| 210166000 | Concentric guard ring or rib | 8 |
| 20100126917 | CLAMP COLLAR DESIGN - A floor drain having a drain body that receives a rotatable frame with a grate. The orientation of the grate and frame about an axis of the drain body may be adjusted by rotating the frame relative to the drain body and clamping the frame in the desired orientation. Adjustments to the orientation of the grate and frame can be made to align the grate and frame with floor tiles or other flooring materials and with walls surrounding the floor drain. | 05-27-2010 |
| 20100258490 | Removably Engageable Storm Drain Inlet Screen - A storm drain inlet filter for preventing passage of particulate and solids in storm water entering a storm drainage system through an entry aperture. The device features a filter element held in place by a ring compressed against the sidewalls forming the entry aperture. Filter fabric may be included between two sidewalls fo the inlet filter. | 10-14-2010 |
| 20110031174 | FLOOR WATER TANK FILTERING DEVICE FOR THREE-IN-ONE SEWERS - A floor water tank filtering device for three-in-one sewers comprises a tank body having a receiving space at an interior thereof; a bottom of the tank body being formed with a drain hole; a filtering grid being installed at the drain hole; a top of the tank body being combined with a cover plate; the filtering grid being combined at an upper side of the drain hole of the tank body; a top of the filtering grid being provided as a supporting point of the cover; and the cover being formed by a plurality of cover plates; the cover plate being located an inner side of a top of the tank body; the cover being supported by the filtering grid so that the plurality of cover plates are formed as a plane to be placed upon a top of the tank body. | 02-10-2011 |
| 20120018362 | WEIR GRATE - A weir grate ( | 01-26-2012 |
| 20130240424 | DEVICE FOR USE WITH FLOOR DRAINS - A device configured for being received within a floor drain is provided. The device includes a basket assembly containing a liquid-soluble treatment material therein. A drain cover defines an opening that receives the basket assembly. A basket assembly lid defines at least one aperture for allowing flow of liquid into the basket assembly, the basket assembly includes a flange for cooperatively engaging a recess defined in the drain cover to thereby engage the lid with the drain cover. | 09-19-2013 |
| 20140158592 | Securable Drain Screen Having Lockable Access - A securable drain screen is provided having a rectangular frame, a lockable screen door, and upstanding screen sidewalls forming a rectangular trap with an open upper that is adapted to block large debris from entering a drain and clogging the same when deployed. Along the perimeter of the frame and positioned against each sidewall exterior surface is an extendable footer element that is threadably attached thereto and extendable outwards for bearing against the interior surface of a drain. The footers bear against the drain interior and securably position the assembly within the drain, while the lockable screen door therethrough is hinged for access through the device when snaking the drain. The hinged door includes a padlock latch for securing the door in a closed position, whereby only authorized users can remove the screen from the drain once deployed. | 06-12-2014 |
| 20140158593 | MOVABLE FILTER GRID FOR A DRAIN INLET - A movable filter grid for a drain inlet has a drain grill, an annular seat and an annular fastener. The drain grill has an annular plate and multiple support ribs. A first end of each support rib is connected to an outer circumferential edge of the annular plate, and a second end of the support rib radially extends outwards from the annular plate. An inner wall of an annular seat is securely connected to the second ends of the support ribs. The annular fastener has multiple pin holders annularly connected. Each pin holder has a through hole vertically formed through the pin holder and detachably mounted through by a pin. When the movable filter grid is applied to drain inlets on different terrains, the pins taking the form of a grating can prevent debris from blocking the drain holes. | 06-12-2014 |
| 20140231323 | DEVICE FOR USE WITH FLOOR DRAINS - In a floor drain assembly of the type including a floor drain having a collar surrounding a drainage opening installed in a recess in a floor, an improvement is provided. The improvement includes a skirt extending about the collar and secured to the collar by a fastener extending through the skirt and into the collar but not into the floor. The skirt defines an opening sized to receive a treatment material therein. A lid is configured for selectively engaging with the opening for allowing selective placement of treatment material in an area beneath the skirt. | 08-21-2014 |
