Description

[Detailed description of the invention] This invention relates to a lid for a container that improves drainage of rainwater.

It is convenient to make the lid of a large container such as a tank by dividing it into unit plates instead of building it as one piece from the beginning.

Based on this idea, it is made of a rectangular board and four connection edges that stand upright around it.These form a shallow square lid that is open at the bottom, and the board is horizontal. were used as unit plates.

However, when constructing the lid from unit plates like the one above,
Since the lid surface is flat as a whole, there is a drawback that drainage of rainwater, etc. is poor.

In order to improve this drawback, it has been proposed to use a unit plate in which the center of the substrate is bulged to a medium height and the substrate is inclined from the center toward the periphery.

The reason for this was that when the connecting edges of these unit plates were joined together to assemble the lid, it was expected that water would flow toward the groove with a ■-shaped cross section formed near the joint, which would help with drainage. It is.

However, even in this case, since the bottoms of the grooves were on the same horizontal plane, water would stagnate in the grooves, and drainage was not as good as expected.

This inventor thought to improve the above-mentioned drawbacks.

Conventionally, attempts to improve drainage at the bottom of a container have been known as attempts to improve drainage.

This attempt is described in Japanese Utility Model Application Publication No. 51-135814.

In this publication, an attempt is made to use unit plates with inclined substrates and to lower the bottom surface of a series of substrates from the periphery of the bottom toward the center.

However, if this attempt was applied directly to the lid, the water would flow toward the center of the lid, causing water to accumulate in the center and slowing down drainage, so favorable results could not be obtained.

The inventor thought that in the case of a lid, contrary to the above-mentioned attempt, it would be a good idea to let the water flow from the center towards the periphery.

They realized that in order to do this, unit plates with inclined substrates should be lined up, and the lid surface where the substrates are connected should be made into an inclined surface that becomes lower from the center of the lid toward the periphery.

Further, in this publication, an inclined edge for joining the side wall constituent unit plate of the container is attached to the higher edge of the substrate.

The lower edge of this inclined edge extends horizontally.

However, when using this unit plate to construct a lid surface that becomes lower from the center to the periphery, the side with the sloped edge will be located in the center of the lid, so a groove with a horizontal bottom will be formed in the center. It was found that water stagnation in the ditches led to poor drainage.

The inventor has found that in the case of a lid, it is better not to attach beveled edges to the edges of the substrate, but to have connecting edges depending directly from the four sides of the substrate.

This invention was made based on such knowledge.

That is, this device is made of a rectangular substrate and four connecting edges that hang down directly from its four sides, and these form a shallow rectangular lid-like body that is open at the bottom. ,
Adjacent pieces are perpendicular to each other, and the board slopes downward from one of the two opposing sides to the other, or slopes downward from one corner to the remaining three corners. A unit plate is formed by arranging a large number of such unit plates, connecting the substrates to form a lid surface, lowering the lid surface from the center of the lid toward the periphery, and fixing the connecting edges of adjacent unit plates, This is the slanted lid of the container.

The inclined lid of the container according to this invention will be explained as follows based on the drawings.

FIG. 1 is a partially cutaway perspective view showing an example of a tilted lid of a container according to this invention.

2 to 5 are partially cutaway perspective views showing an example of a unit plate used for assembling the inclined lid according to the present invention.

6 and 77 are partially cutaway perspective views showing an example of a container equipped with an inclined lid according to this invention.

In FIG. 1, the inclined lid of the container according to this invention is assembled from two types of unit plates 1 and 2.

As shown in FIG. 2, the unit board 1 includes a rectangular substrate 11,
four connecting edges 12, 13, 1 hanging directly from its four sides;
4 and 15, which form a rectangular shallow lid-like body with an opening at the bottom, and connecting edges 12 and 13.
．． 13 and 14 degrees, 14 degrees and 15 degrees, and 15 degrees and 12 are perpendicular to each other, respectively, and the substrate 11 is inclined downward from one of the two opposing sides toward the other.

The opening surface 16 of the rectangular tube formed by the four connecting edges is the substrate 1
plane 1 located parallel to 1 and thus orthogonal to the connecting edge
It is inclined to 7.

As shown in FIG. 3, the unit board 2 includes a rectangular board 11 and four connecting edges 12, 13, 14 directly hanging from its four sides.
, 15, and are similar to the unit plate 1 in that they form a rectangular shallow lid-like body that is open at the bottom, and that adjacent connecting edges are orthogonal to each other.

Unit plate 2 differs from unit plate 1 in that the substrate 11 is sloped downward from one corner d toward the remaining three corners a, b, and C.

The substrate 11 may be bent along a diagonal line connecting corners d and b.

As shown in FIG. 1, a unit board 1 of 1ea and eight unit boards 2 are arranged so that the slope of the substrate is continuous.

That is, four unit plates 2 are arranged at the four corners, the remaining four unit plates 2 are arranged diagonally adjacent to the unit plates 2 at the four corners, and the unit plates 1 are arranged between these unit plates 2. is covered.

The lid surface where the substrates of each unit board are connected is an inclined surface that becomes lower from the center toward the periphery.

Connecting edges of adjacent unit plates 1 and 2 are brought into contact with each other, and the unit plates 1 and 2 are connected by bolts (not shown) through packing.

In this way, the inclined lid of the container according to this invention is assembled.

In the above inclined lid, instead of unit plates 1 and 2,
The unit plate 3 shown in FIG. 4 and the unit plate 4 shown in FIG. 5 can be used.

The unit plate 3 is almost the same as the unit plate 1, but the connecting edge 14 is raised, the connecting edges 13 and 15 are trapezoidal, and the opening surface 16 is made orthogonal to each connecting edge.

The unit plate 4 is almost the same as the unit plate 2, but the connecting edges 14 and 15 are trapezoidal, so that the opening surface 16 is orthogonal to each connecting edge.

Each of the above unit plates can be made of metal such as iron, or glass fiber reinforced synthetic resin.

What is shown in FIG. 1 is an example of a typical embodiment of the inclined lid according to this invention.

This invention includes various embodiments in addition to the one shown in FIG.

For example, in FIG. 6, a unit plate 5 whose substrate 51 is not inclined with respect to the connection edge 52 is used in the center of the lid, and unit plates 1 and 2 are arranged around it.

In this invention, when the lid surface is lowered from the center toward the periphery, it also includes the case where there is a flat portion in part, as shown in this figure.

The container body can be assembled from unit plates 5.

In FIG. 7, the inclined lid is assembled from only the unit plate 3.

In this invention, when the lid surface is lowered from the center toward the periphery, it also includes the case where the lid surface is lowered from a straight line that crosses the center of the lid toward two sides parallel to this, as shown in this figure.

In addition, the slanted lid of the container according to this invention can be assembled by connecting the unit plates 3 or 4 with the unit plates 3 or 4 whose connecting edges are uniformly raised.

According to this idea, the unit plates with inclined substrates are lined up, and the lid surface formed by connecting the substrates is made lower from the center of the lid toward the periphery, so that rainwater or washing water that falls on the lid is immediately directed to the periphery. It flows towards the edge and falls off at the periphery.

Therefore, water on the lid is quickly removed.

Also, if there is any dirt on the lid at this time, it will be flushed away with the water.

Therefore, the debris on the lid is naturally removed.

Furthermore, since the unit plates are those in which the connecting edges are directly suspended from the four sides of the substrate, no grooves are formed in which water stagnates when the unit plates are arranged.

Therefore, drainage is carried out smoothly.

Since the tilted lid of the container according to this invention is assembled using unit plates, it is easy to assemble and can be assembled into various shapes using only a few types of unit plates.

This invention has excellent advantages as described above.
