Drain cover with mesh retaining channel
A drain cover assembly that retains mesh on its upper surface via a channel-fastening system that is integrated into the drain cover's perimeter zone. The mesh is retained on the upper surface of the drain cover in a robust and permanent fashion. The drain cover can be configured to provide structural rigidity for supporting a load applied to its upper surface. The drain cover can be adapted to allow for its use in existing or newly constructed drainage system installations. The meshed upper surface of the drain cover can be configured to be flat or raised in profile. The meshed upper surface of the drain cover prevents mosquito habitation and breeding within the associated drainage system and prevents fine debris particles from clogging the drainage system's flow conduit.
1. A drain cover assembly for use in a drainage system comprising an underground catch basin or an underground flow conduit, comprising:
a drain cover having an upper surface and lower surface, the drain cover comprising a zone around its perimeter and a grating grid within the zone, wherein the perimeter zone comprises a channel, and wherein the grating grid comprises a plurality of grating members defining openings in between, wherein the openings are configured to permit a liquid to flow into the underground catch basin or the underground flow conduit, wherein the drain cover is configured to be connected to the underground catch basin or to the underground flow conduit proximate to its lower surface;
a channel cover ring having an upper surface and a lower surface, wherein the lower surface of the channel cover ring comprises a shape to mate with a shape of the channel to allow the channel cover ring to be connected to the drain cover;
means for connecting the channel cover ring to the drain cover; and
a mesh cover, wherein the mesh cover is configured to cover the grating grid at the upper surface of the drain cover, and wherein a periphery of the mesh cover is configured to be fixed within the channel when the channel cover ring is connected to the drain cover.
2. The drain cover assembly of claim 1 , wherein the channel is on the upper surface of the drain cover.
3. The drain cover assembly of claim 2 , wherein the channel is recessed in the upper surface of the drain cover.
4. The drain cover assembly of claim 1 , wherein the upper surface of the channel cover ring is flush with the upper surface of the drain cover when the channel cover ring is connected to the drain cover.
5. The drain cover assembly of claim 1 , wherein the periphery of the mesh cover is configured to be fixed within the channel between the channel cover ring and the drain cover.
6. The drain cover assembly of claim 1 , wherein the drain cover is configured to connect to the underground catch basin or to the underground flow conduit via contact between the lower surface and a shoulder of the underground catch basin or the underground flow conduit.
7. The drain cover assembly of claim 1 , wherein the drain cover comprises an extension at its lower surface, wherein the drain cover is configured to connect to the underground catch basin or to the underground flow conduit by positioning the extension within or around the underground catch basin or the underground flow conduit.
8. The drain cover assembly of claim 7 , wherein the extension connects within or around the underground catch basin or the underground flow conduit using a friction fit.
9. The drain cover assembly of claim 1 , wherein the means for connecting the channel cover ring to the drain cover comprises screws.
10. The drain cover assembly of claim 1 , wherein the means for connecting the channel cover ring to the drain cover comprises a mechanical snap connection between the channel cover ring and the drain cover.
11. The drain cover assembly of claim 1 , wherein the means for connecting the channel cover ring to the drain cover comprises a friction fitting connection between the channel cover ring and the drain cover.
