の表皮材２２を巻き付けた後、この表皮材２２の重合部
２３を縫い合わせ又は熱溶着で固定して製造している（
例えば、特公昭６３−３４０５９号公報参照）。BACKGROUND OF THE INVENTION In recent years, assist grips have been developed in order to improve the feel when gripping, as shown in FIG. After wrapping the skin material 22, the overlapping part 23 of this skin material 22 is fixed by sewing or heat welding (manufacturing).
For example, see Japanese Patent Publication No. 63-34059).
発明が解決しようとする課題
しかしながら、従来のアシストグリップの製造方法では
、表皮材２２を芯材２０の周囲に巻き付けた際に皺を生

２２は、芯材２０の周囲に巻き付けた後に、その重合部
２３を縫い合わせ又は熱溶着しなければならないため、
作業性が悪く、工数が多くかかるという問題を有してい
る。Problems to be Solved by the Invention However, the conventional assist grip manufacturing method has a problem in that wrinkles occur when the skin material 22 is wrapped around the core material 20, which impairs the appearance. Furthermore, after the skin material 22 is wrapped around the core material 20, the overlapping portion 23 must be sewn or heat welded.
This has the problem of poor workability and a large number of man-hours.
そこで、本発明は上記従来技術の問題点を解消すること
を目的とするものである。Therefore, the present invention aims to solve the problems of the above-mentioned prior art.
課題を解決するための手段
即ち、本発明のアシストグリップの製造方法は、予め筒

入し、次いでこれらを金型内に収容・保持し、その後表
皮体の開口端から表皮体内部に樹脂材料を注入して成形
することを特徴としている。Means for solving the problem, that is, the method for manufacturing an assist grip of the present invention is to insert a core material longer than the skin body into a skin body formed in advance into a cylindrical shape, and then house them in a mold.・It is characterized in that it is held and then molded by injecting a resin material into the inside of the skin from the open end of the skin.
作用
筒状の表皮体の内部に樹脂材料が注入されると、表皮体
は径方向外方へ拡張されるため、表皮体外表面に皺が発
生しない。又、表皮体を予め筒状に形成するため、表皮
体の加工が容易になる。When the resin material is injected into the interior of the working cylindrical skin body, the skin body expands radially outward, so that wrinkles do not occur on the outer surface of the skin body. Furthermore, since the skin body is previously formed into a cylindrical shape, processing of the skin body is facilitated.
実施例 以下本発明の実施例を図面に基づき詳述する。Example Embodiments of the present invention will be described in detail below based on the drawings.
第１図は本発明の一実施例を示す工程図である。FIG. 1 is a process diagram showing an embodiment of the present invention.
即ち、本実施例は、先ず第１図（ａ）に示すように、塩
化ビニル樹脂等のビニルレザーや布等からなる所定寸法

３とする。次いで、第１図（ｂ）に示すように、表皮体
３をまるめ、その重合部４を熱溶着又は縫い合わせ等で
固定して、表皮体３を筒状に形成する。続いて、第１図
（ｃ）に示すように、別途プレス等により所定形状に形
成された金属製の芯材５を筒状の表皮体３の内部に挿入
する。That is, in this embodiment, first, as shown in FIG. 1(a), a sheet-like skin is formed by pasting a sponge material 2 on a skin material 1 of a predetermined size made of vinyl leather such as vinyl chloride resin, cloth, or the like. Let it be body 3. Next, as shown in FIG. 1(b), the skin body 3 is rolled up and the overlapping portions 4 are fixed by heat welding or stitching to form the skin body 3 into a cylindrical shape. Subsequently, as shown in FIG. 1(c), a metal core material 5, which is separately formed into a predetermined shape by pressing or the like, is inserted into the cylindrical skin body 3.
尚、芯材５は、表皮体３よりも長尺であって、その端部
６，６が表皮体３の両開口端から外側に突出するように
なっており、その端部６にそれぞれ位置決め孔７を形成
しである。The core material 5 is longer than the skin body 3, and its ends 6, 6 protrude outward from both open ends of the skin body 3. A hole 7 is formed therein.
次に、第２図に示すように、組み合わせた表皮体３と芯
材５とを金型８の下型９内に収容する。Next, as shown in FIG. 2, the combined skin body 3 and core material 5 are housed in the lower mold 9 of the mold 8.

付勢されている。At this time, the core material 5 can be held at a predetermined position in the mold 8 by engaging its positioning hole 7 with the protrusion 11 of the positioning part 10 of the lower mold 9. FIG. 3 shows a perspective view of the positioning part IO of the lower mold 9, and the tip of the gate block 12 attached to the lower mold 9 so as to be movable up and down may slightly enter the inside of the skin body 3. It has become. Note that the gate block 12 is always urged upward by a spring 13.
次いで、第４図に示すように、下型９に上型１４を重ね

ずれるのを防止している。Next, as shown in FIG. 4, the upper mold 14 is placed on the lower mold 9. As a result, the gate block 12 is pushed down by the upper die 14, and its injection hole 15 communicates with the runner 16 (see FIG. 3) formed in the lower die 9. Then, a molten resin material such as vinyl chloride resin is injected into the skin body 3 through the injection hole 15 of the gate block 12 . still,
A needle 17 is provided inside the mold 8, and the needle 17 prevents the skin body 3 from shifting.
そして、表皮体３の内部に注入した樹脂材料１８が固化
した後、上型１４を開き、アシストグリップ（製品）Ａ
を取り出す（第５図参照）。After the resin material 18 injected into the skin body 3 has solidified, the upper mold 14 is opened and the assist grip (product) A
(See Figure 5).
以上述べたように本実施例は、表皮体３の内部に芯材５
等を挿入する前に、表皮体３の重合部４を縫い合わせ又
は熱溶着等で固定するため、縫い合わせ又は熱溶着の作
業の際に作業の妨げとなるものがなく、その加工作業を
極めて容易に行うことができる。As described above, this embodiment has a core material 5 inside the skin body 3.
Since the overlapping portion 4 of the skin body 3 is fixed by stitching or heat welding before inserting the parts, there is no obstacle to the stitching or heat welding work, making the processing work extremely easy. It can be carried out.
又、予め筒状に形成した表皮体３の内部に樹脂。Further, resin is placed inside the skin body 3 which is previously formed into a cylindrical shape.
を注入する態様であるため、樹脂により表皮体３が径方
向外方へ拡張され、表皮体３に皺を生じることがない。Since this is the mode in which the resin is injected, the skin body 3 is expanded radially outward by the resin, and no wrinkles are caused in the skin body 3.
さらに、アシストグリップＡは、金型８内で成型するた

。加えて、本実施例によれば、表皮体３の重合部４は、
縫い合わせ又は熱溶着のいずれでも容易に加工（固定）
できるため、表皮体３を構成する表皮材ｌの材料が限定
されることがない。Furthermore, since the assist grip A is molded within the mold 8, it can be molded into a desired shape with high accuracy, and decorative patterns and the like can be appropriately formed on its outer surface. In addition, according to this embodiment, the overlapping portion 4 of the skin body 3 is
Easily processed (fixed) by either sewing or heat welding
Therefore, the material of the skin material l constituting the skin body 3 is not limited.
尚、前記実施例は、表皮材Ｉにスポンジ材２を貼着して
表皮体３とする態様を示したが、これに限られるもので
はない。In addition, although the said Example showed the aspect which stuck the sponge material 2 to the skin material I and used as the skin body 3, it is not limited to this.
即ち、表皮材ｌのみで表皮体３を構成し、筒状に形成し
た表皮体３内部に発泡さ仕た樹脂材料を充填することに
より、前記実施例と同様に把持時の感触に優れたアンス
トゲリップＡを製造することができる。That is, by configuring the skin body 3 only with the skin material 1 and filling the inside of the skin body 3 formed into a cylindrical shape with a foamed resin material, it is possible to obtain an grip that has an excellent feel when gripping as in the previous embodiment. Togerip A can be produced.
