Description

この発明は、プラットホームの前端縁に設けられるプラットホーム用可動柵装置に関するものである。   The present invention relates to a platform movable fence device provided at a front end edge of a platform.

従来技術によるプラットホーム用可動柵装置の扉支持構造の典型的な例では、開閉する扉の支持は、直動ガイドにより行われている(例えば、特許文献1参照)。
このような直動ガイドは、一般にレール部とスライドブロックから構成されるが、それぞれを取付ける部材には、高精度な取付面を必要とし、これらの精度が悪いと動きが重くなったり、寿命の信頼性が低下する要因になった。
さらに、取付面の精度が良好な場合でも、負荷による全体フレームの変形や歪により同様の現象が発生する。特許文献1に示された装置も、こうした精度や歪による直動ガイドへの影響を最小にするための方式である。
そして、直動ガイドは、外部環境からの塵埃や異物に非常にデリケートであり、こうしたものがスライドブロック内部に侵入した場合、早期に寿命に至る可能性があるため、スライドブロックには、シール構造をとり異物の侵入を防止する必要があった。
In a typical example of a door support structure for a movable platform device for a platform according to the prior art, a door that opens and closes is supported by a linear guide (for example, see Patent Document 1).
Such a linear guide is generally composed of a rail part and a slide block. However, a member to be attached to each requires a high-precision mounting surface. It became a factor that decreased reliability.
Further, even when the accuracy of the mounting surface is good, the same phenomenon occurs due to deformation and distortion of the entire frame due to the load. The apparatus disclosed in Patent Document 1 is also a system for minimizing the influence on the linear motion guide due to such accuracy and distortion.
The linear motion guide is very sensitive to dust and foreign substances from the external environment. If such a material enters the slide block, it may reach the end of its life, so the slide block has a seal structure. It was necessary to prevent the entry of foreign matter.
