To provide a handrail capable of preventing a central support mechanism from bending downward due to its own weight, etc., capable of withstanding a load caused by a strong wind, etc., and capable of absorbing vibration caused by an earthquake.SOLUTION: The extendable handrail includes an extendable handrail main body 5 having one end rotatably provided in one frame in the front-rear direction and the other end rotatably provided in the other frame in the front-rear direction to close joints, a plurality of support arm members 6 which is rotatable in the front-rear direction between one frame and the other frame and extends in the right-left direction, provided so as to support the extendable handrail main body, and a central maintenance mechanism 7 provided between one frame and the other frame to always position the approximate center of the extendable handrail main body at the approximate center of the joint. When one frame and the other frame sway due to an earthquake and the width of the joint changes, the width of overlap between one end handrail 8 and the other end handrail 9 and a middle handrail 10 changes to absorb the swaying motion.SELECTED DRAWING: Figure 1
【課題】自重等により中央維持機構が下方にたわむことを防止できるとともに、強風等による荷重にもたえることができ、地震による揺れ動きを吸収することができる手摺を提供すること。【解決手段】一方の躯体に一端部が前後方向に回転可能に設けられ、他端部が他方の躯体に前後方向に回転可能に設けられ、目地部を塞ぐ伸縮手摺本体5と、一方の躯体と他方の躯体間に前後方向に回転可能で、かつ、伸縮手摺本体を支持するように設けられ、左右方向に伸縮する複数個の支持アーム部材6と、一方の躯体と他方の躯体間に設けられ、伸縮手摺本体の略中央部を目地部の略中央部に常時位置させる中央維持機構7とで構成され、地震によって一方の躯体と他方の躯体が揺れ動き、目地部の幅が変動した場合には、一方の端部手摺8及び他方の端部手摺9と中間手摺10との重なり合い幅が変動し揺れ動きを吸収する伸縮手摺。【選択図】図1
