Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool used for removing and covering a groove cover which is covered with a side groove of a road.

[0002]

2. Description of the Related Art When cleaning a gutter on a road, it is a great task to remove the lid that covers the gutter.
It is no exaggeration to say that it takes up most of the gutter cleaning work. The gutter lid 100 that has been left for a long time is used for the shelf frame 1 of the gutter 110.
The space between the groove 12 and 12 is completely filled with earth and sand, and a kind of adhesive effect is exhibited to firmly fix the groove lid. When removing the lid of the gutter in such a state, it is most difficult to remove the first sheet in particular, but conventionally, this is generally done by using a Kanateko.

That is, by inserting the tip of a Katateko into a notch gap 102 formed by notching one side surface of the groove lid 100 and twisting it back and forth, the groove lid is slightly displaced, and the shelf frame 112 of the side groove 110 is formed. And the side surface of the lid 10 is broken, and then the pointed tip of the Kanateko is applied to the side surface of the lid 100 by utilizing the notch gap, and one side of the lid is pushed by the force of the lever. , It is a general method to raise the lid by rotating it little by little by lifting it up.

However, such a method requires a considerable amount of skill and skill, and when the side face of the groove cover is pryed upward with the tip of the cane lever, the angle between the canate face and the side face of the groove cover is reduced. If the groove cover hits the adjacent groove cover, it will be difficult to rotate, and if the angle is increased, the frictional force between the groove cover side surface and the tip of the groove cover will be small and it will be slippery. There was a dilemma. Therefore, it is ideal that two people from both sides of the groove lid simultaneously pry up with the Katateko, but a considerable amount of practice is required for the two people to complete their movements. Also, if the Katateko slides carelessly, the groove lid will return to its original position, so it is easy for a finger or the like to be caught, and there was a danger in the work.

[0005]

SUMMARY OF THE INVENTION It is a first object of the present invention to disclose a groove lid attaching / detaching tool which can be safely used by anyone and does not require any skill to remove and attach the groove lid. A second object of the present invention is to disclose a groove lid attaching / detaching tool that enables even a weak person to attach and detach a heavy groove lid by working in pairs.
