- the arcuate surface portion 151u of the present embodiment is an arcuate surface centered on the rotation center axis of the hook 157. As can be seen from the positional relationship between the elongated hole 201a of the striker contact member 201 and the protrusion 157t of the hook 157 in FIG. 4, the arcuate surface portion 151u contacts the striker contact when the stopper protrusion 201s of the striker contact member 201 contacts. The contact member 201 is held at a position farthest from the pole 161. The arcuate surface portion 151u functions when the hook 157 is in the unlocked position and between the unlocked position and the locked position.
- the flat surface portion 151v is in contact with the stopper protrusion 201s of the striker contact member 201. Then, the striker contact member 201 is held at a position moved in the direction of the pole 161 from the state of the arcuate surface portion 151u. In the flat portion 151v, the hook 157 functions between an intermediate state between the unlock position and the lock position and a state immediately before the lock position.
- the striker contact member A stopper mechanism that restricts the movement in the direction of contact with the striker 153 of 201 is configured.
- the flat portion 151v may restrict movement of the hook 157 rotating in the lock position direction in the direction in which the hook 157 contacts the striker 153 of the striker contact member 201 until the state immediately before the lock position. Alternatively, immediately after the hook 157 rotating in the lock position direction exceeds the intermediate state between the unlock position and the lock position, the restriction on the movement of the striker contact member 201 in the direction of contact with the striker 153 is released. May be.
- the hook 157 urged in the unlocking direction by the urging force of the spring 171 has a protrusion 157g (see FIG. 2) that is a bent protrusion 151g (see FIG. 2) of the base 151. 1 (see FIG. 2), and further rotational movement in the unlocking direction is prohibited.
- the stopper protrusion 201s of the striker contact member 201 is in contact with the stopper surface 151s of the protrusion 151t of the base 151.
- the stopper protrusion 201s contacts the arcuate surface 151u of the stopper surface 151s, and the striker contact member 201 is located at a position farthest from the pole 161.
- the pole 161 is in contact with the first convex portion 157b of the hook 157 at a portion closer to the center of rotation than the concave portion 161b.
- the stopper protrusion 201s of the striker contact member 201 moves from the arc surface 151u of the stopper surface 151s of the protrusion 151t to the flat surface 151v. Therefore, the striker contact member 201 moves linearly in the direction of the pole 161 until the planar wall surface of the groove 201b contacts the striker 153.
- the stopper protrusion 201s of the striker contact member 201 is detached from the stopper surface 151s of the protrusion 151t immediately before the hook 157 reaches the lock position.
- the striker abutting member 201 biased by the spring 171 is sandwiched in cooperation with the wall surface of the groove 157a of the hook 157 with the wall surface of the groove 201b abutting against the striker 153, and the groove 157a of the striker 153 and the hook 157. Eliminate the gap.
- the spring 171 biases the hook 157 toward the unlock position via the striker contact member 201.
- the unlocking operation force only needs to resist the urging force of the spring 173 that urges the pole 161, so that the operation force when unlocking is reduced.
- the spring 171 biases the hook 157 toward the unlock position via the striker contact member 201.
- the base 151 is provided with the protrusion 151t having the stopper surface 151s
- the striker contact member 201 is provided with the stopper protrusion 201s that can contact the stopper surface 151s.
- the contact member 201 may be provided with a protrusion having a stopper surface
- the base 151 may be provided with a protrusion capable of contacting the stopper surface.
- the hook 157 has the concave portion 157d and the pole 161 has the convex portion 161a. Conversely, the hook 157 may have the convex portion and the pole 161 may have the concave portion.
- the stopper surface 151s may be provided on the side of the pole 161 instead of the base 151.
- the striker contact member 201 of the above embodiment is provided with the long hole 201h through which the bush 145 is inserted and the bush 145 is inserted therethrough, but may be formed so as not to interfere with the bush 145.

図9に示すアンロック状態にある場合、ポール9のピン17に、ストライカ当接部材13のカム穴13aのストッパ部13bが当接し、それ以上のストライカ当接部材13のUL方向の回転が禁止されている。
本発明は、上記問題点に鑑みてなされたもので、ロック解除時の操作力が小さく、操作性がよいロック装置を提供することを目的とする。
ベースと、
該ベース上に設けられ、ストライカが進入可能な溝が形成され、前記ストライカが前記溝に進入可能なアンロック位置から前記ストライカの前記溝からの離脱を禁止するロック位置まで回転可能なフックと、
前記ベース上に回転可能に設けられ、前記ロック位置に位置する前記フックに係合することにより前記フックの回転を禁止し、前記フックに係合する方向に付勢されたポールと、
前記フック上に設けられ、前記フックの溝に進入したストライカを前記フックの溝と協働して挟むように当接するストライカ当接部材と、
前記ストライカ当接部材を介して前記フックを前記アンロック位置方向に付勢すると共に、前記ストライカ当接部材を前記ストライカに当接する方向に付勢する付勢部材と、
を具備するロック装置が提供される。
ロック装置は、移動側の部材と固定側の部材のそれぞれに取り付けられる。移動側の部材とは、例えば、車両のフロアに対して回転可能に設けられたシート、ドア、トランクリッド、エンジンフッド等である。固定側の部材とは、例えば車体ボデーである。ロック装置は、移動側の部材と固定側の部材との相対移動を阻止可能な装置である。
ロック装置は、ベース151と、ストライカ153とを有している。ベース151が移動側の部材と固定側の部材のいずれか一方に取り付けられ、ストライカ153が移動側の部材と固定側の部材のいずれか他方に取り付けられている。
ベース151には、ストライカ153が進入可能な溝151aが設けられている。ベース151は、フック157とポール161とを備えている。フック157とポール161は、互いに平行な回転軸回りに回転可能にベース151に設けられている。
ベース151の左側部において、表面には、ベース151側からストライカ当接部材201とフック157とがこの順に積層されている。ストライカ当接部材201には、貫通するトラック形状の長穴201hが設けられている。フック157には、貫通する円形の穴157hが設けられている。ベース151にも貫通する穴151hが形成されている。この穴151hの径と、ストライカ当接部材201の長穴201hの短径とフック157の穴157hの径は、それぞれ略同じ大きさに設定されている。
円筒部145aの外径は、フック157の穴157hの径、ストライカ当接部材201の長穴201hの短径、ベース151の穴151hの径より若干小さく設定されている。円筒部145aは、ベース151の穴151hを挿通し、ベース151の裏面に突出している。円筒部145aの先端部はベース151の裏面でかしめられている。フック157およびストライカ当接部材201はベース151に対して回転可能となっている。
ベース151の表面には、ブッシュ147が設けられている。ブッシュ147は、円筒部147aと、円筒部147aの基部に形成された取付部147bとを有している。円筒部147aは、ポール161の穴161hとベース151の穴151iに挿入されている。取付部147bは、ポール161の穴161hの周縁部に当接する。
円筒部147aの外径は、ポール161の穴161h、ベース151の穴151iの径より若干小さくなるように設定されている。円筒部147aは、ベース151の穴151iを挿通し、ベース151の裏面に突出している。円筒部147aの先端部はベース151の裏面でかしめられている。ポール161はベース151に対して回転可能となっている。
図3に示すようにフック157の凹部157dには、フック157の回転軸と平行で、フック157の回転方向(図3において矢印UL方向、反矢印UL方向)と交差する第1ストッパ面157sと、第1ストッパ面157sと空間を介して対向する第2ストッパ面157uとが形成されている。第1ストッパ面157sおよび第2ストッパ面157uは平面である。
この長穴201aの長径の方向は、前述した長穴201hの長径の方向と同じに設定されている。よって、ストライカ当接部材201とフック157とは、一体となってブッシュ145を回転中心として回転可能である。ストライカ当接部材201は、フック157に対して長穴201h、長穴201aの長径の方向に沿ってのみ直線移動可能となっている。
ここで、フック157の回転軸であるブッシュ145と、ブッシュ145が嵌合するストライカ当接部材201の長穴201hと、フック157の突部157tと、フックの突部157tが嵌合するストライカ当接部材201の長穴201aとで、ストライカ当接部材201を直線状に案内するガイド機構が構成されている。
フック157とストライカ当接部材201とを重ね合わせた状態において、長穴201hの中心からフック157の溝157aの長手方向の中心までの距離は、長穴201hの中心から長穴201aの中心までの距離より短い。これにより、ストライカ153が溝157aに当接する際に、長穴201hと長穴201aの2つの支持点の間に位置する溝157aにストライカ153が当接し、ストライカ153が確実に支持される。
ストライカ当接部材201には、突部151tのストッパ面(立壁面)151sに当接可能なストッパ突部201sが形成されている。図4に示すように、ベース151に設けられた突部151tのストッパ面151sは、円弧面部151uと、円弧面部151uに連設された平面部151vと、を有している。
(アンロック状態からロック状態にする場合)
図4に示すアンロック状態にある場合、スプリング171の付勢力により、アンロック方向に付勢されたフック157は、その突部157g(図2参照)がベース151の折曲突部151g(図1、図2参照)に当接し、それ以上のアンロック方向の回転移動が禁止されている。この状態では、ストライカ当接部材201のストッパ突部201sはベース151の突部151tのストッパ面151sに当接している。更に詳しくは、ストッパ突部201sはストッパ面151sの円弧面部151uに当接し、ストライカ当接部材201はポール161から一番離れた位置に位置している。一方、スプリング173の付勢力により、ポール161は、その凹部161bより回転中心に近い部分がフック157の第1凸部157bに当接している。
図7に示すロック状態において、ロック解除するには、スプリング173の付勢力に抗して、ポール161を反矢印E方向に回転させる。すると、ポール161はフック157から離れ、フック157の凹部157dと、ポール161の凸部161aとの係合が解除され、フック157はスプリング171の付勢力により、アンロック位置方向に回転し、図6、図5の状態を介して、図4に示すようなストライカ153がフック157の溝157aから離脱できるアンロック状態となる。
(1) スプリング171は、ストライカ当接部材201を介してフック157をアンロック位置方向に付勢している。
(2) スプリング171は、ストライカ当接部材201を介してフック157をアンロック位置方向に付勢している。
(3) ストライカ当接部材201は直線移動して、溝201bの平面状の壁面がストライカ153に当接するので、ストライカ当接部材201のストライカ153への食い込みがない。よって、ロック解除操作力は、ポール161を付勢しているスプリング173の付勢力に抗するものであればよいので、ロック解除時の操作力が小さくなる。
(1) 上記実施形態では、ベース151にストッパ面151sを有する突部151tを設け、ストライカ当接部材201にストッパ面151sに当接可能なストッパ突部201sを設けたが、逆に、ストライカ当接部材201にストッパ面を有する突部を設け、ベース151にストッパ面に当接可能な突部を設けてもよい。
(3) ストッパ面151sはベース151でなく、ポール161の側部に設けてもよい。
