Description
【０００１】[0001]
この考案は自動二輪車、自動車等に乗車する時に着用するフルフェースタイプ のヘルメットに装備されているシールドのロック機構に関する。 The present invention relates to a lock mechanism for a shield mounted on a full-face type helmet worn when riding a motorcycle, an automobile, or the like.
【０００２】[0002]
自動二輪車を運転する時に頭に被るヘルメットとして頭をスッポリ入れるフル フェースタイプのヘルメットがある。このヘルメットは、ヘルメット本体の前面 に前方を視認するための窓孔が開設されており、その窓孔はヘルメット本体の前 面に装備されるクリアー、スモーク、ライトスモーク等のシールドで閉鎖又は開 放状態に切替えられるようになっている。 As a helmet worn on the head when driving a motorcycle, there is a full-face type helmet that puts the head in a slippery manner. This helmet has a window hole on the front of the helmet body for visually recognizing the front.The window hole is closed or opened with a shield such as clear, smoke, light smoke, etc., which is equipped on the front surface of the helmet body. It can be switched to the state.
【０００３】 そして、上記のシールドは自動二輪車の走行時に閉じて窓孔に臨んでいる目に 走行に伴う風圧が当たったり、埃や他物が目に入るのを遮って前方の視認行為が 妨げられないようにし、それによって安全に運転走行が出来るようにしてある。 しかも、全閉されたシールドは走行中に不意に開いたりしないように、シールド の開閉には適度の抵抗が加わる構造にしたり、或いはシールド側に取り付けた突 起を窓孔縁に設けた係合部に係合させて保持するといった手段が講じられている 。[0003] The above-mentioned shield is closed when the motorcycle is running and is exposed to wind pressure accompanying the running of the eyes facing the window hole, and it blocks dust and other objects from entering the eyes, thus hindering the front view action. So that you can drive safely. Moreover, in order to prevent accidental opening of the fully closed shield during traveling, the shield should be opened or closed with appropriate resistance, or a protrusion attached to the shield should be provided on the edge of the window hole. Means have been taken to engage and hold the part.
【０００４】[0004]
ところで、シールドを完全に閉じて走行した場合、ヘルメットの内部と外部と の温度差によって前記シールドの内側面が曇り、前方の視認性が悪くなるといっ た事態が発生するが、そのシールドの曇りはヘルメットの内部に外気を入れるこ とによって解消することが出来る。そして、その外気をヘルメットの内部に入れ る手段としては窓孔を閉鎖しているシールドを上方に回動して窓孔を開口し、そ の開口から外気を入れることが一般的に行われている。しかしながら、閉じられ 、しかもホック釦やロック片の係合によって全閉状態がロックされているシール ドを走行中に片手で外し、且つ所定の開口状態にシールドを回動操作することは 非常に面倒である。 By the way, when running with the shield completely closed, the temperature difference between the inside and outside of the helmet causes the inside surface of the shield to fog and the visibility in front of the shield to deteriorate. It can be resolved by letting outside air into the helmet. As a means for introducing the outside air into the helmet, a shield that closes the window hole is rotated upward to open the window hole, and the outside air is introduced through the opening. There is. However, it is very troublesome to remove the shield that is closed and locked in the fully closed state by the engagement of the hook button and the lock piece with one hand while traveling and rotate the shield to the predetermined open state. Is.
【０００５】 又、仮に走行中にシールドの全閉ロック状態を外してシールドを回動し、外気 の導入が出来たとしても、所定の開口状態にしたシールドはその状態で止めてお くロック機構が無い為、高速での走行中に横を向くと風圧を受けて必要以上にシ ールドが開いてしまう事もあるといった問題点を有する。更に、前述したシール ドの曇りを取る為の外気導入は微小間隙から外気が入り込む程度で充分であるが 、全閉のロック状態を外し、片手操作でシールドをほんの僅か上方に回動すると いった動作は困難で、シールドを適度に開けることは難しく、又、適度に開けて おいても風圧によって必要以上に開いてしまうといったことも起きる。Further, even if the shield can be rotated and the outside air can be introduced while the vehicle is traveling and the outside air can be introduced, the shield in a predetermined opening state can be stopped in that state. However, if you turn to the side while driving at high speed, there is a problem that the shield may open more than necessary due to wind pressure. Furthermore, it is sufficient to introduce the outside air to clear the shield as described above, as long as the outside air enters through the minute gap, but the fully closed locked state is released and the shield is rotated slightly upward by one hand operation. It is difficult to operate, it is difficult to open the shield properly, and even if it is opened properly, it may open more than necessary due to wind pressure.
【０００６】 本考案は上述したような従来の技術の有する問題点に鑑みてなされたもので、 その目的とするところは、シールドの曇りを取る為に該シールドを微小間隙の状 態に回動してその状態でロック出来、しかもその微小間隙への回動を走行中に片 手で容易に行うことが出来るシールドのロック機構を提供することにある。The present invention has been made in view of the problems of the above-described conventional techniques, and an object of the present invention is to rotate the shield in a state of a minute gap in order to clear the shield. Another object of the present invention is to provide a lock mechanism for a shield that can be locked in that state, and that can be easily rotated with one hand with one hand while traveling.
【０００７】[0007]
上記の目的を達成するために本考案が講じた技術的手段は、ヘルメット本体の 前面に窓孔が開設され、その窓孔を閉鎖又は開口状態に切替えるシールドがヘル メット本体の前面に上下回動可能に取付けられたヘルメットにおいて、前記窓孔 における下側孔縁の外側に、シールドを全閉状態で保持する第１係合部と、その 前方又は後方の上方に位置しシールドを僅かに開いた状態で保持する第２係合部 、及びその二つの部位の間を連続的に結ぶ溝を有する係合体を設け、シールド側 には前記第１及び第２係合部と係着する係合突起を有したロックレバーを前後方 向にスライド可能に取付けた構成にある。 The technical means taken by the present invention to achieve the above-mentioned object is that a window hole is opened in the front surface of the helmet body, and a shield for closing or switching the window hole is rotated up and down on the front surface of the helmet body. In a helmet that is mounted so that it is possible to open the shield slightly outside the lower hole edge of the window hole, the first engaging portion that holds the shield in a fully closed state, and the front or rear upper portion thereof. A second engaging portion held in a state, and an engaging body having a groove continuously connecting between the two parts thereof, and an engaging protrusion engaging with the first and second engaging portions on the shield side. The lock lever with is attached so that it can be slid forward and backward.
【０００８】 ヘルメット本体における窓孔の孔縁下側に取付けられる第１係合部、第２係合 部とその間を連絡する溝を夫々独立して形成し、それらを所定の間隔を置いて固 着しても、或いは第１係合部、第２係合部とその間を連絡する溝を合成樹脂材に よって１つの部材に成型加工し、それを孔縁下側の所定箇所に固着するようにし ても良いものである。The first engaging portion and the second engaging portion, which are attached to the lower side of the hole edge of the window in the main body of the helmet, and the groove for connecting the first engaging portion and the second engaging portion are independently formed, and they are fixed at predetermined intervals. Even if it is attached, or the first engaging portion, the second engaging portion and the groove that connects between them are molded into one member with a synthetic resin material and fixed to a predetermined position below the hole edge. It is also good to
【０００９】 更に、シールド側に取付けられるロックレバーのスライド構造は、シールドに スライド範囲を規制する長孔が開設され、その長孔にロックレバーに設けられた 係合突起が嵌合されてスライドするようになっている。又、上記シールドを回動 可能に支持する機構としては、一般的に知られている止めネジによる取付け、或 いは特開昭63−309612号公報に示されている止めネジを使用しない新規な取付け 構造等、今日知られている各種機構を選択使用することが出来る。Further, in the slide structure of the lock lever attached to the shield side, a long hole for restricting the slide range is opened in the shield, and the engaging projection provided on the lock lever is fitted into the long hole and slides. It is like this. Further, as a mechanism for rotatably supporting the shield, a generally known set screw is used, or a new set screw disclosed in JP-A-63-309612 is not used. Various known mechanisms such as a mounting structure can be selectively used.
【００１０】[0010]
上記の手段によれば、シールドに取付けられたロックレバーの裏側に突出され た係合突起を、窓孔の下側孔縁に固着された第１係合部に係着した状態にあって は該シールドの裏面が窓孔の孔縁前面に密着して閉鎖状態が確率されている。そ して、その状態からロックレバーを前方、又は後方の上方にスライドすると、該 ロックレバーの裏側に突出する係合突起は第１係合部の位置より溝に案内されて 前方、又は後方で且つ第１係合部より上方に位置する第２係合部へと案内され、 それに伴い係合突起を支持するシールドは該シールドの回動中心（シールドの左 右両側の取付け部）を支点として上方に回動されると共に、シールドの裏面が窓 孔の孔縁前面から離反する方向に押し出され、窓孔の孔縁前面とシールド裏面と の間に微小間隙が形成されて外気が流入し得る状態となる。 According to the above means, in the state where the engaging protrusion protruding on the back side of the lock lever attached to the shield is attached to the first engaging portion fixed to the lower hole edge of the window hole, The back surface of the shield is in close contact with the front surface of the hole edge of the window, and thus the closed state is established. Then, when the lock lever is slid forward or rearward from that state, the engagement protrusion protruding to the back side of the lock lever is guided by the groove from the position of the first engagement portion to move forward or backward. Further, the shield that is guided to the second engaging portion located above the first engaging portion and that supports the engaging protrusions accordingly has the rotation center of the shield (attachment portions on both left and right sides of the shield) as a fulcrum. As it is rotated upward, the back surface of the shield is pushed away from the front surface of the hole edge of the window hole, and a small gap is formed between the front surface of the hole edge of the window hole and the back surface of the shield, allowing outside air to flow in. It becomes a state.
【００１１】 しかも、その状態では係合突起が第２係合部に係着しているため、ロックレバ ーを意識的に外側に引張って第２係合部との係合を外さない限り風圧等によって シールドが不意に開いたりすることはない。又、シールドを微小間隙の状態から 全閉状態にする時は、該シールドに取付けられたロックレバーを溝に沿ってスラ イドすることで係合突起が第２係合部から第１係合部へと案内されて全閉のロッ ク状態が確立される。Moreover, in that state, since the engaging protrusion is engaged with the second engaging portion, unless the lock lever is intentionally pulled outward to disengage from the second engaging portion, wind pressure or the like is generated. The shield does not open unexpectedly. In addition, when the shield is closed from the minute gap state to the fully closed state, the lock lever attached to the shield is slid along the groove so that the engaging projections move from the second engaging portion to the first engaging portion. Guided to, a fully closed lock state is established.
