本発明は自動車のドアミラー取付用ブラケツト
の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a bracket for mounting an automobile door mirror.
従来、車外のバツクミラーはフロントフエンダ
の前部に取付けられる場合が多かつたが、最近で
はフロントドアに取付ける形式のものが増加して
いる。
Conventionally, rearview mirrors outside the vehicle have often been attached to the front of the front fender, but recently more and more rearview mirrors are attached to the front door.
このバツクミラー（ドアミラー）は第１図に示
すようにフロントドア１のウエストライン１１の
前端隅角にブラケツト２を設け、これに取付けら
れる。 This back mirror (door mirror) is attached to a bracket 2 provided at the front end corner of the waist line 11 of the front door 1, as shown in FIG.
第２図および第６図に示すようにブラケツト２
は断面Ｕ字形のインサート板３をゴムまたは軟質
合成樹脂部材４で被覆した構造にになつており、
インサート板３の一方の辺は被覆部材４から下方
へ延出しており、この延出部３１によりドア１本
体のプレートに固定される。そしてドアガラス６
はその前縁部がブラケツト２の中心の溝２０内を
上下動する。このときブラケツト２の開口で対向
するリツプ４１はドアガラス６の面にに摺接す
る。 Bracket 2 as shown in Figures 2 and 6.
has a structure in which an insert plate 3 having a U-shaped cross section is covered with a rubber or soft synthetic resin member 4,
One side of the insert plate 3 extends downward from the covering member 4, and is fixed to the plate of the main body of the door 1 through this extending portion 31. and door glass 6
The front edge of the bracket 2 moves up and down in a groove 20 in the center of the bracket 2. At this time, the lip 41 facing the opening of the bracket 2 comes into sliding contact with the surface of the door glass 6.
このブラケツト２を製造する方法としては一般
に、第４図に示すように上下の型７ａ，７ｂより
なる成形型７のキヤビテイ内に中芯型８を設け、
これ等成形等７および中芯型８間に断面Ｕ字形の
キヤビテイ９を形成し、これに同じく断面Ｕ字形
のインサート板３をセツトし、該キヤビテイ９に
ゴムまたは軟質合成樹脂の被覆部材４を注入する
方法がとられている。 Generally, the method for manufacturing this bracket 2 is to provide a core mold 8 in the cavity of a mold 7 consisting of upper and lower molds 7a and 7b, as shown in FIG.
A cavity 9 having a U-shaped cross section is formed between these moldings 7 and the core mold 8, an insert plate 3 having a U-shaped cross section is set therein, and a covering member 4 made of rubber or soft synthetic resin is applied to the cavity 9. An injection method is used.
ところで、ブラケツト２の両リツプ４１間の開
口幅は自由状態においてドアガラス６の厚さ（通
常は３〜５mm）よりも充分に狭くしてシール性を
良好にすることが風切音発生を防止する上で望ま
れる。
By the way, wind noise can be prevented by making the opening width between both lips 41 of the bracket 2 in the free state sufficiently narrower than the thickness of the door glass 6 (usually 3 to 5 mm) to ensure good sealing performance. desired in doing so.
一方、中芯型８は一般に鋼製でその基端８１が
成形型７により片持ち式に支持せしめられてお
り、基端の強度を確保するためには最低1.5mmの
厚さが必要である。しかもインサート板３の外周
に形成されたゴムまたは合成樹脂材４は成形後、
開口幅を広げるように収縮するから基端厚さを
1.5mmとしてもリツプ４１間の開口幅は２〜2.5mm
程度になつてしまう。この開口幅ではガラスに対
して充分なシール性が得られない。 On the other hand, the core mold 8 is generally made of steel, and its base end 81 is supported in a cantilevered manner by the mold 7, and a thickness of at least 1.5 mm is required to ensure the strength of the base end. . Moreover, the rubber or synthetic resin material 4 formed on the outer periphery of the insert plate 3 is
It contracts to widen the opening width, so the proximal thickness is reduced.
Even if it is 1.5 mm, the opening width between the lips 41 is 2 to 2.5 mm.
It gets to a point. With this opening width, sufficient sealing performance against glass cannot be obtained.
そこで本発明は、片持式に支持される中芯型８
の基端８１の厚さを強度上充分な厚さとし、かつ
得られるブラケツトの両リツプ４１間の開口幅を
充分に狭くしてガラス面とのシール性を良好とす
ることができるブラケツトの製造方法を提供し、
もつて従来の問題点を解決することを目的とする
ものである。 Therefore, the present invention provides a core type 8 supported in a cantilevered manner.
A method for manufacturing a bracket in which the thickness of the base end 81 of the bracket is sufficiently thick in terms of strength, and the opening width between both lips 41 of the resulting bracket is sufficiently narrowed to provide good sealing performance with the glass surface. provide,
The aim is to solve the problems of the conventional technology.
本発明はインサート板として、バネ性を有する
板材よりなり、第３図に示すようにＵ字形の開口
側を狭くしたインサート板３を用い、第４図に示
すように成形型７のキヤビテイ９にセツトすると
きに両開口端３１がバネ力に抗して押広げられ中
芯型８を挟み付けるようになし、このようにして
インサート板３がセツトされたキヤビテイ９内に
ゴム等の被覆材４を注入することを特徴とする。
The present invention uses, as an insert plate, an insert plate 3 made of a plate material having spring properties and having a U-shaped opening narrowed as shown in FIG. When setting, both open ends 31 are pushed apart against the spring force so as to sandwich the core mold 8, and a covering material 4 such as rubber is inserted into the cavity 9 in which the insert plate 3 is set. It is characterized by injecting.
得られたブラケツト成形体を取出すと、インサ
ート板３の形状復元力により両開口端３１が接近
し、これに伴なつてブラケツト２も変形してその
リツプ４１も口を閉じじるように接近する。
When the obtained bracket molded body is taken out, both open ends 31 approach each other due to the shape restoring force of the insert plate 3, and accordingly, the bracket 2 is also deformed and its lips 41 also approach each other so as to close their mouths. .
従つて、中芯型８の基端８１を薄くすることな
く、リツプ４１とガラス面とのシール性を良好に
することができる。 Therefore, the sealing performance between the lip 41 and the glass surface can be improved without making the base end 81 of the core mold 8 thin.
本発明のブラケツト製造方法の実施例を第２図
ないし第５図により説明する。
An embodiment of the method for manufacturing a bracket according to the present invention will be explained with reference to FIGS. 2 to 5.
第４図に示すように上型７ａ、下型７ｂよりな
る成形型７内に中芯型８を支持せしめ、両型７
ａ，７ｂの間に、三角形状で断面Ｕ字形のキヤビ
テイ９を形成する。中芯型８はその基端８１が型
７ａ，７ｂ間に支持せしめてある。Ｕ字形キヤビ
テイ９の両先端はリツプ状に先細りとしてある。 As shown in FIG. 4, a core mold 8 is supported in a mold 7 consisting of an upper mold 7a and a lower mold 7b.
A triangular cavity 9 having a U-shaped cross section is formed between a and 7b. The base end 81 of the core mold 8 is supported between the molds 7a and 7b. Both ends of the U-shaped cavity 9 are tapered into lip shapes.
インサート板３は金属板の他、耐熱性とバネ性
を有する合成樹脂板よりなり、上半部は断面Ｕ字
形の三角形の板で、下半部は上半部の一辺を延出
せしめた三角形の延出部３１（第２図）としてあ

Ｕ字形上半部は第３図に示すように対向間隔が開
口側へ狭くなる形状で、開口端３１を押し広げて
中芯型８を包むように配しバネ力で中芯型８を挟
圧せしめた状態で中芯型８に保持せしめことによ
りキヤビテイ９内にセツトする。 The insert plate 3 is made of a heat-resistant and springy synthetic resin plate in addition to a metal plate.The upper half is a triangular plate with a U-shaped cross section, and the lower half is a triangular plate with one side of the upper half extending. The upper half is set in the cavity 9 as an extension part 31 (FIG. 2).
As shown in Fig. 3, the U-shaped upper half has a shape in which the opposing interval narrows toward the opening side, and the opening end 31 is pushed out and placed so as to wrap around the core mold 8, and the core mold 8 is compressed by the spring force. It is set in the cavity 9 by holding it in the center core mold 8 in the tightened state.
このようにしてインサート板３の上半部がセツ
トされたキヤビテイ９内にゴムまた軟質合成樹脂
の被覆部材４を注入し、開型することにより第２
図および第５図に示すようなブラケツトが得られ
る。 The coating member 4 made of rubber or soft synthetic resin is injected into the cavity 9 in which the upper half of the insert plate 3 is set in this way, and the second mold is opened.
A bracket as shown in FIGS. and FIG. 5 is obtained.
このブラケツト２では、インサート板３にはそ

し、これに伴なつてブラケツト全体も変形して被
覆部材４のリツプ４１の間隔は中芯型８の基端８
１の厚さよりも小さくなる。 In this bracket 2, a shape restoring force acts on the insert plate 3 as its tip 31 approaches, and the entire bracket also deforms accordingly, and the spacing between the lips 41 of the covering member 4 is reduced to the center core type 8. proximal end 8
The thickness is smaller than 1.
従つて本発明では、ブラケツトを型成形すると
き、強度的に充分な厚さの中芯型を用い、かつド
アガラスを挟むリツプ間の間隔が中芯型の厚さに
規制されることなく充分に小さいドアミラー取付
用ブラケツトを得ることができる。 Therefore, in the present invention, when molding the bracket, a core mold with sufficient thickness is used in terms of strength, and the distance between the lips that sandwich the door glass is not restricted by the thickness of the core mold, but is sufficiently thick. You can get a small door mirror mounting bracket.
