Abstract
A gutter for a building includes a longitudinal body having a central concave channel, a front edge and a rear edge. The concave channel defines inner and outer surfaces. A curled retaining flange is formed along the front edge and defines inner and outer surfaces. A transition portion is formed at the intersection of the concave channel and the retaining flange. Tangents of the outer surfaces of the concave channel and the retaining flange originating at the transition portion form an acute angle. If desired, a roof flange can be formed along the rear edge of the longitudinal body.
Claims20
A gutter adapted to be mounted on a building comprising:
- a longitudinal body having a central concave channel, a front edge, and a rear edge, the concave channel defining an inner surface and an outer surface;
- an outwardly curled retaining flange formed along the front edge of the concave channel, the retaining flange defining an inner surface and an outer surface and terminating in a front edge;
- a transition portion formed at the intersection of the concave channel and the retaining flange, wherein tangents of the outer surfaces of the concave channel and the retaining flange originating at the transition portion form an acute angle;
- and
- a gap formed between the transition portion and the front edge of the retaining flange such that the gap and the inner surface of the retaining flange are not visible from the ground when the gutter is mounted on a building.
A gutter adapted to be mounted on a building comprising:
- a longitudinal body having a central concave channel, a front edge, and a rear edge, the concave channel defining an inner surface and an outer surface;
- an outwardly curled retaining flange formed along the front edge of the concave channel and terminating in a front edge, the retaining flange spanning approximately two hundred seventy degrees so that a gap is formed between the front edge of the retaining flange and the front edge of the concave channel, the retaining flange defining an inner surface and an outer surface;
- and
- a transition portion formed at the intersection of the concave channel and the retaining flange.
A method for forming a gutter adapted to be mounted on a building comprising:
- (a) providing a strip of bendable material having a central portion, an inner surface, an outer surface, a front edge, and a rear edge;
- (b) bending a hem along the front edge;
- (c) bending a longitudinal concave channel in a central portion of the strip;
- (d) bending an outwardly curled retaining flange terminating in a front edge between the hem and the concave channel so that an acute angle is formed by tangents originating at an intersection of the concave channel and the retaining flange to outer surfaces of the concave channel and the retaining flange and a gap is formed between the front edge of the retaining flange and the front edge of the concave channel.
