DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS. The handrail (1) shown in the figure comprises a main body (2) composed of a pipe, a rod, and the like, and pillars (3, 4) suspended from the front and rear of the main body (2). As described above, a band plate (2A) is in contact with the lower edge of the main body (2) and is fixed with screws (2B), and the front and rear ends of the main body (2) are bent downward to allow the user to Clothing is not caught on the end of the main body (2),
The front pillar (3) is composed of a large-diameter portion (5) and a small-diameter portion (6) slidably inserted in the large-diameter portion (5). The length of the pillar (3) is adjusted by sliding the small-diameter portion (6) up and down with respect to the large-diameter portion (5), as shown in FIG. The small-diameter portion (6) is fixed to the large-diameter portion (5) by tightening the screw (7) as described above, and as shown in FIG. A flat washer (8A) is abutted, and a rubber cap (8) is attached from below. A reinforcing beam (9) extends between the large-diameter portion (5) of the front pillar (3) and the rear pillar (4).

At the lower end of the rear pillar (4), an L-shaped cross section bracket (10) consisting of a front piece (10A) and an upper piece (10B) is attached. The rubber cap (8) of the front pedestal (3), adjusted to a predetermined length corresponding to the height of the ascending frame (12), abuts the entrance floor (13), and the rear pedestal (13)
The bracket (10) of (4) abuts the front corner of the ascending frame (12),
As shown in detail in FIG. 5, the front piece (10A) of the bracket (10) is fixed to the front surface of the rising frame (12) with screws (11) or the like. When the handrail (1) is attached, the angle of the main body (2) is usually about half of the slope of the rising frame (12), for example, 18 to 19 °, and the angle of the main body (2) from the rising frame (12) is small. Height to the rear end is usually 75
Set to about 0mm. Therefore, the railing of this specific example (1)
Can be installed without the riser on the up frame (12).

FIGS. 6 to 8 show another embodiment of the present invention. In this specific example, as shown in FIG.
Is rotatably mounted on the main body (2) via bearing brackets (14, 15). Therefore, a fixed height ascending frame (12)
In the above, by adjusting the length of the front pillar (3), the inclination angle of the main body (2) can be adjusted. FIG.
A plug (16) is fitted to the lower end of the front pillar (3) as shown in (1), and an adjuster is inserted into the screw hole (16A) at the center of the plug (16).
The screw rod (17A) of (17) is screwed, and the length of the pillar (3) is finely adjusted by adjusting the degree of screwing of the screw rod (17A).

As shown in FIG. 8, the adjuster (17) has an inverted petri dish-shaped frame (18) and a mounting rod which is suspended from the inner upper surface of the frame (18) and has a spherical body (19A) formed at the tip. (19), a landing block (20) attached to the sphere (19A) of the mounting rod (19) so as to be tiltable by 360 °, and a soft plate (20) attached to the lower surface of the landing block (20). 20A)
(3) The landing block corresponding to the 360 ° inclination
(20) is tilted 360 ° to be in close contact with the entrance floor (13).

Further, in the present invention, a horizontal portion (2C) may be provided at the rear of the handrail body (2) as shown in FIG. 9, or a plastic coating may be provided as shown in FIGS.
The steel pipe (22A) treated with (22B) is used as the main body (22) of the handrail, and the pillars (3, 4) are connected to the main body (22) via the receiving portion (23) by screws (24) or the like. Is also good.

[0010]

According to the present invention, the front part of the bracket of the railing pillar is fixed to the front of the climbing frame with screws or the like, so that the handrail can be attached to the climbing frame without a kick-in portion.
