Abstract

The present invention provides a system for attaching a panel to a building wall using an elongated channel. The panel has a main panel portion, a panel edge portion and a groove therebetween. The elongated channel has a body and a pair of rails. The body is attachable to the wall by a fastener. The pair of rails are integrally formed with the body, extending substantially perpendicularly from the body in the same direction. One, or both, of the rails ends in a flange that is contoured to engage the cavity formed by the groove when the panel edge portion is bent around the groove and toward the rail.

Claims

1. A system for attaching at least one panel to a wall, said system comprising said at least one panel and an elongated channel, said at least one panel comprising:

a main panel portion;

a panel edge portion; and

a groove between said main panel portion and said panel edge portion, the groove having a plurality of surfaces, said panel edge portion capable of being bent around said groove toward said main panel portion to form a cavity, said cavity having a cavity wall formed by said plurality of surfaces;

and said elongated channel comprising;

a body, said body being attachable to the wall by a fastener; and

a pair of rails integrally formed with said body, said pair of rails extending substantially perpendicularly from said body in the same direction, and at least one of said rails ending in a flange contoured to engage said cavity.

2. A system according to claim 1, further comprising an insert for insertion between said two rails after said at least one panel has been positioned in said channel.

3. A system according to claim 2, further comprising a backing rod inserted over said insert.

4. A system according to claim 3, further comprising a flexible sealant applied over said backing rod.

5. A method for attaching a panel to a wall using an elongated channel, the panel comprising a main panel portion, a panel edge portion and a groove therebetween, the channel comprising a body and a pair of rails integrally formed with the body, the pair of rails extending substantially perpendicularly from the body in the same direction, and at least one of the rails ending in a flange contoured to engage a cavity formed by the groove when the panel edge portion is bent around the groove toward the at least one rail, said method comprising the steps of:

fastening the body of the channel to the wall using a fastener;

partially bending the panel edge portion around the groove toward the main panel portion;

inserting the partially-bent panel edge portion between the pair of rails so that the flange of the rail abuts the groove; and

further bending the panel edge portion around the groove and toward the rail so as to engage the flange.

6. A system for attaching at least one panel to a wall, said system comprising said at least one panel and an elongated channel, said at least one panel comprising:

a main panel portion;

a panel edge portion,

wherein said panel edge portion is capable of being bent toward said main panel portion to form a cavity therebetween;

and said elongated channel comprising;

a body, said body being attachable to the wall by a fastener; and

a pair of rails integrally formed with said body, said pair of rails extending substantially perpendicularly from said body in the same direction, and at least one of said rails ending in a flange contoured to engage said cavity.
