合式ガードバ−に関する。[Detailed description of the invention] This invention relates to a fitting type guard bar for automobiles that can be used as a door guard bar used for reinforcement inside the door of an automobile. An extruded beam that is formed in a substantially U-shape or a plurality of consecutive U-shapes and has fitting parts at the top and bottom of the open side of the substantially U-shape, and a beam that is basically flat plate-shaped. The present invention relates to a fitting type guard bar for an automobile, which prevents the combination with a patch having a fitting part on one side thereof to be coupled to the fitting part of the beam.
例えば、第１図に示す自動車１０のドア１１゜１２を補

無用であることを意味する。This means that when comparing the automobile guard bar 4 shown in Fig. 4 with that shown in Fig. 3, except for the part 4c corresponding to the patch 2, the shaded parts 4b and 4b in Fig. 4 are useless in terms of strength. It means something.
又、第４図の如く閉鎖断面で中空の自動車用ガードバー
４を押出成形する場合、中子型が必要であり、その中子
型の強固な支持が十分にできないためにどうしても押出
成形品の薄肉化を制限される。In addition, when extruding a hollow automobile guard bar 4 with a closed cross section as shown in Fig. 4, a core mold is required, and since the core mold cannot provide sufficient strong support, the extrusion molded product inevitably has a thin wall. be restricted.
こうして第４図の自動車用ガードバー４は材料の不経済
