図４は顔面保護板アセンブリ１０の拡開した状態の背面図、図５は図４のＡ−Ａ線に沿った拡大断面図である。顔面保護板アセンブリ１０では、帽体２の内面に沿った形状の支持板１１の前面側に、顔面保護板１を例えば３個の係合部材１２により昇降自在に取り付けている。顔面保護板１の下縁部には、例えば合成ゴム等から成る保護部材１ａを取り付けている。係合部材１２は雌型係合部材１２ａと雄型係合部材１２ｂとから構成し、支持板１１に顔面保護板１を着脱可能としている。支持板１１の後面側には、係合部材１２の移動を可能とする溝１３ａを有する衝撃防止用のパッキン１３を貼着している。
FIG. 4 is a rear view of the face protection plate assembly 10 in an expanded state, and FIG. 5 is an enlarged cross-sectional view taken along the line AA of FIG. In the face protection plate assembly 10, the face protection plate 1 is attached to the front surface side of the support plate 11 having a shape along the inner surface of the cap body 2 so as to be able to move up and down by, for example, three engaging members 12. A protective member 1a made of, for example, synthetic rubber is attached to the lower edge of the face protection plate 1. The engaging member 12 is composed of a female engaging member 12a and a male engaging member 12b, and the face protection plate 1 can be attached to and detached from the support plate 11. An impact-preventing packing 13 having a groove 13a that allows the engaging member 12 to move is attached to the rear surface side of the support plate 11.
そして、支持板１１の側部１１ｂの端部には、ハンモック４を帽体２に固定するための固定具５ａと係合する取付孔２３を形成している。また、側部１１ｂの中央部１１ａ寄りには、耳紐８を帽体２に固定するための固定具５ｂと係合する取付孔２４を形成している。
Then, at the end of the side portion 11b of the support plate 11, a mounting hole 23 that engages with the fixture 5a for fixing the hammock 4 to the cap body 2 is formed. Further, a mounting hole 24 is formed near the central portion 11a of the side portion 11b to engage with the fixture 5b for fixing the ear strap 8 to the cap body 2.
ここで、図５に示すように顔面保護板１の上部には、係合部材１２を取り付けるための３つの取付孔１ｂを、支持板１１の案内孔２１、２２にそれぞれ対応する位置に形成している。この際に、中央の取付孔１ｂは左右の取付孔１ｂよりも上方に位置させている。
Here, as shown in FIG. 5, three mounting holes 1b for mounting the engaging member 12 are formed on the upper portion of the face protection plate 1 at positions corresponding to the guide holes 21 and 22 of the support plate 11, respectively. ing. At this time, the central mounting hole 1b is positioned above the left and right mounting holes 1b.
顔面保護板アセンブリ１０を組み立てる際には、支持板１１の裏面にパッキン１３を貼着すると共に、支持板１１に固定具２５を組み付ける。次に、支持板１１の前面に顔面保護板１を配置し、係合部材１２の雌型係合部材１２ａを顔面保護板１の前面側からその取付孔１ｂに挿通し、雄型係合部材１２ｂを支持板１１の後面側から雌型係合部材１２ａの押し込む。そして、全ての係合部材１２を顔面保護板１に取り付けた後に、パッキン１３の裏面にシート１４を貼着する。
When assembling the face protection plate assembly 10, the packing 13 is attached to the back surface of the support plate 11, and the fixture 25 is attached to the support plate 11. Next, the face protection plate 1 is arranged on the front surface of the support plate 11, and the female engagement member 12a of the engagement member 12 is inserted into the mounting hole 1b from the front surface side of the face protection plate 1, and the male engagement member The female engaging member 12a is pushed into the 12b from the rear surface side of the support plate 11. Then, after all the engaging members 12 are attached to the face protection plate 1, the sheet 14 is attached to the back surface of the packing 13.
