【考案の詳細な説明】
本考案は地下鉄等の集電用第３軌条の保護カバ
ーに関する。[Detailed Description of the Invention] The present invention relates to a protective cover for a third current collection rail in a subway or the like.
地下鉄車輌の電源は一般に走行レールに沿つて
配置されたレール状の第３軌条より集電子を介し

れている。駅舎区間は同様に保護板４を取付けて
いる。さらに軌条と少しはなれた場所に車両運行
に必要な通信用ケーブルがトラフに収納されて付
設されているが、中でも誘導無線用の誘導線は通
話性能を向上するために軌条の近傍に直線に架設
されることが望ましくその検討がすゝめられてい
る。 Power for a subway vehicle is generally sent to the motor via a current collector from a third rail-shaped rail arranged along the traveling rail. In other words, the current third
As shown in Fig. 1, the rail is centered around a current collector rail 5, and metal brackets 1 are installed to protect parts that are likely to come into contact with the rail for prevention of electric shock and safety measures.
A top plate 2 and a side plate 3 made of pine wood are fixed to the top plate 2 and the side plate 3 made of pine wood. A protection plate 4 is similarly installed in the station building section. Furthermore, communication cables necessary for vehicle operation are housed in troughs and installed at a location slightly away from the rails, but the guide wires for the guided radio are installed in a straight line near the rails to improve communication performance. It would be desirable to do so, and consideration is underway.
本考案はかゝる状況に鑑みなされたものであつ
て、上記誘導線を収納するための機構を設けたプ
ラスチツク製保護カバーに関する。 The present invention has been devised in view of the above situation, and relates to a plastic protective cover provided with a mechanism for housing the guide wire.

（図示せず）の曲りを防止するとともに容易に逸
脱するのを防止する。 The present invention will be explained below based on drawings showing embodiments. In Fig. 2, 7 is a protective cover made of fiber-reinforced plastic made by reinforcing thermosetting resin such as unsaturated polyester with fibers such as glass fiber. It has an inverted L-shape, and dovetail-shaped grooves 8 are formed in the longitudinal direction on the upper surface of the eave portion, as shown in FIG. The cross section of the groove 8 widens toward the back from the opening to prevent a guide wire (not shown) inserted through the opening from being bent and from easily coming off.
保護カバーはポリオレフイン系樹脂のような熱
可塑性樹脂を押出成形したものであつてもよいが
熱硬化性樹脂を含浸したガラス繊維ストランドを
引抜成形したものが好ましい。 The protective cover may be made by extrusion molding a thermoplastic resin such as a polyolefin resin, but it is preferably made by pultrusion molding a glass fiber strand impregnated with a thermosetting resin.
本考案による保護カバーは上述のごとく構成し
たので誘導線の布設が容易にでき、誘導線の逸脱
を防止するための押え具も不要なため布設、保守
作業性にすぐれており、その工業的価値は大であ
る。 Since the protective cover according to the present invention is constructed as described above, it is easy to install the guide wire, and there is no need for a holding device to prevent the guide wire from deviating, so it has excellent ease of installation and maintenance, and its industrial value. is large.
