【０００１】
【発明の属する技術分野】
本発明はバックドアハンドルの仮組み構造に関する。詳しくは、車両のバックドアに取り付けられるバックドアハンドルの仮組みにおいて、構成部品と組み付け工数を減らし、且つ防水性を確保可能としたバックドアハンドルの仮組み構造に関する。
【０００２】
【従来の技術】
車両のバックドアに取り付けられるバックドアハンドルは、ドアの外板にボルトにより固定されている。このため、その取り付けにはドア外板に穿設したボルト孔から雨水、洗浄水などが侵入しないように防水機構を設ける必要がある。図３及び図４は従来のバックドアハンドルの１例を示す図で、図３（ａ）は正面図、図３(ｂ）は図３（ａ）のｂ−ｂ線における断面図、図４（ａ）は図３(ｂ）のＣ部拡大分解斜視図、図４(ｂ）は図４（ａ）の組立て後の断面図である。両図において、符号１はバックドアハンドル本体、２はバックドアパネル、３はガーニッシュ（飾り板）、４は結合ボルト、５は防水用のスポンジである。このスポンジ５は図４（ａ）に示すように、そのボルト孔５ａの内径Ａは結合ボルト４の軸径Ｂよりも小さく形成されている。
【０００３】
そして、図３の如くバックドアハンドル本体１にはボルト孔１ａが穿設され、バックドアパネル２及びガーニッシュ３にもボルト孔２ａ、３ａが穿設されている。そして、結合ボルト４を、ガーニッシュ３のボルト孔３ａ、バックドアハンドル本体１のボルト孔１ａ、スポンジ５の孔５ａを順次挿通する。この状態で、スポンジ５の孔５ａが結合ボルト４の外径より小さく形成されているため、結合ボルト４の抜け止めとなり、バックドアハンドル本体１はガーニッシュ３に仮止めされることになる。その後、結合ボルト４をバックドアパネル２のボルト孔２ａに挿通して、図４（ｂ）の如くナット６により締め付け固定するのである。
【０００４】
【発明が解決しようとする課題】
上記のような従来のバックドアハンドルの仮組み構造においては、図４（ｂ）の如く、スポンジ５を潰してシールしているため、熱によりスポンジ５がへたり、結合ボルト４の締め付けが緩むという問題がある。また、構成部品が増えるためコストアップとなる。また、スポンジ貼付け位置のバラツキが大きく品質が安定しない。また、ガーニッシュ３との仮組みに限られてしまう等の問題があった。
【０００５】
本発明は、上記従来の問題点に鑑み、構成部品と組付け工数を減らし、且つ、防水性を確保可能としたバックドアハンドルの仮組み構造を実現することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、本発明の請求項１のバックドアハンドルの仮組み構造は、車両のバックドアパネルにボルトにより取り付けられるバックドアハンドルにおいて、バックドアハンドル本体（１０）を硬質材（Ａ）と軟質材（Ｂ）の２種類の樹脂にて２色射出成形し、前記バックドアパネル（１１）に穿設されたバックドアハンドル取付け用の窓部の縁部に係合する仮止め用の突起（１４）を前記軟質材（Ｂ）に形成し、前記ボルト孔（１３）の周囲にシール用リブ（１５）を前記軟質材（Ｂ）に形成したことを特徴とする。
また、請求項２は、上記バックドアパネル（１１）に穿設されたバックドアハンドル取り付け用の窓部の周辺に接する上記軟質材（Ｂ）に、シール用のリブ（１６）を形成したことを特徴とする。
【０００７】
この構成を採ることにより、仮止め用の突起１４によりバックドアパネルへの仮組み付けが容易となり、従来のスポンジが不用となるため構成部品及び組付け工数が減少する。また、ボルト孔１３の周囲に形成したシール用のリブ１５、及びバックドアパネル１１に穿設されたバックドアハンドル取り付け用の窓部の周辺に接する部分に形成したシール用のリブ１６により防水性が確保可能となる。
【０００８】
【発明の実施の形態】
図１及び図２は本発明のバックドアハンドルの仮組み構造の実施の形態を示す図で、図１（ａ）はバックドアハンドル本体の斜視図、図１（ｂ）は正面図、図１（ｃ）は図１（ｂ）のｃ−ｃ線における断面図、図２（ａ）は図１（ｃ）のＤ部拡大図、図２（ｂ）は図１（ｃ）のＥ部拡大図である。図１及び図２において、符号１０はバックドアハンドル本体、１１はバックドアパネル、１２はガーニッシュである。
【０００９】
前記バックドアハンドル本体１０は、左右にボルト孔１３を有し、硬質の樹脂と軟質の樹脂で２色射出成形されている。即ち、図１（ａ）の斜視図において、ハッチングを施してある部分（バックドアパネルに接する本体の矩形部分及びボルト孔周辺を含む部分）を軟質材Ｂで、ハッチングを施してない部分を硬質材Ａで２色射出成形している。なお、軟質材Ｂはシール構造を形成するため硬度４０前後が好ましい。
【００１０】
そして、バックドアハンドル本体１０には、図１及び図２（ａ）に示すように、バックドアパネル１１に設けられた窓部の縁部に、仮組み時に係合させる係合突起１４が形成されている。また、図２（ｂ）の如く、軟質材Ｂで形成した部分のボルト孔１３の周囲にシール用のリブ１５が二重のリング状に形成されている。また図２（ａ）の如く、バックドアパネル１１に設けられた窓部の周辺に接する部分にもシール用のリブ１６が２本の平行線状に形成されている。
【００１１】
このように構成された本実施の形態は、バックドアハンドル本体１０を硬質材と軟質材で２色射出成形し、その軟質材に仮組み用の係合突起１４を形成したことによりバックドアパネルへの仮組みが容易となり、また、シール用のリブ１５，１６を形成したことにより、スポンジを用いずとも防水性を確保することができ、構成部品と組付け工数を減らすことができる。
【００１２】
【発明の効果】
本発明のバックドアハンドルの仮組み構造に依れば、バックドアハンドル本体を樹脂の硬質材と軟質材で２色射出成形しその軟質材に仮組み用の係合突起と、シール用のリブとを設けたことにより、構成部品と組付け工数を減らし、且つ、防水性を確保することが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a temporary assembly structure of a back door handle. More specifically, the present invention relates to a temporary assembly structure of a back door handle that can reduce the number of components and the number of assembling steps and can ensure waterproofness in a temporary assembly of a back door handle attached to a back door of a vehicle.
[0002]
[Prior art]
A back door handle attached to the back door of the vehicle is fixed to the outer plate of the door with bolts. For this reason, it is necessary to provide a waterproof mechanism so that rainwater, washing water and the like do not enter from the bolt holes drilled in the door outer plate. 3 and 4 are views showing an example of a conventional back door handle, FIG. 3 (a) is a front view, FIG. 3 (b) is a cross-sectional view taken along the line bb of FIG. 3 (a), and FIG. FIG. 4A is an enlarged exploded perspective view of a portion C in FIG. 3B, and FIG. 4B is a cross-sectional view after assembly in FIG. In both figures, reference numeral 1 is a back door handle body, 2 is a back door panel, 3 is a garnish (decorative board), 4 is a coupling bolt, and 5 is a waterproof sponge. As shown in FIG. 4A, the sponge 5 is formed such that the inner diameter A of the bolt hole 5 a is smaller than the shaft diameter B of the coupling bolt 4.
[0003]
As shown in FIG. 3, the back door handle main body 1 is provided with bolt holes 1a, and the back door panel 2 and the garnish 3 are also provided with bolt holes 2a and 3a. Then, the coupling bolt 4 is inserted through the bolt hole 3a of the garnish 3, the bolt hole 1a of the back door handle body 1, and the hole 5a of the sponge 5 in this order. In this state, since the hole 5 a of the sponge 5 is formed smaller than the outer diameter of the coupling bolt 4, the coupling bolt 4 is prevented from coming off, and the back door handle body 1 is temporarily secured to the garnish 3. Thereafter, the connecting bolt 4 is inserted into the bolt hole 2a of the back door panel 2, and is fastened and fixed by the nut 6 as shown in FIG. 4 (b).
[0004]
[Problems to be solved by the invention]
In the conventional temporarily assembled structure of the back door handle as described above, since the sponge 5 is crushed and sealed as shown in FIG. 4B, the sponge 5 sags due to heat and the coupling bolt 4 is loosened. There is a problem. In addition, the number of components increases, resulting in an increase in cost. In addition, the quality of the sponge is not stable due to large variations in the position where the sponge is applied. In addition, there are problems such as being limited to temporary assembly with the garnish 3.
[0005]
In view of the above-described conventional problems, an object of the present invention is to realize a temporary assembly structure of a back door handle that can reduce component parts and assembly man-hours and can ensure waterproofness.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to a temporary assembly structure of a back door handle according to claim 1 of the present invention , the back door handle main body (10) is made of a hard material (A) in a back door handle attached to a back door panel of a vehicle by bolts. Two-color injection molding using two types of resin, soft material (B), and a temporary fixing protrusion that engages with the edge of the back door handle mounting window bored in the back door panel (11) (14) is formed on the soft material (B), and a sealing rib (15) is formed on the soft material (B) around the bolt hole (13).
According to a second aspect of the present invention, a sealing rib (16) is formed on the soft material (B) in contact with the periphery of the window portion for attaching the back door handle formed in the back door panel (11). Features.
[0007]
By adopting this configuration, the temporary attachment to the back door panel is facilitated by the temporary fixing projections 14, and the conventional sponge is not required, so that the components and assembly man-hours are reduced. Further, the sealing ribs 15 formed around the bolt holes 13 and the sealing ribs 16 formed on the portion of the back door panel 11 in contact with the periphery of the window portion for attaching the back door handle are waterproof. It can be secured.
[0008]

(C) is a cross-sectional view taken along the line cc of FIG. 1 (b), FIG. 2 (a) is an enlarged view of a D portion of FIG. 1 (c), and FIG. 2 (b) is an enlarged view of an E portion of FIG. FIG. 1 and 2, reference numeral 10 denotes a back door handle body, 11 denotes a back door panel, and 12 denotes a garnish.
[0009]
The back door handle body 10 has bolt holes 13 on the left and right sides, and is two-color injection molded with a hard resin and a soft resin. That is, in the perspective view of FIG. 1A, the hatched part (the rectangular part of the main body that touches the back door panel and the part including the periphery of the bolt hole) is made of the soft material B, and the part not hatched is made of the hard material. Two-color injection molding is performed with A. The soft material B preferably has a hardness of around 40 in order to form a seal structure.
[0010]
As shown in FIGS. 1 and 2A, the back door handle main body 10 is formed with an engaging protrusion 14 that is engaged with the edge of the window provided on the back door panel 11 during temporary assembly. ing. Further, as shown in FIG. 2B, sealing ribs 15 are formed in a double ring shape around the bolt hole 13 in the portion formed of the soft material B. Further, as shown in FIG. 2A, sealing ribs 16 are formed in two parallel lines at a portion in contact with the periphery of the window provided on the back door panel 11.
[0011]
In this embodiment configured as described above, the back door handle body 10 is two-color injection-molded with a hard material and a soft material, and the engagement protrusions 14 for temporary assembly are formed on the soft material, whereby the back door panel is formed. In addition, since the sealing ribs 15 and 16 are formed, waterproofness can be secured without using a sponge, and the number of component parts and assembly steps can be reduced.
