[0004]

In the case of the former of the prior art, the lifting device must be prevented from falling off on the back side, and it is necessary to place the lifting device directly on the ground or when stacking a plurality of sheets. However, there is a problem that it is difficult to mount the lifting device itself. In addition, when the lifting device is attached or moved or lifted through a bar or the like when mounting the lifting device, the surface of the lid is often damaged or the corners are often damaged. In the latter case,
Since it is a manual operation, the operation itself is difficult when the lid is large and heavy.

In view of the above-mentioned problems in the prior art, an object of the present invention is to provide a lid main body with a hanging metal fitting which can be stored and used, so that the lid body can be directly placed on the ground or stacked. It is therefore an object of the present invention to provide a cover for a gutter which can extremely easily handle during lifting and transport even when performing such operations.

[0006]

According to a first aspect of the present invention, there is provided a lid body having a storage portion formed on a front surface thereof, and a hanging metal fitting with a handle attached to the lid body. The gist of the hanging metal fitting is to take a storage state in which the handle is stored in the storage section to form the same plane as the surface of the lid main body, and a use state in which the handle is projected to the surface of the lid main body.

The hanging fitting has a handle fixed to the upper end of a rod movably penetrating the lid body, has a seat plate at the lower end of the rod, and has a total length including the handle shorter than the thickness of the lid body. In this case, the lid body can have a concave portion for accommodating the seat plate formed on the back surface side.

[0008] The handle of the hanging fitting may be able to be turned upside down on the surface side of the lid body, or may be vertically inverted on the surface side of the lid body.

Further, the hanging fitting may be capable of being held in a use state.

[0010]

According to the construction of the present invention, the hanging fitting is stored in a storage portion formed on the surface of the lid main body so as to be in a storage state forming the same plane as the surface of the lid main body. In addition to being stackable, unnecessary recesses are not formed on the surface of the lid body when installed in the gutter. Further, the hanging metal fitting can be hung with a wire rope or the like and easily lifted as a whole by taking a use state in which the handle projects to the surface side of the lid body.

[0011] When the handle is fixed to the upper end of the rod with the seat plate to form the hanging bracket, the length of the hanging bracket including the handle is made shorter than the thickness of the lid body so that the hanging bracket can be used in any of the used state and the stored state. In this state, the lower end of the rod does not protrude toward the back surface of the lid body. Further, the rod can regulate the protruding height of the handle in the use state via the seat plate at the lower end portion, and the lifting stroke from the storage state of the handle to the use state can be optimally set.

If a concave portion is formed on the rear surface side of the lid body, the concave portion stores the lower portion of the rod and the seat plate, and prevents them from projecting to the rear surface side of the lid main body.

[0013] The hanging metal fitting whose handle can be raised and lowered can be used by raising the handle and can be stored by lowering the handle, and there is no need to provide a through hole in the lid body.

Since the handle can be turned upside down, the handle is turned upward half a turn to take a use state, and the handle is turned down half a turn to take up a stored state, so that the stored state and the used state can be easily switched.

[0015] The hanging bracket that can be held in the use state holds the use state in which the handle protrudes from the lid body, so that the worker can use one.
Even in the case of a person, a wire rope or the like can be easily hung on the handle, and work efficiency can be improved.
