BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover lid handle having a simple structure which can be attached to a cover which covers an opening of a water treatment facility, and a structure for attaching the handle.

[0002]

2. Description of the Related Art There are various types of cover handles, and recently, a simple cover handle as shown in FIGS. 8 and 9 has been developed.

[0003] In this cover handle, a handle fitting 102 bent into a C-shape is accommodated in the recess 101a of the lower plate 101 formed with a recess 101a, and the upper plate 103 having an opening 103a is formed on the lower plate 101. And the two ends 102a, 1 of the handle fitting 102 are integrated by spot welding.
02a is held by a holding piece 103b of the upper plate 103 so as to be rotatable.

[0004] The attachment of such a handle for the cover is performed by the cover 1.
The lower plate 10 is formed on the upper surface of the
And the upper and lower plates 101,
This is performed by passing a metal screw (flat screw) 105 from the holes formed in the four corners of 103 to the lower surface of the cover 104, and tightening it with a metal nut 106 from the lower surface side of the cover.

[0005]

However, the above-mentioned handle for the lid requires punching and pressing the upper and lower plates 101 and 103, respectively, and furthermore, it is necessary to integrate them by spot welding, so that the manufacturing cost is high. There was a problem. In addition, since the handle 102 is in contact with the bottom surface of the concave portion 101a of the lower plate 101, there is also a problem that the handle 102 is hardly pinched by the fingertip and caused.

Further, as in the above-described mounting structure, when a metal screw 105 is passed through holes at four corners of the upper and lower plates 101 and 103 to the lower surface of the cover 104 and fastened with a metal nut 106, the metal Nut 106 or metal screw 1
Since the tip of the cover 05 protrudes from the lower surface of the cover 104, there is a problem that the upper surface of the lower cover is damaged by the tip of the screw 105 or the nut 106 when the cover 104 is stacked and packed.

SUMMARY OF THE INVENTION The present invention has been made to address the above problems, and is simple to manufacture and can reduce costs.
Moreover, it is a first object to provide a cover handle for easily raising the handle metal with a fingertip. A second object of the present invention is to provide a mounting structure for a handle for a cover which does not have to worry about damaging the upper surface of the cover with the tip of a screw even when the cover is overlaid.

[0008]

In order to achieve the first object, a cover handle according to a first aspect of the present invention has a concave groove formed in a metal substrate in a substantially U-shape. The handle fitting which is bent in the shape of a letter is housed, and both ends of the handle fitting are rotatably supported up and down, and a screw insertion hole is formed on the bottom surface of the groove. The handle is supported by the head so that the handle rises from the bottom surface of the groove.

With the cover handle having such a structure, a metal substrate having a concave groove can be obtained by a single punching press, and both a punching press and a spot welding can be performed as in the conventional cover handle. Since it is unnecessary, it can be easily manufactured and cost can be reduced.

In addition, since the handle for the cover is supported by the head of the screw inserted into the screw insertion hole of the groove of the metal substrate, the handle is raised from the bottom surface of the groove. A fingertip can be inserted under the handle, and the handle can be easily raised and lifted around the pivots at both ends thereof.

Further, when the screw insertion hole is formed in the bottom surface of the concave groove portion of the metal substrate as in the handle for the cover, the head of the screw is hidden by the handle metal and cannot be seen, so that the appearance is neat and clean. Will be better.

Next, in order to achieve the second object, in the mounting structure for a cover handle according to claim 2 of the present invention, the concave groove portion of the cover handle of claim 1 is formed on the upper surface of the cover. Along with fitting into the recess, a through-hole is formed in the recess of the cover corresponding to the screw insertion hole of the cover handle to penetrate to the lower surface of the cover,
Insert the screw from the screw insertion hole of the cover handle into the through hole,
The screw is screwed so that the tip of the screw does not protrude into the plastic nut on the lower surface side of the cover.

[0013] In such a mounting structure, the tip of the screw is screwed into the plastic nut and does not protrude to the lower surface of the cover, and the plastic nut hits the upper surface of the lower cover when the cover is overlaid. Therefore, the upper surface of the lower cover is not damaged. Also, in this mounting structure,
As described above, since the head of the screw is hidden by the handle metal and cannot be seen, the appearance is refreshed and the appearance is improved.
