[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention tool for preventing workers, temporary roof tiles, work tools, etc. from sliding off the roof during roofing work.

[0002]

2. Description of the Related Art In the roofing work, accidents caused by workers falling, roof tiles temporarily placed, and work tools slipping off cannot be followed. To prevent a fall accident from the roof, a scaffold should be assembled and a net should be put up in the vicinity of the eaves of the roof, but the work to assemble the scaffold would be too large, and depending on the location, the scaffold could not be assembled. Sometimes.

Applicants have used multiple Ls on the roof along the eaves.
I tried to fix the metal fittings with nails and hang a net on the L-shaped metal fittings to make it a fall stop. However, if the roof of the L-shaped metal fittings was covered with the roof tiles, the metal fittings could not be removed. Only at the end you have to fit the roof tiles. This deviates from the ironing rule of roofing work in which roof tiles are piled up from the bottom of the roof slope, and we found that there was a problem that tiles could not be properly fitted in partially vacant places. The present invention discloses a fall prevention tool from a roof that can solve the above problems.

[0004]

A fall prevention tool of the present invention comprises a plurality of receiving fittings (1) fixed to a roof, and a fall prevention tool body (2) detachably attachable to each receiving fitting (1). The fall prevention tool is composed of a fall prevention net (6) or a sheet stretched over the main body, and the main body (2) is formed by projecting an upright pillar (4) at the tip of a leg plate (3). The base end of the leg plate (3) and the bracket

There is a gap (90) between the base plate (81) and the base plate (81), and the bracket (1)
Stays within the gap and does not interfere with the roofing.

The side edges of the tiles that are adjacent to each other on the left and right are stacked so as to overlap each other, and a space is created between the roof tile and the base plate (81) in the vicinity of the overlapping portion. If the leg plate (3) of the fall prevention device body (2) is located in the space, the leg plate (3) will not be hit by the roof tile.

If the space and the leg plate (3) are out of position,
Although roof tiles may be placed directly on (3), the leg plate (3) is used as a bracket.
The work of pulling down from (1) along the roof slope is
If you lift (9) a little, you can do it without any trouble, and after removing the leg plate (3), the roof tile will be in the correct position, so there is no problem. The receiving metal fitting (1) is left on the Hinode main board (81).
