Description
[0001] This application is a continuing application of, and claims
priority to, provisional patent application No. 60/984,543,
entitled "CLEAT" Filed Nov. 1, 2007.
[0002] The present invention relates generally to metal roof
assemblies and more particularly to a cleat apparatus to hold a
roof assembly in place on a roof substrate.
[0003] Sheet metal roofing systems are often formed by adjoining or
overlapping pieces of sheet metal. The main purpose of roofing
systems is to create a watertight seal. Accordingly, the connection
between adjoining or overlapping pieces of sheet metal must be
watertight. Also, it is desirable that the pieces be easy and quick
to install, because labor is expensive. Prior art systems
frequently require on-site bending or welding to attach sheet metal
roofing portions together. This is costly, because time consuming,
and also requires additional equipment.
[0004] The features, aspects, and advantages of the present
invention will become better understood with reference to the
following description and claims.
SUMMARY OF THE INVENTION
[0005] The present invention relates generally to sheet metal
roofing assemblies.
[0006] According to one embodiment of the present invention, a
metal roof assembly is provided comprising at least two
interlocking elongated sheet metal roofing panels, each roofing
panel having a top lock portion, a bottom lock portion, a middle
portion between the top lock portion and the bottom lock portion,
and having a left side and a right side; a cleat having a flat
cleat portion and an inverted-V-shaped cleat portion, the
inverted-V-shaped cleat portion extending from the flat cleat
portion; the cleat in the roof assembly interposed between the top
lock portion of a first interlocking elongated sheet metal roofing
panel and the bottom lock portion of a second interlocking
elongated sheet metal roofing panel, and the cleat fixedly fastened
to the bottom lock portion and a roof substrate along the flat
cleat portion, so that the bottom lock portion of the second
elongated sheet metal roofing panel accepts the top lock portion of
the first elongated sheet metal roofing panel to create a
watertight seal.
[0007] According to another embodiment of the present invention, a
metal roof assembly comprising at least two interlocking elongated
sheet metal roofing panels, each roofing panel having a top lock
portion, a bottom lock portion, a middle portion between the top
lock portion and the bottom lock portion, and having a left side
and a right side; wherein the bottom lock portion has an elbow
portion in communication with an inverted substantially-V-shaped
bottom portion, the inverted substantially-V-shaped bottom portion
in communication with a substantially flat bottom portion; wherein
the top lock portion has an open triangular flange and an inverted
substantially-U-shaped top portion; a cleat having a flat cleat
portion and an inverted substantially-V-shaped cleat portion, the
inverted substantially-V-shaped cleat portion being in
communication with the flat cleat portion, the cleat in the roof
assembly interposed between the top lock portion of a first
interlocking elongated sheet metal roofing panel and the bottom
lock portion of a second interlocking elongated sheet metal roofing
panel, and the cleat fixedly fastened to the bottom lock portion
and a roof substrate along the flat cleat portion; wherein the
elbow portion of the bottom lock portion of the second elongated
sheet metal roofing panel accepts the open triangular flange
portion of the top lock portion of the first elongated sheet metal
roofing panel to create a watertight seal.
[0008] These and other features, aspects, and advantages of the
present invention will become better understood with reference to
the following description and claims.

DETAILED DESCRIPTION OF THE INVENTION
[0016] The following detailed description is of the best currently
contemplated modes of carrying out the invention. The description
is not to be taken in a limiting sense, but is made merely for the
purpose of illustrating the general principles of the invention,
since the scope of the invention is best defined by the appended
claims.
[0017] With reference to FIGS. 1-7, a metal roof assembly is
provided comprising at least two interlocking elongated sheet metal
roofing panels (10), each roofing panel (10) having a top lock
portion (12), a bottom lock portion (14), a middle portion (18)
between the top lock portion (12) and bottom lock portion (14), and
having a left side (16) and a right side (18); and a cleat (20)
having a flat cleat portion (22) and an inverted
substantially-V-shaped cleat portion (24), the inverted
substantially-V-shaped cleat portion (24) being in communication
with the flat cleat portion (22). As depicted in FIG. 4, the cleat
(20) in the roof assembly is interposed between the top lock
portion (12) of a first interlocking elongated sheet metal roofing
panel (30) and the bottom lock portion of a second interlocking
elongated sheet metal roofing panel (32). It should be understood
that, according to a preferred embodiment, the first interlocking
elongated sheet metal roofing panel (30) is identical to a second
interlocking elongated sheet metal roofing panel (32) and a
multitude of interlocking, elongated, sheet metal roofing panels.
In that way, whatever area is required to be covered can be covered
by simply connecting more elongated sheet metal roofing panels. As
shown in FIGS. 3, 4, and 5, the cleat is fixedly fastened (by a
fastening means such as a nail or screw (28)) to the bottom lock
portion (14) and a roof substrate (34) along the flat cleat portion
(22). The cleat is not in direct communication with the roof
substrate (34), but rather the fastening means may go through the
flat portion of the cleat and the bottom lock portion (14). As
shown in FIGS. 3 and 4, a portion (in the embodiment shown, elbow
portion 36) of the bottom lock portion of the second elongated
sheet metal roofing panel (32) accepts a portion (in the embodiment
shown, open triangular flange (44)) of the top lock portion of the
first elongated sheet metal roofing panel (30) to create a
watertight seal. It should be understood that it is envisioned that
there may be any number of elongated sheet metal roofing panels.
According to a preferred embodiment, and as shown in FIG. 7, the
inverted substantially-V-shaped cleat portion (24) is at an angle
between 95 degrees and 105 degrees, preferably 102 degrees, from
the flat cleat portion (22), and a second side (50) of the inverted
substantially-V-shaped cleat portion is at an angle between 140
degrees and 160 degrees, preferably 145 degrees, from the first
side (48) of the inverted substantially-V-shaped cleat portion. The
second side (50) is also shorter than the first side (48) according
to a preferred embodiment. Also according to a preferred
embodiment, the cleat may have a step (42) and second flat portion
(54).
[0018] As shown in FIG. 5, the bottom lock portion (14) has an
elbow portion (36) in communication with an inverted
substantially-V-shaped bottom portion (38), the inverted
substantially-V-shaped portion (38) in communication with a
substantially flat bottom portion (40). The substantially flat
bottom portion (40) of the bottom lock portion (14) has at least
two holes (FIG. 1 (52)) for receipt of a fastening means (e.g., a
screw (FIG. 3 (28)). The top lock portion (12) has an open
triangular flange (44) and an inverted substantially-U-shaped
portion (46). The open triangular flange portion (44) should be
slightly smaller than the elbow portion (36) of the bottom lock
portion (14) and be received into the elbow portion (36). The open
triangular flange portion is created by folding a piece of sheet
metal twice. The triangular flange portion may also be closed
without departing from the scope of the present invention. However,
there are advantages to an open triangular flange portion,
including that the piece may easily adjust to fit into the elbow
portion (36).
[0019] There may be at least one striation (26) running parallel to
the top lock portion (12) and the bottom lock portion (14). A
striation (26) is a series of ridges, furrows, or linear marks.
According to a preferred embodiment, as shown in FIG. 5, the
striations are slightly depressed channels and run along the middle
portion (19) between the top lock portion (12) and the bottom lock
portion (14) and running from the left side to the right side (FIG.
1, (16) and (18)).
[0020] It should be understood that the foregoing relates to
preferred embodiments of the invention and that modifications may
be made without departing from the spirit and scope of the
invention as set forth in the following claims.
