handrail
A handrail is a rail that is designed to be grasped by the hand so as to provide stability or support.〔(【引用サイトリンク】title=Dictionary.com )〕 Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls. Other applications include bathroom handrails—which help to prevent falls on slippery, wet floors—and barres, which serve as training aids for ballet dancers. Handrails are typically supported by posts or mounted directly to walls.
==History of the handrail==
The first handrail was recognized in history when French archaeologist Pierre St. Jamaine uncovered an Assyrian ruin in southern Iraq in the city-state Nippur.
