Claims (11)
- 回動筒を回動させることにより本体の先端に設けられた孔に挿入される複数の爪を拡縮摺動させ、前記爪により工具を挟持するチャック装置であって、前記本体には環状のラチェット歯が設けられ、また前記回動筒の内方にして前記本体には前記爪と螺合し該回動筒と共に回動する環状の回動体が被嵌され、また前記ラチェット歯の外方には該ラチェット歯と係止する着脱自在な係止バネ体が配設され、この係止バネ体は前記回動体の回動に伴い前記ラチェット歯の周囲を回動する状態で設けられ、この係止バネ体は前記回動体に凹凸嵌合手段により取り付けられ、更に前記ラチェット歯と前記係止バネ体が係止した状態及びこの係止が解除した状態を保持する保持部が設けられ、前記ラチェット歯は、前記本体とは別体にして該本体の周面に形成した凹状固定部に巻き付け固定された帯状で該本体より高硬度の硬質部材に形成されていることを特徴とするチャック装置。
- 請求項1記載のチャック装置において、前記硬質部材は、前記凹状固定部に巻き付けた状態で該凹状固定部をかしめて固定されているものであることを特徴とするチャック装置。
- 請求項1,2いずれか1項に記載のチャック装置において、前記硬質部材は、両端縁が傾斜縁若しくは側縁に対して直交する直交縁に形成されていることを特徴とするチャック装置。
- 請求項1〜3いずれか1項に記載のチャック装置において、前記硬質部材として、鋼若しくはステンレスが採用されていることを特徴とするチャック装置。
- 請求項1〜4いずれか1項に記載のチャック装置において、前記本体は、軽量部材で形成されていることを特徴とするチャック装置。
- 請求項5記載のチャック装置において、前記軽量部材として、非鉄金属若しくはこれらの合金,合成樹脂または繊維強化樹脂が採用されていることを特徴とするチャック装置。
- 請求項1〜6いずれか1項に記載のチャック装置において、前記保持部は、前記係止バネ体を所定の位置に保持することで、前記ラチェット歯と前記係止バネ体が係止した状態及びこの係止が解除した状態を保持するように構成したものであることを特徴とするチャック装置。
- 回動筒を回動させることにより本体に設けられた孔に挿入される複数の爪を拡縮摺動させ、前記爪により工具を挟持するチャック装置であって、前記本体には環状のラチェット歯が設けられ、また前記回動筒の内方にして前記本体には前記爪と螺合し前記回動筒と共に回動する環状の回動体が被嵌され、また前記ラチェット歯の外方には該ラチェット歯と係止する着脱自在な係止バネ体が配設され、この係止バネ体は二つのバネ体から成り、一方の係止バネ体は前記ラチェット歯との係止作用を担うように構成され、また、他方の係止バネ体は前記回動筒の位置を保持することで前記一方の係止バネ体の位置を保持する作用を担うように構成され、これらの係止バネ体は前記回動体の回動に伴い前記ラチェット歯の周囲を回動する状態で設けられ、これらの係止バネ体は前記回動体に凹凸嵌合手段により取り付けられ、さらに前記ラチェット歯と前記一方の係止バネ体が係止した状態及びこの係止が解除した状態を保持する保持部が設けられ、この保持部は前記本体と前記回動筒との間に配されると共に前記他方の係止バネ体と前記回動筒の内面とで構成され、前記本体はアルミ若しくはアルミ合金製等の軽量部材で構成され、前記環状のラチェット歯は、前記本体とは別体にして該本体の周面に形成した凹状固定部に巻き付け固定された帯状で該本体より高硬度の硬質部材に形成されていることを特徴とするチャック装置。
- 請求項8記載のチャック装置において、前記硬質部材は、前記凹状固定部に巻き付けた状態で該凹状固定部をかしめて固定されているものであることを特徴とするチャック装置。
- 請求項8,9いずれか1項に記載のチャック装置において、前記他方の係止バネ体と前記回動筒との凹凸嵌合により、前記ラチェット歯と前記一方の係止バネ体が係止した状態及びこの係止が解除した状態が保持されるように構成されていることを特徴とするチャック装置。
- 請求項1〜10いずれか1項に記載のチャック装置において、前記ラチェット歯に、硬質にして摩擦係数が可及的に小さいコーティングが施されていることを特徴とするチャック装置。
