Abstract
A drainage device for use under the floor of a building to facilitate drainage of water along a foundation of the building under the floor. The drainage device can include a corner drainage device that is capable of assuming a number of near 90 degree shapes so that the drainage device can be easily fitted to the corner of the foundation. A bridge drainage device permits more rapid installation of the drainage devices. The bridge device can be used to bridge between two drainage devices so that it is not necessary to cut the drainage devices precisely to fit on a footing of any selected length.

A corner drainage device comprising:
- a first wall member having a foundation section and a footing section,
- a second wall member having a foundation section and a footing section,
- a first hinge joining the first and second wall members, the first hinge configured to permit pivoting of one of the first and second wall members relative to the other of the first and second wall members to form a corner at the first hinge, and
- wherein the footing section of the second wall member includes:
- a foot portion comprising one or more feet projecting downward, and
- an overlap portion free of feet and configured to overlap the footing section of the first wall member when the first hinge forms the corner, the overlap portion configured to overlap the footing section of the first wall member in closely conforming engagement at infinite increments of overlap to permit formation of the corner at the first hinge.
A corner drainage device comprising:
- a first wall member having a foundation section and a footing section,
- a second wall member having a foundation section and a footing section,
- a first hinge joining the first and second wall members, the first hinge configured to permit pivoting of one of the first and second wall members relative to the other of the first and second wall members to form a corner at the first hinge, and
- wherein the footing section of the second wall member includes a substantially planar overlap portion having a different configuration than the footing section of the first wall member, the overlap portion being configured to overlap the footing section of the first wall member when the first hinge forms the corner, the overlap portion configured to overlap the footing section of the first wall member in closely conforming engagement at infinite increments of overlap to permit formation of the corner at the first hinge.
