Inside corner gutter piece

Abstract

An inside corner gutter piece for a roof gutter system having an angled outer wall of a center segment extending at a 45 degree angle to outer walls of two straight end segments, the outer wall of the center segment acting as a flow diverter for directing rain runoff from a roof valley into connected straight gutter sections, with a top and down turned edge acting to block a rainwater off-flow stream from flowing up and out of the outer wall of the inside corner gutter piece.

AI Technical Summary

Benefits of technology

[0012]It is an object of the present invention to provide an inside corner piece for a roof gutter system which minimizes the overflow from the gutter of rainwater running

Problems solved by technology

A particular gutter problem exists at inside corners formed at valleys on the roof by the intersection of roof sections facing different directions.

The greater volume and velocity of the flow down the valley often results in overflow out of the inside corner position of the gutter system.

A heavy rain will sometimes result in overflows notwithstanding the presence of the baffles, such that they are not completely effective.

Another approach is to provide a downspout at the inside corner to collect and immediately drain away the flow as described in U.S. published application U.S. / 2002 / 0152691; U.S. / 2001 / 0032418 and U.S. / 2003 / 0115807, but this approach requires an extra downspout at the corner and does not totally prevent an over splashes at the inside corner.

U.S. Pat. No. 2,120,395 describes a covered gutter system which employs a 45° extending wall at the corner, to increase the gutter capacity at the corner but again the presence of the cover may cause deflection of the water flow off the cover and out of the gutter system.

This shape traps debris and cause damming of flow to occur.
