Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to the field of
roofing assemblies and in particular to a standing seam roofing
panel.
[0003] 2. Background of the Prior Art
[0004] Standing seam roofing assemblies are well known in the art
and are in common use, particularly in commercial constructions. In
a typical standing seam roofing assembly, a pair of upstanding legs
extend from opposing longitudinal edges of the roofing panel. The
upstanding leg of a first panel is folded or bent over the
upstanding leg of an adjacent second panel to form a standing seam
assembly. The roofing panel prevents water seepage from the surface
of the roofing panels to the surface to be roofed, while the
standing seam directs water and other elements toward the edge of
the roof.
[0005] Standing seam roofing assemblies are typically joined and
secured to the roof by a clip. Typical clips include a base which
is secured to the surface to be roofed, as by screwing or nailing,
and clipping wings which are folded over the upstanding edges of
adjacent roofing panels. Each clip is secured to the surface to be
roofed between the upstanding legs of adjacent panels.
[0006] It is well known that architectural panels expand upon
heating and contract upon cooling. When clips or other securing
devices are fastened to the panels, buckling and/or damage to the
panels can result. Several prior art fastening systems have
addressed this issue with varying degrees of success.
SUMMARY OF THE INVENTION
[0007] The present invention provides a standing seam roofing
assembly including a roofing panel and an anchor. The roofing panel
has a pair of upstanding legs on opposing longitudinal edges. A
first upstanding leg has a receiving lip on an outer portion
thereof with an upwardly-open channel being formed between the
receiving lip and the outer portion of the first upstanding
leg.
[0008] The anchor has a flat securing portion, or base, and a
mating portion extending upwardly from an edge of the securing
portion. The mating portion has a downwardly extending leg that is
slidably received over the receiving lip and into the panel
channel.
[0009] The anchor may be fastened to a roofing surface. Upon
expansion or contraction of the roofing panel with respect to the
anchor, the roofing panel will slide within the channel so as to
prevent buckling, tearing, or other such damage to the standing
seam roofing assembly.
[0010] The first upstanding leg of one panel is configured to be
received within the second leg of an adjacent panel so as to form a
standing seam that is substantially upright and symmetrical in
appearance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] FIG. 1 illustrates the components for a standing seam
roofing assembly in accordance with the present invention, prior to
assembly. A panel 12 has a first upstanding leg 30 at a first side
edge with a second panel 12' having a second upstanding leg 50 at
its second, opposing, edge. The panels 12 and 12' may be identical.
An anchor 20 includes a securing portion 22 and a mating portion
24. The first upstanding leg 30 of the panel 12 mates with the
securing portion 22 of anchor 20 with that junction being covered
by the second upstanding leg 50 of the second, adjacent, panel 12'
in a manner described more fully below.
[0017] FIG. 2 illustrates the roofing assembly 10 of FIG. 1 wherein
the anchor 20 is mated to the first upstanding leg 30 of the panel
12. The first upstanding leg 30 has a receiving lip 32 extending
from an outer portion 34. The receiving lip 32 terminates an
upwardly opening channel 36 which extends between the receiving lip
32 and the outer portion 34 of the first upstanding leg 30. The
receiving lip 32 and channel 36 are positioned at a lower portion
38 of the first leg 30.
[0018] The anchor 20 has a mating portion 24 that slidably engages
the channel 36, over the receiving lip 32. The mating portion 24
extends upwardly from the securing portion 22, and has a downwardly
opening channel formed by a leg. The securing portion 22 of the
anchor 20 is generally planar, so as to be securable to a surface
to be roofed. The anchor 20 may be secured to the roofing surface
such as by a nail, screw, staple, adhesive and/or any other such
suitable methods or devices, in known manner. The securing base 22
may have a plurality of apertures for receiving a fastener. Such
apertures may be elongated to allow a predetermined amount of
lateral movement of the fastened anchor. Alternatively, the
securing portion may be a solid planar surface wherein fasteners
must pierce the anchor in order to secure the anchor to the roofing
surface.
[0019] The anchor 20 may have a length that is coextensive with
that of the panel 12. Alternatively, the anchor 20 may have a
shorter length than the panel 12 such that a plurality of anchors
may be used to secure a single panel to a roofing surface.
[0020] FIG. 3 illustrates the roofing assembly 10 of FIG. 1 further
assembled wherein the first leg 30 of a panel 12 is covered by the
second leg 50 of a substantially identical adjacent panel 12'. The
second leg 50 has an upright portion 52, a top portion 54, and a
downwardly extending folding portion 56. When the second leg 50
covers the first leg 30, the top portion 54 of the second leg 50
overlays the top portion 33 of the first leg 30. The upright
portion 52 of the second leg 50 extends upwardly adjacent the
mating portion 24 of the anchor 20 and the outer portion 34 of the
first leg 30. The folding portion 56 of the second leg 50 extends
downwardly toward the panel 12.
[0021] The second leg 50 has a shorter length than the first leg
30. Thus, as the second leg 50 covers the first leg 30, the
adjacent panel 12 will be spaced from the securing portion 22 of
the anchor 20. This spacing prevents contact between the adjacent
panel and the head of the illustrated fastener. As is known in the
art, such contact will result in an undesirable "read through"
wherein the fastener dents or otherwise damages the overlying
panel.
[0022] FIG. 4 illustrates the roofing assembly 10 of FIG. 1 wherein
the second leg 50 of the adjacent panel 12 is folded. In
particular, the folding portion 56 of the second leg 50 is folded
inwardly, towards the upright portion 35 of the first leg 30 and
second leg 50. The terminus 39 of the first leg 30 is, thus,
enveloped within the top portion 54 and folding portion 56 of the
second leg 50.
[0023] FIG. 5 illustrates the roofing assembly 10 of FIG. 1 wherein
the uprights of each leg (35, 52) are bent downwardly. The uprights
35, 52 of the first leg 30 and second leg 50 are simultaneously
bent downwardly toward the inner portion 14 of the panel 12,
forming a seal 40.
[0024] As illustrated, the first leg 30 has an angled portion 42
positioned in a central region 46, the standing seam assembly 10
also including an upper region 60 and a lower region 62. The lower
region 62 encompasses the junction of the channels of leg 30 and
anchor 20. The upper region 60 encompasses the folds of seal 40.
The angled portion 42 of the first leg 30 provides a transition
between the upper region 60 and lower region 62 of the standing
seam assembly 10 to present substantially flush faces of the
standing seam assembly 10--the thickness of fold region 40 and
junction region 62 being generally the same. Thus, the angled
portion 42 of the first leg 30 allows the standing seam assembly 10
to be substantially symmetrical and upright in appearance on both
of its exposed side surfaces.
[0025] Obviously many modifications and variations of the present
invention are possible in light of the above teachings. It is
therefore to be understood that the invention may be practiced
otherwise than as specifically described.
