背景技術
[0002] 自動車、航空機などの乗物に用いられるパーセルトレーなどの室内化粧品あるい は屋内の壁などに用いられる化粧板などの内装部品であって、シートブロー成形に よる内装部品の中間部材として断熱材あるいは吸音材など空気層を有する材料、鋼 管やフレームなどの補強材を配置した榭脂中空成形品は、特開平 10— 80982号公 報に記載されている。また、シート状パリソンをブロー成形して榭脂中空成形品を成 形するとともにブロー成形時に発泡体を内装する榭脂中空成形品は、特開 2000—

発明の開示
発明が解決しょうとする課題
[0003] 特許文献 1およびに記載されている榭脂成形品は、そのブロー成形時に発泡体や 補強材などの中間部材をインサートするものであり、また、特許文献 2に記載されてい る榭脂中空成形品も、予め成形してある発泡体をブロー成形時にインサートし、補強 材を内装する場合には成形後に補強材を挿入する加工を要するものである。
[0004] このため、榭脂中空成形品に内装する中間部材が複数の場合には、金型間にお ける中間部材の配置や位置決めが容易でなぐ成形精度が低下したり、中間部材の 充密状態が得られずガタつきが生じたり、金属製の補強材のように収縮を起こさない 中間部材の場合には榭脂中空成形品の成形収縮による変形が大きくなるなどの問 題点が指摘されている。
[0005] そこで、本発明は、中空部内に中空部内の空間と略同一形状に予め成形された熱 可塑性榭脂からなる発泡体を内装して発泡体を榭脂製パネルの表壁と裏壁の内壁 面に溶着させるとともに、発泡体には補強材を配置させるための収容部を形成してお くことにより、発泡体と補強材のように複数の部材を一度に金型間に配置させることが 可能で成形工程が容易となり、発泡体に補強材を保持させているので、補強材の位 置決めが的確にできて、ガタツキ防止や成形収縮による変形を起こすことがな 、榭 脂製パネルおよびその製造方法を提供することを目的とするものである。
課題を解決するための手段
[0006] 上記目的を達成するための本発明の請求項 1に係る榭脂製パネルは、表壁と裏壁 および表壁と裏壁を繋ぐ周囲壁力 なる中空二重壁構造の榭脂製パネルであって、 榭脂製パネルの周囲壁にはその全周に溶着部を有し、中空部内には中空部内の空 間と略同一形状に予め成形された熱可塑性榭脂からなる発泡体が内装されるととも に、発泡体が榭脂製パネルの表壁と裏壁の内壁面に溶着されており、発泡体には補 強材を配置させるための収容部が形成されていることを特徴とするものである。
[0007] 本発明の請求項 2に係る榭脂製パネルは、請求項 1記載の榭脂製パネルにぉ ヽて 、補強材は長尺状であり、補強材の少なくとも一方の端部と周囲壁との間には発泡体 が介在されて 、ることを特徴とするものである。
[0008] 本発明の請求項 3に係る榭脂製パネルは、請求項 1記載の榭脂製パネルにぉ 、て 、補強材は長尺状であり、補強材の少なくとも一方の端部と周囲壁との間には発泡体 のな 、空洞部を有することを特徴とするものである。
[0009] 本発明の請求項 4に係る榭脂製パネルは、請求項 1、 2または 3記載の榭脂製パネ ルにおいて、発泡体に形成される収容部が発泡体の一方の面から他方の面に向け て窪ませた凹部であることを特徴とするものである。
[0010] 本発明の請求項 5に係る榭脂製パネルは、請求項 1、 2または 3記載の榭脂製パネ ルにおいて、発泡体に形成される収容部が発泡体の一方の面から他方の面に向け て貫通させた揷通孔であることを特徴とするものである。
[0011] 本発明の請求項 6に係る榭脂製パネルの製造方法は、発泡体および補強材を内 装した榭脂製パネルの製造方法において、分割金型間に溶融状態のノ^ソン若しく は榭脂シートを配置し、パリソン若しくは榭脂シートを真空若しくは圧空により金型の キヤビティに押圧成形させ、ついで、補強材を予め成形した発泡体の収容部に保持 させた後、当該発泡体をキヤビティに配置させて型締めを行い、溶融状態のパリソン 若しくは榭脂シートの内面と発泡体の外面を溶着させることを特徴とするのである。 発明の効果
[0012] 本発明によれば、中空部内に中空部内の空間と略同一形状に予め成形された熱 可塑性榭脂からなる発泡体を内装して発泡体を榭脂製パネルの表壁と裏壁の内壁 面に溶着させるとともに、発泡体には補強材を配置させるための収容部を形成してお くことにより、発泡体と補強材のように複数の部材を一度に金型間に配置させることが 可能で成形工程が容易となり、発泡体に補強材を保持させているので、補強材の位 置決めが的確にできて、ガタツキ防止や成形収縮による変形を起こすことがな 、榭 脂製パネルを得ることができる。
発明を実施するための最良の形態
[0013] 図 1は本発明に係る榭脂製パネルの断面図、図 2は同上全体斜視図、図 3は予め 成形された熱可塑性榭脂からなる発泡体に補強材を配置する態様を示す斜視図、 図 4は榭脂製パネル内に補強材を配置した発泡体を内装するブロー成形態様を示 す断面図である。
[0014] 本発明に係る榭脂製パネル 1は、図 1および図 2に示すように、表壁 2と裏壁 3およ び表壁 2と裏壁 3を繋ぐ周囲壁 4からなり、この榭脂製パネル 1は中空二重壁構造で あって 5は中空部である。表壁 2の表面には周囲壁 4にかけて装飾などのための表皮 材 6が貼着されている。
[0015] 榭脂製パネル 1の周囲壁 4にはその全周に溶着部 7を有し、その中空部 5内には発 泡体 8が内装されている。発泡体 8は中空部 5内の空間と略同一形状に予め成形さ れた熱可塑性榭脂からなるものであって、発泡体 8には補強材 9、 9を配置するため の収容部 10、 10が形成されており、収容部 10、 10には補強材 9、 9が配置されてい る。発泡体 8は榭脂製パネル 1の表壁 2と裏壁 3の内壁面に溶着されている。このため 、補強材 9、 9は発泡体 8に確実に保持させて補強材 9、 9の位置決めが的確にでき、 また、中空部 5に内装した発泡体 8および補強材 9、 9のガタツキを防止することがで きる。
[0016] 補強材 9、 9は長尺状であり、丸パイプ、角パイプ、 H鋼型などの形状力 なる金属 製あるいは硬質のプラスチック製である。補強材 9、 9は図 3に示すように、発泡体 8の 収容部 10、 10に嵌め込み状に配置されるが、補強材 9、 9の両方の端部 9a、 9a (少 なくとも一方の端部でよい)と周囲壁 4との間には発泡体 8が介在しており、 8a、 8aは その介在部分である。
[0017] このように、補強材 9、 9の両方の端部 9a、 9aと周囲壁 4との間には発泡体 8を介在 させてあるので、成形収縮分を発泡体 8の介在部分 8a、 8aで吸収させて、榭脂製パ ネル 1と補強材 9、 9の収縮差による変形を起こすことがな ヽ榭脂製パネル 1を得るこ とがでさる。
[0018] なお、補強材 9、 9の少なくとも一方の端部と周囲壁 4との間には発泡体 8の介在し ない空洞部を形成した態様とすることもできる(図示せず)。発泡体 8に形成する上記 収容部 10、 10は、図 3に示すように、発泡体 8の一方の面力 他方の面に向けて窪 ませた凹部であるが、この収容部 10、 10は発泡体 8の一方の面力 他方の面に向け て貫通させた揷通孔であってもよ 、(図示せず)。
[0019] 発泡体 8および補強材 9、 9を内装した榭脂製パネル 1は、図 4に示す態様でブロー 成形される。すなわち、榭脂押出ヘッド 11から押し出される溶融状態のノ リソン 12を 分割金型 13、 13間に配置し、パリソン 12を真空若しくは圧空により金型のキヤビティ 14、 14に押圧して成形し、ついで、予め成形してその収容部 10、 10に補強材 9、 9 を嵌め込んで保持させてある発泡体 8を、一方のキヤビティ 14にシート状パリソン 12 の内面に接するように配置して型締めを行い、互いのキヤビティ 14、 14に配置された ノ リソン 12を分割金型 13、 13のピンチオフ部により榭脂製パネル 1の周囲壁 4の全 周に溶着部 7が形成されるように挟み込むとともに溶融状態のノ^ソン 12の内面と発 泡体 8の外面を溶着させ、補強材 9、 9を配置してある発泡体 8を中空部 5に内装され た榭脂製パネル 1を得るものである。なお、この榭脂製パネル 1は、一対の予備成形 した榭脂シートをブロー成形する態様で成形することもできる(図示せず)。図 4にお いて 15は真空チャンバ一、 16は通気接触面、 17はブローピンである。 [0020] 本発明においてブロー成形とは、筒状のノ リソンまたは複数の榭脂シートを溶融押 し出し若しくは予備成形した榭脂シートを過熱溶融させるとともに、分割金型間に配 置して型締めを行うことにより所望の形状に成形するいわゆるダイレクトブロー成形ま たはシートブロー成形などを 、、エアの吹込みを伴うか否かにつ!、ては問わな!/、も のである。
[0021] 榭脂製パネル 1の表壁 2、裏壁 3および周囲壁 4を構成する熱可塑性榭脂は、プロ 一成形が可能なものであればよぐポリエチレン榭脂、ポリプロピレン榭脂、エチレン —酢酸ビュル共重合体、塩化ビュル榭脂、 ABS榭脂 (アクリロニトリル—スチレン— ブタジエン榭脂)、ポリアミド榭脂、ポリスチレン榭脂、ポリエステル榭脂、ポリカーボネ ート榭脂、変性ポリフエ-レンエーテル等のエンジニアリング 'プラスチックなどが好適 であり、適宜にガラス繊維、カーボンファイバー、炭酸カルシウム、タルク、マイ力など の充填材を添加することができる。
[0022] 発泡体 8は、ポリエチレン、ポリプロピレン、ポリスチレンなどからなり、表壁、裏壁、 周囲壁のパネルを構成する熱可塑性榭脂と同材質であることが望ましい。また、発泡 体には適宜、ガラス繊維、カーボンファイバー、炭酸カルシウム、タルク、マイ力など の充填材を添加することができる。
[0023] 表皮材 6は、天然繊維、再生繊維、半合成繊維、合成繊維およびこれらのブレンド 力もなる繊維を加工して得られる編物、織物、不織布、またはポリ塩ィ匕ビュル (PVC) 、熱可塑性ポリウレタンエラストマ一(TPU)または熱可塑性ポリオレフインエラストマ 一 (TPO)などの熱可塑性エラストマ一(TPE)、ポリエチレンポリオレフイン系榭脂な どの熱可塑性榭脂からなる榭脂シートおよびこれらの積層シートから適宜選択可能 である。
