercially available product with a folding line, the blade portion 32 side is fitted to the lower receiving portion 38a, and the opposite side is either the upper left or right side. It is fitted in the receiving portion 38b (left in FIG. 3). At this time, since the lower receiving portion 38a penetrates vertically, the tip of the blade portion 32 of the cutter blade 37 projects downward from the front end face 36. Further, by selecting the upper left receiving portion 38b, the blade portion 32 faces the right side, and in this case, the cutting direction is leftward. When the upper right receiving portion 38b is selected, the blade portion 32 faces the left side and the cutting direction is the right direction. Then, a rectangular flat plate-shaped holding plate 39 is attached by screwing from the front side of the front end face 36, and the cutter blade 37 is sandwiched and fixed between the front end face 36 and the holding plate 39. Further, two guide portions 31a and 31b are formed on the upper side surface of the front end portion of the lower body portion 34. The guide portions 31a and 31b are formed of protrusions having a substantially triangular cross section that extends along the left-right direction of the lower body portion 34, and the distance between the two guide portions 31a and 31b is equal to the distance between the guide grooves 11 of the frame member 1. Similarly, the front guide portion 31a faces the blade portion 32 of the upper body portion 33. Therefore, when a force is applied to the upper body portion 33 and the lower body portion 34 from above and below, the blade portion 32 and the front guide portion 31a approach each other.

次に、図１及び図２に基づき、本発明の、表面にラミネートフィルム２を貼ってあり裏面に複数のガイド溝１１を有する形材１の切断方法の各工程について詳述する。まず、この形材１の取付対象の形状や構造に応じて、どのガイド溝１１の位置で切断するかを選択する。次に、選択したガイド溝１１ａに、治具３の前側のガイド部３１ａを沿わせて、治具３の刃部３２で表面のラミネートフィルム２を切断する（図１（ａ））。この際、図２に示すように、前側のガイド部３１ａを選択したガイド溝１１ａに挿入すると、後側のガイド部３１ｂは、選択したガイド溝１１ａの隣のガイド溝１１ｂに挿入される。形材１の裏面のガイド溝１１ａ，１１ｂに治具３のガイド部３１ａ，３１ｂを挿入した状態で、治具３の上側胴部３３と下側胴部３４を上下から挟むようにして力を加えると、接続部３５がたわんで、前側のガイド部３１ａに刃部３２が接近し、形材１の表面のラミネートフィルム２の、選択したガイド溝１１ａに対応する位置に当接する。そして、刃部３２をラミネートフィルム２に当接させた状態で、治具３を左右方向に摺動させることで、刃部３２により、選択したガイド溝１１ａの位置で、ラミネートフィルム２が切断される。次に、選択したガイド溝１１ａをカッター４で切り込む（図１（ｂ））。この際、形材１の裏面から選択したガイド溝１１ａにカッター４の刃の先端を挿入し、そのままカッター４を摺動させればよく、それ以外の工具は不要である。カッター４によって形材１を切断する必要はなく、ある程度の深さの切り込みを形成すれば十分である。次に、ペンチ５により、選択したガイド溝１１ａで形材１を折り取る（図１（ｃ））。この際、ペンチ５で形材１の選択したガイド溝１１ａより先端側の部分を掴み、力を加えて折り曲げるが、長い形材１を１度に折り曲げることはできないので、長手方向に沿って、部分的に順次折り曲げていき、形材１を金属疲労により分離させる。以上で、形材１の切断が完了する。 Next, based on FIG. 1 and FIG. 2, each step of the method for cutting the profile 1 having the laminate film 2 on the front surface and the plurality of guide grooves 11 on the back surface of the present invention will be described in detail. First, depending on the shape or structure of the object to which the frame 1 is attached, the position of the guide groove 11 to be cut is selected. Next, the guide portion 31a on the front side of the jig 3 is placed along the selected guide groove 11a, and the laminate film 2 on the surface is cut by the blade portion 32 of the jig 3 (FIG. 1A). At this time, as shown in FIG. 2, when the front guide portion 31a is inserted into the selected guide groove 11a, the rear guide portion 31b is inserted into the guide groove 11b adjacent to the selected guide groove 11a. With the guide portions 31a and 31b of the jig 3 inserted in the guide grooves 11a and 11b on the back surface of the shape member 1, when force is applied by sandwiching the upper body portion 33 and the lower body portion 34 of the jig 3 from above and below. The connecting portion 35 bends, the blade portion 32 approaches the front guide portion 31a, and abuts on the position of the laminate film 2 on the surface of the profile 1 corresponding to the selected guide groove 11a. Then, by sliding the jig 3 in the left-right direction with the blade portion 32 in contact with the laminate film 2, the blade portion 32 cuts the laminate film 2 at the position of the selected guide groove 11a. It Next, the selected guide groove 11a is cut by the cutter 4 (FIG. 1(b)). At this time, the tip of the blade of the cutter 4 may be inserted into the guide groove 11a selected from the back surface of the shape member 1 and the cutter 4 may be slid as it is, and no other tool is required. It is not necessary to cut the profile 1 with the cutter 4, and it is sufficient to form a cut having a certain depth. Next, the pliers 5 breaks the profile 1 along the selected guide groove 11a (FIG. 1C). At this time, the tip end side of the selected guide groove 11a of the shape member 1 is grasped with the pliers 5 and bent by applying force, but since the long shape member 1 cannot be bent at one time, The parts 1 are sequentially bent and the profile 1 is separated by metal fatigue. With the above, the cutting of the profile 1 is completed.

このような形材１の切断方法によれば、治具３によりラミネートフィルム２を先に切断するので、ラミネートフィルム２にめくれや伸びが生じることがなく、製品の品質が向上する。また、治具３に２本のガイド部３１ａ，３１ｂを設けてあるので、ラミネートフィルム２を切断する際に、治具３を安定して摺動させることができる。さらに、治具３の上側の左右の受部３８ｂの何れにカッター刃３７を嵌めるかによって、刃部３２の向きが変わり、作業者の利き腕などに応じて、治具３の切断方向を選択できる。 According to such a method of cutting the shape member 1, since the laminate film 2 is first cut by the jig 3, the laminate film 2 is not turned or stretched, and the quality of the product is improved. Further, since the jig 3 is provided with the two guide portions 31a and 31b, the jig 3 can be stably slid when the laminate film 2 is cut. Furthermore, the direction of the blade portion 32 changes depending on which of the left and right receiving portions 38b on the upper side of the jig 3 the cutter blade 37 is fitted in, and the cutting direction of the jig 3 can be selected according to the dominant arm of the operator. ..

また、ラミネートフィルム２を先に切断することで、形材をねじり取ることも可能となる。すなわち、上記の切断方法において、ペンチ５で形材を折り取る代わりに、図４に示すように、ペンチ５で形材１の選択したガイド溝１１ａより先端側の部分を掴み、ペンチ５を回転させて、ペンチ５に形材１の不要部分を巻き付けるようにして、形材１を選択したガイド溝１１ａで分離させていく。この方法は、ラミネートフィルム２が先に切断されていないと不可能であり、折り取る方法と比較して、より作業効率が向上する。 Further, by cutting the laminate film 2 first, it is possible to twist off the profile. That is, in the above cutting method, instead of breaking the profile with the pliers 5, as shown in FIG. 4, the pliers 5 grip the part of the profile 1 on the tip side of the selected guide groove 11a and rotate the pliers 5. Then, the unnecessary portion of the profile 1 is wound around the pliers 5, and the profile 1 is separated at the selected guide groove 11a. This method is impossible unless the laminate film 2 is cut first, and the working efficiency is further improved as compared with the method of breaking it off.

本発明は、上記の実施形態に限定されない。たとえば、治具は、ガイド溝に沿ってラミネートフィルムを切断できるものであれば、どのような構造のものであってもよく、金属製のものや、ヒンジ構造により刃部とガイド部が接近・離隔するものであってもよい。また、本発明の形材の切断方法は、種々の建材その他の構造物を構成する形材に適用できる。 The present invention is not limited to the above embodiment. For example, the jig may have any structure as long as it can cut the laminate film along the guide groove, and the jig is made of metal or the hinge structure allows the blade portion and the guide portion to approach each other. It may be separated. Further, the method for cutting a profile according to the present invention can be applied to various building materials and other profiles that constitute structures.
