  By the way, when people go indoors to outdoors, or conversely, when they go indoors from the outside, it is common to move through the entrance soil. It is useful to install a handrail device.

  However, although it is common to enter and exit between indoors and outdoors through the entrance soil in this way, this is not all, for example, space or route problems around the entrance (for example, handrails between entrance soils). There are many cases where it is difficult to secure the installation space of the device, or when the distance from the living part to the entrance is long and obstructs walking, etc., and it enters and exits from the opening part of the sweep window close to the living part without stopping. .

  Even when entering and exiting through the opening part of the sweep window without passing between the entrance soils in this way, there is a step between the opening part and the outdoor soil, and it is necessary to pass through this step. It is considered effective to temporarily install a handrail device that supports human traffic on the outdoor soil.

  However, when the handrail device as shown in the above-mentioned patent documents on the assumption that it is installed between entrance soils is installed between outdoor soils facing the sweep window, there are the following problems. It was.

  That is, when the handrail device is installed in the outdoor soil facing the opening portion of the sweep window, the front end of the handrail rod provided in the handrail device (usually extending forward from the column) does not interfere with the sweep window. As described above, it is necessary to arrange the front end of the handrail so that it is positioned outside the outer surface of the sweep window.

  However, when the front end of the handrail rod of the handrail device is arranged outside the outer surface of the sweep window in this way, for example, the sweep window is opened, and a person tries to go from the indoor to the outside through this. In such a case, a relatively large space is generated between the person on the indoor side and the front end of the handrail fence installed on the outdoor side. Therefore, for example, even if a person who is indoors safely walks to the opening portion of the sweep window using a handrail installed indoors, the indoor handrail and the handrail device of the handrail device are in the opening portion of the sweep window. Since the space between the front end of the heel is relatively wide, the change of the grip position from the indoor handrail to the handrail ridge and the walking during the change of the grip position become unstable, and the handrail device is inherently There is a possibility that the assumed walking support function cannot be fully exhibited (see FIGS. 3 and 9).
