Low profile downspout extension with non-rectangular outlet
View Patent ↗A low profile downspout extension is formed in multiple segments including a flexible conduit, a splash block and an extension. The splash block transitions from a circular inlet into a low profile pentagon configuration with a central bead along the top surface of the low profile body portion to define an apex of the pentagon shape. The body portion is wider than the diameter of the circular inlet but has a height at the central bead that is more than half the diameter of the circular inlet. The body portion has ribbed side walls to strengthen the splash block without requiring internal reinforcement. The bottom surface of the splash block defines a flow path that extends generally linearly from the bottom of the inlet opening to the bottom of the pentagon-shaped outlet. An open configuration for the splash block provides an alternative above-ground splash pad structure for connecting to downspouts.

7. The downspout extension of claim 6 wherein said splash block member defines a substantially linear flow path from said inlet end to said outlet end.
8. The downspout extension of claim 7 wherein said inlet end of said flexible conduit component has a rectangular shape having a predetermined size, said downspout extension further comprising an adapter selectively connectable to said inlet end of said flexible conduit component, said adapter including an inlet end having an opening therein that is smaller than a corresponding opening in said inlet end of said flexible conduit component.
9. A low profile splash block member for connection to a discharge end of a downspout mounted on a building structure, comprising:
a circular inlet end defining a circular inlet opening having a diameter dimension;
a transition portion integrally formed with said inlet end to transition a cross-sectional configuration of said splash block member from a circular configuration to a non-rectangular and non-circular configuration; and
a body portion integrally formed with said transition portion and terminating in an outlet end, said body portion being formed with said non-rectangular and non-circular cross-sectional configuration,
wherein said body portion has an enclosed configuration with a height dimension that is smaller than said diameter dimension of said circular inlet opening and a width dimension that is larger than said diameter dimension of said circular inlet opening, and
wherein said body portion includes a generally uniform non-rectangular and non-circular cross-sectional configuration having a bottom surface, a top surface and a pair of laterally spaced side walls interconnecting said top and bottom surfaces, each of said side walls including reinforcing ribs.
10. The low profile splash block member of claim 9 wherein said top surface is formed with a longitudinally extending central bead defining an apex of said non-rectangular and non-circular cross-sectional configuration of said body portion.
11. The low profile splash block member of claim 10 wherein said non-rectangular and non-circular cross-sectional configuration has a pentagon shape with an upper apex thereof corresponding to said central bead.
12. The low profile splash block member of claim 11 wherein said height dimension of said outlet end at said central bead is greater than a corresponding height dimension of said outlet end at said side walls.
13. The low profile splash block member of claim 12 wherein said splash block member defines a substantially linear flow path from said inlet end to said outlet end.
14. The low profile splash block member of claim 13 wherein said inlet end is connected to said downspout by a flexible conduit component having an inlet end and a circular outlet end with a central flexible corrugated portion therebetween, the inlet end being connectable to said downspout and said circular outlet end being connectable to said inlet end of said splash block member.
15. The low profile splash block member of claim 9 wherein said body portion is formed in an open configuration having a bottom surface and upright side walls.
16. The low profile splash block member of claim 15 wherein said side walls are tapered from said transition portion to said outlet end with a minimum height dimension at said outlet end.
17. A downspout extension for connection to a discharge end of a downspout mounted on a building structure, comprising:
a flexible conduit component having an inlet end and a circular outlet end with a central flexible corrugated portion therebetween, the inlet end being connectable to said downspout;
a low profile splash block member including:
a circular inlet end defining a circular inlet opening having a diameter dimension said circular inlet end being connectable to said circular outlet end of said flexible conduit component;
a transition portion integrally formed with said inlet end to transition a cross-sectional configuration of said splash block member from a circular configuration to a non-rectangular configuration; and
a body portion integrally formed with said transition portion and terminating in an outlet end defining an outlet opening, said body portion being formed with said non-rectangular cross-sectional configuration; and
an extension member having a non-rectangular cross-sectional configuration mating with said body portion of said splash block to permit said extension member to be detachably connected to said outlet end of said splash block member, said cross-sectional configuration of said extension member defining a bottom surface, a top surface and laterally opposing side walls having reinforcing ribs.
18. The downspout extension of claim 17 wherein said cross-sectional configuration of said extension member is larger than a corresponding mating cross-sectional configuration of said body portion so that said extension member can be mounted around said body portion in a telescopic manner.
19. The downspout extension of claim 18 wherein said non-rectangular cross-sectional configuration has a pentagon shape with an upper apex being positioned at a center of said top surface of said body portion.
