【発明の詳細な説明】 ≪発明の技術分野≫ この発明は、ミラー付サンバイザの製造方法に
関する。
≪従来技術とその問題点≫ ミラー付サンバイザとして、従来第４図に示す
構造のものがある。
このサンバイザは、ワイヤ芯材１の裏面および
表面にパツド材２，３を挾んで表皮材４，５を積

保持したミラーケース６を嵌め付けるための開口
が形成されており、また表面側表皮材５は、ミラ
ーケース６の内周縁に高周波ウエルダにより溶着

ミラー８の周縁を縁取るための方法としては、
第５図ａ，ｂに示すように、高周波ウエルダ装置
の下型１０上にミラーケース６を設置し、その上
面に表皮材５を被せた状態で高周波ウエルダ電極
１１をミラーケース６の内側フランジ部分に向け
て押圧し、下型１０および高周波ウエルダ電極１
１間で両者を挾みつけた状態で融着を行う。
次いで、融着を行つた後に表皮材５の内側部分
を高周波ウエルダによつて形成された薄肉部分７
に沿つて切り取り、窓を開けるようにしている。
そして、次工程でミラー８の外周部をミラーケ
ース６に嵌め付けるようにしている。
しかしながら、ミラーケース６は塩化ビニール
等の軟質樹脂の射出成形体からなつており、また
表皮材５は同様に塩化ビニールからなつているた
めに、第５図ｂに示すように切り離した部分が加
熱収縮力またはミラーケース６の耐熱剛性不足に
よつてめくれ上がつてしまい、ミラー８とミラー
ケース６との間にめくり上がりによる隙間Ｓが発
生する。またこの隙間Ｓはミラー８によつて映し
出されるために、外観上はその映し出された虚像
が見えることになるので、隙間Ｓが２倍の値とな
つて見え、商品性が低下する欠点があつた。
≪発明の目的≫ この発明は、ミラーの周縁部とミラーケース内
周縁との間に以上のような隙間の発生することを
防止し、商品性を向上させることを目的とする。
≪発明の構成と効果≫ 前記目的を達成するために、この発明は、高周
波ウエルダ装置の型面上に設置されたミラーの周
縁に、高周波接着用の接着媒体を介してミラーケ

置し、ミラーケースの内周形状に形成した高周波
ウエルダ電極を表皮材上に押し当て、高周波を印
加することで、ミラーとミラーケースおよび表皮
材の３者を一体に融着し、次いで高周波ウエルダ
電極の内周に設けたカツト刃を表皮材に押し付け

て切り離し可能としたことを特徴とする。
以上の方法によれば、高周波ウエルダ時にミラ
ーをミラーケースに一体に融着し、その後、カツ
ト刃で付着の内周部に生じた表皮材の端材を切り
離し可能に押し切るするようになつているので、
端材を切り取つた後に、切り取つた部分に隙が発
生することがなく、商品性が向上する。
また、この発明では、ミラーケースの表皮に対
する接着と同時にミラーケース内にミラーを固定
できるので、工数も省くことができる。
≪発明の実施例≫ 第１図はこの発明を適用した高周波ウエルダ装
置を示すものである。
図において、２１，２２は高周波発振器２０に
接続された型板である。
各型板２１，２２はそれぞれガイドポスト２
３，２４によつて離接可能にガイドされる。
下側型板２１上には下型２５が設置されてお
り、下型２５に対向して上側型板２２の下面には
高周波ウエルダ電極２６が対向設置されている。
さらに、高周波ウエルダ電極２６の内周部にはカ
ツト刃２７が配置されている。
そして、カツト刃２７は通常状態ではウエルダ
電極２６の下端よりも高い位置に設置され、高周
波ウエルダ加工後に下部に突出する構造となつて
いる。
第２図はウエルダ電極２６およびカツト刃２７
の要部を示すもので、電極２６は型板２２に固定
されたブラケツト２２ａおよびカツト刃２７間に
昇降可能に保持され、かつ電極２６の上端と、型
板２２間に介在された弾性体２２ｂにより、下端
がカツト刃２７の下端より突出した状態に保持さ

したがつて電極２６が下型２５に当接した後、
更に型板２２を下降させると電極２６は弾性体２
２ｂを圧してその位置に保持され、相対的にカツ
ト刃２７が下降することになる。
次に、以上の構成の高周波ウエルダ装置を用い
たウエルダ方法について説明する。
まず、第１図に示すように下型２５上に周縁に
ミラーケース２５を装着したミラー３０を設置す
る。次いでその上面を表皮材３４で覆う。
なお、ミラーの周縁とミラーケース３２との接
着面間には高周波ウエルダ助剤３６を介在してお
く。
高周波ウエルダ助剤は、EVA系、ウレタン系、
NBR等の耐熱性のある接着剤であつて、たとえ
ばミラー外周部にウエルダ助剤３６を形成する場
合には、シルク印刷等により塗布を行う。
またミラーケース３２の裏面にも同様の方法で
ウエルダ助剤３６を塗布しておく。
なお、ウエルダ助剤３６はミラー３０かミラー
ケース３２のいずれか一方に塗布しておいてもよ
い。
以上のセツテイング操作終了後に、上側型板２
２を下降させ、第３図ａに示すように高周波ウエ
ルダ電極２６を表皮材３４の表面に押し当て、次
いで高周波発振器を発振させ、両者間を加熱溶着
する。
この状態で、ミラー３０とミラーケース３２間
は高周波ウエルダ助剤３６の溶融により完全に接
着し、またミラーケース３２と表皮材３４間は自
身の加熱により一体に融着する。
次に、この状態を保持したまま発振を停止し、
更に型板２２を下降させることにより第３図ｂに
示すようにカツト刃２７が下降し、ウエルダ部分
４０の内周部にカツト刃２７の先端を当てる。
以上の動作終了後に型板２２を引き上げ、完成
品を下型２５上から取出し、カツト刃２７によつ
て薄肉化された部分４０を基点に、表皮材３４の
端材３４′を引きはがせば、第３図ｃに示すよう
にミラー３０とミラーケース３２および表皮材３
４が一体となつたものを得られる。
そして、得られたもののカツト部分は高周波ウ
エルダ助剤３６によつてミラー３０に密着した状
態となつており、明瞭なふどりとなる。
そして、このように構成された素材を用いて第
４図の従来に示すような断面形状のサンバイザが
組上がることになる。
なお、前記実施例では高周波接着用の接着媒体
として耐熱性のある高周波ウエルダ助剤を用いた
が、たとえばホツトメルトフイルムを介して接着
を行うようにしてもよい。
