【考案の詳細な説明】
（産業上の利用分野）
この考案は各種型鋼（パイプ・Ｈ型鋼・溝型
鋼・山型鋼・平鋼など）を螺旋状に曲げるもので
ある
（解決しようとする問題点）
現在 螺旋階段の手摺りなどを取り付ける際
ピツチの違いにより取り付けられず
現場で焼き曲げをしたり 短く切つて継ぎ剥ぎ
で取り付けるなど大変な苦労があり
苦労のわりに品物が汚いという現状であつた
本案はこの苦労を解消するものである
（従来の技術）
現在 曲げの機械にはアングルベンダー機や３
本ロール機などがある
アングルベンダー機は型のセツトによつて 多
彩な鋼材が曲げられた
しかし平面的なセツトの為 螺旋状に曲げる
場合は非常に不安定で無理があつた
それに螺旋状に曲がると径（曲がり）の修正時
機械本体が当たり機械による径の修正は不可能で
あつた
また３本ロール機の場合は平板の曲げには適し
いたが パイプや型鋼は曲げられなかつた
（実施例）
本案はその欠点を除き両方の良い点を兼ね備え
たものでローラーに型を三次元的にセツトした
これを図面によつて説明すれば３本のローラー
２，３に度数を刻んでおき型１を各度数に合わせ
てセツトしハンドル４でローラー２を上下させ
径を調整しモーターによりローラー３を回動させ
型鋼を曲げる物である
（考案の効果）
本案は上述の如き構造で三次元的型の固定によ
りローラーに対しての傾き（ピツチ）が一定にな
り より正確な螺旋曲が出来る[Detailed explanation of the invention] (Industrial application field) This invention is for bending various steel shapes (pipe, H-shaped steel, channel steel, angle steel, flat steel, etc.) into a spiral shape (problem to be solved) ) Currently when installing handrails etc. of spiral staircases
Due to the difference in pitch, they could not be installed, and it was very difficult to attach them by baking and bending them on site, cutting them short and patching them together.The current situation was that the product was dirty despite the effort. technology) Currently, bending machines include angle bender machines and 3
Angle bender machines, such as this roll machine, can bend a wide variety of steel materials using a set of molds.However, because of the flat set, it is extremely unstable and difficult to bend spirally. When correcting the diameter (bending), the machine body hit and it was impossible to correct the diameter using the machine.Also, in the case of a three-roll machine, it was suitable for bending flat plates, but it could not bend pipes or shaped steel (example) ) This proposal combines the good points of both except for the drawbacks, and the mold is set three-dimensionally on the roller.This can be explained using a drawing. Set according to each frequency and move roller 2 up and down with handle 4.
The diameter is adjusted and the roller 3 is rotated by a motor to bend the shaped steel. (Effect of the idea) This idea has the structure described above, and by fixing the three-dimensional die, the inclination (pitch) with respect to the roller is constant. Creates more accurate spiral curves
