The support frame (3) includes a pair of U-shaped side frames (31) in which legs (312) are integrally bent from both edges of the upper beam (311), and a pair of U-shaped side frames (31). ) Upper beam (311) and three connecting beams (32a, 32b, 32c) extended between each other. The support frame (3) may be made of any material as long as it has a strength capable of supporting a person, and is usually made of aluminum, iron,
Metal such as stainless steel, plastic, FRP, wood and the like are used. A leg end cap (313) made of plastic, rubber, or the like is attached to the lower end of each leg (312).

As shown in FIGS. 1 and 2, the tread (2)
The upper beam (311) of the side frame (31) of the support frame (3) is fitted into the arc-shaped notch (221) of the flange (22a) at step (3), and as shown in FIG. The center connecting beam (32b) of the three connecting beams in the support frame (3) is fitted into the V-shaped notch (242) of (24), and the inclined end (241) of the longitudinal rib (24) is fitted. Connecting beam at both ends between the and the flange (22a)
(32a, 32c) are fitted together, and as shown in FIG. 4, the engagement projections (222) on the back surface of the flange (22a) are engaged with the connection beams (32a, 32c).
c), the tread plate (2) is attached and fixed to the support frame (3).

[0011] The fixing rod (4) has an elongated plate shape having a step (41), and has two screw holes at the upper end. The fixing rod (4) is inserted into the fixing rod insertion hole (224) of the bracket (223) of the tread plate (2), and
The fixing rod (4) is fixed to the step (5) by screwing the screw (6) to the front surface of the step (5) through the screw hole of (4). In this way, the step portion for step portion (1) is fixed to the step portion (5) and the floor via the fixing rod (4). In the embodiment shown in FIG. 1 and FIG.
The lower end of (4) is in contact with the floor (ground), but the fixing rod is inserted into the insertion hole (224) of the tread plate bracket (223).
(4) may be slid upward and fixed to the step (5) with the lower end of the fixing rod (4) separated from the floor (ground). That is, according to the fixing rod (4), a fixing portion of the fixing rod (4) to the step portion (5) (for example, a portion where the screw (6) is easily screwed) can be arbitrarily selected. In addition, fixing according to the height of the step (5) can be performed.

[0012] The height h of the step portion for a step portion (1) is
There is no particular limitation as long as the height is set lower than the height H of (5), but it is preferable that the height is set to be approximately half of the height H of the step portion (5), specifically, 100 to 180 mm. Is preferred. The width W of the step portion for a step portion (1) is not particularly limited as long as the width is suitable for a person to go up and down, and is usually 300 to
450 mm.

[0013] The step portion for a step portion of the present invention described above (1)
According to this, the step existing in the building can be reduced, and even the elderly or sick can easily go up and down the step (5). Also, the step portion for step portion (1) is
(5), it is excellent in stability even when a person moves up and down the step portion (5) using the step portion for step portion (1) as a step platform, and has excellent stability. ) Accidents due to slippage, falls, etc. are prevented.

The present invention has been described with reference to the drawings.
However, the step for the step portion of the present invention is limited to the embodiment shown in the drawings.
Without departing from the scope of the present invention ,
Changes can be made. For example, on the support frame (3)
There may be two or four or more connecting beams,
The end cap (313) may not be required. Also, the back of the tread (2)
The notch in the center of the vertical rib (24) at may be semicircular.
Stone, both ends of the vertical ribs (24) have been cut in a circular arc shape
Is also good.

[0015]

【The invention's effect】 The step for the step part of the present invention
