鉄で意匠部を構成して塗装やテープの貼着で意匠性を付与する従来例１のドアフレーム２ｂと、ステンレスのフレームモール３ａを鉄のドアフレーム本体２ａに取り付ける従来例２のドアフレームとでは、前述のように、ドアフレーム（本体）の形状が異なる。
このため、鉄で意匠部を構成して塗装等で意匠性を付与するドアフレームと、ステンレスのフレームモールを鉄のドアフレーム本体に取り付けて成るドアフレームとを製造する場合には、自動車の型式が同じであるにもかかわらず、それぞれ形状の異なるドアフレーム（本体）をロールフォーミングで製造する必要があり、非常にコスト高であった。
即ち、上記の各ドアフレームに関して、ドアフレーム（本体）を鉄製の長尺状板材からロールフォーミングするための設備として、金型、ロールの駒、長尺状板材を所望の方向に曲げるための曲げ型、長尺状板材を所望の長さで切断するためのプレス型等をそれぞれ用意して、それぞれ稼働させる必要があり、極めてコスト高であった。
このため、鉄で意匠部を構成するドアフレームと、ステンレスのフレームモールを鉄のドアフレーム本体に取り付けるドアフレームとに関して、ドアフレーム（本体）の形状を共通化して、設備等のコストを低減したいという要請がある。
本発明は、鉄で意匠部を構成して塗装等で意匠性を付与するドアフレームや、ステンレスのフレームモールをドアフレーム本体に取り付けて成るドアフレームに関して、共通のドアフレーム本体を使用できるようにして、設備のコストや、工数・部品コストを低減することを第１の目的とする。 The door frame 2b of Conventional Example 1 in which the design portion is made of iron and the design property is imparted by painting or tape attachment, and the door frame of Conventional Example 2 in which the stainless steel frame molding 3a is attached to the iron door frame body 2a. Then, as described above, the shape of the door frame (main body) is different.
For this reason, when manufacturing a door frame that has a design part made of iron and imparts design properties by painting or the like, and a door frame formed by attaching a stainless steel frame molding to an iron door frame body, the model of the automobile However, it is necessary to manufacture door frames (main bodies) having different shapes by roll forming, which is very expensive.
That is, for each of the door frames described above, as a facility for roll forming the door frame (main body) from a long iron plate material, bending for bending a mold, a roll piece, and the long plate material in a desired direction. It was necessary to prepare a die and a press die for cutting a long plate material to a desired length and operate them, respectively, which was extremely expensive.
For this reason, we want to reduce the cost of equipment, etc. by sharing the shape of the door frame (main body) with respect to the door frame whose design part is made of iron and the door frame for attaching the stainless steel frame molding to the iron door frame main body. There is a request.
The present invention makes it possible to use a common door frame main body with respect to a door frame in which a design portion is made of iron and design is imparted by painting or the like and a door frame formed by attaching a stainless steel frame molding to the door frame main body. Therefore, the first object is to reduce the cost of equipment, the number of man-hours and the cost of parts.

鉄の長板のロールフォーミングによりドアフレーム本体２ｂと意匠部２０３０ｂを一体に形成する従来例１のドアフレームでは、剛性に寄与しない意匠部２０３０ｂの肉厚を他の部位の肉厚より薄く形成して軽量化することは、極めて困難である。
本発明は、意匠部を備えた自動車用ドアフレームに関して、鉄製の素材で意匠部を構成することによりコストを低減しようとする際に、剛性に寄与しない意匠部を薄肉に形成して軽量化することを第２の目的とする。 In the door frame of Conventional Example 1 in which the door frame main body 2b and the design portion 2030b are integrally formed by roll forming of a long iron plate, the thickness of the design portion 2030b that does not contribute to rigidity is formed thinner than the thickness of other portions. It is extremely difficult to reduce the weight.
The present invention relates to an automotive door frame having a design portion, and when the cost is reduced by configuring the design portion with an iron material, the design portion that does not contribute to rigidity is thinned to reduce the weight. This is the second purpose.

本発明は、下記［１］〜［２］のように構成される。

構成１のモール付ドアフレームは、ドアフレーム本体にフレームモールを取り付けて成り、ガラスラン装着用のチャンネル部とウエザストリップ装着用のリテーナ部とドア閉時に車体のドア開口縁部に当接される膨出部を有し、前記ドアフレーム本体は、前記チャンネル部及び前記リテーナ部の少なくとも一部と前記膨出部を構成し、且つ、反膨出部側に上下二つの縁部が重ねられた被取付部を有するように、鉄製の長尺状板材をロールフォーミング成形して成り、前記フレームモールは、車外側が意匠面とされるモール意匠部と該モール意匠部の上縁から意匠面の裏面側へ折り返した後に車内側へ立設された脚部を有するように、前記ドアフレーム本体成形用の板材より薄肉の鉄製の長尺状板材を折り曲げ形成して成り、前記ドアフレーム本体の被取付部に前記フレームモールの脚部を重ね合わせてスポット溶接することにより、前記フレームモールを前記ドアフレーム本体に取り付けて成る。
このため、フレームモールとしてステンレス製で上記と同形状のフレームモールを用意することにより、鉄素材で意匠部を構成して塗装やテープの貼着で意匠性を付与する構成１のドアフレームと、上記用意したステンレス製のフレームモールを構成１のフレームモールに代えて用いるドアフレームとで、ドアフレーム本体を共通化でき、ドアフレーム本体製造用の設備コスト（金型、ロールの駒、長尺状板材を所望の方向に曲げるための曲げ型、長尺状板材を所望の長さで切断するためのプレス型等等の設備コスト）を低減できる。また、工数や部品コストも低減できる。
また、剛性に寄与しない意匠部の肉厚を、他の部位の肉厚より薄く形成できるため、軽量化することができる。
また、取り付け時にボルト・ナット締めやリベット止めの工数が不要であるため、生産性を改善でき、コストも低減できる。
また、ドアフレーム本体とフレームモールが同じ鉄であり、異種金属接触による電蝕が生じないため、絶縁層も不要であり、工数・部品点数の増加を回避できる。 The door frame with a molding having the structure 1 is formed by attaching the frame molding to the door frame main body, and comes into contact with the channel portion for mounting the glass run, the retainer portion for mounting the weather strip, and the door opening edge of the vehicle body when the door is closed. The door frame body constitutes the bulging portion and at least a part of the channel portion and the retainer portion, and two upper and lower edges are overlapped on the anti-bulging portion side. The frame molding is formed from the upper edge of the molding design portion and the molding design portion, the outer surface of the molding being a design surface. The door frame is formed by bending a long iron plate that is thinner than the plate for forming the door frame main body so as to have leg portions that are erected on the inner side of the vehicle after being folded back to the rear side of the door frame.

In addition, man-hours and parts costs can be reduced.
Moreover, since the thickness of the design part which does not contribute to rigidity can be formed thinner than the thickness of another part, it can reduce in weight.
In addition, since no man-hours for tightening bolts and nuts and riveting are required during installation, productivity can be improved and costs can be reduced.
Further, since the door frame body and the frame molding are made of the same iron, and no electric corrosion occurs due to contact with different metals, an insulating layer is unnecessary, and an increase in the number of man-hours and parts can be avoided.

構成２のモール付ドアフレームは、構成１に於いて、前記フレームモールは、前記モール意匠部の両縁からそれぞれ意匠面の裏面側へ折り返した後に車内側へ立設された二つの脚部を有するように、前記ドアフレーム本体成形用の板材より薄肉の鉄製の長尺状板材を折り曲げ形成して成り、前記フレームモールのチャンネル部側の脚部にはスポット溶接用の少なくとも一つの孔が形成されており、前記フレームモールの少なくとも一方の脚部の先端は他方の脚部との間隙が拡がる方向へ曲げられており、前記ドアフレーム本体の被取付部の根元付近であって前記当接用屈曲部に対応する部位には該当接用屈曲部に対応する段部が形成され、前記ドアフレーム本体の被取付部に前記フレームモールの両脚部を外嵌して、前記当接用屈曲部を対応する段部にて停止させた後、前記リテーナ部側の脚部を前記孔の位置にて前記被取付部にスポット溶接することにより、前記フレームモールを前記ドアフレーム本体に取り付けて成る。
このため、構成１と同じ効果を奏する他、下記の効果を更に奏する。
即ち、フレームモールの下側脚部の当接用屈曲部が、ドアフレーム本体の被取付部の対応する段部の位置により規定される停止位置にて確実に停止されるため、幅方向の取り付けバラツキが無くなる。
また、フレームモールの少なくとも一方の脚部の先端は、他方の脚部との間隙が拡がる方向へ形成されているため、ドアフレーム本体の被取付部にフレームモールの両脚部を外嵌する作業が容易である。 The door frame with a molding of Configuration 2 is that in Configuration 1, the frame molding has two leg portions that are erected on the vehicle inner side after being folded back from both edges of the molding design portion to the back side of the design surface.

図示のように、本ドアフレームは、鉄製のドアフレーム本体２の下縁部２７１と上縁部２７２の積層部である被取付部２７を、鉄製のフレームモール３の下脚部３１と上脚部３２とで挟むようにして、被取付部２７にフレームモール３の両脚部を外嵌し、フレームモール３の下脚部３１の先端の下脚屈曲端部（当接用屈曲部）３３をドアフレーム本体２の下縁部２７１の根元部分である段部２３に当接させて一定位置で停止させた後、スポット溶接して成る。   As shown in the figure, the door frame includes an attachment portion 27 that is a laminated portion of a lower edge portion 271 and an upper edge portion 272 of the iron door frame main body 2, and a lower leg portion 31 and an upper leg portion of the iron frame molding 3. 32, the both legs of the frame molding 3 are externally fitted to the attached portion 27, and the lower leg bent end (bending portion for contact) 33 at the tip of the lower leg 31 of the frame molding 3 is attached to the door frame body 2. After being brought into contact with the step portion 23 which is the base portion of the lower edge portion 271 and stopping at a fixed position, spot welding is performed.

フレームモール３は、ドアフレーム本体２と同じ素材で且つドアフレーム本体２より薄肉の鉄製の長尺状の板材を折り曲げ形成したものであり、両脚部３１，３２の間隙は、その最狭部が、ドアフレーム本体２の被取付部２７（下縁部２７１と上縁部２７２との積層部）の肉厚より若干狭くなるように形成されている。このため、被取付部２７にフレームモール３の両脚部３１，３２を外嵌した状態では、フレームモール３の両脚部３１，３２が、両脚の内側方向へ付勢されるバネ力によってドアフレーム本体２の被取付部２７をある程度の力で保持するため、作業性が良い。但し、その脱落を防止できるほどの力ではないため、スポット溶接が必要となる。スポット溶接用の孔３１０（図２）は、下側の脚部３１の適宜の部位（長手方向＝図１の紙面直交方向の、望ましくは複数箇所）に設けられている。
また、フレームモール３とドアフレーム本体２とは同じ鉄製であるため、異種金属接触時の電蝕の問題も発生しない。したがって、両者間に絶縁層を介在させる必要も無く、工数・コストの増加も回避できる。 The frame molding 3 is formed by bending a long iron plate made of the same material as the door frame main body 2 and thinner than the door frame main body 2, and the gap between the leg portions 31 and 32 is the narrowest portion. The door frame body 2 is formed so as to be slightly narrower than the wall thickness of the attached portion 27 (the laminated portion of the lower edge portion 271 and the upper edge portion 272). For this reason, in a state in which both the leg portions 31 and 32 of the frame molding 3 are externally fitted to the attached portion 27, the door frame main body is spring-biased by the both leg portions 31 and 32 of the frame molding 3 being urged inwardly of the both legs. Since the two attached portions 27 are held with a certain amount of force, workability is good. However, spot welding is necessary because the force is not strong enough to prevent the dropout. The spot-welding holes 310 (FIG. 2) are provided at appropriate portions (longitudinal direction = preferably a plurality of locations in the direction orthogonal to the plane of FIG. 1) of the lower leg portion 31.
Further, since the frame molding 3 and the door frame main body 2 are made of the same iron, there is no problem of electrolytic corrosion when contacting different metals. Therefore, there is no need to interpose an insulating layer between them, and an increase in man-hours and costs can be avoided.

フレームモール３の下脚部３１の先端には、上脚部３２との間隙が拡がる方向へ曲げられた下脚屈曲端部３３が形成されている。このため、両脚部３１，３２の開口部の間口が広くなり、上記の外嵌時には、嵌め易くて作業性が良い。また、ドアフレーム本体２の下縁部２７１の対応部位（上記下脚屈曲端部３３に対応する部位）には、下段部２３が形成されている。このため、上記の外嵌時には、フレームモール３の下脚部３１先端の下脚屈曲端部３３が、ドアフレーム本体２の下縁部２７１の下段部２３の位置（この位置はドアフレームの長さ方向（幅方向）で一定である）で確実に停止されることとなり、幅方向の取り付けバラツキも発生しない。   A lower leg bent end portion 33 is formed at the tip of the lower leg portion 31 of the frame molding 3 so as to be bent in a direction in which a gap with the upper leg portion 32 is widened. For this reason, the frontage of the opening part of both the leg parts 31 and 32 becomes wide, and it is easy to fit at the time of said external fitting, and workability | operativity is good. Further, a lower step portion 23 is formed at a corresponding portion of the lower edge portion 271 of the door frame main body 2 (a portion corresponding to the lower leg bent end portion 33). Therefore, at the time of the above-described external fitting, the lower leg bent end portion 33 at the tip of the lower leg portion 31 of the frame molding 3 is positioned at the lower step portion 23 of the lower edge portion 271 of the door frame body 2 (this position is the length direction of the door frame). (The width direction is constant)), and the mounting is not caused in the width direction.

フレームモール３の上脚部３２の先端部は、上方へ折り曲げられた上脚折返端部３４として形成されており、これにより、モールリテーナ部３２２が構成される。また、チャンネル部２１は、モール意匠部３０の意匠下縁部３０１からの折り返し部分と、下脚部３１と、ドアフレーム本体２のチャンネル下凹部２１１と、チャンネル上凹部２１２とにより構成される。   The distal end portion of the upper leg portion 32 of the frame molding 3 is formed as an upper leg folding end portion 34 that is bent upward, whereby a molding retainer portion 322 is configured. The channel portion 21 includes a folded portion from the design lower edge portion 301 of the molding design portion 30, a lower leg portion 31, a channel lower recess 211 of the door frame body 2, and a channel upper recess 212.

ドアフレーム本体２は、フレームモール３の素材より厚肉である鉄製の長尺状の板材をロールフォーミングで折り曲げ形成したものであり、ガラスラン５が嵌め入れられて装着されるチャンネル部２１と、ウエザストリップ５が嵌め入れられて装着されるリテーナ部２２１と、ドア閉時に於いて車体のドア開口縁１の側に当接される膨出部２５を有し、該膨出部２５の反対側（車外側）に於いてドアフレーム本体２の両縁部２７１，２７２が揃えて重ねられて、被取付部（フレームモール３が外嵌される部位）２７とされている。なお、膨出部２５は、ドア開口縁１側に設けられたドアオープニングウエザストリップ（不図示）を介して、ドア閉時に於いてドア開口縁１に当接される。
ドアフレーム本体２がこのような形状を成すため、フレームモール３に代えて同形状のステンレス製のフレームモールを用意することにより、当該ステンレス製のフレームモールをドアフレーム本体２に取り付けて成るドアフレームを製造できる。即ち、ドアフレーム本体２を、鉄製のフレームモール２と、ステンレス製のフレームモールとで共通化することができる。このため、ドアフレーム本体２の製造用の設備コスト（金型、ロールの駒、長尺状板材を所望の方向に曲げるための曲げ型、長尺状板材を所望の長さで切断するためのプレス型等等の設備コスト）を低減できる。したがって、型式が同じで車格が異なる複数種類の自動車のドアフレームを、非常に低コストで製造できる。 The door frame main body 2 is formed by bending a long iron plate material thicker than the material of the frame molding 3 by roll forming, and a channel portion 21 to which the glass run 5 is fitted and attached, A retainer portion 221 to which the weather strip 5 is fitted and mounted, and a bulge portion 25 that abuts on the side of the door opening edge 1 of the vehicle body when the door is closed, opposite to the bulge portion 25. On the side (the vehicle outer side), both edge portions 271 and 272 of the door frame main body 2 are aligned and overlapped to form an attached portion (a portion to which the frame molding 3 is fitted) 27. Note that the bulging portion 25 is brought into contact with the door opening edge 1 when the door is closed via a door opening weather strip (not shown) provided on the door opening edge 1 side.
Since the door frame body 2 has such a shape, a stainless steel frame molding having the same shape is prepared in place of the frame molding 3 so that the stainless steel frame molding is attached to the door frame main body 2. Can be manufactured. That is, the door frame body 2 can be shared by the iron frame molding 2 and the stainless frame molding. For this reason, the equipment cost for manufacturing the door frame main body 2 (mold, roll piece, bending die for bending the long plate material in a desired direction, and cutting the long plate material at a desired length Equipment cost such as a press die) can be reduced. Therefore, it is possible to manufacture a plurality of types of automobile door frames having the same model and different vehicle grades at a very low cost.

上記に於いて、チャンネル部２１のチャンネル下凹部２１１にはガラスラン４の下係止片４１１が嵌め入れられる。また、チャンネル部２１のチャンネル上凹部２１２にはガラスラン４の上係止片４１２が嵌め入れられる。また、チャンネル部２１の一部を成すようにフレームモール３により構成されるモールチャンネル凹部３１３には、ガラスラン４の外側係止片４１３が嵌め入れられる。なお、４０１は、フレームモール３のモール意匠部３０の下縁部を覆う車外側カバーリップである。また、４６１と４６２は、ドアガラス６が閉められた時に該ドアガラス６との間隙をシールするシールリップである。   In the above, the lower locking piece 411 of the glass run 4 is fitted into the channel lower recess 211 of the channel portion 21. Further, the upper locking piece 412 of the glass run 4 is fitted into the channel upper recess 212 of the channel portion 21. Further, the outer locking piece 413 of the glass run 4 is fitted into the molding channel recess 313 formed by the frame molding 3 so as to form a part of the channel section 21. Reference numeral 401 denotes a vehicle outer side cover lip that covers the lower edge portion of the molding part 30 of the frame molding 3. Reference numerals 461 and 462 denote seal lips that seal a gap with the door glass 6 when the door glass 6 is closed.

また、リテーナ部２２１には、ウエザストリップ５の下係止基部５２１が嵌め入れられる。また、リテーナ部の一部を成すようにドアフレーム本体２の上縁部２７２上に設けられるフレームモール３の上脚部３２等により構成されるモールリテーナ部３２２には、ウエザストリップ５の上係止基部５２２が嵌め入れられる。   The retainer portion 221 is fitted with a lower locking base portion 521 of the weather strip 5. In addition, the molding retainer portion 322 including the upper leg portion 32 of the frame molding 3 provided on the upper edge portion 272 of the door frame main body 2 so as to form a part of the retaining portion has an upper portion of the weather strip 5. A locking base 522 is fitted.

こうして、鉄製で厚肉ののドアフレーム本体２に鉄製で薄肉のフレームモールをスポット溶接で取り付けて構成されたドアフレームは、ドアフレーム全体として塗装されることにより、モール意匠部３０の表面が意匠面とされる。或いは、その表面にテープを貼着して、金属調の意匠面としてもよい。   In this way, the door frame constructed by spot welding the steel and thin wall molding to the thick and thick door frame main body 2 is painted as a whole door frame, so that the surface of the molding design portion 30 is designed. It is made a face. Or it is good also as sticking a tape on the surface and making it a metal-like design surface.

図１や２に示すドアフレームでは、フレームモール３は二つの脚部３１，３２を有するが、これに代えて、上側の脚部３２のみを有するフレームモールを用いた場合にも、鉄製のフレームモールとステンレス製のフレームモールとで、ドアフレーム本体を共通化することができる。なお、その場合、スポット溶接用の孔３１０は不要である。   In the door frame shown in FIGS. 1 and 2, the frame molding 3 has two leg portions 31 and 32. However, instead of this, even when a frame molding having only the upper leg portion 32 is used, an iron frame is used. The door frame body can be shared by the molding and the stainless steel molding. In this case, the spot welding hole 310 is not necessary.
