Description
プレートの溝にねじのねじ切り頭部を圧入することによるロックは、他のシステムでも得られることに留意されたい。溝での物質の変形に必要な力は大きい。さらに、金属粒子が剥がれる危険性を除外できない。
なお、本発明は、添付図面に関する実施形態の以下の説明を読めば、いっそう理解されるであろう。
図1に示した本発明の第一の実施形態では、リング3が、部品1の孔2の内部で移動自在に取り付けられる。そのため、リング3は、スリット入りの、外周面がほぼ球面の環状としてあり、部品1の孔2に係合するように、ほぼ球面の中ぐり孔の内部に収容される。こうした球面を有する形状により、孔の内部でねじの取付け方向を自在に選択でき、リングが、回り継手と同等物を構成する。
ねじを切ったこのロッドの頭部は、ねじ止めされる自由端、またはこの自由端の近くに突出部8を備えており、突出部は、場合によっては、ねじ止め終了位置でリング3の正面と当接し、部品1が支持体Sに接近できるようにしている。特に図1に前記突出部を示した。この装置の長所の一つは、ねじ付きロッドが部品と支持体との間の境界面の種類および品質とは無関係にロックされるにもかかわらず、部品と支持体との距離をこのように任意に変えられることにある。
Claims (10)
- 少なくとも一つの固定部材(4)を用いて、大きな骨等の支持体(S)に骨接合プレート等の部品(1)を接合し、前記固定部材を、支持体(S)にねじ止めされるように、前記部品(1)のリング(3)を収容する孔(2)を貫通するねじ付きロッドの形状とした支持体への部品接合装置であって、
リング(3)が収縮するリングであり、リングの非円形の外部輪郭が部品(1)の孔(2)の非円形の内部輪郭と係合することにより、孔(2)にリング(3)を係止固定するとともに、リング(3)を孔(2)内部で回転させると、リング(3)が収縮してねじ付きロッド(4)を固定することを特徴とする支持体への部品接合装置。 - リング(3)に溝が形成されたことを特徴とする請求項1記載の支持体への部品接合装置。
- リング(3)が、部品(1)の孔(2)の内部に、取付け方向を選択可能に取り付けられることを特徴とする請求項1又は2記載の支持体への部品接合装置。
- リング(3)を、溝が形成されたほぼ球面を有する環状とし、かつ、リング(3)を、該リングが部品(1)の孔(2)に係合するほぼ球面を有する中ぐり孔の内部に、収容したことを特徴とする請求項1〜3のいずれか一項に記載の支持体への部品接合装置。
- リング(3)が、正面に溝(6)等の連結要素を備え、リング(3)を回転させる工具と係合するように構成されていることを特徴とする請求項1〜4のいずれか一項に記載の支持体への部品接合装置。
- リング(3)が、部品(1)の孔(2)に予め取り付けられていることを特徴とする請求項1〜5のいずれか一項に記載の支持体への部品接合装置。
- リング(3)が、部品(1)の孔(2)に着脱式に取り付けられることを特徴とする請求項1から5のいずれか一項に記載の支持体への部品接合装置。
- ねじ付きロッド(4)が、ねじ止め端と呼ばれる自由端に、ねじ締め工具が係合するための少なくとも一つの中空の凹部または隆起した凹部(7)を有することを特徴とする請求項1〜7のいずれか一項に記載の支持体への部品接合装置。
- ねじ付きロッド(4)が、ねじ止め端と呼ばれる自由端に突出部(8)を有し、前記突出部が、ねじ止め終了位置でリング(3)の正面と当接し、部品(1)を支持体(S)に接近可能としたことを特徴とする請求項1〜8のいずれか一項に記載の支持体への部品接合装置。
- 部品(1)が、予め取付け方向が選択された孔(2)を有し、前記孔が、部品(1)の孔(2)の内部でリング(3)を保持する内部当接部(9)を有することを特徴とする請求項1又は2記載の支持体への部品接合装置。
