Hidden Door Mechanism: It's Obvious How to Open It

A door disguised as something else. It might be a section within a full wooden bookshelf, an old-fashioned refrigerator, a storage cabinet, or a seemingly continuous wainscoting panel. When closed, it is perfectly flush with its surroundings, with only a three-millimeter gap. The opening action is smooth, the door leaf is thick and heavy, and it opens and closes almost silently. The moment it opens, a completely different space and light behind it can be seen. Avoid: adding obvious handles and markings to the hidden door, making the door gap wide enough to be easily noticed, making the mechanism exaggerated and requiring complex operation, having the space behind the door directly be the bar without a transition.

一道偽裝成別的東西的門。它可能是一整面木質書架中的一段、一台老式冰箱、一道置物櫃、或一面看起來連續的護牆板;關起來時與周圍完全齊平,只有一道三毫米的縫。推開的動作很順,門扇很厚很重,開闔時幾乎沒有聲音。開的那一瞬間可以看到後面完全不同的空間與光。避免:在隱藏門上加設明顯的把手與標示、讓門縫寬到一眼看出、把機制做得誇張需要複雜操作、讓門後直接就是吧台沒有過渡。
