Abstract

PROBLEM TO BE SOLVED: To provide a safe footstep by forming a throating slope which is downward slanted from a tread toward the side area in the axial direction of the tread on the rear surface of the tread and forming throating slope which is downward slanted toward the tread in the axial direction on the rear surface of the side area. SOLUTION: A footstep 1, which covers an iron-made core bar 2 with a synthetic resin 4 is formed with a tread 5, the side located on both sides of the tread and a leg 3 at the tip of the side. A throating slope 9, which is downward slanted from the tread toward the side, is formed on the rear surface of the tread 5 in the axial direction of the tread 5. A throating slope, which is downward slanted toward the leg side, is formed on the rear surface of the side in the axial direction of the side. A large number of footsteps 1 are set up on a manhole or a bulkhead in the vertical direction. Therefore, even when rainwater or water drops reach the top of the tread of one footstep, the water is prevented from dropping to the tread of a footstep at a lower elevation, which protects those who climb with the treads from slipping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footrest having a foot portion and side portions located on both sides thereof and used for a manhole or a seawall.

[0002]

2. Description of the Related Art In this type of conventional footrest, as shown in, for example, Japanese Utility Model Publication No. 4-4040, a stepping portion and side portions located on both sides thereof are located on the same plane in side view. Thus, the lower surface of the foot portion was formed straight and flat.

[0003]

By the way, in the known apparatus, a large number of such footrests are vertically arranged on a manhole or a seawall, and the manhole or the seawall is used by using the footwear. When ascending or descending, the upper surface of each foot portion may be moistened with water in some cases, and there is a possibility that the climber may slide his / her foot off the foot portion and step off.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to raise and lower a person's foot when ascending and descending using a footrest. An object of the present invention is to provide a footrest that can ascend and descend in a stable state while minimizing slipping from a foot portion.

[0005]

In order to achieve the above-mentioned object, a footrest according to the present invention steps on a drainage slope which inclines downward from the footstep to the side in the axial direction of the footstep. A draining gradient is formed on the back surface of the side portion and is formed on the back surface of the side portion and is inclined downward toward the leg side in the axial direction of the side portion.

[0006] Further, a reflector is formed by attaching and coupling a reflector element from above and below to the corner of the foot portion and the side portion.

[0007]

1 to 4 relate to one embodiment of the present invention. FIG. 1 is a plan view of a footrest, FIG. 2 is a front view thereof, FIG. 3 is a rear view, and FIG. FIG.

In the drawing, reference numeral 1 denotes the entire footrest. The footrest 1 is made of a polypropylene core except for a leg 3 with respect to an iron core 2 having a substantially U-shape in plan view. And the like. The footrest 1 is fixed to the manhole or seawall with the portion of the leg portion 3 not covered with the synthetic resin 4 embedded in, for example, a concrete of the seawall or seawall. Is what is done.

Reference numeral 5 denotes a foot step portion formed on the footrest 1,
Reference numeral 6 denotes side portions formed on both sides thereof. A large number of anti-slip patterns 7 are formed on the upper surface of the foot step portion 5 in the axial direction so that the foot of the elevating person cannot slip, and the foot step portion 5 can be gripped by the elevating person. Corrugated grip 8
Are formed in the axial direction.

A draining slope 9 is formed on the back surface of the foot portion 5 and slopes downward from the center S in the axial direction of the foot portion 5 toward both sides 6, 6. A draining slope 10 is formed on the rear surface of the side 6 and is inclined downward toward the leg side in the axial direction of the side part 6.

Since the footrest has the above-described configuration, a large number of the footrests 1 are installed vertically on a manhole or a seawall, and when the footrest 1 is used for ascending and descending. In addition, the ascending and descending person moves up and down by sequentially putting his / her foot on the foot portion 5 of the footwear 1. When the upper surfaces of the foot portions 5 of many footwears 1 are wet with water, There is a possibility that the climber may slip off the foot from the foot step and step off the foot. By the way, in the present invention, even if the rainwater or the dripped water reaches the upper surface of the foot portion 5 of one footwear 1, the water reaches the back surface of the foot portion 5 and the lower foot from the back surface. Without dropping onto the foot portion 5 of the hanging tool 1, it travels down the drainage gradient 9 formed on the back surface, and further travels down the drainage gradient 10 formed on the back surface of the side portion 6, and falls from the vicinity of the leg 3. Therefore, the foot portion 5 of the lower footrest 1 is not wetted by the rainwater or the dropped water, and only a part of the footsteps 5 of the large footrest 1 is wetted. As a whole, it becomes a safe footrest.

The reflector 11 is connected to the two reflector elements 1.
2 and 13, the reflector elements 12 and 13 are attached to the corners of the foot portion 5 and the side portion 6 from above and below to form a reflector 11, which is a dark manhole. The position and arrangement of the footrests 1 provided on the revetment inside and at night can be confirmed from any direction, and the reflector 11 can be easily replaced, providing a safer footrest.

[0013]

According to the present invention as set forth in claim 1, even if rainwater or dripping water reaches the upper surface of the step portion of one footrest, the water will be absorbed by the lower footrest. Since it does not fall on the foot step, the foot step of the lower foot equipment is not wetted by the rainwater or the dropped water, and a part of the foot foot of many foot equipment is wet. It is a safe footrest as a whole.

Further, according to the present invention described in claim 2,
While expecting the above effects, the presence of the reflector makes the replacement of the reflector easier and a safer footrest.
