Abstract
A roof drain including a base defining a channel and an axis, a gravel guard coupled to the base and including a plurality of teeth, where the gravel guard defines a plurality of gullets between the teeth, and a dome coupled to the base, where the dome includes a plurality of ribs, where the ribs define a plurality of gaps therebetween, and where each gap is radially aligned with a corresponding gullet.
Claims16
A roof drain comprising:
- a base including a throat portion having an outlet;
- a gravel guard coupled to the base and including a plurality of teeth, a plurality of gullets positioned between the teeth;
- at least one first locking member;
- and
- a dome including at least one second locking member engageable with the first locking member to releasably couple the dome to the base, the dome further including a plurality of ribs spaced apart from one another along a perimeter of the dome, the dome further including a plurality of crossbars extending between and interconnecting adjacent ribs, at least some of the crossbars being offset from one another such that there is not a group of aligned crossbars extending continuously around the dome in a circumferential direction.

A roof drain comprising:
- a base including a throat portion and a flange portion, the throat portion extending along an axis and having an outlet, the flange portion extending radially outwardly from the throat portion, the flange portion including an outer edge and an upper surface positioned in an upper plane;
- a gravel guard coupled to the base and including a plurality of teeth, a plurality of gullets positioned between the teeth, each gullet including a bottom positioned axially below the upper plane;
- and
- a dome including a plurality of ribs spaced apart from one another along a perimeter of the dome, the dome further including one or more base plates extending between at least two adjacent ribs, at least one base plate of the one or more base plates is positioned completely axially below the upper plane, the dome including a plurality of crossbars extending between and interconnecting adjacent ribs, at least some of the crossbars being axially offset from one another such that there is not a group of crossbars continuously aligned around the dome in a circumferential direction.

- a gravel guard coupled to the base and including a plurality of teeth;
- and
- a dome coupled to the base, the dome including,
- a core element aligned with the axis,
- a plurality of ribs extending radially outwardly from the core element, the ribs spaced apart from one another along a perimeter of the dome to form gaps therebetween, and
- a group of crossbars extending between and interconnecting adjacent ribs, the group of crossbars being offset from one another in a step-up pattern such that crossbars in the group of crossbars are not continuously aligned with respect to each other around the dome in a circumferential direction.
