BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an odor prevention device according to the present invention will be described in more detail based on examples.

FIG. 1 is a plan view showing an odor prevention device according to a first embodiment of the present invention, FIG. 2 is a side view of the odor prevention device, and FIG. 3 is a sectional view taken along line AA of FIG. FIG. 4 is a perspective view showing the entire form of the odor control device.

In the figure, an odor control device 10 of the first embodiment is attached to a receiving frame 2 formed in a rainwater basin 1 so as to cover an upper opening 3 of the rainwater basin 1, and substantially the entire surface thereof. Made of a flexible sheet material, in which a plate member 11 having a plurality of water holes 11a formed in the shape of an elongated hole is attached to the lower surface of the plate member 11 by a joining means 12 and an opening 13a is formed at the lower end. It is composed of a bag body 13 and an arcuate spring body 14 provided below the bag body 13 and constantly urging the opening 13a outward.

The plate member 11 is made of a stainless steel plate (SUS304), and is formed in such a size that it can be detachably mounted so as to cover the upper opening of the rainwater basin 1, and through the water passage hole 11a. Rainwater can be passed downwards. However, the dimension and shape of the water passage hole 11a, the number of the water passage hole 11a, the position of the water passage hole 11a, and the like can be appropriately designed and changed.

The joining means 12 is not limited to this as long as the bag body 13 can be attached to the lower surface of the plate member 11. For example, a means for non-detachably attaching the bag body 13 to the plate member 11 such as thermocompression bonding may be used, but if the bag body 13 is detachably attachable to the plate member 11, the bag body 13 can be attached and detached very easily. It is also preferable because it can be performed quickly. More specifically, surface fastener means, hook / hook means, button means, etc. can be exemplified.

The bag body 13 is made of a so-called vinyl thin film, and is formed in a bag shape having an opening 13a at the lower end. However, the material of the bag body 13 is not limited, and any material may be used as long as it has flexibility and is impermeable.

The arcuate spring body 14 is a piano wire provided below the bag body 13 in order to keep the bag body 13 always outwardly biased and keep the opening 13a closed. Thus, it is possible to prevent the odor from being dissipated into the atmosphere from the rainwater basin through the opening 13a. When rainwater is collected in the bag body 13 through the water passage hole 11a, the opening 13a opens due to the own weight of the collected rainwater against the elastic force of the arcuate spring body 14. Therefore, rainwater is discharged naturally. When the drainage of rainwater from the bag body 13 is completed, the opening 13a is closed again by the elastic force of the arcuate spring body 14. This process is repeated.

Next, referring to FIG. 5, which is a cross-sectional view of a main part, shows a method of using the odor control device 1 of the first embodiment and its function and effect in a state in which the odor control device 10 is attached to the rainwater basin 1. First, a detailed explanation will be given.

In the figure, the odor prevention device 10 of the first embodiment has a plate member 2 formed on a receiving frame 2 formed at a top end portion inside a side wall of the rainwater basin 1 so as to cover an upper opening 3 of the rainwater basin 1. 11 is attached, and further, a concrete upper lid 4 having a water-permeable hole, a grating metal 5 or the like is attached to the receiving frame 2. That is, the odor control device 10 is attached under the upper lid 4 or the grating metal 5.

As described above, according to the odor prevention device 10 attached to the rainwater basin 1, the inside of the rainwater basin 1 can be made to be in a state of being shielded from the outside air, whereby the space between the receiving frame 2 and the plate member 11 can be interposed. As a result, it is possible to prevent the odor in the rainwater basin 1 from being dissipated into the atmosphere.

Further, the arcuate spring body 14 provided below the bag body 13 keeps the bag body 13 always urged outward, and holds the opening 13a formed at the lower end of the bag body 13 in a closed state. By doing so, it is possible to prevent the odor from being dissipated from the rain basin 1 into the bag body 13, in other words, into the atmosphere.

When rainwater is collected in the bag body 13 through the water passage hole 11a, the opening 13a resists the elastic force of the arcuate spring body 14 due to the weight of the collected rainwater. The rainwater is naturally discharged as it opens. Then, when the above-described rainwater discharge from the bag body 13 is completed, the opening 13a is closed again by the elastic force of the arcuate spring body 14. This process is repeated.

By the way, the odor prevention device of the above-described embodiment is only a representative one according to the present invention, and various design changes can be made within the scope of the present invention. For example, the upper surface of the plate member 11 can be provided with a cushioning material typified by natural or synthetic rubber, foamed plastic, or the like. When such a configuration is adopted, the space between the plate member 11 and the receiving frame 2 can be increased. Especially, when the upper lid is made of concrete, it is extremely preferable because it has excellent airtightness and can give a cushioning effect.

As shown in FIG. 5, a punching metal 6 or an expanded metal 6 ′ is attached to the receiving frame 2, and the concrete upper lid 4 is provided so as to cover the upper surface of the punched metal 6 or the expanded metal 6 ′. Alternatively, a grating metal 5 or the like can be attached. Such an attachment is extremely preferable because it is possible to prevent cigarette butts, fallen leaves, dust and the like from entering the bag body 13 and maintain an excellent sanitary environment.
