1 Claim, 18 Drawing Figures PATENTED SEP] 8 I975 SHEET 3 [IF 5 PANEL JOINT ASSEMBLY wlru nnxmxcs CAVITY i 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 m 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 multi- 1 plicity of featuresthe unique detail joint configuration of my invention provides.

l am aware of the following prior art patents:

The joint disclosed in US. 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. v

The joint disclosed in US. Pat.

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. r

The first panel 10 has a first exposed panel face 12 (FIGS. 1,2) provided on its right hand end with a first endportion 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 isprovided with a centrally disposed male rib 18 (FIG. 1) flanked onopposite sides thereof by smaller reinforcing ribs 20aand 20b. Themale end 14 has a first en'd"leg 22 (FIGS. 1,2) extending inwardly from the first e'xposed 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 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 firs 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.
