Description

[Detailed Description of the Invention] The present invention relates to a water collection basin to which a lid is attached.

A lid is attached to the top opening of a water collection basin that receives rainwater and gray water in mid-to-high-rise buildings to prevent fallen leaves and flying debris from entering.

However, there have been cases where the lid has fallen due to being fanned by the wind. If the lid fell from a high place, there was a risk of personal injury.

The present invention solves the above-mentioned conventional drawbacks and proposes a water collection basin whose lid will not be blown away even by wind. It consists of a rectangular cylindrical square body and a lid that closes the opening of the square body.One side wall of the square body serves as a mounting wall that can be attached to the outer wall of a house, and the left and right sides are attached across the mounting wall. The upper end portions of a pair of side walls located opposite to each other are slightly bulged outward to form a stepped portion, and one of the stepped portions has an elongated bulged portion at the upper end. A substantially T-shaped locking protrusion having a bulging portion protrudes slightly above the upper end surface of the opening and is erected substantially parallel to the upper end surface, and the lid body An elongated insertion hole, which has a shape slightly smaller than the opening and through which the bulge can be inserted, is provided at a position corresponding to the locking protrusion, the longitudinal direction of which is oriented in a direction different from the longitudinal direction of the bulge. The water collection basin is configured such that the lid body can be attached to the basin body by inserting the locking protrusion into the insertion hole and rotating it left and right.

Next, an example of the present invention will be described with reference to the drawings of FIGS. 1 to 4.

The square body 1 is made up of four side walls and a bottom wall, and has a substantially rectangular cylindrical shape as a whole, and one side wall of one set of two opposing side walls is an attachment wall part that is attached to the wall surface of a building. 21, the other side wall is the front wall part 24, and the other set of side walls are the side wall parts 22,
It is said to be 22.

The front wall portion 24 is slightly inclined so that the upper end thereof protrudes outward, and the vicinity of the upper end portions of the front wall portion 24 and the side wall portions 22, 22 adjacent to both sides of the front wall portion 24 are slightly bulged outward. A step portion 23 is provided spanning the wall portion 24 and both side wall portions 22, 22, and a substantially rectangular opening 3 is formed at the upper end.

Note that the mounting wall portion 21 is not provided with a stepped portion.

A locking projection 4 is erected upward from the upper surface of a portion of the stepped portion 23 of one side wall portion 22 near the front wall portion 24, and a locking projection 4 is provided at the upper end of the locking projection 4 so as to extend laterally. A slender bulge 5 is provided, and the bulge 5 has a generally T-shape as a whole.
It protrudes upward from the upper end surface by a dimension slightly larger than the thickness of the lid 6 (described later), and is substantially parallel to the upper end surface of the side wall portion 22 .

The lid 6 has a shape slightly smaller than the shape of the opening 3, and can be dropped into the opening 3, and its peripheral edge can be locked to the step 23.

The lid 6 also has an elongated shape that allows the bulge 5 of the locking projection 4 to be inserted into the position corresponding to the locking projection 4 when the lid 6 is dropped into the opening 3. An insertion hole 7 is provided in a direction substantially parallel to the front wall portion 24 .

As shown in FIG. 4, this square body 1 has a mounting wall 21 fixed near the roof of the outer wall 8 of a house, and the end of the drain pipe 9 is inserted through the mounting wall 21.

Next, drill a hole in the bottom wall of the square body 1 and connect the rigid gutter joint 10.
is attached to the bottom wall, and the hard gutter 11 is connected to the hard gutter joint 10.

Furthermore, the procedure for closing the opening 3 of the box body 1 with the lid body 6 will be explained with reference to FIGS. 5 to 8.

Opening 3 of square body 1 fixed to outer wall 8 of house
Position the lid 6 nearby (Fig. 5), rotate the lid 1 in either the left or right direction, and insert the elongated bulge 5 of the lid locking protrusion into the elongated insertion hole 7 in the longitudinal direction. (Fig. 6), insert the bulging part 5 into the insertion hole 7 (Fig. 7), rotate the lid body 6 again, and drop the lid body 6 through the opening 3 of the cell body 1 into the step part 2. The peripheral edge of the lid 6 is locked (FIG. 8).

In this embodiment, the bulging portion 5 is approximately parallel to the side wall portion 22, and the insertion hole 7 is approximately parallel to the side wall portion 22, but the invention is not limited to this, and they may be opposite to each other. Although the part 5 and the insertion hole 7 are oriented in directions different by approximately 90 degrees, they may be oriented in directions different by 45 degrees, in other words, the cover body 6 is rotated.
The bulging part 5 and the insertion hole 7 are connected to prevent the bulging part 5 from coming out from the insertion hole 7 when dropped into the opening 3 of the
It is sufficient if they intersect.

Further, in this embodiment, the locking protrusion 4 is attached to one side wall portion 2.
Although it is provided in the part near the front wall part 24 of the step part 23 provided in 2, it is not limited to this, and it may be provided in the part near the mounting wall part 21 or in the middle. It may be provided in the stepped portion 23, and in short, it is sufficient if the locking protrusion 4 can be inserted into the insertion hole 7 of the lid 6 and the lid 6 can be dropped into the opening 3 of the rotating body 1.

Since the water collection cell of the present invention is configured as described above, the lid body can be easily attached to the opening of the cell body, and once the lid body is attached, the approximately T-shaped locking protrusion is attached to the lid. Since the lid is secured so that it does not come off through the elongated insertion hole of the body, the lid is prevented from flying away from the opening of the body even if it is blown by the wind.
