Claims (18)
- 基部面を形成する外面を有し、任意の形状に熱可塑性材料で成形された、前記基部面から複数のフックが一体に突出する成形物であって、前記成形物および前記複数のフックは射出成形により形成され、前記複数のフックはそれぞれ基部および該基部から突出する頭部または掛止部を備え、かつ前記成形物の前記外面にそれぞれ延在する、前記フックの端縁を形成する中間面によって相互に分離された第1横方向面および第2横方向面によって画定される成形物において、前記第1横方向面および/または第2横方向面と、前記基部面に平行でありかつその基部面から所定の距離hにある平面との交差部によって画定される曲線区分は、それぞれ前記距離hの関数として変化する曲率を有し、h=0(前記基部面および前記平行な面が合致)の場合の前記曲線区分の曲率が、前記複数のフックの前記頭部の位置にほぼ相当する場合の少なくとも1つの曲線区分の曲率より大きく、
それぞれの前記曲線区分は凹状で前記フックの内部に向かって内側へ曲がることにより、前記第1および第2横方向面の曲線区分が対向する窪みを有することを特徴とする成形物。 - 少なくとも前記頭部の、前記2つの横方向面と前記中間面との間の移行部分のレベルでは、前記2つの横方向面の少なくとも一方と前記中間面の間の移行が円滑であること、すなわち山形部分あるいは鋭い端縁が無いことを特徴とする請求項1に記載の成形物。
- 前記2つの横方向面のそれぞれと前記中間面との間に存在する、少なくとも前記頭部の移行部分のレベルでは、前記2つの横方向面の少なくとも1つと前記中間面との間の移行が曲がっていることを特徴とする請求項1または2に記載の成形物。
- 前記中間面は前記2つの第1および第2横方向面に対しほぼ垂直とされることを特徴とする請求項1ないし3のいずれかに記載の成形物。
- 前記フックの前記頭部のレベルの第1断面は第1の曲率半径を有する少なくとも1つの丸みのある隅を有する第1断面を有し、前記フックの前記頭部のレベルの第2断面は第2の曲率半径を有する少なくとも1つの丸みのある隅を有する第2断面を有し、前記第2断面は前記頭部の最末端により近く、かつ前記第2半径は前記第1半径より大きいことを特徴とする請求項1〜4のいずれかに記載の成形物。
- 横の区分(前記基部面に平行な面の断面)の最小厚さ(前記第1と第2横方向面の間の最小距離)は前記フックの前記基部から前記頭部側に増大することを特徴とする請求項1〜5のいずれかに記載の成形物。
- 前記基部面における前記頭部の最小厚さは、前記フックの頭部のレベルにおける前記基部面に平行な面における前記頭部の最小厚さより小さいことを特徴とする請求項1〜5のいずれかに記載の成形物。
- 前記フック頭部の前記断面より小さな、断面方向発達部(前記2つの横方向面および前記中間面に対し横方向の)が前記フックの前記頭部の最末端から突出することを特徴とする請求項1〜7のいずれかに記載の成形物。
- 前記発達部の少なくとも一部分は、断面において山形部分あるいは鋭い端縁の無い移行部分を形成し、同時に前記フックの残部断面は四角形、長方形、菱形もしくは同様の四隅のある四辺形状とされることを特徴とする請求項8に記載の成形物。
- 前記フックの前記発達部と前記頭部の間の移行は肩状部または隅を形成することを特徴とする請求項8または9に記載の成形物。
- 成形される物体を形成するための金型内に配置されて、複数のフックを成形物と一体に形成するための挿入ブロックであって、少なくとも1つの第1プレートであり、フックに対し相補的形状を有しかつ前記プレートの2つの対向する横方向面および前記プレートの上部端縁から出ている複数の切欠をその上部端縁上に有する前記第1プレートと、少なくとも2つの第2プレートであり、前記少なくとも1つの第1プレートを間に挟んで、フックと相補的な前記形状を有した複数の空洞であって、それぞれ前記2つの第2プレートにより形成された横方向壁によって画定されかつ開口を介して前記第1プレートの前記上部端縁から出ている複数の空洞を形成する前記第2プレートと、を備え、前記プレート同士が互いに固定される挿入ブロックにおいて、前記プレートは拡散接合処理によって相互に固定され、前記プレートのうちの少なくとも1つに、前記プレートが相互に当接されるときに、一方では前記複数の空洞それぞれの少なくとも1つの部分と、他方では片方が他方に当接配置された前記プレートにより形成された前記挿入ブロックの外部と、連通する1つの通気路を形成するための少なくとも1つの補助的凹部が形成され、また、前記拡散接合処理の間前記積層されたプレートに作用する圧力が高く前記空洞の壁が変形し、および前記成形される物が請求項1〜10のいずれかに記載の成形物であることを特徴とする挿入ブロック。
- 前記1つの通気路は、前記複数の空洞それぞれの、前記フックの前記頭部を形成するための部分と連通するように形成されることを特徴とする請求項11に記載の挿入ブロック。
- 前記通気路は、小さい断面を有する第1部分および前記小さい断面より大きい断面を有する第2部分によって形成された段付き断面を有し、前記小さい断面は前記フックと相補的な形状を有する前記空洞の頭部と連通することにより空気が熱可塑性材料ではなくこの断面を通ることを可能とするようにされており、かつ前記大きい断面は前記小さい断面から前記大きい断面へと通る前記空気の迅速な排出を可能とし、同空気自体は外部に接することを特徴とする請求項11〜12のいずれかに記載の挿入ブロック。
- 前記通気路の前記断面は拡幅され、空気は通過可能とされるが注入された熱可塑性材料は通れない小さい寸法に始まり前記空気の迅速な排出を可能とする大きい寸法で終わることを特徴とする請求項11〜13のいずれかに記載の挿入ブロック。
- 前記少なくとも1つの補助的凹部は前記少なくとも1つの第1プレートに形成されることを特徴とする請求項11〜14のいずれかに記載の挿入ブロック。
- 前記第2プレートは切欠の無いプレートとされることを特徴とする請求項11〜15のいずれかに記載の挿入ブロック。
- 前記空洞と前記通気路の間の連通用開口の同等の断面の径は5×10−2mmより小さいことを特徴とする請求項11〜16のいずれかに記載の挿入ブロック。
- 前記空洞と前記通気路の間の連通用開口の同等の断面の径は、1×10 −2 mmと4×10 −2 mmの間とされることを特徴とする請求項11〜17のいずれかに記載の挿入ブロック。
