Description

  The present invention relates to a rainwater lid that has good drainage performance and that does not cause the tires of shoes heels, sports bicycles, tricycles, or baby carriages to get stuck.

  In recent years, 90% or more of steel gratings are used for rainwater jar lids instead of concrete lids.

  However, the grating has a problem of getting stuck in the tires of sports bicycles, baby carriages or tricycles with narrow shoe heels or tire widths in the gaps, and rainwater lids installed on the side edges of roads, especially on pedestrian crossings and parks. It was inappropriate.

  In addition, when grating is used as a rainwater lid, if the amount of rain is small, litter such as fallen leaves accumulates around the grating, and if fallen leaves flow after that, it accumulates further before the accumulated fallen leaves, making it more unsightly. It becomes. Furthermore, since the opening of the grating is large, not only the dirt in the rainwater basket is completely visible, but also a source of odor emission.

  The present invention has good drainage, so that dust such as fallen leaves is less likely to stagnate, and also causes problems such as tires getting stuck during running of sports bicycles, tricycles, baby carriages, etc., and shoes heel getting stuck when walking. It is an object of the present invention to provide a rainwater lid that has an effect of suppressing odor release.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the invention according to claim 1 is provided with a top plate in which an inflow side of an inflow such as rainwater or dust is notched on a support frame. A rainwater lid is provided with a guide slope that guides the inflow under the top plate in the support frame of the part.

  According to the second aspect of the present invention, a top plate with notches on both sides is provided on a rectangular support frame, and a guide slope for guiding the inflow under the top plate is provided on the support frame at the notched portion. It is the rainwater jar lid which is characterized.

  According to a third aspect of the present invention, there is provided a guide slope which is provided with a top plate notched at an appropriate number of places on a support frame having an arbitrary shape, and guides the inflow under the top plate to the support frame at the notched portion. A rainwater lid is provided.

  A fourth aspect of the present invention is the rainwater lid according to the first to third aspects of the present invention, wherein the top of the top plate is provided with anti-slip such as unevenness and anti-slip coating.

  According to the first to third aspects of the present invention, the rainwater tank is covered with the top plate without a through hole and the guide slope, and this hinders the running of sports bicycles, baby carriages, tricycles, etc. and walking with the heel of shoes. Therefore, it is suitable as a rainwater cover provided in a pedestrian crossing or a park. Moreover, since it becomes the blindfold of the filth in a rainwater basket, it is excellent in aesthetics and generation | occurrence | production of an odor is suppressed. Furthermore, since the water flow is strengthened by the guide slope, the drainage function is better than the grating, and it is possible to provide a rainwater lid with no stagnation of dust such as fallen leaves.

  According to the fourth aspect of the present invention, the slip stopper is provided on the top surface of the top plate, so that there is an effect of suppressing the overturn.

It is a top view of Example 1 of the present invention. It is a bottom view of Example 1 of the present invention. It is the sectional view on the AA line of FIG. 1 of Example 1 of this invention. It is the BB sectional drawing of FIG. 1 of Example 1 of this invention. It is a top view of Example 2 of the present invention. It is a bottom view of Example 2 of the present invention. It is CC sectional view taken on the line of FIG. 5 of Example 2 of this invention.

  Embodiments of the present invention will be described below, but the present invention is of course not limited to the following embodiments.

  1 is a plan view of an embodiment of the present invention, FIG. 2 is a bottom view thereof, FIG. 3 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 4 is a cross-sectional view taken along line BB in FIG.

  This embodiment 1 is a lid for rainwater tanks arranged side by side in an L-shaped groove array mainly provided on the side edge of a road, and a top plate 2 notched on both sides is provided on a rectangular support frame 1, Main slopes 3a, 3a and side slopes 3b, 3b, 3b, 3b for guiding the inflow under the top plate 2 are provided on the support frame at the notched portion. A slip stopper 4 is provided.

  Since it is configured as described above, even if a sports bicycle, a baby carriage or a tricycle with a narrow tire width is run, the tire does not get stuck like a grating, and the heel of the shoe will not get stuck, It is suitable as a rainwater lid for a rainwater tank provided on a pedestrian crossing.

  Moreover, rainwater is guided to the main slope 3a and the side slope 3b and flows under the top plate 2, so that dust such as fallen leaves does not accumulate unlike the grating. Further, since the slip stopper 4 is provided, there is an effect of preventing a fall accident. In this embodiment, the anti-slip 4 is a protrusion, but anti-slip coating may be applied.

  In addition, since this rainwater cover is covered with the top plate 2 so that the inside of the rainwater cover cannot be seen, there is no discomfort to pedestrians and there is an effect of suppressing odor evaporation. As excellent.

  5 is a plan view of the second embodiment, FIG. 6 is a bottom view thereof, and FIG. 7 is a sectional view taken along the line CC of FIG.

  This embodiment 2 is suitable as a rainwater cover for a rainwater tank provided in a park, a plaza or the like. On the circular support frame 5 is provided a top plate 6 with notches around 8 places, A slope 7, 7, 7, 7, 7, 7, 7, 7 is provided on the support frame to guide the inflow under the top plate 6. Similar to the lid, a slip stopper 8 made of a protrusion is provided.

  Since it is comprised as mentioned above, since rainwater flows in into a rainwater basin from four directions, it is excellent in drainage performance. In addition, as with the rainwater jar lid of Example 1, there is no problem in walking and running. Further, since the inside of the rainwater basin is shielded from being seen from the outside, it is excellent in aesthetics and has the effect of suppressing the generation of odors, and is therefore suitable as a rainwater casket for parks and open spaces. In addition, the rainwater tank using the rainwater tank lid can be used as a temporary toilet at the time of a disaster because the notch is a handle and can be easily opened and closed.
