【考案の詳細な説明】
この考案は、自動車用樹脂製バンパの改良に関
するものである。[Detailed Description of the Invention] This invention relates to an improvement of a resin bumper for automobiles.
近年、自動車の軽量化という観点から、車体部
品の合成樹脂化が試みられており、バンパについ
ては既に実用化されている。 In recent years, from the perspective of reducing the weight of automobiles, attempts have been made to use synthetic resin for car body parts, and bumpers have already been put into practical use.
しかしながら、樹脂製バンパは、従来の鉄製バ
ンパに比較して強度上の問題特に耐衝撃性におい
て劣る問題があり、縦リブや横リブでバンパフエ

れている（実開昭52−132539号公報）。 However, compared to conventional iron bumpers, resin bumpers have problems with strength and are inferior in impact resistance, so the bumper face is reinforced with vertical and horizontal ribs, or a highly rigid impact dispersion plate is installed inside the bumper face. A shock-absorbing bumper has been proposed in which a shock-absorbing bumper is embedded.
ところで、上記のようにバンパフエースを縦リ
ブと横リブで補強する構造では、樹脂製バンパの
成形時、凝固過程で温度分布の不均一に起因する
ひきつれ所謂リブひけを生ずる難点があつた。か
かるリブひけは、いうまでもなくバンパの外観を
損ね、特に、バンパにボデー色塗装を施す場合に
は、このリブひけが強調されるといつた問題があ
つた。 However, in the structure in which the bumper face is reinforced with vertical ribs and horizontal ribs as described above, there is a problem in that when a resin bumper is molded, rib sinkage occurs due to uneven temperature distribution during the solidification process. Needless to say, such rib sinkage impairs the appearance of the bumper, and especially when the bumper is painted in a body color, there is a problem in that the rib sinkage is accentuated.
この考案は、かかる問題を解消すべくなされた
ものであつて、リブひけを確実に防止することが
でき、しかも軽量性を損なうことがない自動車用
樹脂製バンパを提供することを目的としている。 This invention was made in order to solve this problem, and the purpose is to provide a resin bumper for an automobile that can reliably prevent rib sinkage and does not impair its light weight.
このため、この考案においては、縦リブの前縁
とバンパフエースの断面との間と縦リブの上縁と
バンパフエースの上面との間に樹脂製インサート
部材を介在させた状態でバンパを一体成形し、こ
の樹脂製インサート部材によつて、上記の会合部
におけるひきつれ即ちリブひけを防止するように
したことを基本的な特徴としている。 Therefore, in this invention, the bumper is integrally molded with a resin insert member interposed between the front edge of the vertical rib and the cross section of the bumper ace, and between the upper edge of the vertical rib and the upper surface of the bumper ace. The basic feature is that this resin insert member prevents twitching, that is, rib sinking, at the above-mentioned meeting portion.
以下、図示の実施例に基づいてこの考案をより
具体的に説明する。 This invention will be explained in more detail below based on the illustrated embodiments.
第１図および第２図に示すように、この考案に

からなる。 As shown in FIGS. 1 and 2, a resin bumper 1 for an automobile according to the present invention is an injection molded product using synthetic resin, and has a vertical surface 2 and stepped curved portions above and below the vertical surface 2. A bumper face 5 having a substantially U-shaped cross section and having an upper surface 3 and a lower surface 4 continuous through 2a and 2b, vertical ribs 6, ..., 6 and upper and lower horizontal ribs 7 that reinforce the back surface (inner wall surface) side of the bumper face 5. , 7', and vertical and upper surface side resin insert members 8 and 9 interposed between the vertical surface 2 and upper surface 3 of the bumper face 4 and the meeting portions of the vertical ribs 6.
なお、上記樹脂バンパ１は、第１図に示すよう

図つている。 As shown in FIG. 3, the vertical side and top side resin insert members 8, 9 are shaped in advance to follow the vertical side 2 and the back side of the top side 3 of the bumper face 4 prior to molding the bumper. Portions 8a, 8a, 9a which are molded and connect to the vertical edge 6a on the vertical surface 2 side of the vertical rib 6 and the upper edge 6b on the upper surface side, respectively.
Openings 10, 11 are provided between and 9a to reduce the weight of the insert members 8, 9 and to save material.

防止される。 As described above, if the bumper 1 is injection molded with the insert members 8 and 9 attached to the core mold, the rib sink due to the strain between the bumper face 5 and the vertical ribs 6 that may occur during the solidification process will be avoided. Since the insert members 8 and 9 are interposed in the process, this is reliably prevented.

An insert member (not shown) is provided that integrates the corresponding parts, and the bumper 1 is assembled with each insert member attached to the core mold.
Alternatively, injection molding may be performed.
