Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to building structures and more specifically to a metal nailer with adjustable curvature, which allows a curved coping or fascia system to be attached to an edge of a building.

2. Discussion of the Prior Art

U.S. Pat. No. 6,237,301 to Paradis discloses a flexible runner. U.S. Pat. No. 7,458,188 to Mears discloses a structural alignment member. However, neither of the above patents include attachment to both an upper and lower member.

Accordingly, there is a clearly felt need in the art for a metal nailer with adjustable curvature, which allows a coping or fascia system with a curve in horizontal and/or vertical planes to be attached to an edge of a building.

SUMMARY OF THE INVENTION

The present invention provides a metal nailer with adjustable curvature, which allows a curved coping or fascia system to be attached to a curved edge of a building. The metal nailer preferably includes an upper member and a lower member. The lower member includes a lower strip of material. A first plurality of lower openings are formed adjacent a first edge of the lower strip and a second plurality lower openings are formed adjacent a second edge of the lower strip. The plurality of first and second lower openings occur at a set distance from each other in a series. The plurality of first and second openings preferably have a rectangular shape, but other shapes could also be used. A fastener opening is formed in substantially a center of two adjacent first lower openings and two adjacent second lower openings. Two lower fastener openings are formed in opposing ends of each lower strip.

An upward bent fold with a 45 degree included angle is formed in a center of each first and second lower opening. However, other values of included angles may also be used. The upward bent fold includes a first sidewall bent strip a second sidewall bent strip and a base bent strip. A height of the first and second sidewall bent strips is less than half of a height of a first lower sidewall and a second lower sidewall. A height of the base bent strip is less than half of a height of the first and second lower sidewalls. A width of the base strip is greater than a width of the first or second lower openings. The first and second edges of the lower strip are bent at a substantially 90 degree angle relative to a middle portion of the lower strip to form a U-shape. The first lower sidewall, the second lower sidewall and a lower base portion are formed from the bending.

The upper member includes an upper strip of material. The upper member includes all the features of the lower member, except that the lower fastener openings are replaced with fastener clearance openings to allow a fastener to be installed with a tool. The upper member is inserted into the lower member, such that one of the first and second upper sidewalls are inserted between the first and second lower sidewalls and moved horizontally, such that the first and second upper sidewalls contact the first and second lower sidewalls. A plurality of fasteners, such as rivets or the like are used to secure the first upper sidewall to the first lower sidewall and the second lower sidewall to the second upper sidewall. The upper member allows fascia materials to be secured to a top surface thereof.

In use, the metal nailer may be bent into a curved orientation in a horizontal plane, a vertical plane, or in both horizontal and vertical planes. The metal nailer is attached to a work surface by inserting a plurality of fasteners through the plurality of lower fastener openings into the work surface.

Accordingly, it is an object of the present invention to provide a metal nailer with adjustable curvature, which allows a coping or fascia system with a curve in horizontal and/or vertical planes to be attached to an edge of a building.

These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
