Description

【０００１】
【発明の属する技術分野】
本発明は、車両用のフードロック装置に関する。
【０００２】
【従来の技術】
従来、車体に開閉可能に支持されたフードを閉止状態に保持する車両用のフードロック装置は、エンジンルーム内のフレームにボルト等の締結部材により固定される基板の裏面、すなわち、フレームに対向する面に、フードに固着されたストライカがフードの閉止時に係合するラッチと、フードが閉止した際、ラッチに係合してフードを閉止状態に拘束するロッキングプレートとを枢着して構成されている。
【０００３】
【発明が解決しようとする課題】
しかし、上述のフードロック装置は、基板をフレームに固定した状態で、基板の裏面側とフレームとの間に隙間が形成されるため、基板の上方から隙間内に針金等を挿入するといった不正手段により、ロッキングプレートの操作部が移動され、ロック解除させられて、フードが開けられてしまうおそれがある。
【０００４】
本発明は、従来の技術が有する上記のような問題点に鑑み、簡単な構成で不正行為によるロック解除を確実に防止しうるようにした車両用フードロック装置を提供することを目的としている。
【０００５】
【課題を解決するための手段】
本発明によると、上記課題は、次のようにして解決される。
(１)車体の取付面に締結部材により固定される取付片を有する基板の前記取付面に対向する面に、前記車体に開閉自在に支持されたフードに固着されたストライカに係脱可能なラッチと、該ラッチに係合可能で、前記フードを閉止状態に拘束するロッキングプレートとを枢着し、該ロッキングプレートの下部に、運転席に配置されたオープナハンドルに連結部材を介して連結される操作部を有する車両用フードロック装置において、少なくとも前記ロッキングプレートの操作部より上方の位置で、前記基板と車体の取付面との間の隙間を覆う水平部を有する保護カバーを、前記基板に固定する。
【０００６】
(２)保護カバーの水平部における車体の取付面に近接する端部に、車体の取付面に沿って上方に延出する垂直部を設ける。
【０００７】
(３)保護カバーが、基板と共に締結部材により車体に共締めされる取付片を有するものとする。
(４)保護カバーが、基板に係合可能な仮止め用の爪部を有するものとする。
【０００８】
【発明の実施の形態】
以下、本発明の一実施形態を添付図面を参照して説明する。
フードロック装置は、締結部材であるボルト(2)により車両のエンジンルーム内のフレーム(3)の前面（図１の手前斜め左下方が車両の前方である）に固定される左右１対の取付片(1a)を有するとともに、ほぼ中央下部に穿設した取付孔(1b)に挿通したボルト(4)により、エンジンルーム内のセンタースティ(5)に固定される基板(1)を有している。
【０００９】
基板(1)におけるフレーム(3)の前面に対向する後面には、フード（図示略）に固着されて、フードの閉止時に、基板(1)の中央上線より切設された溝(1c)に進入してくるストライカ(6)と噛合して回動するラッチ(7)と、フードの閉止時にラッチ(7)に係合可能で、下部に、運転席に配置されたオープナハンドル(図示略)に伝達部材であるワイヤを介して連結される操作部(8a)を有するロッキングプレート(8)とが、それぞれ軸(9)(10)をもって枢着されている。(11)は、基板(1)の前面に、軸(13)をもって枢着され、かつ一側部に操作部(11a)を有するセカンダリーラッチである。
【００１０】
(12)は、基板(1)の後面に固定される側面視ほぼＬ字形に折曲された金属製薄板よりなる保護カバーで、基板(1)の後面において、ロッキングプレート(8)の操作部(8a)より上方の位置で水平方向に延出する水平部(12a)と、フレーム(３)の前面に近接または当接する水平部(12a)の後端から上方に延出する垂直部(12b)と、垂直部(12b)の左右の端部に設けられ、基板(1)の取付片(１a)の前面に重合する左右１対の取付片(12c)と、図２において左側の取付片(12c)の下端から下方に延出する折り曲げ可能な舌片状の爪部(12d)とを有している。
【００１１】
保護カバー(12)は、水平部(12a)及び垂直部(12b)を基板(1)の後面側に配置し、かつ左右の取付片(12c)を基板(1)の左右の取付片(1a)の前面にそれぞれ重合させた状態で、爪部(12d)を内方に折り曲げて基板(1)の外縁に係合させることにより、基板(1)に仮止めさせることができる。
【００１２】
保護カバー(12)を基板(1)に仮止めした状態で、基板(1)及び保護カバー(12)の各取付片(1a)(12c)の取付孔(1d)(12e)にボルト(2)を挿入し、そのボルト(2)により、各取付片(1a)(12c)をフレーム(3)に共締めすることにより、基板(1)及び保護カバー(12)は、フレーム(3)に固定される。基板(1)をフレーム(3)に固定した状態においては、保護カバー(12)は、基板(1)の後面とフレーム(3)の前面との間の隙間(c)を水平部(12a)により覆い、基板(１)の上方からの不正手段による進入を阻止して、不正行為によるフードロック装置のロック解除を防止することができる。また、垂直部(12b)は、フレーム(3)に沿って上方に延出しているので、フードロック装置をフレーム(3)及びセンタースティ(5)に固定する際、その垂直部(12b)がフレーム(3)の前面に当接したり摺接したりしてもフレーム(3)の塗装面を傷つけることがない。
【００１３】
【発明の効果】
本発明によれば、次のような効果を奏することができる。
(ａ)請求項１記載の発明によると、簡単な構成を付加するだけで、不正行為により、ロッキングプレートの操作が移動させられて、フードロック装置がロック解除されることを確実に防止することができる。
【００１４】
(ｂ)請求項２記載の発明によると、フードロック装置をフレームに取り付ける際に、垂直部がフレームの前面に面接触するので、フレームの塗装面を傷付けることがない。
【００１５】
(ｃ)請求項３記載の発明によると、保護カバーを、基板とともに締結部材によりフレームに強固に共締めすることができるので、組付け作業性がよく、また部品点数の削減を図ることができるとともに、基板の剛性を向上させることができ、ロック強度を向上させることができる。
【００１６】
(ｄ)請求項４記載の発明によると、保護カバーを基板に仮止めしておくことができるので、保護カバーと基板とのフレームへの共締めを簡単に行うことができる。
