【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。DETAILED DESCRIPTION OF THE INVENTION <<Technical Field of the Invention>> The present invention relates to a method of manufacturing a sun visor with a mirror.

≪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。<<Prior Art and its Problems>> There is a conventional sun visor with a mirror having the structure shown in FIG.

このサンバイザは、ワイヤ芯材１の裏面および

る。 In this sun visor, skin materials 4 and 5 are laminated on the back and front surfaces of a wire core material 1 with pad materials 2 and 3 interposed therebetween, and the peripheral edges are adhered in a bag shape using high frequency welding to form a sun visor main body. The pad material 3 on the front side is formed with an opening for fitting the mirror 8 and the mirror case 6 holding the peripheral edge of the mirror 8, and the front skin material 5 is provided with a high-frequency wave on the inner peripheral edge of the mirror case 6. It is welded by a welder and frames the outer periphery of the mirror 8.

ミラー８の周縁を縁取るための方法としては、

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。 As a method for edging the periphery of the mirror 8,
As shown in FIGS. 5a and 5b, the mirror case 6 is installed on the lower mold 10 of the high-frequency welding device, and the high-frequency welding electrode 11 is attached to the inner flange part of the mirror case 6 with the skin material 5 covering the upper surface of the mirror case 6. the lower die 10 and the high frequency welder electrode 1.
Fusion is performed with both parts sandwiched between the two parts.

次いで、融着を行つた後に表皮材５の内側部分

に沿つて切り取り、窓を開けるようにしている。 Next, after fusion bonding, the inner part of the skin material 5 is attached to a thin part 7 formed by high frequency welding.
I cut it out along the lines to open the window.

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。 Then, in the next step, the outer peripheral portion of the mirror 8 is fitted into the mirror case 6.

しかしながら、ミラーケース６は塩化ビニール

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。 However, since the mirror case 6 is made of an injection molded product of a soft resin such as vinyl chloride, and the skin material 5 is also made of vinyl chloride, the separated portion is heated as shown in Fig. 5b. The curling force or insufficient heat-resistant rigidity of the mirror case 6 causes the mirror to curl up, and a gap S is generated between the mirror 8 and the mirror case 6 due to the curling up. In addition, since this gap S is reflected by the mirror 8, the projected virtual image is visible from the outside, so the gap S appears to be twice the value, which has the disadvantage of reducing marketability. Ta.

≪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。<<Object of the Invention>> The object of the present invention is to prevent the above-mentioned gap from occurring between the peripheral edge of the mirror and the inner peripheral edge of the mirror case, and to improve marketability.

て切り離し可能としたことを特徴とする。<<Structure and Effects of the Invention>> In order to achieve the above-mentioned object, this invention installs a mirror case on the periphery of the mirror installed on the mold surface of a high-frequency welding device via an adhesive medium for high-frequency bonding, A skin material trimmed along the outer shape of the sun visor is installed on the surface of the mirror case, and a high frequency welder electrode formed in the shape of the inner periphery of the mirror case is pressed onto the skin material and high frequency is applied. By fusing the mirror case and the skin material together, and then pressing a cutting blade provided on the inner periphery of the high-frequency welding electrode against the skin material, the skin material can be separated along the inner shape of the mirror case. It is characterized by

以上の方法によれば、高周波ウエルダ時にミラ

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。 According to the above method, the mirror is integrally fused to the mirror case during high-frequency welding, and then the cutting blade is used to cut off the scraps of the skin material that have formed on the inner periphery of the adhesion so that they can be separated. So,
After cutting off the scraps, no gap is generated in the cut portion, and the product quality is improved.

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。 Furthermore, in the present invention, the mirror can be fixed within the mirror case at the same time as it is bonded to the surface of the mirror case, so the number of man-hours can be saved.

≪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

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。 Therefore, after the electrode 26 comes into contact with the lower mold 25,
When the template 22 is further lowered, the electrode 26 is moved to the elastic body 2.
2b is held in that position, and the cutting blade 27 is relatively lowered.

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。 Next, a welding method using the high frequency welding apparatus having the above configuration will be explained.

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。 First, as shown in FIG. 1, a mirror 30 with a mirror case 25 attached to its periphery is placed on the lower mold 25. Then, its upper surface is covered with a skin material 34.

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。 Note that a high frequency welding aid 36 is interposed between the peripheral edge of the mirror and the adhesive surface of the mirror case 32.

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。 High frequency welding aids include EVA type, urethane type,
When forming the welding aid 36 on the outer periphery of the mirror using a heat-resistant adhesive such as NBR, it is applied by silk printing or the like.

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。 Further, a welding aid 36 is applied to the back surface of the mirror case 32 in the same manner.

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。 Note that the welding aid 36 may be applied to either the mirror 30 or the mirror case 32.

以上のセツテイング操作終了後に、上側型板２

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。 After completing the above setting operations, the upper template 2
2 is lowered and the high frequency welding electrode 26 is pressed against the surface of the skin material 34 as shown in FIG.

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。 In this state, the mirror 30 and the mirror case 32 are completely bonded together by melting the high frequency welding aid 36, and the mirror case 32 and the skin material 34 are fused together by their own heating.

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。 Next, stop oscillation while maintaining this state,
Further, by lowering the template 22, the cutting blade 27 is lowered as shown in FIG.

以上の動作終了後に型板２２を引き上げ、完成

４が一体となつたものを得られる。 After the above operations are completed, the template 22 is lifted up, the finished product is taken out from above the lower mold 25, and the scraps 34' of the skin material 34 are peeled off starting at the thinned portion 40 by the cutting blade 27. As shown in FIG. 3c, a mirror 30, a mirror case 32 and a skin material 3
You can get a combination of 4.

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。 The cut portion of the obtained product is in close contact with the mirror 30 due to the high frequency welding aid 36, resulting in a clear border.

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。 Then, a sun visor having a cross-sectional shape as shown in the prior art shown in FIG. 4 is assembled using the material thus constructed.

なお、前記実施例では高周波接着用の接着媒体
