HINGED DOOR AND DOOR SWITCHGEAR
To smoothly open and close a hinged door with a foot in a state where a lock of the hinged door is unlocked with the foot.SOLUTION: A door switchgear that opens and closes a hinged door having a doorknob that releases a lock by rotation includes: a doorknob mounting part that is configured to be mountable on the doorknob and has a separated part positioned away from an axis of rotation of the doorknob; a linear member that is connected to the separated part of the doorknob mounting part, transmits an axial tensile force, and releases an axial compressive force; a footboard that is configured to be mountable below the doorknob in the hinged door, is connected to the doorknob mounting part via the linear member, and is configured to be able to rotate the doorknob by pulling the doorknob mounting part via the linear member as it is pushed down by an operator's foot; and a wheel part that is provided at the bottom of the footboard, comes into contact with a floor as the footboard is pushed down, and is configured to be able to roll on the floor as the hinged door opens and closes.SELECTED DRAWING: Figure 3
【課題】足で開き戸の錠を開放した状態で、そのまま足で開き戸を円滑に開閉する【解決手段】回転によって錠を開放するドアノブを有する開き戸を開閉するドア開閉装置は、ドアノブに取り付け可能に構成され、ドアノブの回転軸から離れた離隔部を有するドアノブ取付部と；ドアノブ取付部の離隔部に連結され、軸方向引張力を伝達し、軸方向圧縮力を逃す線状部材と；開き戸におけるドアノブより下方に取り付け可能に構成され、線状部材を介してドアノブ取付部に連結され、操作者の足による押し下げに伴って線状部材を介してドアノブ取付部を引っ張ることによってドアノブを回転可能に構成された足踏み板と；足踏み板の底部に設けられ、足踏み板の押し下げに伴って床に接触するとともに、開き戸の開閉に伴って床の上を転動可能に構成された車輪部とを備える。【選択図】図３
