使用者が再びシールド５を引き下ろして閉じる際、上述したシールド５を後方へ僅かに変移させると、第１の連杆３及び第２の連杆４が後方へ僅かに移動されて（図１０の矢印が示す）ロックが解除され、上述した弾性係止片２２の周辺空間による弾性延び代（ｅｌａｓｔｉｃ ｍａｒｇｉｎ）により僅かに変移する。すると、上述した弾性係止片２２が上述した円弧溝６３１から外れ、上述した傾斜部６１２が上述した第２の軌道６２に落下し、上述したシールド５を閉じる動作を開始する。これによって、閉じる動作の過程において、上述した第２の軌道６２上で移動するとともに、上述した第２の軌道６２と第１の軌道６１とが重ね合わされる箇所まで変位し、上述した弾性係止片２２が第１の軌道６１の前端位置まで案内されると、閉じた状態に戻る。 When the user pulls down the shield 5 again to close it, if the shield 5 is slightly displaced rearward, the first connecting rod 3 and the second connecting rod 4 are slightly moved rearward (see FIG. 10). (indicated by an arrow) is released and slightly displaced due to the elastic margin due to the peripheral space of the elastic locking piece 22 described above. Then, the elastic locking piece 22 described above is disengaged from the circular arc groove 631 described above, the inclined portion 612 described above falls onto the second track 62 described above, and the operation of closing the shield 5 described above is started. As a result, in the course of the closing operation, it moves on the second track 62 and is displaced to a position where the second track 62 and the first track 61 are superimposed, and is elastically locked as described above. When the strip 22 is guided to the front end position of the first track 61, it returns to the closed state.

ここで、上述したヘルメット本体１の両側には、ピボット座２を介して第１の連杆３及び第２の連杆４が対応枢着され、２つの連杆が連動することによりヘルメット本体１に対するシールド５の角度をスムーズに調整することができ、シールド５を引き起こして開く際、ヘルメットの形状に応じて角度を変化させ、シールド５を密着させた状態でヘルメット本体１に隣り合う。
また、上述した第１の連杆３及び第２の連杆４は、両方とも湾曲状の連杆からなってもよいし、一方が湾曲状の連杆で他方が直線状の連杆（図１１に示すように、２本の連杆は、一方が湾曲状で他方が直線状など任意の組み合わせでもよい）の組み合わせからなってもよいし、２つの連杆間には、角度が調整可能な余裕空間が残されてもよい。 A first connecting rod 3 and a second connecting rod 4 are pivotally mounted on both sides of the helmet body 1 via pivot seats 2. The angle of the shield 5 with respect to the shield 5 can be adjusted smoothly, and when the shield 5 is raised and opened, the angle is changed according to the shape of the helmet, and the shield 5 is brought into close contact with the helmet body 1. - 特許庁

（２）第１の連杆及び第２の連杆は、両方とも湾曲状の連杆からなるか、一方が湾曲状の連杆で他方が直線状の連杆の組み合わせからなってもよく、シールドを引き起こして開くときは、ヘルメットの形状に応じて角度を変化させ、シールドを密着させた状態でヘルメット本体に隣り合わせることにより、ヘルメット本体のシールドが受ける風抵抗が大きくなりすぎるという従来の問題を改善することができる。
（３）シールドを引き起こして開くか引き下ろして閉じる際、連杆上に形成された経路溝に沿って弾性係止片が移動するため、シールドを引き起こして開くか引き下ろして閉じる動作を確実に行い、容易に位置決めさせることができる。
（４）突出ブロック部により弾性係止片を適切に位置拘束し、シールドを引き起こして開く角度を制限することができ、シールドを引き起こして開く動作は、多段式で複数の角度を選択することができる。 As can be seen from the above, the helmet shield pivoting structure of the present invention has the following advantages (1) to (4) as compared with the prior art.
(1) The helmet main body and the shield can be assembled by a simple fitting operation via the pivot seat, and the entire helmet can be discarded because it can be attached and detached when the above-mentioned multiple members are damaged or become obsolete. It is easy to assemble, practical, and cost-saving because only the damaged or old parts can be replaced with new ones.
(2) both the first connecting rod and the second connecting rod may be curved connecting rods, or may be a combination of one curved connecting rod and the other linear connecting rod; When the shield is pulled open, the angle is changed according to the shape of the helmet, and the wind resistance received by the shield of the helmet body becomes too large by changing the angle according to the shape of the helmet and placing the shield in close contact with the helmet body. can be improved.
(3) When the shield is pulled up to open or pulled down to close, the elastic locking piece moves along the path groove formed on the connecting rod, so that the shield can be pulled up to open or pulled down to close without fail, It can be positioned easily.
(4) The protruding block portion appropriately constrains the position of the elastic locking piece and limits the angle of raising and opening the shield. can.
