Abstract
A downspout extension has multiple connector segments at each opposing end of a flexible central portion to allow the connection of the downspout extension to substantially any conventional downspout configuration. The multiple connector segments at each respective end of the downspout extension are arranged in order of increasing size in terms of cross-sectional area from the outermost segment to the connector segment adjacent the central portion.
Rectangular segment configurations are located at one end of the downspout extension to correspond to the majority of conventional downspout configurations, while the opposing end of the downspout extension is formed with circular connector segments which for connection to drainage pipes so that the downspout extension will direct rainwater from the downspout into the drainage pipe. Cut lines are formed adjacent to each of the connector segments to facilitate the removal of the outermost connector segments when the smaller connector segments are not needed.

Description
FLEXIBLE DOWNSPOUT EXTENSION
FIELD OF THE INVENTION
This invention relates generally to an apparatus for conveying rainwater away from a downspout and, more particularly, to a downspout extension that provides a connector adapted to engage substantially any known conventional downspout configuration without restricting the flow from one end of the downspout extension to the other.
BACKGROUND OF THE INVENTION
Gutters and downspouts are mounted on most residential and commercial structures along the lower edge of the roof of the structure to receive water draining off of the roof, such as during a rainstorm. Gutters come in many different styles, including K gutter, half round gutter, or commercial box gutter, but all are generally formed with an open top through which water is received into a trough or channel that delivers the water by gravity to a downspout for discharge away from is the building structure. Gutters are often mounted on a plurality of hangers that are spaced along the length of the gutter and fastened to fascia boards by nails or screws such that the gutter is suspended from the hangers. The downspout is connected to an outlet of the gutter to provide a conduit to drain the collected rainwater from the gutter for discharge along the surface of the ground and direct the rainwater away from the building structure.
Typically, the downspout is provided with an elbow at the discharge end thereof to direct the discharged rainwater into a generally horizontal direction away from the building on which the downspout is mounted. These elbows at the discharge end of the downspout have a short length and are only effective to provide a direction for the discharge of the rainwater away from the building;
therefore, the rainwater is often discharged too close to the building and the discharged rainwater s can find a way into the basement of the building to cause cracks or leaks.
Splashblocks can be provided to receive the discharged rainwater from the downspout elbow and help direct the rainwater away from the building. Other attempts to divert the rainwater from downspouts include a non-flexible extension, which is typically a generally horizontally disposed piece of downspout affixed to the discharge end of the elbow, and a flexible downspout extension that can be bent in a desired direction to redirect the discharged rainwater.
Occasionally, a landowner will bury into the ground a drainage pipe or conduit for conveying rainwater to a remote location, such as a groundwater restoration cistern, or at least some point remotely distant from the building. The 1s downspout is then connected to the drainage pipe by the downspout extension so that the rainwater is discharged at a location that will not infiltrate into the basement of the building. Once such downspout extension can be found in U.S. Patent No.
5,813,701, granted to Christopher Noble on September 29, 1998. The Noble downspout extension is formed with multiple adaptor portions at each end of a flexible central portion. The adaptor segments at the respective ends of the downspout extension are separated by a cut line to allow the installer of the downspout extension to separate the outwardmost adaptor segment from the downspout extension so that the inner adaptor segment could be utilized to connect to the downspout. The Noble downspout extension is formed so that the adaptor segments at one end of the downspout extension will be capable of fitting into the corresponding adaptor segment at the opposing end of the downspout extension so that multiple downspout extensions can be hooked together in a serial manner.
In U. S. Patent No. 6,041,825, granted to Jeffrey Smith and Christopher Noble on March 28, 2000, the downspout extension was formed with multiple adaptor segments at each end of the flexible central portion of the downspout extension. More particularly, the adaptor segments begin with a large rectangular configuration on the outwardmost ends of the downspout extension followed inwardly by a smaller rectangular adaptor segment and then inwardly a smaller circular adaptor segment. Each adaptor segment is separable from the inwardly disposed adaptor segment by a cut line so that the outward adaptor segments can be removed. Accordingly, when the outwardmost adaptor segment was utilized to connect to the discharge end of the downspout, the rainwater, and any debris entrained within the flow of the rainwater had to pass from a larger adaptor configuration into a smaller adaptor configuration, thus forming a restriction on the flow through the downspout extension.
A differently configured flexible downspout extension is disclosed in U.
S. Patent No. 7,017,614 granted on March 28, 2006, to Stephen Handley. In the Handley downspout extension, one end of the downspout extension was formed with multiple rectangular adaptor segments arranged in decreasing sizes from the outwardmost adaptor segment to the innermost adaptor segment, while the opposing end of the downspout extension was provided with circular connector sized for attachment to a circular drainage pipe or conduit. Thus, one end of the flexible downspout extension is formed for connection to a downspout, while the opposing end is formed for connection to a drainage pipe. As with the Noble downspout extensions, the connection of the downspout to the outwardmost adaptor segment causes the flow to be constricted through decreasingly smaller adaptor segments before reaching the central flexible portion.
None of the known downspout extensions are configured to be connected to all of the known conventional sizes of downspouts. Conventional gutters and corresponding downspouts are formed in a number of different sizes and configurations resulting in the downspout being formed in a 2 inch by 3 inch or a 3 inch by 4 inch rectangular shape, a 3 inch by 3 inch square shape, or a 3 inch round or a 4 inch round shape. These five downspout configurations cover a large majority of downspouts. The most common configurations of downspouts are the 2 inch by inch and the 3 inch by 4 inch rectangular shapes. Drainage conduits are typically circular and are mostly 4 inches in diameter, although a 3 inch circular conduit can also be utilized.
It would be desirable to provide a downspout extension that is configured to provide a connector segment for each common conventional size and shape of downspout, arranged in a manner that flow through the downspout extension is not constricted as it passes into the central flexible portion that can be bent to direct the flow of rainwater into a desired direction in into a desired receiver.

DETAILED DESCRIPTION
Referring now to the drawings, a downspout extension incorporating the principles of the instant invention can best be seen. The downspout extension is formed from plastic and has a central flexible portion 15 formed in a conventional manner with corrugated pleats 17 that permit the central portion 15 to 5 bend in substantially any direction. A rectangular connector end 12 is integrally formed on one end of the flexible central portion 15, while a circular connector end 14 is integrally formed on the opposing end of the flexible central portion 15. The connector ends 12, 14 are formed with multiple connector segments, as will be described in greater detail below, for connection of the downspout extension 10 to 10 either a downspout (not shown) mounted in a conventional manner on a building, and/or to a drainage pipe (not shown) that is typically buried to provide a conduit for rainwater to be conveyed away from the building on which the downspout is mounted.
The rectangular connector end 12 is best seen in Figs. 1A, 2A and 3.
1s The rectangular connector end 12 has a first rectangular connector segment 21 at the distal end of the downspout extension 10. This first connector segment 21 is preferably sized to mount onto a two inch by three inch rectangular downspout (not shown), which is one of the conventional downspout sizes. A second rectangular connector segment 25 is formed inwardly of the first rectangular connector segment 21 so as to be located between the flexible central portion 15 and the first connector segment 21. The second connector segment 25 is sized to fit over and mount to a three inch by four inch rectangular downspout (not shown), which is also a conventional downspout size.
A first transition area 22 is integrally formed between the first connector segment 21 and the second connector segment 25 to provide a smooth transition from the first rectangular connector segment 21 and the second rectangular connector segment 25 for the flow of rainwater from the first connector segment 21 to the central portion 15. At the inward edge of the first transition area 22 lies a first cut groove 23 that is positioned at the outermost edge of the second connector segment 25. The cut groove 23 defines a thinned area of the plastic material at which a knife or other sharp instrument can be inserted to separate the first connector segment 21 and the first transition area 22 from the second rectangular connector segment 25. In this manner, the second connector segment 25 can be secured to a suitably sized downspout and the first connector segment 21 and associated transition area 22 thrown away.
A second transition area 26 is also provided between the second rectangular connector segment 25 and the inside flange 19 of the corrugated central portion 15. A second cut groove 27 is also provided at the junction of the second transition area 26 and the inside flange 19 adjacent the rectangular connector end 12 to allow the entire rectangular connector end 12 to be separated from the flexible central portion 15. The two rectangular connector segments 21, 25 represent the two most common downspout sizes utilized on residential building construction.
Thus, the downspout extension 10 is configured with the two connector segments representing the most frequently found rectangular downspouts so that in most cases one of the rectangular connector segments 21, 25 will be utilized to connect to the discharge end of a downspout.
The circular connector end 14 is formed in a similar manner to the rectangular connector end 12, but with differently configured connector segments, as will be described in greater detail below. Where the rectangular connector end 12 is configured to be utilized most frequently for connection to a downspout, the circular connector end 14 is configured to be connected most frequently to a drainage pipe that conveys rainwater away from the building on which the downspout is mounted.
Accordingly, the outermost circular connector segment 31 is sized to be connected to a three inch diameter drainage conduit (not shown). One skilled in the art will recognize that downspouts are also formed in a circular configuration having a three inch diameter. Therefore, the outermost circular connector segment 31 can be utilized to connect as needed to either a downspout or a drainage pipe.
is Inwardly from the outermost circular connector segment 31 is formed a square three inch by three inch connector segment 35 that is sized to connect to a corresponding three inch square downspout. A third transition area 32 lies between the outermost circular connector segment 31 and the square connector segment 35 to provide a smooth flow of rainwater from the smaller three inch diameter circular connector segment 31 to the slightly larger three inch square connector segment 35. A
cut groove 33 is formed at the inner end of the third transition area 32 at the edge of the square connector segment 35 to allow the outermost circular connector segment to be removed from the downspout extension 10 and allow the utilization of the square connector segment 35.
Further inwardly from the square connector segment 35 lies a second circular connector segment 41 sized to mount to a four inch drainage pipe, or to a four inch diameter, circular downspout. The most commonly used drainage pipes are four inch diameter plastic corrugated conduits that are belled at one end for connection to another section of drainage pipe (not shown), on in this situation to the four inch diameter connector segment 41. A fourth transition area 36 extends from the inner end of the square connector segment 35 to the outer edge of the four inch zo diameter circular connector segment 41, terminating in a fourth cut groove 37 that allows both the three inch diameter connector segment 31 and the three inch square connector segment 35, along with the third and fourth transition areas 32, 36, to be removed from the four inch circular connector segment 41 so that this connector segment 41 can be utilized.
A fifth transition area 42 extends from the inner edge of the four inch circular connector segment 41 to the adjacent inside flange 19 of the corrugated central portion 15 with a fifth cut groove 43 being formed at the joint between the inside flange 19 and the fifth transition area 42 to permit the removal of the entire circular connector end 14 from the central portion 15. The three and four inch diameter connector segments 31, 41 represent the most commonly utilized drainage pipe sizes, with the four inch drainage conduit being more popular than the three inch diameter version. Thus, the rectangular connector end 12 is most frequently used to connect to the discharge end of a downspout while the circular connector end 14 is most frequently utilized to connect to common drainage pipes to permit rainwater to be transported from the downspout through the downspout extension and outwardly through the drainage pipe.
5 For those instances where the circular connector end 14 is utilized to connect to a circular or to a square downspout, the opposing rectangular connector end 12 would require an appropriate rectangular-to-circular adaptor to permit connection thereof to a typical drainage pipe. Such connectors can be found in configurations that will connect to either the first or the second rectangular connector 10 segment 21, 25; however, the second rectangular connector segment 25 would be the segment preferably used so that the first rectangular connector segment 21 does not present a restriction in size for the movement of rainwater through the downspout extension 10.
One skilled in the art will recognize that the connector segments on 15 each of the connector ends 12, 14 are arranged in an increasing size, as defined by the cross-sectional area of the respective connector segment, from the distal end of the downspout extension 10 to the central corrugated portion 15. At the rectangular connector end 12, the smaller 2 x 3 connector segment 21 is outside of the larger 3 x 4 rectangular connector segment 25. At the circular connector end 14, the outermost three inch diameter circular connector segment 31 is smaller than the inwardly positioned 3 x 3 square connector segment 35, which in turn is smaller than the innermost four inch circular connector segment 41. The central corrugated portion preferably has a rectangular central opening through the portion of two and a half inches by five inches to provide a cross-sectional area that is substantially the same as the cross-sectional area of the adjacent connector segments 25, 41 at opposing ends thereof. Thus, the downspout extension 10 expands in cross-sectional area from one connector segment to another through to the flexible central portion 15 and also to the next adjacent connector segment. In situations where the downstream end of the downspout extension 10 is connected to a four inch drainage pipe, the downspout extension 10 provides a non-constrictive flow path from the downspout to the drainage pipe.
The rectangular connector end 12 is best seen in Figs. 1A, 2A and 3.
1s The rectangular connector end 12 has a first rectangular connector segment 21 at the distal end of the downspout extension 10. This first connector segment 21 is preferably sized to mount onto a two inch by three inch rectangular downspout (not shown), which is one of the conventional downspout sizes. A second rectangular connector segment 25 is formed inwardly of the first rectangular connector segment 21 so as to be located between the flexible central portion 15 and the first connector segment 21. The second connector segment 25 is sized to fit over and mount to a three inch by four inch rectangular downspout (not shown), which is also a conventional downspout size.
A first transition area 22 is integrally formed between the first connector segment 21 and the second connector segment 25 to provide a smooth transition from the first rectangular connector segment 21 and the second rectangular connector segment 25 for the flow of rainwater from the first connector segment 21 to the central portion 15. At the inward edge of the first transition area 22 lies a first cut groove 23 that is positioned at the outermost edge of the second connector segment 25. The cut groove 23 defines a thinned area of the plastic material at which a knife or other sharp instrument can be inserted to separate the first connector segment 21 and the first transition area 22 from the second rectangular connector segment 25. In this manner, the second connector segment 25 can be secured to a suitably sized downspout and the first connector segment 21 and associated transition area 22 thrown away.
A second transition area 26 is also provided between the second rectangular connector segment 25 and the inside flange 19 of the corrugated central portion 15. A second cut groove 27 is also provided at the junction of the second transition area 26 and the inside flange 19 adjacent the rectangular connector end 12 to allow the entire rectangular connector end 12 to be separated from the flexible central portion 15. The two rectangular connector segments 21, 25 represent the two most common downspout sizes utilized on residential building construction.
Thus, the downspout extension 10 is configured with the two connector segments representing the most frequently found rectangular downspouts so that in most cases one of the rectangular connector segments 21, 25 will be utilized to connect to the discharge end of a downspout.
The circular connector end 14 is formed in a similar manner to the rectangular connector end 12, but with differently configured connector segments, as will be described in greater detail below. Where the rectangular connector end 12 is configured to be utilized most frequently for connection to a downspout, the circular connector end 14 is configured to be connected most frequently to a drainage pipe that conveys rainwater away from the building on which the downspout is mounted.
Accordingly, the outermost circular connector segment 31 is sized to be connected to a three inch diameter drainage conduit (not shown). One skilled in the art will recognize that downspouts are also formed in a circular configuration having a three inch diameter. Therefore, the outermost circular connector segment 31 can be utilized to connect as needed to either a downspout or a drainage pipe.
is Inwardly from the outermost circular connector segment 31 is formed a square three inch by three inch connector segment 35 that is sized to connect to a corresponding three inch square downspout. A third transition area 32 lies between the outermost circular connector segment 31 and the square connector segment 35 to provide a smooth flow of rainwater from the smaller three inch diameter circular connector segment 31 to the slightly larger three inch square connector segment 35. A
cut groove 33 is formed at the inner end of the third transition area 32 at the edge of the square connector segment 35 to allow the outermost circular connector segment to be removed from the downspout extension 10 and allow the utilization of the square connector segment 35.
Further inwardly from the square connector segment 35 lies a second circular connector segment 41 sized to mount to a four inch drainage pipe, or to a four inch diameter, circular downspout. The most commonly used drainage pipes are four inch diameter plastic corrugated conduits that are belled at one end for connection to another section of drainage pipe (not shown), on in this situation to the four inch diameter connector segment 41. A fourth transition area 36 extends from the inner end of the square connector segment 35 to the outer edge of the four inch zo diameter circular connector segment 41, terminating in a fourth cut groove 37 that allows both the three inch diameter connector segment 31 and the three inch square connector segment 35, along with the third and fourth transition areas 32, 36, to be removed from the four inch circular connector segment 41 so that this connector segment 41 can be utilized.
A fifth transition area 42 extends from the inner edge of the four inch circular connector segment 41 to the adjacent inside flange 19 of the corrugated central portion 15 with a fifth cut groove 43 being formed at the joint between the inside flange 19 and the fifth transition area 42 to permit the removal of the entire circular connector end 14 from the central portion 15. The three and four inch diameter connector segments 31, 41 represent the most commonly utilized drainage pipe sizes, with the four inch drainage conduit being more popular than the three inch diameter version. Thus, the rectangular connector end 12 is most frequently used to connect to the discharge end of a downspout while the circular connector end 14 is most frequently utilized to connect to common drainage pipes to permit rainwater to be transported from the downspout through the downspout extension and outwardly through the drainage pipe.
5 For those instances where the circular connector end 14 is utilized to connect to a circular or to a square downspout, the opposing rectangular connector end 12 would require an appropriate rectangular-to-circular adaptor to permit connection thereof to a typical drainage pipe. Such connectors can be found in configurations that will connect to either the first or the second rectangular connector 10 segment 21, 25; however, the second rectangular connector segment 25 would be the segment preferably used so that the first rectangular connector segment 21 does not present a restriction in size for the movement of rainwater through the downspout extension 10.
One skilled in the art will recognize that the connector segments on 15 each of the connector ends 12, 14 are arranged in an increasing size, as defined by the cross-sectional area of the respective connector segment, from the distal end of the downspout extension 10 to the central corrugated portion 15. At the rectangular connector end 12, the smaller 2 x 3 connector segment 21 is outside of the larger 3 x 4 rectangular connector segment 25. At the circular connector end 14, the outermost three inch diameter circular connector segment 31 is smaller than the inwardly positioned 3 x 3 square connector segment 35, which in turn is smaller than the innermost four inch circular connector segment 41. The central corrugated portion preferably has a rectangular central opening through the portion of two and a half inches by five inches to provide a cross-sectional area that is substantially the same as the cross-sectional area of the adjacent connector segments 25, 41 at opposing ends thereof. Thus, the downspout extension 10 expands in cross-sectional area from one connector segment to another through to the flexible central portion 15 and also to the next adjacent connector segment. In situations where the downstream end of the downspout extension 10 is connected to a four inch drainage pipe, the downspout extension 10 provides a non-constrictive flow path from the downspout to the drainage pipe.
