従来のかゝるクリックストップ機構は、例えば特開平４−１６３３０６号公報 に開示されているように、先端に固定クリック歯を有する弾性腕の基端を取付基 板に連結し、この弾性腕の弾性力で固定クリック歯と係合する多数の可動クリッ ク歯をシールド板に形成してなるものが知られている。 Such a conventional click stop mechanism, as disclosed in, for example, Japanese Patent Application Laid-Open No. 4-163306, connects a base end of an elastic arm having fixed click teeth to a mounting base plate, and It is known that a shield plate is formed with a large number of movable click teeth that engage with fixed click teeth by force.

上記のような従来機構では、弾性腕が片持ちであるので、シールド板の開き方 向の回動時と、閉じ方向の回動時とでは、可動クリック歯の固定クリック歯に対 する押圧点が歯の一側面から他側面へと移り、したがってその押圧点から弾性腕 の基端までの腕長さが変わるため、弾性腕の撓み抵抗が変化し、これによってシ ールド板の節度感に微妙な変化がもたらされることが、本考案者によって究明さ れた。 In the conventional mechanism as described above, since the elastic arm is cantilevered, the pressing point against the fixed click tooth of the movable click tooth is changed between the rotation of the shield plate in the opening direction and the rotation of the closing direction. Moves from one side of the tooth to the other side, and therefore the arm length from the pressing point to the proximal end of the elastic arm changes, so the flexural resistance of the elastic arm changes, which causes a slight sense of moderation in the shield plate. It was discovered by the present inventor that such changes will be brought about.
【０００４】 本考案は、かゝる事情に鑑みてなされたもので、シールド板の回動方向を問わ ず、常に変わらぬ節度感を得ることができる、シールド板用クリックストップ機 構を提供することを目的とする。The present invention has been made in view of such circumstances, and provides a click stop mechanism for a shield plate, which can always obtain a constant click feeling regardless of the rotating direction of the shield plate. The purpose is to

【００２１】 シールド板４の全開位置は、係止爪３６が前記切欠１７の上端壁即ちストッパ 壁４０に当接することにより規制される。この全開位置がシールド板４の着脱位 置であって、係止爪３４が扇形凹部１１に、係止爪３５が切欠１２に、係止爪３ ６が切欠１７に合致するようになっている。The fully opened position of the shield plate 4 is regulated by the engagement claw 36 contacting the upper end wall of the notch 17, that is, the stopper wall 40. The fully opened position is the detachable position of the shield plate 4, and the locking claw 34 is aligned with the fan-shaped recess 11, the locking claw 35 is aligned with the notch 12, and the locking claw 36 is aligned with the notch 17. .
【００２２】 次にこの実施例の作用について説明する。Next, the operation of this embodiment will be described.
【００２３】 シールド板４を帽体２に取付けるには、図６に示すように、シールド板４の全 開位置でシールド板４の枢軸３３を取付基板７の支筒１０に整合させると、枢軸 ３３の係止爪３４，３５が支筒１０の扇形凹部１１及び切欠１２への進入可能位 置に、また別の係止爪３６が案内突壁１６の切欠１７への進入可能位置にくる。To attach the shield plate 4 to the cap body 2, as shown in FIG. 6, when the pivot 33 of the shield plate 4 is aligned with the support cylinder 10 of the attachment substrate 7 in the fully opened position of the shield plate 4, The locking claws 34 and 35 of 33 come to a position where the fan-shaped recess 11 and the notch 12 of the support cylinder 10 can enter, and another locking claw 36 comes to a position where the guide projection wall 16 can enter the notch 17.
【００２４】 そこで、先ずシールド板４の端部を僅かに握って係止爪３４を仮止め突起１３ の下に潜らせながら支筒１０の扇形凹部１１に進入させ（図１０の状態参照）、 次いでシールド板４の端部を取付基板７に向って強く押圧すると、係止爪３５は 、その斜面３５ａでロックレバー１９の第１ロック爪２３の斜面２３ａを一旦押 し退けながら支筒１０の切欠１２に進入し、残る係止爪３６も、その斜面３６ａ で第２ロック爪２４の斜面２４ａを一旦押し退けて案内突壁１６の切欠１７に進 入する。したがって、ロックレバー１９は第１及び第２ロック爪２３，２４に対 応する切欠１２，１７から一旦退出させるようにアンロック位置ＵL へ押しやら れるが、係止爪３５，３６が切欠１２，１７に進入すると、直ちにロックスプリ ング２８の弾発力をもって当初のロック位置Ｌまで戻り、第１及び第２ロック爪 ２３，２４を係止爪３５，３６にそれぞれ係合させる（図７及び図８参照）。こ の係合状態はロックレバー１９をアンロック位置ＵL まで回動しない限り、解く ことはできない。Therefore, first, the end portion of the shield plate 4 is slightly grasped and the locking claw 34 is made to enter the fan-shaped recess 11 of the support cylinder 10 while submerging under the temporary fixing projection 13 (see the state of FIG. 10). Next, when the end portion of the shield plate 4 is strongly pressed toward the mounting substrate 7, the locking claw 35 pushes the slope 23a of the first lock claw 23 of the lock lever 19 by its slope 35a, and withdraws the support cylinder 10 of the support cylinder 10. The engaging pawl 36 that has entered the notch 12 also pushes the inclined surface 24a of the second lock pawl 24 once by its inclined surface 36a and advances into the notch 17 of the guide projection wall 16. Therefore, the lock lever 19 but is forced to the unlock position U L so as to exit once from the notch 12 and 17 that correspond to the first and second locking claws 23 and 24, locking claws 35 and 36 the notch 12 , 17, the elastic force of the lock spring 28 immediately returns to the initial lock position L, and the first and second lock claws 23, 24 are engaged with the locking claws 35, 36, respectively (see FIG. 7 and FIG. 7). (See FIG. 8). As long as the engagement of this is you do not turn the lock lever 19 to the unlocked position U L, it can not be solved.
【００２５】 このようにロックレバー１９は第１，第２ロック爪２３，２４を有し、これら を切欠１２，１７においてシールド板４の係止爪３５，３６と係合するようにな っているので、１本のロックレバー１９により、枢軸３３からの距離を異にした ２個所でシールド板４に係止することができ、シールド板４の結合強度を高める ことができる。As described above, the lock lever 19 has the first and second lock claws 23 and 24, which are engaged with the locking claws 35 and 36 of the shield plate 4 in the notches 12 and 17, respectively. Since the lock lever 19 is provided, it can be locked to the shield plate 4 at two positions with different distances from the pivot 33, and the coupling strength of the shield plate 4 can be increased.
【００２６】 こうしてシールド板４は帽体２に取付けられ、同時にクリックストップ機構３ ９では、固定クリック歯３２，３２の上部のものと可動クリック歯３７，３７… の最下部のものとが弾性腕３１の弾性力により係合して作動状態に入る。そこで 、シールド板４を枢軸３３周りに下方へ回動すれば、シールド板４の３個の係止 爪３４，３５，３６は取付基板７の３個の案内溝１４，１５，１８に係合位置を 移していくので、これら係止爪３４，３５，３６の取付基板７との結合状態は一 層確実なものとなる。In this way, the shield plate 4 is attached to the cap body 2. At the same time, in the click stop mechanism 39, the upper part of the fixed click teeth 32, 32 and the lowermost part of the movable click teeth 37, 37 ... Are elastic arms. The elastic force of 31 engages and enters the operating state. Then, when the shield plate 4 is rotated downward about the pivot 33, the three locking claws 34, 35, 36 of the shield plate 4 are engaged with the three guide grooves 14, 15, 18 of the mounting substrate 7. Since the positions are moved, the connection state of the locking claws 34, 35, 36 with the mounting substrate 7 becomes one layer more reliable.
【００２７】 一方、クリックストップ機構３９では、シールド板４が所定の単位角度回動す る毎に、弾性腕３１を撓ませながら固定及び可動クリック歯３２，３７の係合位 置を変えて節度感を与えると共に、シールド板４をその回動位置に保持すること ができる。On the other hand, in the click stop mechanism 39, each time the shield plate 4 is rotated by a predetermined unit angle, the elastic arm 31 is bent and the engaging positions of the fixed and movable click teeth 32 and 37 are changed to thereby provide a moderation. In addition to giving a feeling, the shield plate 4 can be held in its rotating position.
【００２８】 この場合、特に、中央部に固定クリック歯３２，３２を持つ弾性腕３１は、両 端を取付基板７に連結していて両持ちになっているので、シールド板４の上方又 は下方へと回動方向を変えたとき、可動クリック歯３７の固定クリック歯３２に 対する押圧点が歯の一側面から他側面に移っても、その押圧点から弾性腕３１の 両端までの総合腕長さに変化は起こらず、したがって弾性腕３１の撓み抵抗も変 動しないから、常に一定した節度感を得ることができる。In this case, in particular, since the elastic arm 31 having the fixed click teeth 32, 32 in the central portion has both ends connected to the mounting substrate 7 and is both-sided, the elastic arm 31 can be positioned above or above the shield plate 4. When the rotation direction is changed downward, even if the pressing point of the movable click tooth 37 against the fixed click tooth 32 moves from one side surface of the tooth to the other side surface, the total arm from the pressing point to both ends of the elastic arm 31. Since the length does not change and therefore the bending resistance of the elastic arm 31 does not change, it is possible to always obtain a constant detent.
【００２９】 次にシールド板４を帽体２から取外すには、図９に示すように、シールド板４ を再び全開位置まで回動してから、ノブ２５に指を掛けてロックレバー１９をロ ックスプリング２８の力に抗してアンロック位置ＵL へ回動することにより、第 １，第２ロック爪２３，２４を対応する係止爪３５，３６から離脱させる。次い で、そのまゝの状態でシールド板４の端部下縁に指を掛けて図１０の矢印に従い 、外側方へ引張れば、シールド板４の全ての係止爪３４，３５，３６を扇形凹部 １１及び切欠１２，１７から離脱させることができる。Next, in order to remove the shield plate 4 from the cap body 2, as shown in FIG. 9, the shield plate 4 is rotated again to the fully open position, and then the finger is put on the knob 25 to lock the lock lever 19. The first and second locking claws 23 and 24 are disengaged from the corresponding locking claws 35 and 36 by rotating to the unlocked position U L against the force of the lock spring 28. Then, in that state, put your finger on the lower edge of the end of the shield plate 4 and pull it outwards according to the arrow in FIG. 10, so that all the locking claws 34, 35, 36 of the shield plate 4 are pulled out. It can be detached from the fan-shaped recess 11 and the notches 12 and 17.
【００３０】 上記実施例においては、本考案の要旨を逸脱することなく種々の設計変更が可 能である。例えば、支筒１０及び枢軸３３の結合にねじを用いてもよい。また本 考案は、ジェット片等、他形式のヘルメットにも適用可能である。In the above embodiment, various design changes can be made without departing from the gist of the present invention. For example, a screw may be used to connect the support cylinder 10 and the pivot 33. Further, the present invention can be applied to other types of helmets such as jet pieces.
【００３１】[0031]
以上のように本考案によれば、取付基板に両端を結合した弾性腕の中央部一側 に固定クリック歯を設ける一方、シールド板にその回動軸に中心をもつよう円弧 状に形成した突壁に、弾性腕の弾性力で固定クリック歯と係合し、且つシールド 板の回動に伴い固定クリック歯との係合位置を変える多数の可動クリック歯を設 けたので、シールド板の回動方向の変化に伴い可動クリック歯の固定クリック歯 への押圧点が変化しても、両持ちの弾性腕全体の撓み条件に変化は来たさず、し たがって弾性腕の撓み抵抗は常に一定で、安定した節度感を得ることができる。 As described above, according to the present invention, the fixed click tooth is provided on one side of the central portion of the elastic arm whose both ends are connected to the mounting substrate, while the protrusion formed in the arc shape so that the shield plate is centered on its rotation axis. Since a large number of movable click teeth that engage with the fixed click teeth by the elastic force of the elastic arms and change the position of engagement with the fixed click teeth as the shield plate rotates, the shield plate rotates. Even if the pressing point of the movable click tooth against the fixed click tooth changes with the change of direction, the bending condition of the entire elastic arm of both ends does not change, therefore the bending resistance of the elastic arm is always constant.
