Hereinafter, the auxiliary handrail according to the present invention will be specifically described based on some examples.

"First Example"
FIG. 1 shows the auxiliary handrail Z1 according to the first embodiment of the present invention, and FIG. 2 shows a state in which the handrail portion 4 is removed from the auxiliary handrail Z1.

The auxiliary handrail Z1 is a handrail mainly used to support the standing up operation when a person stands up from a bed or the like, and is a rectangular plate-shaped base 1 installed on a floor surface and the base 1. On one side of the base 1 in the long side direction, the base 1 is erected substantially vertically upward from two positions separated by a predetermined dimension in the short side direction via the support bracket 6, and is provided by the connecting member 5. It is detachably attached to a support column unit 2 composed of a plurality of columns 3 and 3 integrally connected (two in this embodiment) and upper end portions 3a and 3a of each support column 3 and 3 of the handrail portion 4. It is configured to include the provided handrail portion 4.

As described above, the auxiliary handrail Z1 has the greatest feature in that the handrail portion 4 is detachably attached to the upper end portions 3a and 3a of the respective columns 3. That is, the handrail portion 4 is configured by attaching the following joints 10 to both ends of the handrail body 41 made of a straight pipe body, and a pair of left and right support columns units 2 are provided via the joints 10 and 10. It is detachably attached to the upper end 3a of the support columns 3 and the cover 3.
