Abstract

A liquid flow diverter ( 130 ) for a downpipe ( 120 ) includes a body ( 132 ). The body ( 132 ) includes a channel profile ( 136 ) between a first end ( 131 ) and a second end ( 133 ). The channel profile ( 136 ) includes a helix shape and allows flow of a liquid therein. The body ( 132 ) further includes a liquid outlet ( 139 ) associated with the first end ( 131 ). The liquid outlet ( 139 ) allows fluid communication of the liquid flow diverter ( 130 ) with the downpipe ( 120 ). The liquid flow diverter ( 130 ) is characterized in that the body ( 132 ) is made of a partly rigid material with the helix shaped channel profile ( 136 ) having a lead (L) of at least a height (H) of the channel profile ( 136 ) at its first end ( 131 ).

First claim

The invention claimed is:

1. A liquid flow diverter for a downpipe, comprising:
a body including a channel profile between a first end and a second end, wherein the channel profile has a helix shape and allows flow of a liquid therein;
wherein channel profile includes a pair of side walls and a bottom surface,
wherein the pair of side walls includes inner surfaces respectively and opposed outer surfaces respectively,
a liquid outlet associated with the first end of the body, wherein the liquid outlet allows fluid communication of the liquid flow diverter with the outside of the downpipe,
the body is made of a first material, with the channel profile having a lead of at least a height of the channel profile at its first end;
wherein the channel profile includes an extension for coupling around an outer side of the body, wherein the extension is made of a second material,
wherein the body either defines a recess or a mounting profile to enable assembly of the extension with the body, or
the liquid flow diverter is manufactured through a two-component molding process, wherein the second material of the extension is paired with the first material of the body.

2. The liquid flow diverter of claim 1 , wherein the first material is a partly rigid material.

3. The liquid flow diverter of claim 1 , wherein the second material is a partly rigid material.

4. The liquid flow diverter of claim 1 , wherein the channel profile circumscribes a circumference between the first end and the second end of at least 240 degrees.

5. The liquid flow diverter of claim 1 , wherein the liquid outlet is a separate part mounted to the first end of the body or is integral to the first end.

6. The liquid flow diverter of claim 1 , wherein the extension is one or more of a seal, a compression ring and flexible, water-resistant components.

7. The liquid flow diverter of claim 6 , wherein the body is made of a rigid hard plastic, and the extension is made of rubber.

8. The liquid flow diverter of claim 1 , wherein the body is made of a material selected from one or more of a polymer or a plastic, and the extension is selected from one or more of a polymer.

9. The liquid flow diverter of claim 1 , wherein the liquid flow diverter further includes a spout having ribs, wherein the ribs of the spout allow to removably couple the liquid flow diverter with the downpipe.

10. A liquid flow diverter for a downpipe, comprising:
a body including a channel profile between a first end and a second end, wherein the channel profile has a helix shape and allows flow of a liquid therein;
wherein channel profile includes a pair of side walls and a bottom surface,
wherein the pair of side walls includes inner surfaces respectively and opposed outer surfaces respectively,
a liquid outlet associated with the first end of the body, wherein the liquid outlet allows fluid communication of the liquid flow diverter with the outside of the downpipe,
the body is made of a first material, with the channel profile having a lead of at least a height of the channel profile at its first end;
wherein the channel profile includes an extension for coupling around an outer side of the body, wherein the extension is made of a second material,
wherein the liquid flow diverter further includes a spout having ribs to facilitate the mounting of a spout;
wherein the body either defines a recess or a mounting profile to enable assembly of the extension with the body, or
the liquid flow diverter is manufactured through a two-component molding process, wherein the second material of the extension is paired with the first material of the body.

11. The liquid flow diverter of claim 10 , wherein the ribs of the spout allow to removably couple the liquid flow diverter with the downpipe.
