An articulated joint pivotably connects first leg and second legs. A first joint member attaches to the first leg. A second joint member attaches to the second leg. The joint members have facing abutment surfaces. Each joint member has a shaft opening receives a shaft for connecting the joint members, such that the legs may pivot between an open and a closed position. A clamping means releasably presses abutment surfaces of the joint members toward each other. A locking means releasably positively secures the joint members in at least the open position. Each joint member has a first aperture. The first aperture is radially offset from the shaft opening. The first apertures of each joint member are coaxially arranged in at least the open position. A device for supporting a person is included.
