PREFORMED AND NESTABL~ PANELS FOR ROOFS, WALLS AND THE
LIKE
BACKGROUND OF TEIE INVENTION
This invention relates to new and useful improve-
ments in preformed metal or synthetic plastic panels de-
signed primarily for use in the formation of roofs or walls
and the like.
Counter-curved corrugated panels are well known
and when these are joined together, one edge corrugation
overlaps the side edge of the adjacent panel and nut and
bolt assemblies or rivets extend downwardly through the
junctions to join the panels together. Because of the con-
struction of such panels and because of the vertical secu-
rement thereof, sealing materiaLs must be placed between
the overlapping edges of the panels in order to prevent
the ingress of moisture and the like either under the lip
of the panel or through the apertures formed for the ver-
tical fastening meansO
Furthermore, with the advent of other shaped
panels, the counter-curved configuration is finding less
favor and is being replaced by panels having a plurality
of raised and depressed troughs with horizontal upper and
lower portions. These not only take less material than

counter-curved corrugated sheets,but also provide a more decora-
tive and aesthetic structure. However, the formation of such
panels presents some difficulty in joining adjacent panels
together. If a standard overlap of one trough with the other
is provided,then considerable waste material occurs because
of the widths of the troughs in such structures.
Furthermore, said type of overlapping connections
require vertical securement means once again leading to leakage
and difficulty in sealing one between the other. Examples
of such structures are shown in United States patent no: 3,323,268
and 3,320,711.
Another requirement for such panels is ease of stack-
ing one upon the other for storage and transportation purposes
and attempts nave been made to provide longitudinally extend-
ing side edges on panels wnich engage with one another relative-
ly efficiently, but due to the configuration thereof, are impos-
sible to stack in interfacial re]ationship thereby taking U?
the maximum of space for storage and transportation.
SUMMARY OF THE INVENTION
The present invention overcomes these disadvantages
by providing a preformed trough type panei having longitudinal
side edges which engage one with the other when the panels
are adjacently connected together and which may be connected
together and also include means on one side edge to overlie
and shield the junction and theother side edge of the adjacent
panel. Such panels are also capable of stacking relationship

one with the other in theminimum of space for storage and trans-
portation purposes. It will be appreciated that when panels
are stac~ed onto one another, some spreading of the lowermost
panel in the stac~ may occur. However, this will not permanent-
ly deform the configuration.
In accordance with the invention there is provided
a substantially rectangular panel construction for adjacent
connection together to form walls, ceilings and the like, each
panel being preformed and comprising a plurality of alternately
situated depressed and raised troughs, a first side edge form-
ed on one longitudinal side of the panel and a second side
edge formed on the other longitudinal side edge of the panel,
said first side edge of one panel engaging said second side
edge of the adjacent panel whereby a portion of said first
side edge overlies and shields the second side edge of the
adjacent panel and the junction between said ad~acent panels,
said first edge and said second edge including vertically situat-
ed portions which are in partial interfacial relationship when
said panels are adjacently connected together, and fastening
means e~tending through said vertically situated portions in
said partial interfacial relationship, for adjacently connect-
ing said panels together.
Another advantage of the invention is to provide
a substantially rectangular panel construction which may be
formed in a horizontal sheet or a curved sheet as desired.

secured together by horizontally extending fastening meanssuch as blind rivets or the like and in which the longitu-
dinally extending edge of one panel may overlie and shield
the longitudinally extending edge of the adjacent panel and
the junction between the adjacent panels.
~ et another advantage of the invention is to pro-
vide a panel construction of the character herewithin des-
cribed in which any form of trough configuration may be used
or alternatively, the portion of the panel between the long-
itudinally extending side edges may be planar if desired.
Yet another advantage of the invention is to pro-
vide a device of the character herewithin described which
is simple in construction, economical in manufacture and
o-therwise well suited to the purpose for which it is design-
ed.
With the foregoing in view, and other advantages
as will become apparent to those skilled in -the art to which
this invention relates as this specification proceeds, the
invention is herein described by reference to the accompany-
ing ~rawings forming a part hereof, which includes a descrip-
tion of the preferred typical embodiment of the principles
of the present invention, in which:

VETAILED DESCRIPTION
The individual panels collectively designated lO
may be formed from sheet metal or sheet synthetic plastic either
on a brake or preferably through a rolling mill in which a
strip ofmaterial is passed through the rolling mill and preform-
ed either in a continuous length which may be cut into conven-
ient lengths, or by passing individual sheets of material
tnrough the mill to form individual panels.
Such panel formation is well known and it is not
believed necessary to describe same further~
In tne panel 10 illustrated herewith~ a plurality
of troughs 11 are formed with trough 11 being depressed and
trough llA being raised. Each trough includes the horizontal
longitudinally extending portion 12 and outwardly diverging
side panel portion 13. However, it will be appreciated that
any configuration of trough can be utilized pro-
. ~ ' s `''~1

viding the trough configura~ion is such that one panel
will nest within the other for storage and transportation
purposes.
It will be appreciated that the portion of the
panel between the longitudinally extending side edges, may
be planar, if desired.
A first longitudina~ side edge is formed on the
panel and is collectively designated 14 and a second long-
itudinally extending side edge formed on the opposite side
of the panel and collectively des.ignated 15 and the confi-
guration of the side edges 14 and 15 is different as will
be apparent from a perusal of the drawings.
Dealing first with the side edge 14, it extends
upwardly from a relatively shorl outwardly and upwardly ex-
tending side wall 16 which extends from the planar base 12
of the outermost depressed trough. A substantially vertical :
portion 17 extends upwardly from the upper edge 18 of the
portion 16 and a horizontal portion 19 extends outwardly
from the upper edge 20 of the vertical portion 17.
A relatively short lip or flange 21 extends out-
wardly and downwardly from the outer edge 22 of the hori-
zontal portion 19 as clearly shown in the drawings.
The second side edge 15, also extends from the
relatively short wall portion 16 of the other uppermost de-
~, .
3Si~,~
pressed trough 12. From the upper edge 17 of this portion
16, there is formed a relatively short substantially vertical
portion 23 and an upwardly and inwardly extending portion 24
extends from the upper edge 25 of this relatively short vertical
portion 23. A substantially horizontal portion 26 extends
outwardly from the upper edge 27 of the upwardly and inwardly
extending portion 24.
It will be observed that the horziontal portions
19 and 26 of the two side edges 14 and 15, lie in the same
plane as one another and, in this embodiment, in a plane above
the plane of the portion 12A of the raised trough llA. However,
if desired, the plane of the horizontal portions 19 and 26
and the portion 12A may be similar.
From the foregoing and from a perusal of Figure 3,
(which is schematic only) it will be observed that the panels
; may nest substantially one within the other in stacked relation-
ship Eor storage and transportation purposes thus taking up
the minimum of space for this purpose. Spreading of the lowermost
panels (not illustrated) that will occur due to the weight
and similar dimensions of the panels there~ore will not permanent-
ly distort the configuration of the lowermost panels.
When it is desired to secure adjacent panels together,
the first longLtudinal side edge 14 is overlapped upon the
second side edge 15 of the adjacent panel as clearly shown
in Figure 2 so that the vertical portion 23 of tne second side

edge is in partial interfacial relationship with the verti-
cal portion 17 of the adjacent panel. This means that fas-
tening means 30 may extend between these vertical portions
in a horizontal manner, said fastening means taking the form
of blind rivets or any other desired fastening means. It
will also be observed that the horizontal portion 19 of one
panel completely overlies and shields the horizontal portion
26 of the adjacent panel with the lip or flange 21 extending
outwardly and downardly over the junction 27 and that this
shielding also extends to the junction between the adjacent
panels thus eliminating the necessity for sealant material
under the majority of circumstances. Further fastening means
30A extend through these horizontal portions 19 and 26 similar
to fastening means 30.
It will also be obser~ed that the adjacent side
edges 14 and 15 oE the adjacent panels nest together when fas-
tened by means 30 thus assistiny in the seal therebetween and
also adding a stiffening effect to the junction between adja-
cent panels and hence to the entire structure.
Finally, it will be noted that Figure 2 shows, at
the left hand side thereof, a building structural member 28
in the form of a purlin or girt or the like, to which the
panels may be secured by the vertical fastening means 30A.
Since various modifications can be made in my in-
~Z35i~
vention as hereinabove described, and many apparently wide-
ly different embodiments of same made within the spirit and
scope of the claims without departing from such spirit and
scope, it is intended that all matter contained in the ac-
companying specification shall be interpreted as illustra-
tive only and not in a limiting sense.
