Description
1~8917Z
This invention is directed to an interlocking construction panel, which, when interlocked with an identical panel, will present a smooth flat surface on one side, with a plurality of longitudinal integral channels projecting from the opposite side.
A principal object is to provide a novel interlocking preferably metallic, construction panel which may be readily enjoined in interlocking relationship with identical such panels, without the need for separate structural frame supports, and at the same time achieve maximum strength, economy of manufacture, and ease of inter- ~-locking.
It is a further object to provide an interlocking constru-ction panel adapted for interlocked engagement with other identical panels, said panel comprising: a planar wall of elongate rectangular configuration; one longitudinal edge of said planar wall having an integral open channel projecting outwardly and downwardly therefrom with a bottom in parallel alignment therewith, the side walls of said channel projecting downwardly and inwardly at an angle no less than 15 and nor more than 18 from said planar wall; said bottom of said channel having a longitudinal, central thickened protion;
said open channel having an inwardly projecting longitudinal lip adjacent the open top thereof on the side thereof remote from said panel; the other side of said channel having a pair of inwardly -projecting members, one in alignment with said planar wall and one ; therebeneath; the other longitudinal edge of said planar wall having downwardly projecting interlock integral longitudinal parallel members, one adapted to be restrained within said pair of inwardly projecting members on one side of said open channel, the other being adapted for snap-lock engagement with said inwardly projecting longitudinal lip on the other side of said open channel.
These and other objects of the invention will become '~

apparent with reference to the accompanying drawings in which:
Figure 1 is a perspective view of a panel;
Figure 2 is an end elevation of the panel according to Figure l; and Figure 3 is a sectional view of a channel portion of a panel in interlocking engagement with interlocking elements of a companion panel.
Detailed reference will now be made to the drawings where-in like reference numerals will identify like parts.
The panel 10 includes a longitudinal channel indicated generally at 12, in Figure 1. Panel 10 includes a lip portion 14 which projects inwardly along channel 12, lip portion 14 being slightly thicker than the thickness of the balance of panel 10.
Longitudinal lip 14 terminates in an outer edge which slopes down-wardly and inwardly at an angle of 15 (see Figure 2). Interior wall 16 of channel 12 slopes downwardly and outwardly, also at an angle of 15. Bottom 18 of channel 12 is provided on its upper surface with a longitudinal thickened portion 20, having a downwardly ' projecting notch 22 longitudinally therein, as is seen most clearly in Figure 3. Wall 24 of channel 12 projects upwardly and outwardly from bottom 18, at an angle of 15, and terminates in an inwardly projecting enlarged portion 26 having a flat bottom surface which projects slightly upwardly, and a convex arcuate upper surface, to facilitate interlocking with an adjacent panel, as will become clear ;:
hereinafter.
A longitudinal inwardly projecting finger-like member 28 is integral with wall 16, member 28 terminating in a concavely curved portion 28a.
"
The longitudinal edge of panel 10 remote from channel 12 terminates in a downwardly extending, generally circular bead portion - 3 _ .~ ....
-30, having a forwardly projecting lip portion 30a. The portion of bead 30 above lip 30a extends upwardly and inwardly at an angle of 15, as is seen most clearly in Figure 2. Inwardly from bead 30, a long~udinally extending downwardly projecting finger 32 terminates in a thickened portion 32a which is generally triangular in cross-section, the bottom of said triangle being slightly rounded, and terminating in a flat surface at the top thereof, projecting inwardly from finger 32 proper. The upper surface of thickened portion 32a is flat and is in alignment with the bottom surface of enlarged portion 26 of wall 24, when in interlocking engagement.
To assemble a panel into interlocking engagement with another, identical panel, lip 30a of bead 30 is inserted under ' longitudinal lip 14, with thickened portion 32a of finger 32 being directly above the convex arcuate upper surface of enlarged portion 26 of wall 24. Manual pressure on the surface of panel 10 above finger 32 will cause the angled wall of portion 32 thereof to slide against the convex arcuate upper surface of portion 26 until locking is achieved when the panels are interlocked as illustrated in Figure 3. It will be appreciated that as lip 30a of circular bead 30 serves as a fulcrum, as panel 10 is levered downwardly, the circular bottom portion of bead 30 will come to its secure position i inside concave trough portion 28a of member 28, as also clearly ! illustrated in Figure 3.
~J
Thickened portion 20 of bottom 18 strengthens the channel, and it has been found that without this reinforcing thickness continued flexing of an assembled structure of panels according to the invention, such as when used in the construction of a truck body, J there is a tendency for the panels to loosen. Further, notch 22 of thickened portion 20 provides an improved spring-like effect as the panels are being interlocked, and thus facilitates assembly.
~ - 4 -, 10891~Z
It has further been found that while the sizes of panels according to the invention can be enlarged, pro rata, it has been found that if the slopes of the channel sections are maintained no less than 15 and no greater than 18 it is possible to avoid a structure which is either too rigid, or too flexible respectively.
Referring to the convex arcuate upper surface of enlarged portion 26 of wall 24, it has also been discovered that if this curvature is too great, interlocking engagement with portion 32a of finger 32 becomes difficult, or if this curvature is made rela-tively flat, interlocking proves equally difficults.
The novel constructions disclosed herein permits a pluralityof panels to be readily enjoined in interlocklng relationship such that when assembled, there is no necessity for separate structural frames. The shape of the panel sections disclosed above has been designed after careful experimentation, in order to achieve maximum strength, greatest economy of manufacture, greatest ease of inter-locking, and greatest permanency of interlocked engagement.

Bottom 18 of channel 12 is provided on its upper surface with a longitudinal thickened portion 20, having a downwardly ' projecting notch 22 longitudinally therein, as is seen most clearly in Figure 3. Wall 24 of channel 12 projects upwardly and outwardly from bottom 18, at an angle of 15, and terminates in an inwardly projecting enlarged portion 26 having a flat bottom surface which projects slightly upwardly, and a convex arcuate upper surface, to facilitate interlocking with an adjacent panel, as will become clear ;:

The upper surface of thickened portion 32a is flat and is in alignment with the bottom surface of enlarged portion 26 of wall 24, when in interlocking engagement.
To assemble a panel into interlocking engagement with another, identical panel, lip 30a of bead 30 is inserted under ' longitudinal lip 14, with thickened portion 32a of finger 32 being directly above the convex arcuate upper surface of enlarged portion 26 of wall 24. Manual pressure on the surface of panel 10 above finger 32 will cause the angled wall of portion 32 thereof to slide against the convex arcuate upper surface of portion 26 until locking is achieved when the panels are interlocked as illustrated in Figure 3. It will be appreciated that as lip 30a of circular bead 30 serves as a fulcrum, as panel 10 is levered downwardly, the circular bottom portion of bead 30 will come to its secure position i inside concave trough portion 28a of member 28, as also clearly ! illustrated in Figure 3.
