Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a footrest for lifting a wall surface, in which a finger rest is provided with a concavity and a convexity in order to improve the grip of the footrest for lifting a wall surface.
- The footrests used for conventional fl+l exterior walls, for lifting straight walls, for lifting and lowering manholes for water and sewage systems, and for lifting and lowering manholes for public tunnels such as electric cables, etc., are round shaped mainly made of steel. Alternatively, a rectangular uniform l1FrdiJ
Footrests having a mouth shape, mouth shape, or ladder shape are used. With these conventional footrests, many methods have been devised to correct the bevel when going up and down, but most of them involve the foot sliding against the footrest.

Most of the footrests are installed in near-vertical locations and are designed to go up and down vertically, and cannot be climbed diagonally like regular stairs, nor are they designed to be climbed and descended using only the feet. Therefore, when going up and down, you have to use all of your hands and feet, moving each hand and step, as if you were climbing up a rocky area.

This type of use of footrests 11i'%: When considering,
In terms of functionality, it can be used as a foothold, and the fact that it can be held in the hands is a very interesting element. Therefore, when considering the gripping strength from the perspective of a gripping part like a conventional footrest, we found that with conventional products that have a uniform cross section that waits for a hard surface, they can be gripped with a sense of security regardless of the material that makes up the surface. It is difficult to say that the shape is designed to be as easy to dig as possible. In addition, even if a non-slip handle is configured as a scaffold, it cannot function as a light component as a non-slip handle. There is a lack of consideration in all aspects, and as a lifting device like this, it is constructed from a one-sided perspective, making it a bit of a nuisance.

The present invention is intended to improve the above-mentioned drawbacks regarding footrests, and includes a lifting footrest A that has an attachment part to a wall surface and a gripping part and a foothold part that are connected to each other. A plurality of recesses approximating the thickness of the fingers are arranged side by side in the part where the finger hangs, and between the recesses, the distance between the lowest part of each recess and the lowest part of the other recess in contact with M is the same. To provide a leg latch style for lifting and lowering, in which a finger rest is provided with unevenness so that the distance is wider than the width of a finger.

The above is a diagram of the -* embodiment of the present invention! 7 Explain.

From Figure 1 I! Figure 3 shows each side of the one-step type foot hook for on-site casting according to the present invention.1 Foot hook 1 is 1.
It is made of U-shaped cedar with a rectangular surface, and the center of the U-shape is the grip part 2 and the foothold part 5, and inside the U-shaped recess, there are a plurality of recesses 4 that are approximately the thickness of a finger. arranged side by side,
The convex portions 5 forming the boundaries of each concave portion 4 have rounded ends to make it easier to grasp. Further, an anti-slip pattern 6.6 is protruded from the foothold portion 3 of the foothold portion A1. This foothold part J41 has a central shaft 7 made of iron, and is covered with polypropylene 8 except for the mounting part 7.

The recess 4 and the anti-slip pattern 6,6' are integrally formed during molding of the polypropylene 8, and are constructed independently of the shape of the mandrel 7.

The 3M recesses 4 are easy to grip when digging by hand, and the curve is set to a size close to the thickness of the finger so that the fingers do not become wedged. The distance between the lower portion and the lowest portion of the adjacent concave s4 is wider than the width of a finger. As a result, when the footrest 1 is tightened with +, the six fingers enter each recess 4, and the distance between the six fingers becomes slightly open 9, and as soon as the footrest 1 is grasped, it is automatically tightened. The distance between the six fingers is narrowed, and the fingers can be tightened tightly without causing any stress on the elbows.

The stopper pattern 6゜6' provided on the foothold part 3 is
In order to stop the sole from sliding vertically, horizontally, and diagonally when the sole is hung, X-shaped protrusions 6 and 6' are arranged side by side, and unevenness is created on the surface of the footrest part. This is what I did. As a result, the footwork is a slow movement from the beginning to the point where you stand up and hold your body! & will be able to reliably capture the body and keep the body stable when going up and down.

As described above, with the footrest fitting of the present invention, it is possible to perform gripping and footrest operations, thereby ensuring femininity when going up and down. Especially the grip part! l1) By providing the convex curve 1 on s, the action of the 9-hand Yokocho beshi rvj* and the hand to maintain the stability of the body when going up and down is strengthened -f. By widening the spacing between the concave and convex portions of the Ik hook so that the fingers are slightly apart when gripping, the hands are naturally tightened, making it possible to hold the handle securely. You can do it and it won't come off easily. By keeping your hands steady, you can prevent accidents such as slipping and falling and make it easier to get up and down.
