In addition, the cross-sectional size of the handrail connecting portion 58 in the thickness direction of the inner wall portion 12 is smaller than the cross-sectional size of the inner wall portion 12 of the handrail body portion 56 in the thickness direction. It is formed to be smaller (shorter) than the cross-sectional size of the handrail body portion 56 .

Thereby, the handrail 10 can effectively suppress the narrowing of the effective width of the passage 14 at the portion of the column portion 20 . Moreover, since the handrail 10 is substantially linear over substantially the entire inner wall portion 12 , the handrail 10 does not impair the appearance of the passage 14 .

Further, the handrail connecting portion 58 has a substantially semicircular cross section on the passage 14 side, but the upper surface of the cut portion 52 on the contact plate 54 side is substantially flat (gently curved). Therefore, the handrail 10 can prevent a hand touching the surface of the handrail connecting portion 58 from slipping and coming off the handrail connecting portion 58 . As a result, a person passing through the passage 14 can safely pass near the pillar 20 while touching the handrail 10, so that the handrail 10 can properly assist safe passage of the passage 14. - 特許庁

It is more preferable that the handrail connecting portion 64 is arranged at a narrow interval between the notched portion 52 and the pillar portion 20 side portion (contact plate 54) so that a human hand can be easily inserted. That is, the handrail connecting portion 64 is arranged in the notch portion 52 at such a distance from the contact plate 54 that a person passing through the passage 14 can grip the handrail connecting portion 64 .

Further, the handrail connecting portion 64 is fixed by being connected to the end portion of the handrail body portion 62 on the side of the end plate 42 at both ends in the longitudinal direction. Thus, in the handrail 60 , the handrail connecting portion 64 is arranged across the column portion 20 portion, and the handrail body portion 62 is connected by the handrail connecting portion 64 .

In the handrail 60 constructed in this manner, the handrail housing portion 30 is arranged in the non-column portion 28 of the inner wall portion 12, and the handrail main body portion 62 is mounted in the handrail housing portion 30. It is possible to suppress the narrowing of the effective width of the passage 14 at the portion of the non-column portion 28 . In the handrail 60 , a handrail connecting portion 64 is arranged in the notch 52 of the column portion 20 , and the handrail connecting portion 64 is connected to each of the handrail body portions 62 . Therefore, in the handrail 60, the handrail connecting part 64 is connected to the handrail body part 62 across the part of the column part 20, so that the person passing through the passage 14 can be appropriately assisted without feeling uneasy.

Furthermore, since the cross-sectional size of the handrail connecting portion 64 arranged in the notch portion 52 is smaller than the cross-sectional size of the handrail body portion 62, the handrail connecting portion 64 at the portion of the column portion 20 reduces the effective width of the passage 14. Narrowing can be effectively suppressed.

In addition, in this embodiment and the modified example described above, the handrails 10 and 60 are installed on the inner wall portion 12 facing the passage 14 . However, the passage provided with the wall portion to which the handrail structure is applied is not limited to the corridor, and may be stairs. In this case, the handrail may be installed along the slope of the stairs on the wall facing the staircase where the stairs are installed. Moreover, the wall to which the handrail structure is applied may face not only a passageway but also a living room of a building, thereby appropriately assisting a person passing along the wall in the living room.

In addition, in the present embodiment and the modified example, a housing having a steel rigid-frame structure as a skeleton has been described as an example. However, the building to which the handrail structure is applied may be a skeleton of a steel frame structure or a skeleton of a wooden structure.
