BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain cover, a public cover, a manhole cover, and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 8 and 9, for example, a clue hole (2, 2) is formed on the upper surface of a cell lid (1) as a clue for moving the cell lid (1). A structure is provided in which a claw recess (3, 3) is formed on the inner wall surface of the cue hole (2, 2), but the claw lid (1) moves unnecessarily using the cue hole (2, 2) as a clue. In order to prevent them from being opened, a small lid (4, 4) should be opened outwardly through the hinges (5, 5) in the clue holes (2, 2) as shown by the dotted line in FIG. It is pivoted so that

Further, conventionally, instead of the above-mentioned clue holes (2, 2),
As shown in FIG. 10 and FIG. 11, a pair of through holes (6, 6) are provided in the container lid (1), and the pair of through holes (6, 6) have a U-shaped handle.
Both legs (8, 8) of (7) are slidably inserted, and a groove (9) into which the handle (7) is fitted is formed between the pair of through holes (6, 6), and the handle ( When 7) is used, a structure for pulling up is provided as shown by the dotted line in FIG.

[0004]

In the conventional example shown in FIGS. 8 and 9, the hinges (5, 5) of the small lids (4, 4) are projected on the upper surface of the cell lid (1). There is a problem that the footwear is caught when walking on the top, and in the conventional example shown in FIG. 10 and FIG. 11, the handle (7) is fitted in the groove (9) and the box lid is closed.
Although it does not protrude from the upper surface of (1), it does not protrude to both legs (8, 8) of the handle (7).
Since the through holes (6, 6) for inserting the 8) are provided, the sealing property of the container lid (1) is deteriorated, and there is a problem that the odor in the container leaks from the through holes (6, 6) to the outside. .

[0005]

As a means for solving the above conventional problems, the present invention provides a bottomed claw hole (12) on the upper surface of the lid main body, and the claw hole (12) is provided with a small lid (12). 14), the pair of left and right brackets (14A, 14A) are inserted from the lower surface of the small lid (14) to close the pair of left and right brackets.
In the lower part of (14A, 14A), the rotary shafts (14B) are respectively extended outward from the root edge (14) D of the small lid (14), and the rotary shafts (14B) are connected to the clue holes (14B). 12) slidably fitted in guide slots (13) provided on both side walls (12A, 12A) of the slide slots.
The root end side of (13) is an arc hole portion (13A) centered on the root end edge (14) D of the small lid (14), and the tip end side is a straight hole portion continuous with the arc hole portion (13A). (13B) is to provide the lid (11).

[0006]

When the cell lid (11) is to be moved, the small lids (14, 14) of the handle holes (12, 12) of the cell lid (11) are opened. In order to open the small lid (14), first, the small lid (14) is rotated upward around the root edge (14) D. At that time, the rotating shafts (14B, 14B) of the pair of left and right brackets (14A, 14A) of the small lid (14) are attached to the cue hole.
Long guide holes (1) provided on both side walls (12A, 12A) of (12, 12)
Slide in the arc hole (13A) of 3, 13) and enter the straight hole (13B). At this time, the small lid (14) is guided to the straight hole portion (13B) through the rotary shaft (14B) and pulled up obliquely upward, and the rotary shaft (14B) is pulled into the guide elongated hole (13). ), The small lid (14) is rotated upward about the rotary shaft (14B). In this way, when the small lids (14, 14) are opened, the claw holes (12, 12) are used as clues to lift and move the container lid (11).

The small lid (14, 14) is fitted in the clue hole (12, 12) and closes the clue hole (12, 12), and the small lid (14, 14) is closed.
The upper surface of 14) and the upper surface of the container lid (11) can be placed on the same plane. Also, since the cue holes (12, 12) have a bottom, it is possible to completely block the inside and outside of the basin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. Check tube socket (2
4) is formed, the drain pipes (25, 26) are connected to the receiving portions (22, 23), and the inspection tube (27) is connected to the receiving portion (24). At the upper end of the inspection cylinder (27), a tapered upper cylinder (28) whose diameter gradually increases downward is inserted and attached, and the upper cylinder (28)
A box lid (11) is attached to the. Since the upper end cylinder (28) is tapered, the mounting angle of the upper end cylinder (28) with respect to the inspection cylinder (27) can be adjusted so that the container lid (11) follows the inclination of the ground surface G.

As shown in FIG. 2, the upper surface of the main body of the above-mentioned lid (11) is provided with a non-slip embossment (11A), and is provided with a pair of left and right handed claw holes (12, 12). . Further, a groove (11B) into which a driver is inserted is formed by cutting out three places on the peripheral surface of the box lid (11), and a packing groove is further formed on the peripheral surface.
(11C) is formed.

As shown in FIGS. 4 and 5, the clue hole (1
A small lid (14) is attached to 2), but a pair of left and right brackets (14A, 14A) are extended from the lower surface of the small lid (14) to lower the pair of brackets (14A, 14A). In, the rotary shafts (14B, 14B) are extended outward from the root edge (14) D of the small lid (14). Furthermore, a handle (14C) is extended from the lower surface of the tip of the small lid (14).

On the other hand, on both side walls (12A, 12A) of the handhold hole (12), guide elongated holes (13, 13) are formed. As shown in FIG. 6, the guide elongated holes (13, 13) are formed. The root end side is an arc hole part (13A) centered on the root end edge (14) D of the small lid (14), and the tip side is a straight hole part (13B) continuous with the arc hole part (13A). Has become. The small lid (14) of the clue hole (12) is closed so as to fit in the clue hole (12), and the upper surface of the small lid (14) is covered with
It is on the same plane as the upper surface of 1). The lower surface of the tip edge (14) E of the small lid (14) is supported by the stepped portion (12B) at the periphery of the cue hole (12), and the tip edge (14) E of the small lid (14) and the cue hole. (12) A gap (15) for inserting a driver is formed between the peripheral edge and the periphery.

In the above structure, when the container lid (11) is moved, the small lid (14) of the handle hole (12) is fully opened upward as shown in FIG. 7, and the handle () of the small lid (14) is opened. 14C) is used as a clue, but the small lid (14) is first rotated upward about the root edge (14) D, and at this time, the left and right brackets of the small lid (14) are rotated.
The rotating shafts (14B, 14B) of (14A, 14A) slide on the arc holes (13A) of the guide elongated holes (13, 13) of both side walls (12A, 12A) of the cue hole (12), and then When the rotary shaft (14B) enters the straight hole portion (13B) of the guide elongated hole (13), the small lid (14) is guided to the straight hole portion (13B) through the rotary shaft (14B). When the rotary shaft (14B) reaches the tip of the elongated guide hole (13), it is fully opened upward around the rotary shaft (14B).

[0013]

Therefore, in the present invention, it is possible to provide a cue for moving the container lid without impairing the tightness of the container lid and without forming a protrusion on the upper surface of the container lid.
