These lengths are approximately 65 to 90 cm when the sheet member 14 is S size, approximately 90 to 130 cm when the sheet member 14 is M size, and approximately 130 to 185 cm when the sheet member 14 is L size. It can be adjusted appropriately within the range. The right pole 17 and the left pole 18 can be expanded and contracted in the same range.

(3) Support Column and Fixed Bar Member Next, the support column 12 and the fixed bar member 19 will be described. FIG. 7 is a perspective view of an essential part showing the structure of the support column 12 and the fixing structure by the fixing rod member 19.

The support column 12 can be made of, for example, metal, in addition to synthetic resin or wood. The support column 12 is a slender plate-like member, and is arranged along the vertical direction as shown in the figure. Although only one support column 12 (left side in FIG. 1) is shown in FIG. 1, a pair of support columns 12 are actually arranged to face each other. Then, the upper pole 15 and the lower pole 16 are securely supported by the support columns 12 as shown in FIGS.

The support column 12 has an upper fitting hole 55 and a lower fitting hole 56 formed therein. Each of these fitting holes 55 and 56 is a circular hole, the inner diameter of which corresponds to the outer diameter of the cap 33 provided at the end of the upper pole 15 and the lower pole 16. The cap portion 33 fits snugly.

A slide groove 57 is formed downward from the upper fitting hole 55. The slide groove 57 has a long groove shape as shown in the figure, and its groove width is equal to the inner diameter of the upper fitting hole 55. The design of the length of the groove can be changed as appropriate. Further, the depth of the slide groove 57 is set to be shallower than the depth of the upper fitting hole 55, thereby facilitating the sliding operation of the upper pole 15 described later.

A through hole 58 is provided below the upper fitting hole 55 and above the lower fitting hole 56. The through hole 58 is for fitting a guide member 59 described later in detail.

Next, the fixing bar member 19 employs three elongated nail members in this embodiment. By driving the three nail members 19 into the support columns 12 via the guide members 59, the support columns 12 are fixed to the wall surface of the landing 11 of the stairs.

FIG. 8 is a plan view of the guide member 59, and FIG. 9 is a front view. Referring to these figures, guide member 59 can be made of, for example, synthetic resin or metal, and is a columnar member whose upper part is reduced in diameter as shown in the figures. By reducing the diameter in this manner, an inclined surface 60 is formed at the upper portion, and three nail guide holes 61 are provided symmetrically below the inclined surface 60. The nail guide hole 61 penetrates the bottom surface 62 of the guide member 59 so that the guided nail member 19 projects from the bottom surface 62 and is driven into the above-mentioned wall surface or the like. Since the nail guide holes 61 are provided symmetrically in three directions, the guided nail members 19 are also driven symmetrically in three directions.
