Description
【0004】
そこで、鉄板に替えてシャッター式のガード装置を取り付けることにより上記欠点を解消することができるが、巻取収納部を運転室の屋根部で天窓の後方に配置した場合は、前方上方の視野が損なわれることは無いが、シャッターの全長が長くなるので、シャッター巻取り時の体積が大きくなる。
そのため巻取収納部は容量が大きく大型で頑強な構造が必要とされ、またシャッター自体も重いものとなる。[0004]
Then, the above-mentioned fault can be eliminated by replacing the steel plate with a shutter type guard device, but when the winding storage part is disposed behind the skylight at the roof of the driver's cab, the field of view above front is There is no loss, but the overall length of the shutter increases, so the volume at the time of shutter winding increases .
Therefore, the take-up storage unit needs a large capacity, a large and robust structure, and the shutter itself is heavy.

上記構成では、天窓対応部16にスラット相互の掛止めによる可撓構造を用いたが、それに替えて可撓性を有する線材や板材、布(シート)などの可撓性部材19を用いてもよい(図4参照)。
即ち、左右両端で長手方向に延びて、前記ガイドレール7に嵌合する一対の板材や線材の可撓性部材19をシャッター部15に連結し、該左右一対の板材や線材の間を横に延びる横架材(これも板材や線材でよい)で連結する構造でもよい。
この場合も、横向きの横架材を張設する構成に限らず縦横に連結したメッシュ状にしてもよい。
あるいは、これらに替えて布を用いたシートシャッターであってもよい。[0018]
In the above configuration, a flexible structure by holding the slats to each other is used for the skylight corresponding portion 16, but instead, a flexible member 19 such as a flexible wire, plate, or cloth (sheet) may be used. Good (see Figure 4).
That is, the flexible members 19 of a pair of plate members or wires which extend in the longitudinal direction at both left and right ends and are connected to the
Also in this case, not only the configuration in which the transversely extending cross member is stretched but also a mesh shape connected longitudinally and horizontally may be used.
Alternatively, a sheet shutter using a cloth instead of these may be used.

次に、上記ガード8の引出し・巻取り方式は、手動式または自動式等を問わないが、本実施例では巻取収納部6が天窓10後方となり、オペレータの手が届かないので、自動式により引出し・巻取りが行えるように前記巻取り用の軸芯13を回転駆動させるモータ(油圧式や電動式など)を設けることが好ましい。
そして、運転室3内のスイッチ操作により、上記モータを正逆回転させてガード8を軸芯13から引出しまたは巻取ることができる。[0020]
Next, the method of pulling out and winding the guard 8 may be manual or automatic, but in the present embodiment, the
Then, by the switch operation in the driver's
