Description

【０００１】
【発明の属する技術分野】
本発明は、結合押出形材、結合用押出形材および結合押出形材の製造方法に関する。
【０００２】
【従来の技術】
従来の結合押出形材製パネルは、図３に示すように、上下に隣り合う２つのアルミニウム中空押出形材製パネル(41)(42)とこれらパネル(41)(42)の結合に用いられる結合ピン(43)とを備え、上位パネル(41)の下縁部中央に嵌合凹部(44)が設けられ、下位パネル(42)の上縁部中央には嵌合凸部(45)が設けられ、嵌合凹部(44)と嵌合凸部(45)とが嵌め合わされた状態における嵌合凹部(44)の両側内面とこれらに対向する嵌合凸部(45)の両側外面にそれぞれピン孔形成用溝(46a)(46b)が相互に向かい合って設けられており、上位パネル(41)の嵌合凹部(44)に下位パネル(42)の嵌合凸部(45)が嵌め入れられてピン孔(47)が設けられ、ピン孔(47)に結合ピン(43)が圧入されて上位パネル(41)と下位パネル(42)とが結合され、下位パネル(42)の上縁部両側には突出壁(48)が設けられ、突出壁(48)と嵌合凸部(45)間が凹溝(49)となされ、凹溝(49)に上位パネル(41)の嵌合凹部(44)両側に設けられた凸条(51)が嵌め込まれ、更に凸条(51)の基部両側には略逆Ｖ形溝(52)が形成され、略逆Ｖ形溝(52)に下位パネル(42)の突出壁(48)先端が嵌め入れられているものであった。
【０００３】
【発明が解決しようとする課題】
しかしながら、上述のものでは、上位パネル(41)と下位パネル(42)の一方または両方に押出し方向の曲りがある場合、下位パネル(42)の突出壁(48)先端と上位パネル(41)の略逆Ｖ形溝(52)との間に目立った隙間(S) が生じ易い。この隙間(S) は結合されたパネル同士の外観を損ねると共に隙間(S) に異物が入るので好ましくない。
【０００４】
そのため、パネル(41)(42)同士の結合強度の面ではピン孔(47)の両端部だけに短い結合ピン(43)を圧入すれば良い場合でも、上記隙間(S) をなくすために、ピン孔(47)の長さと同じ長さの長尺の結合ピン(43)をピン孔(47)の全長にわたって圧入することを余儀無くされ、かかる長尺の結合ピン(43)の圧入は非常に困難な作業となることから、パネル(41)(42)同士の結合に多大な手間と時間を要するという問題があった。
【０００５】
本発明の目的は、押出形材に押出し方向の曲りがある場合でも、ピン孔の全長にわたって長尺の結合ピンを圧入することなく、押出形材の曲りを容易に矯正して押出形材間に目立った隙間が生じないようにした結合押出形材、結合用押出形材および結合押出形材の製造方法を提供することにある。

本発明によれば、上位の押出形材の下縁部に、上下壁および上下壁の左縁部同士をつなぐ左壁よりなる横断面略逆コ字形の嵌合凹部と嵌合凹部の下壁の右縁部から左斜め下方へ湾曲状に伸びる嵌合雄部が設けられ、下位の押出形材の上縁部に、上位の押出形材の略逆コ字形嵌合凹部に嵌め入れられる左向き嵌合凸部が設けられ、嵌合凸部の下側における左側面には先端部が横断面略Ｃ形となされた張出し部が設けられ、略Ｃ形の先端部内側が嵌合雄部の先端部が嵌め入れられる嵌合雌部となされ、張出し部の基部上面から嵌合凸部の下側における左側面が嵌合雄部の右側面に対応する凹弧面となされており、上位の押出形材の嵌合雄部を下位の押出形材の凹弧面に当接させて、上位の押出形材の嵌合雄部を下位の押出形材の凹弧面に沿って回動させつつ、嵌合雄部の先端部を嵌合雌部に嵌め入れると共に、上位の押出形材の嵌合凹部と下位の押出形材の嵌合凸部を嵌め合せているから、上位の押出形材の嵌合雄部を下位の押出形材の凹弧面に当接させて、上位の押出形材の嵌合雄部を下位の押出形材の凹弧面に沿って回動させつつ、嵌合雄部の先端部を嵌合雌部の凹所に嵌め入れる際に、これら押出形材に押出方向の曲りがある場合でも、これがある程度矯正されるため、上位の押出形材の嵌合凹部と下位の押出形材の嵌合凸部とを嵌め合せた際に、嵌合凸部の上面と嵌合凹部の上壁下面間に目立った隙間が生じない。
【００１７】
そして、上位の押出形材の横断面略逆コ字形嵌合凹部の下壁の上面にはピン孔形成用溝が設けられ、下位の押出形材の左向き嵌合凸部の下面には上位の押出形材のピン孔形成用溝と相互に向かい合うピン孔形成用溝が設けられているから、両押出形材の向かい合うピン孔形成用溝に圧入された結合ピンによって、一旦矯正された押出形材が弾性で元の状態に戻ったりせず、両押出形材の結合状態が維持される。
【００１８】
従って、従来のように、結合される押出形材の曲りを矯正するために、常にピン孔の全長にわたって長尺の結合ピンを圧入する必要はなく、押出形材同士の結合強度の面でこれら押出形材の両端部だけに短い結合ピンを圧入すれば良い場合にはこれで済ませることができ、しかも両押出形材に上述したように目立った隙間が生じない。

A fitting male part extending in a curved shape from the right edge of the lower wall to the left obliquely downward is provided, and a pin hole forming groove is provided on the upper surface of the lower wall, and the upper edge of the lower extruded shape member In addition, a left-facing fitting convex portion that is fitted into a substantially inverted U-shaped fitting concave portion of the upper extruded shape member is provided, and a tip portion of the left side surface on the lower side of the fitting convex portion has a substantially C-shaped cross section. A projecting female portion into which the distal end portion of the fitting male portion is fitted, and the left side surface on the lower side of the fitting convex portion from the upper surface of the base portion of the overhanging portion). Is a concave arc surface corresponding to the right side surface of the fitting male part, and the lower surface of the left-facing fitting convex part is mutually connected to the groove for forming the pin hole of the upper extruded profile. Opposite pin hole forming grooves are formed, and the fitting male part of the upper extruded profile is brought into contact with the concave arc surface of the lower extruded profile, and the fitting male part of the upper extruded profile is lowered. The tip of the fitting male part is fitted into the fitting female part while being rotated along the concave arc surface of the extruded shape part, and the fitting concave part of the upper extrusion shape and the lower extrusion shape are fitted. fitted to convex portions, both the coupling pin into the pin hole forming groove facing the extruded material that is bonded is pressed both extruded profile join the extruded profile.

The bonded extruded profile according to claim 1, wherein the two upper and lower extruded profiles are made of aluminum.

The upper and lower extruded profiles are assembled into a set, and the upper extruded profile is formed with a fitting recess having a substantially inverted U-shaped cross section comprising a lower wall and a left wall connecting the upper and lower walls and the left edges of the upper and lower walls. a fitting male portion extending in a curved shape to the left obliquely downward from the right edge of the lower wall of the fitting recess is provided, and pin holes forming grooves are provided on the upper surface of the lower wall, the lower press Degata The upper edge of the material is provided with a left-facing fitting convex portion that is fitted into the upper extruded shape approximately inverted U-shaped fitting concave portion, and the tip portion crosses the left side surface below the fitting convex portion. An overhanging portion having a substantially C-shaped surface is provided, and the inside of the substantially C-shaped tip end portion is a fitting female portion into which the tip end portion of the fitting male portion is fitted. The left side surface on the lower side is a concave arc surface corresponding to the right side surface of the fitting male part. Coupling extruded profiles which use the groove and mutually opposite pin holes forming grooves are formed.

On the lower edge, the upper and lower walls and the left wall that connects the left and right edges of the upper and lower walls are curved in a diagonally downward leftward direction from the right edge of the lower wall of the fitting recess A high-order extruded shape member with an extending fitting male part and a pin hole forming groove on the upper surface of the lower wall, and a substantially inverted U-shaped fitting concave part of the high-order extruded shape member at the upper edge A left-facing fitting convex portion to be fitted into the fitting convex portion is provided, and a protruding portion whose distal end portion has a substantially C-shaped cross section is provided on the left side of the lower side of the fitting convex portion. The distal end of the fitting male part is fitted into the fitting female part, and the left side surface on the lower side of the fitting convex part from the upper surface of the base part of the overhanging part is a concave arc surface corresponding to the right side surface of the fitting male part. The lower side of the left-facing fitting convex part is formed with a pin hole forming groove opposite to the pin hole forming groove of the upper extruded profile. Provides two extruded profile with extrusions, the fitting male portion of the extruded profile of the upper is brought into contact with the concave arc face of the lower extrusions, Hamagoyu portion of the extruded profile of the upper Is fitted along the concave arc surface of the lower extruded profile, and the tip of the fitting male part is fitted into the fitted female part, and the fitting recessed part of the upper extruded profile and the lower extruded profile are inserted. the method for producing combined fitting the fitting convex portion, by press-fitting the coupling pin into the pin hole forming grooves facing the two extruded profiles you combine both extrusions join the extruded profile.
