Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a lid opening tool used for opening a lid such as a manhole, a handhole or the like.

(Prior Art) When a manhole cover or the like is fitted into a frame, it is usually fitted tightly because the space is filled with earth and sand. As a result, tools such as hooks have been used to open such lids.

This kind of tool uses a hook provided at the tip of the handle to lock it with a handle provided on the lid and pry it with a lever, or if the lid is firmly fitted, use a handle or a hammer to close the lid. After hitting my body to warm it up, I started prying it off with a lever.

However, recently, the so-called makeup lid has spread, and the makeup has been damaged when hit, making it extremely difficult to open the lid.

(Problems to be Solved by the Invention) An object of the present invention is to solve the above-mentioned problems and to facilitate the lid opening work, and the problem is especially the earth and sand or the like in which the lid is firmly fitted. An object is to provide a lid opening tool capable of removing foreign matter.

(Technical Means) In order to solve the above-mentioned problems, the present invention provides a handle 3 having a frame shape extending laterally with respect to a straight tool body 1 at a base end of the tool body 1 and a lid A. It has a flat shape such that it can be inserted into the gap C of the frame body B, and has an end portion 7 of the handle 3.
Using the step S with the blade tip inserted in the gap C with the fulcrum as a fulcrum, the prying blade 2 for prying by leverage is attached integrally to the handle 3 at a position retracted from the end 7 by the step S. It is a thing.

The prying blade 2 is formed into a flat shape such that it can be inserted into the gap C between the lid A and the frame B, and is made of a tough material to make the tool body 1
It is provided integrally with.

Providing a sharp tip 5 to the prying blade 2 facilitates insertion into the gap C. The prying blade 2 preferably has a length about the depth of the gap C. A hook portion 6 and other functional portions can be provided at the tip of the tool body 1.

(Operation) In the opening tool having such a configuration, the tool body 1 is turned upside down and the tip 5 of the prying blade 2 is inserted into the gap C between the lid A and the frame B (Fig. 4), and the gap C is formed. Move along to scrape out foreign matter clogged there (Fig. 5 (a)), or if pebbles or the like are fitted between the lid A and the frame B, the end of the end side 4 of the handle 3 The part is used as a fulcrum, and the step S with the prying blade 2 is used to pry out by lever action (FIG. 9 (b)). After heating in this way, the hook 6 can be hooked on the handle D of the lid A or the like to easily open the lid.

(Embodiment) Explaining with reference to the drawings, the tool main body 1 has a straight base end integrally formed with an inverted triangular handle 3, and a tip end thereof having a lid A.
The handle D is provided with a hook 6 that can be locked, and is made of steel, stainless steel, or other tough rod material tough.

The prying blade 2 is formed of a tough plate material into a substantially knife shape as described above, and is integrally attached to one end portion of the substantially triangular handle 3 at the base end portion with the oblique side 2a on the front end side facing outward.
A slight step S is provided between the outer side 2b following the oblique side 2a and the end 4 of the handle 3 so that the prying work by the lever can be easily performed.

When it is difficult to insert the prying blade 2 due to the hard soil clogging the space between the lid and the frame, the other end 7 of the handle 3 may be tapped with a hammer or the like, in which case the hook 6 side also serves as a grip. The handle 3 is formed by bending a bar, but in order to fix the butt end of the bar to the main body and to attach the prying blade 2 to the handle 3 by welding, the bar is made completely integral.

(Effect) Therefore, according to the present invention, when the lid body is firmly fitted to the frame body by the earth and sand, the earth and sand are scraped out from the handle end 7 by the flat prying blade 2 provided at the step S, At that time, since it can be removed by the lever action utilizing the step S, the lid opening operation is significantly facilitated, and the effect that the lid can be reliably opened without damaging the decorative lid is exerted. Furthermore, since the prying blade 2 can be used instead of the chisel,
Conventionally, it is very easy to open the lid, which can be done only by tapping and forcing it.
