Patent number: 8893439Abstract: A building is provided with a shutter, a stairway, and a handrail. The handrail has a connection member and a connection apparatus. The shutter opens and closes in a horizontal direction. A gap through which the shutter can pass is formed in the stairway. The handrail is provided at the stairway, and includes a handrail main body and a movable member. A gap through which the shutter can pass is formed in the handrail main body, and the movable member closes the gap in the handrail main body. The connection member connects one end portion of the movable member with the handrail main body such that the movable body is turnable relative to the handrail main body. The connection apparatus releasably connects another end portion of the movable member with the handle main body.Type: GrantFiled: February 28, 2013Date of Patent: November 25, 2014Assignee: Takenaka CorporationInventors: Hideki Fujiwara, Osamu Nakagome
