Abstract
A protected drain assembly comprising a drain which is at least partially bordered by a hard surface, and which is protected by a drain cover assembly which comprises (A) a laminar sheet which (i) is on top of the drain and (ii) comprises a central portion which, when a sediment-containing liquid is placed on top of it, allows the liquid to pass through it, and (B) gaskets which (i) are attached to edges of the laminar sheet and (ii) secure the edges of the laminar sheet to the hard surface.
Claims20
A drain cover assembly which can be placed over a drain in the road and which comprises
- (A) a self-supporting laminar sheet which comprises
- (1) a central portion comprising an apertured sheet material comprising apertures which allow water to pass through the central portion,
- (2) a first side edge portion which contacts and extends from one side of the central portion,
- (3) a second edge portion which contacts and extends from an opposite side of the central portion,
- (4) a front edge portion which (i) contacts and extends from a front edge of the central portion and (ii) is attached to the first and second edge portions,
- (5) a rear edge portion which (i) contacts and extends from a rear edge of the central portion and (ii) is attached to the first and second edge portions;
- (B) a first side edge gasket which comprises (i) an inner gasket portion which contacts and lies over or under the first side edge portion of the laminar sheet and (ii) an outer gasket portion which extends away from the first side edge portion of the laminar sheet;
- and
- (C) a second side edge gasket which comprises (i) an inner gasket portion which contacts and lies over or under the second side edge portion of the laminar sheet and (ii) an outer gasket portion which extends away from the second side edge portion of the laminar sheet;
- wherein each of the side edge gasket and the second side edge gasket comprises an upstanding berm which (i) is parallel to an edge of the central portion of the laminar sheet, (ii) is between the inner gasket portion and the outer gasket portion of the gasket, and (iii) extends upwards away from the inner gasket portion and the outer gasket portion;
- and
- wherein the central portion of the laminar sheet comprises, in addition to the first sheet material which has relatively large apertures therethrough, a second sheet material which has relatively small apertures therethrough and which extends over only apart of the area of the central portion of the laminar sheet.

- and
- (E) a rear edge gasket which (i) comprises an inner gasket portion which contacts and lies over or under the rear edge portion of the laminar sheet, (ii) comprises an outer gasket portion which extends away from the front edge portion of the laminar sheet and (iii) contacts the first side edge gasket and the second side edge gasket;
- wherein
- (i) each of the side edge gasket, the second side edge gasket, the front edge gasket and the rear edge gasket
- (a) includes an upstanding berm which (i) is parallel to an edge of the central portion of the laminar sheet, (ii) is between the inner gasket portion and the outer gasket portion, (iii) extends upwards away from the inner gasket portion and the outer gasket portion, and (iii) has a height of 1-3 inch, and
- (b) has two ends, each of which is joined at a corner of the laminar sheet to another gasket so that the upstanding berm continuously surrounds the laminar sheet;
- and
- (ii) the central portion of the laminar sheet comprises, in addition to the first sheet material which has relatively large apertures therethrough, a second sheet material which has relatively small apertures therethrough and which extends over a part only of the area of the central portion of the laminar sheet.
