In the illustrated embodiment, all three support rings 212, 216, 220, are concentric to the axis 228 and serve as reinforcement members extending between and interconnecting adjacent baffles 224. During use, the support rings 212, 216, 220 reinforce the exterior drain attachment 204 and maintain the baffles 224 in their desired orientations relative to each other. While the illustrated third support ring 220 has a third diameter that is smaller than the second diameter of the second support ring 216, it is understood that in alternative embodiments the third diameter may be equivalent to or larger than the second diameter. Furthermore, while the first and second support rings 216, 220 are shown being on the same axial plane, it is understood that in alternative embodiments different relativistic orientations may be used. Finally, while the illustrated embodiment includes three support rings 212, 216, 220 it is understood that in alternative embodiments more or fewer rings may be present. In still other embodiment, the rings 212, 216, 220 may be replaced or supplemented by a plurality of interconnecting support members extending between and being coupled to adjacent baffles 224 as needed to provide the desired support and rigidity to the overall device.
As shown in
The body 222 of each baffle 224 also includes a top edge 236 and a bottom edge 240 opposite the top edge 236. As shown in
With reference to
In the present embodiment, with reference to
The distal edge of each baffle 224 at the distal end 232 includes a substantially linear edge oriented parallel to the axis 228 at the fourth diameter. As shown in

As illustrated in
While the illustrated exterior drain attachment 204 is shown being used together with the interior drain attachment 208 (described below), it is understood that the exterior drain attachment 204 may be installed on a drain by itself without the interior drain attachment 208 being present. In still other embodiments, the exterior drain attachment 204 may be sold separately and/or together with the interior drain attachment 208 and be subsequently retrofit onto an existing drain.
With reference to
The body 276 of the interior drain attachment 208 is substantially cylindrical in shape and has a first or top end 332, a second or bottom end 340 opposite the top end 332, and defines the channel 282 extending between and open at both the first end 332 and the second end 340. In the illustrated embodiment, the first end 332 of the body 276 extends axially and vertically above the dome 26 and the exterior drain attachment 204 to provide a venting location for the channel 282. Furthermore, the second end 340 is positioned within the channel 38 of the base 18 proximate the outlet 22 (
As shown in
While the illustrated baffles 268 are planar it is also understood that in other embodiments the baffles 268 may be contoured in the vertical and/or horizontal directions. Furthermore, the exterior surfaces 348 of the baffles 268 may include ribs, grooves, and/or fins or other flow-control elements to influence the flow of water as it interacts with the interior drain attachment 208.
The distal end 286 of each baffle 268 is positioned so that, when the interior drain attachment 208 is installed in the drain 10, the distal ends 286 of each baffle 268 engage with a corresponding rib 176 (
In the illustrated embodiment, the distal end 286 includes a clasp 304 to engage the dome 26 (see
Each of the first plurality of interior baffles 268 has a generally arched exterior shape with a top contour portion 354 and a bottom contour portion 288. The top contour portion 354 of each baffle 268, in turn, includes a proximal portion 280, a distal portion 284, and a fillet 290 extending between the proximal and distal portions 280, 284. In the illustrated embodiment, proximal portion 280 is extends perpendicular to the axis 278 and is positioned relatively vertically higher than the distal portion 284 such that the fillet 290 curves downwards to merge with the distal portion 284. The distal portion 284 is generally longer in horizontal length (i.e., perpendicular to the axis 278) than the proximal portion 280. As shown in
The bottom contour portion 288 of each baffle 268 includes a concave edge originating at the body 276 and extending vertically upwardly and radially outwardly to the distal end 286. In the illustrated embodiment, the bottom contour portion 288 is of generally the same curvature as the inner surface 58 of the channel 38 of the roof drain 10 (
As shown in
Each baffle 272 of the second plurality of baffles has a substantially curved exterior profile and produces a second outer diameter that is less than the first outer diameter of the first plurality of baffles 268. By doing so, the second plurality of baffles 272 can be positioned more downstream into the channel 38 of the drain 10 when installed therein. Each of the second plurality of interior baffles 272 has an upper end 308 and a lower end 312. The upper end 308 is positioned at roughly the same height as the first end 292 of the bottom contour portion 288 of each of the first plurality of interior baffles 268. Each of the second plurality of interior baffles 272 curves downwards and outwards to a rounded edge 316 such that a first curve 320 is defined. The first curve 320 is a gradual curve. From the rounded edge 316, each of the second plurality of interior baffles 272 has a second curve 324, a relatively sharper curve than the first curve, to the lower end 312.
While the illustrated second plurality of baffles 272 includes three baffles, in other embodiments, the second plurality of interior baffles 272 may include fewer or more baffles 272 as needed including a number of baffles generally corresponding to the number of channels 352 formed by the first plurality of baffles 268.
While the illustrated exterior and interior drain attachments 204, 208 are shown as independent items capable of being installed with a separate roof drain 10 having a separate dome 26, separate gravel ring 30, and the like, it is understood that in alternative embodiments the exterior and/or interior drain attachments 204, 208 may be integrally formed together with the dome 26, gravel ring 30, base 18, and the like. It is further understood that in alternative embodiments, any combination of the exterior drain attachment 204, the interior drain attachment 208, the dome 26, the gravel ring 30, the base 18, and the like may be integrally formed together. Furthermore, while the exterior and interior drain attachments 204, 208 are shown operating together (see
With reference to
With the base 18 in place, the user may then couple the interior drain attachment 208 to the inside of the dome 26 by engaging the distal ends 286 of the baffles 268 with the crossbars 180 of the dome 26. With the interior drain attachment 208 in place, the user may then position the dome 26 on the base 18 and secure it in place with the gravel ring 30.
Finally, the user may place the exterior drain attachment 204 on top of the dome 26. In instances where a locking mechanism 264 is present, the user may also engage the locking mechanism 264 to secure the exterior drain attachment 204 to the dome 26.
During use, with continued reference to
The second stage occurs after the water has passed through the gaps 200 of the dome 26 and begins flowing into the channel 38. More specifically, water entering the roof drain 10 through the plurality of gaps 200 of the dome 26 engages the first plurality of baffles 268 and the second plurality of baffles 272 of the interior drain attachment 208 such that the baffles 268, 272 inhibit the water flow from swirling around the throat portion 42. The first two stages work in tandem to reduce stress on the plumbing system 34 caused by excessive or restricted air entrainment from vortices formed by incoming water flow. Further, the first two stages work in tandem to reduce the amount of time extraneous water is present on the roof 14 prior to entering the roof drain 10.
The third stage includes injecting air into the water flow as it exits the drain 10 (e.g., via the outlet 22) and enters the plumbing system 34. More specifically, the flow of water through the channel 38 draws air into the channel 282 via the first end 332. The drawn air then flows through the channel 282, exits the second end 340, and is injected into the water flow proximate the outlet 22. The added airflow prevents the water flow from transitioning from gravity flow to siphon flow. Siphon flow may cause undue stress on the piping system and slow down water flow through the piping system when provided in addition to gravity flow. Thus, the channel 282 in the interior drain attachment 208, in addition to the exterior plurality of baffles 224, the first plurality of baffles 268, and the second plurality of baffles 272, reduces undue stresses on the piping system and reducing the amount of time for water flow to pass through the drain.
The exterior drain attachment 1204 includes a first support ring 1210, a second support ring 1212, and a plurality of baffles 1216. The baffles 1216 are generally rectangular in shape being oriented substantially parallel to the axis 1228 in the vertical direction and substantially radially aligned in the horizontal orientation. The baffles 1216 are positioned such that they are positioned radially outside the dome 1026 while not being positioned axially above the dome 1026. Furthermore, the baffles 1216 have a vertical height that is greater than the vertical height of the dome 1026.
As shown in
As shown in
During use, the apertures 1250 are configured to allow air to enter and exit the channel 1282 at various vertical heights along the axial length of the body 1276 other than only at the top end 1332 and the bottom end 1340 thereof. By doing so, the interior drain attachment 1208 is able to more effectively prevent the formation of siphonic flow conditions within the drain assembly 1008 (e.g., the interior drain attachment 1208 can prevent the formation of siphonic flow conditions along the entire axial length thereof). For example, in instances where siphonic flow characteristics (e.g., a low-pressure region) begins to form at a location other than proximate the bottom end 1340 of the body 1276, air will be drawn into the channel 1282 through the top end 1332 and be subsequently injected into the water flow by flowing out from the apertures 1250 positioned closest to the relevant location. By doing so, the air will help prevent the formation of the pressure differentials needed for a siphonic flow to form at that particular location. As such, the interior drain attachment 1208 can specifically address siphonic flow characteristics anywhere along the axial length of the body 1276.
Still further, the apertures 1250 may also be used to allow a greater volume of air to be drawn into the channel 1282. More specifically, in conditions where one or more of the apertures 1250 are positioned above the current water level, air may be drawn into the channel 1282 via those apertures 1250. This is particularly useful in instances where the top end 1332 may become clogged or otherwise restricted.
While not shown, the interior drain attachment 1208 may also include a filter or cap attached to the top end 1332 of the body 1276. Such a cap would be configured to allow air to enter the channel 1282 while preventing debris from entering into and clogging the channel 1282. Such caps may include a screen or filter, an enclosed cap having a tortuous path, and the like.

The base 2012 also includes a first plurality of threaded apertures 2090 formed into the flange portion 2044 and outside the channel 2024. During use, the threaded apertures 2090 are configured to receive a threaded fastener therein to couple the drain attachment 2016 to the base 2012. Similarly, the base 2012 includes a second plurality of threaded apertures 2091 on the underside thereof for securing the base 2012 to a roof or other building structure.
As illustrated in
The base plate 2124 of the drain attachment 2016 is substantially disk-shaped defining an outer diameter that substantially corresponds with the outer diameter of the base 2012. The base plate 2124 includes a top surface 2126 and a bottom or underside surface 2092 opposite the top surface 2126. During use, water or other fluids flow over the top surface radially inwardly toward the weir body 2116 (discussed below) before flowing into the channel 2024.
The underside surface 2092 of the base plate 2124 is generally sized and shaped to correspond with the size and shape of the flange portion 2044 of the base plate 2124. More specifically, the underside surface 2092 includes a first annulus 2096 with a first annulus angle 2100, a second annulus 2104 with a second annulus angle 2108, and a disc portion 2112. Returning reference to
The weir body 2116 of the drain attachment 2016 extends upwardly from the top surface 2126 of the base plate 2124 and is configured to regulate the flow of water into the channel 2024. More specifically, the weir body 2116 extends away from the base plate 2124 substantially along the axis 2048 in a direction opposite the underside surface 2092. In the illustrated embodiment, the weir body 2116 extends from base plate 2124 a first height H1 that is less than the overall vertical height of the dome 2020 so that weir body 2116 can be completely positioned within the dome 2020. The first height H1 is generally configured for use with a flat roof.
In other embodiments, the weir body 2116 may have the second height that is greater than the first height H1. Such embodiments are typically configured for use with a relatively sloped roof In still other embodiments, the weir body 2116 may have a height that is less than the first height H1. In still other embodiments, the weir body 2116 may have a height that is greater the second height. In even further embodiments, the weir body 2116 may have a height infinitely between the first height H1 and the second height.
The weir body 2116 is substantially polygonal in shape forming a plurality of flats 2132 and a top support lattice 2140 at least partially enclosing the top of the weir body 2116. The lattice 2140, in turn, defines one or more openings 2128. More specifically, the weir body 2116 includes six flats 2132 such that the weir body 2116 is hexagonal. The openings 2128, in turn, are disposed at an end 2136 of the weir body 2116 opposite the base plate 2124. In the illustrated embodiments, when the drain attachment 2016 is attached to the base 2012, each opening 2128 is in fluid communication with the channel 2024 in the drain assembly 2008. Each of the flats 2132 extends substantially rectangularly between the end 2136 of the weir body 2116 and the base plate 2124. Each of the flats 2132 also shares a joint 2144 with an adjacent flat 2132.
The weir body 2116 also defines one or more flow notches 2148, each formed into a corresponding flat 2132. More specifically, each flow notch 2148 is defined by two parabolic edges 2152 generally extending between the base plate 2124 of the drain attachment 2016 and the opening 2128. In the illustrated embodiment, the parabolic edges 2152 are substantially convex edges. In other embodiments, the parabolic edges 2152 may be substantially concave edges. Each flow notch 2148 is sized and shaped to permit a rate of up to ten gallons per minute per inch of head pressure measured relative to the top surface 2126 of the base plate 2124. As such, in embodiments in which each of the flats 2132 is formed with a flow notch 2148, the drain assembly 2008 may be able to receive fluid flow at a total rate of 60 gallons per minute per inch of head pressure measured relative to the top surface 2126 of the base plate 2124.
As illustrated in
Each tooth 2156 also includes a leading angle 2180 and a trailing angle 2184. For the purposes of this application, the leading angle 2180 is generally defined as the angle at which the tooth 2156 extends from the leading point 2168 while the trailing angle 2184 is generally defined as the angle at which the tooth 2156 extends from the trailing point 2172. The leading angle 2180 is greater than the trailing angle 2184. Each tooth 2156 is also shaped so that it tapers as it extends axially from the base plate 2124 of the drain attachment 2016.
The gravel ring 2120 also includes a plurality of gullets 2188 formed between a corresponding pair of teeth 2156, between a tooth 2156 and bolt aperture 2164 (e.g., the head of the fastener positioned in the bolt aperture 2164), or between a tooth 2156 and a locking member 2160. The gullets 2188, are equally spaced about the entire circumference of the gravel ring 2120, including those gullets 2188 associated with the bolt apertures 2164 and locking members 2160.
As best illustrated in
The gravel ring 2120 additionally includes plate apertures 2190 beneath the tabs of the locking members 2160 that extend through the base plate 2124 and the underside surface 2092. More specifically, each plate aperture 2190 is sized and shaped to generally correspond to the size and shape of the locking member 2160 associated therewith. In the illustrated embodiment, each aperture 2190 is shaped so that an axial shadow cast from the associated locking member 2160 would pass completely through the plate aperture 2190 (e.g., the plate aperture 2190 is at least as large as or larger than the corresponding locking member 2160.
With reference to
The locking members 2160 of the gravel ring 2120 are configured to releasably engage with the locking members 2200 of the dome 2020. More specifically, the locking members 2160 of the gravel ring 2120 are configured to axially lock the dome 2020 against the base 2012 while also rotationally aligning the gravel ring 2120, dome 2020, and base 2012. The plate apertures 2190 provided beneath the tabs of the locking members 2160 of the gravel ring 2120 provide clearance for the locking members 2200 of the dome 2020 to selectively lock with the locking members 2160 of the gravel ring 2120.
The gravel ring 3120 includes a plurality of teeth 3156 having a substantially chevron shape. More specifically, each tooth 3156 includes a leading surface 3000 positioned proximate to and facing the exterior of the base plate 3124, and a trailing surface 3004 opposite the leading surface 3000 and facing axis 2048. Each tooth 3156 also narrows as it extends axially from the base plate 2124.
The leading surface 3000 is substantially convex, extending outwardly away from the tooth 3156. In the illustrated embodiment the leading surface 3000 includes a pair of planar surfaces set at an angle relative to one another to form a point 3008 and facing radially outwardly. More specifically, the planar surfaces are oriented such that they extend away from each other as they extend radially inwardly. In alternative embodiments, the leading surface 3000 may include a single, convex curved surface as well.
The trailing surface 3004 is substantially concave, extending inwardly into the tooth 3156. In the illustrated embodiment, the trailing surface 3004 includes a curved concave surface. However, in alternative embodiments multiple planar surfaces may also be used.

The teeth 4156 of the gravel ring 4120 are substantially rectangular in shape having a wider circumferential dimension than radial dimension. Each tooth 4156 also narrows as it extends axially from the top surface 4126 of the base plate 4124. While the illustrated teeth 4156 are rectangular, in alternative embodiments, different shapes may be used. In still other embodiments, the size and shape of the teeth 4156 may vary on a single gravel ring 4120 (e.g., a portion of the teeth 4156 are rectangular, a portion are diamond, and the like). Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects of the invention as described.
