Description
BACKGROUND OF THE INVENTION
Heretofore, metal siding has been produced with a variety of shapes
and designs with various types of interlocking and retaining joint
details. Most of these joint details provide a retaining function,
interlock or method of providing for a hidden fastening device.
These panels may be attached directly to building walls or sub
girts.
Prior to my invention, metal siding joint details satisfied only
the single interlock function and/or some other desirable feature
or features. No such panel detail provided all of these desirable
features or the multiplicity of features the unique detail joint
configuration of my invention provides.
I am aware of the following prior art patents:

The joint disclosed in U.S. Pat. No. 1,743,206 is exposed to view.
Furthermore, the method of fastening is difficult and no provision
is made for drainage of condensation.
The joint disclosed in U.S. Pat. No. 3,142,937 is also exposed to
view, requires a clip fastener, would be difficult to assemble,
provides pressure points only at the clips, and the rib is always
external.
The joint disclosed in U.S. Pat. No. 3,394,519 requires a clip and
the drainage, if any, would be questionable. Furthermore, it is
only self positioned in two directions rather than in four
directions.
U.S. Pat. No. 3,411,251 relates primarily to a roof panel hold down
means and with the design of the hold down means no provision is
made for a continuous wall panel.
The joint disclosed in U.S. Pat. No. 3,438,168 is fastened by a
clip held in place by a sheet metal screw and is not self
positioning. Furthermore, it would not prevent movement back and
forth unless fastened at one end. No provision is made for a simple
sheet metal screw fastener.
OBJECTS OF THE INVENTION
It is the general object of this invention to avoid and overcome
the foregoing and other difficulties of and objections to prior art
practices by the provision of an improved wall panel joint
assembly:
a. having a joint which provides an interlock of two adjacent
panels and which prevents side movement or front displacement of
one panel with respect to the adjacent panel;
b. has a joint which will provide drainage at the joint;
c. is self positioning with respect to an adjacent panel;
d. has a joint which will provide for a hidden fastening
device;
e. has a joint which will provide for a sheet metal screw fastener
or a snap clip fastener, both of which are hidden;
f. has a joint which will be aesthetically pleasing and not appear
as a typical lock seam joint;
g. has fastening means on only one end or edge of the panel thereby
reducing the number of fastening devices and the cost of
installation labor;
h. prevents forward movement of the female portion and sidewise
movement of the female portion of the joint assembly with respect
to the male portion of the joint assembly; and
i. positively positions the female portion of the joint assembly
with respect to the male portion of the joint assembly.
BRIEF SUMMARY OF THE INVENTION
The aforesaid objects of this invention and other objects which
will become apparent as the description proceeds are achieved by

DETAILED DESCRIPTION
With specific reference to the form of this invention illustrated
in the drawings and referring particularly to FIGS. 1 and 2, a
first panel is indicated generally by the reference numeral 10.
The first panel 10 has a first exposed panel face 12 (FIGS. 1,2)
provided on its right hand end with a first end portion or male end
14 (FIGS. 1,2) and on its left hand end with a second end portion
or female end 16 (FIGS. 1,2). For the purpose of strengthening the
first exposed panel face 12, such first exposed panel face 12 is
provided with a centrally disposed male rib 18 (FIG. 1) flanked on
opposite sides thereof by smaller reinforcing ribs 20a and 20b. The
male end 14 has a first end leg 22 (FIGS. 1,2) extending inwardly
from the first exposed panel face 12 and is provided with an
angularly disposed socket 24 (FIGS. 1,2) adjacent its mid portions.
A first retaining leg 26 (FIGS. 1,2) extends from the inner end of
the first end leg 22 substantially parallel to the first exposed
panel face 12 and extends outwardly from the right hand end of such
first exposed panel face 12.
The female end 16 (FIG. 1) of the first panel 10 has a second end
leg 28 (FIG. 1) extending inwardly from the left hand end of the
first exposed panel face 12, as viewed in FIG. 1. In addition, the
female end 16 has a generally horizontal second retaining leg 30
(FIG. 1) extending outwardly from the left hand end of the first
exposed panel face 12 and terminating in a first male protuberance
32 (FIG. 1) which cooperates with the socket 24 of an adjacent
panel 10 as now described.
As shown in FIG. 2, the female end 16a of a second panel 10a is
pivoted into position so that the second retaining leg 30a of the
female end 16a of the second panel 10a rests against the first
retaining leg 26 of the male end 14 of the first panel 10 and so
that the male protuberance 32a on the second retaining leg 30a of
the second panel 10a is fitted or locked in the socket 24 on the
male end 14 of the first panel 10 thereby defining a drainage
cavity 34 (FIG. 2). Fastener means, such as a screw type fastener
36 or the like, extends through the left hand portions of the first
retaining leg 26 of the male end 14 of the first panel 10, as
viewed in FIG. 2, into a web 38 of a C-beam type sub girt 40 to
secure the male end 14 of the panel 10 to such C-beam 40 prior to
the movement of the second panel 10a into the above described
position. As shown in FIG. 2, the male protuberance 32a of the
second panel 10a hides the fastener 36 from view.
The socket 24 on the male end 14 of the first panel 10 and the male
protuberance 32a on the female end 16a of the second panel 10a form
a cooperating means for preventing forward movement of the female
end 16a of the second panel 10a toward the first exposed panel face
12 of the first panel 10. This cooperating means is also operable
to prevent sidewise movement of the female panel end 16a of the
second panel 10a away from the first end leg 22 on the male end 14
of the first panel 10, to allow for expansion and contraction of
the female end 16a of the second panel 10a with respect to the male
end 14 of the first panel 10; and to positively position the female
end 16a of the second panel 10a with respect to the male end 14 of
the first panel.
ALTERNATIVE EMBODIMENTS
It will be understood by those skilled in the art that
alternatively, as shown in FIG. 3, a female end 16a.sup.3 of a
second panel 10a.sup.3 may be joined to a male end 14.sup.3 of a
first panel 10.sup.3. In this embodiment, the female end 16a.sup.3
of the second panel 10a.sup.3 has a first end leg 28.sup.3
projecting away from the left hand end (FIG. 3) of a second exposed
panel face 12a.sup.3 and terminating in a second retaining leg
30a.sup.3 extending generally horizontally away from the left hand
end of the second exposed panel face 12a.sup.3. A male protuberance
32a.sup.3 having an arcuate end portion 42 is provided.
In FIG. 3, the male end 14.sup.3 has a first retaining leg 22.sup.3
which is provided with a generally arcuately formed socket 24.sup.3
and which terminates in a first retaining leg 26.sup.3 having a
spacer rib 44. As shown in FIG. 3, the female end 16a.sup.3 is
swung from the dotted line position shown in FIG. 3 to the solid
line position shown in such Figure so that the arcuate end 42 on
the male protuberance 32a.sup.3 is seated firmly in the socket
24.sup.3 on the male end 14.sup.3 of the first panel 10.sup.3 ; and
so that the second retaining leg 30a.sup.3 rests against the spacer
rib 44 projecting from the first retaining leg 26.sup.3 on the male
end 14.sup.3 of the first panel 10.sup.3.
The spacer rib 44 provides a pressure surface for the second
retaining leg 30a.sup.3 on the female end 16a.sup.3 of the second
panel 10a.sup.3.
As shown in the left hand portion of FIG. 3, the drainage cavity
34.sup.3 is defined by the first end leg 22.sup.3 of the first
panel 10.sup.3, the socket 24.sup.3, the retaining leg 26.sup.3,
the left hand portion of the spacer rib 44, and the male
protuberance 32.sup.3 on the end of the second retaining leg
30a.sup.3. The fastener 36 is inserted through the right hand
portions (FIG. 3) of the first retaining leg 26.sup.3 and into the
web 38 of the C-beam 40 and is hidden by the second retaining leg
30a.sup.3.
As shown in FIG. 4, another embodiment of a first panel 10.sup.4 is
similar to the priorly described embodiments but the male end
14.sup.4 is provided with a male retaining rib 46 on the first
retaining leg 26.sup.4 and the female end 16.sup.4 of the first
panel 10.sup.4 is provided with a female retaining rib 48 on the
second retaining leg 30.sup.4. As shown in FIG. 5, the male
protuberance 32.sup.4 on the second retaining leg 30a.sup.4 on the
second panel 10a.sup.4 engages or is received in the socket
24.sup.4 on the first retaining leg 26.sup.4 of the first panel
10.sup.4. The male retaining rib 46 on the first retaining leg
26.sup.4 of the first panel 10.sup.4 and the female retaining rib
48 on the second retaining leg 30a.sup.4 of the second panel
10a.sup.4 form cooperating means for preventing the sidewise
movement of the female end 16a.sup.4 of the second panel 10a.sup.4
away from the first end leg 22.sup.4 of the first panel 10.sup.4,
allows for the expansion and contraction of the female end
16a.sup.4 of the second panel 10a.sup.4 with respect to the male
end 14.sup.4 of the first panel 10.sup.4, and also positively
positions the female end 16a.sup.4 of the second panel 10a.sup.4
with respect to the male end 14.sup.4 of the first panel
10.sup.4.
It will be noted from a consideration of FIG. 5 that the male
retaining rib 46 on the first panel 10.sup.4 and the female
retaining rib 48a on the second panel 10a.sup.4 define a drainage
cavity 34.sup.4.
The fastening means (FIGS. 6,6A,6B) utilized to connect the first
retaining leg 26.sup.4 on the male end 14.sup.4 of the first panel
10.sup.4 to, for example, one of the flanges 50a,50b (FIG. 6) of

(FIGS. 6,6A). As shown particularly in FIGS. 6 and 6A, the clip 52
has a back portion 52a (FIG. 6A) and a central slot 52b from which
a front member 52c (FIG. 6A) is bent to the left and provided with
a female retaining rib 52d (FIG. 6A) adapted to receive and engage
the male retaining rib 46. As shown in FIG. 6, the top and bottom
bifurcated portions 52e,52f are slipped under the edges of the top
flange 50a and the bottom flange 50b respectively of the C-beam 40
to secure the first retaining leg 26.sup.4 of the first panel
10.sup.4 to the beam 40.
It will be understood to those skilled in the art that while the
female retaining rib 52d on the clip 52 is shown with a rounded
end, it may also be provided with a flat end.
Also, as shown in FIG. 6B, if, for example, the C-beam 40 were
discontinuous behind the male retaining rib 46 and the female
retaining rib 48 and the positions of the male retaining rib 46 and
the female retaining rib 48 (FIGS. 4 and 5 and 6) were reversed,
then a retaining clip 52' shown in FIG. 6B may be employed.
In a beam of tbe type shown in FIG. 7, the male end 14hu 7 of a
first panel 10.sup.7 is provided with a generally W-shaped male

female retaining rib 48a.sup.13 on the second retaining leg
30a.sup.13 on the female portion 16a.sup.13 of the second panel
10a.sup.13.
The embodiment shown in FIG. 15 is similar on its male end
14.sup.15 to the panel 10.sup.11 shown in FIGS. 11 and 12. The
female end 16.sup.15 of such first panel 10.sup.15 has the second
end leg 28.sup.15 formed in a substantially Z-shape to provide a
narrow space D (FIG. 16) between the forward portions of the first
end leg 22.sup.15 of the first panel 10.sup.15 and such second end
leg 28a.sup.15 of the second panel 10a.sup.15. The drainage cavity
34.sup.15 (FIG. 16) is provided either in the end space between the
end of the male protuberance 30a.sup.15 and the end of the socket
24.sup.15 or between the clip means 60.sup.15 and the top end
portions of the second end leg 28a.sup.15 of the second panel
10a.sup.15.

SUMMARY OF THE ACHIEVEMENTS OF THE OBJECTS OF THE INVENTION
It will be recognized by those skilled in the art that the objects
of this invention have been achieved by providing an improved joint
assembly 10 (FIGS. 1,2, for example) having a joint which provides
an interlock between two adjacent panels 10, 10a and which prevents
side movement or front displacement of the second panel 10a with
respect to the other planel 10; has a joint which provides a
drainage cavity 34 at such joint; will be self positioning with
respect to an adjacent panel 10a; has a joint which will provide
for a sheet metal socket fastener 36 a clip fastener 52,52',
adhesive or the like, all of which are hidden; has a joint which
will be esthetically pleasing and not appear to be a typical box
seam bond; has fastening means 36 on only one end of the panel 10
thereby reducing the number of fastening devices 36 and the cost of
the installation labor; prevents forward movement of the female
portion 16a of the second panel 10a and sidewise movement of the
female portion 16a of the second panel 10a of the joint assembly
with respect to the male portion 14 of the first panel 10 of the
joint assembly; and positively positions the female portion 16a of
the joint assembly with respect to the male portion 14 of the joint
assembly.
While in accordance with the patent statutes, preferred and
alternative embodiments of this invention have been illustrated and
described, it is to be particularly understood that the invention
is not limited thereto or thereby.
