Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、内外両面のドアパネルを断面コ字状の補強材
を介して接合して成る金属製ドアに関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a metal door formed by joining door panels on both inner and outer sides via a reinforcing member having a U-shaped cross section.
内外両面のドアパネルを断面コ字状の補強材を介して接
合した金属製ドアにおいては、ドアパネルが開き変形す
ることがある。In a metal door in which door panels on both inner and outer surfaces are joined via a reinforcing member having a U-shaped cross section, the door panels may open and deform.
この開き変形を防止するために、補強材にスリットを形
成し、ドアパネルの折返し板に突起を一体形成し、その
突起をスリットに差し込むようにした金属製ドアが実開
昭61-8283号公報に開示されている。In order to prevent this opening deformation, a slit is formed in the reinforcing material, a protrusion is integrally formed on the folding plate of the door panel, and the metal door in which the protrusion is inserted into the slit is disclosed in Japanese Utility Model Laid-Open No. 61-8283. It is disclosed.
かかる金属製ドアであると、補強材にスリットを形成す
るために補強材の強度が低下しドアの強度が弱くなる。In the case of such a metal door, the strength of the reinforcing material is lowered because the slit is formed in the reinforcing material and the strength of the door is weakened.
特に大型のドアであるとドアパネルが大きくなるので、
スリットを長くして支持強度を大とする必要があり、補
強材の強度がより弱くなってしまう。Especially for large doors, the door panel becomes large,
It is necessary to lengthen the slit to increase the supporting strength, and the strength of the reinforcing material becomes weaker.
また、ドアパネルの折返し板に突起を一体形成してある
ので、折返し板を突起だけ長くし、突起以外の部分を切
断して突起を一体形成しているから、切断長さが長くな
って切断加工が困難となるばかりか、材料の歩留りが悪
くなる。Also, since the projection is integrally formed on the folding plate of the door panel, the folding plate is lengthened only by the projection, and the portion other than the projection is cut to integrally form the projection, so the cutting length becomes longer and the cutting process is performed. Not only becomes difficult, but also the yield of the material deteriorates.
そこで、本考案は前述の課題を解決できるようにした金
属製ドアを提供することを目的とする。Then, this invention aims at providing the metal door which was able to solve the above-mentioned subject.
補強材に係合溝を有する係合材を設け、ドアパネルの折
返し板に切欠部を形成し、その切欠部と係合溝を係合し
てドアパネルの開き変形を防止するようにした金属製ド
アであり、これによって、補強材の強度が低下すること
がないと共に、折返し板の切断加工が容易となる。A metal door in which an engaging member having an engaging groove is provided in the reinforcing member, a cutout portion is formed in the folded-back plate of the door panel, and the notch portion and the engaging groove are engaged to prevent opening deformation of the door panel. As a result, the strength of the reinforcing material does not decrease, and the folding plate is easily cut.
第３図に示すように、内外両面のドアパネル1,1はコ字
状の補強材２で接合され、そのドアパネル1,1間に芯材
３が設けられて金属製ドアを構成し、ドアパネル１の端
部はＬ字状に折曲されて端面板４、折返し板５を形成し
ている。As shown in FIG. 3, door panels 1 and 1 on both inner and outer surfaces are joined by a U-shaped reinforcing material 2, and a core material 3 is provided between the door panels 1 and 1 to form a metal door. The end portion of is bent into an L shape to form an end face plate 4 and a folded plate 5.
前記補強材２は第２図のように、背面板６と取付板7,7
でコ字状となり、その背面板６に係合材８がビス９で取
付けてある。なお、スポット溶接で取付けても良い。As shown in FIG. 2, the reinforcing member 2 includes a rear plate 6 and mounting plates 7,7.
It has a U-shape, and an engaging member 8 is attached to its rear plate 6 with screws 9. It may be attached by spot welding.
該係合材８は板状となり、両側に係合溝10,10が形成さ
れている。The engagement member 8 has a plate shape and has engagement grooves 10 and 10 formed on both sides.
前記ドアパネル１の折返し板５には第１図に示すように
切欠部11が形成され、この切欠部11の両側部分5a,5aが
前記係合材８の一対の係合溝10,10に係合するようにし
てあり、これによってドアパネル１が開き変形しないよ
うにしてある。As shown in FIG. 1, the folding plate 5 of the door panel 1 is formed with a notch portion 11, and both side portions 5a, 5a of the notch portion 11 are engaged with the pair of engaging grooves 10, 10 of the engaging member 8. The door panel 1 is prevented from opening and deforming.
補強材２に設けた係合材８の一対の係合溝10,10と、ド
アパネル１の折返し板５における切欠部11の両側部分5
a,5aが係合するから、ドアパネル１が開き変形すること
を防止できる。A pair of engaging grooves 10, 10 of the engaging member 8 provided in the reinforcing member 2 and both side portions 5 of the cutout 11 in the folding plate 5 of the door panel 1.
Since the a and 5a are engaged, it is possible to prevent the door panel 1 from being opened and deformed.
補強材２に係合材８を設けたので、補強材２の強度が弱
くなることがなく、金属製ドアの強度を強くできる。Since the reinforcing member 2 is provided with the engaging member 8, the strength of the reinforcing member 2 does not decrease, and the strength of the metal door can be increased.
ドアパネル１の折返し板５に切欠部11を形成したので、
折返し板５を部分的に切断すれば良く、切断長さが短か
くなって切断加工が容易となるばかりか、材料の歩留り
も向上する。Since the notch 11 is formed in the folding plate 5 of the door panel 1,
It suffices if the folding plate 5 is partially cut, the cutting length becomes short, the cutting process becomes easy, and the material yield is improved.
