Description

本発明はロアフレームとメインフレームとの接合面を改良したドアフレームに関する。   The present invention relates to a door frame having an improved joint surface between a lower frame and a main frame.

ドアフレーム１は、図１に示すように、ウインドガラス（図示なし）の昇降を案内するセンターピラー２とロアフレーム３、所定の間隔にセンターピラー２とロアフレーム３とを維持させかつウインドガラスの上死点を画定するメインフレーム４とからなり、メインフレーム４の先端部とロアフレーム３との間にミラーブラケット５が配設される。   As shown in FIG. 1, the door frame 1 has a center pillar 2 and a lower frame 3 that guide the raising and lowering of the window glass (not shown), and maintains the center pillar 2 and the lower frame 3 at a predetermined interval. The mirror frame 5 is disposed between the front end portion of the main frame 4 and the lower frame 3.

図５を参照する。ロアフレーム３は断面略コの字状のもので車両の上下方向に延在する。ウインドガラスの縁はこのロアフレーム３の溝６に沿って昇降する。
メインフレーム４は、車体のドア開口部の上縁に沿う形状に成形されており、外部にさらされる意匠面７と、室内側に位置しかつ意匠面からは離間する中空部８とを有す。ロアフレーム３は、メインフレーム４の意匠面７と中空部８の室外側面との間に位置し、意匠面７とロアフレーム３との接合面には盛金即ち溶接９が施されている。この溶接即ち盛金（ビード）９はメインフレーム４とロアフレーム３との接合面の隙間をふさぎ、該隙間からの雨水の室内側への浸入を防止するとともに、隙間のない見栄えの良いドアを提供する。 Please refer to FIG. The lower frame 3 has a substantially U-shaped cross section and extends in the vertical direction of the vehicle. The edge of the window glass moves up and down along the groove 6 of the lower frame 3.
The main frame 4 is formed in a shape along the upper edge of the door opening of the vehicle body, and has a design surface 7 that is exposed to the outside and a hollow portion 8 that is located on the indoor side and is spaced apart from the design surface. . The lower frame 3 is positioned between the design surface 7 of the main frame 4 and the outdoor side surface of the hollow portion 8, and the metal plate, that is, welding 9 is applied to the joint surface between the design surface 7 and the lower frame 3. This weld, ie, bead 9, closes the gap between the joint surfaces of the main frame 4 and the lower frame 3, prevents rainwater from entering the indoor side through the gap, and provides a good-looking door with no gap. provide.

前述した隙間からの雨水の浸入は、ミラーブラケット５を通って室内につづくワイヤー等の錆の原因を作り好ましくなく、溶接９は不可欠の作業となっている。
しかし、該溶接作業は、溶接後の意匠面７と盛金９とをほぼ同平面とするために溶接による盛金９の研削と仕上加工が必要となっている。 The intrusion of rainwater from the gap described above is not preferable because it causes rust such as a wire that continues into the room through the mirror bracket 5 and welding 9 is an indispensable work.
However, the welding operation requires grinding and finishing of the metal plate 9 by welding in order to make the design surface 7 and the metal plate 9 after welding substantially the same plane.

実開平４−１２５９５４号公報Japanese Utility Model Publication No. 4-125595 特開２００２−３６８８０号公報JP 2002-36880 A

前述したように、盛金９を意匠面７とほぼ同平面とする研削と仕上加工は工数を要する作業にしては見栄えは必ずしも良好とは言えず、改善が望まれている。
それ故に、本発明は前述した従来技術の不具合を解消させることを解決すべき課題とする。 As described above, the grinding and finishing process in which the metal plate 9 is substantially flush with the design surface 7 does not always look good for work that requires man-hours, and improvements are desired.
Therefore, an object of the present invention is to solve the problems of the prior art described above.

本発明は、前述した従来技術の不具合を解消させるために、メインフレームとロアフレームとの接合面に熱硬化形シール材を用いる技術手段を採用する。
この手段の採用は、ドアフレームを塗装炉で処理中シール材を硬化させメインフレームとロアフレームとの隙間をふさぎながら両者を接合させることが可能であり、従来必要とした研削作業、これにつづく仕上作業が不用となり、作業工数が大幅に節減できる。加えて、メインフレームの意匠面とロアフレームの外表面との平滑性が保たれ、見栄えが向上し、シール性も良い。 The present invention employs technical means that uses a thermosetting sealing material on the joint surface between the main frame and the lower frame in order to eliminate the above-described problems of the prior art.
Adopting this method allows the door frame to be hardened while the door frame is being processed in the painting furnace, so that the gap between the main frame and the lower frame can be closed and joined together. Finishing work is not necessary, and work man-hours can be greatly reduced. In addition, the smoothness between the design surface of the main frame and the outer surface of the lower frame is maintained, the appearance is improved, and the sealing property is good.

本発明によれば、ウインドガラスの昇降を案内する溝を有しかつ離間対向して配されるセンターピラーおよびロアフレームと、側縁がセンターピラーおよびロアフレームの外表面の端縁と所定の隙間をもって突合せ結合される意匠面を有しかつウインドガラスの上死点を画定するメインフレームとを有するドアフレームにおいて、メインフレームの意匠面と外表面とに隙間をふさぐように装着される熱硬化形シール材を有し、該シール材がアルミニウム合金材又はスチール材よりなる薄板と薄板の裏面に配され外表面及び意匠面に装着される接着層とからなることを特徴とするドアフレームが提供される。 According to the present invention, the center pillar and the lower frame that have the groove for guiding the raising and lowering of the window glass and that are spaced apart from each other, and the side edges of the center pillar and the lower frame are separated from the edges of the outer surface of the center pillar and the lower frame. The door frame has a design surface that is butt-joined and has a main frame that defines the top dead center of the wind glass, and is mounted on the design surface and the outer surface of the main frame so as to close a gap. There is provided a door frame comprising a sealing material, the sealing material comprising a thin plate made of an aluminum alloy material or a steel material and an adhesive layer disposed on the back surface of the thin plate and attached to the outer surface and the design surface. The

ドアフレームのメインフレームとロアフレームとの接合面の隙間を熱硬化形シール材によりふさぎ平滑性を確保しかつ雨水の浸入を防ぐ手段は、溶接による該隙間をふさぐ手段に比し、研削や加工作業が不用となり作業工数を大幅に削減できる。又、雨水の隙間からの浸入を完全にふさぎ、室内につづく部品等の錆の発生を防止できる。
加えて、意匠面とロアレール外表面とを面一の平坦な面としてつなぎ、シール材のへこみが無く見栄えがよい。 The gap between the joint surfaces of the door frame main frame and the lower frame is covered with a thermosetting sealant to ensure smoothness and prevent rainwater from entering, compared to the means for closing the gap by welding. The work is unnecessary and the work man-hours can be greatly reduced. In addition, it is possible to completely block the intrusion from the gap of rainwater, and to prevent the occurrence of rust on parts that continue in the room.
In addition, the design surface and the outer surface of the lower rail are connected as a flat surface so that the seal material does not have a dent and looks good.

ドアフレーム１は、図１に示すように、ウインドガラス（図示なし）の昇降を案内するセンターピラー２とロアフレーム３、所定の間隔にセンターピラー２とロアフレーム３とを維持させかつウインドガラスの上死点を画定するメインフレーム４とからなり、メインフレーム４の先端部とロアフレーム３との間にミラーブラケット５が配設される。   As shown in FIG. 1, the door frame 1 has a center pillar 2 and a lower frame 3 that guide the raising and lowering of the window glass (not shown), and maintains the center pillar 2 and the lower frame 3 at a predetermined interval. The mirror frame 5 is disposed between the front end portion of the main frame 4 and the lower frame 3.

メインフレーム４の意匠面とロアフレーム３の外表面との間の隙間１０をふさぐべく熱硬化形シール材１１を装着する。
熱硬化形シール材１１は、図３に示すように、アルミニウム合金材又はスチール材の薄板１２と、薄板１２の両側に離間して配される熱硬化テープ１３，１３とからなる。熱硬化テープ１３，１３は、たとえば商品名 熱硬化アクリルフォームテープ（３Ｍ製 品番 4761S）を用いることができる。 A thermosetting sealing material 11 is mounted so as to close a gap 10 between the design surface of the main frame 4 and the outer surface of the lower frame 3.
Thermosetting type sealing member 11, as shown in FIG. 3, a thin plate 12 of an aluminum alloy material or steel material, consisting of thermosetting tape 13, 13 Metropolitan which is disposed spaced on opposite sides of the thin plate 12. As the thermosetting tapes 13, 13, for example, a trade name thermosetting acrylic foam tape (3M product number 4761S) can be used.

シール材１１は、図４に示すように、基板としての薄板１２の裏面一様に熱硬化テープ１３を粘着したものでも良い。
シール材１１は、熱硬化テープ１３を、メインフレーム４の意匠面７とロアフレーム３の外表面とに接着し、隙間１０をふさぐ。熱硬化テープ１３は厚み０．３mmと薄く、又、基板としての薄板１２の厚みも１mm以下とすれば、シール材１１の意匠面７からの張り出しもなく、平滑度が保たれる。 As shown in FIG. 4, the sealing material 11 may be one in which a thermosetting tape 13 is adhered uniformly on the back surface of a thin plate 12 as a substrate.
The sealing material 11 adheres the thermosetting tape 13 to the design surface 7 of the main frame 4 and the outer surface of the lower frame 3 to close the gap 10. If the thermosetting tape 13 is as thin as 0.3 mm, and if the thickness of the thin plate 12 as a substrate is also 1 mm or less, the projecting surface 7 of the sealing material 11 does not protrude and the smoothness is maintained.

ドアフレーム１への塗装を完了し、ドアフレーム１が塗装炉に入ると、シール材１１はその熱を受け、軟化しながら、メインフレーム４の意匠面７とロアフレーム３の外表面に接着する。その際、薄板１２が軟化した熱硬化テープ１３のたれを防ぎ、必要なシール面と平滑度を確保する。   When the coating on the door frame 1 is completed and the door frame 1 enters the coating furnace, the sealing material 11 receives the heat and softens while adhering to the design surface 7 of the main frame 4 and the outer surface of the lower frame 3. . At that time, the thinned sheet 12 is prevented from sagging the thermosetting tape 13 and the necessary sealing surface and smoothness are ensured.

図示例では、ドアフレームのメインフレームとロアフレームとの接合面即ち継ぎ目の隙間のシールについて述べたが、本発明はドアフレームの他の部分や車両のボデーなどの隙間がありかつ平らな面を作る二部材間のシール材としても利用できる。   In the illustrated example, the seal between the joint surface of the main frame and the lower frame of the door frame, that is, the gap of the joint, has been described. However, the present invention provides a flat surface with a gap such as other parts of the door frame or the body of the vehicle. It can also be used as a sealing material between two members to be made.
